  • the plates 51 may be adjusted to Vary the position of the rollers 5S in relation to the canming surface of the cam rims 58'. This adjustment is for the purpose of determining the desired number of needles over which the transfer combs III-I5 and Ill-I8 will be moved by the control mechanism. Obviously by setting the rollers 58 nearer to. or further away from. the lowest point of the' camming surface of the cam rims the action of said surface .on the roller 'will be advanced or retarded and, accordingly, cause the initial movement of the transfer action to occur sooner or later during the operative function of the transfer bar control mechanism.

Therefore, if the roller 56 is initially set at the position IP, said roller will start to move from the position IP only when the point PI has reached the level L--L.
  • the roller is initially set at the position 2P, it will remain unaffected until the point P2 has reached the level L-L. It will be understood that the positioning of the roller 56 in relation tothe camming surface of the rims 56' is attained by setting the connection between the plates 51 and their respective transfer bars and by regulating the stops 60 and 8
  • I find it preferable to displace the small transfer combs I5 and I6 for a greater number of needles than the large transfer combs I3 and I4. That this mode of operation may be obtained, the stops 62 are adjusted to rest at a predetermined distance from the associated stop blocks 63 on the transfer bars lI1 and I9 respectively carrying said large transfer combs I3 and I4.
  • the distance indicated by the arrow G between the stops 62 and the stop blocks 63 preferably correspond to the distance of one needle so that the transfer bars I8 and 20 to which the plates 51 are directly connected, will move for a distance corresponding to one needle Withthe initial movement of said plates, whereas the transfer bars I1 and I9 will remain stationary and begin their movement only when the stops 62, during the continued movement of the plates 51, have been brought in contact with the stop blocks 63.

  • the distance G referred to is also assured by reason of the fact that the stops 6I carried on the plates 51 are normally urged against the abutting surface by springs 8I.

  • the loops 93 and 94 having been thus transferred on the needles of my improved machine, the same is now ready for operation.
  • the carriers are actuated in the well known fashion to lay the yarn or yarns across the knitting needles I0 and II soas to knit the courses 96 of the heel fabric 81.
  • the loops 94 are gradually transferred for interknitting engagement with said fabric by operation of the transfer mechanism already described.
  • the loops 94 on-the non-knitting needles I2 may be transferred the distance of one or more wales, as necessity or preference may dictate.
  • Figure 14 I have illustrated the single wale transfer. According to this mode of operation of knitting the heel tabs and simultaneously joining the sole portions thereto, the transfer fingers 82 and 83 descend through the usual dipping motion of the knitting machine, pick all the loops 94 off the nonknitting needles vI2 and simultaneously transfer said loops one needle distance, which places each end loop successively in engagement with the end knitting needle of the row of needles I0.
  • An intermediate course may be knitted on the needles I8 between each transfer operation to provide the necessary fabric for the -formation' of the heel and to insure sufficient elasticity to the foot. This operation is repeated until all the loops 94 on the non-knitting needles I2 have been transferred the distance of one needle at a time and interknitted to form a seam 91 uniting the sole portions 89 to the heel-tabs 92.
  • the transfer operation causes the marginal loops of the foot fabric to become interlooped with the adjacent marginal loops of the heel tab fabric and, accordingly, no seaming operation is necessary to unite ⁇ the same. Further, due to the transfer of the loops in the manner specified, the foot fabric is turned automatically at substantially right angles to the leg fabric, a's shown in Figure 15.

- Application April Z7, 1937, Serial No. 139,129
51 Claims. (CL 66-82) The present invention generally relates to full fashioned or flat knitting machines, and particu- -larly to that type 0f machine intended to knit the heel portions into so-called single unit stocking blanks. More specifically, the invention contemplates a mechanism devised to produce the stockings constructed in accordance with the method disclosed in my co-pending application, Serial 'Number 106,828, led October 21, 1936.
It is a well recognized fact that full fashioned stockings, wherein the leg and foot are knitted on a single machine, inherently possess certain advantages' sought for, but seldom found, by the purchasing trade in the ordinary type of full fashioned stocking, wherein the leg is knitted on one machine known as the legger, and the foot is knitted on another machine known as the footer. Among such advantages are perfection and uniformity of matching and texture throughout the entire sheer portion of the stocking, which is present in the foot as Well as the leg; yet the purchasing public has heretofore been denied these advantages because the manufacture of single unit type of stockings has been limit'ed, and practically prohibited, due to the fact that the heretofore known methods devised for their production are rather involved and require expensive outlay, obviously placing the cost of manufacture on an exceedingly high scale and consequently necessitating a comparatively high selling price.
As generally known in the art, the leg portion and the foot portion of a single unit full fashioned stocking blank are knitted contiguously on one and the same machine. Heel tabs are subsequently knitted as a continuation ofthe leg portion, and after-'the blanks, with the completed heel tabs, are removed from the knitting machine,.the heel: tabs are`l looped to the adjacent section of the foot portion to form the stocking. This mode of procedure necessitates the utiliza'- tion of complicated machinery which, coupled with the required additional looping operation, places the cost of the single unit stocking production far above that of the ordinary full fashioned stocking and thus prohibits the sale of single unit goods at -prices reasonably competing with those of full fashioned stockings knitted in accordance with the old standard method, which emplfys two distinct and separate machines re,- spectively known as the legger and the footer.
The present invention, therefore, seeks to Drovde a me-hanism having an utmost simplified construction and capable of doing away with the .heretofore needed additional looping operation for the completion of the stocking which makes it possible to manufacture full fashioned stockings of the single unit type at a cost substantially at par with the manufacture of ordinary two unit type of full fashioned stockings, so that the public may be given the benefits 0f the advantages existing in single unit stockings.
It is the primary purpose of the invention to vprovide a mechanism capable of knitting a heell fabric onto the leg and foot portions of a single unit stocking blank while simultaneously interknitting the foot portion with the heel fabric as the knitting thereof progresses.
The invention is particularly `characterized in that my improved mechanism may be embodied in an ordinary footer, which may be converted in order to accomplish the results of the invention,
thus eliminating one of the greatest obstacles to the manufacture of single unit stockings, which obstacle arose' from the apparent necessity of requiring completely revised and rebuilt machines of complicated and expensive construction.
. The invention is further characterized by the fact that my improved mechanism is adapted to operate for automatically transferring the foot fabric of a single unit stocking blank for direct interlooping connection with the heel fabric during the knitting of the latter, whereby the leg,
y heel, and foot become contiguous and integral parts.
Other important objects and advantages of thev invention will be in part obvious and in part pointed out hereinafter.
In order that the invention and its mode of opq eration may be readily understood by those persons skilled in the art, I have, in the accompanying drawings and in the detailed description based thereupon, set out a possible embodiment of the Figure 5 is a detail in front elevation of certain elements of the transfer comb control operating means.

With more particular reference t the drawings, wherein like characters o f reference will designate corresponding parts throughout, it is to be understood that I have shown only those parts of a full fashioned hosiery knitting machine which are essential to the clear understanding of the present invention, the basic structure of `the f knitting machine itself being that of the commonly used footer with which anyone skilled in the art is Well acquainted.
In the drawings illustrating the preferred embodimen't of my invention, the usual machine frame is indicated at I and carries the center bed 2 about which are mounted a plurality of spaced knitting sections, designated in their entirety by the reference character 3. Each knitting section 3 essentially comprises the needle bar 4, the knock-over bits 5, and the dividers 6. The thread or yarn is fed to the knitting sections 3 by means of the carriers 'I depending from the carrier rods 8 mounted for reciprocation in the carrier rod bracket 9. The relative position, essential operation, and function of the needle bar, knock-over bits, dividers, and carriers are .well known by those skilled in the art and, therefore, need not be described in detail herein.
In accordance with the present invention, the needle bar 4 differs from the usual construction in that it is provided with two sets of knitting needles I0 and II, respectively, each disposed on the opposite end portions of the needle bar 4, and an intermediate set of non-knitting needles I2 arranged on the needle bar 4 between the two sets of knitting needles. Y
The sets of knitting needles I0 and II, of course, are adapted to knit in the usual way and, in accordance with the invention, each set is associated with one or more thread feeding carriers which, through the normal operation of the knitting machine, feed the yarn or yarns back and forth over said knitting needles.
As shown, the non-knitting needles I2 preferably consist of needles having short beards which prevent the loops in engagement therewith from being pressed off, in the manner and for the purpose to be later specified.r It is also possible to use ordinary knitting needles, instead of shortened beard needles, and in this event the usual presser edge, which is disposed opposite said needles, may be removed so that the needles will not press off, or the needles may be so mounted as to be moved away from their associated presser edge which will likewise prevent pressing off.
Associated with the non-knitting needles I2 are a pair of adjacent large transfer combs I3 and I4 respectively, and a pair of small transfer combs I and I6, one of the small transfer combs being disposed on the outer side of one of the large combs I3, and the other small comb I6 being disposed on the outer side of the remaining large comb I4. The combs I3, I4, I5, and I6 are each individually connected to a separate transfer bar, as shown at I'I, I8, I9, and 20 respectively, said transfer bars being slidable in spaced brackets 2I supported upon a shaft 22 rigidly connected to an arm 23 secured to a rocking shaft 24 mounted in bearing 25 upon the rear portion of the knitting machine I.
Arranged over certain of the knitting needles I0, II of each knitting section 3 are narrowing combs 26, 21 respectively, mounted upon rods 28, 29 slidably received in bearings 30', provided vupon the transfer bar brackets 2 I.
As more clearly represented in Figure 3 of the drawings, the narrowing comb 26 mounted on the rod 28, and the narrowing comb 21 mounted on the rod 29, are intended to move inwardly of the knitting section or in the directions indicated by the arrows A, B, whereas the sets of transfer combs I3, I5 mounted on bars I1, I8 and the sets of transfer combs I4, I6 mounted on bars I9, 20 are intended to move outwardly of the knitting section or in the directions represented by the arrows C, D.
The mechanism for imparting the relative movements of the various transfor combs in the manner above stated will now be described.
Arranged in the central portion of the knitting machine is a narrowing head consisting of a pair of narrowing nuts 30, 3| each in engagement with a screw threaded portion 32, 33 of a spindle 34 rotatably mounted in a plurality of spaced paralleling supports 35 rigidly secured to the xed shaft 22. It is to be noted that the screw threaded portions 32, 33 of the spindle 34 are formed to extend in opposite directions so that, with the rotation of said spindle 34, lthe respective narrowing nuts will move in opposite directions, for the purpose to be hereinafter set forth.
The spindle 34 is rotated by means of a pawl and ratchet mechanism which consists of a ratchet wheel 36 acted upon by a dog 3l actuated by a rod 38 connected to one end of anoscillating lever 39 pivoted at its intermediate portion upon the machine frame I, as shown at 40, and having at its other end a roller 4I adapted to coact with a cam 42 mounted on the main cam shaft 43, capable of shogging in the usual fashion during the normal operation of the knitting machine. Thus, with the rotation of the main cam shaft 43, the cam 42, when brought into operative relation with the roller 4I by the Shogging of said `main cam shaft, will act upon the roller and cause the lever 39 to oscillate about its pivot 40 for reciprocating the rod 38 and accordingly operate the dog 3'I to actuate .the ratchet wheel 36 imparting rotation to the narrowing spindle 34 which, by reason of its construction, will cause the narrowing nut 30 to move in the direction indicated'by the arrow E 2,319,769 43 fsi in Figure 2. The rouer ss is heid in positive and the narrowing nut 3| to move the direction indicated by the arrow F'in Figure 1.
I tigidly-con'nected to the narrow nuts 38 and 8l by means of integral wings' 44 are sleeves 45 and 448, respectively slidable on .shaft' 22 and each provided with an labutment 41 disposed to contact a stop 48 adjustably carried in a support 49, onesuch support being fixed to eachof thek nar- I- rowing comb carrying rods 28, 29. The stops 48 are constantly urged inclose contact'with their l respective abutments 49 by means of springs suitably connected to the rods 28 and 29 or their associated elements and to some convenient sta- Iridingengagement with the cam 84 by means of a spring 88 connectedlto the lever 88 and to a suitable portion of the machine frame, as shownY at 89 in Figure 2.
Guided in a forked bracket 18 connected to the front table 1I of themachine frame I, and attached to the free end of lever 88, is an upwardly tionary 'part of the machine frame, forinstance, i
as is indicated at 50.
From the foregoing, it will be understoodthatv the operation of the narrowing 'headthrough the pawl and ratchet mechanism in the manner here'- inbefore stated will cause the abutment 41 of the sleeves 45 and 46 to advance stepby stepfand thus displace the respective narrowing cornbs`28v and 21 to move in the various directions already.l
. mentioned over a predetermined number of needles, the predetermined number of needles over which the narrowing combs move being determined by the adjustment of thevmechanism, a matter 'well understood by those versed' inthe art. The narrowing combs 26 and 21l are in tended to narrow the .heel fabric at the proper time for shaping the same in the usual manner by forming the narrowing lines N as represented in Figure 1'1.
Sliding movement isirnparted to the transfer combs I3, I4, I5, and I8 by -means of a specially devised control Vwhich may be stated to comprise a, shaft 5I rotatably carried in spaced bearing arms 52 secured upon the fixed shaft 22.
Rigidly mounted upon the intermediate portion of the rotatable shaft 5I is acylindricalmember 53 having its end surfaces 54 recessed out to provide grooves 55 defining rims 55"having camming surfaces 58'- over which wide rollers 5S mounted on plates 51, one plate being connected to the transfer bar I8 carryingthe small transfer comb I5, and the other plate being connected projecting arm 12 disposed to engage an abutment 13 rigid with an arm 14 flxedly-secured to the shaft 5I, At this point, it is to be noted that the arm 14 is normally urged downwardly, for example, by means of a coil spring 15 having one of its ends connected to the abutment 13 and its other end connected to an extension 18 conveniently secured to one of the transfer bar brackets 2l. Because of this feature, and due to the rigid connection between the. arm 14 and the shaft 5I, it will be understood that the latter is constantly urged to rotate in one direction. However, the rotating movement of the shaft 5I and, consequently, the downward movement of the arm 14 are limited, as more clearly shown in-Figures '1 and 8, by means of a stop pin 11 adapted to engage one ofthe bearing arms 52 and carried by y a collar 18 fixed on the shaft 5I.
From the foregoing description of the control and its operating means, it will be appreciated that when the cam 84 isvbrought in operative relation with the roller 85 through the shogging of the main cam shaft 43, the leverl66 will rock causing a vertical reciprocation of th'e 'arm 66.
Due to the cooperative association of :said arm.
86 with the arm 12, the shaft 5I is thereby oscillated, resulting in imparting. an oscillating movement to the cylindrical member 53. This oscillating movement of the cylindrical mamber 53,
to the transfer bar 20 carrying the small transfercomb I6.` The connection between the plates 51 and their respective transfer bars I8 and 20 is preferably adjustable and.' accordingly. said plates may be provided withv elongated slots 58 through whichpass screws 59,- or flike fastening elements. 'I'he adjustability of the plates- 51. is
primarily intended to vary the position of the rollers 56 in relation to-the surface of the cam rims 58 for the purpose to be hereinafter fully t contact with a stop blocks 83 fixed on each of the transfer bars I1 and I9,Acarrying the large transfer combs I3 and I4 respectively'. I
The control just described is intended to be operated automatically and in timed relation with the function of the knitting machine. For this' a cam 84 adapted. when the shaft is moved to its shogged position, to engage a roller 88 rotatably supported upon a rocking lever 88 having one end pivoted to the machine frame, as -shown at of course, displaces the contact point of the sur'- face of the cam rim 56' with the rollers 58, causing the same to move longitudinally of the knitting machine. Thus the osciliatingmovement of the cylindrical member 53 is translated into a reciprocating movement, which reciprocating' movement is transmitted through the plates 51 to the transfer bars I8 and 28 respectively connected thereto, and to the transfer bars I1 and I9 by reason of the stop blocks 63 thereon, which blocks are disposed yin the path` of movement of t the stop 82 carried by the plates 51.
As previously stated, the plates 51 may be adjusted to Vary the position of the rollers 5S in relation to the canming surface of the cam rims 58'. This adjustment is for the purpose of determining the desired number of needles over which the transfer combs III-I5 and Ill-I8 will be moved by the control mechanism. Obviously by setting the rollers 58 nearer to. or further away from. the lowest point of the' camming surface of the cam rims the action of said surface .on the roller 'will be advanced or retarded and, accordingly, cause the initial movement of the transfer action to occur sooner or later during the operative function of the transfer bar control mechanism.
Upon'referring to the diagram shown in Figure 11, the adjustable positioning of the rollers 58 and resulting action of the control member 53 thereon will clearly appear.
v purpose, the main 'cam shaft 43 is provided with Let it be assumed that the curve S repmsents the surface outline of the cam rims 5E' and .is so graduated between the pcint'l? and the point P3 that when the point P3has moved to the level indicated by the dotted lines L-L the transfer 'combs will have moved the distance of three needles, inasmuch as the points PI, P2, and P3 will have successively displaced the roller 56 to the positions IP, 2P, and 3P, each representing the distance between one needle to another. Therefore, if the roller 56 is initially set at the position IP, said roller will start to move from the position IP only when the point PI has reached the level L--L. Likewise, if the roller is initially set at the position 2P, it will remain unaffected until the point P2 has reached the level L-L. It will be understood that the positioning of the roller 56 in relation tothe camming surface of the rims 56' is attained by setting the connection between the plates 51 and their respective transfer bars and by regulating the stops 60 and 8| accordingly.
In practicing the invention, I find it preferable to displace the small transfer combs I5 and I6 for a greater number of needles than the large transfer combs I3 and I4. That this mode of operation may be obtained, the stops 62 are adjusted to rest at a predetermined distance from the associated stop blocks 63 on the transfer bars lI1 and I9 respectively carrying said large transfer combs I3 and I4. The distance indicated by the arrow G between the stops 62 and the stop blocks 63 preferably correspond to the distance of one needle so that the transfer bars I8 and 20 to which the plates 51 are directly connected, will move for a distance corresponding to one needle Withthe initial movement of said plates, whereas the transfer bars I1 and I9 will remain stationary and begin their movement only when the stops 62, during the continued movement of the plates 51, have been brought in contact with the stop blocks 63.
With the plates 51 in inoperative position, the distance G between the stops Gland the stop blocks 63 is maintained by means of an adjustable stop 19 mountedon each transfer bar I1 and I9 and disposed to abut adjacent portions of certain of the transfer rod brackets 2|, the stop 19 being yieldably held thereagainst by springs 80. The distance G referred to is also assured by reason of the fact that the stops 6I carried on the plates 51 are normally urged against the abutting surface by springs 8I.
The machine being adjusted in the manner above defined, it will be understood that the small transfer combs will first move by themselves for a distance of one needle and then the small and large transfer combs will move simultaneously. Thus, as shown in Figure 12, the transfer fingers 82 which represent the transfer fingers carried by the small transfer comb I6 (Figures 1 and 3) are displaced for a distance of three needles, Whereas the transfer fingers 83, representing the transfer fingers carried by the large transfer comb I4, are displaced for a dis.
tance of two needles.
Of course, it is to be understood that by adjusting the stops 62 so that the same will constantly bear upon the stop blocks 63, both the small and large transfer combs will move in unison during the entire transfer operation, and by setting the position of the rollers 56 with respect to camming surface of the cam rims 56' in the manner hereinbefore stated, the transfer combs may be caused to move over a definitenumber of needles, for instance, over two needles or over one needle, as represented in Figures 13 and 14 respectively.
The method of knitting heel fabrics in single unit stocking blanks upon my improved machine is carried out in the following manner:
The full fashioned stocking blank 84, such as own in Figure 16, is of the usual construction, consisting of the welt 85, leg 86, high splice heel 81, instep 88, sole 89, and toe 98, all being knitted continuously on one machine. The blank is adapted to be severed at the points 9i for the insertion of the heel tabs 92 (Figure v17). Subsequent to the severing of the blank 84 at point 9|, the foot portion is folded over the leg portion and the sole sections 89 are folded upon the instep section 88 in the manner more clearly represented in Figure 18 of the drawings. By folding the stocking blank in the manner specifled, it will be appreciated that the marginal row of loops 93 of the high splice heel 81 and the marginal row of loops 94 of each of the sole as indicated at 85, so that said rows of loops 93 and 94 as more clearly shown in Figure 3, may
be topped on or transferred to the needle bar 4 of the footer converted in accordance with the invention to knit the heel tabs.
It is to be noted that because of the folding of the blank, as above set forth, the loops of the foot and sole sections are reversed so that in the topping or transfer operation by the usual means shown at 96 in Figures 1 and 2, the sinker portion of the marginal row of loops 94 of each sole section 89 will engage the corresponding nonknitting needles I2 of the converted footer, whereas the needle portion of the marginal row of loops 93 of the high splice heel section 81 will engage the associated knitting needles I8 and II of said footer in the manner more clearly represented in Figure 3 of the drawings.
The loops 93 and 94 having been thus transferred on the needles of my improved machine, the same is now ready for operation. The carriers are actuated in the well known fashion to lay the yarn or yarns across the knitting needles I0 and II soas to knit the courses 96 of the heel fabric 81. During the knitting of the heel fabric, the loops 94 are gradually transferred for interknitting engagement with said fabric by operation of the transfer mechanism already described.
As stated, the loops 94 on-the non-knitting needles I2 may be transferred the distance of one or more wales, as necessity or preference may dictate. As also stated, in Figure 14 I have illustrated the single wale transfer. According to this mode of operation of knitting the heel tabs and simultaneously joining the sole portions thereto, the transfer fingers 82 and 83 descend through the usual dipping motion of the knitting machine, pick all the loops 94 off the nonknitting needles vI2 and simultaneously transfer said loops one needle distance, which places each end loop successively in engagement with the end knitting needle of the row of needles I0. An intermediate course may be knitted on the needles I8 between each transfer operation to provide the necessary fabric for the -formation' of the heel and to insure sufficient elasticity to the foot. This operation is repeated until all the loops 94 on the non-knitting needles I2 have been transferred the distance of one needle at a time and interknitted to form a seam 91 uniting the sole portions 89 to the heel-tabs 92.
In Figure 13, I have illustrated the two wale Although such openings are not seriously detrip mental to the quality of the fabric, the defect may be overcome by following the method of operation shown in Figure 12. which represents my preferredmode of operation. In practicing this mode of operation, the transfer fingers 82 and 83 are adapted, because of the described adjustment of the mechanism, to simultaneously pick off the loops 94 and while .the points 83 are -moved the distance of two needles, the points 82 are moved the distance of three needles. It will be understood that by proceeding in this manner, the first wale 99 is left without transfer loops. While it is also found preferable to knit three extra courses between each transfer course', the holes which might result thereby are not visible because the connections or joinings are all on the second and third Wale of the heel tabs, said second and third wales usually being tighter than the first wale, which is then free to act as a covering for whatever small holes may appear at the point of juncture between the sole fabrics and the heel fabrics.
The transfer operation causes the marginal loops of the foot fabric to become interlooped with the adjacent marginal loops of the heel tab fabric and, accordingly, no seaming operation is necessary to unite` the same. Further, due to the transfer of the loops in the manner specified, the foot fabric is turned automatically at substantially right angles to the leg fabric, a's shown in Figure 15.
It will be appreciated that while the narrowing combs 26 and 21, and .the transfer combs l3-l4, and |,5-l6 are intended to operate in unison when the narrwings N in the heel fabrics are to be made, the operation of said narrowing combs 26 and 21 may be disrupted without interfering with the proper function of the transfer combs I 3-l4 and l5-I6. This may be accomplished by simply disengaging the dog 31 from its associated ratchet wheel 36 which, of course, will stop the rotation of the spindle 34 and, accordingly, prevent the narrowing function of the nuts 30 and 3| upon said narrowing combs.
Obviously, the invention is capable of several modifications and those modifications which come within the scope of the subjoined claims are to be considered within the spirit of the'invention.
