outrun STATES ROBERT E. RUST, OF NEW YORK, N. Y.
PLUMBING SYSTEM.
Application filed April 27, 1923. Serial No. 634,941.
Fig. 1 is an elevation showing a plumbing system embodying my invention; Fig. 2 is an elevation of a modification thereof; Fig. 3 is an elevation of a further modification; F i is an elevation of a still further modification; and Fig. 5 is a section on line 55 of Fig. 4.
My invention relates to a plumbing system for buildings and comprises two stacks so arranged and connected that one stack when used for waste will be vented by the other stack and will thereby prevent back pressures and siphoning of the various fixtures connected with such stacks. My invention in effect may utilize the vent stack as a waste stack and it may provide such connections between waste and vent stack as to eliminate the occurrence of excessive pressures or vacuums; in any event, provision is made for adequate venting so that in such a system I am enabled to connect a much greater number of fixtures than can be employed in the usual vented system. My 111- vention also comprises the various features which I shall hereinafter describe and claim.
Referring to the drawings, 2 indicates a stack having waste, soil pipe and vent con nections 4, 5 and 6, respectively, with the fixtures on alternate floors, and. 3 indicates a similar stack having waste connections with the fixtures on the intermediate floors. The floors are indicated by dotted lines. The stacks 2 and 3 are connected by the cross overs 7, so that when the waste descends through the stack 3 the stack 2 will be vented through the crossovers 7 by the stack 3, and vice versa. The crossovers 7 are of inverted V-shape to prevent stoppage from the waste or flowing from one-stack into another. The arrangement of having .ma-in fixture connections with one stack on alternate floors tends to eliminate the possibility of back pressures or siphoning. I have indicated a connection 8 with a basin fixture leading into the stack 3, as a matter of convenience. The sections 9 of the stacks 2 and 3 are preferably connected by the webs 10, so that in erecting the stacks 2 and 3 there will be no difiiculty in aligning the various sec tions. The crossovers 7 perform alike oifice for the intermediate stack sections.
In Fig. 2 I have shown an arrangement similar to Fig. 1 with the soil pipe connections 5 all arranged in the tack 3 and the basin and bath-tub connections leading into the stack 2'. The crossovers 7, as in Fig. 1,
are of inverted V-shape so as to prevent the waste from the stack 2' clogging the crossovers 7 or flowing into the stack 3. As in Fig. 1, the stack 3 will vent the stack 2, and vice versa.
In Fig. 3 I have shown the stack 2 as being used exclusively for a waste line and the stack 3 as a vent line. In this arrangement the crossovers 7 are arran ed at an angle so as to prevent the waste from flowing into the vent line.
In Figs. 4 and 5 I have shown the two stacks cast in a single pipe, which in cross section is in form like thenumeral 8 In this modification the waste and soil pipe branches 4 and 5 open into the stack 2 Connecting openings or crossovers 7 are provided through the intervening web 11 so as to permit proper venting. This form ofmy invention provides a very compact systern which occupiesa minimum of space within the walls ofthe building. It may also be cast readily.
'My invention provides a plumbing system which is very simple in design, is readily installed, provides ample venting, and at the same time utilizes the stacks to their full ca pacity. I A further advantage in my improved system lies in the fact that it is never necessary to carry a vent line around the waste stack to reach the vent stack. Instead of having to use a jump-over I connect directly with a vent branch 6, 6, 6 or 6 in the side of the nearest stack, as is shown in Figs. 1, 2, 3 and 4: respectively.
As exemplified in the various forms here shown my invention is particularly adapted to provide effective venting by reason of its arrangement of crossovers, which are located at short distances above and below the waste branch openings into the stacks. If the waste running from any fixture creates a plus pressure by forcing air in front of or below it as it runs down .a stack, such air under pressure will pass through the crossover lying immediately below it, and then as the rush of the waste down the stack has caused a minus pressure or a partial vacuum above or behind it in the stack, the air will rush back into the stack from which it has been expelled through the crossover next above, thus almost instantaneously equalizing pressures and preventing the consequent back pressure or siphonage in the fixtures.
