Abstract

750,900. Electric control systems. MILWAUKEE GAS SPECIALTY C. Jan. 7, 1953 [Jan. 8, 1952; Jan. 8, 1952; Jan. 16, 1952; May 31, 1952], No. 526/53. Class 40(1) [Also in Group XXXVII] A temperature-sensitive device controlling the fuel supply to a burner by varying the resistance of the control circuit, comprises a fluid-filled bellows 106 mounted on a base plate 107 and carrying on its movable end 108 a contact 123 co-operating with a fixed contact stem 111, temperature variations producing changes in the contact pressure to vary the circuit resistance. A leaf spring 120 fixed at 121 carries a factory adjustment screw 124, the free end 119 of the spring co-operating with an annular cam surface 118 in a temperature adjusting knot 116. In Fig. 13 (not shown) the bellows is connected by a capillary tube to a fluid-containing bulb subjected to the temperature changes.
