Complete Specification Left, 23rd Apr., 1896-Accepted, 23rd May, 1896
ALFRED GEORGE BROWNING, Gas Engineer 19 Duke Street Moss Side
Manchester do hereby declare the nature of this invention to be as follows:-
The first part relates to an air chamber & delivery pipe, which surrounds the
inside cylinder.
The second part relates to an inside cylinder.
The third part relates to an outside cylinder or working cylinder, with handle
or lever fixed on the blank top.
At the bottom of the inside cylinder a valve is placed, and just above this valve,
the delivery pipe is connected to the inside cylinder which is also fitted with a
valve leading to the air chamber.
By the act of working the outside cylinder upward the water or liquid is drawn
into the inside one & on the downward motion the compressed water or liquid is
forced through the valve in connection with the air chamber & delivery pipe.

ALFRED GEORGE BROWNING.
An Improved Fire Pump.
I ALFRED GEORGE BROWNING formerly of 19 Duke Street Moss Side,
Manchester, now of 5 Oakland Villas, Flixton in the County of Lancaster, Gas
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 :-
This invention relates to the construction of an improved portable force pump
designed principally for extinguishing fires, but the same pump may also be used
for watering gardens, washing windows and other analogous purposes.
My invention will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation thereof.
Fig. 1 on the drawing is a vertical section of my improved fire pump and Fig. 2
a plan view of the same.
Fig. 3 is a vertical section of a portion of the same drawn to a larger scale, and
Fig. 4 a horizontal section through about the line A-B on Fig. 3.
a is a cistern or vessel to contain water in which the pump is fixed, and which
may be made of any convenient form and dimensions. 6 is the air-chamber which
surrounds the inner fixed cylinder c, and the delivery pipe d.
e is the outside or working cylinder which works up and down outside the fixed
cylinder c and has attached to its upper closed end or top a cross handle for a
lever.
The cylinder e may be made to fit closely onto the cylinder c, or it may be
packed if required.
At the bottom of the fixed cylinder c is placed a valve g opening upwards so as
i Price 8d. \

page_text: to admit the water from the cistern or vessel a into the interior of the inner fixed
cylinder c and also through a valve h (also opening upwards) into the interior of
the air chamber b, and above this valve is placed the lower end of the delivery
pipe d to the upper end of which is fitted a flexible or other suitable pipe and a
suitable nozzle.
The action of the pump is as follows:-
On drawing the outside or working cylinder e upwards the valve h is closed and
the valve g opens, thus drawing water from the cistern or vessel a into the inside
or fixed cylinder c, and on the downward or return stroke the valve g is closed and
the water is compressed or forced_through_the valve into the air chamber b and
out through the delivery pipe d. It will be evident that since both the air
chamber 6 and outer or working cylinder e are closed at the top there will be a
cushion of compressed air both in the air chamber 6 and also in the upper part
of the outer or working cylinder, whereby the jet of water issuing from the
nozzle will be continuous and can be thrown to a great height.
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 :-
The combination with a portable cistern or vessel to contain water of a fixed
inner cylinder open at top and bottom an outer cylinder working thereon with a
closed top, an air vessel surrounding the inner or fixed cylinder and fitted with
valves and a delivery pipe, all constructed and arranged substantially as hereinbefore
described and illustrated by the drawings annexed.
Dated this 22nd day of April 1896.
