TOILET' TANK LEVER Filed Sept. '7, 1955 2 Sheets-Sheet 2 Invenlo;

fiawaolizm A llomey Patented Nov. 17, 1936 UNITED STATES PATENT OFFIEE 4 Claims.

My invention relates generally to a toilet tank, and particularly to a toilet tank of the type having a flushing valve controlled by a lever actuated by electrical means, and an important object of the invention is to provide an arrangement of this character which is electrically and mechanically efiicient.

Another important object of the invention is to provide means for eliminating the corrosion, breakage, and excessive wear which is incidental to ordinary manual tank levers of this class.

Another important object of my invention is to provide an arrangement of the character indicated above whereby the flush valve is more strongly yet removably supported on the tank while being more efficiently and reliably operated with less trouble to the operator.

Other important objects of my invention will be apparent from a reading of the following description in connection with the drawings, wherein for purposes of illustration I have shown a preferred embodiment of my invention.

In the drawingsz- Figure 1 is a side elevational view of a closet tank having the wall thereof broken away to disclose the electrically operated tank lever and flush Valve.

Figure 2 is an enlarged side elevational view showing the electrical arrangement.

Figure 3 is a top plan view of Figure 2.

Figure 4 is a transverse vertical sectional view taken through Figure 3 approximately on the line 4-4.

Referring in detail to the drawings, the numeral 5 generally designates a toilet flush tank or the like which includes the removable top 6, the flush valve seat I, and the pipe 8 connected thereto which leads to the toilet bowl or the like.

The present invention eliminates the extension of the tank lever through the side of the tank and the usual handle or chain which is used to operate the same, the entire arrangement being confined within the tank.

Referring in detail to the drawings, particularly Figure 2, the numeral 9 generally designates one of the interior walls of the tank 5 to which is attached by attaching means [0 an upwardly extending ear II on the cylindrical brass or other suitable material casing 12 which has the closed bottom l3 and contains a solenoid coil I 4 which rests on an insulating washer [5 which is disposed between the bottom of'the coil and the bottom l3 of the container l2. Resting upon the upper end of the coil I4 is a dielectric washer I6 which also acts as a closure for the top of the container; and

acts as a support for the upper end of the insulating sleeve H which is inserted in the opening thereof and has its lower end resting on the bottom of the casing and traversing a similar concentrically aligned opening in the washer l5. 5 The leads l8 from the solenoid coil traverse the side of the casing and connect with a switch l9 on the exterior of the tank 5. Ihe switch is preferably of push button form located within convenient reach of the operator. switch will be connected to a suitable source of electrical energy (not shown), whereby the solenoid coil M will be energized upon pressing the push button or otherwise operating the switch.

The fastening means If] comprises the head 35 which lies against the outer side of the wall 9 and has projections 36 which dig into the wall and prevent the head from turning. The projections 36 also serve to prevent rotation of the head 35 relative to the square shank (all which traverses the wall 9 in a conforming opening.

The inner end of the shank 31 is fastened to the ear II on the casing I2. Both the shank 31 and the ear I l have abase extending therethrough which receives the bolt 38 which has one end fastened to the head 35 and its opposite end extending inwardly beyond the ear I l and equipped with a washer 39 and a clamping nut 40.

The described fastening means It) not only positively prevents unwanted rotation or swinging of the casing l2, but provides a strong mounting for the casing I2 and the mechanism which it supports, besides preventing working loose of the parts which would permit misalignment of the parts and fracturing of the enamel usually covering closet tanks. In addition the head 35 adds to the appearance of the tank while hiding the hole in the tank wall through which the shank 31 passes. 40

Removably mounted on one side of the upper part of the casing l2 by removable fastening means 20 is the pivot bracket 2! which is preferably of brass or other suitable material in the form of a flat bar the upper part of which is bent at right angles as indicated by the numeral 22 and provided with a pivot hole 23 which receives a cotter pin 24 which forms the pivot for the horizontal lever 25.

The cotter pin pivot 24 traverses the lever 25 near its right hand end which extends over the solenoid magnet and has depending therefrom the laminated solenoid core 26 which slides in the insulating sleeve I1 and is pivotally attached to the right hand. end of the lever 25 by a U-shaped Of course, the 10 I link 21 which has inwardly bent ends pivotally engaging holes in opposite sides of the core as illustrated in Figures 2 and 4.

The opposite or left hand end of the lever 25 has a number of holes 28 therein with any one of which is adapted to be engaged the upper end of the operating link 29 which has an eye on its lower end engaged with another eye as indicated by the numeral 30 whereby a flexible connection is made with the shank 3! on the compressible material valve 32 which normally seats in the valve seat I l as illustrated in Figure 1 and retains the water within the tank 5. The shank 3| works through a guide 33 on the side of the tank.

By means of the arrangements described, energization of the solenoid coil 14 by operation of the switch I9 will cause the core 26 to be drawn downwardly into the solenoid and thereby tip up the left hand end'of the lever 25 and exert the necessary upward pull on the operating link 29 to draw the valve 32 upwardly and cause the Water in the tank 5 to empty into the pipe 8 for flushing purposes.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claims.

What is claimed is:

1. In combination with a toilet flush tank or the like having a vertical wall and a bottom, said bottom containing a flush valve seat, a casing attached to the wall, a flush valve normally seating on said valve seat, a lever having operative connection to said flush valve, and electrical means supported by said casing for operating said lever to open the flush valve, said casing having a lateral squared shank fitting in a squared hole in the wall of the tank, and means engaging said shank and the tank and holding said shank in place.

2. In a toilet tank having electrically operated flush valve mechanism, said mechanism including a. solenoid, a casing holding said solenoid, said casing having a single laterally extending shank on its side arranged to traverse the side of the tank for supporting the casing relative to the tank, and means engaging said wall of the tank and said shank, said means being arranged to fasten said shank and prevent rotation of said casing relative to said tank.

3. In a toilet tank having a side wall, a vertical casing mounted on the side wall of the tank, a vertical solenoid magnet having its bottom and sides enclosed by said casing, a horizontal lever fulcrumed on the top of said casing and provided at its outer end with toilet tank valve operating means, and a solenoid core operatively depending from the inward end of said lever and working in said solenoid.

4. In combination with a toilet flush tank or the like having a vertical wall and a bottom, said bottom containing a flush valve seat, a casing attached to the wall, a flush valve normally seating on said valve seat, a lever having operative connection to said flush valve, and electrical means supported by said casing for operating said lever to open the flush valve, said casing having a lateral squared shank fitting in a square hole in the wall of the tank, and means engaging said shank and the tank and holding said shank in place, said shank being tubular, and said means comprising a bolt passing through the bore of said shank, said bolt having a portion engaging the exterior of said wall of the tank.
