SPECIFICATION forming part of Letters Patent No. 685,928, dated November 5, 1901.

Application tiled March 29, 1901. Serial No. 53,526. (No modeh) To @ZZ whom, it may concern:

Be it known that I, JOSEPH W. NETHERY, a citizenof the United States, residing at Indianapolis, inthe'county of Marion and State of Indiana, have invented certain new and useful Improvements in Valves, of which the following is a specification,

The principal objects of my said invention are to provide a valve or faucet by means of which a predetermined amount of fluid may be drawn, whereupon the faucet will automaticallyclose, and to secure in such a faucet or valve certain advantages of construction and arrangement, as will be hereinafter more particularly described and claimed.

Referring to the accompanying drawings, which are made a part hereo fand on which similar reference characters indicate similar parts, Figure 1 is a side elevation of a valve or fauceteinbodyingmysaidinvention; Fig. 2, a central vertical sectional view of the same as Seen when looking upwardly from the dotted line 2 2 in Fig. 3; and Figs. 3 and et horizontal sectional views as seen when looking downwardly from the dotted lines 3 3 and 4E 4, respectively, in Figs. l and 2.

The iluid enters my improved valve or faucet by way of a pipe 1, first flowing np a prolongation 2 thereof, which forms the valveseat, and thence downwardly through the chamber 3 and out through the nozzle 4. Above and resting upon the part 2 (which, as above stated, forms the valve-seat) is the main valve 5, which is contained within a cylinder 6, which cylinder I prefer to form of glass, as shown. Upon the upper end of this cylinder is a head 7, and Ithis is connected to the upper portion of the shell of the chamber 3 by rods 8. Packing 9 and 10 at the lower and upper ends, respectively, of the glass cylinder 6 is provided as a means of maintaining fluid-tight joints. A transverse perforation 11 in the head 7 connects centrally with the interior of the cylinder 6 and at the outer portion with one ormore of the hollow rods 8, and these constitute a by-pass from the Vchamber formed by the cylinder 6 back to the chamber 3. I have shown all of the rods 8 as tubular, and consequently adapttion with the interior of the cylinder G by I means of its cup-leat- hers 15 and 16. It has a central perforation extending therethrough, through which a small stream of water from the main pipe 1 may pass up into the chainber formed by the glass cylinder G. It also has a prolongation 17 extending downwardly from its central point, the lower end of which is always below the upper surface of the valve-seat and the upper end of which registers with the perforation through the body of the valve, so that the fluid under the full pressure which is maintained inthe pipe 1 may always flow through the valve `to the chamber above. As this centralperforation through the valve 5 is directly below valve 12, the fluid passing through said perforation would if not prevented strike said valve 12 with considerableforce, and thus might sometimes close it before the proper time. Ihave therefore provided a shield 18 on the top of the valve fand over the mouth of this perforation, against which the fluid will strike and be spread out sidewise instead of being permitted to flow vertically upward against the valve 12. The latter is therefore permitted to close gradually and uniformly as the operation progresses.

In operation any one wishing to draw water (or such other fluid as a valve or faucet is used with) will first press down 'on the head h of the valve-stem 13, thus opening the valve 12. rIhe bylpass being larger than the perfox-ation through the valve 5, the pressure in the chamber in the cylinder G will at once be reduced, as the fluid will flow out faster than it will enter. The valve 5 then under the force of the uidrin the pipe l will rise oi its seat, so that the Huid will iiow through said Valve-seat, Iirst entering the chamber 3 and then passing out through the nozzle 4. As the valve 5 rises it comes in contact with the valve 12, closing the latter. The pressure then begins at once to increase in the chamber formed by the cylinder (i, and as the area of the upper end of the valve 5 is considerably greater than the valve-seat at the upper end of the part 2 this increased pressure begins at once to force the valve 5 downwardly, and it presently reaches its seat, whereupon the tiow of the fluid is stopped and willso remain until the valve-l2 is again opened. The speed with which the chamber maybe emptied through the by-pass of course depends upon the size of said by-pass, and in order that this may be regulated to suit and the amount of I'luid to be drawn at one opening of the valve 6 determined at pleasure I have provided below each of the frame-screws 19 a suitable shut-ott screw 20, which is capable of being driven in until it closes the by-pass. As is obvious, this can he adjusted as desired, and any required result thus obtained.

There is an advantage in the use ot the chamber 3 as a receptacle for the discharge from the by-pass rather than to deliver it directly into the nozzle of the faucet, as the chamber being considerably the larger of the two the fluid enters it more freely than it could enter the comparatively small nozzle. In the arrangement shown also, where the valve-seat is above the top of the chamber at the point the by-pass discharges into said ingress-pipe, a chamber arranged at the terminal of said ingress-pipe, a nozzle leading out from said chamber, an extension to the ingress-pipe leading up centrally through said chamber and forming the main-valve seat, a valve above said valve-seat, acylinder within which said valve is contained, a by-pass leading from said chamber around said cylinder and communicating therewith at the upper end, and a small valve to said by-pass.

2. The combination, in a valve, of the main ingress-pipe, a glass cylinder arranged above said pipe, a valve within said glass cylinder, an extensionpipe from the maiupipe forming a valve-seat for said valve, a cap above said glass cylinder, an orifice forming a part of the by-pass, a valve to said by-pass, and tubular rods leading from said cap to said chamber and constituting both connectingrods and a part of the by-pass, substantially as set forth.

3. The combination, in a valve, of the main ingress-pipe, a cylinder above said pipe, a valve in said cylinder having a longitudinal perforation therethrough leading from below to above said valve, a shield arranged over said perforation to receive the flow of fluid therethrough, a by-pass from the upper end of the chamber in the cylinder above the main valve back to below said main valve, and a small valve to said by-pass; said shield serving as a guard to prevent the jet ot water from the orifice in the main valve from striking the by-pass valve, substantially as set forth.

4. The combination, in a valve, of a glass cylinder within which the valve proper operates, a head to said cylinder, and tubular rods connecting said head to the structure below, said tubular rods being arranged to serve also as a portion of the by-pass, substantially as set forth.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 27th day of March, A. D. 1901.
