PROVISIONAL SPECIFICATION.
Improvements in Hose Nozzles.
ROBERT WISE, residing at No. 153 Alexander Avenue, in the City aud State
of New York, United States of America, Machinist, do hereby declare the nature
of this invention to be as follows:-
Nozzles for hose have heretofore been made either to throw a straight jet or to
project a spray by the water passing through numerous holes, and in some instances
the water has been projected through an annular opening so as to form a bell-
shaped spray, but difficulty has been experienced in so arranging the parts,
especially in hose nozzles made use of by firemen, that the single jet could be
projected or the spray turned on for protecting the fireman from a sheet of flame or
smoke, by driving the same in front of them.
The object of the present invention is to combine a jet nozzle and an annular
spray in such a manner that the party using the same can turn on either the jet or
the spray or both at will, and shut off either one without affecting the other.
With this object in view, the hose nozzle is provided with a stop cock or valve
for closing the single delivery jet, and around the jet tube is a flange, and there is
a bell-shaped forward end around the flange and a screw, by which to adjust the
opening between the end of the bell-shaped nozzle and the flange, so as to vary the
annular spray or jet that diverges as it issues from the nozzle, and this annular jet
can be of more or less volume, or shut off entirely, and by providing a by-pass
around the barrel of the cock or valve, the water can reach the annular spray at
any time, and the cock or valve regulates the discharge of water from the jet
nozzle.
In one of the forms made use of the flange around the jet nozzle is stationary
and the bell is adjustable towards and from the same, and in the other form of this
nozzle the bell is stationary and the annular flange is adjustable upon the jet
nozzle.

Improvements in Hose Nozzles.
1, ROBERT WISE, residing at No. 153 Alexander Avenue, in the City and
State of New York, United States of America, Machinist, 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:-
Nozzles for lose have heretofore been made either to throw a straight jet or to
project a spray by the water passing through numerous holes, and in some instances
the water has been projected through an annular opening so as to form a bell-
shaped spray, but difficulty has been experienced in so arranging the parts,
especially in hose nozzles made use of by firemen, that the single jet could be

page_text: projected or the spray turned on for protecting the fireman from a sheet of flame
or smoke, by driving the same in front of them.
The object of the present invention is to combine a jet nozzle and an annular
spray in such a manner that the party using the same can turn on either the jet or
the spray, or both, at will, and shut off either one without affecting the other."
With this object in view, the hose nozzle is provided with a stop cock or valve
for closing the single delivery jet, and around the jet tube is a flange, and there is
a bell-shaped forward end around the flange and a screw by which to adjust the
opening between the end of the bell-shaped nozzle and the flange so as to vary the
annular spray or jet that diverges as it issues from the nozzle, and this annular jet
can be of more or less volume, or shut off entirely, and by providing a by-pass
around the barrel of the cock or valve, the water can reach the annular spray at
any time, and the cock or valve regulates the discharge of water from the jet
nozzle.
In one of the forms made use of, the flange around the jet nozzle is stationary
and the bell is adjustable towards and from the same, and in the other form of this
nozzle the bell is stationary and the annular flange is adjustable upon the jet nozzle.
In the drawing,
Fig. 1 is a longitudinal section of the improved hose nozzle. Fig. 2 is an end
iew of the same.
Fig. 3 is a cross section at the line 3, 3, of Fig. 1, and
Fig. 4 is a longitudinal section showing the annular flange as adjustable.
The body A is of any desired size or shape, and at B the plug of the cock is
represented. This may be of any desired character, and either in the form of a
barrel 8 and plug B, or any suitable valve may be provided.
The central jet tube C extends out from the cock or valve B and the discharge
of water through the central jet tube is regulated by such plug or cock, and around
the jet tube C is an annular flange D which in Fig. 1 is represented as permanently
fastened in position, and the bell E surrounds the central jet C and is screwed upon
the forward end of the body of the nozzle, and by adjusting the bell E, the annular
water-way 15 between the flange D and the forward end of the bell E can be
varied so as to allow more or less water to be projected in the form of a spray or
shield for the fireman, and which spray or shield will be more or less powerful
according to the width of the opening 15.
The nut 11 with a flexible washer between the same and the rear end of the
bell E prevents the leakage of water at the screw 7 upon the forward end of the
body A of the nozzle.
If desired, a removable reducer or jet G may be provided for the end of the jet
tube C to vary the size of the jet.
It is advantageous to provide a ring of rubber 16 around the bell E to lessen
the risk of the same becoming bent by concussion.
The water-way 5 passes around the barrel 8 of the cock so as to form a by-pass
that supplies the water to the passage 6 that extends to the interior of the bell E
and when the bell E is screwed tightly against the annular flange D, the discharge
of water at 15 is prevented.
The device represented in Fig. 4 corresponds to that shown in the other figures,
with the exception that the screw thread is upon the outside of the hell E, and
there are arms 9 extending from a ring F that surrounds the screw thread to the
flange D' that surrounds the jet tube C so that this annular flange can be moved
towards and from the end of the bell for varying the width of the annular water-
way or closing the same entirely; and in this form it is advantageous to provide a
stuffing box with an elastic packing and a tightening screw 10 to prevent leakage
of water between the jet tube C and the annular flange D'.
In either of the forms represented, the fireman or other person is able to easily
adjust the annular spray or stream of water from behind the same so that the
regulation of the water can be easily effected while either or both streams may be
issuing from the nozzle.

page_text: 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. The combination in a hose pipe nozzle with the central jet tube, of an
annular flange surrounding such jet tube, a bell upon the forward end of the body
of the nozzle and means for adjusting the opening between the edge of the bell and
the annular flange from behind the spray or annular jet issuing between the end of
the bell and the flange, substantially as set forth.
Second. The annular flange D upon the jet tube in combination with the
bell E screwed upon the forward end of the body of the nozzle for adjusting the
aunular water-way by screwing the bell forward or backward, substantially as set
forth.
Third. The combination in a hose nozzle, of a central jet and a cock or valve to
regulate the discharge of water through the same, a water-way passing by the cock
or valve, an annular flange around the jet tube, a bell into which the by-pass opens,
and means for adjusting the width of the annular water-way between the end of the
bell and the annular flange, substantially as set forth.
Dated this 28th day of September 1896.
