Year: 1885

page_text: We FRANCIS HERBERT WENHAM of 238 Goldhawk Road Shepherds Bush in the
County of Middlesex Engineer and JOHN HOLMES SHELDRAKE of 12 Rathbone
Place Oxford Street in the said County Gas Engineer do hereby declare the nature
of said Invention for "IMPROVEMENTS IN TAPS OR STOP COCKS to be as follows:-
The principal object of our Invention is to provide a means of readily adjusting
the passage through the plug of a tap or cock in accordance with the requirements
at the place at which it is used to prevent' an excessive flow of gas water or other
fluid through the tap or cock.
"
With this object we pass a rod (preferably screwed) axially or longitudinally
through the plug of the tap or cock or otherwise in such manner that the inner end
of the rod can be caused to obstruct the passage through the plug of the tap or
cock more or less in accordance with requirements-Wen used as a gas tap a bye
pass may be made past the plug of the tap or cock and in the substance of the shell
or body of the tap or cock and capable of being closed opened and regulated by a
screw or otherwise-This bye pass allows a small constant supply of gas to pass
when it is wished to keep a small flame, burning.

Agent for the said Francis Herbert Wenham

We FRANCIS HERBERT WENHAM of 238 Goldhawk Road Shepherds Bush in the
County of Middlesex, Engineer, and JOHN HOLMES SHELDRAKE of 12 Rathbone
Place, Oxford Street, in the said County, 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 :-
The principal object of our Invention is to provide means for allowing a small
quantity of gas to pass through the body of a gas tap or cock when the main
supply is cut off and also to provide means for regulating this small quantity of gas
so passing and for cutting it off entirely when desired. It is designed to supersede
the ordinary external bye-pass hitherto used. The bye-pass according to this Inven-
tion is made past the plug of the tap or cock and in the substance of the shell or
body of the tap or cock and is capable of being closed opened and regulated by a
screw or otherwise. This bye pass allows a small and constant supply of gas to
pass when it is wished to keep a small flame burning.
The accompanying Drawing represents sections of means according to our Inven-
tion. A is the body or shell of the tap. B is the plug shewn with an adjustable
central screw B2 which can be used to regulate the passage through the plug but
this can be dispensed with and an ordinary plug be used. C is the bye-pass made
through the body or shell of the tap and C2 is a screw by which the amount of gas
passing can be regulated. The check or set nut c³ may be used to fix the screw c²
in its adjusted position.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
A tap or stop cock provided with a bye-pass extending its whole length through
the body or shell of the tap or cock as hereinbefore described.
