VALVE FOB- WATER DISTRIBU'I'IbN.

Specification of mm. Patent.

Patented Mar. 26, 1912.

Application filed June 14, 1911. Serial No. 688,148.

To all whom it may concern Be it known that I, THOMAS GRA NT Cooxn, a citizen of the United States, reslding at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Valves for Water Distribution, of which the following is a specification.

This invention relates to improvements in valves for water distribution and more particularly to compound faucets.

It is the object of this invention to construct a compound faucet, commonly termed a combination bib, where cold water, hot water, or any desired mixture of the two flows from a single discharge with the parts so arranged that a single valve controls both the cold and hot water, and a'mixture of the two of a desired temperature may be accurately produced.

I It is a further object of this invention to construct a combination bib in which leakage is prevented without the use of packing nuts, stuffing-boxes, packing or stuilin of any kind and in which all thewear o the vmovable parts that would tend to produce leakage is automatically takenu While thepreferred forin of t invention is illustrated on the accompanying sheet of drawing yet it is to be un erstoo that minor detail changes may be made without departing from the scope thereof.

Figure 1 is a view in front elevation with partsin section illustrating this invention. Fig. 2 is a view in full side elevation. Fig. 3 is a view in horizontal section of the rotatable valve member taken on the line 1 -2 on Fig. 1. 4

The pipes 1 and 2 leading from the hot and cold water mains are brought together in front and enter on diametrically o posite sides'of, a valve chamber 3 in the orm of a truncated cone. corresponding shape but of lesser depth is mounted. to rotate in the chamber 3. Throu h a central openingin the top B of thevaIve chamber 3 a valve stem D passes and is secured to the top A of the conical valve 4. A sleeve 5 integral with the valve chamber 3 extends upward from the top surroundin the valve stem D, and of sufiicient inside diameter to allow for a coil spring F about the valve stem D. The spring rests upon the top B of the valve chamber 3 and is held under compression by a washer 6 at the top surrounding the valve stem D A hollow'valve 4 of and secured thereto by a pin 7. A cap E is placed about the valve stem and secured to the top of the sleeve for protecting the spring and keeping foreign matter from entering the sleeve. The usual hand wheel Y O is secured to the outer extremity of the valve stem.

As above stated the valve 4 is hollow and in the form of a truncated cone. The water from the hot and cold mains enters through ports 8 in the side of the valve. A central discharge port 9 is formed in the bottom of the valve which is provided with a depending flange or sleeve 10 screw threaded at the bottom to receive a securin nut H for a rotatable discharge nipple The pipes 1 and 2 leadin to the hot and cold water mains are provided with flan es G and the extremities are screw threa ed and provided with locking nuts K for securing the fixture in place. I

As shown in Fi 3 the conical valve 4 is provided with a p urality of ports 8 which are so arranged. that when the valve 4 is in the position shown in Fi 1 and 3 none of the ports register with either pipe. The ports are so disposed and are in such relation to each other that by continued rotation of the valve 4 the full discharge from one main, three quarters of that main and one quarter of the other, a full discharge from both at once, a quarter of the first and a full discharge of the second, a full discharge of the first and a half discharge of the second will be respectively delivered. The conical valve bein retained against the conical valve cham er by the sprlng u on the outer side at the top of the chem er it is not.

necessary to use packing of any kind to prevent leakage. The constant rotation of the valve will wear the parts eventually and; the spring constantly drawing the valve upward will compensate for such wear. By the arrangement of the ports any desired temperature in the discharge may be preduced' by turning thevalve to the proper position. v

What I claim is:

In a combination bib or faucet, a conicalvalve chamber with sides sloping upward having an open bottom and closed to pi es leading trom opposite sides of the 0 am r to the mains, a hollow rotatable valve com prising corres ondingly shaped walls, a closed top, a c osed bottom rovided with a small central discharge ori cc, and a plurality of ports of varying sizes provided in thereon, a cap surrounding the valve stem 10 the valve walls adapted to register with the and forming a closure for the sleeve, the pipes, a valve stem secured to the topof the discharge orifice of the valve provided with valve passing through an orifice in the :top a depending flange forming a' securing of the chamber, an Integral sleeve upon the means for a discharge nipple. v
