Improvements in Gas or Vapor Cocks.
I, ORLANDO FERDINAND CONIIE, of No. 47 Main Street, Charlestown, in the
County of Suffolk and State of Massachusetts, one of the United States of America,
Clerk, do hereby declare the nature of this said 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 certain new and useful improvements in gas or vapor
cocks, to regulate the flow of gas or vapor from the gas supply pipe to the burner,
the object being to provide an improved construction which cannot be accidentally
turned on to permit the passage of gas therethrough, and to dispense with the em-
ployment of screws and other small pieces connected with the working parts
thereof so that any possibility of loosening and dropping out of parts is entirely
obviated.
To this end my invention consists in certain novel constructions, combinations
and arrangements of parts in a gas cock, as will be hereinafter more fully described
and specifically set forth in the appended claims.
In the accompanying drawing,
Figure 1 is a side view showing a portion of a gas supply pipe, a burner bracket
and my improved gas controlling cock connected therewith.
Figure 2 is a central transverse section of the cock.
Figure 3 is a central longitudinal section thereof.
Figure 4 is a detail perspective view of the controlling cone or plug.
Figure 5 is a bottom plan view of the same.
Figure 6 is a detail view of the key and its detached stem.
Figure 7 is a plan view of the bottom washer.
Figure 8 is a section on line 8-8 of Figure 2, looking up.
Figure 9 is a plan view of the bottom cap.
Like numerals designate like parts throughout the several views.
The cock case is constructed of three parts, a central body portion 1, a bottom
cap 2, and a top cap 3. The said 'body portion 1 is provided with two tubular
extremities 4, 5 opening therefrom, the former having a screw collar 6 adapted to
engage with the end of the gas supply pipe 7, and the latter being provided with
a boss 8, provided with an opening through which the inner end of the gas
bracket 9 fits and is secured by a screw 10 engaged therewith. This construction
of the body permits the gas or vapour coming through the said supply pipe to pass
to the gas burner mounted on the bracket. The said body portion 1 of the case
may be of any approved exterior shape, and in the present instance is provided
with a threaded flange 11 with which the bottom flange of the top cap 3 engages.
This top cap 3 is provided with a central chamber 121 terminating in a recess,
which, together with a recess in the top part of the body portion 1, when the two
are connected forms a space 12 into which a washer 13 fits. The body portion 1
has a cone-shaped or tapering passage therethrough which is in communication
with a recess 14 at the bottom of said body portion and this portion is provided

page_text: adjacent to said recess with a flange 15 which is threaded to engage the flange
portion 16 of the bottom cap 2. This bottom cap is provided with a central socket
and passage 17, the purpose of which will be presently described.
A cone-shaped valve plug 18 fits within the body portion 1 and is provided with
a central chamber 19 terminating at the lower end thereof in a contracted
passage 20 having a lateral passage 21 opening at the exterior side of the conical
plug. The bottom of this cone valve is provided with a central slot 22 opening
at the outer edge thereof, and the wall of the plug at the ends of the slot constitute
stop shoulders 23. This plug is provided with a horizontal outlet passage 24
which when in line with the two tubular extremities 4, 5 of the central body
portion 1 permits the gas or vapour to flow from the gas supply pipe to the
burner.
The bottom cap 2 is provided with a passage 25 in communication with its
central socket 17, and a key 26 has a stem 27 projecting through said passage and
sockets and through the contracted passage and socket in the conical plug and top
washer to the chamber of the top cap 3, which the upper end of the said stem
occupies.
A washer 28 occupies the space or recess between the central body portion 1 and
bottom cap 2, and this washer is provided with a central keyhole-shaped slot 29
and a niche 30 in the rim thereof which communicates with a stop projection pr
pin 31 on the interior of the body or shell 1, said projection preventing the washer
from turning. A second stop projection or pin 31¹ extends through an opening 32
in the said washer and occupies the segmental slot 22 of the conical plug 18, and
serves to limit the extent of rotary movement of said plug by contact with the said
shoulders 23, and also to prevent the washer from turning.
The lower end of the stem is provided with a web or bit 34, which normally,
when the conical plug is closed to prevent the passage of gas to the burner,
occupies the recess 17 of the base cap, but it is adapted to be passed up through
the keyhole-shaped slot 29 in the washer 28 to engage the groove or lateral
passage 21 in the bottom of the conical plug 18, whereby upon turning the key 26
secured to the stem 27 the said plug may be turned so as to bring its horizontal
opening into and out of coincidence with the tubular extremities 4, 5 of the top
portion 1 in order to permit or shut off the flow of gas from the gas supply pipe,
the extent of movement of the plug either way being limited by the pin 31 and
shoulders 23, as hereinbefore mentioned.
The upper end of the key stem 27 is provided with a cross piu 35 extending
therethrough, and a spiral spring 36 in the chamber of the top cap 3 has position
on the stem and bears upon the said pin and against the top of said cap. A spiral
spring 38 also surrounds the central portion of the stem in the central socket 19
of the conical plug 18 and the upper end thereof bears against the top washer 13,
while the lower end thereof bears against packing material 39 surrounding the
said stem at the base of the said socket 19. These springs 36 and 38 normally
tend to press the key 26 and its stem 27 downwardly so as to force the web or bit 34
thereon out of engagement with the plug groove 21 and down into the base cap
recess 17, which position it normally occupies when the plug is turned to shut off
the flow of gas. The packing material 39 surrounding the stem prevents the gas
from following the stem and leaking to the exterior at the bottom of the case.
After the stem has been forced down by the tension springs as described, it may
be turned either way as desired, but the plug valve will not be opened and no
vapor or gas can pass through the cock.
It will be seen that in my construction of gas cock no screws or other small parts
which are liable to be detached and fall out are employed.
By my construction it will also be seen that the key may be turned when the
plug is in position to cut off the gas, without affecting the position of said plug,
and hence all liability of accidentally turning on the gas is entirely obviated. 5
The plug cannot be turned until the key stem is forced up to bring its bit in
connection with the plug as before described.
