SHOE-REPAIRING MACHINERY.

.Appliication filed July '7,

To all whom it may concern:

Be it known that I, WILLIAM L. RoAoH, a citizen of the United States of America, and resident of Corinth, in the county of Aloorn and State of Mississippi, have invented certain new and useful Improvements in Shoe- Repairing Machinery, of which the follow ing is a specification.

This invention relates to shoe repairing machinery and particularly to stapling machines, the said invention having relation more particularly to a machine adapted for repairing turned-sole shoes, the said invention having for its object the Provision of novel means for securing a new sole to the upper of a shoe of the character indicated without making it necessary to turn the shoe during the operation.

A further object of this invention is to produce a staple driving device having means for supporting a shoe by applying the shoe to a rest or support, the said support being inserted in the shoe and so proportioned as to permit manipulation of the shoe with relation to the support so that the said shoe will be supported at the edges, from within and whereby a securing device such as a staple may be caused to penetrate the sole and upper for securing them together.

A. still further object of this invention is to produce means for swivelingly or rotatably mounting the shoe supporting element in order that it may be moved with relation to the clenching or driving element and permit an adjustment which will cause the staple to be driven with the points of the staple arranged in spaced relation and parallel with the edge of the shoe or sole.

A still further object of this inventon is to provide novel means for operating the plunger or hammer which co-acts with the support and an anvil carrled thereby.

lVith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will behad to the accompanying drawing forming part of this specification wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a View in elevation Specification of Letters Patent.

In these drawings 10 denotes a base having-a standard or column ,11 rising therefrom and terminating in a head 12 which is preferably tubular in order: that it may form a guide for the plunger rod 13 which is slidable through the lower end 14 of the head and which has on its lower end a plunger or hammer 15. A collar 16 is secured on the plunger rod by a fastening 17 such as a pin, and a spring 18 is interposed between the said collar and the end of the head, the said spring serving to urge the rod upwardly to its normal position. There is an anti-friction roller 19 rotatably mounted on the upper end of the plunger rod and it is engaged by an operating cam 20 mounted between its ends on apivot 21 which extends through the supports such as cars 22:

on the upper end of the head, and the upper end of the cam has an operating element 23 connected to it which element is preferably a flexible member such as agcable, wire or the like, run over a pulley 24k and having any suitable means such as a treadle for exerting pull on the flexible member for oscillat ing the cam and causing it to depress the plunger rod to bring the. plunger into operative relation with the work which may be held in proper relation to it by means which will be presently explained.

In so far as an operative device is concerned, the member could be pulled by hand, but I prefer to supply some mechanical means, as has been stated, such as a treadle, which can "be operated to pull the member 23 through the aperture 2-5 of the base.

The work supporting element comprises what may be termed ahorn 26 having ash-ank 27 rotatably mounted in an aperture 28 of the base, and the said shank may have a recess 29 adapted to receive the end of a screw which may be threaded through the base for holding the horn at the position of adjustment shown in Fig. 1, although preferably it will be sufiicient to mount the horn or support in the manner indicated for rotary motion so that the support may be moved after a shoe has been applied to it for bringing parts or surfaces of the sole of the shoe under the hammer or plunger for the purpose of driving the shanks of the staple through the upper and the sole for attaching them together.

The horn is of the gooseneck type so that the anvil supporting portion 30 is approximatelyv horizontal, this arrangement being, so far as the applicant knows, a preferable construction in that the shoe is held in better position with relation to the plunger and with relation to the staple for a securing device. The portion 30 of the support near its outerend has a seat 31 of somewhat irregular contour and preferably of such configuration as to accommmodate and receive an anvil 32 of the configuration of the anvil shown in Fig. 5, asit has been found in practice that such an anvil has sufiicient bearing surface for the looped portion of a staple, and the wings or flanges 33 of the anvil can have their sides engaged by the staple guides 34: which are of simple construction yet efficient in operation. The guides as well asthe staple are, of course accommodated by the aperture 31 in the member 30, and the said staple guides are slidable in the said opening as will presently appear. V

The outer end of that portion 30 of the horn has a transversely disposed aperture 35, v and the anvil has an aperture 36 adapted to plunger or hammer, the spring exerts pres register with it in orderthat a securing pin 37 may be employed for holding the anvil stationary. A spring38 has its inner end anchored to the horizontally disposed portion of the horn as at 33 at a point remote from its end and the said spring has a portion which projects under and supports the staple guides'normally as shown in Fig.3, but when the plunger or hammer descends and the staples are driven into'the work and are being clenched, the staple guides are 1; V pressed downwardly to create a clearance 1'01 tot the shoulder 50 with the lug 49, as Wlll.

{ be apparent from an inspection of the drawthe operation. Upon the elevation of th sure to restore the staple guides to norma position when they are in position to receive and hold another staple for a repetitiono the operation. The staple guides thus form seats or holders for retaining the staple against dislodgment with relation to they anvil while the shoe is being manipulated;

to position the shoe in proper relation to the staple and this means has been eiiective and satisfactory and comparatively inexpensive.

The plunger or hammer 15 has its operat-- ing face provided with a clenching groove 39 which serves to bend the ends of the staple for performing the clenching operation,

and by reason of this construction, the horn position of The plunger rod has a hammer head 46 on its lower end and a springretaining head 4;? on its upper end, there being a spring 4.8 interposed between the upper head and the inner wall of the apertured boss for holding the plunger normally retracted.

The head 43 has an internal lug 49 adapted to engage a shoulder 50 on the cam 51, the said cam being 'oscillatably mounted'in the head by means'of the pivot 52. The cam is operated under the influence of the flexible member 53 which may be in the nature of chain operating over a pulley 54 and leading to a treadle 55 by which pull is exerted on the cam. The treadle is held nor-.

mally elevated by the spring 56 anchored to the treadle and to the frame of the machine respectively.

In this embodiment of the invention, the horn 57 has a trunnion pin 58 secured to it by a set screw 59, and the said trunnion pin is rotatably mounted in the frame as shown at 60.

The work supporting end 61 of the horn is slightly different from the form heretofore described, but its configuration is well disclosed in Fig. 8, it being understood that the side supporting end. is to be supplied with an anvil andwith staple guides of the form heretoforeshown. however, the spring 62 is held under the staple guides and is anchored to the horn by means of a clip 63 which may be of any appropriate construction. The movement of the cam in this modified construction is, of

course, limited by reason of the engagement In a shoe repairing machine, a base having standard terminating in a hollow head, a lunger rod slidable in the said head, a colar secured to the plunger rod within the head, means interposed between the collar and the end 01 the head for holding the In this modification, V
