WIT 455555. \/%O%-v UNITED STATES PATENT OFFICE.
HENRY C. \VEEDEN, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE IVEEDEN SANITARY MANUFACTURING COMPANY, OF RHODE ISLAND.
AUTOMATIC FLUSHING DEVICE.
SPECIFICATION forming part of Letters Patent No. 416,136, dated November 26, 1889.
Application filed March 16, 1889 Serial No. 303,534:- (No model.)
T0 at 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 Devices for Automatically Flushing the Bowls of Urinals and Similar Structures, of which the following is a specificat-ion.
. My present invention relates to improvements in that class of devices which comprise a flushing-tank, a siphon flushing-pipe extending therefrom, and a bowl adapted to be flushed by said pipe; and it relates to improvements in the apparatus by which the automatic action of this flushing-siphon is eitected when fluid is introduced into the bowl in use and as the result of such introduction.
In the accompanying drawing I have rep resented in vertical section and elevation a device embodying my present invention,
which I will now proceed to describe.
In the drawing, A represents the flushingtank, B the siphon flushing-pipe extending therefrom, and C the bowl to be flushed.
D represents the outlet of the bowl, and E a chamber into which this outlet leads. This chamber is so formed as to retain water in its lower part, as shown. A pipe F extends from the upper part of this chamber up to and communicates with the long leg of the siphon of the flushing'pipe B, and the remainder of this portion of the flushing-pipe should be provided with a trap G, or other suitable atmospheric cut-olf between the point of entrance of the pipe F and the point where the flushing-pipe B communicates with the bowl to be flushed. The discharge from the chamber E is by means of a siphon H, which leads to the drain or other receptacle for the flushing-water after it has performed its oflice. The height of the mouth of this siphon above the bottom of the chamber will govern the depth of the standing water therein, and the discharge-pipe D of the urinal should be carried down below the normal level of the standing water, as shown.
The operation of the device is as followsthe drawing representing the parts when at rest. Fluid introduced into the bowl when in use and passing down through the dischargepipe D into the chamber E raises the level of its contents up above the bend of the siphon H, thereby starting the same and withdrawin g the liquid therefrom. The withdrawal of the liquid from the chamber E by the action of the siphon H produces a partial vacuum or rarefaction ofthe air in the chamber and Withdraws in consequence through the pipe F a portion of the air in the long leg of the siphon flushing-pipe, and this produces siphonic action of that pipe and thus starts the flush. Such compression of the air in the chamber E as will be caused while the level of the water therein is being raised should be provided for. It may be done by an outwardly-opening relief-valve I, placed at some point where the air is under compression as, for example, at the top of the siphon, where such a valve is shown. It the trap I be of sufficient depth not to be broken thereby, a portion of the contents may be forced out and descend into the urinal-bowl without employing any special relief-valve.
I claim The combination of a flushing-tank, a bowl to be flushed, a siphon flushing-pipe extending from the tank to the bowl, a water-retaining chamber below the bowl, a passage from the bowl to the chamber extending below the water-level thereof, an air-pipe extending from the upper part of said chamber to the long log of .the siphon flushing-pipe, a trap or back air cut-oft therein below the entrance of said air-pipe,and air-pressure-relief valve, and a siphon-discharge from the said chamber, all substantially as set forth.
In testimony whereof I have hereunto subscribed my name this 14th day of March, A. D. 1889.
HENRY C. IVEEDEN.
