Abstract

565,252. Temperature-responsive elements. GOULSTONE, O. H. Jan. 2,1943. No. 8862. [Class 64 (ii)] [Also in Group XXXVII] An S shaped blade spring g engages recesses in the movable contact a and fixed support c of the contact-blade b, and is engaged at h by deflecting means such as the U -shaped bimetal element i pivoted at j and adjusted by screw k. A right-hand thrust on the spring g causes the contact. a to snap over against a back stop of further contact n. Alternatively, a fixed member-may bear on the spring and produce its sinuous form, the thermostat or other deflecting means acting on one of the curves.
