ABSTRACT:
A portable score keeping device for use in strenuous games such as tennis, racket ball, Ping-Pong, etc., suitable for attachment to the wrist or the waist of the player, is constructed so that successive points and games as they are scored may be fed into the device and totals shown through windows visible to the player. A novel ratchet and pawl arrangement facilitates the feeding in of data to the device and prevents errors which might be caused by improper registering or accidental movement of the mechanism during play.
