Abstract

107,949. Butler, J. April 17, 1917. Cases with internal horns.-The horn g of an enclosed-horn gramophone, instead of curving beneath the turntable a, is curved in the opposite direction, and has its mouth projecting beyond the front of the casing in order to allow a freer path for the sound and to enable the operator to adjust the sound-box d without impeding the sound. The space f may be utilized for storing records and accessories.
