FLUSHlNG-TANK.

SPECIFICATION forming part of Letters Patent No. 515,521, dated February 27, 1894. Application filed March 13. 1893. Serial No.465.804. (Ne model.)

.To all whom it may concern:

Be it known that we, JOHN R. DONNELLY and CHARLES F. BARTON, citizens of the United States, residing et Feirfield, in the ounty of Soncrset and State of Maine, have invented certain new and useful Improvements in Flushing-Tanks: and we (lo 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 eppertains to make and use the same.

Our invention reletes to e finsh tenk of that class which intermittently fills and discherges when fed by e continuous stream of water.

The object of the invention is to devise e tenk which will be especially edepted to the use of photographers for washing prints, &(3., and the aim is to constructa tenk which will internittently discharge the entire contents of the tenk and which will fill each time to any desired height.

W'e illustrete our invention in the accounpenying drawings in whichl 'igure l is a vertical section througha tenk constructed according to our invention and Fig. 2 is e plan or top View. Fig. 3 is a perspective View of a detail.

A represents a tenk of eny suitable construction; it ney be supported on legs or brackets or in any desired location according to the use to which it is to be put.

B is the water supply pipe and C is the Weste pipo which extends Verticelly through the bottom. lVithin the weste pipe O fits the tube D. The fit must be somewhat loose so that the tube will slide easily up and down within the weste pipe. On the top of the tube D is an open topped float d. e prefer to use a floet such es here shown consisting of a flat disk with e rim or fiange around its edge and made as shallow as possible consistent with buoyancy. It must be somewhet more then sufficiently buoyent when resting on the water, to lift the tube D. The float d when down rests ina recess a; whichisforrned in the bottom of the tenk around the upper end of the waste pipo C. The rim of the fioat should be below or' et the level of the bottom of the tenk so as to drein off all the water when the tenk discharges.

In order to allow the water to get under the fioet to lift it, it rests when down on pins a' in the bottom of the recess a. Means are provided to limit the upward motion of the floet and for this purpose we prefer to meke use of a ring ewhich is held centrally in line with and above the tube atany desired height by means of a bent rod f which is edjustably secured in a lug h by means of a set screw g.

The operation of our tenk is as follows- When the water comes i u it first gets under the floet d filling the recess a and the buoyency of the fioat lifts the tubeD in the weste pipe. As the water rises, the float end tube rise, the weste pipe being all the time closed by the tube. When the fioat reaches the ring e which is setat the point to which it is desired to fill the tenk, the lower edge of the ring surrounds the opening in the upper end of the tube and arrests the notion of the float. The water continues to rise and overflows the rim of the oet filling it and causing it to sink. The water which first overfiows into the fioatis prevented from running down through the tube, the opening of which is closed by the ring e, so that the filling of the floet is assured however small the stream which is flowing through the inlet pipe. The water immediately begins to discharge through the top of the tube, passing down through the waste pipe and so on until it is entirely dreined froni the tenk the fact that the floet is entirely below the surface of the bottom allowing all the water to discherge es already pointed out. All the water being discherged from the tenk and the fioat being within the recess a, the water continues to ,overflow into the fioat in a Volume equal to what is running into the tenk but the body ot water under the fioet is sufiicient to lift it even with e little water inside. The tube is egein drawn upwerd and the tenk again discharges and so on internittently. If the tube when et its highest position sticks and refuses to settle when the float is full, the water simply continues to rise and overfiow into the ring e and thence down the tube so that the tenk een never overflow unless the tube' gets clogged.

We claiml.` The herein described ushing tankheving a weste pipe, a tube fitting therein and ICQ having on its upper end an open topped float for lifting said tube, and a ring Suspended in the tank above said tube and axially in line with the same for checking its Upward Inoton the lower edge of said ring being adapt ed to form a tight joint with the surface of sa d float the thiekness of said ring being sufficent to allow the fioat to fill before the water runs over its upper edge, substantially as described.

2. The herein described flushing tank havmg a waste pipe, a tube fitting thei-ein and having on its upper end an open topped float for lifting said tube, a ring centrally above said tube and axially in line therewith, the
