Abstract: An internal back vent system which includes a single vertical stack divided by concentric vertically disposed vent and drain pipes into a main central drain or waste passageway surrounded by an annular vent passageway. Adjacent the floors to be serviced, the vertical stack is provided with manifold assemblies which interconnect the ends of branch waste pipes to the main drain passageway while venting each branch pipe to the vent passageway. The manifold includes a plurality of radially extending connector pipes all communicating with the main drain passageway. These outwardly extending connector pipes are respectively connected to the branch waste pipes which form the drains of the various fixtures within the building. At each level, a corresponding number of upstanding, relatively short, vent pipes are disposed, circumferentially spaced, in the annular vent passageway and are respectively connected by their lower ends to the connector pipes.

Abstract: A water closet carrier of the type which supports an off-the-floor toilet, the carrier having a pair of upstanding slotted brackets which support a vertically disposed face plate, selectively positionable in angularly related positions with respect to the brackets. Racks along the inner surfaces of the slots cooperate with pinion nuts on the mounting studs of the face plate for vertically positioning the face plate. A branch pipe projects through the face plate and is clamped by an encircling strap to tabs projecting from the face plate. The pipe, in turn, is clamped, by an O-ring and a compression plate, to the discharge port of the toilet carried on the opposite side of a wall by the mounting studs.

Abstract: A machine and method disclosed for stacking articles adjacent the end of a conveyor having angularly conjoined article panels. The machine comprises a pair of endless chains mounted for orbital movement about opposite sides of a flight path extending from the end of the conveyor. Drive means are provided for orbiting the chains. Stop means are mounted to each of the chains for stopping articles received from the conveyor. Dog means are mounted to the chains adjacent the stops for engaging one of the article conjoined panels in propelling articles received from the conveyor along the flight path. Prop means are also mounted to each of the chains adjacent the dog means for engaging another of the article conjoined panels in at least partially supporting the articles as they are propelled along the flight path.

Abstract: A hanger assembly for pipe joints which includes a pipe joint coupling and a removable stabilizer for connecting the coupling to the hanger bar. The stabilizer includes a saddle sandwiched between the shield and the clamping bands of the coupling. The shield, in turn, surrounds the resilient sleeve into which the ends of the pipes project. The saddle is formed from a pair of thin arcuate saddle plates, the outer edges of which are provided with outwardly projecting alignment tabs.An outwardly projecting flat lug on the saddle is formed from a pair of flat rectangular opposed lug elements joined at their distal ends along a common edge and respectively joined to the saddle plates at their proximal ends. The lug has a hole for receiving a securing bolt which passes both through the lug and through an eyelet, at one end of the hanger rod. The other end of the hanger rod is anchored to the supporting structure.
