UNITED STATES PATENT OFFICE.
IMPROVEMENT IN MAGNETO-ELECTRIC MACHINES.
Specication forming part of Letters Patent No. 123,438, dated February 6, 1872.
To all whom it may concern:
Be it known that I, ALMON N. ALLEN, oiA Pittsti eld, in the county oi' Berkshire and State oi' Massachusetts, have invented a new and useful Improvement in Magneto-Electric Machine, and I do hereby declare the following to be a tull, clear, and exact description thereoi,\vhich will enable those skilled in the art to malte and use the same, reference being had to the accompanying drawing' forming part ot' this specification, in which drawing- Figure l represents a sectional front View ol' my invention. Fig. 2 is a horizontal section of the same.
Similar letters indicate corresponding parts.
This invention relates to a magnetoelectric machine composed ot' a series of permanent magnets placed side by side so as to i'orm a cylindrical case open at both sides, into which case is vlitted the core oi a helix, mounted on an arbor, which carries the commutator, and to which a rapid revolyin motion can be imparted in such a manner that by inclosing the core or' the helix in the magnetic cylinder the power ol' the induced current is materially increased and a magneto-electric machine is obA tained which is cheap, durable, and oi' superior power.
ln the drawing, the letters A A A designate a series of horseshoe magnets, Which are grouped together so as to form a cylinder open at both sides, as shown in Fig. 2. Into this magnetic cylinder is iitted the core B, by prei'- erence made oi" soft iron, with tWo side iianges, c c, and a connecting cross-bar, b, said side ilan ges being made in the i'orin ot' segments, (see Fig. 9,) which conform to the bore of the magnetic cylinder, and run close to the inner circumference thereoi',without, however, touching the same. The core B. is mounted on an arbor, G, which has its bearings in cross-bars D l), fastened to the magnetic cylinder, said cross-bars being, by preference, made of brass or other non-magnetic material. On the arbor C is also mounted the commutator E, which is constructed of two parts, c d, one of which is in metallic contact With the arbor, while the other is insulated therefrom, and which may be fitted one over the other, or which may be arranged side by side, as shown in Fig. l. On the core B is Wound the helix F of the insulated copper Wire, and one end of this Wire is connected to the insulated portion of the commutator, While its other end connects with the arbor U, or With any part that is in metallic Contact with the non-insulated portion of the commutator. W'it-h the commutator are conibined two springs, c j', which bear thereon from opposite sides, said commutator being so arranged that it' one spring bears on the insulated portion oi' said commutator the other will bear on the non-insulated portion, and Vice versa. From the commutator-springs e j' extend the Wires l0 and ll, which conduct the electricity produced by the machine to the place where the same is to be employed. The motion of the arbor C is produced by hand or by any desirable power', and if the arbor is revolved a current oi' electricity is produced which can be used for lighting gas or for any other purpose.
What l claim as new, and desire to secure by Letters Patent, is-
The arrangement of a magnetic cylinder, A A A, formed as herein described and inclosing the core B, with the helix F, substantially as set forth.

F. M. HAYDEE, JOHN H. ROLEE.
