metal, having the interior surface, B, Fig. 1, to incline or converge from the outer rim, 0, toward and terminate at the central orifice or key-hole, A. The lower face of the interior surface, D,.Fig. 1, should be nearly orquite on a level with the lower ed geof the-orifieeA, so that the shaft of the key will always enter at its corresponding part of the orifice I attach the flange t0 the door or look in such a manner that the rim C will project outward and the orifice A will communicate perfectly with the key-hole of the lock.
' Fig. 2 is a perspective view of a door-lock, with the flange F shown as a part of and continuous with the outer plate of the same.
The object of this invention is to facilitate the insertion o'fa key into a look by giving it a wider'range of application, using for that purpose aflaring metallic flange,substantially the same as above described.
