FLUSH'ING APPARATUS.

Appli-cation filed October 12, 1926. Serial No. 141,218.

This invention has reference to an improved flushing apparatus for water closets, bidets, shower baths and similar apparatus, the object of the invention being to provide an apparatus in which the discharge of water from the tank is controllable at will, trom the smallest amount to a continuous discharge.

The invention consists essentially of a completely closed tank, into which water is delivered through a tube provided at its end with a valve, the tank being also'provided with an outlet pipe equipped with a valve. These two valves are mounted on a single carrier for movement in unison and are operated by the same lever. rIhe inlet valve is normally in a slightly opened position and the outlet valve closed. Operating the lever the outlet valve can be opened at the same time that the inlet valve is opened wider; during this operation water is discharged t-hrough the outlet pipe under pressure due to the accumulation orn air in the top portion orn the tank, the pressure of which corresponds to the pressure in the water supply pipe` .By keeping these valves opened at'ter the forced discharge of water has beengproduced, a continuous stream of water is obtained as long as required.

In order that this invention may be thoroughly understood Aand easily carried intoY effect, it has been illustrated in one of its preferred forms ot construction in the accompanying drawings, in which:

Figure 1 is a vert-ical section ot the apparatus.

Figure 2 is a plan view of the adjusting` sleeve.

Figure 3 is a side view ot the apparatus, and

Figure 4 is a plan view of the same.

In all the figures, the same numerals indi cate similar or corresponding parts.

The apparatus includes a tank 1, of more or less rectangular section and having a cone shaped bottom. On the top wall ot the tank is screwed a cover 2 which is provided with an internal passage to which the water supply pipe 3'is connected and which has a cap scr-ew rIhe tank has two llugs 5 which serve to hang it in the desired position.

An adjusting sleeve 6 is screwed in theA bottom of the tank and is locked in position by a nut 7, and to the end of said sleeve the connection 8 of the outlet pipe is screwed.

The internal passage in the cover 2 also communicates with a vertical tube 9 attached to said cover and which has at its lower end a sleeve- 10 vcontaining within it a. valve 11, between which valve and the bottoms of the sleeve a rubber washer 12 is interposed that constitutes a seat for said valve when the latter is fully closed. i i

This sleeve is followed by another sleeve 13 provided with lateral perforations for the passage of water into the tank. The said valve 11 is mounted on a rod 14- which eX- tends through tube 9 and projects downwards carrying two washers 15, 16 held to it by pins 25. Between washer 15 and sleeve 13 a thick rubber washer 17 is placed which acts as a spring and'between the two washers 15, 16 there is a rubber piece 18 which forms the outlet valve and rests on the seat formed by the top portion of the adjusting sleeve 6.

The upper end ot the rod 14 projects through the cover 2 and through the packing 21 contained in a stung box formed by the

interi'itting parts

19 and 20; the part 19 being screwed into the cover and having screwed on it an outer sleeve 22, the upper edge of which has the form ot a screw or cam. A complemental part 23, whose lower edge also has the form ot' a screw or cam, rests on sleeve 22, as shown, this part 23 constituting the hub of the operating handle. The top end of the rod 14 projectsthrough this hub and carries a retaining button 24 fastened to it by a pin 25.

The adjusting sleeve 6 has for its object screwing it in or out will cause said valves, due to their being fastened to the same rod 14, to open more or less. Said adjusting sleeve should be turned the extent necessary for the inlet valve 11 to be suciently separated from its seat tor allow the tank to be filled in a convenient length ot time. The opening of this valve 11 will, therefore, depend on the size of the water feed pipe and to adjust the closing of the valves, since on the pressure of the incoming water. A Y

plug 26 is screwed into the top wall of the tank to release the pressure within the tank when necessary. y

To operate the apparatus, it is merely necessary to turn the handle 23 which, by means orp its cam hub, will cause an upward movement of rod 14 and, with it, the outlet valve 18, thus compressing thespring or cushion 17. The compressed air in the top portion ot the tank thereupon Jforces the escapes into the tank through the perfora" pipe. At the saine time, the inlet valve 11 is raised further away fromits seat, so that the v Y volume'of water normally contained in the tank and then being discharged is increased by the water that iiows through pipes 3 and 9 and, passing through the sleeves 10 and 13,

tions in the latter sleeve. Consequently, the initial .violent or forced discharge of water is always succeeded by the discharge of a continuous stream of water so long as valve 18 `remains open.

As soon as the handle is released, cushion 17 expands, thereby lowering rod 14 and closing valve 1S, while the inlet valve 11 returns to its normal position, leaving suiiicient opening for the incoming water to refill the tank until the air pressure in the tank balances the pressure of the water and the inflow ceases. It is to be understood that valve 18, being made of rubber, will yield slightly underV the pressure of the water in the tank and will produce, as a. result, a slight downward movement of rod 14 and valve 11, so that the latter may, at a certain water level,

seatagainst washer 12 depending, of course, upon the normal position of said valve with relation to the washer. This normal position is regulated by the adjustment of sleeve 6 whei'eon valve 18 rests; and because of-that fact, such adjustment will `vary the time required for iilling the ta-nk, as will be understood.

Y lt is evident that the invention can embody forms, proportions and details' of construction other than those herein illustrated and -water tank provided at its bottom with an outlet; a water inlet tube mountedy in the tank inline with 'said outlet and'provided at its lower end with a laterally-perforated sleeve to enable the passage of water through said tube into theV tank; avalve rod passing through said sleevek and tube and project-ing `at its upper portion through the top of the tank; an inlet valve and an outlet valve fixed one above the other to said rod for movement in unison therewith, the inlet valve being disposed within said sleeve for coaction with'a valve seat therein abovethe pei'forations to controlthe outflow of water through Vsaid perfoi'ations, and the outlet valve acting to open and close the tankoutlet; and an operatin'gmember attached to the projecting por# tion of the valve rod to raise or lower the same. ,j

2. Flushing apparatus, comprising a closed water tank provided at its bottom with an` outlet; a water inlet' tube mounted in the tank inline with said outlet and provided at its lower end with a laterally-perforated sleeve to enable the passage of water through said tube into the tank; a valve rod passing through said sleeve and tube and projecting at its upper portion through the top of the tank; an inlet valve and an outlet valve iiXed one above the other to said rod for movement in unison therewith, the inlet valve being disposed within said sleeve for coaction with a valve seat therein above the perfor-ations to control the outflow of water through said perforations, and the outlet valve acting to open and close the tank outlet; an operating member attached to the projecting portion of the valve rod to raise or lower the same; and a spring cushionmounted on said rod Lbetween Vthe bottom of the sleeve and the outlet valve and acting normally to force the rod downward. Y Y

8. Flushing apparatus, comprising a closed kwater tank;aii adjusting sleeve mounted for projecting at oposite ends into `the adjusting i sleeve andthrough the top of the tank; a water'outlet pipe in threaded connection with said adjusting sleeve to permit the vertical movement of the latter with relation to the former and to the tank bottom; an inlet valve and an outlet valve fixed one above the other to the valve rod for movement in unison therewith, the inlet valve being disposed within the perforated sleeve forV coaction with a valve seattherein above the perforations to control the outflow of water therethrough, andV the outlet valve being adapted to seat upon the upper face of the adjusting sleeve; a spring interposed between the bottom of the-apertured sleeve and the outlet valve to force said outlet valve and the valveV rod downward so as to hold4 the outlet valve against itsseat, whereby the vertical movement of the adjusting sleeve will raise or lower the valve rod and its valves; and eX- ternal means for raising or lowering said rod independently ofthe movement effected by the adjusting sleeve'.
