Definitions

  • the invention concerns connecting rods and has particular, though not exclusive, reference to a connecting rod for use in a tufting machine in the drive transmission to the knives or loopers thereof.
  • an adjustable connecting rod particularly for a tufting machine, comprises rod-parts arranged in end-to-end axial alignment, and a turn-buckle in screw-threaded engagement with such parts and adapted, upon rotation relative to such parts, to effect a relative movement therebetween in the axial direction thereof.
  • FIG. 1 is a side elevation, partly in section, of an adjustable connecting rod for use in transmitting a drive motion to the oscillating knife or looper shaft of a tufting machine;
  • FIG. 2 is a front elevation of the connecting rod of FIG. 1;
  • FIG. 3 is a partial section of a tufting machine embodying the adjustable connecting rod of the present invention.
  • a connecting rod comprises first and second rod-parts 11,12 arranged in axially aligned end-to-end disposition, a turn-buckle l3 screwthreadedly engaged with the respective adjacent ends of the two rod-parts, and an indicator means 14 for indicating, in a quantitative manner, the adjusted position of the assembly.
  • the first rod-part 11 carries a big-end section 16 at one end and the opposite end 110 is of reduced diameter for free sliding engagement with an axially directed blind bore 12a in the adjacent end of the second rodpart 12, such second rod-part 12 having a bifurcated remote end thereto, the individual limbs 12b of such bifurcated end receiving respective, axially aligned, bearings 17 therein.
  • the first and second rod-parts 11,12 are provided with respective screw-threads 18,19 for co-operation with respective complementary screw-threads 21,22 at the inner surface of the turn-buckle 13, the screwthread 18 being provided on an intermediate section 11b of the rod-part from which the reduced diameter end 11a thereof extends and the screw-thread 19 being provided at the end section of the other such part and radially outwardly of the blind bore 12a.
  • the turn-buckle 13 is provided with longitudinally extending ribs 13a at the outer surface thereof to facilitate gripping for adjustment purposes and a slit 13b is formed in the wall of the sleeve which defines the turnbuckle and at each end thereof, the said slits 13b extending from the extremity of the sleeve in the longitudinal direction thereof, and each terminating in an enlarged hole 13b.
  • a slit 13b is formed in the wall of the sleeve which defines the turnbuckle and at each end thereof, the said slits 13b extending from the extremity of the sleeve in the longitudinal direction thereof, and each terminating in an enlarged hole 13b.
  • an integrally formed lug 13c At either edge of each slit there is provided an integrally formed lug 13c, the paired lugs at each end being drilled and tapped to receive a clamping screw 20 whereby the turn-buckle may be locked in position relative to the rod-parts.
  • That end of the turn-buckle overlying the rod-part 12 is stepped, as at 13d, to receive a part 14a of the indicator means 14, such part 14a being secured to the turnbuckle by means of a screw.
  • the indicator means 14 comprises a circular scale attached to the turn-buckle, such scale being the part 14a aforesaid, for rotational and axial movement therewith, and a linear scale 14b secured in a recess 12!: in the rod-part 12, the linear scale 14b extending longitudinally of the rod-part and being held in position by screws.
  • the clamping screws 20 are slackened off and the turnbuckle 13 is rotated relative to the rod-parts 11,12 until a requisite relative axial position of such parts as shown by the indicator means 14 is achieved, the clamping screws 20 thereafter being tightened to maintain such relative disposition.
  • FIG. 3 The application of the connecting rod to a tufting machine is shown in FIG. 3 only, those parts of the tufting machine relevant to an understanding of the invention being shown in the drawing.
  • the tufting machine includes a frame 30 mounting a bed-plate 31 for supporting a backing fabric 32, the fabric 32 being advanced across the bedplate by means of a plurality of backing feed rolls 33, which feed the fabric to the machine from a suitable source (not shown), and a plurality of take-up rolls 34 at the output side of the machine.
  • a main shaft 35 is joumalled in frame 30, and is suitably driven by a motor (not shown) in well known manner.
  • the shaft 35 has an eccentric 36 supported thereon in driving relationship and a connecting rod 37 is disposed in surrounding engagement with the eccentric 36 so that rotary motion provided by the shaft 35 and the eccentric 36 will result in a substantially reciprocating motion of the connecting rod 37.
  • the needle bar 39 supports a needle 41 thereon for' reciprocation through the backing fabric 32,- there being a needle plate 42 on the' bed plate 31 to support the backing fabric 32 against the thrust of the needle 41.
  • a hook or looper 43 is supported beneath the bed plate 31 and is oscillated by a shaft 44 in known manner for co-operation with the needle 41 as the latter pierces the backing fabric 32 and carries a loop of yarn therethrough for forming the tufted pile.
  • the indicator means may take other forms than that described and illustrated. In some applications it may be found necessary to provide the co-operating male and female formations at the adjacent ends of the rod-parts.
  • a multi-needle tufting machine according to claim 1, wherein said indicator means comprises a scale part on the turn-buckle and a cooperable part on the aligned adjacent rod part.
  • a tufting machine according to claim 1 wherein one rod-part terminates in a big-end section and the other rod-part terminates in a bifurcation, the opposed limbs of such bifurcation having respective axially aligned bearings therein.
  • a tufting machine according to claim 3 wherein the said complementary part of the indicator means is carried by that rod-part which terminates in the bifurcation and the scale part is provided on the turn-buckle and directly adjacent to the scale part.
