ELECTRC ISI'RBUTER.

To 'eli whom it ma.' concern .f

Be itknown t at I, Louis J.. FLINT, a citizen of the United States, residing at South `lZVhitley, in ltheycounty of Whitley -and, Sta-te oflndiana, have invented. a certain new and useful. Improvement inglillectric Distributeraof which thefollowing is cipall object the a full, clear, concise', and exact description,

referencebeing had to the aceompanyingv drawings, forming a part of this specification.y V

A further object resides in the particular.

arrangement and combination of parts hereinafter described.

The articular devices shown, described and claimed herein are shown and described but not claimedI in my co-pending applications Serial No. 581,915,- filed September 18,

1910, and Serial No. 627,646, filed May l?, 1911. l v 1 `In the accompanying 'draWingsFigure 1 is a vertical longitudinal section showing my improved distributor fzs-actually mounted in connection With a magneto device for electric ignition purposes, this ligure 'being identical with Fig. 1 of application -No. 581,915'above mentioned; Fig. 2 is a cross section on. line c-c of Fig. 1'; Fig. 3 is a vertical, longitudinal section of a second form ofA my device also shown as mounted in connectlon With a magneto and inter-L Yrupter, this figure being taken from Fig. l

of my application No. 627,646.; Fig. iis a cross section on line JC-f4 of Fig.` 3; and Fig. 5 is a perspective View showing the method of assembling the conducting elements of the form -shovvn in Figs". 3 and 4c.

Referring more particularly to the draw-A ings, 1 is a metal rod formin the center of a revolving structure which 1s the movable element of my distributer. Surrounding the rodV 1 is an insulating sleeve 2. Surrounding the sleeve '2 in turnisv a'metal sleeve 3.

Surrounding the sleeve 3 is a second layer of insulating materiali forming a bushing e,

on the Aoutside of Which-is a second metal .sleeve or cylinder 5." At kthe rightrof the '-rod. 1: and vthe sleeve 3 is mounted `a disk Specification.' of Lettere Patent., Appxieauon mea January io, isla seran un. amera 'or plate 6. Further to the right of the plat v, ther described.

6 is" a similar plate 'Z'. Mounted between these plates 6 and 7, is the armature 8 of the magneto. The plate 7 connects with a shaft Q which iis-provided With suitable ball bearings andi's driven 4from a shaft 10. by gears as shown. -At the left of the revolving structure is shearing 11, While at the left end of vthe shaft is the revolving part of the interrupter 12. l'lo the-left ofv the, interruptor 12 is a stationary cap 13 Within which is-mounted a condenser 14:. The-magneto generator, the driving l:mechanisrn, theinvterrupter and the condenser form no part ofl this invention and Will-not be furtherlde-` scribed.` The revolvingy elements: are all' mounted upon ar brass boxl of'square cross section which is suitably mounted upon a base member-16. t the left end of the box 15 is' 'a perforated iron member*v 17 which.

closes the end ofthejbox proper and Within which the bearing l1 is mounted'. Suitable permanent magnets for 'exciting they armature are mounted upon the exteriorl ofthe box 15, but as they have 'nothing to do with- `the invention claimed herein, are not fur- Mounted upon the centr-'al longitudinal vline ofthe boer 15 is a bodyof insulating material 18 which is fastened to the box by a screw 19 and to the'member 17 by a second screw 20. Cl-he insulatingA material v18 projects through aperturesvin` the top of the box 15 as shown at 21.- The projections 21 are reduced andl provided'with'additional projections'22'.c Mounted Within" the insulation 18 are metallic sleevesQB- hav-ing" sockets or'the reception ofthe l'conductors Qd'which lead' to the yseparate explosioncylinders.-v ,Sleeves 23 also arelprovided With pinsQ projecting through laperturesin the parts 21 and Q2. 'lhe cylinder -jisprovided with a series-of projecting arms 2,6,-A one for each-ofthe' pins 25 and as the sleeve revolves vthese armsA are brought into contact with the pins 25 forthe purpose of producing a sparkinthe proper cylinder. Mounted on the ends of. the bushing 4 are two insulating `disks 27 which protect the cylinder 5 iroxzn thedirt and oil which might Work its tray along'from the -bearings. n 1

lt will be understood 4that one end of the high tension winding `of the arn'laturel is connected to ile@ ieylilidl- 5 and vthat 'the' other end ofthe 'high ltension winding connected to earth s'o that when contact is made between one of the arms 26'and one of the ins a spark will pass from the spark p ug to the middle of the cylinder. It will be `observed that Iny improved distributer is entire] lincased and completely ro- In the orm shown in Figs. 1 and2 tie complete device i has a rectangular outline but this, of course, is not essential.

Referrin more particularly to Figs. 3 and 4, it wi l be observed that the same general combination of driving means, armature, distributer and interrupter mounted to ,revolve together is there shown'as was shown inFi s. 1 and 2.l The construction of the' distri uter is, however, specifically diiferent. In this form we have an terior rod 50 vmounted in the center of the rotating element, an insulating sleeve 51 surrounding the rod.50, and a metal sleeve 52 outside of the insulating sleeve 51. Surrounding the metal4 sleeve 52, however, is a 'body of in- I u l n A ridges 54 have a continuous circular outline lbeing a threaded connection between the sulating material 53, which is cast in one piece and is provided with circular lridgesas 54, as well as with oil shields 55 all cast integral. The revolving contact points are shown at 56 in Figs. 4 and 5, and are formed as rojections on rings 57, the rings 57 bein embedded in the rid es 54. As indicate however, in Fig. 5, t e rings 57 are made separate from the remainder of the device and are provided with apertures 58. In manufacturin the revolving element the pin or 4rod 59 is paced in the mold.l The rings 57 are then t readed on to this rod by means of the apertures 58. As shown in Fig. 5the -apertures 58 are placed in different positions on the differentvrings, so that the pro'ections 56 shall be spaced the proper angular distances from one another as required by thenumber of cylinders in the engine. The insulatin material 53 is then cast around the rings Xing them solidly in place. Asindicated by the dotted lines in Fig. 4, the

and the projections 56 come flush with the surface of the ridges. The stationary parts 0f the device shown kin Fig. 3 are also somewhat dilferent from those shown in Fig. 1. In Fig. 3 the box or casing 15 is provided with a series of apertures, as in Fig. 1. In Fig. 3, however, we have a series of separate insulating plugs 60 which project from the exterior into the interior of the casing, there lugs and the. casing, as indicated at 61.

ithin the plu 60 are mounted conducting sleeves 62 provided with sockets for receiving conductors which shall lead to the engine cylinders. The lower portions of the lsleeves 62 are provided with pins 63 upon which are loosely mounted conducting caps 64. The caps 64 rest on the surface of the 'ridges 54, in order to make contact with'the pro'ections 56 at proper intervals, the plu 60A aving extensions 65 within whic t e caps 64 are mounted..

It will be understood that one end of the 'high tension winding of the armature is connected to the rod 59 or to one of the rings 57, the other end being earthed.

H'aving thus described my invention, wlat I claim is:

1.
