Abstract

524,804. Sharpening gramophone needles. IMHOF, A. G. Jan. 6, 1939, No. 552. [Class 60] Gramophone needles are held for repointing in a chuck D rotated by a rubber tyre L running on a roughened surface as a block C is traversed by a handle O along a rail E. The needle is pointed by a strip of cardboard &c. coated with abrasive and retained on the base of the device by lugs H. The proportions are such that pressure on the handle to swivel the tyre onto the driving surface also applies the necessary pressure between the needle and the abrasive strip.
