,ELUSHING FOR .Ap plication filed May 27,
The invention relates to water closets of that type in which the water for flushing the bowl is forced by the air pressure being obtained by utilizing the pressure in the water mains; and has for its object, first, to provide a valve novel and efficient to control filling and flushing, which operates without spring and has no packing or parts working under significant friction, with the resultant advantage of saving in equipment and wear; and, second, to obtain, without wastage, just sufficient Water to reestablish the water seal in the bowl, after the bowl has been flushed.
One form of the invention is illustrated in the accompanying drawing, in which Figure 1 is a vertical section through a portion of the bowl and the reservoir showing the compartment and the valve applied thereto; Figure 2 is a section longitudinally and vertically through the operating valve, with dotted lines to indicate the water channel; Figure 3, is a section of the valve cap and the valve stem; Figure 4, is a section on line 44 of Figure 2 after the removal of the valve cap and closure valve. 7
A water closet bowl 1 and a pneumatic flushing reservoir 2 are preferably formed integral. This reservoir connects, at a suitable point (not shown), with a supply pipe leading from the water main. Adjacent to the said reservoir is a Water compartment 3 provided with discharging port 4: and an overflow port 5 on the front side thereof and which has a cover 6 thereover. In this compartment the control valve 7 is placed. The outlet end 8 of this valve is in open connection with the usual flushing passages. Through an elbow 9 communication is had of the inlet end 10 of the valve 7 with the pipe 11 by means of the joint 12 secured to the compartment floor. The valve 7 and pipe 11 are of considerably larger diameter than the water supply pipe.
The control valve 7 shown in longitudinal and vertical in Fig. 2, has an open bottom cylindrical chamber 13 formed at the annularly open top side of the valve casing 14 threaded at 15 for the reception of a closure cap 16 formed with and around the outer edge oar-Eur oF icE 0F BINGHAM, TIT-AH wATER-oLosE'rs 1829. Serial No. 366,336.
depending annularand internally threaded flange 17.
The closure valve is made of a valve stem 18-havinga frusto-conical member. 19 formed medially therearound and withithe lower end 55 i20-ienlarged and semi-conical in shape, with the bottom end thereof hollowed at 21. A preferably hollow rubber valve 22'fits tightly around thesteam 18 and against. the flange .19 with theienlarged end 20to hold it in .place'ithereon. The stem 18 is adapted to keep the :valve in alignment oven the valve J seat-123 by freely fitting up: into a guide "2 1 V vprovided by'a centrally and from the bottom sidebored: boss '16 which is concentrically fOIlDGd'OD the top side-0f the cap 16. The flange 19-isiof slightly smaller diameter than the chamber 13, so that when theclosure valve, forced upwardly by the incoming water, starts entering said chamber, as shown in 2, traps" the water therein, which slowly thenescapes therefromto avoid violent contact at the top of the valve. 7
The inlet end 10 of the valve '7 is 'forined 'SOTthatthe incoming water will completely surround' the valve seat'23- from all sides and to accoinplish this-an annular groove 25, with the dotted line 26 showing its lower-side, is formed therearound, so that when the closure 'valve is raised o'fi its-seat,the upward pres: sureoftheinco1ning water is equal at all sides of "the said valve, with the result that the friction of the stem 18 and -guide 24 is little .as possible.
Within and on the under side of the-casing 145m the-outlet end of said casing aboss'27 islformed which is centrally bored at 28 to receive the-control valve stern-29. The bore 28 is of largerdiameter than the stem* 29, 'so'th'at'the stenimay work freelythereinand water will also pass "downwardly around the stem, 'when it is' flowing out"through the outlet end'ofthe valve.
The-stem 29pivoted on the longer arm of a lever 81 actuates by manipulation of a plunger 32 pivoted on the opposite end of the lever 31 and mounted outside the compartment 3 in a position for convenient access by the user.
llhe operation will be readily understood. With the valve normally closed, when the main supply is introduced water will flow into the reservoir 2 until the air therein is compressed to a point to balance the pressure in the water mains; the closet will then be ready for flushing. Manipulation then of the plunger 32 actuates the stem 29 which engages in the hollowed end 21 and unseats the sure of the incoming water, while the trapped water in the chamber 13 escapes slowly therefrom. With the valve then fully open the flushing water will flow with force through the valve into the flushing passages untll the air in the reservoir 2 has reached atmospheric pressure atwhich time the said water slowly and withoutforce passes the valve; then the forces of gravity drop the valve 22 into its seat; the downward pressure of the water on flange 19 will then hold the valve closed and the water flowing from the supply pipe i into the reservoir 2starts filling it again.
While the flushing Water passes the valve some of it will pass downwardly through the ports and around the stem 29 to fill the compartment 3; should the compartment become 'overfull, the overflow 6 will allow the excess water to flow down into the bowl and k aid flushing; the water in the compartment 7 3 will flow out through the port 4; to again establish the water seal in the bowl after the bowl has been flushed.
It may be remarked that, the detailsof construction herein shown and described may be varied, if only the essentials of the invention, as pointed out in the appended claims, are maintained.
. I claim:
,1. A water closet comprising a pneumatic compression reservoir for storing water to flush the bowl, a pipe connecting the reservoir with the rim of the bowl for conducting the flushing water thereinto, a valve in said pipe between the reservoir and the rim of the means for filling said compartment comprises openings in the casing enclosing said valve through which a small amount of water escapes into the compartment when thevalve is opened, the main stream for flushing the bowl passing through the pipe into the flush ing rim. valve 22 to be raised fully open by the pres- PAUL eEoReioU.
bowl, a water compartment in which said valve is located provided with overflow and drainage openings and having a capacity sufficient to supply the water sealfor the bowl, means adaptedto be manipulated by the user for opening said valve and meansassociated with the valve for filling said compartment when the valve is opened for flushing the bowl.
2. A water closet as in claim 1, wherein the valve is mounted for free floating movement
