detailed description

Referring now to Figures 1, 10, an integral open-cell saddle card pipe joint fitting is shown, preferably formed of a plastic plastic material, including an axially extending tubular connection with a flange 26 for coupling the outlet. Element 20, and a shaft 30. The unitary fitting 10 also includes a tubular saddle card member 22 having two opposed shoulder members 24. A shaft 15 is disposed within the pipe saddle card member. As shown in Figure 1, the pipe saddle card fitting has a curved surface 16 that is adapted to seat the fitting in a main conduit 18. In the installed position, the shaft 15 of the saddle card member 22 extends in a direction substantially parallel to the axis of the main duct 18. The shaft 30 of the tubular connecting member 20 extends orthogonally to the shaft 15 of the tubular saddle card member 22, i.e., extends outwardly from the saddle card member 22 and the main duct 18. The tubular joint 20 defines a passage 12 extending from the central opening of the tubular saddle card 22 and through which a medium flowing in the conduit 18 can enter the tubular connecting member 20 from a hole in the conduit 18.

As seen in Figure 1, it is also seen that the saddle card member 22 has a shell-like upper half 14 with an inner surface 16 extending circumferentially about 180 degrees. The circumferential inner surface 16 is arranged to extend around the circumferential portion of the main duct 18 and to extend in the axial direction of the main duct 18. The circumferentially extending inner surface 16 of the shell section 14 extends at an angle, specifically such that the pipe joint fitting 10 is radially disposed about the axial direction of the pipe 18. Preferably, the saddle card member 22 has a sliding fit to the conduit such that when placed on the conduit 18 a snap or hold action is created. Accordingly, in the installed position, the pipe saddle card member 22 extends in a direction substantially parallel to the pipe axis, and the tubular member 20 is disposed orthogonally to the pipe saddle card member 22. A bolt hole 27 is provided in the open flange ring 28 to facilitate the attachment of the flange 26 to a branch conduit (not shown) having a similar end connection.

Referring now to Figure 2, like reference numerals are used in the parts of the fittings shown in Figure 1. An opening 29 in the conduit 18 and an opening in the saddle card member 22 are shown to cooperate with the tubular member 20 to form a fluid passage region 12. The fluid passage region 12, including the tubular member 20, opens from the inner surface 17 of the saddle card member 22 to surround the opening connection opening 29 formed in the conduit 18. The diameter of the opening of the main conduit 18 may be equal to the nominal inner diameter of the main conduit 18, or the opening 29 may be reduced in size and smaller than the inner diameter of the main conduit 18. The channel region 12 is generally round in cross section orthogonal to the axis 30.

Figure 3 shows the prior art in which two separate fittings are used to form a branch pipe connection. In this prior art solution, an outlet joint 21 having a flange 19 is fused to a branch saddle card 23, and a fusion combination of the joint 21 and the saddle card 23 is attached to the duct 18. With this arrangement, however, the distance of the flange 19 to the main conduit 18 (as indicated by dimension A) is too long to use a standard size commercially available pressure tapping tool.

Figure 4A shows a prior art underfilled saddle-shaped card fitting, and correspondingly, the hot-melt contact region 16 is also insufficient, and the full pressure level of the joint is obtained when attached to a main pipe. Figure 4B shows a feature of the present invention that provides the necessary hot melt zone 16 and solids 12 to achieve an equivalent gauge pressure level in the base zone that is equal to the unperforated main pipe.

The overall product of a simple molded branch saddle card fitting 10 can be affected by the plastic material of the injection molding process. Alternatively, the product of the fitting 10 can be obtained by processing from a suitable plastic material. The plastic material of the selected apertured saddle card assembly 10 selected should be compatible with the fluid being transported by the pipe to be opened. Alternatively, it may be formed of a synthetic resin material such as a thermoplastic. Suitable thermoplastic materials include olefin polymers and general solid, moldable polyamide polymers wherein the preferred olefin polymer is a high density polyethylene and the preferred polyamide polymer is nylon.

The use of the open-hole saddle-card pipe joint fitting 10 is first firmly attached to the main plastic pipe 18 to be opened by a suitable method such as heat melting or electric melting. For example, the joint 10 can be attached by fusing the saddle portion 22 of the plastic joint 10 to the main pipe 10 by using an electric soldering iron or the like. Such as The aforementioned electrofusion or solvent bonding can also be employed, and a standard pressurized opening tool is attached thereafter. Additional accessories for the plastic saddle card 22 to the main plastic pipe of the soldering iron have found wide application. The soldering iron typically has a curvature that complements the curvature of the fitting to help simultaneously heat the surface of the saddle card 22 and the main plastic conduit 18 until the plastic at the interface of the two surfaces softens and melts. When sufficient softening or melting has occurred, the soldering iron is removed, and then by cooling, the saddle card 22 of the fitting contacting the pipe 18 is directly fused to the main pipe 18.

Referring now to Figure 5, like reference numerals are used in the fitting portion shown in Figure 1, in which a standard commercially available pressure tapping tool 40 and a plastic inserting saddle card fitting 22 are shown. The valve 42 is isolated and placed to insert a pressurized main conduit 18 through the conduit 18 by moving the cutter 42 forward. A mechanical joint as shown is used to connect the plastic fitting 22 and the metal isolation valve 42. The mechanical joint includes a rubber washer 44 and a pull bolt 46. Shown in Figure 5 is the flange connection between the pressure tapping tool 40 and the isolation valve 42 when any suitable connection between the components is satisfactory. Isolation valves and pressure tapping tools are used in the embodiment shown in Figure 5, each of which is a well-known part, available in different sizes and from a variety of suppliers.

The present invention has been described with reference to a standard pressure tapping tool for metal pipe fitting sizes and which can be used in conjunction with the novel open hole saddle card of the present invention for plastic pipe openings. It will be apparent to those skilled in the art from this <RTIgt;

The present invention has been described with reference to the specific illustrative embodiments, and is not limited by the scope of the appended claims. It will be appreciated by those skilled in the art that the embodiments of the invention can be modified and modified without departing from the scope and spirit of the invention.
