Abstract: A relocking mechanism for a safe or like security closure comprises one or more relocking devices mounted on a panel of the closure rearwardly of the main bolt and operable to prevent retraction of the bolt. Each of the relocking devices includes a mounting plate carrying a pair of unidirectional hinges constituted by roller clutches, a plate-like bolt-engaging member being connected to the hinges for uni-directional pivotal movement from a disengaging position to bolt-engaging position. The bolt-engaging member is resiliently biassed towards the bolt-engaging position but is normally retained in the disengaging position by a control element which releases the member in the event of forcible attack on the closure.

Abstract: In a safe deposit apparatus of the type having a horizontally pivoted sector-shaped door with an interior pocket formed by a pivoted wall serving to eject articles from the pocket when the door is closed, the pivoted wall is normally biassed to the pocket-forming position and is displaceable therefrom to the ejecting position by a cam arrangement which becomes operable as the door is closed. Another cam arrangement maintains the pivoted wall in the ejecting position during opening the door. A locking mechanism permits opening of the door to a first position at which envelopes may be deposited, but prevents opening to a second position for the deposition of wallets except when released by a user's key.

Abstract: The invention provides a dual function safe deposit apparatus which may be operated either without a key to receive envelopes and deposit them in one compartment, or with a key to receive wallets and deposit them in another compartment. The apparatus has an opening to receive deposits, the opening being equipped with a withdrawable shield having a slot for the receipt of envelopes, withdrawal of the shield to provide a larger opening for wallets being key controlled and linked with movement of a diverter member which diverts wallets, deposited while the shield is withdrawn, into a separate compartment from that into which envelopes, inserted through the slot in the shield, are delivered.
