PROVISIONAL SPECIFICATION.
A New or Improved Machine for Forcing or Raising Beer and other
Liquids.
I, PETER MUSHET of 113 Duke Street, Glasgow, in the County of Lanark,
North Britain, Brass Finisher do hereby declare the nature of this invention to be
as follows:-
This invention relates to a new or improved machine for forcing or raising beer
and other liquids from the casks or barrels to the tape or cocks from which the
beer or other liquid is drawn off.
The invention consists of a force pump having an inlet and outlet valve for the
admission and discharge of air. Connected to the pipe leading from the outlet
valve there is another valve to which there is attached a weighted lever. To the
end of this lever there is a switch which is connected to an electric motor, and the
motor is connected to the pump by any suitable gearing. The valve which is
connected to the pipe leading from the outlet valve breaks the circuit when the
required pressure has been obtained by raising the weighted lever.
The mode of operating the apparatus is as follows:-The weight on the lever is
regulated according to the amount of pressure required. This operation lowers the
lever thus making the electric connection and so starts the motor which actuates
the pump.
As the piston rises air is admitted into the chamber and as the piston
lowers the inlet valve closes and the outlet valve opens and the air is forced into
the cask or barrel which acting upon the upper surface of the beer or other liquid
forces it
up
the pipe leading to the tap through which the liquor is to be drawn off,
or it may be forced into a suitable receptacle for storing it.
In place of the valve for breaking the circuit I may provide a small cylinder
with a piston to raise the lever.
In place of operating the pump by an electric motor. it may be operated by a
turbine, or other water motor.

COMPLETE SPECIFICATION.
A New or Improved Machine for Forcing or Raising Beer and other
Liquids.
I, PETER MUSHET, of 113 Duke Street, Glasgow, in the County of Lanark,
North Britain, Brass Finisher, 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 :-
My invention relates to a new or improved machine for forcing or raising beer
and other liquids from the casks or barrels to the taps or cocks from which the
beer or other liquid is drawn off.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended two explanatory sheets of drawings in the
several figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a front elevation showing my improvements operated by means of
clockwork.
:..:

page_text: Figure 3 is an elevation of part of my apparatus operated by means of an electric
motor.
Figure 4 is a front elevation of the levers k and d and contact pieces i¹.
My invention consists of a force pump A having an inlet valve B (shown in
dotted lines Figure 1) and outlet valve C (also shown in dotted lines Figure 1) for
the admission and discharge of air. Geared to the crank shaft H there is a
pinion which gears into a toothed wheel J carried on the shaft. K. On this
shaft K there is another pinion L gearing into another toothed wheel M carried
on a shaft N. On this shaft N there is the drum or barrel Z carrying the cord O,
at the end of which there is the weight P. The toothed wheel M gears with the
pinion Q carried on the shaft R on which the flyer V is fixed. This train of
clockwork is carried on a suitable framing S. When the clockwork is wound up it
operates the pump A. As the piston T rises, air is admitted into the cylinder U
by the inlet valve B, and as the piston lowers the inlet valve B closes and the
outlet valve C opens, and the air is forced along the discharge pipe D and into the
cask or barrel, which acting upon the upper surface of the beer or other liquid,
forces it up the pipe leading to the tap through which the liquor is to be drawn off,
or the air may be forced into a suitable vessel for storing it.
When the air pressure is at or below the predetermined degree the weighted
lever E pressing against the upper end of the spindle a, the central part of which
is fixed to the elastic diaphragm b, the periphery being secured between the flanges
of the hollow casing c, keeps it in its normal position, but when the air pressure
rises above the predetermined degree then it acts upon the elastic diaphragm 6 and
lifts the spindle a, thus raising the weighted lever E a sufficient distance to allow
the flyer V to knock against it, thus bringing the flyer to a standstill and so
stopping the clockwork and likewise the operating of the pump. When the
pressure has been lowered to its normal degree by the drawing off of beer or other
liquid from the cask on which the air acts the diaphragm b ceases to be distended,
and so the spindle a falling to its normal position the weighted lever simultaneously
falling with it, releases the flyer V, and the clockwork is again set in motion to
operate the pump.
In place of the clockwork arrangement for operating the pump as hereinbefore
described, I may do so by means of an electric motor as shown in Figure 3. In
such case I connect the pump to an electric motor W by any suitable gearing. To
the motor 1 fix a switch which consists of two levers k, d lying side by side, and
pivoted to a bracket e and e¹. To the lower end of the lever d there is fixed a
small piece of metal fof horse shoe construction and with two small projections g, h,
the upper end of lever d having a weight i attached to it. When the pressure rises
beyond its normal degree the diaphragm 6 becomes distended and so raises the
spindle a which at same time causes the weighted lever E also to rise, and the end
of it coming against the pin h tilts over the lever k lifting it out of contact with
the metal contact pieces i¹, thus breaking the circuit as shown in hard lines
Figure 3, and stopping the motor. When the pressure is taken off the distension is
taken off the diaphragm b, and the spindle a falling to its normal position, the
weighted lever E also falls, and coming against the pin g pulls back the lever k
and so completes the circuit as shown in dotted lines Figure 3, and the pump and
motor are restarted.
It is to be understood that any other motive power might be used for operating
the pump.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The general arrangement and construction and combination of the parts
constituting the apparatus for raising or forcing beer or other liquids substantially
as hereinbefore described and shown on the annexed sheets of drawings.
2. In apparatus for raising or forcing beer or other liquids, the combination of

page_text: the hollow casing c with elastic diaphragm 6 and spindle a fixed to it which acts
upon the weighted lever E when the pressure rises beyond the predetermined
degree so that it comes in contact with the flyer V and so automatically stops the
clockwork or other motive power and operation of the pump substantially as
described and shown on the accompanying sheets of drawings.
3. In apparatus for raising or forcing beer or other liquids the construction and
arrangement of switch for making and breaking contact substantially as and for
the purposes hereinbefore described and shown on the accompanying sheet of
drawings.
