Improvements in Apparatus for the Speedy Application of Gas to
the Wing Lights, Ground Rows, and to the Stages of Theatres
and Public Halls Generally.
I, JOSEPH TOLLERTON, of 13 Merrion Place, Leeds, in the County of York, Gas
Engineer, do hereby declare the nature of this Invention to be as follows:-
The object of my invention is to provide a simple, easy and effective means of
turning on and off the gas of temporary lights used in connection with theatres,
public halls and the like, without using a wet dip as used heretofore.
I connect to the gas supply pipe a nipple and cock, connected to the plug of the
cock is the feed pipe or tube which passes through the centre of the joist to the under
side of the coverplate to which is a lid, the inside top of the feed pipe is chased or
screwed and has two recesses at the top opposite to each other, into which two wings
formed upon a collar of the stand pipe fit, the aforesaid wings are for turning on and
off the gas, there are corresponding recesses in the coverplate.
The end of the stand pipe is preferably taper, and is fixed by simply pushing it
into an indiarubber washer within the feed pipe, this washer is secured with a brass
or metal ring by a nut tapped in the thread of the upper part of the feed pipe or by
other means and forms a perfect joint, the inside of the washer being taper from the
centre to the outsides so that it always springs inwards.
By this arrangement the stand pipe cannot be taken out without turning off the
gas, and it has only to be pushed into position and turned one quarter turn to turn
on the gas and lock the stand pipe by means of the wings on the collar passing under
the coverplate.

upon the cock when the valve or passage is open.
Fig. 7, is a plan through the line A, B, (Fig. 1.) showing the position of the stop
upon the cock when the valve or passage is closed.
I connect to the gas supply pipo (a nipple and cock D, connected to the plug
of the said cock is the feed pipe or tube E which passes through the centre of
the joist to the underside of the coverplate F to which is a lid G, the inside top H
of the feed pipe E is chased or screwed, and has one or more recesses J at the top
oppo ite to each other, into which one or more corresponding wings K formed
upon a collar 1. of the stand pipe M fit. The aforesaid wings K are for turning
on and off the gas, there are also corresponding recesses or openings N in the
cover plate F.
The lower end of the stand pipe M is proferably taper, and is fixed by simply
pushing it into an india-rubber washer within the top of the feed pipe E.
Around the said washer is a brass or other metal ring P, the said washer O is
secure within the top El of the feed pipe E by means of a nut R tapped to
engage with the threads upon the inner circumference or surface of the top H of
the feed ipe E, or by other means, and when in the said position forms a perfect
and dry joint. The inside of the said washer O is taper from the centre to the outsides
so that it always springs inwards.
The connections to the stand pipe M may be either a flexible tube or a coupling or
union.

page_text: By this arrangement the stand pipe M cannot be taken out without turning
off the gas, and the said stand pipe M has only to be pushed into position and turned
one quarter turn to turn on the gas and lock the stand pipe by means of the wings K
upon the collar L passing under the cover plate F.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The dry joint substantially as shown and described.
2. The combination of the dry joint, stand pipe, feed pipe, supply pipe, and cock
and nipple substantially as and for the purposes shown and described.
3. The arrangement of apparatus as and for the purposes shown and described.
