We, VINCENT JARRE and ELIE JOSEPH USANNAZ, Engineers, both of 137 Avenue
Parmentier, Paris, in the Republic of France, do hereby declare the nature of this
invention to be as follows:-
Our Invention relates to burners and gas taps therefor more especially intended for
use in burning acetylene gas but applicable also for burning ordinary or other
illuminating gas, and the principal object of the invention is to provide a burner
which is especially suitable for burning rich gas such as acetylene gas as although the
orifices through which the gas issues are very small they can be very easily cleaned
by removing a socket or cap arranged as hereinafter described. We thus avoid the
inconvenience which is met with in other burners with small orifices which are very
liable to become clogged and which it is often almost impossible to clear without
causing distortions of and injury to the burner.
The burner is composed of a central part screwed or otherwise affixed to the end of
the gas supply pipe. The said central part is covered by a socket or cap which may
be secured by a screw-nut to the central part. These two pieces together constitute
the burner proper. The central part is hollow and communicates with the gas supply
pipe and has near its end a recess forming an annular conduit, when the socket or cap
is in place. An orifice conducts the gas from the interior of the central part into the
annular recess. The central part is also provided with a recess or with recesses
extending from the annular recess to the top for the passage of the gas to the point
or points of ignition.
The section of these recesses may be straight or angular, or of any other suitable
form and their area may be extended either in breadth or in depth. When the
central part is covered by the socket or cap, only small orifices are presented for the
escape of the gas. The gas passes through the gas supply pipe and tap and through
the orifice into the annular space and through outlet passages formed by the recesses
leading therefrom and by the socket or cap covering the said recesses.
To clean the orifices, the screw-nut is unscrewed and the socket or cap is removed
when the inner surface of the recesses being completely exposed, the cleaning can be
very readily effected. The tap is constructed so as to prevent leakage of gas. It is
composed of a conical plug turning in a lining of cork or like material provided in the
body of the tap. A screw socket by pressing on rings slipped on to the stem of the
valve ensures gas tight closure between the plug and the lining.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we declare that what we
claim is :-
1. In gas burners, a central part such as A having on its periphery a recess or
recesses in communication with the gas supply, and a removeable socket or cap
covering the said recess or recesses so as to allow of ready cleaning by removing the
said socket or cap, substantially as hereinbefore explained.
2. A gas burner consisting of a hollow central part such as A, with an annular recess
around it communicating by an orifice with the interior, and another recess or other
recesses extending up from the said annular recess, all the recesses being covered by a
socket or cap, such as c, capable of being removed, substantially as and for the
purpose herein before described.
3. A gas burner consisting of a hollow central part such as A with an annular recess
around it communicating by an orifice with the interior, and another recess or other
recesses extending up from the said annular recess, all the recesses being covered by a
socket or cap, such as c, capable of being removed, and a gas tap packed with cork
or the like, and with discs and a screw cap.for ensuring gas-tightness, substantially as
hereinbefore described.
