FLUSHING APPARATUS FOR WATERr-CLOSETS.

To all whom it may concern Be it known that I, FRANCIS M. MAoKIN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Flushing Apparatus for WVater- Closets, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has relation to flushing apparatus for water-closets of that class wherein, upon the lowering of the water-closet seat, a valve, preferably located underground below the frost line, is opened and permits water to flow through a supply pipe to a closed tank and, when the seat is allowed to rise, the supply valve will close automatically and a second valve will be opened to permit the water from the tank to flow into and flush the closet bowl.

The object of my invention is to produce a flushing apparatus of the above character which will be of comparatively cheap and simple construction, containing as few parts as possible, not liable to disarrangement while in use and easily adjusted and repaired in case of necessity.

My invention consists in the novel construction and combination of parts hereinafter described and claimed.

I have illustrated my invention in the ac companying drawing wherein:

Figure l is a side elevation of a complete apparatus including a water-closet and a flushing tank having my improvements applied. Fig. 2 is a vertical sectional view of the flushing apparatus and a portion of the water-closet and seat shown in Fig. 1. Fig. 3 is a rear elevation of the parts shown in Fig. 1.

My invention is applied to water-closet bowls of any of the usual constructions and I have shown it as applied to an ordinary hopper closet, 1, which is formed with rearwardly projecting lugs 2, pierced for the reception of bolts 3, that pass through the lugs 2, and are secured in position by nuts 4, the bolts 3, being formed with eyes 5, on their upper ends to receive the pintle 6, of the seat hinge 7. The hinge 7 is rigidly secured to the seat 8 and is formed with upwardly angled and rearwardly projecting arms 9, terminating in rounded ends 10. Between the arms 9, is arranged a crosshead 11 which is formed with curved lugs 12, extending outwardly over the upper Specification of Letters Patent.

rounded ends 10 of the arms 9, the crosshead being thus supported on the arms, but without other connections between them so that the cross-head may be moved upwardly and allowed to descend vertically when the arms are swung on the pintle 6 by the lowering and raising of the seat.

The closet bowl 1, is formed with a spud 13, in which is secured the coupling member 14, that is connected by a nut 15, to the horizontal branch 16, of a valve casing 17. The valve casing 17, has a horizontal branch 18, diametrically opposite the branch 16 and the branch 18 is connected by an elbow coupling l9, and a vertical pipe 20 with a closed flush tank 21.

Vithin the branch 16 is arranged a hori Zontally pivoted flap valve 22, that seats against the beveled edge of a passage 23, formed in a vertical partition 24, that intervenes betweenthe main casing 17, and the branch 16. The flap valve 22, is provided with a lug 25, that is downwardly beveled on its lower side, from its base to approximately its outer end, as shown at 26, and this lug is engaged by a laterally extending tooth 27, carried by a collar 28, formed on the vertically movable valve stem 29. The valve casing 17 is provided with a screw cap or top 30 having a stufling box of the usual form and the stem 29, extends through this stufling box and is threaded at its upper end and screws through the cross-head 11. A vertical spring 31, is arranged between the collar 28, on the valve stem 29, and the cap or top 30 and this spring serves, when the seat 8 is relieved from pressure, to raise the seat and at the same time to force the valve stem 29 downwardly.

The main valve casing 17, is connected by a section of pipe 32, with a supplementary valve casing 33, that is preferably arranged in the ground below the frost line, when the closet is located out of doors, being usually located at about the level of the soil pipe trap and said supplementary valve casing is provided with a waste branch 34, that.

communicates with the soil pipe by a pipe 35.

Within the supplementary casing 33, is located the vertically movable valve 36, which is carried on the lower end of valve stem 29, and, when at its lowermost position, seats at 37 and closes the inlet passage 38, which is connected to the water supply pipe, (not shown). The upper portion 39 of the valve 36 is cylindrical in form and fits snugly in the central cylindrical portion of the valve casing 33, and when the valve is in the elevated position shown, tightly closes the waste passage in branch 34.

The supplementary valve casing 33, is formed with a curved passage 40, which extends as shown from a point just above the valve seat 37, to a point above the position occupied by the upper portion 39, of the valve 36, so that when the valve is in the elevated position shown in the drawing, there will be free passage for water coming in through inlet passage 38, around the valve 36.

Operation: The parts being in the position shown in the drawing, with the closet seat held down, the water from the source of supply flows through inlet passage 38, and thence through passage 40, pipe 32, main valve casing 17, elbow coupling 19, and pipe 20, to the tank 21, which becomes filled with water which is retained therein, so long as the closet seat is held down. Upon releasing the closet seat the spring 31, raises the seat and forces down the valve stem 29, and causes the valve 36 to seat at 3'7, and close the inlet 38, and at the same time opens the waste passage to the soil pipe through branch 34. The descent of the valve stem releases the lug 2 from engagement with the tooth 27, whereupon the flap valve 22, swings back from its seat and the water flows through the branch 19, into the closet bowl until the tank 21 is emptied. After the tank has been emptied, the water which remains in the lower part of the main valve casing and the pipe 32, drains off slowly through the waste passage in branch 34, to the soil pipe. As soon the bowl has been flushed and the flow of water from the tank ceases, the valve 522, swings down against its seat 23, and thereafter, when the closet seat is depressed, and the valve stem 29 is drawn up by the upward pressure of the arms 9, on the cross-head 11, the tooth 27, engages the lug 25, and pulls the valve tightly against its seat and holds it there until it is again released by the raising of the lid. The upward movement of the valve stem 29, raises the valve 36, from its seat, thereby allowing the water to again flow into the tank and at the same time closing the waste passage through branch 34, to the soil pipe.

I claim:

1. In water-closet flushing apparatus, the combination of a main valve casing, a flap valve adapted to close the outlet of said main valve casing, a supplementary valve casing, a valve in said supplementary valve casing adapted to control the inlet passage thereof, a valve stem carrying the last named valve, means carried by said valve stem for holding the flap valve in closed position when the valve in the supplementary valve casing is in open position.
