Definitions

  • An automatic color-change mechanism for a shuttle embroidering machine has a pair of pusher guides arranged on a needle carriage and converging to a point at the front of the latter and at an acute angle to each other.
  • a. left hand pusher in one guide and a right hand pusher in the other are linked with a control bar movable transversely to the working direction of the needles.
  • the linkage levers are disposed at an angle to each other such that, as the control bar moves left, the left hand pusher is moved into working position while the right hand pusher is withdrawn and vice versa.
  • the color-change device or mechanism according to the invention has pairs of pusher guides arranged on a needle carriage and converging to a point at the front at an acute angle to each other.
  • a left-hand pusher running in one guide and a right-hand pusher running in the other guide are linked by pairs with a control bar movable transversely to the working direction of the needles, by connecting levers arranged at an angle to each other, in such manner that asthe control bar movesleft the left-hand pusher moves in its guide into the working position, and the right-hand pusher in the other guide assumes its resting position, whereas when the control moves right the pushers are brought into the opposite positions.
  • the device according to the invention has the advantage of being absolutely unsusceptible to trouble, even with the simplest design. Moreover, two-color embroidering is possible in all repeats by taking out the appropriate needles. Automatic color change as well as two-color embroidering are possible in the 4/4 repeat also.
  • FIG. 1 is a fragmentary top view of the colorchanging-mechanism, with the control bar moved to the left;
  • FIG. 2 is a sectional view taken along the line IIII of FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 which illustrates the position of a pair of connecting levers with needle pushers as the control bar is moved to the right; V
  • FIG. 4 is an elevational view in the direction of arrow IV in FIG. 3;
  • FIG. 5 is a fragmentary vertical section taken along the line V-V of FIG. 3;
  • FIG. 6 is atop view of a needle pusher with its needle
  • FIG. 7 is a sectional view taken along the line VII- VII of FIG. 6;
  • FIG. 8 shows a sectional view as taken along the line VIIIVIII of FIG. 6.
  • the automatic color changing device shown in FIGS. 1 and 3 comprises wedgeshaped guide pieces 2 and 3 fixed with-screws 4 on a needle carriage or needle rail 1 working transversely to the longitudinal axis thereof, so'that their acute-angled points 2' and 3' project alternately from opposite sides,
  • the control bar 10 can perform a limited movement of about 52 mm and runs in two sets of rollers 13 guiding its edges.
  • the righthand needle pushers 6 withthe needles 12 are brought into their working position (FIG. 3), and as the control bar is shifted to the left the same happens with the lefthand pushers 6, and the needles '12.
  • the left-hand pushers 6' are a mirror image of the right-hand pushers 6.
  • the position x of the needles on needle rail 1 is the same in the working position of the left and right-hand pushers 6 and 6'. Due to the left and right-hand pushers pushers 6 as the bar is moved to the right. Hence the color change can be effected by operating the control bar 10, without having to stop the machine.
  • the needle carriage 1 equipped with the device described has a height of only l2 mm approximately, including thecover (FIG. 4).
  • An automatic color-change mechanism for a shuttle embroidery machine having pairs of pusher guides arranged on a needle carriage and converging to a point at the front at an acute angle to each other, wherein for each 4/4 repeat a left-hand pusher running in one guide and a right-hand pusher running in the other guide are linked in pairs with a control bar movable transversely to the working direction of the needles by connecting levers disposed at an angle to each other such that as the control bar moves left the lefthandpusher moves in'its guide into working position, and the right-hand pusher in the other guide assumes its resting position, while as the control bar moves right the pushers are brought into positions opposite thereto.
