WATER DlSTRIBUTlNG, COLLECTING, AND FILTERING APPARATUS.

SPECIFICATION forming part of Letters Application filed February 19, 1887 T0 aZZ whom it may concern.-

Be it known that I, JAMES S. ll/IARSH, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented eer tain new and useful Improvements in \Vater Distributing, Collecting, and Filtering Apparatus, of which the followingis a specification, reference being had to the accompanying drawing.

The object of my invention is to provide means for running off impure water and collecting pure water from roofs of buildings and filtering it for drinking and other purposes. To this end Iprovide means, in connection with ordinary roof-spouting, for running off into a sewer or elsewhere waste water, which first falls when a rain-storm begins, sufficient to wash off all the impurities which may be gathered upon the roof. Then I provide means for turning the current of water intoa tank, reservoir, or cistern, where it may be filtered, and after filtering may be drawn off for use.

In connection with the apparatus described I provide means for testing and determining, before admitting water into a cistern, whether it is running free fromimpurities, such as are liable to be deposited upon roofs.

In the accompanying drawing is showna vertical central section of an apparatus em bodying my invention.

The drawing serves merely to illustrate the invention, the form of which may be varied to suit different situations.

Referring to the letters upon the drawing to aid in describing my apparatus, as illustrated in detail, A indicates a tank or cistern divided into two compartments, Band C, which are separated by a filtering-partition, D, of any suitablekind. In practice I find that clay or bricks form a very good filtering-partition. This partition is preferably arched and rests on the bottom of the cistern and bears against one side of it as illustrated. \Vhen built in this way it will sustain itself in place,without any braces or stays or special appliances for the purpose, against the pressure of the water in the compartment B. Such a masonry filter, constructed of porous material, is very effective'and durable, in fact will last as long as the cistern itself. The partition D might extend up under the arch Y, as indicated in dotted Serial No. 228,l87.

Patent No. 367,051, dated July 26, 1887.

(No model.)

E indicates a pipe provided with a cock for drawing water out of the col'npartmcnt Gaffer it has been filtered. I

F indicates an iulet;pipe, which may be connected with the down spout from a roof in any usual way. This pipe is provided with a cock, or it might be a valve or cut-off, G, with a waste-pipe connection, H, and with a small faucet, stopper, or cock, I, as shown.

K indicates an ovcrflow pipe to be connected with a sewer or other device for conveying the water off the same, as by the wastepipe H.

The cistern,tank, or water-receptacle may be made of brick, stone, or other ordinary masonry and plastered on the inside with water-proof cement, or it may be made of wood or metal. In order to make aconvenient and secure covering, and at the same time provide an available opening in the top of the cistern, I make an annular casting, WV, flaring outwardly at thetop, as shown, and provided with a lower annular flange, X. This casting is adapted to serve the function of a keystone of an arch. It will rest upon the upper part of the arch Yof the cistern, and the flange X will project under the arch a short distance, so as to support or bind it, and at the same time prevent the casting from being raised out of place. Instead of a continuous flange, lugs or projections, either a part of the casting or attached to it, might serve the same purpose.

A lid, cap, or cover, Z, is applied over the casting to close the opening securely against the entry of surface water or any other deleterious substance into the cistern through the opening in the casting. Often the casting and cover will be underground, and it is important to prevent dirty water from soaking into the cistern; so I provide an annular flange, Z, on the cover, which projects over the edge of the casting \V, as shown. By means of the parts just described I insure a tight covering for the cistern, and at the same time a key for the arching walls near its top.

The operation of my apparatus is as follows: Ordinarily in dry weather the cooks will all be closed. When rain begins to fall, the cock G being closed, the water will escape with any washings from the roof to the ground or sewer out of pipe G. .Vhenitis supposed the water may be running pure from the roof, the small cock I may be opened to examine it and to let off the small quantity of impure water that may be above the cock G, so that it may not get into the cistern. When the water is thus tested and found to be pure, or as soon as it becomes pure-that is to say, free from roof deposits-the cock I can be closed and the cock G opened, which will cause the water to be delivered into the compartment B of the cistern or tank. Thence it will pass through the filtering-partition D and be deposited pure into the compartment (3, from which it may be drawn for drinking or other purposes.

It is preferable to make the compartment 0 small as compared with the compartment B.

By means of my invention it will be practicable at little cost for people dwelling in cities to have pure rainwater to drink at all times, notwithstanding the impurities that collect in considerable quantities on roofs and generally prevent the saving of rain-water in cisterns. This filtered water can be collected in cisterns in sufficient quantities for washing purposes, as well as drinking purposes, and this in many cities which are at present provided with very impure water is of material consequence. It is a fact that water in the city of Philadelphia, for example, has to be filtered even for washing purposes in order to do a nice piece of work of that kind during certain seasons of the year.

I am aware that it has been proposed here- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a rainwater distributing and collecting apparatus, the combination, with the tank or cistern A, of the inlet-pipe F, having the cock 0 and the small faucet or cook Land the waste-pipe H, substantially as set forth.

2. In a rainwater distributing and collecting apparatus, the combination, with the tank or cistern A, of the inlet-pipe F and its cocks G and I, the waste-pipe H, overflow-pipe K,

filtering-partition D, and outlet-pipe Eand its cock, substantially as set forth.

In testimony whereof I have hereunto subscribed my name.
