Complete Specification Left, 1st Feb., 1897-Accepted, 10th Apr., 1897
I, LOUIS DENAYROUZE, of 70 Boulevard Victor-Hugo, Neuilly (Seine) France,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to burners in which the combustion of an intimate mixture
gas
and air is employed to heat a mantle or other suitable appliance giving light
by incandescence.
of
The object of my invention is a simple application of heat, either that of the
products of combustion or that of a separate flame to work apparatus for feeding
the air and thoroughly mixing it with the gas. For this purpose when the heat of
the combustion gases is to be utilised I mount at the side of the lamp a vertical
spindle on the top of which is fixed a wheel having inclined blades extending over
the lamp chimney.
In a casing below the burner there is fixed on this spindle a wheel with fan
blades. The ascending products of combustion cause the upper wheel to revolve
and this drives the lower wheel which draws in air and thoroughly mixes it with
gas also entering the casing, and propels the mixture in a gentle current to the
burner. When a separate flame is used, I mount under the burner a horizontal
spindle carrying at its one end within a casing a wheel with blades of spiral form,
and at its other end, within a separate casing, a wheel with fan blades. A small
light, which may be fed from the gas pipe or may be that of a separate lamp burns
under the casing first mentioned, being in such a position that the ascending
products of combustion acting on the spiral blades cause the wheel to revolve, and
the fan wheel is thus driven drawing in air and mixing it thoroughly with the gas
to supply the incandescence burner.

I, LOUIS DENAYROUZE, of 70 Boulevard Victor-Hugo, Neuilly (Seine) France,
Engineer, 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:-
of
My invention relates to burners in which the combustion of an intimate mixture
Igas and air is employed to heat a mantle or other suitable appliance giving light
by incandescence.
The object of my invention is a simple application of heat, either that of the
products of combustion or that of a separate flame to work apparatus for feeding
the air and thoroughly mixing it with the gas.

page_text: For this purpose I provide an incandescence lamp with apparatus which I shall
describe with reference to the accompanying drawings.
Figures 1 and 2 are vertical sections, on planes at right angles to each other of
one form of apparatus according to my invention in which the movement is obtained
from a flame separate from that of the burner.
Figure 3 is a vertical section partly in elevation of apparatus in which the
movement is obtained from the heat of the burner flame.
Referring first to Figures 1 and 2, at the side of the lower part of the lamp
I mount on a horizontal axis e a wheel T having curved blades and under this
wheel a little at one side I provide a small gas jet v, the ascending products of
combustion from which cause the wheel T to revolve. In order to regulate its
speed, a light spring r carrying at its end a rubber, is attached to one of the blades
so as to bear with certain friction on the interior of the wheel case, and act as a
brake. On the axis c is fixed the fan P by which the gas and air supplying the
flame are thoroughly mixed.
According to the modification shewn in Figure 3, the axis c is vertical and has
at its upper end the wheel T made with inclined blades on which act the products
of combustion ascending from the lamp flame, causing the wheel T and the mixing
fan P to revolve.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In combination with an incandescence gas burner and its fan for mixing the
gas and air, a wheel on the axis of the fan caused to revolve by the action on its
curved blades of the products of combustion of a small gas flame, substantially as
described.
2. In combination with an incandescence gas burner and its fan for mixing the
gas and air a wheel on the axis of the fan caused to revolve by the action on its
inclined blades, of the products of combustion, from the burner flame, substantially
as described.
