UNITED STATES PATENT NIELS C. SUND, OF CHICAGO, ILLINOS.

STOP-COCK BOX.

SPECIFICATION forming part of Letters Patent No. 514,633, dated February 13, 1894.

Application filed September 26, 1893. Serial No. 486,532. (No model T0 all whom t may concern.-

Be it known that I, NIELS C. SUND, a citizeuof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and uscful'lmprovement in Stop-Cock Boxes, of which the following is a specification.

My invention relates to improvements in boxes for the stop-cocks of service-pipes, and more especially to the class of stop-cock boxes formed of extensible members and in which the lower member is provided with an enlarged foot or base-portion, to house the stopcock, and provided at opposite sides with slots i Ithroiugh which the service-pipe may extend.

lTflhile stop -cock boxes of the class described are quite generally regarded as the most desirable for their purpose, it is found 1n their use that as constructed they present objectionable features which it is desirable to overcome. For example, when the box 'is placed in a sandy soil it happens frequently that the sand will work its way up around the stop-cock into the box, making it-a didieult matter to get at the cock with a turningrod or key. Disturbance of the surrounding soil, due to the action of frost orto digging operations in the immediate vicinity, will sometimes cause the box to become tipped, so that the plug cannot be turned with a key, or to become separated from the stop-cock so that the latteris inaccessible; and even if the stopcock can, when separated from the box, be

l reached with a key, there is danger that in endeavoring to turn the plug, the servicepipe, usually of lead, will become fractured.

It is my object to provide a stopcock box of an improved construction, which, while presenting all the advantages of boxes of the class described, will be free from the objectionable features mentioned. i

In the drawings-Figure 1 isa view in elevation, partly broken, of the stop-cock box; Fig. 2, an enlarged section taken on line 2 of Fig. 1; Fig. 3 an enlarged plan Vview of the upper end of the box; Fig. 4, an enlarged plan-view of the underside of the cover; Fig. 5, an en- Iarged broken sectional view oi the base or foot portion of the box, showing a stop-cock in position and partly in section; and Fig.l 6 a section taken on line 6 of Fig. 5, and viewed in the direction of the arrow.

A is the upper member and A the lower member of a stop-cock box, which may be rendered extensible in the common manner shown 'or in any other desirable way. The upper end of the member A is formed with an outer annular recess i aording a seat for the annular flanged rim of a cover s. On the inner side of the said member near the top are tlanges fr r presenting horizontal surfaces, fr', on their under sides, and recesses r2. The cover s is provided on its upper side with a central socket s', at the center of which is an openingthrough which passes a square-headed boltl q. 0n the under surface of the cover is a stop preferably in the form of two downward extending ears s2 s2 at opposite sides of the opening. The shank of the bolt q is threaded and passes through a central threaded opening in a clamping-bar q which extends between the ears s2 and is supported by the bolt. At the lower end portion of the bolt is a pin q2 which prevents separation of the bar from the bolt. To iix the cover upon the box the bolt q is first turned to cause the bar q to recede from the under side of the cover, and in placing the latter in position the ends of the bar q are caused to pass down through the recesses r2 to a plane below the surfaces r. The cover is then turned to the right or left causing the ears s2 to engage and turn the bar q until its ends pass beneath the surfaces fr. A suitable key may then be applied to the bolt to turn the latter and clamp the ends of the bar against the surfaces r whereby the cover is held tightly in place. The cover may be quickly placed in position or removed, and affords an eiective safeguard against the access to the box of dust or moisture.

The member A has atubular body portion and an expanded foot or base portion A2, comprising the enlarged cylindrical part p, with slots p', outer vertical ribs p2, and base iianges p3. This'is a common construction, and is the construction I prefer to employ, because it is easy to cast, affords a base of comparatively large area, and a con venient' means for housing the stop-cock; I do not, however, limit my invention to use with the exact construction illustrated. To carry out my invention I provide on the inner side of the cylindrical' part p, a pair of vertical diametrically opposed IOO Vtongues or ribs p4, in a plane, preferably, at

right angles fo the plane of the slots p.

B is a stop-cock which may be of the usual plug-valve construction. Toward the top of the valve-shell I provide a head n in the form of an annular flange, provided with diametrically opposed grooves Vor recesses 'n'. The shells of service-pipestop-cocks are frequently provided with screw-threads at their upper end-portions, as shown in Fig. 5, and the heads 'n to be employed with such stop-cocksk may be in the form of internally threaded rings to be screwed upon the valve-shells, as shown, orV

Y top of the part p, and closes the lower end portion Vof the box, in a manner to prevent sand from Working its way up into the box,

b-ut not soeffectively aste prevent any Water which may leak from the valve from running out. It frequently happens that the plug of a service-cock becomes worn and loose, and permits water to escape into the box 3 and if the Water thus escaping cannot run out of the box it is apt to freeze in Winter and render the plug inaccessible. The engagement of the head n with the tongues p4 prevents relative displacement between the box and stop-cock, therefore in the event that the box becomes tipped the plug will always be accessible.

Although I prefer to construct the parts as and the effect lwould be to all intents and pur- Y poses the same.

The construction may be further modied in the matter of details Without departing from the spirit of my invention as defined by the claims.

What I claim as new, and desire to secure by Letters Patent, is-

l. In combination, a stopfcock box having a tubular body-portion and an expanded base A2 provided with slots p', anda stop cock litting into the saidslots, to'be housed by the base, and provided with a flange n to enter the said base and close the lower end of the tubular body-portion of the box, substantially as and for the purpose set forth.

2. The combination with a stop-cock and stop-cock box, provided with a base A"z in which the stop-cock is housed, of a head on the stop-cock closing the lowerend-portion of the said bornand a tongue and groove connection between said head and base, substantially as described.

3. The combination with a stop-cock and stop-.cock box, provided with a base A2 in which the stop-cock is housed,ot` a head non the stop-cock, to close the lower end-portion Vof said box, provided with a groove n', and a tongue p4 in the'said base engaging the saidV groove substantially as described.
