20 Claims.

This invention relates to knitting apparatus involving needles and associated elements of special types.

An object of the invention is to provide a needle 5 arrangement for a knitting machine having improved characteristics with respect to controlling operations exercised thereon or exercised by it in the knitting of a fabric. Another object is to in-. corporate in a needle slot special means for facili- 10 tating the transfer of the stitch from one type of needle to a different type as in a machine employing both cylinder and dial needles.

These objects may be accomplished in the following manner in accordance with the preferred is embodiment of the invention in the assumed casev where it is desired to transfer the stitch from a cylinder needle to a dial needle or vice versa. Each of a plurality of slots in the cylinder or dial contains a needle shank and another strip of go metal which may be called a spreader. Normally the needle shank and the spreader are in intimate and sliding contact with each other in the needle slot with the needle shank capable of being ad-, vanced or retracted without disturbing its as- :5 sociated spreader. For example the spreader and the needle shank may comprise fiat metal strips placed side by side in the needle slot. Means may be provided for advancing simultaneously a needle shank and its spreader and subsequently causing a further advancement of the spreader to produce a separation of the upper ends of the spreader and needle sufl'icient to permit another needle to be inserted between the spreader and first needle and take over a loop of yarn supported up to that time on correspondingly spaced shoulders on the spreader and first needle. Above this shoulder on the spreader, the spreader may terminate in a curved tongue directed towards the associated needle shank and normally riding in a 0 lengthwise groove in the needle shank except when the stitch is to be transferred. The spreader may also embody a cam turned towards the needle shank and riding in an elongated slot cut into the rear or front edge of the needle shank when the i spreader is stationary and the needle is advanced or retracted; but when the spreader is advanced with respect to the needle shank the aforesaid cam rides out ofthe slot and hence causes the desired separation between the upper ends of the needle and spreader to allow for entrance therebetween of the other type of needle.

This type of construction permits its use in fine gauge machines since both pieces in a slot lie flat against each other for normal knitting and hence require a slot no wider than the combined the invention;

' 20 in the positions shown;

(01. sis-24) a minimum of longitudinal movement. Another advantage is that the spreader when it enters a loop, it does so by opening sideways with very little 5 cutting action as in the prior art where the spreader is usually wedged into the loop as the spreader moves forward.

This invention will be better understood by reference to the following detailed description taken in connection with the accompanying drawings in which a Fig. 1 is a general view of a fragment of a knitting machine showing one dial needle and one cylinder needle embodying one form of this invention;

Figs. 22 and 23 are section views taken on Fig.

Fig. 24 shows another form of the invention 5 where the separation of the needle and spreader is accomplished by a cam acting on the needle slot; and

Fig. 25 illustrates the manner in. which the yarns may be fed to the needles of this inven- 5 tion. a f Fig. 1 is a fragmentary view of a knitting machine showing one dial needle slot and one cylinder needle slot each having a needle-spreader combination of this invention. Thus. may be 35. applied to a beard a dial and 21 a cylinder of a knitting machine. The slot in the cylinder comprises a needle28 and a spreader 29 as shown more clearly in Fig. 2. The dial slot has a corresponding dial needle 28' and spreader 29 separated in a manner to permit the stitch to be transferred from the dial needle to the cylinder needle.

The details of the combination in each slot will be understood by reference to Fig. 2 where the needle shank is terminated in a latched hook 30 and a shoulder 3|. One side of the needle shank has a lengthwise groove 32 extending between the points 33, 34. The edge of the needle shank opposite the latch has an elongated slot 35 cut therein between shoulders 36, 31. The lower end of the shank has a long narrow butt 38 for cam operation as will be described later. The associated spreader 29 has a shank of substantially the same width and thickness as the needle shank. The upper end of the spreader termi-- nates in a curved prong or hook 39 bent towards its associated needle, the tip of the hook 39 being designed to normally ride in groove 32 when the needle and spreader are placed side by side in a needle slot. Below prong 39 is a shoulder 40 intended to be aligned with shoulder 3| of the needle when a stitch transfer is taking place, as will be described later. The front edge of the spreader has butt 4| which is short and wide compared to butt 38 of the needle. At a substantial distance below shoulder 49 the rear edge of the spreader has, awedge shaped cam 42 projecting at right angles to the side faces .of the spreader. When the needle and spreader are placed side by side in a needle slot this cam 42 is designed to lie in slot 35 as the needle is advanced.

and retracted. But if we assume that the spreader is advanced with respect to the needle it will be apparent upon inspection of Fig. 2 that the advancement of the spreader will ultimately cause the upper angular face of cam 42 to contact against shoulder 31 and finally cause the outer point of cam 42 to ride on the adjacent face of the needle thereby separating the upper ends of the spreader and the needle a distance equal to the effective height of cam 42.

Various views of the needle-spreader combination of Fig. 2 are shown in Fig. 3. In position A the spreader is in its fully retracted position while the needle is in a fully advanced position. Cam 42 is in slot 35 near shoulder 36 and prong 39 in near the lower end of groove'32. The position A may be secured by the passage of a thin cam which contacts with butt 38 but not butt 4|.

Position B shows spreader and needle after both have been advanced by a cam contacting with both of butts 38, 4|, with another cam subsequently acting only on butt 4| to further advance the spreader with respect to the needle to produce their separation. This means that cam 42 rides out of slot 35 and the point of cam 42 is in contact with the inside face of the needle shank to get the desired separation between the upper ends of the spreader and .needle for stitch transfer, with shoulder 40 on the spreader in alignment with shoulder 3| on the needle. Position B is there.- fore the position for receiving another needle between needle 28 and spreader 29 for stitch transfer.

Position C shows the needle and. spreader both infully retracted position and shows clearly the difference in height of the bottom faces of butts tion 0 the prong 39 is resting in the groove 32 and cam 42 is in slot 35.

When the needle and spreader are in position C an advancing cam of staggered configuration may strike both butts 38, 4| to raise them simultaneously to the position D of Fig. 3 after which another cam acting only on butt 4| may further advance the spreader 29 to the condition of position C, Fig. 3. That is, as soon as the needle has reached the height of position D it is no longer advanced but the spreader is advanced to give the condition of position B.

In Fig. 3 just described the needle holder 44 may be the needle cylinder or the needle dial of a circular knitting machine as will be obvious to those skilled in the art. 'Of course holder 44 may have a needle spreader combination in each slot.

After the explanation of Figs. 2 and 3 it will be apparent that the dial needle-spreader of Fig. 1 has just been advanced by a cam (not shown) to the position D of Fig. 3 and that the spreader is now being actuated upon by a cam 45 to shift the spreader with respect to the needle to reach the separated condition of position B so that the cylinder needle of Fig. 1 when advanced to the position shown in dotted lines will be prepared to transfer to itself any yarn loop held by the cylinder needle.

4 is an enlarged rear edge view of the needle and spreader of Fig. 2 in position D of Fig. 3. Cam 42 is in slot 35 below shoulder 31 and prong 39 rests in groove 32.

In Fig. 5 the needle and spreader are in the same relative position as in Fig. 4 but Fig. 5 is a side view.

Fig. 6 is a cross section taken along the line 66 of Fig. 5. It shows the needle slot containing the needle shank 28 and the spreader 29, with the curved prong 39 riding in the bottom of groove 32. Fig. 7 is a cross section taken along the line 1-1 of Fig. 5 at a point adjacent cam 42. It shows cam 42 bent at right angles to the main body of spreader 29 and fitting in slot 35 of the needle.

Fig. 8 is an enlarged view of the needle-spreader of Fig. 2 showing them in a partially advanced position but with cam 42 still riding in slot 35 below the top 41 of the needle slot in needle cylinder 46. Fig. 9 is a further advanced position with cam 42 out of slot 35 and riding on the face of the needle shank producing the desired angular separation between the shank and spreader.

Fig. 10 illustrates an alternative form of the invention in which the separating cam instead of being located on the spreader is located on the needle shank. Thus in Fig. 10 the rear edge of the needle shank 48 has'a wedge shaped cam 49 bent at right angles to the main body of the shank and in the direction of the associated spreader 58 which has a slot 5| on its rear edge between shoulders 52, 53. This is just the reverse of Fig. 2 but it will be apparent that the effect will be the same in angularly separating the upper ends of the spreader and needle when shoulder 53 rides over the inclined face of cam Fig. 11 discloses still another modification in which the spreader 54 has a separating cam 55 and the needle shank 56 has also a separating cam 51, both cams being wedge shaped and having parallel opposed edges 58, 58. -When such a spreader 54 is advanced relative to the needle it is obvious that the contacting cams will separate the spreader and the needle as shown in Fig. 12 where the extreme end of cam 55 is riding on edge 60 of cam 51. The end GI of another needle is shown in Fig. 12 between the separated needle and spreader ready to remove the loop 82 from needle 56. I

In Figs. 1 to 7 inclusive it has been assumed as disclosed in certain of the figures that the slot containing the needle-spreader combination is of uniform width particularly near the top 01'- the needle cylinder. In Figs. 8 to 12 however theupper part of each cylinder needle slot is of increased width fora substantial distance from the top of the cylinder on the side of the slot adjacent the spreader. Thus in Fig. 8 the needle slot is of increased width from the top of the needle cylinder down to the shoulder 53. Therefore when the spreader 28 is moved relative to the needle to bring cam 42 out of the slot the separation 01 the needle and spreader is due entirely to the bending of the shank of spreader 28 while the shank oi needle 28 remains straight as shown in Fig. 9 because of being supported by the vertical wall of the needle slot.

On the other hand if the needle slot is of uniform width as in Fig. 3 the separation cam 42 can not be eifective until it is above the top of the needle cylinder so that-in. such a case the needle shank and the spreader shank bend equally providing that they are of equal stillness or thickness. This point must of course be taken into consideration in providing the holding cam such as cam 25, Fig. 1, for holding the needle while its associated spreader advances.

If only the spreader shank bends as in Fig. 9 it is a parent that this must be taken into considerat on in having the dial needles oil'set from the cylinder needles. Thus the dial needles 18 of Fig. 13 are slightly oiiset from their respective cylinder needles 1I. When the cylinder needles H are advanced as shown at the right of Fig. 13 each cylinder needle remains straight but its associated spreader 12 when advanced is bent to a substantial degree to ro e the necessary space for the entrance of. the d al needle between the cylinder needle and its spreader.

If both the cy nder needle and its s reader b nd away from the verti al hen each dial needle should be ali ned wi h the no mal o t on of i s cylinder needle as s wn in Fi 14 whe e to theleft of the figure the retracted cylinder needles 13 are-in alignment with the dial needles 14 wh le at the right of the figure it is shown how both the cylinder needle and its spreader both bend away from the vertical to pass on opposi e sides of the extended axis of each dial needle-14.

This invention of course is not limited to needles of .the latch type but may be used with other types ofneedles. Fig. 15 is a fragmentary showing of this invention applied to a beard or spring needle. Except for the beard in place 01' the latch the construction is the same as in Fig. 2. The beard needle 15 has a shoulder 18 which is aligned with the shoulder 11 on spreader 18 when a stitch transfer is to be made. Prong 18 on the spreader normally ridesin a lengthwise groove 88 in the side face oi the needle and separating cam 8I rides normally in a slot located in the rear edge 01' the needle. The method of operation is similar to that previously described.

Figs. 16, 17, and 18, illustrate how cam means 1 may be employed to advance selectively a cylinder needle and its associated spreader and these figures may be assumed to have a needle and spreader oi the type of Fig. 2. We may assume that cam 82 is a rotating cam in acircular knitting machine ior fully advancing each cylinder needle and its associated spreader to position D of Fig. 3. Thus in Fig. 16 cam 82 contacts simultaneously with butt 38 and butt 4| to fully ad- 7 vance the needle and its spreader to position D,

of Fig. 3. In Fig. 17 cam 83 operating subsequently to cam 82 contacts with the lower projecting butt I to bring the bottom of butt 4i up to the bottom of butt 38 to shift spreader 28 from position D, Fig. 3, to position B, Fig. 3. Fig. 18 shows a retracting cam 84.01 such a size as to contact with both butts 38, ll of each needle in the needle cylinder to first close the spreader 28 against the needle and then to fully retract both elements-to the position C Fig. 3.

In some instances it may be desirable to have only certain of the spreaders in the needle row advanced while leaving the remainder of the spreaders retracted. 'For this purpose as shown shown in its clockwise position where the lower end" 01' member 85 lies in the path of an advancing cam 88 to fully advance the spreader to the position shown at B, Fig.- 3, while the corresponding needle is being advanced by another cam 80. The spreader of Fig. 19 may be subsequently retracted by a cam (not shown) contacting with the upper armor pivoted member 85 when the said member is in its counterclockwise position.

Still a different form of the invention is shown in Figs. 20 to 23. spreader and its needle have been placed side by side in the needle slot while in Figs. 20 to 23 they are placed edge-wise in a narrower slot. Thus in Fig. 20 the spreader 8i is placed edgewise of the needle shank 82, that is the needle and the spreader are in the same plane. The upper portion 83 of the needle shank 82 including shoulder 84 is recessed, that is, it may be only one half as thick as the main body of the needle shank. In this recess 88 rides the prong 85 of the spreader. Lower down on the needle shank is a special butt 86 of full needle shank thickness between points 81 and 88, and tapering in thickness from point 88 to a knife edge at 88. The spreader has a yarn I82 of the spreader fits into the tapered portion of the butt 85 of the needle to Join the spreader and In theprevious figures the normally ride up and down with the needle in ordinary knitting but when a stitch transfer is desired the spreader is individually advanced by a cam operating on butt I34 after the needle is fully advanced. This will cause cam surface I28, I32 on the spreader to ride up tapered slope 98, 99, producing a lateral separation of the upper ends sufficient for theentrance of another needle between the disclosed needle and its spreader when yarn receiving shoulders 94, I25 are aligned. This action of course also spaces prong away from the needle shank. This separation is intended to take place after the upper ends of spreader 9| and needle 92 project beyond the needle slot. The normal overlapping of the spreader and needle shanks does not require any increase in size of the needle slot containing them over that required for an ordinary needle or needle 92, since the overlapping does not result in any increased thickness except when the parts above the needle slot are separated in the manner above described.

Fig. 21 is an edge view of the combination of Fig. 20 and Figs. 22, 23 are sectional views taken along the designated lines in Fig. 20. Further details of these figures are believed unnecessary except to point out that Figs. 22, 23 show very clearly that the maximum thickness of the needle shank and the maximum thickness of the spreader eachequal the width of the needle slot.

Fig. 24 illustrates an arrangement whereby the separation of the spreader and needle is secured by a cam on the spreader acting against a shoulder on the needle cylinder instead of on the associated needle shank. Thus a fragment of a needle cylinder IOI is disclosed, each slot therein having a needle shank I02 and a spreader I03. The needle shank has a shoulder I04 which is aligned with shoulder I05 on the spreader when preparing for transfer of a yarn loop as shown at the right in Fig. 24. The needle shank and the spreader are placed edge to edge in the slot as in Fig. 20, with prong I09 of the spreader riding in a recess III in the needle shank as in Fig. 20. However the spreader of Fig. 24 and its needle always move together in the normal advancement and retraction of the needle for ordinary knitting as compared with spreader 29 which remains stationary under those conditions. Additional cam means may be used to raise the spreader to provide the-separation. The rear edge of each spreader has a wedge shaped cam I01 turned at right angles to the face of the spreader and adapted to lie normally in a notch I08 in the. needle cylinder below shoulder H0. The needle slot is' not of uniform width but at the top has a forward section of, increased width (as in Figs: 8 and 9) between faces H2, H3. When the spreader I03 is advanced from the ".position shown at the left of Fig. 24 the upper angular face of cam I01 will contact with the inside edge of shoulder IIO causing the spreader to be bent angularly away from its needle asshown at the right in Fig. 24, where shoulders I04, I05 are aligned but separated by a gap wide enough for a dial needle to enter for stitch transfer purposes. The separation of the needle and spreader in Fig. 24 is therefore due to the action of cam I01 on a projection of the needle cylinder.

Fig. 25 represents. a desirable way of feeding yarns to a machine in which both the dial and the cylinder needles are of ,the needle-spreader combination of this invention permitting yarn to be transferred from the cylinder needles to the dial needles or vice versa. Needles II6 are dial needles each with a spreader as provided herein. Needles III are cylinder needles each with a spreader as provided herein. II8 represents a yarn' feed positioned to feed yarn to the cylinder needles when the cylinder needles are in their maximum advanced position; I20 represents a yarn feed positioned to feed yarn to the dial needles when the dial needles are in their maximum advanced position; and H9 represents a yarnfeed adapted to feed yarn either to the dial'needles or the cylinder needles when they are partially advanced as shown at position H for example. This combination of the three yarn feeds just described and the needle-spreader arrangement of this invention is capable of producing many attractive features in the fabric knitted thereby.
