Abstract

741,927. Electromagnets. LE TOURNEAU, Inc., R. G. May 19, 1949 [June 15, 1948], No. 8518/52. Divided out of 741,921, [Group XXXIV]. Addition to 616,821. Class 35. In an electromagnetically-released multiple disc brake of the kind described in the parent Specification, the fixed and movable armatures respectively have identical laminated poles 20, 21 projecting normally from their respective bases. The poles'of the armatures comprise a number of concentric spirally wound bands 23 reinforced by retention rings 24, 25. The fixed armature bands 23 with their rings 24, 25 are welded to a wall 1 of a motor casing 2. The other armature bands 23 are similarly reinforced and welded to a floating braking disc 17. The poles are surrounded by energizing coils 22. Specification 741,928 also is referred to.
