Abstract
A spelling machine includes a housing having a row of drums on a shaft and is provided with a series of evenly spaced letters on the drums viewable through a row of holes in the housing. A row of slides in the forward portion of the machine has lugs and stop members respectively on opposite end portions. A series of cards each having a different picture thereon is inserted into the machine. Each card is provided with a row of holes spaced predetermined distances from an edge of the card which is parallel to the shaft when the card is inserted in the machine. The holes respectively receive the lugs on the slides and are operable to move the slides and stops thereon toward the drums various distances corresponding to letters respectively on the drums when the drums are rotated from starting position in one direction. Rotation limiting elements on the drums engage with the stop members on the slides to dispose the drums with a letter on each drum showing through each of the holes in the housing and spelling the name of the object on the card. The housing includes structure to rotate the drums in the opposite direction back to the starting position.
