This invention relates to a substantialand practical improvement on the present method of flushing a closet bowl.

Two types of water closets are most in use;

[namely the so-called wash-down and the siphon A ll wate'r closets empty on the principle of; siphonic action. This is obtained by means 'oif a.

a flushing tank or a' flushing valve in combination 10 with a water closet; both apparatuses are providedwith a comparatively large outlet suitable tooEt-ain'a large volume of water,1to rush into the-bowl through the flushing rim at a very reduced pressure over that of the main ,water pp y. f

A water closet of a siphon jet' type, is provided with an opening at the bottom of the bowl, thus when it is flushed the water enters first through i said opening, forming a large, short and very slow 0 jetfwithout siphonic actionj but itstimul'ates the flushing action by only starting the water .up the gooseneck, which, simultaneously receiving the rushing water from theflushing rim, forms'the 'siphonic action which flushes the bowl," I

The flushing of the bowl with this type of siphon jet is somewhat quicker and more efficient than in awash-down type water closet which does not carry a'siphon jet. 1

1 Water closets, flushing tanks or flushing valves as customarily constructed and usedin combination with a water closet, haveseveral disadvantages. 7

The so-called siphon jet ha'sno siphon action, thus theflushing of the bowl'is slow, and as it does not perform the function that its name implies'it cannot be considered a siphonjet.

In all types ofwater closets the,f lushing water has not suificient pressure to always cleanse the bowl thoroughly. 7 a

"The wash-down type watercloset, while less expensive than the siphon jet type is not so eflicient' and sanitary.

"rne flushing tank action is slow andhas the tendency to stir up the contentsin the bowl, cause ing the odors to permeate into the room.

All flushing valves; as commonly in use have the I inconvenience that they cannot work ,unless connected with a pipeline of not less than one 6 inch diameter, thus resulting much more-expensive than the piping required for the flushing tank; generally speaking, homes are equipped with half inch or less pipeline, for the flushing apparatus, therefore, a flushing; valve cannot 5 be used, but only a flushing tank.

The object of my'invention' is to overcome'all of water supply, thus in all cases the complete apparatus showing the two siphonjet the above described inconveniences, and principally the inefiiciency oi the so-called siphon jet,

, Up to the present, either flushing tanks or flushing valves must have a. large outlet for the flushing water, in order to obtain promptly a large volume of water at a much reduced pressureand of course speed than that of the main water supply, whereas in my case a very much smaller outlet for the passing of the flushing water is required so as to obtain a much lesser volume of flushing water, but at the maximum ressure and speed obtainable, bycausing it to a pass from the originalsize of the water conduit to. a very much reduced passage of a nozzle, a The ordinary water closets, cannot resist the highpressure of the main water line, whereas my improved: one is provided with suitable conduit or conduits to resist said pressure. a

The cleansing of the inside walls of the .bowl is done by the water atfull pressure from the'main cleansing is absolutely thorough. j s The foregoingobjects and advantages together with i'ny subsequent features which may be developedin the description, maybe best apprecie ated from a description read in conjunction with the drawings in which:

Opening -34 centrally located on the removable flange 13, the

.. contour of which is smaller at the back than the back of the contour of seat 30 mounted thereon, is clearly shown in Fig. 5. The purpose is to protectthe undersurfa'ce of seat 30 from any splashings from the inside of the bowl- 35 is an jet 36frombidet nozzle 37 to strikethe inside walls of bowl '7, thus protectedby the undersurface of removable flange '13, the splashings of saidjet 36 will beprevented from spilling outside of bowl 7. r

.Escutcheon' 26. is held in position'by screw 38,

mounted to flushing valve cover 39., The piston valve member .40 is provided with ports 41 into which enters the water supply; outlet 61 thereof distributes the water into chamber 47, supplying the water to perforated conduit 48Iand to chamber 43 for thewater supply to siphon jet flushing nozzles 10 and '11, passing through elbow 44, nipple 45, T shaped fitting 46 and conduit 15.

Fig. 5 shows control valves 49 and 50; 49 to operateflushing valve 27, and 50 to operate bidet nozzle 37; c o n d uit 51, one endthereof is mounted the siphon jet flushing nozzle, which in this new to outlet 52 of flushing valve 27, the other end is mounted to control valve 49. Water conduit 53, one end thereof is mounted to outlet 54 of flushing valve 27, the other end to control valve 50, more clearly shown in Fig. 6 The T shaped conduit 46 carries a perforated member 48 in two' pieces for the cleansing of the inside walls of the bowl and the refilling thereof.

Fig. 6 shows flushing valve 27 with inlet 55 for the water supply; outlet 52 to operate flushing valve 27;'outlet' 54 to operate bidet nozzle 37;

outlet 56 to operate the siphon jet flushing nozzles 10 and 11; outlet 57 to operate the perforated conduit 48; conduit 51 carries the water supply from outlet 54 to control valve 50; nipple 58 supplies the water through the T shaped fitting 46 to perforatedfflm 48. In dotted line is shown a section on line YY Fig. 5 of a fragment of the removable flange 13 carrying hinge posts 28. and 28-a, provided with means to fasten them to said fiange 13, carrying bidet fixture 29 and toilet seat 30 swingably mounted thereon asshown in Fig. 4.

Fig. 7 shows flushing valve 27, threaded cover 39 carryingthreaded hole 77 to receive screw 38 to keep in positionescutcheon 26, as shown in 9 Fig. 4. Piston valve 40, centrally mounted, distributor member 60. at one end and closed by tap 60-a provided at the top end with port 41 for the inlet of water supply from chamber B and through conduit62to outlet port 61, alternately. distribut- .ing the water supply by the movement of said pistonvalve 40 into chambers .47 and 43 and viceversa during thelu'pward and downward stroke of said piston valve member 40.. i

As flushing valve 37 carries a pipe line of a much smaller diameter than that carried and required by an ordinary flushing valve, in order to supply the water at the maximum pressure to device terms the siphonactio'n to flush the bowl, it" cannot at the same time supply the water to perforated rim 48 without hampering the siphonic action of the flushing nozzle.

It is understood that as an ordinary flushing valve is provided with "a pipe line supplying a larger volumeof'water' than the one above de-. scribed, it cansimultaneously supply the water to I the perforated conduit and flushing nozzle, but

it requires two separate outlets carrying conduit 89 of a smaller diameter than conduit 90 shown in Fig. 10, thus preventing the water supply from dropping to inadequate pressure from that re-. quired for the flushing action of the flushing nozzle. V I

In 'theevent an ordinary flushing valve is wanted, but with only one outlet, this also-can be done,

namely by providing apipe line of such a diameter that when simultaneously supplying the water to perforated rim and to the nozzles, the pressure of the water supply will not drop so as to hamper the flushing action of the nozzles. But in'both these last described cases the pipe line must be much larger than the A9," required for this new device." V I In said Fig. '7, bushings 64 and 65 are suitably mounted, to form chamber 43, from which the water flows through conduit 15, shown in Fig. 4

to supply the water to siphon jetnozzles 10 and 11 also shown in Fig. 4, bushing 65 acts also as a seat for valve 72. Conduit 62 is provided at one end with. an extension 66 threaded at the end thereof,receiving-nut 67 to hold in position washers-68 and 69, leather cup 70, member 71 carrying rubber valve '72, by-pass 73 to keep in communication dash-pot chamber A with water supply chamber B; conduit -76 is for the outlet from dash-pot chamber A to operate flushing valve 27, herewithxmore specifically described. Thisnewflushing valve, generally speaking is based on the a mounted to the'case thereof for the reasons al-.

ready explained, but in substitution carries con-' duit 51 extending to one side of the closet bowl 7 connected to control valve 49, which in turnis mounted to bidet fixtureconduit 29. 'When'control valve 49 is operated it relieves the pressure in the dash-pot chamber A. Area of dash-pot being greater than area through main valve seat 65, the water supply to the valve, forces main valve'72 upwardly, openingvalve '72 and forcing water from dash-pot chamber A through'passage '76, conduit 51' and finally to control valve 49, discharging into'the conduit ofbidet fixture 29 and through bidet nozzle 37- into the bowl of water closet '7.

When control valve 49 closes, the water from Isupply enters dash-pot'chamber A through bypass 73 allowing main valve '72 to travel downwardly, causing valve to close. The'refilling of the bowl. is obtained when the outlet passage 61 of water supply is shut off by bushing 64 in the clownward stroke of piston valve 40, thus causing the water to enter chamber 47 and through per forated conduit 48 until main valve 72 is re'seated.

Fig. 8 shows the T shaped member 46 with perforations 1 closely placed, thus providing plenty water at the same pressure of the water'su'pply,

thus thoroughly cleansing in all cases the rear inside walls of the bowl; 48 shows a fragment of the perforated conduit shown in Figs. 4 and 5.

Fig.9 shows inlet for the main water supply,

7 outlet 56 to supply the Water to siphon jet flushing nozzles 10 and 11, outlet 52 to operate flush ing valve 27; outlet 54 to supply the water to bidet nozzle 37 and outlet 57 to supply the water "built-in conduit 95, the walls thereof of suitable dimensions to resist the high pressure of the main water supply, for the watersupply to nozzle 11; threaded cap 96 carrying chamber 97 and,

perforations 98 to permit the water supply from conduit 95 to enter conic conduit 99. of nozzle 11, discharging at the other end taking the shape of a conic jet 100 of great speed, discharging into goose-neck 101, thus forming the siphon action, substituting the water coming from the flushing rim which flushes any ordinary water closet. Flushing valve 87 connected to the main water supply conduit 88 and the two outlet conduits 89 and 90 connected to the bowl with spouts 102 and 103 which supply the water to the two separate chambers 92 and 93, rubber diaphragm separates the valve'into an upper chamber C anda lower chamber D with the pressure the same on both sides of diaphragm 80 equalized by by-pass 81; the slightest touch of handle grip 82 pushes in plunger 83 which tilts auxiliary valve 84, releasing the pressure in upper chamber C, then the pressure below in chamber D raises the entire working parts; 84 auxiliary valve, 80 diaphragm and 86 guide, which, is mounted to seat of auxiliary valve 84, allowing th'ewater 104; while this is occurring, a small amount travels up through by-pass 81 andgradually fills upper chamber C, thus-closing the valve formed bydiaphragm 80 on annular seat105 carried by the flushing valve 27. chamber 0; 107 is the outside cover which holds the other members in position. l 08-is 'a port for the passage of the water supply to conduit 90. Spring 109 is to' pushback in position plunger 83,

which isheld in position by guide 110.

In view of the factthat the siphon jet applied to the ordinary water closet does not flush the bowl, but improves the flushing slightly, as explained, where as in my new apparatus either both or only one of the siphon jet flushing nozzles are able to form the siphon action in combination with the gooseneck to flush the bowl, without the help of any water from any other additional source; therefore, it is clear that the water coming from conduit 48, as shown in Figs. 4 and -5 performs only the function of cleansing the inside walls of the bowl and the refilling thereof.

The principle on which thefiushing of an ordinary bowl is based, is that of a relatively large'volumeof water dropping into the bowl, thus by gravity causing the siphon action in combination with the ,gooseneclr whereas in this improved device the flushing of the bowl'is based on the principle of the speed by which the water is discharged through anozzle suitably shaped,

whereby a jet of water, conically shaped invades entirely, at great speed the channel of the gooseneck, thus forming the siphon action that flushes the bowl. i a

From the foregoing description it will be seen that the purpose of my invention has been ac- 'complished by the device as shown, and that the siphon jet flushing nozzle entirely precludes the inconvenience of a siphon jet without siphonic action, as the one at present in use, atthe same time rendering a j water closet of the utmost sanitation'yalso this new type of flushing valve eliminates the inconvenience of the necessity of which flushes the bowl to go down through barrel 106 is the inside cover of a pipe line of a diameter of not less than 1, as

it can work satisfactory with A9," and even pipe line. This desirable result has been obtained without complications or increased cost.
