Abstract

270,094. Ralls, J. C. May 17, 1926. Lock-mechanism, levertype; master-key; padlocks; locks, preventing drilling of.-Lever locks of the kind described in Specifications 27133/96, 2604/97, and 11988/10 wherein adjacent members of a series of pivoted gated levers are moved in opposite directions by a key to align the gatings with a stump on the bolt, have a drill-proof shield secured to the uppermost lever. This shield b is riveted or welded to the uppermost lever a and prevents the unauthorized drilling of a new set of gatings c to accommodate the stump d on the bolt or shackle e of the lock. The levers may be double-ended, Fig. 10, for blocking a pair of bolts e, e. When the lock is adapted for use with master and servant keys, the lug g dividing the gating c aligned with the stump d by the servant key and the gating f aligned by the master key, is carried on the underside of the shield.
