PLUMBING SYSTEM v Original Filed Dec. 19, 1953 2 Sheets-Sheet 2 IJI I v v ITIJQTIIEI: 44 v W (4.
Patented Oct. 6, 1936 UNITED STATES PATENT OFFICE PLUMBING SYSTEM Application December 19, 1933, Serial No. 703,094 Renewed December 30, 1935 8 Claims. (01'. 4-70 My invention is concerned with plumbing sys-' tems, and more-especially with such a system where a vacuum breaker, so-called, is used for the prevention of back siphonage through flush valves used on water-closet bowls, bed-panclosets, bidets, bed-pan washers, slop sinks and any other type of fixture that'flush valves may be used on, or on any sterilizingtank or receptacle. where the supply pipe or hose is submerged in the water level is above the holes in the rim of the bowl. It will also occur on side spud closet bowls where the closet spud is partially or completely submerged in the water seal, which is the normal water level in the closet bowl. When back siphon- 5 age occurs, it pollutes the water in the supply line. In carrying out my invention in the preierred form shown herein, and where it is used in connection with a flush valve, I employ as a part of the conduit connecting the supply line with the 3g receptacle which may be siphoned, a pipe connecting the bottom of the flush valve with the bowl, in whichpipe is an aperture protected by means in the pipe so that it permits the downward passage of the water from the supply pipe 35 through the flush valve and down through the pipe without the p ssibility of any of it escaping through the aperture, while said means permits the air to enter freely through the aperture-in case a vacuum occurs in the supply, and thus 40 prevents the possibility of the contents of the bowl being sucked back into the supply pipe,
thereby possibly contaminating its contents.
To illustrate my invention, I annex hereto two sheets of drawings, in which the same reference 45 characters are used to designate identical parts in all the figures, of which,-
Fig. l is a vertical section through one type of a flush valve having my invention applied thereto and specifically designed for use with the blow-.
50 out type of closet bowl;
Fig. 2 is a similar view of a vacuum breaker of the type shown in Fig. 1, but one where it is designed for all other type closet bowls and slop sinks; and
55 Fig. 3 is a view of my vacuum breaker of the type shown in Figs. 1 and 2 as applied to the flush tank of. the water-closet.
In Fig. l, I have shown a common type of flush valve ill with its connection ii to a supply pipe,
-not shown, and with a connection pipe H which 5 opens in the customary manner to the top of the ordinary closet bowl, not shown. With this type of flush valve, in case a vacuum occurs in the supply pipe, the vacuum extends through the connection II, the chamber I3 in the valve below the diaphragm it, through the passage IS in the lower half l6 of the valve casing, and through the passage ii in the upper half ll of the valve casing, and down through the self-cleansing regulating valve ii to the upper chamber ilhwhere the vacuum will tilt the relief valve II, as. indicated by its position, and then past the relief-valve seat 22, and on down through the discharge passage 23, through the connection tube l2, and thence to the closet bowl, not shown, from which it will siphon its contents under the conditions above noted it no vacuum breaker is employed.
In the form shown in Fig. 1 the connection member or tube i2 has at its upper end the horizontal flange 24 by which it' is held against the 25 annular bottom of the valve casing I8 by the connecting sleeve 25 screwed on to said bottom.
I secure in the top of the connection tube, and filling it, the water inlet member or tube 38, which has the tapered portion 31 preferably located in the horizontal plane of the air inlet apertures 34,
and preferably terminating in the reduced straight portion 3!, which forms a nozzle cooperating with the water outlet port of the connection member which is preferably formed by the preferably 35 slightly flared smaller end 39 of the flaring tube 40, which has its large straight lower end I secured in the connection tube i2, as shown. with this construction, the water during the flushing operation passes down through the nozzle 38 and 40 through the flaring tube 40 to'the bowl without the possibility of any of the water reaching the apertures 34 provided in the connection tube l2 and preferably protected by a hood 35 formed on the bottom of the connecting sleeve 25. when the vacuum occurs, the air, as indicated by the arrows, will enter the apertures 34 and pass through the annular channel 42 between the end I! of the flaring tube ill and the end of the nozzle 38, and pass up through the flush valve .to the supply pipe, eflectually breaking the vacuum. In Fig. i this arrangement is shown with the nozzle 3| and the end of the flaring tube 40 of the proper size to be used with the blow-out type of closet bowl, where only a small passage for the water is needed. 58
" the discharge outlet :5 to the closet.
Naturally the action of this Venturi tube arrangement is to draw some air into the connection memher through the inlets 86 and carry it down with the water through the outlet lll during the flush lug operation.
In Rig. 2, I illustrate the hut proportioned dlflereutly, oh the lerger passage lectured s pressure used in other type closet loo ls slop slicks.
Flg. 3, I have shown my tnveutlou spelled to e. motes-closet tank: et, in which s, connection St to the supply pipe, not shown, has secured thereto on the interior of the t exteuslol. Q5 of the supply pipe, con uteri. to valve casing 46 homing the 1 5? lo? the valve :38, which has the connection shown to the fleet hell $9, so that when the Waste? aches d, c this type of flushing eppemtus, cu connection ea ls. used with on opezr that as the connection 58 is ll will he lifted from its seat 53, pt I tents of the tanl; to how l'eplllly down l hpm valves ordinarily have the valve cssiu vided with on opening in whlcl 1 extending downwardly near the tank so es to deliver the supp ,j' to after flushing without any uuuet or splashing.

While 2 have shown and described my haventlon as embodied in the form which est present consider host adapted to carry out its no see, will be understood that it is capable oi modlficsp tics, and that I do not desire to be limited in the interpretation of the following claims except may be necessitated by the state of the prior What I claim as new, andoeleslre to secrete by Letters Patent of the United States, is:
