Abstract

445,444. Lever locks. CHUBB & SON'S LOCK & SAFE CO., Ltd., 128, Queen Victoria Street, London, and START, P. W., Shirley, Stafford Road, Oxley, Wolverhampton. March 22, 1935, No. 9024. [Class 44] A lever look has one or more of the pivoted levers so formed that they present an abutment in the path of a key which has not effected the normal throw of the bolt and prevents withdrawal of the key to give warning that the lock is insecure. One or more of the levers has a tail piece e, Fig. 4, or an abutment m, Fig. 6, which obstructs the complete rotation of the key whenever the stump i on the bolt moves insufficiently far to allow the levers to move into their normal locking position.
