PROVISIONAL SPECIFICATION.
Improvements in Lamp Chimneys and their Supports.
I THOMAS HITCHCOCK AMBROSE of Waveney Mansions, Canfield Gardens,
South Hampstead, London, Gentleman, do hereby declare the nature of this
invention to be as follows :-
The object of this invention is to effect or facilitate the lighting of lamps without
removing their chimneys, whereby both time and labor are economized and the
liability to breakage of said chimneys by their frequent removal and replacement
is reduced.
The invention consists in a lamp chimney, usually made of glass, provided with
a hole in its side at or near the level of the upper end of the lamp burner when
the chimney is in place, to admit of the introduction of a lighted match or other
"lighter" through the side of the chimney, for the purpose of inflaming the
exposed end of the wick projecting through the burner. The invention also
consists in the combination with such a laterally perforated lamp chimney, of the
lamp burner and chimney support or holder, the latter being constructed as usual
or otherwise, so that it will present a claw-like or broken surface alike to hold the
chimney in place, and, by the turning of the chimney in its seat, to close the
lighting aperture in the side of the chimney after the lamp wick has been lit,
and so prevent air from entering through the lateral aperture in the chimney to
interfere with the draft or burning of the lamp, substantially as hereinafter
described.
The lamp burner which may be of any suitable form or construction is provided
with a metallic chimney holder or support, having claws or projections which on
being suitably bent serve to hold the chimney in place but which also perform
another and important function in connection with the laterally perforated chimney.
The perforation may be of oblong or oval shape in an upward direction but might
be of any other suitable shape, and is made approximately at or near the level of
the upper end of the burner up through which the wick projects and is also at or
near the level of the close fitting claws or projections of the chimney holder s0
that when the lateral perforation is open, a lighted match or other lighter may be
inserted through said perforation to light the exposed portion of the wick and after
the lamp has been lit the chimney is turned or rotated to bring its lateral aperture
under close cover of the claws or projections of the chimney fender or support, and
so prevent the air from entering through said lateral chimney aperture to interfere
with the draft or proper burning of the lamp.
In some cases, the lamp chimney holder or support may be made to rotate or
turn to carry its claws or projections upon or away from the lateral lighting
aperture in the chimney, instead of turning the lamp chimney in its seat. This
would be the equivalent of the construction herein before described.

1 THOMAS HITCHCOCK AMBROSE, of Waveney Mansions, Canfield Gardens,
South Hampstead, London, Gentleman, 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 :-
The object of this invention is to effect or facilitate the lighting of lamps without
removing their chimneys, whereby both time and labor are economized and the
liability to breakage of said chimneys by their frequent removal and replacement
is reduced.
The invention consists in a lamp chimney, usually made of glass, provided with
a hole in its side at or near the level of the upper end of the lamp burner when
the chimney is in place, to admit of the introduction of a lighted match or other
lighter" through the side of the chimney, for the purpose of inflaming the
exposed end of the wick projecting through the burner. The invention also
consists in the combination with such a laterally perforated lamp chimney, of the
lamp burner and chimney support or holder, the latter being constructed as usual
or otherwise, so that it will present a claw-like or broken surface alike to hold the
chimney in place, and, by the turning of the chimney in its seat, to close the
lighting aperture in the side of the chimney after the lamp wick has been lit,
and so prevent air from entering through the lateral aperture in the chimney to
interfere with the draft or burning of the lamp, substantially as hereinafter
described and more particularly pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.

Figure 1 represents a perspective view in elevation of a lamp and its chimney,
embodying my invention;
Figure 2 is a view in elevation in part, of the same at right angles to Figure 1,
with a lighted match as applied to the wick of the lamp; and
Figure 3 is a horizontal or transverse section mainly upon the line 3-3 in
Figure 1.
A, is the body of the lamp which may be of any suitable shape, material or
construction, B the burner of the lamp, also of any suitable form or construction,
with a metallic chimney holder or fender-like support C, having claws or pro-
jections b, which on being suitably bent serve to hold the chimney D, in place but
which also perform another and important function in connection with the laterally
perforated chimney D. The lateral chimney perforation d is here shown as of
oblong or oval shape in an upward direction but might be of any other suitable
shape, and is made to stand approximately at or near the level of the upper end of
the burner B up through which the wick e projects and is also at or near the level
of the close fitting claws or projections 6 of the fender or chimney holder C, so
that, when the chimney D in its seat or holder C has the lateral perforation d
open, a lighted match or other lighter f may be inserted through said perforation
to light the exposed portion of the wick e, and after the lamp has been lit the
chimney D is turned or rotated to bring its lateral aperture d under close cover of
the claws or projections 6 of the chimney fender or support C, and so prevent the
air from entering through said lateral chimney aperture d to interfere with the
draft or proper burning of the lamp.
b
In some cases, the lamp chimney holder or support C may be made to rotate or
turn to carry its claws or projections & upon or away from the lateral lighting
aperture d in the chimney, instead of turning the lamp chimney in its seat. This
would be the equivalent of the construction herein before shown and described.

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,―
1. A lamp chimney provided at or near its lower end with a lighting aperture in
its side, substantially as specified.
2. The combination, with a lamp burner, of a laterally perforated lamp chimney,
the perforation in which is adapted to give ingress through the side of the chimney
to a lighted match or lighter for inflaming the wick passing upwardly through the
burner, essentially as described.
3. The combination, with a lamp burner, and lower chimney support of perforated
or broken construction on its sides, forming claws or projections for holding the
lamp chimney in place, of a lamp chimney provided with a lighting aperture in
its side under cover and exposure of and by said claws or projections, substantially
as and for the purposes herein set forth.
