DISTRIBUTER STRUCTURE.

Be it known that I' ARTHUR A'rwArnB I KENT, a citizen of the ilnited States, resid- "ing in Ardmore, county of Montgomery, and

circuit of 'State of Pennsylvania, have invented certain new and useful lmprovements in Distributer Structures, of a ecification.

y invention relates to; distributor structure such as employed in thehigh tension 'gnition apparatus for internal combustion engines; t

It is common in index-internal combustion engines vto employ in association with a a distributer ele-v ment, rotated in definite relation with theengine, stationar contacts or terminal connects ed, respectivey, to theispark plugs of the ,difi'erent engine cylinders and supported on or carried by a detachable member, generally a cap adapted to house and 'in'close both the "distributor and I the timer for interrupter structure the support or. cap carrying also 7 a centrally disposed contact connected with the source of spark" producing energy'and engaged y a c ntact "9 he: "r t r dtributer'.

It has beenfound,particularly when the contact on therotary distributer is a resllient or yielding one'spaced from the distributer,

thatin replacing the support or Ca ra;

bringing it into operative position, the-su port or; cap may be moved laterally while p its-fi r pe a p s tl n and in so' going the'central contact on the In 'accordance with" my invention, this contact maybe separated orspacedfrom the ipart 'distributer, and so nrev'enting conflict or engagement with the captermlnal or other, 1n bringingthec'ap to its Qp01'itt1YeiPQ sition.

My invention 'residesin features of structune and combination hereinafter described For an illustration of some of the various forms mymvention may -take,reference is to be had to the accompanying drawing, in

Referring to Figs. 1 and 2, his abase' or supportto which is attached, as byhook springs2, the cap 3, referably of molded p v pon the base 1 within thecap are mounted timer or interrupter to control the "prima circuit of an inductlOIlCOll. "The movab e contact is indicated at 4 and is carried upon an arm 5 actuated by cam 6 to control the co -action of the movablecontact t with the stationary contact. The cam" 6 is formed upon or secured to the cam shaft '7; driven, as well understood in the art, in definite relation with the main shaft of the internal combustion engine Whose ignition is controlled by the earn 6.

I 110 a distributer em odying a modification The upper end 8 of the cam shaft extends *into a 'recess 9 in the detachable or'removable 'dis'tributerymember or block 10, the latter ;hav1ng atthe bottom of the recess 9"the,

transversely extending rib 11, intelgral with member-10, engaging in an offset s ot in end 8 of the cam shaft, whereby the'shaft 8 in rotating rotates "the member 10 with it.

Carried by the member 10is the yielding or resilient contact12,;asofspring,steel or 100 the like, secured at its one end adjacent the'out'er end of the member 10 and extending substantially radially toward its center and upwardly away therefrom, whereby its free end is spaced from member 10 and re- 10$ 56 tn uter, though: leaving the distributercom 13threadedinto the metallic bushing or in- 1 10 sert 14 molded in the distributer block 10. The same screw may secure to the member 10 the metallic brush or terminal 15, whereby the contact 12 and member 15 are in electrical connection with each other.

In the center of the cap 8, that is, substantially co-axial with the shaft 7, is a metallic bushing or insert 16, with which is adapted to be connected one terminal of the source of spark producing energy, for example, one terminal of the high tension secondary winding of an induction coil. On the lower end of said bushing 16 is the projecting terminal or contact 17 adapted to make contact with the distributer contact 12, the contact 12 rotating with the shaft 7 while maintaining contact with terminal 17 At equal distances from the center of the shaft 7 and suitably angularly or circumferentially spaced are the metallic bushings or inserts 18 molded in or carried by thecap 3 and terminating within the same in the distributer terminals 19, past which the aforesaid brush or terminal 15 rotates, allowing to pass to each in succession spark producing energy delivered to the spark plugs of the engine cylinders by conductors communicating with the bushings or inserts 18.

'hlolded integral with the member 10, or otherwise suitably provided as hereinafter described, is an upstanding boss or lug 20 having the under cut or recess 21. The boss or lug 20 may originally have no recess 21, or such recess may be formed in the molding operation. To mold the recess 21, however, is more or less difiicult, and itis preferred, therefore, that the boss 20 be originally formed "complete, and the recess 21 thereafter cut or formed by any suitable means.

The boss 20 and its recess 21 are so positioned that the free end of the spring contact 12 extends into the recess, as indicated in Figs. 1 and 2, the lip 22 limiting the distance away from the member 10 to which the contact 12 may spring. lVhen the distributer is isolated, as in Fig. 2, that is, when not in cooperative position with the cap 3 and its terminals, the spring 12 normally engages the under side of the lip 22.

By this construction, or its equivalent, the distance to which the free end of the contact 12 may spring away from the member 10 is limited, yet that contact -may yield toward the distributor member 10, as indicated in Fig. 1, while co-acting with the terminal 17 carried by the cap 8. The contact 12 cannot spring away from the distributer block 10 to such distanceas might or would interfere with attachment of the cap 8 to the base 1 in the operative position illustrated. With the contact spring 12 extending to too great a distance from the member 10, the cap or some part carried thereby in being brought to operative position would engage the spring 12, and forc ing the cap to position would cause harm either to the part of the cap engaging the contact 12, or the contact 12 itself would be distorted, bent or otherwise undesirably affected.

In lieu of molding the limiting structure integral with the member 10 as above described, it may take the form of a separate piece or insert of metal or insulating material molded in the member 10 in suitable position.

This modification of my invention is illustrated in Figs. 3 and 4, where the member 20 is an insert of metal or insulating material molded in the member 10 and having or forming a recess 21 below the lip 22.

Or the distributer 21 may have molded therein a hole or recess into which there is later inserted or secured a plug of metal or insulating material suitably formed, for example, having a recess and lip as above described.

means on said member limiting the separation of the free end of said contact therefrom. i
