FLUSH-TANK FITTING.

Application filed September 4, 1926. Serial No. 133,564.

Fig, 1 is a broken plan viewof my improved revoluble-handle flush-tank fitting shown as applied to the front wall of a tank;

Fig. 2 is a broken view of the fitting in inside elevation; and i Fig. 3 is a vertical sectional view of the fitting on the line 33 of Fig. 1.

My invention relates to a revoluble-handle flush-tank fitting, the object being to produce a simple, durable and dependable fitting of the character described, constructed with particular re 'erence to the avoidance of dead centers, when thehandle 15 111 a vertical plane and thus to minlmize tile chance of thevalvelifting lever being stalled inits elevated posi tion, in whichthe valve is prevented from returning to its closed position upon its seat in the tank.

, With these ends in view, my invention con sists in a revoluble-handle flush-tank fitting having certain details of construction as will be hereinafter described and pointed out in the claim.

In carrying out my invention, as herein shown, the inner end of the valve-lifting lever 5 is turned downward to form an inclined movement of the handle without disturbing the said lever.

Under this construction, when the said handle 11 is swung in either direction, the rounded face 8 of the eccentric 9 engages with the inclined upper edge? of the lifting-arm 6 of the lever, with the effect of lifting the outer end of the lever and hence the valve (not shown) from its seat in the tank.

When the user lets goof the handle, gravity will return it into its normal, depending position in the vertical plane, in which the eccentric 8 is clear of the edge 7 of the arm (3 of the lever, so that the factor of dead centers, when the handle is in a vertical plane is eliminated, and, consequently, there is prac-' tically no chance of the leverbeing stalled in its raised position, in which the'valveis not permitted to move into its closed position.

As shown, the valve-lifting lever 5 is hung upon astud 13,carried by a bracket-arm 14 mounted upon an externally-threaded assemly-sleeve 15, which provides abearing for the shaft 10 aforesaid, and is mounted, as

usual, in the front 16 of the tank, its threaded outer end receiving a nut 17 by which a washer 18 is brought to a firm bearing upon the outer face of the front of the tank, whereby variationsv in the thickness of the said wall are provided for.

A lug 19, formed upon the bracket-arm 14 at a point below the stud 13 carried thereby, limits the downward movement of the outer end of the lever and hence prevents the upper edge 7 of the lifting-arm of the lever from acting as a stop, the said inclined edge of the arm being thus always held out of engage;

ment with the eccentric 9, save when the same is operated by turning the handle 11 in one direction or the other.

I claim: 1 Y

In a revoluble-handle flush-tank fitting", the combination with a valve-lifting lever, the inner endof which is provided with a downwardly-inclined o )erating-surface, of a handle-shaft, a handle located at the outer end thereof, and an eccentric positioned upon the inner end thereof atan acute angle with respect to the handle and so asto normally occupy a plane parallel with the said operatingsurface when the handle is depending in the vertical plane, whereby the weight of the handle and eccentric act in unison to move the said eccentric from a dead-center position with respect to the said operating-surface.

In testimony whereof, I have-signed this specification.

ARTHUR W. TVELLINGTON. I
