FLUSH-VALVE A'BPARATUS.
Application tiled. January 28, 1924. Serial No. 689,032.
T0 alla/1.7mm it may concern.:
Be it known that I, InviN W. Litissya citizen of the United States, residing at Allentown, in the' county ofjLehigh and State of Feniisylvania, have invented new and useful Improvements in a Flush-Valve Apparatus, of which the following is a specification. Y
My invention relates to new and useful improvements in a flush valveV apparatus which yparticularly relates to the construc-` tion and ,operation of the valve which is commonly known as a ball cock and has for its primary object to provide anexceedingly simple and eective device of this character which is relatively inexpensive in the cost of manufacture although strong and durable and highly effectual in operation. l Another object of the invention is the provision of a vertically operating float cooperating with means to guide the same Vso as to prevent undue swinging and provided with means for adjustably connecting said float with the valve plugY operating means in order to4 determine andregulate the amount of water desired in a tank.
A further object of the invention is to so construct the flush valve apparatus that the majority of the operating parts always be above the water line within the tank so as to eliminate, as far as possible, the vdeteriorating effect of the water and being above the water it may be readily inspected at all times. n
A still further object of the invention' is to provide a compact structure requiring but a very small amount of space for installation.
With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art t0 which this invention appertains, may understand how to make and use the same, I willl `describe its construction in detail, referring by numerals to the accompanying drawingforming a part of this application, in which `Fig. 1, is a sectional side elevation of a flush valve apparatus embodying my invention and illustrating its relation to the bottom of a tank and the highlevel of the water line therein.'
Fig. '2, isa plan view thereof.
and shown in section for illustration of aV construction detail..
F 4,'is a planview of the guide bracket removed from the apparatus.
In carrying out the invention as liei'e embodied, 2 represents the valve casing or body having a main chamber 3 into which pro-` jects an annulus llproviding a seat 5 on its upper edge and'this annulus surrounds the inlet opening 6 leading to the main chamber 3. Also surrounding the inlet opening 6 is an exterior internally threaded boss 7 for the reception of the inlet or stand pipe 8 passing through the'bottom wall 9 of a flush tank such as are commonly used in toilets.
'The main chamber 3 communicates with a ,secondary chamber 10 in the casing or body 2 the latter preferably being of reduced dimensions and formed in an offset portion of the casing. From the bottom of this secondary chamber leads an outlet pipe 11 having threaded connection with the valve casing or bodyy and the lower end of this outlet pipe terminates a short distance above the bottom of the tank so that when water is being supplied to the tank it will be projected into the body` ofA water contained in the tank and thereby eliminate orv reduce to a minimum the noises incident to refilling the tank. From the top of the secondary chamber 1() leads the usual refill tube 12 which has threaded connection with the valve casing or body. As will be obvious thisrefill tube leads to the overflow pipe of the outlet frointhe tank so as to refill the trap after acloset has been flushed.
From the top of the valve casing or body in endwise alignment and concentric with the annulus l projects a tubular Vopen ended cylinder' or bearing sleeve 13 in which is slidably mounted the valve 4plug or plunger 1A having a circumferential groove 15 intermediate its ends to hold a packing ring 16 to prevent the escape of water through the cylinder y13. In' the inner end of the valve plug or plunger is formed a suitable recess 17 for the reception and retention of a packing disc 18 destined to bepressed upon the seat 5. v
The valve casing or body carries a support or arm 19, preferably formed integral therewith, and the upper end thereof projects above the cylinder 13 and has threaded therein a screw 20 or its equivalent with the shank thereof plain or smooth so as to act as a stud axle for the operating lever 2l. tegral hub 22 with which is formed the integral cam 23 to engage the upper outer end of the valve plug or plunger 14, said cam being so arranged that as the operating lever is moved in one direction or raised the valve plug or plunger 11i will be forced inward so that the disc 18 will engage the seat 5. The valve plug or plunger 111 is provided with a yoke 14 having a portion overlying the cam 23 so that when the operating lever is moved in the opposite direction or downward said cam will engage the part of the yoke overlying it and raise the valve plug or plunger as the float descends.
In order to actuate the operating lever automatically by means of the rise and fall Y of the water in the tank l provide a float 24 of any suitable size and shape which float has a tube 25 passing therethrough and projecting from the opposite ends thereof and one of these projecting ends, as 26, coacts with a guide bracket 27 to prevent undue swinging of the float. Said guide bracket is preferably secured to the inlet or stand pipe 8 and has an elongated guideway 2S at its outer end in which the lower end 26 of the tube 25 works. The other or upper end 29 of the tube 25 receives the shank 30 of the link 31 the upper end of said link being bifurcated and pivoted as at 32 to the outer free end of the operating lever 21 and said shank is provided with a series of vertically spaced holes 33 for the reception of a pin 3ft passing through the upper projecting end of the tube 25 thereby providing for the adj ustability of the float relative to the operating mechanism and to establish the amount of water in. the tank to iiX the water line,
From the foregoing description it will be seen that as water flows through the apparatus into the tank and gradually fills the latter said water will finally reach the float 24 and carry it upward causing motion to be transmitted through the link 31, the operating lever 21 and the cam 23 to the valve plug or plunger 14 which will gradually force the latter downward until the packing disc 18 is firmly pressed against the seat 5 thus eifectually shutting off the water supply but as soon as the water begins to flow from the tank the float will descend and cause the cam to raise the valve plug through the medium of the yoke 14', thus unseating the packing disc 18 and allowing the water To flow through the valve casing into the tank through the outlet pipe 11.
As will be obvious upon the removal of the screw 2O the operating lever with its component parts and the v,attached float may Said operating lever includes an in-V be removed and the valve plug or plunger afterwards withdrawn so that the parts may be readily inspected, repaired or renewed.
s the highest level of the `water in the tank reaches only to the water line shown when the parts are set as illustrated in the drawings the majority of the operating parts are always out of the water and will not be affected by the same and even with the water in the tank if the supply is shut off the parts may be removed and replaced without having to place the hands in the water.
0f course l do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.
Having thus fully described my invention, what I claim as new and useful is l. A flush valve apparatuscomprising in combinati on with a tank, an inlet pipe7 a valve casing on the upper end of said inlet pipe, a seat within the valve casing in the region of the inlet pipe, an open ended cylindrical portion projecting from the valve casing above the highest water line in the tank, said cylindrical portion beingl concentric with the valve seat, a valve plug slidably mounted in the cylindrical portion of the valve casing and having a circumferential groove intermediate its ends and further provided with a recess at its lower end, va packing ring within the circumferential groove, a packing disc in the recess for coaction with the valve seat, a supporting arm carried by the valve casing and projecting above the upper end of the cylindrical por tion, a screw having threaded connection with said support, a valve lever journalled on said screw, a cam carried by the valve lever for coaction with the valve plug whereby the latter will be moved when the operat- .ing lever is actuated, a float, means'for ad j ustably connecting said float to the operating lever whereby the latter will be actuated due to the rise and fall of the water in the tank.
2. A flush valve apparatus comprising in combination with a tank, an inlet. pipe, a valve casing on the upper end of said inlet pipe, a seat within the valve casing in the region of the inlet pipe, an open ended cy-` lindrical portion projecting from the valve casing above the highest water line in the portion, a screvv having threaded connection with the support, a valve lever journalled on said screw, a cani carried by the valve lever for coaction with the valve plug whereby the latter Will be moved when the operating lever is actuated, a float, a tube passing through said float and projecting from both ends of a link pivotecl to the operating lever and projecting into the upper end of said tube, said link having a series of vertically spaced holes, means passing through the upper end of the tube and any one of the holes in the link for adjustably connecting the float relative to the operating lever, and a guide bracket carried by the inlet pipe and having an elongated guiclevvay for the reception of the lower projecting end of the tube.
In testimony whereof, I have hereunto afixed my signature.
