46 .9E/ij l se 42 lll l INVENTOR GORDON C. RUSSELL `Agent United States Patent O 3,141,472 TRAP AND DRAIN MANFULD Gordon C. Russell, Studio City, Calif., assigner to Loekheed Aircraft Corporation, Burbank, Caiif. Filed Apr. 2, 1962, Ser. No. 184,346 3 Claims. (Ci. 137-2161) This invention pertains to new and improved plumbing fixtures; more specifically this inventon pertains to trap and drain structures and to flush tank valves.
In the co-pending application Serial No. 189,417 filed April 23, 1962 entitled Buildings, buildings and similar structures are disclosed which are constructed utilizing rigid panels and consisting of a core of cellular polyurethene or similar material located between rigid walls. In this co-pending application the utilization of so-called core plumbing and heating units within such buildings is disclosed. Because of size and other limitations conventional plumbing fixtures are considered satisfactory for such core units as disclosed in this application. A broad object of the present invention is to provide new and improved plumbing fixtures which are of such dimension that they can easily and conveniently be employed in such core units, but which are also capable of being employed elsewhere.
Another object of the present invention is to provide new and improved trap and drain manifold structures capable of being used in such core units, but which are also capable of being employed wherever it is desired to connect a plumbing fixture such as a water closet of a sewer pipe in the same general area in which it is desired to connect at least one drain to such a sewer pipe. Another object of this invention is to provide new and improved trap and drain manifolds as indicated which may also be easily and conveniently manufactured at a comparatively nominal cost, which may be created out of various plastic, corrosive resistant materials and which are capable of giving satisfactory service over prolonged periods. p
These and various other objects of this invention as well as many specific advantages of it will be more fully apparent from a careful consideration of the remainder of this specification, the appended claims and the accompanying drawings in which:
FIGURE 1 is a cross-sectional view of part of a building employing plumbing fixtures as herein described showing how these plumbing fixtures are oriented with respect to one another and to other plumbing fixtures used in conjunction with them;
FIGURE 2 is a partial cross-sectional view taken at line 2 2 of FIGURE 1 of the drawing showing a trap and drain manifold of this invention;
FIGURE 3 is a partial cross-sectional view taken at line 3-3 of FIGURE 2 showing the trap and drain manifold illustrated in the preceding figure.
The accompanying drawings are primarily intended so as to clearly illustrate certain presently preferred embodiments or forms of plumbing fixtures falling within the scope of the present invention. From a careful consideration of these drawings and of the remainder of this specification those skilled in the art pertaining to drain traps, sewer connections, fiush valves and the like will realize that other differently appearing plumbing xtures may be designed and created on the basis of the disclosures embodied within these drawings and this specification through the use or exercise of routine engineering skill or ability without departing from the inventive features herein shown and described.
As an aid to understanding this invention it can be stated that it concerns trap and drain manifolds, each of which includes: an elbow having upper and lower ends,
lice
the upper end of which is adapted to be attached to a toilet bowl, at least one drain opening located within the curved portion or part of the elbow, a flange located with respect to the drain opening so as to deflect awayV from it any material discharged into the upper end of the elbow and a vent connection located above the flange.
The actual nature of this invention is more fully explained by referring directly to the accompanying drawings. In FIGURE l there is shown a portion of a building 10 containing a kitchen 12 and a bathroom 14 which are joined by means of a common wall 16. Within an opening 1S in this wall 16 there is positioned a plumbing and heating core 2l) as described in the aforenoted application entitled Buildings. As indicated in this co-pending application this core unit is preferably preassembled at an appropriate manufacturing facility prior to its being installed Within a specific building, such as the building 10.
In the building 10 the core 20 contains a trap and drain manifold 22 formed from any inexpensive or relatively inexpensive corrosive-resistant material such as polystyrene, urea-formaldehyde polymers, or the like as indicated in FIGURES 2 and 3 of the drawing which serves so as to connect a toilet bowl 24, a shower drain 26, a wash basin drainZS and a kitchen sink 30 to a sewer pipe 32. This trap and manifold construction 22 is formed so as to include what may be termed a elbow 34 having an upper end section 36 and a lower end section 33 joined by means of a curved, centrally located intermediate section di). The lower end 38 is preferably of a cylindrical configuration and is dimensioned as indicated in FIGURES 2 and 3 of the drawing so as to fit within a bell-shaped end ft2 in the sewer pipe 32. The upper end 36 of the trap and drain manifold 22 is preferably formed with a terminal fiange 44 which is designed so as to receive a cylindrical extension 46 extending from the toilet bowl 24.
Within the trap and drain manifold 22 three separate drain pipes 4d are provided so as to lead into the interior of the curved part 40 adjacent to the lower end 38 of it through drain openings 5t). These openengs 50 are all located in the same plane and are spaced from the portion of the curved part 40 having the smallest radius of curvature. Each of the drain pipes t8 is provided with a generally U-shaped trap portion 52 which is located beneath the level of its drain opening 50 and adjacent to the elbow 34. As indicated in FIGURES 2 and 3 of the drawing the different drain pipes 48 are connected to the shower, basin and sink drains 26;, 28 and 30 respectively, through the use of conventional pipe couplings 54 along the sides S6 of the core 2d.
Within the trap and drain manifold 22 material passing from the toilet bowl 24 into the elbow 34 is prevented going into the drain opening Sil and into the trap portions 52 by means of an internal curved flange 53 attached to the center of the curved part 4@ so as to extend downwardly generally toward the center of the curvature of the curved part 4i). It may be noted that this flange 58 extends into the interior of the curved part 4) only a comparatively short distance so as not to interfere with the passage of material from the upper end 36 of the elbow 34 along the portion of the curved part 40 having the smallest radius of curvature and that it (the flange 58) extends only around the uppermost portion of the curved part 40.
Above this flange 5S there is formed in the curved part 40 a small chamber 60, the uppermost extremity 62 of which is located above the upper end 36 of the elbow 34. This extremity 62 is adapted to be connected to a vent pipe by a conventional coupling 66. Below the flange 5d beneath the drain openings 50 there is located a sloping wall 6'7 which extends parallel to the flange 58 3 along the length of this flange end which leads to the interior of the lower end 38.
From a consideration of the trap and drain manifold 22 the utilization of this construction will be essentially obvious. When it is connected as shown material from the toilet bowl 24 can pass through it without hindrance to the sewer pipe 32 and the flange 58 will tend to direct such material so as to prevent it from passing through the drain openings Sil into any of the trap portions 52. When material passes through the shower drain 26, the basin drain 28 or the sink drain 30 such iluid will catch within a trap portion S2 and will, of course, pass through this trap portion 52 in an established manner. These trap portions 52 will effectively form gas seals preventing the escape of sewer gas through the drains 26, 28 and 30. Any such gas will escape through the vent pipe 64. With this construction there is effectively no chance of the vent pipe 6d of ever becoming clogged.
Although the trap and drain manifold 22 has been described in the preceding in connection with the use of three different drain pipes i8 from a careful consideration of the foregoing it will be realized that the principles of this invention can be applied when only one drain pipe 48 is utilized with this trap and drain manifold 22, and that if desired any number of different trap and drain pipes corresponding to the pipes 48 may be used with this trap and drain manifold in the same manner as the pipes 48 herein described.
The core 20 in the building l0 contains a flush valve 70 which is employed so as to control the iiow of water from a supply pipe 72 into the toilet bowl 24 through an outlet pipe '74. During the use of the flush valve '70 water is stored within a closed tank or reservoir 76 until such time as the valve '70 is actuated so as to supply water to the outlet pipe 74- so that this pipe can convey such water to the toilet bowl 24.
From a careful consideration of the foregoing it will be realized that plumbing fixtures as herein described may be manufactured out of any such polymers with a minimum of diiliculty at a comparatively nominal cost using established manufacturing techniques. It will also be realized that when any of the plumbing xtures herein described are formed out of suitable polymeric plastic materials that these iixtures will give satisfactory service over prolonged periods and that they will be substantially a corrosion-proof character.
Because of the nature of this invention it is to be considered as being limited solely by the appended claims forming a part of this disclosure.
I claim:
