Control circuitry for an advertising display

Claim 1

A control circuitry for coordinating the movement of a display with a sound recording, the circuitry comprising: a tape player operably driving a tape, said tape having secured thereto at a predetermined position, an activating means adaptable to complete an electrical circuit; a drive motor mechanically connected to a movable display, and electrically connected in series with a power source and a first relay switch; a normally-closed micro-switch connected in parallel with said first relay switch, and adaptable to open upon said movable display''s reaching a predetermined position; a second relay switch connected in series with a first relay, said first relay adapted to close said first relay switch upon the passing of current through said relay; a third relay switch connected in series with a second relay, said second relay adapted to close said second and third relay switches upon the passing of current through said relay; a switch connected in parallel with said third relay switch and adaptable to close upon the passing of said activating means therethrough; wherein, the drive motor, and hence the movable display, ceases to operate when said first micro-switch is opened, and resumes operation when the first relay switch is closed, said first relay switch being closed by the following progressive occurrences: a. said activating means on the tape passes through said switch and causes current to flow through said second relay; b. said second and third relay switches are closed by operation of said second relay; c. said first relay is activated, thereby causing said first relay switch to close.
