Abstract

580,451. Electro magnets. DERUNGS, E. A. April 27,1944, No. 7908. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 27, 1944.] [Class 35] The plunger or the final core member of an electromagnet has its size reduced in steps towards the end co-operating with the member, or both members may be so reduced. In the form shown, the plunger 60 has reduced cylindrical and conical portions as shown, and the fixed core 61 is stepped to correspond. The winding is subdivided and some sub-sections may be used during a part only of the stroke, .and a single section will suffice to hold the core in the attracted position. The circuit changes may be made at contacts actuated by the rod 71 secured to core 60, or a single winding may be used with a variable series resistance. A modification with only two winding sections is described.
