EILTERiNG FAUCET] Application filed July 21, 1925. Serial No. 45,104.

This invention relates broadly to valves, partlcularly to faucets, and has for its ob- ]ect the provision of a novel faucet designed particularly for use in connection with the cold water supply of a house or the like, the v 'devlce embodying a filtering mechanism for removing impurities and foreign matter from the water so that it will be fit for use for drinking purposes. 1

Another object of the invention is to provide a faucet provided with means whereby it will be leak-proof without the employ ment of flexible gaskets or the like such as are ordinarily used for the purpose.

Another object of the invention is to provide a faucet embodying not only the above advantageous characteristics but of such construction that the filtering means may be easily removed and replaced by a fresh supply when necessary after prolonged use.

An additional objectis to provide afaucet of this character which will be simple and inexpensive in manufacture, easy to assemble or install, positive in action, efiicient and durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction and. the arrangementand combination of parts to be hereinafter more fully described and claimed, and illustrated in the accompanynig drawings, in which V Figure 1 is a longitudinal section through the complete device.

Figure 2 is a detail section through the cap, and g Figure 3 is a detail section through the retaining member for the filtering material. Referring more particularly to the draw ings, we have shown the device as comprising an upright, elongated hollow body 10 which may be constructed of any suitable size and in any desired shape and from any material preferred. The intermediate portion of this body is formed with a chamber 11 and the lower portion has a bore 12 therein communicating with the chamber through a tapered seat 13. At'itslower end, the

body is exteriorly threaded as indicated at 141 whereby it may be connected with a supply pipe oi the like, and at an intermediate point is provided the usual out-standing flange 15 forming'the proper finish when the device is installed upon a lavatory, sink or the like. The upper end of the body is open bore 12 into'the chamber.

and externally threaded as shown and near .the upper end the. body is somewhat thickened and internally threaded as indicated at 16 for a purpose to be described.

Suitably secured to and projecting laterally from one side of the body and communicating with the chamber 11 therein is 13 for cutting off flow of Water from the portion of this stemisa threaded enlarge- At the upper ment 23 which is screwed into the threaded thickened portion at the upper end of the body, and above this enlargement the stem 21 terminates in a squared or otherwise angularly formed extension 24.

The means for turning the stem 21 to lift the valve head 22 out of engagement with the seat 18, comprises a handle member 25 formed or secured to a shank 26 which-terminates at its lower end in a conical portion 27 cooperating with the seat 19. Below the conical portion 27 is an extension 28 formed with a squared or otherwise angularly formed socket 29 slidably receiving the angular or squared extension 24 of the valve. A coil spring 30 surrounds the extensions 28 and 24 and abuts against the conical mem ber 27' and the enlargement 23 for normally urging the former into close fitting engagement with the seat 19. For preventing longitudinal downward movement of the shank 26 under the influence of pressure applied to the handle 25, we provide a ring or collar 31,

suitably secured to the shank 26 and bearing upon the upper end of the cap.

Located at the intermediate portion of the chamber 11 is a partition member 82 through which the stem 21 is movable, and this partition member is held in place as for instance by means of pins 33 or the like introducedthereinto through the outside of the body.

Formed'or secured upon one side of the body preferably at the side opposite the nose 17 is a casing 34 having a conduit 35 at its lower end communicating with the chamber 11 below the partition 32 through an opening 36. The upper portion of the casing 84: communicates with the chamber 11 above the partition 32 through an opening Located within the casing 34: 1s a reticulated or ioraminated cage member 38 containing filtering material indicated at 39, which filtering material may be granulated charcoal, sand or the like. The top of the casing 34 is normally closed by a removable cap or cover l0 which may be removed when desired to permit extract on of the cage 38 so that the filtering material therein may be changed whenever such is necessary.

In the operation of the device, it will be seen that under normal circumstances, that is when the flow of water is cut off, the -'alve head 22 seats firmly against the seat 1.3. \Vhen it is desired to obtain a supply of water, the operator grasps the handle and turns it in a counter-clockwise direction whereupon the enlargement 33 screws along the threaded portion of the body and the stem '21 rotates and moves upwardly so that the valve head 22 will be withdrawn from engagement with its seat 13. ater may then pass through the bore 12 into the chamber 11 below the partition 32 and will pass out through the opening 36 and conduit '85 into the casing 34 where it of course flows through the filtering material 39 and passes through the opening 37 into the chamber 11 above the partition 32 and thence out through the spout 17. It will be obse ved that the conical member 27 remains always in close engagement with its seat 19 owing to the fact that the squared extension 24 of the valve structure or member may move into the socket 29, there never being any longitudinal movement of the handle member, shank or conical member 27. The above described ring 31 will prevent the conical member 27 from being moved downward-1y out of engagement with its seat even though a heavy handed person apply pressure downwardly upon the handle.

From the foregoing description and a study of the drawing it will be apparent that we have thus provided a simply constructed, inexpensive and very highly efiicient device for the purpose specified. Itis believed that the construction, operation and advantages will be readily apparent to one skilled in the art without further explanation.

Vhile we have shown and described the preferred embodiment of the invention, it should be understood that we reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, we claim:-
