NITED STATES FLUSHING- CISTERN.
SPECIFICATION forming part of Letters Patent No. 605,972, dated June 21, 1898.
Application filed ugust 17,1896.
ed certain new and useful Improvements in Flushing-Cisterns, of which the following is a specification.
This invention relates to improvements in siphon flushing-cisterns for water-closets, urinals, or the like.
To carry out my invention, I employ two siphons, with the longer or delivery leg of the first siphon discharging into a bend or sealed vessel in connection with the bottom of the shorter or suction leg of the second siphon.
The height from the bottom of the shorter or suction leg of the first-siphon to the maximum level of the water in the cistern is a little less than the aggregate length of the two shorter or suction legs of the siphons. Consequently when the cistern is full the longer leg of the first siphon is more or less filled with air, and to discharge the contents of the cistern I allow the air to escape from this airspace. To allow the air to escape from the said air-space when required, I connect an air-pipe (which is carried above the level of the water in the cistern) to it, which air-pipe extends into a suitable vessel of mercury or its equivalent in a convenient position below. Then to release air I lower the, level of the mercury below the lower orifice of the airpipe, thus leaving the air in said air-space free to escape, and the contents of the cistern are at once discharged.
Reference is to be had to the accompanying sheet of drawings, forming a part of this speci fication, in which similar letters of reference indicate corresponding parts in each of the Figure 1 represents a sectional view of a cistern fitted with my improvements. Fig. 2 represents a plan view of the same. Fig.3 represents a diametrical section of the double siphon on the line a b, Fig. 1. Fig. 4 represents a sectional elevation, on a larger scale, of a device Imay employ to allow the air to escape when it is required to discharge the cistern. Fig. 5 represents a planview of the same. Fig. 6 represents a vertical section on the line y a, Fig. 4E.
The cistern A may be of any convenient Serial No. 603,040. (No model.)
construction, and the flush-pipe B is fitted with two siphons or a double siphon consisting of a coil-pipe O. The portion of the coil 0 from the opening or inlet end 6 to the central point 2' of the coil forms the first siphon,
while the, remainder of the coil from 'i to h forms the second siphon, and the air imprisoned in the bend of the first siphon, in conjunction with the water on each side of it, forms an air-trap and prevents the water rising high enough in the first siphon to flow over the top of the bend into the second one notwithstanding that the top of the water in the cistern is above the level of both, as shown by the broken lines, Fig. 1.
The air-pipe D, connected to the top of the bend of the first siphon, passes over the top of the cistern, and its lower end D is hermetically sealed by dipping into the mercury E, contained in the cup F. Consequently to discharge the cistern it is simply necessary to lower the mercury below the end D of the pipe to allow the air imprisoned in the siphon to escape. A convenient arrangement for this purpose and one not liable to get out of order is to float the cup F in a vessel G containing mercury H. The vessel G is provided with a lid J, through which the pipe D passes, and also with an opening for the push-stem K, secured to the vessel G. A push or button K is formed on the top of K. An air-' passage L is made in the side of the vessel G. The cup F and vessel G may be made of aluminium, and F has a piece F projecting down into the mercury by which to float it.
To prevent any possibility of particles of mercury being blown or carried out of the cup F by theescaping air, I provide the annular'shield or bafile F surrounding the end D of the air-pipe. This shield has openings F at the bottom to allow the mercury from the cup free ingress and egress. An annular shield D surrounding the shield F is also formed around the bottom of the pipe D It is evident that in case particles of mercury should be blown out of the cup F they will be directed by the shield F into the annular space between the shield D and the bottom D of the air-pipe and will consequently fall back'into either the inside or outside of F A pipe (shown by thebroken lines N) of the usual type and commonly termed an airpipe is connected to the crown of the siphon O.
"When the main or service pipe pressure is not suificient for a full-sized siphon of this class to work satisfactorily, one of a smaller caliber may be employed to start an ordinary single siphon, in which case the double siphon would be connected to the long leg of the ordinary siphon and its suction end preferably located at a little higher level than the suction end of the ordinary single siphon.
It is obvious that other means may be adopted to break the mercury seal to admit air to the air-tube.
Two siphons may be constructed with the second one below the other, or they may be arranged in any other suitable Way, so as to form an air-trap between them.
I claim- In a flushing-cistern, the combination with 'a tank, and two siphons having an air trap between them, of a pipe communicating at one end with the air-trap, a Vessel into which the other end of the pipe leads, said vessel containing mercury surrounding and sealing the said end of the pipe, a second vessel containin g mercury into which latter the first vessel dips and in which it floats, means for depressing the first vessel to break the seal around the end of the pipe, an annular shield or baffle-plate carried by the first Vessel and surrounding the sealed end of the pipe and having openings, and an annular shield on the said end of the pipe surrounding the shield on the vessel.
In testimony whereof I have hereunto set my hand in the presence of the two subscribing witnesses.
