Abstract
A transmission device has input and output members interconnected by two transmission members. One of the transmission members has only Restricted movement in either direction, and relative movement between the transmission members is necessary for movement of the output member. A pair of brakes are operable by movement of said one transmission member to prevent movement of the other transmission member in respective opposite directions. The arrangement is such that operation of the brakes by one transmission member in response to movement of the input member does not prevent movement of the other transmission member, whereas operation of the brakes in response to movement of the output member arrests movements of the other transmission member.
