SPECIFICATION forming part of Letters Patent No. 793,913, dated July L 1905,

Application filed May 26, 1904. Eierial No. 209,857.

Be it known that L MARTIN J. timeou- NnssY, a citizen of the United States, residing at Amsterdam. county of Montgomery, and

State of New York, have invented certain new and useful limprovements in cltitch lh'ansl'erring Mechanism for Knitting-lvlachines, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel eonstruction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several ligures therein.

ltis known in the art that a pattern fabric can be produced upon a knitting-maehine by transferring certain of the loops or stitches from one needle to another as the knitting operation proceeds. This is accomplished by transferring a loop or stitch from one needle to an adjacent needle, leaving both stitches or loops upon the latter needle to be treated as a single stitch in the subsequent steps of the knitting operation and leaving the needle from which the stitch was transferred without a stitch until supplied with yarn from the next feed. The resultant fabric has at intervals two-thread or double loops or stitches and adjacent thereto small holes left by the transferred stitches. By proper arrangement or combination of ordinary knittingwheels o ierating in connection with certain feeds and suitably-constri'1cted stitch-transferring devices operating in connection with certain other feeds it is possible to locate the double stitches and holes at predetermined points in the fabric, and thereby to produce a variety of ornamental patterns.

My invention relates principally to means for transferring stitches from one needle to another in knitting fabric of the nature indicated; and the principal object of my invention is to facilitate the knitting of pattern fabrics on circular knitting machines by means of transferred stitches.

Other objects of the invention will appear in connection with the following description.

My invention applicable to various styles of spring-needle knitting-machines, and in its preferred forln, as shown in the drawings, it especially adapted for use in connection with springneedle circularknitting machines, and particiiilarly that style of circular knittii'ig machine in which the needles are mounted in what is known in the art as a trick-cylinder --that is, a cylinder promanner, which ordinary feed or feeds are not shown in the drawings, as their manner of operation is well understood, only one feed be ing shown which operates in connection with the stitch-transferring mechanism.

In Fig. 1 of the drawings considerable latitude has been taken in the disposition of the various attachments which embody my invention, and they are shown somewhat diagrammatically for clearness of illustration. Referring to said ligu re, 1 is the cylinder, which may be any well-known type of cylinder adapted for spring-needles, a plurality of needles 2 being shown mounted on the cylinder. Located within the cylinder is the usual inner circle or support 3, and beneath the cylinder is the outer circle 1, also known as the feedcircle or stand-bed. Thefeed-stand 5,erected from the stand-bed at, supports the stitch sinker wheel 6, which operates in the usual manner to feed yarn to the needles as the cylinder is rotated. For reasons which will be presently explained I employ a shoe or cam 7 in place of the usual cloth-wheel or pushdown wheel in connection with the stitchsinker wheel 6, which shoe, however, performs the usual function of the cloth-wheel in depressing the edge of the cloth below the beards of the needles while the new stitches are being fed to the needles. After passing the stitch-wheel 6 the needles and stitches are next subjected to the action of an ordinary plain presser 8 and landing-wheel 9, which operate in the usual manner, the presser to close the beards of the needles and the landing-wheel to force the older stitches upwardly toward the ends of the needles outside of the beards thereof preparatory to said older stitches being forced entirely off the needles by means of the cast-off or knocking-over wheel 10. After the older stitches have thus been cast off there are left upon the needles only the stitches formed by the stitch-wheel 6. To secure the transfer from one needle to another of one of said remaining stitches, I provide what I term a gathering-wheel 11, the function of which is to bring into close proximity with each other the needles from which and to which the stitch is to be transferred; an a'lining-wheel 12, the function of which is to bring the two gathered needles into line with each other approximately radially to the needle cylinder, so that the stitch in the outer of the two gathered needles will lie directly over the end of the inner of said gathered needles; a cloth depressor wheel 5, the function of which is to force the edge of the fabric downwardly and with it the loop or stitch on said outer needle, which is to be transferred, downwardly over the end of said inner needle, causing said loop to embrace or inclose both said needles and to hold the cloth and loops or stitches so depressed until they are brought within the influence of the ordinary puslrdown or clothwheel 13, which serves the usual purpose of forcing the cloth and stitches down below the beards of the needles; a cut-presser 1a,

cut to close the beards of only the needles from which the stitches are to be transferred; a landing-wheel 15, operating in connection with said cut-presser to locate the stitch to be transferred outside of and upon the beard of the needle from which it is to be transferred, and a cast-off or knocking-over wheel 16, which casts off from the needles upon which they were originally formed the stitches which have been so landed outside the beards thereof, thereby completing the transfer of the stitches, leaving the needles from which stitches have been transferred free of yarn, while the needles to which stitches have been transferred are provided with double loops or stitches which in the subsequent operation of knitting are treated the same as single stitches. Referring more particularly to the mechanism for causing the loop which is to be transferred to embrace or inclose both the needle upon which it was originally formed and the needle to which it is to be transferred, the gathering-wheel 11 is in the form of a burwheel rotatively mounted in approximately horizontal position upon the bracket 17, fixed upon the inner circle, said wheel being located within the needle-cylinder in position to mesh with the needles thereon and to engage the backs or inner vertical surfaces of the needles as distinguished from the front or beards thereof.

The gathering-wheel, which is shown detached in Fig. 2, is provided in its periphery with radial slots or notches 18, adapted to receive the needles other than those to and from which stitches are transferred, and certain other slots or notches 19, which extend obliquely inwardly and rearwardly, (referring to the direction of rotation of the wheel as indicated by arrows.) Adjacent to each inclined slot 19, and in rear thereof, is a tooth 20, projecting prominently from the general periphery of the wheel, which tooth is provided on its forward side with a needle-en gaging surface 21, inclined inwardly and forwardly toward said slot and intersecting the rear wall of said slot at aslightly-obtuse angle. As the needle-cylinder and gathering-wheel rotate together, the needles other than those to and from which stitches are to be transferred mesh freely with the notched portions 18 of the periphery of the gathering-wheel, while a needle 2, to which a stitch is to be transferred, will freely enter the outer end of an inclined notch 19. The next rearwardlylocated needle 2 however, will be engaged by the inclined surface 21 at a point considerably in rear of a line projected from the center of the needle-cylinder through the center of the gathering-wheel and at such an angle as to force the engaged needle 2" outwardly out of line with the neighboring needles in the cylinder. This is accomplished by springing the needle which is made of re silient material. As the movement of the cylinder and wheel is continued and the needle 2" approaches a point in line with the centers of the cylinder and gathering-wheel, the angle at which the surface 21 engages said needle will be so Cl'lttHgBLl that the elasticity of the sprung needle will cause it to slide over the inclined surface 21 into the notch 19 on the outer side of the needle 2, which had previously entered said notch.

The notch 19 is of a width less than the diameters of two needles, so that the last nee die to enter the slot 19 bears against the outer side of the previously-entered needle. The needle from which and the needle to which the stitch is to be transferred are thus brought into close proximity or contact with each other. .lly the action of the inclined front wall of the slot 19 and the inclined tooth-surface 21 the assen'ibling or gathering together of said two needles is accomplished by a bend.- ing movement of each needle toward the other, so that both are displaced somewhat from their original position. To make more certain a proper alinement of said two needles, so that the loop or stitch on the needle 2 can be made to embrace or inclose also the needle 2, the alining'wheel 12 is provided in the form of a bur-wheel comprising a thin disk, which overlaps slightly the edge of the gathering-wheel in close proximity to the upper surface thereof and is provided in its periphery with a series of notches 23, adapted to receive the needles other than those to and from which stitches are transferred, and with another series of slightly-deeper notches 2 1-, adapted each to receive two gathered needles 2 and 2. The deeper notches 2a are of a width approximately equal to the diameter of a single needle, and the alining-Wheel is so arranged and its notches 2a are so located that said two needles when seated in a notch 2a are exactly in line with each other amin'oximately radially to the needle-cylinder and in such position that the loop or stitch in the outer needle is directly over the end of the inner needle. The alining-wheel is rotatively mounted upon a vibratory arm 36, pivoted at 37 upon a stand or bracket 29, erected from the bed a.

The alining-wheel meshes with and is retated by the needles on the needle'cylinder, and its notches are so arranged that when the parts are operated, as described, the deeper notches 2-1 will at the proper time be in position to receive the gathered needles --that is, the needles in the inclined notches 19 in the gathering-wheel while the notches 23 will be in position to receive, respectively, the neodles intervening between two neighboring groups of gathered needles. While the loop or stitch in the outer needle is thus caused by proper almement of the needles to lie directly over the end of the inner needle, the fabric is engaged by the cloth-depressor wheel and thereby depressed so as to force said loop or stitch down over and inclosing said inner needle, in which position said stitch iucloses both the needle to which and the needle from which it is to be transfm'red.

The cloth depressor wheel is rotatively mounted upon a vibratory arm 36, pivoted at 37 upon a stand or bracket 2%), erected from the bed at. The cloth-derncssor wheel 5, which occupies a vertical position, is yieldingly forced down, by means of the spring 35, against the upper side of the gatl1ering-wl1eel or the interposed fabric and is rotated by frictional contact therewith. The peripheral portion of the cloth-depressor wheel 5 is preferably formed of leather, as by interposing a disk 25 of leather between two washers 26, clamped together by a flanged screw-bushing 2'7 and nut .28, as shown in Fig. 5; but said wheel may be made of other desired material. The cloth-wheel 13 is rotatively mounted upon an arm 30, projecting from the stand or bracket 3i, erected from the bed 4, upon which stand is also rotatively mounted the cut-presser 1st. The arm 30 is shown partly broken away for convenience of illustration. The landing'wheel 9 is rotatively mounted upon the bracket 50, the landing-wheel 15 upon the bracket 52, the cast-olf wheel 16 upon the bracket 53, said brackets being secured in fixed position upon the inner circle 5, and the plain presser 8 is rotatively mounted upon a stand or bracket 32, erected from the bed -1, all in the usual manner. Provision can be made in the various wheel-supports for secur ing desired adjustments in the usual manner.

It will be understood that when the fabric is depressed by the cloth-wheel 13 the stitch to be transferred will be forced down below the board of the needle from which it is to be transferred, and also down over the board of the needle to which it is to be tnmsferred to a position below the same in company with the stitch originally on said latter needle. When said stitches are again forced upwardly by the landing-wheel 15, the stitch to be trans ferred will be caused to pass up outside of and over the board of the needle from which it is to be transferred, due to the closing of said beard by the cut-presser 1 t, and will be subsequently cast off from said needle by the cast-oil wheel 16, while said stitch will pass up under the beard of the needle to which it is to be transferred in company with the stitch originally formed thereon, so as to not be cast off, due to the fact that the cut-presser 1% is adapted to receive said last-mentioned needle without closing the beard thereof.

The pattern to be knitted is determined by the relative number of plain feeds employed in connection with the transfer-feed, by the relative number and arrangement of the radial slots and the inclined slots with the teeth adjacent thereto in the gathering-wheel, the

alining-wheel having the proper number and relative arrangement of deep and shallow notches to correspond therewith, and by the number of needles in the cylinder relatively to the notches in the gathering-wheel. As shown in the drawings, the stitch will be transferred from every fourth needle.

By locating the gatheringwheel within the needle-cylinder and causing it to operate upon the inner side of the needles I am able to utilize the tension of the web of fabric to reinforce. and support the needles which are sprung outwardly out of alinement with the other needles in the cylinder and to assist the elasticity of said disalined needles to restore the alinement of the same when relieved from outward pressure. By locating the gathering- Wheel within the cylinder I am also able to secure a greater interval for operation upon the needles than could be secured by a gathering-wheel on the outer side of the cylinder, due to the fact that the internal location of the wheel permits it to mesh with the cylin' der throughout a greater number of degrees of its periphery. By making the teeth or projections which are located between the teeth 20 of less length or projection from the center of the wheel than said teeth 20 I am able to accommodate my improved gatheringwheel to the interior of a cylinder of comparatively small diameter, using needles of line gage. The internal location of the gathering-wheel is particularly advantageous when employed with a trick-cylinder, as with such a cylinder I am able to reduce the height of the needle-clamping plates, leaving the needles unsupported on the outer side to a considerably greater depth than on the inner side.

As shown in Fig. 9, the needle-clamping plate 40 terminates at its upper end a considerable distance below the upper edge of the cylinder, which supports the shanks of the needles on the inner side, said construction permitting the needles to be sprung outwardly with greater facility and less danger of breaking or permanently bending the neodles than if the needle-plate extended to the full height of the cylinder, while at the same time the support afforded to the needles to resist the inward pull of the web of fabric and inward pressure of the exteriorly-located knitting devices is not materially lessened.

I have shown as integral structures certain of the bur-wheels employed in carrying out my invention; but it will be understood that they can be made in any known manner of making bur-wheels for knitting-machines.

It is desirable to have some or all of the stitches of the course in which is the stitch to be transferred somewhat longer than the stitches in other courses, and the stitch-wheel 6 maybe adjusted to accomplish this result in the usual manner. By so doing, however, an additional strain may be exerted upon the needles by the stitch-wheel and yarn, and I have therefore provided a needle-supporting wheel 42, rotatively mounted upon the arm 48, projecting from the feed-stand 5, which arm projects just above the upper ends of the needles and supports the wheel with its lower portion in close proximity to the inner sides or backs of the needles opposite the stitchwheel. This needle-supporting wheel has a recessed outer face inclosed by an edge flange 44, which is notched to mesh with the needles, the supporting-arm 43 being inwardly and downwardly inclined, so as to cause only the bottom edge of the wheel 42 to engage the needles, such point of engagement being below the beards of the needles a sufficient distance to not interfere with the operation of the stitch-wheel, the blades of which are free to pass between the needles into the recess in the outer face of the needle-supporting wheel. The needles are thus supported to resist the inward thrust of the stitch-wheel and yarn, insuring uniformity in the length of the stitches. By employing a shoe or cam '7 in place of the usual cloth-wheel I am able to make said shoe or cam of hollow or skeleton.

form to receive therewithin said needle-supporting wheel 42, as shown.

In order to secure uniform tension upon the fabric at the point where the transfer of stitches is accomplished, I provide a tensionwheel 45, rotatively mounted upon-an arm 46, projecting from the bracket 17, upon which is mounted the gathering-wheel, said tensionwheel being adapted to engage and force outwardly to the desired degree the web of fabric just above the transferringmechanism. The tension-wheel is rotated by engagement with said web.

It is characteristic of certain features of my invention that the locating of the two needles in proper position for the transfer of a stitch from one to another is accomplished principally by bending or displacing the needle from which the stitch is to be transferred, which bending movement is in opposition to the pull or tension of the fabric, causing the loop or stitch which is to be transferred to be drawn out more or less beyond the other loops and directly over the end of the needle to which said stitch is to be transferred, and that while so drawn out and located said stitch is forced down by a depressing device over the end of the needle to which it is to be transferred and is thereby landed securely thereupon. To accomplish this displacement by means of an outward and sidewise movement of the needle from which the stitch is to be transferred, it will be readily seen that the loop to be transferred is not drawn radially from the fabric, but diagonally or obliquely, so that it is not sufiicient that the displaced needle should be brought into exact radial line with the needle to receive the transferred stitch; but it is necessary that the displaced needle should be moved sufficiently past said teams needles in the cylinder. This is accomplished by springing the needle which is made of re silicnt material. As the movement of the cylinder and wheel is continued and the needle 2" approaches a point in line with the centers of the cylinder and gathering-wheel, the angle at which the surface 21 engages said needle will be so cl'ianged that the elasticity of the sprung needle will cause it to slide over the inclined surface 21 into the notch 19 on the outer side oi the needle 2, which had previously entered said notch.

The notch 19 is of a width less than the diameters two needles, so that the last needle to enter the slot 19 bears against theouter side of the previously-entered needle. The needle from which and the needle to which the stitch is to be transferred are thus brought into close proximity or contact with each other. By the action 01 the inclined front wall of the slot 19 and the inclined tooth-surface 21 the assembling or gathering together 01 said two needles is accomplished by a bending movement of each needle toward the other, so that both are displaced somewhat from their original position. To make more certain a proper alinernent of said two needles, so that the loop or stitch on the needle 2" can be made to embrace or inclose also the needle 2, the alining-wheel 12 is provided in the form of a bur-wheel comprising a thin disk, which overlaps slightly the edge of the gathering-wheel in close proximity to the upper surface thereof and is provided in its periphery with a series of notches 23, adapted to receive the needles other than those to and from which stitches are transferred, and with another series of slightly-deeper notches 2%, adapted each to receive two gathered needles 2 and 2". The deeper notches 2a are of a width approximately equal to the diameter of a single needle, and the alining-wheel is so arranged and its notches 2 1 are so located that said two needles when seated in a notch 2 1 are exactly in line with each other approximately radially to the needle-cylinder and in such position that the loop or stitch in the outer needle is directly over the end of the inner needle. The alining-whcel is rotatively mounted upon a vibratory arm 56, pivoted at 37 upon a stand or bracket 29, erected from the bed a.

The alining-wheel meshes with and is re tated by the needles on the nccdle-cylinder, and its notches are so arranged that when the parts are operated, as described, the deeper notches M will at the proper time be in position to receive the gathered needles that is, the needles in the inclined notches .19 in the gathering whecl -while the notches 9.3 will be in position to receive, respectivel v, the needles intervening between two neighboring groups of gathered ltieedles. While the loop or stitch in the outer needle is thus caused by proper ahnement ol:' the needles to lie directly over the end 01 the inner needle, the fabric is engaged by the cloth-depressor wheel 5, and thereby depressed so as to force said loop or stitch down over and inclosing said inner needie, in which position said stitch inc-loses both the needle to which and the needle from which it is to be transferred.

The cloth depressor wheel is rotatively mounted upon a vibratory arm 36, pivoted at 37 upon a stand or bracket 29, erected from the bed 1. The cloth-depressor wheel 5, which occupies a vertical position, is yieldingly forced down, by means of the s ning 35, against the upper side of the gathering-wheel or the interposed fabric and is rotated by trictional contact therewith. The peripheral portion of the cloth-demesso r wheel is preferably formed of leather, as by interposing a disk 25 of leather between two washers 26, clamped together by a flanged screw-bushing 27 and nut 28, as shown in Fig. 5; but said wheel may be made of other desired material The cloth-wheel 13 is rotatively mounted upon an arm 30, projecting from the stand or bracket 31, erected from the bed 1, upon which stand is also rotatively mounted the eutqn'esser 1 1. The arm 30 is shown partly broken away for convenience of illustration. The landing-wheel i) is rotatively mounted upon the bracket 50, the landing-wheel 15 upon the bracket 52, the east-oil? wheel 15 upon the bracket 53, said brackets being secured in fixed position upon the inner circle 3, and the plain presser 8 is rotatively mounted upon a stand or bracket 23%, erected from the bed -1-, all in the usual manner. Provision can be made in the various wheel-supports for secnring desired adjustments in the usual manner.

It will be understood that when the fabric is depressed by the cloth-wheel 13 the stitch to be transferred will be forced down below the board 01'' the needle from which it is to be trz'ms'lerred, and also down over the board of the needle to which it IS to be transferred to .a position below the same in company with the stitch originally on said latter needle. \Vhen said stitches are again forced upwardly by the landing-wheel 15, the stitch to be trans-- terred will be caused to pass up outside 01 and over the beard oi the needle from which it is to be transferred, due to the closing oli said board by the cut-prcsser 11, and will be subsequently cast oil from said needle by the cast-off wheel 16, while said stitch will pass up under the heard 01 the needle to which it is to be transferred in company with the stitch originally formed thereon, so as to not be cast on, d no to the fact that the cut'presser 14: is adapted to receive said last-mentioned needle without closing the beard thereof.

The pattern to be knitted is determined by the relative nui'nber of plain feeds employed in connection with the transfer-teed, by the relative number and arrangen'ient ot' the radial slots and the inclined slots with the teeth adjacent thereto in the gathering-Wheel, the

alining-whecl having the proper number and relative arrangement of deep and shallow notches to correspond therewith, and by the number of needles in the cylinder relatively to the notches in the gathering-wheel. As shown in the drawings, the stitch will be transferred from every fourth needle.

By locating the gatheringwheel within the needle-cylinder and causing it to operate upon the inner side of the needles I am able to utilize the tension of the web of fabric to reinforce and support the needles which are sprung outwardly out of alinement with the other needles in the cylinder and to assist the elasticity of said disalined needles to restore the alinement of the same when relieved from outward pressure. By locating the gatheringwheel within the cylinder I am also able to secure a greater interval for operation upon the needles than could be secured by a gathering-wheel on the outer side of the cylinder, due to the fact that the internal location of the wheel permits it to mesh with the cylinder throughout a greater number of degrees of its periphery. By making the teeth or projections which are located between the teeth 20 of less length or projection from the center of the wheel than said teeth 20 I am able to accommodate my improved gatheringwheel to the interior of a cylinder of comparatively small diameter, using needles of line gage. The internal location of the gathering-wheel is particularly advantageous when employed with a trick-cylinder, as with such a cylinder I am able to reduce the height of the needle-clamping plates, leaving the needles unsupported on the outer side to a considerably greater depth than on the inner side.

As shown in Fig. 9, the needle-clamping plate a0 terminates at its upper end a considerable distance below the upper edge of the cylinder, which supports the shanks of the needles on the inner side, said construction permitting the needles to be sprung outwardly with greater facility and less danger of breaking or permanently bending the needles than if the needle-plate extended to the full height of the cylinder, while at the same time the support afforded to the needles to resist the inward pull of the web of fabric and inward pressure of the exteriorly-located knitting devices is not materially lessened.

I have shown as integral structures certain of the bur-wheels employed in carrying out my invention; but it will be understood that they can be made in any known manner of making bur-wheels for knitting-machines.

It is desirable to have some or all of the stitches of the course in which is the stitch to be transferred somewhat longer than the stitches in other courses, and the stitch-wheel 6 may be adjusted to accomplish this result in the usual manner. By so doing, however, an additional strain may be exerted upon the needles by the stitch-wheel and yarn, and I have therefore provided a needle-supporting wheel 42, rotatively mounted upon the arm 43, projecting from the feed-stand 5, which arm projects just above the upper ends of the needles and supports the wheel with its lower portion in close proximity to the inner sides or backs of the needles opposite the stitchwheel. This needle-supporting wheel has a recessed outer face inclosed by an edge flange 44, which is notched to mesh with the needles, the supporting-arm 43 being inwardly and downwardly inclined, so as to cause only the bottom edge of the wheel I2 to engage the needles, such point of engagement being below the beards of the needles a sufiicient distance to not interfere with the operation of the stitch-wheel, the blades of which are free to pass between the needles into the recess in the outer face of the needle-supporting wheel. The needles are thus supported to resist the inward thrust of the stitch-wheel and yarn, insuring uniformity in the length of the stitches. By employing a shoe or cam 7 in place of the usual cloth-wheel I am able to make said shoe or cam of hollow or skeleton form to receive therewithin said needlesupporting wheel 42, as shown.

In order to secure uniform tension upon the fabric at the point where the transfer of stitchesis accomplished, I provide a tensionwheel &5, rotatively mounted upon an arm 4:6, projecting from the bracket 1'7, upon which is mounted the gathering-wheel, said tensionwheel being adapted to engage and force outwardly to the desired degree the web of fabric just above the transferring mechanism. The tension-wheel is rotated by engagement with said web.

It is characteristic of certain features of my invention that the locating of the two needles in proper position for the transfer ofa stitch from one to another is accomplished principally by bending or displacing the needle from which the stitch is to be transferred, which bending movement is in opposition to the pull or tension of the fabric, causing the loop or stitch which is to be transferred to be drawn out more or less beyond the other loops and directly over the end of the needle to which said stitch is to be transferred, and that while so drawn out and located said stitch is forced down by a depressing device over the end of the needle to which it is to be transferred and is thereby landed securely thereupon. To accomplish this displacement by means of an outward and sidewise movement of the needle from which the stitch is to be transferred, it will be readily seen that the loop to be transferred is not drawn radially from the fabric, but diagonally or obliquely, so that it is not sufficient that the displaced needle should bebrought into exact radial line with the needle to receive the transferred stitch; but it is necessary that the displaced needle should be moved sufficiently past said radial line to bring the two needles referred to into line with the loop-aperture in order to locate said loop fully over and upon the needle which is to receive it. it will thus be seen that while the gathered needles are alined approximately radially to the cylinder they are not exactly so, but are in a line extending somewhat obliquely rearwardly of the axis of the cylinder with reference to the direction in which the cylinder rotated. This oblique alining of the needles is shown in Fig. 11 and is accomplished by reason of the inclination of the slots 19 in the gathering-wheel, which slots are of a width adapted to receive a single needle, but of a depth adapted to receive two needles.

The deeper notches in the aiming-wheel while radial to said wheel are made to correspond with the proper oblique arrangement of the gathered needles by locating said aliningwheel slightly in advance of a line passing through the centers of the cylinder and gathering-wheehthe relative positions being substantially shown in Figs. 1 and 3.

For certain purposes of the invention the alining-wheel may be omitted.
