Abstract
A kit for installing a bath spout onto any one of a number of different pipe ends extending from a wall is described and includes a number of adapters sized to enable different pipe ends to be coupled into a standard screw thread of internal conduit inside the bath spout. One adapter enables the screw thread of a pipe end to be effectively enlarged. Another adapter slips onto the smooth outer surface of a pipe and makes a sealing contact with this surface while having one end provided with an enlarged external screw thread to mesh with a corresponding screw thread of a conduit inside the bath spout. An inner conduit is described which in one embodiment is made of a number of inter-connectable segments with which the length of the inner conduit can be adjusted and in another embodiment the inner conduit is formed of a single unitary structure with a several screw threads at a distal end to be able to adjust the length of the inner conduit with the removal of the distal thread.
Description




FIELD OF THE INVENTION




This invention generally relates to bath spouts and more particularly to a kit for enabling a bath spout to fit with a wide variety of pipe connections.




BACKGROUND OF THE INVENTION




Bath spouts typically have a shell surrounding a central conduit through which water flows for use in the bath. The conduit requires a fitting to connect to a feed pipe extending from a wall adjoining the bath. This feed pipe, also known as a nipple, may have typical dimensions and end finishes such as a ¾ pipe with a ¾ or ½ threaded end, a ½ inch pipe with a threaded or smooth pipe end.




There are devices with which a bath spout's inner conduit can be mounted to ¾ or ½ inch threaded pipes. A need exists whereby a single kit can provide an installer with the connection capabilities suitable for most typical wall pipe ends.




SUMMARY OF THE INVENTION




In one universal and adjustable bath spout kit in accordance with the invention a spout shell is provided with a wholly or partially replaceable inner conduit to which one of several different adapters can be affixed to couple the inner conduit to a pipe nipple extending from the wall. The kit includes a metal or plastic spout shell having an internal end wall with a discharge port therein through which water is passed to a typically downwardly directed spout opening. An internally threaded coupling is positioned inside the spout shell over the discharge port and serves to enable an installer to insert the inner conduit. The inner conduit can be formed of a plurality of connectable plastic fittings that are screwed together to control the length of the inner conduit.




Alternatively the inner conduit can be made of a unitary plastic part. This part has a proximal or wall end where an adapter for attachment to the pipe nipple can be threaded. At a distil end the unitary inner conduit is provided with first and second external spaced apart screw threads each of which mesh with the threaded coupling inside the spout shell. Hence, when the inner conduit needs to be shortened, because a particular adapter is axially too large to enable a substantially flush fit of the spout shell with the wall, the distal screw thread on the inner conduit can be removed by cutting it off to shorten the inner conduit while leaving the second thread for attachment to the internal coupling.




When the inner conduit is formed of a single unitary part its cost can be significantly reduced and the various adapters necessary to accommodate the bath spout kit to various wall nipples as may be encountered in the field can be used while enabling a flush fit of the spout shell against the wall from which the pipe nipple extends.




As described herein for one embodiment in accordance with the invention the bath spout kit includes an inner conduit formed of a plurality of interfitting threaded segments with which the length of the inner conduit can be adjusted. This length adjustment is needed to enable the installer to assure a sealed connection with the pipe extending from the wall while having the enclosing spout shell fit essentially flush with the wall from which the pipe extends.




It is, therefore, an object of the invention to provide a universal bath spout kit with which an installer can adapt the spout to anyone of a variety of pipe ends.




It is a further object of the invention to provide a universal spout kit with adjustable features to facilitate the installation of a bath spout.




These and other objects and advantages of the invention can be understood from the following description of a preferred embodiment as shown in the drawings.

DETAILED DESCRIPTION OF DRAWINGS




With reference to FIGS.


1


-


6


a bath spout shell


10


is shown for use in a kit


12


in accordance with the invention. The bath spout shell


10


can have many different shapes as are well known in the art and the particular shell


10


is shown for illustrative purposes. The shell


10


, is shown with an internal conduit generally indicated at


14


and which is installed starting at an internally threaded metal bushing coupling


16


at a discharge port


18


leading to the discharge opening


20


of the spout shell


10


.




A nylon or other plastic externally threaded male to male fitting


22


engages the internally threaded bushing


16


with an externally threaded segment


23


.


1


and has another externally threaded segment


23


.


2


. The fitting


22


is provided with an opening


24


for a shower connector


26


. A flexible shower hose


28


, as illustrated in phantom at


28


, can be coupled to connector


26


. This shower connector


26


need not always be a part of the shell


10


since shower installations are typically already a part of the plumbing coupled to a wall nipple


30


to which the bath spout is to be connected. The same optional feature applies to the use of the manual water deflector


32


and connected seal


33


located on the end of the spout shell


10


.




The internal conduit


14


extends towards the front or proximal end of the shell


10


. The conduit


14


includes an intermediate coupling


35


and an end coupling


36


having female internally threaded segments


38


.


1


and


38


.


2


one of which is sized to mesh with and fit over threaded male segment


23


.


2


of the fitting


22


. These various inter-meshing couplings


22


,


35


,


36


are interconnected in such manner as to adjust the overall axial length of the inner conduit


14


. This length is adjusted to accommodate the various different lengths of adapters that are used at the proximal or wall end of the inner conduit for attachment to the wall pipe


33


.




In the kit


12


, the internal threaded portion of bushing


16


has a ½ inch diameter, the male segments


23


.


1


and


23


.


2


have a ¾ inch diameter and the female end coupling


36


has a corresponding meshing size for its female threaded segments


38


. The kit


12


is made to fit with different wall pipe nipples


30


, such as a ¾ inch externally threaded nipple


30


.


1


, a ½ inch threaded nipple


30


.


2


, a straight pipe end


31


.


1


and a ½ inch extended threaded pipe end


31


.


2


. In order to be able to adapt the bath spout


10


to anyone of the nipples


30


and to pipes


33


having pipe ends


31


, adapters


40


and


42


are provided.




Adapter


40


is a diameter reducer as viewed from the % size of the threaded female segment


38


.


2


. Adapter


40


has a ¾ external thread


43


.


1


and has a ½ inch internal thread


43


.


2


. Hence, adapter


40


can fit around nipple


30


.


2


and inside thread


38


.


2


to enable the bath spout to be coupled thereto.




A slip fit adapter


42


is provided with a smooth internal bore


44


sized to smoothly fit over the smooth ½ inch pipe end


31


.


1


. Bore


44


has a groove


45


sized to receive an O ring


46


sized to sealingly contact the external surface of the smooth ½ inch pipe end


31


.


1


. The slip fit adapter


42


has, at one end, a flange


48


with at least one threaded hole to receive a set screw


50


with which the flange can be affixed in place on pipe end


31


.


1


. At the other end of the flange is a ¾ external thread


52


to mesh with that inside the female segment


38


,


2


inside the spout shell


10


. Adapter


42


can also be used to couple the pipe


33


.


2


with the threaded pipe end


31


.


2


. This typically involves a cutting of the pipe


33


.


2


to the desired length, such as pipe end


31


.


1


, and then attaching the slip fit adapter


42


. Alternatively, the pipe


33


.


2


can be directly affixed to fitting


16


after first removing the conduit


14


. Such removal is readily accomplished after first removal of the side coupler


26


when it is used, and then unscrewing the conduit


14


from fitting


16


.




Kit


12


may include accessory articles such as an alien wrench


60


for set screw


50


and a roll of suitable sealing tape


62


.




With reference to FIGS.


6


-


10


an alternate design for an inner hollow conduit


80


for use with a bath spout kit


82


is shown with a through bore


81


. The inner conduit


80


is formed of a unitary elongate plastic part with a ¾ inch thread receptacle


84


, similar to segment


38


.


2


shown in

FIG. 2

, at a proximal end


86


and a pair of external axially spaced apart threads


88


,


90


at a distal end


92


of a cylindrical shank


93


. The threads


88


,


90


are identical and mesh with the thread inside the coupling


22


inside the bath spout shell


10


or an extension thereof. The extension can be provided by the segment


22


in

FIG. 1

to enable a shower adapter to be connected as described. The threads


88


,


90


are separated by a short smaller diameter portion


94


, which is just sufficiently axially wide to enable one to sever the inner conduit


80


at portion


94


and leave the remaining thread


88


in tact with its starting thread


96


.




The axial length of the distal thread


90


is selected so that when an axially long adapter, such as the slip adapter


42


, is applied to the proximal end


86


as illustrated in

FIG. 9

, the inner conduit


80


normally would be too long and the slip adapter would stick out of the wall end


83


of the bath spout


10


. Accordingly, the installer would cut the inner conduit


80


along a radial plane represented by line


98


and as a result sever the distal threaded portion


90


from the inner conduit as shown in FIG.


10


. Since the remaining thread


88


is identical to thread


90


, the thread


88


can serve to connect the inner conduit


80


to internal coupling


22


or an extension thereof and the now shortened conduit would enable the slip fit adapter


42


to fit inside the bath spout


10


as illustrated in FIG.


9


.




With an inner conduit


80


the multiple couplings


22




35


and


36


for the embodiment shown in FIGS.


7


-


10


can be combined into a single structure, thus reducing costs, simplifying the kit


82


and the installation of the bath spout


10


.




In case where a shower adapter coupling


26


, as shown in

FIG. 3

, is used, the inner conduit


80


′ as illustrated in

FIG. 11

has its shank


93


′ shortened to accommodate a coupling


100


for connection to a shower connector


26


. The coupling


100


in effect provides an extension of the inner threaded bushing


16


and has an opening to receive a shower connector


26


through an opening


17


in bath spout shell


10


. The coupling


100


thus has a threaded end


102


that meshes with the thread inside bushing


16


and has a threaded counterbore


104


to receive the threads


88


,


90


of inner conduit


80


′.




Having thus explained a novel kit for affixing a bath spout to wall pipes of different sizes, various changes can be considered by one skilled in the art without departing from the scope of the invention. For example, the wall pipes can have different sizes as described herein and thus the corresponding thread sizes also changed. The invention is described for use with a bath spout, though it is to be understood that other water faucets can be accommodated and that the term bath spout as used herein, therefore, includes all such otter water faucets.
