State of. Indiana, havewinvented a certain new and useful Electric Generator; and l do hereby. declare that the fgllowin 1s a full, clear, and exact"dsci "itlon; thereof, reference being had to the accompanying drawings, in which like numerals refer to' like parts. 6

The object of this inventlon 1s to improve the construction of magnetos or electric gen- It has been used in connection with magnetos adapted" for sparking purposes in combination with explosive engines.

One feature of the invention consists 1n forming a core with laminations extending longitudinally .of the armature shaft,an d securing on-said. core wings formed of laminations extending at aright angle radially from the core whereby heating between said wings and core will be avoided as the magnetism will pass at all times longitudinal y of the laminations or layers.

Another feature of the invention consists in providing three-way Wings at each end of the core, S11d;WlIlgS being in staggered position with relation to each other. In combination with the foregoing a pair of pole pieces are provided so that there will be a coaction at every 60 degrees of revolution of the core. When a wing atone end of the coreisin coaction with a pole piece, a wing at the'other end of the core is in, coaction with the other pole piece and with this arrangemen-t one pair of wings comes in coaction with a pole piece almost immediately after the preceding pair has left the ole piece so that there areas many actlons durin each revolution of the core as it is possib e to have in such a device. And thus, the eiiiciency of-the machine is increased.

Thefull nature of the invention will be understood from the accompanying drawings and the following description and claims.

- Iii-1 dean 1 r isf'the base, and '11 the 1 pole pieces which *in 1 {are arranged degree'sapart and in Fig. 3 are arranged: :degree'sfa; artgwith inner surfaces SllbStill'ltia'l'ly as ide"a's"th'e wings 12 ofjthe ears. Magrit e" 13 are mounted in connection with fsa'id pole ieceslf Between said p pieces the arrest is winding 14 is mounted i and within said winding'the longitudinal core 15 is located, it being secured on the arma-' ture shaft 16. The core consists of layers secured longitudinally on the shaft by rivets 17 that pass through said layers and the shaft 16. The wings 12 are likewise formed of. laminations or layers surrounding and secured upon the core 15 and extending radially or at a right angle therefrom into proximity with the pole pieces. This manner of constructing the core is convenientand economical as the layers of the wings can be punched out of metal so as to have the desired number of wings, three as herein shown, and then the plates or layers are slipped over the portion 15 of the core and secured in place by rivets 18 or in any suitable manner. There are three wings at each end of the core located equidistant apart circumferentially and the wings at the tWo endsof the core are staggered with relation to each other,.so'tha t there are six wings 60' degrees apart, and each wing is nearl 30 degrees W1d8,. so that very soon after one set v of Wings leaves the pole pieces, the succeeding pair reaches the pole pieces and no time is lost and as many actions are caused as is possible in such a machine.

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

1. In a generator, the combination of a pair of poles, a rotor cooperating with said poles and provided at opposite ends with a plurality of wings angularly separated from each other and relatively angularly displaced so as to be broughtinto successive coaction with the poles in opposite magnetic relations, said rotor being laminated in its wings in lanes substantiall at right angles to the axis of the rotor an in its intermediate portion being laminated, substantially parallel with the axis of the rotor, and a suitable winding surrounding the rotor be tween the wing members.

2. In a generator, the combination of oppositely magnetized poles, a rotor cooperatmg with said poles and provided at opposite ends with radially extending portions adapted to simultaneously cooperate with the poles in successive magnetic alternation, said rotor being laminated in its radial extensions in planes substantially at right angles to the axis of the rotor and in its intermediate portion being lai'ninated substantially paral: lel with the axis of the rotor, and a suitable Winding surrounding the rotor between said radial extensions.

In a generator, the combination of a rotor eonuxrising a central portion and a pair of wing members at its ends, each of said wing members comprising three radially extending Wings spaced 120 degrees and the wings of one of said members angularly displaced relative to the other, the merlinl nm-tion of said rotor being laminated EDllllRD 'l.
