SELF-CLOSING FAUCET.

.SIPEGIFIGATION forming part of Letters Patent No. 249,579, dated November 15, 1881.

Application filed May 25, 1881. (No model.)

To all whom it may concern Be it known thatwe, JAMES E. BOYLE and HENRY ,HUTBER, both citizens of the United States, residing, respectively, in Brooklyn, Kings county, New York, and in New York city, New York, have invented certain Imon its seat normally by a spring, and is lifted provements in Self-Closing (looks or Faucets,

of which the following is a specification.

This invention relates to that class of cocks orfaucets in which the valve is held down upfrom its seat by means of a lever connected with thestem of the valve.

The purpose of our invention is not to effect any change in the operation of the cock, but in its construction, whereby its parts may be put together and taken apart with greater l'acility.

In the ordinary construction of these cooks the cheeks of the operating-lever embrace the projecting end of the valve-stein, and are connected with the stern by means of a pin which passes through all and screws into one of the checks of thelever. To cause the spring around the valve-stem todraw the checks of the operating-lever down snugly and elastically upon the cap of the valve-chamber, (whereby looseness and rattling is prevented,) and at the same time permit the spring to seat the valve properly, it is necessary that the aperture in the stem through which the pin passes shall be drilled with absolute accuracy. To this end the valve is seated, and the cap through which the stem passes is screwed down firmly to its seat. 'The cheeks of the operating-lever, al-

ready drilled to receive the pin, are now set to ofinsuringthefirm settingofthelever on the cap of the cock. If the drilling of the stem be not accurately done, either the valve will be lifted fromits seat by forcing in the pin, or the checks of the lever will not rest firmly upon the cap.

. Moreover, if the holes in the checks of the lever do not coincide with that in'the stem, it is accuracy is required, is necessarily excessive.

To obviate the abovenamed diflficulties and render the parts of the cock not only easyto put together, but interchangeable, is the object of our present invention, which we will now describe with reference to the accompanying drawings, in which- Figure l is a vertical midsectiou through the operative parts of a cock constructed accordingto our invention. Fig. 2 is a crosssection of the. same, taken in the plane of the line 2 2 in Fig. 1. Fig. 3 is afragmentary section taken in the plane of the line 3 3 in Fig. 2. Fig. 4 comprises views of different forms ofthe cross-pin removed. all

Let A represent the ordinary valvechamber, B the valve, (3 the valve-stem, I) thespring, and E the cap, of an ordinary self-closing cock. These are all constructed and arranged in the usual way.

To lift the valve from its seat against the elastic resistance of the spring, a lever, F, is employed, the cheeks a a of which rest on the cap E, which serves as a fulcrum, thelever being connected with the stem by means of a pin, b, which passes through the checks at a and the valve-stem. The arrangement and operation of these several parts are, broadly speaking, old but the construction which we will now describe is new, so far as we are aware.

The aperture cin the stem (3, through which the pin b passes, is elongated in the nature of a slot, and anaxial screw, d,is provided, which screws down into said slot through the end of the valve-stem. The pin 1) is, by preference, slightly reduced in diameter where the said screw impinges upon it, so that it cannot play longitudinally. It may be turned to a smaller tened on one or both sides, as shown in Fig. 4. The handle 6 of the lever F isdetachable, and screws into the bridge or tie f, which con meets the cheeks a a.

In putting the parts of the co'cktogether the valve and spring are properly placed and the cap E screwed firmly down to its seat-t diameterat its middle, or it may there be fiat- The cheeks of the lever F are now caused to embrace the protruding end of the valve-stem and the pin 1) passed through. This is rendered easy by the elongation of the aperture 0. The handle '6 is now unscrewed, and the screw d inserted and run down upon the pin by inserting a screw-driver at the hole in the tief, from which the handle has been removed. The screw is run down only far enough to seat the cheeks a a firmly on the cap E, and not far enough to lift the valve from its seat; and after this adjustment is properly effected the handle 6 is screwed firmly in, and the cock is ready for use. The parts made in this manner are interchangeable, and may be put together and adjusted with ease, accuracy, and rapidity and with very little expenditure of skill orjudgment.

We have shown our invention as applied to a cock having a vertically-arranged operatinglever; but it may as well be employed in cocks having horizontally-arranged levers.

Having thus described our invention, we claim- I. Aself-closing cook or faucet in which the pin connecting the operating-lever with the valve-stem passes through a longitudinallyelongated aperturein the stem,.and a screw is arranged axially in the stem and adapted to bear upon the said connecting-pin, whereby the proper adjustment and seati-ng of the operating-lever is effected, substantially as set forth.

2. A self-closing cock or faucet comprising a valve-chamber and cap, a valve and its stem, and a spring to hold the valve down to its seat,

all arranged in the usual way, an operatinglever with two cheeks to embrace the valvestem, a pin to pass through the two checks of the lever, andan elongated aperture in the stem, and anaxial screw in the end of the stem, arranged to enter the aperture in the stem and bear upon the connecting-pin, substantially as and for the purposes set forth.

3. The combination, with thevalve-chamber, its cap, the valve, and the spring, of the valvestem with an elongated aperture to receive the connecting-pin, and an axial screw to enter said aperture and bear upon said pin, the said connecting-pin and the operating-lever provided with a removable handle, whereby the axial screwin the valve-stem may be reached, substantially as set forth.

4. The combination, with the valve-chamber, the valve, its spring, and the valve-stem provided near its upper end with an elongated slot, and having a screw entering said slot from its upper end, the rocker-lever, and a pin adapted to pass through the cheeks of said lever and the said elongated slot, and reduced in diameter opposite the end of the said screw, whereby the end of the screw enters between two shoulders thereon, and the longitudinal displacement of the pin is prevented, substantially as set forth.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
