Specification of Letters Patent.

Application filed .Tune 17, 1920. Serial No. 389,616.

To all whom it may concern:

Be it known that I, ROLAND P. BERNAR;

DINI, a citizen of the United States, residing at Lakewood, city of Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in carbureter-Locks, of which the following is a specification. This invention relates to a carbureter-c for motor vehicles, and the object of this invention is to provide simple and effective means for looking a carbureter in closed position so that the motor cannot be an unauthorized person.

The nature and advantages of the invention will be better understood when the following detailed description is taken in connection with the accompanying drawings,-

the invention residing in the combination and arrangement of parts'as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein: w

Figure 1 is a side elevation illustrating my improved locking device asattached to a motor vehicle, when positioned to be lowered to lock the carbureter lever when in closed position.

Fig. 2 is a plan View illustrating the carbureter-locking mechanism.

Fig. 3 is a perspective view illustrating the stop member as engaging the carbureter operating lever and the screw by which this" stop member is actuated.

With reference to thedrawings, 1O designates the usual carbureter which is attached to a motor, illustrated by dotted lines at 11. Carbureters of this character are usually provided with a so-called butterfly or disk valve 12 which controls the passage of the carbureted vapor from the carbureter into the intake manifold 13, and this valve is operated by means of a lever 14 through the rod 15 by vehicle dash 16.

Applicant-has provided a simple and effective means for engaging and locking the valve-operating lever in closed position, which means comprises a frame 17 in which is mounted a vertically-disposed screw 18 threaded through a carrying-plate 19, one end of which plate is forked as at 20 to slide on said frame as the screw is rotated.

On this plate 19 I have mounted an arm 21 adapted to be adjusted. longitudinally started by hicle.

whereby when it is desired thereon so as to regulate its projecting length.

This arm 21 has a downwardly-extending end portion 22 to which is fixed a stop boss 23 adapted to fit over and engage the valve lever 14 to lock it ii closed position when the screw 18 is actuated to move the same downwardly, lease thislever the stop may be raised from engagement by turning the screw in the opposite direction.

In order to operate this locking mecha 'nism from the 'dash 16 of the vehicle, I have provided an upwardly extending shaft 24, thelowerend ofwhich is connected to the screw 18 while with a bevel gear 25, which gear is engaged by another gear 26 on the end of the shaft 27, the latter leading through a tube 28 and through the dash 16 to the inside of the ve- On the end of this shaft I have mounted an operating key 29 by the manip ulation of which the screw 18 may be actuated. I

In order to provide means for incasing this operating mechanism and locking the same so that it cannot be tampered gwith'by unauthorized persons, I have provided a metal casing 30 which-has an upwardly-extending portion 31 for inclosing the gears and 26 and also has a laterally-extending portion 32 which has a separate portion 33 embracing the manifold 13 and which separate portion is secured by a lock 34 to the main casing 30. The screw-carrying frame 17 is secured 'to this casing and the tube 28through which the horizontal shaft 27 passes is also secured to this casing as it is threaded at one end 35 and provided with lock nuts 36 both on the inside and on the Patented June 7, 1921.

In order to prevent the key 29 from being door to which is secured I to leave the vehicle and lock the same sothat it cannot be .used, it is only necessary to open the casing key 29 which causes thestop;

When the owner returns'it is only necessary to unlock the casing 39, rotate the key 29 to raise the stopm'ember 23 from engagement with the lever 14 leavin the carbureter free to be manipulated as be ore.

-, The device is'extremely simple and practical in construction and effective in its operation and by its use acar is securely locked against theft.

The foregoing description is directed solel toward the construction illustrated, but desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a device of the character described, the combination with a carbureter having 'a shut-0E valve to the intake manifold provided with an operating lever, of a screwoperated stop-member adapted to be moved to engage and lock said lever in closed powith said valve-lever to lock or release thesame, and means whereby said screw is adapted to'be operated from the dash ofthe vehicle to which the mechanism is attached.

3. In a motor vehicle having a carbureter with ashut-ofi' valve to the intake manifold provided with an operating lever, the combination with a stop-member, a screw positioned to move said stop into and out of engagement with said lever to lpck, or release the same, means whereby said screw may be operated from the vehicle dash, and a casing inclosing and adapted to be locked about said operating mechanism to prevent its being tampered with. In testimon whereof I aflix m signature.
