' To all whom t may concern Be itknown that I, WILLTIAM '-llnY- non-,1, a citizenof the United States, residing atBufalo, in the county of Erie and' State specification.

Y This invention relates to` means for fas-V tening a cover, cap orVV closure over the end of a pipe and more particularly to aj fas.- tening deviceY for the covers of4 stop cock boxesorpi-pes. e

It is the objectyof this invention to provide a fastening forthev covers of such pipes or boxes which can be producedY at comparatively low cost, whichpe'rmits' the cover to bef easily and conveniently appliedto or removed from the box, and which` will securely hold thecover on theboxand preventjthe same from becoming displaced by frost Vorv otherwise. f.

In the accompanying drawings: Figure l is avertical section ofa stopcock box or pipe having its cover secured; theretov by my improved fastening. Fig'. 2 is a` detached side elevation of` the' cover equipped with part of the,fas-tener containingvmyinvenj tion. Fig. 3 is a horizontal sectiontaken in line 3-3, Fig. 1, looking upwardly.

ably constructed in the form of a hollowicy-v lindrical tubefor the purpose of making the same' light'and reducing the amount of metal used in the same. vOn thelower part Y of theperiphery of this neck the same', is

provided-with a lclamp-ng screw thread 8f beginning preferably at the lower end ofV theneck andl yextending upwardly around the same' at least one-turn, preferably about one andtwo thirds turns, as' shown in the drawings. The peripheraldiameterof this thread; isless than 4the distance from the- -innerjend o ffthe locking lug 4, and thediametrically opposite .part of the bore kof the i stop cock box or pipe.

`For thepurpose ofL attaching t'hejcover,k

tol the-'boli its threadedshank is. rst passed downwardly i'nto the box or pipe through the spacebetween the inner end of the 'lock- `ing lug and the diametrically oppositepart of the b ox, as shownby dotted lines injFig.

1,' at vwhich time the cover, neck and screw thread are arranged eccentrcally or axially outofline relatively tothe axis of the box.

After-the cover has been lowered sufliciently` tobring a. part ofitsscrew thread below' the lockingy lug of the box and while the flange of the cover ishstillabove the flange ofthe box,the covenis moved laterally so thatthe cover is :in this position the same rotated same iii-axial alinernent with the box and I a part of the screw `en the neck `is, arranged inthe Vdirection forfcausing the screw f tlireadfby wedging engagementi` with the locking lug to draw. .the cover downwardly until the undersideof the cover engages with the lupper 'endofI thelrvbox flangel and the cover flange,V surrounds the .box flange, `4as shown ,by full linesjin'A F ig.` l. By" this means the cover canabe securely tightened and reliably held in place on thebox so that the samecannot be lifted or broken by frost* or otherwise. from the box is effected in a manner reverse to the operation just described fori applying the same to the box.

For the purpose of shiftingthe covenne'ck and thread laterally positively/in a vdirection for engaging apart of thethread underneath' the lockingflugwhen the "neck has beenflowereda sufliicient extent in .thejbox means are. provided .which preferably con? The removal. of Vthe cover sistsf of a shifting lug arranged on the f Yso inner side or bore of the box diametrically opposite to thelocking lug and on a line below the same and provided with an inclined face l0 at its upper end. Upon lowering the neck and screw in the box a part of this thread engages with the inclinedface of the shifting lug causing the neck, n

cover andthread to be shifted laterally for bringing these parts axially in line with the box and carrying a part of the thread underneath the locking lug. This shifting lug therefore insures moving of the clamping thread into engagement with the locking lug at the proper time and facilitates ap-I plying the cover to the box.'

While the cover is screwed down fully on the box the'interlocked flanges of these members 'prevent the coverv from moving laterally relatively to the box, thus confining the screw thread underneath the locking lug and preventing accidentalfdetachment of the cover from the box.

The cover and its flange, neck and thread are preferably cast in one piece for cheapness of manufacture and the same may be turned in either direction for tightening or loosening the same on the box by any suitable means but preferably by means of a Spanner wrench adapted to engage with notches ll, 11 formed on diametrically opposite sides of the cover.

The length of the neck 7 and thediameter of the thread 8 of the pipe closure and their construction and proportion relatively to the pipe l and the locking lug 4 are such that the initial engagement of said thread with the underside of the locking lug may be affected by inserting the shank and thread into the pipe while the same and the disk 5 and flange 6 are tilted relatively to the pipe, after which the parts of the closure may be shifted into an upright concentric position relatively to the pipe'and the closure secondly fastened to the pipeV by turning the same forwardly, so that the screw by working against the lug l will draw the disk 5 and flange 6 against the end o-f the pipe.

I claim as my invention: K

l. A cover for a pipe having anv internal locking lug on one side of its bore while the opposite side of said bore is unprovided with ai locking lug, comprising a disk adapted to extend over the upper end of the pipe, an

i annular depending flange adapted to engage with the outer side of said pipe, a shank depending from the underside of the disk and adapted to extend downwardly along the inner end of said lug, and a screw thread arranged on the exterior of saidshank and extending at least one complete turn cir-- cumferentially around the saine, the peripheral diameter of said thread being less than the distance from the inner edge .of said locking lug to the diametrically opposite part lof the bore of the pipe, said shank and vthread being movable downwardly betweenrsaid lugand the opposite side of the pipe and then laterally for engaging said thread with said lug before said flange engages with the periphery of said pipe.

2. The combination of a pipe provided on one side of its upper end with an internal locking lug and on its opposite side below the plane of the locking lug with a shifting lug having Ianinclined face which slopes inwardly and downwardly, and a cover comprising a disk adapted to extend over the top of the pipe, a shank depending from the disk, and a screw thread arranged on the exterior of said shank and adapted to engage with the inclined face of said shifting lug and to be moved laterally thereby so as to engage another part of said thread with the underside of said locking lug.

3. The combination of a pipe having a flange at its'upper end and a locking lug on one side of its bore, and a cover having a disk extending over the topl of said pipe, an annular flange surrounding the flange of the pipe, a shank depending from said disk, and a screw thread extending at least one turn around the shank and engaging the underside of said locking lug, the peripheral diameter of said thread being less than the distance from the inner end of said lug to the diametrically opposite part of the bore of said box, said shank and thread being movable downwardly between said lug and the opposite side of the pipe and then laterally for engaging said thread with said lug before said flange engages with the periphery of said pipe.

' et. llfhe combination of a pipe having a flange at its upper end, a locking lug on one side of its bore, a shifting lug arranged on the opposite side of the bore of the box below the plane ofthe locking lug and having an inwardly and downwardly inclined face, and a cover having a-disk extending over the top of said pipe, an annular flange surrounding the flange of the pipe, a shank depending from said disk, a screw thread ex tending at least one turn around the shank and engaging the underside of said locking lug, the peripheral diameter of said thread being less than the distance from the inner end of said lug to the diametrically opposite part of the bore of said pipe, and a part of said thread on one side of said shank being adapted to engage said inclined lug for shifting a part of the thread on the opposite side of the shank underneath said locking lug.

5. The combination of a pipe provided on one side of its bore adjacent to the outer end thereof with an inwardly projecting locking lug, and a cover having a disk adapted to extend over the outer end of the pipe, a marginal flange adapted to engage the periphery of the pipe, a shank projecting from llO V1,157,06a y 3 the underside of said disk into thepipe, and into' the-pipe While the same and the disk a screw thread arranged on the outer side of and flange are tilted relatively to the pipe. 10:
