My invention relates to improvements in faucets. 4 Y

In accordance with myinvention, I provide a faucet formed of few and simple parts,

and. which may be conveniently and quickly operated and is reliable in use. The faucet 1s so designed that it has a large water way therethrough so that it will deliver a large quantity of water quickly which is lmpor- 0. tant in drawing water for bath tubs, kitchen sinks, sinks -in industrial plants, etc. The faucet is so constructed that the valve element closes with the pressure of the water, and the valve element and valve seat are ground at an angle of substantially 45 degrees insuring a perfect fit, and eliminating the possibility of leakage, due to the accumulation of deposits, rust, etc. The faucet is adapted to be used on high pressure work. so The faucet is so constructed that the valve element engages a 'stationary non-removable valve seat, and the valve element and valve stem are removable from the bottom of the casing of the faucet, the valve element belng removable from the valve stem and reversible so that its opposite faces may be used. The valve stem has screw-threads of relatively high pitch, so that the valve element may be opened and closed by a turning movement of the handle of the faucet for about a quarter to a half of a revolution.

In the accompanying drawings, forming a part of this specification, and in whichlike numerals are employed to designate like 95 parts throughout the same,

Figure 6 is a central longitudinal section through the same. 1

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral 5 designates the casing of the faucet, which is provided at its forward end with a spout or 5- nozzle 6, and at its rear end witha tubular portion 7, for suitable connection with a pipe. The casing 5 carries an upstanding neck 8. The casing 5 is providedwith a diagonal web 9, forming-inlet and outlet chambers 10 and 11. This web carries an upstanding annular ring or flange 12, integral therewith, as shown. The web 9 has a circular opening 13, leading into the flange 12, and a valve seat 14 is ground upon the web and surrounds the opening 13. The valve seat 14; is annular and is inclined at an angle of 45 degrees from the vertical. The valve seat is, therefore, stationary and is integral with the web.

The numeral 15 designates a valve stem cage, the lower end of which is inserted within the flange 12, and has screw-threaded engagement therewith, as shown at 16. This cage has relatively large openings 17, in its periphery, for the free passage of the water, the cage being tubular with its lower end open, as shown. Formed integral with the upper end of the cage 15 is a sleeve 18, provided at its top with an annular disc or flange 19, having a sliding fit within the upstanding neck 8. This disc has notches 20, formed in its periphery for engagement with a spanner wrench or like implement, to turn the same.

The flange or disc 19 is spaced from the upper end of the neck 8, affording a space for a compressible coil spring 21, engaging a metal washer 22, in turn engaging a flexible or fibrous washer 23, held within a cap 24, having screw-threaded engagement with the upper end of the neck 8. as shown at 25.

The numeral 26 designates a valve stem, extending through an opening 27 in the cap, and having screw-threads-QS formed thereon to engage screw-threads 29 in the sleeve 18. The valve stem embodies a reduced portion 30 extending through the cage 15, and this reduced portion is equipped with a shoulder 31 and an extension beneath the shoulder, these parts being'formed integral. The extension 32 projects below the valve seat 14 and receives thereon an annular valve element 33, engaging a washer 34, held in place by a nut 35 having screw-threaded engagement with the extension 32, as shown at 36. The periphery of the valve element 33 has oppositely arranged beveled faces 37, disposed at an angle of 45 degrees from the vertical. The valve element is readily removable from the extension 32, so that either face 37 may be arranged adjacent to the valve seat 14 for co-action therewith. The casing 5 is provided in its bottom with a main opening 37 in alignment with the valve element 33, so that this valve element may be moved downwardly through this opening, and the opening is covered by a removable plug 38. The valve stem 26 is turned by means of a radial handle 39, detachably secured to the stem 26 by a screw 40, or the like. In assembling the several parts of the faucet, the cap 24 being removed, the cage 15 is inserted downwardly through the neck 8 and its lower end engages within the flange 12 and is screwed up tightly within the same. The plug 38 being removed, the valve stem 26 is inserted upwardly through the opening 37', until its screw-threaded portion engages Within the screw-threaded sleeve 18, the stem 26 being then rotated until the valve element 35 engages the valve seat 14. The lug 38 may then be screwed into the openmg 37 It is obvious that the stem 30 may be readil removed so that the valve element 33 may e reversed thereon, and the parts again assembled. The spring 21 and washer 22 are now inserted into the upper portion of the neck 8 above the flange 19 and the cap 24 placed upon the valve stem 26 and screwed upon the top of the neck 8. The handle 39 is now attached to the top of the stem 26. The screw-threads 28 and 29 have a relatively high pitch, and the valve element 33 may be opened and closed, by turning the handle 39 for a quarter to a half of a revolution. The handle 39 is turned to the left to unseat the valve element, and to the right to seat it.

In Figures 5 and 6, I have shown a modifled form of valve element. This valve element is designated, as a whole, by the numeral 41, and includes an inserted cup-shaped portion 42, secured to an inner tubular portion 43, spaced therefrom to afford a passage 44. The tubular portion 43 is mounted upon the stem 30, beneath the flange 37, and is held in place by the nut 35. The cup-shaped portion 42 engages the valve seat 14, and the water under pressure enters the cup-shaped ortion 42, expanding the same and forcing it against the valve seat 14.

It is to be understood that the forms of my invention, herewith shown and described, are to be taken as preferred examples of the same, and that various changes in the sh p size and arrangement of parts ma be resorted to, without departing from t e spirit of m invention, or the scope of the subjoine claims.

Having thus described my invention, I claim:
