One object of this invention is to provide a toilet tank Ifrom thence either of a rather small quantity or arather large quantity of water may be flushed as the case may be,
`whereby flushing water may be economized.
tank and to supply fresh water to a wash basin automatically, whereby one who usesthe toilet may retidy loneself after washing ones hands so as to keep not only ones hands but also ones clothing sanitary.
Further another object of this invention is to provide a toilet tank provided with a flush valve which may be operated without leakage.
Briey stated in accordance with one aspect of this invention, there is provided atoilet tank in a toilet room. The toilet tank comprises a fresh water supply pipe, a drain pipe, and a manually actuating member. supply pipe has a cock which is controlled automatically by a controlling element in accordance with height of the surface of the water reservoired in the tank. A feed pipe is extended from the cock to a faucet. Fresh water jetted from thefaucet is reservoired in the tank. The drain pipe is extended to a valve seat arranged inside the tank and adapted to be closed by a valve body to be placed on the seat. The valve body is adapted to be raised from the seat up to either of a position or another position higher than the former` by operating the manually actuating member `arranged outside the tank, whereby the water jetted from the faucet and reservoired in the tank may be flushed into the drain pipe by either of a rather small quantity or a larger quantity alternatively.
111e invention will be better understood and other objects and additional advantages of the invention .will become apparent upon perusal of the following description taken in connection with the drawings, and the scope of the invention wi-ll be defined in the `appended claim.
in the drawings,
FIG. 1 is a vertical sectional view of a toilet tank ernbodying the principles of this invention.
FIG. 2 is a horizontal section of the toilet tank shown in FlG. l taken on the line 2-2 thereof.
FIG. 3 is a vertical sectional view of any enlarged scale of a ush valve body provided in the tank.
FlG. 4 is a partly axially sectional side view of a yfaucet provided with the tank.
FiGQS and FIG. 6 are a plan and an elevation of'a toilet room provided with the toilet tank in accordance with this invention and a Japanese type closet.
PEG. 7 is a similar view to FIG. 5 but provided with a European type closet.
Similar numerals refer to similar parts throughout the several views.
Referring more particularly to the drawings, there is a toilet tank 11 in a toilet room. A wash basin 12 is placed on the upper edge of the toilet tank 11. A drain pipe 13 is provided through the bottom wall of the tank 11. The top end 14 of the drain pipe 13 protruded inside the tank 11 has a valve seat 16 adapted to place a flush valve tion :14 of the drain pipe 13 just below the valve seat 16, extending laterally and ending with an upward opening which is connected with a vertical overow pipe 18.
Two horizontal brackets 19` spaced vertically with each other are secured on they overflow pipe 18. `A valve rod 15 iscarried by the brackets 19 vertically slidably ythrough eyes provided at the free ends thereof. A shaft 21 is extended being journalled by a bearing seat 24 iixed on the front wall of the tank 11. Av handle Zit is secured on the front end of the shaft 21 and a Acomma-shaped fcrankv22 is secured on the rear end of the shaft 21. The
freeend of the crank 22; is connected with the valve rod 15A by means of a link- 23,the rod 15 being protruded vertically from the valve body 15. Twostopping elements 25 are protruded rearwards from the bearing Seat24.
A protectivesleeve 32 is providedy vertically along the walll of the tank 11il inside thereof. A supply pipe 30 is extended vertically along the wallr of the tank 11, riseskvertically in the sleeve 32, and is bent inwardly at the top. A cock Z8-:is provided atthe inner endof the supply pipe 30 andV the cock 28- is controlled byl a mechanism 291 which isv connected with a floatv rod 27 ending in a float 2 6. adaptedwto iloat on the water. The supply pipe 3i) is secured to the sleeve 32 leaving a cylindrical space 31 therebetween by means of a packing 33 at the top of the sleeve 32 and a packing 34 and a nut 35 at thelower Vend of the sleeve 32. A feed pipe 36 is extended upwards from the cock 28 through the margin 12 of the wash basin 12 and terminates with a foaming faucet facing the Wash basin 12'.
The foaming faucet comprises a faucet body 49, an
v inner cylinder 41, and an outer cylinder 47, as shown in FIG. 4. Y The faucet body 49' is screwed on a collar 5i) fixed to the end of the feed pipe 36 and the inner cylinder 41 is, in turn, screwed on the faucet body 49. A disc 45 having a plurality of perforations 44, two or three netted rings 42 overlaid axially with one another, and a sleeve 43rfinsertedbetween the disc 45 and-the innermost netted ring are arranged within the inner cylinder 41 and kept in place by means of the somewhat narrowed `outlet of the inner cylinder 41. The sleeve 43 and the inner cylinder 41 have common radial windows 4hL so as to inhale air into the passageway of water extending through the perforations 44 and the netted rings 422.. The outer cylinder 47 isscrewed on the base offthe inner cylinder 41 and left a cylindrical air passageway 48 opening at the front end of the faucet so as to pass air to the windows 46 without fear of sucking in soiled water and other obstructions directly. The water thus supplied from the faucet to the wash basin 12 then hows into the toilet tank 11.
The handle Ztl may be turned in either direction, and either of the turns is adapted to be restrained by the stopping element 25. Because of the comma-shape of the crank 22, the lifts of the valve rod 15' differ from each other when lthe handle 20 is turned in the clockwise direction and the counter-clockwise direciton. 'That is, the valve rod 15 may be raised higher when the handle 20 is turned in the clockwise direction than when the same is turned in the counter-clockwise direction.
Thus when the handle 20 is turned in the counterclockwise direction, a rather narrow passageway for passing the waste water reservoired vin the tank 11 is opened between the valve body 15 and the valve seat 16, while when the handle 20 is turned in the clockwise direction, a broader passageway is opened at the same place. When the valve body 15 is raised not higher, the waste water flowing through the passageway between the body 15 and the seat 16 acts to replace the valve body 15 on the seat 15 so-that when the handle 20 is released the body 15 is resetted on the seat 16 closing the drain pipe 13. Meantime, when the valve body 15 is raised higher by means of turning the handle 20 in the clockwise direction, the valve body 15 is kept in its raised position during the waste water runs out of the tank 11 until the surface of the waste water in the tank 11 descends down to the valve body 15. Then the surface of the water carries the valve body 15 down to a lower position so as to act the rapid closure of the latter. The flush Valve body 15 comprises a conical upper half and an invertedly frustro-conical, rounded lower halfvadapted to match with the valve seat 16 and defines an internal cavity which opens at the bottom thereof, as shown in FiG. 3. By virtue of the shape of the lower half of the valve body 15, the bodyl can cooperate with the seat 16 without fear of leakage.
When the surface of the waste water reservoired in the tank 11 is lowered, the float 26 is also lowered. When the float 26 is lowered down to a predetermined height, the float 26 acts on the controlling mechanism 29 so as to feed fresh water towards the faucet resulting in to supply a quantity of fresh water in the wash basin 12 for washing hands. The water supplied -to the basin 12' ows into the toilet tank 11 at the same time.
In the faucet, the fresh water is accelerated by virtue of its passageway passing through the perforations 44 of the disc 45 resulting in admitting air to form a quiet foaming jet stream at the netted rings 42, the air being supplied from the cylindrical air passageway 48 through the window 46.
. FIG. and FIG. 6 show an arrangement of a Japanese type closet A which may be also useful as a urinal, and a toilet tank 11 according to this invention, connected therewith. When the closet A is placed on a properly higher oor B, it may be possible Ito be used as a European type toilet. Meantime, FIG. 7 shows a toilet room equipped with a European type toilet. In either case, the drain pipe 13 is connected with the inlet C of the closet A by means of a connecting pipe D, from whence a soil pipe having a double siphoning trap E is extended externally. It' is preferable to embed the toilet tank 11 partly in a side wall of the toilet room when a rather hat toilet tank is to be installed.
While a particular embodiment of this invention has been illustrated and described, modifications thereof will readily occur to those skilled in the art. It should be understood therefore that the invention is not limited to the particular arrangement disclosed but that the appended claim is intended to cover all modifications which do not depart from the true spirit and scope of the invention.
What is claimed as new and desired to be secured by Letters Patent of the United States is:
