VALVE LooK.

Application filed. March 30, 1926. Serial No. 98,529.

This invention relates to valve locking devices and pertains particularly to an improved type of valve lock.

The primary object of this invention is the provision, in a manner as hereinafter set forth, of a valve lock of simple construction and easily and quickly placed in position to lock a valve against unauthorized operation.

The invention contemplates the provision of a pair of relatively flat elongated members designed to be positioned one on each side of a valve of the type having a T-shaped operating head. Provision is 'made for the extension of each of the arms of said T-head through one of the members, and a padlock or other securing means is employed for securing the upper ends of the members together over the head. The lower end of each of the members is provided with means for engaging beneath the nipples by which pipes are secured to the valve, to prevent the members from being moved from position.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding that the invention is not confined to any strict conformity with the showing of the drawing but may be changed and modified so long as such changes and modifications mark no material departure froml the salient features of the invention as expressed in the appended claims.

In the drawing tl Figure 1 shows the locking structure embodying this invention, in side elevation and applied to a valve.

Figure 2 shows the device partly in transverse section and partly in front elevation.

Figure 3 shows a complete front elevation of the locking structure looking towards the side upon which the padlock is positioned.

Referring now to the drawing in detail wherein like numerals of reference indicate corresponding parts throughout, there is indicated generally by the numeral 1 a twoway valve body having the oppositely directed ports or pipe coupling nipples 2 and the valve stem 3 which, as is clearly shown in Figure 2, terminates in the substantially il-shaped operating head 4. This head has the laterally directed portions or arms 5 which are adapted to be engaged by an operating wrench.

A device in accordance with this invention and for the purpose set forth comprises a pair vof curved oppositely disposed locking `elements free of connection with each other. Said elements include relatively long, bro-ad, flat members or bars 6 and 7, respectively, each of which has the end portions thereof obtusely angled as indicated at 8 and 9, respectively. As is clearly shown in Figures 2 and 3, the angled ends 8 are directed from one side of their respective members while the ends 9 are directed from the opposite side. Each of the members 6 and 7 is provided at its central portion with the aperture 10, through which one of the arms 5 of t-he head f1 is adapted to extend as is shown in Figure 2. The members 6 and 7 have their upper ends inclined toward one another as shown, when placed in position, thus bringing the angled portions 8 into relatively close relation and directing the outer angled ends 9 downwardly along each side of the valve body.

Each 0f the end portions 9 of the members tapers toward one` side edge of the member as is clearly shown in Figure 1 and merges into the shank 11 of a hook bill 12. These hook bills are designed to pass beneath and engage the underside of a nipple 2 of the valve, and as is clearly shown the portions 9 taper or are directed in opposite directions that is, referring to Figure 1, the vportion 9 of the member 7 tapers toward the right edge of the member whereas the portion 9 of the member 6 tapers toward the left edge thereof thus causing the hook Shanks 11 to be vdirected downwardly, one on each side of the valvek body, in divergent relation.

v Each of the body end portions 8 is provided with an aperture 13, which apertures come into alignment when the members are placed into position as shown in Figure 2, and through these aligned apertures the shackle 14; of a padlock 15 is passed, thus securing the members in position on either side of the head tot the valve.

It will be readily seen from the foregoing description that when the members 6 and 7 are placed into the position shown in Figure 2, with the hood bills passed beneath the valve nipples 2 in opposite directions as shown, that, when the padlock is in position Cil to secure the ends 8 in the manner as shown, it will be impossible for any unauthorized person to engage the headL of the valve to turn the sarne to open the pipe line in which the valve is placed.

Having thus described niy invention what I clairn is:

A lock for the purposeconlprising a pair of curved oppositely disposed locking elements free of connection with each other, each of said elements having its lower portion in the 'forni of a rod bent to provide a hook formed with a bill to removably einbrace one ot the lateral nipples of a valve body, each of said elements having its upper portion formed of a flat bar extending at right 'angles to the hook, each bar having a pair of alined apertures, the apertures of one bar aligning with the apertures `of the other bar, the lower aligning apertures for the reception of the operating heads of the valve stern, to lock said head, the upper aligning apertures for the lreception of a releasable looking device for said elements, said hooks being curved laterally from each other with a bill peripherally engaged with a nipple at oppositesides of the valve body, and the bars opposing each other and each receiving an arm of the head, said bars being inset with respect to the upper ends or' said rods and extending towards each other.

In testimony whereof, I afiix iny signature hereto.
