Abstract

898,437. Automatic gramophones. HANSEN, H. C. Oct. 17, 1958 [Oct. 23, 1957], No. 4096/62. Divided out of 898,436. Addition to 852,061. Drawings to Specification. Class 40 (2). The description is identical to that of Specification 898,436. The claims, however, relate to the modification of the parent Specification whereby the switch in the motor circuit and the support for the stack of records comprise means to open said switch when the tone arm fails to engage the underside of a record on the said stack. Specifications 788,052, 788,054, 859,371, 859,372 and 889,661 also are referred to.
