VALVE OR BALL-COCK.

SPECIFICATION forming part of Letters Patent N c. 674,276, dated May 14, 1901.

Application filed May 26, 1900. Serial No. 18,096. (No model.)

To all whom it may concern,.-

Be it known that I, GEORGE B. MOORE,a citizen of the United States ot' America, and a resident of Springeld,in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Valves or Ball-Cocks,'of which the following is a full, clear, and exact description.

This invention relates to improvements in valves, and more particularly to ball-cocks employed in water-closet tanks; and the invention is most especially applicable as an improvement on the construction of ball-cock illustrated in Letters Patent of the United States issued to me September 8, 1891, No. 459,044, in which description of valve the valve proper'is carriedby a stem which plays through one section of the valve-body and which valve has its location within he chamber of the other section of the valve-` ody, the valve opening against and closing with or being closed by the water-pressure, requiring no springs. As well known, ball-cocks of this class when employed in connection with a tank and the supply-pipe therefor have usually a member thereof screwed to the tank, and Where the valve-casing is constructed in the two halves or sections, as vshown in the aforementioned patent, and it is desired to repair the valve by the replacement of a packing-disk therein or otherwise, as commonly becomes necessary after protracted use of the valve, the entire valve must necessarily be either unscrewed or unfastened from the tank and uncoupled from the supply-pipe or the ball-cock and its carrying arm or lever must be detached from the valve and its stem, so that the casing-section with which the ballcock arm is connected may be unscrewed and disconnected from the other. In either of these ways of gaining access to the interior of the valve-casing for the purposeof replacing the valve proper or the packing thereof or other packing or otherwise fixing or replacing a part of the valve it is very difficult to get at the parts and at best requiring more or less straining, hammering, or unscrewing,the inconvenience being as great again in the reassemblage of the parts.

The principal object of this invention'is to provide in a ball-cock or valve of the character indicated, and which comprises two detachably-connected casing-sections and has combined therewith a lever-arm and ballfloat, a construction and'means for connection of the two parts of the valve body or casing, so that the part carrying the valve proper and the valve-stem, with which 'the iioat and its lever-arm are connected, may be most readily, quickly, and easily detached from the other part or section, which is screwed or otherwise connected to the tank, or in any case at least is connected or coupled with the 'supply-pipe,and without the necessity of turningv part of the valve-body to be removed to 'unscrew it from its connectionwith the other section of such body.

` To these ends the invention consists in the valve or ball-cock constructed as hereinafter fully described, and set forth in the claims.

Reference is to be had to the accompanying drawings, in which the present improvements are comprised in a ball-cock fora water-closet tank of substantially the character illustrated in my aforementioned Letters Patent, and in which- Figure 1 is a central longitudinal vertical section through the ball-cock shown as mounted upon the edge of a tank. Fig. 2 is a cross section through the two portions of the valvecase adjacent their joint as taken on the line 2 2 and showing parts beyond such line in elevation. Fig. 3 is a -perspective view showing the yoke-clamp which is employed in conjunction with the valve-case sections as removed.

kSimilar charactersof reference indicate corresponding parts in all of ythe views.

In the drawings, A represents .the body of the valve, of a general cylindrical form, the same being necessarily for the assemblage of the parts made in the two casing-sections a and b, united by the novel means hereinafter described. The section b has its outer end screw-threaded or is otherwise adapted to be coupled with a supply-pipe, while the forward' end of the section a is closed by the screwcap or cup-shaped nut c. The rear end of the casing-section a has the contracted and somewhat-elongated opening e, leading forwardly into the valve-chamber f, from which lthe outlet-passage g leads.

The portion of the valve-casing a which surrounds the entrance-opening e thereinto IOO is externally constructed as follows: The extremity is formed with the annular lip or end flange 10, which constitutes the seat for the valve C, while forwardly therebeyond the surrounding wall is for a portion of its length, as indicated at 12, made in the form of the frustum of a cone, at the expandedend of which is the annular flange 14, the'forward face 13 of which is beveled or widened as it ap-V proaches its junction with the exterior of the casing proper. The separable inlet-section l) of the valve has its forward end constructed with the outwardly-flaring mouth, as indicated at 17, which, together with the frustoconical portion of the valve-case section a, is ground for a close fit by such part 12 within the flaring mouth 17. The said section b of the valve-case has exteriorly at the end surrounding the flaring opening 17 the flange h, the rear side of which is beveled or inclined to correspond to the flange 14 of the other section a, and the sizes and tapers of the portion 12 of valve-casing a and the flaring mouth 17 of valve-casing b are relatively such that when these two tapered or inclined portions are assembled the said conical portion 12 will bottom in the mouth of the valve-casing section b before the flanges 14 and h can come into contact with each other, so that there is always afforded an opportunity for draft through the medium of these flanges of the one casing-section endwise toward the other, and the two sections of the valve constructed with the taperingr fitting portions and the external flanges beveled as described are when the valve is applied in use held together by a yokeclarnp of peculiar construction, (shown in the drawings,) which will be now described in detail. This clamp B consists in the two clamp halves or sections t' j, each half or section comprising the intermediate approximately semicircular part 2O and the end ears 22 22 and 23 23. The earpieces 22 of both clamp-sections are halved togetheror otherwise matched, as common in hinged joints, and connected by the hinge-pivot 21, while the opposite ears 23 23 have perforations 211 25, the latter being tapped for the reception of the thread of the screw 7c, which engages therein, the head of the screw bearing against the top of the ear of the other section having the plain or unthreaded perforation. The intermediate semicircular portion 20 of each half-sectiont' and j of the yoke-clamp B has within its inner edge a depression or trough m, the opposite walls of which are convergent, as indicated in Figs. 1 and 3, and corresponding more or less closely to the tapering of the flanges 111 and h of the casing-sections a b. The clampyoke being placed about the adjoining flanged ends of the two sections o, b of the valve-casing, and contracted by the screw, serves by the cam-like actiono'f the inclined surfaces of the trough-grooves of the yoke-sections on the beveled flanges of the said casing-sections to crowd the conical portion of the one, a,tightly into the flaring mouth of the other,b.

The lower clamp-section is shown as supported by and as a part of an upright n, which rises above the base or foot plate o, adapted to be secured by screws p to the upper edge of the tank D, in connection with which the ball-cock is used. The said foot-plate is constructed with the upstanding guard flange or rib 25 between the outer edge of said plate andthe upright n, and the surface of said plate inwardly beyond the said guard-flange 25 inclines downwardly and inwardly, as indicated by the dotted line 26 in Fig. 1, whereby in the event of any slight leakage of water through the valve-case at the joint of the two sections a and b in case the water should follow outwardly along thecasing-section l) past the yoke-clamp, dripping from such section, such drippings will by the said guard 25 be prevented from running to the exterior of the tank, but will be guided down into the tank.

It will be apparent that if the parts a b of the valve-case were screw-united it would be necessary in order to replace or pack the valve C or otherwise repair the parts carried by or within the casing-section a, to either remove the connections that carry the ball-float, which owing to the almost inaccessible location of the parts is very dillcult, or to unco'uple the valve at from the supply-pipe, and especially in cases where a lead supplypipe is used and the valve-case is screwed to the top of the tank it is also necessary to remove the screws which fasten the ball-cock to the tank; butin the present contrivance it will be understood that by turning with the thumb and finger the screw 7c to unfasten the separable sections of the yoke-clamp and overturning or throwing open the upper clamp-section it is only necessary to raise the valve-body a small fraction of an inch `to bring the external [langes 14 h clear from the trough or groove m in the lower yoke-clamp section, whereupon the valve-casing section a, with the valve C, valve-stem C2, ball-float G, its carrying-arm G2, lever t, and link u, may be all bodily removed from the casingsection b, which remains intactpin its connection with the supply-pipe. The replacement of the partsor their restoration is effected also just as conveniently.

I claim- 1. Ina tank valve or ball-cock, in combination, the casing-section b having a chamber therein for the disposition of the valve, constructed for connection with the v\' rate1'-supply, and having at its forward end the ilaring circular mouth, the end of which is surrounded by the flange h the end face of which is perpendicular to the axis of the section while its back is beveled as shown, the casingsection a having its rear portion 12 tubular and of frusto-conical form adapted to fit into the Haring mouth of section l) and having its rear end comprised in an annular lip 10 of less diameter than the said portion 12 and extended into the chamber of the section b be- IOO IIO
