Definitions

  • the invention concerns tufting machines and has more particular reference to a needle-bar push-rod arrangement.
  • the primary object of the present invention is to provide a simple, yet efiective, means for enabling a ready adjustment of the extreme position of the needle-bar, at the lower end of its stroke, to take place.
  • a needle-bar assembly for a tufting machine which assembly includes a push-rod, an extension arm releasably secured to the push-rod at the remote end thereof a mounting bracket attached to the extension arm likewise at the remote end thereof, and lateral support blocks secured to the said mounting bracket.
  • a needle-bar assembly for a tufting machine includes a push-rod, an extension arm releasably secured to the remote end of the push-rod, the said extension arm comprising a rigid elongate member attached to the end of the push-rod in co-axial relationship therewith, and a mounting bracket attached to the said member at the free end thereof.
  • FIG. 1 is a section through a push-rod having an extension according to the invention applied thereto;
  • FIG. 2 is a perspective view, partly in section, of the pushrod extension of FIG. 1.
  • a push-rod 11 is slidably mounted in a casing 12, the casing 12 being carried in a machine center-beam l3, and an extension 14 is secured to the lower end of the push-rod by a cap-screw 15 extending axially thereof.
  • a mounting bracket 16 to the opposite sides of which lateral support-blocks 17 are secured, as by welding, is attached to the lower end of the extension, such bracket being releasably attachable to the extension by a clamping screw 18 engaged with a threaded bore 19 in the bracket and receiving a needle-bar 20 at the underside thereof.
  • the needle-bar is attached to the bar by cap-screws 21 extending through the lateral support-blocks 17 to engage screw-threaded holes in the needle-bar, the undersides of the support-blocks 17 being flush with the undersides of the mounting bracket.
  • extension 14 is stepped, as is clearly apparent in FIG. 1 of the drawings, to engage a complementary formation at the lower end of the push-rod whilst at its lower end, the extension is counterbored to receive the head of screw 15.
  • the shoulder formed at the upper end of the extension defines an axial flange to engage a counter-bore in the lower end of the push-rod
  • a needle-bar assembly including a push-rod, an extension-arm releasably secured to the remote end of the push rod, the said extension-arm comprising a rigid elongate member attached to the end of the push-rod in coaxial relationship therewith, said elongate member having an axially directed bore therein, the outer end of said member being counterbored, an attachment screw having a head portion thereon, said head portion being received in said counterbore, and a mounting bracket attached to the said member at the free end thereof.
  • said stepped configuration comprises a peripheral step adjacent said end of said elongate member.
  • said mounting bracket includes support blocks secured thereto at opposite sides thereof.
