E. Roue, citi- .;'zenm the .United States, residing at Florence, inthe countyof Codington and State- 'ofzSouth Dakota', have invented certain new fand' useful' improvements.. in Locksy of Whichthe'ffollovving is' a specification.

The'p'resent invention relates to new and "useful vimprovements in safety locks for vautomobiles .such asy are employed in guard-A ing against'the.. operatingof the machine by' 'an unauthorized person. I Aniobjiect isto provide yieldable means for-','hol'ding thev bolt in locking relationto the clutchpedal, :such yieldable ',mean's'being of su'icient strength to prevent 'nth-ebelt' from jarring out of place as by the vibration or the engine, but being so engaged with the bolt thatvit Will give Way to permit the 4bolt vto be Withdrawn when the key is properly applied.

' An object of equal importance With the foregoing; is to construct the locking device with. such regard to proportion, number and arrangement of parts that it may be cheaply y manufactured, Will be durable and eilicient u re appended heretovand form apart lot'ythis in its action, andmay be readily applied to any standard form of automobile Without requiringanyv material changes in the construction thereof.

The above and additional objects are accomplished by such means as are illustrated in the'accompaiiying drawings, described in the ollowingspeci-cation, and' then more particula'rly pointed out in the claims, which application.'

4In reduction "to practice', it has .35,

that 'the form of this invention illustrated inA the drawings, andreferredl above description as thepre'ferred ment is the most eflicie'nt and practical'g`-y realizing that `the-'conditions .concurrentwitr the adoption `of thisfdev'ice'willnecessarily? vary, it is desirable to. emphasize the :fact

that various minor changes in details struction, proportion and arrangementlf parts may vbe' resorted to, 4when requirjefdyv without sacrificing anyl of the advantages of this invention, as defined in' theappend ed claims.

The opening inthe clutch pedal is prefere ably ormedun such a manner las toalinement withthe locking-boltl whenthe clutch is thrownout or .in inactivev pbsitiol;4

This permits locking' oit'l the vehicle .while theengine is running, land avoids any 'possilbility of accident .through the throwing in of. Vgears Vby' unauthorized -.persons, even though the engine is running.
