FRANCIS 'ETOTTEN, OF NEIVARK, NEIV JERSEY, ASSIGNOR OF ONE-HALF TO JOSEPH STOII E COOKE, OF SAME PLACE.

FAUCET.

SPECIFICATION forming part of Letters Patent No. 407,381, dated July 23, 1889. Application filed April 24, 1888. Serial No. 271,689. (ModeL) To all whom it may concern.-

Be it known that I, FRANCIS EDWIN TOTTEN, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Faucets, of which the following is a specification.

My invention relates more particularly to self-closing faucets, which have heretofore been made in a variety of ways.

The main objects of my invention are to provide a faucet with cheap, simple, durable, and efficient valve-operating means; and to these ends it consists in the features of construction and combinations of parts hereinafter more fully described and particularly pointed out in the appended claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a faucet embodying my invention. Fig. 2 is a central vertical sect-ion of the same, the valve-actuating devices being shown in elevation. Fig. 3 is a rear view of the faucet. Fig. 4 is a top view of the same. Fig. 5 is an elevation of the retaining-screw. Fig. 6 is a bottom view of the handle. Fig. 7 is an elevation of the valve and its stem. Fig. 8 is an elevation of the lifting-pins, and Fig. 9 is a plan view of the cap or top of the faucetbody enlarged.

In the various views the same parts willbe found designated by the same letters and numerals of reference.

A is the body or shell of the faucet; B, its shank, screw-threaded for connection to a supply-pipe, and 0 its nozzle or discharge portion. The water-way through these parts is designated by the letter a.

D is the valve-stem, preferably cast with acollar or flange b at its lower end and made square or angular at its upper end 0. To the flange or collar 1) may be secured a rubber valve d, adapted to the seat 6 in the body or shell of the faucet.

E is a screw-cap having a central perforation f, through which the valve-stem is adapted to work. The underside of the screw-cap is provided with a chamber to receive a packing-ring g.

H is a spiral spring resting at one end against the flange b of thevalve-stem and at its other end against a ring h, formed inte-' gral with a sleeve 2' and surrounding the valvestem just below the screw-cap.

Then the cap is screwed onto the upper threaded end of the shell, the spring is compressed and the valve forced tightly against its seat to prevent the escape of any water. On the upper side of the cap are formed or provided two diametrically-opposite oblique depressions, cavities, or seats 2 2, in which are fitted or inserted the lower ends of obliquely-arranged pins or rods 3 3, whose upper ends are fitted or inserted into obliquelyformed depressions or bearings 4 Al in the under side of a handle or cross-piece 5, which is provided with a square or angular hole 6 about centrally of its length for engagement with the upper end of the valve-stem. A screw 7, passing through the hole 6, engages with a threaded hole in the valve-stein and secures the handle and the pins or rods 3 3 in position.

The handle extends, preferably, at right angles to the nozzle, and the depressions 2 2 are formed in line with' said nozzle and on opposite sides of the perforation f. The bars or pins 3 3 incline outwardly and upwardly in opposite directions from said depressions to the seats 4 4, near the extremities of the handle.

In assemblin the parts together the spring, the sleeve, the packing, and the cap are slipped onto the valve-stem from its upper end and the cap screwed onto the shell or casing, as shown at Fig. 2. The pins are then inserted at their lower ends in the depressions in the cap, and while held the cross-piece or handle is fitted over their upper ends and onto the projecting end of the valve-stem. The screw 0 7 is then inserted and the parts confined in working posit-ion.

2, (the centers of movement of. the pins,) and the pins are straightened up some orbrought to nearer a vertical position, the effect being to raise the handle as it turns and lift the valve-stem and valve against the action of the spiral spring. The dotted lines in Figs. 1, 3, and 4: show the relationship of theparts when the valve is raised. Upon releasing the handle the spring returns all the parts to their firstpositions. The upper ends of the inclined pins being forced to travel in an arc of a circle whose center is the vertical axis of the handle while t-helower ends of the pins are stepped or journaled or pivoted eecentrically to the handle, it will be understood that the force applied to turn the handle will elevate the outer ends of the pins, and they will in turn effect a raising of the handle and the valvestem and valve connected thereto.

The spring 4 is so arranged that upon a lifting of the valve its coils close together and form an abutment to limit the upward movement of the valve and valve-stem, the rotation of the handle, and the raising and straightening up of the pins, and the relative arrangement of the parts is such that the spring opcrates as an abutment or stop before the handle can be so far turned as to bring the pins into line with the center of the faucet or to the dead-point, and hence there is no liability of the valve getting locked open. By

reason of the presence of the spring the handle is prevented from being turned to such an extent as would permit the pins to be Withdrawn from the depressions 2 2 and 4 4, and hence no additional means are required for maintaining the pins in position at all times.

What I claim as new, and desire to secure by Letters Patent, is

In a faucet, the combination. of a shell provided with a valve-seat, avalve, a valve-stem, a shell-cap provided With a perforation j" and adjacent depressions 2 2, a spring encircling the valve-stein within the shell, a handle provided with depressions 4: 4 on its under side, and inclined pins fitted into the depressions 2 2 at their lower ends and into the depressions 4: 4: at their upper ends, the arrangement being such that the spring operates not only to force the valve down upon its seat and return all the moving parts to their normal positions, but to also hold the lifting-pins in place, as Well as prevent their being raised and turned to the dead-point and thus looking open the valve.

Signed at New York city, in the county of New York and State of New York, this 21 st day of April, A. D. 1888.
