member of the ignition controlling switch, which has a square central opening in which the stem '25 of the handle 12 is adapted to fit. The portion of the stem within the casing and adjacent to the face plate is square in cross section and receives the. locking disk 26, see Figures 1 andG, said disk having a square opening through which the stem 25 passes before passing through the oscillatory member 20. The disk 26 is provided with a notch 27 in its outer margin, said margin also having an elongated notch 27' in which a relatively fixed projection 27 may loosely engage to limit the oscillatory movement of the disk, stem 25 and handle 12. The stop 27" projects from the inner surface of the face plate, as best shown in Figure 1.

1n locking position the recess 27 receives a locking tooth 29 which projects into the aperture 30 of a slide member 31 which is preferably formed to encircle the disk 26.

The aperture 30 is elongated to allow a movement of the slide sufficient to carry the tooth 29 into or out of the recess 27, said slide being preferably shaped substantially as shown in Fig. 6. The said slide member is also provided with a second hole or aperture 32, to accommodate a disc 33, eccentrically carried by the barrel 34 of a suitable lock 35, which is mounted within the casing or housing 10. The said eccentric disc 33 is provided with a projection 36, adapted to bear against the marginal wall of the aperture 32,

" which marginal wall is preferably provided with a curved notch terminating in shoulders 37, adapted to be engaged by the said projection 36, whereby rotary movement of the disc 33 may be limited. The end of the slide having an aperture 32 is guided or limited as to lateral movement by a projection 32' which is struck up from the face plate, as shown in Figure 4, lateral movement of the slide in the opposite direction being limited by a disk 38 through which extends the stem 39 of the lighting switch handle.

7 The arts are so designed and constructed that w on a key is inserted in the lock 35 and the barrel 34 thereof turned, the rotation of the eccentric disc 33 will, through its engagement with the slide member 31, cause the latter to be reciprocated to bring its tooth or projection 29 into and out of the notch 27 to engage and disengage the disk 26, thereby locking or unlocking'the ignition lever. A bearing plate or disk 40 also having a square aperture to receive the stem 39 is of sufiicient diameter to form a seating for the disk 26 and the associated end por-' tion of the slide 31. This disk 40 is pressed against the disk 26 and slide 31 by a disk shaped member-41 having multiple arms 42.

-The central portion of the oscillatory member 20 bears against the disk 41 and is held in pressure relation thereto by a cotter pin.

or detachable key 44. The multiple arms 42 will of course yield slightly under pressure, whereby when the cotter pin is inserted, all of these interior parts of the switch will be bound to the inner surface of the face plate in pressure relation to each other. The notch 27 is located at a substantial distance from the axis of the operating piece or stem 39, wherebythe locking operation is performed at an effective radius. The disk 26 cannot rotate independently of the large square shank or operating piece 39 which not only has an extended bearing in the disk, but the disk itself is clamped between the face plate and the bearing plate 40 and therefore held against distortion.

The locking mechanism will thus be seen to be extremely simple, and it can be quickly and cheaply manufactured from stamped sheet metal. It thus results that while an ellicient locking means is provided whereby the unauthorized movement of the ignition switch may be effectively prevented, at the same time the cost of manufacture is maintained at the lowest possible point.

\Vhile one form of the invention has been illustrated and described, it is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore it is not wished to be limited to the above disclosure except as may be required by the accompanymg claims:
