Improvements in Gas Fires, Cooking Stoves and other like Heating
and Cooking Appliances.
I WILLIAM MOCAIG of 430 Victoria Road in the County of the City of Glasgow,
North Britain, 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 which relates to improvements in gas fires and cooking appliances
has for its object the production of a burner and connections which will resist all
possibility of firing or lighting back even when abnormal means are adapted such
as causing a forced draught to enter the nozzles by the employment of bellows or
analogous blowers; consequently there can be no whiteness in the flame of the
burners, no offensive smell, no carbonization or corrosion of parts; and incandescence
at the extremities is as perfect as at the centre. The hissing noise incidental to
fires presently in use is by virtue of my improvements entirely obviated by
the equalizing and distribution of the gas through the respective series of mixing
chambers.
In order that my invention may he properly understood and readily carried into
effect I have hereunto appended one explanatory sheet of drawings in the several
figures of which corresponding parts are marked with the same letters of
reference.
Fig 1 is a front elevation. Fig 2 is a plan of the same partly in horizontal section
and Fig 3 is a transverse vertical section of burner of a gas fire or analogous heating
appliance made in accordance with and constituting my invention.
The gas in order to supply the burner is conveyed by the pipe A into an
injector-chamber B, the face plate C of which is provided with a number of jets D,
which open into an air chamber B', centrally opposite a number of cylindric mixing
chambers E. These chambers E, in the direction of their length are horizontal
and pass from the back to the front of the burner. The gas passes from the
injector-chamber B aforesaid, through the air chamber B¹ and mixing chambers E
to the front of the burner where it Hows down into a horizontal chamber F running
transversely from end to end. Immediately from this chamber F the nozzles G, for
the ignition of the gas, are led. The fire-brick, H and ball fuel I are placed relatively
with the burner as seen in Fig 3.
To make grates more readily adaptable for the reception of gas fires embodying
my improvements, the front fire bars, instead of being supported in groove pieces
formed at both sides of the framework of the grate as is presently the case, may be
supported in similar groove pieces formed on the burner of the gas fire at the parts
marked J, Figs. 1 and 2 of the drawings.
Although I have shown and described the burner as applied to a gas fire of a
domestic grate it is to be understood that it is equally applicable to other forms
of heating appliances as well as to gas stoves and cooking apparatus generally.

page_text: 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:-
..
The general arrangement and combination of parts substantially as described and
shown on the accompanying sheet of drawings.
