Improvements in and relating to Discharge Nozzles for Hose Pipe
and Means for Regulating the Water Supply thereto.
I, WILLIAM JACOB RICKARD, of No. 439 Haines Street, Philadelphia, Pennsyl-
vania, United States of America, Foreman, 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 relates to an improved construction of electrical indicator for
valves and discharge nozzles, which are adapted to be attached to a suitable
portion of a conduit, and to have an overflow pipe connected therewith, provision
being made for announcing at any given point the fact that the flow of water
through the conduit has been stopped, and that it is desired to shut off the source
of supply therefor.
It further consists of novel details of construction, all as will be hereinafter set
forth.

Referring to the drawings,
A Figure 2 designates the preferred form of valve employed, the same consisting
of the barrel casing B having its lower end screw threaded as at C Figure 1, and
provided with an inlet opening D.
E designates a seat located adjacent the opening D, upon which the valve F
is adapted to seat, said valve being attached to the head G, which is provided with
a socket J in which is seated the end of the spring K, the other end of the latter
fitting in the socket L of the head M.
N designates a seat or depression in the upper portion of said head M, in which
the end R of the threaded stem Q is adapted to rest, said stem passing through

page_text: and engaging a threaded opening in the cap P, which is attached to the shell or
barrel B of the valve.
S designates a boss or discharge outlet from the barrel B to which the overflow
pipe T Figure 2 is attached.
U and designate wires or other conductors which lead from a suitable
indicating device which may be a gong or electric bell W which is located
in an electric circuit said wires having their ends attached respectively to the
terminals X and Z, the same being located within the passage in the boss S, and
being suitably insulated.
Y designates a spring or circuit breaker which is mounted on the terminal X,
and is adapted to contact with the terminal Z when force is applied thereto, such
as may be caused by the flow of water to the overflow T, it being of course evident
that any other suitable circuit breaking device may be employed.
A¹ designates a water main' which has a branch leading therefrom to the valve C',
the latter having the pipe or conduit B attached thereto which enters the tee D¹,
the latter having a threaded opening located therein with which the threaded
portion C of the valve A is adapted to engage, said valve being thus normally
removed out of the direct flow of the water.
F designates a pipe or conduit connected with the tee D¹ and terminating in a
hose, which may be of any desired length and provided with a discharge nozzle G¹
Figure 3 attached to the hose by means of the coupling H¹ Figure 2, which latter
is provided with screw threads J on the interior, adapted to engage with screw-
threads on the ring K¹ Figure 3, the same having attached thereto by means of
pins or bolts L' the gate valves M1, N1, it being noted that the ring Ki Figures 3
and 13 and its connected parts are not put into position until the nozzle G¹ has
been passed through the opening in the coupling H', the latter having a flange Q¹
which engages with the end of said coupling. The aforesaid coupling G¹ is
provided with a beveled flange P1 adapted to engage with lugs on the gate
valves M¹, N¹. In the face of the flange Q are grooves or slots R¹
Figure 16 and in one end of each of the valves M¹, N¹ is a socket S¹
Figures 14 and 15 which is adapted to receive a ball T¹, said ball being partly in
the socket S¹, and partly in the grooves R¹.
UFigure 3 designates a sleeve which is screwed around the nozzle G¹ and is
provided with a groove V₁ on its inner face, which is opposite to a corresponding
groove Win the outer wall of the coupling H¹. In the said grooves U¹ and Vi
are springs A Figure 8 which have one end secured to the said sleeve U¹, and the
other end to the wall of the coupling H¹.
B2 designates openings or slots Figures 4 and 7 in any suitable point in the
Coupling H¹, which are adapted to receive a bolt or bar C2 pivoted to the sleeve U¹,
so that the same will hold the parts stationary when desired Figures 9 and 10.
At the outer end of the nozzle G¹ is a collar D2 Figures 3, 5 and 6, which is
provided with ways or slots E2 and notches F2. Mounted in said ways Ea are the
blocks G2 to which are pivoted the arms H2 which are actuated by the springs J2
which are adapted to hold the same in normal positions. Attached to said arms H²
are the plates K2 which are adapted to move forward and backwards and are
kept in place by the guide ring L³ Figure 3.
M² designates a spring which is around said collar D³ and has one end secured
thereto and bears against the blocks G2, and is adapted to hold the parts in normal
position.
Na designates a spring which is suitably secured at any desired point, and is
provided with a lug P which is adapted to enter said notches F³, said spring N
passing around the nozzle G2 and being provided with a headed pin Q³, as will be
further explained.
The casing R2 is placed around the arms and connections H2 and protects the
same.
The operation is as follows:
:-
In case of fire or other emergency, when it is desired to discharge water through

page_text: the nozzle G the bar C which is in one of the openings B2 (the valves being
closed as seen in Figure 11) is turned and is placed in the other notch or opening B2,
and the sleeve U is thus turned and carries with it the nozzle G¹ and also the
flange Q, which has the grooves R¹ in its face. The slots carry the balls T
which move therein, and as the same are in a socket in the gate valves M', N¹,
said gates will also be carried thereby, and the gate valves will be opened. The
positions that the balls assume in said grooves R₁ are best seen in Figures 14
and 15, thus a free and uninterrupted passage of water takes place through the
pipes F and the nozzle G¹, the valve A being situated as seen in Figure 1.
When it is desired to turn off the discharge of water and at the same time notify
the attendant in charge of the pump or forcing apparatus that the same should be
stopped, it is only necessary for the valve gates to be closed, which can be done by
reversing the operation just described, whereby the water in the conduit " is
forced up through the opening D into the valve A and discharges the same through
the outlet S into the overflow T. This discharge of water which forcibly takes
place will cause a contact to be made between the spring contact Y and the
terminals Z, completing the electric circuit and sounding the alarm W, which
latter it will be understood is to be located near the pump mechanism, thereby
notifying the attendant to at once stop the operation of the same, since it is no
longer needed.
It will of course be undestood that the alarm W employed may be set at any
point as may be desired, the engine house, office or residence.
The spring K and the spring contact Y can of course be adjusted according to
requirements and the pressure of the valve F upon its seat can also be varied by
moving the stem Q.
If for any reason it is desired to spray the water at the nozzle G¹ by pressing
the headed pin Q in the direction indicated by the arrow Figure 4, the lug P³
on the spring Na will be removed from the notch F2 which it occupies and as the
said spring which holds the blocks G2 has been released the said blocks G2 and
arms He may be moved outwardly, compressing the spring M2 until the plates K³
assume the position seen in dotted lines Figure 3, the said guide ring L³ causing
the said plates to assume this position.
The plates K2 are now in the path of water which will be sprayed as desired.
The extent of the forward moving of the said plates can be varied or adjusted by
allowing the lug P2 to enter any one of the notches F2 in the collar D². By releasing
the lug on the spring N the spring M2 will return the parts to their normal
position. This will be also the case when, if the gates have been opened, the
bar is removed from the notches 132, when the springs A2 will return the parts
to their normal positions, thus closing the gate valve.
It will of course be evident that various changes may be made by those skilled
in the art, which will come within the scope of my invention, and I do not
therefore desire to be restricted in every instance to the device herein shown and
described.

invention and in what manner the same is to be performed I declare that what
