I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for IMPROVEMENTS

IN CONSUMERS OR CAPS AND REFLECTORS FOR GAS AND OTHER GLOBES AND
CHIMNEYS a communication to me from abroad by Paul Costes Mechanic and
Auguste Vervin Gentleman both of Bourges (Cher) France, to be as follows:-
This Invention relates to improvements in "consumers

or caps for gas and
These caps whether made of metal or mica are usually supported above the globe
or chimney by means of flexible legs which render them very unstable and which
are soon rendered unserviceable by the action of the heat from the burner More-
over these caps are not adapted for being placed upon chimneys of different sizes
and thicknesses, as they require to fit properly thereon. The object of the present
Invention is to obviate the above objections by providing the "consumer"
or cap
with rigid forked or pronged legs or supports which may be formed in one with
the cap, the prongs being at a sufficient width apart to admit of their being placed
upon chimneys of all sizes and thicknesses as well as on globes by slightly varying
their form or arrangement. The caps and their supports may be made of any
suitable refractory material such as porcelain, earthenware, glass, mica enamelled
or other metal &c.

The invention is illustrated in the accompanying drawing which shows several
examples of the improved consumers or caps. Figure 1 represents a cap or
reflector a, supported on, three or more legs b, b fitting on the outside of the
chimney e and each provided with a lug or projection m resting on the top of said
chimney. Figure 2 shows the same cap or reflector applied to a globe k, the
lugs m, being in this case on the outside and the legs b, b, on the inside of the
globe Figure 3 shows the cap applied to another form of globe. Figure 4 shows
the cap provided with metallic legs or supports b, b. Figure 5 shows the legs or

show the legs or supports formed with bent or cranked ends d, as a substitute for
the lugs m.
The same letters of reference represent the same parts in all the figures. The
cap is preferably made in the form of a conical or domed shaped reflector as shown.
The legs or supports b are so arranged that the cap e, shall be sufficiently near
the glass e, to limit the admission of air and thus avoid producing too strong a
draught as in existing caps, which increases the expenditure of gas without
improving the light.
In making the improved cap of porcelain or other non metallic refractory material
with the legs or supports in one piece therewith, the latter are strengthened and at
same time held in position during the firing by a ring f, figure 5.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of, this Invention (a communication to me
from abroad by Paul Costes, Mechanic, and Auguste Vervin, Gentleman, both of
Bourges (Cher) France, 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 improvements in "consumers" or caps for gas, and
other globes, and chimneys. These caps, whether made of metal, or mica are
usually supported above the globe or chimney by means of flexible legs, which
render them very unstable and which are soon rendered unserviceable by the
action of the heat from the burner. Moreover these caps are not adapted for
being placed upon chimneys of different sizes and thicknesses, as they require to fit
properly thereon. The object of the present Invention is to obviate the above
objections by providing the "consumer" or cap with rigid forked, or pronged legs
or supports, which may be formed in one with the cap, the prongs being at a
sufficient width apart to admit of their being placed upon chimneys of all sizes,
and thicknesses as well as on globes, by slightly varying their form or arrangement.
The caps and their supports may be made of any suitable refractory material, such
as porcelain, earthenware, glass, mica, enamelled, or other metal &c.

The invention is illustrated in the accompanying drawing which shows several
examples of the improved "consumers or caps. Figure 1 represents a cap or
consumer a supported on three or more legs b b, fitting on the outside of the
chimney e and each provided with a lug or projection m resting on the top of said
chimney. Figure 2 shows the same cap or reflector applied to a globe k, the
lugs m, being in this case on the outside, and the legs 6b on the inside of the
globe. Figure 3 shows the cap applied to another form of globe. Figure 4, shows
the cap provided with metallic legs or supports b b. Figure 5 shows the legs or
supports bb as made of porcelain or other analogous material. Figures 6, 7 and 8
show the legs or supports formed with bent or cranked ends d, as a substitute for
the lugs m. The same letters of reference represent the same parts in all the
figures. The cap is preferably made in the form of a conical or dome shaped
reflector as shown. The legs or supports b are so arranged, that the cap a shall be
sufficiently near the chimney e to limit the admission of air, and thus avoid pro-
ducing too strong a draught, as in existing caps, which increases the consumption
of gas without improving the light. In making the improved cap of porcelain, or
other non-metallic refractory material with the legs or supports in one piece
therewith, the latter are strengthened, and at same time held in position during
the firing by a ring f, figure 5.

page_text: 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
A "consumer," cap, or reflector for gas and other globes, and chimneys, having
rigid supports, formed in one piece, with the "consumer," or cap, or separately, and
either made of the same, or different material, said support consisting of any
suitable number of legs b, formed either with forked ends c, bent or cranked ends d,
or prongs, or lugs m, resting on the outside or inside edges of the globe or chimney,
all as hereinbefore described and represented in the accompanying drawings, for
the purpose specified.
