TANK-VALVE.
It has for its object particularly to pro-I vide a valve so constructed that its seat may be reground or renewed without removing the valve itself from its position in the tank, and to provide improved means for preventing the movable valve member lifting too high. I
Heretofore, so far as is known to me, tank valves have been so constructed that when the seat becomes roughened or out of true by corrosion or long continued use, it has been necessary to remove the entire valve from the tank in order to regrind or smooth up the seat. As tank valves are usually soldered to the bottom of the tank, this is a long and expensive process. It has also frequently been found necessary to regrind the valve seat of these valves and in this case the whole valve has been frequently discarded.
The valve embodying my invention is so constructed that the seat may be readily and quickly removed without disturbing the valve body, and the valve seat replaced by a new one which is relatively inexpensive or the old one may be smoothed up or reground and returned to its original position. In either case, the time and expense involved in the repairs is much less than in the case of the valves heretofore in use, and the closet is out of operation for a much shorter time. My new valve is also so constructed that the movable valve member cannot be lifted above a certain point thus preventing the valve catching and a consequent waste of wateigand this is accomplished without the use of a cage above the movable valve member. It will also be seen that by unscrewing the seat ring the guide may be removed from the top instead of being withdrawn through the bottom after removing the flush pipe as has heretofore been necessary with one type of valve.
The invention will be fully understood from the following description taken in connection with the accompanying drawings, and the novel features will be pointed out and clearly defined in the claims at the close of the specification.
In the drawings,-Figure 1 is an elevation of tank valve embodying my present invention with the movable valve member in its raised position. Fig. 2 is a vertical section of the valve shown in Fig. 1 but with the movable valve member seated, this view being upon a somewhat larger scale.
Referring now to the drawings :The floor or bottom of the tank is shown at A, and at B the lining of the tank which is ordinarily of sheet metal and soldered to the valve body. The said valve body is shown at 11 and has a depending screwthreaded portion 12 upon which is threaded the nut 13 which secured the valve in place in the tank. On the extreme lower end of the screw threaded portion 12 is Placed a coupling 14; which secures the flush pipe 15 to the valve body. The movable valve member is shown at 16, and has screwed into its upper end the overflow pipe 17 through which the water in the tank is discharged if it rises above the top of the overflow pipe. A valve washer 18 of leather, rubber or soft metal is located in an annular recess in the 'under side of the movable valve member 16,
and is secured in place therein by the guide 20 which is composed of four radial ribs at right angles with each other and is screwed into the under side of the movable valve member 16. A weight 19 of lead makes the closing of the valve more positive. It will be seen that the movable valve member 16, the overflow pipe 17, weight 19, guide 20, and washer 18 all move as one piece, being lifted by the wire 21.
To an upwardly projecting screw-thread ed flange on the movable valve member 11 is secured a removable valve seat 22 having its upper edge rounded and ground for better contact with the valve washer 18. The upper part of this removable valve seat 22 projects inwardly as shown at 23 and forms a stop which contacts with a shoulder 24 formed on each of the radial ribs of the guide 20 and thereby prevents the said guide and attached parts being lifted farther.
It will be seen that the removable valve seat 22 may be. easily unscrewed from the valve body 11 and lifted out. Afterward, the guide may be unscrewed from the movable valve member 16, and the removable valve seat may be removed and replaced or reground as desired. In either case it is not necessary to remove the valve body 11 from the tank, thus leaving the soldering intact nor to disconnect the flush pipe 15.
The peculiar novel construction of my improved valve much reduces the expense and labor of repairing the valve, as a new removable valve seat is comparatively inexpensive and the old one can be put in condition to be used again atvery small expense. The means employed to prevent the valve opening too wide makes it absolutely impossible for the valve to be lifted high enough so that it can catch and remain open.
What I claim is 1. In a tank valve for water closets, the combination with a valve body secured to the bottom of the tank and having an upwardly projecting screw threaded flange, of a removable valve seat internally threaded a and screwed onto said upwardly projecting flange on the valve body, said removable valve seat having an inwardly projecting flange at its upper side, an internally threaded movable valve member faced with elastic material to form a seat, and a guide upwardly projecting flange on the valve body and seated against said horizontally projecting flat flange on the valve body, said removable valve seat having an inwardly projecting flange atiits upper side, an internally threaded movable valve member faced with elastic material to form a seat, and a guide located within the valve body and secured by screw threads to the movable valve member and comprising radial webs, the lower portion of said guide being of a diameter greater than the bore of the inwardly flanged portion of the removable valve member.
In testimony whereof I affix my signature,
in presence of two witnesses.
