Abstract

419,199. Adjusting wireless apparatus. IDEAL WERKE AKT.-GES. FUR DRAHTLOSE TELEPHONIE, Hohenschonhausen, Berlin. March 29, 1934, No. 9822. Convention date, March 29, 1933. [Class 37.] An abutment pin 6, secured to the actuating shaft 2, co-operates with abutments 7 on the driving disc 1 to limit the extent of its rotation. The abutments 7 may be stamped out of the disc 1. The shaft 2 is carried in a stirrup 3 and is actuated by means of a knob (not shown). The driving disc 1 is moved by means of a thread 8 which is wound on reels 4, 5 mounted on the shaft 2.
