An Improved Method for Supplying Lubricating Oil in Regular
Quantities, for Gas and Oil Engines and the like, and for
Supplying in Regular Quantities, Combustible Liquids for
Driving purposes.
JOHN FLETCHER SHAW, 3 Elvey Street, Newton Heath, Manchester, Engineer.
ROBERT HARRIS SHAW, 2, Elvey Street, Newton Heath, Manchester, Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method, for supplying lubricating oil in
regular quantities, for gas and oil engines, and the like, and for supplying in regular
quantities, combustible liquids for driving purposes.
This invention consists in a cup or receptacle with two seperate chambers, one
chamber preferably larger than the other. At a suitable position in the side of the
smaller chamber is an outlet for overflow purposes, and to the side of the said
smaller chamber or connected with it, is attached a piece of metal or wiper. In the
said cup in either chamber is a suitable tube or oil passage to convey the oil or
combustible liquid to the engine as required. It is immaterial in which chamber
the said tube is fixed, at the top of the said tube is fixed a piece of metal or wiper.
In a suitable bearings and at the top of the said cup, is a shaft and pulley, which can
be driven by any suitable means.
Connected with the shaft is a crank, on the said crank, are two dippers, one dipper
works in the larger chamber, and the other in the smaller chamber. The said
receptacle or cup has a suitable cover.
The operations are as follows-
The two chambers in the said cup are supplied with oil, the smaller one is filled to
the overflow outlet, the oil in the larger chamber is somewhat lower, than the overflow,
in the smaller chamber. As the shaft and crank revolve, the dipper in the larger
chamber is let down into the oil, and brought up by the crank, as the dipper is being
raised it comes against the piece of metal or wiper connected with the smaller
chamber and thus the oil runs down the wiper into the smaller chamber, and always
keeps the sinaller chamber full to the overflow. The dipper which works in the
smaller chamber is lowered and raised by the said crank, as the dipper is being raised
it comes against the wiper which is attached to the top of the said tube or passage which
conveys the oil to the engine. The dipper which works in the larger chamber raises
more oil into the smaller chamber, than the dipper which works in the smaller
chamber supplies to the tube or oil passage to the engine, the surplus oil in the
smaller chamber flows back into the larger chamber by means of the overflow. By
our improvement, while the level of the oil in the larger chamber is ever varying,
the oil in the smaller chamber is maintained at one level. So the quantity of oil
taken up by the dipper in the smaller chamber is regular, and thus gives a regular
supply of oil to the engine.
Without departing from the principle of our invention, the mode of lifting the oil
can be modified, if desired, instead of useing the crank, a small pulley or endless

page_text: band revolving with the shaft, and one part immersed in the oil, and as the pulley or
band moves round, they would take oil up and rub against the wipers. We do not bind
ourselves to any particular shape of dipper.

An Improved Method for Supplying Lubricating Oil in Regular
Quantities, for Gas and Oil Engines and the like, and for
Supplying in Regular Quantities Combustible Liquids for
Driving purposes.
JOHN FLETCHER SHAW, 2, Elvey Street, Newton Heath, Manchester, Engineer,
ROBERT HARRIS SHAW, 2, Elvey Street, Newton Heath, Manchester, Engineer, 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:—
Our invention relates to an improved method for supplying oil in regular quantities
for
gas and oil engines and the like, and for supplying in regular quantities combustible
liquids for driving purposes.
The accompanying drawings illustrate the said invention.
Fig. 1 is a sectional side view with cover.
Figs. 2 and 3 are sectional side views without cover.
Fig. 4 is a plan.

Fig. 5 is a sectional end view on line x, y.
Our invention consists in a vessel or cup " with two separate chambers "6"
and "c" the chamber "b" preferably larger than chamber "c." In the side of
chamber "c" and at a suitable position is an outlet "d" for overflow purposes.
Attached to chamber "c" is a wiper "e." In the said cup is a passage or tube "f"
to convey the oil or combustible liquid to the engine. In Figs. 1 and 2, above the
passage or tube "f" is fixed a wiper “g,”
," "i" and "j" are dippers, "i" is thicker
than "j." "k" and "" are cranks, "h" is a shaft, "m," m, are bearings in which
works shaft "h," which shaft is driven by a pulley n or any suitable means.
t
* " is a cover for said cup or vessel.
"
"
The mode of lifting the oil or combustible liquid can be modified if desired, as in
Figs. 3 and 5, instead of using the dipper "," an endless band "q" could be
used, running in contact with wiper "e" and instead of dipper "j" a piece of ganze
wire "p" could be brought before the mouth of tube "f" and the combustible
liquid be drawn down the tube "f."
Also, in Fig. 1, if desired, separate cranks "k" and ""could be used to work each
dipper "i" and "j."
t
"
The operations are as follows:-In Figs. 1 and 2 the two chambers "b" and "C are
C " is filled to overflow hole "d"-as the crank "k" and
supplied with oil, chamber ",
shaft "h" revolve the dipper "i" is let down into the oil in chamber "b," as the
"" is being raised it comes against the wiper e "and the oil runs down
dipper
wiper e
"into chamber "c" and always keeps chamber "c" full to the overflow, as
dipper "i" is larger than dipper "j" and lifts more oil than dipper "j."

As crank "k" revolves dipper "j" is lowered into chamber "c" and as it is being
raised it comes against wiper "g" above passage "f" and as chamber "c" is
1

page_text: always kept full to the overflow a regular quantity of oil is supplied to the
engine, thus, while the quantity of oil in chamber "b" is ever varying the oil
in chamber "c" is maintained at one level.
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 :-
1. Is a vessel with two separate chambers to contain lubricating oil or combustible
liquid, with overflow in the side of one chamber to keep oil or combustible liquid at a
constant level; a shaft, and crank, and dippers, and wipers, and tube, for the purposes
herein before described, and illustrated in the accompanying drawings.
2. Is a vessel with two separate chambers to contain lubricating oil or combustible
liquid, a shaft, and crank, and band, and gauze wire, substantially as and for the
purposes herein before described, with reference to Figs. 3 and 5, in the accompanying
drawings.
