FLUSHING APPARAT'US.

Speciflcation of Letters Patent.

Application filed August 24, 1907.

Patentcd May 3, 1910.

Serial No. :389,934.

To all whom tt may concem:

Be it known that I, PAUL S. MILLICE, a citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Flushing Apparatus, of which the following is a speeification.

My invention relates primarily to that character of flushing apparatus intended for use in connection with water closets, and has for its object the providing of flushing means whereby the fiushing may be accomplished by direct flow from the water service, such as a city or other public service, under the direct pressure of said service.

My present invention is an improvement on the flushing apparatus shown described and claimed in my application tor Letters Patent of the United States, filed August 3, 1906, Serial No. 329056.

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a side elevation of my improved deviee shown connected up and aplied to a water closet bowl. Fig. 2 is a ront elevation of my improved device. Fig. 3 is a rear elevation of the same with the Operating hanclle partly broken away. Fig. 4 is a central vertical longitudinal section of my improved device,.shown on the line w-x of Fig. 2, partly broken away. Fig. 5 is a plan vew of my improved device and, Fig. 6 is a bottom view of the same.

1 represents a closet. bowl, with which my improved device is adapted to be connected by a suitable coupling 2.

3 represents a casing in which there is a fluid passage 4 with which a chamber 5 has connection through a port 6, the chamber having communication with the water service, as by means of a supply pipe 7, the pipe being threaded into an opening 8 of sub stantially greater diameter than the port 6. This permits a supply pipe having a bore 9 of greater cross-section than the port 6 to be employed for the purpose of providing an infiow through the opening 8 of greater Volume than the capacity of the port 6 for forming a back pressure in the supply-chamber 5 the port 6 forming the discharge opena pressure-compartment 10 from which a port 11 communicates with the fluid passage there being howcver, a web 12 in the fluid passage for forming a cavity 13, whose mouth 14 opens into the fluid passage in the direction of flow of water through the fluid passage, as indicated by the arrow a. The web 12, cavity 13 and mouth 14 are preferably located within the longitudinal projections of the walls of said fluid-passage at the discharge-end of the same. At the port 11 there is a valve seat 15 for accommodating a valve 16 on a valve stern 17 operated in suitable manner, as by means of the lever 18 having the pivot 19 on the lug 20, and having a screw 21 pass through a slot 22 in the upper end of the stern.

24 is a compression hearing for the valve stern. This hearing is threaded into a thrcaded opening 25 in the casing of larger diameter than the valve-seat 15. A spring 26 is interposed between the hearing and a collar 27 on the valve stem for normally causing seating of the valve 16.

31 is a valve-shell Secured in a threaded opening 32 in the wall 33 of the casing, which wall separates the pressure-Compartnent from the fluid passage. The shell accomnodates a compound valve 34 which is preferably a triple valve, comprsing the valves 35 36 37. The compound valve has a stern 38 adapted to reciprocate in the bearing 39 in the shell. The valves 35 36 37 are respectively adapted to seat against the valve seats 40 41 42, respectively at the port 6, at the hearing 39 and at the larger end of said shell. The valve 37 preferably takes the form of a flap-valve or thin disk of flexible rubber or leather or other suitable substances Secured to the outer end of the hub 43 of the compound valve by means of a Washer 44 and screw 45. The valves 35 36 are preferably compression valves in the form of disks of rubber, leather or the like. They are held in place by providing the valve-stern with a reduced end 46 about which the disks 35 and 36 are received at the respective sides of a collar 47, a Washer 48 and screw 49 securing the parts in place. The body of the shell serves as a bearing for the hub 43 of the compound valve. This hub is of greater diameter than the port 6, that is ing or said chamber. The casing also has i to say, the opening of the valve seat 42 is a threaded cap 51. There is a passage 55 in said casng between the chamber 5 and the pressure-compartment, forming a bypass around the compound valve. 56 is a plug threaded into said passage and held in place by a lock-nut 57 the said plug having a head 58 for turning the same., This plug has a valve seat 59 theren adapted to be engaged by a valve 60, shown as a needle valve on a threaded stem 6l threaded into the plug 56, a lock-nut 62 serving to lock the stern in place in the plug. These lock-nuts 57 62 also serve to prevent leakage. The plug is provided with a port 63 which communicates with the bore 64 of the plug so that the fluid may pass from the chamber 5 through the port 63, bore 64, valve seat 59, and by-pass 55 into the pressure-compartment.

It will be noted that the diameter of the opening in the valve seat 59 is of substantially less cross-section than the port 6, the supply opening into chamber 5 in turn being preferably greater than said port 6. If now the valve 16 be raised, the pressure in the pressure-compartnent is relieved and the fluid in the pressure-compartnent will be received by the fluid passage. As soon as the pressure in the pressure-compartment is relieved, the compound valve 34: will unseat from the seat tofor permitting flow through the port 6. The pressure from this port will force the compound valve away from said port for causing the valve 36 to seat against the-valve seat 51 for preventing leakage around the compound valve from the fluid passage into the pressure compartment, the valve 16 having meanwhile been closed, and compelling the filling of the pressure-compartment to be accomplshed through the bypass, so that the moment of shutting ofl ot the flushing may be definitely determined. The 'supply water takes the course of the arrow a into the bowl, the web 12 protecting the flow from the pressure-compartment through the port ll for preventing shutting ofl' of that flow while the valve 16 is open. The supply opening being greater than the port 6 will cause part of the fluid to pass through the valve seat 59 and by-pass 55 into' the pressure-compartment. This opening in the valve seat 59 is comparatively small so that greater pressure will result in the pressure compartrnent, which will be eXerted upon the top of the compound valve for causing the valves 35 37 to be seated when the pressure in said pressure-Compartment has overcome the pressure of the flow through the port G against the bottom of said valve, this seating being accomplshed with comparative rapidity.

My improved device is simple 'in Construction and practically noiseless in operation.

Having thus fully described my invention what I claim as new and desire to secure by i Letters Patent is:
