Abstract

1,250,360. Spinning top game. M. J. PEARS and B. W. SIMS. 6 April, 1970 [4 Jan., 1969], No. 683/69. Heading A6S. [Also in Division B6] A line is marked on a surface by a spinning top by means of a writing tip 4 at the tip of the top on a surface which is treated or adapted to be marked as the tip bears against it. The top may be weighted off centre to affect the course of the top when it is spinning. The top includes a disc 2 mounted on a shaft 1 having the marking tip. The disc may be supported on ball bearings so as to be rotatable about the shaft 1. The tip may be cruciform to produce a regular pattern.
