MACHINE FOR STAMPING BOOTS AND SHOES.

.JPECIIEICATION forming part of Letters Patent No. 296,513, dated April 8, 1884.

Application filed January 31, 1884. (No model.)

To all whom it may concern:

Be 1t known that we, CHARLES llI.'BOLLES and MIcHnLL E. BYRON, citizens of the United States of America, residing at East Pepperell, in the county of Middlesex and State of Massachnsetts, have invented certain new and useful Improvements in Machines for Stamping Boots and Shoes; and w e 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part of this specification.

Our invention relates to machines for stamping the soles of boots and shoes; and it con sists in the improvements and combinations of parts hereinafter described, whereby the boots orshoes may be readily mounted in position to receive the stamp, the stamping devices readily brought into operation, and means provided whereby the elevation of the boots or shoes to the stamp are guided so as to receive the stampat the proper point.

The invention further consists in certain other novel features and parts to beset forth and explained hereinafter.

Inthe accompanying drawings,formingpart of this specification, Figure 1 is a perspective view of a stamping-machine embodying our improvements. Fig.2isarearelevation,showing the parts of the machine below the central table. Fig. 3 is a plan view of Fig. 2. Fig. 4; is a perspective view of the devices arranged in the upper part of the machine, looking from the rear right-hand side; and Fig. 5is a detail view of the arrangement of the adjustable block in the upper part of the machine for effecting the projection of the stamps.

In the present application the arrangement and operation of parts are somewhat similar to the construction described and illustrated in our application for Letters Patent filed July 27, 1883, Serial No. 102,081. The arrangement of supporting-frame, central table, and

top is like thatdesoribed and illustrated in said application. Adrive-shaft, A, is mounted in bearing-boxes a, bolted each at the rear of the side sections of the frame, the projecting ends of said drive-shaft carrying, respectivelya band-pulley, B, and a balance-wheel, G, and pinion b, as shown in Figs. 2and 3. Bearing, boXes c,bolted to the center of the side sections of the frame, support a shaft, D, one end of which projects beyond the side of the frame, and has keyed thereon a gear-wheel, c,which meshes with the pinion b. Upon said shaft D, near one side of the frame, rides a toothed disk, (I, provided-with a hub, cl, grooved to receive a spline or feather, (Z on the shaft D, so as to revolve therewith, but otherwise loose,to slide longitudinally thereon. A collar, (2 adj ustably bolted to the shaft D between the side of the frame and the disk (Z, affords a means of regulating the sliding movement of said disk toward the side of the machine. A second toothed disk, d, is loosely mounted on the center of the shaft D, so as to turn thereon, and is provided with a sleeve, upon which is formed an eccentric disk, E.

Upon the shaft D, between the side of the frame at which the gear-wheel c is located and the eccentric dish E, is rigidly mounted a cam, F. A rod, G, playing longitudinally in perforations in the sides of the machine, and through a perforation in a vertical standard, G, bolted to the base of the frame, has

bolted to it at one sidean arm, 6, bifurcated at its front end to embrace the hub of the disk (2 by resting in an annular groove, (i formed in the hub d of the same. A yoke, f, bolted to the rod G at one side, has secured to it one end of a contracting spring, f, which embraces a portion of the rod G, and bears at its other end against the standard G, tends to normally maintain said rod in the position shown in Fig. 2. A lever, H, pivotally secured on the pint-1e g of a bracket, 9', has a roller, 9, at its front end, to bear against the cam F and be oscillated thereby, while its rear end plays in the yokef on the rod G. A bar, I, pivotally secured at one end to the side of the frame, is reduced at its other end to pass through a vertical slot, formed in the standard G. A leaf-spring, g", secured on the upper side of the end of the bar and bearing against the portion of the standard forming the top of the slot, maintains the end of the bar down in the slot. A bar, J, is bent up at its front end to form a fulcrum on which to pivot the center ofa bar, K, the rear end of which rests between the bar I and the rod G, and is provided at its front end with a treadle, K, the depression of which will raise the bar up in the slot in the standard G. The eccentric F is grooved peripherally, so as to permit curved sections F F to be bolted thereon, so as to em brace the same. The upper section, F, is provided with a neck, F which terminates at its upper extremity in a horizontal disk, Fflwhich has bolted thereto a second disk, F a rubber gasket or cushion, F, being interposed between said disks F" and F The upper disk, F has centrally a vertical extension, F the upper end of which bears in a recess therefor formed in the lower end of a vertical cylinder, M, which plays in an opening formed in thetable. and in a collar, N, bolted to said table, a spline or feather, m, on said cylinder engaging a groove formed in the table and in the collar N, so as to prevent the rotation of said cylinder in the table and collar. A bar, 0, is secured to the upper end of the cylinder M, and extends parallel with the side sections of the frame. A jack, 0, provided with a suitable threaded shank, is adapted to engage and be supported in an opening formed in the bar 0. A heel-rest, P, is pivotally selower ends each a number.

cured to the front end of the bar 0, as seen in Fig. 4, and is provided at its upper end with a curved block, 9. A rod, P, connects the heelrest P with the lower end of a lever, P, centrally pivoted at the rear end of thebar O, the upper end of the lever being provided with a vertical slot, 12 into which plays a pin, q, of a block, Q, the base q of which is dovetailed to slide in and be engaged by a dovetailed recess, g formed in the upper end of a standard, Q, mounted on the rear end of the bar 0. A bent plate, Q", bolted at its front end to one side of the block Q, extends back rearwardly and terminates in a rack, pends from the under side of the. top of the frame, so as to be capable of revolving in its suspended bearing, and has rigidly bolted thereto an arm, g, which carries at its outer extremity a curved bar, R, which is provided with a series of vertical perforations, in which arelocated stamp-dies a", which carry at their I These stamp-dies r are spring-seated in the perforations, so that the lower end of said dies are normally flush with the under side of the bar B. A curved rack-plate, B, is bolted to the under side of the arm q, immediately above a wedge-shaped lug, r, secured on the upper side of the block Q, and in advance of this wedge-shape lug r is secured a curved plate, '2, designed to act as a toe-rest.

Rigidly bolted on the lower end of the depending shaft Q is a disk, Q, a portion of the periphery of which is provided with gear-teeth H, which engage with the teeth of the rack g as shown in Fig. 4. The upper end of the shaft Q turns in a dovetailed box, Q which slides longitudinally in a dovetailed slot formed in A shaft, Q de-' the under side of the top of the frame, and said box is adapted to be rigidly secured at any point along said slot by means of a set-screw, q. A block, S, is secured on the lower end of a threaded rod, 8, which turns in a threaded opening therefor formed in the forward part of the top of the frame. The upper end of the threaded shaft 8 is provided with a crank-handle, s, for revolving said shaft.

The operation of the machine is as follows: The band-pulley B is driven in the direction of the arrow, Fig. 1. Motion is thereby imparted in the same direction to the drive shaft A and pinion b thereon, which in turn rotate the gear-wheel c and its shaft D, thereby rotating the toothed pinion (Z, which is out of engagement with disk d*, which does not rotate. The revolution of the shaft D also rotates the cam F,which vibrates the lever'H on its pivot, and thereby intermittently forcing the rod G toward the side of the framein which the drive-pulley is located, and against the spring-traction. When said rod G is moved as above described, the spring is prevented from effecting the return of said rod to its first position by reason of the end of the bar I being forced down in the slot 9 of the standard G by the spring so as to bear against the side of the arm 6, which holds the disk (1 in the disengaged position referred to. Vv'hen the bar is thrown up by the depression of the front end of the bar K, the spring on the rod G causes the movement of said rod toward the other side of the frame, carrying with it the arm 6, which in turn slides the disk cl in engagement with the disk (1, thereby turning said disk, its sleeve, the eccentric F, and effecting the elevation of the neck F and consequently cylinder M and devices connected thereto above the central table. \Vhen the stamping above the table (which operation will be freely set forth hereinafter) has been accomplished, the movements of the various parts are so arranged that the cam on the shaft.

D will again cause the lever H to move the rod toward the side of the machine on which the drive-pulley is located, thereby moving the arm 6, which in turn moves the disk (I out of contact with the disk (1". moving out of contact with the disk d" the eccentric has further rotated sufficiently to permit the descent of the cylinder M and parts connected thereto by gravity to its first position, when the operation is again repeated. The curved block on the upper end of the block is moved outward from the front of the machine, so 'as, by the arrangement of heelrest and eonnectingrod, to move the block rearwardly in the dovetailed slot, and consequentlythe rackplate Q", and thereby effects a quarter rotation of the shaft Q its arm (1, and the curved block R, located at the extremity of the same, the movement resulting in the block R, carrying a portion of the stamp ing devices, being thrown out of position. The jack 0 is then turned in its bearing toward one side, so as to permit the shoe to be' IIO As the disk (I is passed over the same when it is turned in the position illustrated in dotted lines, Fig. 1, with its toe in the direction of the block Q. The heel-rest P is then moved so that it will cause its curved block p to bear against the heel of the shoe, which movement of the heelrest P, by reason of the intermediate connections described, thereby moves the block Q forward, so that the toe of the shoe rests upon the forward end of the said block against the plate Q1. The forward movement of the block Q revolves the shaft Q and shaft Qfl thereby swinging the stamp-barR around in position above the shoe, each stamp-die, as it comes in contact with the upper-block S, being depressed, so as to project while in contact with said block from the under side of the bar R. The movement of the bar R ceases when the proper stamp-diehas been depressed, this being easily efi'ectcd by adjusting the devices so that certain stamps come successively into position as the distance of the block Q from the heel of the shoe increases, thereby regulating the stamps according to the size of shoe andlength of sole. Another adjustment can be effected by moving the dovetailed bearing of the shaft Q along its dovetailed slot. By providing only aportion of the disk Q with gear-teeth, said disk and shaft Q can only be revolved sufficiently to bring the bar B into correct position. The actuating devices beneath the central table now cause the cylinder M and the shoe-supporting devices to be elevated and bear against the stamp-bar R, and the shoe thus receives its proper stamps, the rigid stamp secured in the front of the top of the frame being impressed on the heel of the shoe, while the stamp of the bar R is impressed on the sole, and the shoe-supporting parts drop back by gravity. By revolving the rods the degree at which the stampdies project from the under side of the bar It maybe readily regulated. The cushion F receives the concussion of the stamping impact, and prevents communication of the shock to the parts below the table.
