RICHARD MURPHY, OF CINCINNATI, OIllO, ASSIGNOR TO THE THOMAS GIBSON COMPANY, OF SAME PLACE.

BALL-COCK.

SPECIFICATION forming part of Letters Patent No. 425,619, dated April 1 5, 1890.

Application filed December 6, 1889. Serial No. 332,793. (No model.)

To aZZ whom it may concern:

Be it known that I, RICHARD MURPHY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Ball-Cocks; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form part of this specification.v

This invention relates to those cocks which are automatically opened and closed by a ball that floats on the surface of the water in the tank or reservoir to which such cocks are ap' plied; and the first part of my improvements comprises a novel combination of casin g, moving water-Way, valve-seat, and ports, which enable these automatic actions to be effected with theleast possible friction, as hereinafter more fully described.

The second part of my improvements consists in providing the cock with numerous small passages that divide the water into a series of fine jets before it escapes at the discharge-nozzle, whereby the disagreeable hissing or singing noise incidental to the closure of ordinary ball-cocks is obviated. These passages are preferably made in a plate that constitutes the valve-seat of the cock, as hereinafter more fully described.

The third part of my improvements consists in forming a counterbore in the upper surface of the seat-disk and'arranging the moving water-way to close within said counterbore, by which arrangement a water-trap is formed, which trap prevents any hissing at the very instant the closure is effected, as hereinafter described.

In the annexed drawings, Figure l is a side elevation of a ball-cock embodying my improvements, the moving water-way being closed. Fig. 2 is an enlarged axial section of the cock proper, the moving water-way being closed and shown in elevation. Fig. 3 is a similar view of a slightlyqnodified form of the cook, but showing the water-way open and sectioned. Fi 4; is an enlarged plan of the valve-seat detached from the casing. Figs. 5, 6, and 7 show three different modifications of the valve-seat.

A represents the barrel or shell or easing of the cock, which barrel is bored out at 13 to permit free play of a pair of cupped leather packings C C, secured to the moving water-way D, the latter being provided with a longitudinal channel E, open at bottom but closed at top and having one or more lateral ports 0. Furthermore, the upper end of this water-way is slotted at (Z to admit a rounded bearingj' of a lever F, pivoted to a fulcrum-bearing G, which latter projects from the casing.

II is an ordinary float or ball at the free end of said lover. The lower end of easing A is screw-threaded externally, as at a, to permit the engagement of a cap I, having a discharge nozzle or pipe i.

J is a disk fitted in the lower end of easing A, and having its upper surface counterbored at K and provided with a leather or other suitable seat L.

j are small holes made in this disk between. its margin and the eountcrbore K, which disk may be secured in place by any suitable means; but I prefer the screw-connection shown, inasmuch as it permits the disk to be adjusted either up or down, as occasion requires.

M is the inlet-pipe of the barrel or casing.

The various parts of this cock are so fitted together as to cause the lower end of wa terway D to bear snugly against the seat L when the tank or reservoir is filled to the de sired level, which closed condition of the cock is seen in Fig. 2, the barrel and water-way being now 'lilled, but no escape taking place at the ventage 2'. As soon, however, as the water in the tank begins to fall, the moving water-way D is raised, which act opens the cock to its full extent. The water then flows through the ports 6 into channels E and out of the open end of the latter into the space at the lower end of the casing, from whence it is discharged through the numerous openings j and finally escapes at the nozzle 13y thus compelling the water to escape in nu merous fine jets the disagreeable hissing or singing noise incidental to the-ordinary form of ball eock is obviated, which noiseless action of the device is rendered more effective by causing the descending water-way D to enter the counterbore K before coming to a positive stop, thereby forming a trap at the bottom of the apparatus. The water-way moves very readily both in opening and ,closing, because it is almost entirely surrounded by the fluid, and the cupped packings C C render said waterway as nearly balanced as it is possible to make it. Consequently the waterway moves with very little friction, and being unprovided with a stuffing-box there is no danger of it getting out of order.

In the construction shown in Figs. 1 and 2 the lever F is of the first class, but in Fig. it is of the second class, whichlattcr arrangement is used with those cocks which open and emptya cistern at regularintervals, this peri odical opening being controlled by a bypass valve of any approved form.

The device for muii'ling or deadening the noise of the escaping water may be modified, as seen in Fig. 5, where the valve-disk is pro vided with a series of notches or slots N, which perform the duty of the holesj, previ ously described; butin Fig. (3 the cap I .has a short perforated neck 0, closed at top, and having the valve-seat L secured thereto.

I11 Fig. '7 the cap has an integral disk I,

I supported upon feet p, and having the valveseat L screwed thereto, which seat serves to hold a piece of wire-cloth R in place, the meshes of the latter acting in the same manner as the perforated disk J I claim as my invention-- The combination, in a ball-cock, of. a

moving water-way operated by a float, a seat against which said water-way closes, and a series of small discharge-passages between said seat and the common outlet of the cock, whereby the retraction. of said water-way causes the iluidto pass through it, then to be divided into numerous tine streams while traversing said passages, and finally to escape at said outlet, for the purpose described.

2. The combination, in a ball-cock, of a moving water-way operated by a float, a counterbored seat against which said waterway closes, and a series of small dischz'u'geiassz'tges between said eounterbored seat and the common outlet of the cock, whereby the retraction of said water-way causes the i'luid to pass through it, then to be divided into numerous tine streams while traversing said passages, and finally to escape at said outlet, for the purpose described.

3. The combination, in aball-cock, of easing A 15 M, moving water-way I), having pack ings C 0, channel E, and port c, the valveseat .I, having perforationsj, the cap I, having a discharge 1', and the lever F, pivoted to said casing and operating said water-way, all as herein described.

In testimony whereof I ai'iix my signature in presence oi. two witnesses.
