LGCKING VALVE;
"Application fiie cca 28 1921. Serial. Np. 41mm.
o allwkom itmuiy concern:
e it. kno n that I, WALKER MAns i L a citizen Of the United States, and a resident of thecity of Springfield, county of Clark,
and State of" Ohio, have invented 'lcertain lockingva-lve of the type shown in my .co-
pending application for; valves filed sepv tember 19,1919, Serial No. 32,4,994Land for automobile attachments filed March 29,1920,
Serial No. 369,596, which is adapted to be interposed between;the carburetor and the,
' intake manifold of an internal combustion motor particularly automobile motors, and which provides an effectivemeans forfpre- (venting j unauthorized use of. a motor or vehicle by cutting off the fuel supply to the motor.
My present invention consists in ii-nprovemerits in this type o't'jlocking valve which greatly simplifies its construction, so that it is more positive in operation and can be .manufactured more quickly and cheaply;-
Other objects will appear hereinafter.
The invention consists in thecombinations scribedand claimed. e I I i The invention will be best understood by reference. to the accompanying drawings forming part of this specification, and in which, i

ear err-ice.-
"Fig. 8 is an end view of; a manifold;
partly in section, showing my modified form of invention forming apart thereof. The nventmn is designed for use. with automobile motors and is preferably interposed between the intakelmanifold X;
and the carburetor ".C of such a motor as shown in Fig. l. Theinvention is soconstructedjthat it may be applied between the carburetor and intake manifold on either side of the motor. The valve comprises apreferably cylindrical casingl open atone end and closed at the other and having oppositely disposed tangential fianges 2 and?) on its peripheries and asuitably; shaped port ,4 extend ng through the flange 2 and adapt-.
ed to communicate with the intake manifold X of the motor when the flange 2 is secured .to a similarfiange on said manifold Xh The casing also, has an oppositely disposed port 5 extending through the flange 3 and adapted to communicate with the outlet of a carburetor when the flange 3 is secured to a similar flange, on said carburetor. The, casing 1 also. has a radially extending shollowboss6 on its. periphery intermediate the flanges 2 and 3, and near theopen end of the casing. In the bore of the boss, 6 is mounted a pin 7 which'is normally projected into the casing l for purpose hereinafter described by means of an expansible sprmg 7 mounted thereon, the
7 lower end of the spring abutting against the flange 9 on said pin 7 and the upper end of the spring; abutting against thethreadcd threaded counter bore 6 in. said boss (5. The
outer end of the pin 7 may have a cord (not cap, 11 which is preferably cast, with a bore shank 1O of a. nut adapted to engage; a
12 and a counter bore 13. Into the bore12 is. inserted acylindrical lock housing 14: which contains a lock of a standard. con,-
struction, the outer end ot said housingcomplete and effective means for preventin being provided with a flange 15 adapted to fit'nicely into counter bore 13 so that the surface of the cap or disc 11 will be smooth and unbroken except for a keyhole into which is inserted the key for, moving the valve into inoperative position as hereinafter described. The housing lt is exteriorly threaded on its inner end to permit a milled locking nut 16 to be screwed tightly thereon securely fastening the housing 14 to the disc or cap 11. The housing 1% preferably has a rotatable post 17 mounted eccentrically on its inner face. The post 17 has a shoulder 18 and a reduced portion 19 through which is tapped a pin 20. Between the shoulder 18 and the pin 20 is mounted a collar 21. The collar 21 preferably has a radially extending pin 22. Attached to the pin 22 is one end of a helical spring 23 which is mounted on the post 17,
' the other end of said spring being attached to a small lug 24- on the inner face of the housing 14 beside the post 17. The collar 2l also preferably has ears 21 which 'en gage the pin 20 to prevent the helical spring 23 from unwinding, but at the same time permitting the pin 22 to be oscillated on the post 17 The pin 22 engages and actuates a slide 25. Said slide 25 consists of a curved plate having a hollow boss or socket 2-6 on its convexed surface intermediate its ends adapted to receive the pin V The slide 25 able key and held in this position until the pin 7 is disengaged from. the notch 28; the helical spring then operates to close the slide '25. As before stated therap or disc 11 carries the lock and slide actuating members, the slide being a separate piece but adapted to be engaged with the pin 22 before the mechanism is inserted. into the casing 1. In addition I provide a preferably U shaped member 28"which helps to retainthe cap or disc 11 in the casing 1 and at the same time forms a stop for the slide This member has one of its bent arms forked as shown at 29 so as to straddle the milled locking nut 16 and is adapted to be secured in such position by means of pins driven into the disc 11 thus providing a the nut 16 from moving. The opposite arm of the J-shaped member is adapted to abut against the wall of the casing 1 and is pro vided with threaded bores which are adapted to receive threaded screws 29' tapped through the abutting wall. The connecting arm 30 serves as a stopto limit the movement of the slide 25 when urged into closed position by the spring 23.
The flange cap or disc 11 is preferably cast slightly larger than the opening in the casing 1 so that when, the cap carrying the parts is to be inserted thereintoit will have to be driven or forced, thereby firmly securing the cap 11 in the casing." Thearm 30 is then secured to the opposite wall by means of the screws engaging sockets in said arm as above described and the heads of such screws may be chipped off and touched with a brazing iron, if desired. When assembled the slide. 25 on the pin 22 is held in retracted position by the spring actuated pin 7. When it is desired to lock the device by closing the inlet opening of.v
the manifold the spring pin 7 is withdrawn from the notch 28 in the slide 25 at which time the helical spring 23 forces the slide to locked position completely covering the inlet aperture of the manifold. The slide when in closed position abuts against the member 30 so that the slide cannot be forced past the aperture. The valve is then i in closed locked position and effectually prevents the unauthorized use of the motor or vehicle. b-en it is desired to again use the motor the person having a key fitting the particular lock of the valve will insert the key into the lock and rotate the post 17 and slide 25 away from the intake opening.
until the notch 28 in the slide is engaged by the spring pin 7.
In Figs.=7 and 8, I have shown a modification of my invention. which is of value in that the valve is rendered even more in accessible than any construction previously described. In this form of locking valve, I preferably employ intake manifold X cast witha housing 31 thereon, as shown in Fig. 8. The housing 31 is similar in all the respects to the casing 1 except that it is' cast integral with the manifold. A boss 6 is provided to carry the spring releasing pin 7, and the disk 11, carrying lock housing 1%, locking nut 16, post 17, spring 23, collar21, arm 26, stop 30, and the other parts of the locking mechanism are the same as before described.
hile I haveillustrated and described the preferred form of construction for carrying my invention into effect. this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the construction set forth,
and modifications as come within the scope of the appended claims.
