IMPROVEMENTS IN HAND FIRE-EXTINGUISHERS
Year: 1885

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent
Agents, Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of my invention for "IMPROVEMENTS IN HAND FIRE-EXTINGUISHERS "
to be as follows:-
This invention relates to hand fire-extinguishers with which a liquid charged
with gases for extinguishing fire is employed.
The said invention comprises a cylindrical tube or case (made of tin or other
suitable material) provided, near the end out of which the liquid is discharged,
with a partition which has area sufficient to prevent the liquid from being spilled
out of the tube by any sudden movement in removing the stopper, but which has
apertures enough to permit the liquid in sufficient quantities to be thrown upon a
fire to extinguish it.
The stopper is fastened or soldered firmly enough to the tube or case to sustain
the weight thereof and its contents, but not so firmly but that a sudden pull or
jerk will easily remove it. A wire loop is attached to the stopper by which the
tube and its contents are suspended from a staple or strong nail driven into
the wall.
The tube or case is preferably about twenty inches long and two inches in
diameter. When required to be used, the lower portion of the tube is grasped by
the hand, and the tube is quickly moved downward or jerked, whereby the stopper
is readily removed,
In carrying the said invention into practice I employ a tube, which I prefer to
make of tin and of the size hereinbefore stated. Within this tube is a polygonal
partition or diaphragm which serves to prevent the liquid from coming out of the
tube in too large quantities, and to distribute the contents of the tube over a large
surface. Apertures around the same permit the liquid, in suitable quantities, to be
ejected onto a fire.
The ends of a wire loop are passed through the stopper of the tube and are then
bent at right angles, and drawn apart and soldered to the under side of the stopper,
thus distributing the sustaining power of the stopper over its entire surface; but

page_text: the loop may be fastened in any other convenient and sufficient manner. When
required to be used, the tube is grasped by the hand and is quickly moved down-
ward, the apertures around the partition causing the tube to give or wrinkle, thus
breaking the solder around the stopper, enabling it to be easily removed.
The stopper is made of tin, or any other suitable material which will prevent
the escape of the liquid, and is secured tightly enough to the tube by being
soldered, to support the weight of the tube and its contents; and, as above stated,
it is provided with a wire loop by means of which the extinguisher is suspended
from a staple till required for use. When the tube is pulled the stopper is left
suspended from the staple by the wire loop. The contents of the tube are sprinkled
or showered on the fire, the action being kept up with vigor, and any number of
tubes used that may be required to entirely extinguish it.
This hand extinguisher is designed for smaller or incipient fires.
The liquid
used is such that, by its contact with a heat of about 150° Fahrenheit, gases are
generated which extinguish fire by absorbing the oxygen.

I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co, Patent
Agents Southampton Buildings, in the County of Middlesex do hereby declare
the nature of my invention for "IMPROVEMENTS IN HAND FIRE-EXTINGUISHERS"
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 to hand fire extinguishers with which a liquid charged
with gases for extinguishing fire is employed.
The said invention comprises a cylindrical tube or case made of tin or other
suitable material and provided near the end out of which the liquid is discharged
with a partition which has area sufficient to prevent the liquid from being spilled
out of the tube by any sudden movement in removing the stopper, but which has
apertures large enough to permit the liquid in sufficient quantities to be thrown
upon a fire to extinguish it.
The stopper is fastened or soldered firmly enough to the tube or case to sustain
the weight thereof and its contents, but not so firmly but that a sudden pull
or jerk will easily remove it. A wire loop is attached to the stopper, by which
the tube and its contents are suspended from a staple or strong nail driven into
the wall.
The tube or case is preferably about twenty inches long and two inches in
diameter. When required to be used, the lower portion of the tube is grasped by
the hand, and the tube is quickly moved or jerked downward; the stopper is thus
readily removed.

Figure 1 is a perspective view of a hand fire extinguisher embodying my
improvements.
Figure 2 is a vertical section of the tube, showing the position of the partition,
which is of polygonal shape, and the manner in which the wire loop is attached to
the stopper.
Figure 3 is a top view of the polygonal partition, showing the apertures around
the same.
Figure 4 is a perspective view of the stopper and wire loop, showing the
preferable manner of attachment of the latter to the under side of the stopper.
Figure 5 is a front elevation of the fire extinguisher.
Similar letters refer to similar parts in all the drawings.
A represents the tube, which I prefer to make of tin and of the size hereinbefore
stated. D is the polygonal partition or diaphragm which serves to prevent the
liquid from coming out of the tube in too large quantities, and to distribute the
contents of the tube over a large surface; a a a are apertures around the said
partition to permit the liquid in suitable quantities to be ejected onto a fire.
The ends of the wire loop Care passed through the stopper B, and are then bent at
right angles, and drawn apart and soldered to the under side of the stopper B, thus
distributing the sustaining power of the stopper over its entire surface; but the loop
may, if desired, be fastened in any other convenient and efficient manner. When the

page_text: apparatus is required to be used, and the tube A is grasped by the hand and quickly
moved downward, the apertures a, a, a cause the said tube to give or wrinkle, thus
breaking the solder around the stopper B, and enabling it to be easily removed.
The stopper B, is made of tin, or any other suitable material which will prevent
the escape of the liquid, and is secured tightly enough to the tube A, by being
soldered, to support the weight of the tube and its contents; and, as above stated,
it is provided with a wire loop C, by means of which the extinguisher is suspended
from a staple E, till required for use. When so required, the lower end of the
extinguisher is grasped by the hand and by a quick movement or jerk is drawn
from the stopper B, leaving the latter suspended from the staple E, by the wire

being kept up with vigor, and any number of tubes are used that may be required
to entirely extinguish the fire.
Jann
This hand extinguisher is designed for small or incipient fires. The liquid
used is such that, by its contact with a heat of about 150° Fahrenheit, gases are
generated which extinguish fire by absorbing the oxygen.
The essential feature of my invention is the construction of a hand fire-
extinguisher (with which a liquid charged with gases is employed) consisting of
a tube closed at both ends and provided with a partition of polygonal shape. As
it is apparent that such an extinguisher may be used without employing all the
special features above mentioned, as for instance without the loop, I do not wish to
be understood as limiting myself to special forms or details of construction.
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
First. A hand fire-extinguisher with which a liquid charged with gases is
employed, comprising a tube provided with a partition of polygonal shape, and
having a closed bottom and a stopper at, or near, the top, secured by a fusible joint,
substantially as described.
Second. In hand fire-extinguishers with which a liquid charged with gases is
employed, the combination of a tube provided with a partition of polygonal shape,
and a stopper provided with a loop, substantially as described.
Third. In hand fire-extinguishers with which a liquid charged with gases is
employed, the combination of the tube A, provided with the partition D of
polygonal shape, with a stopper B and loop C whereby the tube is closed,
suspended, and opened, substantially as described.
