SPECIFICATION vforming part of Letters Patent No. 617,253, dated January 3, 1899.
Application tiled March 4, 1898. Serial No. 672,577. (No model.) I
,To @ZZ 'wl/,om t may concern:
Beit known that we, FRANK B. MANVILLE and CHARLES SNVEEKS, citizens of the United ject is to produce a machine which will automatically sever wire into lengths, then bend one end of each length to form a loop, then twist the lapping portions to leave an eye, and finally deposit the finished ties in a receptacle, means being also provided for giving a signal when a predetermined number of ties have been so deposited, and provisions being also made for adjusting the feed ofthe wire to produce ties of the desired length.
Further objects of our invention are to produce a machine of this type which is simple in construction, in View of the several manipulations andtransfers of the lengths of wire, and which machine is capable of producing the finished ties at a high rate of speed.
To these ends our invention consists in the construction and combination of parts, substantially as hereinafter described and claimed.
In the accompanying drawings, Figure 1 represents a plan view of a machine embodying our invention. Fig. 2 represents a side elevation of the same and showing also a wire- Fig. 3 represents an elevation from the side opposite that shown in Fig. 2. Fig. 4 represents a detail elevation of the means for adjusting the length of reciprocations of the rack-bar. Fig. 5 represents an edge view of the parts shown. in Fig. 4. Fig. (5 represents an enlarged detail section of the feeding-disks and their bearings, said 'ligure being drawn on the line 6 (5 of Fig. 7 and looking in the direction of the arrow crossing said line. Fig. 7 represents a section on line 7 7 of Fig. G and looking in the direction of the arrow crossing said line. Fig. S represents a detail elevation of the friction strap or yoke for preventing backward rotation of the feedin g-disks and for holding the disks together to cause them to bite upon the wire. Fig. 9 represents a detail plan of the cutting-off mechanism. Fig. 10 represents a section on the line 10 10 of Fig. 9, looking in the direction of the arrow crossing said line. Fig. 1l 55 represents an enlarged detail plan view of the twisting mechanism. Fig. 12 repesents a side elevation and part section of the same. Fig. 13 represents a detail elevation of a portion of the twister-shaft and the sliding sleeve 6o thereon as viewed from the side opposite that indicated in Fig. 12. Fig. 14 represents a section on line 14 14 of Fig. 11, looking in the direction of the arrow crossing said line. Figs. l5, 1G, and 17 are detail elevations of the op- 65 erating end of the twisting-shaft and showing the bender in different positions. Fig. 18 represents a section on line 1S 18 of Fig. 15. Fig. 19 represents a detail elevation of the mechanism for operating the carrier or 7o reel. Fig. 2O represents a view from the right of Fig. 19. Fig. 2l represents a plan view of the parts shown in Figs. 19 and 20. Fig. 22 represents an enlarged detail elevation of the end of one of the arms of the rotary carrier 7 5 or reel. Fig. 23 represents a view from the right of Fig. 22. Fig. 24 represents a detail elevation of the temporary holder for the lengths of wire after they are severed. Fig. 25 represents a section on line 25 25 of Fig. 8o 24, lookin g in the direction of the arrow crossing said line. Fig. 26 is a view similar to Fig. 24, enlarged therefrom and showing the parts in a different position. Fig. 27 represents an enlarged detail elevation of the rotary carrier or reel and the holder from which the carrier takes the lengths. Fig. 2S is a view similar to Fig. 27, but reduced therefrom and showing more of the adjacent features of construction. Fig. 29 represents an elevation 9o from the right of Fig. 28, parts being in section on the line 29 29 of Fig. 28. Figs. 30 and 31 represent enlarged detail views, partly in section, of the means for signaling the finishing of a particular number of the baleties, the bearing for the worm-shaft being omitted from Fig. 30.
Similar reference characters indicate the same parts throughout the several views.
The bed-plate of the machine is indicated roo at l, supported by legs 2 and having suitable bearings for the main shaft 3 and counter'- shaft a, the former having a pulley 5 for a driving-belt (not shown) and the latter having the cams, hereinafter described, secured thereto. Atone end of the shaft 4 is a gear S,- meshing with and driven by a pinion 9 on the main shaft. fit the other end of the counter-shaft or cam-shaft @t is a gear 11, (see Figs. l, 3,1-, and 5,) which meshes with a gear 12 on a short shaft 13, mounted in a bracket 15, (see Fig. 5,) that is suitably secured to the frame of the machine. Both of the shafts 3 and et also have their bearings in this bracket 15 and also in another bracket 1G, (see Figs. l and 2,) secured to the frame or bed of the machine, at the front side thereof, as viewed in Fig. 2.
Secured to the end of the shaft 13 and adjacent to the gear 12 is a disk 17, having a dovetail groove 1Q formed diametrically across its face, in which groove a block 2O (see dotted lines in Fig. a) is fitted and adapted to be moved radially by means of a threaded rod 21, which passes through a similarlythreaded hole in said block in a well-known manner. Near the outer end of the rod 2l are fixed collars 22, between which is a block 23, secured in the groove 19. The end of the rod has a squared socket, whereby a wrench or key is employed to rotate the rod and adjust the block 20 toward and from the center of the disk 17. The said block 2O carries a wrist-pin 2i, which enters a slot 2G in a lever 27, the latter being pivoted to the frame, as at 2S. As will now be understood, the throw or extent of movement of the lever 27 may be adjusted by means of the threaded rod 21, and since this lever operates the feed, as presently described, the adjustment of the block 2O and its wrist-pin 2st by means of said rod 21 effects the desired adjustment of the feed of the wire.
The feed-disks 30, between the grooved peripheries of which the wire is gripped and by the rotation of which the wire is drawn from a suitable coil or other source of supply, (not shown,) are represented in Figs. 1, 2, and 3, and their operatingmechanism is shown more in detail in Figs. G, 7, and 8. A standard 3l, rising from the bed-plate l and forming part of the frame of the machine, is provided with two offsets 32, (see Figs. 3 and 6,) which are provided with dovetail grooves in line with each other to form ways for a slide 33, the upper and lower edges of which are toothed to form a rack. rl'his slide-rack is connected with the upper end of the lever 27 by a pitman or connecting-rod 34, whereby movements of said lever reciprocate the sliderack to a greater or less extent, according to the adjustment of the wrist-pin above described.
ln the standard 3l are bearings for the sleeves or tubular shafts 35, one end of each of said shafts having secured thereto or integral therewith a pinion 36, which meshes ariete with one of the compound pinions `17, presently described, and the other end having a ratchet-toothed disk 37. (See Figs. G and 7.) Each sleeve or shaft receives or forms a bearing for a shaft 3S, on the outer end oi which is mounted one of the feeddisks 30, having a pawl 39 in engagement with the ratchet 37. The hubs of the feed-disks are somewhat extended to form bearing-surfaces 40 for friction-pads 41, of any suitable material, said pads being held in position by a yoke or strap l2, (see Fig. 8,) the upper ends of which are threaded and passed through a cap 43 and are provided with nuts il, by means of which the two friction-pads maybe adjusted to bear with more or less pressure on the surfaces 40.
As shown in Fig. 0, one side of the stand ard 31 is provided with threaded sockets l5. These are to receive studs 4G, (see Fig. 3,) on which are freely mounted compound pinions 4,7, the larger of which mesh with the pinions 3G and the smaller of which mesh with the two racks formed on the reciprocating slide It will new be understood that the reciprocations of the slide-rack canse the ratchets 37 to have a reciprocating rotary motion through the medium of the tubular shafts 35 and the pinions 3G and idlerpinions i7, and that when this motion is in one direction the disks will be caused to rotate in the direction of the arrows thereon in Figs. 3 and 7, owing to the enga-gement of the pawls with the ratchets, and that on the return movement of the reciprocating parts the ratchets move freely under the pawls, while the disks are prevented from retrograding by the friction-pad mechanism above described. rlhe diameters of the feed-disks are such and the compound pinions `17 are so proportioned for multiplying speed that with a somewhat limited throw of the lever 27 we are enabled to obtain a wire-feed of any desired length, according to the dimensions and the throw adjustment of the lever.
The wire is passed directly between the feed-*disks and is preferably drawn through a wire-straightening mechanism, (indicated at 48 in Fig. 2 in a conventional manner.) This mechanism maybe of any preferred form, and we do not illustrate itin detail, it being suliicient for the purposes of this specification to state that it is mounted on a standard 50 and is of a type that is rotated about the wire as it is drawn along' by means of a power-driven belt 49.
A fixed guide 51 (see Figs. 2, 9, and lO) is provided with a tapered end to enter the space between the feed-disks at the discharge side ot' their contacting points and has its internal longitudinal bore or passage of a size to receive the wire as it leaves the feed-disks. This guide is secured in an ear 52, projecting from a plate 53, by means of a set-screw 54:,
and said plate is adj ustably secured on a portion of the standard 31 by means of a screw IOO IIO
` ceivers.
cir/,25s a passing through a slot 5G in said plate. The rear end of the guide is preferably somewhat rounded, and with this a cutter 57 cooperates to sever the wire after each feed movement has ceased. The cutter is adjustably secured to a slide 58 by means of a screw 59 passing through a slot GO in the cutter shank, and said slide is fitted to a groove or way formed in the plate 53 at a right angle to the guide 5l. A spring 6i is confined between a portion of the plate 58 and an angular offset 62 of the slide 58 and tends to hold the slide and cutter in inoperative positions and to return them after the wire has been severed, aswill now be described.
A lug or shoulder G8, rising from the cutter-slide, is operated against by one end of a lever 64, (see Fig. 1,) which passes through an opening 65 in the standard 31 (see Fig. 6) and is fulcrumed in said opening by a pin, as indicated by the dotted circle GG in Fig. l. The other end of the lever 64 carries a pin or roll 67, which is operated against by a cam G8 on the end of a drum 69, mounted on shaft 4. This cam operates quickly and at a time after the feed or advance of the wire has ceased.
Referring to Fig. 3, it will be seen that at some distance from the main frame of the machine is a leg or standard 70. rlhis, in connection with parts of the main frame, supports the parts which temporarily hold the severed blanks or lengths of wire and also carries the outer bearing for the shaft of the rotary carrier or transferrer, hereinafter described.
The upper end of the standard .70 is connected with a standard 7l, rising from the bed-plate l, by means of a rod 72, which supports the temporary receiver or table for the blanks. Ne have illustrated but one standard but it is to be understood that more may be employed and that the receiver or table may be of any length to accommodate the greatest length of blanks desired. As shown in the drawings, the receiver is in two sections to permit the ends of one set of arms of the tran ferrer to pass between the sections, the other set of arms being beyond the end of the receiver, (see Fig. 8;) but when more sets of transferrer-arms are employed there will be added standards 7 O and sections of re- The two sections of receivers illustrated are supported from the rod 72 by means of hangers 78, (see Figs. l, 2, and 8,) and each section consists of a base portion or table 74:, to which is hinged, by means of suitable ears, a cover 75, having a groove 7G in its lower face, (see Figs. 24, 25, 26, and 27,) the two sections of covers being connected bya bridge or strip 77, as shown in Figs. l, 2, and 3.
The groove 7 G is in line with the exit end of the orifice for the wire in the guide 5l and receives the wire before it is severed by the cutter and holds it while being cut off. ln order to release the blank from the groove, so that it may be taken by the vlingers at the ends of the arms of the transferrcr, (not yet described,) it is necessary to raise the cover on its hinges. In Figs. 24E to 27 we illustrate a single arm 7 8, extending back of the hinged edge of the cover; but it is to be understood that in practice there may be a number of such arms 78, each having means to depress it to raise the front edge of the cover, as shown in Figs. 26 and 27.
rlhe arm 78 is depressed at the proper time by means of an elbow-lever 79, pivoted at 8O to one of the hangers 78 and having its longer or horizontal arm extending over the arm 78. The upper arm of the elbow-lever is connected by a link 8l with another elbow-lever 82, pivoted at 83 to another hanger 7 9. The lever 82 is connected by a link 84 with an arm 85 of a roclcshaft 8G, (see Figs. 24 and 26 in connection with Figs. 1, 2, and 3,) mounted in a bearing at the upper end of a standard 87, rising from the bed-plate of the machine. Another arm 88 of the rock-shaft is provided with a pin 89 and has attached to it one end of a spring 90, the other end of the spring being connected at 91 to the bed-plate of the machine. (See Figs. 24: and 26 in connection with Fig. 3.) The parts are normally held in the positions shown in Figs. 3, 24, and 25 by the tension of spring 90, thus permitting the cover to remain closed. To raise the arm 88 and through the connections described cause the elbow-lever 79 to depress the arm 78 and raise the cover, we provide ayielding finger 92, pivoted to the slide at 93. (See Fig. 8.) rlhe finger carries a pin 9i on one side, and back of the linger a pin 95 projects from the slide and acts as a backstop to prevent the finger from moving in that direction. A spring 9G connects the pins 9i and 95 and serves to normally hold the finger against the back-stop. During the backward movem ent of the slide-rack 38 the spring 96 yields and permits the pivoted finger 92 to pass under the arm 88 without disturbing the latter; but on the forward movement of the slide-rack the finger is held upright by the back-stop 95, and consequently the upper end of the finger slides along the under side of the arm 88 and lifts it, and thus through the connections described raises the cover 75. The cover 75 is held in raised position all the time the finger 92 is passing along the straight under side of the arm 88 toward the end of the latter, thus giving the transferrer-arm 123, which is hereinafter described, time to carry a wire blank out from under the cover '7 5.
It is to be borne in mind that the forward movement of the slide-rack just described does not feed the wire, said feed taking place only when the rack is moving to the left from the position shown in Fig. 3. Therefore the cover 75 is lifted to release the wire after the feed has ceased and after the requisite length has been cut olf and just before the next feed movement of the disks.
As hereinbefore stated, there are two or morev sets of arms in the mechanism. for tak- IOO IOS
ing the blanksl from the iemporz'iry receiver just described. 1n the drawings there are tivo of such sets illustrated, the ends of the arms of one set passing betiveen the adjacent ends of tivo sections of the receiver. During each feed of the Wire these arms are stationary and the ivire is fed through openings in the ends of the arms which are at that time in alinement with the guide 51 and with the groove of the temporary receiver. Ve will now describe the construction and operation ci' this mechanism which takes the blanks from said receiver and transfers them first to the twisting mechanism and then to the final receiver.
1n connection With Figs. 1, 2, and 3 reference is to be had to Figs. 10, 20, 21, 22, 23, and 27. The shaft 07 of the rotary transferrer is mounted in suitable bearings 0S and 00, supported, respectively, by the standards 70 and 71, and said bearings are vertically adjustable in order to insure that the openings in the ends of the arms may be brought into exact alinement with the groove 7 0 of the temporary receiver. The means by Which this adjustment may be effected are illustrated in Fig. 10, in which the bearing-sleeve 09 is shown as provided with t\vo sockets to re ceive the ends of screws 101, tapped through suitable openings in portions of the standard 71 and provided with set-nuts 102. The inner end of the shaft 07 extends through the bearing-sleeve .10 and has secured thereto a disk 103, provided with four equidistant notches 101, each of which has a radial side and a tangential side, (see Fig. 20 in connec tion With Fig. 19,) and secured adjacent to or forming a part of the disk 103 is a collar or ila-nge 105, Which also has fonr equidistant notches, as at 100, these latter, however, hav ing sides Which are substantiallyparallel, but tlaringsomewhatat their months, as indicated by dotted lines in Fig. 20. A bolt 107 is adapted to enter any one of the notches 106 to hold and lock the iiange 105, disk 103, and the shaft 97 and its arms in proper position for the alinement of the openings in the ends of said arms above mentioned and to be presently described in detail. This bolt 107 is mounted to slide in a horizontal groove or Way formed in a block 10S, that is fixed to a portion of the frame of the machine, and the said boltis normally held in one of the notches 100 by a spring 100, coiled abont a pin 110 in the side of the block and having one end secured, as at 111, and the other end pressing against the outer side of a pin 112, projecting from the side of' the bolt.
Loosely pivoted on the end of the shaft 07 is a lever 113, having one end formed as a cam-surface 11i, which is adapted to engage the inner side of the pin 112 of bolt 107 and force the bolt out of the notch in the flange against the action of spring 100, and thus release the transferrer. The other end of the lever 113 is provided With a pawl 115, which is kept in engagement with the periphery of the disk 103 by a suitable spring. (Not shown.) XVhen the lever 113 is moved onefourth of a rotation to the right from the position shown in Fig. 20, the pawl 115 enters the notch 101A at the right just as the cam 111 engages the pin 112 of the bolt and causes the release of the transferrer, so that on the return movement of the lever to the position shown in Fig. 20 the disk 103 and the entire transferrer is given a one-fourth revolution. These oscillating movements of the lever are imparted by means of a lever 110, pivoted at 117 (see Figs. 2 and 3) to a bracket on the under side of the bedplate and having at one end a roll 11S, riding on a cam 110, carried by shaft t. A spring, as at 120, keeps the roll in engagement With said cam, and the other end of the lever 11G is connected with the lever 113 by a link 121, adjustably ,jointed, as at 122, in order to secure exactness in the throiv of the lever 113.
The means for intermittently rotating the transferrer having thus been explained, ive will noiv describe the construction of thc details thereof, referring particillarly to Figs. 21, 22, 23, 27, 2S, and 20 in connection with Figs. 1, 2, and 3.
The shaft 07 is provided with a plurality of sets of arms, each set consisting of four arms 123 equidistant from each other. As the sets of arms are duplicates of each other, description of one set and of the means for retaining the blanks in their openings and for discharging them therefrom will be sullicient for all. In the end of cach arm 123 is an open slot or recess 124, which is normally closed by a latch or hook 125, formed on the outer end of a lever 120, pivoted to the arm at 127 and having a pin 128 projecting from its other end. A spring is coiled about the pivot-pin and has one end connected to the pin 128 and the other end connected to a stud 130, projecting from the arm 123. The spring has a tendency to hold the lever in engagement with the stnd130, with the hook overlapping the recess 12a, so as to form a substantially circular opening for the Wire. On the side of each arm opposite that to which the lever is pivoted is a stud 131, having a recess corresponding with the recess 121 and provided with a conical entrance-mouth (see dotted lines in Fig. to guide the end of the Wire as it approaches the arm As each arm reaches its lowermost position the hook is opened to permit the wire to be dropped out by means of a stop or lug 132, (see Figs. 2S and 20,) carried by an arm 133, adjustably supported in a slideway formed in a bracket 131x, carried by a suitable part IOO IIO
of the frame. This lug 132 is arranged in the path of movement of the end of the lever 120, so that when said lever 120 contacts with the lug 132 it will first cause the hook to open the recess in the arm 123 to release the Wire or baletie, and then pass by the lug, so that the spring 129 Will cause the hook to close the recess again.
.Before the operation of releasing the tie, as just described, takes place the wire blank has had one end doubled and twisted while held by the arms 123 in a stationary position half-way between the posit-ions of receiving and discharging, and We will non7 describe4 the mechanism for performing this operation. Referring to Figs. 1, 2, and 11 to 18, inclusive, the shaft of the twister is indicated at 135, mounted in a bearing formed in a block 136 on the bed-plate 1, the cap-piece of the bearing being indicated at 137. The rearend of said shaft is provided with a pinion 138, which meshes with and is driven by a gear 139 on a short shaft which is mounted in a bearing in a block 140 and hasasmaller gear or pinion 141 at its other end. The pinion 141 meshes with and is driven by a rack 142, fitted to slide in a suitable guide or Way (not shown) in the side face of the block 140 and having a stud provided with a roll 143, which enters a cam-groove 144 in the drum or cylinder 69 on shaft 4. Each rotation of the shaft 4 and its cam-cylinder imparts to the slide-rack a complete forward-andback movement, and this through the multiplyinggearing 138, 139, and 146, above described, rotates the shaft 135 several times in one direction (about three as now geared) and then returns the shaft. The cam-groove 144, however, is formed so as to permit a dwell in the movements of the shaft at the end of each series of rotations in one direction, for a purpose presently explained. The other end of the shaft 135 is divided so as to form a recess 145 to receive one end of the Wire blank cc as it is passed thereto by the arms of the transferrer at the end of the first quarter-revolution of said transferrer. The ends of the two arms 146 each side of the recess 145 are provided with openings in line with each other to receive a pin 147, the inner end of which is beveled, as at 148 in Fig. 18, to prevent the end of said pin from catching on the wire when the pin is moved inward, and the outer end of said pin 147 is connected to a lever 149, pivoted to an ear 150 on the outer side of one of the arms 146. The lever 149 is provided with a pin 151, on Which a spring 152 bears to hold the lever normally in the position shown by full lines in Fig. 11, with the pin 147 withdrawn from across the recess 145.
TWO lugs 153 depend from the lower edges of the arms 146 and support a pin 154, which in turn supports and guides the bending-iinger 155. This bending-finger is of peculiar construction, its outer portion or tip 156 eX- tending upward in an inclined direction and then curving forward and downward and having a groove 157 `formed in its upper edge, which groove continues over and under the end, as clearly shown by the full lines in Fig. 11 and by dotted lines in Figs. 15, 16, and 17. The intermediate portion of the bending-finger is provided with a slot 158, `that is curved in a direction substantially the .reverse of the curvature of the tip 156, and this slot receives and serves to guide the finger on the pin 154, so that when a wire has been lowered by the transferrer to the position indicated by full lines in Fig. 12 and the 1ever 149 has been operated by the means presently described to move the pin 147 across the recess 145 and the finger 155 is then advanced by the means presently described the tip of the finger bends the Wire up and over the pin 147 until the short endlies close to the portion of the Wire that is still lying in the arms of the transferrer. (See Figs. 12, 15, and 16.) To effect these movements of the lever 149 and finger 155, We employ a sleeve 159, movable on the shaft 135 and provided With an annular groove 160, which receives the arms of a yoke 161, attached to a slide-bar 162. This slide-bar is itted to a groove in the base of the block 136 and has its rear end provided With a roll 163, Which enters a cam-groove 164, (see dotted lines in Fig. 1,) formed in one side of a disk 165, carried by shaft 4. The time of operation of this cam-groove is such as to advance the sleeve 159 while the shaft 135 is stationary, as heretofore described.
The sleeve 159 is provided with a projecting Wedge or incline 166 in line with the end of the lever 149 (see 'Figs 11, 13, and 14) and with tWo ears 167, (see Figs. 12, 13, and 14,) Which are provided With short slots 168. The inner end of the finger is fitted between the ears 167 and carries a pin 169, Which rides in said slots. By this construction when the sleeve 159 begins its advance movement the incline 166 first rides under the end of lever 149 and moves the latter and the pin 147 from the position shown in full lines in Fig. 11 to the position shown by dotted lines in said figure, and then the inner ends of the slots 168 come in contact with the pin 169 of the finger 155 and advance the latter from the position shown by full lines in Fig. 12 to the position shown by dotted lines in said figure and bending the Wire over the pin 147.
Referring now to Figs. 1 and 2, it will be seen that the side of the block 108 is formed as a -fixed jaw 170, with which a movablejaw 171 coperates, the -latter being carried by a lever 172, pivoted to the bed-plate 1 at 173 and having its other end provided With aroll 174, which is acted upon by a cam 175 on the side of the disk 165, a spring 176 being employed to keep the roll in engagement With the said cam. The timing of the operation of this cam 175 is such as to cause the jaw 171 to move toward the jaw 170 and grip the doubled Wire at about the point indicated at y in Fig. 16 just after the finger 155 has ceased to operate. Immediately after this gripping action takes place the straight por tion of the cam-groove 144 has left the roll 143 and the inclined portion of said groove acts on the roll to move the rack 142 and, through the gearing before described, the
IOO
IOS
shaft 135 is rotated and the wire is twisted, as indicated in Fig. 17, leaving a loop or eye at the end of the finished tie.
In order to hold the shaft 135 in exact position, with the recess in a vertical plane to permit the wire to be carried into said recess by the transferrer and to permit the iinished tie to be carried down and out of said recess by the transferrer at its next quarterrevolution, we affix to the shaft a colla-r 177, having a fiat side 178. A plate (see Figs. 1 and 2) is secured at 011e end on the cap-piece 137 and has a slot to receive a guidepin 180, rising from said cap-piece. The free end of the plate 170 is formed as a block 181, overhanging the end of the cap-piece and resting on the collar 177. A flat spring 182 is secured at one end 183 and bears at its other end on the plate 170. The collar 177 is so secured to the shaft 135 that when its flat side 178 is under the block 181 and the shaft 135 is not being positively rotated in either direction the recess 115 is securely held in the plane described. After the rotation of the twister-shaft in one direction to complete the eye of the tie it dwells or remains non-rotary while the eye-forming pin 117 and the bending-finger are withdrawn and immediately thereafter the transferrer-arms begin to rotate another quarter-revolution to bring another blank to the bending and twisting mechanism, while the rack 142 moves in the return direction to reverse the shaft 135 to prepare it for receiving the next blank. At the end of this return movement of the rack its roll 113 is in the other straight portion of the cam-groove 111 and the shaft 135 is held in proper position by the block 181 bearing on the fiat side of the collar 177.
r1`he collar 177 is flattened for only a portion of its length, as shown in Fig. 12. lVhen the block 181 rests upon the flat side 178, it acts as a hook or stop to prevent forward motion of the shaft 135 while the sleeve 150 is being' moved forward to double the wire by means of the pin 1417 and the linger 155. As the twister-shaft 135 makes its first revolution the block 181 rides onto the untlattened portion, the shaft having su fiicient longitudinal play to permit this, and the twisting of the wire loop draws the shaft 135, and hence the collar 177, forward, so that by the end of one revolution and until the shaft is returned to its iirst position after a bale-tie is finished the block 181 rides upon the full round part of the collar 177 and allows free end movement of the shaft 135 as the twisting of the loop progresses. The forward movement of the shaft is limited by a yoke-piece 138', (see Figs. 1 and 2,) adjustably secured to the rear end of the cap 137 by the screw 183, passing through a slot 138 in said yokepieee, the said yoke-piece straddling the shaft and serving as a stop against which the pinion 188, secured to the shaft, may abut. This contact of the pinion with the stop or yokepieee occurs just before the shaft 135 has iinished its revolution, thus enabling a tight twist to be given.
The finished tie is held in the openings or recesses of the arms 123 by the hooks 125 until the ends oi' the levers 120 contact with the stops er lugs 132, (see Fig. 28,) it being understood that there is one of said stops or lugs for each set of arms 123. This contact opens the hooks or latches which hold the finished tie and permits the latter to drop into a final receiver or rack composed of arms 1.8i-, which are suitably connected with portions of the frame or standards.
The means for audibly indicating when a predetermined number of finished ties have been deposited in the rack are as follows: A star-wheel 185 (see Figs. 28, 20, 30, and 31) is carried by a shaft 180, mounted in a bearing 187, supported by or formed in one of the standards-in this instance standard 70. Each of the arms 23 of the adjacent set provided with a projecting lug or pin 188, which is adapted to engage one of the teeth of the star-wheel and partially rotate it as each arm 123 passes said star-wheel. rlhe other end of the shaft 186 carries a worm 180, meshing with a worm-wheel 100, mounted to rotate on a stud 101, which is attached to and supported by a suitable arm or bracket oi' the standard 70, said arm being indicated in section in Fig. 30 at 102. The stud 101 carries a fixed disk 103, from which a piu 101 projects, and mounted on the stud is a sleeve 105, a bell 100 being mounted on the outer end of the stud. Projecting from the sleeve is an arm 107, having a pin 10sy and a spring 100 is coiled about the sleeve and has its ends bearing against the pins 10-t and 108, with a tendency to keep the sleeve 105 and arm 107 in the position shown in Fig. 31. Another arm 200 projects from the sleeve and supports the spring-shank 201 of a bell-ham mer 202. Pivoted to the disk 103 at 203 is a lever 204, having its longer end 205 provided with a tip or toe 200, adapted to bear on the lower side of the arm 200, and the other end 207 adapted to abut against the other side of the sleeve to limit the outward movement of the longer end 205 of the lever, it being understood that the tendency of spring 100 to hold the parts in the position shown in Fig. 3 causes the arm 200 to press the toe 200 of the lever outward.
Projecting from the side of the worm-wheel 190 are pins 208, there being live of such pins iu the form of construction shown in Fig. 31, which pins successively operate to cause the hammer to strike the bell in the manner presently described.
The operation of this portion of the meeh anism is as follows: Each quarter-revolution of the transferrer discharges a. finished tic and also partially rotates the star-wheel 185. This causes a slight rot-ation of the wormwheel, and one of the pins 208 moves a short distance along the cani-shaped outer surface of the longer arm 205 of the lever, and the IOO successive operations ol' the star-wheel finally advance said pin along the lever and gradually carry the arm 200 upward and move the sleeve 105 against the tension of spring 100. When the pin 20S that has been so operatin g alon the vlever reaches the shoulder 209 thereof, the lever is released, since the edge of the lever, from the shoulder 200 to the tip 200, is concentric with the center of the pivot 203 of said lever. The lever being thus released, the sleeve 195 and the arm i207 are thrown suddenly back by the spring 100 to the position shown in Fig. 3l, and this sudden movement throws the striker 202 against the bell, the position of which is indicated by the dotted circle in Fig. 31.
rlhe operations of the different parts of the machine having been mentioned in connection with the detailed description of the mechanisms, the operation of the machine as a whole, if not already apparent, will be made clear by the following general description: The wire from which the ties are made is drawn from a coil or other source of supply (not shown) through the straightener 4S, if it is found necessary to so treat the wire, and it then passes to the disks B0, which have an intermittent rotation in the direction of the arrows in Fig. 2, the extent of this feeding movement being adjusted according to the length desired for the completed ties. The wire is pushed by the disks through the guide 51 and through the passage-way in the temporary holder or receiver 71- 7 and through the openings in the arms 123 of the rotary transferrer. Then the proper length has been so fed, the disks cease to rotate and the cutter 57 severs the wire at the rear end of the guide. rl`hen the temporary holder opens and the shaft 07 of the transferrer makes one-fourth of a rotation and brings other arms 123 into position to `receive a severed blank and the first one is moved to carry the just-severed end into the recess 145 of the twister-shaft 135. The pin 147 is next moved across the recess 145, and the bending- Iingerl carries the short end of the wire around the pin 1.45, after which the jaw 171 clamps the doubled portions of the wire and the shaft 135 rotates to twist the doubled portions of wire between the pin 147 and the holding-jaws. rlhe looped and twisted end ofthe wire is then released both by the holding-jaws and by the pin 147, and the shaft 97 of the transferrer makes another one-fourth of a rotation, so that the arms thereof bring the second blank to the twister and carry the completed tie down to be discharged into rack 181 for holding a number of the completed ties. Each intermittent movement of the transferrer partially operates the gearing, which iin ally causes the hammer 202 to strike the bell 190 and indicate that the predetermined number of ties have been deposited in the rack.
