PROCESS OF PRODUCING STOCKINGS ON FLAT KNITTING FRAMES Filed May 7, 1928 Patented Jan. 14, 1930 UNITED STATES PATENT! OFFICE? CURT HILSCHER, OF CHEMNI'IZ, GERMANY PROCESS OF PRODUCING STOC KINGS ON FLAT-KNITTING- FRAMES Application filed May 7, 1928, Seriai No. 275,916, and-in Germany lune 5, 1925.

This invention relates to a process of producing socks and stockings in one operation so that to the lower ortion of the heel of the stocking a pouch-like widening is given.

5 Care has to be taken that the well knowninner transferring line which limits the heel is preserved in its usual shape. Without preserving this line a widening by means of two needles would be suflicient to obtain the heelwidening over the entire lower portion of the heel. The Widening in preserving the inner transferring line of the heelis obtained, according to the invention, by transferring every two rows of, loops from the beginning of the heel on both sides of the fabric in outward direction, first by one needle, whereupon the travel of the thread-guide is lengthened in outward direction by two needles. As soon as the border-loop has been completed, for which two rows are required, the heel has been widened during the knitting of these two rows by two needles, one needle-widening by the transferring and asecond needle-widening for which the thread-guide has travelled beyond the widening needle. On the inner boundary line ofsthe heel only. the transferring is effective and not the widened travel of the thread-guide. ihe lower portion of the heel is knittedin this manner whereupon the widening-of the travel of the thread-guide is stopped and the transfer points continue to transfer, in a manner'known per se, a narrower piece up tothe upper end of the heel.

The process is illustrated, by wayof example, 'on the accompanying drawing which shows in the only figure a stocking as'itcomes from the knitting frame.

As soon as the knitting from the heel-portions II and III continuing the legl and the middle portion IV begins, the heel is transferred in outward direction at either side of the fabric by one needle with the transfer points extending from theinner boundary inc 0 the heel to the maximum heel-width. The thread-guide. Whichfollows then moves in outward direction a distance of two needles more than in the preceding row 9 whereupon a second row is knitted, in order to finish the loops, specially on the edge. The; transfer points begin then to work again andishift the knitting of the second row, the widening by one needle, followed by a widening by a second needle through the lengthened travel of the thread-guide byctwo needles and so forth takes place, until to the heel a special widening has been given in its lower a to a and from f to b (Fig. 1).

From now on the travel of the threadguide is not lengthened any more, thewidth of travel remaining the same to the end 0 and portion from Z of the heel. A number of the transfer points are now rendered inoperable while the remaining transfer points work from the looprow a to b on only the narrower row :0 of the heels after each row by one needle in outward direction up to the ends 0 and d of the heel-portions.

A pouch-like widening is given to the heelportions II and III by this proceeding, said widenings being indicated on the drawing by the triangles e, a, g and f, b, h, the inner boundary line of the heel being preserved in a manner known per so.

I claim A process of producing stockings with widenedlheel-fiortions on the flat knitting frame in whic widening takes place up to the o btention of the maximum heel-width,

consisting in making from the beginning of theheel-portions first transfer by the transfer points the 'heelloops by one needle at either side of the fabric in outward direction,

inthen lengthenin the travel of the threadguide by irwo need es, in transferring in outward direction'again by one needle after two rows of loops have beenknitted, in lengthening the travel of thethread-guide by two needles until a pouch-like widening of the heel has been obtained, in continuing then the travel of the thread-guide in the same width, and in'making the transfer points con tinue to work only in the width up to the end of the heel.

In testimony whereofI aflix my signature.
