IMPROVEMENT IN SODA-WTER FOUNTAlNS.

Specification forming part of Letters Patent No. 166,440, dated August 3, 1875; application filed January 29, 1875.

P To all whom 'it may concern:

Beit known that I, FREDERICK W. WIEsE- BROCK, of the city, county, and State of New York, have invented certain Improvements in Soda-Tater Fountains, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, and the letters of reference marked thereon, making part of this specification, in which is represented a vertical sectional view of my improvement.

My present improvement is essentially a new article of manufacture, and is an improved fountain for soda-water and other gaseous liquids, or for coniinin g gas or any other like medium.

The nature of my invention consists in constructin g thefountain out ofsheet-steel or sheetiron, and in then tinning the same, and after its several parts are soldered together the vessel is then heated, and its interior surface is coated with paraine, and which provides an exceedingly neat, light, strong, and durable fountain, and in which all danger of corrosion is, through the use of the parafline in connection with the tinning, securely guarded against.

The construction and operation of my invention are as follows: A isfthe cylinder. B is the upper end piece or top, and C is the lower end piece or bottom. These end pieces B C are each arched or dome-shaped, and are provided each with a broad well-dened hoop, as shown at B1 O1 of the accompanying draw ing. The top or end piece B is provided with an opening, b, at its center, and is as an article of manufacture the same as Burnetts milk-can breast, patented November 21, 1871, No. 121,154, and the article now manufactured under which patent I contemplate using as a top or end piece in the construction of my fountain, only making thel same of sheet-steel or sheet-iron instead of a heavier material. The bottom or end piece C is in form the same as the top B, only it is solid and without any opening at its center, and is provided with a foot rest or seat, O2. These severel features are constructed either of sheet-steel or sheetiron tinned. The cylinder is then riveted, and' the end pieces B O, and the bung B2, and the foot or seat O2 are all soldered together; or

the bung Bzmay be provided with a screwthread, and, after being passed through the opening b, may be secured by means of a nut, b', as clearly shownin the drawing. rlhe fountain, being thus constructed, is next heated, and its entire interior surface is coated with paraffine, whose well-known qualities, in connection with the tinning, will prevent corrosion, or the `fibers of the lnaterial being eaten or otherwise destroyed through the destructive action of any acid which the material which the fountain may contain, or of vwhich it may be used as a carrier, possesses.

I am aware that years since an e'ort was made to introduce a cast-iron fountain, the interior surface 'of which was first enameled or lined with porcelain or other similar vitreous matter, and then coated with melted paraine; but, owing to its immense weight, the attempt proved to be, comparatively speaking, a failure, and they have, owing to the great difficulty in handling them, in consequence of their weight, been almost entirely superseded by the sheet-metal fountain lined with blocktin. While fountains of this class-such, for instance, as the one embraced in my patent of April 6,1875, No. 161,845-operate successfully, yet they are expensive and laborious to manufacture, and, besides, are objectionable on account of their weight. Now, a fountain constructed according to my presentimprovement is much lighter than a fountain lined with sheet or block tin. It is far cheaper to manufacture thanl any fountain now known to the trade that possesses the same degree of strength. As the thin film of parafne fills up all the pores which may have ben left open in the process of tinning it is impossible that the acids which the water contains should corrode the metal. Now, I am aware that the process of coating metallic substances with parafne is not a new one; neither is the process of tinning sheet metal new. But neither of these processes, singly applied, could be successfully employed in the construction of a sheet-metal soda-water fountain. To attempt to coat the. interior surface of either a sheet steel or iron fountain-not cast metal, but sheet-with a thin film of parafine, and-without any other agent being employed, would be impl-noticable, because the para'ine would soon peel o", leaving the uncoated surface of the Inet-al exposed to the destructive action of the acids. Now, it would be equally as impracticable to attempt to use a sheet-metal fountain which is simply tinned, because as is well known to all who are practically familiar with the process of tinning either sheet iron or steel that it is impossible to so perform the process as not to leave certain of the pores of the metal uncovered or exposed. These exposed portions, coming in contact with the water or carbonio-acid gas, will soon become rusty and discolor the contents; but if the inside of the vessel is first tinned and then coated with parafne when heated7 as in my present invention, so as to melt the paratliue'on the tinned surface, the paraftine will enter all the pores and crevices, and, coinpletely lling the same7 render it impossible for the water or acid to rust the metal; and

as the coating of' parafne which I propose to use is designed to be not-hing` more than a merc filling,` up ot' the pores of the tinned surface, there is no danger of its peeling oft', in fact, the metal and parafne beco1ne as it were, so amalgamated that a very rough usage of the fountain will not wear ott' the saine.

Having now fully stated what I believe to be the condition ofthe art as applicable to my present improvement, what I claim as new7 and desire to secure by Letters Patent, is

A sheet-metal fountain tinned and coated with parattine, as a new article ot'manufacture.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
