EYELETlNG-IVIACHINE.

SPEC-IFIGATION forming part of Letters Patent No. 701,262, dated May 27, 1902.

Application filed April 6| 1901.

T all whom, t mln/y concern:

Be it knownthat I, PERLEY; R. GLASS, of Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvementin Eyeleting-Machines, (Case A,) of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The present invention relates to an eyeleting-machine, and is embodied in a machine for punching the holes for a number of eyelets and setting a nulnber of eyelets at one operation.

The machine herein shown for the purpose of illustrating the invention is substantially like that shown in a prior United States patent granted to me May'7, 1901, No. 673,814, the invention relating mainly to improvezo ments in the construction and arrangement i of the gages for the material, 85e. A

The invention further relates to nove means for forcing the material onto the punches after the material is perforated, so that the ends of the punches may protrude beyond the surface of the material to guide the eyelets, which are set or clenched by means of suitable setting devices coperating with clenching-shoulders formed around the punches.

It is usually desirable when eyelets are to be set in shoe-uppers to spread the eyeletsthat is to say, to set them in a line which is not parallel with the edge of the upper-the eyelet nearest the toe portion standing farther away from the edge than the eyelet which is adjacent to the studs. In eyeleting the right and left members of an upper, therefore, it is necessary that the stock should be gaged differently during the successive operations in order to obtain a proper spread, and one of the objects of this invention is to provide the machine with a gage which will be automatically shifted at the end of each cycle of operations, so that the right and left members of an upper can be consecutively eyeleted on the samemachine, the gage being in the right position for each of the said operations. The gage is arranged to exo tend some distance along the edge of the up- Serial Nol 54,657. (No model.)

per, and is pivotally supported at a point substantially midway between the ends of the gangs of tools and arranged to be shifted n `on said pivotal support, so that irst one end of the gage and then therother end will be moved laterally toward the said tools. The two positions of the gage are determined by 4 stops, which may advantageously be adjustable, and the gage is connected with a traveling member of the machine, which is so ar- 6c ranged as to shift the gage at the end of each cycle of operations, the gage remaining stationary during the operation until after the i eyelets have been clenched in the material and the tools have become separated therefrom. At the end of each cycle of operations, therefore, the gageis left in theproper position to cooperate with the other member of the upper without care or attention on the part of the operator.

The machine is further provided with gages to determine the endwise position of the upper, there being two such gages-one for each member of the upper-the position of which upper of course has to be shifted between the operations on the two members thereof. These gages are adjustable, so as to be accommodated to uppers of different sizes or styles, and in order that the adjustment may be readily effected and may be uniform in all cases the gages are provided with a common adjusting device which coperates wit-h both, so that the two end gages always bear the same relation to the edge gage, thus insuring uniformity in the eyeleting of the two members of the upper.

A further feature of the invention consists in an end gage of novel construction, the said gage consisting of a member adapted to cooperate with one of the lacingstuds in cases where the lacing-studs have been previously set, this insuring the proper relation between the studs and the eyelets on both members of the upper.

The machine embodying the invention is shown as provided with a set of tools each of which has atubular punching portion and an annular clenching portion, the punching portion lirst cooperating with an anvil to perforate the material, and the clenching portion f j engagement with the punches after the holes have been made, and also that the said punches may project beyond the surface of the material to guide the eyelets into the holes, the machine is provided with novel means for forcing the material toward the clenching portions of the punches as soon as the holesare made, the-anvil-carrier being providedWithanengagingmemberyieldingly supported in such a position as to project above the anvil, the saidr member having openings to permit the punches to coperate with the anvil. The said member has sufficient bearing-surface to support the material when the punches come in contact therewith, and will yield as the punches and anvils come-together until the punches have actually perforated the material, leaving the said material free to move with relation to the punches, the yielding'member then forcing the material on the punches as is desired.

Figure l is a side elevation of a machine embodying the invention. Fig. 2 is a partial top plan view of the same, illustrating the construction of the gage-operating mechanism. Fig. 3 is a partial top plan view showing the end gages adapted to coact with previously-inserted lacing-studs; and Figs. 4, 5, and 6 details on an enlarged scale showing the means for forcing the material toward the clenching portions of the punches after Y the punching operation is completed.

Referring to Fig. 1, the machine is shown as provided with a gang of punches a., mounted in an overhanging arm or projection A2, which forms part of the frame A, the said punches being directly over a supportingtable A3, which is provided With an opening for a vertically-reciprocating anvil member Z) and a gang of vertically-reciprocatin g setting devices c, which are provided with yielding fingers c2 to pick up the eyelets from suitable raceways formed in a feed-chute D in the ordinary way. In the operation of the machine the anvil member b iirst rises, carrying the material up into engagement with the tubular cutting portions of the punches a to perform the punching operation, then receding and leaving the material on the said tubular 'cutting portions and moving laterally in its downward movement, so as not to interfere with the subsequent upward movement of the setting devices c, which complete the eyeleting operation.

In order properly to spread the eyelets, the table A3 is provided with a gage d, which is shown as pivotally supported at cl2, the point of pivotal supportl being substantially midway between the ends of the gangs of tools, the said gage being adapted to swing on said support between adjustable stops e, which `so that the gage d is free to move.

vonaea are adapted to limit the said swinging movement.

The gage CZ is sufficiently long to lie in contact with the material for some distance along the edge thereof, and as it swings onits pivot with relation to the gangs of tools it will cause the said edge of the material to stand at an angle to the gangs of tools, the apex of said angle being at one end or the other in accordance with the position of the said gage, so as to spread the eyelets along either member of the upper, one position being necessary for one member and the other position necessary for the other member, since the position of the upper must be reversed between successive operations in order to set eyelets in both members consecutively.

To produce the shifting of the gage CZ automatically, the said gage is herein shown as connected by means of a link (Z3 with an e1- boW-lever d4, pivotally connected With the frame A, one member of said elbow-lever being operated upon by a reciprocating arm d5, which is arranged to move in one direction at the end of a cycle of operations and in the other direction at the end of the next cycle of operations.- As herein shown, the said arm d5 is acted upon by a cam-groove d?, which receives a cam-roll d at the end of the said arm, and the said cam-groove is shown as formed in a rotating disk (Z5, mounted on a counter-shaft d and provided with gear-teeth d10, the said teeth intermeshing with the teeth of a gear B2 on the main shaft B in the ratio of two to one, the said cam-groove thus making only one-half a revolution to each one revolution of the main shaft.

The cam-groove di, as shown in Fig. l, is of such shape as to produce a movement ofthe arm (Z5 during the last part of the rotation of the main shaft B, such movement therefore taking place after the setting devices c have receded far enough to release the material, This leaves the gage standing in the other position ready for the other member of the upper, the shape of the cam-groove being such as to produce no movement of the gage until the next eyeleting operation has been completed.

In order to compensate for the various adjustments, the elbow-lever d4 is yieldingly connected with the arm (Z5, as by springs d, the said springs acting both ways to seat the gage d against one or the other of the stops e regardless of the position of the said stops, it being unnecessary, therefore, to vary the eX- tent of movement of the arm d5 if the positions of the stops e are varied or the gage cl as a whole adjusted with relation to the gangs of tools, as by the adjustable connections A4 of the table A3.

In order to gage the endwise position of uppers in which lacing-studs have previously been set, the machine may be provided in accordance with the invention with end gages which consist of members f, mounted in the IOO IIC

table, so as to engage one of the lacing-studs, as indicated in dotted lines, Fig. 3, the upper being inverted during the eyeleting operation, so that the studs Vproject downward. The machine is provided with two of such gages, one for each member of the upper, and in order that these gages may be easily adjusted for use with different sizes or styles of uppers and also that a symmetrical adjustment may be secured, so that both members of the upper will be gaged alike, the gages are provided with a common adjusting device adapted to operate equally on both.

As shown in Fig. 3, each gage f is provided with a slide or carrier f2, the said carriers being provided with rack-teeth f3, both of which sets of rack-teeth `are adapted to be acted upon by a pinion f4, provided with an actuating member or handle f5. The said rack-teeth f3 are arranged on opposite sides of the said pinion f4 so that the rotation thereof in either direction will produce movements of both gages f corresponding to each other, but in opposite directions, so that both gages at once will be moved equal distances toward or Vfromthe gangs of tools, as is necessary for the proper gaging of each upper during each of the successive operations thereon.

The handle f5 may be arranged to travel along a scale member f, provided with retaining notches f7, the distance between which may be arranged to accommodate any degree of adjustment required. A similar common adjusting device may be applied to end gages adapted to cooperate with the top edge of the upper in case the` eyelets are set before the uppers have been provided with lacing-studs. Such a construction is shown in Figs. 1 and 2, in which the end gages fw, which are arranged at the corners of the table A3, are mounted in guides and provided with rack-teeth fio, intermeshing with pinions f4", each pinion having connected therewith a crank or radial projection f, which cranks are connected together by means of a link flz, so that if one of the pinions is moved a corresponding movement is imparted to the other.

As shown in Fig. 2, one of the pinions may be provided with ahandle f5,1novable along a suitable scale member fo, and provided with retaining-notchesf". While this form of actuator is simple and convenient of operation, it is obvious that any other suitable form of actuator may be employed, while the connection between the gages may be modified, the object of the invention being to provide the gages flo with means for equal adjustment, so that the difficulty of getting both gages adjusted in such a way as to get the same results with the two members of an upper is obviated.

The means for forcing the material up onto thepunches ct after the holes are made are illustrated in Figs. 4, 5, and 6, the anvil member b being shown as provided with a set of anvils b2, one for each punch a, the said anvils projecting upward from the surface of the said anvil member. The said anvil member is further provided with a yielding support b3, which normally stands,` as shown, above the said anvil member and is provided with openings b4, which are sufficiently large to surround the anvils b2, so as to permit the depression of the said support b3 to a point substantially level with the surfaces of the anvils. The said support is held in its normal position by means of springs b5which are of such strength that they willyield when the material engages the punches c in the upward movement of the anvil member, so that the anvils b2 are forced upward against the material interposed between `them and the punches until the anvils and punches come together to completely perforate the material, which is then free to move upward along the punches, as indicated in Fig. 5. The springs are, however, sufciently strong to overcome the resistance afforded by the tapered outer surfaces of the punch, so that as soon as the material is actually perforated it will be forced upward onto the punches, remaining there with the punches protruding and ready to receive the eyelets from the clenching devices c when they move upward after the anvil member has traveled out `of the way. K

The yielding support b3 may be secured in the anvil member b in any suitable or usual way, being herein shown as provided with supporting-rods h6, extending through vertical openings in the anvilmember b and pro' vided with heads D7 to maintain the support h3 in its proper normal position. The springs b5 are shown as spiral springs held in position by means of pins bs, extending through suitable openings in the anvil member b and` affording additional guides for the support b5, as well as retaining members for the springs which are interposed between the lower sur# face of said support and the upper surface of the member b.

l. In an eyeleting-machine provided with a gang of punches and a gang of setting devices, a gage adjacent to the punches and setting devices, and having an elongated gaging portion to extend some distance along the edge of the material, said gage being movable around an axis midway between `the ends of the gangs of tools; and means for automatically moving said gage on said axis after each setting operation, as set forth.
