sulation 16a likewise insulates the adjacent parts of the 'armature from such current.

)Vith the arrangements above described and the primary and secondary magneto circuits closed, current will be generated during the ignition or the sparking in internal com- 4- bastion engines in accordance with the work required, l provide means for advancing and retarding the armature 3 with respect to the armature driver or pistons of the engine so that the discharges in the secondary magneto lcircuit will be tinied according to the requirements, and to this end l provide the following arrangement :-Upon the magneto shaft el is'loosely mounted a sleeve 2G that is provided with one or moi'e projections or pins 2Ga thatenter spiral grooves et" in shaft il, said projections being shown extending from the bifurcated parts 26? of sleeve 2G, and upon sleeve 26 is mounted an arm 27 Whose hub portion 2T* is so connected with sleeve 26 as to rotate with respect thereto and yet not have lateral motion independent of said sleeve. l. have shown ball bearings interposed between hub 27a and sleeve 26, the sleeve 2li being shown provided with a ball-race 26C receiving balls 28 within a cone er the like 29 cariied by hub 2T and shown held in place by a retainer 3() (see Figs. l and 3). Hub 27.2L is shown provided with pins 3l that extend into slots 32 in blocks 33 secured on the magneto frame (see Figs. 2 and 3) which slots are disposed at an angle to the plane of arm 27, said slots extending in opposite directions as indicated in Fig. 2, whereby as arm 27 is rocked in either direction around shaft 4 said arin and thereby sleeve 26 will be caused to move to .the right or left the desired distance along shaft l by reason of the ball bearings interposed between said sleeve and liub27a. This sliding inotion of sleeve 2() on shaft l will, by reason of the projections 26 of sleeve 26 entering grooves e in shaft ll, cause said shaft to be rotated more or less and thus will adjust the armature correspondingly with respect to its fields and thereby with respect to the point of connection between shaft l and its driving part, such as an engine shaft, cani ll being similarly adjusted with respect to contact 10. rlhe blocks 33 are shown provided with interior concave faces 53 (Fig. 3) ,providing a bearing for hub 2Ta which may rock therein, whereby said arin is held lirmly and supported in addition t'o its support bythe ball-bearings and thereby the arm 27 is kept from twisting, and side :rtl-ain onthe ball-bearings is reduced, thereby also lcsscning friction in the bearings and serving to take the thrust when arm 2l is rocked. Connection is to be made between the driving part or an engine shaft and sleeve` 26 so that shaft 4 of the armature will be free for adjustment with respect to the lengine shaft and yet be rotated thereby, and lo this en d I have shown a sleeve or driving part 35 mounted freely upon shaft 4 and provided with internal grooves 35u that receive the arms or projecting portions 2G of sleeve 2C, in the nature of a longue and groove connection, whereby sleeve 2G may slide along shaft 4 freely with respect to sleeve 35 and maintain rotary connection therewith. A convenient means for providing the groves 35 iii sleeve 35 is to insert within sleevev a sleeve 3G (sce Figs. l and ll) that is provided with slots 35, and to secure said sleeves together by pins 3T. The sleeve is to be rigidly connected with a driver, as with a shaft of a gas engine, whereby the rotation of said shaft will be communicated to the armature It will be understood that a single groove Ll, projeclion 26, arm 2Gb, groove 35, pin 3l and slot inay be used if preferred, or that other suitable means for a sliding and rotative connection between sleeves 26 and 35 may be provided, and also that other means may be provided. than the ball-bearings above described between sleeve 20 and hub 27 for providing rotative yet positive connection.therebctween for causing the rotary and lateral inolion of hub 2T to relatively adjust shafts and'arlnaturc El.

From the foregoing it will be understood that with an engine shaft connected with sleeve 35, to thereby have rotary connection with shaft 4, and with arin 2T in position lo canse retarded breaks in the secondary cil'- cuit of the magneto, that the explosions in the engine cylinders, whose ignitcrs are lo be connected with the distributor contacts 22, 22", 22", 22d in well known manner, will be late owing to lho lact that with respect-to the position of the corresponding piston the break in lhc primary inagncto circuit will be retarded. 'lo advance the spark in the engine cylinder the arni 27 will be rotated 'a suitable distance, ,to cause its pins 3l to travel through slots 32, (in thc position represented in Fig, 3), whereby sleeve 26 will be moved to the right (in Fig. l) and its projections 26, acting willi grooves 4" of shaft 4l, will rotate said shaft iorwardly independently of sleeve 35, and thus iudcpendcntly with respect to the driving shaft, thereby also advancing carin Il with respect to contact lO, whereby the break in the primary magneto circuit will be caused to occur earlier than before, and so on, according to the l i1nit of rotation of arln 27, thc armature and cani being thereby correspondingly adifancedwith respect to the enmove in the direction of said axis, a sliding part connected with said arm, and means to convert the sliding movement of said part into rotary adjustment of the magneto armature.
