v 1927. Serial This invention relates to flush tanks and 1s a division of my copendmg appl cation,

Such refill tubes constitute a source of noise which is occasioned by the friction of the water passing therethrough under varymg pressures. In addition, these tubes as ordinarily constructed 1 constitute a source of waste in that a surplus of water is supplied to the bowl and accordingly wasted.

An object of this invention isto provide a flush tank of such construction and arrangement that the amount of water passing through the afterfill or refill tube can be elements removed.

accurately controlled so as to eliminate the friction noises and prevent waste.

This and other objects whichwill be obvious to those skilled in this particular art are accomplished bymeans of the invention illus-. trated in the accompanying drawings in which Figure 1 is a transverse sectional view througha fiush tank provided with one form of this invention. Fig. 2 is a view of a part of the control valve chamber illustrating the manner of connecting the refill tube. thereto I and Fig.3 is a transverse section on the line 3-3 of Fig. 1 with certain of the operating The particular embodiment of this invention which has been chosen for the purposes of illustration is shown in conjunction with an ordinary flush tank 5 having awate'r sup ply control valve, within the valve chamber 6, adapted to be automatically operated by the usual float 7 and associated mechanism. A refill tube extends from the valve chamber into the usual overflow tube 21. Hitherto these refill tubes were provided with threaded ends which were attached to the valve chamber by being threaded into a suitable opening formed therein. The formation of threads upon the refill tube, which is of comparatively small gauge materially weakened it at that point with the resultthat in assembling the structureja large loss was sustained through breakage of the refill tubes at their point of connection with the valve chamber. In order to form a more 16,644. Divided and this application filed. June BO. o. 202,720.

rugged construction and atthe, same time i provide a device which is more easily and rapidly assembled, I provide a swivel nut 22 i i I which is n on the end or the lean tube bv afiange 23 preferably formedon the end'o t the tube. The valve chamberisprovided with a bore 2a extending through the wall thereof and through a lug-'25 formedf-onthe vided with threads for engagement withthe swivel or coupling nut22 bymeans of which the refill tube is connected'to the valve chamber. Such a construction provides a rugged structure and enables the refill tube" to be rigidly connected to the valve housing in! any adjusted position Without being -sub-. gected to any detrimentalstrain.

The present invention also contemplates the reduction of noise caused by the friction of water-passing through the refill by con.- 1 v i 6!) outside 01'? the valvexchamber wall and pro-.

As illustrated, this is accomplished by meansoli' a set screw 26 threaded in a bore 27 communicating with i the opening 24 leading from the valve cham ber to the refilltube. A lock nut 28 is provided for locking the water controlling screw 1n set position. By properly positioning the regulating screw 26 the amount of water fiowingthrough the refill tube can beaconrately controlled so that no surplus will; pass through to the bowl. In addition, the rate 1 ot flow through the tube can be so accurately controlled as to eliminate the friction. noises which have hitherto also been present. What I claim as new anddesire tosecure by Letters Patent is:

In testimony whereof, I have hereunto set my hand this 24th day of J 1.1118 1 927.
