Sept. 30, 1952 J. D. LANGDON VALVE CONSTRUCTION Filed Nov. 25, 1944 T llllllik Il fl... H
Patented Sept. 30, 19-52 I if. ooNs'rmio'rro v v The instant invention pertains to valve construction whereby the component parts. of the valve are chiefly constituted by the supply line of a liquid control valvel'with the objects in view of economical construction and manufacture .together with silencing features constituted ;by means for changing the flow. of liquid under'pressure to a gravity flow. 1} I Otherland furtherobjects and purposes will appear as the specification and operative description proceeds as illustrated by the drawings which showonly one form of reduction to practice which may be changed within the scope of the'claims. Of the drawings: i Fig. 1 is a sectional view as at l-l of .FigI 2 showing supply tube S forming .theIinlet I, outlet slots OS with valve member "open VMO, closed position shown by dotted. lines VMC, operating lever 01, and restricted inlet opening IO. vFig. 2is a top plan of which Fig. 1 is 'a'sectional view. Fig. 3 is asection as at 3- '3, Fig.2. Fig. 4 is a separate top plan of pressure converter cup PC. I l e Fig. 5 is a separate sectional view of converter cup PC, showing gravity ports GP. 7
The instant invention consists ofa supply tube S forming aliquid inlet I andhaving outletslots OS cut for a distance downwardly fromthe upper end of tube S; a plug-like valve member in. open position VMO inserted into said tube S, the slots OS being of greater length than said valve member VMO. The opposite walls of the slot OS form of the slot OS forming an outlet for liquid under pressure passing from the supply tube S beneath the valve member VMO andoutwardly into the pressure converter cup PC which is enlarged to form a sump or cup oi ample capacity to permit liquid to rise therein co-acting with gravity ports GP perforated thru an upwardly extended sleevelike portion of the cup PC surrounding the tube S; the ports GP providing drain means for the cup PC. The gravity ports GP are preferably made triangular in form with a point of the triangle directed downwardly so as to permit any rise of liquid in the cup PC to flow therefrom at a proportionately faster rate as the liquid level in the cup PC rises. As the liquid level decreases the area of the ports GP decreases in proportion 9 Claims. (Cl. 137592) to insure the projection of liquid 'at..maigimum velocity against the outer wall of the supply'tube S down which the liquid pas'singfrom the cup PC runs by gravity. Stream director SDsurrounds the ported tube S and directs liquidflowing. from ports O'S downwardly. f p
Special attention is called to the fact that a head of liquid rises in the chamber of cup PC to a point above outlet OS and serves tosmother flow of liquid into the chamber and quietrthe valve. 1 I i l, Any running liquid RL flowing down the outer wall of the supply tube S maybe controlledby any shape of ports GP which may bedesired'to meet the conditions of liquid pressure flowing from the ports OS. However actual tests have proved thatthe restricted area ,formed by the downwardly projected apex of the ports GPforms a. trough-like V,-shaped outlet which projects liquid against the tubes with the greatest efjficiency as the liquid level in the pressure con ,verter cup PC diminishes due to the :closure'of the ports OS whenithe operating lever 0L is depressed at] its outer end. the valvelfmember is permitted to assume, open position 'VMO., closed position of the valve VMC, shownin'Fig fi', is assumed when the outer end .of lev' Li s raised. -A washer Wis, shown inserted in lthe supply tube Shaving the upper surfacel'thereof"disposed at a point substantially at the level .of thevalve member closing line VMC, the washer Whas an inlet opening IO in the center thereof whichjmay be proportioned tosuit any condition of liquid pressure and control the rate of liquid flow,with relationto the capacityof the cupPC and [the area of the ports GP. p "I If. it is desiredlto use thedesoribe'd valve asa ball-cock in a toilet flushing tank the device is installed with the outlet OSfandth'e cup PC' a suitable distance above any overflow outlet which is a conventional element in the construction of a toilet flushing tank to prevent backflow of liquid when subatmospheric condition of, pressure exists within supply passage Sof riser I. ,A- float may be attached tothe operating lever OL to control the opening and closing of the valve.
A suspending ring SR is formed above the ports GP of the cup PC and serves as means to support the cup PC when pressed over the outer circumference of the supply tube S. I
It is preferable to have the valve member VMO formed of resilient material with a cup-shaped closure end, the concavity thereof facing the inlet opening IO and the outer edge thereof being sub- I It will be seen that the described device is a 7 cross connection eliminator and therefore this application is a continuation in part of Ser. No. 389,436, filed April 19, 1941, and now abandoned.
Having described the invention and the operation thereof, the following claims are made;

A device as of claim 6 wherein the outflow means from thecup is formed by apertures facing the inlet tube, an imperforate annular shelf ei f rmed, by t e bottom. of. the up etween the upturned surrounding portion of the cup forming the wall of an annular chamber whereby the head of liquid from the Valve outlet is accumulated andrises above said outlet aiding to smother and quiet flowof liquid into said cup.
8. A device as of claimfi wherein the outflow means is formedby triangular apertures facing the inlet tube, an apex of the triangular aperture being pointed downwardly whereby flow of liquid from said apertures; is concentrated and slowed down as the level of the liquid head in said cup is lowered by diminished delivery of liquid thru the valve outlet during closure of the valve.
9. A device as of claim 6 including a cuplike structure surrounding the outlet means of the valve, the open end of the cup facing downwardly whereby liquidis directed downwardly into the first named cup.
