Abstract

522,508. Reciprocating motors. STEVENS, A. H. (Sparks-Withington Co.). March 17, 1939, No. 8554. [Class 35] A reciprocating motor with a circuit breaker actuated by the armature has a winding consisting of a strip metal wound about a core to which one end of the strip is connected, the conductor being insulated except one or more of the innermost turns with strip insulating material. In the form shown the inner end of the copper strip is secured to the core 10 for which the inner and uninsulated turns form a damping winding, the remaining turns being separated by strip insulation. The outer end of the copper strip 37 is secured to the circuit breaker 26, 27 actuated by the stud 13 secured to the armature 17 and the diaphragm 3 of a warning signal. A flat spring 19 is provided as a guide for the armature.
