JOHN lll/'ILLlAl- "WLLIAMSGN, OF WESTHRTGN,
SCOTLAND.
SLUCE OR GATE VALVE.
Application filed December le, 1920.
T o @ZZ w )tom it may concern Be it known that I, JOHN illimitati' REA llTiLLiAMsoN, a subject of the King of the United Kingdom oi Great Britain and lreland,r and residing at lllesterton, Dumbartonshire, Scotland, have invented a. certain new and useful improvement in Slnice or Gate Valves, of Which the following is a specilication.
The subject of this invention is a sluice or gate valve the closing of which under the action of a spring is controlled from a remote position.
The present invention consists in the einployment of toggle mechanism adapted, when straight, to hold the valve in open position and capable of being bent by means operable from a dist-ance so as to permit the valve to close under the action ot the spring.
The invention is illustrated in the accoinpanying dranf'ings in which Fig. l is an elevation partly in section and Fig. Q is an elevation partly in section at right angles to Fig. l.
As shown, the valve l fitted to the spindle 'l is urged by a spring 2 towards closed position and is sustained normally in open position by a toggle meclianism comprising upper toggle links 3 pivoted to a. cross head secured to the valve spindle 'l and lower toggle links 5 pivoted at G on the valve casing 7, and connected at S to the upper toggle links. To the connection 8 are attached tripping arms l0 which are connected to a cord or Wire 13 wrapping the pulley i4; and operable troni a distancey The tripping arms l0 are adapted to swing int-o an inop-- erative position in which the enter end oit each t i ping arm engages a ledge 'll on the valve casing `whereby the toggle device. is prevented 'troni becoming accidentally bent. For holding the toggle mechanism in substantiallyv straight position slightly beyond the dead centre, there are termed on the valve casing lugs l2 against which abut the lower toggle links 5.
lt will be understood that, when the valve is to be closed the cord 13 is tensioned, whereby the tripping arms l0 are first brought out of engagement with the ledge ll and are then moved to bend the toggleo Serial No'. 430,645.
l claim l. rlhe combination oit' a valve, a spring for closing the valve, a toggle device serving when substantially straight to hold the valve in open position. and means operable troni a. distance tor bending the toggle to permit the spring to close the valve.
2. Valve mechanism comprising the comu bination of a valve, means tending to hold the valve in closed position, and a toggle which when substantially straight holds the valve in open position, and means i'or bending` the toggle to permit the valve to close.
3. Valve mechanism ooi-nprising the coin bination oit a valve, means tending to hold the valve in closed position, and a toggle which when substantially straight holds the valve in open position, locking means for preventing accidental bending` ot the toggle, and means tor rendering the locking means inoperative and bending the toggle to permit the valve to close.
4t. "i/Talve mechanism comprising the coinbination ot a valve, means tending to hold the valve in closed position, a toggle which when in substantially straight position slightly beyond the dead center holds the valve in open position, means for limiting the lilending ot the toggle beyond this substantiall straight position in one direction, and means tor bending the toggle in the other direction to permit the valve to close.
5. Valve mechanism comprising the combination of a valve, a spring tending to hold the valve in closed position, a toggle which when in substantially straight position bevond the dead center holgl.; (be valve in iiniiling the bendiligv ond this subs rIntially c, lir tion, a :ipping Ytoi preventi o accidental bending ol: the toggle in, the other direction, and means For tripping the tripping :ivm and bending the toggle beyond the d :ad center to permit tbc spring to close the valve.
ln testimoniY whereof l; have signed my naine to this speoilication in the presence oit 'tivo subscribing witnesses.
