ABSTRACT:
A telephone index comprises a box stand on which a telephone can be placed and an index comprising a stack of cards in a drawer, any selected one of which can be presented for inspection upon pressing the respective one of a plurality of buttons. Levers are mounted in an upper part of the box and extend from the front towards the rear thereof, the levers are pivotably mounted about a common transverse and generally horizontal axis located at a position forward of the push buttons and each co-operates with a respective one of the push buttons such that pressing any one of the push buttons depresses a rearwardly extending arm of a respective one of the levers to move a downwardly extending projection at the rear end of the lever downwardly into engagement with an abutment surface and raises a forwardly extending arm of the lever against the bias of a spring to trip a drawer catch to allow the spring biassed drawer to open. Each of the cards has at least one extension at its rear end, the extensions having apertures therein through which selected ones of said downwardly extending projections can pass to secure the cards against outward movement with the drawer.
