Abstract
450,364. Adjusting wireless apparatus. HARMER, F. E., Flyingdales, Crabtree Hill, Collingham, and BELL, J. E., Moorfield Road, Ben Rhydding, both in Yorkshire. April 3, 1935, No. 10300. [Class 37] In a cord or belt drive for tuning adjustment, the cord passes one or more times completely around an indicator pulley and is anchored at both ends to the condenser pulley, the anchorage including a spring lever or arm for preventing slip. The cord 7 drives from the condenser pulley 6 to an indicator driving pulley 4, one end of the cord being anchored at 8 and the other end through a spring 9 having arms 9x, 9y. The pulley 6 is a disc with right-angled flange 6x, the cord passing freely through a hole 10 and being anchored to the arm 9x which is carried on a pin 11 in the disc portion of pulley 6. The tuning indicator may be incorporated in the face of a loudspeaker, the indicator pulley being located in the conical chamber behind the scale.
