Improvements in Gas Lighting Apparatus.
MOSES JAMES ADAMS, Engineer, Park Lane Sanitary Works, Leeds, 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: -
My improvement consists in an arrangement which enables me to abandon the
small bye pass light commonly employed with the incandescent gas mantles now
largely used It has been found desirable to convey a flame to the mantle before
turning on the gas to the same and thus to prevent the shattering of the mantle
which hequently results if a light is applied to cause ignition after turning on gas
to the mantle Now instead of the bye pass light which is continually burning,
I provide a small gas jet which is so fixed that its flame reaches upwards
sufficiently far to ignite the gas when the same is turned on to the mantle, and
instead of leaving this jet continually burning, I place it in such a position that
it is lighted as an ordinary gas burner each time, and I so aange the cock
through which the gas is supplied that it not only feeds the jet, but also the
gas supply for the mantle. Then on turning this cock a certain distance the
small jet may be lighted, its flame reaching as aforesaid upwards towards the
mantle Still turning the cock a supply of gas passes to the mantle itself where
ignition is caused by the small jet and still turning the cock the gas is cut off
fiom the jet and the mantle receives the entire supply. Reference to the accom-
panying diawing will make my invention clear Though I shew this small gas
jet as external and prefer it so, yet it is evident that it may be placed to give
its light within the mantle and all inside the case or body of the apparatus, and
that it will answer equally well so, but it is imperative that facility be given for
lighting the apparatus by match or taper in a simple manner each time of use.
A is the stalk through which gas is supplied to the cock H This cock has a lever
or handle B shewn in different positions, also at B and B there is a port or
opening H through this cock and as shewn it is evident that the gas supply is
shut off At C is a small tube to supply the jet D and when the lever reaches
position B gas will feed to this small tube and the net 1 may be ignited, its flame
rising upwards towards mantle F On turning the lever to B gas will pass
upwards to the mantle through G and a quiet ignition will result therein, and the
supply to tube C will be cut off E is the gallery for chimney
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 18:
1st The use of an external or internal et m flame placed in such a manner that
the said jet or flame is easily lighted each time of use and causes ignition of gas
supplied to a mantle, the said gas being fed to the mantle after the jet is lighted
in combination with a gas cock which shall feed both the jet and the mantle.

page_text: 2nd. The use in combination of a gas jet lighted each time of use and gas
mantle for the purposes described and as described.
31d The use of a gas cock which shall feed a small jet as described for ignition
each tune of use, and shall also feed gas to a mantle where it shall be ignited by
the said jet
4th. The use of the jet whether placed externally or internally so long as it
shall effect the object named in supplying light from match or other light each
time of use to ignite gas fed to a mantle.
5th The use of the arrangement shewn and described or its equivalent, though
differing in conformity, substantially the same.
