8 Claims.

This invention relates to plumbing fixtures, and more particularly to a valve and mixing spout assembly for wash basins.

A common form of valve and spout assembly for wash basins comprises separate spaced valves for hot and cold water and a common spout therebetween. The valves and spout are connected beneath the wash basin by short pieces of brass tubing the ends of which are compressed in suitable fittings. The discharge through the waste or drain pipe is controlled by a mechanical valve operated by means of a vertical drain control rod passing through the vertical center line of the spout. This in turn complicates the casting for the spout, it being necessary to provide an inner passage for the drain control'rod while the water supply flows in an annular space around the center passage. The primary object of my invention is to generally improve and-simplify valve and spout assemblies of this general character.

These assemblies as heretofore constructed are characterized by serious disadvantages. Considerable labor is required to install and properly connect the various separate parts of the valve and spout assembly. It is necessary to level up the valves and spout to fit the top surface of the basin. The pipe size used is rather small, say inch, and while this is adequate if unobstructed, it proves inadequate when obstructed, as by lamp wick, putty or other packing used in making the connections. The packing may be used freely to prevent leaks, for a subsequently developing leak is a serious matter. The parts are ordinarily in an inaccessible location when finally installed,

and many hours of labor may be needed to disassemble and re-assemble the fixture to eliminate a leak.

More particularized objects of my invention are to obviate the foregoing difficulties and disadvantages of conventional fixtures, and. to instead provide a substantially leak-proof fixture whichmay be quickly installed and which is not subjected to obstruction of the water flow therethrough.

To the accomplishment-of the foregoing general objects and other more particularized objects which will hereinafter appear, my invention consists in the valve, spout and drain control elements and their relation one to the other,.as hereinafter are more particularly described; in the specification and sought to be defined in the claims. The specification is accompanied by drawings in which:

1937, Serial No. 159,893

Fig. 1 is a plan view of a conventional basin I showing the application of my invention thereto; Fig. 2 is a section taken in elevation in the plane of the line 2-2 of Fig. 1;

Fig. 3 is a front elevation of the valve and spout assembly with the cover plate and handle removed from one of the valves;

Fig. 4 is a section through a modification of the invention in which the spout is securedin place by means of a slip connection;

Fig. 5 is a plan View of the end or the nipple or connection used in Fig. 4; and 7 Fig. 6 is a section taken in elevation through still another form of spout and nipple embodying features of the invention.

Referring to the drawings, and more particularly to Figs. 1 and 2, the invention is shown applied to a basin l2 which is conventional in having a bowl l4 surrounded by a ledge It provided with three spaced openings at the rear surface [8 thereof. A hot water valve 2|] is disposed in one of these openings, 2. cold water valve 22 in another of the openings, while a spout 24 is mounted in the third or center opening. The bowl [4 is drained through a waste or drain pipe 26, the drain being controlled by a-vertically movable disc valve 28 mounted at the upper end of a valve stem 30. The latter is controlled'by lever 32 pivotally mounted on a ball seal at '34; Overflow from the bowl runs through opening 36 and thence through passage 38 to the drain pipe. The drain valve 28 is controlled by a vertically reciprocable rod 40, the upper end of which is provided with a suitable head 42 and the lower end of which carries a coupling 44 secured on rod 40 by a set screw or other appropriate means. The rear end 46 of lever 32 passes through coupling 44, thus connecting the same to rod 40 for acuation by raising or lowering the rod. With the rod in its normally lowered position as shown. in Fig. 2, the drain valve 38 is elevated to its open position.

Referring now to Fig. 3 as well as Figs. 1 and 2, in accordance with my invention the valve body 48 of valve 20 and the valve body 50 of valve 22 are cast integrally with one another and with a cross-connection pipe 52 extending all the way from one valve to the other. lPipe 52 is provided with an upstanding boss or T-connection 54. The spout 24 is cast separately, and comprises an enlarged head 56 with a nozzle 58 extending forwardly and downwardly therefrom. The spout is simple in design and construction, it comprising a threaded inlet 60 leading directly to Water passage 62 (Fig. 2).

The head 55 Of the spout is bored in a vertical direction outside the water passage 62 to receive and guide drain control rod 40. Referring to Fig. 2, it will be seen that the boss 54 is provided with a projection 64 which is also bored to receive and guide the drain control rod 40. The passages for the drain control rod are, of course, in superposed alignment.

Except for the fact that the valve bodies are cast integrally with'the cross-connection 52, the valves.20 and 22 may be substantially conventional. Separate valve seats 10 are screwed into the bottoms of the valves, the lower ends of these seats being threaded at 12 to receive appropriate water supply connections leading to the valves.

Valve stems I4 pass through the tops of the valve bodies and are appropriately packed against leakage by means of packing nuts I6. The exterior of the valve body is threaded to receive wing nuts or rings I8 which function to clamp the valve in position above and below the ledge of the basin. The upper nut as well as the packing nut I6 are normally concealed from view by a decorative cover plate or shell 80,'said shell being shown in position on valve 22, but not on valve 20. The shell is secured in place at its upper edge by a nut 82 shown on valve 22, said nut being received on a threaded upward extension 84 of packing nut 'IIS,v this extension 84 being shown at valve 20. Valve stem 14 has mounted thereon an appropriate 'form of handle 86, this handle being omitted from valve 20.

The spout 24 and the boss 54 are connected by a suitable brass nipple: 88,'as is clearly shown in Figs. 2 and 3. The length of the nipple is so selected as to bring the bottom of the spout head 56 approximately in the: same plane as the bottom edges of the cover plates 80. This dimension does not have to be exact, for the cover plates may be located higher or lower to an extent determined by the relation between nut 82 and thread 84. Nipple 88 is shown with right-hand threads at both ends.

' It will be understood. that in practice the entire fixture is mounted on the basin as follows: The upper wing nuts I8 are removed from the valves.- The integrally cast valves and crossconnection 52 are then slid upwardly through the mating openings in the basin, whereupon the upper wing nuts I8 are replaced. Nipple 88 is screwedinto the spout and the lower. end of the nipple is then passed through the center opening of the basin and is secured into boss 54 as by swinging the entire spout around with the nipple. This is done until the connections are tight and the spout points forwardly over the bowl. The spout is made short enough to clear the valves when swung around. Any necessary accommodation to point'the spout in desired direction is readily attained because of the tapered nature of the threads. The nipple may be screwed into the cross-connection 52 before putting the valves in place, and in such case, the only difference is that the spout is screwed onto the top of the nipple. The top wing nuts 18 are then backed away until the head 56 of the spout rests on the basin, at which time wing nuts 18 are turned upwardly to clamp the valves in position. The cover plates 80, nuts. 82 and handles; 86 are then added. Appropriate water supply connections are made to the bottom threads .12 of the valves, and drain control rod is dropped downwardly through the head of the spout. Appropriate connections are then made by means of coupling 44 in order to actuate the drain valve.

the cross-connection 52.

The mode of assembly as so far described presupposes that it is possible to swing the spout around in position. This cannot be done if the basin is provided with a back wall or if the basin has already been permanently mounted in position against the room wall. In such case, it is, of course, possible to use a nipple with right and left-hand threads, and to appropriately change the threads mating with the nipple. Other constructions may be used which do not necessitate the provision of a left-hand thread. .For example, in Figs. 4 and 5, I show a modification in which the spout is secured to the upper end of a special nipple or pipe by means of a slip joint. Referring to those figures, it will be seen that the upright nipple or connection means 90 is threaded at its lower end and screwed into the boss 54 of The upper end is provided with a ground tapered shoulder 92. The head 94 of the spout differs from that previously described, and is machined to mate with the upper end of connection 90. The top of connection 90 is closed at 96 and threaded to receive a screw 98. The spout is slipped over the upper end of connection 90 and is tightened in place by means of screw 98. The side wall of connection 90 is apertured at I for passage of water into the spout. In order to hold the parts in registration, the nipple and the spout are provided with appropriate mating means. In the present case, the connection 90 is provided with keys I02 at its upper end, and these are received in mating slots formed within the spout. In this manner rotative movement of the spout relative to the nippl 90 is prevented. I

Still another and simpler manner for connecting the spout to the remainder of the fixture is illustrated in Fig. 6. In this case the spout 24 is provided with a head 56 just like that first described. The nipple I04 difiers in that the lower thread I06 is carried well up on the nipple. A look nut I08'is received on thread. I and a gasket H0 is disposed between lock nut I08 and the boss 54. The space I I2 within the cast pipe connection 52 is made adequate to receive the lower end of the nipple for a length exceeding the thread length actually received within the spout at the upper end of the nipple.

In practice, the nipple I04 is preliminarily screwed as far as possible down into boss 54. The spout is then heldover the nipple andrthe nipple is screwed upwardly into the spout until a tight connection is obtained. Atthis'time the nipple is, of course, being unscrewed at the bottom, but

ample thread remains in the boss, as is clearly shown in the drawings. The lock nut I08 is then screwed downwardly against gasket I I 0, thus sealing the connection at the bottom of the nipples It is believed that the construction and method of installation, as well as the many advantages of my improved valve and spout assembly, will be apparent from the foregoing detailed description thereof. Inasmuch as the valve casting and spout are made of bronze, while the nipple88 is made of brass, the flow of water is entirely through protected piping. The short connections heretofore used are dispensed with. Four different connections 'or joints are eliminated with consequent source of leaks, and substantial saving of labor for installation and for repair. No lamp wick packing in large quantities or other packing is needed, and there is no danger of obstruction of water flow through the assembly. The drain control rod is connected in a neat and simple manner, and without passage through the water fiow chamber of the spout. The opening in the basin normally provided for the spout is ample in diameter to receive both the nipple and the drain control rod. This is so because heretofore the spout has been made in a more cumbersome manner with an annular passage for water flow, said passage surrounding the guide tube of the drain rod. No such annular passage and complex shaping of the spout are necessary with the present fixture. The guide 64 receiving the drain control rod may, of course, be dispensed with because of the large bearing surface provided by the passage through the spout.

It will be apparent that while I have shown and described my invention in preferred forms, many changes and modifications may be made in the structures disclosed, without departing from the spirit of the invention defined in the following claims.
