$PECIFICATION forming part Of Letters Patent NO. 636,752, dated November 14:, 1899.
Application filed May 10, 1898. Serial No. 680,245. (No model.)
To all whom it may (fifim;
Be it known that I, TRISTRAM D. BROWN, of Oanandaigua, Ontario county, New York, have invented certain new and useful Improvements in Bottoms for Sheet-Metal Vessels, of which the following is a specification.
My invention relates to improvements in sheet-metal vessels, particularly to that class known as non-corrosive or antirustf and the object of the invention is to provide means for securing a non-corrosive bottom in a vessel without the necessity of using a second bottom plate, usually of thinner materail, or turning or seaming the edges of the non-corrosive bottom over or around the lower edges of the walls of the vessel, thereby'preventing the cracking or peeling of the noncorrosive substance with which the bottom may be coated at the point where the. metal is usually bent over the edges of the walls and permitting a much heavier material to be used for the bottom plate than is commonly employed, thus increasing the life of the vessel.
A further object is to provide means for protecting the lower edges of the walls of the vessel and preventing the same from rusting, particularly when used as a cream-pail, the lower end then being immersed in water.
' To this end the invention consists in pro-" viding a sheet-metal vessel having a single non-corrosive bottom with a locking band or ring, said band being folded over the lower edge of the walls of the vessel and secured also to the vessel-bottom.
Further, the invention consists in providing a sheet-metal vessel with an exteriorlyarranged non-corrosive band or ring having one edge secured to the bottom of the vessel and its other edge folded over the lower edges and seamed to the walls of the vessel.
Further, the invention consists in various bottom plate and locking-band being shown detached therefrom. Fig. 2 is asimilar view showing the parts assembled. Fig. 3 is a-sectional view of the lower end of a completed pail. Fig. 4 is a plan view of the locking band or ring.
In the drawings, 2 represents the walls of a sheet-metal pail having at its lower end the usual outwardly-turned flange 3, the walls being flared slightly to receive the bottom plate 4, preferably of heavier material than the walls of the pail or vessel, and composed of or coated with a suitable non-corrosive substance. A downwardly-turned flange 5 is preferably formed at the edge of the bottom plate, said flange being preferably outwardly turned at its edge to restupon the flange 3, so that the whole bottom plate fits snugly into the lower end of the pail or vessel in which it may be placed.-
In non-corrosive sheet-metal vessels as usually constructed two bottom plates are provided, the upper being composed of or heavily coated with a non-corrosive substance, while the lower or sustaining plate is of thinner metal, usually tin, and havingits edges folded over and seamed to the lower walls of the vessel. Usually the two plates are secured together at or near the center by'a process which adds materially to the expense of manufacturing the article. The use of the second plate was found necessary, as a heavy single bottom could not be folded at its edges to seam the bottom to the vessel without cracking and peeling off the heavy coating of noncorrosive substance with which the bottom plate was covered. To obviate this difficulty and to do away with the-expense of a double bottom, I provide a locking band or ring 6, preferably of zinc or other non-corrosive material, having oppositely-turned flanges 7 and 8 and nesting within the flange 5 on the bottom plate. The flange 8 rests upon the surface of the non-corrosive bottom and is secured thereto, while the flange 7 is turned over the edge of the bottom plate and seamed to the lower walls of the vessel. Instead of zinc any other suitable sheet metal may be used for the locking-band and coated with a non-corrosive substance or not, as preferred. The band or ring fits neatly within the flange 5 and over the outwardly-turned edges of said flange, concealing any exposed part of the surface of the bottom plate where the noncorrosive substance may have cracked or peeled oif in forming the flange 5, thus preventing the plate and walls from rusting and holding the parts firmly together and at the same time presenting a neat and finished appearance to the bottom of the pail or vessel.
The advantage of placing the non-corrosive bottom in a sheet-metal vessel in the manner heretofore described lies in the fact that I am able to use a single bottom of very heavy material, heavily coated with non-corrosive substance,which would not be practicable in pails or vessels as heretofore made, as the coating would crack and peel off at the point where the fold was made over the edges of the vessel, making it necessary to use a second thinnersustaining-plate, the edges of which could be folded without breaking the coating.
My improved construction does away with the necessity of two bottoms in the vessel, thereby effecting a considerable saving in the cost of manufacture, and by its use I am able to use a much heavier bottom plate than is ordinarily employed, thus increasing the life of the pail or vessel and also thoroughly protecting its lower edges from rusting by means of the non-corrosive locking-band, the use of said band rendering the device particularly adapted for cream-pail construction where the lower end of the vessel is always entirely immersed in water when the pail is in use and is therefore directly exposed to the action of rust.
I have shown the device used in connection with a pail; but it is obvious that the same construction may be employed in the bottoms of boilers, basins, and a great variety of other sheet-metal vessels, and this construction maybe employed in the manufacture of ordinary tinware, particularly when it is desired to use heavy material for the bottoms of the vessels, and while I have shown and described but one form of locking-band and but one method of securing the parts together it is obvious that various modifications would suggest themselves to any one skilled in the art, and I do not therefore confine myself to the exact details of construction shown herein.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As a new article of manufacture, a sheetmetal Vessel provided with relatively thin walls and a relatively thick bottom and with a non-corrosive band or ring, folded over the lower edges of the walls of the vessel and secured to the vessel-bottom, substantially as described.
2. As a new article of manufacture, a sheetmetal vessel provided with relatively thin walls and a relatively thick bottom and with anon-corrosive band or ring folded over and adapted to conceal and protect the lower edges of the walls of a vessel and secured to the bottom of the vessel, substantially as described.
3. As a new article of manufacture, a sheetmetal vessel provided with relatively thin walls and with a single relatively thick noncorrosive bottom, and a band or ring folded over and seamed to the walls of the vessel and secured to said bottom, substantially as described.
4. A sheet-metal vessel, comprising relatively thin walls or sides, a single relatively thick non-corrosive bottom, and a non-corrosive locking band or ring having one edge folded over the lower edge of said walls and its other edge secured to said bottom, substantially as described.
5. In a sheet-metal vessel, the combination, with relatively thin walls and a relatively thick non-corrosive bottom, of a band or ring provided with oppositely-turned flanges, one secured to said bottom and the other being folded over the lower edges of the walls of the vessel, substantially as described.
6. The combination, in a sheet-metal vessel, with relatively thin walls and a relatively thick non-corrosive bottom having a downwardly-turned flange at its edge and fitting within the lower end of the vessel, of a noncorrosive band or ring fitting within the flange upon said bottom, and having oppositely turned flanges one being secured to said bottom and the other being bent over the lower edges of said wall, substantially as described.
7. In a sheet-metal vessel, the combination, with relatively thin walls 2 having a flange 3, of a relatively thick non-corrosive plate I having a flange 5 and adapted to fit within said walls 2, and a non-corrosive ring 6 fitting within said flange 5 and having flanges 7and 8, the former being folded or turned over the edges of said flanges 3 and 5 and the latter being secured to the under surface of said plate 4, whereby the same is locked in the lower end of said vessel, substantially as described.
In testimony whereof I have hereunto set my hand, this 30th day of April, 1898, at Canandaigua, New York.
TRISTRAM D. BROWN.
In presence of THEO. PERKINS, J. R. MOLAUGHLIN.
