PROVISIONAL SPECIFICATION.
Improvements connected with Incandescent Gas Lamps and Burners.
RICHARD CROWE, 25, Williamson Street, Liverpool, in the County of Lancaster,
Jewellers' Manager, do hereby declare the nature of this invention to be as
follows:-
A new and improved temporary holder or support, for the purpose of temporally
holding and supporting the Incandescent mantle and its rod when off the burner.
The object of this invention is the supplying of a temporary support to hold the
rod and mantle used in connection with the atmospheric or Bunsen gas burner, the
combination of which is known as the Incandescent gas light, whilst such mantles
are in use, and for the purpose of allowing the burner portion to be cleaned; a process,
which, under certain conditions becomes absolutely necessary, if the best results are
to be obtained from the combined burner and mantle.
The invention consists of a holder or support made in any suitable material, in the
form of a short cylindrical pedestal, broad at the base, or other suitable shape, and
having a hole drilled or made by any suitable means in the centre of upper end, and
of suitable size and depth, in which the lower end of the rod which supports the
aforesaid mantle (on the burner) can be readily placed after removal from the burner,
and left standing in precisely the same manner, as it stood on the burner until again
wanted.

COMPLETE SPECIFICATION.
Improvements connected with Incandescent Gas Lamps and Burners.
I, RICHARD CROWE, of 25, Williamson Street, in the City of Liverpool, Jewellers'
Manager, 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:-
It has been found from experience, and after close observation, that to obtain the
best results from that combination of an atmospheric gas burner and a refractory
mantle known as the "incandescent gas light," the meshes of the wire gauze, stretched
across the exit of the gas and air mixing chamber, must be kept quite free from dust,
fluff, and such like floculent material, always present in the atmosphere, and which is
drawn into the mixing chamber during the admixture of the gases. If such dust
and fluff is allowed to accumulate on the gauze, insufficient ventilation is afforded to
the flame, and the mantle becomes blackened with unconsumed carbon. To remedy
this defect the mantle is removed-on its supporting rod-from the burner, and the
D971

page_text: gauze is then brushed with a fairly stiff brush. If, however, the mantle rod is held
in the hand, the mantle is very liable to become damaged, and it is to provide a
temporary holder or support for the mantle and rod, whilst removed from the burner,
that my invention has for its object.
Such a holder or support-which I prefer to term a "Mantle Tower"-according
to my invention is in the form of a truncated cone, having a broad base, and a socket
to receive the mantle rod end. The tower may be made of any suitable material,
such as sheet or cast metal, or wood, or partly metal and partly wood, moulded and
burnt clay, glass, or earthenware, papier mache, celluloid, or their equivalent, whilst
the socket in the upper part of the tower may be fashioned in different ways.
In the drawing hereto annexed,
Figure 1 is a sectional view of a mantle tower according to my Invention, shewing
the method of lifting the rod and mantle onto and off the tower.
Figure 2 is a side view of the tower, and
Figure 3 is a plan thereof.
It will be seen that the tower a consists of thin sheet metal, pressed into the form
of a truncated cone, with a broad base b, and a cupped depression c in the upper part of
the tower. In the centre of the depression c is formed an aperture d. Within the
tower there is provided a cup e, which is inserted from below, and secured by solder.
The cup e terminates in a socket e¹, which is directly below the aperture d. The rod
and mantle f should be removed from the burner by the thumb and forefinger,
as shewn. The rod end is then placed in the aperture d and rests in the socket e¹.
The shape of the cup c facilitates the entry of the rod into the aperture d, and the shape
of the lower cup e ensures its entry into the socket e¹; and inasmuch that the socket e¹
is directly below the aperture d, the mantle rod is held perfectly perpendicularly in
the tower. The conical shape of the tower enables the mantle to be placed over it
without fear of damage to the edge of the latter.
The tower is by preference provided with a ring g, by which it may be lifted with
the mantle upon it; but this is not essential.
The tower shewn in Figure 4 has a tube e, having a closed end which tube is
soldered in the aperture d in the cup c, and forms a socket for the mantle rod
end.
The tower shewn in Figure 5 is formed of glass, clay, earthenware, or wood, the
hole d being moulded or bored therein to form a socket for the mantle rod end.
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 support or holder for the mantle and mantle-rod of incandescent gas burners,
when the same are removed from their burner, in the form of a truncated cone,
having a broad base, and a cupped top into which the mantle rod end is inserted and
guided to an aperture therein, said rod being held perpendicularly by said aperture
and a coned socket, tube, or their equivalent, directly beneath the same, substantially
as herein described with reference to the drawing hereto annexed.
