VALVE-LOCK.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed 'May 4, 1916. Serial No. 95,513.

description, in connection with the accompanying drawings, is a specication, like letters on the drawings representing like parts.

My present invention is a combined valve lock adapted specially for application to a lock of the Yale or safety type and a standard valve, having a T-head stem or similar arrangement, and a member adapted to connect the turning cylinder of the lock with the valve stem. The object of the invention is to improve and perfect this type of device, and especially to provide an economical and simple arrangement for unit-ing such a lock and valve with provision for free turning movement of the lock barrel the valve is `turned to permit withdrawal of the key in the lock. It is also an object of the invention to enable such a lock to be applied to existing types of valves, particularly those ofthe ordinary T-stem type. A further object of the invention is to provide an efcient cover and assembling arrangement to hold the valve, valve stem, lock barrel and intermediate connecting member in assembled position, protecting the same from disarrangements, dust, or tampering by mischievous persons.

Other details of the invention, novel combinations and advantages will be further pointed out and claimed.

Referring to the drawings,

Figure 1 is a vertical cross sectional view of my device through the lock valve and connecting member;

Fig. 2 is a view partly in cross section at right angles to that shown in Fig. 1; and

Fig. 3 is a perspective view of a novel form of the device or connecting member by which the barrel of the lock and the valve are operatively connected.

Vhile my combined lock and valve device may be advantageously employed in a variety of ways, it is of special importance in application to shut off the gasolene supply in an automobile, thus preventing theft of the ma.- chine, as well as leakage. The valve and lock may be conveniently arranged on the dash of an auto within reach of the driver. Such a dash is indicated at 1, having a recess 2 adapted to receive the lock 3 having the turning barrel a with a slot to receive the key 5, such lock being of the standard -Yale or similar safety type so far as these constructional features are concerned. I make the inner end of the barrel 4L with a projecting portion 6, cut away at one side as indicated at 7 and extending practically across the entire diameter of the barrel at the opposite point, as indicated at 8in Fig. 2, thus affording two smooth faces on the projection 6 as shown at 9 and 10 which are adapted to contact with a lug 11 carried by the member 12, as will be further explained. The projecting portion 6 of *the barrel is furthermore tapped axially to receive the correspondingly threaded shank 13 of a screw 14 intended to secure a washer 15 in position to aid in holding the member 12 and lock barrel together. The member 12 is formed with a bored recess 16 in which the projecting lug 11 is left. A larger and inner recess 17 opening through a slot 18 in the exterior of the member 12 is provided and adapted to receive the washer 15 therein, which is of sufficient diameter to engage the slightly projecting walls between the

recesses

16 and 17, as clearly shown in Fig. 1. The member 12 is also bored at 19 to facilitate the entrance and manipulation of a screwdriver to turn the screw 14. In assembling the member 12 to the lock barrel, the same is fitted thereon, preferably over and upon the slightly reduced portion 20 (seeF ig. 1), the washer 15 is slid through the opening 18 into the inner enlarged recess 17 and the screw 14 fitted through the bored opening 19 and through said washer, and threaded into the tapped recess in the end 6 of the lock barrel. As thus assembled,h rotation of the lock barrel 4: through manipulation of the key 5, will rotate said barrel until one of the faces 9 or 10 of the end projection 6 strikes against the lug 11, whereupon the further rotative movement of the lock barrel 4 will turn the member 12 with said barrel. To adapt the member 12 to turn on or off a valve I cut a slot 21 therein which is adapted to iit over the T-head 22 of a valve stem 23 i in a valve 21 of the usual type, to which are IIJ valve is turned oif by a quarter rotation, the construction above described permits a reverse rotative movement of the lock barrel il: is thus provided for sufficient to rotate the entire barrel into proper position so that the keyl 5 can be withdrawn. This is a feature of special importance in this type of look and necessitates the provision of means to accomplish such withdrawal of the key irrespective of the position in which the T-head 22 and member 12 may be left. The formation of the projection 6 on the lock barrel with the free space 7 therein effects the purpose desired by permitting` said projection to be turned entirely around when one face 10 is bearing against the lug 11 until the other face 9 may bear against said projection 11 and move the member 12 and valve in a reverse direction'from that iirst described.

In order to hold the valve and lock in assembled and protected position, I provide a cover 27, preferably of metal, having a flange 28 formed thereon, which is secured to the inside of a dash 1 by screws 29, or other suitable means. A filling member 30 of wood, porcelain, or any suitable material,

is adaptedto iit solidly within the cover 27 and having a bored recess of appropriate diameter to receive `the member 12 and T- head 22 and permit rotation thereof, is also provided, if necessary.

A further feature of the cover 27, in addr tion to the protection afforded to the device and the holdingof the valve and turning member in assembled relation, is that it acts asfabrace or support for the pipino 25 and 26. As hereinshown in Fig. 1, the valve 24 is fitted closely within the cover 27 and the threaded ends 25`and 26 of the connecting piping are positioned through suitable holes in the cover 27 uniting both cover, valve and pipes rigidly. This aifords a strong, braced construction, and eliminates vibration and further holds the valve in proper position.

The operation of my lock and valve has already been described, and the assembling of the same `with the cover 27, can be easily and quickly effected, such cover constituting both a holder for the valve 24 and a means to retain the lhead 22 into the slot 21 of the turning member 12. The `cover also prevents any meddling with the valve or turning of the same excepting through the manipulation of the lock 3 and key 5. Therefore, when the owner of a car equipped with this apparatus turns off the supply of fuel, and withdraws the key 5, he is reasonably assured that no one willy be able to start the car without the key therefor.

My invention is further described and deined in the form of a claim-as follows:

In a device of the kind described, the combination of a lock, a l'head valve, and an intermediate member` operatively connecting said lock and the T-hea'd of said'valve, said member having a recess in one end to engage the T-head4 of the valve, arecess in the opposite end and a lugtherein adapted to be engaged bythe turning movement ofthe lock barrel, and an inclosing cover coinprising means to'hold said member, valve, and lock in operative position.

In testimony whereof, I have signed my name to'this specification, inA the presence of twosubscribing witnesses.
