Description

Oct. 23, 1956 c. IVERSON TOILET DISCHARGE VALVE CONTROL APPARATUS Filed June 11, 1954 INVENTOR 01m n/mso/v BY fem, WQLWZ flTTOR/VEYS.
United States Tatent O TOILET DISCHARGE VALVE APPARATUS Carl Iverson, Long Beach, Calif. Application June 11, 1954, Serial No. 436,131 4 Claims. (Cl. 4-55) CONTROL dividual toilet bowl. In almost every instance however the conventional discharge valve control apparatus permits an excessive amount of water to flow from the flushing tank during a flushing operation.
It is a major object of the present invention to provide toilet discharge valve control apparatus which permits only the exact amount of water necessary for completing an effective flushing operation to be discharged from the flushing tank. In this manner a considerable saving of water may be effected.
Another object is to provide apparatus of the aforedescn'bed nature which permits the water to be discharged from the flushing tank at the same head as with conventional discharge valve control apparatus.
A further object is to provide apparatus of the aforedescribed nature which may be readily installed within a flushing tank in a minimum amount of time and effort by the ordinary householder. Such installation requires no special tools.
An additional object of the invention is to provide a novel toilet discharge valve control apparatus which effects a positive seating of the valve stopper whereby no water leakage will occur.
Yet a further object is to provide toilet discharge valve control apparatus that is useable as a replacement for the original discharge valve control apparatus furnished with the conventional toilet.
A still further object of the invention is to provide apparatus of the aforedescribed nature that is simple of design and rugged of construction whereby it may provide a long and trouble-free service life.
These and other objects and advantages of the present invention will become apparent from the following detailed description of a preferred embodiment thereof, when taken in conjunction with the appended drawings wherein:
Figure 1 is a side elevational view of a preferred form of toilet discharge valve control apparatus embodying the present invention;
Figure 2 is a top plan view of said apparatus; and
Figures 3 and 4 are reduced side elevational views showing the mode of operation of said apparatus.
Referring to the drawings, the preferred form of toilet discharge valve control apparatus is shown mounted within the flushing tank of a conventional toilet. This tank has a bottom wall wherein is mounted a discharge or flushing pipe 12 that is connected at its lower end with a toilet bowl (not shown) in a suitable manner. The upper end of the discharge pipe 12 terminates in a valve seat 14 that receives a stopper 16 whereby the flow of flushing seat 14.
water is controlled. Formed a side extension 18 of the the actuating handle (not The discharge valve control apparatus includes a horizontally extending bracket, generally designated 30, one
the bracket 30, relative to the overflow pipe 20, may be adjusted by means of a screw 34 carried between bifurcations 36 formed on 34 serves to control the diameter of the overflow pipe-encircling bore 38 of the clamp 32. The free end of the bracket 30 is formed with a vertically extending bore 40 of somewhat greater diameterthan that of the stopper rod 22 whereby the latter is freely movable vertically with respect to the bracket.
the overflow pipe 20 and are rigidly secured, as by welding, at their left-hand ends to the float 56. The opposite end of these bifurcations 60- merge into a pair of bored connection elements 62 which are secured to the pivot arm 46 as by bolt and nut combinations 64, or the like. The free ends of the connection elements 62 are so spaced that the bores 66 thereof may be aligned with any two of the bores 54 of the pivot arm 46, as indicated in Figure 1.
In operation, the parts of the discharge valve control apparatus will normally be disposed as indicated in Figures l and 2, the stopper 16 being held seated in the valve When it is desired to flush the toilet bowl the stopper rod, and hence the stopper 16, are raised as indicated in Figure 3 whereby water 21 will flow downwardly into the discharge pipe 12 from within the flushing tank. The stopper 16 will be maintained in a raised position because of the frictional engagement of the shoe 52 with the stopper rod 22 within the confines of the saddle element 42. This frictional engagement will continue so long as the float 56 is in a buoyant condition, that is so long as the level of water 21 is above the float. During this frictional engagement the saddle element 42 will provide a rigid backing for the stopper rod 22.
Referring now to Figure 4, as the water 21 flows downwardly through the discharge pipe 12 its level will gradually drop until it falls below the top of the float 56. At this time the float 56 will sink and thereby allow the pivot arm 46 to pivot in a counterclockwise direction from its firmly seated in place.
The exact water level at which flow through the discharge pipe is stopped may be controlled both by the elevation at which the bracket member 30 is secured to the overflow pipe 20 and the choice of spaced holes 54 utilized to connect the bracket member 58 to the pivot arm 46. These adjustments may both be accomplished by even an unskilled householder utilizing solely a screwdriver once the exact amount of water required for complete eflective flushing of the particular toilet bowl has been determined. It shouldbe noted that the use of a weighted stopper 16 substantially eliminates the danger that the stopper rod 22 might stick while in a raised position and thereby permit water to leak into the discharge p pe- While there has been described hereinbefore what is presently considered to be the preferred embodiment of the present invention, it will be apparent that various modifications and changes may be made with respect thereto without departing from the spirit of the invention or the scope of the following claims.
I claim:
