June 28, 1960 w. K. MEISTER HANDLE ASSEMBLY FOR FLUSH TANK Filed May 27, 1959 INVENTOR.

By WILLIAM K. MEISTER United States Patent HANDLE ASSEMBLY FOR FLUSH TANK William K. Meister, Saline, Mich., assignor to Hoover Ball & Bearing Co., Ann Arbor, Mich., a corporation of Michigan Filed May 27, 1959, ser. No. 816,275

6 Claims. 01. 4-67) The present invention relates to a'toilet flush tank, and more particularly to the construction and arrangement of a handle assembly for usein opening the flush valve of the toilet flushtank. 7

It is an object of the present invention to'provide an assembly'including a handle and tank lever for use in a 'flush tank, said assembly being constructed and arranged so that it can be readily inserted in place in the tank by an operation which is characterized by its simplicity and one which assures a permanent and sturdy mounting of the assembly.

It is another object of the present invention to provide an assembly of the foregoing character which is constructed and arranged so'that it can be manufactured and assembled as a unitary structure and at a relatively.

. a portion of the wall of a flush tank with the handle assemb-ly mounted in place thereon; and

Figure 3 is a fragmentary section taken on the line 3 of Figure 2. V

' Before explaining the present invention in detail, it is to beunder'stood' that the invention is not limited in its application to-the' details of construction and arrangement of parts illustrated in the accompanying drawings, since the'inventi'on is capable of other embodiments and of Also,-

being practiced or carried out in various ways. it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. t r

Referring now to the drawing, the invention will be described in greater detail. The handle assembly comprises the four elements shown in Figure l, which are the handle 10, the sleeve-like part or spud 12, the nut 14 and the tank lever 16. The handle 10 has a conventional lever portion 18 and a cup portion 20 which is designed to enclose and conceal the opening which is formed in the wall of the flush tank with which the handle assembly is adapted to be used. Projecting axially from the cup portion 20 and at aright angle to the lever portion 18 is a rod 22 which has formed in its free end a transverse slot 24. The slot 24 extends substantially deeper into the central portion of the rod 22 than at the peripheral edges of the same so as to form a pair of diametrically opposed shoulder-like formations 26 and 28 in the slottedor cutaway portion of the rod 22. Also projecting from the end of the rod 22 is an axial projection 30, the purpose of'which will presently be described. The handle 10 also has a flange-like element ar C 32 formed in the cup portion 20 which functions to limit the extent to which the handle can be turned in a manner also to be described presently.

The sleeve-like part or spud 12 is a hollow member having an opening 34 therein adapted to fit over the rod 22. The spud 12 is'externally threaded, as can be seen at 36, and has an enlarged annular portion 38 of substantially greater diameter than the threaded portion 36. On the opposite side of the enlarged annular portion 38 from the threaded portion 36 are a pair of circumferentially spaced limit stops 40 and 42 between which the element 32 is adapted to fit when the spud 12 is in its assembled position on the rod 22. By virtue of this arrangement, a limited rotational movement of the handle 10 may be had with respect to the spud'12 so as to provide a small amount of slack movement between the handle 10 and the flush valve (not shown). The spud 12 also has a pair of lugs 44 on the one face of annular portion 38 and an axial extension 46 which projects beyond the end of the threaded portion 36. The purpose of these parts will be described hereinafter.

The tank lever 16 has a relatively long body portion 43 which has a plurality of holes 50 at its one end to which a linkage (not shown) extending to a flush tank discharge valve (not shown) may be connected. The tank lever 16 has at its opposite end'an end portion 52 which is bent at, a right angle to the main body portion 48. The end portion'52 is designed so that it may be connected directly to the rod 22 thereby permitting the handle 10 and the tank lever 16 to function as an integral unit. For this purpose, the end portion 52 has a central tongue 54 of reduced'width so as to provide side abutments 56 and 58. The tongue 54 is shaped and dimensioned so that it will fit into the slot 24 and will extend a substantial distance into the central portion of the slot 24. The end portion 52 is ofsnfiicient width so that the side abutments 56 and 58 will seat on the portions 26 and 28. of the rod 22, thereby limiting the extent to which the end portion 52 can penetrate the slot 24. The end portion 52 also has an aperture 60 therein which is located so that when the tank lever 16 has its end portion 52 inserted into the rod 22 the axial projection 30'of the latter will be adjacent the aperture 60. The handle 10 and the tank lever 16 can then be securely fastened together merely by staking the axial projection 30 into the aperture 60, as can be seen in Figure 2. V

One of the features ofthe present invention is the ease and simplicity with which the described elements can be secured together. In carrying out this assembly operation,'it is only necessary that the spud 12 be fitted over the rod 22 with the limit stops 4!) and 42 passing on opposite sides of the fiangeelement 32-. The free end of the rod 22'will then'project a small distance beyond the end of the threaded portion 36 of the spud 12. The end portion 52 of the tank lever 16 is then inserted into the slot 24 until the side abutments 56 and 53 seat on the slotted portions 26 and 28 of rod 22. The main body portion 48 of the tank lever 16 will be in a direction away from the projection 30 and will overlie the free end of the extension 46 of the spud 12. With the handle 10, spud 12, and tank lever 16 in this position, the axial projection 30 will be staked into the opening 60, thereby locking these three parts together in a rigid unitary structure.

Thereafter, when it is desired to mount the handle assembly in place in the flush tank with which the assembly is adapted to be used, the entire assembly can be secured in place merely by passing the free endof the tank lever 16 through the opening in the tank and'thereafter passing the nut 14 over the free end of the tank lever 16 and threading the nut 14 onto the threaded portion 36 of the spud 12, thereby clamping the wall 62 of the tank between the nut 14 and thmenlarged annular portion 38 of the. spud:12. For a-briefrdescription ot'; thisassembly operation,. attentionv is directed particularly to-Figure 2 wherein a fragmentary portion oiatank wall. 62 can he seen having. anopening, 64 therein for receiving'the handle assembly. As previously stated,.the.tank.1ever,16 can initially be passed through the opening from the lefLside as seen in Figure 2 until. the handle is in the positionillustrated inthis figure. Thereafter, the nut 14 can. be passed. over the end of' thetanklever 16' and screwed ontorthe. threaded portion 36: untiLthe annular enlargement 38 isdrawntightly againstthe'wallt62'. In order. to assure that thethandlewill. always be in its proper position, the lugs 44 are provided to. be received in groovesin theopening 64. so. that the spud 12 cannot turn about its axis.

From the. foregoingit can be seen that a handle assembly has been provided whichcan. be assembled and secured together by a minimum of operations, thereby assuring a low cost item, and atthe same time the construction and arrangement of,the assembly is. such that it will be a rigid unitary structure free from trouble when in:use. The invention is also constructed and. arranged so that itcan be readily andeasilyassembledin place in the. water tank by a of operations; thereby, providing further economy in its installation.
