Abstract
Abstract The jib-furling apparatus disclosed herein employs a stay having a C-shaped cross section, the interior of the C shape being adapted to retain a bead on the luff of a jib sail, e.g. a bolt rope, with the sail extending through the mouth of the C. The upper and lower ends of the stay are provided with respective swivel means for attachment to the mast and bow respectively and a further swivel means is provided for coupling a halyard to the head of a jib thereby to permit raising of a jib held by the stay while permitting the stay to rotate without twisting the halyard around the stay.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
Jib-furling stay apparatus for use between the bow and mast of a sailboat, said apparatus comprising: a stay having at least a portion thereof of generally C-shaped cross section, the interior of the C-shaped cross section being adapted to retain a bead on the luff of a jib sail with the sail extending through the mouth of the C; first swivel means for attaching the upper end of said stay to said mast; second swivel means for attaching the lower end of said stay to said bow, said stay being thereby adapteD to provide support to said mast; means for selectively rotating said stay thereby to furl a jib held thereby around the stay; and third swivel means for coupling a halyard to the head of a jib to permit raising of jib having a bead passing within said stay while permitting said stay to rotate without twisting said halyard around said stay.
Claim 2
Dependent Claim
153 words
Jib-furling stay apparatus for use between the bow and mast of a sailboat, said apparatus comprising: a stay having at least a portion thereof of generally C-shaped cross section, the interior of the C-shaped cross section being adapted to retain a bead on the luff of a jib sail with the sail extending through the mouth of the C; first swivel means for attaching the upper end of said stay to said mast; second swivel means for attaching the lower end of said stay to said bow, said stay being thereby adapteD to provide support to said mast; means for selectively rotating said stay thereby to furl a jib held thereby around the stay; and third swivel means for coupling a halyard to the head of a jib to permit raising of jib having a bead passing within said stay while permitting said stay to rotate without twisting said halyard around said stay.
Claim 3
Dependent Claim
22 words
Apparatus as set forth in claim 1 wherein said second swivel means includes a spherical bearing which permits said stay to bow.
Claim 4
Dependent Claim
25 words
Apparatus as set forth in claim 1 wherein said means for rotating said stay includes a drum mounted on the lower end of said stay.
Claim 5
Dependent Claim
26 words
Apparatus as set forth in claim 1 wherein said second swivel means includes a thrust bearing facilitating free rotation of said stay while under substantial tension.
Claim 6
Dependent Claim
75 words
Apparatus as set forth in claim 1 wherein said third swivel means includes first and second members both of which surround said stay, a thrust bearing interposed between said members for permitting free relative rotation while said members are under axial load along said stay, means for attaching a halyard to one of said members outside of said stay, and means for attaching the bead of a jib sail to the other of said members.
Claim 7
Dependent Claim
24 words
Apparatus as set forth in claim 1 wherein the walls of said C are relatively thin with respect to the width of the C.
Claim 8
Dependent Claim
22 words
Apparatus as set forth in claim 1 wherein said stay comprises a strip of metal rolled to provide said C-shaped cross section.
Claim 9
Dependent Claim
35 words
Apparatus as set forth in claim 7 wherein said stay includes a major portion which is of C-shaped cross section and a minor portion at the lower end thereof which is of U-shaped cross section.
Claim 10
Dependent Claim
182 words
Jib-furling stay apparatus for use between the bow and mast of a sailboat, said apparatus comprising: a stay comprising a strip of metal rolled to provide a major portion of generally C-shaped cross section and a minor portion at the lower end thereof which is of U-shaped cross section, the interior of the C-shaped cross section being adapted to retain a bead on the luff of a jib sail with the sail extending through the mouth of the C; first swivel means for attaching the upper end of said stay to said mast; second swivel means for attaching the lower end of said stay to said bow and permitting both rotation and bowing of said stay, said stay being thereby adapted to provide support to said mast; means for selectively rotating said stay thereby to furl a jib held thereby around the stay; and third swivel means for coupling a halyard to the head of a jib to permit raising of jib having a bead passing within said stay while permitting said stay to rotate without twisting said halyard around said stay.
Claim 11
