Definitions

  • a device comprises input means mounted for rotation about an input axis, and including input joint means eccentric to the input axis; and output means mounted for angular movement about an output axis transverse to the input axis, and including output joint means eccentric to the output axis and connected with the input joint means,
  • FIG. 2 is a plan viewillustrating a modification in which the input joints are connected by a doublearmed link with the output joint means;
  • FIG 3 is a fragmentary perspective view of another embodiment in which the input shaft carries'a wobble plate so that input and output jointsnt halves can be directly connected;
  • FIG. 4 is a fragmentary schematic plan view illustrating a modification in which the output axis perpendicu-' larly crosses the input axis spaced therefrom, which results in an asymmetrical oscillation of the output shaft;
  • FIG. 5 is a fragmentary plan view illustrating another embodiment in which the input means is reciprocated in axial direction in addition to its rotary motion, which results in a variationof the angular speed of the output means;
  • FIG. 6 is a schematic plan view illustrating a modification of the embodiment of FIG. 2 in which the output axis is not perpendicular to the input axis, but intersects the inputaxis at an acute angle.
  • the input means include an inputshaft 1, and a'flange 2 secured to the input shaft and carrying an eccentric input joint 3 radially spaced from the'axis of input shaft 1.
  • the output means includes an annular frame 6, and output shaft portions 7, 7' fixedly secured to the frame 6. Outputs joints 5 and 5 are provided in diametrical positions on the annular frame 6, and are engaged by the two aligned arms 4a of a T-shaped link means whose longer arm 4 is connected with the input joint '3.
  • link means 4, 4a is driven by the eccentric input joint 3 so that the annular frame 6 together with the output shaft 7, 7 is angularly oscillated over an angle a.
  • the output shaft portion 7 is preferably directly connected with the holding member of a weft inserting needle which is then oscillated at the same angular acceleration and deceleration as output shaft portion 7.
  • FIG. 4 is a modification of the embodiment of FIG. l-and FIG. 2, and has an input shaft 31 carrying a transversely projecting member or flange 32 connected by an eccentric joint means 33 with a T-shaped link means 34, 34a located in joints in the annular frame 36 of the output shaft 37.
  • FIG. 1 corresponds substantially to the embodiment of FIG. 1, and includes an input shaft 41 carrying a transverse member 42 with a joint 43 connected with a T-shaped link 44 who shorter arms are located in openings 45 and 45' in the annular frame 46 which rigidly connects the output shaft portions 47, 47'.
  • the embodiment of FIG. 6 may have a second input shaft portion, and flange 62', as described with reference to the embodiment of FIG. 2 and FIG. 4, and the embodiment of FIG. 5 may also be provided with an additional input shaft portion and flange connected by a double armed link.
  • Device as claimed in claim 4 comprising support means for mounting said input means and output means in a position in which said output axis crosses said input axis spaced from'said input axis so that the oscillatory motion of said output means is asymmetrical.
  • a device for transferring rotary motion into oscillatory motion comprising input means mounted for rotation about an input axis, and including input joint means eccentric to said input axis; operating means for axially reciprocating said input'means during rotation thereof; and output means mounted for angular movement about an output axis transverse to said input axis, and including output joint means eccentric to said output axis and connected with said input joint means so that rotation of said input causes oscillatory angular motion of said output means at a cyclically varying speed.
