Improvements in Gas Fires.
I, WILLIAM MCCAIG of 665 Cathcart Road, Govanhill, Glasgow, in the
County of Lanark, North Britain, Tailor, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in gas fires, and has for its object simplicity
and cheapness in construction, and a better glow of heat with less consumption
of gas.
The invention consists of a series of curved pipes, according to the size of the
fire place, connected together by means of a plate. On the top or flat part of
each of these curved pipes there is an opening in which there is placed a small
tube or pipe tapped at each end. This tube is provided with small pin holes
where it rests in the curved pipes for the purpose to be hereinafter described. In
the centre of this tube there is also a coupling for connecting the pipe supplying
the gas from the meter. I should here explain that I prefer the gas supply pipe to
pass through the back brick of the fire place, so that nothing offensive to the eye
will be seen; or it may pass up through the bottom of the fire place.
In carrying my invention into practice I place this arrangement of pipes in the
fire place so that the two ends of each of the series of curved pipes, which constitute
the burners, will be in a vertical position. I then couple on the gas supply.
Between the ends of the series of curved pipes I have a brick, and resting on the
top I have another brick lying at an angle so that the heat may be thrown back;
or in place of two separate bricks I may have one brick so moulded as to serve the
same purpose. I then fill up the rest of the fire place with asbestos or other
analogous material. When the gas is turned on it passes from the supply pipe
into the tube and escapes through the pin-holes into the curved pipes and it
along with the air which enters the curved pipes at the openings passes out at the
ends of the curved tubes where it is lit, and a regular glow of heat is given off.
It is to be understood that this gas fire is applicable both for heating and
cooking purposes.
Dated this 1st day of April 1893.

Improvements in Gas Fires.
I, WILLIAM MCCAIG, of 665 Cathcart Road, Govanhill, Glasgow, in the
County of Lanark, North Britain, Tailor, 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:-—
My invention relates to improvements in gas fires and has for its object simplicity
and cheapness in construction and fitting, and a better glow of heat with less
consumption of gas.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings in the several
figures of which corresponding parts are marked with the same letters of reference.

The invention consists of a series of curved pipes A according to the size of
the fire place connected together by means of a plate B. On the top or flat
part of each of these curved pipes A there is an opening C in which there is
placed a small tube or injector D capped at each end. This tube or injector D
is provided with small pin-holes a (Figure 4) where it rests in the curved pipes
for the purpose to be hereinafter described. In the centre of this tube or injector D
there is also a tee E. for connecting the pipe E supplying the gas from the main.
This arrangement of pipes is fixed to the back of the brick G so that the two ends
of each of the curved pipes A, which are in a vertical position, will communicate with
the holes or openings H in the brick G which constitute the burner, the lower
openings being as near the bottom of the brick as possible so that the flame will
play against the very bottom of fuel and throw the reflection down below the
bottom of the fire place, as is the case in an ordinary coal fire. The brick and
piping is then placed in the fire place I, and the gas supply pipe coupled on.
I should here explain that I prefer the gas supply pipe to pass through the back
brick of the fire place, so that nothing offensive to the eye will be seen; or it may
pass up through the bottom of the fire place. I I fill up the front part of the fire
place with asbestos balls J, or other analogous material. When the gas is turned on
its passes from the supply pipe E into the tube or injector D and escapes through
the pinholes a into the curved pipes A. and it along with the air which enters the
curved pipes A at the openings C, passes out at the ends of the curved pipes A and
through the holes or openings H in the brick G, and out at the front, when it is lit,
and a regular glow of heat is given off. The upper part of the brick G lies at an
angle, and so enables the heat to be thrown back, and the front of it is also
corrugated or ribbed.
It is to be understood that this gas fire is applicable both for heating and
cooking purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed, I declare that what I
claim is :-
The general arrangement and combination of the parts constituting the gas fire
substantially as described and shown on the accompanying sheet of drawings.
