UNITED STATES PATENT OFFICE.
LAZARUS SIMON MAGNUS PYKE AND EDVARD STEPHEN HARRIS, OF LONDON, ENGLAND.
MAGNETIC INDUCTOR FOR DYNAMO-ELECTRIC MACHINES.
SPECIFICATION forming part of Letters Patent No. 476,818, dated June 14, 1892.
Application filed February 5, 1892. Serial No. 420,469. (No model.)
To LZZ whom it may concern:
Be it known that we, LAZARUs SIMON MAG- NUs PYKE and EDWARD STEPHEN HARRIS, electrical engineers and contractors, both of 34 New Tothill Street, in the city of festminster, England, have invented new and useful Improvements in Dynamo-Electric Machines, of which the following is afulhclear, and exact description.
This invention relates to dynamo-electric machines in which the magnetic-field inducing and induced wire coils are all stationary and in which electric currents are produced b v commutation of the magnetism by means of moving masses of magnetic material (commonly termed induetors usually composed of the softest iron laminae juxtaposed (with intervening sheets of paper) in such number as to form a mass of relatively great width in proportion to its thickness. These laminated induetors are subject to great magnetic and centrifugal strains, to resist which great rigidity is required. The laminaecomposing an inductor are usually bolted together and lixed to strong' metal supports by bolts in which, placed as they are in a powerful magnetic iield of varying intensity, eddy cu rrents producing local heat and waste of power are liable to be set up.
Our invention has for its object to mechanically strengthen the above-mentioned laminated induetors, so as to enable them better to resist the magnetic and mechanical strains to which they are exposed.
The invention consistsin the combination, with the soft-iron laminze, of thin laminze of a strengthening metal, preferably hard steel or bronze, interspersed with the soft-iron laminae in the numerical proportion of from about one of the strengthening metal to from six to twelve of the soft-iron laminre constituting the Inductor, the first and last plates preferably being of the strengthening metal and the whole being united by bolts of preferably German silver.
The accompanying drawing shows a perspective View of one of the induetors of the dynamo-electric machine described in another application for United States patent of even date herewith, No. 420,470; but the present invention is not limited to this particular machine, but is applicable to all machines of the same type.
c are the soft-iron laminae, (represented by line lines,) and l) the strengthening laminse of similar shape and linear dimensions to those a, with which they are interspersed, as represented by thick lines.
c are preferably German silver rivets or bolts uniting the whole together to constitute the magnetic inductor.
Then the inductor is required to be of the transversely-eurved form shown, the lamin would be assembled together upon a suitable formen temporarily clamped together by suitable means, and the whole mass drilled to receive the bolts or rivets. The advantages of this improved construction are less waste in eddy currents, cooler working, greater or more equally-distributed rigidity, less boltsurface, and less weight.
Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, we declare that what we claim isln dynamo-electric machines of the type in which the field-magnetinducing and induced wire coils are all fixed, a magnetic inductor composed of laminie of soft iron and laminzc of hard metal interspersed one with another for the purpose of strengthening the ind uctor, substantially as specified.
rlhe foregoing specification of our improvements in dynamo-electric machines signed by us this 12th day of January, 1892.
