Abstract

185,935. Japy, A. P. Aug. 16, 1921. Addition to 151,870. Dials and scales; index hands and pointers.- In apparatus for indicating statistics described in the parent Specification, consisting of an outer dial 1 supported in a frame 3 and an inner dial 5 supported on a button 7 so as to be rotated through a slit in the dial 1, the button 7 is supported by the outer dial 1 which is fixed in a spiral groove b thereon. The dial 5 is held in a second spiral groove 6. In a modification, the spiral groove b may be dispensed with by making the button 7 fit exactly in the circular opening in the dial 1. Relative rotation of the two dials is arranged to give a warning noise by means of a projection on the dial 1, or a protection g on a spring blade h attached to the dial 1, contacting with a series of teeth f on the back of the dial 5.
