NEEDLE-VALVE.
Speciication of Letters Patent.
Patented Mar.. 2, 1920.
Application filed July 2, 191B. Serial No. 243,020.
State of Vir inia, have invented certain new and useful mprovements in Needle-Valves,
of which the following is a specification.
This invention relates to valves; and the object of the same is to produce improved means for adjusting the needle of' a needle valve to restrict the inlet of fiuid.
Another object is to provide means for regulating the degree to which said needle ma be adjusted.
igure 1 is a vertical sectional view showing the mounting of the needle and the mechanism for projecting it manually and for limiting the degree of adjustment of which it is susceptible.
Fig. 2 is a plan view-of Fig. 1,
Fig. 3 is an elevation taken from the right side of Fig. 1, A
Fig. 4 is Ia fragmentary detail of a slight modification.
1n the preferred embodiment of the present invention, *about to be specifically described, 1 designates the needle which is reduced at its lower end to a point 2, which coacts with an appropriately shaped seat S at the inlet of the casing P. By my invention I' mount the needle slidably within a tubular guide 3 socketed at its lower end at 4 to receive an enlargement or shoulder 5 on the body of the needle so that the latter may not be opened at all beyond a certain extent; and the guide is herein shown as supported by being screwed into the casing P which has a. chamber C permitting movement of the shoulder 5; The needle valve or rod .rises through packing 6 within an `appropriate cavity at the top of the guide, and the rod threaded near its upper portion is shown. At the top of said guide is a tubular barrel 10 having at one side of its j upper end an upright notch 11, and within needle, and at the extreme upper end of the latter is a knob or cap 18.
Surrounding the barrel is a cli 20 supporting a bracket 21 which is forked at its upper end as at 22, and pivoted at 23 within the fork is a lever 24 whereof the lower arm overlies said knob or cap 18 and the upper arm may extend in almost any appropriate direction. In Fig. 1 it is shown as overlying the lower arm, and connected with it is a Wire 25 leadin to a proper point. In Fig. 4 what wouldgbe the equivalent of the upper arm is numbered 26, and the wire 27 leads in the opposite direction. It is the intention that this element 25 or 27 lead to a remote point where it will be within reach of the operator.
With the parts assembled as best seen in Fig. 1, in which the needle is at its upper limit with its shoulder 5 fitting closely within the socket 4 the maximum amount of liquid is passing through the inlet. When desired, the operator draws lon the wire 25 or 27 or by some other means moves the lever, and it bears on the cap 18 which pushes the needle downward. This motion carries with it the lock nut 17 which bears on the upper cup 13, and of course the spring 19 is compressed; hence it is necessary to maintain the tension on the wire in order that the restriction in the low of liquid shall be permanent. It will be seen from Fig. 1 that the needle cannot be pushed downward beyond the point where the lower edge of the periphery of the ouf) 13 strikes the shoulder 12. As this cup is screwed onto the threaded portion of the needle, its adjustment is eiiected by turning it and then setting the nut 17 above it; yet always leaving the pin 14 projecting into the notch 11 to prevent the cup from rotating, although it may still rise and fall. When the operator pulls on the Wirehe should be permitted to move the point 2 into the passage surrounded by the seat S only to a certain degree which will not be su 'cient to entirely cut off the How of fluid. Of course release upon the wire permits the parts to again take their original position, when the shoulder 5 rises into the socket 4 and the inlet is wide open. The lever may be given a variety of shapes according to requirement of the case.
The foregoing description and the drawings have reference to what may be considered and preferred, o1' approved forms of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, 'et cetera, as may prove expedient Iand fall within the scope of the appended claims.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
1. In a needle valve adjuster, the combination with a guide having a socket in its lower end, a needle valve slidably mounted through said guide and having a shoulder seating in the socket when the needle valve is wide open, and packing in the guide around the needle; of manually operable means for moving the needle valve to unseat its shoulder from the socket and to move the valve to closed position, a barrel surrounding the needle, an element adjustably mounted on the needle and coacting with the upper end of the barrel, and a nut on the needle above said element, for the purpose set forth.
2. In a needle valve adjuster, the combination with a guide having a socket in its lower end, and a needle valve slidably mounted through said guide and having a shoulder seating in the socket when the needle valve is wide open; of manually operable means for moving the needle valve to unseat its shoulder from the socket and to move the valve to closed position, a barrel surrounding the needle and seated on said guide, itsupper end being internally shouldered and one wall having an upright notch above the shoulder, a cup screwed on the needle and coacting with the shoulder, a pin on the cup loosely mounted in said notch, a spring bearing the cup upward, and a nut threaded on the needle above'said cup.
3. In a needle valve adjuster, the combination with a guide, a needle valve slidably mounted through said guide, and packing in the guide around the needle; of manually operable means for moving the needle valve to closed position, a cylindrical barrel mounted on said guide and having an upright notch in its upper end, a washer within said barrel, a cup coacting with the upper end of the barrel and having a pin loosely mounted in said notch, said needle passing through the washer, barrel and cup, a coiled expansive spring surrounding the needle between said washer and cup, and a nut threaded on the needle above said cup.
4. In a device of the class described, the combination withl a vertically .adjustable needle, a tubular guide in which it is slidably mounted, means for limiting its upward movement therethrough, a tubular barrel on the guide around the needle and having an upright notch, a cup adjustably mounted ou the needle and coacting with the upper end of said barrel, and a pm on the cup moving` in said notch; of a nut threaded on the needle. above said cup, a cap at the upper end of the needle, a clip embracing said barrel, a bracket rising from said clip and forked, and atwo-arm lever pivoted in said fork with one arm overlying said cap and the other adapted for'manual operation.
5. In a device of the class described, the combination with a vertically adjustable needle, a tubular guide in which it ,is slidably mounted, means for limiting its upward movement therethrough, a tubular barrel on the guide around the needle and having an upright notch, a cup adjustably mounted on the needle and coacting with the upper end of said barrel,l and a pin on the cup moving in said notch; of a nut threaded on the needle above said cup, a bracket whose lower end is supported on said barrel and whose upper end is forked, a lever pivoted in said fork with one arm overlying the needle, and a wire connected with the other arm and adapted to be led to a remote point, for the purpose set forth.
In testimony whereof I allix my signature in presence of two witnesses.
