Locking actions for pedestal drawers, in which the locking of one drawer—usually at the top— automatically secures all the other drawers in the pedestal, were usually effected by incorporating a spring-loaded vertical sliding bar at the rear of the carcass. Arms or pegs were attached to the bar which engaged in slots cut in the drawer sides, and a sloping ramp cut into the top drawer side automatically raised all the pegs and thus released all the other drawers as the top drawer was partially withdrawn, while if the drawer was pushed fully home then a back spring attached to the bar pulled the pegs down into the slots. The disadvantages of this older method are obvious, and improved types are shown in 268 in which the throw of the desk lock itself actuates the pegs. Both are particular types of pedestal locking actions. 268:1 shows one variety in which the throw of the lock rotates a cog which engages in a metal rack so that the slider with its pegs (268:3A) is forced downwards, releasing the drawers. The cylinder of the lock is mortised into the edge of the carcass side (268:2) and held in position with a pronged plate (268: IB) mortised in from the side, while the metal slider moves freely behind two or more metal strips (268:1 A) which are recessed in and screwed to the inner carcass face. Slots are cut into the bottom of the drawer sides (268:3) and corresponding slots in the drawer rails (X) in the elevation (268:5) to accommodate the travel. The exact position and number of the pegs must be clearly detailed when ordering as there are no standard dimensions. For the small user not ordering in quantity the other lock (268:4) is more suitable, as the pegs are freely adjustable and can be fixed at the required distances by turning the slotted heads. This particular type of lock is mortised into the knee-hole side of the pedestal at a convenient distance under the top (268:6). Both these locks must be ordered right or left hand, and in both also the metal slider (268:1 A, 4A) can be recessed in flush as 268:2, or face screwed as 268:5 in which case drawer guides (Y, Y) must be fitted to fill the gap. As with all fittings of a specialist nature the unit should be designed round the fitting rather than the fitting laboriously altered to fit an arbitrary design. Other types of these locks are available, and the designer should consult the catalogue of his usual supplier for further details.
