Serial No- 138.642.

To a, whom it may concern;

Be it known that 1, JOHN N. SANGER, a citizen of the United States, and a resident of Brooklyn'Hills, borough of Queens, county of Queens, city and Stateof New York, have invented certain new and useful Improvements in Flushing Devices, of which the fol lowing is a specification.

My invention relatesto flushing devices, particularly such as are used in connection with water-closets; I

The object of my present invention is to provide an efficient, substantially-constructed, and readily-dismembered flushing device of that class in which the flow of the water is started by opening a controlling-valve andin which provision is made for a continued flow of water during a limited period of time following the closing of said valve for the purthe outlet-comp artment A which is separate pose of refilling the bowl of the water-closet after flushingit.

The invention will befully described hereinafter and the features of novelty pointed out in the appended claim.

Reference is to be'had to the accompanying drawings, in which Figure 1 is a central sectional elevation of one form of my improved flushing device, and Fig. 2 an inverted plan of the main valve.

The casing A, of substantially cylindrical shape, has an inlet A leading to the inletchamber A and an outlet A connected with Theinlet-chamber communicates with the opposite end of the casing through the medium of a channel A which at its upper end leads to a water receiving or com ression compartment A, from the inlet-chamb er A by a piston B This piston is connected, as by a rod 0, with the main valve controlling the connection of the inlet-chamber A with the outlet-compartment A. In detail, this valve has, a disk D, adapted to engage a seat A, located at the junction of the inlet chamber A with the outlet-compartment A, so that the seating of said disk will completely interrupt the direct flow of water from the inlet to the outlet. The valve is tween the inlet A inner surface of the outlet-compartment A. A cylindrical dportion F1 is preferably located between the isk D and the arms E. It will lye understoodv that the spaces between the arms will form ports for the passage of water as soon as the upper ends'of the arms are raised above the valvc seat A", and the area of these ports will increase as the valve rises and diminish as it falls, and this with articular rapidity if the arms E are taperet as described, so as toxincrcase the width of the ports, as well as their h oi ght, when the piston rises.

At. the orifice b ywhich the channel A com mu-m'cates with the receiving-compartment I prefer to locate the regulating-valve G, preferably in the nature of a needle-valve mounted to screw for adjustment. From a point of the receiving-compartment which is preferably in the same transverse plane with the upper end of the channel A and diametrically opposite thereto a controlling-channel A leads to the outlet-compartment A. At the upper end of this channel a seat A is formed in the receiving-compartment A for the controlling-valve H, which is located within said compartment, so that it would be in the path of the piston B if the travel of the said piston were not limited by a stop, as will be set forth presentl preferably arranged to c ose as by box J The valve H is I valve projects through the casing to the handle H.

The end of the casing adjacent to the receiving-compartment A is provided with a screw-cap K, which preferably carries a stop L, arranged to arrest the piston B before it collides with the valve H and before it. covers the upper orifice of the channel A. The stop is preferably adjustable relatively to the cap K, so that the travel of the piston maybe varied. As shown, the stop has a screw connection with the cap.

Fig. 1 illustrates the normal position of the parts when the valve-disk D and valve H are seated so that there is no communication beand the outlet A Water may, however, pass from the inlet A. to the receiving-compartment A through the channel A so that said compartment will be filled the valve II will close, so that the and the pistonB will be balanced, as the pressure will be the same on both of its "aces. Now when it is desired to produce a flushing action the controlling-valve II is pressed inward,-s 0 as to admit water from the receiving-compartment A through the channel A to the outlet-c )mpartment A and the outlet A Prior to this the inlet-chamber A has held the valve-disk D to its seat A. As soon, however, as communication is established from the receiving compartment A to the outlet the pressure in said compartment becomes less than that in the inlet-chamberA. New inasmuch as the piston B is of larger diameter than the elt'ective surface of the valve-disk I) the pressure on the lower surface of the piston becomes sutlicient to raise said piston,-and with it the valve-disk, so as to establish a communication from the inletchaml er A" to the outletcompartment A through the valve-scat A as soon as the cylindrical valve portion F rises above said seat. The upward movement of the piston is arrested bv the stop L. As soon as the lmobor handle II is released reduction of pressure due to the discharge through the channel A will cease. if an equal pressure were restored immediately on both sides of the piston l3, the valve-disk I) would be forced back on its seat almost instantly. This is prevented, however, and the seating of the valve-disk is retarded owing to the checking of the water-supply to the compartment A by the regulatingwalve G. In consequence thereolthc piston will move so as to and to allow of the seat the valve-dish slowl} The [low so-called after fill of the bowl.

of water through the valve-seat A will be.

diminished gradually owing to the progressive decrease in the size of the ports formed by the spaces between the arms i The decrease will be quicker if the arms E are tapered toward their free ends, as shown. The time required lor the sealing ol" the valvedisk 1) can be regulated by adjusting either thestop liorthe needle-valve G. This valve,

water-pressure in the l l l l however, is always open during operation of the flushing device.

If for any reason repairs should have to be made to any interior part, the needle-valve G will be closed and the cap K will be removed. As this relieves the pressure on the upper surface of the piston, the latter will be thrown upward, (even if the connection of the outlet A with the water-closet should be interrupted, as by turning a stop-cock,) and the piston, with the valve attached thereto, would be blown out through the top of the casing A if the valve H did not act as a stop under these circumstances. The valve will stop the piston before it covers the orifice of the channel A'*- adjacent to the needlevalve G, so that the operation of the last-named valve may be tested readil v.

hat I claim as new, and desire to secure by Letters Patent, is-

The combination, with the casing having an inlet-com n1rtment and an outlet-com the normal )artmcnt with a valve-seat between them of a valve arranged to close upon said seat, a piston connected with but distant from said valve and separating the inlet-eompartn'lent from a reeeiving-compartment, a channel connecting said receivirig-compartmentwith the i nlet-com partment, another channel connecting the receiving-compartmcnt with the outlet-compartment, a cap for closing the end of the receiving-ctnnpartment opposite to the piston, a stop carried by the cap and arranged to normally arrest the piston and a controlling-valve for normally closing the channel which connects the reeeiving-eompartment with theoutlet-compartment, said controlling-valve projecting into the receiving-compartment to serve as a stop for the piston when the cap is removed.
