FLUSH-TANK MECHANISIVL Application filed July 19, 1916.

1 0 oil whom it '7)? m concern Be it known that I, Enwixnn P. Lacey, a citizen of the United States, residing at Zolit'o, in the county of De Soto and State ot l lorida, have invented certain new and use t'ul Improvements in Flusl'i-Tunk Meclnv nisms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to valves for flush tanks and has for an object to provide a new and improved valve wherein the end of a protruding pipe is covered by an improved term of hell with a vent therein for supplying air to the bell under certain conditions.

A. further object of the invention is to pro vide a bell form of valve wherein a tube leads from the top of the bell downwardly, so that when the. bell is in normal or closing position the tube is wholly submerged, and when raised to flushing position the tube serves to admit air to the bell.

With these and other objects in view the invention comprises certain novel features of construction, combination and arrange ment of parts as will be hereinafter more fully described and claimed.

In the drawings Figure 1 is a vertical longitudinal sectional view through a tank showing the improved valve in position.

Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1 showing the balanced relation between the water in the tank and in the trap.

Like characters of reference designate corresponding parts throughout the several news.

The improved valve which forms the sub jcct-matter of this application is adapted to be employed in any usual and ordinary type of flush tank as shown at 10, having a feed pipe 11 and ball valve 12, controlled by the float -3, all in the usual and ordinary manner.

Extending upwardly within the tank is an outlet pipe 14: communicating with a trap 15, the latter discharging at 16 to the utensil to be flushed.

Disposed over the upper end of the pipe 1 is a bell 17 hinged in any approved manner as by employing the bracket 18, and controlled by means of a link 19 connected to Specification of Letters Patent.

Patented May 8, 191%.

SeriaI No. 110,124.

a lever 20 carried upon the rock-shaft 21, and externally controlled in any approved manner as by the handle 22.

The side of the bell 17 opposite the hinge 18 is provided with a sleeve 23 into which is inserted a nipple 94. open at both ends. The position and relation oi. the sleeve 52?; and nipple 2% are such that the nipple inclines downwardly to a point approximating the bottom of the bell 17. Into the upper side of the nipple 24: is secured a short piece of small tubing bent to substantially right angles as shown more partici'ilarly at Fig. 1. so that the outer or upper end of such small tubing 25 extends a considerable distance above the opening in the outer end 01 the nipple 24.

In operation, with the parts located as.

shown at full lines in Fig. 1, the water will be introduced into the tank, rising within the bell. 17 until the air in the bell 1T vtorces the water in the trap 15 to such a position as to exactly balance the water column above the top of the water within the bell and to the top of the water in the tank. In other words, the water column indicated by C at Fig. 1 will exactly equal the water column indicated by C at Fig. 2.

The several parts will be so adjustedthat the column C at Fig. 1 will start from ad-v j acent the top of the pipe 1 1 and extend to the top of the water in the tank when the flow of water through the feed pipe 11 has been stopped by raising the float 13. At this position the two columns C and C are exactly balanced.

When, however, the bell 17 is raised by manipulating the handle 22, water will flow down the pipe 14: and. the column will then be the height from the top of the water in the tank to the overflow of the trap, and will force the trapped water into the flushing receptacle.

hen the hell 1'? is raised to dotted line position, the water will first flow througl'i. the nipple 24% to supply the space occupied by the air within the bell, but as the bell is only momentarily raised and is dropped back to position action is continued by the siphoning action of the column of water drawing the water in the tank upwardly through the bell and down through the pipe 142 until the Water has extended below the level of the nipple 24, when air admitted to the bell 17 will enter the pipe 14- bet'ore the water has dropped entirely below the lower edge of the bell, and the water contained in the trap 15 will remain therein. As the water fills up from the feed pipe 11 the end of the nipple 2a is first covered, but as the inner end of the vent 25 is higher than the outer end of the nipple 2% air is still admitted through that pipe until the water reaches the top of the tube 25, when further ingress into the bell 17 is interrupted.

I claim 1. A flush tank mechanism comprising in combination with a tank, a pipe extending upwardly in the tank and having an open upper end, a bell covering -the open upper end of the pipe and hinged to swing, a nipple communicating with the upper end of the bell and extending downward and open at both ends, a vent tube leading from the nipple to a point within the tank below the normal water line and above the lower end of the nipple and means to raise the bell upon its hinge.

2. A l'lush tank mechanism comprising in combination with a flush tank, a pipe extending upwardly within the tank and having an open upper end, a bell over said pipe, a nipple communicating with the upper end of the bell and extending diagonally downward to a point adjacent the bottom of the bell and having an open outer end, and a bent tube occupying a small portion of the nipple and having its opposite ends above the uppermost portion of the open outer end of the nipple.

3. A flush tank mechanism comprising in combination with a flush tank, a pipe extending upwardly into the tank and having an open upper end, a bell covering the pipe, a nipple communicating with the upper end of the bell and extending diagonally down-- ward to a point adjacent the bottom of the bell, a bent tube inserted in the lower end of the nipple and having its opposite ends above the uppermost open portion of the nipple, and means to raise the bell until the nipple and tube extend above the bell.

In testimony whereof I ailix my signature.
