17 Claims.

This invention generally pertains to knitting machines, such as those utilized for the production of seamless hosiery, and is more particularly concerned with a new means and method of effecting terry loops and plating in the fabrics knitted on such machines.

Modern knitting machines of the Banner type utilized for the production of seamless hosiery, such as army socks, are commonly provided with yarn feeding means comprising a plurality of independently operable yarn guides or fingers adapted respectively to feed yarn or different size, quality, material, color, etc, for use either singly, or in desired combination or relation, in knitting different parts of a stocking or sock; the several yarn guides being selectively controlled for individual and combined action as desired, by the standard or conventional patterning means of such machines.

Provision has heretofore been made in such machines to feed the yarn so as to effect terry loops, as well as plating, in certain courses or areas of the hosiery knitted thereby. However, the means provided for this purpose ordinarily involve separate yarn feeding arrangements or devices, one for effecting terry loops and another for effecting plating. Furthermore, the prior art yarn feeding arrangements for effecting terry loops are either incapable of providing such loops in every course of certain areas, such as the heel and toe pockets of the hosiery knitted by the machine, or involve the addition of more or less complicated and expensive installations to the machine.

One object of my invention is to provide a knitting machine of the referred to type having novel means for effecting the production of terry loops in every course of such areas as the heel and toe pockets of hosiery knitted by the machine.

Another object is to provide such a knitting machine having novel means for effecting the production of terry loops in every course of a knitted fabric section resulting from reciprocal knitting action of the machine,

Another object is to provide such a knitting machine having novel means for effecting plating in the fabric knitted by the machine.

A further object is to provide such a knitting machine having novel multiple function means 2 which is selectively adjustable so that it will effect the production of either terry loops, or plating in every course of the fabric knitted by the machine, and during circular or reciprocal knitting action of the latter.

An additional object is to provide such a knitting machine having novel means as indicated which is simple in construction and embodies structural and functional features of advantage over similar means of the prior art.

A further object is to provide such a knitting machine having novel yarn feeding means.

It is alsoan object to provide such a knitting machine having novel yarn feeding means comprising a yarn guide finger embodying new structural and functional features adapted to carry out the purpose of my invention.

Another object is to provide such a knitting machine having novel yarn feeding means comprising a throat plate embodying new structural and functional features adapted to carry out the purpose of my invention.

Still another object is the provision of a novel method of eifecting terry loops and plating in the knitted fabrics produced on a knitting machine of the referred to type.

With these and other objects in view, which will become more readily apparent from the following detailed description of certain illustrative embodiments of my novel improvements shown in the accompanying drawings, the invention comprises the novel elements, features of construction and arrangement of parts in cooperative relationship, as well as the new method, herein- 0 after more particularly defined by the claims.

Fig. 15 is a fragmentary elevational view, similar to Fig. 13, but illustrates the parts positioned as shown in Fig. 14.

In the referred to Banner type and other circular knitting machines, the latch or guard rin of the machine is provided at the yarn feed point with a so-called throat opening within which a plurality of yarn guide or feed fingers are located which are selectively operated by a pattern mechanism in Well-known manner. Usually, the said throat opening has a floor, or throat plate, which serves as a support upon which the active yarn guide finger, or fingers rest, with their delivery eyes in a predetermined horizontal plane close to the needle row. In passing from the active yarn guide eye to the needle hooks, the yarn slides or reeves over the edge of this floor or throat plate, so that such edge, and the terminal corners thereof, normally define the delivery plane or point for any given yarn.

In accordance with the wellknown practice of plating any given yarn upon another, such as a facing yarn on a body yarn, it is important to provide a proper lead angle necessary to cause one yarn to enter the needle hook in accurately spaced relation to the other yarn so as to be plated thereon in uniform relationship. When such plating is to be effected in areas produced by reciprocal action of the needle cylinder, a in knitting the heel or toe pockets of stockings or socks, it is, of course, also important that the mentioned uniform relationship between the yarns be maintained during movement of the needle cylinder in both directions.

As hereinafter more fully explained, the novel plating means of my invention maintains the said uniform relationship between the yarns utilized to effect plating, by feeding the main or body yarn through a yarn guide eye or aperture which is centrally arranged in the throat plate below and transversely of the previously referred to reeving edge, and by the provision of terminal corners at each end of said edge which are substantially equi-distant from said yarn guide eye. By this arrangement, the yarn fed from the yarn guide eye in the throat plate will invariably have the same angular relationship with respect to the hooks of the needles to which the yarn is fed, and also with respect to the second or plating yarn being fed from a certain selected yarn guide finger, constructed in accordance with my invention and positioned above the throat plate in such manner that the yarn will pass over the reeving edge of the latter at the terminal corners thereof. Accordingly, both the main and auxiliary yarn will be fed to the needles in the same determinedly spaced and angular relationship irrespective whether the needle cylinder is moving in one direction or the other.

With the aid of a certain prior art knittin machine mechanism, it ha also heretofore been possible to provide terry loops on the inside of circularly knitted hosiery sections. The referred to mechanism is arranged to feed the terry yarn in such relation with respect to the main or body yarn, that the former will pass over the top edges of the machine sinkers while the main or body yarn enters the throats of the sinkers at the knitting point in conjunction with the movement of the needles through a knitting wave. However, the said prior art mechanism functions to produce terry loops only when the independently operable needle series is moving through its knitting wave in one direction. Consequently, when producing such articles as army socks with terry yarn of wool on the inside of the heel pocket, sole and toe pocket the terry loops can only be provided in every second course with this mechanism during reciprocal action of the needle series, 1. e. during the knitting of the heel and toe pockets. The circularly knitted foot section intermediate the heel and toe pockets is, of course, produced by rotation of the needle cylinder in one direction only, and the said mechanism is therefore capable of producing terry loops in each course section constituting the sole area.

When terry loops are formed only in every second course of the heel and toe pockets there are obviously fewer cushioning loops provided where the greatest wear usually comes and where the cushioning is particularly needed.

In accordance with my invention, the previously indicated mechanism for effecting plating on the inside of every course of the heel pocket, the sole area and the toe pocket, can, by a simple adjustment, also be set to provide terry loops in the same courses.

It is to be understood, therefore, that the novel knitting machine mechanism of my invention is arranged so that it can be selectively adjusted to either effect plating or terry loops with a secondary or auxiliary yarn in every course knitted with a main or body yarn during rotary or reciprocal action of the needles, when producing a fabric or article of the type previously indicated, and that the plating or terrying is effected in connection with the movement of the needle series of the machine through a single knitting wave.

The improvements of my invention may be associated with a conventional circular knittin machine, such for example as a Banner machine, adapted to produce a plain or other circular hosiery fabric, and heel and toe pockets in the usual and well-known manner.

In accordance with one mode of operation, my invention functions to produce terry loops on the inside of a foot hose, or sock, as indicated for example in Fig. 1, i. e., in every course of the high splice section S, the heel pocket H, the foot sole section F, and the toe pocket P.

In accordance with another mode of operation, my invention functions to produce plating on the inside of a foot hose, or seek, a indicated for example in Fig. 2, i. e., in every course of the high splice section, the heel pocket, the foot sole section, and the toe pocket; these sections or parts being identified in Fig. 2 by reference characters corresponding with those of Fig. 1.

To effect proper feeding of the yarn when the knitting machine is set to function in accordance with one or the other of said two modes of operation, I provide novel yarn guide or feeding means in the form of a yarn guide finger shown in Figs. 3 and 4, and a throat plate device illustrated by Figs. 5 and 6. In order to facilitate an understanding of the various pases of my invention, the description will he proceeded with by first pointing out the novel structural features of said yarn feeding means. then explaining the cooperative relationship of said means with respect to the standard parts of a conventional knitting machine, and finally setting forth the operation of the invention in carrying out its intended purpose.

The yarn guide finger 23 is of standard or conventional ize and shape, and is provided with some or all of the parts and features corresponding with the usual guide fingers associated with the particular knitting machine with which it is adapted to cooperate, depending upon the extent to which such parts and features are required or desirable in conjunction with the improvements of my invention. However, instead of being constructed of a single piece of metal or other material, as usual, it i made in two parts identified as 213 and 23 The part 20 forms a continuous extension of the part 2% so that when the said two parts are assembled as shown in Figs. 3 and 4, they form a yarn guide finger which corresponds in size, configuration and other characteristics, substantially with the other standard yarn guide fingers associated with the knitting machine to which it is applied. This feature is of significance in that it permits the ready substitution of my novel two-part yarn guide finger for one of standard construction, without necessitating any alterations insofar as the conventional arrangement and operation of the yarn guide fingers and associated parts is concerned.

The separate front end, or part 20*, of the finger 20 is provided with a vertically extending yarn guide aperture 2|, an extension 22 having an aperture 23 through which passes the shank of a screw 24 in turn secured in a threaded bore between the position shown in full lines in Fig.

3, and the position indicated in dot-and-dash 6 lines in the same figure. Movement of the part 20 beyond these positions is prevented by the complementary abutment elements 26 and 21, as clearly shown.

The throat plate device 28 shOWn in Figs. 5 and 6, is also generally the same in size and configuration as the similar devices ordinarily associated with the latch ring of conventional circular knitting machines, such as the referred to Banner type machines. As usual, the device is of a generally U-shaped configuration and comprises a pair of oppositely arranged side members 29 each of which has a threaded bore 3i in their upper sections arranged to retain the screws which secure the device to the latch ring of the machine. A bottom or floor section 32 extends between the members 29 on which the yarn guide fingers of the machine are adapted to rest when in active position. The front end of the bottom section 32 is provided with an edge 33 over which the yarn from the yarn fingers slides or reeves during its feeding movement to the needles and sinkers. of the machine.

In accordance with my invention, the front end of the bottom section 32 is provided with a transversely extending yarn guide aperture 34, below the yarn reeving edge 33, as shown in Figs. 5 and 6. At the rear of the bottom section there is also provided a suitable yarn guide element 35. At each end of the yarn reeving edge 33 the device 28 is provided with a yarn guide notch 36 adapted to limit the lateral movement of the yarn effected by reciprocal movement of the needle series of the machine while traveling over the reeving edge 33 on its way from one or more of the yarn guide fingers of the machine to the knitting elements as aforesaid.

' By referring more particularly to Figs. 7, 8 and 9 of the drawings, it will become apparent how the novel yarn feeding means comprising the yarn guide finger 20 and throat plate device 28 of my invention, is associated with a standard latch ring 31 of the knitting machine. The yarn guide finger 20 is mounted in position between the usual pair of vertical bearing lugs 33 united with and extending upwardly from the latch ring 31. The finger 20 is arranged for vertical movement between active and inactive position as determined by the usual mechanism of the machine, intermediate said lugs 38, by means of a pin or rod 39 which passes through an aperture 40 in the finger 20 and is fixedly seated in aligned apertures of the said lugs. A second yarn guide finger 50 of standard or conventional construction is shown mounted directly adjacent to the yarn guide finger 2 B; the latter being shown in lowered or active position in Figs. 7, 8 and 9, while the former is shown in raised or inactive position.

The throat plate 28 is secured as usual in a cut out section of the forward lower portion of the latch ring 31, by means of two screws 4| which pass through suitable vertical apertures in the latch ring above the throat plate and are fastened in the threaded bores 3| of the throat plate device 23, as clearly shown.

As usual, the latch ring is pivotally connected at one side with a stationary part of the knitting machine (connection not shown) so that it may be swung vertically from the position shown in Fig. '7, to a position above and to one side of the needle cylinder in which are mounted the usual series of independently operable needles 42, which are actuated in well known manner. An adjust ment screw 43 is vertically mounted as usual in a threaded bore in a portion of the latch ring 31 adjacent to one of the bearing lugs 38, and the lower extremity of this screw 43 rests on a stationary member 44 of the knitting machine, The adjustment screw 43 is commonly provided to determine the vertical position of the throat late 28 and active yarn guide fingers on the latch ring 3! with respect to the needles 42 and sinkers 45, and is fixed in position by means of a set screw 46 threadedly engaged in the side of the latch ring section through which the adjustment screw 43 passes. The end of the set screw 46 is adapted to engage the threads of the adjustment screw 43 and prevent rotation thereof after it has been turned to the right or left to determinedly adjust the height of the said parts on the latch ring relative to the needles and sinkers, as aforesaid.

In order that the latch ring may not be subject to undesirable vibrations during operation of the machine or become accidentally displaced vertically from its adjusted position as determined by the screw 53, there is provided the usual latch or locking member 41 which is pivotally mounted on a screw stud 48 extending into a vertically adjustable plate 49 provided with elongated apertures through which pass the shanks of two screws 52 in turn secured in a stationary machine part 44. The hookshaped upper end of the latch 41 engages a screw stud 53 secured to the latch ring 31, and this engagement is maintained by means of a spring 54, one end of which is secured to the latch 47 and the other end of which is secured to the stationary machine part 44 by means of a screw 55.

When it is desired to vertically adjust the latch ring 31, so as to slightly lower the throat plate 28 and the active yarn guide fingers such as the finger 20, thereby to vary the relationship of the yarn reeving edge 33, and the lead angle of the yarns passing thereover with respect to the needles 42 and sinkers 45, the set screw 45 is turned to free the adjustment screw 43, and the latter is then rotated to an extent necessary to effect the desired lowering of the latch ring (H. The set screw 45 is then again moved into locking engagement with the threads of the adjustment screw 43.

Since lowering of the latch ring 31, as just described, will cause the screw stud 53 to move downwardly away from the hook of latch 41 so that it will no longer be firmly connected to the latter, it also becomes necessary to lower the latch 41 to re-establish such firm connection. This is accomplished by sufficiently releasing the screws 5|, so that the plate l9 on which the latch M is mounted, can be lowered to a position re-establishing the desired firm connection between the stud 53 on the latch ring 3?, and the hook member on the latch'd'l. The screws '51 are then tightened to again fix the plate 49 in position against the stationary knitting machine part 4 as before.

When it is desired to adjust the vertical position of the latch ring 31, so as to slightly raise the same, the latch fill must obviously first be released to permit such upward movement of the ring and stud 53, after which the procedure of effecting the upward adjustment is carried out by substantially reversing the steps previously described.

Moving the hook of the latch 4'! to the left in Fig. '7, against the action of tension spring 54,

until it is free of the stud 53, will permit the latch .ring to be lifted or swung about its usual pivotal connection (not shown) with the knitting machine frame to enable access to the needles and sinkers, as previously indicated.

A vertical bracket 56 is secured to a side member of the latch ring 3'! a usual, having a horizontal plate 51 at its upper end in which are provided the porcelain eyelets through which pass the yarns from the cones or bobbins (not shown) of the machine to the yarn guide elements positioned below the plate 51.

Operation of invention to efiect terrying When it is desired to produce a knitted fabric, such as an army sock of the type illustrated in Fig. 1, in which the body yarn consists of about 50% cotton and 50% wool, and the terry loops are produced with yarn consisting of wool, the novel means of my invention are arranged and operated as follows:

The body yarn B from the proper yarn cone or bobbin is passed through a suitable eyelet in the plate 5'1, through the yarn guide element 35 at the rear of the throat plate 28, and through the yarn guide aperture as below the reeving edge 33 at the front end of the throat plate and directed to the needles 52 in usual manner when operation of the machine is about to commence. The terry yarn T is similarly taken from the proper yarn cone or bobbin, is passed through a suitable eyelet in the plate 51 located to the right of the yarn guide finger 20 (Fig. 8), so that it may be extended downwardly from said eyelet to the left and through the yarn guide aperture 2| of the yarn guide finger 28, and then directed to the needles 32, over the reeving edge 33 of the throat plate 28 at the left end yarn guide notch 36, as shown in Fig. 8, to effect the production of terry loops in the manner about to be explained.

Figs. 8, 9, 10 and 11 illustrate the action of the independently operable serie of latch needles 42 and cooperating sinkers 2-5 during feeding thereto of the body and terry yarns by the novel yarn feeding means of my invention to effect knitting of the body yarn into plain loops and the joining therewith of terry loops.

When the independently operated needles 42 move to the left, as indicated by the arrows in Figs. 8 and 9, the body yarn B, after it leaves the aperture 33 at the front end of the throat plate 28, is fed to the needles as shown in said figures, at a lead angle such that it will enter the throats 05 of the sinkers 45, substantially at the knitting point, or where the needles 42 and sinkers d5 cooperate to form successive plain stitches in connection with the carrying out of a single knitting wave by the latch needles 62 in accordance with the known practice. Simultaneously with the formation of the plain loops by the body yarn, the terry yarn T, after it leaves the aperture 2! of the yarn guide finger 20 and passes over the reeving edge 33 at the left end notch 35 of the throat plate 28 as shown, is fed to the needles s2 and sinkers 45 at a lead angle such that it will pass over the tops '25 of the sinkers, substantially at the said knitting point, to form successive terry, or lengthened loops, in connection with the carrying out of a single knitting wave b the needles 42.

In this connection it is noted that prior art means have heretofore been employed to feed the yarn to the needles and sinkers as above described to effect the formation of combined plain and terry loops. However, the said prior art means is capable of such operation only when the needles are moving in one direction and it is particularly emphasized, therefore, that the yarn 9 feeding frieans of my invention does not merely differ from said prior art means insofar as the structural variations are concerned, but that the means of my invention is additionally designed and arranged to effect this same result when the needles are moving in the opposite direction, or to the right, as will become clear by next referring to Figs. 10 and 11.

As there shown, rotation of the needles to the right will result in correspondingly moving the body yarn B and the terry yarn T to the right side of the throat plate 223. When this takes place, my novel yarn feed means will cause the body and terry yarns to be fed to the needles and sinkers in the same relationship as before, but in order that this be accomplished with the terry yarn '1', it will be noted that the part 20 of the yarn guide finger 2!! is pulled or moved laterally by the terry yarn T so that the latter occupies the same relative position with respect to the reeving edge 33 and the right 'end notch 36, as it did with respect to the reeving edge and the left end notch 36 when the needles were moving to the left.

It will be understood, therefore, that the angular relationship of the body and terry yarns relative to the needles and sinkers is the same irrespective whether the needles of the machine are moving to the left or right. Furthermore, that this angular relationship of the two yarns B and T relative to the said knitting elements is maintained by reason of the central location of the yarn guide aperture 34 from which the body yarn B moves to the knitting point, with respect to the two yarn guide elements or notches 36 from which the terry yarn T is fed to the same point as determined by the cooperatively associated yarn operated movable part 20 of the yarn guide finger 2E1.

Operation of invention to efiect plating When it is desired to produce a knitted fabric, such as a foot hose of the type illustrated in Fig. 2, in which certain parts are plated on the inside as previously pointed out, the novel means of my invention are arranged and operated as follows:

Assuming that the machine is set or adjusted to operate as above described so as to produce a fabric with terry loops, then the terry yarn is replaced by a suitable auxiliary or plating yarn A. Thereafter it is merely necessary to lower the latch ring 37 (in the manner previously described) to the extent necessary to bring the yarn reeving edge 33 into such relationship with the sinkers of the machine, that the angle of the plating yarn is altered or reduced sufficiently so that the same will enter the th'roats 45 of the sinkers 45 at the knitting point. This will be accomplished by lowering the latch ring 31 approximately inch from the position which it occupies during operation of the machine to produce terry loops, as indicated by the dot-and-dash lines in Fig. 9.

Figs. 12, 13, 14 and 15 illustrate the angular relationship of the body yarn B and a plating yarn A with respect to theneedles and sinkers, and the manner in which both yarns enter the throats 45 of the sinkers 45 at the knitting point, after the latch ring has been lowered in the above noted manner. Figs. 12 and 13 show the relationship of the parts previously described when plating takes place during movement of the needles to the left, and Figs. 14 and 15 show the relationship of the same parts when plating takes place during movement of the needles to the right.

When operating the knitting machine to produce either the foot hose of Fig. 1, or that shown in Fig. 2, the various constituent parts thereof are, of course, formed by rotary and reciprocal knitting in accordance with the usual and wellknown practice. The leg portion down to the heel pocket H is eifected by rotary knitting, the heel pocket by reciprocal knitting, the foot section F between the heel pocket and the toe pocket P by rotary knitting, and the toe pocket by reciprocal knitting.

When it is desired to introduce terry loops or plating on the inside of the hose in conjunction with rotary knitting, as for example in the high splice area S, or the foot sole area F, a usual yarn guide finger 50 (Fig. 7) may be employed instead of the yarn guide finger 20, and the latter raised to inactive position. In accordance with the well-known practice, the yarn guide finger 50, when arranged to feed an auxiliary yarn, may be automatically operated by the standard pattern mechanism of the machine, so as to feed its yarn to the knitting elements only during that portion of rotation of the needle cylinder. during which the terry or plating loops are to be combined with the plain loops eifected by the body yarn. During the remainder of the course or courses so produced the finger 5!] is automatically raised to inactive position by the said patterning mechanism so that the auxiliary yarn is not interknitted with the body yarn, but is merely floated across the course section produced by the latter, as well understood by those skilled in this art.

Of course, the novel improvements and method shown and described, may be changed and modified in various ways without departing from the invention herein disclosed and more particularly defined by the appended claims.
