T0 at! whom it may concern."
Be it known that 1, BERNARD H. llllOSSING Horn, a citizen of the United States, residing in the city 01 St. Louis, in the Eltate of ll/l1s souri, have invented a new and useful Flush Valve, of which the following is a specification.
This invention relates to improvements in flushing or similar tank valves, and pertains chiefly to that type of valvein which the water displacement oi the submerged valve member acts to operate the valve.
The object of my invention is to provide counterpressure means for thecval've member holding same raised when valve is open, thereby allowing a more substantial construction of the valve member than is usual in valves of this type; to provide means for diminishing said counterpressure when valve member is seated, allowing thereby a more secure closing of valve; to provide a weighted valve member and at the same timesuitable operating means, which through variation of the mechanical moments, iacilitates the raising of said valve member; and to provide a battling surface in connection with the valve mem er which serves to diminish a noisy closing motion of valve member, when falling through water.
Vllith the above and other objects in view 1 have invented the device illustrated in the accompanying drawings, in which:
Figure 1 shows the valve mounted in the closet tank and in open position, discharging water into the closet bowl. lhe dotted outmatically supplied with water by a ball cock (not shown). In the bottom of tank 1 is provided an orifice in which valve body 2 is firmly fastened by means of look-nut 3, the gasket 1 rendering the connection watertight. Internal to valve-body 2 extends the bracket 5 carrying the centrally disposed "eye 6, through which the guide stem 7 projecting below weighted valve-member 8, is vertically slidable, guiding valve-gasket 9 onto valve-seat 10, when valve is closing. Valve-member 8 has a lower portion wider than the valvegasket 9, furnishing the battling surfaces 11, which while passing downward through the water remaining in the tank at the close of discharge, tends to retard the falling motion of valve-meinber 8, thereby precluding a noisy closing of valve. Valvegasket 9 is held to valve member by plate 12, which in turn is held firmly in place by the nut 13, screwed onto the lower projection 14: of valve-member 8, A continuation 15 extends upward from valve-member 8, whidh is connected by means of rod 16 to the arm 17 of balance lever 18, which balance lever is pivoted by means of pin 19, mounted into the extremity 20 of overflow tube 21, connecting with the port 22 emptying into the outlet orifice beneath the valve-seat. Lever 18 has another arm 23, forming an angle with atorementionedv arm 17 thereby giving lever 12 the character and properties of a so-called bent-lever. Said arm 23 is weighted by means of weight 2 1, the line of gravity of which weight moves toward and away from the pivot pin 19 Tv ith the corresponding movement of lever 18, varying as a consequence its counterbalancing' influence upon valve-member 8. Extending downward from lever 18 -'s the projection 25, serving as stop checking motion of lever when valve is completely open. Another stop 26 projects from lever 18, and serves to check downward motion of 18? arm 17.
The mechanical moments of bone lever 18 together with. weight 2 1 and valve-member 8 are proportioned so that said weight 2 1 outbalances said valvememher and attach nients when the water displaced by said valve-member tends to buoy same up, under which conditions valve-member would remain in raised. position, after it has been given such position by suitable operating means. As soon, however, as the lowering water lev el diirii'nishes eaid water displace ine'ntthe added weight on arm 17 will outmounted revolubly in the bushing 28 fastened firmly to the tank by means of nut 29. Inside of the tank and firmly fastened to handle 27 is the lever arm 30, the extremity of which is connected with balance lever 18 by means of a series of links 31, or the like. Turning the manipulating handle 27 on its pivot turns the lever arm 30, which in turn exerts a pull on connecting means 31, pull- 0 ing the weighted arm 23 to the left, thereby raising valve member, opening valve. After the handle 27 has again been freed, it tends by means of its own gravit to resume the position as shown. It wil be noted that the leverage proportions and relative arrangements shown tend to efi'ect easy operation of valve, the manipulating handle 27 traversin a greater are in relation to the length 0% stroke or lift of valve-member, during the period when counterbalance weight 24: exerts less influence upon valve member 8. 32 is an orifice or overflow edge, formed by cutting out a piece of overflow tube atits upper extremity and serves 25 the purpose of limiting the maximum water level, such as may be attained through leak in ball-cock, so that the pivot pin and lever mountings should not be corroded or afiected by contact with the water of the tank.
The term bent-lever, as used throughout thesespecifications and claims is to be interpreted in the-technical sense, as denoting a triangular relation between the three lever factors of weight, power and ful- 5 crum, irrespective of the shape of the material actuallyto be used in constructing same. Having thus described my invention, that i which I claim to be new and'desire to be protected by Letters Patent is:
1. A valve seat, a bent lever one arm of which is weighted and the other arm of which carries a non-fioatable valve member adapted to rest on said valve-seat, which bent lever is mounted and movable on its fulcrum in such a manner, that the force pressingsaid valve member downward toward said valve-seat, which force is equivalent to the moment of the resultant of all of the gravity forces afiecting said lever, gradually decreases with the gradual valvemember-raising movement of said lever, and means raising said valve-member, the decrease in the buoyancy of said valve-memher, due to the decrease of its submergence at the recession of the water level, closing the valve.
2. A valve seat, a valve member, means pressing said valve member to said seat, means raising said valve member, and
so means gradually counteracting and reducing said pressure means when the valve memher is thus being raised, the buoyancy of said valve-member when submerged together with the counter-acting means holding said valve member raised.
3. A valve seat, a valve member, a bent lever to one arm of which said valve member is connected and the other arm of which is weighted, which lever is mounted on its fulcrum in $1101 a manner that said weighted arm approximately counterbalances the other arm with the connected valvemember, when the valve member is in its raised position, which counterbalance efi'ect decreases with the closing motion of said valve member, and means actuating the valve.
4:. A valve seat, a valve member, a fulcrumed bent lever to one arm of which said valve member is connected and the other arm of which is weighted to approximately counterbalance said valve member when the valve is open, the vertical line passing through the center of gravity of which weighted arm gradually approaches the fu lcrum point when said valve member is lowered to its seat, thus diminishing its resistance to the gravity of said valve member when the valve is closed.
5. A valve seat, a weighted valve member,
pressure means opposing the gravity of said weighted valve member, which pressure is variable so that it gradually increases with the gradual opening of the valve, and operating means raising said valve member and constructed to have greatest leverage ratio thereto at the beginning of said valve opening, which ratio gradually decreases with the gradual raising of said valve member.
6.'A valve seat, a valve member having means displacing water, thereby tending to buoy up said valve member when submerged, and variable pressure means opposing the gravity of said valve member, which opposition gradually increases with the gradual raising of said valve member and holds said submerged valve member raised when the valve is completely open, the aforesaid pressure means bein overcome by the weight of said valve mom or and its attachments when the water level recedes sufii ciently to diminish the aforesaid water displacement, thus closing the valve.
7. A valve seat, a valve member having means displacing water thus tending to buoy up said valve member when submerged, a bent lever to one arm of which said valve member is'connected, and the other arm of which is weighted and outbalances said submerged valve-member when completely raised, and means raising said valve member, the weight of said valve member and its attachments when the water recedes diminishing the aforesaid displacement c 1.; the valve.
8. In a tank, a valve seat, a valve meml being weighted so as to be pressed onto saio valve seat effecting a secure closing of the valve, and being adapted to displace water, thereby tending to be buoyed up when sub- MEBEWMM merged, and variable pressure means opposing the gravity of said valve member, which opposition gradually increases with the gradual raising of said valve member and holds said submerged valve member raised when the valve is cempletely open, the aforesaid opposition being overcome by the Weight of said valve member and its attachmeets when the Water level recedes eufi ciently to diminish theaforesaid Walker disre placement, thus closing the valve.
