UNITED STATES STANLEY J. BEEBE, OF UNION, NEW YORK.

UPPER-LEATHER-CUTTING MACHINE.

Specification of Letters Patent.

Patented Aug. 16, 1921.

Application filed November 29, 1919. Serial No. 341,457.

T 0 all whom it may concern Be it known that I, STANLEY J. Bnnen, a citizen of the United States, residing at Union, in the county of Broome and State of New York, have invented certain new and useful Improvements in Upper-Leather- Cutting Machines, of which the following is a specification.

My invention relates to an improvement in upper leather cutting machines in which upper leathers are cut by dies, the dies pressed down upon the leathers by a hammer actuated by electricity. And it has for its object to provide a compact, readily and accurately operated machine for upper leather cutting, which eliminates the gearing, drive shafts, pulleys and fly wheelaccessories, with the dangers incident therefrom which pertain to belt driven cutters. IVith these objects in view my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter fully described and pointed out in the claims, reference being had to the accompanying drawings in which Figure 1, is a side elevation of my device.

Fig. 2 is a front end elevation of my device.

The same reference characters denote like parts in each of the several figures of the drawings.

In carrying out my invention, I provide a table A mounted on legs 2, 2, etc.. which in turn stand upon a base 3; the table A is constructed preferably of metal. and has at its rear end thereof. and as an integral part thereof, the standard A, terminating in the forward projecting horizontal arm B; slidably mounted in and operating through said arm B and table A, I have the shaft 5; suspended from table A and beneath the same, in any convenient manner I have the hangers 9, 9, and mounted on which in any suitable manner I have suspended the leaf spring 10; in the center of which spring on its upper surface, I have mounted the shaft 5, which supports box 6 having therein the flexible couplings 7, from which box 6 projects the pivot 8 on which shaft 5 is pivoted at its lower end. Above the table A, I have mounted on shaft 5, in any convenient manner the hammer F; pivotally mounted on ivots 23, 23 projecting from standards A, I have the handle rod 24 and in loop formation 24 about shaft 5 and connected at its outer end with handle 25, which is slidably mounted in the vertical opening in the hammer F; the rear end of rod 2 1 terminates in a contact point. Firmly secured to the under side of leaf spring 10, I have mounted shaft 11. on which I have mounted the flexible couplings 12 mounted on beam 13 and on the lower side of coupling 12, I have the connecting shaft 11 supported on connecting bar 18. The rear end of beam 13 is supported by the pivoted hanger 15 and the front end is mounted on the jointed tubular standard 15. in which is mounted a spring controlled or toggle joint a; mounted on base 3, I have the electrical solenoids 17, 17, supporting bar 18. Mounted on the back of standardB, I have the electrical contactor C, and with battery wires 20 and 21 connected therewith, and extending to main sources of electrical supply; mounted also on standard B. I have the switch D, having the electrical wires 22 and 23-wire connecting one side of switch D and to main line 20 with the solenoids 17. 17 and line 22 connecting to one side of switch D, through controlling coil of switch. C and then to main line 21, and contactor C, in turn closing the main line to solenoids 17, 17; the pivoted lever rod 24: contacts with switch D. In a convenient position beneath hammer F and on table A, I mount the cutting block E. It is to be noted that the beam 13 with its end pivotal support, and the joint support at the opposite end, furnishes a steadying control over. the blow of the hammer as it is struck. while the spring support, causes the hammer to resume its normal position. after the electrical actuation has ceased. In the operation of my device, the die is placed at any desired position upon the leather placed upon the block; and the hammer moved laterally to any convenient position over the die; then by downward pressure upon the handle, the rod 24 is pressed downward, causing the electrical contact at switch D, and the electrical circuit being thus formed, causing bar 18 and shaft 5 to be drawn downward. and the blow of the hammer is struck and the cutting made; the electrical contact being released. the pressure of spring 10 forces shaft 5 and with it hammer F upward to its normal position.

Thus having described my invention, what I claim as new and for which I desire Letters Patent, is as follows:

1. In an upper leather cutting machine, a

table, a standard from the rear portion of the table surface and having a forwardly projected arm alined'with said surface, a shaft vertically mounted in said arm and table and slidable therethrough, a leaf spring carried by the table, pivotal connection between said shaft and spring for support of said shaft, solenoids disposed beneath said pivotal connection and connected thereto for downward actuation of said support and shaft against the tension of said spring, a cutting block on said table, a hammer carried by said shaft and latera llyad justable thereon over said block, a circuit including said solenoids, and a manually operable circuit closer on said standard for energizing said solenoids whereby the ham- Iner is actuated. V

2. In an upper leather cutting machine, a table, a standard thereon, a shaft slidably disposed through said table and standard, a hammer carried by said shaft above the table, a spring support for said shaft carried by the table, a solenoid for drawing said shaft downward against the tension of said spring support, a circuit including said solenoid, a guide handle for said hammer pivoted on said standard, and a circuitcloser on said handle. I p

In testimony whereof I have atfixed my signature.

STANLEY BEEBE.
