Ego, Burbank, Calif., assignors to Logan Manufacturing Company, Glendale, Calif., a corporation of California Filed Dec. Sil, 1953, Ser. No. 783,732 8 Claims. (Cl. 4--192) This invention deals generally with plumbing fixtures, and more particularly with a prefabricated, multi-station plumbing fixture.
The present invention provides a prefabricated, multistation plumbing fixture equipped with a horizontally extending housing to be mounted at opposite ends on a pair of stationary building supports in such a way as to render both sides of the housing accessible. Each side of this housing mounts one or more groups of fittings, each 4forming a sta-tion of the multi-station fixture. The present fixture has certain unique features of design and construction which provide the latter with a simple and inexpensive open type construction. One ofthe foremost of these features resides in a novel outlet manifold through which each station of the fixture is supplied with hot and cold water from main hot and cold water headers in the fixture housing.
With the foregoing brief preliminary discussion in mind, a broad object of the present invention may be stated as being the provision of an improved prefabricated, multi-station plumbing fixture of the character described.
A more specific object of the invention is to provide a prefabricated, multi-station plumbing fixture of the character described which possesses certain unique features of construction and design that result in a relatively simple and inexpensive open type fixture.
Another object of the invention is -to provide a prefabricated, multi-station plumbing fixture of the character described in which each station of the fixture is supplied with water through a novel ou-tlet manifold.
A further object of the invention is to provide a novel outlet manifold for a multi-station plumbing fixture of the character described, which manifold is simple in construction, inexpensive to manufacture, and designed in such a way as to permit connection of the outlet fittings of each station of the fixture to the main water headers of the fixture with maximum simplicity and minimum time consumption and cost.
Yet a [further object of the inventionis to provide a.
multi-station plumbing fixture of the character described which is simple in design, inexpensive to manufacture, and otherwise especial-ly well suited to i-ts intended purpose.
Other objects, advantages and features of the invention will become readily apparent as the description proceeds.
Briefly, the objects of t-he invention are attained by providing a plumbing fixture in which 4the housing has opposite side panels between which the hot and cold water header pipes are located one over the other. Within the housing, at each sta-tion of the fixture, and located between the respective side panel of the housing and the header pipes is an outlet manifold of the invention.
Each manifold comprises a body, which may be cast or otherwise made, having at one side concave seats for seating against the pipes and at the other side surfaces for seating against the respective side panel. These manifolds are brazed or otherwise joined to the pipes about the pipe seats of the respective manifolds and are attached to the side panels of the housing. In the illustrative embodiment of the invention, the manifolds are also attached to top and bottom panels of the housing. The pipes are thereby supported in the housing by the supply manifolds.
Extending through each manifold are hot and cold water passages which open at one end through a hot water pipe seat and a cold water pipe seat, respectively, to the hot and cold water pipes, respectively, of the manifold and at their other ends through the opposite side of the body. The control valve means for each station are mounted on the respective side panel and have hot and cold water inlets connected with the latter ends, rcspectively, of the water passages in the adjacent manifold.
One unique feature of the invention resides in the a1'- rangement of the Water passages in the outlet manifolds, whereby holes may be drilled in the pipes, to communicate the Water passages in each manifold with the water passages in the pipes, respectively, after the manifolds have been joined to the pipes. Another unique feature of the invention resides in the manner in which the manifolds seat against the pipes and are held in position on the pipes prior to brazing. Various other unique features of the invention will become evident as .the description proceeds.
The illustrative embodimen-t of the invention comprises a multi-station shower fixture in which the housing also contains a liquid soap supply or header pipe and the housing si-de panels also mount soap dispensers lat the several stations of the fixture. The shower heads of the fixture are mounted on an upper horizon-tal frame meniber which is vertically spaced above the fixture housing proper to provide the fixture with an open type construction which requires a minimum amount of material and may be made at minimum cost.
' A better understanding of the invention may be had from the following detailed description thereof taken in connection with the annexed drawings, wherein:
FIG. 5 is a front elevation of the outlet manifold which i is used inthe fixture; and
FIG. 6 is a view looking in the direction of arrow 6 in FIG. 5.
The illustrated multi-station shower fixture 20 is prefabricated and equipped with a supporting structure 22 including an upper horizontal frame member 24 and a lower hollow rectangular housing 26. Frame member 24 and housing 26 are vertically spaced, as shown, so as to provide the structure 22 with an open construction which requires a minimum amount of material in its fabrication and may be made at minimum cost.
Each side of the housing 26 is provided with several shower stations 28 (only one shown on each side). Each shower station, in turn, comprises a water outlet assembly 30 which is made up of a group of fittings to be presently described and receives water from a vpair of hot and cold water header pipes 32 and 34 Ilocated within and extending lengthwise of the housing 26. Located between each pair of adjacent shower stations 28 is a' liquid soap dispenser 36. The several soap dispensers on the unit 20 are supplied with liquid soap through a soap header pipe 38 which is also located within and extends lengthwise of the housing 26.
The housing 25 comprises a hollow sheet metal struc-` ture` made -from relatively heavy. 'gauge stainless steel,VA
for example. As shown in FlGS. 3 and 4, the housing 26 is generally rectangular in transverse cross-section and comprises a pair of relatively narrow, normally vertical side walls or panels 40 and 42. The upper and lower sides of the housing 26 are formed by a pair of channels 4d and 46, the auges of which are secured to the upper and lower edges of the side panels d@ and d2, by screws 48 to form a unitary structure.
Extending between and rigidly fixed to the left-hand ends of the frame member 24 and housing 26, as the fixture 26 is viewed in FiG. 1, is a hollow, normally vertical frame part Si). The water headers 32 and 34 and the soap header 38 extend beyond the left end of the housing 26 into the vertical frame part 5h and then upwardly through the latter. The upper ends of the headers are open and exposed through an opening in the upper end of the vertical frame part 50 for connection to the water and soap supply piping in the building in which the fixture is installed.
One manner of installing the fixture 2Q in a building is by attaching the vertical frame part 56 to a building wall 52, in any convenient manner, and attaching the right hand ends of the frame member 24 and housing 26 in any suitable manner to a vertical building column 54. The fixture, when installed, thus extends outwardly from and generally perpendicular to the wall 52 so as to permit access to the shower stations 28 on both sides of the fixture.
The outlet assembly 30 of each shower station 28 comprises a shower head 56 which is mounted on the framemember 24. Shower head 56 is connected through a vertical riser 58 to a hot and cold water valve fitting 60, mounted in the manner to be presently described, on a side panel of the housing 26. Each outlet assembly 30 is completed by an outlet manifold 62 located within the housing 26. As will now be described, the manifold 62 is of unique `design and affords a simple and inexpensive means for connectiny each outlet assembly 30 to the hot and cold water headers 32 and 34.
Referring to FIGS. 2-5, manifold 62 will be seen to comprise a relatively flat, generally rectangular body 64 which may be, for example, a single integral casting. This body includes a pair of approximately parallel and generally fiat bars 66 and 68 which are bridged, adjacent their ends, by cross bars 70 and 71. Projecting from opposite sides of the bars 66 and 68, in alignment with cross bar '71, are a pair of extensions 72 havingY cylindrical bosses 74 on their forward sides, as the manifold is viewed in FIG. 5.
These bosses extend normal to the plane of the manifold body 64 and have central threaded holes 76.l
Projecting from the outer edges of the bars 66 and 68 are lugs '73. These lugs have holes St) extending therethrough also normal to the plane of the body 64. The opposite ends of the bars 66 and 68 are ground off flat to provide flat, seating faces S2 and 83 on the upper and lower ends of the manifold body 64.
Projecting from opposite sides of the manifold body,
approximately at the intersections of the center lines of the bars 66 and 68 and the cross bars 76 and 71, are pairs of coaxial cylindrical bosses 84a, 84b through 90a, 90b. Those of the latter bosses which bear the suflix a are located on the forward side of the manifold body as the latter is viewed in FIG. 5, while those bossesidentied by the numerals bearing the suffix b are located on the rear side of the manifold body. The end faces of the forward bosses Sita through 98a are approximately coplanar with or spaced slightly to the rear of the end faces 92 of the lugs '74, as may be best observed in FIG. 2.
The rear set of bosses Sib through tlb have concave cylindrically curved end faces corresponding approximately in curvature to the outer surfaces of the Water headers 32 and 34. As will shortly be seen, the concave end-faeesofthe rearA set of-bossesdbthrough tibpro:
vide concave seats on the manifold body, centered on two parallel axes spaced from one side of the body, for engaging against the outer surfaces of the hot and cold water headers.
To this end, it will be observed in the drawings that the concave end faces on the two upper bosses 8411 and 96h and the concave end faces on the two lower bosses 86h and 88h have common, approximately parallel center lines of curvature which extend transversely of the bars 66 and 68 of the manifold body.
Extending axially through the respective pairs of coaxial bosses 84a, glib through 96a, 90b are water passages or bores 94 through 16d. These bores open at one end through the forward ends of the forward bosses and at their other ends thro-ugh the concave end faces on the rear bosses Sb through gdb. The bores 94 and 96, extending through the two pairs of coaxial bosses 84a, 8d!) and 86a, 86h are in communication via a branch passage 102 within the left hand bar 66.
Referring now to FIGS. 2-4, it will be observed that the manifold body 64 .at each shower station 28 is located Within the housing 26 and disposed in a normally vertical plane between and paralleling the plane of the hot and cold water headers 32 and 34. As previously mentioned, and as may be readily observed in FIGS. 3 and 4, the concave end faces on the upper rear bosses 84b and 90b seat against the outer surface of the hot water header pipe 32. Similarly, the concave end faces on the lower rear bosses Sb and 88h seat against the outer surface of the cold water header pipe 34. The rear bosses are then brazed or otherwise joined to their respective headers as indicated at 104, to provide water-tight seals between the bosses and headers.
The vertical spacing between the planes of the upper and lower seating faces 82 and 83 on the manifold body 6 4 is such that when the latter is in position in the housing 26, these seating faces seat -against the webs of the upper and lower channels 44 and 46 of the housing, as shown in the drawings. The manifoldl body is then secured to the housing by screws 106 which pass through the webs of the channels and are threaded in the upper and lower ends of the manifold body.
It will be observed that the shower stations on one side of the fixture 20 are exactly opposite the shower stations on the opposite side of the xture. Thus, in the completed fixture, the manifolds 62 of the opposing shower stations will be located directly opposite one another. These opposing manifolds are held together, so as to clamp the hot and cold water headers 32 and 34 therebetween, by bolts 10S which pass through the apert'ured lugs 78 on the manifold bodies.
As previously mentioned and as is readily apparent from the drawings, the manifolds 62 serve to support the hot and cold water headers 32 and 34 in the housing 26. The opposing manifolds are clamped together by bolts 108 in the manner just mentioned, primarily to permit proper positioning of the manifolds and to then hold the manifold bodies and water headers in position for brazing of the manifold bodies to the headers during fabrication of the unit.
The manifolds 62 serve also as a `connection between the outlet assemblies 30 of the several shower stations and the hot and cold water headers. To this end, each valveV fitting 60 has a pair of hot and cold water inlet extensions 110 and 112, respectively. These extensions project through openings in the side panels 40 and 42 of the housing 26 and are threaded into the lower bores 96 and 98 in the adjacent manifold bodies 64. The wall of the cold water header 34 has an opening 116 aligned with the inner end of the bore 98i11each of the manifold bodies 64. Similarly, the hot water header 32 has an opening 118 aligned with the inner end of the bore 9'4 in each of the manifold bodies. The outer end of the latter bore on each manifold body 1s closed by a plug 120. From this description, itv will bel-seen that hot water mayow from the hot water header 32 to each shower station 28 through the adjacent opening 118 in the hot water header, and thence through Ibore 94, passage 102, and bore 96 in the adjacent manifold body to the hot water side of the valve fitting 60 of the station. Similarly, cold water may lio-w from the cold water header 34 to each shower station through the adjacent opening 116 in the wall of the cold Water header, and bore 98 in the adjacent manifold body to the cold water side :of the valve fitting 60 of the station. When the valves of a given station are open, hot and cold water flows upwardly through the passage in the riser S8 to the adjacent shower head 56 from whence it issues through the discharge opening 56 of the shower head.
When fabricating the fixture 20, the several pairs of opposing manifold bodies 64 are first brazed to the hot and cold water headers 32 and 34 in the manner already mentioned. The headers are then drilled to provide the openings 116 and 113 by inserting drills through the bores 94 and 98 in each manifold body. The outer end of the bore 94 in each body is then closed by a seal or plug 120. Finally, the housing 26 is assembled by attaching the lower and upper channels 44 and 46 to the several manifold bodies by the screws 106 and -then attaching the side panels 4t) and 42 to the flanges of the channels by the screws 48.
After the housing has thus been assembled about the headers and manifolds, the inlet extensions 110 and 112 of each valve fitting 69 are threaded into the bores 96 and 98 of the respective manifold bodies. The valve fittings are secured to the housing by means of screws 122 which extend through apertured flanges on the respective valve fittings and the side panels 46 or 42 of the housing, and are threaded into the lugs 74 on the adjacent manifold body. The end faces 92 of these lugs provide seating faces which seat against the inner surface of the side panels 40 and 42 of the housing, as shown in FIG. 2.
While the fixture has been illustrated as being supplied with Water and liquid soap through exposed piping, it will be apparent that the fixture may, as well, be supplied through concealed piping. In this case, the frame part 5f) and the vertical headers therein may be omitted and the left hand ends of the frame member 24 and housing 26 attached directly to the Wall.
It will be apparent, therefore, that there has been described and illustrated a multi-station shower fixture and an outlet manifold therefor which are fully capable of attaining the several objects and advantages preliminarily set forth.
While certain preferred embodiments of the invention have been disclosed for illustrative purposes, it will be apparent that numerous modifications in the design and arrangement of parts of the invention are possible within the scope of the following claims.
