Abstract

571,382. Reciprocating motors. PLESSEY CO., Ltd. (Mallory & Co., Inc., P. R.). Dec. 28, 1943, No. 21759. [Class 35] [Also in Groups XXII and XXXVII] The T -shaped electromagnet core 15 of a vibrator is welded, by welding projections 27, to the transverse portion 14 of the frame 13 after receiving its winding 16. The winding is wound directly on the core 15 between insulating spacers 17, 18 which are slipped onto the core 15 and turned through a right angle.
