PRESS.

Application filed September 11, 1920.

To all whom it may concern:

Be it known that I, ARCHIBALD JACKSON STRANE, a citizen of the United States of America, residing at Tamaqua, in the county of Schuylkill and State of Pennsylvania,

have invented certain new and useful Improvements in Presses, of which the following is a specification.

This invention relates to presses and more particularly to presses designed to simultaneously pressa multiplicity of objects. The primary object of the invention 1s to provide a press of this character whereby each of the press points of the press may be caused to exert an individually controllable degree of pressure upon the object which it engages to the end that a uniform degree of pressure may be exerted upon the objects being pressed irrespective of variations inthe degree of thickness of the objects pressed or in the degree of preparation for pressing of; said objects or to the further end that different degrees of pressure may be exerted upon the objects being pressed, if this be desired.

It is a further object of the invention to provide a press of the character above set forth wherein the movable press head may be given a quick movement to approximate pressing position and thereafter given a relatively slower but correspondingly more powerful movement to complete the press ing operation.

Further objects and advantages of the invention will be set forth in the detailed description which follows.

In the accompanying drawing Figure 1 is a view partly in side elevation and partly in section of a press constructed in accordance with the invention, and

Fig. 2 is a fragmentary plan view thereof.

Like numerals designate corresponding parts in both of the figures of the drawing.

Referring to the drawing 5 designates a movable press head the shank 6 of which travels in a guide 7 carried by the bed 8. A guide block 9 and guide plate 10 mounted upon supports 11 and 12 have press points 13 mounted to move vertically therein. The guide block 9 is stepped as indicated at 14 and the press points are provided with heads 15 which rest upon the upper faces of these steps. By referring to Fig. 2 it will be seen that these press points are arranged in rows Specification of Letters Patent.

along the several steps. A work plate 17 carried by the head 5 receives the objects A that are to be pressed, these objects being alined with the lower ends of the press points.

Levers 18 are fulcrumed at 19 and their ree ends rest upon the heads 15 of the press points. Vfeights 20, only one of which is shown, are connected by cables 21 with the ends 22 of the levers 18. These cables are passed over pulleys 23 in such manner that the weights act to move the free ends of the levers downwardly and thereby cause said levers to exert a pressure upon the press polnts proportional to the size or weight of the weight 20. Thus it will be apparent that when, during upward movement of the press head 5, a predetermined degree of pressure has been given the objects A no further pressure will be exerted upon these objects even though said head continues its upward movement because after that degree of pressure has been reached the press points will yield upwardly. Thus a uniform degree of pressure may be exerted upon each and every one of the objects A if all of the weights are the same or any individual press point'or row of press points may be caused to exert a pressure difi'erent from the others by properly varying the weights. It is manifest that springs may be substituted for the weights and the same result be secured.

Any desired means for actuating the head 5 may be employed. This head may be actuated by hand or it may be actuated by power or a combination of the two may be used. For purposes of illustration I have shown a hand operated toggle combined with a hydraulic plunger the arrangement being designed to give a quick lift to the head 5 under the influence of the toggle, to the point where the objects A are just engaged with the press points, the actual pressing operation being accomplished by power through the medium of the hydraulic plunger. The construction referred to comprises the toggle links 24 and 25, link 26, bell crank lever comprising the arms 27 and 28, the latter forming a handle and a hydraulic plunger 29 operable in a hydraulic cylinder which is conventionally indicated at 30.

It is to be understood that the invention is not limited to the construction shown because changes fairly come within either the terms or. the spirit of the appended claims.

Having described my invention, what I- claim is:

1. In a multiple press a plurality of press 7 points, a work-carrying head movable toward said press points to simultaneously bring the work into engagement with all of said press points and individually adjustable Weighted pressure creating means for each of said press points.

2. In a multiple press a plurality of press points, a work-carrying head movable toward said press points to simultaneously bring the work into engagement with all of said press points, a pivoted lever for each of said press points and means engaged with said levers and acting through said levers to exert pressure upon the several press points.

3. In a multiple press a work-carrying head mounted for movement, a plurality of press points, a member in which said press points move said member having a stepped upper surface and said press points being supported upon the several steps of said surface, a plurality of levers disposed atvarying levels and pivoted uniformlyintermediate their ends the inner ends of said levers resting upon the press points and yieldable pressure creating means connected to said levers outwardly of their fulcrums;

L. A structure as recited in claim 3 where- 'in said press points are disposed in rows along each of said steps.

5. A press comprising a movable worlcarrying head in combination with manually operable means for, moving said head to approximate pressing position and power means for completing the pressing movement of the head.

6. A press comprising a movable worksaid press points" and exerting pressure thereon. V g In testimony 1n the presence of two: witnesses.
