UNITED STA ES steam PATENT OFFICE mrmon or'm'rrmq FABRIC Charles New-rm, N. r. Arm nian A ril :0, 1937, Serial No. 138,979 a r I a ms. (01. 06-9) This invention relates to a method of knitting a fleece fabric, double faced fabric or the like on a sinker top knitting machin Broadly, it is an object of this invention to knit a fleece or double faced fabric on a sinker top knitting machine, the back of which is composed of inlay threadstied to the loops of the base fabric by a secondary or binding thread known as the weft thread.

Another object pf this invention is to produce upon a sinker top knitting machine, a fleece or fleece or double faced fabric is to create and pro-- double faced fabric which duce at the same time producing a knitted fabric upon which there-is less possibility of damage to the cloth in the knitting process.

Another object of this method; of producing fleece or double faced fabrics is the ease and speed of production because of the multiplicity of. the feeds in the sinker top knitting machine. Another object of this method of producing a duce a larger and infinite variety of patterns due to the multiplicity of feedson such sinker top .knittingmachine.

Another object of method of producing a fleece or double faced fabric is that the needles and other parts of the sinker top knitting me.-

chine will have long life and use, and the ease of adjusting such sinker top knitting machine to produce such fabrics .will of time and moneys. I

Another object of this method of producing a fleece or double faced fabric on a sinker top knitting machine is that unusual heavy or nub permit a great saving yarns can easily be used as the backing thread,

thuscreating very heavy fabrics heretofore never knitted on a sinker top knitting machine.

These and other advantages, capabilities and features of the invention will appear from the subjoineddetailed description and more particularly pointed out in the claims appended hereto. In the accompanying drawings, which illus -tra te apractical embodiment of my invention,

I will now describe my method of producing a fleece or double faced fabric on a sinker top knitting machine by carrying through the knitting process necessary to produce one course of the fleece fabric shown in Fig. 10. For the purpose of illustration, but not in limitation of my invention, I will describe the operation of a unit ofsix successive" needles 24A to 24F, inclusive, as shown in Figs. 5, 6, and 7.

'Needles 24A and 24C are elevated selectively to receive inlay thread 3| from thread carrier 25 as shown in Fig. 5. The latches of said needles remain below knitting level L4 so that the previous knitting loops remain on the needle latch. At such point, cam 29, 'asshown in Fig. 4, actuates sinkers 2| so that inlay thread 3| lies .over sinker nose N2, as shown in Fig. 12, between points PI and P2 as shown in Fig. 11.

Needles

24B, 24D, 24E and 24F do not receive inlay thread 3| and rest at knitting level L4, as shown in Fig. 12, whereas

needles

24A and 240 are drawn down by stitch cam (not shown) to knitting level L2 as shown in Fig. 12.

Needles

24D and 24F are elevated selectively to receive inlay thread 32 from the thread carrier 25, as shown in Fig. 5. The latches of said needles remain below knitting level L4 so that the previous knitting loops remain on the needle latch. At such point, cam 29, as shown in Fig. 4, actuates sinkers 2|, so that inlay thread 32 lies over sinker nose N2 as shown in Fig. 12, and between points I PI and P2 as shown in Fig. 11.

Needles

24A, 24B, 24C and 24E do not receive inlay thread 32. Needles 24A and, 24C remain at knitting level-L2 and needles 24B and 24E rest at knitting level L4 (Fig. 12).

Needles

24D and 24F are drawn down to knitting level L2 by stitch cam (not shown).

A rising cam (not shown) elevates needles 24A to 24F, inclusive, to receive the weft thread 33 fed by thread carrier 21. The latches of said needles clear level Li, which is the top portion of the sinkers 2|, thus clearing the inlay threads 3| and 32 and leaving the previous knitting loops upon the shanks of 'the needles. All needles are then lowered to level L3 (Fig. 12) thereby causing the closing of the needle latches by the inlay threads 3| and 32, such needles then casting off said inlay threads 3| and 32, but retaining the' previous knitting loops upon said needles. At this point sinker cam 29 (Fig. 4) actuates sinkers 2| so that the knitting takes place upon sinker nose N2 at knitting level L2.

A rising cam (not shown) elevates needles 24A to 24F, inclusive, to receive the base thread 34 fed by thread carrier 28. The latches of said needles clear level Ll, which is the top portion of the sinkers 2| thus clearing the inlay threads 3| and 32 which are on the back shank of the needles and weft thread 33 and the previous knitting loops remain upon the front shanks of the needles. All the needles are then lowered below knitting level L4 (Fig. 12) thus casting off the weft thread 33, the inlay threads 3| and 32 and the previous knitting loop. At this point, sinker cam 30 actuates sinkers 2| so that the knitting takes place upon sinker nose N3 at knitting level L4, between point P2 and P3.

When weft thread 33 casts off inlay threads 3| and 32, such weft thread winds around the inlay threads asshown in Fig. 8. When the needles are elevated by the succeedingrising cam (not shown) such needles complete the winding around of said weft thread 33 about the inlay threads 3| and 32. When base thread 34 cas s oi! We t thread '33, inlay threads 3| and 32 and previous knitting loops, as shown in Fig. 9, said weft thread 33 becomes engaged with the loops of base thread 34 although not forming a knitting loop therewith and thus securing the inlay threads 3| and 32 to the base of the fabric.

I will now describe the sinker action in each successive step of the formation of the fabric. When needles 24A and 24C, take the inlay thread 3|, and are drawn down by stitch cam (not shown), to level L3, as shown in Fig. 12, sinker cam 29 withdraws sinker 2| so that the nose NI of said sinker clears inlay thread 3|, said inlay thread 3| being held on the nose N2 (Fig. 12) by the needles 24A and 24C. Similarly, needles 24D and 24F hold inlay thread 32 on the sinker nose N2.

When needles 24A to 24F, inclusive, are elevated to receive the weft thread 33, the needle latches clear level LI and the sinker cam 29 pushes the sinker 2| forward so that the inlay threads 3| and 32 are held against the shank of the needles by the throat formed between the nose N| and nose N2 of sinker 2|.

After needles 24A to 24F inclusive, receive the weft thread 33, cam 29 withdraws sinker 2|, and nose NI clears weft thread 33 so that said weft thread 33 casts off inlay threads 3| and 32 held on nose N2;

When needles 24A to 24F, inclusive, are raised to receive the base thread 34, cam 29 pushes sinker 2i forward so that inlay threads 3| and 32 upon nose N2 have been cast off by the weft thread 33 and are pushed over the tops of the needles so that such inlay threads 3| and 32 ride against the back of the shanks of the needles while the weft thread 33 rides against the front of the shanks of the needles. All three threads 3|, 32 and 33, remain upon nose N2 and the weft thread 33 is against the front shanks of the needles while the inlay threads 3| and 32 are against the back shanks of the needles.

After needles 24A to 24F inclusive, receive the base thread 34, cam 30 withdraws sinkers 2| so that the nose N2 clears base thread 34 and permits the previous weft thread and inlay threads to drop to knitting level L4 at which point base thread 34 casts off the weft thread 33 and inlay threads 3| and 32.

The previous described consecutive knitting steps can readily be seen in the enlarged needle units of Figs. 6, 7, 8, and 9, corresponding to the knitting of inlay threads 3| and 32, weft thread 33 and base thread 34, respectively.

By a similar method as above described, by

. utilizing multinosed sinkers, as shown in Fig. 13,

last weft thread becomes engaged with the loops of the base thread.

Fig. 14 shows such a thread 35 is interlaced by in turn is interlaced by a weft thread 31, said weft thread 31 becoming engaged with the loops of fabric in which an inlay a weft thread 36, which.

base thread 38 comprising the base of the fabric. I

It will be obvious to those skilled in the art that the invention may'be embodied in the various types of sinker top knitting machines and that other changes may be made therein. I therefore do not limit myself to what is shown in the drawings and described in the specification but only indicated in the appended claims.

The method of producing the above described fabric upon a sinker top knitting machine can utilize spring needles as well as latch needles. I therefore do not limit myself to the type of latch needle described in the specification.

I do not limit myself to the above'described combination of the number and texture of inlay threads, weft threads and base threads. In other words, one or more inlay threads, one or more weft threads and one or more base threads may be knitted in any combination to produce a wide variety of knitted fabrics.

It is also within the scope of my invention to produce a fabric upon a sinker top knitting machine which has sinkers containing 2, 3 or more levels to the corresponding 2, 3 or more knitting planes.

I claim:

1. A method of knitting a fabric upon a sinker top knitting machine with sinkers having two steps characterized by the following sequence of operations, namely, elevating needles so that the latches of said needles are below the upper step of said sinker, the already formed stitch loops holding said latches against the shanks of the needles, feeding an inlay thread to the hooks of said needles and drawing said needles down so that the hooks are below said step while said inlay thread rests within the throat of said step, elevating needles so that the latches clear said inlay thread, feeding a weft thread to the hooks of said needles and drawing said needles down so that said hooks are below the upper sinker step thus casting off said inlay thread but not the already formed stitch loops while said weft thread rests within the throat of said step, elevating needles so that the latches clear said weft thread, feeding a knitting thread to the hooks of said needles, withdrawing said sinkers whereby the already formed stitch loops drop to the lower sinker step, drawing said needles down to castofi said weft thread and the already formed stitch loop.

2. A method of knitting a fabric upon a sinker top knitting machine according to claim 1 wherein more than one inlay thread is fed to the hooks of the needles at successive feed points to be cast off by the Weft thread.

3. A method of knitting a fabric upon a sinker top knitting machine with sinkers having three steps characterized by the following sequence of operations, namely, elevating needles so that the latches of said needles are below the upper step of said sinker, the already formed stitch loops holding said latches against the shanks of the needles, feeding an inlay thread to the hooks of said needles and drawing said needles down so that the hooks are below said step while said inlay thread rests withinthe throat of said step, elevating needles so that the latches clear said inlay thread, feeding a weft thread to the hooks of said needles and drawing said needles down so that said hooks are below the upper sinker step thus casting ofi said inlay thread but not the already formed stitch loops while said weft thread rests within the throat -of said step, elevating needles so' that latches clear said weft thread, feeding a second weft thread to the hooks of said needles, withdrawing said sinkers whereby the already formed stitch loops drop to the intermediate sinker step, drawing said needles down so that said hooks are below said intermediate sinker step thus casting off said first mentioned weft thread but not the already formed stitch loops within the throat of said intermediate step, elevating needles so that the latches clear said second mentioned weft thread, feeding a knitting thread to the hooks of said needles, withdrawing said sinkers whereby the already formed stitch loops drop to the lowest sinker step, drawing said needles down to cast off said second mentioned weft thread and the already formed stitch loop.
