UNITED STATES PATENT oruuon.

BALL-COCK FOR WATER-TANKS.

Specification of Letters Patent.

E'atenteo. July 25, 1905.

Application filed January 12, 1905. Serial No. 240,732.

To all whom it may concern.-

Beitknown that I, J OHN E. BURDELL, acitizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Ball-Cocks forWater-Tanks, of which the following is a specification.

This invention relates to certain improvements in ball-cocks for water-tanks for supplying water to water-closets and other purposes; and it consists in certain novel constructions and arrangements of parts whereby simplicity and economy are attained, the device rendered easy to repair, the internal parts made readily accessible, and the noise produced by the vibration of the wall of the tank, to which most ball-cocks are secured, nearly or quite done away with.

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which Figure 1 is a sectional view of a water-tank of the style adapted for use in connection with water-closets, my apparatus being shown in elevation. Fig. 2 is a sectional view of the operative parts of the apparatus, the valve being closed. Fig. 3 is a sectional view of the said parts, the section being taken at right angles to that illustrated in Fig. 2 and the valve being open. Fig. 4 is a horizontal section taken on line i 4, Fig. 2. Fig. 5 is a horizontal section taken on line 5 5, Fig. 2.

Similar letters of reference indicate corresponding parts.

(0 represents the tank, Z) the outlet-pipe, and 0 the pull-chain and its connecting parts, all constructed as usual and making no part of this invention.

My improved apparatus is not secured to the wall or side of the tank nor to any portion thereof, but is attached, by means of a plate or bracket (Z, to the wall of the building or apartment in which the tank is located, or it may be secured to the ceiling. Integral with this plate is a branch 0, to which is screwed the end of the supply-pipef and a branch g, which is connected by a coupling 72 with the upper end of the pipe 2', whose lower end is connected-by a coupling-pipe 7a with the upper end or wall Z of a cylindrical case or structure m, said Wall being provided with a screw-threaded passage for the reception of the thread on said pipe 75. The upper end of the pipe k is formed with a head a to receive a wrench in order to adjust it in the casing m with relation to the valve therein. A suitable nut n serves to retain the parts in position. From the inner surface of the case an there extend radially opposi'e supportingbrackets 19, preferably integral with the case, said brackets sustaining centrally in the case a vertical tube 1), in which slides vertically a hollow circular valve, consisting of the walls (1 and top 0, on which is secured a washer s, which constitutes a seat for the lower end of the pipe 75 when the valve is raised, as in Fig. 2. This hollow valve is sustained by the head 6 of a lifting-rod at, whose lower bifurcated end is pivoted at a) to the lever 20, which has rigid with it a horizontal tubular hub 00, which extends between the extensions y of the lower portion of the wall 177. of the case. A pivot-pin 2, threaded at one end and provided with a thumb-piece at the opposite end, extends through holes in the extensions 1/ and through the hub 00, as illustrated in Fig.

5. The lever M has screwed into it the ordinary lever j, which connects with the float 0. WVhen the chain is pulled and water let out of the tank through the ordinary outlet mechan ism, the lowering of the float 0 draws down the rod u t from the position indicated in Fig.

2, allowing the valve 9 q to drop away from the lower end of the pipe it, allowing the water to pass through the pipes f and g, the coupling 7t, and the pipes 2' and 75 into the case m and around the tube 1) and the walls q to the lower open end of the case m, thence into the tank between the extensions y. When the chain is released, the float rises, carrying with it the rod a, head t, and valve 0 g from the position indicated in Fig. 3 until the washer 3 seats itself against the lower end of the pipe 76, stopping the inflow.

By removing the pivot-pin or thumb-screw e the parts inside the case are rendered accessible and removable, whereby they may be repaired or others substituted for them.

Inasmuch as the plate or bracket (Z is not secured to the tank, but to the wall or ceiling of the building or apartment, the unpleasant noise produced by the vibration of the wall of the tank is entirely avoided and done away with.

As the pipe 713 is adjustably connected with the pipe 2', which extends up to the supply, said pipe I; can be readily lowered by applying a wrench to the part a when the lower end of the pipe becomes chafed off.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a ball-cock of the character described, the water-suppl y pipe secured outside the tank to the building or apartment containing said tank; a pipe connecting with said supply-pipe and extending down into the tank at an appreciable distance from and out of contact with any portion of the tank; the case 110 provided on its inner surface with a concentric guiding-tube; a hollow valve adapted to slide in said tube; a pipe screwing into the upper end of the case and adjustably connected with the pipe which extends down from the supply; a float-lever pivotally secured to the lower end of the case; and a lifting-rod connected with said float adapted to move said hollow valve upward against the lower end of the pipe which extends down into the tank, all the said parts extending down from the supply into the tank out of contact with any portion thereof, for the purpose set forth.

2. In a ball-cock of the character described, a water-supply pipe secured outside the tank to the building or apartment containing said tank; a pipe connecting with said supply-pipe and extending down into the tank at an appreciable distance out of contact with any portion of the tank; the case on provided on its inner surface with a concentric guiding-tube; a hollow valve closed at its upper end and adapted to slide vertically in said guidingtube; a pipe ad justably connected as to height with the pipe which extends from the supply and extending down into the tank; a float-lever pivotally secured to the lower end of the case; and a lifting-rod pivotally connected with the float-lever and provided with a head which extends up into the hollow valve and against its closed upper end, whereby said valve may be lifted against the lower end of the adjustable pipe which extends down into the tank, all said parts which extend down into the tank being held out of contact with any portion of said tank, whereby vibration of the walls of the tank and the noise produced by such vibration are prevented.

In testimony whereof I have signed my name to this specification in the presence of two sul scribing witnesses.

JOHN E. BURDELL.
