" T ai'lwlzom it may concern:

' Be it known that I, DANIEL 'W. MGNEIL, a citizen of the United States of America, and resident of Cincinnati, county of Hamilton, and State of Ohio, have invented certain new and useful Improvements in Flush Mechanism for Closets, of which the fol lowing is a specification.

This invention relates to flush mechanism for closets, and has for an object to produce a s'simple and reliable seat actuated flush valve and valve operating mechanisms of plication and forming improved construction. This and other objects I'attain by means of apparatus embodying the features herein described and illustrated.

In the drawings accompanying this apa part-thereof, Fig. 1. is an elevation of a closet embodying my invention, portions being shown in section and portions being broken away for convenience of illustration. Fig. 2 is a sectional view of a portion of the valve operating mechanism, which forms a part of my invention; Fig, L is a sectional view of an improved form of flush valve which forms a detail of my invention.

Referring to the drawings :-The apparatus illustrated, comprises a ball-float or flush valve 1, which is located in a flush tank 5, a seat operated mechanism for unseating the Valve 4, and a stop valve 6 which is actuated by the seat operated mechanism, and is adapted to shut off the flow, of water from the tank 5 while the operating pressure is maintained on the seat 7 and while the valve is open or unseated. The flush valve 4 illustrated consists of a hollowballshaped disk, which is preferably made of rubber and 1s provided on one s1de with a lug 8, 1n which a metal ferrule 9 is located.

,Th'eferrule is'provided with a threaded and I longitudinally extending opening, which registers with apertures provided 1n the lug 8. A stem or guide rod 10 for the ball 4 is threaded at its lower. end and is adapted to be screwed into, the ferrule 9. A contact rod 11 is threaded at its upper end and is screwed into the lower end of the ferrule 9.

This rod extends from the ferrule down= wardly through .the interior of the .ball' 1 and projects a short distance beyond the surface of the ball through an aperture 12. The stem or guide rodlO is secured in place in the tank 5 in any suitable manner, so that it will permit the ball to move up and down freely, but will to some extent guide its movements. The ball 4 is adapted to seat on a flange of a discharge port 13, provided in the bottom of the tank 5, and in this manner cut off communication between the tank 5 and a flush pipe 14, which extends downwardly from the port 13 and communicates with the flush passages of the porcelain bowl 15 of the closet.

A release rod 16 extends ,u,pwardly through the piping let; and is provided at its upper end with a' cup-shaped seat '17, which is adapted to contact with the contact rod 11 of the ball 4 and to raise'the ball-from its seat, for the purpose 'of opening the port 13.

The ball 4 is held to its seatby the unbalanced water pressure, but as soonas it is unseated, it is exposed on all sides to water pressure, and consequently floats upwardly and fully opens-the port 13. The. ball will not close the port until almost all of the water is discharged from the tankand the ball has moved adjacent to the port 13. It is then carried by the flow of water, through the port, to its seat and the unbalanced condition is reestablished. The release rod '16 extends downwardly through the piping 14: and its lower end seats on the valve 6, which is located in a housing 18, secured to'the lower end of the piping 14. The housing 18 is provided with a; discharge port 19, which communicates through suitable piping 20 with the flush passages of the bowl 15. The valve 6 is mounted on a rod 21 and is adapted to'seat on an annular flange or seat 22, provided on the housing 18, for the purpose of closing communication between the piping 14 and the housing 18, and consequently between the flush tank 5 and the flush passages of the bowl 15. The lower end of the housing 118 is closed by-a'screwcap 23, through which the rod 21 projects, and which is provided withan integrally formed annular flange 24:, in which a suitable packing 24' for the rod 21 is located.-

.A- depending sleeve 25. is screwed, or otherwise secured, to the flange 24 and forms a guide for a cap-nut 26, which is screwed this arrangement, the packing 24: is maintained tight by the tension of the spring 27, and the bushlng 28 forms a guide for the rod 21.' The cap-nut 26 is adapted to contact with the lever 29. ,A disk 32 is secured on the rod 21 and is so located within the housing 18, that it will seat on a flange pro vided on the cap 23 around the rod 21, when the rod is moved to its lowest position by the tension of the spring 27.

The valve 6 illustrated, consists ofa valve I disk providedv with means for securing a washer in-place, and provided with an annular flange 33, whichis adapted to fit over '0! cap the upper end of the-rod 21, and is secured in place on the rod by means of what may be termed a lost-motion connection. The lost-motion connection consists of a pin 34:, which extends diametrically across the flange 33 and is located within a longitudinally extending slot 35, provided in the rod 21 near its-upper end. The valve 6 is yieldingly held inposition on the rod 21 by a coil spring 36, which surrounds the upper end of the rod and the flange 33 and yieldingly forces the valve upwardly, so that the pin 34= is normally held'in contact with the upper end of the slot 35 With this arrangement, the lost-motion connection is self-adjusting. a

The operation of the ap aratus is as follows: When the seat- 7 is epressed against the bowl 153, the rod 21 is raised through the agency of'the lever 29, so that it moves the valve. 6 against its seat 22 and causes the release rod 16 to move upwardly andunseat' the valve 4. This opens communication between the tank 5 and the flush pipe, 14, but does not permit of a flow of water to the'bowl 1 5, since the valve 6 closes communication between the piping 14 and the housing 18. As soon as the depressing force is removed from the seat 7, the rod 21 is forced downwardly by the pressure of the s rin 27, so thatjthe va1ve.6 is unseated, t e (1151; 32 seated, and so that the seat 7 is raised to the normal or inoperative position. The 'unseating of the valve 6 opens communication between the tank- 5 and the bowl 15 and causes a flow of water from the tank through the flush passages of the bo'w1.

Byemploying. the self-adjusting lost-motion connectlon-between the valve 6 and the rod 21, the rod 21 may be raised a considering leakage around the rod and is eifective when the rod 2]. is forced to its lowest position. The washers on the valve 6 and on the valve disk 32 may be renewed by simply removing the cap 23 and withdrawing the-valve from the housing 18. The tension of a fixture '38; With this arrangement, the

flush pipe 4 andtthe'housing 18 are rendered more rigid and the housing is prevented from turning out of alinement after the closet is installed.
