I ALFRED TOZER, of the Chief Fire Station, Jacksons Row, Manchester in the
County of Lancaster, Superintendent of the Manchester Fire Brigade, do hereby
declare the nature of the said invention, to be as follows:-
My invention relates to the pipe used for directing the jet of water or liquid for
extinguishing fires and other purposes commonly termed the "branch" and consists
in forming it in one piece shaped and arranged so that two hose pipes are or may
be connected to it at one end to take the supply of water or liquid from two hose
pipes and discharge it from the same nozzle which is screwed on the discharge end
of the "branch."
That end of the "branch" connected with the hose pipes is made to fork into
two pipes the ends of which are prepared or formed to fit the couplings on the
hose pipes, those known as "Morris' Patent hose pipe couplings" being preferred.
With my improved "branch" (within which the fluid from both hose pipes
gradually unites) the discharged fluid is thrown to a much greater distance, with
the same pressure of supply than by any mode hitherto used by which two hose
pipes are arranged to supply the same " branch."

other Fluids for Extinguishing Fires and other Purposes.
I ALFRED TOZER, of the Chief Fire Station Jacksons Row, Manchester in the
County of Lancaster, Superintendant of the Manchester Fire Brigade 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:
My invention relates to the pipe used for directing the jet of water or liquid for
extinguishing fires and other purposes commonly termed the "branch," and consists
in forming it in one piece shaped and arranged so that two hose pipes are or may
be connected to it at one end to take the supply of water or liquid from two hose
pipes and discharge it from the same nozzle which is screwed or otherwise attached
on the discharge end of the "branch."
"
That end of the branch connected with the hose pipes is made to fork into two
pipes the ends of which are prepared or formed to fit the couplings on the hose
pipes, those known as "Morris Patent hose pipe couplings" being preferred.
With my improved branch (within which the fluid from both hose pipes
gradually unites) the discharged fluid is thrown to a much greater distance with
the same pressure of supply, than by any mode hitherto used by which two hose
pipes are arranged to supply the same "branch."
Fig. 1 is a side elevation, and fig. 2 is a longitudinal section taken between the
fork and at a right angle to the plane of fig. 1.
Fig. 4 is a side elevation and fig. 3 a longitudinal section corresponding
respectively to figs. 1 and 2, but showing the discharging nozzle secured in the
branch by a spring catch.
Fig. 5 is a view corresponding to fig. 1, but combined with screw unions for
connecting the hose pipes to the forked pipes of the "branch."
In the modification shown by figs. 1 and 2, the branch a is formed as shown; at
one end is prepared to receive the jet nozzle b which is screwed on, at the other
end which forks into two pipes a¹, it is prepared with a junction similar to those
used for Morris Patent hose pipe couplings, which are shown connected therewith
by figs. 2 and 4.
Fig. 5 shows the "branch" with the screw or jet nozzle and screw unions d for
attaching the hose pipes, one forked pipe a being made longer than the other to
keep the two pipes as close as possible while giving space for the unions, to screw
on the hose pipes.
I prefer the hose pipe couplings shown in figs. 2 and 4 because the two hose
pipes can be brought practically close together, the two pipes a¹ thus uniting at a
small angle as near as possible in the direct line with the longitudinal axis of the
branch (a).
The hose couplings shown in figs. 2 and 4 are formed as shown.
That part c of the coupling formed on the "branch" a, enters the other part (c¹)
attached to the hose pipe x. c2 is the index rubber packing ring placed in a recess
in the part c¹ (shown in section in figs. 2 and 4.

page_text: A lip of this india rubber packing ring comes inside and. against a bevel or
internal cone formed in the interior of the end of the part c.
care bolts fitted to slide in a tubular projection c* from the part c¹.
Each bolt ca has a stem c³ which slides through a hole in a bush screwed into
the end of the tube c', and there is a helical spring c round the stem that abuts
against a shoulder on the sliding bolt at one end and against the said bush at the
other end.
There is a tubular handle c' which slides on the tube c' which handle has in its
interior a disc with a hole through its centre for the end of the stem c³ of the bolt
to pass through, the end of which stem is screwed for a nut c', which thus connects
the stem c of the bolt and sliding handle c7 the outer open end of which is closed
by a disc c screwed into it.
By pulling out both handles c7 simultaneously the two parts of the coupling
are separated the spring bolts c³ catch automatically when the two parts of the
coupling are forced together.
In the modification shown by figs. 3 and 4 the jet nozzle b¹ is secured by a spring
catch, the coupling being similar to that for the hose pipes.
c is the india rubber packing ring, c³ the sliding bolt, c' the sliding handle.
The tubular part is not solid with the branch a but is screwed on to a
projection from it as shown.
There is a conical tube a' attached to each "branch" a into which the end of a
rod e can enter there being a hook e¹ on the rod that passes between the fork of
the branch a as shown in fig. 3-There is also a projection es from the rod to come
against the side of the "branch" as shown.
"
This rod e and hook el is the upper end of a stand e* shown by fig. 6 a side and
fig. 7 a front view; employed to sustain and direct the "branch a when in use.
The forked part e³ at the lower end of the stand rests upon the ground when in
use and the fire-man holds the stand by means of the handles e-Thus the weight
of the branch a and its connected hose pipes, and the reaction of the discharging
jet is sustained by the stand which the fire-man can move to direct the jet as
required.
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.. The construction or combination of "branch" pipes for connection with two
hose pipes as herein before described and illustrated by the drawings.
2. The combination of "branches" for connection with two hose pipes with a jet
nozzle as illustrated by figs. 3 and 4, and with hose pipe couplings as illustrated by
figs. 2, 3 and 4, substantially as herein before described.
Dated this twenty ninth day of September 1886.
