To all whom it may concern: 1 v i 1 Be it known that I, CHARLES W. DARROW,

of Glenwood Springs, in the county .ofGarfield and State of certain new and useful Improvements in Flushing Devices; and I do hereby declare the following to be a'full, clear, and exact de scription of the invention, such as will en able others skilled in the art to which it ap pertains tomake and use the same.

The primary object of this invention is to produce an extremely simple and inexpensive flushing device, which will be free from noise, capable of being started and stopped without-shock or wire drawing, and which will be composed of but few parts. V

In the accompanying drawings, Figure 1 is a longitudinal sectional view. Fig. 2 is an end view, partly in section, showing the control valve in the position it occupies when the main valveis seated. Fig. 8 is a view somewhat similar to Fig. 2, showing the control-valve moved to allow the main valve to be unseated. 1

Referring to the drawings, 1 designates a casing; 2 the inlet; 3 the outlet; and 4 a bypass leading from the inlet to the pressure chamber of the casing. Communication between. inlet 2 and outlet 3 is controlled by a main valve 5, which is shown as having a cylindrical body portion fitting within the pressure chamber, and as having a tapered portion 6 which, when it engages its two seats, will cut off thefiow of Water,'said tapered portion 6 terminating in a lug 7, as'located centrally of lVhen the valve is opened of this lug is within the end of the inlet opening the inlet opening. the lower portion plane of the upper so that the outflow causing a damming of the water at this point and a'consequent greater force or pressure through the bypass to the upper side of the valve, thus insuring closing of the valve against the inlet pressure. This valve 5 is free to turn on its axis while moving longitudinally toward and away from its seats.

The entrance of the water through bypass 4 into the pressure chamber is controlled by a swinging valve 8, which is pivoted at the axis of casing 1 on a stud 9 extended through end cap 10, an operating handle 12 being secured to said stud. I have shown packing 13 surrounding the inner end of the stud and bearing against'the face of rnusnnve nnvicn.

cap-10. The valve Sis preferably in the formiof-a sector,,and isfprovided with an a-rcual slot 14 so as to form a spring arm carrying valve face 15, which is designed to cut off the entrance of water from the bypass to the pressure chamber. This valve 8 has a radial face which carries from the pressure chamber whenthe by-pass is open, xandafor opening such outlet when the by-pass is closed. I have shown the outlet from the water' chamber as consisting of a pipelF, held in place by a plug and which may be connected to the bowl.

' As shown in Fig. 2, when valve 8 is moved to uncover the by-pass, the outlet through pipe 17 is closed by the radial portion of the valve. lWhen the latter is in this position pressure will build up and effect the seating of the main valve against the incomlVh'en the control valve is moved into the position shown in Fig. 3, the by-pass is cut off, and the pressureis relieved by uncovering pipe 17, permitting the main valve to be automatically unseated. Normally, the operating handle 12 occupies a horizontal position, as indicated in Fig. 2. When raised to permit the operation of the fiusher, it will.

promptly return to its normal position by gravity, and in so doing will move the control valve to close the outlet from the pressure chamber, and open the inlet thereto through the by-pass. l/Vithin the by-pass 4c I locate a cook 20 by adjusting which the quantity of water allowed to flow through the bypass for seating the main valve may be controlled. and by reason thereof also the time required for the main valve to return to its seat.

The advantages of my invention will be apparent to those skilled in the art. It will be noted that in my present flushing device the use of springs is unnecessary; that the device is composed of comparatively few parts, and hence not liable to readily get out of order; it will close without jar or shock; is noiseless in operation; and the main valve being free to turn on its own axis will wear longer than one moving on fixed lines, and having a double seat the wear is reduced onehalf of what it would be with but a single seat. a

I claim as my invention:

1. A flushing device comprising a casing having an inlet, an outlet, a pressure cham- Patented Aug. 18, 1914.

adisk 16' of anysmtable material for closing the outlet ber, chamber with the inlet side of the casing, a main valve fitted in said chamber and designed to cut off communication between the inlet and outlet, said valve having a centrally extended lug which is designed to fit in said inlet to restrict-the outflow when the valve is opened, said pressure chamber having a relief outlet on the same plane as, but away from the entrance of, said by-pass into said pressure chamber, a disk-like rotary valve having port controlling faces in parallelism with the axis of said valve for normally closing the outlet of the pressure chamber and opening communication between the latter and said by-pass, and an operating handle for rotating said valve to uncover said latter outlet and close communication with said by-pass.

2. A flushing device comprising a casing having an inlet, an outlet, a pressure cham ber, and a by-pass connecting said pressure chamber withthe inlet side of the casing, a main valve fitted in said chamber, and designed to' cut off communication between the inlet and outlet, said pressure chamber having a relief outlet, a rotary valve having a spring arm for closing said by-pass, and also having a radial portion for closing the outlet from the pressure chamber, which outlet is at right angles to the pressure chamber, and

and a by-pass connecting said pressure an operating handle for moving said control valve. v

3. A flushing devicecomprising a casing having an inlet, an outlet, a pressure chamber, and a bypass connecting said pressure chamber with the inlet side of the easing, said pressure chamber having an outlet, a main valve of cylindrical formation capable of moving longitudinally in said pressure chamber and having a reduced portion,

said valve being capable of turning on its 7 axis, a control valve in the form of a sector having two port-controlling faces, one face controlling said by-pass, and the other the outlet from the pressure chamber.

4:. In a flushing device having a pressure chamber, a port leading into said pressure chamber, and an outlet pipe leading from the pressure chamber at right angles thereto,

a valve in the form of a sector having a spring arm, the end of which is designed to extend over said by-pass, said valve also having a radial face for closing said outlet pipe.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
