    摘要: The invention comprises a latching and unlatching device for use on a door, or bulkhead, or the like, which device has a blocking plate for internally obstructing the latch to prevent its retraction, thereby to prevent the opening of the door. The blocking plate is internally secured in place, in an intermediate slidable position, where it does not obstruct the latch, by a low melting point cover. In the presence of excessive heat, as on the occurence of fire, the cover melts; this allows the blocking plate to slide to another, operative position in which it prevents the retraction of the latch and, consequently, the unlatching of the device. The method comprises the steps to be undertaken to modify an off-the-shelf latching and unlatching device to insure that it will be held securely latched in the presence of fire or excessive heat, and the kit sets forth the structure elements required for the aforesaid modification of off-the-shelf, latching and unlatching devices.

    摘要: In the preferred embodiment depicted, the invention comprises a limb, having a depending lug, fixed to a door. The lug makes a close clearance, near engagement with a socket-retainer fixed to a door-interfacing mullion. The upper end of the mullion is foreshortened, and addressed to a free space; it is slidably engaged with an internal socket. Accordingly, in the event of fire, the mullion may freely extend vertically, due to the heat. Such free extension causes the socket-retainer, and the depending lug, mutually to engage. By this arrangement, the door is secured closed, on the exposure to severe heat, even if the normal latching and/or locking device therefor comes loose or disengaged. The method comprehends fixing the mullion at one end, securing it against angular movement, exposing the other end to a free space, and mounting to the closure and mullion locking components which come into engagement only in response to thermal extension of the mullion.

    摘要: An exit device includes a housing, a latchbolt coupled to and movable relative to the housing, and an auxiliary bolt coupled to the housing and movable relative to the latchbolt. The exit device also includes a deadlock link coupled to the housing and movable relative to the latchbolt and the auxiliary bolt between a first position, in which the deadlock link allows movement of the latchbolt relative to the housing, and a second position, in which the deadlock link inhibits movement of the latchbolt relative to the housing. The exit device further includes a spring biasing the auxiliary bolt into engagement with a portion of the deadlock link to move the deadlock link toward the first position.

    摘要: A fire-rated removable mullion, includes a top fitting mounted to a door frame lintel, a bottom fitting assembly, a mullion head capable of detachably engaging the top fitting, a mullion tube having provisions for mounting between the mullion head and the bottom fitting assembly, and another provision for accommodating thermal expansion of the mullion assembly to resist warping of the assembly. Where desired, a mortise cylinder lock can be included to limit removal by unauthorized persons.
