PROVISIONAL SPECIFICATION.
An Appliance by which the Mantle of an Incandescent Gaslight,
along with its Supports and the Chimney, may be Removed,
giving Easy Access to the Burner.
I, HENRY FOSTER of 2 St. Leonard's Place, in the City of York, Surgeon,
do hereby declare the nature of this invention to be as follows:-
Its object is to enable the mantle of an incandescent gas light to be removed
easily and safely from the burner for the purpose of cleaning, or otherwise attending
to the said burner. The apparatus for attaining this object is constructed as
follows-
A tube of brass or other material, surrounds the incandescent gas-light burner,
and is bridged across by a strip of metal or other material, from some portion of
which ascends, descends, or passes through, a socket for the reception of the
"crutch" or other support, which upholds the mantle, the lower margin of which
last, surrounds the upper portion of the afore-mentioned tube. The said tube is
attached to the chimney gallery, which is so constructed as to admit of its being
removed, together with the chimney the crutch and the mantle, without disturbing
the burner and other parts, thus rendering the latter accessible, without having
to remove the mantle from the crutch, as is at present necessary, and reducing
thereby the risk of injury to the mantle, which is moreover further protected by
the non-removal of the chimney from its gallery.
Dated this Ninth day of December 1896.
HENRY FOSTER.
COMPLETE SPECIFICATION.
An Appliance by which the Mantle of an Incandescent Gaslight,
along with its Supports and the Chimney, may be Removed,.
giving Easy Access to the Burner.
I, HENRY FOSTER, of 2. St. Leonard's Place, in the City of York, Surgeon,
do bereby 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 :-
My invention relates to incandescent gas burners and has for its object to
enable the mantle to be removed easily and safely from the burner without.
detaching it from the crutch or other support from which the mantle is suspended,
as has been heretofore necessary when it is desired to clean or gain access to the
burner head.
According to my invention I employ an appliance which is capable of being
easily clipped or otherwise detachably connected to the burner, such appliance
being provided with means for supporting the crutch and preferably also with
means for supporting the chimney and the globe if the latter be employed.
In order that my said invention may be clearly understood and readily carried

page_text: accompanying drawings in which :-
Figure 1 is a vertical section of an incandescent gas burner provided with my
appliance.
Figure 2 is a vertical section of the appliance shewn in Figure 1, removed from
the burner.
Figures 3 and 4 respectively show an elevation and a plan of the said
appliance.
Figure 5 is an elevation of the appliance in a slightly modified form.
In all the figures A is a tube of brass or other suitable material which
surrounds the incandescent gas burner B when in position as shown in Figure 1.
The tube A is preferably split longitudinally as shown at a in Figures 3 and 4
in order that it may serve as a clip and adapt itself to burners of slightly different
diameters.
The upper end of the said split tube or clip is bridged across by a strip of
metal C or is otherwise formed to carry a socket D. adapted to receive the lower
end of the crutch E or other support which upholds the mantle F, the latter being
suspended in such a position that when the tube or clip A is applied to the burner
the mantle will occupy the usual position relatively to the burner.
The tube or clip A is attached to the chimney gallery G by means of the
legs H H. The said chimney gallery rests upon suitable supporting brackets
from which it can be freely lifted and it is so constructed as to admit of its
being removed from the burner together with the chimney J, the tube or clip A,
the crutch E, and the mantle F without removing the latter from its crutch or
disturbing the parts connected therewith. In some cases I also arrange the
gallery that carries the globe to be.removable simultaneously with the removal of
the said appliance.
In order to obtain access to the burner head it has hitherto been necessary to
remove the mantle from the crutch but by means of the above appliance the
burner head is rendered accessible without so doing and the risk of injury to the
mantle is thus materially reduced. Moreover the liability of the mantle to
become injured by the removal of the chimney from the gallery is also avoided as
such removal is rendered unnecessary with my appliance.
In order to maintain the mantle at a proper height relatively to the burner and
tube or clip A as above described, the aforesaid legs H H may be slightly bent
or straightened so as to allow the mantle to be raised or lowered relatively to
the burner.
I wish it to be understood that I do not confine myself to the precise construction
of appliance shewn in the accompanying drawings as any other detachable
appliance provided with means for carrying the crutch independently of the burner
will answer my purpose.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is :-
1. A detachable appliance for an incandescent burner provided with means
for carrying the mantle and the chimney in such a manner that these parts
can be removed from the burner-head without injury to the mantle for the
purpose specified.
2. The construction of the detachable appliance for use with an incandescent
burner substantially as described with reference to the accompanying drawings
and for the purpose specified.
