HENRY C. 'WEEDEN, OF BOSTON, MASSACHUSETTS.
AUTOMATIC FLUSHING DEVICE.
SPECIFICATION formingpart of Letters Patent No. 415,260, dated November 19, 1889.
Application filed March 13, 1889. Serial No. 303,172. (No model.)
To all whom it may concern:
Be it known that I, HENRY C. VEEDEN, of
Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, 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 SlillllfllStlllCture whenever the same is used, in which de vices a siphon iiushing-pipe extending from the supply-tank to the bowl to be flushed is set in operation by means of rarefaction of the airin the long leg of the siphon, this rarefaction being produced through the instrumentality of an air-exhaust pipe extending downwardly from a point in the long leg to a point 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 when the bowl is used produces the exhaustion or rarefaction of air in the long limb of the siphon.
In the accompanying drawing I have represented in vertical section and elevation a device embodying my present improvement.
In the drawing, A represents the tank; B, the siphon flushing-pipe; O, the bowl to be flushed; D, the outlet thereof, and E the airexhaust pipe.
In the operation of my improved structure the rarefaction or exhaustion of airis obtained by causing thefiuid from the urinal to pass in the form of a jetthrough a body of air with which the exhaust-pipe connects, and past its mouth. I accordingly form at a convenient point below the bowl a contracted or jet orifice F, as shown; The exhaust-pipe, as shown, in order to produce the best results, should enter the dischargepipe D just below the point where the jet leaves the orifice B. As this orifice, to produce the best results, should be of small diameter relatively to the whole bore of the discharge-pipe, I provide a branch or supplement G of the discharge-pipe of a caliber sufficient to carry off the flushing water, and I prefer to trap this branch G as well as the pipe D. If not so trapped, it is obvious that a passage-way would be left for gases from the drain to the apartment.
As the operation of the device will be found to depend somewhat upon the relative caliber of the various pipes,l will state that good results will be obtained by giving to the supply-pipe B a diameter of three-fourths of an inch, and to the discharge-pipe D, Where it leaves the bowl, a diameter of one and onequarter inch, to the exhaustpipe a diameter of one-fourth of an inch, to the jet-orifice a diameter of one-eighth of an inch, and to the branch pipe II a diameterof one and onefourth inch.
The operation of the parts is as follows: The drawing representing the parts at rest, if fluid be introduced into the bowl of the urinal, it will pass down into and back up within the contracted portion of the discharge-pipe above the j et-orifice, and will escape therefrom forcibly in the form of a jet. This jet passes through the body of air which lies within the discharge-pipe below the jetorifice and around the mouth of the exhaustpipe, and produces a rarefaction or exhaustion of the air therein, and this in turn rarefies or exhausts the air in the long leg of the siphon, and thus starts its flow. WVhen the flushing water descends, it will pass off partially through the jetorifice, but mainly through the branch pipe G,and thence through the discharge-pipe to the sewer.
I claim In a device for causing the automatic flushing of the bowl of a urinal or similar structure, the combination, with said bowl, its supply-tank, and siphon flushing-pipe, of a discharge-pipe leading downwardly from the bowl and having a j et-forming orifice located therein, an air-exhaust pipe extending from the long leg of the siphon flushing-pipe down to and entering the discharge-pipe below the jet-forming orifice, and an auxiliary or branch discharge-pipe G, all substantially as set forth.
In testimony whereof I have hereunto subscribed my name this 9th day of March, A. D. 1889.
HENRY C. \VEEDEN.
