AUTOMATIC FLUSHlNG-SIPHON.

SPECIFICATIUN forming part of Letters Patent No. 334,606, dated January 19, 1886.

Application filed November 21, 1585. Serial No. 183,516. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM BARcLAY PAR- SONS, Jr., oftlie city, county, and State of New York, have invented a new and Improved Automatic Flushing-Siphon, of which the following isa full, clear, and exact description.

My present invention relates to the construction of an automatic and intermittent flushingsiphon adapted for use in connection with a water-closet or other form of trough, but designed more particularly to meet the requirements of such a trough as that forming the subject-matter of my application N 0. 174,804, filed August 19, 1885.

The invention consists of a main and auxiliary siphon of novel construction, as will be hereinafter explained, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of referenceindicate corresponding parts in both the figures.

Figure 1 is a longitudinal vertical sectional view of the water-closet trough above referred to, my improved siphoning apparatus being represented as applied thereto, and said siphoning attachrnent being shown in central vertical section; and Fig. 2 is an enlarged detail view of the siphon, the view being taken in' central vertical section. v

Referring now to the general construction illustrated in the drawings, A represents a trough below the seat-board B. This trough is the same as the trough heretofore described in my application above referred to, and consists of a box-like structure, of which the bot tom consists of a series of basins, each of which is provided with a weir or dam upon the side nearest the outlet of the trough, which outlet is shown at O, and leads to'the sewer or cesspool. With such a trough as has been described it is desirable that there should be some means whereby the trough can he automatically and intermittingly flushed, and it is to meet this requirement that I have designed the siphon forming the subject-matter of this application,which siphon will now be specifically described.

D is atank, fed by a pipe, a, the flow of water from said pipe being controlled by a stopcock, b, which can be set to deliver the amount of water required. Alarge pipe, E, passes up through the bottom of the tank D, and from this pipe E there is a' branch pipe,F, of rela tively much smaller bore, the top of pipe F being slightly lower than the top of E, so that water will flow down F before reaching the top of E. Thejunction a, where F branches out from E, is so arranged that a small pipe, G, of bore similar to F,can be tapped therein, so as to prolong F within the bore of E, as clearly shown in Fig. 3, in case it may be desired to increase the fall through E, the pipe E being jointed just below the junction, so that the mechanical part of this operation can easily be performed. The top of F'is covered by a small concentric cap, H,secured in any suitable manner, but preferably by means of arms e 6, while a large cap, I, covers the whole arrangement within the tank. This capI is held in adjustable position by a rod, K, that is secured to a boss, f, on the top of the cap, and passes through eyes formed in two horizontal arms, 9 g, which project from a vertical standard, h, that is rigidly secured to the side of the tank D. The

'arm g carries a set-screw, '5, arranged to bear against the rod K and bind it within the eye, which arrangement permits the cap I to be raised or lowered, so thatalargeorsmall depth of water can be drawn off from the tank D. The water from the pipe a is usually allowed to trickle in a small stream, so that the waterlevel in the tank D is slowly raised inside of the cap I and cap H. Now,cap H i n connection with pipe F, forms asiphon. When, thereforerw ater reaches the top of F, the siphon is automatically set in operation, and F being larger in size than the stream flowing from pipe (1, the water-level is quickly drawn down to bottom of cap H. On reaching the bottom H the rush of water draws air, which air' is that contained between the water-level and the top of the cap I, because air cannot rise up the pipe E against downflowing water from F to G. A partial yacuunris thus suddenly produced in cap l which is quickly followed by a correspbnding rise of water, and this rise of water will be sufficient to start the flow from the pipe E, which, being of large diameter, will quickly draw off the water in D to a level below the bottom of I, and the water so drawn will be rapidly discharged into the upper pan of the trough A,which the lower end of the pipe E enters, as best shown in Fig. 1. It will thus be seen that the purpose of the auxiliary siphon formed by cap H and pipe F is to cause the main siphon formed by I and E to operate with a very small supply-stream, which, if it flowed directly down E,would not be sufiicient to move the air in the pipe, and so cause the siphon to begin to flow.

In order to insure aperiodical discharge from E by breaking the vacuum in I, and thus allowing the tank D to be refilled,the lower edge, 1), of the cap' I is cut at an angle, sothat air will flow in at the uppermost point, 8, as soon as the water is drawn below such point; or the same result couldbe obtained by forminga V- shaped notch in one side of the cap. Cap H can be cut in the same manner, or straight, as desired. \Vhen the siphon formed by E and I begins to flow, as previously described, the water is discharged with great vehemence out of the pipe E and into the trough A, thereby flushing said tank.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Aflushing apparatus consisting of a main and an auxiliary siphon, the long legs of the two siphons being connected, substantially as described.

2. Aflushing apparatus consisting of a main and an auxiliary siphon. the auxiliary siphon being arranged beneath the cap of the main siphon,and having its long leg connected to the long leg of the main siphon, substantially as described.

3. A flushing apparatus consisting of a siphon formed by a pipe, E, and a cap, I, adustably mounted by means of a rod, K, said siphon being provided with an auxiliary siphon formed by a pipe, F, and a cap, H, substantially as described.
