To all whom it may concern;

Be it known that I, ROBERT W. Scorr, a citizen of the United States, residing at Leeds Point, Atlantic county, New Jersey, have invented certain Improvements in Knitted Fabrics and in Modes of Making Same, of which the follow is a specification.

M invention re ates tothat class of knitted abrics which are ribbed throughout but in which there are a eater number of wales in one portion of the abric than in another.

The object of my invention is to produce a machine knit fabric of this character, in which the c e is from ribbedweb having the lesser num r of wales to ribbed web having the greater number of wales, and in which, furthermore, the change can be readily efiected by manipulation of the needles and without stopping the machine or requiring the intervention of an attendant, the invention being therefore especially adapted for use in the manufacture of hosiery upon automatic knitting machines.

- In the accompanying drawings, Figures 1, 2, 3 and 4, are views of fabrics made "in accordance with m invention which are ribbed the bout, an in which the change is. offee from web hav' the lesser number of wales to web having th wales; 5 and 6, are views illustrating the a ment ofneedles and the-course of am which may be adopted in roduc' lie of the character shown in 1; lgs. 7 and 8, are views illustrating the arrangement of needles and the. course of the knitting Kern which may be adopted in produenl g a tie of the character shown in ig, 2; 1 9 and 10, are views illustrating the arrangement of needles and the course of the knitting Kern which may be adopted in producing a tie of the character shown in ig. 3;F1gs. 11 and 12, are views illustrating the arr ment of needles and the course of 1 the knitt ng gain which may be adopted in roduc: a ric of the character shown in.

sent rib stitch wales which also extend e greater number of throughout both webs 0 represent com osite wales having plain stitches in one we and rib stitches in the other, d represent introduced plain stitch wales and 6 re resent introduced rib stitch wales. P ain stitch wales may be described as those having all the point of change of the webs. I T

e fabric/shown in Fig. 1, is one which is ribbed throughout but in which there is a thirty-three-and-one-third (33) per cent.

doubling, that is to say, one web has thirty three-and-one-third (3%) per cent. more wales than the other. This {this can be produced upon a machine of the character shown in F1 sent the cylinder needles which are always in action, and .w a cylinder needle which is out of action in knitting the web having the lesser number of'wales, representing dial needles which are always in action and y dial needles which are in action during the knittin of the web havin the lesser number of wafes but which trans er their stitches to the cylinder needles w in changing from the web having the lesser number of wales to that having the greater number of wales; Dial needles y are out of action'during the knitti of the web having the lesser number of wlifes but are put into action so as to produce the extra wales ein starting the web 5 and 6, in which 2:, a: reprehaving the greater number of Wales, these dial needles y being sho ged'o, their introduction so as to carry t e initi loxzips y of the introduced wales 6 across the a JOlJI Hg standing wales, and thus preventt'h'c formation of eyelet holes.

In the fabric shown in Fig. 2, there is a fifty (50) per cent. doubling, or fift (50,) per cent. more wales in one. portion 0 the web than in. the other. This fabric can be pro-. duced u n a machine of the character shown in igs; 7 and'S in which 2: and 'y represent, respectively, the cylinder and dial needles Wl'llCll are always in action, 2: and 3;" representing respectlvely cylinder and dial needles which are out of action in knitting the web havi the lesser number of wales but which are rought into action so as to was having being shogged across produce the additional wales d and e in changing from one web to another, the dial nee-- dle being sho ged so as to cross its stitch with that ro uced upon the introduced cylinder nee e as shown at :r and y in Fig.2.

In this fabric there is no composite Wale produced by shifting a stitch from' a dial needle to a cylinder needle, or vice versa.

Fig. ,3, illustrates a fabric made in accordance with m invention in which the change is from a we having a one-and-one-rib to a a tWo-and-one rib, this change being effected by introducing extra c 'linder wales d, the arrangement of the nee es in a I dial needle y alongside of each cylinder and dial needle employed in knitting the web having the lesser number of wales, such farrangcment of needles bei shown in Figs. 11 and 12, and the initial sti t hes at and y of the introduced wales being crossed in the manner'before described in connection with the fabric shown in Fig. 2.

' In Figs. 5, 7, 9,-and 11, the dotted lines represent/the succession'of needles to which the'knitting yarn isfed' in knitting the webs having the lesser number of wales, and in Figs. 6, 8, l0, and 12, the dotted lines represent the succession of needles to which the knitting yarn is fedin knitting the webs having the greater number of wales.

In. ,carryin out my invention various forms of mac e may be employed, but in- Figs. 13 and .14, I have shown sufficient of the elements of one form of .nachine which has provenefl'ective ii ractice to impart a proper understanding o the method of manipulating the necdlesto effect the transfer of stitches from one to another. In these viewslfij'epresonts part of a needle cylinder and'll part of a dial on the insideof the cylinder; The dial needles y, y aie' carried by the lower ends of jacks 1'2 iivotally mounted upon a ring 13, and raving their iipper ends acted upon. by cams carried by a cam plate 14, this plate having two setsof cams,- one for. iii-ling upon the jacks so as to cause operation of. the dial needles forfordinaryi knitting, and another set forcausing' abhor-' m'al projection of the dial noodles, as shown in Fig. 13, so as to carry them outwardly beyond the cylinder needles; This has the effect of drawing or stretching the web so as to dispose rib stitches over the cylinder as different yarn fee stitches, as also shown in said figure.

The projectionof the dial needles may be such as either to bring the stitches upon them, or recedently formed stitches, above the cylin er needles which are to engage the}.

same. je'ctedso as to enter the stitches upon the dial needles, either of the needles maybe When the 'cylinderneedlesare' pro- 7 moved laterally to the extent necessary to I cause engagement of the cylinder needles with the dial stitches, and can then be withdrawn so stitches onto the cylinder needles. I

the dial needles as to cast When.

the cylinder needles engage stitches other than those upon the dial needles, the lateral.

movement referred to will not be necessag as the slackening'of the rib stitch on .t

withdrawal of the dial needle will cause it to engage with the cylinder needle which has previously entered the same. In changing stitches from cylinder needles to dial needles S8.ld cylinderneedles will be provided with projections or butts, such for instance, as

shown at w (Fig. 15) for stretching the cylinder stitches and permitting the dial needle's to enter and engage the same. 1

, My. improved fabric can be knitted without arresting the operation of the. machine and by the use of a continuous thread, it being understood that the knitting cams and the transfer camsaredispo'sed at points so remote from each other that the kmttingjoperation can be going forward u ncertalnyof the needles of the machine'whi e stitches are being transferredfrom and to-other needles of the machine at a point more or less remote from the knitting point.

My invention in its broader sense is not limited to a web; composed of ar-s' le continuousyarn, since it is manifest t t different yarns may be emplgyed in either webwhen it is desired to pr uce a mixed or striped effect therein by the of yarnsof different colors su plied to the needles .by

(id, but even in that case there will be courses of stitchesknitted with a continuous yarn common to both webs, although the term continuous does not necessaril imply unbroken -continuity, as yarns of different color or character ma be used in difl'erent portions of the web so ong as the meeting ends of said arns overlap or provide for a continuous eed of yarn to needles of one and the same machine. manifest also that the transferied stitches and the introduced stitches may be in any desired courses of the fabric, that is to say, after the straight transfer of the stitches of some of thewalcs, an desired number of courses may be knitte before further wales are started by introducing stitches and the reverseof this proposition is equally true.

Havingthus described my' invention, I

It is' i itial stitches senses claim and desire toisecurebyLetteI-s Patent:--

'1. A knitted fabric two ribbed webs, one with a greater num 45 than the other, the introduced wales inthe latter web havinfi theirinitial stitches drawn acrom wales in t e other face of the web.
