IMPROVEMENT IN ELECTRO-MAGNETIC ENGINES.

Specification forming part of Letters Patent No.7 ,287, dated April 16, 1850.

To all whom it may concern.-

Be it known that I, JOHN H. LILLTE, of Joliet, inthe county of Will and State ofIllinois, have invented a new and useful Machine for Electro-Magnetic Power; and I do hereby declare that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known, and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, in Which- Fignre 1 is a top plan. Fig. 2 is a bottom plan. Fig. Sis a side elevation.

My invention consists inthe employmentof a number ot' permanent horseshoe-magnets, compound or single, revolving` on a wheel in front of an electro magnet or magnets fixed stationary to the frame; and in conjunction therewith I-employ a helix of tine wire around scribed..

The construction of the apparatus is as follows: A series of any given number of permanent 'compound -or single U magnets, a, are placed in a wheel, b, properly constructed for the purpose, in a radial positiomwith their poles project-ing a little beyond the periphery of the wheel, as clearly shown in the drawings. Onone end of the axis of this -wheel there is a large spur-wheel, c, which drives two pinions, d, to which the brake-pieces are attached, to be more particularly described hereinafter.

The frame on which the wheel is supported serves to hold two electro-magnets, or more, as the case requires. vThese electro-magnets e are on a line radial fromV the shaft, one on each side, and are constructed in any ot' the Well-known waysof U`-formed electro-magnets. Around the coils upon these magnets are iine wires f. (Represented by red lines, the blue lines being the wires of the magnet.) These secondary coils f are connected with electro-magnets g, placed below, as seen in the drawings, Where they form a circuit and cause the `electro-magnets gto be magnetized by means of this arrangement, and for the purpose also of destroying the secondary currents. These magnets are so placed. as to aid in the propulsion ofthe wheel, the coilf from the electro-magnet ev on one side being con: nected with the secondary magnet g on the 0pposite side, as clearly shown in the drawings.

The break-piece h la' is formed of two parts, one half of which, h, is a non-conductor, the other half, h', a conductor, connected by means of a. spring, fi, with the opposite cut-ofi" shaft in such a way as to be thrown alternately onto one or the other of two insulated break-pieces, 7c lo', by which the current is nia-de to pass in one direction or the other through either of the coils. One of these break-pieces, k, is connected with the battery by means of the springl through the binding-screw on. The

other break-piece, k', is connected with the opposite binding-screw, n,`by the spring u. One end of each of the two primary blue coils are connected by the wire o with the break-piece or current-changer 7c 7c by means of the spring o. The other ends of thesev coils are alter- Inately connected with the springt to close the current by means of thewires p and qand The auxiliary electro-magnets are aids to the main ones,and their action is too apparent on an inspection of the drawings to require further description.

Having thus fully described my. improvements in electro-magnetic machinery, what' I claim therein as new, and for which I desire to secure Letters Patent, is

1. The employment of induced electricity as above stated in producing magnetism in the secondaryelectro-magnets, to be used as a motive power in. connection with the prime mover, and to neutralize -the secondary cnrrents of the principal magnets formed by the direct current from the battery.

2. The combination of the magnet-changer h h and pole-changer .lc 7a', substantially in the manner and for the purpose set forth.

Witnesses: JOHN H. LILLIE.
