Abstract
A security device is provided for coupling a rotational input force to an output shaft and includes a tubular housing with first and second ends and an internally-threaded bore extending therebetween. An externally-threaded screw member is threadably and reciprocably received in the housing bore and includes first and second ends. A slip clutch assembly is associated with the screw member second end and is adapted for drivingly innerconnecting the screw member and the output shaft. A socket assembly includes a clamp member with hingedly innerconnected jaws or sections which may be opened for placement over the screw member first end and closed for drivingly interconnecting the clamp member and the screw member. A collar nut may be placed over the clamp member for retaining it in its closed position.
Claims10
A device for transmitting an input rotational force to an output shaft, which device comprises:
- (a) a tubular housing including a bore with internal threads;
- (b) a screw member including:
- (1) a first end with a substantially conical or frusto-conical configuration;
- (2) a second end;
- (3) external threads threadably engaging said housing internal threads whereby said screw member is threadably and reciprocably mountable within said housing bore;
- and
- (b 4) an outwardly-open annular groove at its first end;
- (c) slip clutch means for interconnecting said screw member and said output shaft;
- and
- (d) socket means adapted for receiving a portion of said screw member first end and including a flange receivable in said groove.
