UNITED STATES PATENT OFFICE.-
ALBERT I. MARSH, OF DETROIT, MICHIGAN; ASSIGNOB TO HOSKINS MANU'FACTUBIE'G. COMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN.
ELECTRICAL RESISTANCE ELEMENT.
1,057,753. No Drawing.
To all whom it may concern: Be it known that I, ALBERT L. MARSH, 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 Electrical Resistance Elements, of which the following is a specification.
' My invention relates to an electrical resistance element adapted for general use but primarily for the production of heat in heating devices. In devices of this character, the factor of principal importance is durability, which it is practically impossible to predetermine except by actual test under conditions approximating those of use. By
such test I have discovered that a resistance element formed of an alloy of iron and aluminum possesses great durability, combined with sufiicient resistivity that it may conveniently be built into translators of the character specified, its resistivity being 94 microhms per centimeter cube when 10 per cent. aluminum is used. f
In practice, I prefer to use an alloy in which the aluminum is from 5 to 10 per cent.
The addition of larger quantities of aluminum renders the alloy diificult to roll, but

may make it possible to work higher percentages. Of course it will be understood that my invention com rehends not only the use of the alloy spec' ed, but as well, the
the advance in metal working knowledge same alloy with additions of various othermetals, for .I have learned that when the suitability of a resistanceelement is once discovered, it may suffer the addition of considerable quantities of other metals without being materially injured or, in fact, changed to any noticeable extent, although insome cases, the addition of elements pro-1' duces quite extraordinary changes.
I claim as new and desire to secure Letters Patent 1. An electrical resistance element adapt ed to withstand a high temperature formed of an alloy consisting of iron and aluminum.
. 2. An electrical resistance element adapt: ed to withstand a high temperature formed of an alloy consisting of iron and aluminum the aluminum being in the proportion o from 5 to 10 per cent. 7
