SELF-ACTING FAUCET.

. SPECIFICATION forming part of Letters Patent No. 289,710, dated December 4;, 1883.

' Application filed April 2, 1883. (N0 model.)

T0 on whom it may concern:

Be it known that we, ANTON PRIER, CHARLES DOHERTY, and PIERcE E. EVERETT, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Improvement in Self-Acting Faucets; and we do hereby declare that the following is a full, clear, and exactdescription of the same. r

This invention pertains to improvements upon our faucet, an application for Letters Patent for which was filed December 12, 1882, and allowed March 2, 1883, the same having for its object facility of operation, and to steady the valve-stem to obviate the rattling of the valve or its stem; and the invention consists of means for carrying out the aforesaid obj ects, substantially as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a vertical section of our improved faucet. Fig. 2 is a perspective view of the valve and stem; and Fig. 8 is a detailed side view of the camcap, lever, and valvestem, the cap being broken away. a

To carry out our invention, we employ. a screw-threaded pipe, A, with the external outlet pipe or spout, A, and the internal valveseat, a, and flange or shoulder a, arranged above the valve-seat, and the elastic thimbleshaped cushion or spring B, resting upon the flange or shoulder a, and having an aperture for the passage of the valve-stem through it. The outlet pipe or spout A has an outwardly and downwardly inclined surface around the valve-seat, to prevent the water standing around that point, and thus obviate the formation of ice thereat in freezing weather.

The construction thus far described is substantially the same as that shown and described in our above-referred-to application.

above the valve with concavities or waterways a 0, whereby as the valve is opened the water is allowed to enter said cavities or ways and pass from the same into the discharge-chamber or outlet-pipe A, while by the stem being constantly in contact with the valve-seat the 5 stem will be prevented from hammering the seat, thereby avoiding the rattling noise occurring thereat.

To aid the prevention of the hammering of the valve-seat by the valvestem, the concavities c of the valve-stem are tapered along their bottoms and sides to their extremities, which has the effect to readily deflect the passing water and to evenly distribute its pressure when the valve is open.

The elastic cushion or spring B has fitted around it a metallic band or cylinder, d, the same as in our former application, which cylinder holds it upon theflange a, while the cylinder is held in place by means of the cam-cap D, screwed upon the pipe A. The valve-stem is provided, just above where it passes through the spring B, with a screw-thread, to secure in position thereon a nut, e, and a smaller nut, e, the nut e resting upon a washer, 6 also inserted upon said valve-stem, which hold the spring or cushion upon the valve-stem, the under side of the cushion or spring resting upon a washer, f, supported upon a shoulder, f, of the stem, as in former application.

E is the lever, which is preferably made after the fashion of a thumb-nut minus the screw-thread, said lever being fitted to turn upon the valve-stem O and resting upon the nut 6, its arms extending through lateral openings in the cap D. The upper side of the lever E is provided, around a collar, 9, thereon, with inclined cams g 9, two of which are arranged on opposite sides of the collar, the base of each cam on one side of the collar meeting the base of each of the cams on the opposite side of the collar. The cap D has a similar arrangement of cams, h h, around an opening therein, whichare the counterparts of the cams g of the lever E, and coact with those of the lever as the latter is turned by the hand to effect the depressing of the valve to overcome the upward pressure of the spring B in opening the valve. The closing of the valve is effected automatically by the action of the I00 spring. The sides of the cap D are cut away or shaped coincidently with the shape of its cams, to allow the lever to have the necessary movement for operating the valve.

The foregoing construction and arrangement of the cap and lever enable the opening of the valve with facility, and the application of but little pressure.

Having thus fully described our invention, we claim and desire to secure by Letters Patent- In a faucet, the combination, with the stationary cap having the double-inclined oppositely-disposed cams arranged on the under side of the cap, of the lever having cams
