Abstract
Abstract A self-aligning bobbin chuck for use with a yarn winding apparatus of the type that includes a drive roll and means for moving a bobbin carried by the chuck into surface driven engagement with the drive roll. The chuck includes concentrically arranged and radially spaced, first and second shafts and a sleeve telescoped over the shafts. The second shaft has a portion that extends beyond one end of the first shaft and is pivotally mounted at a point between its ends to the first shaft for swinging movement in a plane inclusive of the longitudinal axes of both the chuck and the drive roll. The sleeve is rotatably mounted to one end of the second shaft while a damping means is coupled between the other end of the second shaft and the first shaft to dampen out rapidly applied shock loads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
A bobbin chuck for use with a yarn winding apparatus that includes a drive-roll and support means for moving a bobbin carried by said chuck into surface driven engagement with said roll, said chuck comprising: a first shaft connected at one of its ends to said support means said shaft and said drive-roll having substantially parallel longitudinal axes; a second shaft substantially coaxial with and pivotally mounted at a point between its ends to said first shaft for swinging movement in a plane inclusive of the axes of the second shaft and said drive roll; a sleeve rotatably mounted to said second shaft, said sleeve telescoped over said shafts; and means coupled between said shafts for damping movement therebetween.
Claim 2
Dependent Claim
119 words
A bobbin chuck for use with a yarn winding apparatus that includes a drive-roll and support means for moving a bobbin carried by said chuck into surface driven engagement with said roll, said chuck comprising: a first shaft connected at one of its ends to said support means said shaft and said drive-roll having substantially parallel longitudinal axes; a second shaft substantially coaxial with and pivotally mounted at a point between its ends to said first shaft for swinging movement in a plane inclusive of the axes of the second shaft and said drive roll; a sleeve rotatably mounted to said second shaft, said sleeve telescoped over said shafts; and means coupled between said shafts for damping movement therebetween.
Claim 3
Dependent Claim
167 words
A bobbin chuck for use with a yarn winding apparatus that includes a drive-roll and support means for moving a bobbin carried by said chuck into surface driven engagement with said roll, said chuck comprising: a first shaft connected at one of its ends to said support means, said shaft being hollow and having a concentric inner and outer walls, said drive-roll and said shaft having substantially parallel longitudinal axes; a second shaft having one end extending into and its opposite end extending out from said first shaft, said second shaft being concentric with, radially spaced from, and pivotally mounted at a point between its ends to said first shaft for swinging movement in a plane inclusive of said axes; a sleeve rotatably mounted to said opposite end and telescoped over and radially spaced from said opposite end and telescoped over and radially spaced from said first shaft; and means coupled between said one end and the inner wall of said first shaft for damping movement therebetween.
Claim 4
Dependent Claim
167 words
A bobbin chuck for use with a yarn winding apparatus that includes a drive-roll and support means for moving a bobbin carried by said chuck into surface driven engagement with said roll, said chuck comprising: a first shaft connected at one of its ends to said support means, said shaft being hollow and having a concentric inner and outer walls, said drive-roll and said shaft having substantially parallel longitudinal axes; a second shaft having one end extending into and its opposite end extending out from said first shaft, said second shaft being concentric with, radially spaced from, and pivotally mounted at a point between its ends to said first shaft for swinging movement in a plane inclusive of said axes; a sleeve rotatably mounted to said opposite end and telescoped over and radially spaced from said opposite end and telescoped over and radially spaced from said first shaft; and means coupled between said one end and the inner wall of said first shaft for damping movement therebetween.
Claim 5
Dependent Claim
46 words
The bobbin chuck as defined in claim 2, wherein said damping means includes diametrally opposed members extending radially outwardly from said second shaft against said inner wall and resilient means within said second shaft and contacting said members for urging them outwardly against said inner wall.
Claim 6
Dependent Claim
18 words
The bobbin chuck as defined in claim 3 said opposed members extending radially outwardly substantially in said plane.
Claim 7
Dependent Claim
29 words
The bobbin chuck as defined in claim 4, said second shaft having a cavity therein, said resilient means being a silicone material confined in said cavIty by said members.
Claim 8
Dependent Claim
14 words
The bobbin chuck as defined in claim 5, said material being a silicone polymer.
