UNITED STATES ELIAS BLANEY, OF MARBLEHEAD, MASSACHUSETTS.

Specification forming partof Letters Patent No. 118,185, dated August 22, 1871.

To all whom it may concern:

Be it known that I, ELIAS BLANEY, of Marblehead, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Shaping the Soles of Shoes, of which the following is a specication:

My invention has for its object the shaping of shoe-soles after they are pegged or sewed 5 and is designed to supersede the necessity of shaping by the hammer. Itbelongs to that class ofmachines in which a die or former is depressed by a screw upon the sole, which is placed upon an iron last arranged beneath the former, suficient pressure being given to form the sole into proper shape; and my invention consists in an arrangement ofdevices by which the last carrying the shoe is reciprocated alternately under the former to be pressed, and out toward the front of the machine for changing the shoes, and combining with this movement an automatic method of raising and depressing the screw, the two movements corresponding with each other, so that the machine may be operated by power rotating continuously in one direction.

The drawing represents, in Figure 1, a sectional elevation of my machine. Fig. 2 is a sectional elevation showing the shipping apparatus.

Similar letters of reference indicate like parts in all the gures.

The frame of the machine A is substantially made of cast-iron. B is the platen or bed, upon which the sliding socket C traverses between the guides D. The last E is fitted into the socket C. The sliding socket C is reciprocated by means of the screw-shaft I, having a right-and-left-hand screw-thread cut on the same portion of the shaft. At each end of the termination of the screwthreads on the shaftF two movable collars, e a, are placed to which is attached a sliding piece, o, having guide-slots in one end so arranged that the traversing fork o will be guided in a straight groove around the shaft when the sliding socket is required to be stationary, and guiding the fork into the right-and-left-hand threads to move the socket out or in. The collars a c fit in a groove in the sliding guide b. Bymovingthis sliding guide the collars, with their pieces c, are moved to their proper position to form the straight groove aronn d the shaft or turn the fork into the threads of the screw. The sliding guide b is moved by the operator to start the machine, and automatically by a spring, g, after the shoe is pressed. The traversing fork o is tted into a movable piece, n, which is held by a set-screw, allowing the sliding socket to be moved out or in, so that different-sized shoes may fit under the former. 0n the shaftF is placed the drum G and driving-pulleys H II. Motion is communicated by belts from the drum G to the clutch-pulleys I I on the shaft K. One of the clutch-pulleys is driven by an open belt and the other by a cross-belt. A clutch, L, is iitted on the shaft K, and as it is connected with either ofthe pulleys I I the shaft K is revolved in opposite directions. A bevelgear, M, is placed o'n the shaft K and drives a bevel-gear, N, which is placed on the screw O, which it turns by means of a sliding key in a spline in the screw O, the gear being held in place by a clasp iitted into a groove in the hub. At the lower end of the screw O the follower P is fastened, which is moved up or down by the screw O, and guided by the w. ys Q. A former, It, is placed on the followerP and is depressed upon the shoe with sufficient power to shape the sole by means of the screw 0. The surface ofthe former maybe nickel-plated to prevent the oxidation of the iron and soiling the leather. The clutch L is made to connect either pulley I I by means of a sliding fork, S, which is operated by the attendant by a lever, to engage with the pulley driven by the cross-belt. This gives a rotary motion to the shaft and bevel-gears, which turn the screw to depress the follower and former. The arm T is fastened to the follower, and as it is depressed a slide, U, is forced outward by means of a pin working in the inclined slot W and striking against a weighted lever, Z, moving it just beyond its center of gravity, so that it falls over, :and its lower end, striking on a pin in the slide a, throws the clutch into the pulley driven by the straight belt just as the requisite pressure is given to the sole, thereby reversing the screw and raising the follower. The arm T extends from the follower through the platen, by which it is guided, and carries a movable catch, which, as it rises, trips the latch-catch Y, which holds the sliding guide in place, throwing thc fork o into the screw-thread and moving the shoe out to the iront of the machine.

As the screw O raises the arm T the inclined slotWmoves back the slide U, a pin on this slide the clutch midway between the pulleys I I, stoppin g the rotation of the shaft K while another shoe is being' placed on the last. The han d-lever is then moved by the operator, which throws the clutch Linto the pulley driven by the cross-belt at the same time it moves the slide U to throw the fork o into the screw on the screw-shaft F.

The screw on the screw-shaft F may be dispensed with, and the sliding socket moved by hand.

I claim as my inventionl. In a machine for shaping the soles of shoes, the devices shown and set forth, by which the last is reeiprocated alternately under the former and out toward the front of the machine, substanti al ly in the 1n aimer and for the purpose described. v

2. lThe combination of the screw-shaft F with the clutchL and pulleys I I, operating in the manner substantially as and for the purpose specied.

3. In a machine for shaping1 the soles of shoes, the sliding piece c, for the purpose of guiding the traversing fork o, substantially as set forth.

4. The sliding socket C, made adjustable by means of the movable piece n, for the purpose set forth.
