PROVISIONAL SPECIFICATION.
Improvements in Fittings for Gas and other similar Pipes
and Tubes.
I, JOHN DUNGEY of 86 New Cross Road, London in the County of Kent, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in fittings for gas and other similar pipes and
tubes has for its object to provide improved means for supporting hinged
or jointed pipes and consists essentially in strengthening the support on which the
pipes work, and in combining with the said support an automatic tap or cock, so
that when the hinged pipes are moved out of the way the gas is automatically
cut off.
pro-
In a fitting constructed according to this invention a two armed bracket is
vided with a base plate to enable it to be readily fixed in any desired position
and a conical plug is mounted in the said arms and secured by a nut on its
smaller end. A plug barrel works on the plug and is provided with a socket
in which the pipes are secured. It will thus be seen that the plug is supported
at both ends instead of only at one end as is usual. A passage leads from the
socket to a port in the centre of the plug barrel and works in conjunction with
a similar port in the plug. The port in the plug is in connection with a passage
either leading to a socket in the larger end of the plug or leading through the
plug to the bracket and centrally through the base plate. It will readily be
seen that when the barrel is turned in the plug to move the pipes out of the
way the gas will be shut off at the plug.

COMPLETE SPECIFICATION.
Improvements in Fittings for Gas and other similar Pipes
and Tubes.
I, JOHN DUNGEY, of 86 New Cross Road, London, in the County of Kent,
Gas Engineer, 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 for improvements in fittings for gas and other similar pipes and
tubes has for its object to provide improved means for supporting hinged or
jointed pipes and consists essentially in strengthening the support on which the
pipes work and in combining with the said support an automatic tap or cock, so
that when the hinged pipes are moved out of the way the gas is automatically
cut off.
In a fitting constructed according to this invention and illustrated in Figure 1
of the accompanying drawings a two armed bracket a is provided with a base
plate to enable it to be readily fixed in any desired position, and a conical plug c
is mounted in the said arms and secured by a nut d on its smaller end. A plug
barrel e works on the plug and is provided with a socket f in which the pipes are
secured. It will thus be seen that the plug is supported at both ends instead of
only one end as is usual. A passage g in the socket communicates, through the
passage in the plug, with a similar passage in the bracket a and centrally
DO17

page_text: through the base plate b. It will readily be seen that when the barrel is turned
on the plug to move the pipes out of the way the gas will be shut off at the plug.
Instead of the base plate a screwed socket similar to the socket may be
provided for securing the bracket a to a pipe, or the supply pipe may be connected
to a socket communicating with the passage i.
Figure 3 illustrates a modification of Figure 1 in which the plug e terminates in
a socket end'm to which the supply pipe is secured the passage h being in com-
munication with it instead of the bracket a.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:―
1. In a fitting for gas and other similar purposes securing the plug at both ends
to two projecting arms of the supporting bracket, substantially as described.
2. A fitting for gas and other similar purposes comprising a bracket a, a plug c
secured to the said bracket, a barrel e working on the said plug and having
channels 9 h, i, connecting the socket to the bracket a so as to form when in
one position a continuous channel but which when displaced from that position
shuts off the supply substantially as described.
3. The combination of the bracket a, plug c having a socket m, and barrel e
working on said plug, the sockets and m being connected by passages g h sub-
stantially as described and for the purpose specified.
4. The arrangement and construction of fittings for gas and other similar pipes
and tubes substantially as described with reference to the drawings.
