FLUl-D-FLOVV-CONTROLLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 713,788, dated November 18, 1902.

Application filed January 2l, 1902.

To @ZZ when@ t may concern:

Be it known that I, JOSEPH W: NETHERr,

a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Fluid-Flow-Controlling Devices, of which the following is a specification.

The object of my present invention is to :o provide a means which when a fluid-outlet is opened will permit the iiow to continue for a certain predetermined period (or quantity) and then automatically shut it off. An ap paratus embodying my said invention will be first fully described and the novel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar zo parts, Figure l is a central vertical sectional view through so much of a huid-delivering apparatus as embodies my said invention and illustrates one type of said invention; Figs. 2 and 3, horizontal sectional views, on an enlarged scale, as seen when looking in the directions indicated by the arrows from the dotted lines 2 2 and 3 3, respectively, in Fig. l; Fig. 4, a View similar to Fig. l, illustrating an alternative construction; Fig. 5, a View 3o similar to a portion of Fig. 4, but on an enlarged scale; and Figs. 6 and 7, horizontal sectional views, on an enlarged scale, as seen when looking in the direction indicated by the arrows from the dotted lines 6 6 and 7 7, 3 5 respectively, in Figs. 4t and 5.

The pipe l0 is a fragment of any ordinary Huid-conveying pipe and leads from any suitable source of supply. (Not shown.) From a suitable fitting secured to the end of this 4o pipe two conduits lead to any ordinary fiuidoutlook, as a cock or faucet. One of these may be a plain conduit, having no special peculiarities, or it may be constructed specially, as for convenience or to improve the appearance. In Fig. fl one of these conduits is shown in line with the pipe l0 and the other to one side and connected thereto by suitable fittings, thus forming a Huid-conduc- Serial No. 90,668. Idilo model.)

tor arranged as a by-pass around the devices vembodying the construction peculiar to my 5o invention. In the construction illustrated especially in Fig. l the huid-conductor is larger than and incloses a smaller tube containing the devices peculiar to my invention. Otherwise the two forms are substantially the same, the differences being of a mechanical character and unimportant. As is entirely obvious, the operation of both forms is precisely the same, while the constructions are equivalent.

Referring now again especially to the form illustrated in Figs. l to 3, inclusive, I provide a suitable fitting ll. on the end of the pipe l0, to which are secured the two tubes 12 and 13, one of these tubes (in this particular ar 65 rangement) being inclosed within the other, so that the main fluid-conductor is the annular space between the two through which the iiuid passes to the ordinary faucet 14, which is shown as the outlet or iiuid-de- 7o livery device. Within the inner tube 13 is a cartridge-shaped traveling valve 15, which is adapted to be forced up said tube into contact With a seat provided therefor in the fitting 16, which constitutes the upper end of the structure of which the tubes 12 and 13 are the body. As is obvioustwhen this seating takes place the flow of fluiu 1s shut off, except so far as a slight leakage is permitted, by the groove u or some similar or 8o equivalent formation. The traveling valve l5 is actuated by the pressure of the fluid passing through a small perforation 17 in a transverse partition 18, forming part of the structure and located at the lower end of the tube 13. This perforation l7is made adjustable in size by means of the needle-valve 19. Surrounding the perforation 17 I provide other perforations 20. In a small chamber situated below the partition 18 is a washer 2l, 9o (preferably of leather or rubber,) having a single central opening, so that the central perforation 17 shall never be obstructed thereby, but imperforate as to the remainder, so that when it is in contact with the under side of the partition 18 the holes 20 therein shall be closed thereby. The central orifice in this washer is of considerably less diameter than the diameter'of the opening leading thereto from below, so that a considerable portion of its under surface is exposed to the force of lthe liuid coming toward it through the pipe 10, and thus said washer is raised against the said partition 18 by said force except when there is a greater pressure thereon from the fluid from the other side.

The operation of my apparatus is as follows: The various devices being at rest and in the positions shown and it being desired to draw the predetermined quantity of fluid, the fluid-outlet, as the faucet 14, is opened, whereupon the iiuid will begin to tlow in the regular and ordinary manner therethrough. Pressure above the travelingr valve 15 being reduced, the pressure of fluid passing in through the orifice 17 will begin to force said traveling valve upwardly. At the same instant the fluid-pressure will cause the washer 2l to rise against the under side of the partition 18, thus closing the perforations 20. As ythe quantity of iiuid passing through the orifice 17 is small, the traveling valve 15 will move slowly, its speed being governed by the size of said orifice, which,-as above stated, may be regulated by means ot' the needlevalve 19. When said traveling valve reaches its seat, however, it of course at once stops the flow of iiuid and will remain seated, thereby preventing the tiowof any more luidsolong as the duid-outlet is open, so that no pressure can accumulate above said traveling valve. When the fluid-outlet is closed and the pressure above the traveling valve becomes equalized with the pressure below or behind it, (which occurs very shortly on account of the slight leakage which is permitted past said traveling valve when seated,) then the traveling valve will begin to descend because of its own gravity and will presently arrive at its initial position just above the partition 18, as will be readily understood. The descent is rendered more rapid than the ascent by reason of the holes 2O in the partition 18,

Vv-theSwL-being uncovered and put into condition to permit the fluid to pass by reason of the washer 2l dropping away and leaving them free, which it will do as soon as the traveling valve begins to descend, the descent of said traveling valve causing a slightly greater pressure above than below said washer.

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

1. The combination in a'fiuid-supply system of a fluid-outlet, a Huid-supply leading thereto, a valve-seat behind the outlet between it and the main Huid-supply, a second tube or pipe below said valve-seat, a traveling valve therein, a horizontal partition near the lower end of said tube or pipe containing perforations, a traveling washer formed to cover certain of said perforations and leave part of said perforations uncovered, which washer is mounted to move back and forth in a chamber below s'aid partition and is adapted to be operated by the water-pressure to close against said partition when the fluid is flowing through the apparatus and the traveling valve is rising and to separate therefrom and leave the perforations open when the Valve is descending, substantially as set forth.

2. The combination in a fluid-supply system of a fluid-outlet, a supply-pipe leading thereto, a valve-seat behind the outlet, a second pipe below said valve-seat, a traveling valve therein, a horizontal partition near the lower end of said pipe containing perforations, a needle-valve projecting into one of said perforations for varying its size, a traveling washer mounted in a short chamber beneath said 'chamber and formed to cover the perforations therein except the one provided with said A4needle valve, which washer is mounted to travel Aback and forth in said chamber below said partition and is adapted to be operated by the water-pressure to close against said partition when the I'luid is iiowing outwardly through the apparatus and the traveling Valve is rising and; separate therefrom and leave the perforations open when said traveling valve is descending, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at'Indianapolis, Indiana, this 14th day of January, A. D. 1902.
