I ai full;4 clear` ,andlv Areference heilige nfiade 'to5 the. t 'ing pa rt of f this ispecificatioi `and mani o'lds;o,f internal t nbus son cannot move a motor vehicle under its own power, unless possessed of the key for opening the lock.
Ye are aware that it has been proposed' in the past to provide means for cutting off the flow of fuel to an automobile engine, in order to prevent the stealing of the vehicle, but according to our experience these devices have not been practical and are easy to render ineffective by a person familiar with them. Y
It is our object to provide means for shutting off the fuel to the engine through the intake manifold by means of a valve controlled from the drivers seat of a motor vehicle this valve being such that if the controlling devices therefor are broken it. will seat of itself in position to prevent flow ofgas through the manifold.
lVe accomplish our objects above stated and other advantages by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.
In the drawings,
Figure 1 is a side elevation partly broken away showing oiii invention as applied to amotorvehicle. y
Figure 2 is a detail sectional view taken vertically through the `device as installed. The sectional view is shown broken away to illustrate the locking rod in'two positions the portion on the left with the device unlocked and the portion on the right locked.
.Figure 3 is a central horizontal section taken through the device.
The intake manifold of an internal coin bustion engine is shown at 1 within the trunk of which is set a butterfly valve 2. the same being inserted in any convenient inanner, and adapted when closed to shut ofi" such a substantial portion of the trunk of the manifold that a motor vehicle to be u l' on'asuivt'ableaxi n t the 'valve -isi'fto@insertila"r section 4,. into the T d riveii"'ljvffiiel passing itliroughtvthe manifold "11u i tgperaten@ g i 'lvehas a:shaftavhich is set into iifo'ld trufnkfland supports rtliezvalve One method ofins'e `ting tij iik". iii ivliiclifithe :valjvejdisk iscniounfed, l vthe pin orf shaft set at one end ina small so'cke't drill/edwintheiiiside; oftlietruiik the pin' beiiigflsetf, t rough r a hole bored through all .of/thesection;jifistfbelow k,the slot. llie iiise'rt section will :be-welded into place.
ifiebe'irig. a'dj acent; the.; valve.. saidA casing being welded into place. A pinion (l oii the outer end of the valve shaft is engaged wit-hin this casing b v a rack 7, mounted and guided iii a tube 8 extending from the casing or housing 5.
A spring t) is provided suitably hung iiiside of the manifold. and engaged with the butterfly valve to pull itto closed position` should it be otherwise released.
The rack is engaged and operated h v ay flexible shaft l() extending through the tube 8 which is heavy, casesliardeiied tubing and has a small passageway to the dash 12 of a motor car. 0n the end of the flexible shaft is lock 11 which has two dogs 13 and l-t therein undercontrol of suitable springs 13, 14" which tend to piisli them outwardly.
` A key 15 acts to control the dogs b v means of any form of lock which will pull theminwardly when the key is revolved.
The lock dogs engage behind the ribs 1G, of a casing 17, in which the lock slides, this casing being connected to t-lie case-hardened tube. To close the butterfly valve the lock is pushed in. and when it is desired to operate the car the key is used to release the lock dogs. 7e mount a spring 18 within the casing 17 behind the lock 1l, which acts to thrust the lock oiitwardly,to open the butterfly when the dogs are released. The tension of the spring 18 is niucli greater than that of the spring 9. so that the moment the dogs 13 are released by turning the key. the spring 18 pushes out the locking rod and opens the valve, and this is against the tension of the spring 9.
The operator may thus lock the car against theft(` which involves a thrusting in by him of the movable lock member on the end of the shaft. A thief will have to break the lock or the case-hardened tube to get fuel to the engine. This he will not be able t0 wmv Y sing ze :ist made part of, the insert, the
do, but if he did manage to break the tube or tear it away the sprintr 9 would close the valve. y
Thus unless the thief take the intake manifold to pieces he will be unable to get gaseous fuel to the engine, which amounts to practical assurance that he will not steal c the vehicle under its own power.
It is contrar;y to most traffic laws to lock the wheels of a vehicle against movement, either by transmission or external locks. It is ineffective to merely lock shut the gasoline pipe to a vehicle, because it can be quickly short cut by rubber tubing. It is also stated to be simple to shunt out of the way an ignition lock to a vehicle. All of these devices do not require the engine to be taken to pieces. and to successfully drive away a car equipped with our lock will necessitate dismounting the intake manifold or breaking,T it to pieces, which would disable the car.
Having thus described our invention. what we claim as new and desire to secure by Let- In combinationwith the trunk of all intake manifold, a butterfly valve located therein and inaccessible from without the manifold when the same is mounted on the engine, spring means acting to maintain the but-tery closed, a flexible shaft and hard metal casing therefor, operative connection between the Shaft and the valve to posif tively operate the same in all movements thereof, a lock casing connected to the shaft casing, a lock mounted on the end of the shaft and movable in said casing. said lock being?r so arranged as to close the buttery being stronger
