IMPROVED CHEESE-PRESS.

TO ALL WIjIOM IT MAY OONCERN: Y

Be it known that I, JACOB ERDLE, of South Bristol, in the county of Ontario, and State of New 4York,l1ave invented a certain new and useful Improvement in Cheese-Tresses;` and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- The figure represents a central vertical s ection ofthe machine.

Myimprovement'consists lof the combination of the weighted lever and the screw, whereby an even and uniform pressure is produced, and which are capable of adjustment without removing the pressure, the whole being arranged andoper-ating substantially as hereinafter set-forth. 4

t In the accompanying drawing, A indicates the bed-plate, resting stationary on legspp; B, the curb, and C the follower, which is pressed down by the combined action of screw D, that turns in a nut in cross-bar E, and the weighted'lever, as will presently he described.

'Io the opposite ends of cross-baril are connected perpendicular rods a a, that `extend. down Vthrough hollow standards, b b, and connect at their lower ends to cross-'bar F. Extending ldown on opposite sides of the bedplate A are fixed bearings, c c,rin which rest the ends of the shaftGr, the shaft being provided with a crankbearing, el, that is jointed to lever e of cross-har F. On one end of shaft Gris secured a lever, H, having a weight, I, attached. c

By turningdown the screw D, the cross-bar E, not being stationary, will rise up on the threads of the screw, and consequently draw-up the connecting parts, and elevate the lever II. Then, by means ofthe weighted lever, a steady and uniform pressure is produced, therebydraw-ing` down upon the adjustable-parts until the ends of cross-bar E rest on top of the hollow standards b b, and prevent further pressure, when the screw D is again turned down, and the operation repeated as before. This isall accomplished without at any time removing the pressure from the follower. p

By simply inserting blocks (shown in'red lines) between the cross-bar F and bed-plate A, the parts may be held stationary, and the press operated by the Vscrew alone. i l y I amaware that presses have before been patented, in which a weighted lever has been used to produce a continuous pressure, without relieving the pressure iu readjustng, but such devices are much more complicated and expensive than mine, and much more liable to get out of order;A In my device the arrangement is very simple and cheap, and the operation performed with as little diculty as in ordinary presses, where screws alone are used. By simply turning down on the screw, the adjustable parts'are plaeedin position tov produce a continuous pressure, and still allow it to settle without overcoming thestrain. v

In contradistincton to such-arrangements-as above indicated, I combine the two siniplest and most eicc'tive mechanical powers, viz, the-screw and weight, lto readjust and continuodsly .apply the pressure, this being accomplished simply hy the square connection E-F, a a. l i

What I claim as my invention, and desire to secure by Letters Patent, isV

The arrangement and combination of' the screw D, cross-bars E F, rods a a, crankfshaft/ Gr, and weighted lever II, operating substantially as and for the purpose set forth.

In witness whereof, I have hereunto signed my name, in the'presence of two subscribing witnesses.

J'ACOB ERDLE.
