is incorporated in the structure 01 the rotary ill distributor, thereby eliminating the high tension connection between the separate induction coil and the rotary distributor.

I propose to incorporate the induction coil of my ignition system into the removable head on the rotary distributor. By such an arrangement I eliminate all extra connections from the induction coil to the distributor and timing interrupter, leaving only one connection between the energizing battery and the distributor head.

ll propose also to embed the induction coil within the insulating material forming the re movable head of the rotary distributor, and thereby avoid leakage of the high tension cur rent which would otherwise occur where the induction coil is separate from the rotary distributor, llhe construction of my invention also has the advantage of being water dust proof.

I iiirtherpropose to inco within th structure'ot the rotary'dist. ibutor head a sistance in series with the battery circuit to properly limit the current,

My invention is illustrated in the acco'r panying drawing in which Fig. 1 is a vertical sectional view taken through the axis of the combined ignition apparatus;

Figure 2 15 a fragmentary sectional View of the distributor head and part of the rotary distributor taken at right angles to the section in Figure 1 through the vertical axis;

Figure 3 is a view of Figure lt'alren along the line 33.

Referring to Figure l, the rotary distributor and interrupter are housed within a cas ing A which is preferabl formed of cast metal. The lower end of t e housing is provided with atubular bearing extension A which is journaled in a bearing formed on the engine casing or frame as iswell understood, Journaled within the extension A 18 an operl ating shaiit B which is driven from the 1929.

by suitable gearing. The upper end of shaft B is provided with an automatic spark advance mechanism (3 of usual construction, and the shaft extension B carries at its upper end an interrupter cam G and a rotary distributor disc E. The rotary disc E is located in the upper open end of casing A, and is provided with a central contact button F and a rotary contact button G located near its periphery, the two contact buttons being connected together by a suitable connection.

The upper end of casing A is closed by a re" movable distributor head H made of molded balrelite orother suitable insulating material. This distributor head has formed thereon suitable bosses 4, 5, 6, 7 etc., having the usual high tension terminals embedded therein, These high tension terminals are suitably connected to corresponding stationary distributor contacts J located on the bot tom face of the distributor head. Embedded within the distributor head H is an induction V coil 8, the primary winding of which is indicated attic and the secondary winding at 86., The induction coil 8 is provided with a laminated iron core 9 which is also embedded within the head H, and is in the form an inverted U. The magnetic circuitjlor the core 9 is cbrnplete through two arcuate laminated iron core members 10a and 106 located in the upper rim of the casing A, 'llhese core members are preferably incorporated in the casing structure by casting the casing A. around the core members after they havebeenproperlylocated, Referringto Fig ure 3, it will be seen that a considerable gap exists between the endsof the two core 'members, and the ends of core 9 are located adja-,

cent these gaps, The core 9 is of less width than the gaps between the core members 10a and 10?), thereby leaving a desired amount ing is connected to a resistance 13 embedded in the upper central part of the distributor head H. The remaining terminal of resistance 13 is connected to the battery terminal 14, to which is connected an energized bat tery Ba. One end of the secondary winding 86 is suitably grounded, and the other. end is connected to a central contact button 15 located in the lower face of head H and cooperating with central contact button F on the distributor disc E.

Operation of the invention is as follows:

Rotation of the drive shaft B serves to operate the interrupter 11 through the action of the cam D in a well-known manner. This interrupts the primary circuit at timed intervals, and induces high voltage impulses into the secondary winding. Rotation of the distributor disc E effects the successive distribution of the high tension impulses to the diflerent ignition circuits connected with the stationary contacts J on the distributor head. The resistance element 13 embedded in the distributor head serves to properl limit the maximum current which flows in t e primary winding. The spark may be advanced or retarded in the usual manner by shifting the v casing A about its vertical axis by usual control devices connected toextension A on casing A.

From the foregoing it will be noted thatTI have devised an arrangement in which all the elements involved in a battery ignition sys-.

tem (except the battery) are incorporated in a single unitary structurue.

What I claim as new and desire to secure on the flatbottom face of said distributor head.
