AUTOMOBILE PROTECTION DEVICE.

. Application filed. May 17,

To all whom it may cancer Be it known teat I, GEORGE ConnouRNn, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful improvementin r'iutomobile Protective'Devices, of which the following is a. specification.- v 1 My invention relates to automobile pro tective devices, and it has particular relation to devices for controlling the-supply of fuel for gas engines.

One object oi? my invention is to provide a protective device of such character as to effectually prevent unauthorized use of an automobile.

The second object of my invention is to provide an arrangement in which theyparts of the mechanism for rendering a gas engine operative and inoperative are removable and interchangeable whereby the engii' e-can not be operated in the absence of one of the parts.

lflumerous devices heretofore for the purpose of preventing ti e unauthorized use or theft of automobiles. Such devices generally comprise member which has two positions in one of which the engine rendered inoperative. Protective devices may, however, be adjusted to their operative positions in case the lock is broken. The parts necessary for the operation of the engine are not removed therefrom.

According to the present invention, I pro vide two independent, removable and interchangeable parts for controlling the manifold of a gas engine. One of these parts or the vent shutter is provided with an opensize to that of the enother or blind shutter when it is substituted it effectually prevents engine by obstructing nine manifold. The has no opening and for the first shutter, the operation of the the engine manifold.

In the accompanying drawing, Fig. 1 is a side view in elevation, of the carburetor and manifold of an automobile engine with my invention applied thereto.

Figs. 2 and 3 are respective side and end views of the shutter-case.

Fig. i is a view, partially in section and partially in elevation of the shutter-case and the vent shutters, the latter being partially withdrawn.

Figs. 5 and 6 are respectively side and edge views of the vent shutter.

have been proposed,

1921. Serial Na l-70,321.

Fig. 7 is a side view of the solid or blind shutter.

Referring to the drawing, a manifold l of a usual gas engine is connected to a carbu- 6 retor 2 of any suitable or usual type. The opening or passageway for connecting; the carburetor to the manifold is controlled by a protective device 2 comprising; a shuttercase 3 'which is inserted between the adjacent ends of the manifold and the carburetor outlet. Each. of these associated parts is provided with laterally extending flangese having suitable openings for the reception of bolts 5. The bolts are provided with nuts 6, lock washers? and with pins8. of hardened steel, for securely and permanently retaining the nuts 6 in operative,position. The. pins 8 prevent the removalof the. nuts 6 in the absenceof special tools for such purpose The shutter-case 3, shown in detail in Figs. 2, 3 and 4c, is provided with an opening 8 which corresponds in size to that of the carburetor outlet and the manifold. The device 3 is provided with a laterally extending slot 9 of wedge shape for the reception of the one or the other of two shuttcrsnvhich' may be termed, respectively, the. vent shutter 10 and the blindshutter 11. The vent shutter 10 is provided with an opening the diameter of which corresponds to that of the opening' 8 and the openings in the associated parts. The blind shutter 11 has no opening", and when it is in position, the open ing in the manifold is effectually closed. Each of the shutters provided with a hole. 13 by means of which padlock or other suitable locking device may be inserted for the purpose of preventing its unauthorized removal.

The operation of my improved protective device will'be readily understood from the foregoing description. When it is desired to operate the car, the vent shutter 10 is inserted, as illustrated in Fig. 1, and isloclred in position by a padlock 14 to prevent the unauthorized tamperin'g with, and the consequent disabling of, the machine. When the parts are assembled in the manner described,

the engine operates in the usual or normal remain in the m achine, but is retained in the possessionof the driver. sible for the machine to be operated by any person except the driver without breaking the lock, removing the blind. shutter 11, and

closing the end portions of the slot 9. This procedure is difiicult of execution because all the parts are constructed of highly tempered and hardened steel.

It is practically impossible, also, to so close the openings or the slot 9 as to render the mechanism operative. in addition, it will require considerable time and the use of considerable force to destroy the locking device and to take such StQ'JS as. are necessary to render the macliiin-e operative. The

danger of detection is so great that it is entirely unlikely that an attempt will be made to either use the machine without the authority of the owner or to attempt thethett of the same.

It will-be noted that'l providean arrangement in which the necessary parts for the operation of the machine are entirely removed .from the latter when it is desired to prevent its unauthorized use. I

A devlce constructed in accordance with my invention maybe manufactured at low cost. It is of such nature that it may constitute a standard part of any and all automobiles. It may also be incorporated in the structure of automobiles at any t1 me during their operation. The above and other advantages will be apparent to those skilled in" the art to which my invention appertains;

I claim as my invention: I

l. A protective device comprising a memher for conducting fluids having a lateral opening and a pair of independent removable members that cooperate with said opening to respectively permit only or prevent only'the passage of fluid through said con- "ducting member. said removable members be ing non-rotatable relatively to said conducting member;

'2. A protective device comprising a memher for conducting fluids having lateral opening and a pair of independent remov able members that cooperate with said open ing torespeotivel'y permit only or to prevent only the passage of fluid through said con-' ductmg member, said members being interchangeable.

A protective device comprising a mem= ber-' for conduct ng fluids having a'lateral' opening" and a-pai'r of independent inter changeable" non-rotatableshutters that coop It is now impose being so arranged that it may erate with said opening to respectively permit or prevent the passage of fluid through said conducting member.

4. A protective device, comprising a memberior conducting fluids having a lateral opening and ;a pair of independent removable members that cooperate with said openlng to respectively permit only, or to' prevent only the passage of fluid through said conducting member, one of said removable mem- 5 bers'being so arranged that it may be locked in operative position i 5.'A protective device comprising a memher for conducting fluids having a lateral opening and a pair of independent interchangeable non-rotatable shutters that cooperate with said opening to respectively permit or prevent the passage of fluid through said conducting member, one of said shutters be locked in operative position.

6. A protective device comprising an engine manifold having a pair of lateral open ings extending therethrough, a pair of independent and interchangeable shutters removably associated with said openings for permitting or preventing the passage of fuel through said manifold according as the one or the other shutter is in position in said openings, said shutters being. nonrotatable with respect to said manifold.v

7. A protective device comprising an en movably associated with said openings for" respectively permitting "only "or preventing-J only the passage of fuel through said manitold according as the one or the other shut ter is in position in said openings, one of saidshutters'having an opening whereby 1001; may be inserted. 1. 1
