Application liled March l2, 1900. Serial No. 8,343 ililo model-l To r/Z 7071/071?, 'it 77cm/ concern,.-

Be it known that I, WILBER J. PINE, a citizen of the United States, residing at Oshkosh, in the county of l/Vinnebago and State of Viscousin, have invented a new and useful Improvement in Flushing-Valves, of which the following is a specilication.

The object of my invention is to provide a simple and efficient valve for iiushing waterclosets or other places where iiushing is required; and the invention consists in the features and combinations hereinafter described and claimed.

In the accompanying drawings, Figure l is a sectional elevation of my improved flushing-valve; Fig. 2, an elevation, partly broken away, showing the upper disk open and the lower disk closed; Fig. 3, a perspective detail of the release and lock for the valve-stem, showing the parts separated; Fig. 4, a crosssection taken on line 4 of Fig. l looking in the direction of the arrow; Fig. 5, a detail showing a modification in the support and lock for the same; Fig. 6, adetail in perspective of the parts shown in Fig. 5, separated; Fig. 7, a detail showing a modification in the lock for the valve-stein; Fig. 8, a detail in perspective of the parts shown in Fig. '7; Fig. 9, a side elevation with the shell or casing partly broken away, showing the parts in position with the induction-passage open and showing a modification of the construction, arrangement, and location of the cushioning piston-chamber; and Fig. lO, a sectional elevation of the lower portion of the valve, showing the construction of Fig. 9 with the induction-passage closed and the relief-passage open from the lioat-chaniber.

In constructing my improved flushingvalve I provide a casting or shell A, having an inlet or induction passage A' and an outlet or ed notion passage A2. The shell around each of the passages has a wall or rim screwthreaded for the attachment of the valve to the supply and rilischarge pipes. The induction and eduction passages are separated by cushion to prevent the main disk from being closed too forcibly. The main disk D, as shown, is formed of a metal portion d and a packing dl, the packing' seating against the edge of the opening a in the wall a when the disk is closed. In the construction shown the main disk is screw-threaded onto the valve-stem C, so as to be adjustable thereon for properly seating the disk. The valvestem also carries a second disk E, oppositely faced to the main disk D, which disk, as shown, is also screw-threaded onto the stem and is adjusted and held in position by nuts or otherwise. This second disk enters au opening e in the outer wall of the main shell and seats against a flange at the bottom of the opening, so as to close a port c', and, as shown, a guide and support against lateral pressure on the valve-stem is furnished by an annular ri in or wall c2, partially encircling the saine and against which the faces of the adjusting and locking nuts bear in the movements of the valve.

A cylinder or shell F is screw-threaded onto the outer wall of the main shell or casing, forming a float Water-chamber for the admission of Water thereinto when the main disk is open, such admission being through a port f in the wall of the main casing. The port fis regulated and controlled as to the amount of water passed, in the construction shown, by a valve j", entered through a screw-threaded hole in the main shell or casing, which valve, as shown, is nicked at its outer end for the reception of a screw-driver or other tool, by means of which the valve can be advanced and receded to decrease or increase the size of the opening through the port ffor the passage of Water. The outer end of the valve is encircled by a rim or wallfg, forming a packing-box for the reception of a suitable packing compressed by a screw-threaded plug f3, so as to always insure a tight joint around the Valve, which is of course necessary to prevent leakage in adjusting the valve.

'Ihe float Water-chamber formed bythe casing F has located therein a float G, which is loosely mounted on the valve-stein and free to rise and fallin the chamber. As shown in Figs. l to 3, the bottoni of the float has secured thereto slotted pendants 'or lugs g, through the slots of which pass arm hof a lever II, forming one portion ofaknuckle-joint connection. The lever H is pivoted to a standard H', extending up from the wall of the main shell or casing, and has pivoted thereto two links h', one on each side, which links in turn are pivoted to a collar h2, secured around the valve-stem C. The lever H, with the links h and collar h2, constitutes a knuckle-jointconncction and furnishesalook for the valve-stem. The knuckle-joint connection should be free to break upward with the upward movement of the iioat, which releases the lock, and for this reason the pivots of the link to the valve-stem and to the releasing-lever and of the releasing-lever to its standard when the' stem is pushed inward to open the valve should be in line, or approximately so, for the weight of the fioat when down to hold the stem and its disk against outward movement. rIhe limit of the throw of the knuckle-joint downward should not be sufficient to produce a lock by the passing of the pivots beyond the dead-center that would not be released with the upward movement of the fioat to act on the releasing-lever, and to regulate and control the downward movement of the knuckle-joint, and from it the downward movement of the float, an adjusting-screw vl is provided, thatengages a stop t" on the lever H, limiting the point of descent or downward movement of the lever andlink 'movement in an upward direction when the fioat rises.

`The-shell or casing F has mounted on its end a lever I, arranged to contact with the end of the valve-stem for moving such stem to open the disk D and close the disk E, opening the main supply for liushing purposes and closing the discharge from the float-chamber, and at the same time allow the main supply to pass through the port finto the floatchamber.

The operation is as follows: When itis desired to iiush the basin, the lever I is pressed down, forcing down the valve-stem to open the disk D and close the disk E, which movement also carries the piston at the end of the stem downward. The Water-supply for iiushing purposes passes into the induction-passage A' through the openings around the casing B and enters the eduction-passage through the opening or port a. This supply passes out through the eduction-passage 'to the basin, and a proportionate quantity thereof, regulated by the valvef, passes through the port 6o fand rises in the float-chamber, causing the oat to rise. The upward movement of the float raises the lever H, releasing the knucklejoint connection, so that the pressure entering the induction-passage strikes the bottom of the diskD, raises the disk, closes the opening a', and shuts o the supply to the eduction-passage and basin. The upward movement of the valve-stem lifts the disk E from its seat, opening the port or passage e' for the water in the float-cham ber to discharge therefrom through the port into the ed uction chamber and passage to flow out therethrough to the basin, thus relieving the fioat-chamber of'the water and bringing the parts into position for the next operation of iushing, which operation is accomplished by again forcing down the val ve-stem to open and close the respective disks. The upward movement of the valve-stem carries with it the piston B', and such piston is forced against the water in the chamber of the casing B, the water furnishing a cushion to prevent any jar or concussion from the return of the stem and seating ofthe disk and allowing the disk to close gradually and only as the water escapes from the chamber surrounding the piston. As will be seen the main supply of water for flushing purposes also furnishesmeans for automatically operating the parts to shut off the supply through the medium of the float, and this automatic operation can be regulated as desired by simply adjusting the valvef to admit more or less water to the float-chamber, thereby regulating the period and the amount of water for flushing.

The knuckle-joint connection forms a lock for holding the main disk open until the Hushingis completed, which is determined by the release of the lock with the rise of the float. This lock instead of being of the construction shown in Figs. l to 3 can be of any suitable form of construction that will furnish a releasable lock by the rise of the float. A modied form of lock for this purpose is shown in Figs. 5 and 6, in which the lever H is forked and the float rests directly on the arms h of the fork. An eccentric or releasing cam J is mounted in the support or standard H and has secured to its pivotj` arms which extend out and are connected with pendants 9'2 from the bottom of the iioat. The rise of the float lifts the arms j and rocks or oscillates-the eccentric to engage the trip end i2 of the lever H and lift the knuckle-joint, so that it passes the center free to rise, as in the arrangement shown in Figs. l to 3.

Another form of lock connection is shown in Figs. 7 and 8. A pivoted latch or catch K is mounted on the upright or standard H' and is arranged to engage an arm KQ secured to the valve-stem. Thelatch has secured thereto arms la, which are connected with the bottom of the oat by links lo', so that with the upward movement of the oat the links and arms will turn the catch or latch K and disengage it from the arm K for the pressure of the supply on the disk D to operate the parts and close the disk D and open the disk E, as already described. It is to be understood that the tloat acts to resist the pressure of the main disk only to the extent that its weight serves to hold the knuckle-joint connection in line to prevent the upward movement of the valve stem and disk to close the induc- IOO IIC

tion port or passage. lts office is to furnish a means by which the pressure of the Water entering the float-chamber through the port fand acting on the bottom of the ioat will cause the float to rise and break the lock of the knuckle-joint, permitting the pressure to act on the valve-disk and close the induction port or passage. The float is not intended to open the valve against the pressure of water thereon, as such opening is from the lever I when forced downward, pushing the stem C downward or inward to open the disk D. The ioat never acts and could not act to open 'the main disk, as its only office is to retain the knuckle-joint in lock when the ioat is down and to release the knuckle-joint from its lock as the float rises.

The cushioning-piston and its chamber 'for holding the main disk against too-rapid return in closing instead of being located in the ind notion-passage of the main shell or casing could be otherwise located. A location for this chamber and its piston is shown in Figs. il and l0 as on the upper side of the main shell or casing and surrounded by the chamber of the iioat. ln this arrangementthe casing B is Jformed with the body of the main shell or casing, so as to inclose the cushion or liquid-pressure chamber B2, in which is located the piston B, attached to the reciprocat-ing stem.

The cushion-chamber has communication with the float-chamber by means of a passage or port l), and in communication with the discharge-port c, which in the construction shown is located in the bottom of the cushion-cham ber, is a chamber or passage c,which communicates with a discharge-pipe c', leading out through the ednction-passage.

The operation, so far as cushioning effect is concerned, is precisely the same as described for the same parts in the construction of Figs. l and 2, except that the wat-er to supply the resistance comes from the Heat-chamber and passes through the opening or port l) into the cushion or pressure chamber and thence up around the edge of the piston to lie above the piston and by its slow discharge hold the main disk against rapid and quick closing. The piston or cushion chamber in the construction of Figs. 9 and lO is open at the top and closed by a screw-threaded cap B3, through which the valve-stem passes. rlhis arrangement, it will be seen, leaves the induction-passage free from obstruction and so that the in flow ol;'\vate1\vill11ot be checked, and, as shown, the induction portion A3 of the main casing is a separate piece attached to the neck A" by means of a screw-threaded locking and retaining band a5.

The valve as a whole in either form of construction and arrangement is to be attached hereinbefore described, and its operation is in both cases the same so far as concerns controlling the inlet and outlet of the water for flushing purposes.

The principal advantages of my invention are that it eliminates the ordinary flushingtank, that it can be connected up to a direct water-pressure, that it is self-regulating as to the quantity of water admitted for flushing purposes after its first adjustment and use, and that it is always certain and noiseless in operation.

I claiml. The combination, in a flushing-valve, of a float-chamber, a valve-stem, a fioat encircling the valve-stem, a regulated water-supply for raising the `float, and a locking connection t'or the valve-stem released by the rise of the float from the inflow of Water, substantially as described.

2. The combination, in a flushing-valve, of a stem carrying a controlling-disk for the in duction water-passage, a lock for the stem, a neat-chamber, a rising and falling oat releasing the lock for the stem, and a regulated port supplying water to the float-chamber for raising the float to release the lock, substantially as described.

3. The combination, in a flushing-valve, of an eduction-compartment, a float-chamber, a regulating-valve between the eduction-compartment and the iioat-charnber and a iioat raised by a portion of the water diverted during the period of flush into the float-chamber for raising the float and permitting the shutting off of the intlow, substantially as described.

4. The combination, in a flushing-valve, of a Heat-chamber, a {ioat in the chamber, a diverted water-supply from the inliow entering the float-chamber and raising the float, and a lock for the controlling-disk of the infiow, released by the rise of the float and automatically stopping the inl-low of Water, substantially as described.

5. The combination, in a flushing-valve, of an eduction-chamber receiving a supply of water thereinto, a disk. controlling the watersupply, a float-chamber, a valve-controlled port leading from the eduction-chamber to the float-chamber, a Heat in the ioat-chamber, and a locking connection for the disk released bythe rise of the water against the iioat, substantially as described.

6. The combination of a main shell or casing having an induction-passage and an eduction-passage, a reciprocating stem, a disk carried by the stem opening and closing the induction-passage, a second disk carried by the stem, a float-chamber mounted on the main shell or casing and having a regulated supply froni the main supply and having a discharge controlled by the second disk of the stem, a float in the chamber, and a connection for the stem released by the rise ot' the float, substantially as described.
