Abstract
517,376. Telegraphones. WALLIS, L. S. June 25, 1938, No. 18872. Addition'to 482,536. [Class 40 ii)] Relates to means for winding and feeding magnetic sound record wires of the kind described in the parent Specification. According to the invention, the wire ' 13 is drawn through a sound recording or reproducing device 14 on to the tapered lower part of a rotating drum 10 which may or may not have the step or abrupt change in diameter shown at 10a above the part on to which the wire feeds, and the wire is taken off by a tensioning pulley 15 which leads the wire on to an auxiliary drum 17 around which the wire passes in the opposite direction to that in which it is wound round the main drum 10. As shown, the tensioning pulley 15 is carried. by an arm 16 rotatably mounted on the spindle of the main and auxiliary drums 10, 17 which are co-axial, a friction pad is inserted between the arm 16 and the drum 10, and another friction pad 18 between the drum 17 and the spindle 11 about which the drums rotate. A pulley 20 returns the wire from the drum 17 to the recording or reproducing device 14.
