Improvements in and relating to Incandescent Gas Burners.
JABEZ JACKSON, Linton House, Starley Road, Coventry, Engineer, do hereby
declare the nature of this invention to be as follows:-
I provide an arrangement by which the mantle of an incandescent gas burner
can be raised or lowered at will, thus enabling the mantle to be brought into
the best position for ensuring a maximum incandescency.
To carry out this idea I provide an arrangement by which the crutch that
supports the mantle to such burner, can be raised or lowered either by using a
stud, screw, spring, pin, pinion, or otherwise.

Improvements in and relating to Incandescent Gas Burners.
JABEZ JACKSON, of 33, Cope Street, Coventry, late of Linton House, Starley
Road, Coventry, 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:-
I provide an arrangement by which the mantle, of an incandescent gas burner,
can be raised or lowered at will, thus enabling the mantle to be brought into
the best position for ensuring a maximum incandescency.
To carry out this idea I provide an arrangement by which the crutch that
supports the mantle to such burner, can be raised or lowered either by using a
stud, screw, spring, pin, pinion, or otherwise.
To accomplish this arrangements by which the crutch in the centre of the said
burner can be raised & lowered as desired. When using a stud screw to grip the
mantle support, the said stud screw will have a milled or other head, on the
outer end which projects outside the burner to enable the said crutch to be
retained at any height desired; the socket being tubular. When the socket is
not sufficiently long to enable the utmost desired mantle lowering, it must be
open at the base, such a device is shown in Fig. 1 of the drawings attached.
When using a spring to secure the same result, I provide an attachment as
shown in drawing Figures 2, 3, & 4. In Fig. 2 I show a modification in which
the same end is secured by the use of an aditional spring, fixed at one end to the
socket having a pin on its other end which bears against the mantle crutch to
keep it in position.

page_text: In Fig. 3 I show a modification in which the same end is attained, but in
which the spring is arranged in a different position.
In Figure 4 I show an hollow in the crutch holder, in which is contained a
circular spring, which grips upon the mantle support when it is forced through
it & slides on it when force is used to push it either one way or the other.
In some cases I might use a pinion, which engages with the mantle holder
raising & lowering in the same way as the wick of a lamp, or a rack.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
-
The means for allowing of raising & lowering the crutch in the centre of an
incandescent gas burner as set forth herein.
