FILTER.

SPECIFICATION forming part of Letters Patent No. 224,680, dated February 17, 1880.

Application filed July 2. 1879.

To all whom it may concern:

Richmond, in the county of Madison and State of Kentucky, have invented a new and useful Improvement in Filters, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing, which represents a vertical central section of my apparatus.

My invention consists in afilterin which are combined a receiving-vessel and a filteringvessel, arranged at different levels, and both provided with a faucet at or near the bottom, a connecting-pipeextending from the receiving-vessel to a point at or near the bottom of the filtering-vessel, a sieve over the mouth of this connecting-pipe, and a stop-cock therein, aforaminous false bottom to the filtering-vessel, for supporting sand, gravel, or other filtering substance, and an outlet-pipe on the upper part of the filtering-vessel, in such a manner that the'liquid in the receiving-vessel may be admitted to the filtering-vessel in desired quantity, and is freedof suspended matter in passing therefrom, the same being filtered by ascension in the filtering-vessel,

. and being, moreover, uniformly distributed throughout the mass of filtering substance, whilcboth the receivin g-vessel an d the filteri n gvessel maybe readily flushed of any sediment collecting therein during the process of filtration. I

In the drawing, the letter A designates the receiving-vessel, B the filtering-vessel, and G D their faucets. E is the connecting-pipe between the two vessels, and Ia stop-cock in such pipe. G is the foraminous false bottom to the filtering-vessel, and H its outlet-pipe.

The vessels A B are preferably made to taper, the first in an upper direction and the second in a lower direction, and the first, moreover, is placed at a higher level than the other. The receiving-vessel A serves to hold the water or other liquid to be filtered, and may be made with a capacity of about one hundred and fifty gallons.

The pipe E leads from the receiving-vessel A to a point near the bottom of the filteringvessel B, thereby conducting the liquid from the receiving-vessel to the lower part of the filtering-vessel, in which latter it ascends to the outlet-pipe H. This pipe H is on the upper part of the filtering-vessel B, and may be arranged to conduct the liquid to a cistern or receptacle 'for storage. The fiow of liquid through the connect-ingpipe E is controlled by means of the stop-cock F.

In order to prevent suspended matter from entering the connecting-pipe E, I usually cover its mouth with a sieve, i.

The foraminous false bottom Gr is held in the filtering-vessel B by means of feet j, and upon the same is placed a' layer of gravel, sand, or other filtering substances up to or nearly up to the outlet-pipe H. so that as the water ascends in the vesselBit passes through such filtering substance. The liquid entering the filtering-vessel B fills the vacant space heneath the false bottom Gr, and being thus dis tributed ascends uniformly.

If it becomes desirable to cleanse or flush out either of the vessels A B, this may be readily accomplished by opening the faucets Oor D. These faucets-are of considerable importance, since without their use it is necessary to go through the tedious and impracticable operation of inverting the vessels A B in order to remove therefrom the impurities that will obviously accumulate therein during the process of filtration.

I am aware that an apparatus for filtering.

my invention, and does not show the prime] features employed by me in the construction of my filter, (which, as before stated, consists in a certain peculiar combination and arrangement of parts to form a filter, among which parts, essential to the effect sought, is cover ing the end of the .waterconductor which extends up through the bottom of the vessel A with a strainer and providing each vessel IOO with a stop-cock, so that the contents of either therein, said pipe being supplied with a suit-- may be drawn oft',) the same is hereby disclaimed.

What I claim as new, and desire to secure 5 by Letters Patent, is v The combination, in a Water-filter, of the two vessels A B, each provided with a stop-cock and located at different levels, of the pipe E, communicating with the vessel A through its 10 bottom and with the vessel B through its side below a foraminous false bottom arranged able cock, and having its end which enters the vessel A protected by a screen,.i, all substantially as herein shown and described. r 5 In testimony that 1 claim the foregoing I have hereunto set my hand and seal this 24th day of June, 1879.
