Abstract

544,764. Sound recording apparatus. W.A.F. CO., Ltd., and ALLEN, H. H. March 12, 1941, No. 3345. [Class 40 (ii)] A rotatable member for receiving the shaving thread cut from a blank by a recording stylus is driven at a surface speed slightly less than the speed of production of the shaving to prevent breakage of thread by tension and to facilitate removal of thread from receiver. As shown; the invention is applied to a machine comprising an eccentric abutment 2 for a band 1 on which sound is recorded by a recording head 3. The shaving receiver is in the form of a hollow .drum 8 screwed to a sprocket wheel 6 driven round a fixed spindle 5 by engagement with the sprocket holes in the band 1. The head 3 is provided with a plate 9 to guide the shaving thread to the drum 8. In a disc machine, the drum is driven by a flange in frictional contact with the disc at a point near the cutting stylus.
