Abstract
Abstract A loading chuck (25) suspended by a cable (C) for grasping a spool (S), including strand material (M) disposed thereon between the flanges (14, 15) thereof, in a container, transporting the spool to a position proximate a creel and orienting the spool for positioning on a creel spindle, includes a plurality of substantially parallel arms (50), shoes (60) carried by the arms, gripping elements (61; 80, 80') on the shoes for engaging the spool, a lifting link (20) adapted for attachment to the cable, a linkage (26) interposed between the lifting link and the arms and maintaining the arms substantially parallel through the extent of travel thereof to bring the gripping elements into and out of engagement with the spool, and a pivot (55) mounting the shoes relative to the arms for selectively rotationally orienting the spool. Another embodiment contemplates loading apparatus (110) mounting a plurality of chucks (125) including a support (120) attached to a lifting link, a plurality of blocks (130, 131) mounted on the support, each of the blocks carrying one of the chucks, a mechanism (135) selectively moving at least some of the blocks along the support for varying the distance between the chucks, and a chuck rotating mechanism (150, 151) for coordinated equiangular rotation of the chucks.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A loading apparatus suspended by a cable and having a plurality of chucks, each adapted for grasping a containerized spool, including strand material disposed thereon, transporting the spool to a position proximate a creel and orienting the spool for positioning on a creel spindle comprising, suspension link means adapted for attachment to the cable, support means suspended by said suspension link means, a plurality of block means mounted on said support means, each of said block means carrying one of the chucks, means for selectively moving at least some of said block means along said support means for varying the distance between the chucks, means mounting the chucks for rotation relative to said block means, and chuck rotation actuator means for effecting coordinated, equiangular rotation of the chucks.
Claim 2
Dependent Claim
128 words
A loading apparatus suspended by a cable and having a plurality of chucks, each adapted for grasping a containerized spool, including strand material disposed thereon, transporting the spool to a position proximate a creel and orienting the spool for positioning on a creel spindle comprising, suspension link means adapted for attachment to the cable, support means suspended by said suspension link means, a plurality of block means mounted on said support means, each of said block means carrying one of the chucks, means for selectively moving at least some of said block means along said support means for varying the distance between the chucks, means mounting the chucks for rotation relative to said block means, and chuck rotation actuator means for effecting coordinated, equiangular rotation of the chucks.
Claim 3
Dependent Claim
38 words
Apparatus according to claim 1, wherein said chuck rotation actuator means has projecting lever arms attached to said means mounting the chucks for rotation relative to said block means and connecting links joining each of said lever arms.
Claim 4
Dependent Claim
40 words
Apparatus according to claim 2, including a position biasing mechanism having cam means affixed to one of said lever arms and biased roller means engaging said cam means for biasing said chucks toward the extremities of the rotational travel thereof.
Claim 5
Dependent Claim
161 words
A loading apparatus suspended by a cable and having a plurality of chucks, each adapted for grasping a containerized spool, including strand material disposed thereon, transporting the spool to a position proximate a creel and orienting the spool for positioning on a creel spindle comprising, suspension link means adapted for attachment to the cable, support means having a bar suspended by said suspension link means, a plurality of block means mounted on said support means and slidably engaging said bar, each of said block means carrying one of the chucks, means for selectively moving at least some of said block means along said support means for varying the distance between the chucks, and interconnect links pivotally attached to at least some of said block means and pivotally attached to a pivot pin movable in a slot in a guide plate to move the chucks equal distances relative to said suspension link means, whereby said support means is maintained substantially horizontally balanced.
Claim 6
Dependent Claim
161 words
A loading apparatus suspended by a cable and having a plurality of chucks, each adapted for grasping a containerized spool, including strand material disposed thereon, transporting the spool to a position proximate a creel and orienting the spool for positioning on a creel spindle comprising, suspension link means adapted for attachment to the cable, support means having a bar suspended by said suspension link means, a plurality of block means mounted on said support means and slidably engaging said bar, each of said block means carrying one of the chucks, means for selectively moving at least some of said block means along said support means for varying the distance between the chucks, and interconnect links pivotally attached to at least some of said block means and pivotally attached to a pivot pin movable in a slot in a guide plate to move the chucks equal distances relative to said suspension link means, whereby said support means is maintained substantially horizontally balanced.
Claim 7
Dependent Claim
30 words
