JET ACTION CROSS T FITTING Filed Sept. 6. 1957 INVENTORS James Fraser BY Edam-J 15f IWLLean A TTORNE Y5 United States Patent JET ACTION CROSS T FITTING James Fraser and Edward S. McLean, Wilmington, Del., assignors to Speakman Company Application September 6, 1957, Serial No. 682,502
3 Claims. (Cl. 103-262) This invention relates to a cross T fitting. More particularly it relates to a jet action fitting to be placed within the common junction of the hot and cold water inlets and the outlets to the shower and bath.
Heretofore the shower arranged above the bath tub has been connected to the cold and hot water inlets and an extension of the shower supply conduit has led to the tub faucet. When it is desired to operate the shower a closure has been operated within the faucet forcing the water back up the shower supply conduit. The difficulty experienced with this type of supply system has been that the shower has a tendency to discharge water when the tub faucet is open. Many devices have been constructed to overcome this difficulty. All of these devices require an intricate molding operation in forming the cross T with connecting conduits molded therein.
It is an object of the present invention to provide a cross T fitting that will positively remove any water in the shower conduit when the tub faucet is in operation.
It is a further object of the present invention to provide a jet action fitting within the cross T that will syphon water from the upper discharge outlet into the lower discharge outlet when the lower outlet is open.
It is a still further object of this invention to provide a fitting in a cross T connection that is constructed outside of the cross T and then inserted therein.
The various features of novelty which characterise this invention are pointed out with particularity in the claims annexed to and forming part of this specification.
For a better understanding of the invention, however, its advantages, and specific objects obtained by its use, reference should be had to the accompanying drawings and descriptive matter in which are illustrated and described a preferred embodiment of the invention.
Of the drawings:
Fig. 1 is an outside elevational view of a cross T.
Fig. 2 is a plan view on line 22 of Fig. 1.
Fig. 3 is a plan view on line 33 of Fig. 1.
Fig. 4 is a sectional view on line 4-4 of Fig. 2.
Fig. 5 is a perspective view of the cross T fitting shown in Figs. 3 and 4, without the conduit.
Fig. 6 is a top view of the second modification of this invention.
Fig. 7 is a side view of the fitting shown in Fig. 6.
Fig. 8 is a bottom view of the fitting shown in Fig. 6.
Fig. 9 is a sectional view on line 9-9 of Fig. 6.
Fig. 10 is a sectional view on line 10-10 of Fig. 7.
A cross T 20, shown in Fig. 1, has a hot water inlet 21 and a cold Water inlet 22. This cross T has an outlet 23 to the shower head and an outlet 24 to the bath tub nozzle connected thereto. Within this cross T is located a fitting shown in detail in Fig. 4, which comprises a plate 25 with a conduit 26 therethrough. The upper portion of the conduit 26 is threaded to fit in the lower portion of the outlet 23 and effectively seals this outlet, except for the opening 27 within the conduit. This conduit extends down into the outlet 24 substantially below the point of entry of the hot and cold water through the inlets 21 and 22. A ring 28, shown in Figs. 4 and 5, is fastened to the conduit 26, as shown in Fig. 5, and lies against the inner walls of the lower outlet as shown in Figs. 3 and 4. The lower part of the conduit 26 has a hexagonal inner wall 29 which allows the insertion of a tool therein, which facilitates screwing this device into position. The water entering through the inlets 21 and 22 flows, as shown in Fig. 4, around the outside of the conduit 26 and is restricted by means of the ring 28. It then expands around the end of this conduit into the out let 24 thereby creating a syphon jet action downwardly in the opening 27 of the conduit 26. Since this conduit is held in water-tight engagement with the opening of the upper outlet 23, this gives a positive method of removing residual water from the upper outlet 23. If the nozzle connected to lower outlet 24 is closed the water will then flow upwardly through the conduit 26 and out the opening 27 into the upper outlet connected to the shower head.
A second modification of this invention is shown in Figs. 6, 7, 8, 9 and 10 wherein the conduit 26a has an upper opening 27a similar to the device described above. The walls of this conduit are threaded on the upper end to permit insertion within the cross T in the same manner as in the first modification. A plate 25a is connected to the upper part of the conduit 26a and elfectively closes the upper outlet 23. A second plate 30 lies below the plate 25a and has its water passages 31, 31, connecting with the inlet through a recessed marginal portion 32 (shown in Fig. 7), lying between the upper plate 25a, closing the upper outlet and the lower plate 30 closing the lower outlet. When this is inserted within the cross T shown in Fig. 4, the water flows around the recessed marginal portion 32 through the water passages 31 and around the central conduit 26a into the outlet 24 through the opening 33, between the plate 30 and the conduit 26a, so as to create a jet action within this conduit which gives a positive method of removing the residual water from the shower outlet 23. The upper portion of the central conduit has a hexagonal form to the inner wall which allows the insertion of a tool to screw this device into position within the cross T.
While in accordance with the provisions of the statutes, there has been illustrated and described the best form of embodiment of this invention, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of this invention as set forth in the appended claims and that in some cases certain features of this invention may be used to advantage without a corresponding use of other features.
What is claimed is:
1. A cross fitting comprising two horizontal inlets and opposed upper and lower outlets all having a common junction, an aspirating fitting within said opposed outlets across the two inlets, comprising a body portion closing said upper outlet and having a conduit therethrough connecting the two outlets and a ring portion surrounding said body portion in engagement with the wall portion of said lower outlet, a fluid passage between said ring portion and said conduit.
2. A device as claimed in claim 1, wherein said ring portion has a tapered wall to force the water towards the conduit.
3 4 3. A cross fitting comprising two horizontal inlets and subtended below the upper plate and forming a fluid opposed upper and lower outlets, all having a common passage between the two plates and around said conduit.
