COMPRESSION STOP AND DRAIN VALVE
Joseph R. Guildford, Regina, Saskatchewan,

Application November 16, 1936, Serial No. 111,019
(Cl. 251—20)
11 Claims.
My invention relates to improvements in a
compression stop and drain valve, and has for its
primary object to provide, in a manner as herein
after set forth, a stop and drain valve embody
5 ing a novel construction, combination and ar
rangement of parts through the medium of
which, ?uids beyond the valve may be drained
from piping, equipment, plumbing systems and
10
the like.
On the market at the present time there are
compression stop and drain valves in which the
drain or waste feature is incorporated in the side
or bottom of the valve casing requiring a special
ly designed valve casing. In others the drain
feature is incorporated in the side of the bonnet
of the valve.
In my invention the drain feature is incorpo
place near the vertical axis of the valve stem by
a screw l5. A threaded bore is provided at it
for the reception of the screw I5.
A web or partition i‘! carried across the casing
E of the valve 5 is provided with an opening It!
for the passage of ?uids from the inlet E9 to
the outlet 2i] when the valve is open. Threads 2!
are provided for attaching the valve to a pip
line.
‘i
The lower side of the web ll around the open
ing 18 is provided with an annular raised seat 22
which is smoothly faced for the abutment of
the compressible annular disk M when the valve
is closed.
To prevent the handle l i from rotating on the 15
valve stem ii), a portion of the valve stem It is
squared or milled at 25. A lock nut 25 is thread
rated in the stem of the valve, and a most im
edly mounted on the valve stem to fasten‘ the
portant object of the invention is that it will on
able one to convert an ordinary compression stop
valve into a compression stop and drain valve by
handle in place. A cap 21 is threadedly mounted
on the lower end 39 of the valve stem iii and
merely changing the valve stem assembly.
'
Another object of the invention is to provide
a compression stop and drain valve, simple in
construction, reliable in use, compact and easily
cleaned.
All of the foregoing and still further objects
and advantages of the invention will become ap
parent from a study of the following speci?ca
30 tion, taken in conjunction with the accompany
ing drawing wherein like characters of reference
designate corresponding parts throughout the
several views, in which:—
Figure 1 is a view in vertical longitudinal sec
tion through the compression stop and drain
valve through one embodiment.
Figure 2 is a bottom plan view of the compres
sion stop and drain valve.
Figure 3 shows a valve stem assembly partly in
vertical section incorporating a similar but
slightly changed valved drain feature.
Figure 4 shows a section of the valve stem as
semblies on lines 4-4 looking upward.
Referring to the drawing:—
The numeral 5 designates the compression stop
and drain valve which comprises the casing 6,
the cap nut ‘I threadedly attached to the casing
6 at 23, a brass washer 8, a fabricated cone pack
ing 9 through which operates the rotatable stem
I [I carrying the handle II. The valve stem is
threaded as indicated at I2 for co-operation with
a threaded bore 24 in the casing 6.
The upper end of the valve stem Ill is provided
with an annular disk holder 13 in which a com
55 pressible annular disk I4 is retained and held in
Us
provided with a compressible washer 28.
A pas- “
sage 29 is provided lengthwise through the valve
stem Ii! permitting communication between the
outlet 28 and the atmosphere when the cap 2?
and washer 28 is removed from the lower end 30 9,)
of the valve stem ID.
‘
“
A swivel SE is provided and held on to the cap
21 by means of a metal washer 32 riveted or
otherwise fastened to the cap 2"! at 33. A chain
34 is provided for attachment of the swivel 3| 30
to the handle H thereby preventing the mis
placement or loss of the cap 27, when the cap 2'!
is detached from the lower end 38 of the valve
stem it}.
‘
While the valve is in operation the cap 21 is
screwed tightly onto the end 39 of the valve stem
ID compressing the washer 28 to make a water
tight joint. The valve is opened by rotating the
valve stem [6 drawing the compressible annular
disk M away from the raised seat 22 permitting 40
?uid to pass through the opening l8 into and be
yond the outlet 20. If it is desired to drain the
?uid from the outlet 20, the valve is closed and
the cap 7.‘! removed from the valve stem Hi. The
?uid to be drained will then pass through the 45
passage 29 and be Wasted to the atmosphere.
It will be obvious that if at any time foreign
matter collects in the outlet 2i’! or passage 29 it
may be quickly and easily cleaned by pushing a
wire through the passage 29.
.
In Figure 3, closure means for the passage 29
consists of a screw 35 which is movably disposed
within the valve stem ID. The lower end of the
screw 35 is provided with an enlargement in the
form of an annular milled flange 36. ‘
2,116,626
The upper end of the screw 35 is provided with
a conical point 31 for closely co-acting with the
conical shaped portion 38 of the passage 29. The
lower portion of the passage 29 for draining fluid
Ct
from the outlet 20 is diverted through the side
of the valve stem at 39.
When the passage 29 in Figure 3 is required
for drainage the screw 35 is screwed outwardly
from the valve stem I0 permitting ?uid to pass
10 through the conical portion 38 and through the
diverted passage at 39 into the atmosphere. If
the passage 29 should require cleaning of foreign
matter, the screw 35 may be removed entirely and
replaced when the passage 29 is clear.
Though I have shown and described herein a
preferred embodiment of the invention, it is to be
understood that I do not desire to limit the ap
plication of the invention thereto and any change
or changes may be made in material, structure
and arrangement of parts within the spirit of
the invention and the scope of the subjoined
