PIPE FITTING AND BOWL ASSEMBLY Victor A. Hofimann, Harvey, Ill. Application October 1'7, 1938, Serial No. 235,317

8 Claims. (Cl. 4-252) This invention relates to an improved. pipe Positioned at the outermost end of the horifitting and bowl assembly. The fitting is espezontal pipe 58 and extending upwardly therecially adapted to support and provide an outlet from is a pipe 20. The upper portion of the pipe for a stack hung bowl. is turned upon itself to form an inverted U or a One of the principal objects of advantage and siphon 2! and thence forwardly as is clearly importance of the device of this invention reshown in the drawing.

The flush pipe 46 passes through the opening 36 in the securing plate 32 and is held in water tight engagement with the opening 44 by drawing the gland 50 against the annular shoulder 48 by means of the bolts 52 which engage the threaded apertures 54 in the gland 50.

It will be apparent that the flush pipe connection as well as the discharge connection between the bowl and siphon are made from the front of the device. The necessity of providing a working space in the rear of the fitting for assemblin the parts is entirely eliminated.

Inthe operation of the improved pipe fitting and bowl assembly of this invention, a stream of water is directed through the jet 26 and upwardly into the siphon 2! slightly in advance. of admitting water into the bowl 42. A siphon action is thus created and the water level in the bowl raises but slightly, if at all, as the water enters the bowl.

It will be apparent from the foregoing that herein is provided a stack hung bowl and pipe fitting assembly which is sturdy, rugged and may be economically produced. It is to be noted that the improved device of this invention leaves the fioor space directly beneath the bowl entirely unobstructed. The clearance between the bottom of bowl and floor is exceptionally great.

It will also be apparent from the foregoing that herein is provided a device of the kind referred to, the siphon and soil pipe of which may be completely concealed within a conventional wall. Additionally, the improved device does not require working space in the rear of the structure for assembly.

Moreover, because the discharge connection is below the water line, leakage of gas through this joint into the partition or wall of a building in which the device is used is positively prevented. Additionally, the improved bowl of this invention requires from 4 to 6 inches less space from the wall than a conventional bowl. Also the bowl may be flushed with either an automatic valve or a tank.

It will be apparent to those skilled in the art to which the device appertains that numerous changes and alterations in construction and design may be made all without departing from the spirit or scope of this invention. Accordingly, it is understood that the patent granted hereon is not to be limited to the preferred embodiment here disclosed nor in any other manner except as necessitated by the terminology of the appended claims when given the range of equivalents to which they may be entitled.

I claim as my invention:

1. A pipe fitting including a siphon and vent pipe adapted to be positioned within a vertical wall, a vertical stack pipe, the discharge end of siphon being permanently secured to said stack pipe, and means for attaching a bowl to said fitting, said means including a securing plate having a plurality of anchor bolt receiving recesses therein.

2. A pipe fitting including a siphon and vent pipe adapted to be positioned within a vertical wall, a section of stack pipe, said siphon and said vent being permanently fixed to said stack pipe, a jet positioned near the intake end of said siphon, and means for attaching a bowl to said fitting, said means including a securing plate having a plurality of anchor bolt receiving recesses therein.

3. A pipe fitting including an inverted U-shaped portion forming a siphon and vent pipe adapted to be used with a stack hung bowl, a stack, said inverted U-shaped portion being permanently secured in operable association to said stack, the length of the discharge leg of said siphon being constant, siphon actuating means in operable association with said U-shaped portion, and means for attaching a bowl to said fitting, said means including a securing plate having a plurality of anchor bolt receiving recesses therein.

4. In combination with a stack hung bowl having a substantially horizontal discharge passageway, a pipe fitting having a portion adapted to be attached to said bowl, said portion being provided with a plurality of bolt receiving recesses, said recesses being adapted to prevent rotation oi? bolts positioned therein, said pipe fitting including a vertical stack and a discharge pipe, a siphon intermediate the ends of said discharge pipe, one end of said discharge pipe being permanently secured to said stack, and a siphon jet directed upwardly into the interior of said siphon.

5. The combination with a stack hung bowl having a substantially horizontal discharge passageway of a soil pipe fitting, said fitting including a section of stack pipe, means operable from the front of said fitting for removably securing said bowl and said fitting together, said means including a plurality of bolt receiving recesses in the fitting, said means being adapted to secure bolts against removal or rotation, the joint in the discharge passageway between said bowl and said fitting being below the water level of said bowl, a siphon in the fitting intermediate the ends thereof, means preventing the alteration of the length of the discharge leg of said siphon, and means for admitting a flushing liquid into said bowl.

6. In combination with a stack hung bowl having a substantially horizontal discharge passageway, a pipe fitting including a plate having a portion adapted to be attached to the discharge passageway of said bowl, the opposite end of said fitting comprising a normally vertical stack, means preventing the leakage of sewer gas through the Joint in the discharge passageway, said pipe fitting including a siphon of constant length intermediate the ends thereof, means operable through said plate for cleaning said siphon, means for admitting a flushing liquid into said bowl, and means for directing an auxiliary stream upwardly into said siphon.

'7. A pipe fitting including a trap, a stack and vent pipe, a securing plate forming an integral part of and being a terminal of said fitting, said stack comprising the opposite terminal of said fitting, said trap and said vent pipe being permanently secured to said stack, and a jet opening into said trap in an upwardly disposed direction.

8. A pipe fitting including a trap and vent pipe, said trap and vent pipe being adapted to be concealed within a conventional partition, the length of the pipe forming said trap being fixed, a securing plate forming an integral part of said fitting, a plurality of anchor bolt receiving recesses in said securing plate, and a jet opening into said trap in an upwardly disposed direction.
