Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
240 words
A guide for leading, into a keyway on a luff-supporting member, a bead on the luff edge of a sail, said guide comprising: a pair of rounded sail-engaging elements; a generally C-shaped yoke connecting and supporting said sailengaging elements in spaced relationship with a predetermined gap therebetween and with a generally open area included within said elements and said C-shaped yoke, the size of the gap permitting passage of said sail between said sail-engaging portions while retaining said bead within said open area; and means linking said yoke for connecting said guide to a relative3y fixed point adjacent the base of said keyway, said yoke being shaped in an arcuate form around said gap permitting said guide to rotate relative said linking means to enable the side of said gap opposite said yoke to face to either side of said keyway, the portions of said yoke adjacent said rounded sail-engagIng elements being spaced further from said gap than the portion of said yoke opposite said gap whereby the orientation of said guide tends to be stable with said linking means under tension when said gap is facing one side or the other and tends to be unstable with said linking means located opposite said gap whereby a sail being led into said keyway by said guide bends over one or the other of said rounded sailengaging elements with the body of the sail lying to one side of said guide.
Claim 2
Dependent Claim
240 words
A guide for leading, into a keyway on a luff-supporting member, a bead on the luff edge of a sail, said guide comprising: a pair of rounded sail-engaging elements; a generally C-shaped yoke connecting and supporting said sailengaging elements in spaced relationship with a predetermined gap therebetween and with a generally open area included within said elements and said C-shaped yoke, the size of the gap permitting passage of said sail between said sail-engaging portions while retaining said bead within said open area; and means linking said yoke for connecting said guide to a relative3y fixed point adjacent the base of said keyway, said yoke being shaped in an arcuate form around said gap permitting said guide to rotate relative said linking means to enable the side of said gap opposite said yoke to face to either side of said keyway, the portions of said yoke adjacent said rounded sail-engagIng elements being spaced further from said gap than the portion of said yoke opposite said gap whereby the orientation of said guide tends to be stable with said linking means under tension when said gap is facing one side or the other and tends to be unstable with said linking means located opposite said gap whereby a sail being led into said keyway by said guide bends over one or the other of said rounded sailengaging elements with the body of the sail lying to one side of said guide.
Claim 3
Dependent Claim
17 words
A guide as set forth in claim 1 wherein said sail-engaging elements are integral with said yoke.
Claim 4
Dependent Claim
19 words
A guide as set forth in claim 1 wherein said linking means includes a tie-ring slidable along said yoke.
Claim 5
Dependent Claim
236 words
A guide for leading, into a keyway on a luff-supporting member, a bead on the luff edge of a sail, said guide comprising: a generally C-shaped yoke; a pair of rounded sail-engaging elements extending inwardly from the ends of said C-shaped yoke to a gap therebetween, there being a generally open area included within said elements and said C-shaped yoke, the size of the gap permitting passage of said sail between said sail-engaging portions while retaining said bead within said open area, the center of curvature of at least the inner surface of said yoke being outside of said gap relative said yoke; and a ring linking and slidable along said yoke by means of which said guide is flexibly connected to a relatively fixed point adjacent the base of said keyway, said yoke being shaped in an arcuate form around said gap permitting said guide to rotate relative said ring to enable said gap opposite to face to either port or starboard as a sail is raised from aft of said luff-supporting member, whereby the orientation of said guide tends to be stable with said gap facing starboard or port and tends to be unstable with said gap facing aft whereby a sail being led into said keyway by said guide bends over one or the other of said rounded sail-engaging elements with the body of the sail lying to one side of said guide.
Claim 6
Dependent Claim
236 words
A guide for leading, into a keyway on a luff-supporting member, a bead on the luff edge of a sail, said guide comprising: a generally C-shaped yoke; a pair of rounded sail-engaging elements extending inwardly from the ends of said C-shaped yoke to a gap therebetween, there being a generally open area included within said elements and said C-shaped yoke, the size of the gap permitting passage of said sail between said sail-engaging portions while retaining said bead within said open area, the center of curvature of at least the inner surface of said yoke being outside of said gap relative said yoke; and a ring linking and slidable along said yoke by means of which said guide is flexibly connected to a relatively fixed point adjacent the base of said keyway, said yoke being shaped in an arcuate form around said gap permitting said guide to rotate relative said ring to enable said gap opposite to face to either port or starboard as a sail is raised from aft of said luff-supporting member, whereby the orientation of said guide tends to be stable with said gap facing starboard or port and tends to be unstable with said gap facing aft whereby a sail being led into said keyway by said guide bends over one or the other of said rounded sail-engaging elements with the body of the sail lying to one side of said guide.
Claim 7
Dependent Claim
246 words
A jib sail system comprising: a hollow, slotted headstay adapted to receive a bead on the luff edge of a jib with the body of the sail extending through the slot, a portion of the slot being opened to a width which will receive said bead, and a guide including: a generally C-shaped yoke; a pair of rounded sail-engaging elements extending inwardly from the ends of said C-shaped yoke to a gap therebetween, there being a generally open area included within said elements and said C-shaped yoke, the size of the gap permitting passage of said sail between said sail-engaging portions while retaining said bead within said open area, the center of curvature of at least the inner surface of said yoke being outside of said gap relative said yoke; a ring linking and slidable along said yoke; and means flexibly connecting said ring to a relatively fixed point adjacent the base of said headstay, said guide being rotatably relative said ring to enable said gap opposite to face to either port or starboard as a sail is raised from aft of said headstay, whereby the orientation of said guide tends to be stable with said gap facing starboard or port and tends to be unstable with said gap facing aft whereby a sail being led into said keyway by said guide bends over one or the other of said rounded sail-engaging elements with the body of the sail lying to one side of said guide.
