AN IMPROVED, PORTABLE PUMP, FOR OIL AND OTHER LIQUIDS
Year: 1885

page_text: We THOMAS WOLSTENHOLME, Clerk, of 11 Albert Place, Trafalgar St, and
CHARLES GAUL, of 30 Longside Lane, both of Bradford in the County of York,
do hereby declare the nature of our invention for AN IMPROVED, PORTABLE PUMP,
FOR OIL AND OTHER LIQUIDS, to be as follows :—
This pump is constructed by placing one tube inside another, a piston is fixed to
the bottom of the inner tube, which acts as the piston rod, which by pressing down
forces the liquid up the interior of the tube, acting as piston rod. Near the top is
fixed a connection, inside which is placed a valve for keeping out the air. The
top of the tube or piston rod is provided with a button stopper, which answers the
purpose of forming a knob, making the end of the tube or piston rod secure.
the T connection projects a pipe curved in the form of a tap, and in this apparatus
dispenses with the use of a funnel, in supplying to bottles, or any such vessels.
From
Inside the pump barrel, is provided a spring, fastened to the piston, and top of
the pump barrel for the purpose of giving the piston rod its upward movement.
The top of the pump barrel is made slightly conical, for the purpose of fitting in
bung holes of casks, bottle necks, or any other such vessels, the pump is also pro-
vided with a funnel, for the purpose of conveying any overflow, or waste, back into
the receptacle.
•
This pump is intended to dispense with use of taps, and consequent loss from
leakage &c.
We THOMAS WOLSTENHOLME Clerk of No 11 Albert Place, Trafalgar Street and
CHARLES GAUL Engine Tenter of No 30 Longside Lane both of Bradford 'in the
County of York do hereby declare the nature of our invention for AN IMPROVED
PORTABLE PUMP, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
This Improved Portable Pump is intended to insert into receptacles of any kind
where taps are at present used and for this purpose is constructed by inserting one

page_text: tube which acts as piston rod in another larger tube allowing an easy withdrawal
of the liquid and also of the pump when the receptacle is empty.
In order that our invention may be better understood we proceed to describe by
reference to the accompanying drawings A. is the pump barrel which is provided
with a valve or clack F. B. is the piston rod, with delivery pipe combined. C1 is
the piston which is fitted on the end of the delivery pipe. D is a ball valve or
clack which keeps the pipe charged with liquid and also keeps out the air. E is a
spiral spring which is fastened to the top or cover of the pump and to the end of
the piston rod I is a T connection for connecting the curved delivery pipe J.
When the pump is inserted in a vessel containing liquid the piston rod is pressed
down by the button K. which expands the spring E. and acting on the liquid in the
barrel, A. forces it past the valve D up and out of the delivery pipe J. On releasing
or easing the piston rod B. the spring contracts and withdraws the piston C1 which
causes the valve or clack F to open and admits a fresh supply of liquid into the
pump barrel above the balls D and F are pins or guards to keep the balls in
position.
We also provide a receiver G. which conveys any overflow or droppings into the
top part of the pump barrel, on the piston being returned forces the liquid so
conveyed through the two holes H H back into the receptacle. The receiver is
also provided with a perforated plate M to keep out dust or sedement A hollow
glass ball N placed at the bottom of the receiver G. which will float and allow the
liquid to flow into the barrel but afterwards close the hole is for the purpose of
preventing evaporation.
The top of the pump barrel is made slightly conical so as to allow its fitting
bungholes of barrels and bottle necks.
The position of receiver may be altered to suit any kind of vessel.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
1. The combination of delivery pipe and piston rod.
2. The spring motion for returning the piston.
3. The receiver for collecting and conveying the liquid as shown herein.
4. The combination of above claims substantially as set out in the body of the
specification.
