  • Patent number: 4220019
    Abstract: A shear clutch assembly for a rotatably driven power transmitting shaft and including a shear bolt which is sheared and causes a disconnect in the driving parts for the shaft. The assembly includes a flange rigidly fixed to the shaft and a rotatably driven member, for example, such as a sprocket rotatably mounted on the shaft and connected to the flange by the shear bolt. A reversing drive mechanism is carried by the driver or the driven member and when the power is transmitted in the normal or forward direction, the reversible drive connection is ineffective. However, when the shear bolt means has been severed and dislodged, power can be reversed and this causes the reverse drive connection to become effective for driving in the reverse direction.
