Application August 25, 1949, Serial No. 112,363 g 4 Claims. 1

This invention relates to a double tap T soilpipe fitting.

An object of the invention is to provide a soilpipe fitting of the class described which will be placed entirely within the walls of a house or building, with no part of the fitting showing in the room.

Another object of the invention is the construction of a novel fitting in which the bafiles completely deflect the flow of Water, and which bafiles are completely vented at the crown and are self cleaning.

A still further object of invention is the construction of a soil pipe fitting in which the baffles are horizontally positioned, and which bafiles prevent the waste water from jumping "across the fitting, and which deflects the flow into a spiral downward motion.

A still further object of the invention is to design the body or barrel of the fitting in a slight oval, for a more eificient construction, and in this oval body are perfectly two horizontally positioned baffles that not only prevent the waste water from jumping across the body but which are self cleaning.

With the foregoing and other objects in view, this invention comprises certain novel constructions, combinations, and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a fragmentary vertical sectional view of a wall, showing in vertical section a device constructed in accordance with the present invention.

Fig. 2 is a top plan view of the device.

Fig. 3 is a view at side elevation.

Fig. 4 is a horizontal section view taken on line 4--4, Fig. 3, and looking in the direction of the arrows.

Fig. 5 is a view in side elevation, taken at right angles to Fig. 3.

Referring to the drawings in which the preferred embodiment of this invention is illustrated, l designates the wall structure of an ordinary building in which our invention is capable of being entirely placed. The invention comprises an elongated fitting 2 opened at its upper and lower ends. The fitting 2 is provided with an oval body 3, Figs. 2 and 4, and this oval body 3 is provided with two horizontal side openings extend over theopenings 4, as clearly seen in Fig. 4. These baffles 5 do not project over the central bore of the fittings 2, Fig. 4. Therefore, a cleaning tool can be run down the central bore between the baffies. Each bafiie 5 is beveled at 6, on both of its vertical sides.

The washs'tand units 1 have their waste pipes 8 extending into the horizontal side openings 4 of the oval body 3.

The advantages of our peculiarly constructed horizontal baflles 5 are many, because the prevent the waste flow of Water jumping across the fittings; they deflect the flow into a spiral downward motion; they cause a complete flushing which cleans the fitting and prevents stoppage therein; they permit the correct way of venting, and said baflles have been found to produce a new type of fitting highly efiicient and durable in construction.

By reason of our efliciently constructed fitting it can be placed entirely within the wall of a building with nothing unsightly projecting through the wall, or showing in the room, which is extremely desirable.

It is to be understood that the vent pipe I usually extends through the roof of a building, the vent pipe 1 being of sbstantially the same bore as the major portion of the fitting 2, with the horizontal short bafiles outside of this bore, as clearly seen in Fig. 4, whereby the churning action of the waste water from one of the washstands units 1, or from both of said units 1, will cause a complete cleaning of the fitting at each flushing. Thisv eflicient cleaning of the fitting has not been possible with the old style of fittings known to the trade.

While we have described the preferred embodiment of the invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and we, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What we claim is:

1'. As a new article of manufacture, a device of the class described, comprising a fitting provided with a body, said body provided with horizontal openings, and short horizontal baifies in said body at the openings only and extending partly over said horizontal openings leaving the bore of the fitting clear.

2. As a new article of manufacture, a, device of the class described, comprising a fitting pro- 3 vided with an oval body, said body provided with horizontal openings in the narrowest width of said oval body, and horizontal curved baflies in said oval body at the openings and extending partly over said horizontal openings leaving the bore of said fitting clear.

3. As a new article of manufacture, a device of the class described comprising an elongated fitting provided with a central bore, said fitting also provided with a body, said body provided with horizontal openings, and separate baffles in said body at said openings only and terminating at their outer ends short of the bore of said fit,- tings, whereby a cleaning tool can pass down the central bore between said baflies.

4. A double tap T soil-pipe fitting having an oval body, said oval body provided in its sides with two horizontal openings, said oval body provided at one side of each opening with a short curved horizontal baifle partly extending over the opening and terminatmg short of the central bore of said fitting, and said baili'e at one open ing formed on the opposite side of opening from the position of the baflie at the other opening, whereby liquid discharged through said openings impinges against the other surfaces of said baflies before entering the bore of the fitting.

5. As a new article of manufacture, a soil-pipe fitting comprising a body provided with openings and a central clear bore, said body at the side only of each opening provided with :a short bafiie, and each bafile extending short of the bore of the body and partly over the opening.
