MAGNETO WITH WATER-TIGHT CASING.

Application filed March 6, 1918.

To all whom it may concern:

Be it known that I, GEORGES AURJ JLIEN CHAILLIEY, a citizen of the Republic of France, residing at Chemin du Vallon, Lyon St. Clair Caluire, Rhone, in the Republic of France, have invented new and useful Im movements in Magnetos with Water-Tight Casings, of which the following is a specification.

The object of the present invention is a magneto of special construction, it being specially designed to afford an absolutely watertight apparatus.

This result is obtained by the special arrangement of its cylindrical field frame which carries pole pieces cast together with the same. The different orifices in this field frame (oil holes, screws for contact disks) are covered by suitable rings. The invention is clearly set forth in the accompanying drawing, which represents an example of the invention, and relates to a method of practical execution of the same, showing the advantages and the special features.

Figure 1 is a longitudinal section of the magneto designed according to the invention.

Fig. 2 is a cross section of the same.

The present magneto comprises a cylindrical field frame f (Figs. 1 and 2) which carries the pole pieces 1 and 2 (Fig. 2) cast together with the same, also a magnet 3 (Figs. 1 and 2) this being a portion of a cylinder, and an end cap 5 (Fig. 1) having two bores, one adapted to receive the ball bearing ring 6 and the other to receive the cam ring, 7

On the collector side, the field frame is threaded internally at the same diameter as the field bore, in order to receive the support 8 of the ball-bearing 9. Three holes are provided in this support in order to bring the lubricating oil to the ball-bearing surface. A boss 19 on the top of the frame opposite the collector serves to receive the high tension brush holder 10.

The lower base 11 of non-magnetic material serves to attach the magneto as may be desired either upon a flat base or a round base, using in the latter case the surfaces A and B.

The contact break used with these magnetos is reversible, and to provide for running the magneto in one direction or the other, all that is required is to shift by the Specification of Letters Patent.

Patented Apr. 6, 1920.

Serial No. 220,731,

in order to uncover the single oil hole 5 which is used for lubricating the two bearings 6 and 9. An oblique hole 22 in the cap 5 brings the oil to the bearing 6, and a groove 16 is made obliquely in the frame in order to avoid the boss 19 and to facilitate the flow of oil, and this groove is covered by the magnet. This latter arrangement serves to bring the oil to the bearing 9 on the collector side.

The magnet fits upon the field frame without the use of any attaching screws, and it is held in a fixed position between the flange of the frame and the end cap 5.

A tight passage is also secured for the shaft 17 by the use of a small felt-covered disk 21 which presses upon this shaft and the inner bal1-bearing ring.

It will be observed that the present design allows of machine work in standard types in a Very practical manner as all the parts are entirely lathe-turned.-

It is understood that the present design is not intended to limit the possible arrangements, and that while remaining within the limits of the invention, all necessary special modifications may be made either as regards details or the proportions, of the entire apparatus. 1

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An ignition magneto containing, jin combination, a cylindrical field frame provided with a flange and having a threaded bore on one side and a cylindrical portion on the other, a ball bearing mounted in the threaded bore of said frame, a cap with two bores mounted on the cylindrical portion of the frame, a ball-bearing disposed in one of the bores of the cap, a contact break disk mounted in the other bore of the cap, a cylindrical magnet fitted on the field frame between the flange and the cap, and a lower basewith cylindrical sides and "flat bottom ."attached to said magnet, substantiallyas bore on one side and a, cylindrical rounding the cap, screws connecting said 7 outer ring to the contactbreak disk and extending through-the said transverse slots, a cylindrical magnet fitted on the field frame between the flange and the cap, and a lower base with cylindrical sides and flat bottom attached to said magnet, substantially as described and for the purpose set forth.

3. An ignition magneto containing, in combination, a cylindrical field frame provided on the outside with a flange and having a threaded bore on one" side and a cylindrical portion on the other, a ball bearing mounted in the threaded bore of said frame, a cap with two bores mounted on the cylindrical portion of the frame,

- a ball bearing disposed in one of the bores ofthe cap, a contact disk mounted in the other bore of said cap, the field frame being provided in its'outer surface with a spiral 'groove extending to the first mentioned ball bearing and the cap being provided with a conduit extending to the other ball bearing and with an oil hole in communication with the spiral groove on the field frame and with the said conduit, an angularly adjustable I ring provided with an opening and adapted -to cover the said oil hole, a cylindrical magnet fitted on the field frame between the and a segmental cylindrical magnet fittin over the frame and pole pieces and clampe between thesaid peripheral flange and the cap. f

5. An ignition magneto comprising in combination: a gcylqindrical non -m-agnetic frame having a eripheral flan e, pole pieces secure y he d in said cy indrical frame, a cap secured to one end of the frame, a segmental cylindrical magnet fitting over the frame and le ieces and-a base, the magnet and the we eing clamped between the said peripheral, flange and the cap. 6. An igmtionmagneto comprising in comblinationlr a cylindrical non miagneltic frame havin a ripheral flange, pole pieces secure y he (1 in said cylindrical. frame, acap secured to one end of the frame, a segmental cylindrical magnet fitting over the frame and pole pieces and a base having a flat bottom and cylindrical side faces, the magnet and the base being clamped between the said peripheral flange and the cap. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
