ALVE LOCK.

Application filed September 4, 1924. Serial No. 735,768.

To all whom it may concern:

Be it known that I, ADOLPH Mains, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in a Valve Look, of

which the following is a specification.

This invention relates to an improved valve lock, and more particularly, in a preferred embodiment thereof, is designed for application anduse in connection with mo: .tor driven vehicles whereb the floizs or supply of fuel, such as gasoline, for the op 'eration of the motor, may be prevented and the possibility ofv theft or operation of .the

a minimum. 1 a

It is another object of my invention to provide a valve lock for the above purpose, which can be easily and quickly appliedto vehicle by unauthorized persons, reduced to the modern motor vehicle without necessitating' any radical structural changes therein, and which,'when applied, cannot be detached or removed from its operative position.

In a simple and practical embodiment .of

the device, a tumbler pi'n cylinder lock is associated with a rotary valve slug-interposed inthe fuel supply line, sa' lock having a key receiving barrel mounted for1ro tary and axial movement and said barrel and the'valve plug being provided with coacting means, whereby when the barrelfis rotated to 'a predetermined. position and then "shifted axially, it is automaticallyzconnected with the valve plug whereby the latter may be moved to its open or. closed positions. e v I With the above and other objects injlview,

the invention consists in the improved ,=?$1Ye-- lock, and in the form, construction and relative arrangement of its several; parts as" will be hereinafter more fullydescribed, il'- lustrat'ed in'the accompan ing. drawing,-and"i I ya'sj-to, frictionally engage the beveled faces *of the collar withcthebeveled surfaces of subsequently incorporate iniilzthepsubloind claims. I -1 In the drawing wherein, 1 11M. a simple and desirable construction'and' ;iflwhich similar reference charactersdes'ig nate corresponding parts 'throughout,-=t several views: Figure 1 is a sectional view showmglmy improved lock valve arranged in the fuel supply pipe of a motor vehicle;

Figure 2 is a sectional view taken on the line 2-'2cof Figure 1;

Figure 3 is a' view. similar to Figure 1 showing the valve in open position;

Figure-4 is a plan view;

Figure 5 isa detail end "elevation of the barrel of the cylinder lock; and Figure 6 is a similar view of the rotary valve member.

Referring in detail to the drawing, wherein I have shown the device mounted and arranged in operative position on the board B above the accelerator pedal of a motor vehicle, the valve body 5 which may be of any preferred form or shape, is provided absolute fluid-tight connection between the pipe sections and thenipples 7, I provide each pipe section in s aced relation to itsend with an annular ange or collar of V shape form in ,cross-section, said collar having theoppositely beveled surfaces 9. Each nipple .7 is provided with-- an internal shoulder 10 againsti which the end of one of the pi e'sections 8 seats, while one of the beveled aces.9 of the collar on said ipe section seats against the chamfered or ev-,

.eled surface 11,on'the end of said nipple. The nipple- 7 .is exteriorly threaded to re; :ceiyeithe internally threaded coupling memher-12, one end of which is provided with an internal beveled face 13 for engagement tviththe iother beveled face 9 of the collar lim thei pipe section 8, Thus vit will be ap-' p ai'ent 'that. when the coupling member 12 Is screwed up tightly upon vthe nipple 7 so the -con ling member and thenipple 7, a fluid-tig't connection is secured,

which is intersected centrall of the valve body by the chamber 15 whic receives the The valve body- 5 is formed-with a longi-' tudinallyextending fluid passage or bore rotary valve plug or member 16, said valve member having a port 17 extending transversely therethrough in the plane of the passage 14.

The valve chamber 15 at one 'of its ends opens into a recess 6 formed in the upper face 6 of the valve body. A cylinder lock the sleeve 19 being formed with an out- Wardly projecting beveled flange 22 to coact with a beveled face formed on the plate 21 at one side of the opening therein. This plate is engaged in the recess 18 of the valve body and permanently fixed thereto by means of a plurality of driving screws, indicated at 23. The other or upper end of the lock cylinder 18 has an out-turned flange 24 formed thereon extending within the plane of the face plate 20.

The cylinder 18 is formed with the usual eccentrically located opening 25 therethrough, to receive the barrel 26, said barrel being provided with the customary slot to receive the key 27. This barrel and the lock cylinder are likewise provided with the usual spring-pressed sectional tumbler pins 28 with which the key 27 co-operates.

As herein shown, the barrel receiving opening 25 at the upper end of the lock cylinder is diametrically enlarged as at 29 to mov'ably receive an annular flange 30 on the end of the barrel and which permits of the axial or longitudinal movement of said barrel relative to the cylinder. The wall of the barrel is provided with a U-shaped slot 30 therein having circumferentially extending arms at its upper and lower ends. A pin 32 fixed in the cylinder 18 projects into this U-shaped slot and limits the rotary and longitudinal movements of said barrel. At its lower end the barrel 26 is formed with a diametrically extending rib 33 which is adapted for engagement in a slot 3 1 formed in the upper end of the rotary valve member 16, as will be more fully hereinafter explained. This rib and the valve member are also centrally provided with pockets or recesses to receive the opposite ends of a coil spring 35 which normally acts to yieldingly hold the barrel in its normal position with the rib 33 thereof out of engagement in the slot 34. In such normal position, the rib 33 extends at a 90 angle with respect to the slot 34 and the port opening 17 in the valve member is positioned at right angles to the fuel passage 14, thereby preventing the flow of fuel through said passage.

In mounting the device in position on the board B, the cylinder lock which is rigidly fixed in position upon the body of the valve by the plate 21 and screws 23, is inserted upwardly through the opening in the floor board, said plate and the upper surface 6 of the valve body engaging closely against the surface of said floor board. The valve body is provided with a plurality of threaded sockets at spaced points to receive the bolts or screws 36 which extend downwardly through openings in the face plate 20 and coinciding openings formed through the floor board. Thus the device is rigidly secured to the floor board. It will also be noted that it is impossible to detach the look from the Valve by the removal of the screws 23, since the heads of these screws contact closely against the underside of the floor board.

Having now described the several structural parts of my invention, the operation thereof will be understood as follows:

In the normal position of the parts as shown in Figure 1, wherein the valve member 16 is in its closed position, the fuel cannot pass through the passage 14 of the valve body from the vacuum tank to the carburetor of the vehicle and it will be obvious that unless the proper key is inserted into the lock barrel 26, said valve member cannot be moved to its open position. Aiso,-even if a key were inserted and the sectional tumblers properly positioned to permit rotation of the barrel member, one unfamiliar with the manner in which said barrel must be operated, would in all probability, not be able to open the valve. In order to move the valve member to open position, after the key is inserted as shown in Figure 1, it is turned to rotate the lock barrel through 90, said rotating movement being limited by the pin 32 engaging one side of the straight longitudinal portion of the slot 31 'in the wall of said barrel. Such rotation of the look barrel positions the rib 33 thereof in parallel relation with the slot or recess 34: in the end of the valve member. The lock barrel is now lite forced inwardly against the action of spring 35 so that the rib 33 is engaged in the slot 3e and the rotation of the lock barrel then reversed, such movement being limited by engagement of the pin in the end of the upper horizontal portion of slot 31 in the wall of the lock barrel. In this latter reverse turning movement of said barrel, the valve. member 16 is, of course, given a. quarter turn so that the port 17 thereof is brought into alignment with the passage 14 through the valve body, thus permitting the uninterrupted flow of the fuel through said valve. In this inward axial'movement of tratedin Figure 3 of the drawings. It is,

' fore, be manufactured and sold at a nomiof course, understood that when the owner of the vehicle'desires to lock the valve in closed position, it is only necessary to reverse the above described operations and then withdraw the key 27.

From the foregoing description considered in connection with .the accompanying drawing, the nature of my present improvements and the several advantages thereof in practical use will be full understood. I have described the device as more especially designed foruse in connection with the fuel supply pipe of a motor vehicle, but it will be manifest that myiinvention might also be advantageously applied to various other analogous uses. It will be seen that the several cooperating elements of my improved valve lock are few in number, simple in: form, positive and reliable in their operation and not liable to getout of order. The device may, therenal price. Since no radical alterations are necessary in the structure of thevehicle in order to properly apply a valve lockin operative ,POSltiOIl, such application of the valve may be readily made by the individual vehicle owner.

Ihave herein referred to the device as being applied .to-the floor board of the vehicle, but it will be under? stood that the same might-also be otherwiselocated and connected in the fuel pipe supply line, as may be deemed most iconvenient.

I have herein described an embodiment of the invention which in actual practice I have found gives excellent results. Nevertheless, it 'Wlll beunderstood that the device issusceptible of embodiment'in various other alternative structural forms and I, therefore, reserve the privilege of. resorting to all such legitimate changes inthe bodied Within the-S form, proportion and relativearran 'ement of the detail parts, as may be fairy emirit and scope of the invention as claim I 3 "1.
