To all wlumt it mag comm.-

Be it known that I, ALBERT FULLER, of Brooklyn, in the county of Kings-and State of New York, have invented anew anduse ful Improvement in Tank-Regulators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification. Previous to my invention a 'contrivance has been employed for so regulating the supply of water to tanks and reservoirs that whenever the water should reach a certain height or the supply of water to and in the tank or otherreservoir has consisted in a suitable valve arranged to close upward and against the pressure of the water in the discharge: pipe, said valve having combined with it a lever hinged at one end to the lower part of the supply-nozzle, and provided at the other end with a float, the whole so arranged and operating (in a manner well known to those skilled in the art) that the closing and reopening of the valve would be automatically effected by the rise and fall of the lever-float on the surface of the water in the tank; but such tank-regulators have been found in practice to be very objectionable, on account of the noise and jar occasioned during the closing of the valve. This noisy action of the contrivance has been caused by the vibratory or tremulous movement of the valve laterally during its upward movement or passage to its seat in the supply-nozzle; and in cases where the head or pressure was considerable, the violent and noisy action of the valve device has rendered the use of the contrivance most objectionable.

The principle of construction of tank-regulators, as made prior to my invention, has been such that whenever the supply-column, with its usual fluctuations of head, was of considerable pressure and volume, the valve would necessarily rattle in coming to its seat,

because, being supported at the lower end ofits stem by a pivotal connection with-the floatlever, and being forced upward to its seat by the impositiveflaction of avlever actuated merelyby a floatpthe efl'cct of the water'i'n its passage around-3nd: past the valve, while the latter wasfree-mrtnnrble or mbvelaterally on its pivotal pblei'ioflsuppertfiantli -flminfluence it exerted t'crrkeep'r :the valve amiggrlirom its seat, whilaet-he. valve-closing lever was actu:

ated only by'the uncertain forceof'the float, tended necessarily to hold the valvein a state of agitation near its seat until the-float should, positively overcome this tendency, and dur-' the valve, of means for holding'and guidingp laterally its stem, and insuring a central and positive motion of the valve toward its seat, as will be hereinafter more fully described.

To enable those skilled in the art to make and use my improved tank-regulator, I will now more fully explain its construction and operation, referring by letters to the accompanying drawings, in which- Figure 1 is a vertical section, and Fig. 2 a

sectional plan (below the line w an at Fig. 1) o it.

a is that portion of the fixture which is, as usual, connected to the supply water-pipe, and which is extended downward at b (in a sort of L shape) to form the water-way, in which works the valve-stem, and the further exten-- sion of which, as at d, forms the valve-chamber. k is a lever, pivoted at 1, (below the valve-chamber 11,) provided with a float-hall, m, and guided between the bars at u, all about as usual, and f is the valve, by preference of rubber, properly secured by a clamping-nut, i, in the valve-stem g, the lower portion or base h of which is pivoted in the usual manner, and, as clearly shown, to the lever h. To

the valve-stem g, near its upper end, .is applied, as shown, a screw collar or washer, formed with three (more or less) arms, 0, which radiate from the stem g sufficiently far to come into contact with the walls or sides of the wa-' tor-way b,and which form guides to hold or steady the stem 9 laterally during its movement endwise within the passage b.

The general operation of the described contrivance is about like that of the tank-regulator heretofore made and used, the water passing from the supply-pipe through a and b, when the valve f is open, (or down from its seat,) and the supply being-cut off by the clos-' ing of the valve as the float m rises, and causes the lever k to lift the valve; but, unlike the contrivances heretofore made and used,the one shown and described is provided with means (the arms 0) by which the upper '-endof the valvastem, or that end which is usually free to vibrate, is held or guided lat erally, and eflectually prevented from trembling as thewalve comes toward its seat, so that no great or fluctuating may the prefle'uieof the supply-column there can be no jar or rattle, and consequent noise, in the valve device of the apparatus.

Of course, in carrying out my invention, some other than the particular device shown of radiatingarms 0, working against the walls or interior of the water-way b, may be used to effect the guidance or retention, laterally, of the pivoted valve-stem, for the purpose of preventing the possibility of any vibration and noise, the gist of my invention resting in the use, in connection with the valve, of a suitable device or means for efiecting the proper control, as described, of that end of the valvestem which has heretofore been left free to vibrate about the point of pivotal connection of the valve-stem with the actuating floatlever.

What I claim as new, and desire to secure by Letters Patent, is-

Incombination with the valve of a tankregulator, pivoted at the lower part of its stem to the float-lever, and closing against thepressure of the supply-column, means for guiding or laterally holding the uppereud of the stem of said valve, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand and seal.

ALBERT FULLER. [1,. s.]
