Specification of Letters Patent.

Patented May 8, 1906.

vApplication filed August 14, 1905. Serial No. 274,141.

To @ZZ whom it may concern.-

Be it known that I, HENRY TYRELL, musician, of the city of Ottawa, in the county of Carleton, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Filters; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in filters for water and like liquids; and the objects of my invention are to provide a filter of cheap and simple construction which at the same time as filtering the water will cool it without the filtered water coming in contact with the cooling-ice, further objects being to insure that the liquid going through the filter is perfectly filtered 5 and it consists, essentially, of an outer and inner vessel having an ice-containing chamberl provided between them, a plurality of telescopic filtering-trays secured in the top of the inner vessel, and a faucet suitably connected to the inner vessel, the various parts of the device being constructed and arranged in detail as hereinafter more particularly described.

The drawing shows a sectional view through the filter.

In the construction of water-filters it has been common to place the cooling-ice directlyin contact with the water` to be filtered, and it is obvious that this introduces a number of impurities to the water which afterward must be removed. In my invention the ice is so applied that while cooling the water with equal ease it does not come in contact therewith at all.

Referring to the drawing, A is a filtering vessel comprising an outer vessel c and an inner vessel a', set therein in such a manner that intercommunicating ice-containing chambers a2 a3 a are provided between the two vessels. It will of course be understood that the ice-containing chambers extend all around the inner vessel, so that the water contained therein will be perfectly cool. These vessels may be of any desired shape in cross-section. A discharge-pipe a4, provided with' a faucet a5, is connected to the inner vessel, extending to the outside of the filter. Chamber-covers a c7 are provided for te T e chamber a3, provided at the front of the filter, extends only part way up the side of the outside vessel a, and the top as thereof forms a shoulder, the purpose of which will hereinafter appear. The ice a9 or other cooling ing-sponge b2 is secured. Charcoal b3 orY other suitable filtering or purifying agent is placed in the bottom of the tray. A second tray C, of slightly smaller size than the tray B, is provided at the top with an outwardly-extending flange c, which abuts the top of the tray B and s upports the tray C in position with the bottom thereof a short distance above the bottom of the tray B. Perforations c are provided near the center thereof, and a number of fine pebbles c2 are placed in the bottom thereof. On top of the tray C a third tray D rests, having at the top a flange d, which rests on top of the tray C, and so supports the tray D in position. A

plurality of perforations d are provided in vthe bottom of the tray, and pebbles d2 of a larger size than those contained in the tray C are placed in the bottom thereof. A fourth tray E is placed on top of the tray D, having a fiange e resting on the top thereof. Perforations e are provided in the bottom thereof, and the unfiltered liquid is poured into this tray.

In order to use my filter, the unfiltered water is poured into the top tray E, from whence it gradually trickles through the four trays into the lower compartment c', being thoroughly filtered on its way by the passage through the fine stones, charcoal, and sponge. The ice nearly surrounding the bottom of this chamber quite effectually cools the water contained therein, and it will be seen that no contamination will be given to the water by the ice coming in contact therewith.

It will be understood that in carrying out the construction of my device certain changes may be made in the details thereof without materially departing from the spirit of my invention.

What I claim as my invention is- In a filter the combination with the outer IIO and in'ner Vessels of an ice-containing chaml faucet connected to the bottom of the inner ber extending between the tWo Vessels at the i vessel as and for the purpose speeied. lo back and bottom and partially up the front, Signed at the city of OttawaI in the Provthe top thereof forming a shoulder and a perinoe of Ontario, this 11th day of August, 1905.
