To all whom it may concern Be it known that I, EDMUND E. BROWN, citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented certain new and useful Improvements in VVire-Fence Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention has reference to a machine for the manufacture of wire fence and is particularly adapted for making a wire fence having a square mesh, and composed of longitudinal or line wires and a series of stay wires or pickets. The machine here shown being adapted to produce a fence having a graduated mesh, but this is not material as it may be made to produce a uniform mesh.
The stay wires or pickets are short sectional stays corresponding to the number of spaces between the longitudinal or line wires and such spaces are spanned by the sections of stays and the adjacent ends of each section coinciding with the same longitudinal wire are locked and coiled upon such longitudinal wires, the sections of stay when joined with adjacent longitudinal wires having the appearance of a continuous stay from sclvage wire to selvage wire.
The invention has for its object a series of vibratory hoppers or stay receptaclesand a series of revolubly carried disks or stay carriers which are adapted to receive succes-' sively short sections of stay and feed them to means for intertwisting or coiling them around the longitudinal wires.
The invention has for its further object a series of vibratory hoppers disposed in two rows, alternate hoppers being in the opposite row, revolubly carried disks for receiving stay sections from said hoppers and revolubly carried knotter plates adapted to receive the ends of the stay sections for coiling them around the longitudinal or strand wires.
A further object of the invention is a series of vibratory hoppers; a series of feeding disks co -acting with the hoppers and adapted to receive short sections of stays and deposit them upon means where the opposite ends of such stay sections are bent at right angles to their length; and revolubly Specification of Letters Patent.

Fig. 33 shows a style of fence made on this machine.
In the drawings, like numerals of refer ence indicate corresponding parts throughout the figures.
The machine consists of a bed composed of the side frames which support the general working parts of the machine, including the wire feeding and wrapping devices. At a suitable point in the frame, 1, there is journaled transversely, the power shaft 2 carrying on one end, a freely revolving power pulley 3 around which travels a belt 4-, adapted to be driven from any convenient source of power, not shown. The pulley 3, is adapted to be made secure to its shaft 2 through the clutch 5 operated by a hand lever 6, situated on the opposite side of the machine and attached to the vertical shaft 7, journaled in suitable bearings and its lower end connected with the crank 8 and the rod 9, the latter having connection with the clutch previously referred to. These devices are clearly seen in Figs. 1, 2 and 3.
l0 denotes a main driving shaft and owing to its reduced speed and the amount of pressure required to drive it, for reasons in practice, is operatively connected with the power shaft 2 through compound gearing, of which 11 is a pinion secured to the power shaft and intermeshes with a gear wheel 12 keyed to an intermediate shaft 13, which shaft is properly journaled in bearings supported 011 the bed frame and also carries the pinion 14 which intermeshes with a gear wheel 15 on the main driving shaft 10 for the purpose of transmitting power thereto. The shaft 10 is journaled in suitable bearings on the bed frame and carries cams, cran (S, a segment gear, and a main sprocket gear, the location and uses of which will be hereinafter fully described.
16 denotes a secondary driving shaft suitably positioned in the bed frame and receives its power from the main driving shaft 10 through a sprocket wheel 17 on the shaft 15 connected by a sprocket chain 18 with a sprocket gear 19 on the shaft 16. The sprockets 17 and 19 are of equal size, therefore the shafts 10 and 16 rotate in unison. The shaft 16 like the shaft 10 also carries a number of cams and a segment gear, the
purposes and location of which will be further described. On the opposite end of the shaft 16 is carried a sprocket pinion 20 which transmits motion to a shaft 21 for operating suitable feeding devices, through a pinion 22 engaging a sprocket pinion 23 carrier on one end of the shaft 21. Upon the opposite end of the shaft 21 is carried a sprocket pinion 24 which transmits motion to a short shaft or stud 25 by means of a sprocket chain 26 traveling around the pinion 24 and a pinion 27 carried on the stud; and by means of the stud and suitable devices carried thereby, motion is imparted to a transverse shaft 28, the same adapted to actuate suitable revoluble disks which form a part of the feed to be hereinafter described.
Having described the power shaft together with the mode of driving it, the main driving shaft and secondary shafts which control the operation of the stay section feed devices, I will now describe the manner of feeding in the strand wires and follow up such description with the operation of the feeding devices and the manner of coiling the ends of the stay sections around the strands, and the further process of crimping the strand wires and reeling the completed fabric.
At the forward end of the machine, is a series of independently arranged tension devices for holding each one of the strand and selvage wires; such tension devices consisting of two grooved rollers 29 and 30 be tween which the strand wires are drawn. The roller is revolubly carried in a stationary frame 31 and the roller 29 is revolubly carried in a frame part 32 hinged at 33 to an extension of the frame 31 which is'for the purpose of adjusting the roller 29and to facilitate in its removal for the insertion of a strand wire between the two rollers;
To cause the roller 30 to revolve with the movement of the strand wire and to prevent any slipping, the roller 29 is compressed against or caused to impinge the roller 29 by means of a spring 34 which is carried around a threaded stem 35, one end of which is attached to the free end of the frame part 32 and the opposite end passes through a U frame or yoke 36 which is detachably connected at its lower portions with the frame 31; and 37 is a thumb nut engaging the outer end of the stem 35, which is kept loose, but which when tightened against the U frame or yoke 36, assumes all the pressure of the spring and affords an easy removal of the pin which holds the U frame or yoke so that the swinging frame 32 carrying the roller 29 may be swung out of position as shown in Fig. 6. The object of such a tension device, is to offer resistance to the passage of the wires through the machine, and forthis purpose, a brake is applied to the roller 30 and consists of a brake shoe 38 which is held against the roller 30 by means of a spring 39 seated in the frame 31. The brake shoe is retained in its rela tive position with the roller in the frame by means of top and bottom flanges 40 which project slightly over the frame 31, as shown in the Fig. 6. These tension devices are all mounted in a row on a sill 42 supported by the main frame and are positioned to suit the space between the strand wires. Only one of the tension devices has been described, but as they are all similar, the description of one, will it is thought suffice for all. and feeding devices is an equalizing drum 43 which is secured to a transverse shaft 44 journaled in the frame 1, and around which each strand and selvage travels once, serving to equalize the feeding of the strand wires through the machine. The shaft and drum are operated only by the action of the drawing in of the strand wires, which is accomplished by means of the reeling devices which wind up the completed fabric to be further described.
To ascertain the length of the strand wires fed to the machine and consequently the length of the finishing product, a registering device is attached to and is operated by the shaft 44 to which the drum 43 is at tached. This registering device is repre sented by the numerals 8, 9 and 10 and consists of a pinion 45 attached to one end of the shaft 44 and meshing with a gear 46 on a short shaft 47 journaled in a bracket 49 support-edby the main frame 1. The proportionate sizes of the pinion 45 and the gear 46 are such that the gear 46 makes one revolution while the strand wires advance one rod. The outer face of the gear 46 is provided with a scale and graduated to represent feet, being read with the aid of a pointer 50. On the short shaft 47 back of the gear 46 is carried a pinion 51, meshing with a gear carried by a short shaft or spindle 53, which also carries a small pinion 54 meshing with a registering gear wheel 55 forming a part of a hollow spindle 56. The pinions and gear wheels of the registering device being of such proportion that the gear 55 makes one revolution while the winding reel, to be described, is being filled. To the gear 55, is attached a dial 57 which. is seated in the recess in the face of the gear 55 and is provided with a stem which is carried in the hollow spindle 56 of the gear 55.
In addition to the devices for registering the length of the fabric, there is provided an alarm which may be adjusted so as to automatically signal the operator when any desired amount of fabric may have been made, however, the capacity be- Coiiperating with the tension' ing that of the winding reel to be described. The alarm consists of a disk or cam 58 car ried on the end of the spindle 56' opposite to the end which carries the gear and the same is provided with a notch 59 in its periphery into which a pawl 60 drops when the notch 59 is brought co-incident with the pawl by the revolution of the disk. A lever 61 is pivotally connected to the pawl and by means of a spring 62, the lever is retained in such a position as to hold the pawl against the peripheral edge of the disk 58 and to the end of the lever 61 is attached a string 68 connected at its opposite end with any suitable alarm, so that when the pawl 60 drops into the notch of the disk 58, the movement of the lever will pull the cord 63 and strikes the alarm. The disk 58 may be adjusted in any suitable position relative to the gear 55 by the lock nut 64: which has a threaded connection with the end of the spindle of the gear 55; the adjustment being made according to the graduations which represent rods on the dial 56, compared with the pointer 6 a coacting therewith.
The strand wires are fed into the machine from the winding drum 43 through guide tubes 64: carried by suitable brackets supported by the main frame. They are further directed by guides at various points throughout the machine, but these will be described in conjunction with other feeding and guiding devices.
The stay feeding mechanism for applying the sections of the stay to the strand wires, consists of a series of vibratory hoppers 65, the same being supported in rows above the path of the strand wires and in the same are deposited short sections of stay in length to compare with the spaces between the strand wires to which they are fed. The succeeding sections of a stay, the adjacent ends of which are adapted to be coiled around a coinciding strand are fed from hoppers alternately disposed in opposite rows. The bottoms of the hopper 65 are provided with slots or wire grooves 66 which communicate with vertically disposed slots or grooves 67 and the slots 67 at the lower ends communicate with revolubly arranged disks 68 carried upon the shaft 28 and 70; the peripheral edge of the disks 68 being provided with the notches 71.
To insure a deposit of the stay sect-ions into the slots 67 as was intimated the walls of the hoppers 65 are caused to be vibrated which keeps the stay sections in constant agitation and drops them one by one into the slot 67, following each other successively as fast as they are removed from the slot (37 by means of the disks G8, the stay sections depositing themselves in the notches 71 of two or more disks and by the revolving of said disks, they are fed farther into the machine. The arrangement of the hoppers is best seen in plan in Fig. 2 and in section in Figs. 11 and 12. The side walls of the hoppers 65 are provided with the lateral extended flanges 72 by means of which they are held in place by gibs 73 into which the flanges are dove-tailed and in such a manner as to adapt the walls of the hoppers to have longitudinal movement.
The mechanism for vibrating the hoppers 65 consists of the links 74; suitably connected with the sides of the hopper and with a bell crank lever 75 which is fulcrumed at 76 to a bracket 77, and to the bell c'ank lever is connected a rod 7 S which at its lower end is connected with a strap 7.) which is ecceir trically connected with the power shaft See Fig. 11 for the connection of the rod 78 with the bell crank lever and the hopper, and Figs. 3 and 4 for the connection of the rod 78 with the eccentrically connected strap 79.
The bottom of the hoppers is indicated as 80 disposed transversely across the machine and also serves as a support for various guides, brackets, etc. The slots (37 referred to which lead from the bottoms of the hopper, are made by the arrangement of guide plates 81 and 82 attached to and depending from the base of the hoppers and suit-ably spaced to provide the slot or groove 67. 7 Referring to the disks (58 which are so positioned as to receive the stay sections from the slots 67, the shafts to which they are attached are journaled in the guides 81 and are adapted to be intermittently and simultaneously revolved in opposite directions and upon coinciding ends of the shaft 29 and 70 re provided with the intermeshing gears 83 and 84s; the shaft 28 extending out through the frame supports 1 and is driven through gearing from the shaft 2i in a n1anner and for a purpose to be described.
As the feeding disks G8 are revolved with the stay sections which are seated in the notches thereof, the said stay sections are carried forward by the revolution of the disks to a point in line with forming plates 85 suitably supported on the guides 82 and are made of harder material than the guides supporting them and are used to avoid excessive wear, it being more convenient to replace a forming plate than one of the guides. The disks are intermittently stopped and held stationery for a pre-determined period at which time, means is actuated for bending the opposite ends of the stay sections at right angles to their length. The guide plates 82 to which the forming plates are attached, have portions 86 which overlie a portion of the peripheral edges of the disks and serve to retain the stay sections on the disks during their movement under this portion of the guide plates and also to prevent their becoming dislodged during the formmg process.
The mode of forming or bending the stays, for purposes to be hereinafter described, is by means of a series of plungers indicated as 87, the same being arranged in pairs upon the outside guide plates 81 and 82, and are carried by angle bars 88 which extend transversely across the machine bed and upon the opposite ends, support or have attached thereto the rack bars 89. The plungers are provided with the reduced stems 90 which project loosely through perforations or slotted openings in the upright portion of the angle frames 88 and are held relative to longitudinal movement with the angle frames by means of cotter pins 91, see Fig. 13. The means for moving the rack bars and thereby moving the plungers which are attached to the angle bars 88 which support the racks, is by means of the segmental gears 92 which are carried upon shafts 93 and adapted through the operation of the shafts 93 to intermittently project the plungers 87 and return them to their normal positions; the shafts have attached thereto the short levers 91 and the said levers are connected to the rods or bars 95 and 96 which at their outer free ends have yoke portions 97 carried by the shaft 21. The rods or bars 95 and 96 are each provided with rollers 98 adapted to be engaged by cams 99 which are carried by the shaft 21.
From an examination of Figs. 11 and 13, it will be seen that by reason of the alternate disposition of the hoppers, the plungers are placed so that each alternate pair moves in opposite directions or toward each other, thus the opposing rack bars with which the plungers are attached must be moved in opposite directions, and to accomplish this, the arrangement of the cams 99 on the shaft 21 and the disposition of the rollers on the rods or bars 95 and 96 must be such that during the continued rotation of the shaft 21, the segmental gears 92 will be oscillated in opposite directions and thereby advance each alternate pair of plungers toward each other.
In the reciprocation of the plungers 87 the ends thereof will engage with the stay sec tions at or near the opposite ends and bend them forward against the forming plates 85. The disks which sup-port the stay sections and the curved portions of the guides 82, serve to hold the body of the stay sections and prevent their bending, there being also provided, an intermediate series of disks 08 which will prevent the body of the stay sections from bending or buckling during the operation of bending the ends thereof. To insure that as the stay sections are bent, the ends thereof will be bent forward and lie against the forming plates and the guides, the plungers being arranged to be reciprocated and at the same time have imparted to them, a circular or an oscillatory movement, and for this purpose, each of the plungers is provided with the inclined or cam faces 100 which in their movement, ride against rollers 101 pivoted to the plates 102, see Figs. 11 and 13 and in Fig. 13 a pair of plungers are shown in dotted lines in their released position, the remainder of the figure showing the plungers projected and the stay sections with their ends bent against the forming plates. In operating the segment gears and the racks the cams 99 operate against springs 108 which assist in returning the racks and plungers to their normal or released position. There are also provided springs 10 1 the opposite ends of which connect the shanks or extensions of a pair of plungers and are adapted to draw the shanks or extensions toward each other as shown in dotted lines in Fig. 13 which separate the forward ends of the plungers and place them in the position to engage the extreme opposite ends of the stay sections to insure the proper bending thereof.
Referring to the plates 102 which have been described as extending transversely across the frames and to which the rollers 101 are attached; the same are supported by brackets 105 which in turn are supported by extensions of the hopper gibs 73, and the brackets 105 are recessed as at 106, see Fig. 12, to receive the opposite ends of the plungers carrying frame 88 and serve as guides therefor.
To intermittently actuate the shaft 28 for imparting a corresponding movement to the feed disks 68 carried thereby and those upon the shaft 70, I provide on the outer end of the shaft 28, a wheel 107 which is intermittent-1y revolved by means carried on the shaft 25 which is driven from the shaft 21. the last mentioned shaft receiving its power from the shaft 16 and it from the power shaft in the manner previously described. In one of the faces of the gear 107 is provided a series of radial slots or grooves 108 extending from a point in the body of the gear to the peripheral edge thereof. On the shaft 25 is carried a short crank or arm 109 and upon its outer free end is journaled a roller 110, and it is adapted that as the shaft 25 and the arm 109 is revolved, the roller 110 thereof will intermittently and successively engage with the slots or grooves 108 of the gear 107 and causes the wheel 107 to advance the distance of the space between a slot which is suflicient to rotate the shafts 28 and 70 a sufficient distance to carry the feed disks forward to place the stays which are seated in the notchesthereof in a position to have their ends bent at right angles in the manner described. To look the position of the shaft 28 and the gear 107 carried thereby while the shaft 25 is making a partial rotation to bring the roller 110 to enter a succeeding slot of the gear, I provide the back of the gear with a series of semi-circular grooves or pockets 111 which are struck on an arc of a circle whose center is the center of the shaft 25 and into which is adapted to be seated and revolved, a segment roller 112 which is attached to and revolved with the shaft 25, the circular face of the roller operating in the pockets 111 simultaneous with the moving away of the roller 110 from the grooves 108. The notches 71 of the feeding disks 68 are so positioned relative to the arrangement of the grooves 108 on the gear 107, that when the roller 110 leaves the gear 107 and the shaft 28 is caused to stop, the notches of the feeding disks 68 which are feeding forwardly a stay section will be in line with the center of the forming plates 85 and the plungers 87, remaining in such a position a suflicient length of time for the process of bending or forming the stay sections, and as the shafts which carry the feeding disks are again partially rotated, the feeding disks Will carry the then bent stay beyond or below the end of the guide plates 82, when the stay section by gravity will drop on to reciprocally supported collecting fingers 113, which said fingers subsequently pass the stay sections to the strand wires around which the ends thereof are coiled.
The collecting fingers 113 are disposed beneath the feeding disks 68, there being a pair of such fingers to co-incide with the stay sections fed by the opposite and alternately .disposed feeding hoppers, and the said fingers are rigidly attached to and carried by transversely arranged bars 114, the opposite bars being operated through connections with shafts 115 and 116; the said shafts carrying cams 117 which operate against rollers 118 carried by yoke arms 119, the yokes adapted to reciprocate across the axis of the shafts 115 and 116 and are connected to the bars 114 by blocks 120 through the stems 121, the yoke arms responding to the action of the cams by means of springs 122 attached to the opposite end of the bars 114 and to suitable frame parts, the springs shown attached to the bars 114 in Fig. 14. The collecting fingers 113 passed through guides 122 which are suitably attached to the guides 81.
To advance the stay sections to their coiling position on the strand wires, I have provided the compression shoes 123 which are of suitable length and disposed vertically in the machine adapted to act upon the formed ends of the stay sections and have broad enough faces to insure a proper contact with the formed ends of the stay sections. The forward movement of the compression shoes will bring the formed ends of the stays against blocks 124. which are attached to a.
swingably supported backing plate 125, the collecting fingers as will be seen in the drawings, pass through the compression shoes and have movement there through and simultaneously therewith. The col'npression shoes 123 and the blocks 124 serve as jaws bet-ween which the ends of the stay sections are firmly held, leaving a slight space between the body of the stay section and the backing plate 125 for a purpose to be described. The coml'n'ession shoes 123 are attached to rods 126 and the said rods are loosely carried through a carrier frame 127, nuts 128 engaging the ends of the rods 126 to connect them with the carrier frame, and 129 denotes coiled springs which are carried on the rods 126 and bear between the matching faces of the compression shoes and the carrier frame and serve as a cushion between the said shoes and the carrier. The com pression shoes 123 and the carrier frame 127 through their connection therewith, are operated by cams 130, see Fig. 14, which are secured to the shafts 115 and 116 which act upon the yoke stems 131, the latter pass ing through guides 132 supported by the previously described guides 80, the yokes being held to the action of the cams by springs 134 carried on the yoke rods .131 in the manner shown in Fig. 14.
The backing plate 125 to which reference has been made, in its normal position, lies in the path of the formed ends of the stay sections as they are deposited on the collecting fingers 113 by means of the feeding disks 68, and to avoid an interference of the ends of the stay sections with the backing plate as the said stay sections are lowered, the backing plate 125 is caused to drop a sufiicient distance to permit the formed ends of the stay sections to pass the backing plate, because of the fact, that as the stay sections are lowered, after their ends have been bent the ends will swing dmvnwardly in an arc of a circle by reason of gravity from a horizontal to a vertical position, the body of the stay sections remaining in a horizontal position. Fig. 13 shows the stays just after forming and previous to dropping and in Fig. 12 the formed ends of the stay sections are shown projecting doi'vnwardly with the backing plate in its normal position after being lowered andsubsequently raised. The backing plate is retained in its normal position by means of the supporting rods 133 which are connected with the opposite ends thereof and the said rods pass up through the base plate and have a collar 134 attached to their upper ends between which and the plate 80 are carried springs 135 which return and. retain the backing plate 125 in its normal position after lowering. The means for lowering the plate, consist of the levers 1.36
fulcrumed at 137 to brackets 138 supported from the lower face of the plates 102. The free ends of the levers 136 he upon and are adapted to be intermittently raised by cams 139 which said cams are attached to the shaft 115. Thus it will be seen, that during the continued rotation of the shaft 115, the cams 139 will cause the oscillation of the levers 136 and cause the dropping of the backing plate 125, the same being raised to its normal position through the action of the spring 135 as the irregular face of the cam moves away from beneath the lever 136. The manner of driving the shaft 115 is through a sprocket chain connection 140 with the previously described shaft 21. which connects with a sprocket 141 thereon and with a sprocket 142 on the shaft 115, see Figs. 11 and 14; and the shaft 116 is driven in unison with the shaft 115 by means of a chain 143 connecting a sprocket 144 on shaft 116 with a sprocket 145 on the shaft 115. The shafts 115 and 116 arejournaled in bearings 146 which are supported on the lower face of the plates 102, see Fig. 11.
In the further delivery of the stay sections as they are advanced to the strand wires around which they are coiled, 1 cmploy a series of delivering forks 147 which are adapted to have vertical movement and move the stay sections from between the compression shoes 123 and the blocks 124. The lower portion of the delivering forks have the bifurcated extensions 148 which lie adjacent to the backing plate 125, somewhat in the manner as shown in Fig. 12. To the faces of the extensions 148 which move adjacent to the stay sections, is attached the fiat springs 149, see Fig. 18; the upper ends only thereof being connected, the lower ends curved outwardly as shown and at a point about the center of the spring there is provided a stop pin 150 secured to the extension of the fork and projecting loosely through an opening in the spring. When the delivery forks are in their eX- treme raised or normal position, the springs 150 are disposed slightly above the stay sections, and as the forks are lowered, by means to be described, the stay section is wedged between the fork extensions and the springs. The forks are extended until the stay sections abut with the pins 150 in which position they are are wedged between the extensions of the forks and the springs, the latter holding them against such extensions, and the means for actuating the forks is so arranged that as soon as the sections are caught up by the said forks, the latter are slightly raised to permit the compression shoes and the collecting finger to recede, the raising of the forks relieving any pressure of the sections against the compression shoes and the collecting fingers and as soon as the said collecting fingers and compression shoes recede, the delivering forks are again continued in their downward movement to deposit the stay sections on the strand wires at a point between a suitable knotter or twister plate to be described. The shanks or upper portions of the delivering forks 147 extend up through the plate 80 and their extreme upper ends are attached to a transverse bar, the opposite ends of the bar being provided with rollers 152 which operate in vertical guides 153 and also in slots 154 of levers 155. The guides 1.53 are supported by the gibs 73; and on one end of the gib 73 is secured a bracket or arm 156 to which the lever 155 is pivoted at 157, and to the lower end of the lever 155 is attached a spring 158 which at its opposite end is suitably secured to some frame part and draws the lever in an upward position and the delivering forks also, the said spring yielding to the actions of a cam 159 secured to the shaft 21 which operates at pre-determined intervals to lower the delivering forks, by engagement with a roller 160 attached to the lever, see Fig. 11. The irregular portions of the cams 159 are such that during the lowering of the forks at the time when they receive the stay sections, will cause the said forks to raise slightly and be again lowered for the purposes above stated.
As the delivering forks 147 are raised from their lower position, the stay sections are drawn from beneath spring plates 149 and the extension of said forks are retained in the position in which they are placed upon the lowering of the forks, as the latter are raised to their upper normal position, which is accomplished by means of the reciprocally arranged gripping fingers 161, see Figs. 19 and 20 which are adapted to be advanced and the forward ends thereof carried over the body of the stay sections and hold them in their place on the strand wires while the forks which lower them to this position, are being raised. These gripping fingers operate through a suitable housing 162 which serves as a guide for the fingers and at 163 the fingers are off-set or bent out of line in order that a bar 164 to which the rear ends are attached and which serves as a carrier therefor, may lie out of the path of the strand wires. The opposite ends of the carrier bar 164 are pivotally attached to levers 165 which are fulcrumed at 166 to a suitable bracket 167 in the bed frame. The lower ends of the levers 165 have a pivotal connection with ayoke rod 168, the yoke of which is movable across the axis of the shaft 16, and movement is imparted to the yoke rod 168 by means of a cam 169 carried by the shaft 16 which operates against a roller 170 carried by the yoke rod for the purpose of reciprocating. said rod and through the lever connection with the carrier bar 164: reciprocate and extend the gripping fingers 161; the gripping fingers being extended as shown in Figs. 19 and 20. There is provided springs 171 attached to a suitable frame part and to the upper end of the lever 165 for yieldingly holding the roller 170 against the cam 169.
The knotter plates or coiling disks which coil the formed ends of the stay sections around the strand wires, are best seen in Figs. 21, 22, 23, 24, 25, 26 and 27. In the feeding of the strand wires they are carried through the center of the knotter plates or coiling disks, and the stay wires as they are lowered by the delivering forks, they will be deposited with their bent portions overhanging adjacent strand wires somewhat as shown in Fig. 24.
The coiling disks for coiling the ends of the stay sections'around the intermediate strand wires are constructed slightly different from the disks which coil the outer end of the upper and lower stay sections around the selvage wires. The coiling disks for the stays of the intermediate strand wires, are arranged in pairs and will be referred to as knotter plates 172 and 173 which are brought adjacent to each other and interlock the co-inciding ends of the opposite stay sections and coil their ends in opposite directions around a strand wire.
The disks which co-incide with the selvage strands, will be indicated as 174 and 175 and will be referred to as a coiling and a seating plate; the disk 17 1 adapted to have seated in a groove therein through the action of the disk 17 5 one end of a stay section which will be coiled around the selvage strand, there being only one section of a stay, there is no need of a coiling disk such as employed with the intermediate strand wires, there being no necessity for interlocking the end of the stay section. See Fig. 33 in which a view of the fabric is shown and the form and manner in which the stay sections are coiled around the intermediate and selvage strand wires. In Figs. 24 to 27, is shown the manner of carrying the stay sections in the twister and knotter plates and the manner in which they are coiled around the strand wires. For con venience, the selvage wires will be indicated as A, the intermediate strand wires as B, the stay sections as C, and the formed ends D which are coiled around the intermediate strand or selvage wires.
The selvage twisting plates 17 1 are provided with a lug 176, which, during the revolution of the twister plates engages the ends D of the stay sections and directs them around the selvage wires A. The face of the lug 176 is provided with a groove 177 adapted to receive the formed end of the stay section and hold it steadily during the operation of coiling the same around the selvage wire. The seating plate 175 is provided with a lug 178 which is adapted to seat the formed end D in its place on the twisting plate 174. By means to be described, it will be shown that the twister plate is adapted to be revolved, while the seating plate is not, and when the two plates are brought with their matching faces adjacent or against the stay section. the lug 178 on plate 175 will hold the formed end D of the stay section in front of the acting faces of the driving lug 176 and seat the end I) of the stay section against the plate 17%l in the path of the groove 177 of the lug 176, so that as the plate 174. is revolved, the end D of the stay section will be seated in the said groove or engaged thereby and be carried forward by the lug and around the selvage wire A, after which resisting pressure of the wire holds it firmly in the groove 177.
The stationary position of the plates 174- and 175 is such that only a slight movement is needed to cause the groove 177 in the lug 176 to engage the end of the stay section. To prevent the driving lug 176 from interfering with the body of the stay section C during the revolution of the twisting plate, there is provided a seat, tapered or beveled face 17 9 on the plate 174, as shown in Figs. 22 and 24, against which the formed end of the stay section C is forced by the lug 17 8, the groove 177 in the lug 176 corresponding also to the angle of the bevel face 179 and conforms to the pitch at the end of the stay sections which are wound around the strand wires. The lugs 176 and 178 have inclined portions 180 and 181, so that the combined action causes them to separate suflicieutly at the point where the driving lug 176 passes the body of the stay section, which is held back against the opposite plate by the angle in which it is carried in the groove in the lug 176.
The knotter plates 172 and 173 operate in conjunction with each other in a manner similar to the twisting and seating plates 171- and 175. As previously referred to, Figs. 25, 26 and 27 represent a pair of these knotter plates for the intermediate wires and show them in various stages of operation, the resulting knot and coil of the coinciding stay sections requiring a proper relation of the same to each other and the knotter plates when the former are deposited on the strand wires. In the drawings, the plates are separated to afford a better view of the various steps in the process of forming the knot and coiling the stay sections by the knotter plates. Each of the knotter plates are provided with means for seating an adjacent stay section in its opposite plate and each pair of knotter plates are identical in so far as the
