Abstract
Abstract A pair of sliding wedges having oppositely directed parallel frictional gripping surfaces are mounted on a base and slide on inclined wedging surfaces. The wedges are spring biased to closed nip position, but permitted to slide against the bias of the spring to facilitate entry of a line between the opposed frictional gripping surfaces while preventing retrograde movement by the presence of the line within the nip.

Claim 1
Independent Claim
236 words
A wedge cleat for releasably holding a yacht working line, said cleat comprising: a base, opposed blocks mounted on said base and defining a pair of oppositely inclined sliding wedge surfaces, a pair of wedge elements in sliding contact with said sliding wedge surfaces and having parallel confronting faces forming a line-receiving nip therebetween, line engagement means on respective wedge elements permitting said sliding wedge elements to be relatively displaceable from said minimum nip position with said sliding wedge surfaces being configured to effect increased nip gap dimension upon relative movement of said sliding wedge elements, such that a line moved towards said nip in a direction radially of the line and in contact with said line engagement means effects relative displacement between said sliding wedge elements in selfinduced fashion to the dimension necessary to receive the line within the nip causing said action, said sliding wedge element carrying a hole whose axis is in alignment with the sliding wedge surface in respective contact therewith, a pin cantilever fixed to each block and having a free end portion extending within a respective hole and being of a diameter slightly less than the diameter of said hole to guide the movement of each element, and a linear coil spring concentrically carried by each pin with its ends respectively compressed between the sliding wedge element and said block for biasing said sliding wedge elements towards closed nip position.

A wedge cleat for releasably holding a yacht working line, said cleat comprising: a base, opposed blocks mounted on said base and defining a pair of oppositely inclined sliding wedge surfaces, a pair of wedge elements in sliding contact with said sliding wedge surfaces and having parallel confronting faces forming a line-receiving nip therebetween, line engagement means on respective wedge elements permitting said sliding wedge elements to be relatively displaceable from said minimum nip position with said sliding wedge surfaces being configured to effect increased nip gap dimension upon relative movement of said sliding wedge elements, such that a line moved towards said nip in a direction radially of the line and in contact with said line engagement means effects relative displacement between said sliding wedge elements in selfinduced fashion to the dimension necessary to receive the line within the nip causing said action, said sliding wedge element carrying a hole whose axis is in alignment with the sliding wedge surface in respective contact therewith, a pin cantilever fixed to each block and having a free end portion extending within a respective hole and being of a diameter slightly less than the diameter of said hole to guide the movement of each element, and a linear coil spring concentrically carried by each pin with its ends respectively compressed between the sliding wedge element and said block for biasing said sliding wedge elements towards closed nip position.
Claim 3
Dependent Claim
149 words
A wedge cleat comprising: a base, an abutment mounted to said base having a serrated face, a block mounted on said base and defining an opposed sliding wedge surface intersecting a plane including the serrated face of said abutment, a sliding wedge element positioned for sliding movement along said sliding wedge surface and having a parallel confronting face wih said serrated abutment face to form a line-receiving nip therebetween, said sliding wedge element including a hole extending within the same whose axis is parallel to the sliding wedge surface, a pin cantilever fixed to said block with a free end received within said hole and being of a diameter slightly less than the diameter of said hole, and a coil spring concentrically carried by said pin and compressed between opposed faces of said block and said sliding wedge element for biasing said sliding wedge element toward closed nip position.

Dependent Claim
149 words
A wedge cleat comprising: a base, an abutment mounted to said base having a serrated face, a block mounted on said base and defining an opposed sliding wedge surface intersecting a plane including the serrated face of said abutment, a sliding wedge element positioned for sliding movement along said sliding wedge surface and having a parallel confronting face wih said serrated abutment face to form a line-receiving nip therebetween, said sliding wedge element including a hole extending within the same whose axis is parallel to the sliding wedge surface, a pin cantilever fixed to said block with a free end received within said hole and being of a diameter slightly less than the diameter of said hole, and a coil spring concentrically carried by said pin and compressed between opposed faces of said block and said sliding wedge element for biasing said sliding wedge element toward closed nip position.
Claim 5
Dependent Claim
231 words
A wedge cleat comprising: a base, opposed blocks mounted on said base, confronting recesses formed within said opposed blocks defining a pair of oppositely inclined sliding wedge surfaces and fixed abutment means at both ends of said sliding wedge surfaces, a pair of wedge elements positioned respectively within said recesses and in sliding contact with the sliding wedge surfaces for movement between said abutments and having opposed, parallel, confronting faces forming a line-receiving nip therebetween, each sliding wedge element including a hole extending within the same whose axis is parallel to said sliding wedge surface, a pin fixed to each block anD extending away from one of said abutments in cantilever fashion with a free end received within said hole having a diameter slightly less than said hole, and a coil spring concentrically surrounding each pin and compressed between opposed surfaces of said one abutment and said sliding wedge element for biasing said sliding wedge elements towards closed nip position and line contact means on the ends of said sliding wedge elements remote from said biasing spring, permitting said sliding wedge elements to be relatively displaceable against said bias from said minimum nip position by a line moving towards said nip in a direction radially of the line to effect relative displacement between said sliding wedge elements and said line to a dimension necessary to receive the line within said nip.
Claim 6

A wedge cleat comprising: a base, opposed blocks mounted on said base, confronting recesses formed within said opposed blocks defining a pair of oppositely inclined sliding wedge surfaces and fixed abutment means at both ends of said sliding wedge surfaces, a pair of wedge elements positioned respectively within said recesses and in sliding contact with the sliding wedge surfaces for movement between said abutments and having opposed, parallel, confronting faces forming a line-receiving nip therebetween, each sliding wedge element including a hole extending within the same whose axis is parallel to said sliding wedge surface, a pin fixed to each block anD extending away from one of said abutments in cantilever fashion with a free end received within said hole having a diameter slightly less than said hole, and a coil spring concentrically surrounding each pin and compressed between opposed surfaces of said one abutment and said sliding wedge element for biasing said sliding wedge elements towards closed nip position and line contact means on the ends of said sliding wedge elements remote from said biasing spring, permitting said sliding wedge elements to be relatively displaceable against said bias from said minimum nip position by a line moving towards said nip in a direction radially of the line to effect relative displacement between said sliding wedge elements and said line to a dimension necessary to receive the line within said nip.
Claim 7
Dependent Claim
