IMPROVEMENTS IN VALVES OR COCKS
Year: 1884

page_text: I, LEE DARNEAL CRAIG, of San Francisco, California, United States, Notary
Public, do hereby declare the nature of my Invention for IMPROVEMENTS IN
VALVES OR COCKS, and in what manner the same is to be performed, to be.
particularly described and ascertained in and by the following statement:-
The nature of my said Invention will be readily understood by reference to the
accompanying Drawing making a part of this Specification in which :-
Fig. 1 is a sectional elevation of my improved valve or cock, constructed for the
wash-stand.
Fig. 2 is an isometrical perspective view of the cone valve cylinder showing the
discharge spout broken off.
Fig. 3 is an isometrical perspective view of the outer case, and
Fig. 4 is an isometrical perspective view of the cone valve plug employed in the
construction shown in Fig. 1.
Fig. 5 is a longitudinal elevation of the same as employed in the construction of
the bath-tub faucet.
Fig. 6 is a sectional elevation of the same as employed in the construction of the
hose bib.
Fig. 7 is an isometrical perspective view of the valve plug, and
Fig. 8 the key belonging to the hose bib shown in Fig. 6.
In order to show the construction of the same, I shall refer to the Figures
separately.
In Fig. 1 A represents the case which is designed as a cover or cap to secure tho
whole in place. The lower end is furnished with a male screw B, by which it
couples with the hydrant or pipe connection by means of the female screw C in
which it operates. D represents the valve cone which serves as a valve while the
valve plug E serves as a valve seat. The spout F is screwed or otherwise attached
into the valve cone D; the valve plug E has the port G which is opened and closed
by operating the valve cone (as will be more fully explained). H. and H represent
the cross-head of the conical valve plug E which operates in any suitable guide
slots in the sides of the case A for the purpose of holding the valve plug E from
revolving by the friction of the cone valve D; the spring I, is designed to hold the
valve plug E to its seat in the valve cone D.

page_text: In Fig. 2 the valve cone D is designed to fit nicely in the case A, near the base
and top. The discharge spout. F works through a slot K, which allows it to
revolve, as will be shown.
Fig. 3 shows the outer case A which has the slot K for the discharge spout F to
operate through. The screw B is designed to operate in the female screw C, for
the purpose of attaching and holding the working parts together.
In Fig. 4 the valve plug E, shows the cross-head H, H, which operates in any
suitable guide slots in the case A and port G.
In Fig. 5, K represents the outer case which locks the whole faucet together and
serves as an outer valve. The seat and hydrant attachment are the same as that
shown in Fig. 1. It has the male screw L which operates in the female screw M.
The valve plug N rests upon the washer O, which in turn rests upon the spring P,
which holds the same in its seat in the outer case K. The key R has the collar S,
which operates in the recess T, and holds the square end. U, of the same in the
valve plug socket V. It is held down by the screw cap W. The handle X, is
attached by means of the screw Y. The spout Z is such as is generally used for
bath-tub faucets.
Fig. 6 shows the construction of a hose bib. The outer case A¹ serves as a valve
seat for the valve plug B'. The valve plug B¹ is operated by means of the key C¹
which has a square socket D', fitting to a square shank or tenon E¹, upon the outer
end of the valve plug B, The handle is set fast by the screw F'. The
discharge or hose spout G¹ is generally cast fast to the outer case.
Fig. 7 shows the hose bib valve plug B¹ with port J¹ and shank E¹ and screw
hole L¹,
Fig. 8 shows the key C¹ shown in Fig. 6. It is designed to show the key
socket D¹.
!
The following is the operation of my improved faucet. In Fig. 1, the same is
turned on or the spout. is opposite the valve port. To turn the same off, it is only
necessary to swing the spout F to either side when the valve plug, being held 'in'
position by the cross-head H, H, and the spout F, turned off from the port G, the
discharge is entirely closed..
F
1.1.
It will be seen that the greater the pressure against the under and inner, side of
the valve plug E, the more tightly it fits to its seat in the valve cone D. The
spring I is only necessary to keep the valve closed by keeping the plug E' in place
when nearly all the pressure of water is removed.
i
In Figure 5, the faucet is attached to the hydrant of the bath-tub in the usual
way. The valve plug N, is held in its seat the same as the valve plug E in Fig. 1,
except that the washer O intervenes to form a broad bearing for the spring P
The valve plug N has the socket V in which the shank U fits. The port A of
the valve plug N is shown in conjunction with the spout Z and the faucet is open
for discharge.
It will be readily seen that the water will be turned off by simply revolving the
handle X in either direction. When the cap W is unscrewed, the key R may be
taken out thus preventing the liability of having the water turned on when not,
required.
In Fig. 6, the construction and operation of the hose bib is shown to be quite
similar to that shown in Fig. 5. The valve operates in the seat in the same way,
but it has no spring to hold it up. It has but little play and is easily held tightly
in its seat by the pressure of the water. It is turned on and off by the handlo H.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to bo performed, I declare that what
I claim is
1
First. The conical valve plug E with cross-head H, H, to prevent lateral
movement, in combination with the cone valve D having the slot K for the
discharge spout F to operate through and the inale screw B to operate in connection
with the female screw C, with or without the spring I constructed and operated
substantially as and for the purposes set forth.

page_text: Second. The valve plug N with socket V, to receive the key shank U, the
port A to connect with the spout Z, the washer and spring P, in combination
with the case K having the cap W, the key R, and washer J, with collar S,
constructed and operated substantially as and for the purposes set forth.
Third. The valve plug B¹ with square shank E¹ to connect with the key C¹
having the square socket D' in combination with the case A' having the discharge
or hose spout G constructed and operated substantially as and for the purposes set
forth.
