ALBERT L. MARS H, OF DETROIT, MICHIGAN, ASSIGNOR TO HOSKIIIS MANUFACTURING COMPANY, OF DETROIT, MICHIGAN, A CORPORATIONOF MICHIGAN.
LABORATORY UTENSIL-HOLDER.
No Drawing.
Specification of Letters Patent.
Application filed November 11, 1910. Serial No. 591,911.
Be it known that I, ALBERT L. MARSH, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented a new and useful Improvement in Laboratory Utensil- Holders, of which the following is a specification.
The object of my invention is to provide holders, such as triangles, crucible-tongs tips, wire-gauze, and the like, employed 1n metallurgical laboratory work for supporting and handling the work, which shall endurably withstand the destructive tendency of the high temperatureto which they are subjected in use to destroy them and be particularly suitable for uantitative analytical work. When such olders are'made of any base metal, the heat to which they are subjected in use rapidly destroys them by oxidation, and the metal, in being broughtv into contact with the heated platinum or porcelain of which the crucibles and other ware are made, discolors the surfaces, adding to the weight of the ware and thus rendering such holders unfit for quantitative analytical work. To avoid, more particularly, the last-named objection, such holders are sometimes made of platinum because it remains unaffected b the heat, but its cost renders it practical v prohibitive for the purpose; and to enable a base that objection, sheathing the holder with fire-clay, fused silica, or the like, has been resorted to, but the metal soon burns out, so that the holder is lacking in desirable durability.
My invention provides a holder, in the class referred to, which is devoid of these objections, and it consists in' formin such holders of an alloy containing nic el or cobalt with chromium, and preferably also aluminum. I find that a holder composed of such an alloy effectually resists destruction by. heat, and remains otherwise unafi'ected injuriously thereby during prolonged use, because of the very high melting point of the nickel or cobalt and the property of the chromium of reducin to the minimum the tendency of the nicke or cobalt to oxidize. The value, for my purpose, of aluminum as a part of" the alloy is its effect under the influence of intense heat to produce an oxid which, combining with the oxids produced by the same infiuence from the other metals in the alloy, forms a continuous, very thin, dense and adherent non-scaling sheath or surface-coating, which protects the holder by insulating the body or interior of the structure against further oxidizing influence thereon. Moreover, the holder does not discolor. The

alloy is best suited for my improved article of holder, as imparting to it in the highest degree the desirable property herein. described, when com osed of about eighty per cent. nickel or co alt, about eighteen per cent. chromium and about two per cent. aluminum.
What I claim as new and desire to secure by Letters Patent is- 1. A holder having the properties set forth, for receptacles employed in metallurgical laboratory work of the character described, formed of an alloy of chromium with a metal having the properties of nickel and cobalt.
2. A holder having the properties set-
