Improvements in Hose Nozzles.
I JOSEPH ASKINS, of Edgwater Avenue, Ridgfield, in the County of Bergin, State
of New Jersey, United States of America, Inventor, 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, reference being had to
the accompanying drawings and to the letters and figures marked thereon, that is
to say :-
a
This Invention relates to that class of hose nozzles wherein a nozzle body is pro-
vided with opening and closing deflectors or jaws for discharging the liquid or water
in a flattened sheet.
The chief object of my Invention is to improve the prior constructions of such nozzles,
and to provide new and improved means for applying pressure upon opposite sides of
a cylindrical stream of liquid or water issuing from the cylindrical bore of a nozzle-body
in such manner that the stream is flattened and delivered in a wide sheet, or spray,
the dimension or size of which is controllable by the operator through the medium of
a simple and easily operated device.
To accomplish these objects my Invention consists in the combination of a nozzle-
body having an external collar, a rotary sleeve having a pair of opposite laterally
projecting cam-ribs and mounted on the nozzle-body at one side of the collar, a nut
or plate secured to the nozzle-body and confining the sleeve against longitudinal
movement while permitting it to rotate, and opening and closing deflector-jaws
pivoted to said plate and having tail pieces respectively acted upon by the cam ribs of
the rotary sleeve.
The invention also consists in certain other features of construction and combination
or arrangement of parts hereinafter described and claimed, reference being made to
the accompanying drawings, in which:
Fig. 1 is a side elevation of a hose nozzle constructed in accordance with my
Invention.
Fig. 2 is a longitudinal sectional view of the same.
Fig. 3 is a detail top plan of one of the deflector-jaws.
Fig. 4 is a plan view of the nut or plate to which the deflector-jaws are pivoted.
Fig 5 is an end elevation of the rotary sleeve having the laterally projecting
cam-ribs, and
Fig. 6 is a plan view of the spring for pressing the deflector-jaws apart, or to their
open position.
In order to enable those skilled in the art to make and use my Invention, I will now
describe the same in detail, referring to the drawings wherein the numeral 1 indicates
a nozzle-body which, as here shewn, is of tapering form and is provided at one end
with a screw socket 2 for engaging the hose or hose pipe to which the nozzle is to be
applied. The nozzle-body is constructed with a substantially cylindrical bore and is
provided at its outer end with an external screw threaded portion 3, at the rear of
which is formed a cylindrical bearing 4 and a lateral annular collar 5 which is pre-
ferably integral with the nozzle-body. The cylindrical bearing 4 serves to receive and
more or less accurately fit the interior of one end of a sleeve 6 which abuts the collar 5

page_text: and is formed integral or otherwise provided with two external cam-shaped or inclined
ribs 7 and 8. These ribs project laterally from the sleeve and gradually increase in
height from one end to the other, as will be readily understood by reference to Fig. 5.
The sleeve 6 is also formed integral or otherwise provided with a cylindrical
extension 9 which encircles the nozzle-body and is so constructed and arranged that
the hand of the operator can grasp the same and conveniently and quickly rotate the
sleeve upon the cylindrical bearing 4. I prefer to corrugate, roughen or serrate the
external surface of the cylindrical extension 9 to facilitate the rotation of the sleeve,
but I do not wish to be understood as confining myself to the corrugated, roughed, or
serrated surface.
The sleeve 6 is retained in position upon the cylindrical bearing 4 and is prevented
from longitudinal movement, through the medium of a nut or plate 10, best seen in
Fig. 4, which is screwed upon the threaded portion 3 at the outer end of the nozzle-
body, whereby the sleeve 6 is more or less loosely confined between the collar 5 and
the nut or plate. By this means the sleeve is free to rotate or turn upon the
nozzle-body, but is held in proper operative position thereupon and is prevented from
undue movement longitudinally of the nozzle-body.
The nut or plate 10 is approximately square and two of its sides are bevelled,
curved, or inclined as at 12, while its other two sides are each provided with two
pivot pins 13, preferably formed of metal screws fitting screw threaded sockets in the
nut or plate. These pivot pins constitute pivotal bearings for the two deflector-jaws 14
which are so mounted upon the pivot pins as to provide rearwardly projecting tail
pieces 15 which bear against the cam-shaped ribs 7 and 8 of the sleeve 6, in such
manner that by rotating the sleeve in one direction the tail pieces will be gradually
and uniformly moved outwardly for the purpose of closing the two deflector-jaws
towards each other. The deflector-jaws are constructed respectively with side flanges
so relatively arranged that the flanges on one jaw may move between the flanges on
the other jaw to permit of the outer ends of the jaws being brought into comparatively
close relation to each other, in order that they will discharge the liquid or water in
a flat sheet or stream.
The interior of the deflector-jaws are provided with shoulders 16, best seen in Fig 2,
which are located in proximity to the nut. or plate 10 in such manner that a circularly
shaped wire spring 17 can be seated between these shoulders and the nut or plate, so
that the spring is thereby secured and retained in position without the employment
of extraneous fastening devices or means. The spring is practically a split elastic
ring having its free extremities 18, Fig. 6, adapted to bear against the internal surfaces
of the deflector-jaws at points slightly in advance of the pivot pins 13, so that the
spring constantly tends to press the outer ends of the deflector-jaws away from each
other.
The side flanges of the deflector-jaws 14 are cut away, as at 19, to provide lateral
air inlet orifices by which air may enter into the jaws when they are closed together
and the sheet of water is being discharged in the form of a flat sheet or
stream.
The stream of liquid or water will, in the practicable use of the nozzle, issue from

jaws, if closed or nearly closed, exert pressure upon two opposite sides of the cylindrical
stream after it has left the nozzle-body and causes this stream to flatten out and spray
in a wide, flattened sheet which may be varied from ten to forty feet wide as desired
by the operator according to the dimensions of the parts.
The efficiency of my improved construction is due in a large measure to the fact
that the opening left after the deflector-jaws are closed is considerably greater in area,
say twenty-five per cent. greater, than the opening through which the water emerges
from the nozzle body, and, furthermore, the openings at the sides of the deflector-jaws
induce a current of air. By the means described the flattened column of water will
be freely discharged and delivered over a very large area.
Another desirable and important feature of my Invention resides in the fact that a
comparatively small movement of the sleeve 6 effects the opening or closing of the

page_text: two deflector-jaws. A quarter turn of the collar is sufficient to close the deflector-jaws
and this is very advantageous over prior constructions where a conical nut requires to
be moved a considerable distance in screw threaded engagement with the external
surface of the nozzle-body for the purpose of closing or opening the pivoted
deflector-jaws.
As before stated, the movement of the sleeve in one direction effects the closing
of the two deflector-jaws. The opening movements of the two jaws is permitted
by turning the sleeve in the opposite direction, so that the spring is permitted
to throw the two jaws apart. The pressure of the liquid or water against the internal
surface of the jaws of course tends to open the jaws, but the spring is desirable in that
it secures a uniform and steady motion of the jaws as they open.
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 I claim :
1. The combination of a nozzle-body having a collar, a rotary sleeve having a pair
of opposite laterally projecting cam-ribs and mounted on the nozzle body in juxta-
position to said collar, a plate secured to the nozzle-body and holding the sleeve
against lateral motion while permitting it to rotate, and opening and closing deflector-
ja ws pivoted to said plate and having tail pieces respectively acted upon by the
laterally projecting cam-ribs of the sleeve, substantially as described.
2. The combination of a nozzle-body, a rotary sleeve having a pair of opposite
laterally projecting cam-ribs, means for holding the sleeve against lateral motion while
