JOHN FARREL, OF NEIV YORK, N. Y.
METALLIC ALLOY FOR SAFES.
SPECIFICATION forming part of Letters Patent No. 298,365, dated May 13, 1884-.
Application filed November 2, 1883. (Specimens) To ctZZ whom it may concern Be it known that I, JOHN FARREL, of New York city, New York, have invented a Metallic Alloy for Safes, whereof the following is a specification.
The metal made from franklinite ore is one of the hardest metals known, and, being well adapted for resisting the action of drills and other cutting-tools, is extensively used bymyself and others in the construction of burglarproof safes. It is, however, more or less porous and friable from the peculiarity of its crystalline structure, and this friability is a weakness, inducing the metal to pulverize under the drill when applied with great pressure. My newalloy is not thus susceptible, and yet is as hard as or harder than franklinite and metals of the same character. It is made by melting up tin-scrapsuch as the waste or scraps from tinware-manufactureand combining the same with soft wrought-iron, combined with the franklinite iron, or that made from the spathic ores. It may be variously rnade; but I have practiced the following way with success: I take the tin-plate scraps, melt them down, and run the metal into molds for castings of a convenient form for remelting. I then take about an equal quantity, by weight, of this compound and of a franklinite iron, put both in a cupola, and'fuse them together at a very high heat. I then draw off this molten metal and pour it into molds prepared and adapted for bringing out the article or articles desired. Another way is to compress the scrap-tin into bundles and melt it up with the franklinite at once. The metal or alloy so compounded when cold is harder, tougher,
burglar-proof safes, and because its hardness I is natural and cannot be affected by the local application of heat. The alloy may also be used for journal-boxes, for dies for stamping,
and rolls for rolling sheet metals, andfor other purposes. All articles made from this metal or alloy should be cast at once to the size and N v shape required, if possible; and if not, the finishing must be by grinding the surfaceas by corundum-wheels-because it is nearly impossible to work the metal with cutting-tools.
My said invention is restricted to the ingredients herein specified. Nevertheless, I do not confine myself to the exact proportions indicated, but shall vary the same when found necessary; and instead of the franklinite the similar metal known as spiegeleisen may be substituted with good effect; but the franklinite is preferable.
I claim as my invention 1. The new composite metal or alloy of tinplate scrap, iron, and franklinite iron or its equivalent, substantially as described.
2. The method of formingacomposite metal of tin-plate scrap, iron, and franklinite iron 01' its equivalent, substantially as described, consisting in melting the ordinary tin-scrap to form an alloy, and fusing this alloy at the same time or subsequently with the franklinite:
