Abstract

862,004. Automatic gramophones. HANSEN, H. C. March 4, 1957 [March 5, 1956], No. 6842/56. Drawings to Specification. Class 40 (2). The Specification describes and claims a phonograph record-changer having a centrepost as described in Specifications 845,182 and 857,571, but modifications are also shown, particularly in the geometrical shapes of the record supporting prongs and the associated cam members which operate them with the objects of improved strength and reduction in the forces required to operate the centre-post mechanism.
