I, WILLIAM 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 for "IMPROVEMENTS IN CAPS OR
CONSUMERS" FOR GAS AND OTHER GLOBES AND CHIMNEYS a communication to
me from abroad by Paul Costes, Mechanic, of 4 Rue de la Nation and Auguste
Vervin, Gentleman, of 6 Rue de l'Equerre, Bourges, France to be as follows:-

This invention relates to improvements in caps or'" consumers" for gas and
other globes and chimneys. These caps or consumers have heretofore been
formed in one with the metal clips by which they are fixed to the globe or chimney,
or they have been soldered or rivetted to the metal rings on. which the said caps
are mounted. The great objection to this arrangement is that the metal rings,
clips, etc are directly exposed to the action of heat whereby the metal loses its
flexibility, rendering it impossible to fit the same cap to globes or chimneys of
different diameters; moreover, the metallic supports become distorted by the action
of heat and are soon rendered unserviceable, and when one of the supports fails as
is often the case, the cap being no longer supported by both arms, falls upon and
breaks the globe or chimney. Lastly it has been necessary, in order to clean the
cap, to remove it together with its support, which interfered with the cleaning,
besides the liability to put the support out of shape.

The essential feature of novelty in the cap consists in providing it with a knob,
stud, or button c. of any suitable form on its exterior to engage with a corresponding
part of the metal support d. Either a single central stud or boss may be employed
as in figure 1, or several studs may be used as in figure 5, the stud or studs being

either attached to a ring or collar encircling the stud, when a single stud only is
used, or forked at their extremities to embrace the studs, when a series is used. To
place the cap or consumer upon a globe or chimney, it is simply necessary to
expand the ring d as shown in figuré 4, insert the stud c and then close the ring
upon it by means of the arms affixed thereto so as to bring them to the position
shown in figures 2 and 3, the ring or collar is thus closed upon the stud c by which
the cap is in this manner suspended as shown in figure 1. The metal support is
thus uninfluenced by the heat which acts solely upon the cap, and as the cap is
only in contact with the support at the point of attachment c, said support is no
longer liable to injury by heat, retains its flexibility and will last for an indefinite
time. This mode of protecting the metallic support from the action of heat by
utilising the cap as a screen therefor constitutes one of the main features of the
invention.
To clean the cap by bringing the two arms connected to the two halves of the
supporting ring d together, so as to open the ring, the cap is readily removed
leaving the support in place upon the globe or chimney. The cleaning of the cap
is in this manner much more easily effected.
In caps having several studs or knobs as in the example shown in figure 5, the
supporting arms d are sufficiently flexible to allow of detaching their forked or
hooked ends from the studs and thus readily removing the cap.
Figures. 7 and 8 show perspective views of different forms of globes provided
with the improved suspended cap before described Owing to the cap being
suspended from the exterior, there need be no central aperture with ring as in
certain caps now used which is liable to become blackened and prevents some of
the light being reflected, whereas with this improved cap owing to its being
enamelled over its entire surface and there being no metallic parts in contact with
its interior, the whole of the light is reflected.

This Invention relates to improvements in caps or "smoke consumers
for gas
and other globes and chimneys. These caps or "consumers" have heretofore been
formed in one with the metal clips by which they are fixed to the globe or
chimney or they have been soldered or rivetted to the metal rings on which the
said caps are mounted. The great objection to this arrangement is that the metal
rings, clips, etc. are directly exposed to the action of heat whereby the metal loses
its flexibility rendering it impossible to fit the same cap, to globes or chimneys, of
different diameters. Moreover, the metallic supports become distorted by the
action of the beat and are soon rendered unserviceable, and when one of the
supports fails as is often the case the cap being no longer supported falls upon and
breaks the globe or chimney. Lastly, it has been necessary in order to clean the
cap to remove it together with its support which interfered with the cleaning
besides being liable to put the support out of shape.

All the above objections are obviated by the employment of the improved cap or
61 consumer " of this Invention, which is represented by way of example in the
accompanying drawings; figure 1. representing a sectional view of a cap or
consumer". attached to a globe by means of a jointed support, and figure 2. a plan
of said cap, with its three armed support. Figure 3 is a separate plan of the
support in the closed position, parts of the arms being broken away. Figure 4 is
a plan of the 'same in the open position. Figure 5 shows a cap or " consumer
provided with three studs for the attachment of the supporting arms. Figure 6
shows the cap as applied to a gas chimney. The same letters of reference represent
the same parts in all the figures.

a is the gas, or other, globe or chimney b is the cap or "consumer" of porcelain,
glass, or other suitable material, the form and dimensions of which cap may be
varied as desired. The essential feature of novelty in the cap consists in providing
it with a knob, stud, or button, c of any suitable form,.on its exterior to engage
with a corresponding part of the metal support d. Either a single central stud or

the stud or studs being moulded in one with the cap in making, or attached by
screwing or otherwise. d is a metallic hinged ring or collar provided with arms
resting upon the upper edge of the globe or chimney and serving to support the
cap b by means of the ring or collar which embraces a central knob or stud c upon
said cap. Or, the ring or collar may be dispensed with and the arms d be forked
at their extremities to embrace a series of studs c disposed around the cap as shown
in figure 5.

To place the cap or "consumer" upon a globe or chimney, it is simply necessary
to expand the ring d as shown in figure 4, insert the stud c and then close the ring
upon it by means of the arms affixed thereto so as to bring them to the position
shown in figures 2 and 3; the ring or collar is thus closed upon the stud c by
which the cap is, in this manner, suspended as shown in figure 1. The metal
support is thus uninfluenced by the heat which acts solely upon the cap, and as the
cap is only in contact with the support at the point of attachment c said support
is no longer liable to injury by heat, retains its flexibility, and will last for an
indefinite time. This mode of protecting the metallic support from the action of
heat by utilizing the cap as: a screen therefor, constitutes one of the main features
of the Invention. To clean the cap, the two arms connected to the two halves of
the supporting ring & are brought together so as to open the ring, and the cap is
readily removed leaving the support in place upon the globe or chimney. The
cleaning of the cap is in this manner. much. more easily effected.
In caps having several studs or knobs as in the example shown in figure 5, the
supporting arms d are sufficiently flexible to allow of detaching their forked or
hooked ends from the studs and thus readily removing the cap.
Figures 7 and 8 show perspective views of different forms of globes provided
with the improved suspended cap before described. Owing to the cap being
suspended from the exterior, there need be no central aperture or metallic ring as
in some caps now used which is liable to become blackened and prevents some of
the light being, reflected, whereas with this improved cap, owing to its being
enamelled over its entire surface and there being no metallic parts in contact with
its interior or edges the whole of the light is reflected. The liability to breakage,
due to the unequal heating of ordinary caps for ceramic material and their metallic
supports is also avoided.
Having now particularly described, and ascertained the. nature of the said
Invention and in what manner the same is to be performed, I declare that what
I claim is
