concern.' l Be it knownV that I, DAVID G. DE Miur, residing at Tampa, in the county of'Hillsborough and State of Florida, have invented certain new and useful Improvements in Ball-Cocks, of which the'following is a specification, referdrawings.

This invention relates to ball cocks, and more particularl v to an eicient valve mechanism for flushing tanks.

The object of my invention is to simplify v a valve device or ball cock, yegadproduce a highly efficient and positivey m anism which will give a great amount of satisfaction' and will last a'. long time.

invention consists' of .certain novel construcclained. l

and aivotally mounted at 11, in the aperture 12 o the frame 6, is a weighted catch 13,t'hat has its inner end 14 normally overhanging the annular flange 10, so that if the lever arm 15 should become detached, at 16, from the parallel lugs 17, integral with the closed top of the lunger casing 9, the catch 13 will by the annular flange 10 and prevent 'any y great a flow of water through the auxiliary extension 7 and thence around the passage fhrmed by the spiral or .threaded portion 8 o'n the outer face ofvauxiliary extension 7. Between the closed to of plunger casin 9 cip the auxiliary hol ow extension is placed the washer 17, which produces a tight closure, ordinary. risen in tank 1 to cause the'rod 18 to assume' al horizontal position, a very tight closure is leakage or seepage out of pipe 7 after the water has risen to itsA predetermined level in the tank. To permit a tight closure of pIunger casing 9 upon the hollow extension ,I arrange a vent pipe 19 in the tank 1 having the lower end of pipe 19, at 20, threaded into tureformed in the plunger 'casing 9 near the top, so as to vent the interior of the plunger tension 7 to its normal Fig. 1.

The lever arm 15vis seated position,

pivotally mounted, by upon the parallel extensions ,22 formed at the upper end of frame 6. Further, I use cotter pins for all of the connections, `hotter pin 23 being positioned in registering apertures in the parallel ears inte al with the clamping l body 25 surrounds the ball float carrylngirod 18, by formin on the H oat carrying ro 18, a plurality `o cotterpin receiving notches 26, which notchesl register with the apertures in the aral el ears 24; when the cotter pin 23 is p aced in these apertures end registering notches, fixed position,
