AUTOMATIC FLUSHING DEVICE FOR URINALS.

SPECIFICATION forming part of Letters Patent No. 416,133, dated November 26, 1889.

Application filed March 11,1889. Serial No. 302,777 (No model.)

To all whom it may concern.-

Be it known that I, HENRY O. IVEEDEN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, 5 have invented certain new and useful Improvements in Automatic Flushing Devices for Urinals, of which the following is a specification.

My present improvement relates to that class of devices for producing an automatic flush of the bowl of a urinal or similar structure whenever the same is used, in which devices a siphon flushing-pipe extending from the supply-tank to the bowl to be flushed, is set in motion by means of rarefaction of the air in the long leg of the siphon, this rarefaction being produced through the instrumentality of an air -pipe extending downwardly from a point near the top of the long leg to a point in the discharge-pipe below the urinal-bowl.

The object of my invention is to improve the construction of the specific devices whereby the passage out from the urinal-bowl of liquid introduced therein produces the exhaustion or rarefaction of air in the long limb of the siphon.

In the accompanying drawing I have repre-' sented in vertical section and elevation a-de- Vice embodying my present improvel'nent.

In that drawing, A represents the tank; 13,

the siphon-discharge pipe; O,

the bowl to be flushed; D, the outlet thereof, and E the drawpipe or exhaust-pipe.

chanically confined therein.

The escape or rushing out of this water produces a rarefaction of the air in thelong leg of the siphon,

and thus'starts its flow.

For this purpose I form at a point upon the discharge-pipe of the bowl a chamber or enlargement F, into which the fluid introduced into the bowl will pass.

Into this chamber moreover. I lead a pipe E, and I close its extremity therein by means of a weighted valve G.

The weight of this valve is to be but slightly inexcess of the column of water normally standing in the pipe which it is to balance.

The dischargepipe D continues, as shown, beyond the enlargement F, and will preferably be trapped therein, as shown. The elevation of the mouth 5 5 of this lower portion of the discharge-pipe above the bottom of the chamber will govern the normal level of the waterleft therein after the flushing action.

In order that the introduction of fluid from the bowl into the chamber F shall cause the valve G to lift, I may provide it with a float, as shown in dotted lines, and when thus constructed the operation of the device is as follows: The parts are represented as in their normal condition, the exhaustpipe B being held full of water left by the previous flush, and counterbalanced therein by the weight of the valve G, and water also standing in the enlargement or chamber F, as shown. Now, if fluid be introduced into the bowl it will pass into the chamber F, raising the waterlevel therein and floating up the valve G. This releases the water standing in the drawpipe E, and the sudden downward passage of this water rarelies the air in the long leg of the siphon with which the pipe E connects and at once starts the siphon. I may, how ever, dispense with the float upon the valve by the following modification of the parts: I carry the pipe from the bowl into the chamber below the normal water-level therein, and I place in the upper portion of said chamber an outwardly-openin g air-relief valve f. Now, it the outlet -pipe D has the siphon form shown, the introduction of fluid from the bowl into the chamber, raising the water level therein, will start the siphon D, air-compression in the chamber being prevented by the opening of the relief-valve. \Vhen the siphon D starts, the withdrawal thereby of fluid from the chamber F, rarefying the air therein, will cause the valve G to lift and permit the water in the pipe E to flow down.

I make no claim herein to any method of operation of the device shown, the same forming the subject of an application filed by me March 15, 1880, and serially numbered 303,407.

I claim- 1. In a device for causing the automatic flushing of the bowl of a urinal or similar structure, the combination, with the said bowl, its supply-tank, and siphon flushing-pipe, of a discharge-pipe leading downwardly from the bowl, a water-chamber connected therewith, and a pipe extending from the long leg of the siphon flushing-pipe down to the said water-chamber and having its lower aperture covered by a valve weighted to counterbalance the column of water normally standing in the said pipe, all substantially as set forth.

2. In a device for causing the automatic flushing of the bowl of a urinal or similar structure, the combination, with the said bowl, its supply-tank, and siphon flushing-pipe, of a discharge-pipe leading downwardly from the bowl, a water-chamber connected therewith, a pipe extending from the long leg of the siphon flushing-pipe down to the said water-chamber and having its lower aperture covered by a valve weighted to counterbalance the column of Water normally standing in the said pipe, and a float attached to said valve, all substantially as set forth.

In a device of the character described,

' the combination of the following elements: a

outlet-pipe from the bowl to the said cham-.

ber sealed by the water therein, a pipe extending from the long leg of the siphon flushingpipe down to the said waterchamber and having its lower aperture covered by a valve weighted to counterbalance the column of water normally standing in the said pipe, and a siphon discharge-outlet from said waterchamber, all substantially as set forth.

In testimony whereof I have hereunto subscribed my name this 7th day of March, A. D. 1889.

HENRY C. VVEEDEN.
