Description

Nrrnn Sfrnfrns CHARLES E. SNYPP, OF GRETNA, LOUISIANA.
.PRESS-PLATE.
SPECIFICATION forming part of Letters Patent No. 632,157', dated August 29, 1899.
Application filed March 4, 1899.I Serial No. 707,793. (No model.)
To all whom, it may concern:
Be it known that I, CHARLES E. SNYPP, a citizen of theUnited States,residingat Gretna, in the parish of Jefferson and State of Louisiana, have invented certain new and useful Improvements in Press-Plates and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in press-plates for oil-presses, although it may be used in other relations where filtering is accomplished under pressure; and it consists in the constructions and combinations of parts, as hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure lis a horizontal section of my improved pressplate. Fig. 2 is a side view of the same, parts being broken away and a part being shown in section; and Fig. 3 is a similar view of a modification.
My improved press-plate consists of a backing A, provided with grooves or slots d, located in the central portion of the backing and with holes a running from the outer surfaces of the backing to the central grooves or slots d. In contact'with the backing A is another plate C, provided with holes c, each shaped in the form of a truncated cone with the apex next the backing A. The perforations c, however, are not arranged over the perforations a', and this is an important point in the construction of my press-plate. The plate C may be fastened to the backing A, if desired, but this is not necessary. The material from which the oil is to be expressed is driven by pressure in any suitable form of press against the plate C, whereupon the oil will pass through the perforations c,thence between the plate C and the backing A, through holes a', and thence out through the grooves or slots ct, the sharp feather-edges of the perforations c prevent= ing any solid matter from passing through with the oil.
All the parts of my improved plate are preferably formed of metal; but I no not restrict myself to this material.
In Fig. 3 is shown a modification in which the holes a are replaced by grooves a2. In other respects the modifications are identical.
Changes Amight be made in various details of my invention without departing from the spirit thereof, and I wish it to be expressly understood that I do not limit myself to exact details shown and described.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. A press-plate composed of a backing provided with grooves and a plate in contact with said backing and provided with conical openings arranged with their larger ends outward, the plate and backing being arranged so that the openings therein do not register with each other, substantially as described.
2. Apress-plate composed of abacking provided with central grooves or slots and openings running from the surfaces of said backing into the slots thereof, and a plate in contact with said backing provided with conical openings arranged with their larger ends outward, the plate and backing being so arranged that the perforations therein do not register with each other, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES E. SNYPP.
