REGULATED AUTOMATIC-CLOSING VALVE.

Specification of Letters Patent.

Patented July 16, 1912.

Application filed. December 28, 1910. Serial No. 599,774.

To all whom it may concern:

Be it known that 1, JOHN LINCOLN GISH, a citizen of the 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, of which the following is a specification.

The object of my present invention is to construct a regulated automatic closing valve, in such a manner, firstly, that the water in the tank will be retained under direct pressure, until the said water is required for flushing; secondly, thatthe water in the tank will be discharged in a large volume, under direct pressure, into and through the valve-casing; thirdly, that the flushing stream, after passing the outlet 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 closedautomatically, the apparatus be ready, to repeat its work, as hereinafter described.

Figure 1, is a perspective of my improved apparatus. Fig. 2, is a vertical section thereof, with the valves 1)., and K., in the closed position. Fig. 3, is a vertical section thereof, with the valve 1)., open, and the valve K., closed. Fig. i, is a vertical section thereof, with the valves 1);, and K., in the open position. Fig. 5, is a vertical section thereof, with the valveD., closed, and the valve K., open. Fig. 6, shows the regulating plate R, adjusted to a different position, in order to regulate a shorter flushing stream.

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

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

In Fig. 1,E., is the tank, fastened fluidtight, to the removable valve-casing T. 1., is the inlet, to the tank 1). T., is the valvecasing. P., is a face plate, fastened fluidtight, to the valve-casing T. R, is a regulating plate; 0., is a stop pin, in the regulating plate R; 8., is a slot in the regulating-plate R; 88., is a set screw, which fastens the regulating plate R, to the face plate P. H., is a handle; 0., is a counterbalance, to handle H. to an operating spindle, which passes through the face plate P. 0., is the outlet to the valve-casing T. The usual connec- (L, is a set nut, joining the handle H,

tions with the service pipe, and the discharge pipe, are made at 1., and 0., respectively. A., is a supporting arm,'projecting from the inside of the valve-casing T., and engaging the spindle S. S., is an operating spindle, which passes through the face plate P, (Fig. 1,) at a. 13., is a finger, firmly fixed, upon the spindle S. (L, is a valve stem, to the valve D. 1)., is the relief valve, to the valve K. (Z., is the valve seat, to the valve 1)., in the-valve K. 22., is the conduit, from (Z., through the valve K., at some point removed, from the central aXis of the valve K. m., is an adjustable weight, attached to the valve stem (L, by the set pin L K., is the main valve; K., is its flat valve seat, in the valve casing T. T., is a removable casing, which incloses the main valve K., and forms a part of the valve casing T. O'., is an inlet, to the casing T., from the tank E. X., is a chamber, in the casing T., above the valves 1)., and K.

The special features of my device are described as follows :The main valve K., is a heavy weighted valve (not buoyant) which slides up and down in the valvecasing T., in such a manner, so that it is only, by or with great pressure, that air or water, can be forced or filtered, between the outer wall of the valve K., and the inner wall of the casing T. The said valve K., has a con cave bottom, so as to form an annular ring, on the bottom of the said valve K.; and the said annular ring contacts the flat valveseat K.

The weighted vent-valve 1)., is recessed, in the top of the valve K., and its solid stem (L, projects through the main valve K. The solid stem (L, is so constructed, that it slides, so snugly, up and down, in. its passage way, through the valve K., that when the ventvalve 1)., is opened, no air or water, escapes along the line, of the valve-stem (L Hence, by such a construction, with no lateral motion, to the solid stem (L, the valve 1)., with its recessed valve-seat (L., is assured of a positive seating, upon its valve-seat (Z, p ro viding the adjustable weight m., is attached to the valve-stem (L, by the set pin L, as will be explained below.

it-h such close coadaptation of surfaces, of the valve 1)., and its solid valve-stem (L, with the valve K., and yet give complete ventilation to the valve 1)., when opened, it

is necessary to provide a conduit, through the valve ii, at some point removed from the central axis of the valve ii; which said conduit will begin at the lower edge of the valve-seat (.Z., and open or end, in the bottom of the valve hi; as for example, the conduit its to the adjustable weight 171., which is attached to the valve-stem (Z, by the set pin 2 the said weight 772., performs special work, besides acting as a stop, to limit the distance, the valve 1)., is raised from its 'alve-seat (Z., or to act as a part of the means, which raises the valve K., after the valve 1)., has been opened namely, the said weight 772 is the force or means, which draws quickly, the valve-stein (L, back to its starting position, thereby assuring a quick and positive reseating of the valve 1)., after the means, for opening the valve 1)., has broken contact, with the valve-stem cl, and also, after the valve 1)., has been rescated, by the action of the weight 1a., the said weight 122., holds the vent-valve 1)., upon its valvcseat (Z., as the main valve 121., descends to its valve-seat K., thereby otl'ering a great resistance to the air, which is trying to reenter the chamber X., through the conduit and the valve-scat (Z., as the main valve 1a., descends to its valve-seat K.

In the act of the opening of the valves 1)., and K., we displace through the conduit .22., the air and water, that may have been confined within the chamber X. New, by a prearranged relation of parts, we allow the valve 1)., to close, and leave the valve K, suspended within the casing l see Fig. 5. This suspended relation, of the heavy weighted alve 1i, Fig. 5., is in proportion, to the assembling of the parts, 'lC., K., 1)., (L, and my whereby we govern, the balancing of the force of gravity, which acts upon the valves, and the pressure beneath said valves. And this is accomplished, by hav ing the device so constructed, and the parts so assembled, that it is only, by or with greatpressure, that air or water, can be forced or filtered, into the chamber X, between the outer wall of the 'a-lve IQ, and the inner wall of the casing T., and since air, cannot easily or quickly, reenter the chamber X, by way of the conduit and the valveseat (Z., by reason of the fact, that the valve 1)., is held down, upon its valve-seat (Z., by the weight 7a., which is attached to the valvcstem (2., it is readily seen, that we have gradual control, over the air, which is try ing to reenter the chamber thereby giving us a gradual, regulated, self closing of the valve H. You will notice that I say, control over the air, which is trying to re enter the chamber X. The reason for this statement is,-that when the valve K, be gins to close, the tank 1*), is practically empty of water, and the valve IQ, being so far removed from its valve-seat KC, there is nothing but air, to find its way, into the chamber X. And also by way of reference, would say, that the device is so formed, that the contents of the tank ll, is expelled, at some little time, before the valve K., is closed, thereby allowing for an extra amountof water, to tlow from the inlet 1., into the tank E, and to pass directly, to and through the valve-seat KC, and thus serve, as the quantity of water needed, to refill the closet bowl, after the closet bowl. has been flushed, and before the valve K, is closed.

The means, employed to open the valves l), and K, becomes a feature,-not in the way the valves 1)., and K, are opened; but as soon as the valves 1)., 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 l)., by means of the weight 9a.; thus performing a specific act or function, in leaving the valve 1i, suspended in the casing T., see Fig. 5., for a predetermined time. in order to regulate, the self closing of the valve K.

liith the special features thus described, my device, performs its work as follows: ln Fig. the valves 1)., and ii, are in the closed position. ater is allowed to enter the tank lth, through the inlet 1. into the said tank Pl, water will 'tlow, until the air, within the tank it, has been compressed, to

an equal degree, with the water pressure,--

from the service pipe. As the tank E, is tilled. with water and compressing the air therein, as soon as the air and water pressure, within the tank 1 has become. of a sutlicient pressure, to overcome, the resistance, that is offered, to either air or water, by the close ceadaptation of the outer wall of the valve hi, and the inner wall of the casing T., then and not befor water passing through 0, will be forced between the two said surfaces, of the valve IQ, and easing T.; and. this forced filtration, between the outer wall of the valve l l, and the inner wall of the casing T., will be continued, until the air within the chamber 21., will be of the same compression, as the air within the tank This compression of air and water, within the chamber 31., will force the valve hi, downward, upon its valves+at K., and assin'e a positive closure, of said valve K.

in Fig. 3., the operating means, ll, 8., and P, are shown, as having opened the valve and thereby relieved. the chamber 31., from its pressure of confined air and water; said air and water having been discharged, tl'irough the valve-seat (Z., and the conduit 22., downward, through the valvc seat K. The quantity of water, that has been confined, within the chamber FL, is so small, that it is not considered of a flushing nature. Now, with the pressure removed from the chamber X., by the opening of the valve 1)., a full downward motion of the handle 11., will operate the means, 11., S., 1%., (Z, and 7a., which will easily push the main valve K., upward into the chamber X., and away from the valve-seat K., Fig. 4e, and allow the contents, of the tank E., to pass into the opening O., and directly through the valve-seat K., into the discharge or flushing pipe, at 0.; and in the act of discharging,the water in the tank 13., is forced into the flushing pipe, under the heavy compression of air, aforesaid, that has been confined within the tank E.

As soon as the valve K., Fig. 5., has been pushed up into the casing T., and the handle 11., is released, the counter-balance 0., returns the handle 11., which rotates the spindle S., to which is firmly fixed the finger 13., back to their starting position; thereby breaking contact, with the valvestem cZ-., which act, allows the immediate closure of the valve 1)., by means of the weight 77%., which is attached to the valvestem (L, and leaves the valve K., suspended within the casing T'., as shown in Fig. 5.; and as stated above, the valve K., Fig. 5., will descend slower or faster, in proportion, to the assembling of the, parts, T., K., D., (Z., and m., and thereby return the parts, to their respective positions, as shown in Fig. 2., and leaves the device ready, to repeat its work.

The regulating means R, 8., 88., and 37., performs its work as follows :-1n Fig. 6., the dotted lines, show position of the regulating plate R, adjusted so that the handle 11., can make a full downward motion and open the valve K., to its fullest extent, for a full flushing stream, before the handle 11., comes in contact, with the stop pin 37. Now in order to make a shorter flushing stream, the regulating plate 1%., is adjusted as shown in Fig. 6., bringing the stop pin 29., closer to the starting position of the handle 11., thereby limiting the downward motion, of the handle 11.; and the shorter we make the downward motion of the handle 11., by the re-adjusting of the plate R, the shorter will be the opening of the valve K., and the shorter, the opening of thevalve K., the shorter the flushing stream, will be.

From the above description, it will be noticed, that the first, second, third, and fourth objects, of my present invention, as above mentioned, are fully accomplished.
