IMPROVEMENT lN MCHINES FOR HEELING BQCTS. i

The Schedule referred. to in these Letters Patent and-making part oi the same.

To all whom it may concern.: v

-Be it known that we, TIMOTHY K. REED, of East Bridgewater, and ARzA B. KEITH, of North Bridgewater, all in the county of Plymouth and State of Massachusetts, have jointly invented au Improvement in Heeling Boots and shoes; and we do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specitication is a description of our invention snihcien't to enable those skilled in xthe art to practice it.

The invention relates to a method of locating heels in the manufacture of boots and shoes, so as to co1'- rectly place each heel to be nailed with reference to the rear or counter part of the boot or shoe.

Generally, the heel to be nailed is located by the eye et' the workman, and, as the edge of the heel is rough or untrimmed, it is impossible to accurately place all heels by 'the eye alone. The object of our invention is to ohviate the necessity of such eye location, by employing a device which shall positively or mechani ally-place the heel accurately with reference tothe counter or rear part of the boot or shoe.

To accomplish this we combine with two jaws which grasp 'the counter adjacent tothe soles (or the rear part of the sole it' it has been trimmed) a heel-plate or holder, which receives the heel and presents it to the sole, this heel-plate having an openingl corresponding to the size and shape of the top or finishing-lift of the heel, which lift is cut by a die to or approximately to its ultimate shape, and having provision for vertical I movement to carry it toward or from the shoe. It is in the combination with calipering-jaws of a heelholder, so formed as to receive the upper heel-lift or.

a pattern-plate applied thereto, and capable of such movement as to locate the heel upon the shoe centrally with respect i'o said jaws, and to the opposite surfaces grasped thereby, that ourinvention primarily consists.

The drawing represents a machine embodying our improvements.

A shows the machine in side elevation.

B is an end view of it.

O, a plan.

Dr shows the invention in connection with a nailingjack, upon which the last and shoe are supported.

a denotes the shoe.

1) the sole. v

d, the rear or heel part of the sole.

e e e f are the heel-formingiifts, f being the top lift.

At D the shoe is shown as placed upon a last, mounted upon a nailing-jack, and it is in connection with such a machine that oui-'invention is particularly intended for use'.

gg denote two jaws or caliper-arms, the rear end h of one of which has projecting from it a horizontal pin, t', upon which the-rear end k of the other slides, saidy pin passing through a stationary head-piece, l.

In an` extension of this heady-piece a screw-shaft, a, is journaled at its center, and so as to rotate without end movement, the opposite ends of this shaft having, respectively, right and left-hand screw-threads, which pass through the sha-nhs of the opposite jaws g y, working in nut-threads in said shanks, the shaft having at one end a handle, o, by which to turn it, both jaws being equally and simultaneously separated from or drawn toward cach other by rotation of the shaft, and having such equal and simultaneous movementrelative to the center line of the head-piece.

The boot or shoe to be heeled is placed upon a suitable last, andthe jaws g gbeing sufficiently separated they are hroughtto the opposite sides ofthe counter, and the screw-shaft is then turned so as to bring them cach jaw preferably enteringthe rand or crease, between the heel part (of the sole and the counter.

Beneathv the jaws an adjustable gauge, q, maybe. used, for positioning the jaws for boots and shoes ot' different shapes or sizes, the shank of this gauge sliding in apiece projecting down from the head l, and being fixed in position by a screw, lr.

Upon the headqiiece lis a central bed-plate, s, bearing a slide-plate, t, having guide-lips u projecting from it, enabling it to slide forward or back, a screw-pin, v, extending through a slot, w, serving to confine the slide-plate in position.

At the inner end of this plate is ahorizontal hingepin, x, upon which is mounted a vertically-swinging plate, y, at the front end of which is a heel-plate or heel-guide, z, preferably hinged to the front edge of the plate y. p

This guide is made with an opening corresponding to the size and form of the upper and nished or shaped heel-lift f, or of a pattern-plate, which may be, fastened to the lifts.

The longitudinal center of this-opening corresponds t exactly with the center line between the caliper-jaws g g, and this corresponding position it maintains under any change of position which it may be made to asthe heel-plate, such heel mustbe centrally located with reference to the rear end or heel part of the shoe body. 4

In commencing to usethe device for any size or style of boot or shoe the caliper-jaws are first made sole. The gauge q is then moved forward until it touches the counter, and is then conned by its screw r. The upper lift of the heel, or the heel-pattern, is `then placed in the heel-plate, andthe heel is brought tioned as to the length of the shoe by the eye of the up snn l vagainst the shoe, the upper inner ed e of gy e g sume, so that when a heel is presented tothe shoe by to accurately embrace the counter just beneath the down to the shoe. The irst heel is carefully posi operator, the plate t being loosened so that. it can be freely slid, and, when in correct positiomthe screw v is tightened. After this every heel is quickly located, without disturbance of the gauge q or plate t, by calipering the'counter, placing the heel in the heel-plate, and then bringing the heel down to the shoe.

The position ot' the gauge q and plate t relatively to the jaws g g may be at first determined by trial upon a finished boot or shoe and the heel thereof, instead of' by the eye, and instead of using the counter as the calipering-gnide the heel part of thel sole may be l'irstinished and used as the caliperug-snrface.

When the heel has been located as described, two or more nails are partially driven to secure the heel to the sole, and then the heel-plate is swung up and the nailing is;continued, the jaws being first removed or not, as may be desirable.

After nailing, the shoe is ready for the trimming ot the heel in a heehtrimming machine, and as the heel has been located with reference to the count-er, and

the nail-holes are punohed'eqni-distant from the edge of the located heel-lift g, it follows that, if the paring of a heel-holding or presenting device, for accurately locating the heel to be nailed, substantially as described. y i l Executed October 24, A.- D. 1870.
