FLUSHING APPARATUS AND VALVE MECHANISHE THEREFOR.

Specification of Letters Patent.

Patented Oct. 30, 1917.

Application filed March 17,1917. Serial No. 155,382.

To all whom it may concern:

Be it known that I, HARRY G. TRAVER, a

citizen of the United States, and resident of tidgewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Flushing Apparatus and Valve Mechanism Therefor, of which the following is a specification This invent-ion relates to water flushing apparatus particularly adapted for flushing toilet bowls, urinals and the like in which the water for flushing purposes is under abnormal air pressureor greater'than ordinary atmospheric pressure, and it is the primary object of the invention to improve and simplify the general construction of flushing apparatus of this character to cheapen the cost of manufacture and at the same time increase the eficiency thereof.

It is a further object of the invention to provide a flushing apparatus in which manually operable means is provided to perform the initial functionof seating a valve to release the and in which the incoming water to the reservoir operates to open the valve as it is unseated and with the pressure of the water in the reservoir during the flushing operation maintains the valve open, said incoming water also operating to close the valve after the flushing operation and with the pressure of the water in the reservoir maintain the valve closed.

Another object of the invention relates to improved-valve mechanism to control the flow of water from the reservoir and to improved means toactuate the valve.

lVith the foregoing objects and other objects and advantages hereinafter set forth I have shown in the drawing in side elevation, partly in section, a flushing apparatus illustrating an embodiment of my invention.

The embodiment of my invention shown in the drawing comprises an air tight water reservoir or tank 1, only a portion of said reservoir being shown, from the lower portion of which the water is discharged, as through an opening :2 at the bottom connected'to a closet bowl 3 through a pipe 4 connected at one end to the opening in the reservoir and at the other end to theinlet of a valve chamber 5, and a pipe 6 connected at opening or unflushing water,

one end to the outlet of the valve chamber and at the opposite end to the closet bowl 3. The flow of water from the reservoir is controlled by valve mechanism comprising the chamber 5 and opening lnto the valve chamber, or having a gravity seating valve a closing movement toward and an opening movement away from the outlet of the valve chamber. This valve is in the nature of a flap valve comprising a disk 7 having a stem to engage in an opening in a carrier of slightly larger diameter than the stem by a nut threaded onto the stem whereby the disk may have rotative movement and a slight lateral movement relative to the axis of the stem to permit of the ready seating of the valve. The carrier is pivotally supported at the top of the valve chamber, as at 8, to swing. on a. horizontal axis. The valve is adapted to cooperate with an annular valve seat 9 at the outlet of the valve chamber, this seat extending in a direction flightly inclined to the perpendicular there- )3 Access may be .had to the valve chamber through anopening closed by a removable plug 10. r

The connection of the water pipe 4 with the valve chamber connection 1s such as facilitating the seating of the valve disk. 7

to lead the water into the valve chamber bei low the valve opposite the pivotal support of the valve and direct the water in a vertical direction transverse to the valve seat and the opening valve to intersect the path of movement of the valve, for which purpose the pipe 4 is substantially of U-shape as shown. The water inlet connection of the reservoir 1 with a water main'is also through the pipe 4 and .the opening 2 by a water inlet pipe 11 of less diameter than the pipe 4 and is connected to the pipe 4 adjacent the connection of the pipe 4 with the valve chamber for a purpose to be hereinafter described. To drain the entire water or any sediment from the reservoir and valve chamber there is provided in the pipe 4, preferably in the bend thereof, a drain cock 12. This cock may and closing movements of the also be utilized to admit fresh air into the opening in the wall of the valve chamber maintain the valve in and a stuffing box 14, and is reciprocable in a direction in line with the valve. T he inner end of. the plunger is preferably rounded and adapted to engage with an abutment or boss 15 connected to or integral with the valve disk 7, the outer snr ace of said abutment preferably being rounded to receive the shocks and wear of the plunger and protect the ground face adjacent to the periphery of the valve disk 7. The plunger is manually operable from the exterior of the valve chamber to unseat the valve by a hand lever pivotally supported at l6'having a pin and slot connection 1'? with the plunger, and having a weighted hand grip 18 whereby when the lever is manually operated to impart movement to the plunger in one direction or into the valve chamber to unseat the valve and as it is released the weighted end of the lever will drop by gravity and automatically impart return movement to the plunger. 7

In operation the water from the main enters the reservoir compressing the air therein until the air is compressed to a point when the air pressure on the water is equal to and will overcome the pressure of the water entering from the main through the pipe ll. To perform the operation of flushing the handle is lifted thereby moving too plunger into the valve chamber, the epd of the plunger engaging the abutment lo and moving the valve plate 7 from its seat. As soon as the valve is unseated the water in pipe at due to the pressure of the air in the reservoir 1 and the pressure of the water in the inlet pipe 11 will be forcibly directed in a vertical direction into the valve chamber to intersect the path of movement of the valve and will impinge against the outer face of the valve. or the side of the valve toward the outlet of the valve chamber. operating to lift the valve to the dotted line position adjacent the top of the valve chamber and so long as the pressure of the water from the reservoir and through the inlet pipe ll is sufficient to maintain the valve in its raised position. As soon as the air pressure in the reservoir is reduced whereby the pressure of the water on the valve is not sutlicient to its raised position the valve will drop by gravity and as the valve begins to drop the pressure of the flow of water through pipe '11 will be directed against the inner or rear face of the valve and operate to firmly seat the valve, and the valve will be maintained seated by, the increasing pressure of the water flowing into the reservoir. After inward movement has been imparted to the plunger to unseat the valve the plunger operating lever is released when it will immediately drop and return the plunger to initial position.

While the pressure or the incoming water ismaintained in such position ing through pipe 11 for flushing purposes,

thepressure of such water through pipe 11 must not be so great as to o ercome the weight of the valve 7 and thereby prevent said alve from falling to its seat. I therefore provide avalve (shown in a general way at 19) to control the flow and regulate the pressure of the water through said pipe 11.
