LUKE HALE, OF HOLLIS, NEW HAMPSHIRE.

CHEESE-PRESS.

Specification of Letters Patent No. 818, dated June 30, 1838'.

To all 'whom t may concern Be it known that I, LUKE HALE, of Hollis, in the county of Hillsboro and State of New Hampshire, have made certain Improvements in Presses for Pressing Cheese, and that the following is a full and exact description thereof. n

This press is of the kind which is denominated self regulating, in which the weight ofthe cheese is made to yield a power by which its own pressure is effected, and

which power is increased as the pressure goes on. Y

In the accompanying drawings A, A, is the bed piece of the machine, which in one constructed by me, is three feet and a half long, four inches wide, and one inchanda half thick.`

B, B, are two upright posts, these aremade of inch stuft', six inches wide at the bottom, and three inches at top.; they are four feet `high from shoulder to shoulder, and two feet apart at their inner edges. They are tenoned into the bed piece, and also into the cap piece C, which is three inches thick, and a foot wide. Thesemeasurements, however, and such others as may be given, are intended only as` examples of what I have found to answer very well in practice; but they may be departed from in any degree without altering the nature of the invention.

Within the uprights B, B, there is a sliding frame D, D, E, F, capable of rising and falling within the uprights, E. The cap piece of this frame, is four inches wide, and one and a half inch thick. The bed piece F, is four inches wide, and three deep. The side pieces D, D, are of the same size, with the cap piece E. V

A follower Gr, is made to play up and down to the distance of three inches, more or less, from the cap-piece E; its dimensions may be the same with that of the bed piece F. The distance between E, and F, is v eighteen inches.

H, H, are two straps of iron, passing into mortises in the follower G, and held there by stout joint pins, a, a; they eXtend down' and pass through mortises in the bed piece F, where they are attached to the kneed 1evers, to be next described.

I, I, are two levers, having iron knee plates b, Z2, firmly riveted to theirV upper ends, and friction rollers 0, c, at their lower ends, which rollers traverse back'and forth on the bed piece. There are two `holes in each knee piece, two inches apart; through those marked d, d, jointl pins pass by which they are attached to the bed piece, and

others at e, e, by which they are attached tov the straps H, H.

Upon the cap piece C, of themain frame,g`

there is a windlass, turned by a winch, and provided with a ratchet wheel and pawl.

The ropeorstrap f, isV attached at one end Y to the windlass, and at the other to the fol-` lower G, and by Vturn'ingthe winch both the l follower and the framein which itslides,

may be raised. l In `usingthis press the'follower the levers I, I, into a position nearly,y vertical. The cheeseLis then to be placed upon the bed piece, on a suitable platform, and

then raised, when Vthe weight of the cheese, and any additional weight',put, so as to bear upon'the bed piece F, will cause the levers I, I, to draw the follower down, and as it .descends these levers will be continually inclaim to have greatly improved the arrange and inner` frame are to be drawn up, whichxwill bring `7a the space between it and the follower Gy filled in with plank, or in any other con-V f venient way. The pawl'of'the windlass is.

ment of the respective partsby which this A end is attained; that is to say I claim- The manner in which I have combined and connected the levers I, I, below the bed of the press,`with the bed,`the iron straps, and the follower, substantially as above set forth.

LUKE HALE.
