HEEL-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 460,175, dated September 29, 1891.

7 Application filed March 6, 1891. Serial No. 383,958. (No model.)

To all whom it may concern:

Be it known that I, NORMAN l/V. BINGHAM, of Somerville, county of Middlesex, State of Massachusetts, have invented an Improve ment in I Ieel-Attaching Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

a The machine herein to be described is adapted to drive staples from the interior of the shoe outwardly into the heel to secure the latter in place and at the same time to drive slugs or nails into the tread of the heel.

The machine to be herein described is an improvement on that represented in United States Patent No. 315,67 5, to which reference may be had.

In this present invention the means employed to drive the staples into the heel are simplified and made stronger and more durable than in the said patent.

One part of my invention comprehends a machine containing a staple-holding box over which the boot or shoe to be heeled may be placed, a series of drivers therein, a nail or slug box to bear against the tread end of the heel, and drivers therein, and means to act uate the said drivers, whereby the staples and the nails or slugs are driven simultaneously into the heel from opposite directions.

Other features of this invention will be hereinafter described, and stated in the claims at the end of this specification.

Figure 1, in front elevation, represents a heeling-machine embodying my invention, the head and parts in it being in section; Fig. 2, a side view thereof partially broken out;

- Fig. 3, an enlargedsectional and broken detail of the staple and nail boxes and the parts contained within them; Fig. 4, an upper side View of the nail or slug driver plate and nailbox; Fig. 5, an under side view of the nail or slug box shown in Fig. 4; Fig. 6, a right-hand end view of the nail or slug box; Fig. 7, a top or plan view of the staple-box over which the boot or shoe is placed, the heel-seat plate forming the top of the staple-box being broken out.

The base or frame A has suitable bearings to sustain a power-shaft A, provided with a balance-wheel A fast and loose pulleys A A and a pinion A as shown by dotted lines. This pinion engages a toothed gear B, fast on the main shaft B, having a crank-pin B embraced by the strap of a connecting-rod B The base has erected upon it two uprights or rods C C, the upper ends of which, reduced or shouldered, are extended through a head C and have screwed upon them suitable nuts C to thus confine the head in position. The head, as best shown in section, Fig. 1, receives a shouldered sleeve 0, on which preferably rests a washer 0, against which bears the lower end of a strong spring 0 the upper end of the said spring, as represented, receiving upon it a washer 0 which in turn is acted upon by suitable adjusting screws or devices 0 the said spring being of great force, so as to yield in case of excessive crushing strain, it having no function to perform as a spring, but merely acting as a stop to prevent upward movement of the sleeve during ordinary work. The sleeve 0 at its inner side is threaded to receive a hollow spindle d. The lower end of the sleeve 0 has fastened upon it a suitable hand-wheel 0 (see Fig. 1,) rotation of the handwheel causing the threads of the sleeve acting upon the threads of the hollow shaft d to raise and lower the same. The lower end of the sleeve d has screwed upon it a block (Z having at its under side a dovetailed groove to receive a dovetailed projection e of a (1 riverplate 6'. (Shown best in Figs. 1, 3, and 4..)

The drlver-plate provided with a series of usual drivers 6 is provided centrally with a hole to receive a bolt 6 which is screwed into a nail or slug box f, provided with suitable holes, as f" (see Fig. 5) for the reception of nails or slugs f Between the driver-plate and the nail or slug box the bolt e is sur rounded with a stiff spiral spring 6 The hollow spindle'd receives within it a rod 11, the lower end of which bears on the head of the bolt 6 the said rod having a collar n, on which rests a spiral spring a the upper end of the spring abutting against a shoulder of the hollow sleeve, the spring a assisting the rod n, acting on the bolt 6 to keep the nailbox separated from the driver-plate e. The nuts 07. on the rod prevent it from dropping out from the spindle when the plate 6' is removed. I

The front end of the nail or slug box f has attached to it a breast-gagef while at its rear side the said box has attached to it by a screw f a spring dog or holder which engages the rear side of the heel, the breast of which is placed against the breast-gage. The breastgage f is provided with two lips or cornergages f 'Normally the lower ends of the drivers 6 stand in the holes f.

The uprights or rods 0 act as guides for a reciprocating cross-head D, to which the connecting-rod B is jointed. This cross-headD is represented as provided with an extension D, having a dovetailed groove to receive the correspondingly-shaped foot of a post D The cross-head has an adjusting or stop screw 0, the rotation of which out and in in an ear 0 determines the position to be occupied by the post, the cross-head also having a locking device r, shown as a cam-lever, pivoted at 10, and having an eccentric or cam-shaped end to engage the foot of the post and hold it in adjusted position during the driving operation. The post is hollow and receives the shank of the staple-driver plate 9, which shank is attached to the post by suitable bolts or screws.

The staple-driver plate carries a-series of staple-drivers g',having their upper ends cut away to leave oblong heads 9?, the ends of the said heads entering guiding-grooves g in the staple-box 9 the heads of the staples s resting upon the heads of the drivers, as represented in Fig. 3. The staple-box g has a shank g which is extended down through the hollow shank of the staple-driver plate, the sa1d shank entering a spring g which is supported within the hollow post, the upper end of the spring g receiving against it an adj ustable collar 9 attached to the said shank, the spring 9* normally acting to keep the staplebox elevated sufficiently above the stapledriver plate to withdraw the stapledrivers sufficiently into the staple-box to receive the heads of the staples and let the latter stand with their' points in the slots at of the heelseat plate 111/, which acts as the top for the staple-box. The holes in the heel-seat plate are oblong, and the heads of the staple-drivers as they act to drive the staples into the heel come up into the said holes and fit them substantially snugly.

In practice the nails or slugs f will be loaded into the nail or slug plate while the latter is off the machine and overturned from the position Fig. 3. The nail-box having been filled with nails or slugs and staples having been put into the staple-box, the operator will place the shoe to be heeled over the staple-box and post and will place the tread end of the heel with its .breast against the breast-gage, making the dog f engage the rear end of the tread-lift. With the heel applied to the nail-box, as stated, the operator will insert the dovetailed projection e into the dovetailed guide of the head or plate attached to the block referred to. Now the machine will be started, causing the rotating of the main shaft, so that it elevates the reciprocating cross-head, and in so doing the heel is at first firmly compressed between the staple-box and the nail-box, and in the further upward movement of the crosshead D the staple-drivers act to force the staples through the usual inner sole and outer sole and into the heel from its seat end substantially to its tread, and during the latter part of the movement of the stapledrivers the nail-box rises about the stationary drivers, compressing the spring 6 the drivers e acting upon the nails or slugs f and driving them from the nail-box into the tread of the heel and through the tread partially into the heel.

I claim 1. In a machine for attaching heels to boots or shoes, the following instrumentalities, viz: a support for the shoeto be heeled, a head C, a hollow rotatable intern allythreaded sleeve 0 therein, a hollow vertically-adjustable spindle contained in the said sleeve, a connected slug-driver plate, a series of slugdrivers, a slug-box, a bolt e a spring located between the plate and box to keep the box separated from the driver-plate to thus retract the drivers and leave place for the slugs, a staple-containing box having slots to receive staples and provided with a seat-plate, and a series of staple-drivers contained in the said staple-box, the combination being and operating substantially as described.
