IMPRCVE'IOVIENT IN CHEESE-PRESSES.

To all whom 1J/may concern Beit known that we, GEORGE B. Boomen, THOMAS G. MORSE, and Rurns E. Bosonnnr, of Phoenix, in rthe county of Oswego and State of New York, have invented a new and useful Improvement in Cheese-- Presses; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others to make and use the same, reference being had to the accompanying drawing forming a part of this specication.

The drawing shows a perspective View of our improvement, in which- A a is the frame-work.

G e are the links or knee-joint levers, that are actuated by a right-and-left hand-screw, D, to throw the press beam. l

The frame-work A is made double, so that slots are formed between the main nprights, andthe press beam B is made with tenons b b, at its ends, that occupy and trav l vertically in said slots.

The knee-lin *O o are also made deuble, and the nuts e e, that connect the links with the screw, are placed between them.

The beam B has two upright projections G G, idly to it, and these pieces pass up through sn. es in the cross-flame A', and act as guides to stendy the thrust of the press-beam B and its follow-` Lipper ends of the links C c are stationary, or have` fixed fulcrum on the frame-piece A', and the entire throw of the links is given to the beam B, and this causes the screw D to have a vertical movement equal to half that of the press-beam.

T o accommodate this differential movement of the screw J), vertically, the guide-standards G -G are vmade with vertical slots g.

The press can be run down'atrst with a crank placed on the screw at d, but it cannot be used toward the latter end elthe operation, as from the vertical movement of the screw, and the inward movement of the nut, the end of the screwis necessarily unsupported, and the screw is liable to be broken by the crank; .and the press is driven down by a hand-wheel, F, fixed to it at the center.

This wheel is fixed on the screw, between the guidestandards G G, and ittedsnuglyin between them, to prevent end wise play of the screw,- that would tend to depress one-end of the beam B` -aud make the guides bind.

-By this construction, all the parts are heid firmly in the proper position,

powerfully.

The follower H is fastened rigidly to the press" beam, and the thrust of the press is regulated byre.-

moving the follower from the press-beam andsubstituting a thicker or thinner piece vof blocking for the block h.

The ends of the links C c can be pivoted to the sides of the beams B and A', instead of resting in the metallic shoes, and the press, by this means, be shorteued up'ncarly a foot, 'ifdesired By these means we obtain a press thatworks free and evenly, and that is powerful, and made at alightv cost.. v .l We do not claim the use of knee-levers operated by means of a right-and-left hand-screw, as herein described, as this is not new; but

Having thus described our invention',

That we claim, and desire toAsecure by Letters Patent, is-v A cheese-press, composedof the double frame A a A', the press-beam B h .ilzgsliding standards G G, double levers C 0,-nuts e, and the screw D, withra, hand-wheel, F, and square lend d, all constructed, ar ranged, and operating substantially as described.

The above specification of our invention signed by.

us this 8th day of September, 1870. A
