COCK OR FAUCET.

SPECIFICATION forming part of Letters Patent No. 508,211, dated November 7, 1893. Application Bled September 13l 1892. Serial No. 445,737. (No model.)

To all whom it' may concern:

Beit known that I, GEORGE T. EYANsoN, a citizen of the United States,and a resident of Philadelphia, in the couuty of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cocks or Faucets, of which the followingisa speciliation.

My invention relates to that class of cocks and faucets in which a pair of hand-levers is employed to elevate a spring-actuated valve, as shown for instance in the patent toP. W.

-Doherty, No. 161,768, dated April 6, 1875, and

my invention has for its objectsto improve the construction of such cocks and faucets and provide a contrivance in which the hand-por.- tions of the levers are so formed or shaped as .to preclude or render most difficult the operation of fastening them together for the purpose of mechanically holding up or vopen the valve and permitting a constant or unduly long dow of water without keeping the hand upon and squeezing togetherthe handle-portions of said levers. Heretofore the construction has always been such that a key-ring or analogous device could be slipped over the handles when drawn toward each other to raise the valve, and made to serve as a tie or clasp to look the valve permanently open or elevated, which is of course highly objectionable in this class of contrivances.-

My invention consists in the features of construction and combinations ot' devices hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanyingdrawings, Figure 1, is

a side View, partly in section, of a cock or faucet embodying my invention. Fig. 2 is a horizontal section taken at the line 0c, of Fig. 1. Fig. 3 is a partial vertical section taken at the line y, y of Fig. 2, and Fig. 4 is a partial side elevation to illustrate the previous Y form or construction of handle-ends, and the application thereto of a ring or clasp for holding them together.

In the several views ofthe same part will be found designated by the same numeral of reference.

1' is the body of the faucet, 2 the spout, 3

5c the valve-seat, 4 the valve, 5 the valve-stem,

into which is fitteda ring 14,havinga central perforation for the passage of the valve-stem and provided on yits upper side with two diametric'ally-opposed tracks, or fulcra 15, preferably cast integral with `the ring. On the under side of the ring is provided apin orlug 16, which enters a hole or depression 17 formed in thecap, by which means the ring is preventedfrom accidentally turning relatively to the cap. There may be two such holes or depressions 17 to secure the ring in either of two positions according to the direction it is desired to have the tracks or fulcra and the hand-levers stand with respect to the spout or vdischarge portion of the cock or faucet.

19 and 2O designate the crossed hand-levers, which are made slightly different, but each consists essentially of a handle-portion 2l, and a bearing portion 22. The lever 19 is formed with two side plates 23, and an end piece 24, connecting them together, and forming on its under side the bearer 22. In the space formed between the two side plates `is fitted the lower end 25 of the hand-lever 20, which adjacent to the bearer 22 is slotted or cut-away as at 26, for the reception of the upper end of the valve-stem. The side plates 23, and the end portion 25 are perforated in linc with a hole in the upperend of the valvestem, and a pivot-pin or small bolt 27 is passed through these several perforations and is held in place by a nut 28. When the parts have been thus secured together the bearing portions 22 rest upon the tracks or fulcra 15.

The handle portions 21 are of peculiar form or construction, in that about or slightly above the pivot 27 they extend first upwardlyl from each other, and then upwardly toward each other. In other words, the lower por- TOO s seam 1 tiens of the handles diverge, and the upper portions converge. In the normal position, the upper extremities of the converging portions stand an inch, more or less, apart, in order to permit the raising of the valve, which is accomplished .by the squeezing together of the handles. By giving the handles both an outward and inward bend, they can never be brought into parallelism as heretofore, and when squeezed to lift the valve, as shown by the dotted lines at Fig. 1, the slant or Obliquity of the outer surfaces of the handles is such that a key-ring or other ordinary device cannot be slipped over and made to lock the handles in their closed positions. Nor will the slanting sides permit the tying of the handles by a string or cord, which will slip under the stress ot the valve-spring. The outward and inward bends of the handles may be made on either curved or straight lines, or both. I prefer to curve the handles, as shown at Fig. l, as a more graceful construction is thereby produced. But the bends may be made on straight lines, as indicated by the lines a at Fig. 3.

Besides the advantage of preventing the locking open of the valve, the shape or con-V struction of the handles affords a much bet ter and surer grip for the hand of the user in the act of raising the valve. In the old construction the handles cannot be brought close together and the valve entirely raised by the full hand, but only by the free end ot .the thumb and one or two opposing linger tips. With my improved construction the levers may be grasped firmly and squeezed by the whole hand, thus securing the advantage of additional sets of muscles, particularly the powerful ones at the bases of the ngers and thumb. Thus the valve may be raised with less effort and more conveniently than here.-A tofore.

From what has already been said, the oper ation will readily be understood, and it seems only necessary testate that when the handles its spring and raise the valve from its seat. 5o

Upon releasing" the grip on the handles the spring of course -returns all of the movlng parts to their irst positions.

What I claim as new, and desire to secure by Letters Patent, is Y l. In a self-closing faucet, a pair of valvelifting levers, the handle-portions of which are formed first to diverge from and then to converge toward each other, substantlallyas set forth.

2. In a self-closing faucet, a pair of valvelifting levers, the handle-.portions of which first diverge from and then converge toward each other on curved lines, substantially as set forth.

3. Inafaucet,thecombination withthebody, of a valve, a spring-actuated valve stem, a cap having 'ulcra, anda pair of crossed levers pivoted together and to the valvestem, and having each a bowed or crooked handle-portion, substantially-as set forth.

4. In a faucet, the combination with the body, of a valve, a spr-ingactuated valve-stem, a cap having a depression, a ring having ful ora seated in said depression, means for preventing said ring from accidentally turning, and a pair of crossedlevers pivoted together and to said valve-stem, and having each a handle-portion diverging first outwardly and upwardly and then converging inwardly and upwardly, substantially as set forth.
