page_text: I, GUSTAVUS ADOLPHUS JOHN SCHOTT Manufacturer of West End Mills Richmond
Road Bradford in the County of York, do hereby declare the nature of this invention'
to be as follows:-
This Invention relates to improvements in that class of fire engines, in which
a combined lift and force, or suction and force pump giving a continuous jet is
used in conjunction with a tank containing the liquid to be pumped on to the
fire and my improvements more particularly relate to portable fire extinguishing
apparatus They are however likewise applicable to larger apparatus.
The object of my invention is to provide for sudden emergencies by keeping
such apparatus in a constant state of readiness for use- -To effect this I proceed
as follows-I attach to the outside of the tank a combined suction and force pump
worked in any convenient manner and enclosed in a suitable casing-Such pump is
fitted with a waste receiver.
The suction pipe is divided into two branches, one branch entering the tank and
the other branch is fitted with a suction hose-At the point of bifurcation a two
way cock is inserted by which either branch can be placed in communication with
the pump as desired. A suitable mouth piece and nozzle are screwed to the pump
while the tank is provided with a inovable lid and also with a strainer to prevent
the pump getting choked.
The bottom of the tank may be of any convenient form.
Or instead of a suction and force pump and bifurcated pipe as above described
I employ a combined lift and force pump similar to those in use for garden syringes
and fit it inside the tank.
I likewise provide the tank with a suitable chamber for the storage of chemicals
to be used in extinguishing fire such chamber being fitted in any convenient posi-
tion and otherwise arranged to allow of its contents being readily discharged
through the pump-A suitable reserve tank may likewise be fitted to the engine-
By these improvements the engine may always be kept in readiness at the same
time that it can in this condition be used for watering gardens and other such like
purposes while in the case of any sudden emergency it is immediately available as
a fire extinguisher..

page_text: I, GUSTAVUS ADOLPHUS JOHN SCHOTT Manufacturer, of West End Mills Richmond
Road, Bradford in the County of York 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 more particularly to improvements in portable fire
extinguishing apparatus which apparatus is also applicable for watering plants
and other like purposes and has for its object to increase the utility and convenience
of such apparatus-Such improvements are however likewise applicable to larger
apparatus.
In the accompanying drawings Fig. 1 shews a view of a portable fire extinguishing
apparatus fitted with my improvements next hereinafter described. Attached to
the outside of the tank a is a combined suction and force pump a¹ worked in any
convenient manner and enclosed in a suitable casing b to preserve it from injury-
This casing is furnished with a door c so as to afford ready access to the mechanism
-Such pump is fitted with a waste receiver d provided with a waste plug d' while
the suction pipe thereof e is divided into two branches e¹, e-The branch e¹ enters
the tank while the branch e2 is fitted with a suction hose f-A two way cock g is
inserted in the suction pipe e at the point of bifurcation by means of which cock
either branch can be placed in communication with the pump as desired and such
pump is provided with a delivery hose fitted with a suitable mouth piece and
Dozzle The tank is provided with a movable lid and also with a strainer in
order to prevent the pump getting choked.
The bottom of the tank a is so formed as to afford a convenient platform m
whereon the operator may stand when working the pump.
A modification of this arrangement which is shewn at Fig. 2 of the accom-
panying drawings consists in dispensing with the suction and force pump and
substituting therefor a combined lift and force pump (1) similar to those in use
for garden syringes-Such pump is fitted inside the tank-The pump may be made
either fixed or detachable-If detachable I fit the tank with a socket or sheath (2)
wherein the pump can be placed when not in use.
Another feature of this modification consists in fitting the pump with a cylindrical
or other suitably shaped metal box (3) wherein chemical compounds suitable for
extinguishing fire may be stored-Such box consists of an inner and outer casing
fitting loosely into each other-The outer casing is open at the bottom and closed
at the top while the inner casing is perforated and is closed at the bottom and
open at the top so that when the box is immersed as presently described the water
euters such inner casing and dissolves the chemical charge contained therein-The
pump passes through the centre of such metal box and in order to keep the box
and its contents dry until required for use the box is held in position by a lonk
and eye (4) or other equivalent mechanical device placed in any convenient posi-
tion Upon releasing such fastening the box slides down the pump to tlie bottom

page_text: of the tank (as indicated in dotted lines in Fig. 2) thus allowing the water to enter
the box and dissolve the chemical charge therein.
By thus providing for the box being kept in reserve until required for use-the
engine may when desired be used as a garden engine and for other similar purposes
at the same time that it is ready for immediate use in case of any sudden alarm
of fire.
When the pump is made detachable I fit the same with a toothed collar (5)
which takes into a recessed flange (6) formed round the top of a socket holder (7)
fixed to the tank in any convenient position-This socket holder serves to steady
the pump and when the toothed collar of the pump is locked into the flange of the
holder the pump is firmly held in position.
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
1° Fitting a portable fire extinguishing apparatus with a suction and force
pump a casing b, door c-waste receiver d-waste plug d-bifurcated suction
pipe e-suction hose f-two way cock g delivery hose h with mouth piece and
nozzle i movable lid k-strainer -and platform m all constructed, combined
arranged and fitted substantially in the manner and for the purposes herein before
specified and shewn.
2° As a modification of the arrangement first described and claimed-Fitting
a portable fire extinguishing apparatus with a combined lift and force pump (1)—
socket or sheath (2) chemical chamber (3)-hook and eye (4) or other equivalent
mechanical device-toothed collar (5) recessed flange (6) and holder (7) all con-
structed combined arranged and fitted substantially in the manner and for the
purposes hereinbefore specified and shewn.
3° The application of my improvements to fire extinguishing apparatus of a
larger size.
