Abstract

Abstract Apparatus including multiple lines extending between spaced locations where a midline takeup device is supported on said lines between said locations constructed to pay out and take in such lines to accommodate slackening and tensioning effects in such lines between said two locations. The device includes a collector holding stored portions of the lines, and is constructed so that parallel reaches of the lines extend out in opposite directions from the collector. The collector may comprise axially spaced mating reel sections, with one holding stored portions of one line and the other holding stored portions of the other line, and a helical spring located between and housed within the reel sections urging rotation of the collector in a direction producing simultaneous takeup of both lines.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 47 words
The apparatus of claim 1, wherein the takeup device includes a collector mounting, the collector is rotatably mounted on said mounting, and spring means is provided interposed between the collector and mounting urging rotation of the collector in a direction producing simultaneous taking up of both lines.
Claim 2
Dependent Claim 46 words
The apparatus of claim 2, wherein guide means is provided mounted on said collector mounting spaced radially from the rotation axis of the collector, said guide means being forced against sides of said lines by the reaction force produced in said mounting by said spring means.
Claim 3
Dependent Claim 52 words
The apparatus of claim 1, wherein the collector comprises a spring member which extends in a curved course about the rotation axis of the collector, the lines are operatively secured to the spring member, and the stored portions of both lines extend along such course and are supported by such spring member.
Claim 4
Dependent Claim 60 words
The apparatus of claim 1, wherein the collector comprises axially spaced mating reel sections joined together, one holding stored portions of one line and the other holding stored portions of the other line, and a helical spring is located between and housed within the reel sections urging rotatioN of the collector in a direction producing simultaneous takeup of both lines.
Claim 5
Dependent Claim 56 words
The apparatus of claim 5, which further comprises a collector mounting which includes a portion which is disposed between the reel sections and encircles said spring, said spring having one end anchored to the mounting and an opposite end anchored to the reel sections, said mounting carrying means rotatably supporting the reel sections on the mounting.
Claim 6
Dependent Claim 43 words
The apparatus of claim 6, wherein the collector mounting extends radially of the collector beyond the periphery of the reel sections, and a guide is mounted on said collector mounting on such projecting portion of the collector which is urged against said lines.
