IMPROVEMENT lhl FAUCETS.

Specification forming part of Letters Patent No. ML'EB, dated November 8, 1864.

To @ZZ whom it may concern.'

Be it known that I, JOI-IN BROUGHTON, of the city, county, and State of New York, have invented a new and useful Improvement in Faucets; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying` drawings, forming part of this specification, in which- Figure l is al side view, and Fig. 2 is aview of a vertical longitudinal section, of a faucet made after my improvements. Fig. 3 is a plan of the valve.

Similar letters of reference indicate corresponding parts.

This invention relates to certain improvements in the construction of cocks or faucets, whereby the principles and features of a compression-valve and the opening and closing m0- tions of the ordinary plug-valve are combined, and an article produced which is simple in construction, durable in wear, and which can be operated more easily than any other.

A is the shank or supply chamber of the cock,which is secured to the discharge-ch amber B by a screw-joint, which unites the lower end or base, li, of the dischargechamber with the upper end, a, ofthe supply-chamber, the end c being screwed over the base It until it abuts against its shoulder s. The diameters of these chambers are enlarged at their parts a and it so as receive the valve F. The discharge-chamber l5 is provided with an eduction-nozzle, C, and its neck is perforated to admit the insertion of the valve-spindle H. The neck is elongated within the dischargechamber by the projecting collar or thimble i, which serves as a tubular bearing for the The neck of the chamber is enlarged at its top to receive suitable packing, l, which is held in place by au angular washer, mi, which in turn is held in place by a common bibbspring, O, upon which the ball of the handle J ofthe spindle rests. The spindle is squared at its outer end, and lits into a square recess cut nearly throughv the handle J, vertically.

The square partot' the spindle is recessed io,

receive a screw, K, which passesthrough the top of the handle J into the sd Iare recess within. The valve-spindle extends down within the chamber B, and below its base into the shank A, to the line where it first reaches its greatest diameter, where it is secured to the disk-valve F, whose diameter is nearly equal to the diameter of the interior of the shank A. A shoulder, j", is formed in the end d of the shank, whose face must be in the same vplane with the inner face of the valve F, so that an annular washer, n, of cork or other suitable material, may lie upon the said shoulder and be held against it by the lower end of the base h of chamber B, where said base is properly screwed into the shank A. When the valve is properly adjusted for use, it should rotate in contact with the face of the washer. An annular plate, c, is tted around the valve-spindle H, its circumference being secured under a shoulder, 3, cut in the inner wall of the base It of the discharge-chamber, or this plate may be cast with the base.

g g are openings or water-ways in the diskvalve F, and like openings, to coincide with them when the valve is open, are made through the washer n and plate c, and around the edges ol' these openings in the plate are teeth, 2 2, which project downward and indent themselves in the washer to hold it in position.

Fig. 2 represents the valve as open.

When the handle J is turned at right angles to the position shown, the openings in the washer-plate are closed, and the pressure of the iuid acts against the back of the valve and compresses its elastic seat, thus tightening the joint, the valve bein g perfectly free to move forward in the direction of the pressure. Whatever the extent i f its longitudinal movement may be, the lioint 0f the spindle at l m will not leak, owing to the presence of the packing l, through which the spindle moves.

The valve F may be adjusted to compress the elastic seat by turning the screw K in the handle J until thejoints of the spring 0 close up and it assumes the shape ot' an annular ring, the ball of the handle J being in contact with it, and remaining stationary while the valve-spindle and valve are drawn forward by the action of the screw. This insures a certain contact between the valve and its elasticseat, independent of the pressure of the iiuid within the shank A of the faucet, and prevents any rebound of the valve beyond that point, while vibrating on its elastic seat, under the eliect of suddenly stopping the flow of the seat n, spindle H, and handle, substantially as described.

2. The employment ofthe spring 0, to keep the valve in contact with its elastic seat, independent of the pressure of the fluid, when arranged in conjunction with the spindle H,

the discharge-chamber B,and the handle J,

substantially as described.
