Abstract

This device relates to a method for controlling the delivery rate of toner from a supply bin to a mixing unit. This device employs three closely wound springs 1, 2 and 3 disposed as shown above. Each spring is supported by a thin flat strip 4 so dimensioned as to enable the springs to move freely thereover. One end 5 of the strip 4 is anchored in block 6. One end of each of the springs grips the serrated portion 7 of the strip 4. The other end of each of the springs is anchored in a sliding member 8 which is free to move in sleeve 9 mounted in the wall of supply bin 10.

This device relates to a method for controlling the delivery rate of toner from a supply bin to a mixing unit. This device employs three closely wound springs 1, 2 and 3 disposed as shown above. Each spring is supported by a thin flat strip 4 so dimensioned as to enable the springs to move freely thereover. One end 5 of the strip 4 is anchored in block 6. One end of each of the springs grips the serrated portion 7 of the strip 4. The other end of each of the springs is anchored in a sliding member 8 which is free to move in sleeve 9 mounted in the wall of supply bin 10.

The basic concept is to open and ~lose the close wound springs 1, 2 and 3 to permit the toner material to flow through by gravity.
