FLUSHING-VALVE.

Specification at' Letters Patent.

Patented June 3.

Application filed May 2, w12. Serial No. 694,635.

To all whom i may concern Be it known that I, JOHN L. Baena a citi.

invented certain new and useful Improvements in Flushing-Valves, of which the'following: is a full, clear, and exact description.

This invention relates to improvements in flushing valves to vfaterclosets, of 'a kind to be employed from the direct lpressurc supply and Without the use of the customary tank.

ln the description of valve to which this invention relates, the valve is provided with means. for manually opening,l it, and provided with means, such as a spring, for closing it upon the release of the opening force; and it hes in conjunction therewith a controller whereby the closing ot' the valve under spring i.. retarded in 'order to give a sufficient Water delivery to the bowl."

The .present invention more particularly pertains to .a controller which is etiective to cause the retardation of the closing action of the valve for as protracted a period of valve closing action as may be predeter mined arranged for.

The inventionis described in conjunction 'with the accompanying drawings and is set forth in the claims.

In the drawings z-F igur'e l is a vertical sectional view through a valve to have connection with a 'Watercloset bowl or like` apoliance and thi'ouvh the novel devices for controllingsuch valve the parts being),n shown normal positions.

in its closing action, as in their closed or Fig. 2 is a central sectional view through the controller but showing the parts as in their positions when the valve is opened. Fig. 3 is a cross sectional view on line 3-3, Fig. 1. Fig. 4 is a Side elevation of the upper part of the Valve I corresponding' stein. Fig'. 5 a view similar to Fig. 3, but showing;- a slight structural variation. filip?. (3 is en elevation of the apparatus; and lipjs, i and 8 are cross sections on lines ii' and'8-8, Fig.

vt'iiniilar characters of reference indicate parts in all of the views.

ln the dmivings, it represents the valve5 the inlet a, otivhich is to he connected *.to n direct pressure Weiter supply, and by the loutf let a2 has connection with 'the Water closet bowl.

b2 represents a main valve seat in the valve body A7 seating on which 1s the valve ?1, and through which the valve stein is passed, the same having a lost motion play through the perforated web or spider 3,

and having a head orI enlargement it et its lower end for engagement with the portion 3 of the main valve lor lifting the letter from its seat, o? beingan auxiliary 1relive seating on and to close the opening,y throng. the main valve.

The valve stein B is extended and guided through a gland in 'the top of the valve iiody and extends through a suitable gland therefor into a cylinder D, which is supported above the valve body by,A the extension frame J.

E represents the piston closely 4iii-.ted in an intermediate part of the cylinder chainber, dividingr the vlatter into upper compartment :v and lower compartment y.

The valve stem B has et its upper end a diametrical enlargement or head Whiclnas 'shown and for practicability of `construction, is formed separately from the stem and screw connected therewith.

o represents a passage extending axially in the headl and .in a portion ot the stem below such head, terminating in a transverse port o2 opening` to the upper compartment :n and in a transverse port e3 opening int-o the lower cylinder compartment y.

The screw plug g having a tapered end is a provision ot Well lknown kind for varia- A bly restricting the passage which forms a cennnunication between the upper and lower compartments.

The valve stein is formed With an abuti ment or shoulder l1, disposed a suitable distance below the enlarged head f,-tlie distance between the shoulder and such head beingslightly greater than the length or.`

height of the piston E through which" the` stem is slidable for lost inotion engagement with the piston. The stein in the portion from its hond f down to a point belowv the shoulder IL is reduced or recessed, preterably on several sideslas shown at t', to forni passages through the piston which ere normally 'closed through the co-action ot the piston und the valve stein head which acts loo as a valve in relation4 to said piston and as seen in Fig. 1.

-be filled with a liquid, such, for instance, as

oil or glycerin. z

Assuming the parts to be in the position shown in Fi l, then by depressing the lever G to lit the valve stem B and raise l the valves d and b from their respective seats, such rising action of the valve stem will cause a movement of-the valve stem head f upwardly away from the to of the piston, opening the passages i, andt e-shoulder or abutment z, then coming tov engagement with the under side of the piston will lift it, causing the displacement of the liquid from the upper compartment a' through .the passages i 1nto the lower cylinder compartment fz, as will be understood on referring to Fig. 2. Immediately the force against the valve operating lever G is released, the springs will be effective' for impar-ting an endwise movement to the valve stem in the valve closing direction, and therefore etfective for bringing the valve stem head firmly against the top of the iston and cutting ofi' the communication or the flow of liquid from the lower compartment mvinto the upper one through the passages a'. lThere 1s, however, the ever present commmication between the compartments through the passage v and its 'branches or ports fue, o",

' cylindrical hub m,

but this being such a restricted yone, the valve will close slowly accordin to the regulation of the degree of restriction, while the plston descendin under lthe spring pressurev is slowly disp acing the liquid from of the valve stem head. i

' It will be noted that tlie body of the flushf ing valve A is made with an upstanding and with' a plurality of sockets n at quarters and in a common circle concentric of said hub;

The cylinder D is supported by a'frame J on which the valve operating lever Gr is fulcrumed, and which frameat its lower portion is constructed with a clamping yoke KV which is constricted and loosened by operating .the binding screw o, such yoke having an encirclingengagement about the said up standing huh. The base'portion of the suporting frame J is provided with a depending dowel p for engagement in any of the several sockets n.

The vprovisions described permit of the revoluble adjustment of the liushing valve A relatively to the cylinder, its supporting frame and the operating lever G so that such valve may be positioned for receiving its connection with the water supply at any side thereof as may be available in different situations. Y

The frame J which makes the connection between the body of the flushing valve and the regulating device therefor is formed with a dove tailed offset lug g which is tapered in its length, and which lug has a supporting engagement in a bracket plate M formed with a vertically tapered way having undercut edges.

The cylinder is shown as formed with a threaded opening s centrally through its top in which an externally threaded sleeve or tubular screw t is engaged, the lower end of such sleeve projecting more or less as dcsired below the upper end wall of the cylin der to form an adjustable abutment for variably limiting the endwise opening movement of the valve stem. The opening through the top of the cylinder renders the adjustable passagerestricting screw plug accessible to be turned when the closing cap u is unscrewed from the cylinder top.

Incases where the pressure of the water supply is extremely high, a lessened length of opening movement of the valve stem is to be permitted, while in places where the pressure of the water supply is low a longer opening thrust is to be imparted to thc valve stem;

l I claim;- the lower into the upper cylinder compartl. rlhe combination of a valve casing haw ing a lateralinlet and a terminal outlet, a duplexyalve controlling said outlet, said valve comprising an annular main valve carrying an apertured depending spider and 'an auxiliary valve seating on said main valve, a stein passing through the annular main valve and apertured spider and provided at its terminal with a head normally spaced .from said spider' but adapted to engage therewith in the opening of the duplex valve, said stem also carrying said auxiliary valve and passing through said casing and terminating in an apertured end, a supporting member mounted rotatably and adjustably on said casing and having dowel pin connection therewith, an operatinglever pivoted to said member and also having pivot connection with said stem, a dash pot cylinder secured to said supporting member and receiving the said apertured valve stem end,

llt

isn'

a spring acting on said valve stem to returntlie duplex valve to closed position.

2. A flushing valve comprising a stem projecting vertically and upwardly therefrom having at the top of its body an upletandintgr huh, an inelosed casing into which the valve stein extends, located aloove the valve. means in said inelosed casing eop erating with the valve stem for exerting a retarding action against the closing movement ot the stem, and a frame by which the easingie supported, having at the lower portion thereof a clamping yoke revolubly adjustahly engaged about the said upstanding huh of the valve body. said valve body and damping yoke having, the one a plurality ot.' sockets, and the other a dowel engalgeahle in any one of said sockets.
