This invention relates to a design for that class ot' keys which are iliade from sheet metal, commonly called ilat keys, and the design consists 1n the configuration ot' the bow and shank,-as shown in thc accompanying illustration, and hereinafter described.
The bow has t'our sides, in substantially the shape of a parallclogxram--the one side, a, at right angles to the shank, and the two sides b b at right angles to the side a., and parallel to each other. The angles are slightly rounded. The fourth or outer side has a central curve, c,
running into the continua-tion ot" the curves at the angle, so as to t'orm au indentation, (I, at the intersection ofthe curves-that is to say, the outer side is composed of two small semicircles, with an intermediate segment connecting them.
The shank A ofthe key is reduced from the width at the hit end toward the bow, and at thejunction of the shank with the how a semicircular notch, c, is made at cach side, as shown in the accompanying illustration. The key, however, may be made without this peculiar shape ofthe shank.
