MACHINE FOR SETTING- EYELE'I'S AND THE LIKE.
Application filed April 7, 1919. Serial No. 288,076..
To ZZ 'whom t may concertar.'
Be it known that Bonnin' SMITH, late of Stoughton, in the county of Norfolk and State of Massachusetts, deceased, invented certain improvements in Machines for tietting Eyelets and the'like, of which the .following description, in connection with .the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to fastener-inserting` machines such as those used for inserting and clenching eyelets, lacing-hooks and gromets, and an important object, generally stated, is to provide an improved machine pf general utility capable of operating satisfactorily on certain special kinds of work that require different treatment .from that required by the morecominon kinds of work.
The setting of eyelets and grornets in articles such as canvas cartridge-belts for eX- ample, involves difficulties that are not encountered with the more common kinds of work such as shoe uppers and corsets. The canvas of which cartridge-belts, machinegun-belts, haversacks, and other articles used for military purposes, is relatively thick and tightly woven. When setting fasteners in articlesmade of woven material it is not feasible to cut or punch out portions of the fabric to form the holes in which the fasteners are to be set, for the reason that such cutting or punching would sever the woven strands and the fabric would thereafter pull away from the fasteners and thus lose the reinforcing effect of the latter.
For this reason it is customary to form thek hole in the fabric by spreading the int-erwoven strands sufficiently to form the holes for the fasteners. It has been found, however, that the sharply pointed punches used for this purpose become so tightly embraced bv any relatively heavy and tigl'itly woven fabric that the latter becomes distorted in consequence of accidental edgewise displaceyment and skewed by twistingof the punch incidentally to feeding the work. In order, therefore, to avoid these objectionable results the present invention provides iniproved mechanism which, in the illustrated embodiment, comprises a swivel punch, that is to say, a punch that is free to turn relatively toits carrier, the freedom of the punch'soto turnenabling the punch to reinain in fixed relation to the work in the event that the latter should be twisted relatively to the punchcarrier or in the event that'the punch-carrier should execute angular motion relatively to the work while feed-V ing it. i lt may also be desirable and advantageous in some cases to render the clenching tool capableof'turning about its axis relatively to its carrier, and when, asin the illustrated machine, the clenching elementA and the punch areintegral parts of the same tool they would both be capable Vof turning as specified. The invention therefore comprises the feature of a clenching tool constructedland arranged to turn about .its axis relatively to its carrier while the machine is in condition for use. d Y.
Another object Aof the invention is to adapt, for special work of the kind hereinbefore mentioned,- machines of otherwisewell-known construction designed for operating upony Cartridgebelts, for example, may. require two, three,
the more common kinds of work.`
the latter that, when-f it is attempted to setthe fasteners at a relatively great distance from an edge of the work, the latter interferes with the i'aceway and with the fasteners therein. This not only displaces the work from the desired position but thel work ob-` structs the flow'of fasteners in the raceway.
ln order to avoid such interference the invention provides means arranged to deflect upwardly that marginal portion of the work that would normally touch the raceway, and to support such portion above the raceway. rllheraceway is thus enabled to be reciprocated horizontally asusual without agitating the work and without subjecting the of the work.
fasteners therein to interference on the part ln consequence of this feature of the invention there is a tendency on the part of the work to deviate from a straight path of feeding motion, and accordingly another object is to provide means to counteract this tendency. ln this connection a feature of the invention consists in a worleguide arranged to control the edge ofthe work opposite to the one that is deflected as aforesaid.
@ther features of the invention are hereinafter described and claimed, and are illustra'ted by the drawings. For convenience in illustrating the invention, but without imposing any undue limitation thereon, the various features are illustrated as being' embodied in a fastener-inserting machine of the same general type as that shown and described in United -States Letters Patent No.
1,205,277, granted November 2]., 1916, upon anapplication of WV alter Shaw. Excepting as hereinafter specified it is to be understood that the machine shown and described herein is similar to that shown and described in the aforesaid patent.

Fig. 3 reperesents a sectional view in the vertical plane indicated by line 3-3 of Fig. 2, with the addition of the fastener-setting members and the work punch;
Fig. 4 represents a sectional view similar to 3 showing the parts in another position wherein a fastener carried by the lower setting member is about'to be inserted in the work;
Fig. 5 represents a sectional view in a vertical plane showing the setting members completing the settinv operation; and AFig. 6 represents a perspective view of a fragment of the work-supporting' table including two separable plates arranged to co-operate with the punch. K,
The upper setting` nie'rnber of the fastener-inserting mechanism is indicated at 10, and the lowersetting member is indicated vat l2. The punch for forming a hole in the work to receive a fastener is indicated at i4 and, in the present instance,'is an integral part of the setting' member l0. This construction is commonly termed a combined punch and set. The punch 14E, in the present instance, is pointed so as to form the hole by spreading the stock instead of ratones center the fastener' relatively to the setting members.
The lower` setting member is aiiiXed to a plunger i8 and the latter is arranged to slide up and down in guides one of which is indicated at 2G in Fig. i.- A cam roll 22 carried by the plungerl co-acts with a cam 2i to movie the plunger up and down. rlChe cam is fixed to a driven shaft 26 and the latter is arranged to rotate in suitable bearings in the frame 28 of the machine.
The upper setting member is carried by a carrier 30 which, in the present instance, is a lever. A sleeve 32 is inserted in 'the carrier to hold the setting member, and is provided with external screw-threads 34 which engage internal screw-threads formed in the carrier. rlhe sleeve may, therefore, be adjusted up and down relativelyto the carrier by turning it. rllhe lower end of the sleeve is reduced in diameter and is provided with external screw-threads r36 to coact with a binding nut 38. The carrier is bored and tapped to receive a set screw 40, the latter being arranged to engage a smooth rportion of the sleeve to prevent the latter.
from turning while the nut 38 is being tightened. rlhe setting member l0' is formed to turn relatively to the sleeve 32, and its upper end is provided with a head 42 arranged to rest upon the upper end of the sleeve. A. screw plug del is screwed into the carrier above the setting member to bear against the upper surface of the head 4:2
so as to sustain the stress incidental toy clenching a fastener. ln practice the plug id will be adjusted to take up substantially all lost motion between the setting' member and the carrier without, however,bind ing the setting member so as to interfere with its freedom to turn relatively to the sleeve. The plug all. is provided with a bindnrt i6 by which it may be held in the desired position of adjustment.
The carrier 3() is arranged to rock upon a fulcrum member 418 the axis of which is substantially horir/iontal.l This fulcrum member en'. y one of which is indicated at 50, this construction being` shown in the aforesaid ,patent. The blocks 50 are mortised into a forked portion at the upper end of a post 52, the axis of which is substantially vertical. The post is arranged to turn about 4its airis in bearing 5iin the frame 28, and is provided with an arm 56 by which it may be oscillated to impart feeding motion to the carrier 30. The feeding motion is derived y.nds through two sliding blocks from a cani 58 carried by the shaft 26 and is transmitted by a cam-lever 60, rock shaft' $2, arm Gil. and links 66 and 68. The two links and a third link, indicated at 70, are connected by a common pivot member 72, and are adapted to be adjusted in such manner as to vary the ent-ent of motion transmitted to the arm 56.
The up-and-down motion oi the settingmember is derived from a cam il. and is tr nsmitted by a vertically movable plunger To to the rear end ofthe carrier 30. The upper end of the plunger is provided with horizontal parallel members 78, 'i' 8 that form a yoke, the ends of the members being connect-ed by rods 80. The connection between the yoke and the rear end of the carrier emn bodies a ball-and-socket construction. the ball member 82 being iixed to the carrier. and the socket members 8d being disposed between the ball and the membersV 'i8 respectively. The socket members are provided with rollers 86, and the latter are arranged to move in grooves 88 formed in the members T8, the grooves being curved to impart a. slight longitudinal movement to the carrier in consequence ot the feeding motion imparted to the carrier. rlfhe carrier thus caused to execute a compound motion1 the result of which is to move the sett-ing member 10 in a straight line.
The machine is provided with a stationary work supporting table 90 which, for the purpose of supporting` relatively long ar icles such as cartridge-belts, is preferably extend-- ed a considerable distance to the right and lef-tot' the setting members. 1n the vicinity olf the setting members the work table is eut away to receive a pair of cooperative pla-tes 92. 92. and is provided with undercut grooves to receive tongues 9d formed on opposite edges of the plates. rIhe plates are thus mortised into thetable and are capable of sliding; relatively to the table and relatively to each other in lines transverseto the lines of feeding movement of the work. The plates are normally drawn toward each other by a spring 9G, the ends of which are anchored respectively to pins 98 carried by the plates. These-` pins extend downwardly from the plates through slot-s 100 formed in the table. The abuttingedges of the plates are beveled as shown by Fig. 6 to facilitate the insertion olE the punch between them. The plates are adjusted initially by stop members 102 clamped to the under side ot the table 90 in position to engage the pins 08. rl`he stop members'are adjustable relatively to the table, and in practice they are set at positions that will cause the abuttingF edoes of the plates 92 to register with the point orn the punch A. .When the plunger .70 at the rear of the machine is moved upwardly by its cam the punch moves downward-ly through 'the work m, and, on coming in contact with the confronting beveled ed ,ses
of the plates 92 it forces the latter apart. rlhe work .fr as shown' comprises two layers and isintended to represent the thick and' tightly woven fabric of a cartridge-belt.l
rlhe punching motion occurs when the punch is displaced .laterally from the line ot the j setting member and a fastener to rpass therethrough.
Fasteners such as that indicated at a are supplied to the lower setting member by an inclined raceway 108. This raceway, like the corresponding raceway in the aforesaid.
patent, is reciproeated horizontally toward the front and rearA of the machine in timed relation to the movements of the lower settingmember such that the leading fastener in the raceway will occupy a `position in registration with the spindle 16 during the first stages ot upward movement of the plunger 18. The spindle 16 is thusy inserted through the'barrel of the leading fastener, and before the lower setting member has been raised far enough to engage the raceway the latter is retracted toward the rear et the machine and is maintained out of the path of the setting' member until the latter has subsequently descended far enough to clear it. rlhe raceway is then movedtoward the front to present the nent fastener in the path of the spindle. The lower end ot the raceway is provided with a yielding stop by which the lea-ding;- astener prevented rom escaping until it is withdrawn by the spindle as the raceway is retracted.
ln consequence of the inclination of the racewa-y and its close relation to the setting' members, the raceway necessarily intersects the path that would normally be traversed by the rear edge of the work. purposes the term work is meant to relier to the kind ot work in which the fasteners are set at a relatively great distance from the rear edge. In order, therefore7 to provide adequate support for the work without incurring interference between the table and the raceway, the rear edge of the table is cut away toorm a notch 112 (Fig. 2) in which the raceway moves incidentally to its reciprocating to the front andrear. This7 however, does not avoid interference between the work andthe racewa-y7 or the tas-` teners in the latter. ln order, therefore, to avoid suoli interference a guard 114: is ar- For present CIK ` n Lacoste ranged in position to hold the rear marginal portion of the work above and out of Contact with the fasteners. 1n the present instance this guard is aixed to the table and covers the notch 112. The guard is inclined substantially in accordance with 'the rinclination of the raceway, being higher at its rear edge than at its front edge. A presserfoot 115 is arranged to depress the work against the table between the guard 114 and the hole 106.
ln order to utilize the machine to insert two, tli-ree or four, as the case may be, fasteners the machine is provided with two stationary but adjustable worl guides 116 and 122. 1n the present instance these guides are c aniped to the work table, the guide 116 being provided with slots 120 for the reception of clamping screws 118, and the guide 122 being provided with slots 124i for the reception of clamping screws 1.26. @ne of these guides, preferably that at the rear of the table, is relatively near the line in which the fasteners are inserted. When a piece of work, for example, that indicated at m in Fig. 2, is placed upon the table with its rear edge abutting against the guide 122 the front marginal portion of the work may overlie the front guide, in which event the front guide is not effective to determine the line in which. the fasteners will be inserted. The work will progress from right to left and its rear marginal portion will pass over the guard 11swithout engaging the raceway or the fasteners therein. A slight manual effort is sufficient to l'eep the rear edge of the work against the guide 122, the work-engaging surface of which is parallel to the lines'of feeding movement of the punch. When, under the conditions last stated, the first series of fasteners has been inserted the work. may be returned to its original starting position for the purpose of inserting a. second row of fasteners in another line. For this purpose the work may be shifted slightly to the rear far enough to place the front edge of the work against the front guide 116. ln this case the rear marginal portion of the work will overlie the rear guide 122, `and the work will occupy the position indicated convention ally at rc2. According to the width of the work shown, and the position of the front guide 116, the second row of fasteners vill be inserted exactly midway between the front andv rear edges of the work, but the slots 120 in the front guide enable the latter to .be adjusted toward and from the fastener inserting means so that the second row may be inserted, if desired, elsewhere than exactly in the longitudinal median line of the work. rlhe work may now beadvanced again from right to left to insert the second series of fasteners, and in the event that a third row of fasteners is desired the work may be reversed end for `the first hole.
end and placed with its present rear edge against the rear guide so that it will again )y the positi a indicated at ai. The wird row of fasteners will, therefore, be inserted at the saine distance from the `rear ew e as the c. ice between the first row and the present ont ed Assuming that the second row i fastensis been inserted in a line other than the longitudinal median line of the worin a fourth row of fasteners may be inserted by againreturning the work to its starting position vwith its front edge against the front guide according to the position indicated at x2. y Y
The motions of the various instrument-ali-` ties occur substantially follows. The
J eoot will be raised manually in opposition to the applied force of a spring` (not sh wn) preparatory to placing the work in the desired starting position for punching llfhen the presserfoot is released its spring will depress it to clamp the work upon the table. Tae punch initially occupies the position shown in Fig. 3 eX- ceoting' that 'it is raised as shown by Fig. 1. fien the` machine is started, as by depressing a Storti* g treadle to connect the shaft 26 with suitable driving mechanism, thev punch descends to the position shown by Fig. 3, thereby spreading the strands of the fabric to form a hole for the reception of a tener. rlhe presserfoot then rises to free the work for feeding and the punch carrier 30 nieves from right to left, the punch remaining in the work to impartfeeding movement thereto. i'yilhen the punch arrives at a position in registration with the lower-.setting y member the presserfoot descends to clamp the work upon the table, and the punch and upper setting member remain stationary until an eyelet has been inserted clenched. During the work feeding period the lower set rises far enough to insert the spindle 16 through the leading eyeletV in the raceway, and the raceway is then retracted horizontally' tothe rear to leave the eyelet on the spindle and to clear the path for the lower setting member. This condition of the parts is shown by Fig. 4. rlhe lower setting member then continues upwardly to complete the 'setting movement, the spindle lbeing depressed relatively to the lower setting member by the point of the punch, as shown by 5, and the lower setting member rises far enough to insert the barrelofthe eyelet through the worlr and to clench the barrel conjointly with the upper setting member. rihe setting members are then retracted in opposite directions, 'the raceway is advanced to place another eyelet in registration with the spindle 1G, and the carrier 30 is moved to the right to its initial position preparatory to beginning a new cycle of operations.
