A sonnen/irren 0E MAiNE 1 `WASTE AND VENT iirr'riNor Application le September 28, 1928. Serial No.i'308,934. i
My invention relates to waste and vent {ittings and comprises a novel combination of fittings the important ones of which in themselves are also new, which provide asimple and compact arrangement constructed to give the maximum etliciency with a small number x of parts. To `this end my improved littings and combinations provide waste and vent connections with a number of natures such as bathtubs, sinks, basins and toilets by which i the waste is discharged into the `waste stack and they are at the saine time vented through a common vent stack. My improved fittings are formed and connected so as to avoid, as completely as possible, sharp angles or abrupt j changes of direction, and thusprevent clog ging of the fittings or siphoning of the ixj tures.
My Vinvention `also comprises features which I shall hereinafter describe rand claim.
i `soil stack A, has the usual vent and toilet connections 3 and fi, and also a laterally .pro-
ject-ing Waste connection 5, which runs into A the enlarged portion 6 of the fitting 2 below the connectioii'opening i for the toilet C, and
- extends outwardly at an angle of about 450,:
preferably termin ating in the hub 7. Canllred `into the hub 7 is the angled lower end 8 of horizontal waste member 9, which has vertically angled branches 10 and 11 and lioriV i Zontally angled branches 12 and 13. VThe branches 10 and 11 are angled at approximately 450 so as to provide a sweep for the flow of any waste down through these branches and eliminate the usual right an-l gled` connection. I have shown the branches 10 and 11, caulked in, respectively, the angled lower ends 11i and 15 of the. vertically disposed melnbers 16 and 17. The member 16 is provided with a connection 18 for a sink or basin D, and in its lower portion acts as a waste member and in itsupper as a vent' membenwhile'the member17 acts as a vent.` Into the upper ends oi the members 16 and 17 are preferably caullred the downwardly projecting branches19 and20 ot' the ,vent pipe 21, which leads through the `upper end ci the toilet vent E22 to` a connection` B, which may be part of `the vent stack. Either of the branches 12i and 13 may be` connected to a bathtub E or other fixtures," and are vented by 4the member 17.
It will bessen that any water running down the vertically disposed member 16 from the basin D `will be diverted `from a "vertical" flow through fits angled end 14C4 into the aligned branch lOLand thence into` the "horizontal waste member.'9.` From thereV it will low,
through its angled end 8, and-through the portionf, which; is alignedwith the end 8, int-o the'enlargement 6 and onintothe soil staclr A. fg, f
YConstructiiig the lower ends 14 and 15 of the member 16 and 17in `alignment with the branches 10 and llwill cause thewaste water` to sweep down tothejmember 9 in such mannerthatit will be forced towardthe end 8 of thatmember,andwaste water will beprel vented from running toward thefixture Eand its trap `@which otherwise is apt to lill iadu-` allyand clog with sediment. "The sweep of the water carries it through the member 9, and from there it is carried in straight run through the end 8 and the aligned. connection 5 to the stack. The changing of the course of the waste water from a vertical run to a horizontal and then back to a vertical run is thus effected without abrupt change of direction and with fa minimum of disturbance. i By so doing there is little opportunity ol oreating water surges or of trapping air, all oit which frequently causes clogging oi the waste members and even of the stack, or the Siphoning of the fixtures, all of which cause'annoy ance, interruption of service and frequent damage.
Vhile I have shown the various fittings embodying my invention with caulked joints,
. it is obvious that various types of joints may be satisfactorily used with my improved fittinge.

rThe terms and expressions which I have employed are used as terms et descriptions and not of limitation, and l have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modifications are possible Within the scope of the invention claimed.
TWhat claim is:
l. ln a Waste and vent system a unitary horizontal fitting having an angled end adapted to Cooperate With an angled eXtension of a v rtical Waste stack, a bell at its opposite end in communication With the discharge from a plumbing fixture and a plu-- rality of intermediate branches extending throughout their lengths at an acute angle to the axis of the fitting and having their end laCes at a complementary angle to said axis, and vertically disposed vent and Waste pipes having angled lower ends adapted to ooop erate with said branches, the arrangement being such that Water discharged into said waste pipe and air drawn through said vent flew freely Without abrupt Changes in direction into said Waste stack.
2. ln a Waste and vent system a trame Colnprising a horizontal tting and a plurality of vertical pipes, said pipes being in communication at their upper endsv with a vent stack, said fitting having branches intermediate its ends extending at an acute angle throughout their length to the axis of said litting, said pipes having` angled lower ends connected directly with said branches, one end ot' said litting being` angled for connection with an angled extension of a Waste stack, and connections for discharging Waste Water from plumbing lizitures into the opposite end ot said litting and into one of said pipes.
In testimony whereof, l have signed my name to this specification this 25th day of September, 1928.
