To all whom it may concern: Y

Beit known that I, FRED KILLEFER, a citizen of the United States, residing at Los Angeles, California, have invented certain new and useful Improvements in Forging- Presses, of which the following is a speciication.

My invention relates to improvements in forging presses and t-he object of the invention is to provide a press of this character which while capable of exerting great pressure upon the blank or article to be treated, will yet be capable of quick and ready adjustment to accommodate itself to a large variety of work. It is desirable in devices of this character to use toggle joints as the means for applying the necessary pressure as by this means a very powerful pressure may be exerted by very simple mechanism, but in the use of toggle joints as the means for applying the necessary power to the forging head, only a limited movement of the head can be secured consistent with the maximum amount of power to be derived from the toggle joint, and consequently under ordinary conditions the press could only handle work of very limited range of thickness. There are mechanical object-ions against adjusting the anvil.

It is the object of the present invention, therefore, to provide means by which the forging head may be quickly and easily adjusted without disturbing the operating toggles, the adjustment being made at will to accommodate the press to work of greater varying thickness.

The invention includes the novel features of construction and arrangement and combination of parts hereinafter described, and particularly set forth in the appended claims.

It is illustrated in the accompanying drawings, in which Figure l is a side elevation. Fig. 2 a front view, and Fig. 3 is a transverse sectional view on line 3 3 Fig. 2.

Referring by reference characters to this drawing', the numeral l designates the anvil and 2 the forging head, the latter being guided by guides 3 carried by standards 4, which tie the anvil to an upper cross member 5.

6 represents the toggle links which are connected at the top to the cross member 5 Aand at the bottom to the bearing member 7 and it will be understood that the toggle members are operated by the usual operating mechanism 6a, not necessary to be particularly described herein.

For connecting the bearing member 7 and forging head, I provide a screw 8 having one end rotatably connected with one of these members and its other end threaded into the other member. I preferably rotatably connect the head of the screw with the bearing member at the bottom of the toggle joint by any suitable rotatable connection and screw its lower end into a correspondingly threaded opening in the forging head, it being understood of course that the screw is made of a size and strength commensurate with the force which is to be applied. The screw carries a pulley 9 which may be secured thereto or formed rigidly therewith. Around this pulley passes an endless belt or band l0 which extends horizontally to the side of the apparatus where it passes over idle pulleys 1l and thence vertically downward to a pulley l2 journaled upon a suitable shaft and provided with a hand wheel or crank or other means for rotating the same. It will be seen that by the rotation of the hand wheel in the proper direction, the screw will be turned and the head quickly raised or lowered, while at the same time not interfering in any way with the toggle action or forging movement o-f the head Vas the movement of the head under the action of the toggles is so slight as not to interfere with the belt connections described.

Coil springs 13 are provided on each side of the toggle arms 6 to assist in returning the forging head 2 to its raised position. They are secured at their lower ends to the forging head by suitable eye-bolts 14 and at their upper ends to the cross piece 5 by the eye-bolts 15.

Having thus described my invention, what I claim is l. In a forging press, a stationary anvil, a vertically moving forging head, operating means for the forging head, a screw con necting said forging head and operating means, and flexible connections extending to the side of the press for operating the screw.
