Improvements in or in connection with Gas Burners.
I, THOMAS HOLLIDAY, Managing Director of Read Holliday & Sons Limited, of
Upper Head Row, Huddersfield, in the County of York, Manufacturing Chemist,
do hereby declare the nature of this invention to be as follows:-
This invention. relates to burners or connections therewith for burning rich gas,
such as acetylene and is designed to enable the same to be burned along with air for
illumination and consists in the combination with an ordinary gas burner, more
especially the description of burner known as union jet, of a small injector the motive
force of which is the rich gas to be diluted and which force draws in air through
apertures made for the purpose, the quantity of air being regulated by the difference
in size of the gas jet and the opening opposite to it through which the gas and air are
injected by the gas jet and by the pressure of the gas.
The distance between the gas jet and the opening being sufficient to allow the
entrance of the air, for which purpose apertures are made between the two.
The object of the present improvements is to facilitate the regulation of the supply
of the gas and to effect partial discontinuance of-supply.
In arrangements at present in use the diminution of supply of the gas
reduces the force of orificial pressure so much that sufficient air is not drawn into
mixture with the gas to ensure complete combustion and deposit of soot takes
place.
According to my invention I effect the diminution of supply of gas and
reduction of the orifice for gas delivery by one and the same means-by mean's
of a needle, or equivalent pointed piece fitting an orifice in the gas supply pipe.
The relative movements of this needle and of its seat so as to form the valve may
be effected in various ways according to the requirements of the case. For instance
the needle may be formed with a screw part and be actuated within a certain limited
range of movement (determined by stop parts).
Or the needle may be fixed and the seating portion of the valve be so moved.
Or the needle (or the seating parts) may be moved by a cam or eccentric action.
In cases where a gallery is used to support a chimney, or chimney and globe, or a
globe or cover alone, the gallery, or like part, may be mounted on the parts carrying
the seating and by the rotation thereto imparted by the hand the seating is relatively
moved to or from the needle increasing, or diminishing gas supply injected into the
mixing chamber whence, mixed with air, the combustible fluid. passes to the burner' or
point of combustion. To prevent escape of the gas under pressure between the
movable regulating part and the pipe of supply, whether threaded, or fitted otherwise
I prefer to pack the same and to construct the same so that play to and from is only
allowed ample for opening and closing the needle valve.
A convenient construction is to form a thread on the supply pipe engaged by'a
corresponding thread on movable part, a shoulder on the latter seating itself on the end
of the supply pipe when the valve is fully closed. Below the screw the movable part
is packed to the pipe and a packing piece or ring secures the packing and serves to
control extent of movement outwardly and prevent dislocation of the parts.

Improvements in or in connection with Gas Burners.
I THOMAS HOLLIDAY, Managing Director of Read Holliday & Sons, Limited, of
Upper Head Row, Huddersfield, in the County of York, Manufacturing Chemist 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 relates to burners or connections therewith for burning rich gas,
such as acetylene and is designed to enable the same to be burned along with air for
illumination and consists in the combination with an ordinary gas burner, more
especially the description of burner known as union jet, of a small injector the motive
force of which is the rich gas to be diluted and which force draws in air through
apertures made for the purpose, the quantity of air being regulated by the size of the
apertures admitting air or by the difference in size of the gas jet and the opening
opposite to it through which the gas and air are injected by the gas jet and by the
pressure of the gas.
The distance between the gas jet and the opening being sufficient to allow the
entrance of the air which may be admitted through apertures on a level with or below
the gas jet.
The object of the present improvements is to facilitate the regulation of the supply
of the gas and to effect partial discontinuance of supply..
In arrangements at present in use the diminution of supply of the gas reduces the
force of orificial pressure so much that sufficient air is not drawn into mixture with the
gas to ensure complete combustion and deposit of soot takes place.
According to my invention I effect the diminution of supply of gas and reduction
of the orifice for gas delivery by one and the same means-by means of a needle, or
equivalent pointed piece fitting an orifice in the gas supply pipe. The relative
movements of this needle and of its seat so as to form the valve may be effected in
various ways according to the requirements of the case. For instance the needle may
be formed with a screw part and be actuated within a certain limited range of
movement (determined by stop parts).
Or the needle may be fixed and the seating, portion of the valve be so moved.
Or the needle (or the seating parts) may be moved by a cam or eccentric action.

DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 show sectional view and outside view respectively of my improved
apparatus for burning acetylene gas mixed with air.
Fig. 3 shows a sectional view of a modified form of the apparatus and
Fig. 4 shows a detail of the same.
Referring to Figs. 1 and 2, a screws into the gas fitting and is provided with a small
hole b for the exit of the gas and must be accurately adjusted so that the jet of gas is
projected through the hole c. d, d are holes to admit air which is drawn with the gas
through the constricted tube c into the mixing chamber f from which the mixture
issues through the gas burner g ready for ignition.
A union jet burner may be used or one from which the gas issues through a fine
slit.
A needle i controls the extent of the orifice band thereby regulates the supply of
gas. This needle i may be inserted into or withdrawn from the orifice b by means of
the screw threaded spindle and milled head. A nut or cap k prevents the needle
being, withdrawn too far. A washer or disc k¹ of suitable material enables the joint
to be made gas-tight, the nut k serving to hold the disc securely on its seating.

page_text: In cases where a gallery is used to support a chimney, or chimney and globe, or a
globe or cover alone see Fig. 3, the gallery N, or like part, may be mounted on the
parts a carrying the seating b and by the rotation thereto imparted by the hand the
seating is relatively moved to or from the needle H increasing, or diminishing, gas
supply injected through the hole c into the mixing chamber f whence, mixed with air,
the combustible fluid passes to the burner g or point of combustion.
To prevent escape of the gas under pressure between the movable regulating part a
and the pipe of supply I, whether threaded, as shown, or fitted otherwise I prefer to
pack the same, as by packing O, and to construct the same so that play to and from
is only allowed ample for opening and closing the needle valve.
A convenient construction is to form a thread M on the supply pipe engaged by a
corresponding thread on movable part, a shoulder on the latter seating itself on the
end of the supply pipe I when the valve is fully closed. Below the screw the movable
part is packed to the pipe and a packing piece or ring P secures the packing O and
serves to control extent of movement outwardly and prevent dislocation of the
parts.
The needle H is carried by a disc K in the end of the gas supply pipe, holes
being formed in said disc for passage of the gas. The packing O is secured in place
by a screw gland Q.
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 :-
1. An apparatus for burning acetylene gas consisting of an ordinary gas burner, a
small injector to draw in air and force out the mixture and a point or pin which can
be drawn in or out of the small orifice through which the gas enters the apparatus
to regulate the supply, substantially as set forth.
2. The construction, or arrangement in combination of parts, of a "burner" for
use in the combustion of acetylene gas wherein the diminution of supply of gas and
the reduction of the size of the orifice of delivery is effected by one and the same
means, substantially as set forth.
