PROVISIONAL SPECIFICATION.
Improvements relating to Incandescent Gas Burners.
I, ROBERT HOLBROOK, of 4, Spring Bridge Ealing Broadway, in the County
of Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an attachment for fixing to the chimney support of gas
burners adapted for use with incandescent mantles, the object being to provide a
means of guiding the chimney when removing or replacing it to prevent damaging
the mantle.
The attachment consists of a split cylinder the two parts of which are hinged
together with a spring controlled hinge and are provided with projections or ears
which on being pressed together cause the cylinder to open and thus allow it to be
placed on or removed from the frame of the burner.
The cylinder may be made of metal or other suitable material and is of such a
size that it acts as a guide in removing or replacing the chimney.

I, ROBERT HOLBROOK of 4 Spring Bridge, Ealing Broadway, in the County of
Middlesex, 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 relates to an attachment for fixing to the chimney support of gas
burners adapted for use with incandescent mantles, the object being to provide a
means of guiding the chimney when removing or replacing it to prevent damaging
the mantle.
The attachment consists of a split cylinder the two parts of which are hinged
together with a spring controlled hinge and are provided with projections or ears
which on being pressed together cause the cylinder to open and thus allow it to be
placed on or removed from the frame of the burner.
The cylinder may be made of metal or other suitable material and is of such a
size that it acts as a guide in removing or replacing the chimney.
In the accompanying drawing which illustrates this invention :-
Figure 1 is a view showing the application of my invention.
Figure 2 is a view of the attachment alone.
Figure 3 is a view in plan thereof, and
Figure 4 is a view in plan showing the attachment open as in the act of being
placed around the chimney and on to its support.
Throughout the views similar parts are marked with like letters of reference.
The attachment or protector consists of a split cylinder A the two parts of which

page_text: are hinged together by a spring controlled hinge such as a. The abutting margins
or edges a¹ of the parts of the split cylinder A are preferably curved slightly
outwards as shown to facilitate the placing of the cylinder around the chimney of
the burner, but this is not obligatory. On each part of the split cylinder A is
formed or fixed an ear a². These ears are placed in such proximity to one another
that they can be conveniently pinched to bring them together and thus open the
split cylinder by a thumb and finger.
If desired the interior of the split cylinder may be lined with rubber, felt, or
like material.
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 :-
An attachment or protector for facilitating the removal of the chimneys of gas
burners using incandescent mantles constructed arranged and adapted to operate
substantially in the manner herein before set forth.
