To all whom t may concern.'

Be it known that I, GUSTAF ALBIN Nn.- soN, a citizen of the United States, and resi dent of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Plumbing Systems, of which the following is a specification, and which are illustrated in the accom* panying drawings, forming a part thereof. The invention vrelates to plumbing, and contemplates certain improvements upon the plumbing system as shown in Patent N o. 993,095, issued to me on May 23, 1911.

The object of the invention is to facilitate the installation of plumbing in buildings, and to this end the invention proposes the use of certain improved iittings which are adapted for adjustable connection with the plumbing fixtures.

A feature of the invention permits of a confinement of the connections which are extended through the floors within a reduced depth whereby the installation of the plumbing in buildings which have fioors of reduced thickness, such as concrete buildings, is accomplished without the extension of any part of the plumbing under the ceiling of a lo wer iioor.

In the accompanying drawings, Figure 1 is a side elevation, partly in section showling an arrangement of the vplumbing for connection with the bath. room fixtures in a building comprising a plurality of floors, Figs. 2 and?) are detail perspective views showing certain of the 'iittings employed in the plumbingj system illustrated in Fig. 1, p is a central transverse sectional view ofanotherfitting, Fig. 5 is a detail plan view of the plumbing system partly in section` Fig. 6 is a sectional view showing the manner in which the wash basin may be connected with the plumbing system, Figs. 7 and S are detail perspective viewsfshowing the ldrain connections for the bath tub, Fig. 9 is a sectional view taken on the line 9-9 of Fig. 5, and Fig. 10 is similar to Fig. 5, but shows a form of construction which may be used when two bath rooms are located upon opposite sides of a common intermediate wall.

thel iioors of the building. Similarly, a. main vent pipe 17 is provided and this main vent pipe extends, as usual, from the lowest floor upon which fixtures are provided eo to a connection, -as 18, with the stack 15, which is above the so-called water level.

In the simple form of construction illustrated in Fig. 1, each 'of the branches 16 of the main waste pipe 17, inclined nipple 19, and an upwardly facing hub or 'nipple 20. 'llhe nipple 19 serves for receiving the end of a drain pipe 21, which drain pipe is in turn connected with both the lavatory, indicated at 22, bath tub, as 23. As shown, the drain pipe 21 extends in nearly a horizontal direction at substantially the floor level and is formedA with two receivinghubs 2d and 24, The

bath tub drain pipe 26 is preferably -con- '35 nected with the hub 2i and continues in the saine direction with the drain pipe 21. The lavatory drain pipe 25, on the other hand, is vertical, and is connected withr the `hub 24a. The closet drain. as 27, with the upwardly facing hub or nipple 20 of the waste pipe branch 1G.

Separate vent connections 28, 29 and 30 are provided for the closet 31, the lavatory 22 and the bath tub 23 respectively. The 85 lavatory connection is illustrated in detail in Figs. 4 and 6. It preferably includes a fitting 32, having alined'nipples 33 and 36 at its top and bottom and an offset downwardly facing discharge arm 34. The dis 90 charge arm 34 of the fitting 32 is connected with the drain pipe 25. The nipple 33 at the top of the itting 32, on the other hand, receives the lower end of the vent connection` 29. An elbow 35 is connected with the. 95

remaining nipple, as 36, of the fitting 32, and the drain, as 37, from the lavatory bowl 22, is connected with the elbow 35. lThe use of the elbow 35, and its connection with the lower end of the fitting 32, permits of a 100A -wide range of angular adjustment in the lavatory drain 37. The length of the lava-A tory drain 37 is further rendered adjust`v ably by mounting a bushing 38 in the endl,

of the elbow 35 for telesc'opically receiving 125 the inner end of the drain 37, in a. well known nia-nner.

The bath tub drain pipe 26 and vent connection 30 are preferably entered in two of the sockets 39, 40, of a 3-arm tting 411. The .11

third socket, as 42, of the tting serves for receiving one end of an elbow 43. The other is formed with an Fig. 5, and the is connected 8o end of the elbow 43 is connected with a clean-,out drum 46, at one side, as through a nipple 44, which is formed on the side of thel drum adjacent its lower end. Inevent the bath tub 23 is located at some distance from the wall (not shown), a length of pipe 45, will lbe extended between the elbow 43 and ably formed upon the side the druin 46 adjacent its'lower end, serves for receiving the nipple 44. A second nipple 47, preferthe drain connection, as 48, from the bath n `tub 23. r

The use of the elbow 43 and its connection wth'the socket 42, permits of the drum 46 being located at any convenient place upon thefbath room floor, as 49. 1 Furthermore, the location of both of the nipples 44 and 47 upon the side of the drum 46 permits of the fittings being confined within a depth which' is not greater than the thickness of the licor, even though the floor may bei of reduced thickness, as when made of concrete. Itwill be understood that the drum 46 has the usual even uponremoval of the cover 50. 'Ehe loremovable cover 50, and that this cover is exposed upon the bath room floor, where it is readily-accessible. It will ybe noted, however," that'the elbow 43 and the receiving bend, as 51 of the drain 48, form a trap,

whereb thechamber of the drum 46 is always lled with water to a level which is above the nipples 44 and 47. There is accordingly no possibility for the escape `of sewergas rom'the drum 46 into the room,

cation `oifthe nipples 44 and 47 upon the sides of `the'drum 46, also provide for the introduction of a cleanin rodA through the' drum intofthe parts which are connected with eitherofsaid nipples.

The closet drain preferably comprises the stem27' 4of. an integral -T-shaped fitting orinedyfvith an upturned receiving bend 52 socket for receiving the lower end "of the 'closet vent connection 28. The provision of the'u wardlyfacingnipple 2Q on the waste 'Lp'fpe ra ch16, and the 'formation of the two I,arms Mibof ,tha-head 53 in axial alinejncnt, pblnit of the closet drain 27 being .turned tohnyangle. It is accordingly unnecessary ,for the length bf the closet drain 27 to correspond with lthe distance at which kthe closet islocated from the wall. It is merely necessary to so locate the stack 15 that the closet drain 27 may be turned `to ben 52 of the drain 27 to register with the closet outlet.


the dproper angle' for causing the receiving ,In both the lower and interniediate oors of a building, the vent connections 28 and 29, lead to the main vent pipe 17 through a branch ventp'ipe'- 56. In the intermediate floors of the building, the vent connection 30, also extends to the branch vent pipe 56. In the lower floor of the building, the main vent pipe 17 may be directly connected with the fittin 41. In the top floor of the building allo the vent connections 28, 29 and AB0 may extend to a horizontal portion of the main vent pipe 17.

While both threaded and calked joints are. shown upon the drawing, it will be undeiwy stood that the several fittings may be con:

structed for the use of either of these forms of' joint, as desired, except that where the rotation 'of the fitting is inconvenient, a pipe., as 29, which has a threaded connection at one end, will preferably be connected to the corresponding fitting at the other end by means of a cal ed joint.

When twoi `'ath rooms are to be located l upon the sanieiidor, the form of construction illustrated in Fig. 10, may be employed.

The construction here illustrated is the same as that already described, except that fittings 57 and 58, ezch vhaving two receiving inlets, as 59, 60 or 1, 62, are employed in place of .j thefittin'gs 32 and 41, respectively. Furthermore the waste pipe branch 16 is formed with two upwardly facing hubs or nipples63 and 64. When the hubs 63 and 64 are used,

the two closets may be alined upon'opposite sides of the wall, as 65, by inclining the two closet drains 27, as shown.
