STOCKING.

Specification of Letters Patent. Patented July 29, 1919. I

Application filed January 27, 1916. Serial No. 74,565.

To all whom it may concern: 1; 7

Be it known that I, RiOHARD THIERFELDER, a citizen of the United States, residing" at Milwaukee,in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Stockings, of which the following is a full, clearfconcise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to the manufacture of stockings and is concerned with the production of a stocking of characteristically new and advantageous construction.

The special feature of my invention lies in placing the seam, whereby the edges of the manufactured fabric are joined, upon the normal outside of the stocking. The novelty of the method lies in features concerned with the disposition of the seam upon the normal outside of the stocking.

In sewed stockings, that is, the type of stocking wherein the piece of fabric from which the stocking is to be formed is preliminarily manufactured and subsequently sewed together at its edges, the seam, in prior art devices, is disposed upon the inside. It is well known in the art that the most desirable fabrics'for this purpose tend to curl inwardly, and for this reason, up to the present time, the only practical method has been to sew the stocking in reversed condition, that is, inside out, and then turning the stocking to give it its normal form, thus bringing the seam upon the inside. Incident to this plan and the product which it produces is the consequent discomfort of the wearer. According to the teachings of my invention, I sew the stocking in its normal condition, that is, outside out, notwithstanding the fact that the material tends to curl inwardly, and, since I provide the method and means for taking care of this inward curl, when the curls are placed face to face instead of back to back, I am enabled to produce a stocking with the seam upon the outside.

My invention will be more readily understood by reference to said drawings, in which- Figure 1 is an elevational view of my improved stocking;

ig. a is a more or less diagrammatic view, being; a seat-ice reissues the plans of the line 2'-2 of Fig.1, and looking in the direction indicated by the arrows before the sole of'thestocking is sewed; I

Figs. 3, 4:, 5 and6are more or less diagrammatic views illustrating the margins of the fabric in the various stages of manufa'cture; and

' Fig. 7 is an enlarged fragmentary developed view of the toe portion of the fabric in fiat form before thev outer edges are sewed together.

It will be unnecessary to illustrate or de scribe the sewing machine which I use for sewing the edges of the stocking together except as to the peculiar guides which I use to force the curled up edges to uncurl and to lie fiat against each other in position to be sewed through and through together.

In said drawings 1 is my improved stocking as it appears in finished form, having a seam 2 sewed around the toe portion 3 and the sole portion 4:. Fig. 7 illustrates the toe portion 3 in flat condition before the edges have been sewed together, and the purpose of my invention is to provide an improved manner of sewing the edges 5 of the. stocking blanks together to form the finished stocking as shown in Fig. 1.

I provide a guide mechanism which I have illustrated merely diagrammatically in the several figures.

Fig. 2 shows how the margins of the piece of fabric, curling inwardly, are brought together for stitching. I provide a central guide member 14:, and outer guide members 18. The guide members are spread apart, and one margin of the fabric is led between one of the outer guide members and the central guide member while the other margin of the fabric is led between the other external guide member and the central 1nemher, so that the two margins embrace the central guide as shown in Fig. 3. The marginal curls first encounter the primary spreaders 23, 23, on the upper edge of the central guide, as illustrated in Fig. 3, which spreaders wedge themselves into the curls to straighten out the fabric, as shown in Fig. 3. The secondary spreaders 24, 24 are higher than the primar spreaders and their action is to further t e action of the primary is readers, thus further straightening out the Lebric, in Fig. 4.. The step is illustrated in Fig. 5 where it will seen that the two margins are in straightened condition between the respective guide 7 members and after passing these guide members the two margins are brought face to face, as illustrated in Fig. 6, and led between the rolls C, C. As shown, the edges extend upward beyond the tops of the rolls and the slight remaining margin is that provided for stitching purposes, it being seen that the reciprocating needle D lies immediately above the rolls. The stitching then takes place and the stocking is finally formed, right side out, with the seams on the outside;

It will now be clear that I have provided a stocking made up from a knitted blank, the

edges of which tend to curl inwardly and in which stocking the seam joining said edges appears upon theoutside of the stocking.

A stocking conipo'sed of 'a fabric blank, the margins of which tend to curl toward the wrong side f the fabric and inwardly of the stock ng and having said margins disposed together face to face and joined by stitching tl16IGtl1lOUgh,;tl'lG margins thus being on the outside of the stocking.

In witness whereof, I hereunto subscribe my name this 21st day of January, A. D.
