Definitions

  • ABSTRACT Needle-actuating cams for each of the feeds of a circular knitting machine are mounted on a separate cam-section block.
  • Each such cam-section block is formed with parallel planar side surfaces and with parallel planar front and rear surfaces, each cam section block has its cams mounted adjacent its front surface on an elongated member, and the blocks are arranged in a circular are around the machine with the cams facing the center of the circular arc and with a gap between adjacent blocks diverging in a direction away from said center.
  • Removable plate means serve as the only restraint against movement of the elongated member means in the direction of needle movement.
  • each such camsection block was generally of a size sufficient to support the cams of more than one feed and as a consequence its circumferential dimension was such as to limit the use of a set of blocks on different machines varying in size.
  • small sized camsection blocks which support only the cams for one feed of a circular knitting machine are formed with planar front and rear surfaces which are parallel to one another and with planar side surfaces which are parallel v to each other.
  • cam-section blocks readily useable on machines of various sizes, but they are more easily machined and therefore less costly to produce than the prior art cam-section blocks because they are without a curvature, and because of the parallel planar surfaces.
  • FIG. 1 is a plan view showing cam-section blocks according to the prior art on a circular knitting machine
  • FIG. 2 is a front face elevational view of one of the Y cam section blocks of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 showing camsection blocks according to the invention on a circular knitting machine;
  • FIG. 4 is a fragmentary perspective view showing a front end bottom portion of the cam-section block of FIG. 3;
  • FIG. 5 is a perspective view of one of the cam-section blocks of FIG. 3;
  • FIG. 6 is a vertical sectional view taken on the plane of the line 6-6 of FIG. 3.
  • FIG. 7 is an exploded view of one of the cam-section blocks in FIG. 3.
  • reference character 10 designates the annular base plate of a circular knitting machine having cam-section blocks of a well known type mounted thereon in accordance with conventional practice.
  • Three such cam-section blocks 12, 14, 16 supporting camming 18, 20 and 22 respectively are shown secured to the annular base plate 10 by bolts 24 in FIG. 1.
  • a typical arrangement of cams on such a cam-section block (block 12) may be seen in FIG. 2 wherein the earns 26, 28, and 32 are cams for one feed of the machine and earns 34, 36, 38 and are cams for another feed.
  • Cams 26, 28, 34 and 36 define a track for the butts of one set of cylinder needles and the earns 30, 32, 38 and 40 define a track for the butts of another set of cylinder needles.
  • the blocks 12, 14 and 16 have arcuate front surfaces 42, 44 and 46 respectively, arcuate rear surfaces 48, 50 and 52 respectively, and side surfaces 53, 54, 56, 58, and 61.
  • the arcuate surfaces are all concentric with the cylinder (not shown) of the machine, and the side surfaces all extend in a radial direction with respect to the cylinder of the machine.
  • cam section blocks according to the invention i.e., blocks 62, 64, 66, 68, and 72 are shown on the annular base plate 73 of a circular knitting machine in FIG. 3.
  • Such cam section blocks 62, 64, 66, 68, 70 and 72 are formed with planar front surfaces 74, 76, 78, 80, 82 and 84 respectively, and with planar rear surfaces 86, 88, 90, 92, 94 and 96 respectively.
  • the side surfaces designated by even numbered reference characters 98 through inclusive are also planar.
  • Cam-section blocks according to the invention may be used on different diameter machines accommodating an integral number of blocks by arranging said blocks on the machine with the angular separation between adjacent sides suited to the purpose. Also, since all surfaces on the blocks are planar the cost of producing such blocks is minimal. Other advantages are also realized because of the particular way in which the blocks of the invention are constructed as best seen in FIGS. 5 and 6 wherein one such block 62 is shown in some detail.
  • the cam-section block 62 is an assembly comprising a one-piece body portion 138 which includes a foot 140, a side plate 142, and cam-supporting elongated blocks 144 and 146.
  • the blocks 144 and 146 are slidably mounted in a cutout comer 148 of body portion 138 with a projecting portion 149 that is formed on each block extending into a slot 150 formed in the body portion.
  • the elongated blocks are positioned as shown in body portion 138 between one end 151 of a torsion spring 152 and a bearing surface 154 under the head 156 of a bolt 158 having a threaded connection with body portion 138, and the plate 142 thereafter being secured to the trailing side of the body portion 138 by screws 160 and 162 to serve as the only restraint against the movement of the elongated blocks 144, 146 in the direction of needle movement relative to the cam section block 62.
  • the blocks 144 and 146 are slidably adjustable as a unit by bolt 158 against a biasing force exerted by spring 152 and are adjustable with respect to each other with a screw 164 having a threaded connection with elongated block 146 and extending through the block 146 to contact block 144..
  • the camming 126 mounted on cam section block 62 is shown as consisting of a raise cam 166 and a stitch cam 168 fastened to elongated block 144 by screws 170 and 172 respectively, and a raise cam 174 and a stitch cam 176 fastened to elongated block 146 by screws 178 and 180 respectively.
  • Cams 166 and 168 define a track for the butts of one set of knitting needles and the cams 174 and 176 define a track for another set of needles.
  • a multi-feed circular knitting machine comprising a plurality of cam-section blocks; esblpcks be ng ,L:s hape a1it a m p g o o and rearwardly'extending foot portion, andeac block fin laa lslrlanapppqsite s de yrta9 st9 fi a leading and a trailing side in relation to the direction of needle movement, parallel planar opposite end surfaces, and parallel planar top and bottom surfaces generally defining the L-shaped outline of the block; means for mounting needle actuating cams for one feed only on the front upright portion of each block; a ring for supporting said cam-section blocks around a circular arc concentric with the cylinder of the machine, with the cams facing the center of the arc, and with adjacent side surfaces of the cam-section blocks extending in diverging direction outwardly from said center; and a fastener at the foot portion of each block for securing the foot portions of the blocks to
