Self-advancing teaching device

机译:自进式教学设备

摘要

A time teaching device which gives a numerical readout to teach a child the position of clock hands and is capable of advancing the clock hands every time the child activates the readout portion has a housing in which is located a clock face and typical hour and minute clock hands. Within the housing are two carrier members which have a plurality of indicia thereon which indicate numerically the position of the clock's hands. The carrier members are located in the housing beneath display openings. Interspaced between the display openings and the carriers is an interference member which normally interferes with viewing of the indicia on the carrier. Both the hands and the carriers are coordinated such that movement of the minute hand will move the hour hand and both of the carriers through appropriate increments. An operator member is located on the housing and when it is depressed into the housing the indicia corresponding to the positions of the hands is viewable. Upon release of the operator member the interference member interferes with viewing of the indicia while simultaneously the hands advance an increment of time and concurrently unseen to the child the indicia carriers move to advance the indicia to correspond to the new positions of the hands.
