WALTER J. KIRKHAM, 0F HELENA, ARKANSAS.
SEAT FOR FLUSH VALVES.
Application filed April 4, 1922. Serial m'54a451.
To all whom it may aoncem:
Be it known that I, WALTER J. KnaxHAM, a citizen of the United States, residing at Helena, in the county of Phillips and State of Arkansas, have invented certain new and useful Improvements in Seats for Flush Valves, of which the following is a specification.
This invention relates to valve construction and more particularly to float valves as commonly employed upon flush tanks oi various kinds, and its primary object is to provide reliable and eflicient means whereby the valve seat may be readily removed when worn and replaced without removing or disturbing the other parts.
A further object, among others, is to provide reliable and efficient means whereby the valve seat alone may be quickly removed and reground, if desired, or replaced with a new seat without in the least disturbing the connections of the discharge tank pipe to the tank.
A further object, is to provide a valve seat for flush tanks that can be readily locked into position without the use of lock nuts or screw threads.
A further object is to provide a valve seathaving an extended body portion adapted to extend within the discharge pipe and having an opening therein adapted to aline with an opening in the vent pipe, which is usually found in flush tanks to which this invention pertains.
Other objects and advantages will be hereinafter made clearly apparent in the following specification, and by reference to the accompanying drawings in which Figure 1 shows my improved float valve complete.
Flgure 2 is a top plan section taken on line 22 of Fig. 1.
Figure 3 shows a side view of my valve seat removed.
In many of the flush valves now in use, some difliculty is encountered in the removal of the valve seat after considerable use, when it becomes necessary for repair. This is due in a large measure to the corrosion of metals and the peculiar methods of procuring the valve seat in position in the discharge pipe.
My idea therefore is to provide a removable seat for outlet tubes above the side flush tank, in which the seat may be readily removed for the purpose of being reground or in case same is entirely worn out to be replaced with a new valve seat. This object can be accomplished without the use of tools of any description and furthermore it is not necessary to shutoff the water supply as my improvedvalve seat can be instantly removed without in any way disturbing the rest of the parts.
Referring to the drawings in detail, like numerals will be used to designate like parts throughout.
The numeral 1 designates the bottom of a tank of the usual construction provided with the usual metallic lining 2, while 3 indicates the discharge pipe having a vent pipe 4 connected with same between the valve seat and the flooring of the tank. The aforesaid vent pipe 4 extends upwardly in the tank and is adapted to care for any overflow of water.
The discharge pipe or tube 3 is provided with a throat extension 6 in which the vent or overflow pipe 4 is balanced, and said throat extension forming a passageway between the pipe 4 and the discharge pipe 3. A gasket 7 and a gasket 8 held in place by a nut 9, firmly fasten the discharge pipe to the bottom of the flush tank and prevent the possibility of leakage around the connection.
Resting on the flared upper end of the discharge pipe 3 is a gasket or packing 3 upon which is supported a valve seat 10, the latter being provided with a depending body portion 11 which extends downwardly into the discharge pipe 3, as clearly shown in Fig. 1 of the drawing. The body 11 is provided with a pair of bayonet oints indicated by the numeral 12 and adapted to engage ears 13 carried by the inner walls of the discharge pipe and forming a look therewith. The body 11 is provided with an opening 14, that registers with the communicating passageway of the throat 6 when the valve seat is locked into position.
A float valve 15 provided wih the usual controlling valve stem 16 works in a guideway 17 carried by the arm of the bracket 18 which is supported by the vent pipe 4. From the above it will be readily understood that in removin the valve seat 10 for the purpose of regrinding or replacing with a new valve seat, the float valve stem 16 is raised, permitting the discharge of water from the tank, and when the water has receded to a point below the enlarged head 3 of the discharge pipe, the operator can quickly remove the va ve seat by grasping same firmly and turning to the right or left as the case may he; thereby uncoupling the bayonet joint from the ears or lugs 13, and in replacing the valve seat the same opera-- tion is followed, except that after the body of the valve seat has been placed in the dis charge pipe as far as the same will extend, the valve seat is turned to the leiit thereby firmly locking same in place by means of the bayonet joint and the lugs 13.
lY-hat I claim is:
In a flush tank, thecomhi-nation with an outlet pipe provided with an opening in its wall adjacent the upper encl-thereof,-the.1 1pper end of said pipe being flared outwardly a laterally extending throat formed on the upper portion of said pipe and in communication with said opening, and a vent pipe connected with said throat; of a valve seat provided with an outer. peripheral offset portion for reception on the upper flared end of said outlet pipe, an integral tubular body extension formed on said seat in continnation of said annular ofi'set portion there n, said body. extension being provided in its wall with an opening adapted for registration with the opening in the wall of the outlet pipe, said body extension being also provided at diametrically opposite points thereon with bayonet slots extending upwardly from the lower edge of said extension, and inwardly extending ears carried at diametrically opposite points onthe wall of said pipe for reception in said hayonet slots to. removahly secure said valve seat in position on the upper end; of :said pipe the opening in the body extension bein;;' intermediate of said bayonet slots. whereby. said opening "may only register with the opening in said outlet pipe when; the bayonet slots and thevalve seat are disposed to locked position, as and for the PHBPOSBS described.
Tn test-nnony whereof Infill: my signature.
