To all whomit may-concern,

Be it known that I, WILLI M J. Rumour,

a citizen of the United-States, residing at Freeport, in the county of Stephenson and :State of Illinois, have invented new; and

useful Improvements in Valve-Locks, of which the 'followingvis aspecification. 1

This invention relates to; valvelocks. The object of the invention is to provide means, whereby valves may be locked against operation, the primary object being to cut of]? the fuel'supply.of'motorivehicles and to lock the saidzcutoff for the purpose of preventing the operation of the vehicle by unauthorized persons. Y

. ri urther object is to provide means combined .with the cut 0a locking means, for preventing the removal of the .valves, said means; forming a casing for partly surrounding the unionsby which the valve'is coupled to the supply pipe, thereby preventing access to said unions until the removal of the valve-locking means.

A further object is to provide an element engageable with the valve operating handle and the valve and pipe unions, with; means for automatically locking the same in position and when so 'locked, will remain in position until the removal of the sameby the use'of a-key ofspecial design. r i

With the ab-ove and other objects in view,

the invention consists of the following novel combination and arrangement of parts, hereinafter more fully described and illustrated in the accompanying drawings, in which;

Figure 1 is a side elevation of the valve provided with the improved locking means constituting the invention;

Fig. 2 is an end elevation of the same, the

connecting pipe of the valve being shown in section;

Fig. 3 is a transverse sectional view through the valve locking element, illustrating the valve in position therein in elevation;

Fig. 4 is a longitudinal sectional view through the casing of the valve locking element, illustrating the automatically operated locking bolt therein; and

Fig. 5 is a detail perspective view of the locking bolt.

Referring to the drawings in detail, A indicates a valve of the type usually employed in the fuel feeding means of a motor vehicle, B a P on f the-s pply Pipe th e-for and is coupledlwith the pipe.

:The locking element which constitutesthe invention, comprises a casing 10 formed of any suitable material, the saidlcasing being of elongated, formation and] provided inter- ,mediate its ends, with a transverse slot 11,

adapted to receive the operating handle 12 PatentedNovLfi,191?.

C the coupling bymea nsofwhichthe valve of the valve. The casing 10 is provided with agfia-t bottom 13 andapreferablyoval top The bottom extends beyond the sides ,of thecasing in.amanner to overlie the valve and isbentat an angle for the purpose of receiving the top'flange of the e said valve. The lockingelement; further provided with a pair OlfcOilpllIlg engaging members 15, these members being formed by a continuation of the locking element andg as shown in Figs. 1 and 2 areadapted to engage and partiallysurround the pipe co u plings.

B this constructionjthere is provided "a :locking element which is readily. engageable with the valve operating handle 12and with the couplings by means of which. the 5 $upply pipe is connected with the valve,

For the purpose of securing this element .upon the valve 'andpreventing its unauthorized removal, the casing 10 is provided itha spring actuated locking bolt '16. This ,bolt is formed with a slotted end 17, its opposite end being adapted to overlie and engage the handle 12 of thevalve for the purpose of preventing its removal through the slot 11, as will be seen by reference to Fig. 4 of the drawings. The locking bolt 16 is provided with a lug 18, against which is adapted to engage a spring 19, which normally urges the bolt in position over the handle 12. The casing 10 may be provided with lugs 20 upon each side thereof for the purpose of guiding the bolt 16 in its movements. Located near the engaging end of the bolt 16 is a notch 21 which is adapted to be engaged by a pivoted dog 22, the said dog being provided with a'cam 23 lying within the path of the handle 12, as it enters the opening 11; This dog 22 is eccentrica-lly pivoted as at 2 1, so that when the handle 12 enters the casing through the slot '11, the dog will be rocked upon its pivot and through its engagement with the notch 21, will release the bolt 16, which through the action of the spring 1.9 will be shot across the opening 11, thereby preventing the removal of the said handle. Pivoted tothe casing 10 at 25, is a gravity dog 26 lying within the slot 17 of the bolt 16 and being adapted to engage the end of the said slot for the purpose of preventing a reverse movement of the bolt. It is of course obvious that a spring actuated dog maybe substituted for-the gravity dog if desired. The dog 26 is of sufficient width to normally lie below the bottom plane of the bolt 16, so that when it is desired to remove the locking element, the key which is inserted through the key opening 27 in the casing 10 will engage and lift the said bolt for the purpose of releasing the same. A further turning of the key will cause the withdrawal of the bolt through the engagement of the said key with the lug 18, the dog 22 then engaging the notch 21 and holding the bolt 16 in its retracted position.

While the invention shown and described is applied to a fuel supply for 'motor vehicles, it is of course understood that it is susceptible of use for various purposes and .may be employed wherever it is desired to 2a look a valve,.

Having described the invention, what is claimed is,-

1. A valve lock comprising a casing provided with a slot extending entirely across the same for the purpose of receiving a valve operating handle, abifurcated extension carried by said casing, said extension forming laterally and downwardly extending hook members adapted to contact with and partly surround the valve coupling and means carried by said casing for locking the same to the valve operating handle.

' 2. The combination with a valve and pipe couplings therefor, of a casing provided with a slot to receive the valve operating handle, pipe coupling engaging members carried by said casing and a locking element within said casing, said element being operated by the insertion of the valve handle within the slot to automatically lock the valve against operation.

3. A valve lock comprising a casing provided with a slot extending entirely across the same for the purpose of receiving a valve operating handle, extensions carried by said casing and adapted to contact with and partly surround the valve couplings, a spring actuated bolt mounted in said casing, means for holding said bolt in an inoperative position and means whereby, when the valve operating handle is inserted in the slot it will release said bolt holding means and automatically lock the casing to the valve operating handle.

4 The combination with a valve and pipe couplings therefor, of a casing provided with a slot to receive the valve operating handle, pipe coupling engaging members carried by said casing, a locking bolt mounted within said casing for movement across said slot, means for locking said bolt in a retractedl position, means whereby the entrance of the valve handle within the slot will automatically release said bolt, a locking dog pivoted within said casing for engagement with said bolt to lock the same across said slot and means formed on said dog for engagement with a key to release Copies of this patent may be obtained for five cents each, by addressing the "Commissioner of Patents.
