IMPROVEMENT IN OIL-PRESSES.

Specification forming part of Leiters Patent No 136,716, dated March 1l, 1873.

To all whom it may concern: I

Be it known that I, WILLIAM M. FORCE, of the city of Newark, county of Essex, in the State of New Jersey, have invented new and useful Improvements in Oil-Presses and I do hereby declare that the following specification, taken in connection with the drawing furnished, is a full, clear, and exact description thereof, which will enable others skilled in. the art to make and use the same.

The nature of my invention consists in an improved method of supporting the platesin a hydraulic press in such a manner as to dispense with the bolts or links by which the system of plates are secured in their respective positions, and making independent supports, by which the same object is secured, with the additional advantage of a cheaper and more reliable arrangement of all the parts, for the purpose of expressing oils from seeds, nuts, or kernels.

Referring to the drawing, Figure 1 represents a side elevation of a press with my irnproved attachment; Fig. 2, a perspective view of the same; Fig. 3, a sectional view of the old plan of suspending the plates with the nuts removed from bolts W.

A, bed or base of press; B, uprights; C, supports or racks; D, ears or other suitable projections; E, plates or platforms; H, cap, forming a part of the frame of press; K, ram or plunger, operated in the usual manner, &c.

To enable others skilled iuthe art to make my invention I will describelin detail, although on referring to the drawing the nature and object are clearly exhibited.

The bed or base, with its uprighfs, cap, and piston, is `similar to those in common use,

and is made of iron, or other tough suitable f material, and in the usual manner. The racks C or other supports, upon which the plates E are held in position by their projections D,

are made of iron or other suitable material. Said supports may be secured by bolts or screws in the usual-way to the standards B. The plates are similar to those in general use, with the exception of the ears or projections D, which are made to rest in the positions prepared for that purpose on the rack or upright.

The usual mat, containing the meal, seed, grain, or nuts, is placed between the plates for the purpose of expressing the oils, which is performed by the moving or raising the ram, by which means the plates are forced nearer together, compressing the cake snticiently to remove the oil, which escapes at the outer edges, and from thence conducted to a proper receptacle prepared for the same.

On referring to the drawing it will be seen that the arrangement of the rack is such as to enable the plates to raise up perpendicularly with the action of the ram, and to recede back again Ywhen the power is Withdrawn. The ease by which the plates may be removed independently of each other, by slightly raising one side of thel plate (diagonally) sufficiently for the ears to clear the uprights, when the same is withdrawn for repairs and cleaning, is important.

yHaving thus described my invention, consist-ing of devices in combination with a hydraulic press, and the manner of operating the same, I claim as new and desire to secure Letters Patent of the United States- An apparatus consisting of rack C, or its describedequivalent, plates E, provided with ears or projections D, constructed in the manner, and in combination with any suitable motor or press, as and for the purpose substantially as described.
