ATTORNEY Patented Sept. 24, 1929 PATENT OFFICE HERBERT B. MYERS, OF LITTLE ROCK, ARKANSAS FLUSH LEVER Application filed October 61, 1927. Serial No. 230,066.

This invention relates to the construction of an improved flush lever assembly for closet tanks.

Other objects and advantages of the in-.

vention will be apparent from the following detailed description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a longitudinal cross section of a flush tank equipped with my invention,

Figure 2 is a cross section thereof,

Figure 3 is a horizontal cross section taken on the line 33 of Fig. 1, I

Figure 4 is an enlarged detail of the lever operating. mechanism,

Figure 5 is a fragmentary detail plan view,

Figure 6 is a perspective view of the valve operating assembly,

Figure 7 is a detail perspective of the wiper roller, and

Figure 8 is a detail perspective of the op erating lever.

There is illustrated a tank l'o'f usual construction having an operating lever 2 carrying a pintle 3. The pintle 3 is supported in a bearing 4, the bearing in the present instance comprising a sleeve 5 externally threaded and disposed through a suitable opening in the tank 1. An arm 7 having a squared hollow portion 8 is arranged about the sleeve 5 and adapted to fit into a corresponding opening 9 of the tank wall 10. A lock nut 11 is adapted to be screwed upon the threaded sleeve 5,

thus aifording a tight and rigid support. A furcated lever 12 is fixed to the pintle 3 in any suitable manner, but in the present instance is shown secured by a cotter pin 13. The outer extremities of the furcations of the lever 12 are provided with a pintle 14; carrying wiper rollers 15. The arm 7 is provided with a bracket mounting 16. The lever 17 is pivoially secured to the bracket 16, as shown at 1 a It will be noted, that by the arrangement shown in Fig. 2, the mounting of the bracket 17 with respect to the support 16 is nearer one end, thus providing a short lever and a long lever, the short lever portion carrying at its extremity a pintle 19 on which is mounted a roller 20. This roller is of substantial size, adapted to co-act with the rollers on the furcated lever. The opposite end of the lever 17 is provided with a series of, openings 21, providing a means whereby adjustment may be had with the ball valve, as will be hereinafter explained. I

A lift wire 22 is arranged in one of the openings 21 extending downwardly and being formed at its lower portion 23 with a curved portion 24 adapted to be engaged by a valve stem 25 of a valve 26. An'overflow pipe 27 is provided, this being of the usual form. On the overflow. pipe I provide a 001- lar 28 adjustably arranged for vertical adjustment. A guide bracket 29 is associated with the collar 28. The bracket is provided with extensions 30 at top and bottom, these. extensions being adapted to receive the valve stem 25 slidably therethrough.

Mounted upon the valve stem 25 I rovide an adjustable collar 31 which, as may e seen from consideration of Fig. 6, is adjustable upon the valve stem. The collar 31 is dis- 35 posed above the bight portion 24, and therefore, it will be seen that the lift of the ball 26 may be readily varied by adjustment of the collar 31 upon the stem 25.

It will be apparent that I have provided a double valve guide which permits accurate seating of the ball valve, and further, permits ready removal and replacement of the parts, as occasion arises, without dismantling the flush lever mechanism.

As best seen in Fig. 1, the wheel 20 is mounted eccentrically with respect to the furcated lever, and has rolling contact with the rollers 15, this affording a smooth cam like action.

The operation When the lever 2 is moved in either direction it causes one of the furcated pintles to roll against the Wheel 20 making an instant and positive lift to the lever 17 which in turn raises the lift wire 22 the bight portion 24 of which is brought into engagement with the collar 31 on the stem 25, this action raising the ball valve 26 away from its seat, thereby permitting the water within the tank to flow outwardly thus flushing the closet.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subj oined claims.

I claim 1. In an apparatus of the character described, a tank, an outlet, a valve therefor, said valve having a stem, an overflow pipe, a guide bracket vertically adjustable upon said pipe and having spaced guide bearings for said stem, an adjustable collar on said stem and disposed between said bearings, an operating means on one wall of said tank, and a lift wire connecting said operating means and said valve stem below said collar.

2. In an apparatus of the character described, a tank, an outlet, a valve therefor, said valve having a stem, an overflow pipe,

. a vertically adjustable collar carried by said pipe and having a bracket, said bracket comprising laterally extending arms roviding spaced bearings for said stem, a ongitudinally adjustable collar on said stem, an operating means mounted upon one wall of said tank, and a lift wire connected to said 0 erating means, the lower end thereof being ent to form a bight portion for engagement around said stem and beneath said collar.

Signed at Little Rock in the county of Pulaski and State of Arkansas this 26th day of October A. D. nineteen hundred twentyseven.

HERBERT B. MYERS.
