MANUFACTURE OF SHEET-METAL SPOONS.
SPECIFICATION forming part of Letters Patent No. 232,832, dated October 5, 1880.
Application filed April 19, 1880. (N model.)
To all whom it may concern:
Be it known that I, PHILIP LEssoN, of Newark, New Jersey, have invented an Improvement in the Manufacture of Sheet-Metal Spoons, of which the following is a specification.
This invention relates to the method of making hollow-ware articles of sheet metal; and it has relation particularly to the method of forming the handles thereof and their relations to the bowls thereof.
The thing illustrated in the drawings is a sheet-metal spoon, but it is obvious that the bowl may be either a ladle-bowl, a saucepanbowl, a shovel-bowl, a scoop-bowl, or a bowl of any other shape than that of a spoon, and still the same method of forming the article he used and the same kind of a handle be pro duced.
In the drawings, Figure l is a blank for a spoon, punched out by a die or formed in any other usual way. Fig. 2 is a section on the line a2 g of Fig. 1. Fig. 3 is a section on the line to z of Fig. 1. Fig. 4 is a section on the line t o of Fig. 1. This original shape is stamped or cut of appropriate outline to form the desired article, and it will he noticed that it is a flat piece of metal, and that the outline in this case is that of a spoon-blank.
Fig. 5 is a top view of the spoon after it has undergone its second manipulation. Fig. 6 is a bottom view. A longitudinal indentation is made along the median line of the handle by a die, which throws down the metal, forming a groove along the center of the handle, extending into the bowl. Fig. 7 is a crosssection on the line a; y of Fig. 6. Fig. 8 is a cross-section on the line to z of Fig. 6. Fig. 9 is a cross-section on the line t o of Fig. 6 after this longitudinal indentation has been made along the median line of the handle.
The next manipulation is to close toward each other the flat parts of the handle, so as to bring the upper edges of the groove against each other, forming on one side of the handle a longitudinal seam and upon the opposite side a nearly-cylindrical projection, extending into the bowl and out to or toward the end of the handle.
Fig. 10 is a top view of the article after this third manipulation has taken place. Fig. 11 is a bottom view. Fig. 12 is a cross=-secti0n on the line a y of Fi 11. Fig. 13 is a crosssection on the the line to z of Fig. 11. Fig. 14 is a cross-section on the line 15 o of Fig. 11.
The fourth manipulation consists in hollowing the bowl to the proper shape, shaping the handle with its proper curve, and at the same time flattening the rounded projection which was left at the last manipulation.
Fig. 15 is a side view of the article after it has undergone this fourth manipulation. Fig. 16 is a cross-section on the line a: 3 of Fig. 15. Fig. 17 is a section on the line to z of Fig. 15. Fig. 18 is a section on the line 2. n of Fig. 15.
The result of this series of manipulations is to make a very stiff and strong article of sheetmetal hollow ware out of a single piece of metal re-enforced by folding upon itself along the median line of the handle, thus making a very efficient and desirable article having in parts which require great stiffness a triple thickness of metal, while in the bowl and along the sides of the handle there is but a single thickness of metal. It is obvious that this reenforce need not extend to the extreme end of the handle.
It willbe noticed that this process does not result in a mere beaded spoon, which is not uncommon, and which would have but a single thickness anywhere, but that the re-enforce is a triple thickness of folded metal, which I believe to be new.
Having thus described my invention, I claim and desire to secure by Letters Patent of the 8 5 United States- 1. As an improved process of manufacture, the series of manipulations described for formin g an article of sheet-metal hollow ware, consisting of cutting a blank of approximate outline, of indenting said blank longitudinally, of closing toward each other the non-indented parts of the blank, and of flattening toward the non-indented parts the parts originally indented, substantially as described.
2. A handle for hollow ware made of one piece ofsheet metal folded in three thicknesses, one surface of which handle is seamed along its median line by the approximation of two folded edges of the sheet metal, substantially me as described.
PHILIP LESSON.
