Abstract
670,804. Thermal switches. NAAMLOOZE VENNOOTSCHAP KONINKLIJKE METAAL-, WARENFABRIEKEN VOORHEEN, J. N., DAALDEROP & ZONEN. Sept. 23, 1949. [Feb. 4, 1949] No. 24462/49. Class 38 (v). A switch for controlling a water heater comprises a pair of bimetal reeds 3, 4, each carrying an armature 5, 6, co-operating with the poles 2a, 2b of a permanent anisotropic magnet 1. The reeds are fixed to a copper block 9 connected to one side of the supply, and are coupled by a rod 11 fixed to reed 4 and movable with lost motion in reed 3. On heating, the reeds deflect upwardly, until the armature 6 snaps away from, and the armature 5 towards the magnet 1, thereby opening contacts 12, 13. On a fall in temperature, the reeds restore to the position shown; The armature and poles have projecting co-operating pieces of silver to prevent sticking of the armatures. The Specification, as open to inspection under Sect. 91; comprises also a switch, Fig. 5 (Cancelled), having a number of bimetal strips 19 arranged with their ends in grooves in a fixed pillar.16 and a housing 18 rotatable on bending of the strips. The housing carries a member co-operating with a blade and magnet system similar to that described above. This subjectmatter does not appear in the Specification as accepted.
