Builder's hardware; a manual for architects, builders and house furnishers . raw the armature A away from the cam, B, permit-ting the knob to be turned.

The Thaxter andthe Fuller locks arethe ones most com-monly employed in andaround Boston, thoughthere are several othermakes in the market,most of which are,however, asserted to beinfringements of thepatents. Sliding-door Lochs.— Figures 847 and 348illustrate two types ofsliding-door latch andlock. The lockingmechanism used forthis purpose is usuallyquite cheap in its con-struction, as a finelyfitted lock is seldomrequired for sliding-doors. Indeed in manycases no lock at all isnecessary. The bolt iscurved and hooksdown into the face-plate on the opposite door or on the door-pull is either in the form of a hinged-lever, as inFigure 847, or a straight pull reinforced by a concealed spring,as in Figure 848. Both pulls can be pushed in flush with theface-plate. In some localities it is thought desirable to use. Fig 346 Electric Lock. Fuller & Holzer.
