FRED A. RUMNEY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MACHIN- ERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

FASTENER-SETTING MACHINE.

Application filed August 17, 1912.

T 0 all whom it may concern:

Be it known that I, Finn) A. RUMNEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Fastener-Setting Machines, of which the following description, in con nection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for setting eyelets, hooks or other fasteners in sheet material, such as cloth or leather, and the invention contemplates the provision of a machine whereby such fasteners may be set rapidly and accurately in corsets or similar articles.

In eyeleting corsets much diiiiculty has been experienced in properly guiding the work to the setting tools, as the weight of the garment tends to displace the work between successive setting operations so that the eyelets are likely not to be properly alined with a uniform spread from the edge of the corset. An important feature of the invention consists in the provision of a guiding member having an extended supporting surface and a rib so arranged to support th weight of the garment, preferably by engaging the inner portion of its stiffened edge as it is being fed to the setting tools. By this means the operator is relieved of the necessity of supporting the Work as it is fed through the machine, it being only necessary to see that the stiffened edge of the work runs smoothly through the guiding member.

As herein shown the guiding member comprises a trough-shaped work supporting piece arranged with one wall flush with the edge gage of the machine and the other wall spaced from it by a distance equal to the width of the stiffened edge of the garments to be operated upon. The employment of such a guiding member insures that the work shall be directed to the setting tools in a straight line and that the alinement of the eyelets shall be perfect. As herein shown, the position of the supporting rib is adjustable so ,that the machine may be adapted to handle material with diflerent widths of edge.

An important advantage is derived by mounting the guiding member upon the Specification of Letters Patent.

Serial No. 715,645.

edge gage of the machine as in this way the gulding member will be adjusted simultaneously with the edge gage when it is desired to vary the spread of the fasteners from the edge of the work.

As herein shown the work guiding member is embodied in a Duplex eyeleting machine of the type disclosed in Patent No. 934,066 granted September let, 1909 to G. Goddu, and th combination of a guiding member of the character outlined with such a machine constitutes an important feature of the invention. In a machine of that type, the setting tools are arranged to operate in an oblique path and as the die plate is downwardly inclined, the work has a greater tendency to become displaced than in those machines having a horizontally disposed work plate. The provision of a trough shaped guiding member obviates this diiiiculty by providing a device upon which the work is suspended during the operation of the machine:

Another important feature of the invention consists in a guiding member arranged with its work supporting face disposed below the plane of movement of a work feed ing member together with interposingmeans between the guiding member and the feeding member for elevating the work and directing it to the feeding member and the setting tools. This arrangement of the parts has proved particularly advantageous in practice, not only in causing the work to run evenly and smoothly to the setting tools but in relieving it from undue strain when subjected to the sudden action of the feeding member.

Another feature of the invention relates to an improved form of presser foot by which work of the class in question may be held and directed to the setting tools in an improved manner and all tendency toward slipping away from the edge gage avoided.

In order to permit the work to be fed rapidly it is necessary to insure that each clenched fastener shall be cleared or stripped promptly from the projecting pilot of the upsetting die and to this end the present invention contemplates, as one feature, the provision of a projection located adjacent to the upsetting die in such position that the work is somewhat bent over it by the setting die in the setting operaion. With this construction the work will promptly straighten as soon as released by the setting die and the clenched fastener will be lifted off the pilot so that the work may be moved laterally at once in the feed 1 ing operation.

Still another feature of the invention relates to the construction of the setting tools and consists in the provision of a setting die with a center spindle having a cupped end into which the pilot of the upsetting die is adapted to project when the spindle is forced against it. Advantages of this construction are that the setting die and its center spindle are automatically centered relatively to the upsetting die and that the marginal edge of the hole in which the fastener is to be set is engaged by the cupped end of the spindle so that the loose fiber ends are held compactly until they are covered by the clenched fastener. Another advantage of this construction appears in those cases where the chip cut out by the punch is not removed but remains in place in the work, for in that case the chip will be forced into the cupped end of the spindle where it will stick momentarily when the spindleis retracted so that it will be removed from the work by the spindle.

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 l is a view in perspective of the operating parts of a duplex eyeleter having the presentinvention embodied therein.

As in a machine of Patent No. 93%,066 the frame 2 is prov ided with journals for a horizontal driving shaft l upon which is mounted a driving pulley, not shown, and a series of cams which actuate the various parts of the machine. The movable head or frame 12 carries an oppositely disposed pair of setting dies 14: and oppositely disposed punches 16 which cooperate respectively with the double faced upsetting die 20 and which is rigidly secured in the head 12.

The head'12 is pivotz'illy'mounted by the pin 24; between the forks of an arm of a bell crank lever 26 pivotally mounted in the machine frame. The other arm of the lever 26 carries a cam roller which runs in a cam 8 on the shaft f. The cam 8 acting through the lever 26 serves to move the frame 12 rear-wardly after the punching operation in order to bring the setting dies into the position formerly occupied by the punches. The setting dies and punches are actuated by an oppositely disposed pair of hammer levers 28, one of which is mounted upon the journal pin 30 in the frame of the machine. The other is similarly mounted below the head 12 but is not visible in the views of the machine shown in the drawings. The levers 28 are actuated by the cam 10 acting upon a cam roller journaled in the piece 32 secured to the rear end of one of the levers.

The work is moved transversely between successive setting operations by laterally swinging the frame 12 about its pivot 24c, and this operation is effected by the cam 6 of the shaft l acting through the cam lever 3st and apair of connecting links 36 and 37.

A work plate 38 is mounted in the machine frame adjacent to the die plate 18 when the latter occupies its initial position and upon opposite sides of thework plate are disposed presser feet 40, held yieldingly against the opposite sides of the work plate by springs 42. At their rear ends the springs 42 are secured to a block 44, the forward edges of which constitute edge gages. The work plate 38 has rack teeth 45 cut in its shank and may be adjusted forwardly and rearwardly together with the edge gages and presser feet in order to vary the spacing of the eyelets from the edge of the work.

The work guiding member is formed by a plate having at its upper edge an integral rib 52 notched out at its inner end to receive a portion of the upper edge gage. The rib 52 is secured to the edge gage so that its face extends flush with the face of the edge gage, and the plate 50 i s-held in place by a link which extends from an car 56 on the plate to a stationary arm projecting from the machine frame. The inner face of the rib constitutes in efiect a continuation of the edge gage and by maintaining the edge of the work in contact with this surface the greatest accuracy is secured in directing the work in its movement to setting position. 7

On its lower side the plate 50 is slotted and provided with downwardly projecting clamping bolts 68 arranged to extend through the slotted cars 60 of a rib piece 62.

The upper surface of therib piece 62 eX-' tends above the surface of the supporting plate 50 and is disposed in parallel relation with the fixed rib 52. By loosening nuts 6% on the clamping bolts 58 the rib piece 62 may be adjusted toward or from the fixed rib 52 and the distance between these two ribs may be made to correspond to the width of the stiffened edge of the work in hand.

The position of the work in the guiding member is well illustrated in Fig. 6 from which will be seen that the two stilfened edges of the corset fit into the trough shaped portion of the guiding member with their outer edges in contact with the face of the upper or fixed rib 52 and their lower edges supported by the inner face of the adjustable rib piece 62. When the work is arranged in this position its entire weight is supported by the upper edge and inner face of the rib piece 62 and in operating the machine, it is necessary only to see that both stifi ened edges are kept within the trough shaped guiding member. As the latter is particularly adapted by reason of its characteristic shape to receive these edges, the skill required by the operator is thus reduced to a minimum.

As has been stated above, the feeding movement of the work is produced by swinging the head 12 laterally while the setting dies rcmainin engagement with a clenched eyelet. The extent of the feeding movement is regulated by a controlling lever 39 by which the transmission links 36 and 37 may be maintained more or less effective to transmit the full swing of the cam lever 34. The controlling lever 39 is arranged to move over a perforated plate 41 in which may be set limiting stop pins 13. Upon the lower end of the pivot of the controlling lever 89 is secured a transversely extending arm r31 to which is attached a tension spring 451 tending normally to swing the arm 431 in the direction to hold the controlling lever 39 in its position of maximum spacing as determined by the left stop pin in Fig. 1. Manually controlled means, which in this case comprise the chain l7 and a treadle, not shown, are connected to the arm 431 so as to swing the arm $31 in opposition to the action of the spring 451 in order that the controlling lever 39 may be temporarily swung into a position of close spacing when so desired. This construction, which it is believed has never before been incorporated in a fastener setting machine, is of great advantage when applied to a Duplex machine of the type herein disclosed, for the reason that it enables the operator to eyelet simultaneously both sides of a corset, setting the upper and lower eyelets with a relatively wide spacing and the intermediate eyelets with a relatively close spacing, while at the same time insuring absolutely the correspondence of the spacing in the two sides.

In order to insure that the work shall not slip forwardly away from the edge gages as it is fed through the machine, it has been found advantageous to provide the work plate 38 and presser foot e0 with oppositely disposed ribs inclined rearwardly toward the edge gage. In my prior Patent 1,030,833 is disclosed a work plate provided with ribs of this character, but for handling textile material, it has been found that better results are secured by providing not only the work plate but also the active faces of the presser foot with inclined ribs. As the work is drawn between the two sets of inclined ribs it has imparted to it a tendency to move toward the edge gage, being deflected inwardly from its normal path so as to counteract the tendency toward slipping outwardly.

As already intimated, the feeding operation is effected by swinging the head 12 laterally while the setting dies 14 hold the clenched eyelets against the upsetting die 20 in the die plate 18. At the conclusion of this lateral movement the setting dies 1 t are retracted and the head 12 together with. the die plate 18 is moved transversely in the opposite direction to its initial position. In order to insure that the clenched eyelet shall be promptly disengaged from the projecting pilot of the upsetting die 20 when the setting dies are retracted, the die plate 18 is provided at its end with a thickened portion or bulge 19 which tends to strip the material and the clenched eyelet from the pilot of the upsetting die as soon as the material is released by the setting dies.

In operating upon textile material it is important that the loose fiber ends which are left at the margin of the perforation formed by the punch shall be held compactly together until the eyelet can be clenched upon them, as otherwise the appearance of the work would be marred by loose threads running out from the flange of the eyelet. As herein shown, this defect is obviated by cupping the end of the center spindle 15 of each setting die and making the diameter of the cupped end slightly greater than the diameter of the hole cut by the punch, but slightly less than the diameter of the pilot of the upsetting die. By employing this construction, it will be seen that the margin of each perforation is engaged by the end of the spindle 15 and pressed tightly against the pilot of the upsetting die preliminarily to setting the eyelet, so that there is no possibility of the loose fiber ends being displaced. This action of the center spindle is well shown in Fig. 8.

It sometimes happens that the chip severed by the punch is not removed from the material, but remains in place, and another advantage incident to the construction of the setting spindle 15 is that if a chip is left in place by the punch, it will be forced into the end of the spindle by the pilot of the up- 7 improve the character of the work done by the machine by reason of the fact that it tends toaline itself with the pilot of the upsetting die when forced against its convex end.
