IMPROVED WATER-GOOIER.

til fizlgrhule mum in in than some finial me making part at In time.

TO ALL WHOM IT MAY CONOERNi Be it known'that I, JOHN L. HADDEN, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvementin the Portable Sheet-Metal Water-Cooler; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had te the accompanying drawings, making a part of this spe'c'ificatiomin which-1 i v I Figure 1 is a vertical central section of the lower end of the inner cylinder of a portable sheet-metal watercooler, having my improvement applied thereto, and v Figure 2 a plane view of the bottom of the said cylinder 7 Like letters of reference indicating the same parts when in both figures. V l

The object of myimprovement is to render the sheet-metal bottom of the inner cylinder of a cooler secure against being broken through, cracked, indented, or otherwise injured by'the dropping of the ice-lumps into the cylinder, in replenishing it; and my invention consists in corrugating the said bott'om'so as to give it the raised or general conical form, substantially as hereinafter deseribednnd set'forth.

Referringto the drawings, Ais theusunl body or vertical sides of the inner cylinder of a cooler, and B. the improved corrugated conical bottom of the same, the faint lines in fig. 1 indicating the usual external cylinder and foot-flange. i I

I Thebottom, B, is formed by taking a fiat disk of the sheet metal, (iusually sheet iron',) and, by means'of a pair of stamping-dies, giving it the general conical formdand the corrugations b bradiating from its centre, as represented in the drawings. It is then secured,'with its raised or conical side upward, to the lower end 'oi' the cylinder A by means of the usual interlapping sea-m a, substantially as represented in fig. 1, and,-finally, the

.whole cylinder and bottom together (if of sheet iron) galvanized or coated with zinc in the usuaIwell-knovvn manner. I It will be seen that the conical corrugated form, described as given to the botto'm,rB, will greatly increase its strength, and resistance to injury from the falling lumps of ice, insupplying the cooler therewith.

I-have applied a concave-convex bottom, of: cast iron, to the inner cylinder of a portable water=cooler for the samepurpose, but find from experience that it is very liable to be.broken by the fallinglumps of the ice unless made so thick/ as to be both too costly and too heavy; and therefore have invented and applied the corrugated conical sheet-metal bottom herein described, and find that it efi'ectually meets the requirements of durability,

lightne'ss,-and inexpensiveness;

Having thus fully described my improvement, and shown its utility, what I claim as new, and desire to secure by Letters Patent, is confined to the following, viz:

I claim a sheet-metal water-cooler, having the bottom, B, of its inner cylinder, A, made of sheet metal,

raised and corrugated substantially as described and shown, for the purpose specifiedl JOHN L. HADDEN- Witnesses r BENJ. Monrson, JonN WHITE.
