PROVISIONAL SPECIFICATION.
Pumps Driven by Vaporized Oil Motors.
I THOMAS BALLARD MARCHANT of Verney Wharf, Verney Road,
Rotherhithe New Road in the County of Surrey, Engineer do hereby declare the
nature of this invention to be as follows:-
This invention is the application and adaptation of the power generated by the
vapourization and subsequent explosion in a cylinder or cylinders of mineral oil or
oils, the said power being then applied to the purpose of actuating the mechanism
of pumps for raising or otherwise moving liquids of various kinds.
And I do not limit the scope of my invention to any specific design for applying
the said motive power of vaporized oil to the mechanism of the pump to be
actuated thereby but I shall have to modify such mechanism in accordance with
the nature of the pumping power required and as circumstances may in each case
demand.
For instance, in some cases the piston operated upon by the explosive force of
the vapourized oil may be coupled to the same piston rod (or a continuation of the
same) as the pump plunger, or piston, or bucket as the case may be, is fastened to,
or there can be interposed between them gearing to alter the ratios of velocity of
the said piston & pump plunger.
Further-there may be any number of each of the said pistons, or plungers, and
their relative sizes will also require modification.
Again by this invention when for instance it is designed as a portable pumping
apparatus there will only need the conveying of the liquid fuel to the point where
it is being employed as the water used to cool the motor cylinder I arrange if
necessary to be taken from the pump itself, thus simplifying the apparatus,
although this part of the invention would-(like the design of other parts) be as
above mentioned subject to modifications such as the nature of the liquid being
pumped.

I THOMAS BALLARD MARCHANT of Verney Wharf, Verney Road
Rotherhithe New Road in the County of Surrey, Mechanical 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 :-
The above named invention hereinafter to be described can be adequately
described for the purpose of my final specification without drawings and I have
since the filing of my Provisional Specification ascertained that the specification
can be best carried out in the following manner although I do not-as stated in my
first specification bind or limit the scope of this invention to a special way of
constructing the same but must as ocasion demands modify the details of general

page_text: arrangement in accordance with the nature of the pumping required to be
performed and the liquid to be pumped.
As a general rule I find it best to place the cylinder of the oil motor A as near
as possible to the working barrel of the pump B it is to actuate, and if necessary
I cast the said motor cylinder A and the said working pump barrel B in one casting
or what is its equivalent fit to the same outer casing separate liners to form the
working bore D of the motor engine and that of the pump.
I also find it expedient to sometimes pass the whole of the liquid being pumped
through the circulating space C around the said working bore of the oil motor in
which case no extra valves or pipes whatever are required but in other instances
where only a part of such liquid is required to be used I prefer to fit a small
outlet from the delivery pipe G Sheet 3 of the main pump to the one end of the
circulating water space which is fitted with an outlet pipe E, which is led to the
delivery pipe of the main pump at a point further from the delivery valve I than
is the said inlet. Between the outlet and inlet pipes is fitted a cock or sluice J by
adjusting which any given quantity of the liquid being pumped can be utilized as
desired, as by shutting entirely the cock or sluice valve J the whole of the liquid
being pumped must pass through the cooling space C. On the other hand when
the said cock or sluice valve is opened none of the liquid being pumped is passed
through C.
Further by placing the motor cylinder and the pump barrel at the same end of
the machine the necessary gear K & L to correct the relative speeds of the motor
piston M which is rapid, and that of the pump ram or bucket N which is slow is
found room for at the other end of the machine thus keeping all necessary pipes,
valves & pumping gear at one place on the machine.
I do not claim to have invented new mechanical motions or new combinations of
gear, or new gear for the actual vapourization of the said oil to obtain motive
power but the utilization of this power for a new purpose, namely the actuation of
pumping mechanism together with the utilization of the liquid pumped when this
liquid is of a suitable nature to give the required cooling effect.
Having now fully described the nature of this my invention and the manner in
which the said invention is to be performed I declare that what I claim is
1st. The application of the power generated in vapourized oil motors to the
work of pumping liquids.
2nd. The utilization of the liquid operated upon to circulate around the working
cylinder of the oil motor for the purpose of cooling the same.
3rd. The combination in one machine mechanically connected together of the
vapourized oil motor, the pumping mechanism together with the circulating pipes
for cooling the motor cylinder as described and for the purpose set forth.
Dated this 11th day of March 1896.
THOMAS BALLARD MARCHANT.
