Abstract

The device consists of two identical discs, one of which is shown in the drawing mounted on a common shaft. Each disc is made of insulating material 3. Each has on it a number of strips of conducting material 2, dividing it into ten segments and four circular tracks. Each disc has four brushes in contact with it, one brush for each circular track. The strips 2 are identically arranged on each disc.

Electromechanical Delay Device

The device consists of two identical discs, one of which is shown in the drawing mounted on a common shaft. Each disc is made of insulating material 3. Each has on it a number of strips of conducting material 2, dividing it into ten segments and four circular tracks. Each disc has four brushes in contact with it, one brush for each circular track. The strips 2 are identically arranged on each disc.

The four brushes of each disc are stationary, are read simultaneously and are initially in contact with identical patterns. To set up the delay required, one disc is turned manually relative to the other disc through an angle corresponding to the delay. The sets of brushes are then in contact with different patterns. The discs are then rotated together by means of the common shaft.

The delay period begins when the pattern of the strips 2 on the one disc in contact with the brushes of that disc is electrically read and stored. The delay period ends when the pattern of the strips on the other disc in contact with the brushes of that other disc is the same as the stored pattern.
