Abstract
Abstract A device for applying ''''stops'''' to a spinnaker sail comprising a hollow tubular member through which the sail is passed. The sail is thereby compressed into a tight roll configuration and elastic bands positioned on the tubular member are slipped off of the tubular member and onto the sail as it exits from the member to maintain the sail in a tight roll configuration.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A device for applying stops to a spinnaker sail comprising an elongated hollow member having first and second open end portions through which the spinnaker sail is passed, said first and second end portions serving as entrance and exit ends respectively, said member having a cross-sectional dimension sufficient to compress said spinnaker sail into a relatively tight elongated roll as said sail is passed therethrough, and a means on said second end portion for supporting discrete binder devices which are removed from said second end portion and thereby are applied to said spinnaker sail as it exits from said second end portion to maintain said sail in said roll configuration.
Claim 2
Independent Claim
110 words
A device for applying stops to a spinnaker sail comprising an elongated hollow member having first and second open end portions through which the spinnaker sail is passed, said first and second end portions serving as entrance and exit ends respectively, said member having a cross-sectional dimension sufficient to compress said spinnaker sail into a relatively tight elongated roll as said sail is passed therethrough, and a means on said second end portion for supporting discrete binder devices which are removed from said second end portion and thereby are applied to said spinnaker sail as it exits from said second end portion to maintain said sail in said roll configuration.
Claim 3
Dependent Claim
29 words
The device of claim 1 and including a radially outwardly flared flange surrounding said first open end portion to facilitate the entrance of said spinNaker sail into said member.
Claim 4
Dependent Claim
13 words
The device of claim 2 and including a finger-hold attachment on said flange.
Claim 5
Dependent Claim
13 words
The device of claim 1 wherein said binder devices are endless elastomeric bands.
Claim 6
Dependent Claim
56 words
The device of claim 1 wherein the means for supporting said binder devices comprises a surface area of said member, and a longitudinally extending wedge-shaped member affixed to said surface area and over which said binder devices are positioned, said wedge member raising said binder devices above said surface to facilitate grasping said discrete binder devices.
Claim 7
Dependent Claim
13 words
The device of claim 1 wherein said member is of circular cross section.
Claim 8
Dependent Claim
21 words
The device of claim 6 wherein said dimension of said cross-section progressively diminishes from said first end to said second end.
Claim 9
Dependent Claim
12 words
The device of claim 1 wherein said device is rectangular in cross-section.
Claim 10
Dependent Claim
21 words
The device of claim 8 wherein said dimension of said cross-section progressively diminishes from said first end to said second end.
