Abstract: A reversible lock follower assembly for a mortise lock having a housing for accommodating the mortise lock components and a front plate for attachment to an edge of a door is described that allows for selective reversibility of the lock follower assembly without any disassembly of the mortise lock housing. The reversible lock follower assembly comprises: (i) a follower body having a side facing the front plate and an opposite side having a bore; (ii) a coil spring placed in the bore; (iii) a follower ball engaged with the coil spring; (iv) a follower locking piece selectively movable within a slot of the follower body having a spindle hub engaging end and a follower body engaging end; and (v) a first aperture on the follower body engaging end to receive the follower ball when the locking piece is in a first position and a second aperture on the follower body engaging end to receive the follower ball when the locking piece is in a second position.

Abstract: A lockset for a door has knobs which are generally conical in shape and tapered inwardly with distance from the door surface to prevent attachment of a noose. Finger receiving concavities are provided circumferentially about the inward tapering surface of the knob to facilitate grasping without providing any projection about which a noose can be secured. One or both knobs of the lockset can optionally be provided with a handle at its pistol end from the door which can be grasped between fingers to further enhance gripping ability while avoiding the provision of a projection to which a noose can be attached.

Abstract: A lock, particularly adapted for use with the gate of a woven-wire partition, includes a housing having a faceplate, a wall projecting from the faceplate and substantially surrounding the interior of the housing, and a removable cover for closing the housing. A stationary bracket is located within the housing, and a latch is movable with respect to the housing between latched and unlatched positions, in response to operation of manually-manipulable means, such as a key-operable lock cylinder or a hand-operable fingerpiece. A member within the housing is cooperable with the stationary bracket for preventing movement of the latch in a direction transverse to the plane of the faceplate, so as to prevent the latch from accidentally falling out of the housing when the housing cover is removed and the housing is open. A spring within the housing serves two functions, namely, constantly urging the latch toward its unlatched position, and maintaining cooperation between the member and the bracket.

Abstract: A lock cylinder for use with either a deadbolt lock or a key-in-the-knob lock. The lock cylinder includes a hollow cylindrical body having a radially projecting, pin-containing chamber, extending along the length of the body, and a cylinder plug rotatably accommodated within the body. The plug holds a series of pins, which can be brought into alignment with the pins in the chamber, and the plug has a slot for accepting a key. Two tailpieces are provided, either of which may be alternatively secured to the cylinder plug in non-rotatable relationship to the plug. One of the tailpieces is cooperable with the mechanism for operating a deadbolt lock, and the other tailpiece is cooperable with the mechanism for operating a key-in-the-knob lock. One end of the cylinder plug is formed with a transverse slot and an annular slot, an extension at one end of each tailpiece fitting into the transverse slot, and a resilient snap ring fitting into the annular slot to prevent separation of the tailpiece from the plug.

Abstract: A reversible mortise lockset for use with an ornamental metal security storm door furnished with a lock box, each of the two opposed vertical walls of the lock box having two vertically aligned holes of equal diameter. The lockset includes a mortise lock which can be inserted into the lock box in either of two alternative orientations, namely, the lock cylinder hole of the mortise lock in registry with the upper holes in the lock box or the lock cylinder hole of the mortise lock in registry with the lower holes in the lock box. In either orientation, the door knob spindle hole and a through bolt hole of the mortise lock are exposed through the lock box holes not in registry with the lock cylinder hole. A pair of plates are provided for mounting on the exterior surfaces of the lock box walls, each plate having a door knob and spindle near one end and a lock cylinder hole near the other end. One of the plates has a single mounting post projecting parallel to the door knob spindle.

Abstract: A reversible mortise lock including a housing having a front plate and side walls, and a latch movable between an extended position in which it projects through the front plate, and a retracted position. Two spindle hubs, for cooperation with the spindles of inner and outer door knobs, are independently pivotable about a fixed axis, the latch moving from its extended to retracted position in response to pivotal movement of either spindle hub. An abutment member is pivotable between two extreme positions; in one extreme position it interferes with pivotal movement of one spindle hub, but not the other, so as to prevent that one hub from causing retracting movement of the latch; in the other extreme position, the abutment member does not interfere with movement of either spindle hub. The abutment member is exposed through an opening in the front plate so that it can be swung between its extreme positions by finger pressure.

Abstract: A tent is supported by outwardly leaning pairs of arches and an interconnecting flexible ridge member having a special fitting at each end. The ridge member is associated with the outer cover by positioning in a tunnel formed in the outer cover, so that the outer cover may be tensioned to form the shelter. The special fitting may be positioned in a grommet in the outer cover at one end while the identical special fitting at the other end may be used for tensioning.

Abstract: A double walled tent is supported by outwardly leaning pairs of arches and an interconnecting flexible ridge member. The ridge member is associated with the outer wall or cover, so that the outer wall may be tensioned to form the shelter. An inner wall or cover is suspended from the outer wall by netted webbing which allows circulation between the walls.
