Definitions

  • Cited structure includes a channel formed in the front surface UNITED STATES PATENTS of the bar, the channel being adapted to closely receive the rear edge portion of the block therein to maintain a predetermined alignment.
  • the present invention relates to a tufting machine for forming cut pile fabric, and more particularly to the means for mounting the cutting knives in a tufting machine.
  • a machine of this type generally includes a plurality of needles for carrying the yarn strands through the backing fabric, a coopcrating looper associated with each needle for engaging and retaining the formed yarn loops, and a knife mounted on an oscillating knife bar for severing the yarn loops retained on the loopers.
  • the knife In tufting machines of the above described type, it is conventional for the knife to be retained and held in a knife block, which in turn is carried by the oscillating knife bar such that the knife is reciprocated across the looper with a scissors-like cutting action.
  • the knife block is mounted on the bar by means of a laterally extending shaft on the block which is inserted into a mating opening in the bar.
  • a locking set screw is provided on the bar which engages the shaft to secure the same in the opening and thereby maintain the alignment of the block.
  • means for connecting the knife block to the knife bar which includes a channel formed in the front surface of the bar, the channel being adapted to closely receive the rear edgeportion of the knife block therein.
  • a cylindrical shaft extends from the rear edge portion of the knife block, and a cylindrical opening extends into the channel on the knife bar, for closely receiving the cylindrical shaft.
  • a threaded aperture which extends into the bar and communicates with the cylindrical opening, and a locking screw is adapted to be threadedly received in the aperture to engage the shaft.
  • the shaft of the block is inserted into the cylindrical opening of the bar until the rear edge portion of the block is received in the conforming channel.
  • the knife carried by the block will be in the desired predetermined position with respect to the loopers when the block is so received in the channel of the knife bar.
  • the locking screw is then rotated to engage the shaft to prevent withdrawal thereof. In this position, relative rotational movement between the block and bar is precluded by the closely conforming interconnection between the channel and block rear edge portion, and this relationship may be maintained with very little tightening of the locking screw.
  • the danger of disfigurement to the shaft by over tightening of the locking screw is alleviated.
  • FIG. 1 is a fragmentary perspective view, partly sectioned, of a severing mechanism in a cut pile tufting machine and which embodies the present invention
  • FIG. 2 is a fragmentary front elevational view of the knife block and bar illustrated in FIG. 1;
  • FIG. 3 is a fragmentary top plan view of the knife block and bar shown in FIG. 2.
  • FIG. 1 illustrates a severing mechanism in an otherwise conventional cut pile tufting machine, and which embodies the features of the present invention.
  • the machine includes a plurality of reciprocating needles 10, each of which carries a yarn 11 through a backing fabric (not shown) to form a plurality of tufting loops.
  • a plurality of loopers 12 is secured to a looper head 14 such that each looper is operatively associated with one of the needles to engage and retain the tufting yarn loops.
  • a cutting knife 16 is operatively associated with each looper to sever the yarn loops, the knives 16 being mounted for oscillatory movement in relation to the loopers.
  • the knives are carried by a knife block 20 which in turn is mounted on an oscillating knife bar 22.
  • a plurality of blocks 20 is mounted on the bar 22, with each block being carried in a predetermined angular relationship with respect to the bar such that each knife will properly engage the associated looper 12and sever the yarn in a scissors-like oscillating movement.
  • the knife block 20 comprises a generally rectangular unitary body member having an I-shaped crosssectional configuration, and defines a forward edge portion including the generally planar surface 23, and a rear edge portion including the generally planar surface 24.
  • a central connecting web 25 interconnects the forward and rear portions and defines a pair of knife mounting grooves 26 and 27.
  • the block further includes oppositely facing planar side edge surfaces 29 and 30,'each of which are partially cut away along a vertical direction to open communication with the associated grooves 26 and 27.
  • a pair of spaced-apart slots 32 and 34 are provided which extend laterally into the surface 23 of theforwardedge portion and into communication with the two grooves 26 and 27.
  • a U-shaped clamping bracket 36 is adapted to enter the lateral slots 32 and 34 such that the legs of the bracket will engage the two knives positioned in the grooves at two spaced locations.
  • the bracket 36 is maintained in this position by means of the threaded cap screw 38 which extends freely through the aperture 39 and is received in the threaded aperture 40 which extends laterally into the forward edge portion between the two slots.
  • the knife bar 22 is of generally rectangular cross section, and the illustrated right angled cross section defines a horizontal direction 42 and a vertical direction 44.
  • the bar defines a front surface 46 having a plurality of closely spaced vertically directed channels 48 extending along the longitudinal length thereof.
  • Each of the channels has a U- shaped cross-sectional outline and defines a planar medial surface 50 and opposed side surfaces 52 and 53 extending perpendicularly from the medial surface 50.
  • the side edge surfaces 52 and 53 are parallel and define planes which extend at an angle of about 12 from the vertical direction 44 and at an angle of about from the horizontal direction 42. This predetermined angular relationship is typical for certain tufting machines and insures that the knives 16 are maintained in a predetermined relationship with respect to the loopers 12 as will become more apparent.
  • the means for connecting the knife block to the bar further includes a cylindrical shaft 56 connected at one end to the lower portion of the rear edge surface24 of the block 20.
  • the shaft 56 extends outwardly from the surface 24 in a generally perpendicular direction, and is adapted to be closely received in one of the cylindrical openings 58 which extend horizontally through the bar.
  • each of the cylindrical openings 58 communicates with the medial surface 50 of one of the channels 48, and extends perpendicular thereto.
  • each channel 48 has a U-shaped cross-sectional outline defined by the planar medial surface 50 and opposed side edges 52 and 53, and the rear edge portion of each block has a closely conforming U-shaped cross-sectional outline defined by the planar rear edge surface 24 and the oppositely facing side edgesurfaces 29 and 30.
  • the rear edge surface 24 of the block will closely overlie the channel medial surface 50 and the channel side edge surfaces 52 and 53 will closely overlie the block side edge surfaces 29 and 30 to thereby preclude relative rotational movement between the block and bar about the axis of the shaft 56.
  • means for locking the shaft 56 in the opening 58 which comprises a threaded aperture 60 extending vertically into the bar and communicating at substantially right angles with the opening.
  • a threaded locking screw 62 is adapted to be threadedly received in the aperture 60 and engage the shaft 56.
  • the present invention provides a novel knife block connecting structure whereby the cutting knives 16 are automatically and accurately aligned in relation to the loopers upon the block being mounted on the bar.
  • the connecting structure is simple and foolproof, and does not require any additional structural components.
  • a tufting machine for forming a cut pile fabric and including means for carrying a yarn through a backing fabric to form a plurality of tufting loops therein, the combination therewith of looper means operatively associated with said yarn carrying means for engaging and retaining the tufting loops, and means operatively associated with said looper means for severing the tufting loops while retained by said looper means and including a knife bar mounted for oscillatory movement in relation to said looper means and defining a front surface, a knife block defining a rear edge portion positioned opposite said knife bar from surface, a knife carried by said knife block and adapted to cooperate with said looper means in severing the yarn loop upon relative oscillatory movement between the knife bar and looper means, and means for connecting said knife block to said knife bar in a predetermined angular relationship such that the knife is maintained in a predetermined relationship with respect to said looper means, said connecting means including a channel formed in said bar front surface, said channel having a crosssectional outline
  • said channel has a U-shaped cross-sectional outline defining a planar medial surface and opposed side edge surfaces
  • said block rear edge portion has a U-shaped cross-sectional outline defining a planar rear edge surface and oppositely facing side edge surfaces, whereby said block planar rear edge surface closely overlies said channel medial surface and said channel side edge surfaces closely overlie said block side edge surfaces to thereby preclude relative rotational movement between said knife block and said knife bar.
  • said means for locking said shaft in said opening includes a threaded aperture extending into said bar and communicating at substantially right angles with said cylindrical opening, and a locking screw adapted to be threadedly received in said threaded aperture and engage said shaft.
