3 Claims.

This invention relates to improvements in waste systems and is directed more particularly to a novel waste system for trapped units in a house, office building, or the like.

It is one of the principal objects of the invention to provide a waste system whereby the usual trapped units of a building such as the toilets, water basins, etc., may be more readily and more efliciently drained. The system of the in-- vention includes a novel valve arrangement which, in association with the other parts of the system, is adapted to overcome the objections of the present-day systems not only more eiliciently than has been heretofore known but at less cost.

It is also an object of the invention to provide a distinctive valve device for associating in a Waste system whereby air is readily admitted thereto at desired places and times.

Various other objects of the invention will become more apparent after a reading of the following description and particular reference will be had to the accompanying drawing, wherein:

Fig. 1 is a side elevational view of a waste system embodying the features of the invention; and

Fig. 2 is a side elevational view with parts in section of one of the valve devices of the invention.

Referring now to the drawing more in detail, the invention will be fully described.

In Fig. 1 there is a substantially vertical pipe 2 which I call a waste riser. This extends up through the floors of the building so as to receive drainage from the various trapped units thereon and it has a trap 4 in its lower end. There is also an outlet 6 and preferably a cleanout plug 8 is associated with either the trap 4 or the pipe 2 as desired.

As is well known, buildings of ordinary construction include a number of trapped units, such as at least one toilet and one wash basin on each floor. One of the objections to present day systems is that when a toilet, for example, on a higher floor is flushed the rush of water therefrom into the waste riser creates a substantial suction and draws some at least of the water from out of the trapped units on the lower floors.

Such a situation is, of course, undesirable since no water can get back into the upper trapped units until the same have been manually operated to draw Water thereinto again. Thus, of course,

1937, Serial No. 129,396

the units would not be sealed against the waste riser which, of course, is objectionable.

With reference to Fig. 1 there is shown a water basin W of ordinary form having a trap 20 and a pipe 22 associated therewith leading into the waste riser 2: A toilet bowl is indicated at B in Fig. 1 and this also has a trap 30 and a pipe 32 leading into the riser 2.

It is desired to point out that the trapped units, as well as the traps, may take many and various forms but, as is well known, they are all adapted to hold water therein when desired and drain into the riser when desired.

There is shown at B a lower toilet and this has a trap and an outlet pipe 38. It will be noted that the pipe 32 leads into the riser 2 at a point below pipe 22 and that pipe 38 leads into the riser at a point still farther below.

It will then be appreciated that the flushing of toilet B will cause the drainage thereof and the water rushing therefrom into the waste pipe 2 will setup a suction or syphoning effect therein. This will draw water from out the trapped units W and B and into the waste system, which, as pointed out above, is objectionable. Furthermore, such syphoning action has the tendency to break the trap seal and allow obnoxious sewer gases to escape back into the rooms containing the fixtures.

According to this invention, however, means is provided whereby this objectionable effect is overcome. That is, I provide for air to be admitted into all of the trapped units whenever the suction effect is set up in the system and thus prevent the trap seals from being broken or the trapped units from being undesirably drained.

This means takes the form of a valve device II] which I associate with openings in the outlets leading from the traps to the waste line. While this device may take various forms, it preferably includes a casing 40 which is adapted to be associated with the outlets in some suitable way and this has an opening surrounded by a seat 42.

A reciprocating piston 44 is provided and this has on its inner end a valve disc 46 adapted to seat against seat 42 in the casing. Spring means such as 43 may be provided to urge the valve disc into the closing position shown in Fig. 2, while there may be a stop to limit the downward movement of the rod 44. There may or may not be a covering such as 50 secured to the outer end of the rod.

With this arrangement as air is drawn downwardly in the riser 2 by the drainage from one of the trapped units, it will be seen that atmospheric pressure causes the valve disc 46 to be moved away from its seat so that the opening in the valve casing is uncovered and in communication with opening 36 in the outlet. Thus air is immediately admitted to the other outlet pipes and the suction that would otherwise be set up is counteracted.

With reference to Fig. 1, it will be noted that the valve device l overlies an opening 36 in outlet 32 and there may be a lip or gland such as 34 associated therewith to prevent drainage from escaping therethrough. It will be noted that gland 34 is of such form and so located that the water is directed downwardly and its flow through the outlet pipe is facilitated.

The gland 34 thus also serves to prevent drainage from clogging the opening 36 or from becoming lodged near the valve. The lip 34 may, of course, vary in size and shape.

While I have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto 1. The combination with a waste pipe of a trapped closet bowl having a discharge, a connection between the discharge and waste pipe, a vent valve in said discharge, and a gland in said discharge overlying the vent valve.

2. The combination with a closet bowl having a trap and a vertically-directed discharge and an opening leadinginto said discharge, a valve in said opening adapted to be opened by suction in said discharge, and a gland extending downwardly in the discharge spaced from and disposed over said opening.

3. A closet bowl formed to have a trap and a discharge for connecting to a Waste line leading downwardly therefrom, the wall of the bowl around the discharge having an opening therethrough, a valve device over said opening having an opening normally closed by a spring-pressed member adapted to be moved to open position by suction in the discharge, and a gland in the said discharge extending from above the opening in the wall of the bowl outwardly and downwardly at a distance from the opening with its lower end spaced from said wall to provide pro-. tection for the opening and admit the passage of air through the valve into the discharge.
