NEW YORK, 1% Y., A CORPORATIQN OF NEWiERSEY.

ill-SIDED CURVED-WALLED VESEEL.

Application filed December 1, 1913. Serial No. 803,874.

To all whom it may concern: Be it known that I, JOSEPH DISTER, a

citizen of the United States, residing in Walled Vessels, of which the following is a specification.

This invention relates to an improvement in the art of transparent sided'curved walled vessels, and the invention consists in making the walls of the vessel of a sheet metal blank into which isset a flexible transparent window seamed into place while the sheet is in the-flat and thereafter curved into form and finished; and in the product or finished article thus 'made, 7

In the accompanying drawing which forms a part of this specification, Figure 1 is a section of the sheet metal vessel Wall shown in the flat and formed with an aperture having shouldered edges ready to receive the flexible transparent sheet; Fig. 2 is a similar section with the flexible transparent sheet added and showing the shouldered edges turned down solidly upon sa1d transparent sheet; Fig. 3 is a similar sectional view of the composite wall showing the salne curved into form and its ends united by a side seam; and Fig. l is a view of the completed vessel.

Heretofore, the worker in sheet metal, in the manufacture of the large line of articles, like cracker boxes, candy boxes and display boxes in general, that require to have a transparent side through which the con:

tained goods may be seen, has felt obliged to make the vessel containing the transparent window with a flat side and this has generally resulted in such packages or vessels being made of a rectangular term, involving the expense or manufacture cident to such rectangular form and relativ greater than the cost of making the cylind "c or curved form 011'. vessel. in the present invention a means is offered whereby such vessels be made with curved walls following in the main the usual processes employed in the manui acture of cylindric walled sheet metal ware.

In the said drawing, A is a flexible sheet of tm such as is ordinarily used in the manufacture of tin cans and sheet metal ware. This blank, while in the flat,-is perforated with a large window aperture B, the edges of which are folded outwardly to form the double thickness C, and the shoulder flange D. The ends of this blank are formed with the usual hooks E, E, to unite them together. While thus still in the flat a transparent sheet of flexible material F, as for example transparent celluloid cut to the right form and size, is laid into the seat formed by the shoulder flange D, and said shoulder flange is then turned down solidly upon it, after which the sheet is in such condition that it may be and is curved into the form shown at Fig. 3 of the drawing, the ends of the sheet being seamed together to form the body of the vessel which is afterward provided with a bottom G and top of suitable character, v

The blank, flat sheet, provided with its flexible transparent portion flatly seamed to it, as above described, is in condition to be and is treated by processes of manufacture the same asthough it contained notransparent window, which fact greatly cheapens the cost. And the finished article is cheap, strong, and much less liable to breakage than the ordinary rectangular transparent sided sheet-metal vessel.

It will be noted that owing to the nature I of the transparent flexible material, preferably celluloid, and to the method of securing She t of metal and a sheet of flexible.
