E. BOYLE, In, of same place, am administraitor, did invent. certain new and useful Improvements' in Flushing Apparatus for War ,ter- Olosets, of which the following is a ,sp'ecification, being in the words of the specification to of said JAMES E.

above the water-level in the tank. "Inside the '50 or 'chain-. ;togfa weighted levenp, which keeps 8 5 the suction is produced in great part by the action of the injector I, as will presently be described.

The operation of my invention will be best understood from the diagrams, Figs. 2 and 3. In these the pipee is not shown as passing through the pipe *r, but for clearness the two are placed side by side, and the bell n and upward extension F are exaggerated. normal water-level in the tank E is'shown by the line a: :r. The parts are shown in 'Fig. 1 in their normal condition, the chamber F being empty, and the valve h closed. When the person using the closet pulls downward on the wire or chain q, through the usual pull-handle or other suitable appliance, the valve h is lifted and water from the tank E commences to flow rapidly into the chamber F, and immediately thereafter to flow outward through the orifice 'i. Fig. 2 showsthe parts in this condition. As the inlet-orifice h. has about sixteen-times the area of the the valve h will drop back ,to itsv seat.

outlet-orifice 'i, the water enters the chamber F much more rapidly than it can escape from it, and quickly fills the chamber, expelling the air through the tube F and pipe f. By the time the chamber is thus filled the water running out through the orifice'iand descending the flushing-pipe will commence to flow into the bowl A, and the user hearing it will then naturally release the pull, whereupon The I water contained in the flushing-chamber will then continue to -fiow out through the orifice, i, until the chamber is emptied. Fig. 3-shows the apparatus shortly after the valve h is closed? From the time the water entering the chamber reaches the orifice 2' until the chamber is emptied there is a continuous stream of water flowing out through this orifice, falling through the cavity or injectorchamber in the casting G, and flowing down the flushing-pipe. In crossing the cavity in the casting it'encounters and carries with. it a portion of air, and so creates a partial vacuum in thiscavity in the manner common to injectors. This partial vacuum or suction extends up through the passage t into the bell n, from which it draws the air 'for an instant, and until the water in the chamber F rises above the bottom end of this bell and so seals it and prevents any further flow of airinto it. The rarefaction rapidly increases from that instant, and air is drawn up through the pipe e and from the space d. The etfect of this rarefaction is to siphon the trap 'O or cause the water to flow over this trap and fall into the trap D, and. this siphoning proceeds rapidly until the water-level inthe bowl A is lowered to the outlet-opening a, whereupon air enters the space d-from the bowl and breaks the vacu'um.- This breaking of the vacuum should occur shortly after the first of the flushing-water reaches the. bowl, and thereafter the water enters the bowl and is as rapidly drawn out by the siphoning of the trap, thereby. causing a pow-,

The

eri ul outflow through the bowl and soil-passage, which carries with it the entire contents of the bowl. In the course of this operation the vacuum may be broken several times by entrance ofair from the bowl. In any case the rarefaction in the. bell 'n will cause the water to rise to a greater height in it than in the chamber F, as shown in Fig. 3, and it the suction is sufficiently strong the water in the bell will be drawn up to the top of the pipe 4',

and will descend through the passage t, mixed with air. Thusthe water will be drawn from the chamber F to the pipe I through two conduits simultaneously. The rarefaction in the bell n, pipe (2, and spaced will continue 1mm the water in the chamber has so far run out as to unseal the bottom of thebell, whereupon the vacuum is broken finally by the entrance of air into the bell, and thereupon the remaining water will flow into the bowl as an after-wash) and will fill it up to the level shown, leaving it ready for the next use of the closet. The precise operation will depend upon the proportioning ofthe parts, as by altering the relative capacities of the trap ber F, and the relative areas of the orifices h and i the operationmight be considerably modified.

I have stated that the person using the closet will naturally release the pull when he hears thewater pouring into the bowl, and if the parts are so proportioned. thatwhe'nthis 0, space d, pipee, bell n, passage 15, and chamoccurs the chamber F will be filled, the operation willalmost invariably bev satisfactory.

If he should release the pull too quickly, the

only result would be a proportionately shorterflush, and if he should hold the pull too long,-

the flush would be unnecessarily prolonged,

the only disadvantage of which would be a waste of more or less water. To prevent the latter contingency a self-seating valve may 1 be used, as the valve h. The valve'shown in my Patent No. 249,577, dated November 17,

1881, will answer the purpose well.

Fig. 4 shows a modification in which a valve of this character is used, in connection with w a different lever arrangement. The wire q is to be connected to the water-closet seat, and i the weight on the lever tends to lift the valve.

The parts are shown in full lines in the normal position.- When the seat is depressed, the lever is tilted to the position shown in dotted lines, thereby forcing down the piston c in the cylinder w, which is fixed to the valve h. The piston has a on pped-leather packing,

'lifts the valve 1?. to the position shown in dotted lines. The cylinder w has a small inlet-conduit or leak-passage 'y, adjusted by a screw 2, and as water slowly enters through is sealed in a fixed cup m Fig. 5 shows how two valves may be used, the arrangement of the valvesand the lever being the same asv in my said Patent No.

255,485. The outlet orifice 11 is made larger v than in the construction before -described,

andthe valve j, fixed to the stem u, works up and down through this orifice and, when lowered, seats-itself on the bottom of the casting G, over the orifice 2", whence the flushingpipe leads. The valve 3' nearly fills the orifice 'i, the area of the intervening annular space being about the same as of the orifice t in Fig. 1.' The two valves are so arranged that when the lever is at mid-stroke both are seated; but when the lever is' at either extremity of its stroke one valve is seated and the other is lifted. The upward extension F and bell are no longer distinct, and a check-valve g is interposed between the 'interior of the bell and the air-pipefleading from its top.

The parts are shown in their normal position. When the seat is depressed, the valve chamber F isquickly filled through theori- .fice h, and water flows thence into the bell n, the air'therein escaping through the valve g. Water also flows through the annulan opening 6, and fills the passage t to the same level. The chamber F, bell n, and passage t remain full until the seat is released, whereupon the valve h closes and the valve j opens. The water from the passage 6 and chamber F then commences to run outinto the pipe l,the former flowing the more rapidly and instantly producing a suction, which should suffice to lift the water in the bell-n and cause it to flow down the passage't. The water from the chamber F flows out through the annular orifice 'i, and descends through the flushing-pipe, and acts to cause. a suction or rarefaction in the same manner as in Fig. 1. This construction causes a more powerful and rapid suction than the other-,but I prefer that first described because of its greater cheapness, as its action is practically sufficient. v

It will be seen that my present-invention introduces a new principle for operating double trapped or siphon water-closets-namely,

that of producing the requisite vacuum by causing the falling flushing water to act'as an injector and draw air along with it. I have combined with this means for securing the The diagram Fig. 6, is designed to illustrate the essential principle of my present invention even more clearly than the preceding figures. The air pipee does not enter the chamber F, but isconnected by a branch with the flushin g-pipel below the chamber, the injector I be ing arranged at their junction. The valve 9 is shown merely to prevent water settling back and flowing down the pipe e, since the top of this pipe is below the water-level x 00, instead of above it, as before. No provision for securing an after-Wash is here shown, but the bowl may be refilled after the flushin g by any suitable means, 'as by water admitted by a valve through an independent flushing-pipe.
