9 Claims,

This invention relates to a knitting machine and more especially to a wrap stripe attachment therefor.

It is an object of this invention to provide wrap stripe means associated with a circular knitting machine and having means for passing the wrap threads across the needle circle and back behind the needles after certain raised needles have engaged the wrap threads, thus wrapping the wrap threads around the needles during knitting, and providing a horn secured atone end to a bracket secured to the latch ring of the knitting machine and along which the wrap threads travel and pass ofi the other end of same when the needles carrying the wrap threads approach the knitting wave.

It is another object of this invention to provide in a knitting machine, a wrap stripe attachment for passing wrap threads across the needle circle and back into the inside of the needle circle so that certain raised needles will engage the wrap threads, and the wrap threads will thus be wrapped around the needles and also means are provided for raising selected needles to take the wrap threads comprising a cam adapted to be moved towards and away from the needle circle with certain of the needles having associated .therewith along butt jacks, other needles which are adapted to take the wrap threads having associated therewith medium butt jacks and the other needles which do not take the wrap threads and which do conventional knitting, having short butts thereon. In this machine, only every other needle throughout the needle circle has a jack associated therewith. Means are provided, including a raising cam controlled by the pattern drum, which when advanced fully towards the needle circle, engages the long butt and medium butt jacks, and raises selected spaced needles to take the wrap threads for the entire travel of the needle circle; that is, to form wrap stripes at spaced intervals entirely around the stocking. During heel and toe knitting, it is, of course, evident that the wrap stripes should not extend through the heel and the sole of the stocking. The medium butt jacks are provided for controlling the needles on one-half of the needle circle, so that when the raising cam is moved to midway or intermediate position, it will not raise 2 raised needles to engage the wrap threads to" form wrap stripes in the fabric being knitted and having an arcuate horn shaped member along which the wrap threads travel until they almost reach the knitting wave from whence the wrap threads pass off of the end of the horn, said horn being attached to the bracket which holds the clamp and cutter plate and extending downwardly and then extending in an arc of a circleimmediately inside the needles, said machine having a clamp and cutter plate associated therewith having a guide finger on one end which extends upwardly and over the end of the horn from whence the wrap threads pass in a knitting operation and the other end of the clamp and. cutter plate extending below and in spaced relation to the horn but extending to theouter edge of the horn, so that during reciprocatory knitting, the wrap threads cannot-pass above the clamp and cutter plate but on account of the pointed end of the clamp' and cutter plate passing beneath the horn a substantial distance, it will cause the wrap threads guided by the horn, during back and forth knitting, to be confined by the horn and clamp and cutter plate, and will not pass on top of the clamp and cutter plate.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is an elevation of the upper portion of a knitting machine commonly termed a Scott and Williams B-5 machine and showing the wrap stripe attachment mounted thereon;

Referring more specifically to the drawings, the numeral l indicates the bed plate of a knitting machine having the tubular portion H extending downwardly therefrom. The bed plate is an annular member and has mounted for rotation therein a needle cylinder having a plurality of needles mounted in vertically disposed grooves therein. This cylinder is driven by conventional means such as a bevelled gear l3 located on the main shaft l4 and meshing with a horizontally disposed bevelled gear, not shown, afiixed to the cylinder. The main shaft |4 also has a bevelled gear l6 mounted thereon which meshes with a bevelled gear H on a shaft "3 which projects upwardly and drives the wrap stripe mechanism which will be presently described.

In the drawings we have shown certain spaced needles |3| which have medium butt jacks M associated therewith and certain other spaced needles |3| having long butt jacks L associated therewith and the remainder of the needles |3| have short butt jacks S associated therewith. Of course, in this type of machine only every other one of the needles will have a jack associated therewith as the other needles I36 will have their conventional butts which will be raised and lowered in a conventional manner by conventiona1 cams. The purpose of these different length jacks will be explained later in this application.

The knitting machine has a conventional sinker ring associated therewith having conventional sinkers, not shown, mounted therein and which project between the needles in a conventional manner for holding the loops on the needles and preventing the loops being raised by the needles. The machine also has a conventional latch ring 2| pivoted as at 22, and it also has a plurality of yarn feed fingers 23 which operate in a conventional manner. Mounted within the latch ring is a gap closer ring 24 which is oscillatable by means of a link 26 having its other end connected to a lever 21 which is operated in a conventional manner by the main pattern drum. The gap closer ring is held in nornial operating position so as not to close the throat gap during circular knitting by means of a tension spring 36 anchored at one end to the lever 21 and at its other end to a spring perch :1

3| secured to the exterior of the latch ring.

The latch ring has a projecting portion 33 which is adapted to engage a leaf spring 34 mounted on a bracket 35 extending upwardly from the bed plate II] for holding the latch ring in lowered or operating position.

The latch ring has secured thereto a bracket which is secured to the projecting portion 33- of the latch ring and extends upwardly and then inwardly to a point about centrally of the needle circle and has secured to the lower surface thereof centrally of the needle circle by means of a shaft 39 a clamp and cutter plate 4| which has a conventional spring clamp 42 and a pivoted clamp 43 and a cutter mechanism 44 which are conventional and are operated by a link 45 having its upper end pivoted to a lever 41 pivoted on a shaft 48 and is operated by a conventional push rod engaging the outer end thereof and which push rod is not shown but is controlled by the main pattern drum.

The lever 41 has projecting upwardly therefrom an arm 5| which is adapted to engage the horizontal portion of an arm 52 having its lower 'end secured as at 53 in a crank member 54 pivoted as at 55 and having a cam portion 56 on its free end adapted to be engaged by a cam on a disk on the wrap stripe shaft which will be presently described to operate the clamp and cutter upon each revolution of the wrap shaft.

The bracket member 4|] also has extending downwardly therefrom a shaft 60 which is secured also to the clamp and cutter plate 4| for assisting in supporting the clamp and cutter plate. The bracket 46 centrally of the clamp and cutter plate rises upwardly and then laterally, and has a bearing portion 64 associated therewith in which a bushing 65 is. rotatably mounted. This bushing 65 has an enlarged portion 66 secured on its upper end which is adapted to rest on top of the bearing 64. The bushing 65 has a plurality of Vertically disposed bores 61 therein through which the wrap threads W pass on their travel from the yarn packages 98 to the needles.

Integral with the lower end of the bushing 65 is a bevelled gear 1a through which the bores 61 extend. The wrap shaft 12 has a key 13 therein and the bushing 65 has a key-way 14 therein which allows up and down movement of the wrap shaft 12. The bevelled gear H! has meshing therewith a bevelled gear 15 which is mounted on a shaft 18 rotatably mounted in'a portion 16 of the bracket 40 and this portion 16 extends downwardly and is secured to a projecting portion of the latch ring as at 11.

Secured on the shaft 18 is another bevelled gear which meshes with a bevelled gear 8| secured on the upper end of the shaft IS. The shaft I8 is mounted in a tubular uprising member 84 and in which it rotates. The outer end of the shaft 18 is rotatably mounted in a bearing portion 86 which is integral with the horizontally disposed portion 83 of the bracket 40. An ou wardly projecting portion 88 of the uprising tubular member 84 has mounted therein a set screw 89 which engages the lower surface of the portion 86 and limits the downward movement of the bracket and the latch ring when they are moved to operating position. The portion 86 has a leaf spring member 90 mounted thereon which projects downwardly and has a suitable hole therein adapted to engage a pin 9| on the outwardly projecting portion 88 to assist the leaf spring 34 in looking the latch ring in operating position.

The downward movement of the wrap shaft 12 is limited by a collar 94 secured on the wrap shaft immediately above the flange 66 by any suitable means such as set screw 95. The wrap shaft '52 has mounted thereon a circular table 96 on which a plurality of pins 9'! are mounted for holding cops of wrap yarn 96. This disk or table has in its hub portion 93 a plurality of vertically disposed eyelets 99 through which the wrap threads W pass.

On the upper end of the wrap shaft i2 is mounted a plate I66 having a plurality of arms l6! and each arm having an eyelet I92 therein through which a wrap thread passes upwardly and goes through a suitable tension device m3 mounted on an uprising portion Hi4 and on the upper end of portions 59-; are mounted the takeup arms H35 through which the wrap yarns also pass, said take-up arms being biased towards upraised position by means of a tension spring 56?. The hub portion 169 of the plate Hi6 has a plurality of vertically disposed eyelets through which the wrap threads pass in their downward movement. Before they pass through these 2,451, are

eyelets, however, they ass beneath a ring 1 I18 supported just outside of the hub portion 1-109 of the: plate i100.

Mounted on wrap shaft 1:2 and below the bearing 64 is a disk IIII having a plurality of vertically disposed passageways ;I;I.I- therein through which the wrap threads :pass in their downward travel to the needles; This'disk ,I I has a cam H 2 thereon adapted to engage .the pointed end 55 of the lever 54 for operating the clamp and cutter mechanism upon each revolution of the wrap shaft when the wrap shaft is in lowered position.

Immediately below the disk Ill] and on the lower endof the wrap shaft 12 is a wrap disk Ii 5 having a plurality of vertically disposed tubes IZIfi therein through which the wrap threads W pass in their downward travel and said tubes being adapted to move across the needle circle, since the wrap shaft 12 is mounted eccentrically with respect to the center of the needle circle, but its vertical .aXis is at a point within the needle circle.

Pivoted on shaft 48 is a lever II4 whose front end extends below the disk H0 and its rear end has a pin II 1 engaged by a lever I I8, pivoted at H9 and whose rear end is raised and lowered by -a conventional push rod I23 controlled by the main pattern drum. Mounted on the bracket 45 by means of screws 18-0 is a shank portion I20 of'a substantially semi-circular horn I2I which extends around inside the needle circle in close proximity to the needles to a point immediately past the throat gap of the machine. This horn is disposed slightly above the clamp and cutter plate, but the clamp and cutter plate has a pointed portion I24 which extends to approximately flush with the outer surface of the horn but is disposed below and in spaced relation to the horn Figure 5 and thus prevents the wrap threads from getting above the clamp and cutter plate during reciprocatory knitting. The clamp and cutter plate 41 has a guide 46 extending upwardly and above the horn I2I for guiding the wrap yarns under the clamp and cutter plate. Plate 4! has an upturned finger .9 projecting above the end of horn I 21 to guide the Wrap yarns beneath the clamp and cutter plate 41. The guide finger 46 as well as clamp 42 are secured to the clamp and. cutterplate 4| by means of a screw 49.

It is understood that this machine is usually equipped with a conventional rubber feed attachment for feeding an elastic yarn to the needles especially during the knitting of the top section, but such rubber attachment is not shown for sake of clearness.

In Figure 7 an exploded view of the needle circle is shown looking from the inside thereof and, although not as many needles are present :not have any jacksassociated therewith but whose butts can be long, short or medium, and are controlled by conventional cams, not shown. Alternately disposed between these conventional needles having no jacks associated therewith, are a plurality of'needles I3I. Some of these nee- ;dles I31 have long butts jacks L associated therewith while others of the needles have medium butt jacks M associated therewith. These long and medium butt jacks are adapted to be engaged by a raising .cam I for raising the long butt jacks L and the medium butt jacks M.

The cam I35 has aflixed thereto a stem I31 which is slidably mounted, in a bracket I38- mounted on top of the bed plate II] of the machine. The bracket I38 has a slot I40 on its upper side and a pin MI is aflixed to the shank I31 and has a tension spring I42 secured thereto whose other end is secured to a spring perch I43 secured on top of the bed plate ID. This normally tends to hold the cam I35 out of the path of either the long or medium butt jacks L and M. Adapted to engage the outer end of the portion I31 is a set screw I45 mounted in an upturned portion I 46 on the end of a lever I41 pivoted as at I48 and supported at its other end by a guide I53 disposed thereabove to assist the lever I41 in withstanding the upward thrust of a push rod I52 which is raised by the conventional main pattern drum of the machine.

The push rod I52 has a cut-away portion E69 which is adapted to coincide with lever I41 when the push rod I52 is not resting on any cams on the main pattern drum. This push rod E52 also has a cammed surface I62, which when the push rod I52 is raised upwardly by a low cam on the main pattern drum, causes the lever I41 to be oscillated to advance the cam I35 inwardly to the point where it will engage the long butt jacks L only to raise those groups of needles associated therewith for taking the wrap threads. This position is maintained during the knitting of the heel and during the knitting of the foot out to the toe portion and this prevents any wrap stripes from being formed in the heel and sole portion of the stocking.

When the push rod I52 has ridden onto a high cam on the main pattern drum, it will cause a cammed portion I64 to engage the lever I41 and advance the cam I35 inwardly to its greatest extent which will cause it to engage not only the long butt jacks L but also the medium butt jacks M to raise both the long and medium butt jacks which. will cause the wrap stripe needles all the way around the needle circle to be raised to form wrap stripes not only in the front portion of the stocking but also in the back portion of the leg of the stocking.

In order to traverse the needle circle with the tubes IIS, it is desirable to cut away a portion of the latch ring to form a cavity at I16. There is, of course, danger of needle latches becoming opened and, if they fell into this cavity during knitting, they might be broken unless some provision were made to prevent such. We find it is not necessary to close this cavity I 19 in the latch ring but in the gap closer ring, we cut away certain portions thereof leaving a portion I1I with cammed surfaces I12 and I13 on opposed edges thereof, which will engage any needle latches which might fall to open position while passing the cavity I10. We also cut away all of the vertical portion of the gap closer ring extending from the cammed surfaces I13 over to a cammed surface I15. These cammed surfaces serve to open or close the partially opened latches of any needles which pass thereby.

By this arrangement it is possible to cut what ever size of cavity as'may be necessary in the latch ring, and it is not necessary to close this cavity because the cam surfaces I12, I13, and I15 insure that the needle latch will be moved to 7 fully opened or fully closed position if they should be partially opened in passing by t is cavity I10.

In the drawings and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims,
