Abstract

615,993. Phonograph apparatus. PHILCO PRODUCTS, Inc., (formerly PHILCO RADIO & TELEVISION CORPORATION). April 18, 1946, No. 12016. Convention date, April 18, 1945. [Class 40 (ii)] The Specification describes a phonograph apparatus of the type disclosed in Specifications 615,991 and 615,992, but includes an alternative construction, in which the lid 14 is replaced by a closure member 101, and the feeler arms 58, 59 are replaced by members 147, 148 mounted on slides 136, 137, Fig. 22, which are urged together by a spring 142, and which are connected to links 165, 167, 168 controlling the positions of the record stop pin 163 and to the pick-up arm stop lever 173. The opening of the closure member 101 draws forward a slide 126 which comes into contact with a lever 114 on the pickup arm spindle, which is rotated until another lever 113 on the said pick-up arm spindle comes into contact with a projection 175 on the pick-up arm stop lever 173, and thus sets the starting position for the stylus 115 on the record. Specification 601,974 also is referred to.
