Abstract

576,596. Recording instruments. FIDELITY ENGINEERING CO., Ltd., BUDDEN, R. G., and CROWTHER, F. K. Jan. 15, 1944, No. 811. [Class 106 (iv)] In an instrument employing recording means comprising a flexible sheet or film pressed by the recording stylus against a surface to which it is capable of adhering visibly, the stylus is intermittently actuated by power operated means at predetermined intervals. A rotating glass disc 1 is provided on the underside with a wax coating against which rests a dark coloured paper disc 4. A recording stylus 7 is intermittently actuated by a striker 8 operated by a prime mover 2 to press the paper disc againet the wax to produce a visible record. A stylus actuated by an intermittently actuated striker may be replaced by a constantly vibrating stylus. A stripper arranged between the discs, and in front of the stylus in the direction of rotation of the discs, separates them to obliterate the record. A modification employs an opaque base coated with wax and covered by a transparent flexible sheet. A drum form may be used instead of a disc.
