FIGURE 3 is a rear perspective view of the unit,
FIGURE 4 is a vertical section taken on line 44 of FIGURE 1 and showing the unit in the wall opening,
FIGURE 5 is a diagrammatic side elevation on a reduced scale showing the unit in relation to a washing machine in a laundry room of a home.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral designates a one-piece rectangular box-like housing formed of sheet metal and having a forward open side adapted to be arranged vertically in use, a rear vertical wall 11, vertical side walls 12 and top and bottom horizontal walls 13 and 14, as shown. If preferred, the one-piece housing 10 may be formed of plastics material or other like materials of sufficient strength and resist ance to heat.
The housing 19 is provided upon its rear wall at the horizontal center thereof with a horizontal transverse support or channel member 15, open at its opposite ends and having upper and lower longitudinal flanges 16 rigid- 1y secured to the outer face of the rear wall 11 by spot welding or the like. The channel member 15 is provided with a horizontally elongated rectangular guide opening 17 formed therethrough, slidably receiving short lateral extensions 18 of channel-shaped horizontally adjustable hanger brackets 19 which support the housing 10 adjustably in a manner to be described. The extensions 18 carry integral fiat flanges 20 which engage slidably upon the rear face of the channel member 15, as shown. At their outer ends, the hanger brackets 19 carry integral forwardly extending arms 21 at right angles to the brackets 19 and having forward apertured lugs 22 integral therewith and at right angles thereto and extending outwardly of the arms 21, near and inwardly of the forward open side of the housing 10. Rear apertured tongues 23 struck from the material of the arms 21 extend parallel to the lugs 22 in spaced opposed relation thereto and midway between the same. The tongue 23 lie in the plane of the adjustable brackets 19, as shown. The brackets 19 are readily adjustable by sliding longitudinally inwardly and outwardly horizontally relative to the channel member 15. Outward movement of the brackets 19 is positively limited by engagement of the extensions 18 with the ends of the adjustment slot 17. The hanger brackets 19 are adapted to bodily support the housing It) and associated elements during use of the unit within a Wall opening.
As shown in FIGURES 2 and 4, the invention unit is fixedly mounted within a wall opening 24 with the forward open side of the housing 10 substantially flush with the inner finished surface of the wall, shown at 25. To install the housing It? within the wall opening prior to plastering, the hanger brackets 19 are adjusted longitudinally of the channel member 15 to position the arms 21, lugs 22 and tongues 23 into socketing engagement with an adjacent pair of two-by-four studs 26 forming parts of the conventional wall structure. Nails 27 are then driven through the apertures of the lugs 22 and tongues 23 to firmly anchor the brackets 13 to the studs. The housing 10 through the medium of channel member 15 is now floatingly supported upon the hanger brackets 19 and may be shifted horizontally as required for proper centering in the well opening.
Angle bars 28 and 29 are rigidly secured by spot welding or the like to the top and side walls 13 and 12 of the housing 10, near and rearwardly of the forward open side of the housing to provide bearing surfaces around the wall opening for the interior Wall finish 25,- as shown.
The housing top wall 13 isprovided with laterally spaced openings 31 for elbow pipe nipples 31, anchored therein by pipe nuts 32 above and below the top Wall 1-3. Hot and cold water supply lines 33, FIGURE 4, are detachably connected at 34 with the top screwthreaded extensions of nipples 31 above the housing top wall 13. The water lines 33 are arranged within the hollow wall structure in a conventional manner and are fully concealed from view.
Hot and cold water valve bodies 35 are connected with the lower ends of the nipples 31 and lie within the interior of the housing 10 near and below the top wall 13 and about midway between the rear Wall "11 and the forward open side of the housing. The valve bodies 35 are inclined as shown and have their operating handles 36 disposed forwardly thereof and projecting slightly forwardly throughthe open side of the housing as best shown in FIGURE 4 for ready access.
A generally L-shaped divider bracket or partition 37 is removably secured within the upper portion of the housing lti'by sheet metal screws 38 or the like engaging through openings in top and bottom flanges 33 and 40 of the divider partition and also engaging within openings in the housing top wall 13 and rear wall 11. The forward inclined side wall 41 of the divider partition 37 lies close to and parallel with the valve bodies 35 to conceal the latter, and the side wall 41 has openings to receive the valve handle stems. The inclined bottom wall 42 of divider partition 37 underlies the valve bodies 35 at right angles thereto and has spaced openings to receive adapters 43 which serves to couple the lower ends of the valves with the hot and cold water supply hoses 44 leading to the washing machine 45 shown in FIGURE 5. The hoses 44 extend downwardly and through the open side of the housing 10 and then connect with the conventional water intake fittings of the washing machine 45 as shown diagrammatically in FIG- URE 5.
The bottom wall 14 of housing 10 has a central opening 46 formed therethrough for a two part drain hose adapter 47. This adapter has a lower coupling nut portion 48 projecting below the bottom wall 14 for connection with the usual drain pipe 49 concealed within the Wall below the invention unit. The nut portion 48 has an annular shoulder 50 abutting the bottom of the wall 14 and an upstanding externally screw-threaded tubular part 51 integral therewith projecting through the opening 46 and above the bottom wall 14 of the housing. An
. upper locking ring portion 52 of the adapter 47 has screwthreaded engagement over the tubular part 51 and bears upon the top of the same. The locking ring portion 52 also engages the bottom wall 14 and clampingly secures the adapter 47 thereto. A plurality of circumferentially spaced drain slots 53 are formed through the elements 51 and 52 at the level of the housing bottom wall 14 to assure that any water collecting thereon will enter the drain pipe 49. The usual washing machine drain hose 54 is engageable within the bore of the adapter 47, FIGURE 4, to convey the drain water from the washing machine to the drain pipe 49 under influence of the washing machine pump.
A forward rectangular finishing frame 55 is provided having a marginal flange 56 to bear upon the finished wall surface 25 and to conceal the wall opening 24 and the forward edge of the housing 10. The frame 55 has an inner rectangular flange 57 which fits telescopically into the open side of the housing 10 and is preferably dimpled at a plurality of points as shown at The dimpled portions 58 interfit frictionally with coacting recesses 59 in the housing walls to provide a snap fastenor-like connection between the frame 55 and housing, allowing the frame to be snapped into place and secured without the use of screws or other separate fastener elements. The frame is readily removable from the housing when this is desirable. The frame 55 may carry suitable grounding screws 60 for electrical appliances, as
The interior corners of the housing are formed with generous radii to prevent the collection of moisture within the corners and to facilitate wiping or cleaning the interior of the housing with a cloth when desired.
When itis desired to service the valves 35, it is merely'neces'sary to remove the screws 38 and then remove the divider partition 37 from the housing and access to the. valves may then be had without disturbing or removing the'housing l0.
The invention unit is highly compact, neat and attractive injappea rance, and unsightly parts are fully concealie'd-within the wall structure and behind the removable partition si. By employing the invention unit,.water is effectively prevented from dripping down the exterior or interior surfaces of the wall and the device therefore 42 the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or scope of the subjoined claims.
