Abstract

17,637. Chisholm, C. L. Aug. 31. Phonographs. - Relates to a pointer for indicating the speed, the key, and the tempo or metronome tempo in which a record is being reproduced. By means of a screw acting on the governor and this pointer, the speed or key can be adjusted. It is stated to be of use for teaching music, and particularly absolute pitch. A preliminary adjustment of the screw 16 or 17 is first necessary, a tuning- fork being used, which enables either the scale or the pointer to be moved relatively without affecting the governor. The instrument may be adapted for use with disk or cylinder machines. Several modifications in the shape and arrangement of the indicator are given, of which two are shown in Figs. 1 and 9.
