1O refe 'ence characters on the drawings indiproved machine of the duplex type which may be run at high speed with little inerand which shall be powerful and accurate in its operation.
An important feature of the invention consists in a double-ended tubular punch arred to be disposed between the two s of material in which the fasteners ac to be set, in such manner that the material mav be perforated by being forced upon :ite ends of the punch. As herein he double-ended punch has conpsetting surfaces formed thereon against which the eyelet barrels are clenched. This construction embodies for the first time 5 of the duplex type the comr punch and upsetting tool which used heretofore with great success gelet setting machines, such for as that of Letters Patent of the l States No. 1,228,768, granted June 5, upon my prior application. Another feature of the invention consists 'e punching plate having suended transversely in the direction red so that the location of the cooperatpunching tool may be varied while ren... within the range of the plate as the extent of feeding movement is changed. h construction is advantageous in that e'minates the necessity for transversely ring one of the punching members, as he case with a punch and die construcin, and also obviates the difficulty heretofore encountered in preserving an accurate alinement of the members.
Another feature of the invention consists in u crk guiding means arranged for adjustment to correspond to the variable initial positions occupied by the feeding member when adjusted for different lengths of feed. is herein shown the double-ended punch is utilized to feed the work, being operated by spacing mechanism controlled by a hand lever. The work guiding means are connected to this lever and so moved by it as to occupy a predetermined relation to the punch regardless of its initial position. The operation of presenting the work properly to the machine is thus facilitated and made uniform for all spacings of the feed.

The setdies are then retracted andthe work stripped from the ends of the tool it? so that the latter may he returned to its initial position in readiness for a new cycle or 019 era'tions. i 5 7 Themachine frame 2 is provided with journals for a main shaft one end a driving pulley engaged or disengaged with respect to the shaft 20 through clutch mechanism of any suitable character. shown herein, but other details of the clutch mechanism are omitted for the sake of clearness since they formno part of the present invention. The frame is provided with an upwardly extending yoke-shaped portion l,
in which are mounted the upper operating levers which will be presently described, and with. two forwardly extending heads 6 and 8 in'which are formed longitudinal bearings for the plungers of the punching plates and setting dies.
i i toolholder a2, best shown in Fig. 6,
' is detachably secured to an arm d8 extending torwardly'ftrom a sleeve 56 journaled to oscillate upon a shaft52 lIlOllIlt-BCl'lfi a stationary portlon of the mac'hme frame.
. Near its outer end the tool holder 42 is pro vided with a socket to receive the punching andnpsetting tool 40. This tool is best shown in Figs. 2 to 4: and/Sand comprises a double-ended tubular punchprovi'ded witl'r an annular upsetting surface 41 at the base 7 of each punching portion. It is also provided with a transversely extending opening e3 through which may be discharged the punchings which are forced inwardly through the bore oi the tubular punches. The tool 40 is retainedinthe tool holder 42 by a screw 44: threaded into the end of? the tool holder as shown in Fig. Sand entering a socket in one side of the tool tO. The tool holder is tapered at its outer end and provided with a. spring U-shapedstripping device t6. Each arm of the stripping device upper, presented on opposite sides to a dour 2O carryingupon 3 whlch may be- Aa treadle rod 16- is.

The toolholder 422 is oscillated to feed the work, as will presently appeaiyby mechanism which will now be described. The sleeve above mentioned is provided at its lower end with an outwardly extending arm 54; which is pivotally connected to link 56. The link as is in turn connected to a second link 58 pivotally mounted by a pin 60 on one end ola reciprocatory carriage 62. The carriage '62 isarranged to move from front to rear in guideways formed in the machine frame and is provided with downwardly extending arms55 which embrace an operating cam been the shaft 20. This mechanism is best shown 1n Fig. 6 from winch it will be apparent that the re ciprocatory motion of the "carriage 62 is transmitted through the mechanism above 0 described to the tool holder 42 as an oscillatory movement.
The extent of. the feeding movement transmitted to theitool holder LQis regulated by a radius link 6d connected to the pivotal point of the links 56 and58 and having a normally stationary but adjustable point of connection. with the machine frame.
:shown in Fig. 7 V the radius link is connect-ed by a stud .65 to. a movable member- 67 arranged to swing about the axis of its shaft 69 journaled in the machine fume. 'Th'e member 6? is provided wit-ha spacing lever handle (53 which is arranged to swing over a stationary segment plate 61 on the machine frame and to be held in any desired adjusted position by pins set in the segmeat plate. f it will be noted that. when the lever 63 is set in the position shown in Fig.
"5 the path of movement of the connection between the links 56 and 58 will coincide in its general direction with the direction of I movement oi the reciprocatory carriage 62 so that. substantially th entire movement of the latter. will be eiiective in swinging the tool holder and relatively long feeding;
movements willresult. When it is desired 7 to decrease the-extent otfeeding movement, thelever 63 is swungtoward the frontot' the machine thereby carrying the stud 65 to such a, position that ,the'path oi. the point oil" pivotal connection between the links 56 and 58 is guided in a direction extending transversely with respect to the movement of the carriage 62 so that only a small coinponent oi? its movement is et fective to feed the work. I r y In this movement of the spacing lever 63 the links 56 and 58 will be somewhat'moved and the initial position of the tool holder 4:2 will be correspondingly shifted. .In the I feeding movement, however, the tool holder will be brought. always atthe end of its :movement to position the tool e0 in the same place, viz., in alinement with the setting v dies. The feeding movement of the punching tool therefore takes place between a variable but predetermined initial position and an invariable final position.
In order that the spacing lever 63 may be swung by treadle connections without stopping the machine the shaft 69 is provided at its lower end with an outwardly extending arm 59 to which a treadle chain is connected. A spring 57 anchored to a pin on the frame and connected to a portion of the member 67 tends normally to hold the spacing lever 63 at one limit of its movement and the action of this spring is opposed when the treadle connections just described are operated.
The punching operation is effected by simultaneously forcing the two pieces of material upon the ends of the punching tool 40. This is effected by a pair of oppositely disposed punching plates 70 which are carried respectively by plungers 72 mounted for reciprocation in bearings in the stationary heads 6 and 8 of the machine frame. The punching plates 70 have sufficient punching area to include the entire range of adjustment as to the punching position of the double-ended punching tool 10. The punching plates are provided with recesses through which may pass the setting dies 100. hen the punching plates are operated the work is forced upon the opposite ends of the punching tool 40. and the arms of the stripper e 6 are sprung by the work. The punching plates are then slightly retracted to re lieve their pressure upon the punching tool and the feeding operation then takes place. During this operation the work is held upon the ends of the punching tool by the plates 70 and the arms of. the stripper remain flexed during the feeding operation and also until the setting dies have been operated to engage the work. The punching plates 70 prevent both arms of the stripper from throwing the work off from the punching tool until the setting operation has taken place. 7
Each plunger 72 is provided at-its outer end with head 73 having an open socket to receive one end of a connecting link 74. The head 73 is provided with an opening to receive a stud projecting from the hub of the link The links '74 are similarly shaped at both ends. and they connect the plungers with operating levers 7 6 which have sockets similar to those of the heads 73. A leaf spring is secured toeach lever 76 and arranged to bear upon the adjoining hub of the link 74 to retain it in its socket in the lever '76. lVhen it is desired for any reason to remove a link Tel it is necessary only to loosen the spring 75 and to swing it from the end of the link whereupon the link may he slipped out of its sockets.
The upper operating lever 7 6 is supported by a pin 78 mounted in the upper part of the yoke portion A of the machine frame. An adjustable eccentric bushing is interposed between the pin and the lever as shown in Fig. 9 and affords convenient means for adjusting the pressure of the punching plate oper-- ated by this lever. The lower operating lever 76 is correspondingly mounted upon a pin 7 9 which is set in the machine frame and illustrated in detail in Fig. 12. As shown in this figure the frame is provided at one side with an outwardly extending boss 12 which affords an extended bearing for a bushing 110. The eccentric bushing 77 upon which the lower lever 7 6 is mounted is provided on its outer end with a recess adapted to receive a corresponding projection on the inner end of the sleeve 80. The sleeve 80 is provided with a head disposed outside the machine frame andprovided with openings for a spanner wrench. The eccentric bushing 77 may be turned for purposes of adjustment through the medium of the sleeve 80 the latter being maintained in adjusted shaft.
The rear ends of the operating levers 76 are connected by a pairof toggle links 82 and 83. At their common pivotal point the toggle links are connected to a slide 84 arranged for movement in a "stationary guide- Way formed in a portion 10 of the machine frame. A link 86 is also connected to the common pivotal point ofthe toggle links 82 and 83 and this in turn is connected to the upper end of a cam lever 88 journaled to oscillate upon atransverse shaft 22, extending across the rear part of the machine frame. The lever 88 is shaped to embrace an operating cam 90 secured upon the main shaft 20. The cam 90 is so shaped asto swing the lever 88 rearwardly to straighten the toggle links 82 and 83 so as to advance the punching plates 70 to effect the punching operation. The lever 88 is then moved slightly farther toward the rear thus breaking the toggle links upon the other side of the center line and slightly retracting the punchingplates 70. The punching plates are maintained in thispositionwhile the feeding operation takes place and finally the lever 88 is moved forwardly into the position shown in Fig. 9 and brought to rest with the punching plates retracted.
The setting dies 100 are arranged for movement in bearingsin the heads 6 and 8 parallel to and at one side of the punching plate plungers 70. Each of the setting dies is connected at its outer end to a link 102,
similar to the links 74 above described, and these in turn are connected respectively to the forward end of an upper bell cranklever 106 and a lower bell crank lever 104. vThe upper lever 106 is mounted upon an eccentric bushing on'pin 78 and adjacent to the position by a nut 81 on the end of the.
short spacing. The guide plate 120 verse opening to e ect the. punchings upper operating lever for the punching plate plunger. The lower operating lever 10 1 is mounted upon an adjustable eccentric bushing 10? onpin T9,; the bushing being connected to an adjusting sleeve 110 similar to' prior application above identified. It has been foundparticularly satisfactory inimparting to the dies the movements necessary to take eyelets tromthe raceways and, upon the withdrawal. of the raceways, to advance the eyelet for the setting operation.
The work passes to the tool holder 4C2.
from work guiding means in which the work is preliminarily presented and which will now be described. A guide plate 120 is detachably mounted in an arml122 extending forwardly from a sleeve 12% journaled upon the shaft 52 beneath the sleeve 50 which carries the tool holder. The arm 122 extends upwardly so that the guide plate 120 is located in. the same plane as and parallel to the tool holder 4.2. A. gage block 126 is adjuE-itably mounted on the guide plate 120 and providedwith a pair or" presser feet each comprising a spring 128 and an end portion 130. The presser feet are similar in construction and disposed upon the upper and lower-surfaces oi: the guide plate 120.
They are flared outwardly at their forward ends to facllltate the insertion of the work.
Each of the springs 128 isprovided with a U-shaped section to accommodatethe adj acent portion of the punching plate 70. The guide plate 120 is provided on opposite faces with grooves extending parallel to the direction of feed so that, in handling uppers inwhich lacing hooks have already been set,
the endmost hooks may enter said. gmoves and be moved close up to the punching tool 40 when it is desired to set an eyelet with a I is also provided. with a transversely erteudingstud 132 arranged to be projected in to the trans 43 of the punching tool and which have been forced into it. This construction and its manner of operation will be clear from Fig. 4.
.As already pointed out, it is desirable to locate the work guiding means in the same relation to the tool holder 12 regardless of.
the adjustedposition of the latter. To this end the sleeve 12.4: which carries the work guiding means is provided with an outwardly extending arm 1341 which carries a roller 136 at its end. The roller 136 is received in a segmental cam slot formed in the member -67 of the spacing mechanism. The cam slot is so shaped asto oscillate the arm 134-. and the work guiding means, when the spacing lever is moved sutliciently to compensate for any movement of the tool holder produced in adj usting the extent of the feed. Thus, whatever the initial position of the tool holder 1-2, the'work guiding meanswill be found close beside it so that the presentation oi? the work will take place in precisely the same manner although at a somewhat diilerent position in the machine.
The eyelets are supplied to the setting dies from a hopper 14h). thin nigh a pair of raceways 141-1. The raceways are arranged to be mo ved into delivering position. in alinement with the settin g d1es anc, after delivering the eyelets, the racewaysv are moved. outwardly to an inoperative pos1t1on. To this end the hopper andraceways are mounted upon an oscillating bracket 1 16 provrdedwnh clamping means 148., to oscillate between pivot pointed screws 160 and 161 each of which is threaded into an eccentric bushing 150. The bushings 150 are adj ustably retained in a pair 01" cars ld'l'and 149 projecting rearwardly from the machine frame. The bracxet 146 has an outwardly extending arm 162 connected througha universal joint to an adjustable link 166 in turn is connected through another universal joint to a cam lever 168 arranged to os illate upon the shaft 22 above mentioned. The cam lever'168 is shaped to embrace an operating cam 170 .ta'st upon the main shaft 2t). The cam 170 is shaped to oscillate the lever 168 andthe r aceways in the proper timed relation to the setting dies 100.
Tn ordertemporarily to'suspend the supply of eyelets means are provided for turning the eccentric bushing 150 to shift the bracket 1% bodily so; as to carry the race ways to an inoperative position. To this end the upper bushing 150 is connected to downwardly e:-:tend1ng' arm 152 and the lowerbushing member (not shown) is similarly connected toJan upwardly extending arm 154;. The arms 152 and 154: are secured together so that an equal movement of the linishings is insured. The lower arm 15% is provided with an outwardly extending lug through which extends a rod 164. A spring 156 surrounds the rod 164-. and bears against the hi on the arm 152 tins normall maintaining the bushings 150 in a position to render the raceways operative. hen it is desiredto move the raceways to inoperative position it is necessary merely to pull the rod 164- :torwardly compressing the spring 156 and turning the'bushings 150 as above outlined. I j
The bracket 1% is mounted which The operation of the machine will be apparent from the foregoing description, but may be briefly summarized follows: Having adjusted the tool holder 42- and the guide plate 120 to determine the spacin of eyelets by means of the lever 63, the operator presents the two pieces of work upon opposite sides of the guide plate 120 with the point which the first eyelets are to be set in line with the double-entice punching tool 40. The yielding presser feet 130 maintain the work in the relation to the punching tool which is established by the presentation of he work. The initial position of the operative parts of the machine is well shown in Fig. 2. The machine is then. started and the unching plate 72 advanced to force the work upon the opposite ends of the p" 11011- ing tool, the punchings passing into the bore of the tool. This position of the parts is shown in Fig. 3 of the drawings. The punching plates are then slightly retracted and the punching tool 40 is moved transversely into alinement with the setting dies 100, the punching plates serving in the meanwhile to prevent disengagement of the work from the punch. l'lyelets have mean while been delivered to the setting dies and the dies are next operated o force the eyelet barrels through the holes in the worlr and to clench their barrels upon the annular upsetting surfaces about the punching portions of the tool. In this operation the punchings are forced by the die spindles into the transverse bore of the punching tool 4E0. Fig. 4: illustrates the parts of the machine in this position. The setting dies are then retracted and the worlr thrown ed the clenching tool by the stripper The tool holder 42 is then moved toward the right to its initial position and in this movement the pin 132 encounters the punchings and ejects them through the passage At the conclusion of the return movement of the tool holder the machine parts arrive their initial positions in readiness for the repetition of the cycle.
