IMPROVEMENTS
IN HAND-FIRE-
My Invention has reference to that class of pumps known as hand fire engines
and has for its object the production of a continuous or nearly continuous stream
of water from the jet after a few strokes of the pump piston. Also the means of
readily connecting and disconnecting the said pump to a tank or other suitable
reservoir
And my invention consists in the first place in constructing the pump in the
following manner
A metal pipe or tube serves as the barrel of the pump within which is another
smaller pipe or tube which serves as a piston rod and air chamber. A. suction
valve is fitted to the bottom of such barrel, also there is a hollow piston fitted
with a spherical valve which is inserted between the piston and the piston rod.
There is a chamber at the top of the barrel which serves as a guide to the piston
rod and the hose to discharge the water is secured to a suitable opening on one side
of this chamber.
. On the first upstroke of the piston the suction valve at the bottom of the
barrel will be opened and water will be drawn into the pump. On the down-
stroke the suction valve will be closed and the spherical valve in the piston will
be opened and will cause the water to rise from the part of the barrel below the
piston into the space between the barrel and the piston rod. A few strokes will
then cause the said space to be filled and on continuing to work the piston part of
the water in the pump will be forced into the hollow piston rod thus compressing
the air contained therein and by this means a continuous or nearly continuous jet
of water will be discharged from the pump

separately (as for instance for watering flowers) or in connection with a tank or
reservoir for extinguishing fire or other purposes where a larger supply of water is.
needed.
For this purpose I provide the pump barrel with a conical collar against
which a spring presses such spring being fastened to the tank When the pump is
required to be fixed into the reservoir or tank it is forced downwards and the
spring will then be pressed backwards by the conical collar and when this collar is
passed will start back against the barrel above the collar and thus hold the pump
in place. In order to release the pump the spring is arranged with a projection
by which it can be pulled back away from the barrel so as to enable the pump to
be taken out of the tank or reservoir, such tanks or reservoirs above referred to
being fitted as may be necessary for this purpose.

"IMPROVEMENTS IN HAND FIRE-
My Invention has reference to that class of pumps known as hand fire engines

In the second place it may be desired to use the pump so constructed either
separately (as for instance for watering flowers) or in connection with a tank or
reservoir for extinguishing fire or for other purposes where a larger supply of
water is needed. For this purpose I provide the pump barrel with a conical
collar against which a spring presses such spring being fastened to the tank. When
the pump is required to be fixed into the reservoir or tank it is forced downwards
and the spring will then be pressed backwards by the conical collar and when this
collar is passed will start back against the barrel above the collar and thus hold
the pump in place.
In order to release the pump the spring is arranged with a projection by which
it can be pulled back away from the barrel so as to enable the pump to be taken
out of the tank or reservoir such tanks or reservoirs above referred to being fitted
as may be necessary for this purpose.
Having thus stated the nature of the said Invention I will proceed to describe it
more particularly by the aid of the accompanying drawings.
DESCRIPTION OF THE DRAWINGS
Fig 1 is a side view of the band fire engine partly in section Fig: 2∙is an
enlarged section of part of the pump of the hand fire engine.
The pump portion of the fire engine consists of a metal pipe a a forming the
barrel another tube e e within this pipe being the hollow piston which is filled with

page_text: rising too far in the pipe a a by two projecting arms as shewn (Fig 2) C is the
hollow piston with a spherical valve H is the waste water chamber acting also as
a guide for the piston è e and the hose for distributing the water is screwed or
fixed to such Chamber.
When the piston C is drawn upwards the valve F will open and admit water
into the pump.
On forcing the piston C down again the valve F will close and the piston valve
will open to make the water rise from the barrel below the piston into the chamber
between: the pipe a a and the piston rod e e-A few strokes of the piston will
suffice to entirely fill the said Chamber and on continuing to work the piston part
of the water will be forced into the hollow piston rod C compressing the air therein
contained whereby a continuous or nearly continuous jet is obtained.
In Fig 2 the engine is shewn fitted into the tank or reservoir B by means of
the spring c and conical collar b hereinbefore described The handle for carrying
the apparatus is shewn at n.
Having thus described the nature of the said Invention and in what manner the
same is to be performed I hereby declare that what I claim as of my Invention is
First The construction of a hand fire engine whereby a continuous or nearly
continuous stream of water may be produced from the jet substantially as and for
the purposes herein before described
And secondly the combination and application of such hand fire engine to a
tank or reservoir in the manner and for the purposes substantially as hereinbefore
described
In witness whereof I the said Siegfried Bauer have hereunto set my hand and
seal this twelfth day of May in the year of our Lord One thousand eight hundred
and eighty four.
