METHOD OF MAKlilG ORNAMENTED ARTICLES OF SOFT SHEET METAL.

Application tiled March 8, 1553.

.50 (til whom, it may concern.-

Be it known that I, J. ALVIN EAIDES, of Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Making Ornamented Articles of Soft Sheet Metal; and Il. do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Like letters in the figures indicate the same parts.

My improvement relates to articles made of soft sheet metal having complicated or irregir lar formssuch as napkin-rings, tableeasters, pitchers, tea-pots, and thelike, which, among other designs are very commonly provided with ornamental bands around them alternat ing with plain metal surfacesand to new methods of manufacturing the same, of which the following is a description, retercnee being had to the accompanying drawingf-i, in which I have represented a napkin-ring and a small cup as being the simplest articles with which to illustrate myinvention.

Figure 1 shows an end and side view of a cylinder of metakwhich may be called a napkin-ring blankfl 'the side view, a, showing the ornamentation applied to the blank before spinnin Fig. 2 is a side view of the napkinring spun into shape after the ornan'icntation has been applied to the cylinder or blank, having the exterior ornamental bands in allerlhg. 3 is a view of a ring of similar form shown in longitudi nal section as made up by the old method in separate sections, the soldered joints being shown in heavy transverse lines. Fig. a represents a Hat disk of metal ornamented upon one side before being spun. 'Fi g. 5 represents a cup spun into shape from such an orna niented disk. Fig. 6 represents the body of a tea or coffee pot spun from a straight tube or cylinder after three ornamental bands have been imprinted upon it, the three bands being made by the use of thcsame ornamcntingroll.

Articles of this class have been heretofore l lo. 309,531, Beeember 23, 188%.-

made of separate rings or parts, some of such par '2; being rolled with an ornamental pattern, and some plain, all of which have been separately formed to their required shape and then soldered together to form the complete article; and also in some instances the bands, after being ornamented, have been soldered upon the outside of the plain surfaces of articles. The rolling of an ornamental band elongatcs or stretches the metal, and for this reason such parts have been made separate, so that when bent round and the ends united by soldering it should unite with and be of the same size as the adjacent plain portions; also the proper form has been given to these ornamental bands by driving them onto a block or former of the desired sectional shape, in order not lo injure the figures of the design, while the plain portions of the article have been spun into shape. This method of making such articles by uniting the bands of plain and ornamental work after their shapchas been given to them is a very laborious process, and requires skilled workmen, and even then the united joints are not always true and perfect.

The object of my invention is to make a much more perfect article by spinning the bodies into shape from one piece 01" metal after the ornamentation has been applied thereto.

1 have discovered that the ornamentation can be rolled or otherwise imprinted upon a sheet or disk of plain metal so as to cover only a portion of its surface, or that such ornamentation can be rolled or otherwise made upon a portion only of atubular or cylindrical surface, and the whole then spun into any shape desired in substantially the same manner as plain metal.

In the accompanying drawings, a, Fig. 1, is an end view of a cylinder or napkiirring blank. a is aside view of such blank, show;

ing ornamental bands applied thereto.

Z) denotes the ornamental bands, and c the plain bands, in each of the figures.

d, Fig. 3, denotes the joints where the several bands are soldered together when the ar ticles are made by the old method.

of g, Figs-4t and 5, respectively, denote the same ornamentation on the disk before spinning, and on the cup spun therefrom, and p the unornamented portions.

h i 70, Fig. 6, are ornamental bands on dif ferent portions of a tea-pot body illustrating the change produced by the spinning operation upon figures originally imprinted upon a straight cylinder by the same ornamentingroller.

In my improved method of mai'iufacture, when an ornamental band is rolled upon a plain surface, the metal being held from elon gating by the plain metal upon each side, it bulges upward and becomes somewhat distorted but this can be readily rolled or pressed down, so as to present a flat surface again. The whole can then be spun into the shape desired according to the usual method. For this purpose I use a wooden tool, and fill the ornamental designs with soap, so that the pat tern shall not be injured or disfigured during the spinning operation.

By means of my improved method of ornamenting plane or cylindrical surfaces of soft sheet metal, and afterward spinning the metal into the form of the ring, cup, tea-pot, or other article desired, I am enabled to pro duce a great variety of different forms of fig ures upon the finished articles by the use of only a few different designs upon the orna- 1nenting-rolls. For instance, by imprinting several ornamental bands with the same roller upon different portions of a plain cylinder or tube, and afterward spinning the cylinder into the form of a tea-pot having alternating swelled or bulged and contracted portions throughout its height, shown in Fig. 6, the spinning operation will in some portions of the article lengthen out the ornamental figures and contract their width, as at t, Fig. 6, while in other portions of the article the figures will be expanded in width and contracted in length, as at 7 Fig. 6, which gives the finished article the appearance of having been ornamented by a variety of rolls with a different figure out upon each; and also by means of my improvement articles which have heretofore been made in several parts can be made of a single piece and present a much more finished appearance than is now possible, at the same time dispensing with the clumsy and heavy, as well as unsightly, solderedjoints, and leaving the articles smooth and uniform in all their parts.

In the manufacture of deep hollow vcsselssuch as pitchers, coffee and tea pots, &c .-it will be found more advantageous to first spin frusta of cones with one end closed, then to apply the ornamentation, and afterward to spin these cylinders into the requisite shape; but when making shallow articlessuch as cake-baskets, cups, caster-bands, &c.the ornamentation may be applied to the fiat disks of metal, which afterward are spun into the shape desired.

The ornamentation may be applied to the sheets or cylinders of metal by any of the wellknown means; but I have found the most ecothereon the counterpart of the design upon the periphery of the rolls.

The method of producing ornamental designs on sheet-metal articles suggested in the English provisional specification of Thomas WVhite, No. 1,757, of the year 1879, I have found upon trial to be wholly impracticable, for the reason that composite sheets of metal produced by soldering cannot be fashioned into articles by spinning, because this operation tears apart the separate pieces of metal united by solder. On the other hand my method is practiced by the employment of homogeneous sheets of comparative] soft metal, and the operation of soldering is wholly dispensed with in the article so fashioned.

What I claim is 1. The art or process of making ornamented hollow articles with the bodies formed from a single piece of sheet metal without soldering by, first, ornamenting the surface ofa plain cylinder or other tubular form of metal, and, second, spinning such ornamented cylinder into the shape desired forthe articleto be produced, substantially as described.

2. The art or process of making ornamented hollow ware from one piece of sheet metal by, first, ornamenting the surface of a disk of metal, and, second, spinning such ornamented disk into the shape of the article desired, substantially in the manner described.

The art or process -of making soft sheetmetal hollow ware with ornamented homogeneous bodies complete without soldering by ornamenting the metal before final shaping, and subsequently spinning it into the ultimate shape of the article desired, substantially as described.
