Mechanism consists of two friction disks mounted on the drive shaft so arranged that, dependent upon the position of the shaft, only one disk makes contact with the friction wheel. When the handle is pushed in, the shift is moved bringing the other disk into contact with the wheel, thus reversing the rotation of the output indicator. Slight speed variation of the output indicator is possible by positioning the friction wheel. Price: $73.17
Drive illustrates the action of the friction ratchet coupled with the crank-and-rocker drive. The output indicator will rotate only when the rocker arm is moving in one direction due to the action of the friction ratchet. Center distance between the shafts and the length of the floating link are adjustable to facilitate the analysis of this drive. Price: $47.04
