Abstract: A door securing device has a body adapted for mounting on the door frame with a generally rectangular plate adjacent the body opposite the frame. The plate is attached to an arbor that slides axially perpendicularly to the inside wall. It is controlled by a groove and lug camming arrangement and can be rotated a selected amount to allow limited axial movement in selected rotational positions. The plate is shaped to clear the door when in a stowed position against the body. Pulled out, or actuated, the plate can rotate to place a plate extension in position to secure the door when slightly opened. The plate is moved back to stowing position by reversing the procedure engages the door in the closed position. A latch and latch release trigger is provided to release the arbor, and the plate, to extend to the actuated position.

Abstract: A locking mechanism comprises a housing, a shaft extending in the housing and having a latch member thereon adjacent to one end thereof, and an actuating lever adjacent to an opposite end of a shaft. The shaft, actuating lever, and housing are interconnected in a manner that causes the shaft to move longitudinally in response to turning of the actuating lever to a predetermined extent from a rest position, so that the latch member moves from a first position to a second position, and for causing the shaft to tilt in response to continued turning of the actuating lever, so that the latch member is turned away from the second position.

Abstract: A latch mechanism which engages with a main body is provided at pivoting edges of a keyboard and a cover which are provided at the main body so as to be openable and closable. The latch mechanism includes a latch member which is movable from a first position, at which the cover and the keyboard are engaged with the main body, to a second position, at which the engaged state of the cover and the keyboard with the main body is released. The latch member releases only the engaged state of the main body and the cover at a third position which is between the first position and the second position. Further, the latch member is usually urged to the first position by a compression coil spring which deforms upwardly in a convex shape at the second position of the latch member.

Abstract: A tumbler is pivotably mounted in a sash lock housing. In an extended position, an end of the tumbler limits movement of a window sash. A post in the housing extends through an eccentric bore in the tumbler. The bore defines a shelf or protrusion that urges the tumbler into engagement with the housing, thereby preventing over-rotation of the tumbler in the extended position. A spring urges the tumbler toward the extended position and cooperates with the protrusion to urge the tumbler into engagement with the housing.

Abstract: This device includes: (a) an access opening, (b) support structure located adjacent an edge of the access opening and containing a plurality of slots, and (c) a sheet-metal door having one edge located adjacent the support structure, having a closed position covering the access opening, and having a fully-open position in which the door is perpendicular to its position when closed. The door is swingable between its closed and fully-open positions about a pivot axis located near said one door edge. The door includes a plurality of tabs projecting outwardly from said one edge, each tab being of a generally L-shaped cross-section when viewed from a reference plane perpendicular to the pivot axis. Each tab comprises a first arm located in the major plane of the door and a second arm extending transversely of the first arm.

Abstract: A door lock has a body portion securable to a door jamb so as to project therefrom into a room, and a locking portion pivotally mounted on the body portion for angular movement relative thereto about a vertical axis between a locking position preventing opening of a door and an unlocking position permitting opening of the door. One of the portions has a projection engageable in a recess in the other portion to retain the locking portion in the locking position. The locking portion is capable of a limited amount of transverse movement relative to the body portion in a horizontal direction substantially perpendicular to the direction of opening movement of the door to enable the projection to be engaged in and disengaged from the recess.

Abstract: An apparatus for mechanically locking and unlocking a passenger access door panel on a railway vehicle which includes a locking lever arm, one end of which is pivotally secured to a movable door panel and having a roller secured at the opposite end, and having a biasing means to pivotally bias the roller against a locking support structure secured to a structure adjacent to the movable door panel when such door panel is moving into the closed position.

Abstract: A latch device includes a latch body provided in a housing so as to be movable in an inserted direction in which the latch body is inserted into the housing, and in a withdrawn direction in which the latch body is withdrawn from the housing, and being continuously urged in the withdrawn direction. Further, circulatory cam grooves are also provided in the housing, and a supporting member is inserted into the circulatory cam grooves and circulates and moves in the circulatory cam grooves so as to hold the latch body at an inserted state position and a withdrawn state position.

Abstract: A fire-retardant pivoted door assembly with fire activated latching members includes a metal door frame having jambs and a header in which a fire-retardant door is mounted by a hinge assembly with a lower temperature resistance that the door and frame. Fire actuated latch bolt assemblies in the door are spaced vertically along the hinge side of the door, and include a housing providing an elongated cavity opening at the edge of the door. A latch bolt is slidably seated in the cavity and is biased towards the opening of the cavity. A fusible closure extends across the opening of the cavity and retains the latch bolt against the biasing pressure, and the hinge jamb has a spaced recess formed therein to receive the latch bolt upon melting of the fusible closure.

Abstract: The present invention discloses a locking device for all forms of storm and screen doors. The device attaches between the door and the doorjamb and is secured into locking position by tightening a nut against a locking member. The device secures the door against intruders and against draft passing between the door and the doorjamb.

Abstract: A latch on a panel closing an opening in which the panel overlaps an edge portion forming the opening comprising a U-shaped channel with a short leg resting against the panel and the long leg extending behind the edge portion and including a bolt extending through the panel and short leg and threadedly attached to the long leg.

Abstract: The invention provides a device for securing a window sash to the outer frame of the window so that, on the one hand the sash may be locked in a predetermined open position and on the other hand may be pivoted to open it fully. A single push-button serves both to disengage a catch in the predetermined open position and to release the sash for full opening.

Abstract: Storage cabinets for storing single sets of punches and dies when not being used in tabletting machines. The tabletting machine customarily employs a single such set of punches and dies. A storage cabinet includes plural horizontal trays providing plural horizontal nests for horizontally storing punches. It also includes plural horizontal drawers for storing dies that match the stored punches. The cabinet also may include a lesser number of door-carried vertically oriented punch nests for storing vertically oriented punches. All of the stored punches are so situated that their operative surfaces are protected against striking metal objects so that they will not be nicked, scratched or dented, necessitating repair. The cabinets are of a proper size for modular storage on a toolmaker's steel shelving.
