Manually Operated Knitting Machine Patents (Class 66/60H)
  • Patent number: 5058400
    Abstract: An Intarsia carriage for a knitting machine incorporates an integral row counter operable by a spring plunger on the counter engaging a cam on the bed of the knitting machine. The counter has three drums 20, 21 and 22 controlled by ratchets, the drums having internal teeth. Each drum 20, 21 and 22 is carried on a hollow sleeve 29 supported on a segment 30 engaged on a main shaft 17. Three staggered spring click levers 34, 35 and 36 engage internal teeth 27 in the drums and each drum has an internal recess which allows the click lever to move outwardly for one tooth only after nine clicks this causes the adjacent click lever to move its drum one click.

  • Patent number: 5014524
    Abstract: A flat bed knitting machine having plural carriages that are independently controllable, preferably both as to movement along a needle bed and as to the knitting task performed thereby. A separate driver is provided for each of the carriages to move the carriages independently and reciprocally along the needle bed. A preferred embodiment includes a device for preventing the carriages from interfering with one another as they are moved along the needle bed.

  • Patent number: 4557119
    Abstract: A carriage for a hand-operated knitting machine is disclosed which is suitable for knitting with a thick or heavy yarn. A brush wheel is supported on a support plate for rotation substantially in a vertical or acutely inclined plane and extends at a lower end thereof between a sinker and a forward edge of a needle bed and below a lower face of a knitting needle in the needle bed so that it may push down loops suspended from the knitting needles.

  • Patent number: 4542632
    Abstract: A pair of flat needle beds are disposed in a V-configuration on a frame. Each needle bed includes a plurality of needles which can be extended and retracted by manually grasping butts thereof. When the needles of both beds are extended, a generally V-shaped recess is defined therebetween along which a yarn to be knitted is laid by hand. For single knitting, one of the flat needle beds can be omitted and an attachment can be secured to the frame which has a plurality of fingers which co-operate with the needles in the remaining bed.

  • Patent number: 4414827
    Abstract: A collapsible flat bed knitting machine has a foldable needle bed having a multiplicity of sinker elements and latch needles. The needle bed is divided along its length three parts which we foldably connected together at the mutually opposite longitudinal end portions by improved connector units. Each of the connector units has a vertical axis which is disposed near the front edges of the sinker elements disposed at the end portions. One of the two mutually connected contiguous needle bed parts may be swung relative to the other needle bed part in a horizontal plane with the vertical axis as center and brought to the collapsed position in which the sinker elements of the needle bed parts are directly opposite to one another.

  • Patent number: 4413487
    Abstract: Each of a plurality of sinker elements on a needle bed having a plurality of knitting needles of a hand-operated knitting machine has a vertically extending, endwise open slot formed at its forward end. For casting on, an end segment of a knitting yarn is successively passed through the respective slots of the sinker elements to twist the end segment with another segment of the yarn forming a first row. Needle loops in the first row are drawn from between the twisted yarn segments, thereby providing a knit article with a closed edge which will not be loosened by a pull at the edge of the article.

  • Patent number: 4400952
    Abstract: A stitch transfer device for a V-bed knitting machine, for transferring stitches from needles 4 in a first needle bed to needles 2 in a second needle bed comprises a carrier 5 slidably mounted on the second needle bed, a stitch transfer element 11 being mounted on carrier 5 for vertical and back and forth reciprocating movement. By means of interconnected cams, operable by rotation of a handle 21 on carrier 5 and cam follower and lever mechanisms cooperating with said cams, the stitch transfer device is moved up and down and back and forth, and the respective needles 2 of the second bed moved back and forth longitudinally, in a predetermined sequence which produces, reliably, one desired stitch transfer per revolution of the handle 10.The device affords high reliability of stitch transfer in a mechanical fashion, with a substantial reduction in time and labor, in operation, as compared with stitch transfer by means of hand held tools.

  • Patent number: 4392364
    Abstract: A flat bed knitting machine comprising a flat elongate bed on which is retained a plurality of parallel, latchable, needles equally spaced along the length of the bed and each movable relative to the bed in a direction lengthwise of the needles and transverse of the bed length, a carriage slidably mounted on the bed for movement transversely of the needles, and a needle-engaging cam plate releasably located in a recess in an upper surface of the carriage and retained in the recess, the carriage having a handle gripped by the user of the machine to transverse the carriage back and forth along the length of the bed.

  • Patent number: 4358938
    Abstract: A loop transfer device including a carriage supported by transverse sliding movement on first and second needle beds on each of which are disposed a multiplicity of latch needles is disclosed. A first path is formed on the carriage for guiding the butts of the loop transferring latch needles on the first needle bed therein and moving such latch needles in a direction perpendicular to the longitudinal direction of the first needle bed. A second path is formed on the carriage for guiding the butts of the loop receiving latch needles on the second needle bed therein and moving such latch needles in a direction perpendicular to the longitudinal direction of the second needle bed.

  • Patent number: 4327564
    Abstract: A collapsible flat bed knitting machine having a foldable needle bed and a carrying case for receiving therein the folded needle bed and other instrumentalities of the machine to facilitate transportation of the machine as of a portable sewing machine. Three parts or sections constituting the needle bed are foldably connected by an improved connector assembly having three plate members fixed respectively to the bed parts. The assembly connects the bed parts in their assembled position in sufficiently exact alignment to assure smooth traverse of a carriage on the thus completed needle bed.

  • Patent number: 4238937
    Abstract: A fabric manipulating device for use with a knitting machine of the type having a flat needle bed containing a plurality of equi-spaced knitting needles tricked into the bed includes a carrier that is mounted on the bed for sliding, needle-by-needle movement along the bed to effect loop manipulation. A cam-controlled linking needle is mounted on the carrier in the plane of the knitting needle in opposing relationship thereto for movement to and from the knitting needles to effect the intended knitted loop linking manipulation. A cam-controlled positioning member and loop restricting member, operating in timed relationship with a cam-controlled loop expanding mechanism and stationary loop contacting surfaces, orients and expands a knitted loop retained on the stem of a knitting needle opposing the linking needle to permit the linking needle to enter the expanded loop while a cam-controlled actuator causes the knitting needle to knock-over the loop onto the linking needle.
