IMPROVEMENT IN B-EATING-OUT MACHINES FOR BOOT AND SHOE SOLES.

Specification forming part of Letters Patent No. 149,723, dated April 14, 1674; application filed March 6, 1874.

, blc those skilled in the art to practice it.

In the ordinary beating-up machine, which is used to bring the outer sole of a boot or shoe to its ultimate shape upon the last, and to lay and compress the channel-flaps, there is a complicated compound mechanism employed to connect the pedal-lever with the driving-shaft, so that by the power the main toggle-levers shall be straightened to bring the platen-former down upon the sole 1 r of the boot supported by the stationary bed,

the workman having often to repeatedly exert his weight upon the pedal, and a great outlay of strength, before he can bring the parts into connection for the shaft to operate.

In my invention I obviate entirely this defective construction, by combining with the main lever, and jointed to its end, a hinged gearplate orperforated plate, into which engages a gear-pinion or star-wheel on the driving-shaft, and a friction-wheel operated by a a hand-lever, to move a clutch-wheel and bring the shaft-pulley into connection therewith, the main lever being connected with the lower cross-head of the platen by a system of toggle-joints; When the boot or shoe is in position, the clutch-lever is moved by the operator to throw a belt-pulley into connection with a pulley fast on the shaft, and the shaft will then be turned, its pinion in turning forcin g up the gear-plate with which it engages, thereby operating the toggle-levers to draw down the platen the operator havingto use no force to bring the parts into connection. My invention consists in the combination, thus generally described.

The drawing represents a construction embodying my invention.

Figure 1 shows the machine in sectional elevation. Fig. 2 is a front elevation of the. same.

a denotes theframe of the machine b, the

bed upon which the shoe-holdin g last andlastplate are supported, and over which is the movable platen-head c, carrying the mold d, by which the last is to be compressed. The head 0 is fixed to two vertical rods, 0, extending through the bed, and down through the frame, said rods being connected at their bottom ends by the cross-head f. Springs 9 raise the platen to its normal position; and, connecting the cross'head f with the frame or stationary bed, is a series of toggle-links, hi kl m, the link t being jointed at one end to the stationarybed, and the link on at one end to a cross-beam, a, the links h z is being jointed together at o, the links 70 l m at p, and the link I being also jointed at its opposite end to a lever, q. At the front end of this lever is jointed the gear-plate or bar 0", having teeth or perforations engagingwith the teeth of a pinion, s, on the shaft t, the rotation of the shaft in one direction straightening the toggle-links to bring the platen down, and its movement in the opposite direction raising the platen. This shaft carries a fast pulley and a loose belt-pulley, which are made as clutch-pulleys, and, to bring them into engagement, a friction-pulley, u, slides on the shaft, this friction-pulley being connected to a hand or clutch lever, 02, extending through the frame and up to position to be accessible to the operator, who, by moving it, readily brings the belt-pulley into connection with the shaft-pulley or disengages them. When the pulleys have been clutched and the platen thereby drawn down, the platen may be held by a hook, a2, hooking upon a cross-rod, y.

By this method of construction and operation, all the real work is effected by the machine without drawing upon the strength of the operator.

I claim-- I In combination with the platen, toggle-links and lever 00, the gear-plate r, pinion s, shaft 25, clutchpulley u, and clutch-lever v, all combined and operating substantially as shown and described.
