Definitions

  • ZNVENTOR Werner GrendaLmei-zr 511a may:
  • the present invention relates to a knitting machine with at least one needle bed with guideways for the needles, and needles in the needle bed with each needle having a needle butt with a short projection parallel to the needle shank.
  • the object of the present invention is to avoid these disadvantages by providing a'patterning device for knitting machines of the said type in which the correct guiding of the needle butts can be definitely assured without a great expenditure of force,
  • a patterning device in accordance with the present invention is characterized by the fact that the paths lie in two super-imposed planes at the path alignment area.
  • FIGURE 1 is an elevation of a needle butt
  • FIGURE 2 is a cross-section through the patterning device taken along the line 2-2 of FIGURE 3 in the direction of the arrows;
  • FIGURE 3 is a cross-section through the patterning device taken along the line III--III of FIGURE 2 in the direction of the arrows, and
  • FIGURE 4 is a perspective view of the patterning device, omitting all the frame parts.
  • the patterning device shown in the drawing is particularly suitable for use in hand-knitting'apparatus, in which case it is intended to be installed in a lock, which is movable as customary, at right angles to the needle guides 1 of a needle bed 2.
  • This lock has not been shown in the drawing, in order not to clutter it unnecessarily.
  • the patterning device itself consists of a frame or framing 3 which is bent over at its longitudinal sides and has a base plate 3a.
  • a number of cam blocks are installed to form the two intersecting paths 4 (dotdash line) and 5 (dashline) which have aligned spaced portions.
  • the patterning device is positioned on the needle bed 2 and may be secured to the usual cam block (not shown) which is displaceable transverse to the needle bed (in the direction of the arrow 14, FIGURE 3) 1'11. order to actuate the needles.
  • auxiliary cam block 10 On the side of the central cam 'block 7, opposite the auxiliary cam block 6, there is another auxiliary cam block 10 which, however, is at right angles to the needle bed and extends parallel to and at a certain distance from the facing edge of the center cam block 7, the camblock part parallel to the direction of displacement being marked 10a and the part extending parallel to the inclined edge 7f being marked 1%.
  • the inclined part 10b is cut out in its lower half and does not extend down to the plane A.
  • a holddown spring 11 is so arranged that it rests resiliently on the outlet side of the device against the needle bed 2.
  • cam blocks 6, 7 and it define, as seen from below, the two paths 4 and 5, the path 4 being defined by the cam block 10 and edge of the extension 7d opposing the same, the lifting surface 70 and the central part 7e.
  • the path 5 is defined by the edge of the auxiliary cam block 6 facing the auxiliary cam block it and, towards the outlet side, and also by a short length of the auxiliary cam block 10, namely, between the point of impingement 12 and the bend 13, from where it leaves the patterning device parallel to the direction of displacement below the cam block part b.
  • the needle butts 15 have a protruding projection 17 parallel to the needle shank 16.
  • the selection of the two planes, A and B, i.e. the position of the auxiliary cam block 6 and of the central cam block '7 is such that the lower plane A is just below the projection 17 of the needles in their working position, while the plane B is above the plane A and further above the corresponding projection 17 as long as the needles remain in their normal position within their guides.
  • a needle butt comes into position 19, substantially uninfiuenced by the cam blocks, moves along the projection 6a of the auxiliary cam block 6 into the patterning device, follows the bend to the start of the central part 6b, strikes at 12 against the end of the part Ilia of the cam block 10 which is parallel to the direction of displacement and leaves the device at the position 18 since the inclined part lllb of the cam block it? does not extend down to the lower plane A.
  • These needle butts which are guided on the path 5 are accordingly not lifted and move at all times in the same plane which corresponds, at least approximately, to plane A. Needle butts which enter in position 18 into the patterning device behave differently.
  • the needles or needle butts are left in their normal working plane, while on path 4 they are lifted by'the lifting surface 70 to the upper plane B and drop back again only after leaving the patterning device.
  • the crossing takes place on the length between the impingement point 12 and the bend 13, in which region the two paths extend on different planes.
  • the hold-down spring 11 which presses the needle shanks of the needles proceeding along the path 4 into their operating position if this has not been automatically done.
  • the function of the upwardly pointing extension 7b is to press down needle butts running on path 5 which, for one reason or another, lie too high and might, therefore, strike frontally against the drive cam block 7 to prevent a possible clamping of the lock.
  • a corresponding provision with regard to the path 4 is not necessary, since here the needle butts are guided upwards by the slanting surface 70 so that a needle but rising too much must in any case abut against this slanting surface 70.
  • the provision of the extension 711 is not absolutely necessary, but is a measure of precaution.
  • jack butts could also be used.
  • a patterning device'movable along the needle bed comprising a frame, a first cam block in said frame lying in a first plane parallel to the needle bed lower than the plane of said projections, said first cam block having an arm with a guiding edge parallel to the direction of movement of the device and corresponding to a first position of the needles, said first cam block having a second guiding edge extending obliquely to said direction of movement, a second cam block disposed in a plane perpendicular to the needle bed, said second cam block having a first guiding surface parallel to said direction of movement and corresponding to a second position of the needles and a second guiding surface obliquely disposed toward said first cam block, said second surface having its under part terminating at the height of said first plane, a third cam block parallel to the first cam block in a plane
