Improvements in and connected with Nozzles for the Protection of
Firemen Fighting Fire.
ALBERT WRIGHT,
Clerk, 5A, Shandon Road, Clapham Common, London,
do hereby declare the nature of this invention to be as follows:-
A spray attached to the back of nozzle for diffusing water over the fireman,
and thus preventing them from being scorched by the flames, and also to prevent
smoke from choking them. The spray to be regulated by means of a tap affixed
to same.
Improvements in and connected with Nozzles for the Protection of
Firemen Fighting Fire.
ALBERT WRIGHT, of 5A, Shandon Road, Clapham Common, London, S.W.,
Clerk, 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:-
-
This invention is an improvement in hose nozzles, having for an object to
provide means for the protection of firemen and others fighting fire in close
quarters by furnishing the nozzle with an attachment by which a small stream or
spray may be discharged upon the person it is desired to protect, and the inven-
tion consists in the novel construction of the nozzle, as will be hereinafter
described, and pointed out in the claims.
In the drawings, Figure 1 is a side view of a nozzle provided with the improve-
ment, Figure 2 is an end view thereof, Figure 3 is a detail view of the plug-
valve, Figure 4 is a detail view of a washer, and Figure 5 shows the nut for
securing the plug valve.
The nozzle A may be generally of ordinary form either as shown or otherwise
as desired, and is provided with an extension B to one side such extension
forming a valvechamber for the plugvalve C which fits the seat D in the casing B
and has a port E which may be turned into, and out of register with the port F
in the casing B such port F opening at one end into the bore G of the nozzle,

page_text: and at its other end rearwardly out of the casing B so it will discharge rearwardly
when the valve C is open. The valve C is supplied with a washer H and a
securing nut I at one end, and has at its other end the handle J. The handle J of
the valve operates within a recess K formed at one side of the valvecasing B
the handle lying wholly within the recess K, so it will not be accidentally
struck at any time in manipulating the nozzle. It will also be seen that the
handle J may be readily grasped when it is desired to turn the valve open
or shut. By this valve and construction of port I am able to discharge by the
back pressure in the nozzle a stream rearwardly from the port F on to the fireman
or other persons operating the hose and the port F is widened so it will deliver
a stream of considerable width, the force of which may be regulated by the
extent to which the valve C may be turned, and it is obvious the nozzle may
be partially rotated from time to time and otherwise manipulated to secure a
delivery or discharge of the protecting stream to any point desired by the hoseman.
By my invention I provide for delivering the protecting stream by
the party manipulating the hose, thus avoiding the necessity of a separate
hoseman to discharge the protecting stream on the one in the exposed position,
and putting the control of the protecting stream, in the hands of the one to
be protected, so its use and extent can be regulated by him as the occasion may
require.
The invention will be found useful in protecting firemen or others entering a
burning structure, or structures, or locations, wherein the smoke is so dense
that they could not otherwise enter in safety.
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―
1st. A hose nozzle having at one side a valvecasing, having
cating with the bore of the nozzle and its outer end arranged to discharge a
a port communi-
protecting stream upon the hoseman, and the valve operating in said casing sub-
stantially as set forth.
2nd. A nozzle having at one side a valvecasing provided with a port com-
municating with the bore of the nozzle such casing being provided at one end!
with a recess and the valve turning in the casing and controlling the port thereof,
and provided with a handle lying in the end recess of the casing substantially
as set forth..
3rd. A nozzle having a valvecasing provided with a port by which to deliver
a protecting stream such port being widened and a valve controlling such port
substantially as set forth.
4th. A nozzle provided at one side with a casing having a port arranged to
discharge rearwardly, and a valve controlling such port substantially as set forth.
Dated this 27th day of March 1899.
