Abstract

To simplify control, a detent acts both as a detent and dog clutch. The device comprises a drive shaft, the latter being provided with an end slot for receiving a drive key. This is spring-urged radially outward to engage a tapered rectangular hole. Such is located in the wall of a driven sleeve coaxially mounted over the drive shaft. A detent is guided for movement into the tapered rectangular hole in the wall of the driven sleeve and against the drive key. With the detent actuated, its tip provides a surface on which the key rides as it passes the rectangular opening when the drive shaft is rotated. Due to the tapered shape of the detent and the rectangular opening of the driven sleeve, accurate detenting of the latter is achieved.

Mechanical Clutch and Detent

To simplify control, a detent acts both as a detent and dog clutch. The device comprises a drive shaft, the latter being provided with an end slot for receiving a drive key. This is spring-urged radially outward to engage a tapered rectangular hole. Such is located in the wall of a driven sleeve coaxially mounted over the drive shaft. A detent is guided for movement into the tapered rectangular hole in the wall of the driven sleeve and against the drive key. With the detent actuated, its tip provides a surface on which the key rides as it passes the rectangular opening when the drive shaft is rotated. Due to the tapered shape of the detent and the rectangular opening of the driven sleeve, accurate detenting of the latter is achieved. When the detent is retracted, the key is spring-urged into the rectangular opening providing a positive coupling of the driven sleeve with the drive shaft. Preferably, the drive shaft is stationary while the detent is actuated or retracted.
