Improvements in incandescent Light Burners.
I, MARTIN MEYER, of 105 Neuer Wall, Hamburg, in the Empire of Germany,.
Manufacturer, 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:-
The present invention relates to improvements in the arrangement and construc-.
tion of incandescent light burners having for its object to produce an especially
advantageous action of the mixture of air and gas on the exit of the same to the-
incandescent body.
In the accompanying drawings the new burner is illustrated in
Figure 1 in section, and in
Figure 2 in elevation.
Figure 3 is a plan showing the closing plate.
The mixing chamber in which the gas is mixed with the air is not contracted
towards the top, but continues and terminates in a cylindrical shape. The top-
plate of the burner consists of a conoidally shaped disc provided with perforations,
and the carrier or support of the incandescent body is adapted to be inserted into.
a tubular holder, the foot of which rests bridge-like in two sockets of the plate, so.
that the centre of the head or top plate remains clear.
The mixing chamber a of the burner consists of two tubes b and c slipped one
into the other, the outer one of which carries the burner gallery d, whilst the inner
tube b provided with suction inlet openings e for air has screwed into it the base
piece with a union or connection for the service gas pipe. Into the upper part
of the tube b there is further inserted a perforated plate y which serves to obviate
the disturbing noise of the upwardly passing gaseous mixture.
The closure at the top of the mixing chamber is constituted by a closing plate g
with the underlying sieve h. The plate itself is of conoidal shape so that it is
composed of a substantially vertical portion and of a substantially horizontal
portion. The slits or perforations from which the gaseous mixture is to flow, are
provided partly in the vertical, and partly in the horizontal portion, with the result
that the cone of gas is caused thereby to pass out of the plate in bell form having
a strong outward bulge.
In place of the central socket, two side sockets i and k are inserted in the plate,
for the purpose of receiving the forked foot of the carrier or support of the
incandescent body. The centre of the plate thus left clear is provided with star-
shaped apertures which allow of the exit of the gaseous mixture. A plate of this
shape may also be employed in burners of other types.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;-
1. In burners for incandescent lighting a burner plate g of conoidal form provided
with slits aud also two side sockets ik intended for the reception of the holder /
of the carrier or support of the incandescent body, and perforated also in the
centre.

page_text: 2. In combination with the burner plate referred to in Claim 1 a cylindrically
shaped mixing chamber composed of two tubes b, c, of which the inner tube is
provided with a perforated intermediate disc substantially as described.
