FLUSE-VALVE-OPERATING MECHAFISM.

' Application filed July 8,

r This invention relates to fiush valve operatingmechanisin, designed particularly for use in connection with china flush tanks, and "has for itsobject to provide a novel form of sleeve for mounting in the usual opening in the wall of the tank, 1 whereby the entire mechanism may, bereadily, quickly, and rig-idly clamped to the wall, by means of a single threaded member; A further ob ect is to provide a novelarrangement of the china operating parts whereby the handle and escutcheon comprise a single part and 1 whereby the operating shaft be permanently secured to the china member and may lee-insertedinwardly through the sleeve, and detachably connected to a crank member that actuates thevalve lift, by simple clinching means. And a'further object is to generally improve and simplify the mechanism, to the end that fewer parts, and less time, labor and expensive operations are required, for manufacturing, assembling and applying 7 the said mechanism, than heretofore.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying drawing, in which- Figure 1 is a top end View of a flush tank with the cover removed. Fig. 2 is a broken side elevation of the same. Fig. 3 is a broken end elevation of the tank. Fig. 4 is a hori- .zonal section, taken on'line 44 of F ig. 2. .Fig. 5 is a view of the handle shaft. And Fig. 6 is respectively an end and a side view of the crank member carried by the handle shaft.

In the drawing, 2 represents a china flush tank, which may be supplied with the flushing Water by a pipe 8, the water being delivered by said pipe to a ball-cock 4, and the latter being controlled by the usual float 5. The discharge of the water for flushing purposes is effected by an ordinary valve 6, which controls the usual bottom outlet (not shown). The valve 6 islifted away from its seat by a rod 6, whose upper end connects with one end of a rockable lever 7 as shown in Figsl, 3 and 4. The opposite end of the lever 7 is formed witha crank-portion 7. The V lever 7 is operatively supported by similar'spaced perforated lugs 8, which may be integral parts of a bracket 8, the latter being mounted horizontally on the inner front wall of the tank 2. The bracket 8 is formed with a flange-hub 8 which loosely engages a molded opening 2 of the tank,

largement 9' which substantially fills the I opening 2 adjacent the said flange, like the hub 8. I Beyond the enlargement 9 the barrel of the sleeve is preferably externally threaded, as at 9*. This threaded portion passes through the hubS of the bracket and its projecting inner end is fitted with a nut 10, which engages the bracket, and together with the sleeve provides the sole means for clamping the valve operating mechanism to the tank. The sleeve 9 has a smooth bore,

in which is loosely journaled a shaft or rod 12, by which the lever 7 is rocked'for opening the fiush valve 6. The shaft 12 projects beyond the opposite ends of the sleeve 9, its inner end preferably being square and split, as at 12, and upon this split portion is mounted a crank member 13, as best shown in Figs. 4 and 5. One arm of the crank 13 is formed with a loop or eye 13, the opening of the latter being preferably square to conform to the shaft. The other arm of the member 13 extends rearwardly beneath the crank portions 7 of the lift rod. The outer end 12 of shaft 12 is also shown square, and this portion is preferably permanently embedded in a molded socket 14 of a china member 14, the latter combining in one part an escutcheon 14, an ornamental spherical portion 14", and a pending handle 14", by which the shaft 12 and crank 13 are rocked for opening the valve 6. The square portion 12 may be secured in the socket 14 by any suitable cement, as litharge, or the like. The escutcheon 14 is preferably formed with a central cavity or recess 14 which receives and conceals the flange 9 of the sleeve. The flange 9 and the recess 14 are preferably so constructed that when the device is assembled, as shown in Fig. 4, the part 14" is held clear of and may rotate freely Without touching or chafing the tank 2.

To apply my device to atank, the barrel of the sleeve 9 is preferably first inserted inwardly through the opening 2 of the I so ' I mounting and holding the mechanism in .place, and bylnoldingthe escutcheon, knob,

tank, the bracket 8 is next placed in position against the inner side of the tank with the 1 hub Siloosely telescoping the said opening and the threaded portion 9 of the sleeve.

The nut 10 is then screwed on to the sleeve and tightened up for rigidly clamping the flange 9 and the bracket 8, to the wall of the tank. The shaft 12 which ispreferahly' first permanently secured to the'chinapart 14;, is next inserted inwardly through the sleeve until its. split inner end projects beyond the corresponding end of the sleeve.

* The'crank member 18 isthen applied and Y the split portionof the shaft is spread and clinched against the outer face of the loop 13", for holding the shaft and related parts in plac'e,-.as shown in Figs. 3 and 4. The

squaro portion 12 is preferably slightly reduced' in order to* provide awshoulder I against which the inner face ofthe loop 13 seats, as shown in igs. 4 and 5.. The shaft 12 andthe member 14 maybe readily and I. quickly removed by simply unclinching the split end'ofthe shaft.

, My flush valve operating mechanism is extremely simple, has but few parts, and

. require's fbut little machine work in order to prepare the parts for use. By construct:

' ing the parts as herein shown and described,

but one threaded connection is required for ing in said wall of the tank, a sleeve having aded end extending through the bracket .and its hub, an integral flange on .the opposite end of the sleeve engageable with the opposite'side face of said tank wall and having a hub of reduced diameter extending partly within the opposite end of V the opening, the innerends of the hubsbeing spaced so asto leave free space between the part of the: sleeve between thehub and the wall defining the said transverse opening in the tank, a shaft. extending through a sleeve, a handle on the opposite end ofthe '7 shaft having an 'escntcheon extending over the flange and in encircling relation to the l I periphery thereof, a nut on the threaded end of the sleeve engageable with the bracket, and a crank-on the other'end of'the shaft. I 2. In a flush valve operating mechanism,

a sleeve formed to extend through a perforation in a tank wall and having an inte as gral flange on one of its ends formed with aninward'ly, projecting hub, the flange bei engageable with one face of the tank- W26 and the hubbeing engageable in the wall;v perforation, a lever supporting bracket 10' engage'able with the opposite face of the tank wall and perforated. to receive the,

oppositeend of the sleeve and having a hub engaging the vwall defining the perforation said hubs having, their inner ends Spaced.

apart and conjointly acting to hold thercenu te'r of the; sleeve spaced from the wall defining the perforation, means on the said opposite end of the sleeve to hold the bracket against said opposite face of the tank wall, a shaft extending through the: f;

sleeve, a handle on one end of the shaft and a crank on the other end ofthe shaft. v

In testimony whereof-I afiix mysignatur'e,

HARRY DE WALLACE.
