Abstract
313,800. Gibbons, F. Aug. 4, 1928. Locks.-In the manufacture of rim-lock cases the ends of the base plate are bent up and riveted to the rim sections in one operation which may also serve to rivet in any supporting stumps required. The rim sections b are clamped in position on a lower die D, Fig. 3, by pivoted members E against the pressure of releasing- springs, and the base plate A is located with its ends overlapping the die by pins h which enter holes in the base plate. Instead of pins h stumps may be located in the lower die for riveting into' the base plate by the upper die B. The die B has a spring hold-down G which serves also as an ejector in conjunction with hooks J. Re. newable dies c have their corners rounded at m to bend down the ends of the base, holes f taking over projections e during the operation. The projections are received in slots m in the dies c until the bend is completed when the projections pass from the slots and are riveted by the plane face of the dies. Recesses may be formed in the die D to receive abutments on the rim section to support the cap plate of the lock and these abutments may be provided with projections which are also riveted into the base by the dies. When a bent up rim is employed the dies are arranged to bend up one side of the base only.
