HEEL-BREASTING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 236,148, dated January 4, 1881. Application filed November 5, 1880. (No model.)

' To all whom it may concern:

Be it known that I, MYRON J. FERREN, of Stoneham, county of Middlesex, and State of Massachusetts, have invented a new and useful Improvement in Heel-Breasting Mechanism, of which the following description, in connection with the accompanying drawings, is a specification.

This invention in he'el-breastin g machines consists, among other things, in the combination, with a reciprocating breasting-knife and a presser to bear upon the top-lift end of the heel, of gages to act upon the curved outer portions of the heel, to insure the exact locationofthe heel under the breasting-knife; also, in a breasting-knife and tippingrest or presser, combined with a jack having a jointed or pivoted foot part, and with means to force the jack or presser toward each other and clamp the heel; also, in a breasting-knife and jack to hold a boot or shoe, combined with an adjustable tipping-presser to bear on the heel end and radiallyadjustable gages to bear against the outer portions of the heel being breasted. The adjustable or tipping presser, against which the top-lift of the heel is pressed, and the jointed jack enable the face of the toplift to be placed and held in a position more or less at right angles to the path in which 0 the breasting-knife-travels, so as to slant the heel-breast more or less in either direction from a vertical line intersecting the sole.

Figure lrepresents, in front elevation, a heelbreasting machine embodying my invention;

5 Fig. 2, a vertical central section thereof, the

part of the link joining the treadle and knifecarrying cross-head being shown in elevation; and Fig. 3 is an under-side view, in detail, of the heel-presser or rest-plate, with its attached 4o adjustable heel-guides.

The upright standards or rods to a serve as guides to properly direct the movements of the jack-carrying cross-head b and the knifecarrying cross-head c.

The cross-head b has connected with its lower end a toggle-joint composed of the link d, pivoted to the said cross-head at 2, and the link d, pivoted upon the stationary frame-work e at 3, the two links being pivoted together by a pin, 4, preferably provided with a suitable friction-roller to enter a slot, f, (see Fig. 2,) in

the treadle f This treadle, pivoted at f, is lifted by a spring, f When the roller on the pin 4, during the downward movement of the said lever, reaches the upper end of the slot f, the toggle-joint is straightened and the crosshead b is elevated, forcing the heel 5 of the shoe or boot g, held on the pivoted or rocking foot I) of the jack b snugly up against the presser or rest plate 6, such operation clamping the heel firmly against the rear end of the sole, while the heel-breasting knife Icis brought down to cut or trim the breast of the heel.

The jack 1) is pivoted upon the cross-head Z) at b so that it may be turned forward into the dotted-line position, Fig. 2, to receive or permit the removal from it of a boot or shoe havin g a heel placed thereon, after which the jack is moved back into the position shown in full lines, preparatory to lifting the said jack and cross-head b, as described, by straightening the toggle joint or lever.

The heel-breastin g knife k is adj ustably connected with the knife-carrying cross-head c by screws 0 At the front side of the said crosshead I have added avertically-adjustable gage,

I, held in place by screws Z, the lower end of the said gage acting upon the sole of the boot or shoe in its shank just as the edge of the knife reaches the level of the sole and has fin- 8o ished cutting the heel-breast, the gage preventing the knife from cutting into and injurin g the sole at the front of the breast.

The cross-head c has pivoted to it, at 6, a forked link or yoke, m, the lower cross-rod, m, of which is provided with a hole to receive loosely the upper end, 7, of the link m which, at its lower end, as at W, (see Fig. 2,) is connected with the treadle f. The upper end, 7, of the link m fitted loosely into the cross-rod m, has a pin, 8, extended through it, which acts upon the top of the said cross-rod to depress the link m and cross-head 0 when the foot-treadle is depressed. When the foottreadle f is in its normal position, as shown 5 in dotted lines, Fig. 2, the shoulderlO of the link m rests against the under side of the crossrod m of the link m, and the cross-head c is held up by the springs 0 which are supported at their lower ends upon the ears b of the I00 cross-head b. As thetreadle f is depressed the part 7 of the link m moves freely in the cross-bar m of the link m until the pin 8 strikes the upper side of the said bar, after which further downward movement of the treadle depresses the knife-carryin g cross-head and knife to breast the heel. By the time the pin 8 reaches the cross-bar m the slot in the treadle has straightened the toggle-jointed lever and fully lifted the cross-head b.

The foot b of the last is pivoted at N, so as to rock or tip more or less as the heel is pressed upward against the rest-plate or presser i, such construction being necessa y to permit the foot of the last and the upper part of the heel, connected with the sole of the boot or shoe, to adapt itself to the face of the rest or presser i, which may be more or less inclined from a true horizontal position to insure the desired slant of the heel-breast; or, by having the face of the rest or presser in true horizontal position, the heel-breast may be made vertical.

The rest-plate 1', having a flat under face, is rounded at its upper side to fit into a concavity of the movable yoke n, where it is adjustably held by a screw, 12, extended through an elongated slot of the yoke, so that the said screw can move in the said slot as the rest-plate or presser i is turned or tipped from a true horizontal position by means of the tipping-screw 13 at the lower end of the yoke, its end acting upon the rear end, 14, of the said rest-plate or presser, as in Fi 2.

The yoke n has ears 'n, which surround the upper ends of the standards a, there being a sufiieient space between the inner walls of the said ears or sleeves and the standards to receive spiral springs n (see left of Fig. 1,) which, at their lower ends, are seated within the said sleeves. while their upper ends are acted upon by the nuts M, the movement of the nuts pressing the springs and causing them to hold down the yoke n and its connected rest-plate or presser with more or less force, but in a yielding manner, so as to obviate too great compression of the heel or strain upon the machine.

I have connected with the underside of the rest-plate or presser i a series of radially-adjustable gages, 1), their adjustment being secured by means ot'scrcws 16, extended through slots in the said gages. These gages may be adjusted radially to place them in the proper curved line to adapt their faces to the contour of the trimmed or other heel of any desired shape or size. These gages act as stops for the heel, and so locate it, when thejack is turned up into the full-line position, Fig. 2, as to insure a straight transverse cut at the breast of the heel and at the desired distance from the rear of the heel. These gages may be set for a heel of a given size, and after that every heel breasted with the gages in such position will be of exactly the same size. In practice I prefer to use about five of these gages in each machine.

I claim- 1. In a heel-breasting machine, a reciprocating breasting knife or blade, combined with a rest or presser to bear upon the toplift end of the heel, and with gages to act upon the curved outer sides of the heel, substantially as described.

2. In a heel-breasting machine, a reciprocating breasting knife or blade, k, and a tipping rest or presser, 1', combined with a jack having a jointed or pivoted foot part, and with means to force the jack and presser toward each other to clamp the heel while it is being breasted.

3. In a heel-breasting machine, the breasting-knife and jack to hold the boot or shoe, combined with the tipping adjustable presser or rest-plate i, and radially-adjnstable gages p, to act upon the outer edges of the heel, substantially as described.

4. In a heelbreasting machine, the restplate '5, combined with the movable cross-head or slide I), and the pivoted jack, having its foot partjointed thereto, substantially as described.

5. In a heel-breasting machine, the crosshead and jack, pivoted thereon at its upper end, the toggle-jointed lever connected with the said slide, and the slotted treadle to actuate the said toggle-lever, combined with a knife carrying crosshead, a knife thereon, and links connecting the said treadle, the treadle acting to first elevate the cross-head and jack against the rest-plate, and then to depress the link and knife-carrying cross-head to breast the heel, substantially as described.

6. In a heel-breasting machine, the rest or presser and its yoke and springs to hold it down in a yielding manner, combined with avertieally-movable jack to hold the boot or shoe, whereby the presser and jack adapt themselves to the heel being breasted.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MYRON J. FERREN.
