erature con- My invention relates'to tem y to thermotrolled devices and particular static material.
The objgctof my invention is to provide a metallic thermostat that shall operate properly over a relatively large temperature range, that. hall resist oxidation at h1gh temperatures, and that shall retain its operating characteristics even after a long con- 10 tinued use. 0
In practicing my invention, I provide a thermostat com rising metallic elements one of. which ismo ybdenum and the other of which is an alloy of chromium and cobalt l and which may also contain iron. An 0x1- dation-resistant coating of electrolytic chr0- mium is also provided over the outer entire surface of the thermostatic member.
In the-single figure of the accompanymfi drawing, I have illustrated, in long1tu 1 n section, the device embodying my invent on. The use of two metals, intimately umted over their entire adjacent and abutting surfaces, for obtaining a movement of one part thereof relatively to the other part under I temperature changes is well known, partlcularly for relatively low temperatures. When the problem is presented of roviding such a metallic thermostat for re atively high temperatures and. for relatively large temperature changes, it is one that is not easily solved, particularly by. the use of the metals heretofore employed, as these metals lose their original characteristics and also 36 oxidize at the relatively high tem eratures. These temperatures may be as big as 600 "C. oreve'n up to 800 C. I have found that molybdenum has a relatively high elastic limit, even-when heated to the hereinbefore 40 mentioned high temperatures, and I have also found that certain alloys of chromium and cobalthave relatively high strength at the high temperatures hereinbefore together with a relatively great resistance to j Molybdenum has a mean or average temperature expansivity of approximately 6X 10" between the limits of 0 'while an alloyof chromium and. cobalt containing ap roximately of cobalt (1 approximate y 20% of chromium has a mea r v average temperature expansivity of'approximately 17x10" between 0 C. and800 and is a ductile alloy.
I have foundthat an alloy containing mentioned,

cobalt, 22% of cm slightly higher could also be a o when heated in the must, therefore, be protected against such oxidizing action w ploy the device at tem eratures above limit.

I have hereinbeforementioned the possibility of the use of and such all of cobalt, 30% to 10% the balance being1 alloy, 10% to 30% mium, small quantities of a cobalt-chromium-iron oys may contain m of chromostlyiron, and er materials, menthe tioned above in connection with the cobalt chromium alloys, forgeable ingots.

Since various modifications and changes may be made Without departing from the spirit-and scope of the invention. I desire that only such limitations shall be placed thereon as are imposed by' the prior art.
I claim as my invention:
1. A heat-responsive device comprising a plurality of'metallic elements, one of said elements being a ductile chromium-cobalt al- 10y and the other element being molybdenum.
2. A heat-responsive device comprising a plurality 'of metallic elements, one ofsaid elements being a ductile chromium-cobalt alloy, the other element being molybdenum, and an oxidation-resistant coating of chromium on both said elements.
