Description:

This invention relates to plumbing fixtures, and more particularly to plumbing fixtures having a plurality of valves for controlling the flow of water to other plumbing fixtures.

One of the objects of the present invention is to provide a superior plural-valve plumbing fixture in which the supply of water to a desired one or more of the plurality of control-valves may be shut off to permit the convenient inspection and repair of such control-valves without requiring the use of additional piping.

A further object of the present invention is to provide a superior plural-valve plumbing fixture having a distributing-head and so constructed and arranged that the water supply may be conveniently cut off from the said distributing-head and the latter readily removed and replaced as required.

A further object of the present invention is to provide a superior plural-valve plumbing fixture in which the water supply to a given one of the control-valves may be readily shut off at a point adjacent the latter without requiring the removal of the usual escutcheon-plate.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art and which are not claimed by me in a separate application.

The particular plural-valve plumbing fixture herein chosen for illustration includes a hollow distributing-head or ring 20 which may be conveniently formed by casting and which in the instance shown is provided with four corresponding forwardly-projecting externally- and internally-threaded tubular extensions constituting valve-bodies or housings 21, 22, 23, 24, and each located at one of the four corners of the distributing-head, which latter is of substantially-rectangular form.

Vertically intermediate the integral valve-bodies 21 and 22, the distributing-head is formed with a hollow enlargement 25 complementing a similar hollow enlargement 26 formed on the opposite side of the distributing-head vertically intermediate the valve-bodies 23 and 24 before referred to. Horizontally intermediate the valvebodies 21 and 23, the distributing-head is formed with a hollow enlargement 27 corresponding to the enlargements 25 and 26, before referred to, and complementing a similar hollow enlargement 28 located horizontally intermediate the valvebodies 22 and 24.

Leading downwardly from the hollow enlargement 26 of the distributing-head is a cold-water connecting-passage 29, the lower end of which extends beneath an integral partition 30 (Fig. 3) in which is threaded a removable and replaceable tubular valve-seat bushing 31 having a polygonal water-passage 32 leading forwardly to the adjacent end of a cold-water passage 33 leading to the interior of the enlargement 28 before referred to (Figs. 3 and 6).

Engageable with the forward face of the valveseat bushing 31 to check or regulate the flow of cold water from the enlargement 26 to the enlargement 28 of the distributing-head, is a valvehead 34 provided with an externally-threaded enlarged portion 35 engageable with threads 36 formed in the inner periphery of the valve-body 24 and serving when rotated by means of a 56 valve-stem 37 to advance and retire the valvehead 34 as a whole toward and away from the valve-seat bushing 31.

The valve-stem 37, above referred to, extends , outwardly through a sealing-washer 38, a clamping-washer 39, and a packing-nut 40, and is provided at its outer end in any approved manner with a valve-handle 41. The packing-washer 38 is preferably formed of indurated fiber and is seated against the outer edge of the valvebody 24 by the clamping-washer 39, which in turn is seated against an inwardly-facing clamping-shoulder 42 formed in the packing-nut 40 intermediate a packing-pocket 43 therein and the internally-threaded skirt 44 thereof. The packing-pocket 43 of the packing-nut 40 is filled with fibrous packing material 45, and the skirt 44 of the said packing-nut is engaged with threads 46 formed upon the outer periphery of the valvebody 24, as clearly shown in Fig. 3.

The valve mechanism above described and located in the valve-body 24 constitutes, in the structure shown, a cold-water control-valve and, for convenience of description, will be generally designated by the reference character 47. The remaining valve-bodies 21, 22 and 23 are in the. order named provided with a hot-water controlvalve generally designated by the reference character 48, a hot-water control-valve generally designated by the reference character 49, and a cold-water control-valve generally designated by the reference character 50. The mechanism of each of the valves 40, 49 and 50 corresponds to the mechanism of the cold-water control-valve 47, and where parts thereof appear in the drawings, such parts bear similar reference characters.

Leading downwardly from the enlargement 25 of the distributing-head 20 to the hot-water control-valve 49 in the valve-body 22 is a hotwater connecting-passage 51, and leading from the said valve to the enlargement 28 is a complemental hot-water passage 52. Leading upwardly from the enlargement 25 to the hot-water control-valve 48 in the valve-body 21 is a hotwater connecting-passage 53, and leading laterally from the said valve to the enlargement 27 is a hot-water passage 54. In a similar manner, a cold-water connecting-passage 55 leads from the enlargement 26 upwardly to the cold-water con,u trol-valve 50 in the valve-body 23, and in turn, a cold-water passage 56 leads laterally from the said control-valve 50 to the enlargement 27.

Centrally intersecting the enlargement 25 of the distributing-head 20 and extending from Sfront to rear therethrough is a passage 57. Similarly, the enlargements 26, 27 and 28 are respectively provided with central passages 58, 59 and 60. The passages 59 and 60 respectively formed in the enlargements 27 and 28, each receive one I;I of two corresponding water-outlet connectingmembers, generally designated by the reference character 6 1, one of which is especially well shown in Fig. 7. Each of the said water-outlet connecting members 61 includes a forwardly-projecting i5 externally-threaded stud-like portion 62 and a rearwardly-extending socket 63 having internal threads and receiving the externally-threaded forward end of a water-outlet nipple 64.

Each water-outlet connecting-member 61 is also formed with an axial water-passage 65 communicating at its rear end with the socket 63 and communicating at its forward end with a transverse water-passage 66 extending diametrically through the stud-like portion 62. The passage 66, together with the passage 65, forms a Tshaped water-passage and communicates at the respective opposite ends of the transverse portion 66 thereof with the water-passages leading to the particular one of the enlargements 21 and 28 in which the given connecting-member 61 is . mounted.

Each water-outlet connecting-member 61 is formed with an integral sealing-flange 61 of rounded form in cross-section and adapted to make a substantially-line contact with the sloping surface of a rearwardly-facing sealing-seal 68 formed in the rear face of each of the enlargements 27 and 28 concentrically with the passages 59 and 60 respectively therein. Formed in the forward face of each of the enlargements referred to, concentrically with the passages 59 and 60 respectively therein, is a forwardly-facing conical sealing-seat 69 which is engaged by the transversely-curved inner face 10 of a wateroutlet sealing nut, generally designated by the reference character 71. The said sealing-nut is provided with an internally-threaded socket 72 closed at one end by an end-wall 73 and receiving the externally-threaded stud-like portion 62 of the complemental water outlet connectingmember 61.

By tightening the sealing-nut 71, the sealingflange 67 of its complemental connecting-member 61 is seated against the conical sealing-seat 68 in the rear face of the distributing-head 20, and at the same time the transversely-curved inner face 70 of the said nut is firmly seated against the forwardly-facing conical sealing-seat 69 in the forward face of the said distributing-head. In this manner the leakage of water from within the distributing-head and past the contacting surfaces 67-68 and 69-70 is effectively prevented.

Furthermore, any water which may leak between the threads of the portion 62 of the connectingmember and the threads in the socket 12 of the sealing-nut 71 is prevented from leaking outwardly by the end-wall 73 of the said nut.

As before pointed out, each of the connectingmembers 61 (one being connected to each of the enlargements 27 and 28) has coupled to it a nipple 64, the rear end of each of which is threaded into an elbow 75. Each of the elbows 75, just referred to, is preferably formed with a polygonal portion 76 seating in a similarly-shaped socket 77 formed in a sheet-metal template 78, all as is more fully shown and described in my co-pending application, Serial No. 130,093, filed March 10, 1937.

The elbow 75 connected to the enlargement 27 has connected to its upwardly-extending arm an outlet-pipe 79 leading upwardly to a shower-head or the like (not shown). Similarly, the downwardly-extending terminal of the elbow 75 connected to the enlargement 28 has connected to it an outlet-pipe 80 leading to a bathtub or the like (not shown).

Placed over the distributing-head 20 and concealing the same, as well as concealing the inner portions of the four valve-bodies 21 to 24 inclusive, is a sheet-metal escutcheon or finishingplate 81 having in the instance shown a rearwardly-extending polygonal flange 82 contacting with the outer surface of a wall 83 and including a substantially-flat front-portion 84 which is provided with four equidistant perforations 85 through which respectively extend one of the valve-bodies 21, 22, 23 and 24. The front-portion 84 of the escutcheon or finishing-plate 81 is also formed with two corresponding perforations 86-86 respectively located vertically intermediate the valve-bodies 21-22 and 23-24. For the purpose of conveniently retaining the escutcheon 81 in place, a cup-shaped retaining-nut 87 is threaded upon the external threads on each of the integral valve-bodies 21 to 24 inclusive.

Installed in each of the passages 57 and 58 respectively formed in the enlargements 25 and 26 is one of two corresponding water-inlet connecting-members, each of which is generally designated by the reference characters 88, and each of which is formed with a forwardly-extending studlike portion 88 and a rearwardly-extending skirt 90 providing a rearwardly-opening threaded socket 81. The socket 91 of each of the waterinlet connecting-members serves as an entryend thereto, which opens to a source of water supply and in the arrangement shown receives the externally-threaded forward end of a nipple 92. Each connecting-member is also formed with an axial water-passage 93 leading forwardly from the socket 91 and intersecting at its forward end a transverse water-passage 94 extending diametrically through the stud-like portion 88.

The passage 94 together with the passage 93 forms a T-shaped water-passage and communicates at the respective opposite ends of the transverse portion 94 thereof with the water-passages leading away from the particular one of the enlargements 25 and 26 in which the given connecting-member 88 is mounted.

Intermediate the socket 91 in each of the connecting-members 88 and the axial passage 93 therein, there is provided at the said entry-end of each water-inlet connecting-member 88 a valve-seat 95 of conical form, but which may be generally characterized as rearwardly facing.

The water-inlet connecting-members 88 correspond to the water-outlet connecting-members 61, before described, save that each of the connecting-members 88 is provided with a valve-seat 95 and also has its stud-like portion 89 formed with a threaded axial passage 96. In the passage 96 of each connecting-member 88 is threaded the externally-threaded central portion 97 of a shutoff-valve gate-unit, generally designated by the reference character 98. Projecting rearwardly from the threaded portion 97, just referred to, is a relatively-slender stem 99 carrying at its rear end a valve-head 100 having a conically-contoured forward face 101 adapted on occasion to engage with the valve-seat 95 in the connectingmember 88. Extending forwardly from the threaded portion 97 of the gate-member 98 is a relatively-large cylindrical operating-stem 102 formed in its forward end with a kerf 103 by means of which the gate-unit 98 may be turned, for the purpose as will hereinafter appear.

Each of the connecting-members 88 above described is formed with an integral sealing-flange 104 of rounded form in cross-section and adapted to make a substantially-line contact with the conical sloping surface of a rearwardly-facing sealing-seat 105 formed in the rear face of each of the enlargements 25 and 26. Formed in the forward wall of each of the enlargements 25 and 26 concentrically with the passages 51 and 58 respectively thereof is a forwardly-facing conical sealing-seat 106. Each sealing-seat 106 is engaged by the transversely-curved inner face 107 of a water-inlet sealing-nut generally designated by the reference character 108 and having an internally-threaded socket 109 receiving the externally-threaded stud-like portion 89 of the complemental water-inlet connecting-member 88. The sealing-nut 108 of each of the connectingmembers 88 is formed with a forwardly-extending sleeve I 10 which is both internally and externally threaded as shown in Figs. 3 and 9. The operating-stem 102 of the gate-unit 98 extends forwardly through the sleeve 1 0 and is surrounded by packing material I I located in the said sleeve 110 and compressed therein by a gland-nut I12 which is threaded within the said sleeve I 10. Removably threaded upon the exterior of the sleeve I 1 is a cup-shaped cap 113 having an end wall 114 provided with a knurled periphery and also having a rearwardly-extending tubular flange 115 which is both internally and externally threaded at its inner portion. The internal threads of the flange 115 engage with the external I. threads of the sleeve i10 of the sealing-nut 108 while the external threads of the said flange are engaged by the internal threads of a cupshaped retaining-nut I J which ordinarily bears against the front face of the escutcheon 3I and 20 serves to provide a finishing-member which conceals the external threads upon the cap 113.

As before pointed out, each of the water-inlet connecting-members 88 (one of which is connected to each of the enlargements 25 and 26) has 25 coupled to it a nipple 92. The rear end of each of the said nipples is threaded into an elbow I1i each of which is formed with a polygonal portion 118 seating in a similarly-shaped locating-socket 119 in the sheet-metal template 78 before described.

The elbow 17 connected to the enlargement 25 has connected to its downwardly-extending arm a hot-water supply-pipe 120 and similarly the downwardly-extending arm of the elbow I 17 leading to the enlargement 26 has connected to it a cold-water supply-pipe 121.

The particular plural-valve plumbing fixture herein chosen for illustration provides for either selectively or simultaneously supplying a mixture of both hot and cold water either to a showerhead or to a bathtub or the like, as will be obvious from the foregoing description and the accompanying drawings. Thus, for instance, should the valves 48 and 50 be simultaneously opened, both hot and cold water will flow upwardly through the pipe 79. In a similar manner, should the hot-water valve 49 and the cold-water valve 47 be simultaneously opened, a supply of water would be delivered to the depending outletpipe 80. If either or both valves of both sets of valves are simultaneously opened, water will simultaneously be supplied to both the pipes 79 and 80.

For the purpose of illustrating certain of the advantages of the present invention, let it be presumed that the fixture is installed in the manner illustrated in Figs. 1, 2 and 3 and that it should develop that the distributing-head or ring 20 is defective and leaks. Under such circumstances, both of the caps 113 would be unthreaded from their complemental sleeves I 10 (forming a feature of the sealing-nuts 108) to thus make accessible for engagement by a screw-driver or other suitable tool the kerf 103 in the forward end of the operating-stem 102 of each of the gate-units 98. Each of the gate-units 98 is now turned by means of a tool inserted in the kerf 103 until the valve-head 100 is shifted from the position in which it is shown in Fig. 3 to the position in which it is shown in Fig. 4 to thereby bring the said head into sealing engagement with the shut-off valve-seat 95 at the entry-end of the complemental connecting-member 88.

In the above manner the water-pressure is cut off from all four of the control-valves 47 to 50 inclusive and-the same may be dismantled to permit the removal of the escutcheon or flnishing-plate 81. All of the retaining-nuts 87 and 116 are now removed and the said escutcheon 81 is in turn removed from over the distributingring or head 20.

The gland-nut 112, after the stop-pins 102a have been removed is loosened. Each of the two sealing-nuts 71 and each of the two sealing-nuts 108 are now unscrewed from their respective connecting-members 61 and 88.

The distributing-head or ring 20 may now be removed for repairs or immediately replaced by another distributing-head which is known to be in good condition. During the operations before described it will be noted that the water-supply through the water-inlet connecting-members 88 to the interior of the distributing-head or ring is definitely shut off and then the said ring may be removed from the connecting-members without occasioning the leakage of water from the supply-pipes 120 and 121.

In the event that it becomes necessary to repair the control-valves 47, 48, 49 and 50, it is only necessary to remove the appropriate cap 113 and turn the exposed operating-stem 102 by means of a screw-driver to seat the valve-head 100, against the seat 95 in the ccr-necting-member 88. It will be noted from the foregoing that inasmuch as the shut-off-valve gate-units are carried by the inner connecting-members, the effectiveness of such gate-units is not impaired by the removal of the sealing-nuts or even by the removal of the distributing-head or ring itself.

Fig. 13 shows another form of shut-off valvemechanism suitable for use with plural-valve plumbing fixtures of the present invention. In the structure of Fig. 13 a distributing-head or ring 122 is employed which generally corresponds to the distributing-head or ring 20, before described, and like the same is provided with a transverse water-passage 123 communicating with the hollow interior of the distributing-head 122 and terminating at its respective opposite ends in conical sealing-seats 124 and 125. Projecting through the transverse passage 123 is the stud-like portion 126 of a connecting-member which is generally designated by the reference character 127 and which includes a rearwardlyprojecting internally-threaded sleeve 128 receiving a water-supply nipple 129.

Formed in the connecting-member 127 and leading forwardly from the interior of the sleeve 128 is an internally-threaded passage 130 intersecting at its forward end a water-passage 131 which extends diametrically across the stud-like portion 126 and communicates at its respective opposite ends with the hollow interior of the 60. distributing-head 122. Installed in the waterpassage 130, just referred to, is a valve-seat bushing 132, the forward conical face of which is adapted to be engaged by the rear face of a valvehead 133 forming the rear terminal of a shutC5 off-valve gate-unit, generally designated by the reference character 135. The valve-head 133 extends rearwardly from an externally-threaded portion 136 of the said gate-unit, which portion is threaded into an internally-threaded bore 137 formed in the stud-like portion 126 at a point forwardly of the transverse water-passage 131 therein. The gate-unit also includes a forwardly-extending operating-stem 138 which passes through an externally- and internallythreaded sleeve 139 forwardly offsetting from a sealing-nut 140, generally corresponding to the sealing-nut 108 of the structure illustrated in the figures preceding Fig. 13. Located in the sleeve 139 of the sealing-nut 140 is a body of packing material 141 which is held in place by a gland-nut 142 threaded into the interior of the said sleeve 139.

Threaded over the exterior of the sleeve 139 of the sealing-nut 140 is the tubular flange 143 of a cup-shaped cap 144 which includes also a convex front-end wall 145. By removing the cap 144, the kerf 146 in the forward end of the operating-stem 138 is made available for manipulation. The sealing-nut 140 is provided with an annular transversely-rounded sealing-flange 147 which seats against the conical sealing-seat 124 in the forward-face of the distributing-head 122.

In a similar manner, the connecting-member 127 is formed about midway of its length with an annular transversely-rounded sealing-flange 148 which seats against the rearwardly-facing sealing-seat 125 formed in the rear wall of the distributing-ring 122.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended-claims are intended to be embraced therein.
