Abstract
Abstract A floating boom end connector, for joining the end of an elongated floating material containment boom to the juxtaposed end of a similar boom or to a towing or anchoring plate, incorporates a vertically elongated extrusion having a central web portion joined to the vertically arrayed flat boom fin end by means of an enlarged vertical central cavity within which the fin end is firmly anchored by being bent and re-curved around a central core, or is wedged between two flanking wedging bars secured to the fin end inside the cavity. The end connectors are provided with interfitting scraph jaws locking together two mating connectors or one connector and a mating towing plate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A tension transmitting connector for the end of a flat vertically arrayed fin of an elongated floating material containment boom, for joining said end thereof to a tension-applying towing or anchoring plate or to the juxtaposed end of a similar boom, comprising: A. a vertically elongated central tow flange portion juxtaposed to said flat fin end and incorporated a distal engaging portion for interlocking engagement with the adjacent distal towing plate or anchoring plate of an adjacent connector, wherein the engaging portion comprises a raked, tension-carrying scarph jaw forming a scarph joint interlocking the tow flange with a mating scarph jaw of a tow flange of the adjacent connector; B. two intermediate vertically elongated sidewall portions extending laterally divergingly from the central flange portion to define an enlarged vertical central cavity embracing the vertical fin end and reconverging to form facing proximal end flanges sandwiching the fin end therebetween in a narrow vertical proximal entrance portal slot; and c. a vertically elongated anchoring core positioned inside the central cavity co-acting with the fin end and blocking its withdrawal through the portal slot.
Claim 2
Dependent Claim
182 words
A tension transmitting connector for the end of a flat vertically arrayed fin of an elongated floating material containment boom, for joining said end thereof to a tension-applying towing or anchoring plate or to the juxtaposed end of a similar boom, comprising: A. a vertically elongated central tow flange portion juxtaposed to said flat fin end and incorporated a distal engaging portion for interlocking engagement with the adjacent distal towing plate or anchoring plate of an adjacent connector, wherein the engaging portion comprises a raked, tension-carrying scarph jaw forming a scarph joint interlocking the tow flange with a mating scarph jaw of a tow flange of the adjacent connector; B. two intermediate vertically elongated sidewall portions extending laterally divergingly from the central flange portion to define an enlarged vertical central cavity embracing the vertical fin end and reconverging to form facing proximal end flanges sandwiching the fin end therebetween in a narrow vertical proximal entrance portal slot; and c. a vertically elongated anchoring core positioned inside the central cavity co-acting with the fin end and blocking its withdrawal through the portal slot.
Claim 3
Dependent Claim
71 words
The connector defined in claim 1, wherein the anchoring core is a vertical bar positioned within the vertical central cavity, with the flat fin end extending into and through the portal slot, curving around and encircling the bar between the bar and the sidewalls and re-emerging through the portal slot, thus forming a bight portion whose withdrawal through the portal slot is blocked by the bar encircled by the bight portion.
Claim 4
Dependent Claim
29 words
The connector defined in claim 2, wherein the facing surfaces of the vertical bar and the sidewalls are formed with traction surfaces engaging the fin end bight portion therebetween.
Claim 5
Dependent Claim
46 words
The connector defined in claim 2, wherein the sidewalls bounding the central cavity are formed in a wavy corrugated configuration with undulating vertical lobes, and wherein the vertical bar is correspondingly lobed to force the fin end bight portion into tractive engagement with the sidewall lobes.
Claim 6
Dependent Claim
69 words
The connector defined in claim 1, wherein the fin end projects directly through the portal slot into the central cavity without curving, and wherein the anchoring core is divided into two vertical wedging bars secured to the fin end and flanking the fin end inside the central cavity, blocking withdrawal of the fin end through the portal slot by wedging jamming engagement with the sidewalls bounding the central cavity.
Claim 7
Dependent Claim
21 words
The connector defined in claim 5, wherein the wedging bars are provided with traction surfaces engaging the flat fin end therebetween.
Claim 8
Dependent Claim
25 words
The connector defined in claim 1, wherein the facing end flanges are drawn together to compress the boom fin end therebetween by through bolt means.
