Description

FIELD

The present invention generally relates to wall sillcocks and, more particularly, to an exposed pipe wall sillcock with one or more side inlets for installation without miscellaneous mounting hardware and fittings, and which may include an integral stop, which allows the valve to be shut off and serviced without shutting off the water to the entire system.

BACKGROUND

Hose bibbs or sillcocks are generally known in the art. A typical installation includes outdoor connections in mild climates or any indoor installation for residential, commercial, institutional and industrial applications. In outdoor installations, such as a parking garage, these sillcocks are positioned along the walls at desired locations with the water pipes exposed. The sillcocks may be connected together from a common water supply. Sillcocks of the kind used in these applications are typically provided with a spout having standard hose-coupling threads to receive commercially available hose couplings. Because prior art sillcocks have the water connection inlet in the back, plumbers have to use an elbow or tee fitting to connect the sillcock to the water pipes which run against the wall. This leaves the sillcock extending out into space away from the wall, which not only is visually objectionable, it is a hazard to people, vehicles, and the sillcocks as they are unsupported. Because it is not inherently secure, plumbers have to variously construct ways to mount these sillcocks. Often plumbers have to cobble together some kind of mounting using Unistruts, clamps, and brackets to secure the sillcock.

In a multi-sillcock water supply installation, such as a parking garage, if one of the sillcocks requires maintenance, water to the entire system needs to be turned off while maintenance is under way. By way of example, assume that a parking garage structure has five floors with the water supply entering the structure on the first floor. Assume that each of the floors has four sillcocks mounted to four opposite exterior walls and are all ganged together. Further assume that one of the sillcocks on the fifth floor is leaking and requires service. The plumber will first have to go to the first floor to turn off the water to the entire structure. The plumber will then have to carry his/her tools to the fifth floor to service the sillcock. Once the repairs are completed on the fifth floor sillcock, the plumber will then have to carry his/her tools to the first floor to turn the water back on. The plumber will then have to carry his/her tools back to the fifth floor to check the fifth floor sillcock for leaks. Assuming that the sillcock was correctly repaired, the plumber may then have to purge air from the other 19 sillcocks in the system. While the maintenance is in progress, the other sillcocks on other floors of the structure cannot be used until the maintenance is completed.

Prior art sillcocks, which include a single inlet and single outlet require multiple fittings in order to gang multiple sillcocks together in a water system, increasing installation and maintenance costs.

Accordingly, there is a need for a sillcock that includes one or more side inlets and may be isolated in a multi-sillcock common water source installation.

SUMMARY

The present invention includes a sillcock with one or more side inlets which allows the sillcock to be mounted directly to a wall or other structure without additional fittings such as an elbow or tee. Multiple inlets allow the sillcock to be used in a system of sillcocks coupled or ganged together. Typical applications include outdoor connections in mild climates or any indoor installation for residential, commercial, institutional and industrial applications. The present invention may include one or more side inlets to allow secure mounting to the wall. Multiple inlets allow for convenient coupling to other sillcocks in a water system. Additionally, the present invention may include an integral stop, which allows the sillcock to be shut off and serviced without shutting off the entire system.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims, and as a representative basis for teaching one skilled in the art to variously understand and employ the present invention in virtually any appropriately detailed structure.

Referring to FIGS. 1-9, a sillcock of the present invention is generally indicated by reference numeral 10. Sillcock 10 includes a body 12 with two inlets 14 and 16, an integral stop 18, and a valve shut-off 20 with an outlet 22. The inlets 14 and 16 may include internal pipe threads 24 and 26, respectively, to receive one end of externally threaded water pipes or a threaded plug (not shown). Although illustrated with pipe threads, inlets 14 and 16 may include any other type of joint such as straight threads, solder or push-fit, for example. Additionally, in a two-inlet configuration, the inlets 14 and 16 may be coaxial as shown in FIGS. 1-9, or they may be in a 90-degree configuration.

The integral stop 18 includes an elongated adjustable stem 28, a seat washer 30 secured to the stem 28 by a bibb screw 32 and a retaining nut 34. The elongated adjustable stem 28 includes external threads 29, and is received in the retaining nut 34 engaging internal threads 31, and sealed by O-ring 36. The retaining nut 34 has external threads 35 and is received in the valve body 12, engaging internal threads 37 and sealed by O-ring 38. Rotation of the adjustable stem 28 translates the stem 28 longitudinally within the nut 34, which allows the seat washer 30 to open or close the channel 40 from the inlets 14 and/or 16 to the valve shut-off 20. When the integral stop 18 is closed by rotating the stem 28 clockwise, the seat washer 30 is seated against an internal surface 42 of the valve body 12 blocking an aperture 44 and preventing water 45 from entering the channel 40. When the integral stop 18 is opened by rotating the stem 28 counterclockwise, the seat washer 30 is moved away from the internal surface 42, opening the aperture 44 and permitting water 45 to enter the channel 40 to the valve shut-off 20. (See FIGS. 4, 8 and 9).

Valve shut-off 20 may include a stem 46, a seat washer 48 secured to the stem 46 by a bibb screw 50, a stem packing 52 and washer 54, a valve stem cap 56 and an operator handle 58 secured to the end of the stem 46 opposite the seat washer 48 by a handle screw 60. The valve stem cap 56 includes internal threads 57, which engage external threads 59 of the valve body 12 to secure the valve shut-off 20 to the valve body 12. The outlet 22 may include a check spider 62, a washer 64 and a threaded hose bibb 66 secured to the valve body 12. The operator handle 58 is rotatable to longitudinally translate the stem 46 within the valve shut-off 20 to open and close the valve shut-off 20. It should be understood that operation of the valve shut-off 20 is not limited to an operator handle 58 as shown, and may include a loose key, lever, or other means to rotate the valve shut-off 20.

The valve body 12 includes a longitudinal axis 13 and a mounting plate or flange 68 for mounting the sillcock 10 to a wall or other structure. The mounting plate or flange 68 may present a planar surface generally perpendicular to the longitudinal axis 13 of the valve body 12 for mounting the sillcock 10 to a surface. It should be understood that the valve body 12 may not include a mounting plate or flange, presenting a back surface of the valve body 12 as indicated by reference numeral 69. The inlets 14 and 16 each include a longitudinal axis 15, which may be directed in any direction in a plane generally parallel to a mounting surface of the mounting plate 68 of the sillcock 10, and spaced between the mounting surface and the valve shut-off 20.

Referring to FIGS. 10 and 11, another embodiment of a sillcock of the present invention is generally indicated by reference numeral 70. The sillcock 70 includes the same parts as described above for sillcock 10 with the base 72 having four inlets 74, 76, 78 and 80. The integral stop 82 is located forward of the four inlets. A threaded plug 84 may be inserted into any inlet that is not being used for a particular installation. Sillcock 70 allows additional flexibility in routing water pipes vertically and horizontally as desired, securely fastened to a wall or other structure without having to cobble together mounting struts and clamps. Additionally, sillcock 70 may be installed without elbow or tee fittings, saving time and money, and reducing maintenance.

Referring to FIGS. 12-15, another embodiment of a sillcock of the present invention is generally indicated by reference numeral 90. Sillcock 90 includes many of the same parts described above for sillcock 10. Sillcock 90 includes a two-part body, base 92 and valve 94 rotatably joined together about a sealed joint 96. The base 92 includes inlets 14 and 16, mounting plate 68, and integral stop 18. The base 92 may be rotated in either direction relative to the valve 94 about the sealed joint 96. A set screw 98 or other fastener may be employed to secure the valve 94 and base 92 together at a desired position. Sillcock 90 allows additional flexibility in installation using a single sillcock. For example, a sillcock 90 of the present invention having one inlet may be mounted with the inlet directed upwardly, downwardly, to the left or to the right. Similarly, a sillcock 90 with two coaxial inlets may be mounted with the inlets positioned vertically to connect to water lines 100 and 102, or horizontally to connect to water lines 104 and 106.

Referring to FIG. 16, a structure 110 is illustrated with three floors. Three sillcocks 10A, 10B and 10C of the present invention are illustrated mounted to a wall 112. The three sillcocks 10A, 10B and 10C are connected to a common water line 114, which enters at the lowest level and proceeds upwardly along the wall 112 and through the floors 116 and 118 connecting each of the sillcocks 10A, 10B and 10C. The water line 114 is connected to both the bottom and top inlets of sillcocks 10A and 10B and to the bottom inlet of sillcock 10C. A threaded plug 84 is installed in the top inlet of sillcock 10C. If any of the sillcocks 10A, 10B or 10C require servicing, such as to replace the packing or a washer, it is only necessary to close the integral stop 18A, 18B or 18C for that individual sillcock with the other sillcocks remaining usable and in service. Further, when the repaired sillcock is to be placed back in service, it is only necessary to open the integral stop 18A, 18B or 18C for that particular sillcock. Each sillcock 10A, 10B and 10C may be serviced independently without a service technician having to locate a water supply shutoff; turn off the water supply to the structure; carry his/her tools to the sillcock to be serviced; service the sillcock; carry tools back to water supply shutoff; turn the water back on for the structure; go back to the serviced sillcock to check for leaks; and then bleed the system of trapped air.

Referring to FIGS. 17-18, a sillcock of the present invention is generally indicated by reference numeral 120. Sillcock 120 includes a body 12 with one inlet 14, and a valve shut-off 20 with an outlet 22. The inlet 14 may include internal pipe threads 24 to receive one end of externally threaded water pipe. Although illustrated with pipe threads, inlet 14 include any other type of joint such as straight threads, solder or push-fit, for example. While shown extending from the top of the sillcock 120, inlet 14 includes a longitudinal axis, which may be directed in any direction in a plane generally parallel to a mounting surface of the mounting plate 68 of the sillcock 120, spaced between the mounting surface and the valve shut-off 20. The sillcock 120 may include two or more inlets as described hereinabove. The other features of the valve shut-off 20 are as described in detail hereinabove.

In a typical installation, the sillcock of the present invention is mounted directly to a wall of a structure, fully supported and secured flush against the wall. No additional mounting fixtures, supports or brackets are needed for the installation. Likewise, because the one or more inlets are on the side of the sillcock of the present invention, the waterlines are coupled directly to the sillcock without use of elbows or tees. The flexibility of the novel sillcock of the present invention permits installation without the need for additional parts, brackets or fixtures for each sillcock installation. The sillcock of the present invention eliminates the cost and inconvenience of installing a sillcock with a rear-entry inlet. The flexibility of the sillcock of the present invention, whether having fixed inlets or rotatable inlets, simplifies installation and improves the security and safety of the overall water system. Further, the ability to shutoff individual sillcocks reduces maintenance costs of the system, and increases the availability of the system when a sillcock is being serviced.
