Abstract: A door locking mechanism for deadlocking a door. The door locking mechanism includes a lockhead member which includes a door stopping portion. The lockhead member is moveable from a locked position, wherein the door is double deadlocked, and an unlocked position. A vertical locking mechanism is coupled to the lockhead member, and the vertical locking mechanism deadlocks the door when the lockhead member is in the locked position. The door stopping portion of the lockhead member also deadlocks door when the lockhead member is in the locked position. A carriage assembly is engaged with the door, and the carriage assembly is engageable with the door stopping portion and moves the lockhead member from the locked position to the unlocked position. The vertical locking mechanism disengages the door when the lockhead member is in the unlocked position and the door stopping portion of the lockhead member also disengages the door.

Abstract: A set/operate mode switch is interposed between the door sensing or element door position activated switch and a remote monitoring station, to enable the remote station to monitor the door condition, or to enable a local signal assembly to monitor the door condition. The local signal assembly is made operative by the set/operate switch, so that the sensing element can be accurately set before turning door monitoring over to the remote station. While the local signal assembly is verifying the door condition, a shunt or shorting element keeps the remote monitoring station displaying a door open condition, all the while that the local signal assembly is operatively engaged, for security reasons. Only when the local signal assembly is isolated from the arrangement, can the remote monitoring station give a true signal of the door condition.

Abstract: A detention cell locking system affording improved securement and reliability in the locking network of multiple detention cell doors. Mechanical actuation linkages are interconnected for motion responsive to either select manual, mechanical, or electrical signals actuating a DC motor drive. The locking mechanism incorporates an elongate toggle plate mounted to a carriage plate and a pair of cell door support rollers forming part of a mechanical locking system. The toggle plate assembly on the carriage plate permits a turning moment to be generated for lost motion actuation which effects locking and unlocking of the detention cell doors. A control network determines the length of time that the DC motor is electrically actuated and disengages the power to the motor during manual mechanical actuation.

Abstract: A symmetrical cell door and operating system comprises a vertically shiftable locking bar mounted in a center column of a cell opening. A cell door is movable in either direction relative to the central column and has upwardly facing locking notches in a lower horizontal frame element to receive the lower end of the locking bar to lock the cell door when moved either to the extreme right or to the extreme left of the center column. An elongated rack is secured to the top of the cell door by a lost motion connection and defines a cam slot engagable with a horizontally projecting actuator on the locking rod to cam the locking bar into and out of the respective locking notch. The rack is reciprocated by a pinion driven by a DC motor.

Abstract: A prison cell door locking device which responds to four locking modes of a prison cell locking system which uses a master bar assembly controllable from a central location to (1) release the locks of all cells, (2) lock all of the cells, (3) allow key operation of the locks at each individual cell, or (4) allow electric operation of the cell locks from the central location is provided. The device is fully assembled on a mounting plate which is provided with means for alignment with and securing onto the frame of a prison cell, and for connection to the cell door locking member. The assembled device contains mechanical and electrical components to operate the cell locks in all four modes. The device includes a master bar section which is permanently connectable into the master bar assembly, without further alignment, by long hollow channels of light weight metal.

Abstract: A jail-cell door is suspended from an overhead carriage, for horizontal displacement between closed and open positions, and an elongate slide bar has a horizontal lost-motion connection to the carriage. The slide bar mounts a reversible electric motor and is continuously engaged to the driven one of two rollers from which the carriage and its cell door are suspended; the shaft for the other suspension roller is journaled in the carriage. For driving the cell door in the door-opening direction, the outer lost-motion limit determines an expanded wheelbase of door suspension, and for driving the cell door in the door-closing direction, the inner lost-motion limit determines a slightly reduced wheelbase of door suspension. The slide bar carries cam formations at or near its respective ends for determining locking-bolt action only at the fully closed and fully open positions of the door, and a deadlock device is pivotally carried at one end of the slide bar, serving the door-closed condition.

Abstract: A locking assembly suitable for a plurality of sliding doors is disclosed. The assembly includes, at each door, a vertical drop bar in the door jamb with catches for engaging and locking the door at preferably two locations when the bar is lowered and the door is closed. The bar may be lifted by three different means: by a remotely operable motor which may be actuated to rotate a cam through one revolution, thereby lifting up on a rigid horizontal extension of the drop bar; by rotating a key in a key cylinder, which operates a similar rotatable cam to raise the bar; and by an emergency release mechanism including a manually slidable linkage member at the top of the frame, effective when its position is shifted to mechanically lift the drop bar. A deadlock is preferably provided to normally lock the bar in its lower, locking position, the deadlock being releasable upon actuation of any of the three drop bar lifting means.
