do hereby declare the nature of this invention to be as follows:-
:-
The cock may be made of any kind of metal or material as desired and of any form
or shape as required but commonly it will be made of ordinary brass and in shape and
construction like unto those gas cocks common to gas fittings but with such additions
and alterations as herein specified. The body of the cock having a hole through it
for the gas to pass through is drilled or bored & tapped to receive the pipes between
the point of ignition and the ordinary or common stop cock connected to the gas
bracket. The body of the cock above referred to has also a hole bored & reamered
preferably at right angles to its axis, to receive the plug which is turned &
ground into its seating and secured in the usual way or in any other convenient
manner. The plug has stops fitted to it which prevents the supply of gas from being
completely cut off "leaving such an amount of opening through the cock, that the gas
being once ignited cannot be extinguished only by turning off the supply of gas at
the common cock previously referred to.
"
The novelty I claim for my invention is this, that should the person or persons
using the light from the pipe fitted with it have occasion to leave their place the light
may be turned down from full to a small glimmer instantly and without any care or
skill whatever, and when required again can be turned as readily to full without fear
of the light being extinguished. The supply of gas can also be regulated to any
degree between a glimmer and a full light.

Improvements in Gas-cocks.
I, THOMAS FOSTER of 221 Ridgway Street Butler Street, Manchester 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 improvements which are the subject of this invention, relate to metal gas-cocks
or taps, and consist in the formation or construction of a cock or tap that may be
used independently or in combination with the ordinary gas-cock, for the purpose of
enabling a small jet or flame, consisting of a previously arranged fixed quantity of
gas, to be left burning in workshops or other places during meals, or at times when
the full amount of gas is not required.
The object of this invention is to prevent waste of gas by a large flame being left
uselessly burning, and also avoiding the risk of escape through carelessness by
turning gas jet out and afterwards turning tap on without gas being ignited.
In order more clearly to describe this my invention I have annexed hereunto a
sheet of drawings: in the several views illustrated therein similar letters refer to
similar parts. The general form or outline of gas cock therein shown may be varied
to suit requirements.
Fig. 1. represents side view. Fig. 2. is plan and Fig. 3. sectional plan of gas cock
or tap. In these views the tap a is represented as open the stud or stop c which is
attached to plug & resting against the projection e formed on body of cock. The
stop is attached to plug in a position which will allow a previously arranged
diminished amount of gas to pass through the hole from the passage g to the
passage gas is represented in Fig. 4. plan, and Fig. 5. sectional plan, of gas cock :
In these views the stop e' is in contact with the projection el on cock, thus preventing
the tap being completely closed, and by these means the ignition of a small flame
or jet of gas of fixed dimensions is constantly retained without reliance upon the
user.
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
In a gas cock or tap which is used to regulate the admission or passage of gas
from the main to the burner, the formation of said gas cock either in the manner
herein above described or of other similar construction, in order that the supply of
gas to burner may be diminished to a very small amount, without the possibility of
the jet or flame being totally extinguished by carelessness or inattention.
