Abstract
Abstract A teaching machine apparatus is provided for teaching symbols such as numerals or letters along with their interrelationship, having a flashing light source in a casing. The casing has a segmented front having each segment having a transparent portion to allow the light from the light source to pass therethrough. Means are provided on the casing for attaching coded members over the transparent portions of the casing which coded members have openings located in predetermined locations. A symbol bearing member can be placed over each coded member which member also has a predetermined opening therein. When the correct symbol bearing member is placed over the correct coded member their opening will align, allowing the passage of light therethrough. The unit also provides for a light reflector so that a lamp can be used for a plurality of transparent openings and also for the transparent openings to be covered with transparent colored material for providing different colored flashing lights.

Total Claims: 7
Claim 1
Independent Claim
175 words
An educational game apparatus for teaching symbols such as numerals or letters and their inter-relationship comprising in combination: a. a casing; b. a light source located in said casing anD being connected to a power source, said light source having flashing means for flashing said light source; c. said casing having a plurality of segments on the exterior thereof for attaching a plurality of coded members thereto, each segment having a transparent portion adapted to transmit light from said light source therethrough; d. a plurality of first coded members for blocking out said transparent portions of said casing when placed thereover except for predetermined opening in each said coded member; and e. a plurality of second coded members having symbols thereon and predetermined openings therein, each said second coded member having a matching first coded member whereby when the coded member is placed over the matching first coded member their openings will align allowing light passing through said transparent portion to pass through said first and second coded members to produce a flashing light therethrough.
