JOSEPH W. NETHERY, OF INDANAPOLIS, INDIANA.
AUTOMATlCALLY-CLOSlNG VALVE.
'SPECIEIGATN forming part of Letters Patent No. 668,202, dated February 19, 1901.
Application filed April 30,1900. Serial No. 14.999. (No model.)
Be it known that l, JOSEPH W. NETHERY, 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 Automatically-Closing Valves, of which the following is a speciiication.
The object of my present invention is to produce a valve which will automatically close.
A valve embodying my said invention will be tirst'fullydescribed,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 parts, Figure 1 is a side elevation of a valve structure embodying my said invention;and immediately adjacent parts, and Fig. 2 a central vertical sectional view of the same.
The fluid enters the valve through the ingress-pipe l and passes off through the discharge pipe or mouth 2. The parts and e constitute the valveoasing and valve seat structure, the valve-seat proper being formed on the upper end of said part et, as is shown in Fig. 2. The valve 5 is in form a pistonvalve and is situated within the casing 3, which is much larger in diameter than the opening through the valve-seat, and it fits tightly in said casing at the upper end, being there provided with a packing 6. A suitable packing '7 is also provided to rest onto the valveseat when the valve is closed. Extending down below the valve 5 and into the opening in the valve-seat is a cylindrical projection 8,which guides the lower end of the valve in its movement. This part 8 has triangular openings in its sides, and as the valve rises in operation these openings as they pass above the valve-seat form graduallydncreasing orifices through which the fluid may pass. The opening and closing of the valve is thus rendered very gradual.
Extending around from below the valveseat to above the valve is a by-pass lO. The orifice thus leading to the chamber above the valve is comparatively small,and at one point, as at p, Fig. 2, is constricted somewhat', so that the flow of the fluid from below to above the valve shall be slow. This can be reguthereafter.
lated also by means of a regulating-screw 11, the point of which can be driven in nearer to or farther from the point p, thus partially or wholly closing the orifice at that point, as will be readily understood. The outer end of said screw or closer should be covered by a cap 12 to prevent it from being disturbed after it is properly adjusted. A second bypass 13 leads from the chamber above the valve 5 to the discharge-pipe, which is larger in diameter than the by-pass 10 or least larger than the constricted portion of said by-pass at the point p. The discharge end of this bypass where it enters the discharge `pipe 2 should be curved outwardly in the direction leading toward the point of discharge in or der that the iiow through said by-pass shall mingle properly and easily with the liquid passing through said dischargepipe. l have found byexperiment that this is quite an important minor feature of construction and adds very materially to the efficiency of the operation. A valve 14 is provided for this bypass 13. This may be in the form of a ball, as shown in Fig. 2, and it may be so arranged as to be forced back against the discharge orilice from the by pass 10, so as to completely close the same when the by-pass 13 is opened, although Ido not desire to oonflne myself to this arrangement. A pushrod l5, having a thumb-piece 16 on its outer end, is provided for operating this valve 14, and a spring 17 serves to hold said pushrod outwardly except when force is applied thereto.
The operation is as follows: The main valve being in closed position, as shown in Fig. 2, and it being desired to draw liquid, the operator pushes in the'push-rod 15, thus opening the valve in the by-pass 13 and permitting the liquid above the valve to iiow out th rough said by-pass into the discharge-pipe 2. The pressure of the liquid in the supply-pipe 1 will then cause the valve 5 to rise, opening a free passage through said main valve from the ingress-pipe to the discharge-pipe. This free passage will be maintained as long as the by-pass 13 is held open, and, Where equipped as shown in this figure, for a short time When, however, pressure on the push-rod 15 is released and the valve 14 permitted to close, then the pressure of the liquid which passes around through the by-pass into the chamber above the valve 5 will exert such a pressure on the upper end of said valve (which is, as .will be readily observed, of considerably-larger diameter than the opening through the main valve-seat) as will close said main valve automatically, thus shutting off the dow. The flow in closing is shut off gradually by means of the triangular openings in the cylindrical projection 8, as it is increased gradually in opening.
By means of the adjusting-screw 11 this valve may be adjusted to discharge any predetermined quantity of liquid, as the time of the flow will obviously be determined by the relative size of the openings in the by-passes 10 and 13. In case of desiring the regular quantity of liquid and no more the user simply pushes in the push-rod 15 and releases it instantaneously. The valve 14 will then gradually close, as the pressure in the chamber above the main valve 5 is increased by the iow of liquid through the by-pass 10, and as soon as the valve 14 is completely closed and the liquid in said chamber has had time to reach the proper pressure the main valve 5 will of course also close.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patenti, is-
1. The combination of a Valve, a by-pass leading from the ingress-pipe around said valve to the chamber above it, and a second by-pass leading from said chamber to the egress-pipe leading from said valve, the discharging end of said last-named by-pass being curved outwardly whereby the discharge therefrom is caused to coincide with the discharge through said discharge-pipe, substantially as shown and described.
2. The combination, in a valve structure, of the ingress-pipe with its inner end formed as a valve-seat, a cylindrical valve-casing of considerably-larger diameter than said ingress-pipe mounted with its lower end surrounding said inner end of the ingress-pipe, a discharge-pipe leading therefrom, a pistonvalve mounted at its upper end tightly in said casing and having a lower face formed to ft upon the valve-seat on the end of the ingresspipe, a by-pass extending from below the valveseat to the chamber above said valve, a by-pass leading from the chamber above the valve to the discharge-pipe, and a valve in said last mentioned by pass, and means whereby the operator may open said by-pass valve, and means for automatically closing it, all substantially as set forth.
3. In a valve structure, the combination, of the ingress-pipe formed with a valve-seat on its inner end, a Valve-casing surrounding said end and mounted thereon of a larger diameter, a piston-valve mounted in said casing, its upper end being fitted to slide therein and its lower end being formed to seat on the end of said ingress-pipe and having a cylindrical structure depending therefrom into said ingress-pipe formed with triangular openings through its sides, a by-pass leading from below the valve to the chamber above it, and another leading from said chamber to the discharge-pipe, valves in said passes, and said discharge-pipe, substantially as set forth.
In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 27th day of April, A. D. 1900.
