PROVISIONAL SPECIFICATION.
Improved Filter for Oils, Lubricants, and other Fluids.
I, WALTER HENRY WILLCOX, Engineer, of 36 Southwark Street Southwark,
in the County of Surrey, do hereby declare the nature of this invention to be as
follows:-
For
The object of this invention is to clarify oils, lubricants, and other fluid.
this purpose I provide two cylinders, one smaller than the other, into the smaller I
fix four grids, between which I place sheets of gauze, canvas, crushed charcoal, or
any well known filtering material, it is then screwed into the centre of the larger
cylinder, or containing vessel, and the oil, lubricant, or fluid is filtered by forcing
its way from the larger cylinder, or containing vessel up through the filtering
materials at the bottom of the smaller cylinder, or containing vessel.

COMPLETE SPECIFICATION.
Improved Filter for Oils, Lubricants, and other Fluids.
1, WALTER HENRY WILLCOX Engineer, of 36 Southwark Street in the
County of Surrey, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this invention is to clarify oils, lubricants, and other fluids. For
this purpose I provide two cylinders, or containing vessels, one smaller than the
other. Into the smaller I fix four grids between which I place gauze, canvas,
crushed charcoal, or any well known filtering materials. It is then screwed into the
centre of the larger cylinder, or containing vessel, and the oil lubricant, or fluid is
filtered by forcing its way from the larger cylinder, or containing vessel, up
through the filtering materials at the bottom of the smaller cylinder, or containing
vessel.
Having now explained the nature of my invention, I wili proceed to particularly
describe in what manner the same is to be carried into effect by the aid of the
following drawing, and description. The drawing represents a vertical section of
the filter.
A, is the outer cylinder, or containing vessel.
B, is the smaller cylinder, or containing vessel, which is screwed inside the larger
one, into, or, on to the delivery pipe C.
D, is the upper grid in which is screwed down upon D₂, between these grids
place a sheet, or sheets of gauze, or canvas, or both. D, and D, are the lower
grids, D, is screwed down upon D, between which is a sheet of gauze.

The space between D, and D, is filled with the crushed charcoal, or any well
known filtering material.
E, is a centre delivery pipe to which the grids are screwed.
F, is a cock upon the delivery pipe for the clarified fluid.
The cock G, is for running off any excess of water, and is also for when the
filtering materials and cylinders are being cleaned out.
The oil, lubricant, or other fluid is poured into the outer cylinder, and by its
gravitation is forced up through the filtering materials into the inner cylinder from
whence it can be drawn off through the delivery pipe.

page_text: Having now particularly described, and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is―
Firstly. The employment of one cylinder, or containing vessel screwed, or
fastened into another in order to obtain the required pressure upon the fluid for
rapid filtration.
Secondly. The application of grids for binding the filtering materials together,
upon a centre, or delivery pipe, in, or under an inner cylinder, or containing vessel.
Dated this day September 23rd 1891.
