We, GEORGE HENRY RICHMOND and JOSEPH CROWTHER, both of 5, Derby
Street, Moss Side, Manchester, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention to be as follows; —
In carrying out our invention we construct a cylindrical casing and divide the
same at about the centre of its length into two compartments by means of a
plate and through this plate we depend a smaller cylinder one end of which pro-
jects above the plate and the other to within a short distance of the bottom of
the casing and fill the same with filtering material covered with a seive. A small
air pipe is passed from the underside of the division plate to the top of the upper
compartment and a draw off cock is provided at the bottom of the lower com-
partment and a cock at the bottom of the upper compartment for the purpose of
drawing off any water which may accumulate the operation of this apparatus is
as follows:-
-
The oil to be filtered is poured into the upper compartment and from this
compartment it passes through the filtering material contained in the smaller
cvlinder into the lower compartment where it arrives in a perfectly clean state
and may be drawn off at will.

Improvements in Oil Filters.
We, GEORGE HENRY RICHMOND and JOSEPH CROWTHER, both of 5, Derby
Street, Moss Side, Manchester, in the County of Lancaster, Engineers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The object of this invention is the construction of a filter for oil so that the
same may be used over and over again. In order that our invention may be
readily understood and carried into effect we have hereunto annexed a sheet of
drawing to which we will refer in describing the same.
The drawing is a sectional elevation of our invention and A represents a casing
preferably cylindrical covered by the lid B we divide the casing A at or near the
centre of its length by means of the division plate C through which plate we
depend the cylinder D and rise the perforated cylinder E and we surround such
perforated cylinder E on both sides with filtering material F and G and round
רנסD

page_text: the outer ring G of the filtering material we depend the perforated cylinder H
from the cover I and from this cover I we rise the tube J and terminate such
tube J with the hand wheel K. The cylinder D is intended to contain the filtering
material L supported by the perforated plate M which plate M is carried by the
air tube N passing up through the tube J and terminating in a regulating nut O
for the purpose of putting pressure upon the filtering material L. The plug P
is for the purpose of drawing off the mud and impurities and the cock Q for the
purpose of drawing off the filtered oil. The filtering material consists of woollen
felt.
It will now be seen that upon filling the chamber R with oil to be filtered the
heavy impurities will settle on to the plate C and the oil will pass through the
perforated cylinder H and the filtering material 1 and G and on to and through
the material L into the chamber S where it arrives in a perfectly clean state and
may be drawn off at will by means of the cock Q.
The air escapes from or is admitted to the chamber S by means of the tube N.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The combination and arrangement substantially as and for the purposes herein
before described and illustrated on the accompanying drawing.
Dated this 20th day of October 1898.
