Abstract: A tub box for receiving a drain trap is formed from two substantially identical plastic housing portions each including one or more round knockouts in one or more side walls of the housing portions and one or more edge flange knockouts in an edge flange of each housing portion and side walls in line with and terminating in close proximity to the respective round knockouts. Pull tabs on the round knockouts facilitate removal of the round knockouts from the housing portions and limit the amount of nesting of the housing portions inside one another when stacked for storage and shipment so the housing portions can easily be pulled apart when desired. A lip protrudes axially outwardly from the radial outer edge of the edge flange of each housing portion around one half only of the periphery of each edge flange for overlapping engagement with the outer edge of the edge flange of an other housing portion when the edge flanges of two housing portions are placed in engagement with one another.

Abstract: A full or half clamp for supporting a pipe from a mounting surface includes a plastic body portion having an arcuate recess with an arcuate length in excess of 180.degree. and opposite ends that are relatively thin and flexible to facilitate snap fitting of a pipe into the recess. A pivotable arm is integrally connected to the body portion of the full clamp by a hinge formed by a notch in an outer wall of the body portion. The arm includes an arcuate recess forming a continuation of the recess in the body portion when the arm is moved into engagement with the body portion. A plurality of circumferentially spaced, longitudinally extending plastic projections are provided on the inner wall of the recesses in both the body portion and arm for gripping the exterior surface of the pipe. One of the projections is located on the arm immediately adjacent the hinge to provide a well defined hinge line for the arm.

Abstract: A washing machine outlet box includes a housing having a bottom wall containing a first valve mount for a first shutoff valve of a first water supply line and a valve mount insert that forms a second valve mount for a second shutoff valve of a second water supply line. The valve mount insert is selectively positionable in any one of several openings in the bottom wall to accommodate the second water supply line. A drain pipe is connected to one of the openings in which the valve mount insert is not selectively positioned. A test cap forms a seal for the drain pipe opening. In this manner, the washing machine outlet box can accommodate different plumbing arrangements.

Abstract: A washing machine outlet box includes a bottom wall having a first drain port for a washing machine hose and a second drain port for a condensate line. Communicating with both drain ports is a common tailpiece integral with the bottom wall. The common tailpiece includes an outlet for connection to a drain pipe and wall sections defining a first passageway from the first drain port to the outlet and a second passageway from the second drain port to the outlet. This allows both drain ports to be connected to the drain pipe with only one solvent weld between the tailpiece and drain pipe.

Abstract: A water shut-off valve includes a valve body and inlet conduit molded out of a solvent weldable plastic such as CPVC. The inlet conduit has a threaded portion proximate the valve body to receive a nut used to secure the valve to a mounting bracket, and an integral extension at an outer end of the threaded portion having a smooth cylindrical surface which may be solvent welded to conventional plastic plumbing.

Abstract: A roof flashing for establishing a weather-proof seal with upstanding pipes of different diameters includes a frusto-conical shape collar having smaller diameter upper and larger diameter lower seals for sealingly engaging different diameter pipes and an internal annular groove immediately above the lower seal providing a frangible wall section in the collar to facilitate removal of the upper seal from the collar when the collar is to be used to seal against larger diameter pipes. Immediately below the internal groove on the exterior wall of the collar is an external annular bead which together with the lower seal resist stretching of the collar when engaged by a gripping tool immediately above the internal groove and pulled to provide a relatively clean tear in the region of the internal groove around the entire periphery of the collar to separate the upper seal from the collar.

Abstract: A roof flashing for sealing an opening in a roof through which an upstanding pipe extends includes a base member having an opening for passage of the pipe and a collar attached to the base member surrounding the opening in the base member for receipt of the pipe when the base member is attached to the roof. The collar has corrugations which permit the collar to be expanded and compressed to different lengths to accommodate different length pipes within the collar. The corrugations at the outer end of the collar are flattened out to facilitate folding of the outer end over an upper end of the pipe to form a watertight seal between the collar and pipe.

Abstract: A clamp for use both with sheet metal and softer structural members of a building such as plasterboard or wood to support a pipe or conduit in different size openings through the members, including an exterior tapered surface having helical threads to facilitate screwing of the tapered surface into such different size openings, and a central passage for the conduit. The clamp has a gap through one side along its entire length to permit the clamp to be opened to fit over a pipe or conduit. Diametrically opposite the gap is an internal slot which reduces the cross-section of the clamp to form a hinge. The clamp may also include an oppositely extending exterior smooth tapered surface positioned base-to-base with the threaded tapered surface and resiliently mounted barbs protruding radially outward beyond the smooth tapered surface.

Abstract: A food roller dispenser for dispensing the contents from a flexible pouch-like food container by passing the container between a pair of elongate rollers having teeth which mesh and overlap each other to drivingly grip the container between the meshed teeth and squeeze the contents from the container during counter-rotation of the rollers. Each of the rollers is of a solid one-piece plastic construction having roller bearing portions adjacent opposite ends which are removably captured in easily disassembled bearing blocks for ease of cleaning. One of the rollers is driven by a handcrank which, through a set of gears mounted on shaft extensions on the ends of the rollers, drives the other roller in the opposite direction.

Abstract: A roof flashing and method of making same in which both the collar and base member of the flashing are made of elastomeric material. The base member is molded first and has an opening therein surrounded by a stepped flange provided with a series of circumferential slots therein. The collar is molded onto the base member during a subsequent molding operation in which the material of the collar is injected through the slots and completely around the top, bottom and inner side edge of the flange to form a series of closed loops thus providing a positive mechanical lock between the collar and base member. Also, the heat of the elastomeric material of the collar during the second stage molding process causes some melting of the elastomeric material of the base member whereby the collar and base are also fused together.

Abstract: Dispenser system includes a pair of squeeze rollers for squeezing putty-like material from a bag-like container as the container is pulled between the rollers during turning of the rollers in opposite directions. Each of the squeeze rollers has a rubber-like cover whereby the rollers may be compressed together to ensure that the rollers will frictionally grip opposite sides of the bag passing therebetween to uniformly pull the bag between the rollers during turning of the rollers to squeeze the material out of the container. The container itself is preferably made from two flat sheets of plastic material which may be joined together by heat sealing. The two sheets are initially laid flat one on top of the other and heat sealed along the side edges and bottom which is formed into a funnel-shaped spout. The top is left open to permit filling of the container with the desired quantity of putty-like material.
