in the County of Lancaster, for an Invention of "IMPROVEMENTS FOR A
VESSEL IN WHICH CARBONIC ACID GAS IS GENERATED, AND ALSO IMPROVEMENT
IN THE FORMATION OF A HOSE REEL COMBINED, TO BE USED FOR THE PURPOSE
OF EXTINGUISHING FIRE."
COMPLETE SPECIFICATION filed by the said Jacob Henry Radcliffe at the
Office of the Commissioners of Patents on the 10th May 1880.
JACOB HENRY Radcliffe, of 12, Marlborough Street, Oldham, in the County of
Lancaster. "IMPROVEMENTS FOR A VESSEL IN WHICH CARBONIC ACID GAS IS
GENERATED, AND ALSO IMPROVEMENT IN THE FORMATION OF A HOSE REEL
COMBINED, TO BE USED FOR THE PURPOSE OF EXTINGUISHING FIRE"
I construct a vessel of tinned iron or steel sufficiently strong to withstand great
pressure, and may be made to any required size, as shewn, Fig. 1, and Fig.
No. 2, in which vessel I generate carbonic acid gas by combining the necessary
chemicals within an air tight vessel, namely, sulphuric acid, bi carbonate of soda,
and water, to be used for the purpose of extinguishing fire, and herein described.
Fig. No. 1 represents my Invention which forms itself into a hose reel and fire
extinguisher combined upon a stand, which may be fixed to the floor if required, or
to a wall, or by having the stand K of sufficient weight to cause it to stand erect
when the hose pipe E is pulled off with great force; this fire extinguisher I affix a
foot pin at the bottom, as shewn at Fig. 1, B, and upon which it revolves. H is a
pin which passes through the terminus of the rod J and into the knob and spindle,
upon which the fire extinguisher revolves at top; the knob and spindle is bored
sufficiently deep to allow the knob and spindle to move sufficiently up the pin H
without any impediment when the catch is removed, and the inner spring is acting
upon the spindle to move the knob up the pin. This pin H forins a centre for the
fire extinguisher to revolve upon; D represents the body of the fire extinguisher
having a long length of rubber hose pipe attached and coiled round its body with
a tap at the end; F is a break roller which acts upon the rubber hose pipe for the
purpose of preventing the rubber hose running off to quick when the tap and
pipe and rubber pipe is pulled off with great force; for use this break roller is
Din all

page_text: regulated at G by screwing or unscrewing the pins G which forms the bearing of
the break roller. Fig. 3 represents the screw cap of my Invention with an acid
vessel combined, and also my other improvements; in the screwed part of this said
cap I make a hole or holes, which when the cap is screwed into the fire extinguisher
this said hole or holes are covered by the shell of the screw cap which is fixed at.
the top of the fire extinguisher, so that when the cap and acid vessel is screwed up
the hole or holes are then covered and makes an air tight joint with the shell,
which is affixed to the fire extinguisher. The object of these is, should the
catch get moved accidently or otherwise, and the gas generated, creating great
pressure within, is to allow the escape of gas when the said screwed cap is moved
back or unscrewed partially, otherwise the great pressure of gas within might force
out the cap and acid vessel, thereby endangering the life of the person so unscrewing
the cap. Fig. 3, letter A, represents the acid vessel, which I make of pure lead or
other substance which an acid will not materially act upon; B, B, represents two
rods hung by two swivel joints at C, C, passing beyond the bottom of the acid
vessel to carry a metal bottom, which is attached to the bottom of the said acid
vessel, thereby forming two more swivel joints at D, D, by a pin passing through
the projections on the metal bottom, as shewn, Fig. 9. This swivel joint may be
made round, ecliptical, or angular, the angular point to act as a bearing as the
pivot of a pair of scales, see Fig. 12; the object of this is that when the lid is
released by moving the catch it will be a certainty for the acid vessel to capsize,
and almost impossible for the acid vessel to remain in erect position in equilibra-
tion; Fig. 4 represents the lever trigger or catch, and is affixed on the cap by a
small set pin through the hole A on the top of the cap; Fig. 5 represents the end
view of a flat spring which fits on the back of the catch or lever shewn,
Fig. 4.
Fig.
represents a wire pin which passes through the holes of the catch or lever
shewn, Fig. 4, at b and c, and one end passes a little distance into the cap to
prevent it being accidentally removed from its place; when the fire extinguisher is
charged for use I place a piece of gum paper, or seal and 'initial the same when the
fire extinguisher is charged, so that I can know whether the same has been
tampered with by any person not having authority to meddle with it, otherwise it
might be tampered with, and when required for extinguishing fire there would not
be sufficient gas to expel the extinguishing fluid with the necessary force; Fig. S
represents the cover of the acid vessel, the stem of which in this case passes through
the bridge upon which the spring rests, thereby preventing the screwed thread on
the valve spindle getting fixed in centre of the bridge with the spring, obviating
any danger of it not doing what is required through the spindle being so fixed; it
is bored and screwed down the centre, as shewn at A, to receive the spindle and
valve; Fig. 7 represents a rubber washer of a peculiar form and kind which is
pulled over the bottom of the lid of the acid vessel shewn, Fig. 8, at B, thereby
obviating the necessity of having a metal set screw to affix the rubber washer on
the bottom of the acid vessel cover; Fig. 9 represents the metal bottom which I
make considerably heavier on one side than the other, so that this part to be
attached to the bottom of the acid vessel cannot be held horizontally in equilibra-
tion, or when it is attached to the bottom of the acid vessel the acid.vessel cannot
remain perpendicular when resting upon its bearings or pivots in equilibration;
Fig. 10 represents a stud or pin to form a swivel joint when passed through the
metal bottom at D, Fig. 3; Fig. 11 represents the same with an acute angle point
at the top as the beam end of an ordinary pair of scales; Fig. 12 shews the form
of the angular stud or pin of Fig. 11; Fig. 13 represents the manner or mode most
preferable to make the bottom or bridge upon which the spring rests; Fig. 14
represents the lower part of the valve spindle which shews the means of pre-
venting the spring from getting fixed as each end of the spring passes over the
small collar shewn at A. Fig. 15 represents a steel spiral spring made of wire of
No. 11, 12, or 138 gauge, which must be sufficiently strong to lift the rubber lid
off its seat when the catch or trigger is moved. Referring again to Fig. 2

page_text: a represents two leather straps affixed to the fire extinguisher at 6 by buckles, and
c, c, represents a wire loop which is affixed upon the top of the fire extinguisher to
allow the straps to pass through to keep them straight and in order, so that when
the fire extinguisher is required they can be pulled from their position without any
impediment, and the arms passed through and taken upon a person's back for the
use of extinguishing fire. Fig. 17 represents the loop to be attached at c, c; letter
O represents a cup attached to the top of the fire extinguisher to prevent the water
and soda being spilled when being charged.
Having now described the nature of my Invention, what I claim is,―
The arrangement, application, and combination of a chemical fire extinguisher as
a hose reel and fire extinguisher..
The arrangement and application of the whole or parts described herein in the
manufacture of new fire extinguishers or the adaptation of these parts to previous
fire extinguishers.
The arrangement of the acid vessel and its action on swivel joints, as described,
also rubber washer and lid as described.
The arrangement and combination of an acid vessel which capsizes on swivel
joints attached to a screwed cap having holes in the screwed part as denoted.
The arrangement in principle and general combination, as herein set forth.
In witness whereof, I, the said Jacob Henry Radcliffe, have hereunto set
my hand and seal, this Eighth day of May, One thousand eight hundred
and eighty, A.D.
