UNITED STATES PATENT OFFICE.

CISTERN.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed September 11,1905. Serial No. 277 996.

To all whom it may concern:

Be it known that I, JOHN S. ATTENHOFER, a citizen of the United States of America, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Cisterns, of which the following is a specification.

This invention relates to cisterns and tanks, and is designed more particularly for receiving and storing rain-water.

An object of the invention is to provide novel means to permit the water within the cistern to support a layer of oil, provision being made for permitting the discharge of the water of the cistern without disturbing the oil. By this means insects cannot gain ac-` cess to the water of the tank or cistern, and such a cistern would be eliminated as a breeding-place for insects.

A further object of this invention is to provide novel means for causing displacement of the sediment at the bottom of the tank where the water ilows to the discharge-pipe, and as a further means for causing displacement of the sediment the water is supplied to the tank through an elbow, by which a circular movement is given the water.

Another object of the invention is to produce a novel device of this kind wherein the water at the bottom of the tank is the first to be discharged.

A still further object of this invention is to provide a cistern wherein the discharge-pipe is protected by a removable cap in order that access to the jacket containing the discharge pipe may be had, and the cap forms a complete siphon when the water reaches the top of the cap.

With the foregoing and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts, to be hereinafter more fully set forth and claimed.

ln describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts in both views, in which- Figure 1 is a sectional view of the cistern with the discharge-pipe in elevation. Fig. 2 is a sectional view of the discharge-pipe and its jacket.

ln the drawings, A denotes a tank, or it may be the wall or lining of a cistern above or dug in the ground, where suflicient elevation is afforded to cause proper running of the water.

B indicates a discharge-pipe which preferably passes through the bottom of the tank and terminates a suitable distance from the top of the tank, it being the purpose of the inventor to have the end of the dischargepipe in such relation to the top of the tank as to cause the water to find its way out of the discharge-pipe when the water in the tank reaches a predetermined level. The exact proportions and relation may be varied to suit particular requirements.

A jacket C surrounds that portion of the discharge-pipe within the tank and preferably extends several inches beyond the end of the discharge-pipe. The jacket is -provided with a removable cap D, which may be removed to gain access to the interior of the jacket. This cap D is of such size as to have its lower edge beneath the level of the top of the discharge-pipe B. This capdoes not rest on the upper end of the jacket, but is held a slight distance therefrom in order that it may form a Siphon. To hold the cap in its position, any suitable means may be employed; but it is found advantageous to form with the lower edge of the cap arms b, which bear against thejacket C, and these arms may be of any number.

When the water rising in the jacket C reaches the to of B, a slight overflow is formed and wil continue as an overiiow until the water has reached the top of the jacket;

.but as the water within the cistern continues to rise and reaches nearly the top of the jacket C a full stream of water will pour down the pipe B and produce a siphon, and the siphon will continue until the water reaches a fraction below the cap D, when the siphon will break. By creating this siphon any accumulation of sediment that may occur at the base of the jacket will be drawn up and carried out through the pipe B, which will never occur if the pipe B always remains IOO as an overflow. The jacket C can be removed any time, as it rests loosely on the base of the cistern. Lugs e are arranged around the pipe B to center the jacket with relation to the said pipe B.

At a suitable distance from the bottom of the tank the jacket is flared, as indicated at E, and the iiared portion forms a chamber which is in communication with the tank and with the A, space surrounding the dischargepipe. The chamber is provided with a series of curved partitions F, forming dellectors, which also help to give the water at the bottom of the cistern the same circular motion imparted to the surface of the water in the cistern, causing the sediment to work itself to the center of the cistern and to be caught in the flared pipe or chamber to be discharged. The supply-pipe G preferably enters the tank at or near the top, and it has an elbow H, which causes the water to circulate around the tank, which movement aids in diverting the sediment to the chamber.

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

l. In a cistern, a suitable receptacle, a dischar e-pipe terminating near the top thereof, a jac ret for the discharge-pipe, means within the jacket for imparting a circular movement to the water entering therein andfa'fsuitable supply-pipe.

2, In a cistern, a suitable receptacle, a discharge-pipe, extending vertically in the receptacle, a jacket for the discharge-pipe, a flared bottom on the jacket in communication with the receptacle and partitions in the flared bottom for causing circulation of the water, and a suitable supplyipe.

3. In a cistern, a receptac e, a dischargepipe terminating near the top thereof, a jacket for the discharge-pipe, and curved partitions within the jacket causing circulation of the water, and a suitable supply-pipe.

In testimony whereof I alfiX my signature, in the presence of two witnesses, this 5th day of September, 1905.

JOHN S. ATTENHOFER.
