T o. all whom it may concern:

Be it known that l, Flinn citizen of the United States, resid-in vwege, in the county oOswego and?) nrrn, a

tate of NewYork, have invented certain new and 'useful im rovements in Knitting-lli/Iachines, of which the following is a specification, ref-' erencc being had therein to the accompanyf ing drawing.

My invention relates 'to an improved knit'- 'ting machineand i declare that the following is a full, clear, concise and exact descrip- .tion thereoi` suiiicient to enable one skilled in the art to make and use the same, .reference being had to the accompanying drawin s in which like to ike parts throughout 'The invention is applicable to that class of knitting machines known 20- as springneedl connectlon with a machines and is shown in that class and I,

Referring to the ofthe base-plate, B represents 'the cylinder, with needles ajb, c, d, represented in ONE-THIRD To DAVID M. rasante' drawings, A shows part by 'curved lines' thus' lettered showing the are` well known in shownfin Fig.- 1 passingv to the right) the needles, when they come to' one feed, have on their shanksthe stitches supplied at the former feed and its cooperating parts. feeds and connected parts are not shown as theyv are well-knownv in 'the art and .their- ,form and position will be understood.

The-- the second of the two feeds which are mentioned the'I needles receive additional loops and it is assumed that certain' of the. loops there received are to be transferred from one needle to another, to cause fabric. It is very important that these loops len th to permit this or reaking of thread an irre ular o r oth.

short stitches between the groups of long ones and that no blade is necessary between the said groups of large blades. The terms applied to wheelE are those of convenience, since it is not strictly a landing wheel, but lifts the irregularly divided yarn a distance which is necessary in this peculiar construction. As indicated, these wheels are to be mounted on-the fixed structure by the familiar presser stand or other suitable means. Thel revolution of the cylinder then brings the needles to the devices provided for tran-sferring-the stitch or loop, the stitches being arranged, in this particular construction, as two long and two short, alternating pairs. These devices comprise a transfer wheel, F, a stitch controller F and an .alining presser or needle controller G cooperating therewith.

The transfer wheel' F is mounted on a standard, as other parts are, and turns freely. by engagement of the needles therewith. In the form here illustrated it comprises a toothed disk, F. The disk F has the teeth spaced to receive two needles between them inthe natural work of the machine and each slotted at f to receive two needles the first of which is forced to the left, the second being forced somewhat to the right, making the first standing directly back of the second needle entering the slot. This construction is to be modied according to the Work to be done.` The edges of the slot diverge at the end'as clearly shown, one to allow free accessI of the first of the ltwo needles to reach the slot, and the other to force the second needle behind the first, in the slot. The tips of the teeth are suitably and slightly beveled as at fa toallow easy passage of the cloth or stitches down on the needles. The stitch controller .F/ is a disk of slightly less diameter than the disk F. It might be made integral though I show it as a separate piece. On its periphery it has downwardly projecting pins f which register ,exactlyy with the ti s of the teeth and adjacent the upper face o each, but in this instance do not quite touch the surface of the teeth because of the annular shoulder or rim f to limit the contact of the ins with the teeth When the parts, are assembled, the purpose being to provide guards to confine thev stitches within the space occupied by the needles. *v

The loop which is on the needle first to enter the slotlisto be sli ped over the head of the second needle. T 1s is done byressing downthe cloth or web after it has been alllowed by the natural pull or strain to rise far enough for clearance. But it has been found that the loop sometimes slips to one side of To prevent that I provide side to the space Whilel have shown a construction having these pins it is obvious that other mechanical forms in eect providing a chamber for .the

has been customary lto sesam' loo might be given to the deviceto accomplis the same result of controlling the stitches vand still be within the scope of the invention. For instance, p the cap plate might bechambered to present tooth edges like the ins: to provide means to confine theloop aterally as in Fig.v 9 Where is one side of such a chamber, the disk F orming the top and back walls. y

G is the curved needle aliner or controller mounted as the other members, with adjusting means G in slot G. It is a plate .eX- tended between the mounting of the transfer wheel andthe needles and slightly below the wheel. Its pressing edge g has the same curve as the travel of the needles and is substantially on a line with the bottom of the slots of the transfer wheel. Its tip g is slightly pointed out so that vwhen the needles reach the press/er they are engaged by the curved edge aridheld mor supported on a line of travel the same as the curve the cylinf der needles normally travel in.4 They are -thus perfectly adjusted or alined with reference to the wheel and to the cylinder. This presser may be so adjusted that the needlesare all pressed slightly within their normal line of natural outward spring will movement into the slots wheel. The pressing edge, troller extends in the same curve beyond the point where, by the revolution of the transfer wheel, its teeth are carried away lfrom the curved edge of the controller, and beyond the point of transfer. It is found that the needles in the slot or between the teeth are ,apt

to be carried by the transfer wheel. away quicken their of the transfer from the cylinder line 'and be broken or bent.

The controller'or presser, however, prevents this, the edge, g, extending tangent to the periphery of the transfer wheel, or eccentric to the center of the transfer mechanism. l

It will be understood that the two needles which have the' long stitches or loops are the ones that enter the slot and that the wheel is to be formed and adapted to receive them in the slot and between the .portions of the teeth. The other needles pass in the space between the slotted teeth-such number as the pattern requires. b

After the teeth have been forced into the slot and the cloth loosened to permit the loop to cover the head of theother needle or needles it lis necessary that it be pressed down over the heads of the needles and that the cloth or web should be further pressed down inl readiness' for the -next stitch. It provide "a presser near the transfer wheel and farther on. I have devised a single shoe H to meet both theseV needs.

Its tip or for- Ward end h is slightly tapered .upward and linward from the bottom-to engagement of the fabric. :It is held,.by'a

Fromlthe tip the lower edge extends 4 A which is formed and locate to hold the fabric down. Beyond this and before the next feed is the notched presser wheel l which in this'instance is formed with teeth to pass'three needles therebetween at i, l -the teeth i being provided to pressin'or close the ybarb of the fourth was sli ped over thenext needle) so thatthe -stitch is cast off thatneedle and a space or the fabric by the absence of t at" stitch. This presse wheel is to be mounted as-other parts of the device and is cut to correspond with the dividing and castoff wheels and the transfer wheel, it being understoodfthat the several parts described Nearpresser Wheel I, which in the form here shown may be'called a 3 and l cut 'are mounted landing Jwheel I and presser, cast-off wheel I". ofusual form and position,

"both well-known in the art.

It will beunderstood that the style of the fabric may be varied according to the numplaced and which are to' be grouped in the transferwheel and from one or more of which loops are subsequently to be cast-olf: also depending on the number of needles between the set or series on which `long loops are placed. Thus Athe several parts described may be constructedto conformgto a given scheme, the several members coperatingdn a fabric of the desired pattern. l
