UNITED STATES' PATENT OFFICE.

M. W. WARNE, OF ST. LOUIS, MISSOURI.

FILTER.

Specicaton of Letters Patent No. 30,366, dated October 9, 1860.

To all 'whom fit may concern:

Be it known that I, M. W. WARNE, of St. Louis, in the State of Missouri, have invented a new and Improved Filter; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is a sectional elevation of my invention taken in the line w, w, Fig. 2. Fig. 2 a horizontal section of the same, taken in the line y, y, Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in arranging the parts of a filter in such a manner that the water will pass through a proper filtering medium and cause the impurities to settle at the bottom, the filtering medium being placed within suitable boxes or receivers in a cooler and used in connection with iron and sulfur so that the water while being purified and cooled will also be medicatedthe whole being arranged as hereinafter fully shown and described, so as to form a portable, efficient and improved article of the class specified.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A represents an ordinary water-cooler, the same being a sheet-inetal receptacle provided with double walls filled between with charcoal or other good non-conductor of heat. This cooler is provided at its lower part with a faucet B, and within the cooler there are placed three upright sheet-metal cylinders O, D, E, two of which C, D, may be filled with the usual filtering material, to wit, sand and charcoal F. The other cylinder E, has its lower part provided with sand and charcoal F, and its upper part provided with sulfur G, and iron II, the latter being in the form of nails or other small articles, see Fig. l. The two cylinders O, D, communicate with each other at their upper ends as shown at a, and the two cylinders D, E, communicate with each other at their lower ends as shown at b. The cylinder E, has a pipe H, which passes from its upper end downward within the cooler to the faucet B, and the lower end of cylinder O, communicates with the interior of the cooler A, by an opening c.

The water being placed in the cooler A,

and the faucet B, turned and opened the water will pass up through cylinder C, and through the connection a, to cylinder D, and thence down cylinder D through the connection Z2 to E, and up through E into the pipe Hf, and down H into and out through the faucet. By this arrangement the impurities taken from the water in its passage through the liltering medium will have a tendency to settle at the bottom of the cylinders, the medium in the upper parts of the cylinders being thereby kept pure. The water it will be seen will How from the cooler until it reaches a level with the opening c, and the cylinders being immersed in the cold water and surrounded by ice will not of course admit of the temperature of the water rising as it is filtered.

The sulfur and iron medicate the water and render it essentially the same in effect as many of the natural mineral springs which have proved so beneficial in many diseases.

vThe sulfur and iron may be placed in either of the cylinders, and perhaps it might be preferable to place it in the one the water first enters, in order that the filtering medium through which the water afterward passes may take away any superabundance of mineral matter the water miOht take up.

Any proper number of cylinders may be used, one or more, but for ordinary purposes, three will probably be a preferable number.

I would remark that the end of faucet B, should be below the opening c, of cylinder C, in order to form a siphon. If the faucet does not extend below c, a flexible tube may b e attached to its end and perhaps this would be preferable as it would not interfere with the device being placed on any table or bench whereas if the end of the faucet B, projects below the bottom of the cooler the latter could not be placed far back on any support.

Having thus described my invention what 4I claim as new and desire to secure by Letters Patent, is:

The employment or use of cylinders C, D, E, one or more placed within a water cooler A, and provided with a suitable filtering medium F, and iron and sulfur H, G, essentially as and for the purpose set forth.
