Definitions

  • Figure 1 shows an elevation of the machine in the direction of the arrow B shown in Figure 3;
  • Figure 2 shows a plan view of the machine
  • Figure 3 shows the machine fastened to an ordinary table during beating up, in side elevation
  • Figure 4 shows a view of one of the guide sleeves in the direction of the arrow C;
  • Figure 6 shows a diagram of the principles of stitch formation in the machine according to the present invention.
  • Figure 7 shows a partial view of a needle bed with some needles in the non-operative position
  • Figure 8 shows a view of the needle bed with some needles in their uppermost position, into which the needles are pushed in operation and in which the feet lie against the upper guide bar;
  • Figure 10 shows a view of the look from below
  • Figure 14 shows a partial section through the lock, along the line -1212 in Figure 10.
  • the apparatus illustrated in Figure 1 consists of the needle bed 38 ( Figure '13), which is composed of several parts 1 to 4 which are preferably made of synthetic resin plastic and are screwed on to a wooden board 9 of the width E, these parts closely touching one another at the side 1', 4.
  • the needle bed 38 ( Figure '13)
  • parts 1 to 4 which are preferably made of synthetic resin plastic and are screwed on to a wooden board 9 of the width E, these parts closely touching one another at the side 1', 4.
  • they 3 are provided with impressed grooves 5', 6, into which the lock guide strips 5, 6 are let in.
  • On both sides of the needle bed there are two angle-pieces 7, 8 of sheet metal, which at the top are screwed to the lock guide strips 5, 6 and at the side to the wooden board 9.
  • the needles 23 are in the basic position, that is to say out of operation; in this position the needle feet 27 lie against the bottom guide bar 23.
  • the lock (not illustrated in the drawing) is assumed to be located at the right end of the needle bed.
  • the yarn 39 is then inserted by hand from left to right into the channel forming from the two rows of books, the yarn being unwound from any desired ball.
  • the yarn is inserted in such a way that the free end of the yarn projects a certain distance beyond the left edge of the row of needles.
  • the ball can be mounted in any desired position near the hand knitting apparatus.
  • the lock is then moved from left to right along the guide bars by means of the right hand, while the left hand continues to hold the beating-up comb. In the insertion of the yarn care must be taken that when holding by means of the fingers of the left hand the tension applied to the yarn is not too great, since otherwise loop forming is not possible, the lock being blocked.
  • the needles are lowered one after the other by the needle sinker 40 and the yarn is placed in loops over the knockover bite 20 of the needle bed.
  • the needle feet 27 pass through the various positions, starting from the right, as far as the lowest point 27" as shown in Figure 10. From then on the feet pass through the positions 27" shown in chain-dotted lines, because the corresponding needle raiser 33 is disconnected.
  • the cycle then begins again from the beginning, the yarn being inserted by hand and the lock guide from left to right over the needle bed. There are therefore no further idle courses: on the contrary, the thread is placed transversely over the row of needles following each movement of the lock. There is practically no loss of time at all in the reciprocating movements of the lock, as a result of this insertion.
  • the spring 46 then rocks the catch 46 back on to the needle raiser 34.
  • the needle feet are then lowered by the needle sinker 40, moved past the position 27", and then lifted by the left-hand needle raiser 33 until they slide up along the right-hand side of the inclined surfaces 48 of the left-hand catch and then strike against the inclined surface of the left-hand auxiliary needle sinker 43 and are moved inwards by the latter, until finally they reach the position 27.
  • the operation is similar on the return movement of the lock.
  • the needle sinker 40 is disposed to be slidable perpendicularly to the direction of the needle bed within a slot 52.
  • the slot 52 is provided in the housing plate 53 of the lock.
  • the needle sinker 40 is screwed to aguide piece 54 which has two lateral recesses 55, so that this guide piece engages with a central bridge 56 into the slot 52, thus ensuring parallel guiding.
  • a milled nut 57' and a tension plate 57 the needle sinker can be fixed in the various positions.
  • the tension plate 57 is provided with a pointer 58, which moves in front of an adjusting scale 58 ( Figure 1).
  • a straight hand knitting machine comprising a needle bed, a series of needles arranged in slots provided in the needle bed, and a lock assembly movable transversely of the longitudinal direction of the needle bed, such lock assembly including a support, a central needle -7 sinker fixed on the support, a needle lifter on said support on either side of the sinker movable to an inoperative position, an auxiliary needle sinker carried by the support on either side of the needle sinker and spaced from each of said needle lifters, and a bevelled catch swingably mounted on the support in the hiatus between each needle lifter and each auxiliary needle sinker so that when the needle lifters are in an operative position, the needle feet, during successive lock motions, alternately slide on the one hand over one catch, the hooks of the needles being moved into their position projecting furtherest from the needle bed and the needle feet on the other hand sliding beneath the other catch while they lift the catch, the needles not being moved beyond the insertion position.
  • each of said needle lifters is connected to the support by a bolt extending transversely of the support and movable axially of the support, each needle lifter being secured to one end of the bolt and an operating knob attached to the other end of the bolt.
  • a machine as defined in and claimed by claim 2 further characterized in that spring means is operatively connected to each catch urging each of the said catches into engagement with its associated needle lifter.
  • a machine as defined in and claimed by claim 2 further characterized in that the bevel face on each catch is so located as to extend in the direction of their associated needle lifters, with the catches in the closed position.
  • a machine as, defined in and claimed by claim 2 further characterized in that means is provided at the front side of the needle bed to hold down the goods during knitting, such means including two guide sleeves supported below the bed, one sleeve being at one end of the bed while the other sleeve is at the opposite end of the bed, a retaining member extending longitudinally of the bed at the front end thereof and a angular extension at each end of the member lodged in each of the sleeves, the arrangement being such that no obstructions exist during the knitting and turning over of several meshes from the coordinated needles to adjacent needles for pattern formation.
  • a machine as defined in and claimed by claim 2 further characterized in that said catches include inclined faces extending at an angle to the lock guiding direction serving as guiding and abutting surfaces for the needles, trunnions on the support on which the catches are swingably mounted, spring means associated with the catches to cause the catches to abut with their inclined faces on a corresponding upper guide surface of the respective needle lifter, and the catches being so arranged on the support that the inclined faces define immediate continuations of the needle lifter guide edges moving the needle feet.
