CISTERN.

SPECIFICATION forming part of Letters Patent No. 718,483, dated January 13, I903. Application filed March 15, 1902. Serial No. 98,369. (No model.)

T0 at whom it may concern.-

Be it known that I, DAVID LEMLEY, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Improvement in Cisterns, of which the fol-' lowing is a specification.

This invention relates generally to cisterns, and more particularly to one provided with attachments for aerating the water and also with an attachment for the prevention of the propagation of malarial germs and mosquitos.

Another object of the invention is to provide overflowing-discharge attachments, so that the cistern can be quickly and easily cleaned whenever desired and all sediment removed therefrom.

With these various objects in view the invention consists in the novel features of construction and combination, all of which will be fully described hereinafter, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a view of the cistern provided with my improvements. Fig. 2 is a sectional view illustrating the attachment whereby the propagation of germs is prevented. Fig. 3 is a detail perspective view of the oil-holder. Fig.4 is a sectional view illustrating the upper end of the aeratingpipe and the connection between said pipe and the overflow-pipe.

Referring to the drawings, A indicates a cistern, which may be of any desirable construction, and B is a supply-pipe leading to said cistern. This cistern ispreferably provided with a wire-gauze cover 0 in part or whole, although such construction of cover is not absolutely necessary.

A four-way coupling D-is connected to the cistern adjacent to its lower end, and to one member of said coupling is connected the aerating-pipe E, which extends upwardly to a point level with the top of the cistern. The upper end of said pipe is preferably protected by means of a piece of wire-gauze E. By

means of this pipe a definite quantity of air is permitted to enter the cistern from the hottom and passing up through the water will aerate and purify the water contained within the system.

A draw-oil? cock F is connected to the lower member of the coupling D, and by meansof this cook the contents of the cistern can be quickly and easily removed and all sediment cleared away from the bottom of the cistern. In order to prevent the propagation of germs and mosquitos, I employ a pipe G, which passes horizontally through the coupling D, the inner end being turned upwardly within the cistern, as shown at G. The outer end of the said pipe is turned downwardly and has a spherical oil-holder H connected thereto, and between the said oil-holder H and coupling D is arranged a valve or cock I. The spherical oil-holder H is formed with a tubular internally-threaded neck H, which is adapted to screw upon the threaded end of the pipe G, and the packing-ring H of rubber, is interposed between the upper end of said neck and the annular collar which surrounds the lower end of the pipe, as most clearly shown at G a K indicates the overfiow-pipe,provided with a receiving-head K, arranged level with the upper end of the cylinder, and the connecting-pipe K unites the overflow-pipe K with the areating-pipe adjacent with their-upper ends.

The oil-holder H is filled with oil and connected to the lower end of the pipe G, and by opening the valve or cock I a quantity of oil is forced therethrough and passes upwardly through the water and forms an oil skim upon the top of the water, thereby preventing the propagation of germs and mosquitos, so common in cisterns now in use. When the supply of oil becomes exhausted, the holder H will be filled with Water, and it can be quickly and easily removed, the water discharged,refilled with oil,and connected again to the pipe G. It is obvious that if the draw-off cock F be opened, the pipe E open, the cock I closed, and the water emptied from H and H replaced, the globe being filled with oil, that the lower part of E and the pipe between I and H will be filled with air. Then if the valve in the pipe E above the coupling D (and this valve can be at any height con- 10o venient to reach) be closed and the valve F closed the air contained in said pipe will be gradually forced into the cistern and escape upward through the water contained therein. Also the air confined between the valveI and globe H will be forced into the cistern when oil is admitted.

By the attachments herein shown and described I am enabled to keep water in the cistern pure and clean, as it is obvious that inasmuch as there is no commingling with the oil and water the oil contained within the cistern will not be affected by the small quantity of oil required to maintain the thin skim or covering at the top, and, furthermore, it will be readily understood that the contents of the cistern can be quickly and easily discharged at any time it is desired to clean the cistern.

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

1. A cistern having a four-part coupling connected thereto adjacent to its lower end, an aerating-pipe connected to said coupling, a discharge-cock connected also to the coupling and a pipe passing through the coupling, the inner end being turned upwardly within the cistern, and an oil holder or receptacle attached to the outer end of said pipe, substantially as specified.

2. The combination with the cistern, of a four-part coupling adjacent to its lower end, an aerating-pipe connected to said coupling, a discharge-cock connected also to the coupling, a pipe passing through said coupling and having a valve or cock connected therewith, a spherical oil holder or receptacle attached to the outer end of said pipe, and an overflowpipe connected with the cistern at its upper end, and also connected to the aerating-pipe adjacent to its upper end, substantially as described.

3. In a device of the kind described, the combination with a pipe turned upwardly at its inner end, and downwardly at its outer end, a cock or valve arranged intermediate the ends, and a spherical oil holder or receptacle secured to the outer end of said pipe, and a packing-ring interposed between the neck of said receptacle, and the collar surrounding the pipe, substantially as described.

DAVID LEMLEY.
