Application filed September 8, 1914. Serial No. 860,642.

To all whom it may concern.-

Be it known that I, FRANZ CEcKA, a citizen of the German Empire, residing at Chemnitz, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Knitted Goods and the Method of Making the Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference'being had to the accompanying drawing, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in knitted goods and the method of making the same. The object of the improvements is to provide a method of making knitted goods in which loops are widened over two or more needles, and in which no holes are produced in the fabric by the widening of the loops.

In making knitted goods the loops are or-. dinarily widened by shifting a number of loops laterally a distance corresponding to the pitch of the needles, whereby the needle located at the beginning of the widened portion becomes disengaged, and a hole is produced in the fabric which however is not objectionable, and can even be removed by hanging on the disengaged needle the loop of the previous row of loops. Heretofore it was not possible to widen a number of adjacent loops over two or more needles for the reason that at some part a hole was produced which extends over two loops, so that when continuing the workit was impossible to take up the thread for forming further loops. formed.

For certain sorts of goods such loops may be satisfactory. But in smooth fabrics they are objectionable and must be avoided.

However, in some cases the desired form is not obtained by widening over single needles and it is desirable to widen two or more loops.

The object of the improvements is to provide a method by means of which the loops can be widened over two or more needles without producing ladders. "With this object in view my invention consists in interrupting the series of widened loops in such a way that before the last widening needle loops are omitted-in widening.

At such places so called ladders were a For example, if it is desired to widen over two or three needles, a needle must be omitted before the first row, and thereafter a further widening needle must be added.

For the purpose of explaining the invention an example of a fabric made by my improved method has been shown in a diagrammatical way in the accompanying drawing. I

As appears from the example shown in the drawing the formation of ladders is avoided, because no hole is made which extends over two needles, but at two places which are separated by a loop holes of the breadth of one loop each are formed. 1 1

In the example shown in the drawing widening is to be performed on the part of the fabric which is at the right ofthe line AB, which part contains the loops 1, 2, 3, 4, 5, '6, 7. The widening apparatus is made in such a way, that the Widening needle a so acts on the loop 1, that in the position of the loop 2 there is no widening needle, and that in the position of the third and following loops before all the further loops to be widened widening needles 6, c,

d, e, f are located. If after completing the series I the loops are widened over two needles, loop 1 gets into the position of loop 3, loop 3 into the position of loop 5, and each of the following loops is shifted to the right a distance corresponding to the double pitch of the needles, as appears from row II.

As loop 2 has .not been widened the hole which would otherwise be produced at the left of widened loop 1 and extend over two needles is reduced to a hole which extends only over one needle, as is shown in row II at 1, a second hole being produced at the right of the widened loop 1, as is shown in row II at 4. As appears from the diagram, when continuing the knitting operation at the height of each needle, loops are formed for the further loops to be produced in row III. In row IV the widening operation has begun at loop 3, so that the holes are passed over to the right according to the increase in the breadth of the fabric, as is shown in row IV, at 3 aud t The holes which are thus produced can be closed if desired by known methods, for

example by pulling out a loop from the previous row and hanging the same on the corresponding needle of. the succeeding row.

An important feature of my invention consists in that the holes which are produced by thewidening operation are closed or reduced to the distance of two consecutive needles by the loops which ave not been widened. 4 v

I claim herein as my invention:

1. The method of producing on a knitting machine, a knitted fabric having at least one v widened portion which comprises regularly knitting at least one row of loops, widening atfleast one succeeding row of loops by transferring a group of loops for at least two needle divisions; and reducing the gap produced at the commencement of the said transference to the-width of one needle division by excluding from said transference at least the second loop within said group whereby the loops of the succeeding row are a I locked against raveling.
