The cup 26 is turned by'a lever 60 attached thereto by a rivet 61 for the purpose of advancing or retarding the spark; and the brush 53 bears against a plate conductor 62 which is attached by rivets 63 and 64 to the bottom of a switch case 65 andwhich is insulated from the switch case. The conductor 62 is provided with two contact portions 66 and 67 which are adapted to be engaged by a movable contact 68 mounted on a non-conducting plate 69. Contact 68 is adapted to engage a metal stud 70 which is metalhcally connected at 71 to the switch case 65. Case 65 is metallically connected with the engine frame 2O and is attached thereto by one or more screws 72. rl`he contact 68 is adapted to engage a conductor 73 which is attached to the bottom of the switch case 65 by the studs 70 and a rivet 74. Conductor 73 insulated from the case 65 is connected with a terminal. screw 75.

The non-conducting plate 69 which carries the contact 68 is attached to a slidable locking bolt which is received by a notch 81 in the shank 24. The bolt 80 is guided by a sleeve 82 which is permanently attached by a screw pin 83 to a flanged collar 84 which is soldered or welded at 85 to the switch case 65. The sleeve'82 includes a tubular extension 86 hich extends through a hole 87 in the case 65. A spring 88 is supported by the extension 86 and bears at one end against the sleeve and at the other against the non-conducting plate 69.

The mechanism in operating the locking bolt 80 comprises a key controlled device including a pin tumbler cylinder lock barrel 90 which receives a key plug 91. As this type of lock is known to the trade as the automobile type cylinder lock it is not illustrated in detail, but it will be understood that the turning of key plug 91 by a suitable key will ,danse a pin 92 to be drawn within the cylinder 90. The cylinder 90 is slidingly supported by a sleeve 93 which carries a pin94'eiitering a slot 95 in the side of thecylinder 90. In this way the cylinder is guided during its endwise movements relative to the sleeve 93. Sleeve 93 is permanently attached by screw pin 96 to a case 97 having an outwardly turned flange 98 and an inwardly turned i'iange 99. The flange 98 is attached by screws 100 to a suitable instrument board 101. The screws 100 also secure in position a lface plate 102. The sleeve 93 includes a partition 103 separating recesses 104 and 105. Recess 104 receives a spring 106 bearing at one end against the wall 103 and at the other end against a disc 107 to which a. Bowden wire 108 is attached. The other end of the Bowden wire is attached, as shown in Fig. 2, to the locking bolt 80. When the key plug 91 is turned by a suitable key to withdraw the bolt 92 from a hole 109 in the sleeve 93, the spring 106 will be released to cause the disc 107 and the cylinder 90 to slide toward the left as viewed in Fig. 1. This motion of the disc 107 will cause the Bowden wire 108 to pull the bolt 80 out of notch 81 and will cause the contact 68 to engage the conductors 67 and 73. lVhen this occurs the insulated timer contact 46 will be connected with the ignition coil and the battery. The primary ignition circuit includes, as shown in Fig. 6, a'battery 120, grounded at 121, an ignition coil primary winding 123, a. wire 124, terminal screw 75, conductor 73, conductor 68, Contact 67, plate 62, brush 53, rivet 50, bracket 48, screw 47 and contact 46. The ignition circuit will be completed to ground through contact 48, lever 40, hub 41, stud 42, timer cup 26 and plate 25, shank 24 and grounded engine frame 20. A leaf spring 40a, which urges the lever 40 in a counterclockwise direction in Fig. 5, also provides a part of the ground connection of the contact 45.

The withdrawing of the locking bolt 80 from the notch 81 permits removal of the timer from the engine frame 20 after the nut 29 has been loosened and the screw 28 has been withdrawn from the shank 24. The switch parts within the case 26 are then accessible since the switch case cover provided by the ignition timer cup 26 has been removed. Afterremoval of the ignition timer the nuts 32 may be removed so that ignition timer cup 26 may be removed from the plate 25, if desired. After this is done the nut 42a which screws the timer breaker lever stud 42 in position may be removed so that the breaker lever may be disassembled in order to grind the fiat surface of the contact 45, if desired.

Vhen the cylinder 90 is moved into position shown in Fig. 1 a spring will be released to move the bolt into hole 109 provided by the sleeve 93. l/Vhen this occurs the locking bolt 80 will be moved into position, shown and the switch contact 68 will connect the contact 66 with the contact 70, as shown in Fig. 3. lVhen this occurs the insulated contact 46 will be connected with ground through the following circuit: screw 47, bracket 48, rivet 50, brush 53, plate 62, contact 66, contact 68 and grounded stud 70. Since both of the contacts ot the timer are grounded the timer can not function to cause the ignition coil to produce sparking impulses. When the ignition timer is locked in position on the engine frame no other ignition timer can be substituted, norcan an insulated breaker lever 40 be substituted for a grounded one in order that one of the timer contacts will be insulated. The locking of the ignition timer to the engine frame also renders the ignition switch inaccessible sothat the ground connections can not be interferred with. The locked assembly of parts 65 and 26 Prevents access to the nuts 33 which would permit rellO moval of the timer cup and contact members. Since the cup 26 can not be disassembled from the plate 25 the nut 42a holding the breaker lever l0 in position can not be removed.

The Bowden wire 108 extends through a Bowden wire tube 110. having one end flared at one end over a partition 103 and the other end ilared at 112 against a disc 118 which is received by a recess 114 in the sleeve 82. The Bowden wire and case are enclosed by a flexible hard metal conduit 115 having one end received by the recess 114 and permanently attached to the sleeve 82 and having the other end permanently attached to a sleeve 116. The sleeve 116 has a flange 117 which engages the flange 99 to prevent withdrawal of the sleeve. Moving of conduit 115 sidewise will not affect the position of the Bowden wire 108 so that the bolt 80 might be withdrawn from the notch 81 by movement of conduit 115. If the conduit 115 is moved .sidewise in such a manner as to increase its length the sleeve 116 will slide within the recess 105 toward thepartition 103.
