Cable Storage Reel

the reel is for storing and retracting a length of cable. such, e.g., is a multiple conductor cable used to interconnect a microphone and control hand set 10 to a dictating machine.

The reel has circular base plate 11 and divider member 12, mounted for rotation about pin 13. Member 12 effectively divides the reel into three annular and concentric areas 14, 15 and 16. Nestingly received in area 14 is coil spring
17. Outer portion 18 of a cable is tightly wound in one rotational direction in area
16. Inner portion 20 of the cable is loosely wound in the same rotational direction in area 17. The cable is clamped to the reel at point 21, while inner end 22 of the cable is rigidly held and directly connected to the dictating machine.

When the operator pulls on hand set 10, the reel rotates and outer portion 18 of the cable unwinds. At the same time, inner portion 20 of the cable is wound about the housing for the coil spring. Inner end 22 of the cable does not move and commutator structure is not required. Coil spring 17 is wound during unreeling and operates to automatically retract the cable. Off-center cam 23 releasably holds the cable in the extended position.
