PRES-PLATE FOR GOTTOLT-SEEDl AND OTHER OIL PRIEISSES.

Specification of Letters Patent.

Application led September 9, 1919. Serial No. 322,658.

To all whom t may concern.'

Be it known that I, NELSON B. HENRY, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Press-Plates for Cotton-Seed and other Oil Presses, of which the following is a specification.

My invention has relation to an improvement in plates for cotton-seed and similar oil presses, and in such connection it relates more particularly to the construction and arrangement of such plates.

In cotton-seed presses, of well known types, the oil cake is pressed between plates in superposed relationship. The plates were provided with ears, or lips, so that they could slide up and down upon the columns of the press.

The object of my present invention is to provide the plates with means whereby the same will interlock during the pressing operation, whereby pressure may be exerted more evenly upon the cake, and the plates may ride freely and evenly on each other during the application of pressure to the cakes in the press. An added object of my invention is in so arranging a portion of the interlocking means that the same may constitute a wall to retain the expressed oil in a chamber surrounding the operative portion of the press plate and conduct it t0 a suitable discharge opening.

The nature and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which:

Figure l, is a top or plan view 0f a press plate embodying my invention.

Fig. 2, is an end elevational view of one of the plates; and,

Fig. 3, is a vertical sectional view taken on lines 3 3 of Fig. 1, and illustrating two of the plates in operative relationship.

Referring to the drawings, l represents the main body of the plate, having its upper face traversed longitudinally by the oil conducting ducts 2. Upon this body l is secured the platel 3, having shallow transverse grooves 4 with perforations 5 extendin the press,

ing through the plate 3 at the points where grooves 4: cross grooves, or ducts 2.

Patented July 27, 1920.

The body l is formed integral with the end'flanges 6 and side rims 7. The end flanges tionship with the body l, but some distance therefrom, whereas the rims 7 are curved and terminate at a point adjacent t0 the plate 3, leaving a space between the sides of said plate and a rim 7 to receive and guide a vertically arranged lug S projecting from and preferably integral with the rim 7 andl body 1. Extending laterally from each corner 9, which is formed to partly engage one of the columns 10 0f the press and to slide up and down thereon.

In practice, a series of plates are arranged the four brackets, or ears, 9 of each plate sliding on columns 10 in the guidingV of the plate in the press. An oil seed cake 1l with its cloth covering l2 or, as it is called, the cake of cooked meats, is placed between two adjacent plates in a press,.the lower lugs 8 of the upper plate entering the space bet-Ween plate 3 and rim 7 of the lower plate, as Fig. 3 as the plates are brought together in the pressing operation. It is manifest that as the pressure is brought to bear upon the plates in the press, the cake 1l will be held asin an open ended box and will be pressed evenly and completely. The interlocking ofthe two plates insures the riding of the plates more freely on the columns l0 of the press and adds greatly to the strength and durability of the plates.

Having thus described the nature and objects of my invention, what I claim is:

l. Ina press plate, a body, a iiange formed at each end of the plate, curved side flanges for the plate, said side flanges bent inwardly toward the body to constitute one member of an interlocking device between consecutive press platesand vertical lugs projecting from the bottom of the side flanges ,to const-itute the other member of said interlocking device.

2. In a press, a series of superposed plates, each provided on the sides with curved flanges and lower lugs, said flanges and lugs clearly indicated in of the plates is a bracket or ear constituting a means for interlocking the platesduring the pressing operation.

3. A press plate having a central body, side flange-s and end rims Vsurrounding said 5 body and integral therewith, corner brackets projecting laterally fromV the side flanges, lower lugs projecting vertically from said flanges, and a cake supporting plate secured to the body and extending toward, but not meeting the side anges. 10 In testimony whereof I have signed my naine to this specification.
