COMPLETE SPECIFICATION.
Self-lighting Gas Burner.
I, RICHARD BEESE, of 13, Gluckstrasse, Dresden, Saxony, Germany, Architect,
do hereby declare the nature of my 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 a new and improved self-lighting gas burner of which
the following specification together with the accompanying drawing forming an
inseparable part thereof, is a full and clear description.
The drawing shows in vertical section a gas burner provided with my invention.
From this figure it will be seen that I employ a head A provided with a vertical
opening a, which in turn leads to a cut-away section b, the latter having the inner
surface of its walls screw threaded and adapted to receive the lower hollowed
end of a cap B, thereby forming a small chamber in the upper portion of said
head. Mounted in said head is a valve stem c, the upper end of which enters a
certain distance within a central vertical opening in cap B, while at its lower
end it passes downwardly into a registering vertical opening a formed in the
said head A. It will be thus understood that the said valve is susceptible of a
vertical reciprocating movement. Formed on said valve and near its end is
the valve cone c¹ which when raised tightly closes the cap-opening thus shutting
off any flow of gas therethrough.
A predetermined distance below said cone the valve stem is cut away forming
a cone which when said valve is depressed presses snugly against the walls of
opening a¹, closing thereby the same to any outflow of gas.
Formed in the said head A, and preferably at right angles to the aforesaid
openings, is a passage d, connecting at its outer end with a tube d, which latter
passing through a hollow rod e is by means of an opening 2 in connection
therewith. At a suitable position on said rod and connecting with the passage
therein is an elbow pipe f, having in its upper end a sponge of platinum g, or
other self-igniting mass as desired.
Fastened to said rod e is a depending compound plate h, preferably composed
of two or more materials differently expanding at a given heat for example iron
and copper; and engaging at its lower end a reciprocating plunger 7 moving in
a suitable guide and connected at its inner end by a nose m with a bellcrank
lever n and provided with a cutaway section k, allowing free play of the adjacent
end of said lever. The latter in turn is connected with and adapted to move the
double valve aforesaid e upwardly or downwardly. The lower end of the said
valve stem snugly fills the opening a so as to prevent any escape of gas there-
through, while on the outer end of the plunger 1 is fastened a button. 7.
The operation of my invention will be clearly understood from the foregoing
description and following statement. Desiring to ignite the flame, the cock is
opened, whence the gas passing into head A, through opening a into chamber b
is there checked as valve e is in its upper position, but a small and minimum
amount is allowed to pass through the upper portion, of opening a¹, through
passage dtube d', opening, rod through pipe f and upon the self igniting

page_text: mass g thereby producing a small flame; which in turn gives heat to the compound
plate h. The latter owing to the different expansion of its metal layers deviates
from its normal position thereby moving the plunger 7 whose nose m raises the
adjacent end of the bell crank lever n depressing valve stem c and opening valve c
and so allowing the gas to pass to the burner, where it is ignited by the small
flame. As valve stem e is now depressed the flow of the gas to the igniting mass g
is checked until the igniting flame is extinguished, but the plate / remains deviated
under action of the heat of the main flame. Should the main light flame be
extinguished through any cause while the cock is open, the same may be reignited
by pressing the button, whence a limited gas flow is again brought to act
upon the igniting mass. It will be seen that the danger heretofore existing
through the failure of action of a self igniting mass, thereby allowing a great
escape of gas, is now reduced by my invention to a minimum, while the simplicity
of construction insures the durability of the device.
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:-
I. A new and improved self igniting gas burner comprising a described_con-
struction in combination with a compound plate adapted through its heat-
occasioned deviations to operate the construction aforesaid, substantially as
described.
II. A new and improved self igniting gas burner, comprising a compound metal
plate having its parts adapted to differently expand under heat and in combination
with and actuating means for regulating and igniting the gas, substantially as
described.
III. In a new and improved self igniting gas burner, the combination of a
compound metal plate, a self igniting mass adjacent thereto, a burner in proximity
therewith and means actuated by said plate for alternately conducting a gas
current to said mass and burner, substantially as described.
IV. In a new and improved self igniting gas burner, the combination of a com-
pound metal plate, a head, a burner thereon, a self igniting mass adjacent to
said plate, a gas passage connecting said head and mass, a double valve adapted
to close said passage and simultaneously open said burner and means connecting
said plate and valve substantially as described.
V. In a new and improved self igniting gas burner, the combination of a head
provided with openings, a burner secured thereto, a double valve working in said
head, a self igniting mass, means for carrying a gas current from said head to
said mass, a compound metal plate adjacent to said mass and adapted through
the unequal expansion of its plates to deviate from its normal position a plunger
actuated by said deviation, a bell crank lever in connection with said plunger
and adapted to so operate said valve as to simultaneously open said burner and
close said current to said mass, substantially as described.
