HEEL-SEAT AND COUNTER BEATING MACHINE.

SPECIFICATION forming part of Letters Patent No.. 731,168, dated .T une 16, 1903.

Application filed June 16. 1902.

To all whom t Wray concern:

Be it known that I, CLARENCE L. EATON, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York,have invented certain new and useful Improvements in Heel-Seat and Counter Beating Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in boot and shoe machinery, and more particularly to a machine for beating the heelseat and counter of a lasted shoe.

In the process of lasting a shoe the upper must be pulled and stretched so as to giveit the shape of the last. The several thicknesses of leather and cloth prevent perfect smoothness of the counter being attained in this preliminary operation, the result often being that wrinkles or ridges appear upon the shoe. Also on account of the stiffening for the counter it is difficult to make the heel part ofthe shoe conform to the shape of the last. Durin g this operation the counter-seam is roughened and distended, due to the pulling about of the leather, and it is necessary to remedy this defect before the shoe can be put on sale.

It is easily seen that Where the counter, counter-stiffener, stays, and linings are all doubled over together and tacked in place the heelseat will be left very rough-Eso much so that considerable beating is required to iatten it preparatory to applying the outsole'and completing the shoe.

The obj ect of the present invention is to provide a machine for rapidly and accurately beating the counter and its seam and also the heel-seat while the boot or shoe remains on the last, wherebythe counter is given a smooth and symmetrical appearance, the seam is beaten neatly Hush with the surface of the leather, and the heel-seat is leveled.

To the above ends the present invention consists of the devices and combinations of devices, which willnow be described, and particularly pointed out in the claims. p

The presentinvention is illustrated in the accompanying drawings, in which- Figure l shows a vertical section taken through the center of my improved machine Serial No. 111.343. (Nomodel.)

and showing a shoe in position to be operated upon. Fig.v 2 is a plan View of a plungeroperating cam. AFig. 3 is a perspective view of one of the yokes for carrying a cam-roll and adapted to connect the plungers and cams.

Similar reference characters will be used throughout the specification and drawings to designate corresponding parts.

The machine comprises a suitable frame formed of a suitable base A and horizontal4 secured thereto or formed integral therewithy a disk B3, provided with the cam-groove b3. The bevel-gear and cam are for operating the heel-seat-beatin g plunger.

The heel-seat plunger C is arranged vertically mounted. to both rotate and reciprocate in bearings a3 and a4 in the arms A3 and A4 of the frame. A bevel-gear D, meshing with bevel-gearBz, is connected with the plunger by means of a spline c2, engaging in a way C3, formed in the plunger, thereby enabling the' gear D to turn the plunger, while at the same time permitting the plunger to reciprocate independently of the gear.

Inasmuch as the heel-seat plunger affords no vertical support to the gear D, an independent support must be provided. In the drawings ahub cl,havin g an annular groove CZ', is shown extending from one side of the gear. This hub slips into yan open bearing in the arm A4, the groove engaging a ixed portion of the frame and preventing vertical displacement. The introduction of the plunger into the gear and the plunger-bearing CL4 effectually holds the gear in position.

Reciprocating motion is imparted to the plunger through the cam B3. A yoke E, having a pair of arms e, provided with open slots e', straddles the plunger, the slots e engaging grooves cl in the plunger, whereby the plunger is free to rotate within the slots, but has no IOO reciprocating motion relatively to the yoke E. rlhis yoke is provided with a stud e2, which, as shown in Fig. l, is surrounded by an antifriction-roll. The stud e2, with its roll, is fitted in the cam-groove b3 of the disk B3.

From this description it will be apparent that as the shaft B revolves the plunger C will be caused to revolve by means of the intermeshing l gears and also to reciprocate by the action of the cam upon the roll carried by the yoke, the length of stroke depending upon the dimension of the cam-groove.

The lower end of the plunger is recessed, and mounted within the recess is a hammer C5, held in its outer position by a spring C6, but free to move inward against the tension of the spring. A pin C7 on the hammershank engages the end of a slot in the plunger when the hammer is in its outermost position and prevents complete withdrawal thereof. The operating-face of this hammer is preferably a plane surface in order to beat the heel-seat flat.

A horizontal counter-beating plunger F is arran gedrbelow the driving-shaft and parallel thereto, and therefore at right angles to the heel-seat-beating plunger. The manner of mounting and the movements of this counter-beating plunger are identical with those of the heel-seat-beating plunger and need not, therefore, be described in detail. Power is transmitted from the shaft B through a verw tical shaft G, mounted in a bearing A6 of the frame, the two shafts having intermeshing gears B4 and G'. The lower end of the shaft G is provided with a bevel-gear G2 and cam G3, similar in every respect to B2 and B3. A gear H for rotating the plunger F is mounted upon the standard A2, similarly to the gear D, and meshes with the gear G2. A yoke I engages the plunger and is provided with a stud and cam-roll for engaging the cam-groove g3, whereby the plunger is reciprocated. A yielding hammer F5 is mounted in the outer end of the plunger, this hammerbeing similar in con struction to the hammer c5, except that the beating-face thereof is preferably concave.

A jack K for holding the shoe which is being operated upon is carried by a slide L, provided with flanges Z, engaging grooves in the base A, whereby the position ofthe jack may be adjusted. Any suitable means-such, for instance, as a hand-wheel (not shown)-may be employed for locking the jack in position while a boot or shoe is being operated upon. Also, if desired, suitable means may be provided for adjusting the jack vertically.

seat and counter of the boot or shoe.

The operation of the machine is as follows: A lasted shoe is placed upon the jack K, with the heal-seat immediately below the hammer e5 and the counter directly in front of the hammer F5. The machine is now started in operation, and the two plungers C and F are rapidly reciprocated and at the same time rotated, delivering resilient blows upon the heel- These parts are rapidly and accurately beaten into the proper shape, the material adjacent the heel-seat being iiattened and the counter and its seam relieved of any irregularities. On account of the rotary movement given the hammer-plungers absolute uniformity of results are secured. Preferably the hammers are operated so as to give simultaneous blows, though this is not absolutely essential.

The spring vaction of the hammers obviates the danger of marring the leather on account of the blows being too heavy and also obviates the necessity for perfect adjustment of the jack, as a slight dierence in height or a slight horizontal displacement is of no moment, the hammers being able to follow 11p their work.

From the above description it will be seen that I have produced means whereby heelseats of lasted shoes may be beaten even and true and counters smoothly and symmetrically formed in a rapid and convenient manner.

I-Iaving described my invention, I claim as new and desire to protect by Letters Patent of the United Statesl. A heel-seat and counter beating machine, having in combination, a suitable jack for supporting a lasted shoe, a hammer for beating the heel-seat of such shoe, a hammer for beating the counter thereof, and connected mechanism for operating the hammers, substantially as described.

2. A heelseat and counter beating machine, having in combination, a suitable jack for supporting a lasted shoe, a yielding hammer reciprocating vertically above such jack, a second yielding hammer arranged and reciprocating at right angles to the first-named hammer and means for operating the hammers, one hammer beating the heel-seat, and the other the counter of said shoe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CLARENCE L. EATON.
