Another course 26 is then added and ting of the stocking, that is from the top to the stitch cast oil from the needle 12 will be the tip, but in some cases, and in fact most drawn out, as indicated at '28, and cast onto the cases, the stocking is knit from the bottom up, needle 38. Another course 29 being knitted, the F loop cast oif'from the needle 30 will be drawn out, as indicated at 31, and cast onto the needle 34. This will be continued .until thedesired width hasbeen attained, each widening being confined to its own bank of needles.

The widening may take place following any predetermined number of knitted courses, depending upon the abruptness of widening found desirable. The illustration at Figure 3 is not, therefore, intended to govern in all cases, but is merely illustrative. It will be understood that Figure 3 is the view from the wrong side of the knitting, at one end of one bank of needles of the Lamb type machine, the original cast on stitches 8 being indicated as cut apart and the dotted connecting lines indicating their original relation. This is necessary for the reason that showing the widening stitches for both banks of needles would otherwise show the stitches 8 only in end elevation. The corresponding end of the opposite bank will, of course, be similarly treated, while the opposite ends of the banks will be likewise treated.

It will be understood, of course, that the widening by the drawing out of the stitches, as disclosed, will be effected .alternately at opposite ends of the banks and at opposite banks at the opposite ends to give symmetry to the knitted article.

It will also be understood that Figure 3 is purely diagrammatic, and that the knitted article will not, in fact, have the appearance as at Figure 3, for the reason that the drawing out of the cast ofi stitches, as indicated at 35, 28 and 31, will distort the surrounding stitches, drawing them into a more compact relation whereby greater strength is attained at the line of widening.

Figure 2 illustrates the method of narrowing in case the stocking is knitted downward, and in that case, the loop on the outer needle 23 will be transferred across the loop on the needle 24 to the hook of the needle 25 in the direction shown by the arrow. 1

By this method of widening or narrowing, I obtain a fabric which is considerably stronger at the width changing point and one which will not have the large openings or holes inherent in the present methods of manufacturing this type of goods.

Of course, the stocking illustrated may be modified in various ways without departing from the invention herein set forth and hereafter claimed.

The invention'is hereby claimed as follows:

l. The method of widening during the production of fabric upon a knitting machine having parallel banks of needles, consisting in lifting the last loop cast of! from one needle, sec- 0nd in line from the end of one bank of active needles, carrying said loop across a loop upon the next adjacent needle at the end of that bank of needles, and casting it on to the next adjacent and theretoi'ore idle needle in the same bank, as a new stitch.

2. The herein described method of widening fabrics knitted on a Lamb type machine having two banks of needles comprising the steps of first, knitting the closing stitches, then knitting normally on the two banks of said machine alternately, then transferring the loop cast off from the needle next to the end loop-holding needle of one bank to the adjacent idle needle, then knitting once across, then transferring the loop cast off from the next to the last loop-holding needle at the end of the bank, opposite the first transfer to the first loopless needle of that bank, and then continuing such transfer at each half course until the desired width is attained always on the same bank of needles.
