MACHINE FOR PUNCVHINCS; THE LIFTS OF BOOTrHEELS.

Specification forming part of LettersPatent No. 41,037, dated December 22, i863.

'Zo all whom t mwyconcerit: y

Be it known that I, GEORGE W. ELLIS, of Lynn, in the county of Essex and State otl Massachusetts, have invented an improved machine for'pnnching the lifts of boot-heels and temporarily securing them together, of

which the following is a full, clear, and exact.

. cure the'iifts of heels together and to punch them for the nails which secure them to the boot, and which are, driven by another ma chine for which I have made application for 'Letters Patent simultaneously with this.

In carrying out my invention the llifts are irst cnt out'by dies ot`a"size and form. approximating to that which they are ultimately vto have in the heel. They are` then placed upon a bed, suitably arranged with respect to each other,'and by means of a. follower which is then brought down upon `them they are l forc d down uponthe awls and punched, and

at the same time two or more tacks or headless bench B, or is dovetailed into the same, as

seen in the drawings, so that it may be drawn out from beneath the plunger for the purpose of inserting the work. To this table is secured the awl-block C, from which' rise the awls f, which are to pierce the heel and malte the Above the block C is a bed, D, which is perforated with holes s to :permitJ the passage of the awls through it, and :upon it the lifts which are to form the heel are placed, the smallest lift at the bottom and the largest at the top. The bed D is surrounded by a daring rim, E, which 'arranges the'lifts with respect to each other as they are placed upon the bed, and has projecting down from it a post, F, which is surrounded by a spiral spring, g, the upper end-ofiwhich rests upon the' 'under side of the bed and the lower end upon `,the block C, in which the-awis are secured.

'The post F is passed down through a hole in the block G, and is' allowed a motion up and down to a certain extent, being limited in its upward motion by a pin, i, which is allowed to move in slots up through the bench B and table A, but rests against the bottom of the block C.

In Fig. l the bed D is thrown by the spring g into its highest position, the pin i resting upon the under side of the block G. When in this position, the' bottom of the post F is elevated clear of the bench B, and the table A maybe withdrawn. f

G is a stationary knife, secured to the table A, the edge b of which` is on a level with the top of the bed D. y

I is a plunger, attached to the rod K, that slides in a guide, L, and is moved up and down bythe eccentric M upon a driving-shaft, N, which is operated by suitable power. In the machine represented in the drawings Ithe guide L and shaft N are carried by the standard O, rising from the bench B; but any other suitable arrangement of these and other details forming no part of my invention may be adopted. In the operating machines the shaft N is driven by steam, and makes about tifteenrevolutions per minute.

Attached to the rear ot' the rod Kis a bentA arm, P, which'moves up and down with the rod, and is formed at its lower end, as seen at d, for a purpose that'will be hereinafter ex# bring the bed D from beneath the plunger I,

the lifts Q, Fig. 3, are placed upon the bed D, the smallest at the bottom, the next size above it, and so on, the Hare oftherim E being such as instantly to arrange the iiits Without requiring time or attention on the part of the operator for the purpose. The table A is then Vthe heel. It is evident that the adhesion between the awlsfand the leather will be very great, and thatit would not be practicable to employ a spring, g, of suicient force to withdraw them from the heel. rIo ei'ect thispurpose, and to raise the bed D 'andthe heelblank from ott' the awls, the lower portion, d, of the arm P strikesthe lower end ofthe post F andraises it as the eccentric continues to turn, the-spring g serving only to hold it elevated until the plunger strikes the leather lifts. The spring also holds the bed D up when the table A is withdrawn, Fig. 4. The heel is now shaved upon its forward edge, and the holes for the nails are made; but it is requisite at the same time to secure the lifts temporarily together and to furnish the heel .with guides, by which it'may be properly adapted to the machine before referred to,y

'by which it is secured to the shoe. This 'is eectcd in the following manner: 'Two or more of the awls f are replaced by short drivers, one of whichis seen at n,`-Fig. 3, which plays in the hole n of Fig. 1. Into the holes of the bed D, corresponding to these drivers, are ldropped nails of a sufficient length v to penetrate the lifts and to project about oneeight-h inch, or thereabout, above the top lift.l One of these nails, c, is seen driven in Fig. l5, it having been dropped, point uppermost, in the la-ole n2, before the lifts were placed upon the bed, the driver n being then so low that the point oi the nail is below the upper surface of the. bed l). In the machine by which the heels 'areI applied to the shoes, the edge of the heel is shaved by a knife which )asses round its edge, and to avoid the danger of the nails c interfering with the shaving-knife the drivers a may be inclined inward, so as'to slant the,

ject about one-eighth inch from the upper lift,

and thus serve as a guide by which the blank may be placed 'in the next machine, where the nails are driven and the heel shaved.

The piston I is represented, Fig.v3 as passing down just within the cutting edge of the knife G; but I contemplate in most cases having it project over the knife, the cutting-edge of which works against a strip of solder on the under side of the plunger.

With some work I secure the sole temper rarily to the heel blank at the same time that the latter isv punchedy and tacked together. The rear part of the sole. or that portion covered by the heel, is then secured to the Y,

shoe by the nails which are afterward driven to secure the heel to the sole, a portion of them passing through the upper-leather an l inner sole and clinching upon an ironplatel ast.

At times, also, my machine will be used for preparing heel-blanks that are' to be afterward secured to' the boot from the inside.

VUnder these circumstances the' awl-holes will tion with the bed-I) and plunger 1, operating as set forth, for the purpose specified.

3. In combination with the above, the stationary knife Gr, operating as set forth.

4, The rim E upon the bed D,l for the purpose of arranging the lifts, as set forth.

5, The arm P, attached to the rod K, in combination with the spring g, whereby thc awls are withdrawn and the plunger lelevated and held up, as set forth,
