Improvements in Valves.
I, ORLANDO FERDINAND CONIHE, clerk, of Charlestown, in the County of Suffolk,
and State of Massachusetts, one of the United States of America, 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:
My invention relates to improvements in locking valves for gas or other pipos.
My invention consists in certain novel features of construction and combinations
of parts hereinafter fully described and claimed.
In the accompanying drawings:
Figure is a side elevation of my device,
Figure 2 is a longitudinal section thereof with the valve closed,
Figure 3 is a similar view with the valve open,
Figure 4 is a top plan view of the washer gate, and
Figure 5 is a plan view of the bottom of the body portion of my valve.
In the accompanying drawings, the numeral 1 indicates the body of the valve
which is provided with passages 2 and 3 having angle portions 4 and 5. A
passage 6 extends through the centre of the body portion. A valve stem 7 is held
to rotate within this passage and is provided with a pin 8 therethrough. Recesses 9
are made at predetermined points in the body of the valve and are adapted to
receive the pin 8 when the stem is turned to a certain definite position. A cap 10
is attached to the upper part of the body portion preferably by a screw joint, as
shown. Within this cap is a spring 11 normally holding the pin 8
in contact with the body of the valve. The lower portion of the valve is provided
with a valve seat 12, and a recess extending approximately one quarter way round
the valve seat,
is shown at 13. Upon this valve seat is fitted a washer 14 provided
with a passage 15 having a contracted end, as shown. Passages 16 extend from
this passage around the valve and meet in an opening 17 which is adapted to com-
municate with the egress pipe 3. A lug 18 is held within the recess 13 and regu-
lates the extent of motion of the washer gate. This washer gate is further provided
with a recess 19 in which is adapted to fit. a lug 20 upon the stem 7 when said stem
is forced in against the action of the spring 11. A cap 21 is attached to the lower
portion of the body of the valve and serves to hold the washer gate în its proper
position.
In operation the gas or other fluid enters the valve by the pipe 2, passes down-
ward when the valve is opened into the passage 15, thence around the stem by
means of the passages 16 into the opening 17 and from there into the egress
passage 3.
It will be observed from the drawings that owing to the peculiarly con-
tracted shape of the passage 15, the admission of gas or other fluid can be controlled
with extreme nicety. When it is desired to open the valve, the stem 7 is forced in
against the action of the spring, thus raising the pin 8 out of the slots and forcing
the projection 20 into the recess 19. By turning the handle of the stem,
the washer gate will now be revolved and as much as may be necessary of the
passages 15 caused to pass below the angle portion 4 of the passage 2.
The

page_text: spring 11, by holding the pin 8 upon the upper portion of the body of the valve,
will prevent the same from being turned without a considerable degree of force
is exercised, and when the valve is shut off prevent it from being accidently opened
This valve, by reason of the small opening that is at first afforded, is especially
adapted for use in pipes where the pressure is high and it is desired to gradually
equalize the pressure on both sides of the valve.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is,
1. In a valve, the combination of a body portion, a stem extending therethrough,
a washer gate held upon said stem and adapted to be rotated by the movement of
said stem, and a pawl normally locking said valve when closed, substantially as
described.
2. In a valve, a body portion having passages extending therethrough, a stem,
a washer gate carried by said stem and provided with a passage having a contracted
end portion, passages extending around the opening through which the stem passes,
and a recess communicating with said passages, and a cap extending from said
washer gate, substantially as described.
3. In a valve, a body portion having a central passage adapted to receive a valve
stem, extended end portions provided with valve openings, a stem held
to rotate within said central openings, a washer gate having passages
therein adapted to be rotated by said stem, a cap held upon the body
portion of said valve and adapted to retain the washer gate in position, a cap
extending over the upper portion of said stem having a recess therein, a spring
held within said recess normally urging said stem outward and a locking device
adapted to hold said valve in closed position, substantially as described.
4. In a valve, a washer gate having a central opening adapted to receive a valve
stem and provided with an entrance passage having a contracted end, passages
extending from said entrance passage around each side of the central opening, and
an egress passage with which said side passage communicates, substantially as
described.
