I, JAMES STOTT of 126 Lever Street Bolton in the County of Lancaster, Engineer,
do hereby declare the nature of my said invention to be as follows:-
This invention is intended to provide means whereby lubricants, such as, oil and oil
and water employed in steam and other engines and machinery can be collected,
separated, and strained so that the same may be used and re-used until the lubricating
qualities are thoroughly extracted, thereby reducing the cost of same to a
minimum.
The waste oil or oil and water from the crank shaft, crank pin, piston rods, and other
parts of an engine are conveyed through pipes or otherwise to a cistern provided with
sieves of varying degrees, through which the oil or oil and water passes leaving refuse
or solid matter thereon. The water in the lower part of the cistern rises up a cavity
or chamber on the side of the cistern and out by a pipe or nozzle to a drain or
otherwise. The upper end of the cavity or chamber is provided with a vent to prevent
syphoning. In the cistern at any convenient height is fixed a pipe communicating
with a cistern,fixed at a lower level through which the oil flows, leaving the water in
the upper one to the level of the outlet. The connection between the cisterns,can be
stopped by inserting a plug in the mouth piece on the top end of the said pipe.
Each cistern is provided with glass water gauges to enable the quantity of oil and
oil and water to be ascertained, also with a tap for the purpose of emptying. Nothing
but oil or other analogous liquids used as lubricants are admitted to the lower cistern,
from which they can be drawn or pumped as required.

Improved Apparatus for Treating Waste Lubricating Oils.
I, JAMES STOTT of 126 Lever Street, Bolton in the County of Lancaster, Engineer,
do hereby declare the nature of my said 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 is intended to provide means whereby lubricants, such as, oil and oil
and water employed in steam and other engines and machinery can be collected,
separated, and strained so that the same may be used and re-used until the lubricating
qualities are thoroughly extracted, thereby reducing the cost of same to a minimum.
The waste oil or oil and water from the crank shaft, crank pin, piston rod, and other
parts of an engine is conveyed through pipes, or otherwise, to a cistern provided with
sieves of varying degrees, through which the oil or oil and water passes leaving refuse
or solid matter thereon. The water in the lower part of the cistern rises up a cavity
or chamber on the side of the cistern and out by a pipe or nozzle to a drain or otherwise.
The upper end of the cavity or chamber is provided with a vent to prevent syphoning.
In the cistern at any convenient height is fixed a pipe communicating with a cistern
fixed at a lower level through which the oil flows, leaving the water in the upper one
to the level of the outlet. The connection between the cisterns can be stopped by
inserting a plug in the mouth piece on the top end of the said pipe.
Each cistern is provided with glass water gauges to enable the quantity of oil and
oil and water to be ascertained, also with a tap for the purpose of emptying. Nothing
but oil or other analogous liquid used as lubricants is admitted to the lower cistern,
from which they can be drawn or pumped as required.
Fig. 1 is a sectional elevation of my improved apparatus for treating waste lubricating
oils or other lubricants-Fig. 2 is a front elevation of same-Fig. 3 is a sectional
elevation through line A' B' in Fig. 1, and Fig. 4 is a plan with top removed.
Oil, or the mixture of oil and water or other lubricants employed for lubricating
the crank shaft, crank pin, piston rod, and other parts of an engine, or the various parts
of machinery is conveyed to the pipe A attached to the cistern B by means of the tap
or valve C. The cistern B is fitted with the loose sieves D through which the
lubricant and water passes into the same. The meshes of the sieves D are of such a
gauge as to allow only the oil or oil and water or other lubricant to pass through, the
refuse or solid matter being arrested therein, from whence they can be gathered or removed
at will. The top of the cistern B is provided with the lid or hinged cover E to admit or
remove the sieves D as well as that of cleaning. If desired the lubricant, to be treated,
can be poured into the sieves D by means of a bucket or other vessel.
When the oil and water or other lubricant are admitted to the cistern B the water
falls to the bottom and passes up the chamber or cavity G on the side of the cistern B
leaving the oil or lubricant floating on the top in the cistern B. To prevent oil or
lubricant passing up the chamber or cavity G a sufficient quantity of water is poured
into the cistern B to cover the inlet at the bottom end of same before admitting the

page_text: lubricant for separation or treatment. As soon as the oil or lubricant rises to the top
of the pipe H it flows down the same into the sieves D¹ in the cistern F, leaving the
water behind in the cistern B. The cistern F is provided with the lid or hinged
cover E' for the purpose before described.
When a sufficient quantity of water has been collected so as to fill the cistern B to
the level of the outlet I it flows away through the valve J and pipe K; the latter may
be connected by a pipe to a drain or otherwise. The chamber or cavity G is provided
with the vent hole L to prevent syphoning. The cistern B is fitted with the tap M
to empty the same of either water or lubricant at will. The top end of the pipe H is
disposed slightly higher than the outlet I for water to ensure oil or lubricant only
being admitted to the cistern F. In case it is desired to wash the oil or lubricant or to
cleanse the cisterns clean water is conducted thereto by the pipe N and tap or valve O.
The connection between the cisterns B and F can be stopped by placing the plug P in
the top end of the pipe H. The cistern F is supported on the stand C, and the
cistern B on the cistern F, the pipe H being connected by the union M'; the whole
making a self-contained and compact apparatus which may be constructed and adapted
to stand in any suitable position according to the various requirements.
The cisterns B and F are provided with the glass water gauges Q and R to enable
the quantity of oil and oil and water or other lubricant to be ascertained in each. The top
end of the top gauge Q is fitted with the open ended vent pipe S; the bottom end of the
bottom gauge being provided with the plug T for cleaning the same.
The gauges R
are provided with the plugs T for cleaning.
The oil or lubricant admitted to the cistern F can be drawn therefrom through the
tap V, or by the rotary pump W through the pipe X, which forces it up the pipe Y to
the various parts of the engine or machinery requiring lubrication, and so on being
used over and over again until the lubricating qualities are thoroughly extracted.
The pump W is driven by the band Z from any convenient source.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
For separating oil and water or other lubricants and for treating waste oils and
lubricants, the construction and arrangement of apparatus consisting of the cisterns B
and F, with the sieves D and D', chamber or cavity G, supply and discharge pipes and
taps, connecting pipe H, and glass water gauges, substantially as herein described and
illustrated by the drawings.
