FASTENER-SETTING MACHINE.

Application filed April 10, 1916.

in the uppers of boots or shoes or other sheet material. j

An object of the invention is to provide improved work feeding mechanism. for fastener setting machines wherein the feeding tool is mounted in a swinging head. In such machines it is customary to straighten the feeding path by shifting the feedingtool radially during the movement of the head so that the work may be advanced in a substantially straight path instead of a curved path which would be objectionable, particularly in setting fasteners with a wide spacing. The mechanism of my invention accomplishes the desired results in a new and improved manner. To this end a feature of the invention consists in mechanism responsive to the swinging movement of the head for shifting the head to straighten the feeding path of the tool.

As herein shown the supporting means for the head includes an eccentric journal and connections are provided between the head and the journal so that the journal is turned to shift the head bodily in the desired direction when the head is swung in the feeding operation. Such a construction presents the advantages of simplicity and accuracy of operation without objectionably increasing the weight of the moving parts and consequently the inertia of the machine.

Other features of the invention relate more particularly to machines for handling two or more layers of sheet material, as for example, the two quarters of an upper, or the lining and outer part of an upper when treated separately as in setting invisible eyelets. In this connection an important feature of the invention consists in a sta- Specification of Letters Patent.

'tionary intermediate plate arranged to sup port, between two layers of sheet material, the upsetting or punching dies which co operate with the movable punching and eyelet inserting tools. This construction, certain features of which are equally applicable to either single or duplex machines, is advantageous because it eliminates the tendency to displace the work sometimes caused by the movement of an intermediate plate in case the latter encounters any obstruction such, for example, as a tongue which, in certain styles of boots, it is customary to Another advantage incident to this construction is that the work may be punched and eyelets set at a point much closer to a line of stitching than has been possible in machines wherein an intermediate plate is moved perpendicularly to the line of fasteners. In the illustrative construction, the punching and setting tools traverse a single path with respect to'the co-acting member, the tubular punch cutting against the central part of anannular upsetting die in the 3133- tionary plate.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which,

Figure 1 is a view in perspective of the operative instrumentalities of the machine;

Figs. 2, .3, 4: and 5 illustrate successive steps in the punching, setting and feeding operations;

The invention is herein illustrated as em bodied in an eyeleting machine of the type disclosed in l nited t tates Patent l lo. illlltlti. granted t epteinhcr t l, 1.00%). on an application 01" G. (,itttitlll. although it is not limited in its application to the or to any particular type or fastener setting machine. Those parts of the machine not herein illus trated may be considered as similar to the corresponding parts of the machine of said patent. The punching and setting tools as in the machine of the patent, are n'ioun'tcd to slide longitudinall in bearings formed in the upper and lower branches of a forked head 6 pivotally connected means of a spindle 5 to one arm of a bell crank lever l. The lever t is mounted upon a po tion of the stationary machine frame 2 in a manner to be presently described. The oppositely disposed punches 8 are mounted in parallel e lation to and in the rear or the oppo.

disposed eyelet sets 10 and are SUCCQSSlvolf. operated by hannner levers 12, one oi? which shown in Fig. l and the other ot which corresponds in shape but is concealed iiiu'nn view in the figures of the presentdram These hannncr levers are operated in the proper timed relation by care on the main shaft 1% of the machine as fully exp ained in the patent above identified.

The punches 8 and sets 10 cooperate successively with a combined punching and no setting die 16 mounted near the outer edge of a tin stationary plate 18. The plate 1k. is constructed and arranged to be insertec between the two layers of work operated upon by the machine. one layer being guided across its upper surface and the other layer across its lower surface. Normally stationary but yielding presser feet 20 disposed upon opposite sides 01? the plate 18 serve to hold the work in position upon the surfaces of the plate 18 but permit it to be advanced in the feeding operation. The plate 18 has a rearwardy extending shank which is stationarily but adjustably secured to the machine frame 2. The prcsser feet 20 are s ipported by a block which clamped upon the shank of the stationary plate 18 and which also carries edge which extend transversely along ie rear oi? the plate and serve to determine the distance etween the line ot eyelets and the edge of the work.

in initial position the head 6 is located so that the punches 8 are disposed in alineinent with the combined punching and upsetting die member 16 and the punches are operated by the hammer levers while the head remains in this pos ion. The punches have an interior diameter slightly larger than the center part of the member 16 and when operated cut agai st the curved annular surface of said center part. The head ti is then shifted rearwardly to bring the sets 10 into the position pr-vi usly occupied by the punches. This movement of the head toward the rear is etlected by an oscillation of the bell crank lever 4: under the actuation of a can: it; on the shaft 1%. In this movement the sets are brought into operative relation vit i the hannner levers l2 and the latter are then operated to force the sets toward the stationary u 'isetting die it to insert an eyelet in each layer ot the work.

fitter the setting operation has taken )lace the sets are retracted slightly and the 'l, 6 is moved transvmsely toward the left ffcct the tending operation. This teeda movement of the head is e'li'ec-ted by the rain 28 on the shaft lat acting through a cam lever 30 and a pair of transmission links 32 extending between the forward end of the lever 30 the head 6. A spacing lever 3 is connected to the links 32 in sucl manner as to control the effective movement transmitted to the head 6 and so regulate the oven'ient ot the head 6 tak s place the head about the axis of the spindle and consequently. it there were no other means a ti:'e..iing the movement of the head, the path of the setting dies by which the work is fed would along the are of a. circle described about the axis of the spindle 5 as a center. order to straighten the :t'eedin path ai si: are provided for shifting the head 6 TO its transverse movement. tine specific tori of mechanism for etiec-ting ois movement is herein shown and will now be d "crihed. 'ihe bell crank t which carries the head 6 is mounted to turn about journals 36 formed eccentrically upon the ends at a journal member mounted in hearings in a portion ot the machine :trame see Fi it). At i s upper end an man it) is secured to the journal member 238 and by it the .aid ineinher may be turned and the eccentric journals i thrc v in the proper direction to advance and the head (3 so that the movement of the sets it in a suhstantiallv straightline path. The arm it) is turned bv the movement of the head "6 itself and to this end connected by a link if to a point upon the head at a point between its aXis and the bearing for the sets. it will, thus be seen that the turning of the eccentric journal member is responsive to the swinging more! out of the feeding head 6. verving in amount in accordance with the extent or" the feeding movement and tl us compensating for the rearward niove-nient of the head which would be caused by its move ment about the axis in the absence or" such provision.

The sets 10 are provided with the usual yieldingly mounted center spindles 4J3 which serve first to position eyelets presented from the raceways, not shown, and then to assist in the feeding operation by engaging the barrels of the clenched eyelets while the head 6 is moved transversely. In the feeding movement the ends of the spindles 16 rcmain in engagement with the opposite faces of the stationary plate 18 as shown in Fig. 6. There is therefore no possibility of the work slipping from the feeding tools and the danger of uneven feeding of the two layers of work is so eliminated.

the edge gages 24 and are positioned so as to'bri-ng the points at which the first holes are to be punched into alinement with the combined punching and setting die 16, and consequently into alinement with the oppositely, disposed punches 8. The machine is then started and the punches are. immediately; operated as. shown in Fig. 3 to form a hole in the upper layer and the lower layer 52.0f-the work. It will be noticedthat the punching operations take place independently so that holes of different sizes may he'formed if desired in the two layers of, the work.

. At the. conclusion of the punching operation the hammer levers 12 are retracted, the punches withdrawn and the head "6 shifted rearwardly to bring the sets into alinement with the previously punched holes. It will be noticed that during these steps of the cycle there is no movement of the plate 18 between the two layers of workbut. that this plate,.'the edge gages andithe presser feetall remain stationary. Eyelets are then A presented to the spindles 46 of-the sets 10 by .raceways, not shown, and the sets are then operated by the hammer levers 12 to insert eyelets into the previously formed holes and clench them against the opposite sides of the upsetting die member 16. This step of thecycle is illustrated in Fig. 4.

At the conclusion of the setting'operation the sets are slightly retracted to relieve the pressure upon the stationary upsetting member 16 and the head 6 is moved transversely to feed the work. During this operation the ends of the spindles 46 remain in yielding engagement with the opposite faces ofthe stationary plate 18.and are moved transversely in sliding contact with the surfaces. Figs. 5 and 6 illustrate the machine parts in the positions occupied at theend' of the feedingoperation. During this feeding operation the turning movement of the eccentric journal member 38 throws the head 6 forwardly causing the feeding tools to move along a substantially straight linerpath. At

the conclusion of the feeding operation the sets 10 are retracted and-the parts of the machine returned to their initial positions shown in Fig. 2. V 7

Having thus described my invention, I
