Improvements in Spirit Pumps,
We, GEORGE HENRY TIPPING, of Glengall Tavern, High Street, Peckham,
London, S.E., Licensed Victualler, and JoN THOMAS WOODWARD, of 29, Radnor
Street, Peckham, London, S.E., Engineer, do hereby declare the nature of this
invention to be as follows:.
This invention relates to vacuum spirit pumps, such as are use by licensed
victuallers and others, for drawing the air from spirit vats, kegs and the like,
so as to produce the flow of spirit from the reservoir or reserve stock through
the pipe or pipes into the said vats, kegs or casks, when same has been temporarily
stopped by admission of air.
This improved spirit pump is of syringe like appearance and is provided at is
outer end with an india rubber lined, or other suitably formed adjustable tap-
union or socket.
This union is made to fit tightly over any of the tap nozzles of spirit vats and
the like.
Between the union and the body or cylinder of the pump a non-return valve
is fitted to allow the air or spirit in the vat, keg, or the like to enter the pump
when the plunger is withdrawn but prevent same from re-entering the vat when
the plunger is thrust back. The plunger is preferably fitted with a cup leather
the convex side of which faces the handle of the pump.
Close to the handle end of the pump a suitably shaped oulet is provided for
the escape of air or spirit, when the pump is in use, or for the pump to drain
through after use. The handle end of the pump is preferably provided with a
stuffing box or gland for the plunger rod to work through.
A hook or other suitable means for attaching a cup or other receptacle below
the outlet may be provided, or a can or receptacle may be formed as a part of
the pump.

Improvements in Spirit Pumps,
We, GEORGE HENRY TIPPING, of Glengal Tavern, High Street, Peckham,
London, S.E., Licensed Victualler, and JOHN THOMAS WOODWARD, of 29, Radnor
Street, Peckham, London, S.E., 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 vacuum spirit pumps, such as are used by licensed

page_text: victuallers and others for drawing the air or gas from spirit tubes leading from
vats, kegs and the like so as to cause the spirit to flow from the reservoir or
reserve stock through the pipe or pipes into and through the delivering taps
when the flow has been temporarily stopped by admission of air.
This improved spirit pump is of syringe like appearance and is provided at its
outer end with an india rubber lined or other suitably formed adjustable tap,
union or socket.
This union is made to fit tightly over any of the nozzles of spirit taps and the
like.
Between the union and the body or cylinder of the pump a non-return valve
is fitted to allow the air or spirit in the pipe to enter the pump when the plunger
is drawn back but prevent same from re-entering the pipe when the plunger is
thrust forward.
The piston is preferably fitted with a cup leather of rubber or any suitable
substance, the concave side of which faces the handle of the pump. Close to
the handle end of the pump a suitably shaped outlet provided for the escape
of air or spirit, when the pump is in use or for the spirit to drain through after
use. An air inlet is also provided to admit air to the top of the barrel.
The handle end of the pump is preferably provided with a stuffing box or
gland for the piston rod to work through.
A hook or other suitable means for attaching a cup or other receptacle below
the outlet may be provided, or a can or receptacle may be formed as a part of
the pump.
We will now describe the invention with reference to the accompanying draw-
ings in which :-
Fig. 1 shows an outside elevation of one form of the pump.
Fig. 2 shows a longitudinal section of same.
is the barrel of the pump, inside which works the piston b, attached to the
rod c which passes through the usual stuffing box and gland at x and is provided
at its outer end with any convenient handle c¹.
The piston is preferably formed by a cup leather or rubber or other suitable
substance held between metal plates; the leather or rubber being flexible allows
air to pass it in one direction, thus forming a non-return valve.
At the outer end of the pump barrel is a small vertical chamber d in which
is a non-return valve e, e¹ is the valve seating and the valve is normally kept
upon its seat by the spring f coiled around the the valve pin f¹. The screw
cap is centrally recessed to receive the lower end of the valve pin.
When the pump is to be brought into use, the upper end of the chamber d,
is fitted on to the nose of a cock fixed in or on the pipe from which air is to be
exhausted, and the joint is made air tight by screwing in the cap 9 which com-
presses and expands the rubber ring inside the cap between it and the
shoulder, against the nose of the cock. The pump may thus be used in con-
junction with taps of various sizes.
When the piston is drawn backwards the air (with or without some of the
spirit) will be drawn into the pump barrel through the valve e and when the
piston returns the air and spirit not being able to return will be forced past the
piston and be expelled through the outlet h in the barrel of the pump a, by
the next back stroke of the piston. To facilitate this action and enable any
spirit which may find its way into the pump to drain off quickly a small ventilat-
ing air tube is attached with an inlet on the upper side of the barrel.
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. A hand-pump or syringe for withdrawing air from pipes used to convey
spirit or other liquor from the cask or receptacle in which it is stored, said pump

page_text: consisting of a barrel with outlet and air inlet, a piston, and an adjustable socket,
with non-return valve, as herein described and set forth.
2. In a hand pump or exhaust syringe for removing air from spirit tubes and
like purposes the combination of an adjustable socket and parts d, a non-return
valve e within said socket, and elastic piston head b, also forming a second non-
return valve in barrel, the barrel a with outlet h and ventilating pipe i with or
without the gland, as herein described and set forth.
