IMPROVEMENT IN OIL-PRESSES.

Speciiication forming part of Letters Patent No. 47,44 l, datedApril 25, 1865.

To all whom it may concern:

Be it known that I, WM. V. MGKENZIE, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Oillress; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the a-rt to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure vl represents a longitudinal vertical section et this invention, the line .fr a', Fig. 3, indicating the plane of section. Fig. 2 is a transverse vertical sect-ion of the same taken y in the plane indicated by the line yy, Fig. 3.

Fig. 3 is a plan or top view ofthe same, partly in section.

Similar letters of reference indicate corresponding parts.

lhis invention consists in the use of doors sliding in grooves in the adjoining movable sides of the press boxes, said grooves being arranged in such a manner that they retain the slides rmly in position and compel them to close tight when the press is filled, and at the same time they do not interfere with the sliding motion of sides of the press boxes.

'lhe invention consists also in the application ot' a steam-supply, and ot' an exhaustpipe extending over the entire length of the press, and communicating' with each pressbox by small pipes in such a manner that said small pipes will have sntlicient spring to allow the sides of the press-boxes being moved the requisite distance, and all complicated `ioints in these pipes can be avoided.

A represents a press composed of a frame, B, with rigid end pieces-a, which are connected by longitudinal bars b. 'l`he bars form the guides for the sides B of the pressboXes C, and said sides are so arranged that they can be moved apart and Jforced together by a hydraulic press or any other suitable means.

The top and bottom of each press-box is formed by a slide, D, which is provided with a lip, o, as shown in Fig. l, and which is guided in grooves d, cut in the sides B, the proper places. By the means of the lips c the slides D are compelled to follow the motion of the sides B, and when these sides closeup, thesides drop into mortises g, as

shown in Fig. 3, where the sides are shown apart and the slides ready to enter said mortises. It will be noticed that the slides D are. never allowed to rise from the inner edges ot their guide-grooves, and, it' the box is iilled with lard or other material, nothing is allowed to ret between the slide and said y inner edges of the grooves which would prevent the same from closing tight, and at the same time the slide is constantly in place, it is not allowed to drop out, itis made in a simple and easy manner, and it is more durable than any other cover which has come under my notice.

The press-boxes are supplied with steam n from a pipe, E, which extends throughout the entire length ot' the press, and the eX- haust-steam is carried oit' through a pipe, F. These pipes communicate with the several press-boxes by means otl branch pipese f, and they are situated at such a height above the press, and said branch pipes are made so thin that the same retain spring enough `to allow of moving the sides B without rendery in g it necessary to construct them with a complicated joint.

The press can thus be supplied with steam in a simple and cheap manner, the pipes or joint are not liable to get out ot order, and the operation of pressing is materially A constructed and operating substantially as and for the purpose described.

3. Though l do not claim broadly thensc of steam for heating a press, I claim the pipes E F with branch pipes e f, arranged in combination `with the movable sides of a press, substantially as specified, so that said branch pipes retain suiiicient spring to allow of the motion of the sides of the pressboxes.
