Description

TOOL WIRE TIE IMPELLER DESCRIPTION MECHANISM The present invention relates to a tool clamping wire and more particularly to a tool aided by power portable to attach the rodding to be used in reinforced concrete, or to link another object or objects with twisted wires. Concrete is a commonly used construction material. The forms are configured and the concrete is emptied into the shapes so that it hardens and then the forms are removed. To reinforce the concrete, a metal grid of "barbed" bars can be placed inside the forms, so that when the concrete hardens, it is reinforced by the rodding. The grid can be formed by a set of horizontal rods, which intersect with a set of vertical rods. To keep the rodding grid in place, it is common to tie the cross joints of the horizontal and vertical bars that intersect with a wire. This is a time-consuming process when done by hand, using standard 16 gauge annealed wire (approximately 4710.56 kg / cm2 (approximately 67,000 psi)). A conventional manual clamping, using pliers or a similar tool, involves forming a loop of a wire filament about a transverse seal and pull to tighten, so that the loop seal includes the seal with the ends of the wire rotated to prevent collapse . Two full turns of 360 ° each, will keep the mooring in place. Sometimes the wire is bent to prevent the wire from breaking at the mooring / turning point. Because the gasket clamping must be maintained while the concrete is emptied subsequently thereon in form and may (when the rodding is pre-assembled off-site) must be kept safely while grid rodding is lifted , moved and manipulated, the wire tie must be strong and resistant. Due to the difficulties associated with manual tying, it would be advantageous to develop a light weight, portable and reliable mescan wire tool. An advantageous mechanical wire tie tool would be able to: (a) form a loop of a wire strand over the joint to be tied - for this purpose a movable set of beads can be used with the beads placed on the joint and closed, the wire is fed through the beads and the wire is then released from the beads to form a loop over the joint; (B) cutting and twisting the ends of the wire in the loop over the joint - for this purpose a winder / cutter can be used to cut the ends of the wire loop, to keep the loop under tension and to twist the ends, to form a "knot" without breaking the wire before the knot forms and removing the cut ends of the wire loop as the knot is formed to leave the knot in place; (c) Pull back the slack at the ends of the loop, after it is placed over the joint and then keep the loop under tension as the ends are turned and the knot is forming, to form a strong knot - to For this purpose, some kind of backward traction mechanism and tension device must be used; and (d) feeding a hard wire through the device without poor feed through the beads or in any other way - for this purpose, a heavy duty wire drive must be used and other portions of the device must be designed to Cooperate to handle a hard wire supplied at high speed. An advantageous mechanical wire tie machine must be able to perform all the functions mentioned in the above quickly and reliably with a hard wire and must be capable of being operated by a single person. The mechanical lashing tools of the prior art have not been completely satisfactory in fulfilling all the desired characteristics. U.S. Patent No. 3, 391, 715 of Thompsom and U.S. Patent 5, 217, 049 to Forsyth show wire tie devices showing heels that are movable; cutters that include jaws with shear plates (a shear force disk); and feeding systems with a wheel friction unit in pairs, standard. The backward traction is performed by reversing the driving wheels. Other variations on a device that has a bead and that includes shear disc cutters (or a movable cutter disk or a single "moleta" blade), conventional feeding systems such as standard wheel or wheel friction devices reverse motors for backward traction are shown in U.S. Patent No. 4, 362, 192 to Furlong et al .; U.S. Patent No. 4, 117, 872 to Gott et al. (double-wire systems with beads that are grooved and not fully closed), United States Patent No. 4, 354, 535, to Powell et al. (open slot); U.S. Patent No. 4,685,493 to Yuguchi; U.S. Patent No. 4,953,598 to McCavey (a single hook, open slot); and U.S. Patent No. 4,834,148 to Muguruma et al. (open slot with a semi-enclosed member). U.S. Patent No. 4,542,773 to Lafon discloses a wire tie machine with two lower jaws. Hand-operated wire tie machines are shown in U.S. Patent No. 5,178,195 to Glaus et al. and U.S. Patent No. 3,593,759 to Ooge. A major disadvantage of current mechanical wire tie devices is the inability to reliably replace the manual tie down. The wire is often fed poorly through the heels. The ends of the loop wire frequently do not twist under sufficient tension to create a strong knot, and / or the knot breaks as it is being rotated. The feeding systems can not withstand a fast advance of a relatively hard wire, nor the traction backwards or the windings incorporate the wire. It can be seen that there is a need for a mechanically aided, reliable wire tie tool. Preferably, the tool would include partially encased enclosed heels to channel a relatively hard wire loop around a high speed wire joint, a traction backward feature to retract the loop under tension to tighten the loop around the joint, a winder / cutter that extrudes a knot by twisting, knotting and cutting the wire (keeping the cutting ends under tension) and then spinning in full revolutions to twist the wire into a knot, while pulling it out of the winder separating it from the surface of work (as long as the knot does not break when forming) and reestablish control to immediately re-establish the tool for the next knot. The complete cycle must be completed in the space of approximately 2 to 3 seconds. The tool must be held by hand and powered by electricity or compressed air. It should weigh around 6.81 Kg to 9.0 Kg, be approximately 45.72 cm to 60.96 cm long (18 to 24 inches long) and approximately 10.16 cm to 15.24 cm in diameter (4 to 6 inches in diameter). The tool should be capable of improvement by standard 16 gauge annealed wire rated at approximately 4710.56 Kg / cm2 (67,000 psi) and which is commonly used in knots tied by hand, for example by handling a much harder wire , such as a 16 gauge "green" hard (uncovered) wire rated above 4710.56 Kg / cm2 and up to approximately 8 928.98 Kg / cm2 (127,000 psi) or greater. It is a specific object of the wire tie apparatus and method of this invention to provide those benefits of reliability and operation, which will allow a power tool to replace the manual clamp. The present invention provides an apparatus and method for tying a wire knot around an object. A preferred use for the invention is to tie a wire knot around the rodding, but many other uses for the invention also exist, for example tying a knot of wire around a slanted post, a sack of potatoes or an ice pack or any another object, or a combination of objects around which a wire knot is needed or desired. The apparatus of the invention comprises a tool for tightening a wire knot assisted by power. In the preferred embodiment, the tool is held by hand and powered by electric power although the power of a battery or compressed air can also be used. The weights of the tool under 9.0 Kg (under 20 Lbs) (not including the winder and wire) and is approximately 45.72 cm long and approximately 10.16 cm to 15.24 cm in diameter. The preferred tool is designed to take a hard wire such as hard wires without "green" annealing preferred (up to about 8 928.98 Kg / cm2 or more). The wire tie tool of the invention includes a set of enclosed, movable beads to form a channel of a relatively hard wire loop around a high speed wire joint.; a spring-loaded retractable spool with clutch to maintain tension on the hard wire on the spool; a winder / cutter that extrudes a knot by knotting and cutting the wire (keeping the cutting ends under tension) and then turning in full revolutions to twist the wire into a knot, while removing the bobbin winder away from the work surface (for do not break the knot that is being formed); and a reset control to immediately reset the tool for the next lash. In a preferred embodiment, the wire lashing tool also includes a single reversible power source, for example, an electric motor, which transmits power to the three driving mechanisms including (i) a bead driver for closing the beads around the board that is going to be tied and then to reopen the heels; (ii) a bobbin winder for advancing and subsequently retracting the winder shaft, rotating and retracting the bobbin winder after the wire has been fed through the closed beads and a wire loop has been tightened around the bobbin. together, so that the knot is rotated and extruded; and (iii) a heavy-duty wire drive to feed the wire into the beads and through the openings in a winder head attached to the winder shaft, and then to retract the wire loop under tension to tighten the wire. loop around the board. It should be understood that the invention is not restricted to an electric motor. Any suitable power source, or combination of power sources, can be used, for example a motor or pneumatic motors, a hydrolytic impeller or drivers, an internal combustion engine (for example, a gasoline engine) and the like, connected to a suitable power source, for example a power line of 110/220 VAC, a battery, a source of compressed air, or the like. In the preferred embodiment, the driving mechanisms incorporate a clutch system of overload, differentials, gears and mechanical logic, in such a way that the various driving mechanisms open the heels, close the heels, feed the wire through the heels and the head of the winder pulls the loop, twists the knot, cuts the wire and resets the heels to the open position with only one pull on the trigger which drives the motor. An operator simply places the open heels on the rodding joint (or other object or objects around which the wire knot is to be tied) and presses the activator. Activation of the activator first transmits power to the bead impeller and the bobbin driver. This closes the heels around the joint, forming a completely closed loop, while advancing the head of the winder to its fully forward position to receive a length of wire. When the heels have been fully closed and the winder is clamped forward, a mechanism will direct the power to the wire impeller and the wire impeller will force a given length of the wire through a first conduit in a winder / cutter assembly around the wire. the winder head, around the bead loop and back through a second conduit in the winder / cutter assembly with the end of the wire clamped through a non-return device (excess wire through the clamp becomes waste and will be pushed out in the next cycle). A mechanism is set to detect when the wire has reached the non-return device at the end of the loop, and the motor is inverted. The heel impeller begins to pull back and the heels begin to open as the wire impeller pulls back on the wire with full force, pulling the loop off the heels and tightening the loop as it is released from the heels. Heels and pulled around the board. The wire impeller pulls the wire back under a preset tension (either 12.7 Kg or less of tension to 12.7 Kg or more of tension) and tightens the loop around the rodding. The loose wire is automatically rewound on the winder. When the wire driver has pulled the wire loop to tighten and the heel drive has opened the heels, the power is re-directed to the bobbin winder and the bobbin winder / cutter is activated. The winder begins to rotate, knot and cut the wire and rotates many revolutions to twist the wire into a tie. As the winder begins to rotate, the indentations placed in the barrel of the winder form knots in the wire fixed inside the winder head and as the winder continues to rotate, a cutter cuts the wire fixed inside the barrel of the winder. winder leaving the knots in the cut ends. The knots formed on the cut ends of the wire are then pulled through the conduits inside the winder to keep the wire under tension after it is cut. The winder retracts from the work surface as it rotates and so does at an equivalency speed the length of the clamp that occurs as it rotates, thereby extruding the knot away from the work surface. Then the tool is in a ready position and the operator can move to the next tie point. The combination of features provided by the invention allows a mechanical wire lashing tool to replace the manual lashing in a reliable, fast and efficient manner.

Corresponding reference numerals indicate corresponding components in all the various views of the drawings. The following description is the best mode currently contemplated to carry out the invention. This description should not be taken in a limiting sense, but is made solely for the purpose of describing the general principles of the invention. The scope of the invention should be determined with reference to the claims. In the discussion that follows, the invention will be described from two different perspectives. First and with reference to FIGS. 1 to 12, the wire lashing tool will be shown in a first embodiment, with an emphasis on the most basic form in which the tool works - this will serve to explain how the winder / cutter assembly rotates and extrudes a knot and how the wire impeller and heels cooperate with the bobbin winder / cutter. This discussion will serve as an introduction to the subsequent discussion of a second embodiment of the wire lashing tool in which a preferred drive will be described. Second and with reference to FIGURES 13 to 32, the tool will be shown in a second mode and the driving mechanisms will be explained in much greater detail - this will serve to explain how a single motor can drive three impellers (bead impeller, impeller the wire winder and impeller) with clutches, differentials, associated gears and mechanical logic, in such a way that each of the sub-assemblies of the wire lashing tool performs its function in the proper sequence. The first modality will be described under the heading "First Modality (Basic Operations!") The Second Modality will be explained under the heading "Second Modality (Impeller Mechanism)." Although there is much in common between the two modalities, each must be understood by itself To emphasize the difference as well as the similarities, different sets of reference numbers have been used for the two modalities: First Modality (Basic Operations) With reference to the perspective view of FIGURE 1, it can be understood that a first modality of the wire tie tool 20 of this invention, includes a wire driver and a back pull assembly 22; a winder / cutter assembly 24 (carried within the bearing block 30 and not visible in FIGURE 1); a retractable spool or reel assembly 26; and a bead assembly 28. Assembly, handling, power supply and associated control systems are also included and are indicated in FIGURE 1 as the bearing block 30, the housing of the gear case 32, the motor of the winder 34, feed motor 36, PC board 38 and handle holder 40. With reference to FIGS. 1 and 2, it can be understood that wire unit assembly 22 and bead assembly 28 are mounted on the bearing block 30 and that the winder / cutter assembly 24 is transported within the bearing block. The discussion that follows will describe each of the sub-assemblies in turn, and will then describe how the sub-assemblies connect and cooperate with each other to achieve the objects of this invention. Wire Drive and Rearward Drive Assembly Referring to FIGURE 3 and the more detailed views of FIGURES 3A to 3H, a first embodiment of the wire drive and the rearward drive assembly 22 can be viewed as a wheel drive. The mound 22 includes a frame bracket 42, which is connected to the bearing block 30 (not shown in FIGURE 3) and a pivot block 44, which is attached to the frame bracket. A feed roller 46 is conveyed on the shaft 48 of the feed roller conveyed in the pivot block 44 and the structure bracket 42. The co-operating feed holding rollers 50, 52 are transported on the roller shafts 54, 56 of the roller. power supply transported in the pivot block and the structure bracket. A helical gear 58 transmits power from the feed drive motor 36 (not shown in FIGURE 3) to the feed roll shaft 48 and the friction gears 60 cause the axes of the feed holding roller to move along with the feed roller. Feed roller shaft. It can be understood that the wire will be fed between the feed roller 46 and the feed holding rollers 50, 52. In a preferred embodiment, the contact surfaces of these rollers are grooved and are giving a rough texture to better hold the wire. Such texture can be imparted by sandblasting the surfaces. A separator 62 is used for the initial loading of the wire, lifting the wire from the slots in the drive rolls and directing the wire into the feed tube 64 (reference to FIGS. 1 and 2). With reference to FIGURE 4 and the more detailed views of FIGURES 4A to 4F, a second embodiment of the wire impeller and the rearward traction assembly 22A can be viewed as a belt unit. The assembly 22A includes a structure which is connected to the bearing block 30 (not shown in FIGURE 4) and which includes a pair of side panels 70, 72, an upper panel 74 and a lower panel 76. The structure is completed by a pair of end panels 78, 80 and a pair of belts 82, 84.

A set of feed pulleys 86 is transported between the side panels 70, 12 and a feed belt 88 is engaged in the pulleys. A cooperating assembly of feeder holding rollers 90 is transported between the side panels and a fastening band 92 is engaged on the rollers. The power of the supply drive motor 36 (not shown in FIGURE 3) is transmitted to the feed pulleys 86 and a drive tractor drives the drive wheels of the feed belt 88 and the holding band 92. It can be understood that the wire will be fed between the bands. The feeder belts are giving a friction surface; such a surface could be imparted using a polyisoprene material or other suitable material or coating. Spinning / Cutter Assembly With reference to FIGURE 5, the spinner / cutter assembly 24 can be understood to include a spinning head 100 cylindrical, axially fixed to a screw 102, which in turn is axially fixed to a star 104. screw collar 106 fixed to the bearing block 30 (not shown in FIGURE 5) engages the screw 102 and a star drive gear 108 transmits the power of the spinning motor 34 (not shown in FIGURE 5) to the assembly of the spinning The bushings 109 and 103 guide the assembly into the bearing block 30.

A first "inlet" conduit or duct 112 and a second "outlet" duct or duct 110 are formed in the head of the spinner 100. Although the first duct 112 is mentioned as the inlet duct and the second duct 110 is mentioned as the outlet conduit, it should be understood that these designations are for convenience of reference only and that the conduits are essentially identical and with orifices passing diagonally through the head of the spinner 100 and are adapted to receive the wire fed from the assembly impeller 22. A pair of cutters 114, 116 are held in the barrel of the bearing block 30 adjacent to the spinner head. The conduits 118 and 120 formed within the cutters 114, 116 are aligned with the conduits 110 and 112, such that the wire can be fed through the cutter 116 to the spinning head 100 and the spinning head through the cutter. 114. Additional details of the spinner / cutter assembly can be understood with reference to FIGURE 11 and FIGURE 12. With reference to FIGURE 11, it can be seen that the conduit 118 of the cutter 114 is adapted with a set of fasteners 180 to form a gag 182 without return. The fasteners are mounted with spring plates to push them against a wire 200 and the fasteners have a series of ridges forming teeth opposite to the direction by which the wire enters conduit 120. Although a similar non-return jaw must also be provided * , in the cutter 116, it should be remembered that the cutter 114 is the cutter adjacent to the outlet duct 110 of the head of the spinner 100 and a non-return jaw in the cutter 114 will serve to retain the wire that is fed through the assembly. The cutters 116 and 114 are mounted within the bearing block 30 (see FIGURE 2) and are leveled against the head of the spinner 100. The cutters 116 and 114 can be seen to have a flat mounting side 240 (FIGURE 11B) for the assembly against the bearing block and the curved surface 242 (FIGURE HA) that makes butt contact with the head of the spinner. With reference to FIGURE 12, it can be seen that there is an indentation 110A formed with a duct 110 of the spinner head. As shown in FIGURE 12, the shaped indentation 110A can be formed by widening the opening of the duct 110 in an elliptical fashion on the surface of the head of the spinner 100. An indentation 112A correspondingly (not visible in FIGURE 12). ) is formed in the same manner by widening the opening of the tube 112 from the opposite surface of the spinner head.

Heel Mounting With reference to FIGURE 6, the heel assembly 28 can be seen to include a first skin 140 placed on the bead mounting brackets 142 and 143 (with reference to FIGS. 1 and 8A) through the pivot point 144 , with the mounting brackets placed on the bearing block 30. A nearer heel arm 146 pivots on the mounting brackets 142, 143 and cooperates with the nearest heel 160 to effectively lock the first bead when engaged. A completely closed channel 164 within the bead 140 can accept within it the fed wire (Note, throughout the description that follows the term "clamp" can be used as a synonym for the term "bead") With reference now to FIGURE 8 and more detailed views of FIGS. 8A through 8F, the heel 140 can be better understood to include a bead arm 170 and a bead cover 172. A channel 164 is formed in the bead cover 172. When the bead cover 172 is to the bead arm 170, the two members cooperate fully to close the channel 164. A second bead 150 (again referenced to FIGURE 6) is placed on the bead mounting brackets 152 and 153 (not shown) through the point of pivot 154. A closer arm of the heel 156 pivots in the mounting brackets 152, 153 and cooperates with the nearest bead 162 to effectively lock the second bead when engaged. A channel 166 completely enclosed within the bead 150 can accept within it the fed wire. Although not shown separately, a bead arm 174 and bead cap 176 form the enclosed channel 166 within the second bead 150 in a shape corresponding to that of the first bead and as previously described with reference to FIGURE 8. The first and second beads 140, 150 meet when closed, such that the enclosed channels 164, 166 are aligned. A bullet tip 165 on the bead arm 160 of the first bead 140 (reference to FIGURE 8C) engages an indentation in the bead arm 174 of the second bead 150 and helps align the channels. As shown in FIGURES 6 and 7, a bead motor 220 mounted on the bearing block 30 drives a screw driver 222 to open and close the beads 140, 150. In the embodiment of FIGURE 6, a screw gear The auger moves the rotary movement of the thread of the screw 224 to the projections 226 and 228, which open and close the closest arms of the bead 146 and 156. In the embodiment of FIGURE 7, a pair of connecting rods 230, 232 connect the screw 222 to the closest arms of the heel 146 and 156 to open and close the arms of the nearest bead.

In both embodiments, the closest arms of the heel 146 and 156 urge the heels 140 and 150 to a closed position. In the closed position, the heel closures 160 and 162 keep the heel arm in the heel cover of the heel arms tightly together, to keep the channels closed (in the case of the first bead 140, as it is kept closed by the heel 140). the heel lock arm 146, the heel closure 160 maintains the heel arm and heel cover 172 tightly together, so that the channel 164 is enclosed, also in the case of the second bead 150, as it is kept closed by the bead lock arm 156, the bead lock 162 maintains bead arm 174 and heel cover 176 tightly together, such that channel 166 is enclosed). Also, in both embodiments, as the heel-closing arms 146 and 156 open, a space will be formed between the heel-closing arm and respective heels 140 and 150, and the heel-closures 160 and 162 will begin to releasing its retention on the respective heel arms (170 and 174 of the first and second heels), and the heel covers (172 and 176 of the first and second heels), to open space, which previously enclosed channels 164 and 166 This creates a sufficient "breaking" seam on channels 164 and 166, in such a way that a wire fed through the channels enclosed with the closed beads can be broken separating from the channels (now partially open) as the beads open. The opening of the heels can be better understood with reference to Figure 7, which shows the heel 140 in an open position, as compared to the heel 150 in a closed position (in the actual operation, the two beads will open and close simultaneously). and the non-workable configuration of Figure 7 with one heel open and the other heel closed, is provided solely to illustrate both of an open position and a closed position of the beads). Retractable Dewinder Now with reference to Figures 9 and 9A, the retractable bobbin winder assembly 26 can be understood to include a spring loaded winder 190 contained within the winder housing 180. A spring 192 is wound from a first point 194 about the winder to a second point 196 to create a spring load. The spring loading keeps the hard wire used in this invention from expanding on the winder and also incorporates any slack when the wire driver pulls back on the wire loop around the joint of the rodding to be tied. A one-way clutch 182 stops the forward speed of the winder and maintains tension on the wire.

Wire Tie Tool Having described each of the sub-assemblies, their cooperative work on the wire tie tool 20 will now be described. With reference generally to Figure 2, it can be understood that the heels have been closed around a grid joint to be tied. With the heels closed, the wire impeller and the backward reaction assembly 22 pulls a length of the wire 200 from a wire winder held in the reel assembly or reel winder 26. The wire removed by the wire impeller and the rearward traction assembly 22 is activated through the tube 64, by means of the cutter 116 of the winder / cutter assembly 24 and through the inlet conduit 112 of the winder head 100. Passing through the winder head 100, the wire is driven through the closed channels 164 and 166 of the beads 140 and 150 and back into the head of the winder 100, passing through the outlet conduit 110 of the head of the winder and passing out through the conduit 118 of the cutter 114 and through the non-return jaw 182 carried in the cutter 114. When the wire is passing and the end is fixed in the non-return jaw, a mechanism opens the beads , allowing the previously closed channel to be opened (as previously discussed in connection with Figures 6, 7 and 8) and activating the backward traction function of the wire drive assembly 22. The wire drive assembly 22 pulls back against the wire with a pre-set tension (22.7 kg to 45.4 kg (50 to 100 pounds)) with one end of the wire firmly fixed in the non-return clamp. This pulls the wire loop from the channel into the heels and pulls the loop tightly around the grate joint. Now with reference to the sequential series of the views of Figures 10A, 10B, 10C and 10D, the operation of the spinner / cutter can be better understood. In the ready position of Figure 10A, the head of the winder 100 is aligned with the cutters 116 and 114, such that the inlet and outlet passages 112 and 110 of the head of the spinner 100 are aligned with the cutters 116. and 114, such that the inlet and outlet ducts 112 and 110 of the spinner head align with the ducts 120 and 118 of the cutters. As can be seen in Figure 10B, a length of the wire 200 is fed through the tube 120 of the cutter 116, the tube 112 of the spinning head 100 (and, after forming a loop through the bead arms, not shown). in Figure 10), the tube 110 of the spinning head and the tube 118 of the cutter 114. The wire 200 is fixed within the jaw 182 without return (not shown in Figure 10) of the cutter 114. With reference to the Figure 10C, it can be understood that after the loop is pulled back and squeezed by the wire drive assembly (as discussed previously), and as the spinner begins to rotate in a counterclockwise direction , one end of the wire 200 is pushed into the formed indentation 110A in the conduit 110 and at another end of the wire 200 is pushed into the formed indentation 112A of the conduit 112. This initial movement of the head of the spinner 100 forms a knot in each a or from the ends of the wire 200. Next and with reference to Figure 10D, it can be understood that the two ends of the wire 200 are cut by a cutter 114 and 116 as the spinner continues to rotate. A knot 102 is twisted at the end of the wire loop adjacent to the head of the spinner 100. It can be understood that the knot 202 will continue to twist in place with another rotation of the spinner head, by pulling the knotted ends of the wire 200. through the ducts 110 and 112 of the spinner as it rotates. The knotted ends provide resistance within 110 and 112, keeping the wire loop under tension as the twisted knot is formed.

The head of the spinner 100 extrudes the knot 202 away from the working surface of the rodding joint as the knot is being formed and as the knotted ends of the wire 200 are being removed from the spinner. This is done by the cooperation of the screw 202 and the collar 106 (reference to Figures 2 and 5) which act to pull the spinning head 100 away from the working surface with each rotation movement of the spinner head. A very precise movement can be achieved. Satisfactory results have been obtained using a 0.63 cm (1/4 inch) screw clearance, where 4 revolutions of the spinner extrude a 2.4 cm (1 inch) knot. By extruding the knot as it is being formed, the knot is much less likely to break and ruin the twist. Activators, motors, associated control devices and the like are readily known in the industry and can be easily added to the invention described in the above to complete their work. The above description explains how the tool of wire tightening of this invention, forms a tight knot around a rodding joint, using a hard wire held under constant tension in a winder 26 with clutch, a wire impeller that sends a length of wire through an assembly 24, of spinner / cutter, forming a loop around a completely closed track within the bead assembly 28 and back through the spinner / cutter and through a non-return jaw, where it is firmly fixed. More importantly, the above description explains how the wire loop is tightened under tension supplied by the backward pull of the drive assembly, how the length of the wire is knotted and cut to maintain tension in the loop as the knot is forming and how the knot is extruded from the spinner head as the spinning head is removed from the work surface. The method of this invention has been generally described in relation to the previous work of the tool and includes: closing a pair of beads around a joint to be tied; drive a length of hard wire through a spinner / cutter, through a fully closed channel in the heels and back through the spinner / cutter to a jaw; open the heel channel to release the loop; Pull back on the loop to tighten it around the board; and knot, cut and twist the wire to extrude a knot separating it from the joint, while keeping the loop under tension as the knot is forming. Accordingly, it can be understood that this invention provides the benefits of a strong and uniform tie-down, using a hard wire and replacing the wires by hand. Second Modality (Drive Mechanism) The first embodiment described in the foregoing contemplates three engines, with a spinning motor (34), a wire drive motor (36), and a separate bead motor (220). The first embodiment also contemplates conventional electronic logic and control devices, as are well known in the field. Referring now to the perspective view of Figure 13, a second embodiment of the tool, having a single motor and a system of gears, fasteners, differentials and clutches will now be described. In this mode, a single motor will drive each of the spinner, the wire and the heels in sequence. In this way, the single-engine mode of Figure 13 can be thought to have a three-part drive mechanism, i.e., a spinner impeller, a bead impeller and a wire impeller. The discussion of the modality of Figure 13 will include a generality, a glossary and then a more detailed discussion, which is organized around the three drivers, followed by a discussion of the sequencing of the drivers and the operation of the tool. These three impellers of the embodiment of Figure 13 are generally described as follows (more detailed reference numbers in the related Figures will be introduced subsequently): Spinner Impeller - The spinner impeller drives a winder head by means of a spindle of the winder. During the tool cycle, the head of the winder first advances to a fully forward position and then forms knots by extruding the wire with rotary movement, while retracted in a controlled manner. Heel Impulse - The heel impeller drives the heels (or jaws) during the tool cycle, closing them at the beginning of the cycle to establish the wire path before the wire impeller feeds the wire and opens the heels ( jaws) when the wire impeller begins to pull back the wire. Wire Impeller - The Wire Impeller drives a pulley which pulls the wire from the supply winder, pushes it through the heels, then reverses to "pull back" just before the knot is spun and extruded by the spinning unit. These three impulse functions are coordinated using mechanical logic to achieve proper sequencing and drive flow during the tool cycle. A single reversible motor is used to drive the tool and a small electronic control module is used to start, stop and reverse the motor at appropriate points during the cycle. In general, the action will be described as "forward" and "backward" and the action will be further amplified in terms of clockwise or counterclockwise rotation of the motor as it is transmitted to the other various driving axes of the tool. The generality will guide the reader to the three drivers, their location within the tool, their general purposes in relation to each other and with the individual engine which drives all three. The glossary will then list most of the work elements of the three driving mechanisms. Because the number of fasteners, detents, arrows, bolts, springs, rollers work in a similar way and thus extend over three other driving mechanisms, distinctive nomenclature has been used which can be almost long. For example, we will describe a "wire lock release lever" and "a lever that inhibits the release of the wire lock", cooperating with such things as a "lever lever bolt that inhibits the release of the wire lock" ( 350 in Figure 26) and a "wire closure release tab" (352). It is believed that these terms are helpful for an understanding of the invention. To help avoid confusion, a glossary of terms is provided. Generalities With reference to the perspective view of Figure 13, it should be understood that this embodiment is not greatly different in external appearance from the embodiment of Figure 1. A 600 wire winder can be seen in the right rear part of the tool and a pulley 364 can be seen at the top of the tool, near the front. The wire impeller will activate the pulley to extract wire from the winder in the tool, two beads, an upper bead 400 and a lower bead 401 are observed in a vertical orientation at the front of the tool. The heel pusher will pull back on the heels to open them (and push forward to close them). It should be noted that in this particular configuration, the heels will open and close in the vertical plane (up and down) and it must be apparent that the heels may have been oriented in any other desired position. The vertical orientation chosen here allows the heels to be placed conveniently on a joint to be tied. Two handles, a trigger handle 602 on the back of the tool and a support handle 604 near the front of the tool, are provided for operator control. The trigger handle contains a trigger 606 and a reverse button 608. The support handle 604 provides convenient hand support for the operator to stabilize and support the tool. A long-handled version of the tool (see Figure 30) extends the range of the tool, allowing the operator, for example, to remain more comfortable while placing moorings near the operator's feet. The motor 300 (not visible in Figure 13) is mounted on the rear of the tool and is activated by means of an electrical cable 610. Of course, the tool can be driven by battery, hydraulics or other appropriate power source. For safety itself and others, the tool is surrounded by an outer housing 612, which holds many of the moving parts of the drive mechanism out of the path of the operator's hands and in any other way protects them from exposure. Other similarities and differences, between a modality of Figure 13 and the previously discussed modality of Figure 1, will become more apparent as this description proceeds. The embodiment of Figure 13 includes three impellers, a wire impeller, a bead impeller, and a spinner impeller, (not visible in Figure 13, but shown later with reference to other Figures). In this mode, each of the three impellers is driven by an individual motor. Taking the perspective view of Figure 13, it can be seen that the tool of this mode has a right side, where the winder 600 is transported; one left side; a front (or "front") part where heels 400 and 401 are transported; a back (or "point") from where the 610 power cable exits; an upper surface where the pulley 364 is transported; and a lower surface. Given this frame of references, the axes of the various impellers will be described as running "vertically" or "horizontally". A "vertical" axis is one whose axis runs generally up and down, from the top to the bottom of the tool. A "horizontal" axis is one whose axis runs generally parallel to a longitudinal axis of the tool, ie from the front to the rear. One difficulty in presenting a generality of the tool in Figure 13 is that there is no view of the tool, in which all three driving mechanisms and their associated driving axes can be seen clearly and understood at the same time. the horizontal axes are placed and obstruct a track of other axes from any angle. But the understanding of the tool and its driving mechanisms becomes direct once the orientation of the drivers is observed with reference to the axes that tend to define them, recognizing that this requires the cooperative view of several figures. In general, each of the main stamps and drivers will be identified and located now. Finally the lamp driver activei to the pulley 364 (Figure 13) which, when running in the forward direction, will extract wire from the winder 600, will feed the wire into the openings in the head of the spinner 332 (not visible in Figure 13, but shown for example in Figure 20) and through heels 400 and 401; and when it runs in reverse, it will pull back the wire, pulling the loop around the joint to be tied. With reference to Figures 24 and 25, it should be understood that the wire impeller itself includes a vertical axis 362 and a horizontal axis 340. In the discussion that follows, the vertical axis 362 will be referred to as the "drive shaft of the pulley". "and the horizontal axis 340, will be mentioned as the" differential output axis "and other details will be shown and discussed. For the present purposes, it is sufficient to note that the horizontal and vertical axes of the wire impeller and to orient the wire impeller inside the tool. With reference to Figures 13, 14 and 24, it can be understood that the horizontal axis 340 of the wire unit runs longitudinally inside the housing 612, on the left side of the tool and near the top of the tool and that the shaft vertical 362 of the wire impeller is perpendicular to the horizontal axis, extending inside the housing to the pulley 364 to which it will transmit power. Finally, the spinner impeller drives the spinner head 332 (Figure 20), which when it runs in the forward direction, will rotate and advance forward in a suitable position in the front of the tool, to receive the wire which will be fed by the wire impeller from its openings; and when it runs in reverse, then it will rotate and retract, cutting the wire and spinning and extruding the knot. With reference to Figure 20, it can be understood that the spinner impeller includes a horizontal axis 326. In the discussion that follows, this horizontal axis 326 will be referred to as the "spinner shaft" and other details will be shown and discussed. For the present purposes and with reference to Figures 13, 14 and 20, it is sufficient to note that the horizontal axis 326 of the spinner impeller runs longitudinally within the housing 612, near the lower center of the tool. Finally, the heel pusher pushes a lever 392 (Figure 15) in the lower part of the tool to which, when the impeller is running in the forward direction, it will push closed heels 400 and 401 (Figure 13), enclosing the joint that is going to be tied with the heels ready to receive the wire that will be fed by the wire impeller into the channel inside the heels; and when it runs in reverse, it will pull open heels, releasing the wire loop around the joint to be tied. With reference to Figure 15, it can be understood that the heel driver includes a horizontal axis 386 and another horizontal member 390 connected to the shaft. In the discussion that follows, the horizontal axis 386 of the heel impeller will be referred to as the "heel forward screw shaft" the other horizontal member 390 will be referred to as the "heel thrust bar" and other details will be shown and discussed. For now and with reference to Figures 13 and 15, it should be noted only that the horizontal axis 386 of the bead driver runs longitudinally within the housing 612 near the bottom of the tool and on the right side. The orientation of the three horizontal axes of the three respective impellers can now be seen, in general, with reference to Figure 26A, which is a front section view of the tool. The horizontal axis 340 of the wire impeller can be seen in the upper left; the horizontal axis 326 of the spinner impeller can be seen in the lower center; and the heel push bar 390 of the heel impeller can be seen on the right side (the horizontal axis 386 of the heel impeller is adjacent to the bead push bar, but can not be seen in Figure 26A). Finally and with reference to Figure 14, one more of the horizontal axis can be noted and that is the main axis 316 driven by the motor 300. The main drive shaft 316 will be referred to as the "differential input shaft" 316 for reasons which will become clear later. Now it can be better understood how and why the sequencing of the impellers is important for the proper work of the tool. Still with reference to Figure 14, the heels 400, 401 must be closed, while the head of the spinner 332 is advanced to the forward position: the heel impeller and the spinner impeller must move forward in series. The beads 400, 401 must be completely closed and the head of the spinner 332 fully forward before the wire drive feeds any wire: the wire drive pulley 364 must push the wire through, only when the heel impeller and the spinner driver are not moving their respective mounts. The impellers must go in reverse when the appropriate length of the wire is fed and coupled. Working in reverse, the pulley 364 of the wire impeller now pulls back on the wire, the heel impeller opens the heel 400 and 401 and the head of the spinner 332 rotates and retracts. This sequencing presents a problem for the logical control and the more detailed discussion, which follows this generality is best understood in terms of explaining this control. Two final observations that relate to the sequence are pertinent in this generality. First, a key to the understanding of sequencing is the recognition that the engine 300, when activated, drives two axes simultaneously and every time. The two constantly driven axes are (a) the differential input shaft 316 (reference of Figure 14), which is the power source for the rotor impeller and the wire impeller and (b) the leading bead the screw shaft 386 (reference to Figure 15), which is the power source for the bead impeller. Each one is clutched (the main overload clutch 314 with reference to Figure 14, and the heel overload clutch 384 with reference to Figure 15) in such a way that the power can be mitigated and the axes not always activated, but the point is that both of the differential input shaft 316 and the bead leading to the screw shaft 386 are always activated, and thus both can work together, or separately.

These two constantly activated axes, one, the bead carrying the screw shaft 386, transmits power directly to the bead impeller and thus is taken into account for one of the driving systems (the bead leading to the screw shaft 386 is the horizontal axis of the heel impeller, previously discussed in these generalities). The other of the two axes constantly activated, the differential input shaft 316 (reference with Figure 14), is taken into account for the other two driving systems. The differential input shaft 316 is fed into a differential 318, which divides the power for the wire impeller or for the spinner impeller. The differential transmits power to either the wire impeller, by means of the differential output shaft 340 (which is the horizontal axis of the wire impeller discussed previously in these generalities) and the drive shaft of the pulley 362 (which is the shaft vertical of the wire impeller previously discussed in these generalities, or to the spinner impeller, by means of intermediate drains to the spindle 326 of the spinner (which is the horizontal axis of the spinner impeller previously discussed in these generalities). The wire impeller is clutched (overload clutch 360 of the wire impeller on the vertical axis 362 of the wire impeller, reference to Figure 25) and the spinner impeller can be "held" or clamped, such that the power It is directed to one or the other of the spinner impeller or the wire impeller., clutches and detents or pins allow the three impellers to be combined as necessary. The tool is sequenced, at various points in the cycle, such that the bead impeller and either the spinner impeller or the wire impeller are being activated - for example, and with reference to Figure 14, the impeller heel together with the impeller of the spinner, in such a way that heels 400 and 401 close and the head of spinner 382 advances, while the impeller of the wire is clamped); in such a way that either the spinner impeller or the wire impeller, but not the bead impeller, is being driven (e.g., only the wire impeller, such that the 364 pulley feeds the wire through of the tool, while both the heel impeller and the spinner impeller are fastened); etcetera (other various combinations will be further discussed in detail in the description). This leads to the second point that will be made in this generality about the logical control system. The particular mode discussed here is essentially a mechanical logical system instead of an electronic logical system. The mechanical logic is chosen, among other reasons, for its durability overcome in an environment of anticipated operation, which can be dirty, muddy, cold or hot and the any other potentially hostile. It is believed that mechanical logic design has allowed this wire tie tool to be manufactured as a reliable, heavy duty tool with industrial application. Accordingly, it is believed that the example of mechanical logic, which is given in the present is the best way to exemplify the invention. It must be remembered, of course, that once the invention is understood, it is a simple design that chooses to incorporate its characteristics into electronic logic instead of mechanical logic. The translation of mechanical logic to electronic logic is well known in the industrial and it should be understood that this invention is suitable for both mechanical logic and electronic logic and that this invention covers both applications. Having completed these generalities, a glossary of terms will now be presented. Glossary Most of the components which are important for the operation and sequencing of the drive mechanisms of the tool are numbered and defined again in the following list (these components will be explained in more detail in the following and will be pointed out more particularly with reference to the various drawings, this glossary is for the reader's help only): Reference / Figure Element Description 300 Drive Motor AC / DC Reversible Motor Figure 14 Universal AC / DC (Approximately 1/4 to 1/3 HP) used to drive the tool and that has a motor shaft. 301 Motor shaft Motor shaft 300 302 Motor sprocket The integral small-diameter gear with the motor motor shaft 300 304 Gears The two planetary-driven gears two by the motor sprocket 302. 306 Plane plane The carrier for planetary gears 304 planetary. 30I Gear of The internal gear against ring which planetary gears 304 are driven. 310 Pinion interThe gear which is half driven directly by the planetary box 306.

Now having completed the generalities of the second modality and having established a glossary of terms, the detailed discussion that follows will describe the motor, the gears of the motor and the differential and each of the three driving mechanisms, in turn. The Engine, Gears of the Engine and Differential With reference to FIGURE 14, it can be understood that the engine 300 is a reversible motor, which activates the tool. Good results have been obtained using a reversible universal AC / DC motor of approximately one-quarter to one-third horsepower. A small electronic control module (not numbered separately) is used to start, stop and reverse the motor at appropriate points during the cycle. It should be emphasized that alternate power sources other than a reversible universal AC / DC motor can be used to practice the invention such as hydraulic motors / pistons, pneumatic motors and / or gasoline-powered motors. The pinion 302 of the motor is a small diameter gear integral with the motor shaft 301. The pinion 302 of the motor drives two planetary gears 304 held within the planetary case 306. The coaxial ring gear 308 is the internal gear, in which the planetary gears 304 drive against and the intermediate pinion 310 is driven by the planetary case 306 The intermediate pinion 310 enables the main activated gear 312. As will be explained below in relation to the differential input shaft 316 and the differential 318, the main pulse gear 312 is the power source for the rotor impeller and the wire driver by means of the main overload clutch 314. main overload clutch 314 is a torque limiting the clutch directly driven by the main gear 312. The main overload clutch 314 directly drives the differential input shaft 316. The differential input shaft 316 supplies power to the differential 318, the which is mounted on the differential case 320. The differential 318 is a device that divides the power, which activates either the spinner impeller or the wire impeller. Spinner Impeller Referring now to FIGURE 20 (and also with reference to FIGURE 14 for the ratio of the spinner impeller to the differential 318 and the differential case 320), it is to be understood that the spinner impeller is extracted from the differential. 318 by means of the pinion 322 of the spinner impeller, which is mounted to the differential case 320. The spinner drive pinion 322 drives the spinner gear 324, which imparts rotation to the spindle of the spinner 326. The spline 328 of the spinner impeller, in cooperation with the thread 330 driving the spinner, allows linear movement of the spindle 326 of the spinner during shaft rotation, while also transmitting torque. The head 332 of the spinner is the head which extrudes the knots after the wire has been fed through the head and pulled back. It works in the same way as the head 100 of the spinner described previously in relation to the first embodiment. The head 322 of the spinner cuts the wire against two cutting blocks 334, when the spinning head begins to rotate and the knot is extruded. In relation to the spinner, there are many other elements to see. These include elements of mechanical logic, which will be mentioned now, but are described in greater detail later. With reference to FIGURE 21, the oscillating connection 336 of the wire detector is a spring-loaded rotating tongue, which supports and activates the wire detector 338, when the wire is fed through the head 333 of the spinner. The wire detector 338 is a near switch. When activated, the wire detector 338 will stop and reverse the motor 300. It can be seen that a tab 337 on the oscillating connection 336 of the wire detector is in the path of the wire. As the wire is fed through the path, the wire will strike the tab 337, by actuating the oscillating connection 336 for contact with the wire detector 338, stopping and reversing the motor 300. When the wire is pulled back, the oscillating connection loaded by the spring, will push the tab 337 against the wire, holding the wire. wire in place. The tab 337 is removed to a point for this purpose.

Wire Impeller Referring again to FIGURE 14, it will be recalled that the differential 318 is the device that divides the power, which activates either the spinner impeller or the wire impeller, now with reference to FIGURE 24, see that the wire driver is taken from the differential 318 by means of the conical bevel gear 356 of the wire impeller, which is mounted on the end of the differential output shaft 340. With reference to FIG. 25, a bevel gear 358 drive, drives the wire driven by the bevel gear 356 drive, is directly connected to the wire drive overload clutch 360. On the contrary to the first embodiment of the wire tightening tool, discussed previously in relation to FIGS. 1 to 12 and which uses either a driving wheel or a driving belt to feed the wire from the winder to the heels, a Preferred mechanism for feeding the wire in the second embodiment of the tool is now being discussed in relation to FIGS. 13 to 32, it is a pulley 364 (see FIGURE 13) which is driven by the wire impeller and which feeds it and pull the wire back. Referring again to FIGURE 25, the wire drive overload clutch 360 is a clutch that limits the torque that supplies power from the motor 300 to the pulley 364 by means of the pulley drive shaft 362. The pulley 364 by itself can be better understood with reference to FIGS. 16, 17, 18 and 19. The pulley includes a pulley cylinder 370, which is a smooth steel cylinder around which the wire will be wound during its passage through the pulley and the pulley also includes a set of pulley rollers 502, 504, 506, 508, 510, 512, 514, 516, 518, 520 (the rollers are sometimes and when it is not necessary to distinguish between them, mentioned collectively with reference number 372). A planetary gear 368 of pulley activates the cylinder 370, and by itself is driven by the drive pinion of the cam 366. The pinion 366 is keyed to the drive shaft of the pulley 362 (discussed previously in relation to FIGURE 25). The rollers 372 are ved and loaded by the pulley roller springs 373 against the pulley cylinder 370. The roller gears 374 are keyed directly to the rollers 372 and are driven by a planetary gear 368. A conical feed guide funnel 376 receives and guides the wire from the winder 600 on the pulley 364 (see FIGURE 13). Again with reference to FIGURE 17, it can be understood that the feed guide block 378 guides the wire from the feed guide tunnel 376 to the first of the rollers 502 and the outward feed guide 380 guides the wire after it has been wound around cylinder 370 and passed back to roller 502, to feed tube 382. The feed tube 382 is an outlet tube, which feeds the wire leaving the pulley 364 on the head 332 of the spinner. It is off-line from the feed guide tunnel 376 to facilitate the passage of the wire around the cylinder 370. With reference to FIGS. 18A to 18J, it can be seen that a way to move the wire through the cylinder (from the feed guide 376 to the output feed tube 382) although the wire turns around the cylinder are by the use of many pulley rolls 372. The rollers are ved, the ves progressively moved from roller to roller. Taking as an example the first pulley roller, now identified as the roller 502 with reference to FIGURE 18A, it can be seen that this roller is ved with two slots 501 and 503. The slot 501 is substantially in line with the wire path that comes from the feed guide tunnel 376 and through the feed guide 378 (this orientation can be understood with reference to FIGURE 17). The slot 503 of the roller 502 is substantially in line with the path of the wire exiting the cylinder 370 through the feed guide 380 outwards. The wire is progressively passed around the cylinder 379 by many rollers, each of which has an individual groove progressively moving the wire from (for ease of discussion and observation FIGURES 18A to 18J) the left (where the slot 501 of the first roller 502 receives the incoming wire) to the right (where the slot 503 of the first roller 502 is adjusted to send the wire out of the pulley In this way, a second roller 504 has a single slot 505 slightly offset to the right of the first slot 501 of the roller (FIGURE 18B); a third roller 506 has a single slot 507 slightly offset to the right of the slot 505 of the second roller (FIGURE 18C); a fourth roller 508 has a single slot 509 slightly offset to the right of the slot 507 of the third roller (FIGURE 18D); and so on with the fifth, sixth, seventh, eighth, ninth, and tenth rolls 510, 512, 514, 516, 518, 520 and their respective slots 511, 513, 515, 517, 519, 521, each slot offset slightly to the right from the previous slot (reference to FIGURES 18E to 18J). Here, ten pulley rollers are used, but the number can be easily adjusted up or down, based on the desired application.

In relation to the wire impeller there are many other elements to see. These include elements of mechanical logic, which will now be mentioned, with reference to FIGURE 26A, but described in greater detail later. The wire clamping wheel 342 is engaged by the ratchet catch 344 of the wire. The lever 346 that releases the wire clamping is a lever with cams that drives the ratchet 344 of the wire. The lever 348 that inhibits the release of the wire clamp engages the wire holding pawl, preventing the wire 342 from uncoupling from the wire. The cam lever bolt 350 drives the lever 348 when released by the cam of the lever 354 which inhibits the clamped release of the wire. Heel impeller Referring again to FIGURE 14, it will be recalled that the intermediate pinion 310, which is driven by the planetary box 306, drives the main gear 312, which is the power source for the spinner impeller (discussed above). previously in relation to, for example, FIGURE 20) and the wire driver (discussed previously in relation, for example, FIGURE 24). In addition, the intermediate pinion 310 also provides power to the bead driver.

Now with reference to FIGURE 15, it can be understood that the bead overload clutch 384 is a torque that limits the clutch directly driven from the intermediate sprocket 310. The overload clutch 384 drives the screw shaft 386 leading to the bead , by turning it through the nut 388 that leads to the threaded bead, which is a threaded nut driven by the front screw shaft 386. The push rod 390 of the bead is connected to the screw shaft 386 of the forward bead, the push rod 390 of the bead is driven back and forth (opening and closing the bead) as the screw shaft 386 is rotated in the opposite direction to the clock hands and in the sense of the hands of the clock. The lower bead lever 392 is the lever at the bottom of the tool, which is actuated by the push rod 390 of the bead. The transverse axis 398 of the bead is a torsion axis, connected to (and driven by) the lower bead lever 392 and also connected to the upper bead lever 394 (see FIGURE 22). Referring again to FIGURE 15, the lower bead lever 392 is connected to the lower bead 401 (not shown in FIGURE 15) by the rod 396 connecting the lower bead and the upper bead lever 394 (see FIGURE 22) it is connected to the upper bead 400 by the connecting rod 397 of the upper bead. It can be understood that the push rod 390 of the heel cooperates with the transverse axis 398 to push both of the lower bead lever 392 and the upper bead lever 394. The connecting rods 396, 397 of the bead levers to the beads 400 and 401, pushes closed heels and opens them as the push rod pushes forward and pulls back. The heels 400 and 401 are movement jaws, which open to allow the tool to be placed around a bundle of rodding or other items to be lashed and then closed to establish the path of the wire, in such a way that The wire can be fed through the shape of a loop. The beads 400 and 401 generally function as described previously in relation to the first embodiment already discussed in relation to FIGS. 1-12. In addition to the operation described in the foregoing, the beads may have a set of moving inserts 402 (not shown in the figures) within the interior of the beads. The moving inserts are floating plates, which contain the encapsulation portions of the wire path and which are with cams in place when the heels are closed (forming the wire channel), and which are released as the heel opens (so it allows the wire loop to be pulled out of the heels). Alternatively, trap doors 404 (see FIGURES 31 and 32) on heels 400, 401 open and closed with a pivoting action as the heels are opened and closed, likewise form the wire channel and then release the loop in the appropriate time. The trap doors 404 are opposite the trap doors loaded with the spring, the trap doors being pushed by springs to open as the heels pivot to an open position. The trap doors 404 are opposite in that one opens to the left side and the other opens to the right side of the heels; and the heels of each trap door are in abutting contact with each other in such a way that when the heels are closed, the trap doors mutually inhibit each other from the opening, but as the heels begin to open (moving the heels of the doors separating them), the pressure of the spring on the trap doors push them to open. The cross-sectional view of FIGURE 32 shows the pivoting action of the door 404 in the upper bead 400, which best shows when the ends of the opposing doors 404 are in abutting contact with each other, when the beads are closed, the doors are inhibited from the opening.

In relation to the wire impeller, there are many other elements to be seen. These include elements of mechanical logic, which will now be mentioned, but described in greater detail later. Due to the need for the heel impeller to be sequenced in relation to the spinner impeller and the wire impeller (such that, for example, the wire impeller does not feed wire unless the heels are closed), and because the spinner impeller interacts with the wire impeller, many of the components introduced here include elements associated with the spinner impeller. With reference to FIGURE 28, the spinner retainer hub 406 is mounted on the front end of the spinner shaft 326 and serves to hold the spinner shaft in the forward position of the spindle. The hub of the spinner retainer includes an auxiliary spring roll 407 for compressing the auxiliary spring 424 and also has a bolt 409 for engaging a detent lock 412. The retainer roller 410 is mounted on the detent arm 408, which is an arm loaded with an oscillating spring which directs the spinner retainer hub 406 into place, when the spindle 326 of the spinner is in the forward position.

Lock latch 412 is a pivoted latch mounted on latch arm 408. Bolt 412 engages bolt 409 in latch bucket 406. The latch inhibiting lever 414 is a pivoted lever which inhibits latch latch arm. amiento. The finger 416 that releases the bolt is a pivoted finger, which moves the detent latch 412 in such a way that the latch hub 406 can rotate away from the latch roller 410. The latches and previous releases are related to the position of the latches. heels 400, 401 by a lever cam bolt 418 that inhibits the bolt (see FIGURE 29), the bolt release cam bolt 420, and the cam plate 422. The bolt that inhibits bolt 418 is supported by the cam plate 422, when the beads are closed (the push rod 390 is forward). The lock release finger cam bolt 420 is supported by the cam plate, when the beads are open (the push rod 390 is aft). The cam plate 422 has two cam features 423, 425, and is mounted on the push rod 390 of the bead. Now with reference to FIGURE 28, the auxiliary spring 424 is a compression spring that is compressed just before the spinner hub 406 of the spinner locks into position and provides the auxiliary torque to the spinner, when it cuts the wire. The detent roller 410 in the catch bucket of the spinner 406 compresses the auxiliary spring 424. With reference to FIGURE 14, the rear limit detector 426 is a proximity switch, which detects when the spindle 326 of the spinner has been retracted and then sends signals to the engine 300 so that it stops. Sequence of operations The operation of the tool for tying wires of the present invention is divided into three main operations previously described: driving the spinner, driving the bead and driving the wire. The spinner impeller drives the spinning head 332 through the spinner shaft 326. The spinner head knots by "extruding" the wire with rotating movement, while retractable in a controlled manner. The heel impeller drives heels 400, 401 during the tool cycle, closing them at the beginning of the cycle to establish the wire path and opening them after the wire has been driven through the path at the start of the traction back of the wire. The wire driver drives the pulley 364, which pulls the wire from the supply winder, pushes it through the beads 400, 401, then reverses to "pull back" just before the knot is extruded. These three functions are coordinated using mechanical logic, to achieve proper sequencing and power flow during the tool cycle. A single motor is used to drive the tool and a small electronic control module is used to start, stop and reverse the motor at appropriate points during the cycle. The sequence of operations of the wire lashing tool will now be described, along with certain variations that may occur. All the components have already been explained in relation to the figures. Those discussions will not be repeated here, but the reader can refer back to the glossary to help locate any of the components and the associated figure. 1. Initial Configuration. At the beginning of the cycle the heels 400, 401 are open, the axis of the spinner 326 is retracted and the driver of the wire is attached (the wheel 342 of the wire closure is coupled by a ratchet 344 for closing the wire and the ratchet The wire latch is locked in its bead by the lever 348 which inhibits the release of the wire lock - this keeps the stationary wire lock wheel 342, which in turn, prevents movement of the drive shaft 362 of the pulley and of the differential output shaft 340, thereby stopping the wire impeller). See FIGURE 26A. From this initial position, the tool is brought into operation as follows. In the discussion that follows, "Clockwise" and "Counterclockwise" will describe rotational directions as seen along (or generally parallel to) the longitudinal axis of the clock. tool, as seen from the back of the tool; "RPM" will mean revolutions per minute; and a "cycle" will mean a complete sequence of the tool to tie a knot. 2. Activation of the traction (activation of the intermediate pinion). From the initial configuration, the operator will place open heels 400, 401 around the joint of rods to be tied. When the heels are properly positioned, the operator pulls the main trigger 606. The pull or pull of the trigger turns on the drive motor 300 running in the counterclockwise direction. The motor pinion 302 drives the two planetary gears 304, which are pushed back against the ring gear 308, whereby the planetary box 306 rotates, which directly drives the intermediate pinion 310 in the opposite direction to the hands of the clock . This activates the main drive gear 312 clockwise, which is the power source for both the spinner impeller and the wire impeller. The planetary gear of the planetary gears 304 achieves the initial reduction necessary to obtain the engine at high RPM, decreasing a more practical speed range for the three driving systems. At this point in the cycle, the intermediate pinion 310 is activated, and ready to drive both the bead impeller and the spinner impeller as detailed in the following. 3. Power for the Heel Drive and for the Spinner Impeller (which closes the heels and advances the spinner shaft). In the operation sequence, the third stage simultaneously drives the bead impeller and the spinner impeller, while the wire impeller is clamped. The purpose of the third stage is to put the wire clamping tool in position to drive the wire to form the knot. In this way, it is imperative that the heels are completely closed and the spinner head is held in place, so that the wire channel is formed properly and is ready to receive the wire. At the end of this third stage, therefore, the heels will have closed and the spinner shaft will have advanced to its fully forward position. When both of these conditions have been met, the wire impeller will be unclamped and the third phase in the sequence will come to an end. 3 (a). Power for the Heel Drive (closing the heels). Movement in the counterclockwise direction of the intermediate pinion 310 (see step 2 above) directly drives the heel overload clutch 384, which in turn directly drives the front bead bolt 386, which turns counterclockwise. Counterclockwise rotation of the front screw 386 of the bead drives the front screw nut 388 forward, which in turn drives the push rod 390 forward. The forward movement of the push rod 390 of the bead rotates the lower bead lever 392 by means of a bolt coupling. The lower bead lever 392 in turn rotates the transverse shaft 398 of the bead, which then rotates the lever 394 of the upper bead. Connected to the upper and lower heel levers 392, 394 there are two rods 396 connecting the bead, which are connected to the beads 400 and 401. The rotation of the heel levers 392 and 394 push on the connecting rods 396, which close at the heels. It should be remembered that the intermediate pinion 310 is driven by both the bead driver and the spinner impeller simultaneously. In this way, the spinner is moving forward even when the heels are closing. The movement of what is discussed in the following, but for now, should be noted that heels 400, 401 if they are not obstructed (the situation where the heels are obstructed is discussed in stage 3 (b) below), will reach a fully closed position substantially more quickly, that the axis of the spinner 326 will reach its fully forward position. 3 (b). Power for the Spinner Impeller (which moves the spindle shaft forward and holds it). Movement in the counterclockwise direction of the intermediate pinion 310 (see step 2 above) rotates the main drive gear 312 in the clockwise direction. The main driving gear 312 directly rotates the main overload clutch 314, which rotates the differential input shaft 316 in the clockwise direction. This will supply the power to the differential 316. At this point in the cycle, the wire driver is still clamped (see step 1), therefore, the differential output shaft 340 is clamped. This causes the torque of the differential input shaft 316 to be transmitted to the differential case 320. By rotating in the counterclockwise direction, the differential case 320 directly drives the pinion 322 which drives the spinner which in turn rotates the spin gear of the spinner 324 in the counterclockwise direction. The driving gear of the spinner 324 engages the spline 328 of the spinneret, rotating counterclockwise, which in turn rotates the spinning thread of the spinner 330 in the opposite direction at the hands of the clock. Rotation in the counterclockwise direction of the spin thread of the spinner 330 and the drive groove of the spinner 328 causes the spinner shaft 326 and the spinner head 332 to move forward, while the spinning spline of the spinner 328 slides through the drive gear of the spinner 324. As the spindle of the spinner 326 is near its fully forward position, the catch lobe 406A on the hub 406 of Spinner retainer engages retainer roll 410 by lifting retainer arm 408 and pulling retainer spring 408A.

When the spinner shaft 326 reaches its fully forward position, the retainer roller 410 falls behind the detent lobe 406A in the spinner retainer hub 406, holding the shaft in the forward position. At this point, the detent arm 408 is held down by virtue of the bolt 409 on the catch hub 406 of the spinner, which engages the detent latch 412. Furthermore, since the retainer hub is held in position Auxiliary Spring Roller 407 compresses Auxiliary Spring 424. As previously mentioned, heels 400 and 401 are being closed at the same time that the axis of spinner 326 is moving forward. If they do not clog, the heels will reach a fully closed position before the 326 axis reaches its fully forward position (see stage 3 (a) above). But if the heels are obstructed (or where they are placed around too large a beam), or for any other reason they have not been completely closed before the spindle of the spinner 326 has reached its fully forward position, it is advantageous not to hold the 406 spinner retainer hub in place. This is because the operator wants to invert the tool and reposition the spinner's beads and spindle to the initial configuration (open heels, retracted spinner) - leaving the spinner shaft unclamped in the event that the heels are not have closed, will allow the operator to more easily reverse the tool (as will be explained later) and re-establish it to the initial configuration. To prevent the spindle of the spinner 326 from locking and holding in its fully forward position, when the beads have not been closed, the inhibiting lever 414 is loaded with the spring in the counterclockwise direction and engages the 408 detent arm, preventing it from falling more than enough to acerrojair. However, if the heels 400 and 401 have been previously closed (or sequentially), the cam feature 423 of the cam plate 422 on the push rod 390 of the bead will have moved forward enough to push the cam bolt. 418 of the lever which inhibits the fastening or bolt, which in turn rotates the lever 414 which inhibits the bolt in the clockwise direction, allowing the detent arm 408 to fall fully and be locked and clamped by bolt pin 412 engaging bolt 409 in detent hub 406. 3 (c). Releasing the Wire Impeller (and holding the spinner head). In this third phase of the operation, the beads 400 and 401 are closing (see step 3 (a) above), and the axis of the spinner 326 is moving to the fully forward position (see step 3 (b) above) . Although both of the heel impeller and the spinner impeller are moving simultaneously, the heels will close first and then the spinner shaft will reach its forward position and clamped. At this point, it is time to release the wire impeller (which was fastened in the initial configuration, see stage 1 above). When heels 400 and 401 close normally (before the spindle of the spinner 326 is fully forward), the push rod of the heel 390 will have advanced to its fully forward position. Accordingly, the cam of the lever 354 which inhibits the release of the pin of the wire mounted on the push rod 390 of the bead will lift the lever cam bolt 350 which inhibits the release of the wire fastener. The movement of the release pin 350 rotates the lever 348 which inhibits the release of the wire pin, in doing so it no longer prevents the ratchet 344 of the wire clamp from being lifted away from the wire clamping wheel 342. See FIGURE 26B. This fulfills one of the two conditions for releasing the wire impeller (ie, the beads are closed) and allows the wire impeller to be unclamped when the second of the two conditions is met (i.e., when the axis of the spinner 326 subsequently reaches its fully forward position). Now the discussion continues with the assumption that the heels have closed. As the spinner shaft 326 reaches its fully forward position * and the detent hub 406 is held in place, the driving thread of the spinner 330 will have moved to its fully forward position. Accordingly, the latch release tab of the closure 352, which is integral to the driving thread of the spinner 330, will have been lifted by the latch release lever 346. As a result, the lever 346 for releasing the wire closure pushes on a spring, which actuates the ratchet 344 for closing the wire by decoupling it from the closing wheel of the wire 342. See FIGURE 26C. At this point, each of the two conditions has been met (ie, the heels are closed and the spinner shaft is in its fully forward position) and the wire driver is unclamped. The wire tie tool of this invention is also designed to take into account the possibility that heels 400 and 401 should not be completely closed (because they have encountered an obstruction or the joint to be tied is too large) when the The spinner shaft 326 reaches its fully forward position and the release tab 352 of the wire fastener drives the wire fastener release lever 346. In this case, the second of the two conditions for releasing the wire impeller (ie, the spinner impeller is forward) will have occurred, but the first condition will have failed (ie, the heels were not completely closed). If this is the case, the ratchet 344 for closing the wire is inhibited from movement by the lever which inhibits the release of the wire holder 348 and this will prevent premature loosening of the wire driver. This is done by a spring that loads the lever 348 which inhibits the clamping release of the wire in the inhibiting position, where it engages the wire locking ratchet 344 to prevent its lifting from the wire clamping wheel 342. In this case ,, the power can not be transmitted to the spinner impeller or the wire impeller and will be released through the main overload clutch 314. Because the wire impeller remains clamped, the wire will not be fed and the tool operator will be able to uncouple and re-establish. The discussion will be summarized under the assumption that the heels have been closed, the spinner shaft * is forward and the wire impeller is therefore loose. 3 (d) Intermediate configuration (closed heels, spinner shaft forward, wire impeller unclamped). At this point, with the heel impeller, having closed the heels and with the impeller of the spinner having driven and fastened the spinner shaft in its fully forward position, the tool that ties the wire is in an intermediate configuration. The heels are now closed, the spindle shaft is now forward and clamped, and now the wire impeller is unclamped. 4 - Power for the Wire Impeller (which forms and pulls the loop). In the operation sequence, the fourth stage activates the wire impeller in two directions to form the loop and then pull back on it. In the first direction, the wire is driven through the pulley, through the first opening in the head of the spinner, around the heels and out through the second opening in the spinner head. 4 ( ) . Feed Phase of the Wire Drive (forming the loop). Since the spindle 326 of the spinner is fully forward and the spinner retainer hub 406 is held in place (see step 3 above), the differential case 320 can no longer rotate. The power, previously directed to the bead impeller and the spinner impeller (see step 3 above) must now be directed to the differential output shaft 340 to drive the wire impeller. Even if this happens, the power is still being supplied to the front bead bolt 386 of the bead driver, but the impeller is immobilized and the power is released through the bead overload clutch 384.

Now with the wire driver unclamped, the power is transferred through the differential output shaft 340, the wire clamping wheel 342 passes to the conical bevel gear 356 of the wire impeller, which drives the bevel gear 358 that drives to the wire impeller. The conical bevel gear 358 directly drives the overload clutch 360 of the wire impeller. From the overload clutch 360 of the wire impeller, the power is transmitted to the pulley drive shaft 362, which directly drives the drive pinion of the pulley 366. The drive pinion 366 of the pulley drives the pulley planetary gear 368, which directly drives the pulley cylinder 370 and drives the roller gears 374 of the pulley, which directly drive the rollers 372 of the pulley. The wire is pulled from the winder 600 and enters the pulley 364 through the inlet feed guide tunnel 376, as it passes through the inlet feed guide 378. Then the wire is fed into the left slot of the feed. first pulley roll 502, where it is held against the pulley cylinder 370 to provide driving force. The wire is guided to the groove in the second pulley roller 504 with a slight shift to the right, again clamped against the pulley cylinder 370 to be added to the driving force. The wire continues the entire path around the pulley cylinder 370 passing 10 rollers 372, each having a slight shift to the right until it reaches the right slot in the original roller 502 (this being the only roller having two slots) and which passes inside the outward feed guide 380 where the pulley 364 leaves inside the feed tube 382. From the feed tube 382, the wire then passes through the opening in the upper side of the head of the spinner 332 , around the channel in the heels 400 and 401 back through the opening in the lower side of the head of the spinner 332, exactly as discussed previously in relation to the first embodiment and, for example, FIG. 11. refers to this previous discussion for the details. The wire is fed a short distance away from the bottom of the spinner head, until it makes contact with the oscillating connection 336 of the wire detector. The oscillating connection 336 rotates by being in contact with the wire and the oscillating connection will find and activate the wire detector 338. (b) Phase of Pull back of the Wire Drive (pulling the loop). When the wire is looped through the head of the spinner 332, heels 400 and 401 and the end of the wire has hit the oscillating connection 336 of the detector, it is time to pull back on the loop. The wire detector 338 is a proximity switch, activated by the oscillating connection 336 of the detector. A signal from the wire detector 338 to the reversible motor 300 stops and reverses the motor 300. Because the spinner head is clamped (see step 3 above), the inverted motor will activate the bead impeller and the wire impeller , but not to the spinner driver. Immediately by inversion, the beads 400 and 401 start to open and the pulley 364 starts pulling the wire back. As the wire pulls back and the heels begin to open, trap doors 404 open, allowing the wire to escape from heels 400 and 401 as the loop is being tightened around the bundle of rods. Since the wire is tightened around the rods, the tongue of the oscillating connection 337 of the wire detector is raised to hold the end of the wire.

This mechanism works to prepare the tool for the stage of forming the knot under any of the various circumstances. If, for example, a small beam of rods is going to be tied, the heels will open completely before the wire is pulled back completely by the pulley 364. If, on the contrary, a large bundle of rods is to be tied, the pulley 364 will squeeze the wire before the heels 400 and 401 are totally open. In this case, the wire drive overload clutch 360 will keep the wire tight and release the torque by using a detent action until the heels reach their fully open position and the knot formation stage begins. If, finally, the heels are prevented from fully abateting for any reason, the 364 pulley will pull the wire tight and the 360 wire overload clutch will keep the wire tight and will release the torque through the retainer until the heels are left open completely. 4 (c) Separation of the spinner head (and resumption of the wire impeller). In this fourth phase of operation, the heels are covering and the wire impeller is pulling back. When the heels 400 and 401 are fully open and the wire is pulled, tied, it is time to separate the head from the spinner 332, so that the operation forming the knot can begin. When the heels 400 and 401 are fully open, the push rod 390 of the heel will have retracted to its fully retracted position. Accordingly, the cam feature 425 of the cam plate 422, mounted on the push rod of the bead 390, will have activated the cam bolt 420 of the finger that releases the pin, by rotating and lifting the finger releasing the bolt 416 The finger 416 is a pivot finger which releases the detent latch 412, such that the catch bucket of the spinner 406 can rotate away from the latch roller 410. It will be recalled, that in step 3 (b) above, the retainer roller 410 has fallen behind the lobe hub of the spinner 406, holding the spinner shaft 326 in position - of the detent arm 408, was held down by the engagement of the bolt 409 on the detent hub 406 with the latch bolt 412. Now, when the latch bolt 412 is released, it will return to its position without locking. This allows the detent arm 408 to be lifted, thereby releasing the spindle of the spinner 326. Since the pulley 324 pulls back on the wire, the tightening of the loop around the beam of the rods to be adapted, sufficient torque is transmitted to the spinner shaft 326 through the differential 318 to rotate the spinner retainer hub 406 in the clockwise direction. "Sufficient torque" is a pre-set value, which is adjusted to match the desired backward traction attention (this can be either 2.27 kg or less, 68.1 kg or more, or any value between them). This raises the detent arm 408, which allows the retainer hub of the spinner 406 to rotate in the clockwise direction. As the hub 40 rotates, the release tab 352 of the wire holder rotates away from the pin release lever 346 of the wire. This allows the ratchet 344 of the wire pin to engage the pin wheel 342 of the wire, which then fastens the wire driver. See FIGURE. 26A. At this point, the heels are fully open, the wire impeller is clamped, the spinner impeller is unclamped and the motor is rotating in a clockwise direction. 5. Power for the spinner impeller (operation that forms the knot - retraction of the spinner shaft and extrusion of the knot). This point, with the open heels and the driven wire impeller, the full moment of torque is transmitted to the spindle of the spinner 326 and the spinner head 332. This provides full power for the operation of forming the knot. Since the head of the spinner 332 starts to rotate in a clockwise direction, the wire begins to flex, where the head of the spinner 332 enters and exits. The bending action ties the ends of the wire to allow the spinner head to apply tension to the ends of the wire, while the knot wire is being extruded. At the same time and as the spindle of the spinner 326 begins to rotate in a clockwise direction, the auxiliary spring 424 which was previously compressed (see step 3 (b) above) (?), it provides an additional force, which pushes on the auxiliary spring roller 407 of the catch hub of the spinner 406. As the knotting is being completed, wire cutting begins. The wire is cut, first, at the entrance of the spinner head 332 and then at the exit of the spinner head. This is a stepped cutting action which reduces the torque requirement for the spindle shaft. The cut is activated by the combined torque of the drive motor 300 and the auxiliary spring 424.

Spinning head 332 continues to rotate, completing the cut and rotating four turns. This extrudes the knot and returns the spinner shaft to its retracted position. When the axis of the spinner 326 reaches the fully retracted position, the rear limit detector 426 (a proximity switch) sends signals to the motor 300 to shut off. 6 • Reset to the Initial Configuration. When the engine 300 is turned off, the operator releases the activator. At this point, the tool is back in the initial configuration - the beads 400, 401 are open, the axis of the spinner 326 is retracted and the wire driver is in place - and the operator can move the tool to a new one Location and place the heels around the next beam of rods that will be raised. When the operator pulls the trigger, the next cycle will begin. 7 - Investment button (obstructions, jamming, storage and repair). The wire tie tool has a reverse button 608, which allows the operator to reverse the direction of the drive motor 300 at any point in the cycle. The action of the inversion button at several points in the cycle will now be explained. (a) In an initial part of the cycle (see the beginning of stage 3 (b) above), heels 400 and 401 are closing and the spinner shaft 326 is moving forward, but not yet held in place . By operating the reverse button at this point, it will open the heels and retracts the spindle of the spinner 326. (b) In an intermediate part of the cycle (see step 3 (b) above), the stubs 400 and 401 are closed, the The spinner shaft 326 is fully forward and clamped and the wire impeller is loose. The wire impeller is coupled and the wire is being fed forward through the beads. By pressing the reverse button at this point, it will open the heels and simultaneously pull the wire back. (c) Later in the cycle (see step 4 (b) above), the wire has been fed in the entire path through heels 400 and 401 and the end of the wire is detected. The motor 300 now reverses (so that it is running in the clockwise direction) and the beads start to open as the wire is being pulled back. By pressing the reverse button at this point, it will close the heels and feed the wire forward. (d) Still later in the cycle (see step 5), the wire has been pulled back moored, the beads 400 and 401 are fully open and the catch bucket 406 has been pulled free, without holding the shaft of the spinner 326. The wire is cut and the spinner is rotating and retracts as the knot rotates. Pressing the reverse button at this point will drive the spinner shaft forward and close the heels. The reverse button would be activated in the previous points in the cycle, as necessary and in circumstances such as the following: For the Remaining Wire Removal. When a wire winder has been used completely, there may be a remnant of wire left inside the wire lashing tool, which must be removed before starting a new winder. The elimination is done by activating the tool and making it advance just enough in the cycle to couple the impeller of the wire and start feeding wire in the heels. Here, the reversing button will interrupt the cycle of the wire impeller, reverse and the wire will be pulled back out of the pulley 364. Now the operator can start the new wire end of the new winder inside the pulley and can proceed with the normal operation of the tool. To Clean Heel Suction. If the heels 400 and 401 are placed around a beam too large to be fully encompassed by the heels, in such a way that the heels do not close (or if the heels are clogged for any reason and do not close), the reverse button will stop and reverse the heels. The heels will open and the spindle of the spinner 326 will retract. Now the tool is set and the operator can resume normal operation. To Clean Wire Drawings. If there is a wire draft during feeding, the operator can use the reverse button to reverse the wire feed. This usually cleans the appraisal. If the bagging is not cleaned, alternatively the operator can push the wire back and forth using activator 606 and reverse button 608 to clean the bag as necessary. When the wire gauging is removed, then the operator can start the cycle again. After the storage of the tool. Before the tool is stored, the operator will pull the trigger 606 to close the beads 400 and 401. Before reusing the tool after storage, the operator must operate the reverse button 608 to open the beads to the initial configuration. Maintenance and Repair. For maintenance and repair, the reverse button can be used as needed and together with the activator 606, to position the spinner and the heels, to test the mechanical logic, to test the various clutches and differentials and the like.

The description above explained the tool, with reference to the embodiment of FIGURES 1-12 and the embodiment of FIGURES 13-32. The various assemblies, including the heels and the spinner, to cover a joint of rods or any other object that will be tied and to form a knot by a loop of a length of wire around the object, keeping the loop under tension and then spinning and extracting the knot, have been explained. Likewise, the various impellers, including the bead impeller, the wire impeller and the spinner impeller to transmit power from a single motor to the beads, the wire pusher / squeegee mechanism and the spinner have been explained, together with A control system will stop the sequence of the various operations. The method of using the tool has been explained in the course of describing its components and its operation. It should be clear that an operator simply places the heels around the object to be tied, pulls the activator, and then pulls the tool apart, leaving a twisted knot behind. The machine can tie several knots per minute (the variables that affect the number of moorings include the thickness of the material to be moored and the distance between the moorings - under controlled conditions of thickness and proximity of a prototype of the moored device approximately 20 knots per minute). Once the concept of this invention was understood, it should be apparent that any number of variations or substitutions can be made, even within the scope of the invention. Beyond the obvious replacement of the electronic logic control devices for the mechanical logic devices already described, some other additions and variations will be briefly described in the following. Additions and Variations Among the additions and variations are these: (a) An Elongated Handle. The handle 602 as shown in FIG. 13 is near the tool itself. An elongated handle 603 is shown in FIG. 30. The elongate handle extends to the operator's reach and the support handle 604 must be moved toward the back of the tool as necessary, to facilitate extension. The use of a machine operator in certain applications (such as tying a grid of rods to the operator's feet, or tying certain objects on his head) must be greatly facilitated by the longer range, produced by the elongated handle. A trigger 606A and a reverse button 608A place the necessary controls within easy reach of the operator in the elongate handle 603. (b) Heel Modifications. It has already been explained that the bead assemblies (jaw assemblies) can help to define the wire path, which is fully closed (the embodiment of FIGURES 1-12) or partially closed (the embodiment of FIGURES 13-32). ) and that the channel enclosing the wire must be opened by means of swinging doors, trap doors or floating plates, other variations are easily understood. In addition, all that is required is a circle closure. It should be readily apparent that the pair of heels ostracted and described herein could be replaced by a single hook-shaped heel. Such individual heel could be placed on the object to be tied and then pulled back, held, or secured in any other way around the object. (c) The object that will be tied. The most obvious example of an object that will be tied with the tool of this invention, is a transverse joint of rods. The tool, however, is not limited to a single application but is appropriate for any object that is to be tied. It is also useful for any object that needs to be twisted. For example, the tool can be easily adapted for the use of forming the ties in hooks for metal clothes, in product wraps, in bag closures, in wire that is attached to fence posts and in any of almost an unlimited number of uses that imply a tie-down knot. (d) The Wire or Other Material That Forms the Knot. Although the tool of this invention is especially suitable for use with a heavy duty wire, it is not limited. Any kind of material that could be twisted could be used. Thus, the terms "wire", "wire driver" and the like, when used in this specification, or in the claims, should be understood to include not only wire but any material used to form the knot, the impeller which push or pull such material, etc. When using a wire or other material, it must be clear that certain other advantages can be specified. Among these are these: (1) the wire may be covered with a liner, coated (or treated) with a thermoplastic material bonded by melting, or treated with a "slip agent" of polyethylene, and / or (2) the wire It can be marked with one or more marks or stripes. The coating or treatment is designed to vary the tack and allows the coefficient of friction to be tightly controlled (i.e. the wire can be made more or less "slidable" by a coating or a treatment which decreases or increases the relative friction coefficient for uncoated or untreated wire). The mark may be one or more stripes (perhaps one stripe every 15.24 cm (6 inches), more or less) with strips that can be read by an optical or electromagnetic device or other detection or reading device. Among other things, such a system could be: enchaveta? Or for wires coated or treated to avoid the coating or wrong treatment (or uncoated or untreated) of the wire that is used, so that damage to the machine is avoided; keyed to count the number of marks for the use of the machine monitor and proper maintenance (or to monitor usage for loading purposes for the use of the machine, or for any other purpose.) (e) The bobbin winder. , as shown and described in the various drawings of the various embodiments shown herein, is invariably driven by a loaded spring, with clutch and driven in any other manner, such that the wire is kept under sufficient pressure to prevent its expansion in It should be readily understood that there are many equivalent mechanisms to prevent the wire from expanding in the winder.In addition, it should be understood that the winder is, or may be, removable (for reloading with wires) and / or replaceable (with reloaded reels). In these cases, the winder will be specially keyed to the tool in such a way that it will be attached and fastened in place. Suitable actuators can be used to detect when the winder is properly held in place, so that the operation can not proceed without a suitable winder held in place. In this way, together with the coated or treated wire and / or the use of marked wire, the keying system can be important to avoid the use of standard windings and / or to avoid the use of windings without loading with the coated wire, treated or properly marked, so it avoids the improper use of the machine. In this way, it may be important that the winder of this invention is not a standard or general design winder, but that the winder is specially keyed and / or dimensioned to avoid misuse. Further, it is understood that the winder must be moved away from the tool (to a remote location, including an operator belt, a backpack or other fastener, and including a place removed from both of the tool, and the operator, such as a working rod configuration, in any case with the appropriate feeding channels). A wire can be fed, for example from a top feed channel, directly to the tool in a properly designed work station. Such work stations are well known in construction trades and will not be described further here. (f) Independent Features. The features of this invention are best developed in combination, but there is no need for all of them to always be used in joints in any particular application. Although it is generally an advantage to have a single reversible motor driving all three of the wire impeller, bead impeller and spinner impeller, it can easily be appreciated that there may be circumstances and applications in which there is a separate motor for each impeller or for any combination of the two impellers. There may also be applications, which require a "front" engine and a separate "reverse" engine. Finally, the conceptually separate stages of the feed wire and traction wire; open and close heels; and turning and retracting (and then turning and advancing to the starting position) have been convenient to discuss three corresponding impellers (wire drive, heel impeller and spinner impeller) and mechanisms (pulley or other feed system, bead, spinner and associated parts) as if they were three completely separate accessories. Although in the preferred embodiment, there is some physical separation between the wire impeller, the bead impeller, the spinner impeller and its related mechanisms, there is nothing to prevent them from being combined into integrated units. It should be readily understood, therefore, that it is not essential for this invention that there be any given number of discrete impellers, or that all three of the particularly mentioned impellers are present. This invention is designed to be used with all three impellers that work together as described in relation to the preferred embodiments, but does not mean that it is limited to the complete combination for all purposes.
