,. `To all lwhom z't may concern Be it known that I, JOHN LINCOLN GIsH, a citizen ofthe United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented a new and useful Regulated Automatic-Closing valve in such a manner; rstly, thatthe water in the tank, will be retained under direct pressure, until the said water is required for flushing; secondly, that the' water in the tank will be discharged in a large volume, under direct' pressure, into and through the valve-casing; thirdly, that the iushing stream, after passing the out-let in the valve-casing, performs no other work, Or

function, but that of flushing; and fourthly,

' after the flushing has been completed, for

the regulated automatic closing valve, to be closed automatically, the apparatus be ready, to repeat its work, as hereinafter described. .i

Figure l., is a perspective of my improved apparatus. Fig. 2., is a vertical section thereof, with-the valves D., and K., Iin the closed position. Fig. 3., is a vert-ical section thereof, with the valve D., open, and the valve K., closed. Fig. 4., is a vertical sec. tion thereof, with the valves D., and K., in

, the open position. Fig. -5., is a vertical'section thereof, with the valve D., closed, and the valve K., in the open position.

lIn the drawings, self closing valves, of the reciprocating type are shown.

Like letters of reference, refer to like parts, in the several figures.

In Fig. 1.,-E., is the tank, fastened fluid vis the inlet to the tank E. T., is the valvecasing. P., is a vface-plate, fastened iuid tight, to the valve-casing T. H., is a handle; C., is a counter-balance, to the handle II.; a., is a set-nut joining the handle H., to an operating spindle, which passes through the face-plate P. O., is the outlet, to the valve-casing T. The usual connections', with the service pipe and the discharge pipe are made at I., and 0., respectively. A., is a supporting arm projecting from the inside of tne valve-casing T., and engaging the spindle S. S., is an operatingA spindle, which passes through the face-plate P., (Fig. l.) at a. B., is a finger, firmly fixed,

passes.

uponthe spi'ndle S. d., is a valve-stem, to the relief-valve D. D., is the relief-valve, to the main valve vK. df., is the valve-seat, to the valve D. o., 0. 0., is an inlet, a passage-way, and an outlet opening, through the valve-stem d., for Ventilating the valve ;D., when opened. m., is an adjustable we1ght, attached to the valve-stem d., by the ,set-pin z'. n., n., is a plate, of a suitable gnature, to' hold the valve-seat material d., into place. K., is the main valve; K., is itsvalve-seat. T., is a removable casing, :which incluses themain valve K., and forms, a part of the valve-casing T. O., 0., are inlets, to the valve-casing, part T., from @the tank E. X., is a chamber, within the casing 'I"., above the valves D., and K.

The special features of my device are deiscribed, as follows g-The main valve K., is a gheavy weighted valve, (not buoyant), which .slides up and down in the valve-casing T., '1n such a manner, so that, it is only, by lor @with great pressure, that air or water, can be forced or filtered, between the outer Wall Vof the valve K., and the inner wall of the casing T. The said valve K., has a concave bottom of such a degree, that a thin cutting edge, is formed, on the bottom ofsaid valve Said cutting edge, contacts with the valve-seat K.; the valve-seat K., being made of any suitable material, which will allow the said, t-hin lcutting edge, of the valve K., to be impressed therein, and thereby, form a positive seating or closure. The weighted vent-valve D., has a concave botT tom, forming a thin cutting edge, which contacts with the valve-seat d.; the said Yvalve-seat d., being made of any suitable material, which will allow the said, thin cutting edge, of the valve D., to be impressed therein, and thereby2 form a positive seating or closure. The said vent-valve D., has a valve-stem d., projecting through the vcentral aXis, of the main valve K., entirely filling the aperture through whichit passes; and yet, the said valve-stem d., is allowed to slide up and down, in its passageway, through the main valve K.; but, when the vent-valve D., is opened, -no air or water, can pass, between the outer surface of the said valve-stem d., and the inner Wall or surface, of the aperture through which it I-Ience, by such a construct-ion as stated above, the vent-valve D., is assured of a positive seating or closure, upon its valveseat d., providing the adjustable weight m.,

is attached to t-he valve-stem ci., by the setpin 2'., as will be explained below. l

lVith such a close coadaptation of surfaces, of the valvevD., and its valve-stem d.,

5 with the valve K., and yet, give ventilation to the valve D., when o-pened, it is necessary to provide a passage-way, for such ventilation. And. this is accomplished as follows At a point, below the under surface of the vent-valve D., there is an inlet'opening 0., into the said valve-stem al.; this said lnlet opening 0., is continued, downward, into a passage-way 0'., on the inside of the' valvestem d., and ends in an outlet opening 0., near the lower end, of the said valve-stem d., thereby, providing complete ventilation for the vent-valve D., when said valve D., is opened. It is also a noticeable feature, that when the vent-valve D., is closed, the pasn sage-way o., 0'., 0., has a double closure, by means ofthe valve D., with its valve-seat d., and by reason of the fact, that the inlet o., in the valve-stem d., has passed below the upper surface of the valve K., and down into the aperture through which the valvestem d., passes; thereby, making a double guard, against leakage, by Way, of the ventvalve D. As to the adjustable weight m., which is attached to the valve-stern d., by the set-pin 2'., the said weight m., performs special work, besides acting as a stop, .to limit the distance, the valve D., is raised from its valve-seat d'1; or to act as a part of the means, which raises the valve K., after t-he valve D., has been opened ;-namely, the said weight m., is the force or means,lwhich draws quickly, the valve-stem d., back to its starting position, thereby assuring a quick and positive reseating of the valve D., after the means, for opening, the valve D., has broken contact, with the valve-stem d.; and also, after the valve D., has been reseated, by the action of the weight m., the said weight m., holds the vent-valve D., upon its valve-seat d', as the main Avalve K., descends to its valve-seat K.; thereby offering a greater resistance to the air, which is trying to renter the chamber X., through the passage-way 0., 0., 0., and by way of the valve-seat 02'., as the main valve K., descends to its valve-seat K. l

In the act of the opening of the valves D., and K., we displace through the asse-geway 0., 0., 0 the air and water, tiiat may have been conned within the chamber X. Now, by -a prearranged relation of parts, we allow the valve D., to close, and leave the valve K., suspended within the casing T., see Fig. 5. This suspended relation, of the heavy weighted valve K., Fig. 5., is in proportion, to the assembling of the parts, T., K., D., d., d., n., n., and m.; whereby we govern, the balancing of the force of gravity, which acts upon the valves, and the 65 pressure beneath said valves. And this is renacer accomplished, by having the device so -const-ructed, and the parts so assembled, that it is o`nly, by or with great pressure, that air or water, can be forced or ltered, into the chamber X.,'between the outer wall of the valve K., and the inner wall of the casing T. And since air, cannot easily or quickly renter the chamber X., by way' of the passageway 0l, 0., 0., and the valve-seat d., by reason of the fact, that the valve D., is held down, upon its valve-seatd., by the weight m., which is attached to the valvestem d., itv is readily seen, that we have a gradual control, over the air, which is trying to reenter the chamber X., thereby giving us a gradual, regulated, self-closlng of the valve K., and maintaining the double guard, against leakage, by way of the vent-L valve D., as related above.

You will notice fthatl say,-control over the air, which is trying to reenter the chamber X. The reason for this statement is,m that when the valve K., begins to close, the tank E., is practically empty of water, and the valve K., being so farl removed from its valve-seat K., there is nothing but air, to ind its way, int-o the chamber X. And also, by way of reference, would say, that the devine is so formed, that the contents of the tank E., is expelled, at some little time, before the valve K., is closed; thereby allowing for an extra. amount of water, to flow` from the inlet l., into the tank E., and to pass directly, to and through the valve-seat K., and thus serve, as the quantity of Awater needed, to rell thecloset bowl, after the closet bowl has been flushed, and before the valve K., is closed.

The means employed to open the valves D., and K., becomes a feature,-not in the way the valves D., andv K., are opened; but as soon as the valves D., and K., are opened, the said means, by releasing the operating handle H., breaks contact, see Fig. 5., with the said valves, and allows the immediate closure, of the valve D., by means of the weight m.; thus performing a specific act or funotlon, in leaving the valve K., suspen'ded, within the casing Tf., see Fig. 5., for a predetermined time, in order to regulate the self-closing of the valve K.- f

With the special features, thus described,

my device performs its work, las follows In Fig. 2., the valves D., and K., are in thev -closed within the tank E., has been compressed, to

an equal degree, with the water pressure,`l

from the service pipe. As the tank E., is filled with water and compressing the air therein, as soon as the air and water pressure, within the tank E., has become of a' sufficient pressure, to overcome, the resistance,l that 1s offered, to either alr or water,

.the chamber -of air, aforesaixll, 'that` has by the close co-adaptation of the outer wall of the tank K., and the inner wall of the casing T., then and not beore,- water passing throu h 0'., 0., will be forced between the sai the casing T.; and this forced filtration, between the outer wall of the valve K., and the inner wall of the casing T continued, until the air within the X., will be of the same compression, as the air, within the tank E. his compression of air and water, within the chamber X., will force the 'valve K., downward, u` on its valve-seat K., and assure a positive c osure, of said valve K.

In Fig. 3., the operating means, H., S., and B., are shown, as havin opened the valve D., and thereby raised t e valve-stem d., so as to exfposc the opening o., above the top-surface o the valve K., and relieving X., from its pressure of conwater, by way of the passageof. downward, through the rlzhe quantity of water, that has been confined within the chamber X., is so small, that it is not considered, of a Hushingnature. Now, with from the chamber X., by the openingl of the valve D., and of the pa Y -way o., of., 0., a full downward motion of the handle H., will operate the means, H., S., B., d.,and m., which will easily push-the main valve K., upward into the chamber X., and. away from the valve-seat K., see Fig. 4., and allow the contents of the tank E., to pass into the openings O. 0., and directly through the valve-seat K into the dischar e or ushing pipe, at 0.; and in this act org discharging, the water in the tank E., is forced into the flushing pipe, under the hea compression n confined,

within the tank As soon as the valve K., Fig. 5., has been pushed up, to the casing T., and the hanchamber fined air and way o., o

valve-seat K.

surfaces ofthe valve K., andv will be the pressure removed 8^ dle H., is released, the counter-balance'C., returns` the handle H., which rotates the spindle S. to which is rmly xed the lin er back to their starting osition; there breaking contact, with tile valve-stem which act, allows the immediate closure of the valve D., and simultaneously the inlet opening o., of the passage-way o., 0'., 0., is dropped back, into theaperture, through which the valve-stem d., passes, by means of the weight m., which 1s attached to the valvestem d., and leaves the valve K., susgended within the casingfT., as shown in ig. 5.; and as stated above, Fig. 5., will descend, slower or faster, in proportion, to the assembling of the parts T., K., D., d., d., n. n., and m., and thereby return the parts, to their respective positions as shown in Fig. 2, and leaves the Adevice ready, to repeatits work.

From the above descriptiomgit will be noticed, that the objects of my present in vention, as above mentioned, are fully accom lished.

at Ido claim as my invention, and desire to secure, by Letters Patent is,4

A duplex valve comprising an apertured casing inclosin a main valve' and an auxiliary valve, sai main valve havln a gasket securedv to its upper portion an.' forming between the caslng and the main valve a packing means, the inner portion of said the valve K.,
