Abstract

643.943. Locks. START, P. W., and CHUBB & SONS LOCK & SAFE CO., Ltd. June 11, 1948, No. 15796. [Class 44] The casing for a padlock comprises a body portion 1 and a cover plate 13 fitted into a stepped recess 12 in the body and secured therein by the rim 15 of the recess being turned over to engage the edge of the cover plate. The turning over is effected by a spinning or pressing operation. The body portion is integrally formed and may be a drop forging comprising projecting lugs 5 to receive the pivoted yoke 6 and a cylindrical bore through which the free end of the yoke enters the recess 10 in the casing. The outside of the cover plate is chamfered at 14 to form a groove into which the rim 15 is forced. Pins 18, providing pivotal mounting for the parts of the lock mechanism may be integral with, or secured to, the rear wall of the casing and adapted to abut the cover plate 13 to prevent its being forced in. Similar pins may be mounted on the cover plate.
