Abstract: A vertical edge of a sliding door has a cavity forming a housing for a bolt. One or two angle-shaped latch leaves are located at a side or opposite sides of the bolt, each leaf being pivotally mounted in the housing for swinging about an axis generally aligned with such door vertical edge. Outward sliding of the bolt swings the latch leaf or leaves outward to lock flanges on the leaf or leaves in a catch carried by a frame.

Abstract: A sliding door is provided which is suitable for use as a heavy door for vaults in banks. The door is provided at its bottom with driving wheels adapted to be rotated manually by means of a handle, through a suitable power transmitting means, thereby to move the door along a rail. The power transmitting means may incorporate a suitable reduction means so that the door may be moved with a reduced force and, accordingly, at a lower speed. Means are provided for locking the door in the closed state.

Abstract: A lock for windows or other structures having relatively movable parts and having a lock casing and a keeper separable therefrom. A handle pivotally mounted on the casing carries a cam finger rotatable by planetary gear means including a stationary arcuate gear and a gear rotatable with the cam finger whereby, as the handle is pivoted to a locking position, the cam finger is given bodily movement to a position in alignment with the keeper and is also rotated between outward and inward positions to pick up the keeper and move it to a locked position within the casing.

Abstract: A crank drive assembly for sliding roof mechanisms of automobiles, in which a hand-operated crank drives a push-pull cable, the assembly including a releasable clutch between a drive shaft and a drive pinion transmitting the crank motion to the drive cable, and an arresting mechanism blocking the pinion, whenever the clutch mechanism is disengaged. The clutch mechanism and the arresting mechanism are simultaneously operated by a pivoting motion of the drive crank.
