SPECIFICATION forming part of Letters Patent No. 450,755, dated April 21, 1891.

Application tiled March 3l, 1890.

T0 all whom it may concor/1f:

Be it known that l, HUBERT O. HART, residing at Unionville, in the county of llartford and State of Connecticut, have invented certain new and useful Improvements in Ileeling-Machines; 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 te an improvement in that class of machines for heeling boots and shoes in which the nails are first assembled in the to p lift andthe same then forced down upon the body of the heel, through which the nails are thus driven and into the shoe, its leading object being to provide effective means for holding the top lift in its right relation to the nail-holder in which the nails are assembled and in guiding it as it is forced down upon their projecting ends.

lVith this object in view my invention consists in a vertically movable adjustable clamp and in certain details of construction and combinations of parts, as will be hereinafter described, and pointed outin the claims.

In the accompanying drawings, Figure l is a view in front elevation of a heeling-machine embodying my invention, the parts thereof being in the positions due to them before the descent of the presser upon the top lift. Fig. 2 is a similar side view of the machine, the parts being in the same positions. Fig. 3 is a broken View in vertical section showing the clamp and last and the top lift forced down by the presser. Fig. iis a similar view, with the nails assembled in the nailholder and the top lift resting upon their projecting ends in position to be driven down upon them by the presser; and Fig. 5 is a detached plan view of the swinging nail and heel holder.

The frame-work of my machine consists of a stationary horizontal bed-plate A, an upright sleeve B, and two upright rods C C, secured to the bed-plate and united at their upper ends by a cross-piece D, forming a support for the stop E of the awl-stripper M. A heavy plunger F, located within the said sleeve B, is reciprocated, as herein shown, by means of a horizontal shaft G, journaled in hangers l-I l-l, depending below the bed-plate A, be-

fore mentioned, and provided with a wristpin I, operating a lilik I', pivoted to the lower end of the plunger, but, if desired, the shaft may be reeiprocated by hand or in any other suitable way by power.

A horizontal carrier J,sccurcd to the upper end of the plunger, has two arms L and L projecting in opposite directions, and an in- 6o termediate arm L2. The said arms L2 and L', respectively, carry the pressers N and N', each composed of a fiat head and a spindle, the oiiice of the former being to crowd the top lift 'n down upon the nails after the nails 6 5 have been assembled in the nailholder O, and of the latter to drive the top lift and nails 1' down upon the heelbody, at the same time securing the latter to a boot or shoe. The said nail-holder is provided with a num- 7o ber of deep pockets arranged conformably with the final arrangement `of nails in the completed heel and adapted to support the nails with the upper ends of the same proj ecting beyond its upper face, the poeketsbeing shorter than the length of a nail. The said arm L carries the awl-head M and its stripper M, the spindle M2 of the latter extending upward through the awl-headand arm into position for engagement with the 8o adjustable stop E, before mentioned. An anvil O, located directly beneath the said awlhead M and the stripper M thereof, is mounted upon a vertically-adjustable stud forming a part of a carriage O', provided with a man- S5 ual O2 and dovetailed upon the bed-plate A for longitudinal reciprocation thereupon between guides o and o.

The last P of the machine is mounted upon a carriage Il similar in construction and opgo eration to the carriage O, above described. These carriages are like correspondingparts in Patent No. 410,832, granted to me September l0, 1889, and do not need extended eX- planation here.

The nails o' o, which are used in connection with this machine, have shoulders and ends projecting beyond the same a suiicient distance to carry the top lift of a heel-body. The nails are first assembled in the nailro: holder Q, then the top lift is placed upon the projecting ends, as shown by Fig. 4 of the drawings, and iinally the presser Nis brought down upon the top lift and the same forced over the said ends of the nails, which are thus assembled with the top lift. The nails and top lift are then assembled with a heel-body and a boot or shoe upon the last P, after which the presser N is brought down upon the top lift with the effect of forcing the same down upon the heel-body and the nails through the said heel-body and into the boot or shoe. l

For convenience in centering the top lift upon the ends of the nails and to guide the same when being forced down upon the same by the stamper, I have provided a verticallymovable spring-supported clamp adapted to I5 be adjusted to heels of different sizes and combined with the nail-holder Q andthe carriage Q thereof, the said carri age being swivel'ed upon the bed-plate A of the machine by a stud q', and provided with a manual q2, by zo means of which the carriage is swung to bring the nail-holder Q to its norlnal position under the presser N and to withdraw it from that position. The said clamp consists in part of two spring-arms y and y', pivoted at theirlower 2 5 ends in vertical slots respectively formed in the opposite ends of a head R, mounted for vertical movement upon the post g'carrying the nail-holder Q and forming a part of the carriage Q. 3o formed with a bearing-face d made straight to conform to the straight inner edge of the top lift, while the upper end of the arm y is formed with a transverse bearing-finger d', made curved to conform to the curved outer 3 5 edge of the top lift, which is placed between the said upper ends of the two arms. rlhe said head rests upon the upper end of a spiral spring S encircling the part g3, supported upon a part of the carriage Q and exertinga 4o constant tendency to lift the head and so raise the arms into the positions which they occupy in Fig. 4 of the drawings. Athumbscrew d, having a shoulder e formed at its outer end and a corresponding thumb-screw Y d having a similar shoulder e', are respecttively passed through the lower ends of the said arms, so that these shoulders engage with the outer faces thereof, their inner ends being threaded into the opposite ends of the 5o head R, which the arms are normally held away from by means of small spiral springs f and f encircling the inner ends of the screws and interposed between the block and the arms. These set-screws d and d', together 5 5 with set-screws g and g', mounted in the upper ends of the arms and bearing against the nail-holder at opposite points thereupon, are provided for adjusting the spread of the arms to top lifts of different sizes. Normally the 6o upper ende of the arms extend above the nailholder in position to receive a top lift .between them when the same is rested upon the projecting ends of the nails in the holder, the lift being by them held in its right relation to the nails. Now when the presserN descends upon the lift it engages with the upper ends of the arms and forces the same to retire as The upper end of the arm y is rapidly as the lift is crowded down upon the nails. During this time the clamp, or, more properly, the arms, guide the lift and insure its right assemblance with the nails. When the arms retire, as described, the spring S is compressed; but upon the return-stroke of t-he spring it at once restores them to their normal position of readiness to receive another lift. The clamp is thus organized with the nail-holder in the sense that both are mounted upon the same carriage, but the clamp is also movable independently of the nail-holder.

Rubber cushions U U, respectively interposed between the presser N and its arm L2 and the presser N and its arm L', are provided tocompensatefor variations in the thickness of the top lift, whereby the machine is prevented from pounding from that or other causes.

The awl-head M, the stripper M', the stop E, and the anvil O are provided for piercing the heel-bodies preparatory to being placed upon the last to receive the nails, top lift, and to be secured to the boot or shoe. Vhen the awls have passed into the heel, the same is stripped` from them by the stripper M,.the spindle M2 whereof engages with the stop E, supported from the posts C C. In my patent herein referred to the stop is shownv asv supported by an arm secured to the sleeve, in which the vertically-acting plunger is located; but I prefer the construction herein shown as being stronger and as relieving the plunger from all friction so far as the stop is concerned.

To provide for using the machine in making and applying heels with shoulderless nails of the old form, I have furnished it with a heel and nail-holder consisting of an arm X, mounted on the rod C, so as to be swung over and away from the anvil O, and provided at its outer end with a series of vertical nail-holes d2, extending through it and corresponding in arrangement to the arrangement of nails in a heel. The said arm is also provided with four springs b2, secured to its under face and adapted to hold a heel-blank c2 against the same, whereby nails placed in the nail-holes are prevented from dropping through the same. When the arm has been charged with nails and a heel-blank, itV is swung over the anvil O, after which the nails are driven into the heel-blank by means of drivers substituted for the awls inv the awlhead M, the drivers and anvil being set so that the heads or outer ends of the nail will be left projecting from the blank for the attach ment of the top lift on the last P.

The features in which this machine is an improvement over that in the patent referred to are believed to be novel, broadly; and I therefore hold myself at liberty to make such changes and alterations in' the specific construction herein shown as fairly fall within the spirit and scope of my invention.

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

l. In a heeling-machine, the combination, with a nail-holder provided with pockets entering it from its upper face and shorter than the length of a heel-nail, of a movable clamp organized with the nail-holder and normally extending above the upper face thereof to center a top lift above the same, and a presser to depress the clamp and crowd a top lift down over the projecting outer ends of nails inserted into the nail-holder, from which they are afterward withdrawn by means of the top lift, which has thus been attached to them, substantially as described.

2. In a heelingmachine, the combination, with a nail-holder provided with pockets entering it from its upper face and shorter than the length of a heel-nail, of a movable clamp organized with the nail-holder and normally extending above the upper face thereof to center a top lift above the same, a spring to support the clamp in its normally-elevated position of readiness to center a top lift, as described, and a presser to depress the clamp and crowd a top lift down over the projecting outer ends of nails inserted into the pockets of the nail-holder, from which they are afterward withdrawn by the top lift, which has thus been attached to them, substantially as described.

3. In a heeling-machine, the combinatiop, with a nail-holder provided with pockets entering it from its upper face and shorter than the length of a heel-nail, of two verticallyarranged arms, the upper ends whereof are bowed and normally extend above the upper face of the nail-holder, while their lower ends extend below the same, a movable support having the lower ends of the said arms pivotally connected with it, a spring located below the said-support for supporting the said arms in their normal positions, a presser to crowd a top lift down over the projecting outer ends of the nails in the nail-holder, and means for connectingr the upper ends of the arms with the said nail-holder, substantial-ly as described.

4. In a heeling-machine, the combination, with a vertical post, of a naihholder mounted upon the upper end thereof and provided with pockets entering it from its upper face and shorter than the length of a nail, a ver tically-movable head encircling the post below the nailholder, two spring-arrns pivoted at their lower ends to the said head and normally extending above the upper face of tho nail-holder and bowed at their upper ends to clamp a top lift and centerit over the same, a spring for supporting the head, and hence the arms, set-screws extending through the said arms at their upper and lower ends and co-operating with the nail-holder and the movable head to adjust the position and tension of the arms, and a presser to crowd a top lift down upon the projecting Outer ends of nails inserted into the pockets in the nailholder, from which the nails are then withdrawn by the top liftwhich has thus been attached to them, substantially as described.
