A .ALF'QNS H. NEULAIID, OI FRANCISCO, CALIFORNIA.

To all whom it may concern:

Be it known that I, ALFONS H. 'NEULAND, a subject of the Czar of Russia, and a resident of the city and county of San Francisco and State of California, have invented a certain new and useful Ignition and Lighting Apparatus, of which the following is a specification.

My invention relates to dynamo electric machines and particularly to an apparatus for providing i tion engines an also for provid ng electrlc current for lighting or other pu'r oses. The

i as

apparatus is particularly adapte to .be used on internal combustion engine driven vehicles and eliminating the lighting feature, may be termed a magneto.

An object of the invention is to provide an ignition device of simple construction in which the high tension coil is stationary.

Another object ofthe invention is'to provide an ignition device in which a comparatively large amount of winding space is provided for the high tension winding. j

A further object of the invention is to provide an ignition device which also generates a low tension current for lighting or geous features, some. of" which, with the foregoing, will be setforth at length in the following description,- where I shall outline a :--in full that form of the invention which I:

have selected for illustration in the drawings. accompanying and forming art "of the present specification. In said rawings I have shown one specific form of the device of myinvention, but it'is to be understood that I do not limit myself to such form,

since the invention may be embodied in a plurality of forms without departing from the invention as expressed in the succeeding claims.

Referring to said drawings:

' Figure 1 is a cross section of one form of apparatus of my invention taken on the line 1.-1, Fig. 2.

Fig. 2 is a longitudinal section taken on the line 22,Fi .31. f Fig. 3 is a dlagrammatic representation of the windings of the apparatus: and their.

associated circuits. I

Magnetos that are now on the marketimay .be dividedinto two type there a revolving" armature carrying general types. In one high tension collecting member. other type of'magneto, an inductor arrangement'is employed in which the high tension coil is stationary, but the mechanical complications are such that the manufacture of ition' for internal combus- 1 windings t The magnet may consist of a single magnet, butpreferably consists of several mag-r nets arranged side by side with their like IGNITION AND LIGHTING APPARATUS.

the high tension windingwhich possesses a small amount of winding space,

only ma ing insulation difficult and requirlng a In the the magneto is very expensive. Neither of these types of magnetos iscapable of successfully furnishing a low tension current for lighting without interfering with the high tension ignition current. T In my pre have been overcome and my'present device sentrinvention these difficulties comprises a simpleconstruction having a stationary high tension coil, which by reason of the-large space available therefor, makes the winding and insulation thereof cheap and simple. In addition, my present device provides a low'tension Winding for -'generating current for lighting purposes, which is arranged in electrical'space quadrature with the high tension winding, so

that it does not interfere with the current in 'the high tension winding. Itis to be understood that when the device is to be used low tension lighting current winding may be omitted and I do notlimit myself to the combined lighting and ignition features.

The device comprises. two stationary, prefiouit. Rotatably arranged between the pole pieces, is a magnet 9, preferably permanent, which upon rotation \causes a reversal of flux througlh poles contiguous. The magnets arehe'ld together by suitable bolts whichrseat in the end 'lates 12, or brass, aluminum or other? suita 1e nonmagnetic material, and the-end plates 12'are secured to stub shafts 13" and solely for the purpose'ofignition, that the I erably laminated, pole-pieces 2 3 opposing the laminated core 6 and the,

v 14, suitably journaled in the casing 15. The 1 magnet'fmay. be of "such lengthas to directly v face the pole pieces 23,-but I-' prefer to- .provide the ends of the magnet' with lam sion ignition winding inated pole shoes 1 6-17 to facilitate the rapid shifting of the flux from one side of the end of the magnet to the other. As the magnet rotates, the flux is rapidly reversed through the laminated coreandthe ignition windings thereon. The primary or low tenis provided with a breaker 18 preferably operated by a cam 19 on the stub shaft 13. Atthe time of breaking the primary ignition winding, the magnet is approximately in the position shown in Fig. 1 and the fiux, at the moment of break, rapidly shifts from one pole tip to the'other, thereby quickly reversing the flux through the ignition windings, and it is the purpose of the laminated pole shoes to facilitate this rapid shifting of the flux. In accordance with present practice, the low tension and high tension ignition windings 7 and 8 are preferably connected in series and the spark plug 21is connected across the high tension winding and the breaker across the low tension coil. 7

When the device is to be employed to generate also a low tension current for lighting or other purposes, a longitudinal slot 22 is provided in the middle of each pole piece and a loW tension lighting coil 23 is arranged in the slots, in the present instance the coil being formed in two sections. This coil is out of phase with the ignation coils. lVhen the magnet is in the vertical position shown, none of the flux will pass through the ignition windings and all of it will traverse the li' hting coil and when in a horizontal position, the flux traverses the ignition windings and not the lighting coil.

For this reason, the generation of the igni- 7 tion circuit is substantially unaffected by the. condition of the lighting circuit and fjections onsaid pole-pieces,

vice versa. The short circuiting of the primary ignition current andthe generation of the high tension ignitioncurrent will not materially interfere with the lighting current.

I claim:

1. In a dynamo electric machine for ignition and lighting purposes, a rotatable magnet,'a plurality of pole-pieces facing the magnet, a laminated core connecting said pole pieces, a high tension ignition winding on said core, and a low tension winding on the pole-pieces arranged in electrical space quadrature to said high tension ignition winding.

2. In a dynamo electric machine for ignition and lighting purposes, a rotatable mag net, pole-pieces facing said magnet, a laminated core connecting said pole-pieces, a high tension ignition winding on said core, said pole-pieces being provided at their cen-: ters with slots and a 10W tension winding arranged in said slots.

3. In a dynamo electric machine for ignition and lighting purposes, a rotatable I magnet, pole-pieces facing said magnet, proa laminated core connecting said pole-pieces, low tension and high tension ignition windings arranged on said core, said pole-pieces being provided at the center of their faces with longitudinal slots and a low tension Winding arranged in said slots.

In testimony whereof I have hereunto set my hand at San Francisco, California, this 13th day of September 1916.

ALFONS H. NEULAND.

In presence of- H. G. Pnos'r.
