An Apparatus for Straining or Filtering Oil used for the purposes
of Lubrication.
We, TOM WALTON and CHARLES CROSSLEY WALTON, both of Kildane Place,
Rochdale, in the County of Lancaster, Tin Plate Workers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an apparatus for straining or filtering lubricating oil
more particularly after the same has been used for the purpose of lubricating the
journals of shafts or other parts of machinery. The said apparatus is adapted and
designed to be situate within a cistern used for the storage of oil which cistern may
be an ordinary store oil cistern as now used principally in large manufactories.
According to our arrangement when the oil has passed through the process of
filtration the same is then allowed to pass into the store cistern any foreign or
insoluble matter which may be contained in the oil being removed the oil may then
be re-used in a practically purified state as regards particles or matter in
suspension. In accordance with our construction this invention consists of a
hollow vessel which we term the "oil vessel" of suitable form preferably circular
and covered at its upper part with a lid or cover the said vessel is provided on the
outside with a casing of larger diameter than the vessel and concentric therewith
thus a space or cavity is formed around the vessel and made steam tight but con-
veniently provided with an inlet and an outlet orifice provided for the admission
and exit of steam or other hot medium if desirable we may dispense with the
steam cavity such cavity being employed when the lubricant to be filtered is of a
thick or viscid nature necessitating liquifaction in order to admit of the same being
treated as the case may be. At the lower part of the vessel we employ two or
more cells or receptacles having a communication with the interior of the oil vessel
by means of openings each opening being covered with a suitable filtering medium
an opening is also provided in the bottom cell of the series and covered with a
suitable filtering medium the filtering material employed may be of porous textile
material or metal gauze the media employed may be of different degrees of porosity
or mesh according to the material used.
The above described apparatus when required for use is placed within a store oil
cistern being supported in position therein by means of a flange extending outwards
from and around the upper part of the "oil vessel" the flange seating upon the
upper edge of the store cistern.
The oil to be treated is poured or allowed to pass into the oil vessel in any
convenient manner which oil by gravitation passes therefrom through the filtering
media of the series of cells below the "oil vessel" from thence into the store oil
cistern.

An Apparatus for Straining or Filtering Of used for the purposes
of Lubrication.
We, TOM WALTON and CHARLES CROSSLEY WALTON, both of Kildane Place,
Rochdale, in the County of Lancaster, Tin Plate Workers, 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 :-
This invention relates to an apparatus for strairing or filtering lubricating oil
more particularly after the same has been used for the purposes of lubrication such
as the journals in mills, workshops.
In order to better explain the nature of our invention we have hereunto annexed
a sheet of drawings in which like letters of reference indicate like parts, in which
Fig. 1 represents a section of our filtering apparatus,
Fig. 2. being a plan of Fig. 1.
Fig. 3. representing our invention complete with oil receiving cistern in section,
Fig. 4 being a plan of Fig. 3. and
Fig. 5 shewing a sieve.
According to our construction we provide a hollow vessel a provided with a
series of sieves which are suitably supported therein, which sieves or strainers
may be of any convenient "mesh the first and second sieves near the upper part
of the vessel we preferably provide with elevated parts 62 in order to increase the
filtering area of the sieves, we place on the sieves if desired pieces of fibrous
material. The vessel a which we term the oil vessel is situate within a receiving
vessel as shewn in Fig. 3. When in working position the oil is allowed to fall
into the vessel h, which we provide with an intermediate bottom having an outlet
or orifice k, communicating with a chamber, cocks and m being provided, the
former to withdraw water which may pass with the oil into the receiving cistern h,
and the latter to draw oil from the cistern h.
If desired inlet and outlet orifices may be provided to communicate with a
cavity or jacket surrounding the oil vessel for the purposes of heating the oil as it
is passed into the vessel a.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of a removable oil vessel a provided with a series of sieves b
with a receiving vessel provided with outlets for the withdrawal of oil and water
separated from each other substantially as herein described.
