Improvements in Extincteurs.
I, SAM FRYER, of 2, Oakfield Place, Cambridge Road, Leeds, in the County
of York, Tinsmith, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in extincteurs, and its object is to so
construct the apparatus that the glass bottle therein or connected therewith that
is usually employed, and which requires to be broken each time the extincteur
is to be put in operation,--may be dispensed with, and a reservoir provided with
a suitable valve or tap employed in place thereof.
According to this invention the main portion or body of the extincteur may
be made of any suitable. material, such as, say, metal, and of any required shape,
such as, say, cylindrical, square, elliptical, hexagonal, or other contour, and either
parallel or tapering, provided with end pieces fixed or attached thereto by any
convenient means.
In the top of the extincteur is arranged a reservoir made of any suitable
material, such as, say, metal, and arranged to project partly above the top of and
within the interior of the extincteur.
The reservoir is closed at its top and provided at, say, its lower end with a
valve and seating for the same, which may be opened and closed by any con-
venient means, such as, say, a rod passing through the reservoir and projecting
beyond its top. The said rod may work in an inner tube and be armed with a
knob or handle, and a helical spring may be coiled around the rod for retaining
the valve in a closed position. An opening with or without a screwed stopper
or cover may be provided for the admission of acid to the interior of the reservoir.
An outlet pipe, with or without a funnel shaped end at its bottom may be
provided partially within the main portion of the extincteur, and to project
through its side at a suitable distance from its top. The portion of the pipe
outside the extincteur may be provided with a nozzle or spray, or, if desired,
with a length of rubber or other flexible tubing for directing the water contained
in the body of the extincteur. The funnel shaped end of the outlet pipe is
arranged to extend down to within a short distance of the bottom of the
extincteur, and the opposite end of the pipe, which projects outside the extinc-
teur, may be provided with a cover or cap.
The body of the extincteur may, if desired, be made a fixture in any desired
position, or it may be made portable, in which case one or more handles may be
provided around or on its sides or top.

Improvements in Extincteurs.
I, SAM FRYER, of 2, Oakfield Place, Cambridge Road, Leeds, in the County
f York, Tinsmith, do hereby declare the nature of this invention and in what
anner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in extincteurs; and its object is to
construct the apparatus that the glass bottle usually employed for containing,
say, the sulphuric acid, and which bottle is placed within the extincteur, or con-
nected therewith, may be dispensed with, and in place thereof employing a
suitable reservoir or tap which is fitted to the extincteur, thus obviating the
necessity of first breaking the glass bottle, as at present, whenever the acid is
required to be liberated each time the extincteur requires to be brought into
operation, and second, of removing the broken pieces of glass from the interior
of the extincteur after each operation, and replacing another bottle filled with
acid therein.
In the drawings hereunto annexed:
Fig. 1 is a sectional elevation of an extincteur with this invention applied.
Fig. 2, a sectional elevation of reservoir constructed according to this inven-
tion.
Fig. 3, a plan of same.
Fig. 4, a part sectional elevation of a slightly modified form of reservoir.
Like parts in all the views are marked with corresponding letters of reference.
A is the main portion or body of the extincteur which may be made of any
suitable material, such as, say, metal, pot, woodite, or a combination of two or
more of them, and of any required shape, such as, "say, cylindrical, square,
elliptical, hexagonal, or other contour, and either parallel or tapering, provided
with an end piece B fixed or attached thereto by any convenient means.
Ca cap provided with projections C to form handles by which it is turned
when being screwed or otherwise fixed to the top of extincteur. C2 a leather,
rubber or other washer let into the cap for making a tight joint. D the dis-
charge pipe.
All the above described parts, with the exception of the cap C, which is con-
structed as hereafter described, are of usual and well known construction.
Instead of providing means for supporting a glass bottle, containing, say,
sulphuric acid-in the interior of the extincteur, and providing means,--such
as, a plunger working through the cap C,--for breaking the glass bottle when-
ever the acid requires to be liberated a reservoir E is provided and arranged
to form part of or to be attached to the cap C. That is to say, the cap C may
be made to form a part of the reservoir E by being cast or otherwise formed on
its exterior, or the reservoir may be made to pass through the cap, and to be
fixed thereto, say, for example, by solder or screwing or by bolts, in such a
manner that a portion of the reservoir will project above and also below the cap,
as shown in the drawings.

page_text: The reservoir E may be of any suitable material, such as lead, or other metal,
coated or covered with lead, or of porcelain, earthenware, toughened or other
glass, woodite, rubber, or the like, or a combination of two or more of them,
and it is arranged to project partly above the top of and within the interior of
the extincteur.
The reservoir E is made of any desired shape, such as cylindrical, square, or
the like, and it is closed at its top as shown, or by a stuffing box or screw or
other equivalent means and provided at its lower end with a valve or valves F,
with, say, a leather or other washer G interposed between it and the bottom of
the reservoir to form a seating for it. The valve F is opened and closed by any
convenient means, such as shown in the drawings, and consisting of, say, a rod H
passing through the top of the reservoir E and projecting beyond its top, as
shown at Fig. 2, or through a gland H' Fig. 4, fixed to the said top. The rod H
is arranged to work or pass through an inner tube I and be armed with a knob
or handle J and a helical spring K may be coiled around tie rod H for retaining
the valve F in a closed position. If desired, in some cases the inner tube I may
be dispensed with. An opening in the form of a tube L with or without a
screwed stopper or cover is provided for the admission of say, the sulphuric acid
to, the interior of the reservoir E.
All the above mentioned parts, except the washer G, when made of metal
require to be coated, or covered with a material such as lead, or equivalent
material, that will not be readily affected or damaged by the action of the acid.
In some cases, and when preferred, though not essentially necessary to the
working of the invention, to prevent the acid being forced up the tube I by the
back or other pressure in the body A of the extincteur when the acid is released
from the reservoir E, a piston N shown in dotted lines at Fig. 2, is provided
on the rod H. If desired the rod H may be made to pass through a gland or its
equivalent. In this case the rod H could be made in two parts as at Fig. 4,
arranged to be screwed together with a leather or other washer 0 interposed
between the two flanges N, N¹ formed on the ends of the two portions of rod H.
The outlet pipe D is provided with or without a funnel shaped end at its
bottom as shown, and the said pipe is arranged to be partially within the main
portion or body A of the extincteur, and to project through its side at a suitable
distance from its side or top. The portion of the pipe outside the extincteur
may be provided with a nozzle or spray (not shown in the drawings) or, if desired
by a lid or stopper held by a spring to open at a certain pressure; or a length
of rubber or other flexible tubing may be fixed to said pipe D for directing the
water contained in the body A of the extincteur on to the fire:
The funnel shaped end of the outlet pipe is arranged to extend down to within
a short distance of the bottom of the extincteur, and the opposite end of the
pipe, which projects outside the extincteur, may be provided with a cover or
cap or any suitable apparatus as described.
The body A of the extincteur may, if desired, be made a fixture in any desired
position, or it may be made portable, in which case one or more handles (not
shown in the drawings) may be provided around or on its sides or top.
The working of the apparatus is as follows:
The body A is charged with the liquid usually employed in this class of
extincteur, which liquid consists of water, previously mixed with soda, or the
required-quantity of soda having been placed in the body A of the extincteur
water is admitted to the interior of the said body A up to about three fourths
of its height, and the sulphuric or other suitable acid having been placed or
poured into the reservoir E, the valve G is opened by pressing down the rod I
and the acid allowed to drop or fall from the reservoir E into the water mixed_
with soda.
The chemical combination then set up, generates gas, and the pressure thus
formed within the body A in the space between the level of the water in the said
body A and its top creates the necessary pressure for, first, charging the water

page_text: with a quantity of gas, and then for forcing the water downwards and up the
outlet pipe D, and from thence it can be directed and discharged as desired.
The reservoir E may be filled with acid through tube L as frequently as
desired, after the valve G has been closed by spring K.
In place of the valve G, a tap may be used if so desired, and operated by the
rod H, but it is preferred to use a valve similar to that described as there is less
danger of it getting out of order.
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. In an extincteur, such as herein described, the combination with the body
of the same, of a reservoir constructed as herein described, arranged to communi-
cate with the interior of said body, and provided with a valve or valves, capable
of being operated from the outside whenever the acid in the reservoir is required
to be passed into the contents in the said body and the means described for eject-
ing the acid from the reservoir whereby the said liquid contents are forced up
and through the discharge pipe, said means also acting as a valve for preventing
any acid being forced upwards by any back pressure from the reservoir, all
arranged and as illustrated in the accompanying drawings.
2. The reservoir constructed substantially as herein described adapted to be
applied to an extincteur, and provided with a valve at its base as and for the
purposes set forth.
