Definitions

This invention is particularly applicable to electric railways in which one or more of the rails forms a continuous conductor for carrying the electricity to a motor running upon said rail; and it consists in having a compound rail having an iron surface and independent copper conductor not presented to the wearing action ofthe wheel.
M represents the iron or steel portion
N the copper portion
the object of this invention is to have a wearing-surface upon which the wheels shall run In this case an allowance should be made with- I in the body of the rail for the expansion and contraction of the independent copper conductor. Other good conductors beside copper might be employed. f
a compoundv rail for electric railways consisting of a strip or section of copper or other good electrical conductor, and a carsupporting section of iron or steel, substantiallyas set forth.

If'yw 3 UNITED STATES PATENT OEEICE.

LEO DAFT, OF GREENVILLE, NEW JERSEY.

RAIL FOR ELECTRIC RAILWAYS.

SIECIFICATION forming part -of Letters Patent No. 283,760, dated August 28, 1883. Application tiled March 27. 1883. (No model.) u

To @ZZ whom it 11m/y concern:

Be it known that I, LEO DAET, a citizen of Great Britain, and a resident of Greenville, State of New Jersey, have'invented a new and useful Improvement in Rails for Electric Railways, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

This invention is particularly applicable to electric railways in which one or more of the rails forms a continuous conductor for carrying the electricity to a motor running upon said rail; and it consists in having a compound rail having an iron surface and independent copper conductor not presented to the wearing action ofthe wheel.

My invention will be readily understood from the accompanying drawings, in which Figuresl., 2, and 3 representdifferent forms of rail. y l

In these drawings, M represents the iron or steel portion, and Nthe copper portion. The copper portion in each case, it will be observed, is protected from wear.

. The object of this invention is to have a wearing-surface upon which the wheels shall run In this case an allowance should be made with- I in the body of the rail for the expansion and contraction of the independent copper conductor. Other good conductors beside copper might be employed. f

What I claim as my invention, and desire to secure by Letters Patent, is-

l. A compoundv rail for electric railways, consisting of a strip or section of copper or other good electrical conductor, and a carsupporting section of iron or steel, substantiallyas set forth.

v2. A compound rail for electric railways, consisting of a hollow section of iron or steel, and an inner strip or section of copper inclosed by the iron section, substantially as set forth.
