PROVISIONAL SPECIFICATION.
Improved Appliance or Can for Use in Extinguishing Fires.
A communication by GEORG MÜLLER, of The "Rehleseiler," in Kaufbeuren,
Swabia, in the Empire of Germany.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This fire extinguisher consists of a metal vessel which may be square at the
bottom and gradually diminishes towards the top to a narrow but broad discharge
opening or slit. The vessel has an opening, which may be closed by means of a
slide, to enable it to be filled with water, and it also has two handles.
The vessel is filled with water up to the side opening and the slide is then pushed
to, and then by simply throwing the vessel forward a broad jet may be thrown for
a distance of about 10 metres. The narrow discharge opening only allows of a
certain quantity of water escaping at each jerk and consequently with a single
filling, according to the size of the vessel and that of the opening, about
20 sprinklings may be made, whilst with an ordinary fire bucket, or other like
vessel, the contents almost all escape at the one throw besides which they only
carry a short distance.
A discharge slit having a four cornered mouth gives a continuous, long jet or
stream, whilst a conically shaped slit yields a broader and shorter jet.
Dated this 18th day of September 1893.

page_text: provided with an elastic washer, prevents the water from escaping from the point
where it is turned back, when the apparatus is in use.
Instead of making the upper part of the vessel with a covering piece or cap, the
vessel may have an opening which may be closed by means of a slide d, shown in
dotted lines, to enable it to be filled with water, and the opening then closed.
In order to use the vessel, it is filled with water up to the hinge i or to the side
opening d and the opening c is closed, and then, by simply throwing the vessel
forward, a broad jet may be thrown for a distance of about 10 metres. The
narrow discharge opening only allows of a certain quantity of water escaping at
each jerk, and consequently with a single filling, according to the size of the vessel
and that of the opening, about 20 sprinklings may be made, whilst, with an ordinary
fire bucket or other like vessel, the contents almost all escape at the one throw,
besides which they only carry a short distance.
A discharge slit having a four-cornered mouth gives a continuous, long jet or
stream, whilst a conically shaped slit yields a broader and shorter jet.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
An appliance or can for use in extinguishing fires, consisting of a long vessel
closed at the bottom and gradually tapering to a discharge opening or slot,
provided with handles and a filling opening, which vessel, when filled with water, is
vigorously jerked forward, and, in consequence of the pressure of the water on the
narrow discharge slot, a broad continuous jet of water is produced; substantially
as herein before described and shown on the accompanying drawing.
