Abstract
Abstract A line end clamp for boat lines or the like, said clamp comprising a relatively rigid block with a pair of spaced substantially parallel bores extending therethrough for receiving a line, a hole passing transversely through one of the bores and off set therewith, and a clamping pin removably mounted in the hole for occupying a portion of the bore for retentatively compressing and clamping the line. The hole is provided with a pair of longitudinal slots, one of which is located in the linereceiving area of the associated bore such that the clamping pin may be keyed to either slot depending upon the type of rope being clamped.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A line clamping device comprising a relatively rigid clamping block, a pair of open-ended line-receiving holes extending through said block and being of approximately the same width as the line to be clamped, a pin-receiving hole in said block transversely overlapping and communicating with one of said linereceiving holes, and a clamping pin removably, retentatively positioned in said pin-receiving hole and significantly reducing a cross-sectional opening of said one line-receiving hole, said pin-receiving hole including at least two longitudinal keyways, one of which is in transverse overlapping relation with said one line-receiving hole, said clamping pin having a longitudinal key selectively positioned in one of said keyways, thereby determining the effective cross-sectional area of the opening in said one line-receiving hole.
Claim 2
Dependent Claim
121 words
A line clamping device comprising a relatively rigid clamping block, a pair of open-ended line-receiving holes extending through said block and being of approximately the same width as the line to be clamped, a pin-receiving hole in said block transversely overlapping and communicating with one of said linereceiving holes, and a clamping pin removably, retentatively positioned in said pin-receiving hole and significantly reducing a cross-sectional opening of said one line-receiving hole, said pin-receiving hole including at least two longitudinal keyways, one of which is in transverse overlapping relation with said one line-receiving hole, said clamping pin having a longitudinal key selectively positioned in one of said keyways, thereby determining the effective cross-sectional area of the opening in said one line-receiving hole.
Claim 3
Dependent Claim
29 words
The structure set forth in claim 1 wherein said two keyways are oppositely disposed of each other, the other of said keyways being remote from said one line-receiving hole.
Claim 4
Dependent Claim
19 words
The structure set forth in claim 2 wherein said pin-receiving hole is substantially perpendicular to said one line-receiving hole.
Claim 5
Dependent Claim
21 words
The structure set forth in claim 3 wherein each of said holes and said clamping pin are generally cylindrical in configuration.
Claim 6
Dependent Claim
98 words
A line clamping device comprising a rElatively rigid clamping block, a pair of spaced generally parallel line-receiving holes extending through said block, a pin-receiving hole in said block communicating with one of said line-receiving holes and substantially perpendicular thereto, said pin-receiving hole having a center line substantially offset from that of said one line-receiving hole, said pin-receiving hole having at least two keyways at different positions relative to said one line-receiving hole, and a clamping pin removably mounted in said pin-receiving hole, said clamping pin having an outwardly directed key portion alternately received by one of said keyways.
Claim 7
Dependent Claim
98 words
A line clamping device comprising a rElatively rigid clamping block, a pair of spaced generally parallel line-receiving holes extending through said block, a pin-receiving hole in said block communicating with one of said line-receiving holes and substantially perpendicular thereto, said pin-receiving hole having a center line substantially offset from that of said one line-receiving hole, said pin-receiving hole having at least two keyways at different positions relative to said one line-receiving hole, and a clamping pin removably mounted in said pin-receiving hole, said clamping pin having an outwardly directed key portion alternately received by one of said keyways.
Claim 8
Dependent Claim
30 words
The structure set forth in claim 5 wherein said line-receiving hole is provided with an inwardly protruding tooth adapted to retentatively engage the line when said clamping pin is inserted.
Claim 9
Dependent Claim
31 words
The structure set forth in claim 6 wherein said tooth is oppositely disposed one of said keyways to coactively compress the line when said key is inserted in said one keyway.
Claim 10
Dependent Claim
26 words
The structure set forth in claim 7 wherein said pin-receiving hole is generally cylindrical in configuration with two of said keyways being diametrically opposite each other.
