IMPROVEMENT IN WINE AND CIDERPPRESSES.

ThevScheule referred to in these' LetrersrPatent and making part of the same.

' Toallwhomit may concern Be it known that I, THOMAS W. Gnrslnn, of Riusy selville, county of Logan and State of Kentucky, have invented a new and useful Improvement in Zine and Ciderflress; Aand I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to the annexed drawing making .a partof this specification.

--The nature of my invention relates to that class of wine and cider-presses in which the grapes or apples are placed in a perforated vessel and the juice pressed therefrom by means of a screw or other mechanical power,

My improvement has for its object the saving of time and an increased-yield 0i' wine or cider, and consists in placing a spring ofany suitablenature and capacity under the foto'f the screw;

In construct-ion my invention is substantially as follows:

A A are two upright posts supporting the cast-iron beam B and thewooden cross-timber C.

' The drawing represents a vertical cross-section taken througlrthe center of Athe screw.

I) is the curb.

E, the.pomace.-

At F is seen thebed of -the press, and

G, an elevated bed, on which the curb D rests.

H is the screw, and Y I, the ordinary cast-iron fo'ot, held in place by the set-screw i. n

My improvement consists in placing on the disk 'J the cap K, with a projection, k, on the bottounand placedlin the center therein.

.A rubber spring, L, its over the projection 1.', but does not entirely iill the cap K.

In operation my improvement isI as follows:

vWhen the curb is first filled with pomace and moved under the press the cap is not used, as but little pressure is required to bring the pomace down turned back so as to give room for the introduction ofthe cap K, with the rubber spring L, under thel foot I.

The screw is then again brought down as far as the operator has strength, with a lever which compresses the rubber almost to its greatest capacity'. v

. 'Ihe operator may then proceed to grind apples, and the spring1 L will continue the pressure, giving ,the pomaee time to settle until the force of the spring has been expended. l

It is found in practicethat to overcome the-capillary attraction existing between the fluid and pomace is such as to require a certain amount of time to separate them, or, in other words, the operation mustbe slow.

Now, in order to accumulate the force exerted by Athe operator on the screw, and to have this force continued after the screw has been left, I place a spring of any suitable construction or material, such as rubber, steel, brass, dto., between the `end of the screw and the poinace, or may be attached between the nut on a screw-press and the cross-beam, or under the bed of the press, as may seein best to serve the pur'- pose here intended; or a scroll-spring, such as used in clocks, may be woumlaround the screw or other parts communicating witlrit, so as' to cause a continuous downward pressure of the screw by the reaction oi' the spring. v

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is v The combina-tion, in a wine and cider-press, of the springs L with serew H andA screw-plate I', substantially as shown, for the purpose set forth.
