Abstract
227,904. Roberts, S. C. H. Oct. 22, 1923. Cases with internal horns; tonearm joints.-In a gramophone or the like in which the tone-arm branches off to separate horns above and below the record, the upper and lower horns communicate directly with the opposite ends of a vertical standard in which the tone-arm is pivotally supported. The invention is shown as applied to a machine having a horn 5 formed in the lid of the casing, as described in Specification 185,455, a horn 38 being provided in addition in a space below the turntable. The inlet openings of both horns register with the ends of a vertical standard 10 mounted on a plate 21 in the casing, and forming bearings for a T-piece 14 at the end of the tone-arm, as shown in Fig. 4. The inlet orifice 6 of the horn in the lid moves awav from the tone-arm outlet when the lid is opened, Fig. 1, and forms a tight joint with a rubber &c. ring 30 on the top of the standard 10 when the lid is closed. Both horns are preferably provided at their mouths with adjustable flaps 42, 23. Two or more horns may be provided above as well as below the record, each being connected by a branch pipe to the tone-arm.
