Abstract
Abstract A device for the storage of filamentary material includes a storage member supported from a support member for rotation with respect thereto, the storage member having a free end over which stored material can be taken off, the storage member having at its free end a cross-sectional area declining toward that free end, the device comprising an annular member surrounding the storage member adjacent the free end thereof, the opening of the annular member having a cross-sectional area declining toward the free end for checking ballooning of the filamentary material during take-off.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
128 words
A device for the storage of filamentary material comprising a support member, a storage member supported from the support member for rotation about an axis with respect thereto, the storage member having a free end over which stored material can be taken off, the storage member having at its free end a portion of cross-sectional area declining toward that free end, the device further comprising an annular member surrounding at least a portion of the storage member adjacent the free end thereof, the opening of the annular member having a cross-sectional area declining toward said free end for checking ballooning of the filamentary material during take-off, the device further including means to impose a cyclical relative motion on the storage member and annular member parallel to said axis.
Claim 2
Independent Claim
128 words
A device for the storage of filamentary material comprising a support member, a storage member supported from the support member for rotation about an axis with respect thereto, the storage member having a free end over which stored material can be taken off, the storage member having at its free end a portion of cross-sectional area declining toward that free end, the device further comprising an annular member surrounding at least a portion of the storage member adjacent the free end thereof, the opening of the annular member having a cross-sectional area declining toward said free end for checking ballooning of the filamentary material during take-off, the device further including means to impose a cyclical relative motion on the storage member and annular member parallel to said axis.
Claim 3
Independent Claim
149 words
A device for the storage of filamentary material comprising a support member, a storage member supported from the support member for rotation about an axis with respect thereto, the storage member having a free end over which stored material can be taken off, the storage member having at its free end a portion of cross-sectional area declining toward that free end, the device further comprising an annular member surrounding at least a portion of the storage member adjacent the free end thereof, the opening of the annular member having a cross-sectional area declining toward said free end for checking ballooning of the filamentary material during take-off, the device further including means to adjust the position of the annular member relative to the storage member lengthwise of said axis to adjust the resistance to passage of a thread through the opening formed between the annular member and the storage member.
Claim 4
Independent Claim
149 words
A device for the storage of filamentary material comprising a support member, a storage member supported from the support member for rotation about an axis with respect thereto, the storage member having a free end over which stored material can be taken off, the storage member having at its free end a portion of cross-sectional area declining toward that free end, the device further comprising an annular member surrounding at least a portion of the storage member adjacent the free end thereof, the opening of the annular member having a cross-sectional area declining toward said free end for checking ballooning of the filamentary material during take-off, the device further including means to adjust the position of the annular member relative to the storage member lengthwise of said axis to adjust the resistance to passage of a thread through the opening formed between the annular member and the storage member.
Claim 5
Dependent Claim
251 words
Apparatus for the accumulation and temporary storage of lengths of filamentary material withdrawn from a supply, said apparatus comprising a hollow rotatable shaft, a bearing supporting the shaft for rotation, a storage member rotatably supported at one end from the shaft, means restraining the storage member against rotation, a flyer arm affixed to the shaft and extending radially and axially into exterior overlapping relation with the storage member at said one end thereof, the storage member having a smooth exterior surface conforming substantially to a surface of revolution, said exterior surface including at said one end a substantially frusto-conical portion aligned with said flyer arm, the large end of said portion being adjacent said shaft, a filamentary material passing through the hollow rotatable shaft and over the flyer arm being laid on said exterior surfaces of the storage member into a single layer wrapping of filamentary material on said surfaces whereby the turns of the single layer wrapping of the filamentary material so laid onto said member by said flyer arm are readily axially slideable toward the opposite end of said storage member, said exterior surface further including at said opposite end of the storage member a substantially frusto-conical portion the small end of which is remote from said one end, said apparatus further comprising an annular member surrounding with clearance said last-named portion, the opening of the annular member having over at least part of the axial length of said last-named Portion a cross-sectional area declining toward said opposite end.
