Description

F. DPPENSCHMITT.
CHAIN FABRIC.v
APPLICATION FILED JUNE 14 1913 A ttomw'y FRIEDRICH DPPENSCHMITT, OF PFORZHEIM, GERMANY.
CHAIN FABRIC.
Application led une 14, 1913.
To all fui/7mm it may concern.'
Be it known that I, FRIEDRICH DPPEN- scHirrrr, a subject of the German Emperor, residing at Pforzheim, Baden, in Germany, have invented certain new and useful Improvements in Chain Fabric, of which the following is a specification.
This invention relates to fabric composed of metal links, so-called chain fabric, such as is used for purses, hand-bags and the like, and the object of the invention is to provide a fabric of this class combining, with strength and comparative density, the quality of varying in pattern according to the degree to which it is stretched or relaxed while in use.
To this end I construct the fabric 0f series of rectangular' links, for example square links, alternating with series of intermediate circular' links, each rectangular link being engaged with four of the intermediate links, one at each of its corners.
The invention is illustrated in the accompanying drawing, in which Figure 1 is an elevation showing a piece of the fabric in its normal condition, and
Fig. 2 an elevation showing the same stretched.
Fig. 3 shows one of the square links, and
Fig. d one of the circular links.
The fabric shown consists of series of square links a alternating with series of circular links Z). The square links a are not interlinked with each other, nor are the circular links interlinked with each other, but each square link a, with the exception of those at the edges, is interlinked with four circular links b, and similarly each circular link (except at the edges) is interlinked with four square links a. When the fabric is loose, without strain in the direction of the Specification of Letters Patent.
Patented Nov. 20, 1917.
Serial No. 773,695.
series of links, a and b, the links in each series overlap each other, as shown in Fig. l. When the fabric is stretched, as shown in Fig. 2, the square links in each series lie end to end, or approximately so, but the sides of the square links always remain parallel or substantially parallel with the edges of the fabric, by reason of the fact that each square link, apart from those at the edges, is engaged at its four corners with circular links.
It will be noted, by comparison of Figs. 1 and 2, that there is a distinct change in the appearance or pattern of the fabric, when it lis loose and stretched respectively, the extent of the change depending on the extent to which the fabric is stretched.
TWhat claim as my invention and desire to secure by Letters Patent of the United tates is A chain fabric comprising, in combination, parallel series of rectangular links with straight sides, the adjacent sides of each pair of said rectangular links being adapted to contact with each other substantially throughout their entire length, and parallel series of circular links alternating with the first-mentioned series, the links in each of the several series having no engagement with each other and having endwise movement, whereby they may either overlap each other or may lie side by side without overlapping, each rectangular link being engaged with four of said circular links.
In witness whereof l have signed this speciiication in the presence of two witnesses.
FRIEDRICH DrrnNscHnrrr,
Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of Patents, Washington, '.D.
