INVENTOR.
JAMES M. TEAHEN FIG.3.
, BY www.. "AMM 5M ATTOR N EYS United States Patent() Margaret E. Teahen, Detroit, Mich., and one-fourth to Mary E. Conrad, Wooster, Ohio Application october 1,1951, serial'No. 249,199
9 claims. (ci. 4-68) The invention relates to ushing tanks, and it is the object of the invention to obtain a construction which has various advantageous features and avoids defects that are common in constructions heretofore used.
More particularly, it is an object of the invention to obtain a construction of tank in which the water inlet pipe is confined within the area of the walls of the tank and at the same time is completely out of contact with the water within the tank. t Y
It is a further object to obtain a construction in which the ball cock is rigidly mounted on the tank within the same and located above the highest possible water level therein.
It is a further object to obtain a construction in which the ball cock with the water supply pipe connected therewith may be assembled with the tank by inserting the pipe through an aperture in the seat to extend downward through the bottom of the tank and secured by clamping means below said bottom.
With these and other advantageous features in view, the invention consists in the construction as hereinafter set forth.
In the drawings:
Fig. 1 is a rear elevation through a portion of a water closet flushing tank incorporating my improved construction;
Fig. 2 is a horizontal section on line 2 2, Fig. 1;
Fig. 3 is a vertical section on line 3 3, Fig. 1; and
Fig. 4 is a plan view partly in section.
The tank A may be of the usual rectangular form in cluding a vertical rear wall B, an end wall C and a bottom D, all of integral construction. One of the walls, and preferably the rear wall B, has an inwardly otset portion E of substantially U-shaped cross section which is open at the rear. This portion E extends upward with'- in the tank from the bottom to a point that is above the highest possible Water level in the tank, terminating in a seat for the ball cock F. This seat is apertured at G for the passage downward therethrough of the water supply pipe H, which also passes through the bottom D and is secured by a nut I beneath the bottom engaging a threaded portion of the pipe. Thus when the nut I is tightened this rigidly secures in position both the pipe H and the ball cock F. A squared portion .l on the pipe H located in the slot through the bottom D holds the pipe from turning when the nut I is tightened. It is to be understood that the tank is provided with an overflow conduit and preferably also an emergency spill port, neither being shown, which absolutely precludes rise of water within the tank to the level of the seat for the ball cock. Consequently neither the pipe H nor the ball cock F ever come into contact with the water within the tank.
To understand the advantage of such construction reference is made to the fact that water closets are frequently installed in locations where the water supply has a certain degree of corrosive action upon metallic parts. It has been found that where a water supply pipe passes upward from the bottom through the water within the tank, it may in time become porous due to the eating away of certain of its constituents. It is also a fact that water supply systems are frequently subjected to internal suction when repairs are beingmade so that a supply pipe to the ball cock, which passes through the water of the tank, may permit seepage of water into the system. Consequently, if the water in the tank is contaminated, which also is a frequent occurrence, the whole water system i may also be contaminated. With my improved construction such result is impossible for no portion of the water supply pipe, including the ball cockcomes in contact with the water which is within the tank. Another advantageous feature is that the ball cock is rigidly mounted within the tank and will not be displaced by any ad. justment of the connections thereto. For instance the` *i rock arm, which extends from the cock to the ball or float, may require bending to adjust the height of the normal water level. This can be accomplished without displacement of the ball cock.
What I claim as my invention is:
l. A water closet ilushing tank having an inwardly oiset portion in a vertical wall thereof forming an out-` wardly open channel, said oiset portion terminating be-l low the top of the tank but above the highest possible water level therein, the supply pipe for the ball cock extending downward through said channelV which latter being outwardly open prevents accumulation of leakage water therein.
2. The construction as in claim l in which the channeled offset is in the rear wall of the tank Where it will be concealed from view.
3. The construction as in claim 2 in which said ball cock is rigidly secured on its seat by clamping means on said pipe below the bottom of the tank.
4. The construction as in claim 2 in which the upper end of said inwardly offset portion forms a seat for the ball cock within the tank and said supply lpipe extends straight downward through said seat and said channel.
5. In a water closet tank adapted to contain a body of water for flushing purposes and housing a ball cock having a valve body arranged above the normal level of said water body, the combination therewith of means for protecting the supply of water to said valve body against possible contamination by said water body, said means comprising a channel extending upwardly from the bottom of said tank to a point above said level, said channel being unlled with water and having a drainage opening to prevent any accumulation of water therein, a water supply pipe arranged in said channel in spaced relation to the wall thereof and having its upper end connected with said valve body, and means for mounting the lower end of said pipe on said tank.
6. In a ushing tank, a ball cock within the tank above the water level therein, a water supply pipe extending upward to said ball cock and concealed by the tank, a wall extending above the water level and separating the water in the tank from said pipe and forming a dry chamber through which said pipe passes, said chamber having a drain opening for escape of any water entering therein, and said wall terminating below the top of the tank forming a space above said wall for installation of said ball cock.
7. In a water closet tank having a bottom wall and a side wall which surrounds a ball cock assembly including a valve body arranged above the normal level of a body of water adapted to be retained in said tank for flushing purposes, the combination therewith of means for protecting the supply of water to said valve body against possible contamination by said water body, said means comprising a dam wall arranged within said tank and extending above the highest level of the water lin said tank to form a compartment unfilled with water,
said dam wall having thev upper end substantially below the height of the tank to form a space within the tank and above the top of said dam wall for receiving said ball cock assembly, a water supply pipe rising from the bottom of said compartment and arranged in spaced relation to said darn Wall and having a vertically extending upper end connected to the valve body of said ball cock assembly, means mounting the lower end of said pipe on said tank, and drainage means for said compartment at the lower end thereof.
8. In a water closet, the combination of a tank forming a reservoir for the ushing Water and having surrounding side walls, a ball cock assembly including a valve body within said tank and above the highest water level therein, a separating wall within the area bounded by the surrounding walls of said tank and extending from the bottom of said tank upwardly above said highest water level, thereby forming a dry chamber within said area bounded by the surrounding walls but separated by said Wall from the water in said tank and having no water connected therewith, said dry chamber having a drain opening for escape of any water entering therein, said separating wall having its upper end terminating below the height of said tank to form a space within said tank and above said separating wall, said ball cock assembly being adapted for installation in said space, a water supply pipe extending through said dry chamber from the bottom of said tank to above said water level and concealed Within the area bounded bythe surrounding walls of said tank, the upper end of said pipe extending vertically above the top of said separating wall and directly connected to said valve body.
9. In a water closet tank adapted `to contain a body of water for flushing purposes and housing a ball cock having a valve body arranged above the normal level of said water body, the combination therewith of means for protecting the supply of water to said valve body against possible contamination by said water body, said means comprisingL a channel extending upwardly from the bottom of said tank to a point above said level, said channel being unlled with water, the portion of said botom within the contines of said channel having an enlarged opening therein, a water supply pipe arranged in said channel in spaced relation to the'walll thereof and having its upper end connected with said valve body, and means adjustably mounting the lower end of said pipe on said bottom portion adjacent said opening and only partially covering said opening.
