IMPROVEMENT IN BASIN-FAUCET.

Specification forming part of Letters Patent No. 163,005, dated May l1, 1875; application led February 11,1875.

To all whom it may concern:

Be it known that I, JOHN FARRHLL, of Pittsburg, county of Allegheny, State of Pennsylvania, have invented or discovered a new and useful Improvement in Valve-Cocks; and I do hereby declare the following to be a full, clear, concise, and eXact description thereof, reference being had to the accompanying drawing, making a part of this specification, in which like letters indicate like parts.

Figure lis a section taken on a vertical plane through the center of a valve-cock constructed in accordance with my invention; and Figs. 2 to 8, inclusive, are detached views of various parts thereof.

My invention relates to the construction and combination of certain parts of a valvecock, in which the valve is raised from its seat by means of double-reverse inclines, and closed by the expansive power of a spring, as `hereinafter set forth and claimed.

The casing A of the valve-chamber is constructed with the induction and eduction pipes Al A2 and a valve-seat, whereon the requisite valve for opening and closing com* munication between the valve-chamber and eduction-pipe is seated. In this connection AI prefer to construct the valve-stem c with a collar, c1, and swivell the valve d thereto, so that rotation of the valve-stem may not necessarily impart to the valve and packing a like movement, and consequent wear while in con- 'lo seat this valve, as against water-pressure, I arrange around its stem a coiled spring, e, and adjust its elasticity with reference to such pressureV by an adjustable screw-ring, f, working within the cylindrical screw-threaded case B. In order to effect a vertical movement of the valve and stem by a partial rotation of the handle g either to the right or to the left, I make a tubular piece, a, Figs. et and 5, with doublereverse inclines al, sometimes designated as i cam-surfaces, and fixedly set andy hold the same in a preferably squareshaped seat at the end of case B by means of a screw-cap,

B. Io the handle g, which is connected with the stem c, as by a screw and washer, I attach a counter-piece, b, having double-reverse inclines b1, corresponding to the inclines of piece a, and t the-same down upon the inclines of the piece c, whereby a rotation of the handle and its piece b will produce a rectilinear or vertical movement of the valvestem and valve, and open the port for the inflow of water from the induction-pipe into the valve-chamber. After the handle has been released the valve Will be resealed by the springpressure before described. In order that the greatest possible vertical movement ofthe stem shall be less than the height of the inclines, so that the points of juncture b2 of the inclines on piece b may not center and rest upon the corresponding points a2 of piece a, I locate a stop, L, preferably in the upper end of case B, and form a shoulder, c2, on the stem c, which, when striking against the said stop, will limit the upward movement of the stem and handle connected therewith. The base-plate c3 of piece a is made of square or other than circular form, so that the position of the handle with reference to the deliveryspout when the valve is closed shall be fixed by the adjustment of the piece c in the case b, and also so that, by changing the position of the base-plate, as by turning it one-quarter of the way aroundl in its correspondingly-shaped seat, the handle may, at pleasure, be brought into line with or stand at right angles to the delivery-spout when the valve is closed'.

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

l. The combination of' a valve closing against the pressure, a screw-ring adjustable in the case or chamber independently of the valve-stem which passes through it, and a springinterposed between the screw-ring and valve, substantially as and for the purposes set forth.

2. The piece a, having double inclines in opposite directions, made independent of the cap in which it is seated, in combination with the counter-piece b, made independent of the stem which passes through it, but rigidly connected with the handle, the parts being Y arranged and combined substantially as Yset forth.

In testimony whereof I have hereunto set my hand.

' JOHN FAHHELL.
