No. 27044.-15th December, 1909.-CHANDLER AND Co.,
LIMITED, of Auckland, in the Dominion of New Zealand, Con-
tractors (assignees of William V. D. Kelley, a citizen of the
United States, residing at Newark, in the County of Essex,
and State of New Jersey, United States of America). Im-
provements in or relating to gas-burners.

Extracts from Specification.-This invention relates to gas-
burners, and has for its objects to provide a thermostatically
actuated gas flashing burner.... We provide, in com-
bination with a steel ball or other magnetic valve disposed
within the gas-pillar, a movable exterior magnet which is moved
toward and from the valve by the contraction and expansion
of a thermostat which is disposed to be heated by the gas-flame,
the gas-flame being itself controlled by the opening or closing
of the magnetic valve. In the preferred embodiment of
the invention disclosed a spring normally tends to move
the magnet away from the valve, thereby permitting the
valve to close by gravity, which tendency of the spring is
resisted by the tension of the thermostat and the spring is
rendered effective to move the magnet away, and thereby to
permit the valve to close when the tension of the thermostat is
relieved by the heating effect of the flame.

[NOTE.-The above extracts from the specification are inserted in place
of the claims.]
