To aZZ 107mm, t May cmibem:

i 13er it known that I, LESLIE valre f citizen ofthe Doiinen of Canaria, residing `at;iVanceuver, in the Provzieeofritish "Columbia, Canada, have .invented Lceriseni following `iS a epeeeaten.

Having new particularly described my invention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

1. Means for controlling the temperature of oil for combustion, said means comprising the combination with a steam ipe delivering steam to an oil heater, an a pipe delivering oil from the heater to the burner, of a valve in the steam pipe controlling the passage of steam therethrough7 achamber through which the oilto the burner passes, a container exposed to the oil in the chamber one side of which container is flexible, said chamber charged with a Huid having a high ratio of expansion under heat, means for connecting the flexible side of the conta incr to the valve of the steam pipe whereby outward movement of the fiexible side of the container will operate to close the valve, said connecting means comprising a stem on said valve, an extensionstem engaging Athe exible side of said container, an adj estable turn-buckle connection between said stems, a s ring for maintaining the engagement of aid extension stem with said flexible side of said container, means for ndjusting the tension of saidspring, said tension` adjusting means comprising a screw adapted to press against said spring, said screw being bored to permit passage of and having a passage for said extension stem, and means for supporting said valve and said container to maintain alinement of said stems.

2. A device of the class described, comprising the combination with a @cam pipe delivering steam to an oil heater and a pipe delivering oil from the heater to the burner, of a valve in the steam pipe controlling the passage of steam therethrough to the heater, an open ended chamber through which the oil pipe to the burner delivers from the heater, a container having asubstantially rigid side which closes the open end of -the chamber, and a flexible side externally exposed to the air, said container charged with a Huid having a high yratio of expansion, a stem the end of which rests on the flexible side of the container,- said stem endwise movable iii a screw threaded into a support secured to the container, a spring between the end of this screw and a washer secured on the end of the stem, .means y:for staying the valve of the steam pipe to the container, and means for adjustably connecting the end of the stem which rests on the container to the stem of the steam pipe valve that the valve may be opened when the fiexible side of the container is at the inner limit of its movement and will close as it expands outward from that position.

In testimony whereof I aixmy's'ignature.

LESLIE A. IVANY.
