' WALTER GRANOY BY ATTQRN aYs Sept. 12, 1950 w. GRANOV KNITTING MACHINE 5 Sheets-Sheet 5 INVEN TOR. WALT ED. QRANOV Filed April 9, 1949 ATT ORN EYS Patented Sept. 12, 1950 This invention relates to improvements in undergo a, transferring knitting machines and is concerned I more especially with knitting machines of the V-bed type having inclined needle beds.

In machines of the type indicated two up; wardly inclined needle beds are arranged sub;

stantially perpendicularly to each other and the knitting operation is performed in the longi" tudinally extending space between the twoneedle" beds. Needles, and needle jacks or pushers are;

slidable in grooves orchannels formed in each bed and the motion of the needles and needle jacks are controlled through the agency" of a system of cam blocks mounted on cam plates" forming a part of the carriage reciprocating over" the needle beds.

'A primary object of the invention is to provide a, novel construction for selectively controlling"- the motion of predetermined needles in the needle beds in such a manner as toincrease or diminish, as desired, the number of stitches in successiverows or courses'of a knitted article without requiring interruption of the knitting": operation or resetting of the machine once the; initial adjustments have been made. In carry ing out this object of the invention I employ" stitch-transferring needles substantially of the type disclosed in Patent No. 2,326,694 issuedto Julius Sirmay and dated August 10, 1943. These needles are of the sliding, latch type and are pro vided with a laterally extending loop-opening,

transfer clip. While the identified patent illus trates a transfer needle having a transfer clip" extending on the right side of the needle body, I find it necessary'to employ two types of such transfer needles, one having a transfer-clip on the right side of the needle body and the'other: having a transfer clip. on theleitside of theneedle body, the needles being arranged-sym--' metrically with respect to the central axis of symmetry of the knitted article and the wan verse center line of the needle beds and the arrangement of the transfer clips on both sides 1 of the transverse center line of the machine being determined by the direction in which it is desired to diminish the stitches, as will appear more fully hereinafter.

Another object "of the invention i's thepr'ovision of a novel construction of'the character I iirows at different portions of the garment;

indicated including a novel arrangement "of cam" blocks and a dual jack'control of eachtransfer clip needle so that for a single traversing move ment of the'carriage over the needle bedtit'will operation, subsequent to: their knitting operation, wherein their loops'will be temporarily. transferred ,toian adjacent needle; ofnthe rear -b edrth'e diminution of one or more stitches-,. in. thessucceeding ;row of the articles beingaccomplished upon the return stroke ot;v the carriage by the transfer of; the previouslytransferred .stitchiornstitches-irom the needle of the r arrbed .toaarespective needle ofthe;

the selected. needles in a given-direction of travel": of the-carriage and to reverse the sequence during the return =strokeof the carriage. 1 E

A- further object I fwthe -inventionis the pro-: vision ofa knitting machine of the'character indicated wherein the sequential operations-of the machine -may-:beqcarried 2 out rapidly,

rear bed and thence back to a needle of the front bed adjacent the original transfer needle in order to diminish successive rows of "the knitted article by one stitch. Figs. '7, -8,..9, 10

and 11 are taken on lines 1-1, 8-8, 9-9, Iii-i0 and ll-ll of Fig. 3 while Figs; 12, i3 and 14 respectively of Fig. 6.

Referring now to the drawings in greater detail,

movement of certain of the needles to transfer position in a continuous, automatic operation without any interruption of the knitting operation and without any interference with the normal reciprocatory movement of the carriage.

In the drawings the needles '22 and 22a are illustrated as being of the single latch type having transfer clips 25 and the movement of each needle into operative engagement; with selected camblocKson Caiir platesi 23 and Z lis controlled by preadjusting one or both jacks or pusher . elements 26 and 21 in a manner to be more fully described. For purposes of convenience and clarity; elements 25 will be designated the inner jacks or pushers and elements 2'! will be designated the outer jacks or pushers corresponding to their disposition within the needle bed. are taken on lines l2--l2, l3-l3 and I l-I4;

front and rear beds are upwardly inclined and substantially perpendiculafto each other. Il'ach of said needle beds is provided with a. plurality. of grooves or channels which slidably retain knit ing needles having stitch-transferringmeans or,

so-called transfer clips which are operative in. the

position of extreme forward projection of the:

needle, hereinafter designated the transfer posi# tion.

An important feature of the invention resides in the provision'otineans including dual jacks or pusher elementsfor each transfer clip needle and a novel arrangement of cooperating cam blocks mount'ed'on the underface of the reciprocating carriage of the machine so that certain of the needles may be preselected for movement to transfer position and the transfernormally occurs duringthe reciprocation of: the

ring of one or more stitches maybeaccomplished simultaneously with the knitting operation which carriage. The arrangement'ofthe presen'tinvention establishes an autoniatic'seciuence of operations whereby all of the needles (including those needles preselected for movement to trans feet position) executea nanngdeeranon, the" knitting operation; a subsequent nt'eh n'ansfn ring operation, as will "be mereruu ues n ea hereinafter.

' preselected needles executing; mana ements" It has been found desirable to employs'titchtransferring needles having transfer clips 'of the type described in theaforementioned PaI tehtNo. 2,326,694 to Julius Sir'may wherein the transfer clips are illu strated extendinglaterally ltne right side of thenee'dle body. However, since the];

diminution of the num r of stitches in successive rows of a fashioned knittedarticle will generally be carried out symmetrically on both sidesfo'f the article, as shown in'Fig. l, it'i s'n'ecessary to employ two types of transfer needles, one having a. transfer clip on the right side of'the'needle body which has been designated 22 and the other type,

Each cam. plate carries on its underfa'ce a plu-' rality of cam blocks arranged in such a manner as to'control the movement of 'allth needles to their knitting position" and: to selectively control the" Needles 22 and 22a, inner jacks 25 and outer jacks 21 are provided with projections or lugs 22b, 26a and 27a. respectively-l andare actuated within their respective channels by tha-en gageme t of 1 said lugs against respective controlling camscan ried by cam plates 23 .andi l inrorde tOePQlflform;
