BRAID-KNI TTING- MACHINE.

Application filed June 20,

'To' a'ZZ whom it may oo'vwern:

Be it known than, JOHN A, Lrsr, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Braid-Knitting hil'achines, of which the following is a specification.

My invention relates to certain improvements in knitting machines for knitting and fulling braids.

One object of my iiivention' is to design the mechanism so that the failed portion of the braid will not be flattened as it passes through the machine, but will retain its original shape. 7

A further object of the invention is to design the nie'cl'i'anism so that one, or more stitches can be formed at th'e; loops" of the braid, giving the rounded effect shown in the drawings.

In the accompanying drawings:

Fig. 1 is a transverse sectional view of my improved machine for knitting braid;

Fig. 2 is a plan view of a portion of the machine;

Fig. 3 is a perspective View;

Fig. 4 is a detached perspective view of the braid guide;

Fig. 5 is a face view of the braid;

Fig. 6 is a side view of the same;

Fig. 7 is a perspective view of the braid;

Fig. 8 is a view of the back of the braid;

Figs. 9 and 10 are views illustrating different forms of braid; and

Fig. 11 is a view of a modification of the braid guide.

Referring to Figs. 5, 6, 7 and 8, which illustrate the fashioned, fulled braid, 1 is a strip of woven ribbon. 2, 2 are the knitted side members, which are knitted onto the edge of the ribbon at intervals. The spaces between the points 3 of attachment are fulled so as to form tubular, raised portions 4, which give the unique effect shown in the drawings.

Referring to Figs. 1, 2 and 3, which illustrate the machine for making the braid, 5 designates the needle bar of a knitting machine, having grooves 6 for the latch needles 7. These latch needles are actuated in the manner common to knitting machines.

8 designates a longitudinal bar carrying the ribbon guide 9. 1O designates the plate bar, which carries guides 11 for the warp threads 2. 13 designates the loopers that 192? Serial No. 646,552.

are mounted on bars 14. These loopers have eyes through which the warp threads 2* pass to the needles, as clearly shown in Fig. 1.

The ribbon guide plate 9 is preferably made as shown in Fig. 4, andhas a Hat portion' 15 in wl'ii'ch is a transverse slot 16. The guide plate back of the slot is reduced in width to all ow' for" the free movement of the needles. @n the reduced portion is a cylindrical guide 17 tl'irough which the ribbon passes to the slot 16. The cylindrical guide 17 is less in width than the ribbon, but the slot is of a width to allow the ribbon to pass therethr-ou'gh in a flat condition. By making the guide 17 narrow, the needles are allowed to form one or' more stitches under the looped portions of the ribbon',as shown in Fig. 9, giving the rounded effect shown in the drawings. On the back ofth'e guide plate is a bar 18, which is hooked to encircle a screw 19 that is secured to a plate 20, which is attached to the bar 8.

2.1 designates abar that is located at the top of the needle bar and in close proximity to the needles for forming the looped,

raised portion 4 of the ribbon. This bar is carried by suitable support.

The ribbon 1 is fed through the round guide 17 and then through the slot 16 in the guide plate 9 and over the bar 21. The warp threads 2 are fed through the guides 11 and the threads 2 are carried by the loopers 13. These loopers move back of the needles to carry the thread beyond the needles, after which they are shogged to wrap the thread around the needles. They are then moved forward so that the hooks of the needles will draw the threads down to form stitches on each side of the ribbon. One set of stitches passes through the edges of the ribbon and under the raised portion, while the other set of stitches is formed beyond the edge of the ribbon, as illustrated in Fig. 5. The bases of the looped portions of the ribbon are spaced apart so that the loops will retain their shape.

In Figs. 5, 6, 7 and 8, the loops are illustrated at equal distances apart. In Fig. 9, the loops are illustrated as arranged in groups of three. It will be understood that the loops may be arranged in many difierent ways to produce various effects.

By contracting the ribbon at the knitting point, one or more stitches can be formed under the loop at each side thereof, which produces the fullness desired.

In Fig. 10, three stitches are formed under each loop. In Fig. 11, a modification. of the guide is shown, in which two guide arms 17 project from the narrow portion of the plate 9, contracting the ribbon to allow for the passage of the needles.

It will be understood that while I have shown a single guide and a single set of needles, the guide and needles are duplicated throughout the length. of the machine, by means of which several braids are formed simultaneously.

I claim:

1. The combination in a machine for forming looped braid, of needles; and a guide having a flat guiding portion for a ribbon and having a contracted portion less in width than the flat guiding portion, said contracted portion being on a line with the needles.

2. The combination in a braid knitting machine, of a needle bar; thread guides; and a ribbon guide extending between two sets of needles, the guide having a slot therein for a ribbon to pass therethrough in a flat condition and having a portion on a line with the needles less in width than the slot.

3. The combination in a braid knitting machine, of a needle bar; two sets of needles; guides for the threads forming the knitted stitches; a ribbon guide having a flat portion extending between the two sets of needles, said flat portion being slotted for the passage of the ribbon; and a cylindrical guide narrower the the slot and the space between the needles through which the ribbon passes prior to its having the knitted loops secured thereto.

4. A ribbon guide plate having a transverse slot of a width to allow a ribbon to pass therethrough in a flat condition, the guide plate back of the slot being narrow to allow for the movement of knitting needles;

and means, on the narrow portion of the plate, for contracting the ribbon to allow it to clear the needles.

5. A. ribbon guide for a braid-knitting machine, the same consisting of a plate slotted for the passage of a ribbon in a flat condition, the guide plate back of the slot being narrow to allow for the movement of the knitting needles; a cylindrical guide on the narrow portion of the plate for contracting the ribbon to allow it to clear the needles;

and means by which the guide is attached. to a knitting machine.
