JOSEPH W. NETI-IERY, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE NETI-IERY HYDRAULIC VALVE COMPANY, OF INDIANAPOLIS, INDI- ANA, A CORPORATION OF NEW JERSEY.
FLUSHeTANK-SUPPLY SYSTEM.
SPECIFICATION forming part of Letters Patent N0. 741,818, dated October 20, 1903.
v Application iiled October ll, 1902. Serial No. 126,829. (No model.)
'To all whom, it may concern.-
Beit known that I, JOSEPH W. NETHERY, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and4 useful Improvements in Flush-Tank-Supply Systems, of which the following is a specification.
The object of my present invention is tov preserve in closed iiushing-tanks the requisite supply of air to insure the advantages incident to the use of an air-cushion in connecwill be automatically replenished.
Referring to the accompanying drawings, which are made a part hereof, and on which similar reference-characters indicate similar parts, Figure 1 is an elevation of a iiush-tank Water-supply system embodying my invention as the same appears when used in connection with an ordinary water-closet; and Fig. 2 is a central sectional View through the pipes and valves and the immediately-adjacent fragment ofthe tank which particularly illustrates my present invention.
The tank 10 is shown as an ordinary cylindrical or boiler-shaped tank. rlhe water-supply pipe 11 may enter at any suitable point, but usually from the bottom, and this pipe should have near the point of entrance an angle-valVe 12. The iush-pipe 13 leads from the bottom of the tank to the article to be flushed, as thewater-closet 111, andthe flushing-valve 15 is set in at a proper point. This flushingvalve is the subject of other patents and applications for patents, and not being peculiar to my present invention will not be illustrated in detail or further described.
In illustrating my invention I have shown a vertical pipe 16, positioned alongside the be effective for the designed purpose.
The operation is produced by means of the valve 15, which when opened permits the water to be discharged from the tank 10 into the closet 14, which it iushes in the ordinaryv manner. The system is so arranged that when the water is discharged the valve will close and the tank will rell. After numerous uses, however, the action is such that the air will be largely absorbed by the water .and too small a quantity will remain in the tank to By this time the pull of the water in passing out through the pipe 13 will have asiphoning action in respect to that contained in the pipe 16 and will draw it into the tank 10, leaving said pipe 16 free of the small quantity of water usually contained therein and which forms a Water seal for the check-valve 19 and at the same time holds said check-valve 19 open, so that air will be sucked intherethrough and will pass into the tank, thus replenishing the tank with its proper and designed supply of air. This operation will be repeated as often as the air becomes exhausted to too great an extent, and thus the proper quantity of air will be continuously automatically maintained.
I have shown below the check-valve 19 a small drip-pan 20, with a waste-pipe 21 lead ing therefrom to carry off any small amount of water which may be discharged at the time the check-valve 19 is opened by the Siphoning action, as above described.
Having thus fully described my said invention, what I claim asnew, and desire to secure by Letters Patent, is-
1. The combination, in a flushing system, of a hush-tank, a ushi'ng-pipe leading therefrom, a suitable valve thereto, a supply-pipe to said tank, a pipe extending vertically past said tank and connected thereto by two branches one at the top and the other at the bottom and extending alittle distance below said tank, and a check-Valve on the lower end of said pipe.
2. The combination, in a flushing system,
of a flush-tank, a flushing-pipe leading therefrom, a suitable Valve to said flushing-pipe, a supply-pipe to said tank, a pipe extending from a point below said ushing-tank up to
