WILLIAM LLOYD GILCHRIST, OF ALBANY, OREGON.
AUTOMATIC HYDRAULIC BALL OOCK.
Application led June 2, 1925. Serial No. 34,398.
My invention relates to ball cocks for use in toilet flushing tanks, cisterns, overiiows and in any and all places where it is desired to control the filled level of the liquid to b e removed therefrom through the siphonic principle or through valved control mechanism. v
My invention consists of new, novel and useful means for accomplishing this wresult by automatic hydraulic means.
My device consistsl primarily ofv a valve adapted to being quickly opened, and when closed to have cushioning means provided for t-he prevention of a water hammer.
A further object ofrmyA inventionconsist ing ina cam actuator, adapted to having imparted thereto, two speeds of opening. one to crack the valve, or to break the initial set of the valve, and after this has been accomplished, a quick opening of the same through the cam pawl engaging a sloping surface on its opposite end adapted to increase the speed of opening thereof.
A further object of my invention consists in the quick release of the camV actuator.
A further object of my invention consists in providing a splash skirt around the 'outer periphery of the valve cock body to confine the liquids escaping therefrom, and thereby preventing a splashing of the escaping liquids.
With these and incidental objects in view, the invention consists in certain novel features Vof construction and combination of parts, the essential elements of which are set forth in the appended claims and to a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.
Fig. 1 is a side elevation, partially in section, of my assembled device, illustrating'thev relation of the different .partsand in 'position, within thevalve cock. Y
Fig. 2 is. a front elevation, taken on line I 2--2 of Fig. l, looking. in the direction indicated.
Fig. 3 is a side elevation of the valve cock bOCly with the automatic mechanism removed" therefrom.
lFig. 4 isa side elevation ofthe valve stem, shown removed from the valve cock.
Fig. 5 is a side: elevation of the automatic escapement unit, shown detached from the valve cock, illustrating the escapement, the cam actuator, and the ball carrying arm as a unit assembly.
F ig. 6 is ak rear view looking in the direction indicated by the arrows in Fig. 5.
Like reference characters refer to like parts throughout the several views.
l is the body of the valve cock having a longitudinal cylindrical opening 2 therethrough, adapted to the passageof the valve stem 3 therethrough, the side walls of the valve cock body forming suitable bearing for maintaining the same in alignment and in position. A tapered inner wall 4, is disposed on the inner surface of the valve cock body, its slopingfsurface 'terminating at the longitudinal cylindrical opening therethrough, formingV the guideway for Vthe valve stem. The valve stem'3 has a collar 5, adapted to engageu with the tapering side walls of the valve body, lso that as the valve is seating upon the 'seat 10 of the valve body, a quantity of the liquid will be trapped within the enclosure 7, and will escape about and past the collar 5, to lessen the water hammer that` would be otherwise created by the instantaneousclosing of the liquid passage through the valve. A valve face S, of suitable valve material,` as rubber, is disposed about the valve head 9, disposed on the lower end'of the valve stem. The
maintaining the valve stem in approximatev position.v rlhe body ofthe valve cock is threaded at l2, for attachment to an inlet liquid conduit. The liquid as released from Vthe conduit has a tendency. due to the inrrushing velocity, to normally maintain the Avalve in closed position." To attuate the same, fa levery arm :13, is'journaled about the pin la. The ball rod 15, is attached to the lever arm The float ball 16, is yat-` tachedto the ball rod15. rl`he lever arm 13, is journaled about the pin 14, but is not attached thereto in rigid relationship, having a pivotal relationship therewith, but the actuator escapement 17, andthe cam actuator Y l@ are secured in iixed relationshipwith the n pin 111, andas the same is rotated about thev rotating axis of the pin, the pin is rotated also. The full line position of the ball rodthe end of the valve stem and partiallyv open; the valve and that afterwards the upper face 2O of the cam actuator will contact with the sloping surface 21 of the body portion and quickly move the valve into its full open position. ln the full 'open position the actuator lescapement will occupy thev dotted line position vshowin in liig. 1.. Then thev valve is closed by the pressure within the liquidv supplying pipe the valve stem isf raised to maximum height, and as thesame is raised the cam 18; and `the pin" 1li, journ-aled within the elongated sloty 22,:-is raised to the top oi' the elongated openingV v vhich position it remains until the cani contacts with the sloping surface at whielii time the pin 14: is carried to the bottom of thefelongatedopenln. thisjposition. the cani" contactsZ with the stop shoulder 26 andy the,y same is locked by the. upper end of the cani eng'agir-its;l with the horizontal ledge 25; until the liquid haa escaped from thek container to be emptied?, thej outflowing of the liquidis usually miuch more rapid than the infllowing `and therefore the container will be quickly emptied. 'Eo prevent the splashing o1'y the liquids enteringthroughv `the val-ves, VJrho same escapes through openings 2l, ofV the body of the valvefcock and to prevent the ,samen from splashing or otherwise@ escaping fromI the container; l' have provi-ded aci-rcumferential skirt portion 28, so that theI incoming liquid is Vdeflected' downward by the skirt portion. vAfter.the. eontainer has beenvv emptied usually by the s iphonic pti-nc'iple,` the, ball 16, is raised by the incoming liquid-and in rising, the armi 13, engages with the surface 211. of the escapementact-uator andi ini raising thesaane, theY cam is dis- 1 Ven gapgzclufrom the. ledge surface25, of .the valve cock body and,r 'the pressure on. the
valve steml closesthe valve and. in doing` so returnsfthe actuator'mechanism to its nor mally closed aindinopeiative position,.,and
the 1d i's carried tothe top of the elony gated: bearing. In the event/[that the pressure should cease and the liquidbe drained from liquid conduit attached to the valve body the tank Would drain through the valve.
One of the things accomplished by a device of this kind is the elimination of the customary noises that generally prevail.
In my invention l have produced a deviceV that is silent and efficient in its operation. One of few parts and one that will not easily get out of'order. Y
Vhile the form of mechanism herein `shown and described isk admirably'adapted to fulfill the objects primarily stated, it is to be understood thatit is not intended to con-fine the invention to the one Vforinof'embodiment hereinA showin and described,-4 as itv susceptible ofi embodiment in various formls,;,all com-ing within the `scope of the claims which fol-low.
