RICHARD R. MITCHELL, OF MONTREAL, CANADA.
FLUSHlNG-VALVE.
SPECIFICATION forming part of Letters Patent No. 592,810, dated November 2,1897. Application filed February 26, 1897. Serial No. 625,147. (No model.)
To aZZ whom it may concern.-
Be it known that I, RICHARD H. MITCHELL, a subject of the Queen of Great Britain, residing at Montreal, in the Province of Quebec and Dominion of Oanada,have invented a new and useful Flushing-Valve, of which the following is a specification.
This invention relates to flushing-valves for use in connection with flushing cisterns or tanks for closets and the like; and it has for its object to provide a new and useful valve of this character having simple and efficient means for insuring a positive seating of the cut-off valve and means to prevent an overflow of the cistern or tank, as well as to provide for a proper venting of the device to obviate hammering'or chattering of the cut-0E valve in closing.
The invention also contemplates novel means for raising the cut-off valve from its seat to discharge the flush-water from the cistern or tank.
WVith these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.
In the drawings, Figure 1 is a vertical sectional view of a flushing-valve constructed in accordance with this invention shown fitted to a flushing cistern or tank. Fig. 2 is an en-' larged vertical sectional view of the combined float and vent device at the upper end of the overflow-pipe. Fig. 3 is a cross-sectional view on the line 3 3 of Fig. 1.
Referring to the accompanying drawings, 1 designates the valve-head casting of a valve, which valve-head is formed with a lower exteriorly-threaded discharge-neck 2, fitted in the bottom opening 3 of an ordinary fiushing cistern or tank 4 and having suitably coupled thereto, below the cistern or tank, the usual flushing-pipe 5, which leads to the closet or other place to be flushed.
At its upper end the valve-head 1 is formed with a valve-seat opening 6 directly in line with the discharge-neck 2 of the head and adapted to have seated therein the hollow air or cork filled ball-valve 7, preferably formed of rubber or other elastic material and of a sufticiently larger size than the valve-seat ment of a hinged lifting-frame 8, arranged to work at the upper side of the valve-head castin g 1. The hinged lifting-frame Sis provided with a valve-ring 9, which is of a materially greater diameter than the valve-seat opening 6, but is of a less diameter than that of the spherical cut-'ofi valve 7, so that in its normal position the valve-ring 9 rests flat on top of the valve-head 1, concentric with the opening 6 thereof, entirely out of contact with the valve 7, so as not to interfere with the free seating of the valve. The lifting-frame 8 has extended from one side of its valve-ring 9 an inclined yoke-arm 10, provided at its outer end with a pintle 11, that is loosely mounted in the bearing-eye 12, formed atone end of a short supporting-arm 13, projecting integrally from the valve-head at one side thereof to pro vide for the hinge-support of the liftingframe.
At the side of the ring 9 opposite the yokearm 10 the lifting-frame is provided with a short pull-arm 14, slotted at 15, to loosely work over the guide-arm 16, projected integrally from the valve-head 1 at one side of its valveseat opening and disposed in an upward di- 7 rection, the upper end of said guide-arm 16 having detachably fitted therein a stop-pin 17, which serves to limit the upward movement of the lifting-frame when unseating the valve. The ring portion 9 of the liftingframe has fitted thereto the lower ends of a pair of inverted- U shaped crossed cage-wires 18, which extend a distance above the liftingframe to form a valve-cage for loosely retaining the Valve 7 therein when unseated and also serving to hold the said valve in proper position for being guided to its seat as the level of the water lowers in the cistern or tank. A chain 19 is connected at its lower end with the arm 14 0f the lifting-frame and at its upper end with the .0perating-lever.19 fulcrumed at the top edge of the cistern or tank and having the usual pull-chain connection therewith at its outer extremity.
The valve-head 1 has formed integrally therewith a lateral hollow extension 20, which extension is projected laterally from one side of the head in a plane directly below the valve-seat opening 6 and in its upper side at one side of the plane of the opening 6. The lateral hollow extension 20 has formed therein an opening 21, in which opening 21 is fitted the lower end of a vertical overflow-pipe 22, at the upper end of which pipe is arranged to work a hollow overflow float-valve 23. The hollow overflow float-valve 23 has fitted to its lower side a sleeve 24:, loosely working on the upper end of the pipe 22 and provided in its side with a plurality of overflow-ports 25, through one of which ports projects a stop pin 26, extended from one side of the pipe 22 to limit the upward movement of the float 23 and prevent the displacement thereof. A valve-disk 27 is fitted within the upper end of the sleeve 24, and under normal conditions is seated on the top edge of the pipe 22 to prevent the metallic noise due to the metals coming together, and the said float 23, carrying the valve-disk in the sleeve 24, has fitted therein a smaller vertical vent-tube 28, extending at its opposite ends, respectively, above and below said float and providing direct communication between the outer air and the interior of the pipe 22 even when the float-valve is seated on the upper end of the said pipe. In the event of the water rising in the cistern or tank to an abnormal level the float 23 rises and carries the valve-disk 27 therewith. At the same time the ports 25 become uncovered and allow the surplus water to drain through the pipe 22 and out through the valve-head into the flushing-pipe 5; but normally the float-valve is seated on top of the pipe 22.
To drain the flush-water from the cistern or tank into the flushing-pipe, the pull eonnections are operated to elevate the frame 8, which IHOVGDIGII'G elevates the valve 7 from its seat, thereby uncovering the valve-seat opening 6 and permitting the flush-water to rush through the valve-head into the flushing-pipe. As the level of the water lowers in the cistern or tank the ball cut-off valve 7 will approach its seat and will become firmly seated to cover the opening 6 before the level of the water reaches the plane of such opening, as will be obvious, and at this point it will be observed that by reason of providing constant communication between the interior of the valve-head and the outer air through the medium of the Vent-tube 28 the air which enters such vent-tube will clear the full pipe below the valve of the weight of the water therein, thereby preventing the valve taking its seat so heavily as to rebound and cause a constant hammering or chattering, as is well understood.
Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in- Vention.
Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-
1. In a flushing-valve, a valve-head provided with a pendentdischarge-neck, a valveseat opening at the upper end of said neck, an upwardly-disposed guide arranged at one side of the valve-seat opening and having a stop at its upper end, and a short supportingarm at the opposite side of the valve-seat opening and having a bearing-eye, a ballvalve arranged above the valve-seat opening, an integrally-formed lifting-frame having a ring portion arranged concentric with the valve-seat opening and of a less diameter than the ball-valve, and oppositely-located arms, one of said arms being hinged in the eye of the supportingarm of the valve-head, and the other of said arms loosely working over said guide, and avalve-cage rigidly fitted to the lifting-frame and extended above the ring portion tlieieofisubstantially as set forth.
2. In a flushing-valve, a valve-head provided with a pendent discharge-neck and a valve-seat opening at the upper end of said neck, a hollow ball-valve arranged above the valve-seat opening, an integrally-formed lifting-frame hinged at one end to the valve head and provided intermediate its ends with a ring portion arranged concentric with the valve-seat opening and of a less diameter than the ball-valve, said lifting-frame normally lying directly on top of the valve-head and having an operating connection with its unhinged extremity, and a valve-cage extended above and rigidly secured to the ring portion of the lifting-frame, substantially as set forth.
3. In a flushing-valve, a valve-head formed in its upper side with a valve-seat opening, and in a plane below such opening with a lateral hollow extension, a ball-valve working over and in said valve-seat opening, a vertical overflow-pipe fitted at its lower end in said extension of the valve-head, a float arranged over the upper end of the overflowpipe and having at its lower side a sleeve loosely embracing the upper end of the overflow-pipe'and provided in its side with aplurality of ports, a valve-disk fitted within the upper end of the sleeve, and avertical venttnbe fitted in the float and providing communication between the outer air and the interior of the overflow-pipe, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto afliXed my signature in the presence of two witnesses.
