IMPROVEMENT IN DOOR-KEYS.
Specification forming part of Letters Patent No- 89,596, dated May 4, 1869.
- 2 to 4 are details of the same.
Lock-keys have heretofore been made from sheet metal, as in the instance of the keys adapted to the peculiar lock patented to Linus Yale, J r., J anua-ry 29, 1861.
Iain not aware, howe ver, that a key of this character has been constructed so as to be applicable to the common tumbler-lock as a substitute for the clumsy keys of cast metal universa-lly'in use. This my invention seeks to do, and thereby secure economy in construction with the convenience for being carried in 4 the pocket incident to the reduction in weight and size which the use of wrought in place of cast metal affords.
In the drawings, A, Fig. 2, is a key-blank, which, with the exception the scores to fit the wards in the edge of. the bit are afterward made by hand, is punched from sheet or plate steel or other suitable metal. In this shape the key has a bow, a, a shank, b, and a bit, 0, in one entire piece. In order to adapt it to the common lock, it is necessary to supply it with a stem, B. This, as seen at Figs. 3 and 4, may be made from a piece of wire, turned so as to leave a shoulder, d, for a stop to the key when put into the key-hole of a mortise or other lock having akey-hole upon each face.
A diagonal slit is out nearly through the axis, leaving the stem separated into two halves, except at the part 0 e, shaded dark.
. The top edge of the key-blank A is cut away at a corresponding angle, so that the stem, when soldered to the blank, as seen at Fig. 1, will have its axis coincide with the central axis of the shank of the blank. In this way a key can be very cheaply made which will not burden the pocket, and will possess all requisite strength.
What I claim as my invention, and desire to secure by Letters Patent, is-
A key for a lock whose bow a, shank b, and bit 0, made from sheet or plate metal, are combined with a stem, B, made separately therefrom,the article being constructed substantially as described.
