To all whom it may concern:

Be it knownthat I, FRANK SGHUH, a citizen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have invented a new and Improved Flushing Apparatus, of which the following is a full, clear, and exact description. y

The invention relates to sanitary apparatus such as water closets, sinks, urinals, traps andthe like.

The object of the invention is to provide a new and improved flushing apparatus arranged to insure proper emptying of a tank or like rece tacle, for flushln purposes through a sip oning action of t e contents of the receptacle and a subsequent refilling of the receptacle with water from a water supply. Another object is. to dispense withthe numerous metallic fixtures liable to corrode and now generally employed, such as supply and flush valve-s, metallic siphons,

overflows, feed and refill pipes, rubber ball valves, metal floats, leather valves and rub- Another object is to simplify the construction by using comparatively few parts not liable to get easily out of order, thus insuring long life to the flushing tank. 7

In order to produce'the desired result use is made of a tank or similar receptacle of porcelain, glass or other vitreous material, and a siphon within the tank and integral therewith. Use is also made of a combined float and dumping reservoir of a single piece of vitreous materlal and capable of delivering a proper amount of water to start the siphon. A A practical embodiment of the invention is represented in the accompanying drawings forming a, art of this specification, in

which similar 0 aracters ofreference indicate corresponding parts in all the views.

Figure 1 is a sectional front elevation of the flushing apparatus applied to a. water closet tank, the section being on the line portion of the flushing apparatus and show- Specification of Letters Patent.

. an inlet is the combined float and reservoir in' ing the siphon and the water inlet in secglass or other suitable vitreous material and is closed at the top by a suitablecover 11 of the same material. Within the tank is arranged a siphon 12 which forms an integral part of the back and bottom of the tank 10, and this siphon 12 is provided with 13 and an outlet leg 14, pref erably ma e rectangular in cross section and gradually diminishin in size fromrthe entrance end of the in ct leg to the terminal of the outlet leg, as will be readily understood by'reference to Fig. 5, to insure a proper siphoning action, as hereinafter more fully explained. The lower end of the inlet leg 13 is provided with an integral foot15 having large entrance openings 16 at the sides and front, and having small apertures 17 )in the topflas plainly shown in Fig. 5. It is understood that when the water is siphoned out of thetank and its level reaches the top of the foot lfi then air is sucked into the inlet leg 13 by way of the small apertures 17 to quickly break the siphon action. The lower end of the outlet leg 14 termi- .nates in a foot 20 the top of whlch "extends to the .front of the tank 10, and a portion of the top .forms the bottom of the foot 16,

by the upper end of the outlet pipe 24 connected 'wi th the bowl of the water closet for flushing the same. It is understood that I do not limit myself to this connection be-,

tween the outlet opening 22 and the bowl of the water closet, as the outlet 0 'ning 22 ma be connected in any suitabe manner wit the water closet bowl. 1

Within the upper portion of the tank 10 is arranged a combined .fioat and dumping reservoir 25 made of a single piece of vitreous material such as porcelain, glass and the like.

7 The front and back of the combination float and reservoir 25- are provided with lugs 26 through which extends Patented Apr. 8, 1 ers.

Application filed September .26, 1917. Serial No. 193,371. 7

is fitted a .thimble or bushing 23 engaged the a transverse rod 27 engaging at its

ends feet

28 and 29 attached to the front and back of the tank 10. By the arrangement described, the combination float and reservoir 25 1s free to swing, as hereinafter more fully explained. The combination float andi'eservoir 25 is arranged to form a float 30 and a reservoir 31, of which the float 30 serves to return the combination float and reservoir 25 to normal position on the refilling of the tank 10 after the same has been emptied of its contents by the siphon 12; The reservoir 31 is adapted to be filled with water to provide an additional amount of water to be emptied into the tank 10 to raise the level of the water therein to a level above the top of the siphon 12 to start the latter. The reservoir 31 is provided with a bottom, a

portion 32 of which is approximately at a right angle tothe front, back and- The reservoir 31 is filled with water' through a spout 40 extending from a valve casing 41 screwing on the upper end of a water supplypipe 42 extending vertically within a tubular passage 43 forming an integral part of the top and bottom of the tank 10 and of one end of the siphon 12, as plainly indicated in the drawings. The lower end of the water supply pipe 42 extends through an opening 44 in the bottom of the tank 10 and that of the passage 43, and the lower end of the water supply pipe 42 is connected in the usual manner with a suitable source of water supply. A washer 45 and a nut 46 engage the lower end of the water supply pipe 42, and the washer 45 abuts against the under side of the bottom of the tank 10 to make a tight joint of the water supply pipe 42 with the bottom of the tank. The valve casing 41 is provided with a rabbet 47 engaged by a washer 48 of rubber or other suitable material and seated on the top'of the passage 43 to form a tight joint between the passage and the valve casing 41. The bottom of the valve casing 41 is provided with openings .49 which connect the interiorof the valve casing 41 with the interior of the passage 43. The valve casing 41 is provided with a valve seat 50 controlled by a valve 51 mounted to slide up and down in a bearing 52 formed on the top of the valve casing 41. The outer end of the valve 51 is provided with an opening 53 through which extends a lever 54 fulcrumed at one end at 55 on afbracket 56 integral with the the bottom of the combination float and reservoir 25. A set screw 68 screws in the socket 64 against the shank 65 to secure the latter in place after the same has been adjusted up ordown to move the friction roller 67 in proper position relative to the inclined portion 33. When the combination float and reservoir 25 is in the normal position shown in Fig. 1 then the friction roller 67 is at the upper end of the inclined bottom portion 33 and consequently the lever 61 bears by its fork 60 on the free end of the lever 54 whereby the latter holds the valve 51 firmly to its seat50 thus shutting oif the water supply at this point. When the combination float and reservoir 25 is tilted, as shown in Fig. 3, .then the inclined bottom portion 33 moves out of engagement with the friction roller 67, and the pressure of the water in the water supply pipe 42 now opens the valve 51 'to allow the water to flow from the water supply pipe 42 through the valve seat 50 into the valve casing 41 and from the latter by way of the spout 46 to the reservoir 31. The Water flowing into this reservoir 31 overflows the latter when in tilted position and refills the tank 10, and in doing so the rising water engaging the float 30 causes the combined float and reservoir 25 to swing back into its normal position, as shown in Fig. 3. When this takes place the friction roller 67 is reengaged by the inclined bottom 33 and consequently a swinging motion is given to the lever 61; which by-the fork 6O bears down on the lever 54 whereby the valve 51 is movedinto closed positionfto shut off the water supply.

'In order to swing the combined float and V reservoir 25 from the normal position, shown in Fig. 1, into dumping posltio'n, shown in Fig. 3, the followin arrangement is made: The front of the tan 10 is' provided with a bearing 7 0 (see Fig. 2) in which is mounted to turn a shaft 71 p'rovided'at its outer end with a suitable handle 72 under the control of the user of the water closet to impart a turning motion to theshaft 71. The inner crum rod 27. On turning the shaft 71 in' f either direction the

corresponding friction roller

74 or 75 bears on the front wall of the combined float and reservoir 25 thus impart- 7 ing a swinging motion to the combined float bottom portion 32 so that the water contained in the reservoir 41 readily flows out of the same. a

It is expressly understood that the float 3O is'an integral part of the reservoir 31 and is in the form of a hollow body completely air and watertight.

-51 is held in close The operation is as follows: When the several parts are in the position shown in Figs. 1, 2-4 and 5 then the valve d position, the reservoir 31 is filled with water and the tank 10 is filled with water, the level of which is at the top of the siphon 12. Now when the operator swings the handle 72 to one side and givesa quarter turn to the shaft 71 then the

corresponding friction roller

74 or 75 of this arm imparts a swingingmotion to the combined float and reservoir 25 and swings the latter into the tilted position shown in Fig. 3. The combined float and reservoir 25 when swung into this tilted position discharges its contents over the inclined bottom 33 into the tank 10 thus raising the level of the water contained therein to a distance above the siphon-12 whereby the latter is started and the Water is rapidly sucked out of the tank 10 by way of the siphon and discharged into the water bowl by way of the outlet, as previously explained. The water is drawn out of the tank 10 very quickly and far faster than the flow of the water through the upright small spout 40, and when the water has fallen to the level of' the foot 15 of the inlet leg 13 of the siphon 12 then the siphoning action is broken and further outflow of the Water from the tank 10 ceases. By reference to the drawings it will be noticed that the wall of the outlet opening 22 is spaced from the walls of the foot 20 of the outlet leg 14 and hence when the siphon isin action and the water rushes down the outlet leg 14 into the horizontal foot 20 then it rushes into the outlet pipe 24 from all sides and consequently an exceedingly strong siphoning action is had as the water readily flows through this pipe It will also be no.

When the combined float and reservoir 25 swings into the-tilted position mentioned andshownin Fig. 3 then the friction roller 67 is released and with it the levers 61' and 54 to allow the pressure of, the water against the under side-of the valve- 51 to raise the latter thus permitting" the latter to flow from the supply. ipe 42 by way of theopen v I valve seat 60,-vave casing 41 and-spout'4O into the reservoir 31. The water flows out of this reservoir 3;1-into' the tank 10 and. re-

fills the same, and as the water rises inthe tank 10 it finally engages the-float 30 thus causing an upward movement of the same to return the combined float and reservoir 25 is filled, with the level of the water-therein 'to normal positionat the time thetank'10- normal position the valve 51- is moved back onto its seat 50 thus shutting 0a the water supply. A small aperture 80 connects the interior of the foot 20 ofthe outlet leg 14 of the siphon 12, with the'lower end of the passage 43't0 allowthe small amount of .water contained within the passage 43 to downward moving float 34 displaces water in the tank whereby the level of the water in the tank is raised quickly and a considerable distance to insure a ing of thesiphon.

It is understood that when the valve 51 is open, as previously explained, a portion of the water passing into thecasing 41 passes by way of the apertures 49 into the passage 43 to fill the same and this amount of water is utilized for refilling the how] after the same has been flushed.

It will be noticed that by the arrangement described the metal valve casing 41 and its valve 51 and the operating mechanism thereof is located above the level of the water in the tank 10 and consequently is not subjected to the corrosive action of the water. It will also be noticed that the siphon 12 is an integralpart of the tank 10 and is made of the same vitreous material of which thetank 10 is made and consequently is not liable to the corrosive action of the water; in fact, the many metallic fixtures now generally employed in flushing apparatus of this character, such as supply and flush valves, metallic si hons, overflows, feed and refill pipes, rubber ball valves, floats, leather valves, rubber valve seats and quick and forceful start- 1 5 Although the siphon 12 is shownin structure is integralwith the front or elther' side of the tank it defines substantially a chamber in which the combined float and 15 reservoir swings and is maintained.
