HEELlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,832, dated September 10, 1889.

Application filed March 13,1889. Serial No. 303,107. (No model.)

To aZZ whom it may concern:

Be it known that I, HUBERT C. HART, residing at Unionville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Machines for Making and Applying Heels to Boots and Shoes; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in machines for making and attaching heels to boots and shoes, the object being to produce a machine which shall be simple, durable, easily operated, efficient, and have a large capacity for work.

With these ends in view my invention consists in a machine having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view, partly in vertical section and partly in elevation, of a machine embodying my invention. Fig. 2 is a similar view taken from the opposite side of the machine. Fig. 3 is an enlarged plan view of the machine with v the cross-head and its attachments removed.

Fig. 4 is-a detached enlarged reverse plan view of the awl-head and awls. Fig. 5 is a similarview of the awl-stripper. Fig. 6 is a detached enlarged plan view of the nailholder. Fig. 7 is a sectional view thereof. Fig. 8 is a view in side elevation of a nail. Fig. 9 is a detached enlarged plan view of the heel-gage, and Fig. 10 is a view thereof in side elevation.

As herein shown, the machine is adapted to be operated by hand and foot power; but, if desired, it may be constructed to be run by steam or any other power.

The machine is provided with a horizontal cross-head or carrier A, removably secured to the upper end of a short, heavy, upright shaft B, adapted to be vertically reciprocated in a sleeve D, standing up from the bed E of the machine, the lower end of the said shaft being secured to a horizontal lever F, having one end pivoted to a hanger G, depending from j the machine-bed and its other end connected by an adjustable rod H to a crank-arm I, secured to a shaft J, mounted in the standard K of the machine and carrying a hand-lever L, provided with an adjustable weight M, which is employed to throw additional power into the end of the stroke of the hand-lever L. One end of the said cross-head is provided with a vertical cylindrical socket or bore N, with a horizontal set-screw 0, arranged to enter such socket, and with a seat P, which is formed upon its lower face. A circular or disk-shaped awl-head Q is provided with a hollow shank R, and upon its opposite face with a series of awls 0, arranged in the outline of a boot or shoe heel, and so as to pierce a heel-body suitably to the introduction thereinto of the binding-nails, which, as herein shown, each consist of a binding end S, a wearing end T, and a collar U, interposed between such ends. (See Fig. 8.) This awlhead is applied to the cross-head by the insertion of its hollow shank into the said socket N from the lower end thereof, being held in place by the set-screw O, which is turned to impinge against it.

An awl-stripper consisting of a spindle V and a disk W, having a series of holes or perforations X, corresponding in arrangement with the awls C, is applied to the machine, so that its spindle passes up through and projects above the stem R, and so that the holes in its disk receive the awls C, which play through them and project below its lower face. The projecting upper end of the spindle, which is provided with two nuts Y Y, holding the stripper in place, is engaged by a set-screw Z, mountedin the outer end of a stop-arm A, secured to the upper end of a stationary rod B, passing through an opening C, formed in the cross-head and screwed in the upper end of the sleeve D. The said awl-head and stripper are located directly above a heelblock D, having a short shank E and two fingers F and G, the former carrying two set-screws H and the latter carrying one setscrew H, the said set-screws being employed to set the heel-block for holding the heels in right position under the awl-head. The block ismounted in the upper end of a verticallyadjustable post I, the threaded lower end whereof enters a carriage J, adjustably se ICO cured to the bed of the machine by a setscrew K and adjustable thereon toward and away from the sleeve D. A vertical slot L, formed in the lower end of the post, receives a screw M, mounted in the carriage and holds the post from turning when it is being raised and lowered by means of the nut N, forming a part of the carriage, which is gaged in its longitudinal adjustment by a horizontal setscrew 0. The opposite end of the crosshead has a recess P formed in its lower face to receive the short shank Q, of the nailinghead R, which is secured in place by a setscrew S, mounted in the cross-head. An iron last T, having a shank U, is mounted thereby in the upper end of a post V, the lower end whereof is threaded into a longitudinally-movable carriage \V, mounted upon the bed of the machine upon the opposite side of the sleeve D thereof from the carriage J, already described. The said carriage V is dovetailed between two plates X and Y, which are bolted to the bed of the machine. A manual Z, secured to the carriage \V, is provided for moving it back and forth away from and under the nailing-block before mentioned. The lower end of the post- V is provided with a vertical slot A receivin g a screw 13*, mounted in the carriage and preventing the post from rotating while it is being vertieally adjusted by means of the nut 0 which forms a part of the carriage. A set-screwD horizontally mounted in the extreme inner end of the carriage,gages its inward movement under the nailing-head. Spring-clamps E E having curved cross-pieces at their upper ends, are secured to the carriage \V in position to stand up on opposite sides of the last and prevent the shoe from lateral displacement thereon. A heel-gage, consisting of a slotted upright F (see Figs. 9 and 10) and a horizontally-adjustable block G is secured to the sleeve D by means of a screw H in position for holding the heel against endwise displacement on the last, the'block Gr being horizontally adjustable toward and away from the last on the angled upright, which is vertically ad justable on the sleeve D. A presser-arm 1 provided with a manual J is mounted so as to swing in a horizontal plane upon. the shouldered upper end of a shaft K having bearing in a vertical sleeve U, (see Fig. 2,) formed integral with the plate X, before mentioned. The lower end of the shaft is connected by a rod M. with a horizontal foot-lever N the inner end whereof is pivoted to the standard K of the machine. This presscr-arm co-operates with a nail-holder 0 (see Figs. 6 and 7,) having a series of holes or pockets P arranged in the form of a heel, and together adapted to receive as many nails as are required for a heel, the nails being supported by their collars so that their wearing ends or heads will extend above the face of the nailholder for a sufficient distance to have the top lift of a heel secured to them. The said nail-holder is removably attached to the shouldered upper end of a post Q having its lower end threaded and mounted in the bed of the machine to one side of the sleeve D and opposite the hand-lever L, two nuts R being provided for raising and lowering it, so as to adjust the nail-holder in its vertical relation to the presser-arm, which is normally held above the holder by means of a spring 8*, (see Fig. 2,) located within the standard Kand pressing against the lower face of the foot-lever N The plate Y before mentioned is provided with an ear T (see Fig. offsetting into the vertical plane in which the handlever moves, and carries a set-screw U forming an adjustable stop for such lever.

Having now described the construction of my improved machine, I will proceed to describe the mode of operatingit. An imperferatc heel-body is first placed on the heel-block in right position under the awl-hcad. The hand-lever is now operated to pull down the cross-head, whereby the awls are caused to pierce the heel-bod v, forming the required nail-holes therein. As the awls penetrate the heel-body, the stripper engages with the upper face thereof and is stopped. After this the continued descent of the cross-head leaves the upper end of the stripper-stem projecting therefrom. \Vhen, now, the hand lever is thrown back to lift the cross-head, the upper end of the stem of the stripper is engaged with the adj ustable screw mounted in the stoparm, and holds the stripper against upward movement with the awls, which lift the heelbody against the lower face of the stripper, which then becomes a point of purchase for pulling the awls out of the heelbody, which drops back upon the heel-block when the awls are entirely free from it. The pierced heel-body is w assembled with a boot or shoe upon the last, together with a top lift which has had the nails required for the heel rigidly assembled with it by means of the nail-holder and the presscr-ai'm. \Vhen the nail-block comes down upon the top lift, it forces the same down upon the heel-body and at the same time forces the nails through the heelbody, binding the several lifts thereof together and. firmlysecuring it to the boot or shoe, which results from the upsetting of the ends of the nails upon the iron last. It will be understood that every time the cross-head is brought down for piercing a heel-body it will also secure a previous]y-pierecd heel body and a top lift to a boot or shoe, the two operations being effected sinmltaneously with my machine, which therefore has a large capacity for work. To assemble the nails with a top lift, the nail-holder is filled with nails and a top lift placed upon their pro ecting outer or wearing ends or heads. The presserarm is then swung around over the nail-holder and brought down by pressure upon the footlever upon the top lift, which is forced down upon the nails with which itis thus combined, so that when it is removed from the nailholder the nails come with it and are readily inserted all at once into the holes of a heelbody, which is thus filled with nails more readily than under the old process of putting the nails in one by one by hand.

I would have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
