In the jdrawlngs, 1 indicates the needle cylinder grooved externally, and hav ng fixe'dthereto to rotate therewith; a. bed 2 for ,t11e ip1-ess is 3 andfOr'webholders 4;. Thei "web holders slideradially and-are operated by the cam d which, 'as in thewell known Banner machine, is substantially fixed in relation to the needle cylinder, having only a liinited rotz'iry or shifting movement to .ccord with the shifting of the point at which the stitches are formed in heel and toe work, said cam being" held after this limited shifting movement has takenplaeo by the stops 5 coming against a lixed' part" part of lily-invention I provide a lulerun'i ring or cage mentioned above in which the sa d pressers are mounted and which nlio'rds means tor securing, accurate moven'ients ol the pres i I ZS as will be hereinafter noted. 1'
The pressers are formed 'wiitli depending stem portions and upper head oortions the latter extending ii'mardlv from the stem portions and presenting proper edge faces to receive and press the n aedle hea la. The head portions of the pres 1 'are. 1e. eled at top and bottom to prev the beards from striking a surface at 1' angles to their line of movement. whiel'. .d cause breakage of the beards and preferably the upper inclined fir-(re. and the inner faces ot'the pressers are grooved us indigated in dotted lines at to better control. the beards,
The web holder bed,
and which presents other adthough the invention is not. limited in thi .m
respect. The pressers are nlso shouldered. at 13*. leaving the back of the head in pro er relation to be engaged by the presser cam 10 adjustabl}: secured at 11 to the 'Y'Qlat-ll'ill) fixed cam ring l above mentioned.
' bed for the web holders is recessed at 12 to receive the cage 8, which carries the series of pressers and furnishes the fulcrum tli for, said cage resting on the ledge 1'3 oi the bed at the bottmn of the recess. The cage is of special formation and is adapted to earry as a body, the whole series of presseii's The so that these pressers tan-be assembled: in
the. cage while the same is 'a-part from its seatinthe bed '2. end then it, together with the whole series of pressers mountedthere on. can be inserted into the recess so that the vholes'eries of pressers are made to assume 3 proper position in relation to the needles and web holders. or the whole series oi? pressers can be removed as one body by taliing' the Cage out from tlie'recess in the b and in placing it or removing it, it is onl portion and a slotted portion 8 in the slots ofwhich the pressers 3 are held by a spring .barid 3 snrroundmg the cage and fitting 1n notches of the pressers neartheir lower portions, the cage along 1ts slotted -wall being" grooved as at 8 to receive said spring band.

at the upper portions oftheir stems.- The upper edge of the solid ring portion affords onwhich the inner face of the stem of the an-edge 8 which serves as av fulcrum point presser bears andabout which it turns when operatedln one direction by the presser cam 10, i. e.,-1 nWardly for pressing or outwardly.
under the action of the spring band. (hen thepresser is in retracted position shown-in Figs. 1, 3, 4, and 5,'the inner edge of the stem bears on the outer face of the intact ring or body portion 8 of the cage, being held in this position by the spring band 3.
stem of the presser tapers downwardly,
I are interspaced. The needles,
""f-fpreSSer by this action.-
' in and out at proper times.= out of work the presser cams are retracted e5 pressers are held purpose, or any presser may and there is suflicient space between its outer edge and the inner wall of the recess to alplow this stem to move outwardly when the head rp'ortion of thepresser is moved inwardly by the cam. The recess is of proper size alsoito accommodate the spring band.
The cage needs nomeans for holding it in position, it simplyresting on the ledge by its own weight and frictionalcontact with the wall of the recess in the bed 2, all pressures being downward. Of course in lifting the cage out-or placing it in, the cainring 4 would first have to be removed and the web holders would also be removed; The against circumferential displacenient by web holders with which they however, would. not bedisturbed. The pressers as a series can be lifted out and shifted to occupy different positions'circuinferentiallyin respect to the needles The web holders slide in radial grooves in the bed 2, and in grooves inthe ring 13 held on top of the needle cylinder, .Any'preis'scr may be removed-and replaced. without disturbing the cage, this being done by simply exerting pressure upwardly on the desired a pair of pliers grasping the head band yielding for this be thrust down its lower end he band yielding for portion, the, spring into position individually, ing beveled and the spring Control of pressers.-I have provided a pressercam mechanism which will be automatically adjustable to set the presser cams \V hen theyare or moved outw rdly away from the circle of pressers, and in this position the yarn, as it shifts from one side of the yarnfinger tothe other in heel and toe work, will not be caught by the presser, and thus interfere with the proper-taking up of the yarn. The presser cams are moved-in and out in alternation. Referring to Fig. 8 the presser cam 10 at the left is in its innermost position ready to perform its function of operating the pressers iiuvardly, and the circle of presser-s is indicated at. 3. The presser cam at the right is in its outermost position The direction of rotation of the needlecircle is indicated by the arrow 3/. Now, when the direction of rotation is reversed, the cam ring upon which the presser cams are mounted is moved for a limited distance in the direction opposite'to the arrow, and until the stop 5 (lower one) strikes against the fixed post 6 to which the arm 17 supporting the yarn feed fingers m, 'm/ etc, are pivoted. This oscillation of the cam ring is usual in the Banner machine to properly position or get the lead of the web holder cam in relation to the stitch point. As soon as this reverse movement of the cam 90 ring begins totake place, the presser cams 10 at the left begin to'move outwardly due to the spring band exerting its forcethrough the pressers, and due to centrifugal force, and due also to the fact that the controlling lever 18 of the presser cam moves away from the surface of the bracket 17, or other part? with which itcontacted to move it to operative position. Therefore this presser cam will be at once retracted and will be out of the way of the strand of the-yarn at .2 extending from the fabric to the central yarn finger At thesame time the lever of the righthand presser cam will be brought agalnst the arnrl 'i' and this presser cami 1 5 will be moved inwardly to operative position to work against the pivoted pressers. From thisarrangement also it will be seen that when the bracket'l'T is lifted for any reason, and the yarn is withdrawn from work, both the presser cams will befree to. move outwardly under the action of the spring band acting through the pressers, and because of this there will be no"danger' of the work being pressed off from the needles should the machine be turned when the yarn finger bracket is'lifted- \VhatI claim is: i 1.
