Improvements in Gas Appliances for Heating Purposes.
WILLIAM HENRY TASKER 78 North Street, Scarborough Exhibitor and WILLIAM
WHITEHEAD 3 Hanover Road, Scarborough Electrical Engineer do hereby declare the
nature of this invention to be as follows:
:-
In gas appliances used for heating purposes thus far employed a separate apparatus
is used which is connected to the gas supply by a piece of flexible or other tube. Our
invention consists of means and devices for making use of ordinary gas pendants or
fittings without removal of the ordinary lighting burners or in any way interfering
with the said pendants or fittings and we carry it out in the following way.
In the first place we produce a tube of brass or other metal sufficiently large to pass
easily over the ordinary lighting burner, such tube at its lower extremity having
three or more V shaped pieces cut out in such a manner as to form three or more
points, forks, or claws, the said tube being also of such substance and thickness,
as to admit of the said points, forks, or claws being readily pressed or bent inwards
in order to grip on to the part of an ordinary gas pendant or fitting where the gallery
is fixed which usually supports or carries the globe, and inside of which the burner
for lighting is usually screwed or placed.
In the said tube above the said points, forks, or claws we have three or more
elongated perforations or holes of suitable width and in length about one third the
entire length of the tube, such perforations or holes being for the purpose of admitting
air into the said tube.
Between the said points, forks, or claws and the said elongated perforations or holes,
a shoulder or projecting ring is placed or formed round the tube, the use of which is to
stop the downward movement of an outside tube or sleeve which is immediately to
be described.
In addition to the said inner tube we have an outer tube or sleeve which slides on
the inner tube friction tight, the use of which outer tube or sleeve is to open or close
the said elongated perforations or holes as may be needed for perfect combustion.
The outer tube may be at its upper end left completely open, or preferably we cut
certain or other shaped pieces out to enable us to form a rose or other shape of
flame by bending the points inwards towards the centre of the tube.
In all atmospheric burners hitherto in use where the combustion flame is near to the
gas supply, there has been a tendency of the flame to strike down the tube and to light
at the supply hole at the bottom of the tube and particularly so when too much air
has been admitted. In our invention as the outer tube or sleeve is moved upwards to
open the elongated perforations or holes it lengthens the tubes in telescope fashion and
thus carries the combustion flame further away from the gas supply, and prevents the
flashing or striking of the flame down the tube.

Improvements in Gas Appliances for Heating Purposes.
We, WILLIAM HENRY TASKER, of 78, North Street, Exhibitor, and WILLIAM
WHITEHEAD, of 3, Hanover Road, Electrical Engineer, both of Scarborough, in the
County of Yorkshire, 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:—
In gas appliances used for heating purposes thus far employed, a separate apparatus
is used which is connected to the gas supply by a piece of flexible or other tube.
Our invention consists of means and devices for making use of ordinary gas-
pendents or fittings without removal of the ordinary lighting burners, or in any way
interfering with the said pendents or fittings.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1 & 5 are side elevations showing the burner applied to an ordinary gas
bracket. Figs. 2 & 6 are plans respectively of Figs. 1 & 5. Figs. 4 & 8 are
respectively sectional plans of Figs. 3 & 7. Figs. 3 & 7 are vertical sections
respectively of Figs. 1 & 5.
с
In carrying out our invention and referring to Figs. 1 & 5. we produce a tube a
preferably of brass or other metal sufficiently large to pass easily over the ordinary
lighting burner b, such tube at its lower extremity having three or more V or other
shaped pieces cut out in such a manner, as to form three or more points, forks or
claws c and air passages between same, the said tube a being also of such substance
and thickness as to admit of the said points, forks or claws c, being readily pressed or
bent inwards in order to grip on to the part d of an ordinary gas pendent or fitting e
where the gallery is fixed which usually supports or carries the globe and inside of
which the burner & for lighting is usually screwed or placed..
In the said tube a above the said points, forks or claws c we form three or more
elongated perforations or boles of suitable width and in length about one third the
entire length of the tube a, such perforations or holes f being for the purpose of
admitting air into the said tube a. Between the said points, forks or claws c and the
said elongated perforations or holes f₁ a shoulder or projecting ring g is placed or
formed round the tube a the use of which is to stop the downward movement of an
outside tube or sleeve a', arranged to slide friction tight on the tube a, the use of
which outer tube or sleeve a' is to open or close the said elongated perforations or
holes f, as may be needed for perfect combustion.
The said outer tube or sleeve a¹ may be at its upper end left completely open or
preferably we cut certain V or other shaped pieces out to enable us to form a rose
or other shape of flame by bending the points inwards towards the centre of the tube
and thus forming a slot or mouth h.
In all atmospheric burners hitherto in use, where the combustion flame is near to
the gas supply, there has been a tendency of the flame to strike down the tube and to
light at the supply hole at the bottom of the tube, and particularly so when too much
air has been admitted. In our invention, as the outer tube or sleeve a¹ is moved
upwards to open the elongated perforations or holes f¹ it lengthens the tubes a, a¹, in
telescope fashion and thus carries the combustion flame further away from the gas
supply and prevents the flashing or striking of the flame down the tube.
Figs. 5-8. represent a modification of our invention which consists in forming
the tube a, a in one piece and the points, forks or claws c to grip the burner b itself
instead of the part d of the gas bracket e. To this end we form the points, forks or
claws C, above the ring or shoulder g, by punching the same out of the lower end of
the tube a and bending the same inwards, thus forming at the same time the elongated
perforations or holes I, necessary for the admittance of air into the tube a. The said

page_text: points, forks or claws c are each formed with an indent c¹ which serves as a stop in
placing the tube a onto the burner 6, thus bringing it in its proper position
for use.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
"In gas appliances for beating purposes."
1st. The use of and application to an ordinary gas pendent or fitting e, of a
removable tube a, a', the lower extremity of which is formed with points, forks
or claws c and air passages f,f, to respectively grip the gas pendent or fitting e
and admit air into the tube a, a, and the upper extremity of which is formed
with a slot or mouth h, to produce a rose or other shaped flame, substantially as
set forth.
2nd. Admitting air into the tube a, a¹ simultaneously from the side as well as from
the bottom thereof, by means of the passages f,f, the bottom passages conducting
the air between the upper passages f¹, so as to effect a uniform mixture of the gas
and air, and thus more perfect combustion, substantially as set forth.
