Apparatus for Incinerating Incandescence Mantles.
I, CHARLES CLAMOND, of 15, Rue Picot, Paris, France, Engineer, do hereby
declare the nature of this invention to be as follows:
The mantles employed for incandescence lighting are made by saturating
combustible fabric with solution of certain metallic salts and after drying,
incinerating or burning off the combustible material so as to leave a skeleton
of earthy oxide in the form of a cap or mantle.
This invention relates to apparatus whereby the successive steps necessary for
incinerating are carried on so far automatically that only occasional action by
the attendant is required.
For this purpose, a vertically sliding rack geared to clockwork carries a down-
wardly inclined Bunsen burner having at its end a hook on which the mantle
to be incinerated is suspended.
The attendant turning a three way cock to a certain position pushes down
the rack thereby winding up the clockwork and opening a valve by which gas
is supplied to the Bunsen burner at the same time opening farther a valve which
was partially opened and thus increasing a kindling jet directed against the
Bunsen burner thereby lighting it, so that its flame plays on the top of the
mantle which burns gradually downwards.
The clockwork acting on the rack gradually raises the mantle and burner
until a valve is closed extinguishing the Bunsen flame.
The attendant turning the three way cock to another position again pushes
-down the rack and so ignites a strong Bunsen flame within the mantle which
plays on it as it is gradually raised by the clockwork. Finally, the attendant
turns the cock to a third position, brings another burner into position instead
of that just extinguished and again pushes down the rack.
The mantle is now subjected to a strong radiating Bunsen Hame inside and
a strong Bunsen flame on its top during its gradual ascent, the incineration being
thus completed.
Dated this g1st day of January 1899.

Apparatus for Incinerating Incandescence Mantles.
I, CHARLES CLAMOND, of 15, Rue Picot, Paris, France, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The mantles emploved for incandescence lighting are made by saturating

page_text: combustible fabric with solution of certain metallic salts and after drying,
incinerating or burning off the combustible material so as to leave a skeleton
of earthy oxide in the form of a cap or mantle.
This invention relates to apparatus whereby the successive steps necessary for
incinerating are carried on so far automatically that only occasional action by
the attendant is required.
For this purpose the apparatus is arranged as shewn in perspective in Figures 1
and 2 which represent the front and back respectively. A vertically sliding
rack a geared to clockwork in a case b carries a downwardly inclined Bunsen
burner having at its end a hook d on which the mantle m to be incinerated
is suspended. The attendant turning a three way cock e to a certain position
marked 1 pushes down the rack a thereby winding up the clockwork and opening
a valve f by which gas is supplied to the three way cock e and thence to the
Bunsen burner c at the same time opening farther another valve g which was
partially opened and thus increasing a kindling jet h directed against the
Bunsen burner c thereby lighting it so that its fame plays on the top of the
mantle m which burns gradually downwards. The clockwork acting on the
rack a gradually raises the mantle and burner and by acting on a tappet. closes
the valve thereby extinguishing the flame of the burner c, and the valve g
is nearly closed thus reducing the kindling jet.
The attendant turning the three way cock to the position marked 2 again
pushes down the rack and so ignites a strong Bunsen flame within the
imantle m which plays on it as it is gradually raised by the clockwork. Finally,
the attendant turns the cock to the position marked 3 and moving a slide n
brings another burner into position instead of which was just extinguished
by the ascent of the rack a, and he again pushes down the rack. The mantle m
is now subjected to a strong radiating Bunsen flame from burner inside and
a strong Bunsen flame from burner con its top during its gradual ascent, the
incineration being thus completed.
By maintaining the lighting flame h independently of the apparatus, the
valve and its connections with rack a may be dispensed with. Also instead
of two separate burners and and the slide on which they are fixed, a
single burner may be employed when the gas is supplied at considerable
pressure.
i
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Apparatus for incinerating incandescence mantles arranged and operating sub-
stantially as described, with reference to the drawings.
