Abstract

Abstract This disclosure pertains to a line gripping device such as a rope puller, a wire puller, or a cleat. The line gripping device utilizes both the camming and the jamming action. More particularly, the disclosure illustrates a handle attached to a base with a first jaw member adjustably but firmly attached to the base. A second jaw member is mounted on the base adjacent the first jaw member with the gripping teeth of the jaw members spaced apart a sufficient distance to permit a rope to be inserted therebetween. The second jaw member is mounted for movement toward and away from the first jaw member by a camfollower arrangement so that the first and second jaw members are constantly maintained in a parallel relationship. Accordingly, tension on a line placed between the jaws causes a camming operation to force the jaws together to grip the line while the angular relationship of the teeth causes the line to be jammed between the jaws. In another embodiment of the disclosure, the jaws are mounted on a base which is secured by screws to a deck of a vessel so as to form a combination jam-cam cleat.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 268 words
A line gripping device comprising: (a) a base member, (b) a first jaw member fixedly mounted to said base member and having an angularly disposed face with alternate ridges and grooves disposed at an angle on said face, (c) a second jaw member disposed on said base in juxtaposed relation to said first jaw member and having an angularly disposed face with alternate ridges and grooves disposed at an angle on said face, (d) said faces of said first and second jaw members being spaced apart to form a generally V-shaped opening into which a line to be gripped may be easily guided, (e) said base member and said second jaw member having a pair of cooperating cam follower-cam slots thereon with said cam slots being parallel to each other and having angular paths whereby said second jaw member is mounted on said base for free movement toward and away from said first jaw members in a parallel relationship, (f) said alternate ridges and grooves causing said second jaw member to automatically move toward said first jaw member when tension is applied to a line between the jaws and causing automatic movement away from said first jaw member upon relaxation of tension to release said line, (g) said V-shaped slot permitting easy ingress and egress of said line while tension on the line tends to force the line to the bottom of the V to increase the grip on the line, said cam slots extending generally perpendicular to said faces of said first and second jaw members and having a portion of their path varying from the perpendicular.
Claim 2
Dependent Claim 268 words
A line gripping device comprising: (a) a base member, (b) a first jaw member fixedly mounted to said base member and having an angularly disposed face with alternate ridges and grooves disposed at an angle on said face, (c) a second jaw member disposed on said base in juxtaposed relation to said first jaw member and having an angularly disposed face with alternate ridges and grooves disposed at an angle on said face, (d) said faces of said first and second jaw members being spaced apart to form a generally V-shaped opening into which a line to be gripped may be easily guided, (e) said base member and said second jaw member having a pair of cooperating cam follower-cam slots thereon with said cam slots being parallel to each other and having angular paths whereby said second jaw member is mounted on said base for free movement toward and away from said first jaw members in a parallel relationship, (f) said alternate ridges and grooves causing said second jaw member to automatically move toward said first jaw member when tension is applied to a line between the jaws and causing automatic movement away from said first jaw member upon relaxation of tension to release said line, (g) said V-shaped slot permitting easy ingress and egress of said line while tension on the line tends to force the line to the bottom of the V to increase the grip on the line, said cam slots extending generally perpendicular to said faces of said first and second jaw members and having a portion of their path varying from the perpendicular.
Claim 3
Dependent Claim 54 words
A line gripping device according to claim 1 wherein said cam slots are recessed within said base member and accomadate the mounting means for said first jaw member to secure said first jaw member in a selected position in said cam slots to adjust the initial spacing between said first and second jaw members.
Claim 4
Dependent Claim 47 words
A line gripping device according to claim 1 wherein said base member is provided with end walls between which said first and second jaw members are mounted and wherein said end walls are provided with guide means to facilitate positioning of the line between said jaw members.
Claim 5
Dependent Claim 38 words
A line gripping device according to claim 3 wherein a handle is secured to said base member adjacent one of said end walls to facilitate moving said line gripping device into and out of contact with a line.
