SANITARY PIPE FITTING.

Application filed December 29, 1923. Serial No. 683,346.

; To all whom it may concern:

Be it known that I, ALEXANDER E. MAG- DONALD, a citizen of the United States, re-

siding at Worcester, in the county of'Wor ccster and State of Massachusetts, have in-' vented a new and useful Sanitary Pipe Fitting, of which the following is a specification.

This invention relates to a pipe fitting for use at each fioor of a building for connecting closets and other fittings with the soil pipe and properly venting the-same.

The principal object of the invention is to provide a comparatively simple cast fitting for this purpose, which when connected up, will eleminate a large number of fittings,

some of them special, and several feet of piping at each floor, thus economizing in thev materials used and especially in the labor.

The invention involves a fitting constituting a combination T and Y and having special means to vent the side passage wh ch forms part of the Y, the Y being horizontal at the top.

Reference is to be hadto the accompanying drawings, in which Fig. 1 is a viewof the soil pipe and connections for three'floors of a building with a preferred embodiment ofmy invention ap-' pliedthereto on the first and second'floors;

Fig. 2 is a side view of the fitting on en'- larged scale;

Fig. 3 is a plan of the same; and i r Fig. 4 is an end view.

, I have shown the invention as applied to i a soil pip e'10,1a1though it can be applied to a stand pipe, drainage stack or the like. This soil pipe is shown as extending down through three floors of a building at each of which it isadapted to 'be' connectedwith a closet, bath tub, sink and the like. I have shown the building ,as supplied with two and having hubs and openings at opposite ends for. receiving, sections of the soil pipe 10 me well known manner. In the same vertical plane as the center oftheupright partl-l is the'cente'r of a hub 12 which is designed to, be connected with the outlet 13 from a closet. It will be seen that this part of the fitting constitutes a T, an interior passage from the hub 12 opening down into the upright passage in the part 11 right section 11. 'This' part of the device is vented by a vent passage 14 in a hub 15 ter'- minating'i'n the plane of the end hub 16 which constitutes the top of theu pright pop tion 11 and which receives-the lower end of the soil pipe 10 above. These parts are all substantially symmetrical with respect to the vertical plane whichpasses through the centers of the upright ll and the hub 12.

Now to describe the Y part of the device, the throat 17, which leads from the upright part 11 to the hub 12' and which is curved The hub 12 is located between the ends of the up} in order to allow the water to flow down into the soil pipe, is provided with a side extension 20 having a passage therethrough'.

This passage communicates with the interior of the fitting and extends: on a slight curve into themain channel thereof. It terminates in a hub 21 which has its terminalplane in the same vertical plane as the end of the hub 12. This hub 21 is provided for the purpose of connecting with a drain pipe 22 from the bath tub, sink, washing machine, or other fixture or fixtures which may be located in the same room or adjacent thereto. The difliculty comes in venting this part of the device so that when two closets are flushed on different floors a siphon will not be formed to empty one of the traps. This venting has been done heretofore by a se arate pipe which had to be connected'wlth the other vent pipe and involved a great deal of unnecessary expense as I' have found;

For the purpose of venting this angular part 20 of the Y, I cast it when'it ismade with a, hollow projection 23 extendin'g'practically from the outer side thereof clear over tothe vent passage 14 and into which it extends. This hollow projection '23 thus permits. air to enter it from all parts of the side passage 20 of the Y and delivers the air into the vent passage 14. I

The vent pipe 25 extends-up vertically from the vent passage 14 and is secured in the usual Way in the hub 15. This passes up to a-fitting.26 on the second floor above the second fitting A.. The vent pipe27 on this floor, [which corresponds with the vent pipe 25. below, enters this fitting 26 makes the venting a very simple matter."

- I n the caseof the top floor the fitting B does not necessarily have this additional venting feature because it cannot interfere with any discharge from any floor above. The ventpipe extends clear up above the top floor and enters into the soil pipe through a fitting 28 as is usual.

As heretofore constructed there is the main vent pipe which has a fitting below the bottom floor connected to the soil pipe. The main fitting is provided with a vent pipe which extends upwardly a short distance and is then connected by a fitting to the main vent. p ps having only a single vent pipe on the first floor and also avoid the extra fitting by, which the old vent pipe was connected with. the soil ,pipe including. a T or Y below the fitting A. On thesecond floor all these fit tings above mentioned are'also avoided as well as a cross for connecting what corresponds with the vent pipe 27 with the vent pipe 25, and with the other vent pipe from the fitting immediately below the fitting A on; that fioor. In addition to this there are several elbowsand other fittings that are liminated- In fact altogether I count that I provide eight or nine fewer fittings on the second floor than] have been necessary heretofore and do. away with several feet of vent pipe. The same saving is made on.

all floors between the first and top floors. I

s also simplify the soil piping by not having vent pipe enter it at all directly.

TIn, this way theflnecessary venting is secured all the along the line and there is nonecessity for putting any fittings, except the ones herein illustrated, into the soil pipe anywherefrom the bottom to the top ofithe building; This is all done by one casting at eachfioor and the vent. pipe itselfand its fittings are reduced in cost by a very large percentage without any danger of clogging the pipe. Yet the breaking of all the vacuums is prevented.

' The arts above described can constitute the entire fitting if desired but in some cases I prefer tones the pipe 22 and side extension 20 for one purpose only, as for example the bath tub. In that case the pipe 30 from thesink and 31 from thewash tray drain into the branches of a double Y 32. This discharges directly down into a hub 33 integral with the cast fitting A. Below the hub 33 is a vertical branch 34 communicating with the main upright part 11 to discharge therethroughf In this case these parts are vented directly by a vertical vent pipe 35 connected with the vent pipe 27 above. I I g Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be madatherein by any person skilled in the artw1thout departlng from the scope of the invention as expressed in the claims. There-- This fitting I avoid, 1

having an air passage adapted to be connected with a vent pipe, and the side pas sagehaving' an upwardly extending hollow projection to vent the side passage and communicating with the vent passage withinthe body of the fitting, whereby the entire fitting can be vented by a single vent pipe.

2. As an article of manufacture a T-Y fitting for a soil pipe or the like comprising a main vertical hollow body having. a branchextending therefrom at right angles for communication with the outlet of a water closet and provided with a side inlet passage communicating with the interior of the fitting at the same level for connection with a bath tub, wash basin or the like, the fitting having communicating'with. the main portion thereof an air passage adapted to be connected, with a vent pipe extending directly up from it, and the side passage having an' upwardly extending hollow projection extending across it in order to vent the side passage all the Way across and communicating with the Vent passage within the body of the fitting.

3. As an article of manufacture, a 'T Y fitting for a soil pipe or the like comprising a main vertical hollow body having a branch extending therefrom and provided with a side passage communicating with the interior of the fitting and an air passage adapted to be connected with a ventpipe extending up from it, and the side passage having an upwardly extending hollow projection to vent the side passage and communicating with the vent passage Within the bod'y'of the fitting and located part way betweenthe vertical portion of the fitting and the points at which the same is adapted tobe connected with the waste pipe from the closet bowl and the like.

4 As an article of manufacture a T-Y fitting for a soil pipe or the like comprising a main vertical hollow body having a branch extending therefrom at right angles for communication with the outlet of a water closet and provided with aside inlet passage communicating with the interior of the fitting for connection with a bath tub, wash basin'or the like, the fitting having, communicating ,with the main portion thereof, an air passage adapted to be conup from it, and the side passage having an upwardly extending hollow projection extending across it in order to vent the side passage all the way across and communicating with the vent passage within the body of the fitting, the side passage being inclined downwardly toward the interior of the fitting, and the hollow projection being located horizontally above it and communicating with it substantially all the way across it.

5. In a soil pipe system, the combination with a vertical soil pipe, of a T-Y fitting at each floor, said fittings below the top floor each being provided with a hub for connection with a water closet, and a hub for connection with a sink, bath-tub or the like substantially at the same level, each fitting having a vertical air vent passage between the first named hub and the main water passage down through it, for the purpose of venting that portion of the'i fitting, and a recess within the fitting communicating with said passage and arranged to conduct the air into said passage from all points across the portion of the fitting which communicates between the second hub and the main vertical passage in the fitting, a

single vent pipe extending upwardly from the vent passage for venting both parts of the fitting, and a main vent pipe extending upwardly along the soil pipe and connected at one point only with the first named hub.

6. As an article of manufacture, a fitting for a soil pipe or the like comprising a main hollow body having a branch extending fitting having a vertical side passage communicating with the main hollow body to receive the outlets from a sink and wash tray and vented by a vertical vent pipe extending directly up from it.

In testimony whereof I have hereunto aflixed my signature.
