LANSING KELLOGG, OF RAVENNA, OHIO.

CHEESE-PRESS.

Specification of Letters Patent No. 6,101, dated February 6, 1849.

T 0 all fao/0m t may concern Be it known that I, LANSING KnLLoGe, of Ravenna, in the county of Portage and State ot Ohio, have invented certain new and useful Improvements in the Cheese-Press, of which the following is a full and exact description, reference being had to the annexed drawings of the same, making part of this speciication, in which- Figure 1 is a perspective view, Fig. 2 is a section taken through a part of the post B in the line m and Fig. 3 is an elevation of the part of the post in front of the section.

.The nature of my invention and improvement consists in placing between a pair of toggle j o-int levers, and a screw which operates therein, an elliptical or other spring in such a'manner that it is compressed by the torce applied by the screw to the levers, and by its ei'fort to expand again has the eect of continuing the pressure of the levers upon the cheese or whatever subst-ance is placed between them and the platen after the screw has ceased to operate. The screw may also be so arranged as merely to be used for the purpose of compressing the spring whichin this case would alone act upon the toggle joint to produce the necessary compression. The combined action of the toggle oint and spring produces a steady, continuous, and moderate pressure which'seems to be the peculiar action best adapted to the pressing of cheese, which by too sudden and violent pressure is forced through the cloth and hoop in' which it is contained, and it not long enough continued the whey is left in it which materially deteriorates its quality.

In the accompanying drawings A is the platform of the press, it is of any suitable size, and is most conveniently made of thick plank, upon this platform the two uprights B B are erected; between these uprights the platen a is placed, also the transverse pieces o in which mortises are made to form guides for the piston C, t-he binding beam D on which is the point of support for the levers, and likewise the guide piece Z in which a slot is made to guide the toggle joint levers E E and spring F in their` lateral movement.

The screw z' compresses the spring F by forcing it against the toggle joint e being attached to it by a swivel joint s. The nut in which the screw turns, and which is of course its point of support is in the post B, and turns on an axis n as shown in Figs. 2 and 3.

The spring may be made of any approved form but I prefer an elliptic of the kind in common use for carriages.

The several parts of this machine may be made of any material which in the view of the constructor is most suitable 0r convenient.

` The operation of this press being an alogous to that of all others upon the toggle' joint principle and quite obvious from an inspection of the drawing, I have not deemed a detailed description of the same here, to be necessary.

That I claim as my invention and desire to secure by Letters Patent, is-

The combination of the spring, with the screw and toggle joint as herein set forth, or in any other substantially similar manner by which the same effects are produced.

In testimony whereof I have hereunto set my hand and aiiiXed my seal, this seventh day of October A. D. 1848.

LANSING KELLOGG.
