i IMPROVEMENT IN MACHINES FOR NAILING HEELS vI0 BOOTS AND SHOES.

To aM ywhom, it may concern,.--

Be it known that I, Gnonen W. ELLIS, of

Lynn, in the'county of Essex and State of knife and the parts immediately connected therewith; Fig. 6, a view of aheel-blank, as prepared for nailing on.

The heets, before. they are applied to the boots by my machine, are built up of lifts cut into a form 'approximating that which they are to have in the heel by dies, and temporarily secured together in a machine which 'I have invented for the purpose, and for which I have applied for Letters Patent simultaneously with this. In the same machine the holes for the tacks are madeand two or more nails are partly driven into and' through the heel. These nails are left projecting from the top lift, and serve not only to hold the lifts together temporarily, but also as guides by which the heels are properly placed in my present machine, where they are secured to the soles of the boots or shoes. I

To enable others skilled in the art to build and use my machine, I will proceed to describe its construction and operation.

The heel-blank which is to be applied to4 theshoe is represented in Fig. 6. The holes b for the nails having been punched 'and the guide-nails ,a inserted upon the machine before referred to, the nailing-block A is perforated with a series of holes, c, exactly conforming in position wi'th the awl-holes b in the heelblank, and in each of these holesc works a driver, d, the lower end of which rests upon the stationary driver-bed B upon the top of a hollow post, C, rising from the bench E. The nailing-block A is secured to a round rod or bar, I),which passes down through the post C, and between the bed and the block there is a spring, g, which raises the block A tothe Speeiication forming' part of Letters Patent No. 4 l,038, dnfed December 22, 1863.

`proper height, where it is arrested by the pin fin its lower'end coming in contact with the underneath surfaceot' the bench E.y A pinguide, F, rising` from the bed B, enters a corresponding hole in the block A and prevents the latter from turning. Then pressure is applied to the nailing-block, it is forced down uponthe bed, Fig. 2, the spring g. yielding and the drivers rising through the holes in the block A so as just to reach the upper surface of the block.

The knife lever G, which is seen inplan iu Fig. 1, in section in Fig. 2, and in perspective in Fig. 4, has a long slot, H. in its center, of a ,width that will `just accommodate the post C within it, so that the lever may turn freely round this post and at the same time have a considerable range of motion in the direction of its length.

The motions ot' the knife lever are governed as fol1ows:'.l`he knife l1 (seen in Fig. 2 in the act of shaving the heel) is formed so as to give the proper curve to the heel, and is secured to the knife-head lr, and has a prolongation, or tailpiece, m, which rests against the nailingblock A. The head 7.'y has two bearin gs or pivots, n, which slide in slots l in the knife-block I, and is forced uptoward the heel, Figs. 1, 2, and 5, by the spring p', The knife is thus allowed to vibrate on its pivots n and to move longitudinally in the slots l.

Above the knife is a fender, s', which rests against the upper leather w and protects it from being cut by the operation of shaving the heel.

The knife-block I slides upon dovetailed ways q on the knifecarriage K, and is secured in position thereon by screws 'i'. Down from this carriage projects a post, L, which fits closely, but-turns freely, in the hole M, Fig. 4. The post terminates in an elongated or double pin s, which tits snugly, but slides freely, in a curved groove, 0, upon the upper surface of the bench E. The curve of the groove O corresponds, generally, with that of the nailingblock A, but will allo-w this block to be Varied sufflciently for all the different sizes of heels that may be required.

The knife h is adjusted by means ofthe screws r, so that. its edge 2 shall be in a vertical plane, passing through the center of the `post L and pin s.

Thepost la ispasseddown through theholeM, and the knil'elever G is turned so that the elmgated pin s will enter the slot() at the pointV,Fig.l,aml as the leveris carried around the pin moves in the direction of its arrow, and as it moves it turns the .carriage K and knife-block, so as to canse the/knife blade vconstantly to make a tangent to the bed B and llock A. The knite l1J is adjusted b v means ofthe screws r, so that its edge 2 shall bein a vertical planel'iassing through the center ofthe post L, and thns the edge of the knife is always kept in the proper cutting position.

In operating the machine, the boot. or shoe, after having been soled, and'while it is--yet upon the last, has its heel secured to it by -nails and shaved, as will be .presently eX- plained. In the machine represented in the accompanying drawings only the rear portion ofthe shoe is shown, Fignfl, and the follower It takes the place of the last. In the great majority of cases, however, the shoe will be heeled before the last is withdrawn.

InFig. 2, T is the sole, which may be. se-

cured to the-insole l and upper leather 110 by pegs, or in any ordinary way. The followerR is attached to the lower end of a rod or bar, U, which slides up and down in bearings V, attached to an arm, X, projecting from the standard Z, rising from the bench E. The bar II isoperated by the eccentric N upon Athe enfl of the shaft P, which runs through the center ofthe arm X. y v

Operation: When not in operation the. nailing-block'is elevated a4 short distance above the. bed B, as seen in Fig. 8, and the drivers d are then sutliciently far below the mouths ofthe holes c to permit a nail to be dropped into each of the holes, except those which come opposite to the guidenails a', Fig. 6.

The nails being thus dropped into the holes with their points uppermost, the heel-blankis 4placed upon the nailing-block, the guide-nails c being placed in their proper holes a2, into which, as before stated, no nails were placed. lhese guide-nails thus serve the purpose of instantly placing the heel-blank in the proper position, so that each hole in the block shall correspond with a hole in the heel. The shoe is. now placed upon the heel, Fig. 2, a proper guide or` gage, projecting' from some stationary part ofthe machine, arresting the shoe in the right positionwith respect4 to the nailingblock A. This gage is not shown uponthe drawings, as such instruments are common in a great variety of machines and net d no further description. The shaft I sturned, and the follower R, (or the last if the latterv has not been withdraw n from the shoes,) together with the shoe,V heel, andthe nailing-block A, is forced down until the latter bears upon the stationary bed While this is taking place the drivers have forced the nails up into thc holes in the heel-blink, or a portion of them,

through the sole and insole and against the bottomlof the follower R', (orofthe 12st,) which is iron plated, to' rivet them and secure the heel firmly, the-guide-nails a., Fig. 6, being at the Sametime drive-n. One of the nails is seen at y, Fig. 2, riveted'against the follower. The descent of the follower (or of the last) is graduated with reference. to the thickness of the heel, so that the latter may be submit- A ted to a great pressure, not only that it may be thus nailed and retained in a solid and com pressed state, but also that it may be shaved while underpressure, which operation is performed as follows:

Starting with the knife-levcrin thel position represented in red in Fig. 1, and moving this lever in the direction of its arrow, the knife commences to ont upon the corner e ofthe heel, and is carried round until it has shaved the entire heel,the tail m ot' the ,knife resting against t'ie nailing-block A, and the fender z against the upper leather of the shoe, as already dcscribed, and thus the block A andthe upper leather serve as guides for the knife, while the fender prevents the knigt'e-edgc from coming in contact with the upper leather.

For certain work I propose to secure the sole and heel temporarily together inthe machine before mentioned; which makes the holes for the nails, the guide-nails being of sufficient length to penetrate pa'rtly into the sole. The

sole and heel are then shaved and securedtogether in my present machine, and before bef ing secured to the shoe.

The heel andthe portion of the sole to which it is attached are then secured to the shoeby six or more nails driven into holes left vacant for the purpose, and clinched upon an ironplated last. In suchcase the nailing-block and the follower R will serve as guide for theknife, v 'the fender resting against the edge ofthe follower. lhis method of shaving the heel and sole before they are secured to the shoe gives a much better opportunity of finishing,r the rand than where the heel issha-ved afterit I is secured to the shoe. Any other method or machinery other 'than that described above may be employed for the purposeof depressing the follower R or the last.` at the proper time.

These details, however, form no part of my present invention, and need not be further particularized. It is necessary, however, that the machine be of sutlicient strength and the .power sufficiently great to compressA the heel with great force before it is shaved.

In a machine for operatin g with heels of different heights a different knife will be required for each height of heel in order that the fender may. bear upon the extreme bottom of the. up-

per leather, which is technically called the topdge, as.seen in Fig. 2. Or the same knife may be used for heels of different heights; but in such case the fender must be made adjustable upon the knife and he secured by screws thereto.

In order that the inside of the boots may be concave to correspond with the convexity of the foot at the-heel-it is customary in building up heels to employ what is called a split lift.7

By the use of my machine this concave form is 'by the compression of the leather. It would, however, be manifestly of no avail thus to shape .enabled to operateupe'n heels ofdift'erent sizes with the single stationary'groove O'by simply l by which the top of the heel is made concave.

given to the heel without the necessity of resorting to the split lift, as follows: The fol-- lower, R, or the last, is made convex to correspend to theshape of the foot, and the heel is subjected to sufficient pressure in the. machine to produce the requisite concavity of the sole the heel if it were again to be released from pressure before being permanently secured in shape.- This is. accomplished 'by driving the nails While the heel is under pressure.' "It is thus held bythe nails in the shape in -which it is compressed by the. machine. It is evident, however, that heels built up with a split lift may equally Well be nailed and shaved upon this machine. By shaving the heel while un der pressure a :much cleaner and better out can be made.

I-t will be perceived that by the employment of the springp behind the shaving-knife I am changing the nailing-block A. By this means the machine is greatly simplified.

What I claim", and desire'lo secure by Letters Patent, isi- 1. In.combination -With the follower it,

placed inside of the shoe, the nailingblocks i A B, so arranged with regard thereto and to the shoe as that the nails shall be driven from GEO. ELLIS.
