Finger Joint Hinge





is a finger joint—a movable interlocking joint used to support the leaf of a Pembroke table. The small portion is screwed to the table rail and the shaped bracket swings out to support the drop leaf. The shaded portion of the bracket shows the timber chamfered away so that the fingers may be easily put behind the bracket to manipulate it. Note that the corners are slightly rounded off, as indicated by the black portion of the sketch, and that the mortises are cut about 1⁄4 in. deeper than the thickness of the timber used. This joint has now been almost superseded by a cheap stamped galvanised iron bracket of exactly the same pattern. The joint, however, is still used for repair work and in cases where a stamped metal bracket has not sufficient overhang.
