"said contact being in electrical engagement with a' wire'24 of the generator or magneto circuit. rllhus, when the ignition yswitch is opened, the circuit of the generator or inag-y netorisgrounded -to'still further interfere` with operation of the motor. i'

`By proper movement of the permutation locking means yet to be described, the arm `19 may be moved'lat'erally so that its contact 16 rests unon the fixed contact 8 anc. said l. arin .may then be moved Vlongitndinally to the position shown in Fig. 2. During this f movement, the contact 16V slidesupon the contact 8 and the free end of the arm 19'engages with a spring detent or the like 25 Vwhich isiixedly mounted within -the casing.,

the armbeing provided with a .shallow seat 26 into which the detent25 sneps. It will thus be seen that the detent or shoe25 holds the arin19 in such a manner as to veectively retain the contacts 16 and 8 in engagement lwith each other, at the Sametime holding the arm 21 ofi' Vof thecontact 23Vso thatrthe generator or `the like may operate (see VFi`g.l`2). f Y i lVhile Vthe swinging arin 21 maybe mount-V edv in any desired mannerfl prefer to pivot the samey upon a rigid stub 27 which extends froni one sideof the casing 1. I also prefer to provide this 'casing with at least one internal stop 27 to limit'thermovement ofthe arin 21 in one direction as seen in Fig. 2, and if desired another stop may be employed to restrict the movement of said arm in the opposite direction. rlhe free end of the arm 19, in the preferred form of construct-ion, is provided with a laterally extending lug 28 having a notch 29, whereby said arin may interengage with the notched .outer fend ,30 of a lateral plate 31 which isl mounted on .the inner rend of the operating shaft 32 which is secured tothe knob 3; Plate 31. is preferably threaded `and keyedv iiponv the shaft 32A as indicated at 33 inY Figs. 5 and V7 and in the present showing, the plate in question is provided with an inwardly extendingV hub 34 rotatably received in a stub shaftY 35 integra-l with one side of the casing and parallel withthe stub 22,. serving as bearing `meansfor theshaft32. Rotatable upon the stub shaftl 35 arerthe'tumblers 36 ofthe locking. mechanism, :said tiimblers having notches 37 ywhichare adapted to be alined as wliereby to receive an arm 38 which extends rigidly-fromV the arm 19. V'Thus,whereas this Y arm 38 normally rests upon the edges of the tumblers36 as seen in Fig. 1, the .moment the notches .37 are alined, the arm 38 mayinove into said'iiotches, thereby permittingv the contact 16 to engage therrcontact 8. 'A spring 39 is' preferably Venfipl'oyedtov shift thearin 19 so that its lateral arm 38 will engage the notches 37. and whenzthe parts stand'inthe position shown in Figfl, this springisof course under tcnsionin readiness to act. As soon as lthe ar'inshifts under ftliefaction of this spring, the armi19..operatively.engagesV the plate/31 as seeirin Fig'. 3, whereupon turn;

`ing'of the knob 3V in the proper direction, will cause said plate to move arm 19 longitudi- Ynally into engagementv with vthe shoe or detent 25 as seen in lFig. .2 thus holding the.`

contacts 16 and 8 in proper engagement with 4each other and retaining the arm 21 "away Vfrom the contact The machine is now in condition lfor operation, biit it'will be seen that asv there is no meansprovided except the knob 3 for alining the'notches 37 of the tumblers 36, only authorized persons can in the present showing, each of the tumblers 37 is ,provided on one side with: an arcuate spacing flange 40 'whose ends co-act with a radial lug 41 on a collar 42 which is free l, to rotate'on the stub 35, one of these collars be# ing ,positioned within each flange 4()V asrwill be clear by reference toFigs.` 7 and9. The side of each tumbler 36 opposite the flange 40, with one exception, is provided with ya laterally-extending proj ection 43V and' .this pro'- .fplace theV switch in condition for4 operation. i

jection of Aeach tumbler extends into the.

space within the flange 40 of ythe next adjacent tumbler for co-action with Vthe lugl41 of the adjacent collar 42 (seeFigs. 7 and9). The lug 4l on one of the endmost tuniblers 42, is in theY path of a projecting pin Yorthe like 44 carried by plate31 as shown for in- Y stance in vFigs. 7 and 10. It will thus be seen that turning of the plate 31 through the instrumentality of theV knob 3; and shaft 32,Y will cause the pin 44 to rotatetlieadjacent collar 42, thereby causing the lug 41 ofthis collar to Vcoeact with the flange 49 of the next adjacent tumbler 36 to turnY this tuinlbler. The tumbl i'v in question in turn operates the nextadjacent collar 42 and the lat-` tei' turns the next tumbler., Thusby turn-v ing the ,shaft in a predetermined manner all of the tuinblers may be positioned Vso that their notches 37 aline, permitting closing of f the switch16-8 and .opening of the'switch 21-23 (see Fig. 2). v

To prevent thetransfer of movement from onel tumbler tothe next byv friction, after proper setting, l provide a plurality of veryY l thin brake rings45l which are suitably interposed between the several tuinblers,V said iso ' 1 brakeY rings being'fixed upon the stub shaft-.i

The 4severaltumblers and the. collars 42 are -held in `proper relation withthe Y brake rings45 by means of a U-shaped re-v :tailler Y free end of the-stub shaft- V35 and is receivedl 48 4(see Fig.- T13) :which straddles the in a peripheralv groove 493e thereof.

ARadi-al set# Y "screws 54 threadedthroughY the outer-seoV Y tions 50 y A2()` Vof thetumblers normally engage the inner sections l so as to lock the* two against relative turning.' By loosening Athese set-screws,lhowever, the inner sections 5l which carry thelanges 40 may be adjusted f .within the outer sections- 50 havingk the notches-37.
