Title: Improvements in sound recording and reproducing
IPC: G11B19/265
Filed: 1939-03-09
Abstract: 532,095. Sound recording and reproducing. PROCTOR CO., Inc., B. A. March 9, 1939, No. 7711. Convention date, July 8, 1938, [Class 40 (ii)] Relates to apparatus, particularly for use as a dictation machine, for recording on and reproducing from thin flexible discs. According to the invention, the disc 70 is driven by a pair of opposed feed wheels 102, 130 acting on opposite faces of the disc near the recording or reproducing point, the disc is keyed to a spindle 95 to which it transmits rotation, and this rotating spindle which is carried by a sliding frame 109a drives gearing whereby the spindle is gradually moved away from the recording or reproducing head. The disc 70 rests upon a curved partcylindrical support 88, being maintained in conformity with the support by walls 53 so that the disc is flexed when in use. The carriage is slidable on rods 51, 52 and provides bearings for a screw spindle 114 which can be engaged by a nut 124 on a lever 122, and which carries a wheel 116 gearing with a skew gear 117 on the spindle 95. Thus, as the record disc is driven, it causes, through rotation of the screw 114, a traversing movement of the carriage and of the disc itself past the stylus of the recording head 29 or reproducing head 30. A platen wheel 164, formed of alternate laminations of steel and rubber, engages the underside of the record disc just underneath the stylus as described and claimed in Specification 534,885. The stylus thus acts on the disc in a tensioned radial zone extending between the spindle 95 and the point of contact with the driving rollers, and by reason of the driving arrangement, the record disc passes the stylus at a substantially constant linear speed. The record disc, which is preferably made as described in Specification 534,886 of cellulose acetate, about 0.005 inch thick, having a slight coating of wax &c. as a lubricant, has at its centre a paper disc on which notes may be written. Through this disc and the record material itself, a hole is formed having teeth projecting inwardly to engage radial projections on the end of the spindle 96, whereby the drive is transmitted to the latter. A cap having a conical head 159 is removably fitted over the end of the spindle, and as the record carriage is traversed, the apex of the cone 159 moves in front of a scale 66 to indicate the position of the matter recorded. A microphone and loudspeaker circuit is provided as described and claimed in Specification 534,887, [Group XXXIX].
