Mac-Nara Specification of Letters Patent Patented May 14:, 1912.

- Application filed March 25, 1911. Serial No. 616,965.

To all whom it may concern:

Be it known that I, ALBERT Sornumr, a citizen of the United States of America, residing at Flint, in the county of Genesee and State of Michigan,-have invented cer' tain new and useful Improvements in Magnetos, of which the following-Visa specification, reference being had therein to the ac companying drawings- This invention relates to magnetos, and

it has for its object the improved construction of the current-distributing, member thereof, as will be hereinafter described and defined in the claims.

'thereo Fig. 3' is'a front view of the current-distributing member with its driver;

. Fig. i is a side view of the same; Fig. 5 isa face view of the driver, per 86, and Fig: 6 is a frontview of the distributcr per 86.

Referring to the drawings, the magneto comprises an armature shaft 10, the magnet 11 and a distributing mechanism disposed in a casing 12 at one side of the magnet, and provided with a central bearing-member 13. A tie rod 14 extends from the member 13 to the outer face of a cooperative casing 15 disposed at the other side of the magnet, both casings being thus held firmly in place.

The armature-shaft 10 has a pinion 16 (see Fig. 2) in engagement with an insulated intermediate 17, which actuates a gear 18 journaled on the bearing member 13 above mentioned, through balls 19. This gear 18 constitutes the driver for the distributing member which is normally rigidly secured thereto, but may, by virtue of my improved construction be readily removed therefrom when desired.

In its preferred form shown, this distributer consists substantially of a plate 20 made of insulating material and having a portion ofits central portion inclosed by a flange 21 which forms a central pocket 22.

Disposed within this pocket, and firmly se-' cured to the plate 20, is a metallic plug 23,

and housed within the upper portion of the .fiange 21 is a bearing;bushing 24 adaptedto receive a slidablegstubbrush 25, made of carbon orthe like and having at its diamet:

ricallyopposite sides apertures 26 (see Fig. 6) which are adapted to receive the bent- ALBERT SCHMIDT, OF FLINT, MICHIGAN, ASSIGNOR TO CHAMPION IGNITION COM I over ends 27 of a two-arm resilient wire spring 28, these ends 27 passing through slots 29 (see Fig, t) formed inthe station ary bushing 24-. r

The central ioop' portion 28"of the spring is rigidly secured to the plug 23, the entire organization being such that the spring will serve not only as a means for normally pushing-the brush 25 outward into the position shown in Fig. 4, but alsoas a'conductor iter electrically connecting said plug and rush.

Seated within the end of the casing 12, is a contact-disk 30 which is made or insulating. material and has a number of the number of cylinders and the rotatiw speed of the engine shaft and of the disductor 35 embedded within the contact disk 30 and connectedwith a metallic center 36 spaced contact-plates 31, proportionate to which in turn'is in permanent metallic contact with the plug 23. As the brush 25 is revolved, electric current is supplied to the several contact-plates 31., which are respectively connected with binding posts 37 from which conductors may lead to the spark connected plug 23, spring conductor 28,, and,

brush 25, all assembled as a unit which may be bodily attached to or detached from the driving gear 18. To this end the gear 18 has a pair of dowel-pins 4:0 fitting into apertures 11 of the insulating plate 20. A third pin or stud 42 also held in said gear18 has a perforation 43 within which is plvotally supported the straight arch-portion, 44, of a bow spring comprising a pair of resilient arms 45. The free ends 45 of these arms are hentoutward (1'36 Figs. 3 and 5) and adapt-ed to as sprung into notches or grooves 1-6 found in the studs it being understood that headed studs will answer the same urpose. The bentover. ends 45' of the. ow-spring serve as finger pieces whereby the bow-arms may be sprung inward to free them from the studs 40, and the bow-spring may then swing forward and downward (see dotted lines a in Figs. 3 and 4), whereupon the insulating plate 20 will be free to be removed.

It should be understood that many changesmay be made in the particular con- "struction and organization of my improved device,'without departing from the spirit of "the invention.

I claim:

nism comprising a contact disk having an insulated contact plate, a rotatable member of insulating material, a brush movable ,in said member, and a two-arm bow spring detachably secured on the face of said member for moving said brush into cooperation with said contact plate.

2. In a magneto, a distributing mechanism comprising a contact disk having an insulated contact plate, a rotatable member of insulating material, a. brush movable in said member, and a two-arm spring detachably secured to the face of said member, en-

gaging opposite sides of said'brush for moving said brush into cooperation with said contact plate.

3. Ina magneto, the combination with the:

armature shaft, of a distributing mechanismcomprising a driver operable by said shaft, a pair of pins on said driver, an apertured plate of insulating material on said pins, a bow-spring engaging said pins and detachably holding said-plate thereon, and electrically conneoted'contacts carried by said late.

4. In a magneto, the combination wit the armature shaft, of a distributing mechanism comprising a driver operable by said shaft,

a pair of pins on said driver, an apertured plate of insulating material fitted on] said pins, a bow-spring pivotally attached to said driver and engaging said pins and detachably holding said plate-thereon, and electrically connected contacts carried by said plate. p

In testimony whereof I affix my signature in presenceof two witnesses.
