mrrrrine-Mecnmn To all whom it may concern I Be it known that I, HERMAN GoLnNER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, county and State of NewiYork, have invented a new and Improved Knitting Machine, 'of which the following is a full, clear, and exact description.

This invention relates to improvements in knitting machines such as adapt them to the making of knitted fabric while laying a'loose or extra yarn in place during the knitting operation.

Another object of the invention is to cause the production of a non-stretchable piece of fabric through the placing in the fabric of an-extra yarn. 7

A still further object of the invention 'is to place an extra yarn inthe knitted piece of fabric so as to extend throughout the fabric, or to occupy sections thereof, whereby the fabric maybe caused to assume'diiferent forms'or designs.

In carrying outthe objects of the inven- 'tion, any kind of a knitting machine may be used, as for instance what is known as a horizontal knitting machine, As the yarn or thread being knitted is moved back and forth, in my. improved knitting machine a special part of themechanism associated therewith is designed to lay loosely inplace an extra yarn or thread in front ofthe knitting so that as the knitting progresses the laid in yarn will be inclosed. This extra yarn or thread acts as a filler and as means for preventing stretching of the knitted goods. The special mechanism is connected with or. built into the machine .in such a" manner as to always cause the laid in yarn to be placed in position in front of the'knitting, whereby the knitting always inclose's the extra yarn. u g A practical embodiment of themventlon is represented in the accompanymg drawings forming a part of this specificationw inwhich similar characters of reference 1nd1-' cate corresponding parts in all the views- 1 Figure 1 is a transverse section through a horizontal knitting machine embodying my improvement, certain parts being broken away; Fig. 2 is a section through Fig. 1 approximately on the line 22;

thread 3 operates. It will be understood,

however, that lmitting machines embodying substantially the usual construction may be built along special lines to embody my -improved extrathread mechanism for producing the-non-strething fabric in any desired or preferred form. The machine ,1 is provided with an arm 4 adapted to be moved back and forth so as to properly operate the thread I guide 5. The operation of the needles 2, guide 5, and the other parts of the knitting machine being old and forming.

novpart of theinvention, will not be further descr bed except that in this form of the machineythe member 5 is moved back and forth, and upon each movement the needles knit one row of loops. The special mec'ha-.

nismoembodying the invention is connected with arm-4 excepting a stop arm 6 arranged at each end of the machine adapted to engage the stops 7 and 8, respectively, on that portion of the mechanism mounted on arm 4.- The special mechanism is provided with a frame 9, bolted, riveted, or otherwise secured to arm 4 so that the same may be. easily applied and removed whenever desired. Frame 9 is provided with a'pair of

end members

10 and 11, as shown in Fig. 4,

. which have connected therewith a front bar 12 formed withnotches 13 and 14 in which the end of spring 15 is adapted to snap upon each extreme movement of arm 4 and-the attachment carried thereby. -As shown, in

Figs. 2 and 4 bar 12 is notched from the end members 16 and 11, pivotally mounted clamping arms 16 and 17 are provided whichare formed with hooked portions 18 and 19 adapted to hook beneath end members and 11. The friction of members 16 and 17 against bar 12 is usually suflicicnt for holding the members 16 and 17 in any position in which they are placed so that they will remain in their hooked position. until positively moved therefrom. However, it is evident that any desired means may be sed for holding members 16 and 17 in their locked position without departing from the spirit of the invention. Bar, 12 is provided with a longitudinal slot 20 through which extends a block 21 riveted or'otherwise rigidly secured to spring 15, and also to a sliding plate 22. Spring overlaps the edges of slot and acts as a retainer for holding plate 22in place, as well as a locking means whenever the end thereof snaps into either of the notches 13 and 14. Plate 22 is provided with the stops 7 and 8, heretofore described, which are designed to engage the arms 6 of the opposite ends of the 'prc des'the yarn to be knit, and the other follows said yarn. It will also be observed that the extra or laid in yarn 25 is laid in ahead of the yarn that is being knit so that asthe needles knit the same cause the last row of knit material to encircle the laid in yarn. As the machine moves back and forth in the usual manner for causing the proper operation of the needles, and also'the proper feeding of the yarn 29 for knitting the fabric in the usual manner, the plate 22 and fin er 23 precede the member 5 until stop 7 stri es against arm 6, whereupon plate 22 will stop, but arm 4 and the various members carried thereby will continue to move to the end of the stroke of the machine. This will cause the arm-5 to move past finger 23, and as the machine begins its return movement finger 23 will precede the feeding member 5 and arm 4 until stop 8 strikes against arm 6' at the opposite end of the machine. When plate 22 is stopped 'by' arm 6, as shown in Fig. 2, members 9 and 12 (Fig. 4) will continue to move with their associated parts so that spring 15 will be forced out of notch 14 and will be permitted to snap into notch 13 upon the completion of the stroke of the machine. The end of spring 15 will remain in notch 13 until forced therefrom by 1,21e,eea

arm 6 at the opposite end of the machine. By this means the dispensing member 24:

which is formed at the end of finger 23 is caused to move back and forth over the knit fabric, and is held'out of contact therewith so that the knit fabric will not be injured in any Way even though the same is composed of very fine material.

Various designs or figures may be made with my improved knitting machine by merely shifting some of the needles in the well known manner. In the fabric shown in Fig. 2 the same is an ordinary fabric where all the needles are used and the extra yarn is merely laid in, each row of stitches. In case it is desired to make stripes extending longitudinally of the fabric 26 some of the needles 2 could be thrown out of operation whereby two or more adjacent rows of stitching on one side would be omitted and thus disclose only the laid in yarn 3. if the laid in yarn 3 was of'a difierent color from the yarn being knit the stripes would of course be of a different color from. the remaining part of the fabric. The needles could be thrown again into operation at any time whereby various forms and configurations could be produced. This method of changing the appearance of the fabric by dropping certain of the needles is well known in the art and need not be further described.

The extra thread mechanism has been shown in connection with a horizontally reciprocating knitting machine which has a thread guiding member adapted to move back and forth, but it will be evident that the special extra thread mechanism could be built in connection with a cylindrical knitting machine and the yarn 3 caused to be laid in proper place ahead of the corresponding guide 5; It is to be observed that the special mechanism here illustrated shows means for laying in the yarn 3 ahead of guide 5 which isthe preferable construction, but if desired the plate 22 .and associated parts could be so arranged as to lay in the thread in back of the guide 5 without departing from the spirit of the invention.

What I claim is- 1. The combination with a knitting machine, of a thread guide carriage, a support mounted thereon, an auxiliary guide mounted on said support and adapted for laying a loose yarn in the knit fabric and brushes mounted on said support to brush the edge of the knitted fabric in a direction parallel to said loose yarn preceding and following the laymg in of said loose yarn.

2. The combination with a knitting machlne, of a thread guide carriage, a support mounted thereon, a removable track bar carried by said support, means for removably securing the track bar to said support, a reciprocating auxiliary guide slidable on said track bar and adapted to lay a loose yarn in a the .knit fabric substantially as described and brushes depending from each end of said track bar support to brush the upper edge of the knitted fabric in a direction parallel to said loose yarn.

3. The combination with a knitting machine, of a thread guide carriage, a support mounted thereon, a removable track bar carried by said. support, means for removably securing thetrack bar to said support, a reciprocating auxiliary guide slidable on said track bar and adapted to lay a loose yarn in the knit fabric and vertically disposed brushes mounted on said support and arranged to precede and follow "said auxiliary guide and brush the edge of the knitted fabric substantially as described.

4. The combination with a knitting machine, of a thread guide carriage, a support thereon, a removable track bar on said support, an auxiliary guide member mounted to reciprocate on said track bar and adapted to lay a loose yarn in the knit fabric and a spring latch finger mounted on said auxiliary guide member and adapted to cooperate with notches in said track bar to hold said auxiliary guide at either end of the track bar substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
