To all whom it may concern .Be it known that L Jones 'a citizen of the United Stet-r Los Angeles, in the count geles, tote of California. invented new and useful Improvements in Andi solo ing Means for. i iutoniobiles. of which the following is a specification;

This invention relates to a locking device for a gasolene engine of an autonwbilc gasolene motors used for other anrposes.

The object is to prevent starting or open 1 ll El V 3 to avoid removal or theft of an nutomchi Further objects and advantages of t invention will be hronghtout in the specifications. I

Referring to the drawings, Figure 1 shows a front elevation of the locking levice and causing. Fig. 2 shows a plan view of the de- ,vice and a. perforated air muzzle attached, also a small section of the casing cut away to show means of securing the loclr into t casing.

Fig. '2' is a detail in perspective of the valve 6, shown in Figs. Nos. 3', 4c, and 5.

. Referring to the parts in detail; this invention provides an efiective means adapted to admit air under control of lock into the gas supply of an engine; its purpose is to prevent the removal 01. an automobile by an unauthorized person the device is further ndaptnhle for admitting" variable quantities of air into the vapor to reduce its richness for smoother orking and economy. The main object of the invention is to provide simple means adapted to prevent the removal of an automobile, which is accomplished by removal of the key 3, from the lock 2. 'This Will move the valve 6 by the'lever which is attached to the look, from its seat and. leave a. full opening to the valve outlet into tube 8 and into gas manifold 29; the key is then removed and the valve is thereby left open.

The lock 2 is installed in the casing l and held in place by pin 19, on the back of this lock is a. member 5. which is secured to inder i of the. look.

Wl'ien the valve is open and the engine rotating air will rush through the air vents 14 and 15 and perforated muzzle 13 into casing 1 and out through pipe 8 into the manifold and thus prevent the engine operating. The perforated muzzle 13, also air vents 15 and inlet i iare of much importance and are provided and arranged as shown to make it a difficult matter to stop them up, as in such an event, valve 6 would not signify I, much since a liberal amount of air is re- There a variety of known valves and many ways of operating them, and which could be used with some modification in working out a similar improvement. to the applicants device giving substantially the a same result and under control of locking means associated with the key of the lock,

' for instance, a ball valve, a rotary valve,

able parts associated with the lock are ar-' ranged and made adaptable for moving the valve to and from the valve seat, any such combination having locking means and the inner parts associated with and moved by the loci: vl applied to a gasolene motor for supply: air, comes within the scope of the applic s invention.
