j Application ined ammini 1i, 1922. serial No. 606,790.

the following is a'spec'lification, referencebeing had to the accompanying drawings.

This invention relates to knitting and more particularly to the transfer of knitted webs,

An object of the invention is to generally improve that type of transfer ring used in applying stitches to the needles of a knitting machine in such operations, for example, as the running-on7 of a rib top of a half hose vpreparatory to theI knitting of the plain web of the leg and foot, and particularly to that specic type of transfer ring in which stitch strippersare employed in connection with the stitch carrying points or quills for the purpose Aof 'stripping the stitches from the points or quills and transferring them to the needles of the knitting machine after the transfer ring has been* properly positioned inicooperative relation or engagement therewith.

Transfer. rings of this type, as heretofore constructed, have been equipped with stitch strippers which were operable in unison to simultaneously transfer all of the stitches from t-he points or quills to the needles. In certain cases it will be desirable to avoid this simultaneous transfer vof stitches and the object of my present invention is to so construct a transfer ring of the type specified that the stitch strippers will be operable individually, andl in succession, to vproduce a correspondingly individual and successive transfer of stitches fromthe points or quills of the transfer ring to the needles of the knitting machine. y

This objectI accomplish 'in V the manner hereinafter set forth, reference bein had to Vthe accompanying drawings, in vwhick Figure I is a top or plan'view ofa transfer ring constructed 1n accordance with the present invention;

Figure II 1s a vertlcal sectional view of the same, illustrating its mannerof application to the needles of a knittingymachine;

Figure III is a view similar to Figure II' showing the positions of the parts assumed at the beginning of the transferring 'operation 5 Figure IV is a horizontal sectional View on the line IV-IV, Figure II; and

Figure V isa vertical sectional view on the line V--V, Figure III.

Proceeding to a detailed description of my invention, 1 indicates a. circular frame having an annular head 2 from which pro-- ject a circular series of stitch carrying points or quills 3. Upon -the frame' 1 are slidablyI mounted a series of stitch strippers, each embodying a stem 6 land anangularly directed strlpping finger 7. The stripi plng lingers extend between the points or quills 3 (which are for convenience hereinafter referredto simply as quills") and are adapted to be projected on lowered to strip the stitches carried by the quills there- *i from and transfer them to the needles 8 of the knitting machine. In Figures II and III of the drawings only those quills,- needles and strippers at diametrically oppo-4 lsite sides are illustrated, in order to avoid unnecessary confusion in the views.

Mounted upon the frame 1 and encircling the stems 6 of the stitch strippers is a cam ring 9 provided with a raceway 10 into which project bits' 11 formed upon the stems" shown in Figure II, and the bits 11 on the stems -6 occupy the rearmost part of the raceway 10. At this time the cam 12 also retracted, as shown in Figure II and by dotted lines, in Figure V. The ring is then applied to the needle bank, each quill 8 with stitch upon it being brought into .cooperative relation or engagement with the correspendingl needle 8, as shown in Figure II.

The cam 12 is now projected or lowered into* the raceway 10, as' shown in Figure III and, by full lines, in Figure V, engaging the bits 11 which are in its-immediate path of movement with correspondingprojection of `stripper fingers 7, as shown in Figure III. The stitches controlled bythe projected stripper fingers are stripped from the quills and impaled. over and upon the needles, and, with the cam 12 .maintained in projected position, 'the earn ring 9 is rotatd about the .frame 1 of the transfer ring. During its circuit, the inclined face from the ring to the knitting machine andl the empty ring may be removed.

The cam ring 9 may be maintained in.

proper relation to the circular frame .1 by any suitable connecting means, that which I have illustrated consisting of pins 14 carried by the frame 1 and projecting into an annular groove 15 in the inner face of the cam ring.

Mechanism of any available type may be used for controlling the position of the cam 12 and for rotating the cam ring 9 about the frame 1. yThat which I have illustrated consists of a transverse bridge 16 secured to opposite sides of the cam ring-and provided with a pivotally mounted swinging plate 17, theA latter having a manipulating handle 18 and also a projecting linger 19 adapted to engage with either of slots 20 or 21 in one side of the cam 12. The linger 19 normally engages the lower slot 20, as shown in Figures I and II, thereby holding the cam 12 in the raised or retracted position. When it is desired to project the stitch strippers, the linger 19 is released from the slot. 20, the cam 12 projected to the position shown in Figure III, and the finger 19 engaged with the slot 21 to maintain the cam 1n projectedy position during its circuit. The handle 18 on the plate 17 is grasped and pushed in the direction of the arrow in Figure I, and the cam ring 9 is thereby caused to rotate about the frame 1, the cam 12 movingirn the directionof the arrow in Figure V.

In order to ensure positive alignment of the points or quills 3 and the needles, I may provide a. projection 22 capable .of engaging a stop 23 on the lixed portion of the knitting machine frame. By virtue of this provision, the transfer device will lbe held against rotation during the manipulation of the handle 18 in the transfer ot' the stitches.

Furthermore, although I have described vthe transfer as accomplished manually it is to be understood that I do not limit myself Yto be engaged simultaneously with all the needles of a knitting machine, stitch strippers individually associated with the quillsv and means for actuating the strippers to successively transfer the stitches between the quills and the needles.

3. In a. web transferring device, the combination of an annular frame with stitch quills adapted to be held stationary with respect to the needles of a knitting machine, stitch strippers individually associated with the quills, and means rotatable on the frame for actuating the strippers to successively transfer the stitches between'the quills and the needles.

4. In a web transferring device, the combination of an annular frame with stitch quills adapted to be held stationary with respect to the needles of a knitting machine, stitch strippers individually associated with the quills, a ring rotatable on said frame,

`ed to be held stationary with respect to the and means carried by the ring for actuating. the strippers tov successively transfer the stitches between the quills and the needles.

In testimony whereof, I'have hereunto signed my name at Philadelphia, Pennsylvania, this 12th day of December, 1922.
