To all whom it may concern:

Be it known that I, DEXTER EDWAnn lVIouL'roN, a citizen of the 'United States,. and a residentof Pierre, in the county of Hughes and Stateof South Dakota, have invented a new and Improved Timer and Distributer, of" which the. following is a full, clear, and exact description.

Myinvention relates, to timers and dis 'tributers and has for its object the provision of a simple, compact, efiicient and inexpensive device the parts of which are so related that the same can be easily inspected.

or cleaned when necessary and the relation of which'lparts is such that they require little attention, andthe same are self-adjustable. r y W ith-the above andother objects in view,

the nature: of which willmore fully appear as the description proceeds, the invention consists-in the novel construction, combination' and arrangement of parts as herein fully described, illustrated and claimed.

1 In the accompanying drawings, forming part of the application, similar characters ofreference indicate corresponding parts in all theviews. I

Fig. 4 is a similar section on line 44:, Fig. 2; Fig. 5 is-a perspective view of the timer; and Fig. 6,.that of the distributer.

{Referring to. the drawings, 7 represents the driving shaft. Fitting over one end of the shaft is an .insulated sleeve 8 of con- .densite; Said sleeve 8 is provided with a closed end 9 which rests on thesaid end of' V the shaft. Adjacent the open end, the sleeve are fitted 'metallic' contacts 11 extending from the lateralsurface through the sleeve 8 is provided with a collar 10 into which "itocontact with the shaft 7. Said contacts 11 aresymmetrically disposed on the lateral surface of the collar 10. There are four of said contacts and they are at rightangles .to each other, as can best be seen in Fig. 4;.

A groove 14 is provided in the closed end 9 of the sleeve 8 which registers with alining openings. 15:.provided in the frustoconeshaped member .-13.

face of the frustocone-shaped member 13 ,carrles a metallic contact strip 17 which has a portion 18 thereof located in the smaller base of the member13 and extending to the center of the same. The sleeve 8 carries a ring 19 located between the collar 10 and the member 13. This. ring. constitutesa spacer and also a'locking for the pin 12.

Covering the above-described structure is a dome 20 which comprises a frustoconeshaped recess21 of similar'convergency as the frustocone-shaped member 13, so that a snug fit th'erebetween is obtained. The cone shaped recess terminates with a cylindrical recess 22 of a diameter sufficiently large to accommodate between the collar and the r wall of the recess a swinging ar1n23. One

end of the arm is pivotally mounted within shaped, while the lower part is cylindrical.

Mounted in the top of the dome and in a connection with the secondary wire from the coil. This binding .post has an interior flange 28 engaging the portion 18 of the metallic strip 17 with which it is main-- tained in contact by a. resilient member 32. Contactp'oints 20 are provided in the frustocone-shaped recess2l of the, dome 20. The annular distance between the said contacts is 90. The exterior surface of the dome metallic strip 17'when the frustocone-shaped member 13 is rotated through the medium of the shaft 7. Thedome 20 is prevented from rotation during the rotation of the shaft? .by its connection with means for controlling the dome on the frustocone shaped member'13, which means, although not shown in the drawings, are adapted to be connected to an extension 31 provided on the dome,-.as shown in Figs. ,1, 2 and 3.

V the axisthereof is a binding post 27 to form I loo The dome covering the revolving .parts of the device protects the same from injury, and also prevents oil or other material from entering and lodging between the dome and the revolving parts and thus interfere with the perfect distribution and interruption of the current. It will be noted that the primary to the coil is controlled by the contacts 11 within the collar 10, which periodically come in contact with the roller 25. The secondary, of the coil coming through the post 2'? is conveyed to the plugs of the engine from the posts 30. The relation between the metallic contacts 11 within the collar 10, the metallic strip 17 within the frustoconeshaped member 13, and the contacts 29 is such that the primary and secondary currents are properly timed thereby.

Although the disclosure made shows the frustocone-shaped member and the sleeve made of separate pieces, the same can be made of a single piece if desired. The dome, which is funnel shape, as can be seen from Fig. 1, if desired can also be provided with a closed bottom.

ilthough the above described and illustrated device is mainly intended for the Ford automobile, it can be as efliciently used with any other four-cylinder, four-cycle engine; and while I have described the principle of operation, together with the clevice which I now consider to be the best em bodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.

I claim:

1. In a timer and distributer, a rotatably mounted sleeve of insulating material, symmetrically disposed contact members carried by said sleeve, a frustocone-shaped insulating member on said sleeve, a metallic contact strip on the lateral surface of said frustocone-shaped member extending to the central part of the small base of said member, an insulating casing having a cone-shaped recess fitting snugly over the frustoconeshaped member, symmetrically disposed contact points carried by said casing and adapted to be engaged by said strip on the lateral surface of the frustocone-shaped member when the same is rotated through the medium of the sleeve, a binding post carried by said casing and in engagement with the extension of the strip, a second binding post associated with the casing, a swinging arm carried by said post within the casing, means for maintaining said swinging arm in contact with the sleeve, whereby the contacts carried by the sleeve will consecutively engage said arm, and means for turning said casing on the frustocone member.
