Application filed November 23, 1907. Serial No. 403,e57.
To all whom it may concern:
Be it known that I, Jonson E. Lone- STREET, a citizen of the United Stat, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Flushing Apparatus, of which the following is a specification. r
This invention relates to flushing apparatus for closets and analogous uses, and has special reference to an improvement in that type of valves or valve devices commonly termed closet valves and designed for use in connection with flushing tanks for water closets.
To this end the invention has in view the provision of a simple and practical construc tion of flushing valve device controlled throu h the medium of a conveniently ar-' range operating lever and arranged whollyexterior to the flushing or supply tank so as to provide an arrangement WhlCll does away 7 entirely with the fioatand the more or less objections to the ordinary float and equivalent mechanism are entirely obviated by the present invention.
WVith these and many other objects in view which will more readily appear as nature of the invention is better understood the same consists in the novel construction com bination and arrangement of parts hereinafter more fully described and illustrated in the claims.
In the preferably embodiment of the invention the construction shown in the drawings is used, in which drawings-- Figure 1 is an end view of a flushing tank equipped with a flushing valve device constructed in accordance with the presentinvention. said device being shown in secti n. Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1. Fig. 3 is an enlarged detail view of the variable regulating relief valve for the dash-pot.
Like references designate corresponding parts in the several figures of the drawings.
In carrying out the present invention no i is required. This tank as shown ln the drawings is designated by the numeral if and comprises an ordinarybor tank ofany' design or capacity, but preferably provided at its bottom with an inlet fitting 2 designedfor the connection therewith 'ofa water supply pipe in constant open communication with the interior of the tank, thereby providing an arrangement wherein the pressure from the source of water supply is a constant force within the tank and is utilized in connection with the operation of the I flushing valve device as will presently ap' The tank referred to has associated therewith the improved flushing valve device y formingthe subject matter -of this ap lication. The said valve device includes in its organization a main valve body which ma be properly termed a valve casin designated by the numeral 3 and arrange preferably in an 11 right position beneath the flushing or sup y tank 1, said casing having a detachab e threaded or equivalent connection lat its upper end with the outlet fitting 5 30 which is provided at thebottomof the tank and has an unobstructed constant communi cation therewith. j I e The upright valve casin is formed'at its lower end with what may be termed an outlet chamber 6 provided atone side with a lateral pipe neck 7 forming the outlet opening for the valve device and designed to have coupled thereto the pipe leading to the closet bowl. At its bottom. the said loweroutlet' chamber 6 of the valve casing is provided with a clean-out opening .8 having threads to detachably receive therein the exteriorly threaded clean-out screw plug 10 forms the bottom closure for the-valve casing and is readily removable for clean -out put-"f;
poses as will be readily understood" bythose familiar with this class of devices. The said bottom plug 10 is of a suflicient depth to permit. of the formation therein, at its inner side, of an open-ended chamber ll'forming a bottom dash-pot the functions of which will presently ap ear. Wall of this chamber 11 i'sa small port 11, affording communicationv between chambers 6 and 11, through which water. may ass slowly from the former to the latterw en the plunger-head 17 is above the port.
I special kind or construction of'flushing tank 55 Through the shell or Y r l communication with the bottom, or closed 12 in communication with the dash-pot chamber, is covered and uncovered through the medium of arelief. valve 13 yieldingly held to its seat by a pressure spring let interposed, between the same and a tension screw 15 adjustably mounted in a threaded opening 16 in one side of the bottom plug 10, and
whose head is exposed on the exterior of the head for adjustment purposes to regulate the tension of the spring 14, and hence control the acceleration or retardation of the escape of water from the dash-potbeneath the plunger head 17 operating therein.
In addition to the elements mentioned the valve casing 3 is provided with an interior main valve seat 18' separating the outlet chamber, 6 from the main valve, chamber 19, within which latter operates the saucer-shaped, or equivalent, cut off valve 20 desi ed to close onto the seat 18 to cut off the ow of water through the outlet chamber 6. The cut ofi valve 20 has rigidly connected or formed therewith the upper and lower valve stem members 21 and 22 respectively, the latter of which is connected to and carries the plunger head 17 referred to. The upper valve stem member 21 is connected to and carries a piston head 23 slidably fitting within an auxiliary pressure cylinder 2 L This cylinder is arran ed within the valve chamber 19 in an npri ht position and is spaced from the walls of t e valve chamber, said cylinder being closed at its upper end and open at its lower end. The said piston head 23 and plunger head 17 may conveniently be of duplicate construction and provided with the well known cup leather packing disks, although any equivalent construction would ,subserve the functions of the invention. However it is to be observed that the piston head 23 is of less diameter than the cut off valve 20 so that an excess or'superior water pressure is exerted on said valve 20. a
' The pressure cylinder 24 may be conven-.
iently supported .in place by means of a I vconnected therewith one end of a by pass spider or skeleton su portin frame 25 secured to the walls -0 the va ve casing and having a threaded or equivalent collar 26 embracing the cylinder. Also, the closed end portion of the cylinder 24: has suitably relief pipe 27 the other end of which pipe is in communication with the outlet chamber 6,
as at 28, and said pi e 27 is fitted between its ends with a suitab ecut off or controlling valve 29.
l Thev main cut 03 valve is lifted by. a me chanical lifting device preferably consisting of a swinging operating lever 30, a rocker shaft 31 and a pair of swinging lifting arms 32. The arms 32 are fitted to the rocker shaft 31 within the outlet chamber 6 and are providedwith forked or bifurcated free ends 33 engaging thestuds 34 rigidly carried by the lower valve stem member 22. Said shaft pressure from the tank will be exerted on the valve 20 and the piston head 22, but on account of the larger diameter of the valve 20 said valve will be held to its seat by its own' Weight assistedby the excess pressure thereon. When it is desired to flush, the lever 30- is swung in a direction to lift the arms 32 and hence lift the parts 17, 20 and .23, thus permitting the water to have free outlet through thefchamber 6 and thence to the bowl. In this operation the lifting force required is quite slight, simply that necessary to overcome the excess ressure on the valve 20 plus the Weight 0 the. arts and the resistance of the air in-the cy inder 24.
After the tank has emptied itself the weight I of the valve stem and its equipments, assisted by the pressure of the compressed air in the upper part of the cylinder 24 will close the valve 20 and the speed of closing will be regulated by the relief device described which is associated with the dashpot 11; The time allowed for the valve 20 to close will be determined by the uantity of water which it is desired to have ow.
By opening the valve 29 in the by pass pipe 27 the cylinder 24:. may be'relieved of any accumulation of water through a lifting movement of the piston head 23, after which the valve is usually closed. Onif desired, the valve 29 may be left slightly open to regulate the resistance offered to the upstroke of the piston head 23.
1. In a 'flushin with the tank, 0 a valve casing communicating with said tank and having .an interior valve seat, and an outlet chamber below the latter, a main cut-off valve having an upper and a lower stem member, a piston head-carried by said up er stem member, a plunger head carried y the lower stem member, a separate closed air pressure cylinder supported in a stationary the-'valve seat and 'receivlng said piston head, a-valved relief connection providin communication between the air cyhnder an device, the combination position. above valved pipe connection between 'said closed cylinder and the outlet chamber of the easing, a dash-pot arranged below the valve seat and provided with pressure regulating means, a plunger head carried with the cutoff valve and working in the dash-pot, and an operating device for lifting the main cutoff valve and the parts carried therewith.
3. A flushing device comprising a'valve casing having an interior valve seat and an outlet chamber, a main cut-01f valve workmg above and onto the valve seat, a piston head carried with the main cut-oil? valve and arranged above the, san1e,'a plunger head carried with the main cut-ofi valve and arranged below the same, an an pressure cylinder supported within the casing in spaced relation to the walls of the latter to admit of the assage of water thereabout said cylinder eing closed at the top and open at the bottom and receivin through its open end the said piston hea areliet connection providing communication between the air cylinder and the outlet chamber of the casing, a plunger head, and lifting the main' cut-oil carried therewith.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
