ATTORNEY 1.2 326 r e ntanc filed Apr-ni 'rtesammviwesternerse"MECHANISM;

To all whom mq iwacemzi Be it known that FITHS, a citizen of the United States, and a resident oi? Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new anduset'ul Improvements in Flush-Tank-Valve-Actuating Mechanism, of which the following is a specification.

My invention has for its object to simplify the construction of mechanism for operating the valve of a flush tank for controlling the flushing action of the latter and it consists in the combination and arrangement of parts as hereinafter more fully described and particularly set forth in the claim.

In the accompanying drawing 1 have illustrated one form of a convenient embodiment of my invention but it will be understood that changes in the details of construction within the scope of the claim may be made without departing from my invention.

In the drawings:-Figure 'l is a view partly in front elevation and partly in section; and Fig. 2 's a view showing a part of the flush tank in-transverse section and certain of the operating mechanism in elevation.

Referring to the drawings, 1 designates a water closet bowl support/ed upon a tioor or other support '2 and 3 designates a soil pipe.

4: designates a pipe for supplying water to the flush tank 6 designates a flush pipe for conveying water from the tank 5 to the upper part of the bowl 1 for flushing and cleansing the same. The upper end of the pipe 6 coinmunicates with the lower end of one of the legs of a siphon 7. The longer leg oi? the siphon is provided with a port 8 closed by a valve 9 pivoted at 10v For the purpose of opening the valve 9 l have provided a rod or bar 12 which extends across the flush tank 5 in the inannerquite clearly shown in Fig. 2 of the drawings which rod is pivotally mounted in hearings on the walls of said tank as shown at 13 and 14. The rod is provided with an offset or crank portion 15 to which the upper end of a link connection 16 is connected, the lower end thereof being connected at 1'? to the valve 9. One end of the operating rod or bar 12 extends beyond the side of the ilush Gnirrrrns, or riainnnnnrnia,"rnNnsYLvAnis" Specification ofgietters flatent."

androtated in either direction. In the normal position of the parts the handle 20 preferably projects downwardly in the manner shown in full lines in Fig. 1 while the crank portion 15 of the said rod extends in a direction toward the point of connection of.

the link 16 with the valve 9 at 17 so that the said crank and link connection 16 are in substantial alinement as is shown in the full and dotted lines in Fig. 1 of the drawings.

\Vhen the handle 20 is turned in either ditank i'isprovidedwvith a handle 20 by means of which the rod .12 n ayc ber turned 9 and link 16 being also shown in dotted lines. The valve may be turned toward the right if desired and in either case may be to make a complete revolution, the rod or bar and its crank also making a complete revolution. It is not necessary, however, that the handle and rod or bar be turned completely around.

l Vhen the valve is opened the water rushes through the port or opening 8 and starts siphonic action so that when the valve 9 closes the water continues to flow through the siphon and through the flush pipeifi to the bowl 1 in known manner. As the water; in the tank 5 empties therefrom the ball float 2i iiloves downwardly with the water to per: 22 to perrhit water to How from theusupply pipe 4 into the tank 5.

When the water has been discharged through the siphon 7 from the'tank 5 the siphonic action is broken so that the tank iimnediately begins to fill by reason of the water flowing thereinto from the discharge opening 23 from the supply pipe 4. It continues to fill until the float ball 21 has been raised to a height sui'liciontto cause the cam 24'. upon the inner end of the lever 25 supporting the said ball to act ripen the valve 22 to close the same and thus prevent further flow of the water from the pipe i into the tank 5.

it will be seen that applicant has provided a very simple construction. of means for operating the valve 9 and that such nornmiiy 'rneans contains very few parts with the result that there little likelihood of the mechanism. a/ing ou; of order and needing ttepnilz oiaiin:---

means for rotating said member in eithei' direction for opening the said valve.

In testimony that I. claim the foregoin as my invention, i have hereunto signed name this fourth day of April, A. D. 19141.
