Application March 4,
This invention relates to a new and improved flush device; and more particularly to an improved combination valve and operating means therefor, adapted for use on a water-closet iiush `5 tank, and the like. i
With the customary flush devices generally employed on water-closet flush tanks, it is observed that the valve closes rather slowly, in fact so slowly as to produce a lingering seepage of the water during the nal stage of lling the flush tank and completely closing the valve. Such seepage soon causes a groove to be worn into one or both of thepompanion valve elements; and thereupon a continuous leakage takes place, which becomes very annoying to hear and which quickly ruins the valve and causes a considerable loss of water.
Another defect is observed in the arrangement and constructionof the iiush devices now on the market, in that itis n ot an easy matter to get at the companion valve elements for inspecting and repairing the same, without taking much time for loosening and removing a considerable number of screws and parts of the device.
It is an essential object of this invention to remedy the above noted defects, and to provide a flush device which is so arranged and constructed that the valve will bevery promptly closed completely, and the annoying seepage of water, which has heretofore occurred with the ordinary valve devices, will be entirely avoided; and wherein, at the same` time, the valve will not be closed so rapidly as to create injurious back-pressure or water-hammer.
It is another object of this invention to provide such a valve device which eiects apositive and water-'tight closure, preferably by employing a double Aor compound closing means.
It is a further object to provide a flush device so constructed that the valve elements and the gasket thereon can be readily inspected and replaced.
These and various other objects andadvantages are attained with this invention, as will become apparent from the following description, taken in connection with the accompanying drawing wherein the invention is shown in its preferred form; it being understood that various other arrangements andforms of construction may be adopted in carrying out the objects and purposes of this invention.
In the drawing:
Fig. 1 is an elevational view of a ush device having my invention applied thereto.
Fig. 2 is a vertical sectional View thereof, taken 1936, Serial No. 66,983
on line 2 2 of Fig. l, showing the parts in the valve-closed position.
Fig. 3 is a vertical sectional view, similar to that shown in Fig. 2, but the parts being in position In the drawing my invention is illustrated in its y,
preferred forni of construction, comprisinga tubular stem I I having a, restricted sleeve portion or neck I2 extending integral from its upper end, thereby providing a shoulder I 3 at the junction of the two, adapted to have a gasket I 4 seated on the shoulder and surrounding the neck. The neck has its top I5 closed, and has openings or perforations I I in its sides, which provide the valve openings for emitting the water which enters thru the stem I I.
The stem I I is provided with an annular flange I8 beneath which a gasket I9, of rubber or the like, is seated. Said gasket and a nut 20 which'is Said neck I2 provides the stationary valve placed below it on the threaded end 2l of the stem,
provide means for mounting the stern water-tight in the usual opening provided in the bottom kof the ush tank. Y
The movable valve member, which cooperates with the stationary valve member I2, includes a cap or sleeve member 22 which ts water-tight around member I2 and is slidable longitudinally thereon. It is closed at the top 22 of the sleeve, and has a bracket portion 23 thereabove. In its closed position member 22 covers the outlet openwater-tight iit of Vsleeve 22 upon sleeve I2, in c, covering the openings IB; and the other is provided by the sleeve 22 having its lower end seated water-tight upon gasket I4, whereas the upper end 22' of this sleeve is closed. Consequently,
even if long extended use and wear should impair the sealing fit between the two sleeves, yet the sealing fit between the lower end of sleeve 22 and gasket I4 would be suicient to prevent leakage or seepage, as occurs in the ordinary valves of this type of device; and the gasket I4 can be Cil cheaply and readily replaced if necessary, for maintaining a water-tight seal.
A dome-shaped deflector 25 is preferably also provided, including an upper collar 26 which slidably embraces sleeve 22; and a lower internally threaded collar 21 depends from the bottom wall 28 of the deflector, being detachably mounted on the externally threaded upper part 29 of stem The inner part 28 of wall 28 extends inwardly from collar 21 and engages upon the marginal edge portion of gasket |4, for holding it in place. Slots 30 are provided in the outer part of wall 28, to emit the water which iiows thru openings I6 and is then deflected by the dome-shaped portion downwardly thru said slots.
The frame for supporting the valve operating means is of an open construction, and provides convenient access to the valve elements. It includes a pair of standards or supporting bars 3|, each of which is preferably formed from a metal plate that is substantially straight across its lower end 32 and has its two edge portions 3|' bent inwardly to an increasing extent from the lower part toward the upper part 33, thereby becoming channel-shaped ravt-fthe upper-part orend 33, substantiallyasindicated in the ldrawing. l`The pair of lower ends 32 of the pair of standards 3| are detachably secured, with screws or the like, toa pair of uptur-ned-.lugs 34 providedron flange |8..of stemd I; and a head orY topV member 35 has a pair-of depending lugs 36 secured in the two upper channel ends 33 ofthe standards 3|, substantially as shown.
The means for operating the valve includes a float-controlled quick-acting toggle mechanism 4U andan operating shaft 4| extending therefrom, thru an opening 42 provided in head member 35, to the bracket portion 23 on the movable valve sleeve 22. ,The shaft is detachably connected to the bracket portion 23, by a screw 43 or similar element which can be readily reached and removed thru the space between standards 3|. The shaft 4| canlthen be swung aside and the valve sleeve 22 can be readily withdrawn from valve sleeve I2, and the deflector 25 with its integral collar 21 can be unthreaded and removed from stem II, whereupon the gasket I4 can be readily removed and replaced by a new one. The valve sleeves can thus be inspected by merely removing screw 43 and withdrawing valve sleeve 22, and the gasket can likewise be readily replaced by removing only screw 43 and the deflector 25 and sliding sleeve 22 up from sleeve I2.
The toggle mechanism includes a float-controlled lever ,44,- and a valve actuating lever 45, also 'spring means 46 whichis'pivotally connected with the two levers, so as to impart a quick or snap action from operating lever 44 to valve actuating lever 45 and therefrom to operating shaft 4| and the connected valve sleeve 22, and prompty close the Valve openings I6 in sleeve I2 and' seat sleeve 22 firmly upon gasket |4.
The operating lever 44 preferably has its main part 41 constructed from two bars, one pair of the ends of said bars being pivotally mounted at the outer sides of a pair of lugs 48 which arise from head member 35, a pivot element 49 extending thru said lugs and the lever ends. Between saidilugs 48.the valve actuating'ilever 45 is pivotally mounted upon the pivot element 49. Spacing washers 59 may be interposed 'between lever 45 and lugs 48, as shown. 1
- Spring means 46 includes a casing or tube 5| closed at one end 52from which extend spaced perforated ears 53 engaging one end of actuating lever 45 therebetween, a pin 54 extending thru said leverv and said ears for pivotally connecting the lever with the spring means. A compression spring 55 is disposed in this tube 5|, being conned between the closed end 52 and a pin 56 which is detachably mounted near the swingable ends of lever bars 41 and is adapted to move in a slot extending longitudinally of tube 5|, While the toggle mechanism is in operation.
The valve actuating lever 45 is pivotally connected to the operating shaft 4|, by a pivot pin 58, intermediate the pivot elements 59 and 54, and includes a hook or trigger-like stop portion 59 which is movable between spaced channel portions 60 extending from a tubular pocket 62 provided on head member 35. A spring 6| is seated in this' pocket and urges hook portion 59 outwardly, to aid in depressing shaft 4| and valve sleeve 22 into the valve-closed position, as shown in Fig. 2. Said hook portion may bear against the wall of pocket 62 or against standard 3| to limit its movement in the valve-open direction, as shown in Fig. 3; while its movement in the valve-closed direction is limited by the firm pressing of sleeve 22 upon gasket I4.
The float-controlled-operating lever 44 has an arm or rod 63 adjustably connected to the bars of its main part 41, said rod having the customary float ball 64 attached to its outer end. The adjustable connection is preferably provided by the use of amember V65 which includes a socket wherein the rod 63 is threaded, said member also including a plate portion 66 which ispivoted by a pin 61 between the swingable ends of bars 41 of lever 44. A thumb screw 68 is placed in the-extreme` ends of said bars 41 and extends thru an arcuate slot 69 provided in plate 66, which permits swinging of plate 66 on pivot pin 61 for the vertical adjustment of rod 63-and float 64 with respect to the main part of lever 44, whereby to control the position of the water-level in the flush tank.
When operating lever 44 has been moved sufciently, thru the action of float 64, so that the center line of this lever has passed beyond the f center line thru pivot pins 54, 58 and 49, then the compression spring 55 becomes operative, which is at that position compressed, and with a quick snapping action moves the valve actuating lever 45 with the shaft 4I and the movable f valve sleeve 22 fromone o-f the valve'positions, as shown in Figs. 2 and 3, to the other. 'I'he compression 'spring' 6|, which is weaker than spring 55, aids in promptly moving valve sleeve 22,into its closed position and in holding the valve rmly closed lupon the gasket I4. The valve openings I6 are made of the proper siz'e and number to aord the prompt closing of the valve, and at the same time to prevent any extremely rapid closing thereof which might produce detrimental back-pressure or water-hammer.
