Description
NITED STATES PATENT Ormea.
LINUS YALE, JR., OF NEWPORT, FEW- YORK.
vAu LTS, atc.
Specification-forming part of Letters Patent No. 9,350, dated October 19, 1852.
To all whom t may concern Be it known that I, LINUS YALE, Jr., of Newport, in the county of Herkimer and State of New York, have invented a new and Improved Method of Making Burglar-Proof Ilates, Doors, and'Ohests of (last and Malleable Iron 5 and I do hereby declare the following to be a full and exact description of the same.
The method I have invented obviates the difliculties heretofore experienced in the use of cast-iron or any of the old combinations of cast and malleable iron for the above-named purposes-wiz., first, the brittleness of castiron; secondly, the usually-exposed position of the malleable iron to the drill and chisel of the burglar, these objections, one or both,
existing` against all previously-invented defenses of this kind made of these materials.
To enable others skilled in the art to use my invention, I will proceed to describe its construction, reference being had to the annexed drawings, forming part of this specilication.
Upon the edges of the pattern for the intended plate or door I put core prints, which when the mold is made, form a resting-place for the malleable iron. This pattern is molded in the usual manner, and before the flask is closed I place transversely rods of malleable iron in the core prints before mentioned, which are thus supported about midway of the mold, and around which the melted iron runs and incloses them when poured in the usual manner. These rods I usually interweave, as seen in Fig. 1, and also in section, Fig. 2; or they may be simply crossed, as in Fig. 3,orsection,Fig. 4; orthey may be looped together, as in Fig. 5, or bent without crossing, as in Fig 6, in either of which ways they answer the purpose intended-viz., to protect the plate or door from being separated when fractured.
I do not use straight rods without crossing, becausethe plate or door, Ste., might be fractured through :its whole extent without the line of fracture crossing a rod, and this it would be liable to, inasmuch as the line of fracture commonly follows the line of the rods. Thus the door or plate, 85e., being completely broken into two separate parts that are not tied by bent or crossed rods or their equivalents, is rendered worthless.
These particular methods of combining malleable and cast iron, necessitating as they do the use of crossed or bent rods or their equivalents, are essential in the new and improved process of manufacturing burglar-proofplates, doors, Sac., that I have invented.
The process thus far detailed produces a platev or door which is a sufficient protection against blows or pressure.
Combined with the above process, as a security against the drill and chisel of the burglar, I arrange in the mold a chill plate or plates in such manner as to harden 011e or both sides of the required plate or door. This et'- fectually prevents drilling a series of holes or cutting a circular or other groove, thereby enabling the operator to remove a portion of said plate or door, &c.
The proportion between the thickness of the plate and the spaces between the malleable rods should be such that the plate would not by ordinary means be broken into pieces of less diameter than the meshes orspaces bctween the rods. It will be seen that should the plate be broken ,thus small and the fracture follow the line of the rods, the pieces could not be withdrawn, owing to the fact that the half of the diameter of the rods would be einbedded in the edges of each piece, the shape of said pieces being such asl seen in Fig. 7; neither could the rods be sheared oft` at the line of fracture, as there would be no stability of one part for another to shear against.
I do not claim in said plates, doors, and chests the castin gin of straight rods or bars of malleable iron, or their equivalents, embedded parallel with each other vin only one general direction.
What Ielairn as new and of. my invention,
and desire to secure by Letters Patent, is-
A method of 'making burglar proof plates, doors, and chests of iron, which, in the process of being cast into the form. required for such plates, doors, and chests, surrounds or embeds malleable-iron rods or bars, or their equivalents, arranged substantially as described and shown by the specification and drawings herewith accompanied, or in an equivalen t manner.
