FLUSH|-NG APPARATUS FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 378,100, dated February 21, 1868.

' Application filed January 25, 1886. Serial No. 189,581; (No model.)

To aZZ whom it may concern: Be it known that I, SAMUEL G. MOFARLAND, of the city and State of New York, have invented an Improvement in Flushing Appara-.

tus for Water-Closets, of which the following isa specification.

The object of this invention is to create a suction between the two traps of the watercloset sufficient to produce a siphoning action that discharges the con-tents of the closet-basin.

To effect this object the entire flushing-cistern is inclosed, so that the descent of the water therein when it fiows to the closet-basin pro The flushing-cistern A is of any desired size,

or shape, and the water is to be supplied into the same by a ball-valve or other convenient mechanism. B is the pipe leading from the flushing-cistern to the rim G of the water-closet bowl D, and within the flushing-cistern A is a siphon-pipe, E, with a valve, F, at its lower end, and this pipe and valve are lifted by a 10d,G, and any suitable connection to the pull passes. 'rod G; but ordinarilyit is sufficient to make of the water-closet. The parts thus far named are of any ordinary character, exceptthat the flushing-cistern is closed on the top by a plate or plates, H, that is air-tight,or nearly so, and in the same is a hole through which the rod G There may be a packing around this the hole but slightly larger than the rod.

At the back of the watencloset bowl D is the vertical dam T, and a siphon-discharge, K, leading down to the lower trap, L, that intervenes between the siphon and the sewer-pipe M,and the partition P,between the siphon and the bowl D, is convex at the side next the bowl D, asshown in the drawing, the object of this convexity being to throw the water that issues from the flushing-rim O at the back of the closetsufficiently away from the dischargeopening between the basin and the siphon to fall upon andsubmerge any paper that may bepartially floating in the water of the basin,and thereby compel the discharge of the paper with the rest of the contents of the basin through the siphon and trap, as hereinafter stated.

From the upper part of the siphon K a pipe, S, passes up into the flushing-cistern, the upper end being near the under side of the cover H.-

- flushing-cistern rushes rapidly down the pipe B into the bowl of the closet through the flushingrim 0, and the wateroverflows thevertical dam T in the siphon K, and the descent of the water in the cistern A produces minus pressure of atmosphere in the upper part of said cistern and'draws the air out of the siphon K through the pipe S, so that this siphon fills with water, and the column of water in said siphon K, the trap L, and sewer-pipe M causes a powerful current that draws the water out of the bowl D and discharges the contents thereof, andauy paper which might otherwise float iuthe-bowl is submerged and carried away with the water, as aforesaid. The rapidity of discharge causes the level of the water in the bowl Dto'descend so rapidly that air is drawn into the siphon K and the same ceases to act, and air rushes up into the cistern to supply the minus pressure therein. The water runs from thecock Q to refill the cistern,and I providea smallpipe,R, opening at its lower end below the valve-seat into the pipe B, and the upper end is in the discharge-opening of the cock, so that a porobstructed.

I do not claim a water-closet cistern in which there is a-flushing-chamber closed at the top and provided with an air-valve and with a valve to admit water into the flushing'chamher, and a flushing-pipe and valve leading to the closet, and an air-pipe from the trap of the closet up into the-flushing-chamber; neither do I claim a closet-basin having inclined concavo-convex sides over which the water flows and in which the action of the water is nearly uniform all around the basin. By my improvement the water acts above the trap to submerge paper or other floating substances, and at all other portions of the basin to drive the contents of thebasin toward the discharge-openin g.

B, leading to the rim of the closet, a. valve at 15 the upper end of such pipe, a siphon-tube connected with thevalve, and a rod passing through the cover of the cistern and connected to the siphon and valve for lifting the same when the closet-pull is operated, substantially as set 20 forth.

Signed by me this 2lst day of January, A. D. 1886.

SAMUEL G. MCFARLAND.
