Abstract

421,639. Gramophones. COLLARO, C., 84, Portsdown Road, Maida Hill, and COLLARO, Ltd., Culmore Road, Peckham, both in London. June 15, 1933, No. 28493/34. Divided out of 421,575. [Class 40 (ii)] Relates to gramophones in which the mechanism is arranged in a casing that may be kept closed throughout the playing of a series of records. According to the invention, the casing is formed with an opening in one side, through which the pick-up or sound-box may be swung outwardly, and a controlling mechanism is arranged to engage the pick-up or sound-box arm for bringing it automatically to the position for starting playing, but is adapted to allow the arm to be swung outwardly by hand to enable the needle to be changed when necessary. The invention is particularly applicable to a machine of the kind described in Specification 406,311, which provides a unit that may form a stand for a wireless set in conjunction with which it is used. The Figure shows the casing of a machine embodying the invention, of which a characteristic feature is the lateral opening 3 through which the pick-up arm may be swung, the opening being adapted to be closed by a hinged flap. A slot 2 is provided in the front wall of the casing, through which the records are inserted and automatically ejected after playing, as described in Specifications 406,311, 421,575, and 421,638. The mechanism of the apparatus described and shown in the Specification is the same as that described in Specifications 421,575 and 421,638.
