*Fi'g'ure 11 is a view partly in elevation ,and' partly in section showing the shaft and locking means therefor, and V 1 Figure 12 is adetail View showing the coupling structure 49. v i a p f My improved locking mechanism comprises a suitable frame or casing 1-to be secured to the instrument board 2 of an auto-' 3 mobile, and a dial or'front' plate 8 isemployed and provided with'a suitable opening for the accommodation of the plug or rotatable member 4 of acylinder lock 5, the

body portion of the latter being secured 1- and pressed upwardly by a spring 29 so that its up'perend is caused, under certain within the frame orcasingl. The dial or front plate 3"is'also provided with an opening for the accommodation of the projecting end 6 of an operating shaft 7, the latter being suitably mounted in the frame'or cas The frame or casing 1 has secured there- Figures 8, 9 and 10 are'views illustrating dial lever ing, andthe projecting end 6 of said shaft receives a manually operable leverior 'han upon, a cover plate 9 which carries'two binding

posts

11, 11, to receive

terminalfio wires

12, 12 in the electric ignition circuit.

The binding posts 11 are provided at their-.

lower or inner ends with heads which form contacts '13 for cooperation with contacts 14'onaplate or bar 15, whereby the electric 65 ignition circuit may be opened'as shown in. Figure 6 or closed as shown in Figure 7. The plate or bar 15 of the circuit breaker or switch is carried by "a block or head 16 and the lattercarriesa plunger 17 which normally engages the peripheral portion of a disk 18 keyed to'the-operating shaft 7, y said disk serving to retain the circuit breaker 1 closed under normal conditions,,as indicated in Figure 7. I The disk 18 is providedwith 65 a notch 19v having a beveled wall 20 and a radial wall 21, so that when the shaft 7 is turned in the direction indicated by thea'rrow on Figure 7, said notch will become'dis posed under the plunger 17 and permit said plunger to enter the same, causing the -circuit breaker to open the electric ignition circuit, as indicated in F'igurefi. In order that the heador block 16 and the contact plate or bar 15 of the circuit breaker may be positively moved to the positions shown in Figure 6 to open the electric ignition circ cuit, springs 22 may vbe provided, said springs having "seat's'in sockets in the cover I plate 9 and the block or head 16 as shown in I Figure 1.-

' The shaft 7 also carries a disk 23 having a notch 24, the ends of which form

shoulders

25,26, and diametrically opposite the notch Y 24, the disk 23is provided with a V-shaped g5 notch; 27. -A vertically movable plunger 28 is suitably mounted in the frame or casing conditions,to engage in the notch 24 of disk 0 23 and thus lock-the shaft 7 against turning. The plunger 28 is notched as at 29 to provide a shoulder 30, which is engaged by a roll-back cam 31 carried by the rotatable key-controlled member 4 ,of the cylinder lock 5. The plunger 28.is also provided,

near its upper end, with a shoulder 32 to be engaged by a spring-pressed plunger 33 for the pin-pose of holding the locking plunger 28 out of engagement with the disk, temporarily during the operation of the mechanism. The plunger 33 passes through a guide 34 and carries an enlargement 35, between which latter and the guide 34, a spring 36 is located. The disk 18 carries a laterally projecting lug 37 which, during the operation of the shaft 7, will engage the enlargement 35 on the plunger and move the latter away from the shoulder 32 of locking plunger 28.

\Vhen the parts are in the positions shown in Figures 6 and 8, the electric ignition circuit will be open and the shaft 7, by which the circuit breaker is controlled, will be locked against turning. Under these conditions, the automobile cannot be started, because the electric ignition circuit is open and locked in such condition. In order, however, that the clutch yoke trunnion of the car shall be, at the same time, locked against operation, the instrumentalities now to be described are employed.

The frame or easing 1 is provided with a diagonally disposed portion 1 in which is a diagonal plate 38 on which a slide bracket 39 is movable, a spring-pressed ball or member 40 being employed to maintain said bracketin proper relation to the plate 38. A tube 41 secured to the casing member 1 serves to protect a rod 42, the latter being connected at its upper end with the slide bracket 39 so as tol be moved thereby and the lower endof this rod is connected with a spring-controlled locking bar or member '43 to be moved into locking relation to the trunnion 44 of the clutch yoke, which latter is operable by a pedal lever, as is well understood in the art. The hub 45 of a roll- ;back 46 is mounted in the plate 39 and said roll-back carries a roll-back pin 47 which enters a cam slot 48 in the slide bracket.

A. coupling 49 is pivot-ally connected at one end with one end of the operating'or con trol shaft 7 and at its other end, said coupling is loosely connected with the roll-back hub The coupling 49 comprises a member 49 to engage the roll-back hub 45 and ameniber 49 pivotally connected at one end to the member 49 by a pivot pin 49 and at its other end pivoted to the shaft 7 by a pivot pin.49,.the pivot pins 49 and 49 being disposed at right angles to each other. The operating or control shaft 7 is thus'coir nected with the roll-back hub 45 by means of what, is, in effect, a universal coupling.

It may be assumed that the circuit breaker has been openedas shown in Figure 6 and locked in such position by cooperation of "the plunger 28 with the notched disk 23 as shown in Figure 8, and that the clutch yoke trunnion has been locked by the locking bar 43 as shown in Figure 1. Under such conditions the automobile will be effectually locked against operation. To effect unlocking for placing the car in operable condition, a key 50 will, be inserted into the plug 4 of the cylinder lock 5 and turned to draw the plunger 28 out of the notch 24 of disk 23 and as this plunger reaches its lowest position, the plunger 33 will become disposed over the shoulder 32 of plunger 28 and hold the latter in its depressed position (see Figure 9). The key may now be withdrawn. In order to prevent leaving the key in the lock, where it can be stolen or its number noted for the purpose of obtaining a duplicate, the lock is so located with respect to the lever 8 on the operatingfshaft that the head of the key will be in the path of movement of the lever 8 on the control or operating shaft 7, thus preventing a sufficient movement of the latter toaecomplish the complete operation of the devices controlled from said shaft,,while the key is in the lock.

WVhenthe shaft 7 shall have been unlocked as previously explained and the key removed, the operator will turn said shaft by manipulation of the lever or handle 8, after having depressed the pedal lever which controls the operation of the clutch yoke, to disengage the clutch. As the shaft 7 turns, the lug 37 on the disk 18 will engage the enlargement 35 on the spring-pressed plunger 33 and withdraivt-he latter to release the plunger 28. The releasingv of the plunger 28 will occur after the notch 24 in disk23 shall have passed the upper end ofsaid plunger, and upward'movement of the latter will now be prevented by engagement with the periphery of said disk until ,the

turn and the beveled wall 20 of the notch 19, I '7 will force the circuit breaker to. its'closed position as shown in Figure 7, thus closing the electric ignition circuit,the circuit breaker being maintained closed by engagement of the plunger 17 with the periphery of the disk 18.

During the said turning movement of the shaft 7, motion will be imparted, through the universal coupling 49 to the roll-back cam 46 and cooperation of the roll-back pin' 47 with the cam slot 48 in the slide 39,

will cause vertical movement of the latter until the pin becomes disposed on a dead centerover the axis of the roll-back hub.

Duringsuch vertical movement of the slide,

the locking bar 43 will (through the medium of the rod 42) be raised from interlocking relation with the clutch yoke and the pedal may now be operated in the usual manner to control the clutch.

To move the parts from normal operative position, for rending theelectricignition circuit and clutch yoke and pedal .leverinoperable (as mdicatedm-tl'le drawmgs), the

use of the key is not necessary, it being sufhcient only to turn the lever or handle 8 counter-clockwise to effect a half turn of the shaft 7 and the parts carried thereby and connected therewith.
