Abstract: A carriage lock selectively enables and prevents a mobile carriage from moving along rails embedded in a building floor. The mobile carriage includes a shaft on which are rotatably mounted a driver sprocket, a hub, and a handwheel. The hub mates with the driver sprocket. A chain and sprocket mechanism connects the driver sprocket with the carriage wheels such that rotation of the handwheel and hub causes the carriage to move along the rails. A locking knob is loosely captured between the hub and handwheel for being manually rotated through a predetermined angle relative to the hub and handwheel. A pin is translatable within the hub parallel to the shaft longitudinal axis. The pin has a head that is received within a selected one of two angularly spaced depressions in a cam formed on the locking knob. The depressions are also spaced apart in the direction of the shaft longitudinal axis.

Abstract: A mobile carriage is movable along rails by manual rotation of a handwheel. The mobile carriage comprises a visual indicator that instantly informs a person of the locked or unlocked status of the mobile carriage. The visual indicator comprises at least one ridge on the handwheel and another ridge on a locking knob. The locking knob is loosely captured between the handwheel and a hub for selective rotation relative thereto between first and second end positions. The locking knob has a cam that slides a pin within the hub between first and second positions whereat the pin disengages and engages a stationary lock plate. When the locking knob is manually rotated to the first end position thereof, the pin disengages from the lock plate to enable handwheel rotation and carriage movement. Manually rotating the locking knob to the second end position thereof causes the pin to engage the lock plate and prevent handwheel rotation and carriage movement.

Abstract: A flush-mountable, key-controlled, handle-operated door lock is provided with an automatic self-locking linkage for permitting the handle to move once, but only once, out of a nested position after a key control has been operated to "cock" the linkage. Once the linkage has been cocked, the handle can be moved one time out of and returned to its nested position, whereafter the linkage operates to retain the handle in its nested position until the key control is again operated to cock the linkage. The automatic latching linkage includes a housing assembly, a pair of cams, and a pair of springs. A feature of the automatic latching linkage is that its several components can be assembled easily on an existing, in-service lock to provide the existing lock with a one-trip automatic locking capability. The latching linkage components are assembled by installing the components one at a time in an essentially stacked arrangement, one atop the other.

Abstract: A lever arm lock for a conventional quick-release hub assembly includes a cover mountable to a first skewer rod end nut supporting a quick-release lever arm. The cover is secured to the end nut with a locking mechanism (combination, magnetic, key, etc.) and maintains the lever arm in a locked position making it impossible to remove the hub. A second skewer rod end nut opposite the first end nut is formed with a substantially smooth outer surface that is continuously inclined with respect to the axle. This surface configuration prevents removal of the locked hub assembly by turning the second end nut with a pliers or other tool. The lever arm lock also prevents the hub from being jarred loose on impact with curbs, rocks, etc. The end nut assemblies have extensions which abut the frame thereby preventing loosening thereof for unauthorized removal.

Abstract: A locking unit for immobilizing road vehicles to prevent their unauthorized removal comprises a sealed body which houses a movable locking member projecting from the housing and adapted for connection with a brake or clutch operating foot pedal or hand lever or with the control valve of an air-powered parking brake system. The sealed body also houses a key-released lock of the rotary barrel type having its plunger movable into locking engagement with the locking member manually without use of the key. The locking member may be a ratchet wheel engageable by a pawl which is pushed into engagement by the lock plunger acting on a spring. Further springs ensure the pawl being held clear of the wheel when the lock plunger is withdrawn. A modified form of the unit has a fixed jaw and a movable jaw by which the unit can be clamped around the stem of the draw-pin of a trailer vehicle and locked without using the key, thereby to prevent the hitch of a tractor from being coupled thereto.
