    摘要: The present invention provides a plumbing apparatus that includes an offset or tangential T-fitting providing for offsetting a branch pipe from a run pipe in end elevation view, and for the branch pipe to intersect the run pipe orthogonally in side elevation view. That is, the branch pipe may intersect the run pipe substantially tangentially, so that an arrangement of plumbing fittings and devices may be nested into a thinner wall or into a smaller dimension of space than would be the case if a conventional T-fitting were employed. By use of the inventive T-fitting a considerable savings in materials of construction may be realized in the construction of swimming pools and spas, for example. Particularly, the present inventive offset or tangential T-fitting provides for the installation of bubble jet fittings and associated piping into a comparatively thin (i.e., about 6 inches thick) dam wall between a swimming pool and spa.

    摘要: A thread cutting milling tool comprises a shank with a working portion formed with a recess for receiving a thread cutting insert. The thread cutting insert has one edge formed with a line of thread-form teeth of identical profile. The thread cutting teeth project laterally for cutting engagement with a work-piece while the tool spins about its axis. The tool also orbits within or about a work piece, and in one orbit of the tool in a helical cutting path relative to the work piece a number of complete turns of the screw-thread are formed which is equal to the number of teeth of the insert in engagement with the work-piece. A secondary cutter carried on the thread cutting milling tool provides for formation of a pilot portion or counter bore on the work piece at an end of the screw thread. The pilot portion or counter bore provides for alignment of a threaded member which is to engage the screw thread. Also, the secondary cutter provides for formation of a blunt or scalloped full-thread starting end for the screw thread at the pilot portion. The blunt starting end for the screw thread is robust, resists damage, and resists cross threading.

    摘要: A bubble jet fitting for use in a pool or spa provides for a lay-length short enough to allow its installation within a six-inch dam wall. The bubble jet fitting has an outlet portion which in one use provides for solvent welding therein of either one of two different standard sizes of PVC pipe. An axially extending annular recess of the fitting may receive a surfacing layer of plaster or fiberglass to form a water-tight interface with the surrounding wall of the pool or spa.

    摘要: An improved, non-conductive electrical junction box includes a wall defining an insert recess. An insert member is received into the insert recess and defines a conduit socket in order to provide for an end portion of an electrical conduit to be joined with the junction box, providing for electrical wiring to pass between the conduit and the junction box.
