Abstract
Abstract Apparatus for storing a cable with fairing sections consists of a pair of spaced-apart drums, the outer surfaces of both having a helix, the helix on one drum being in the opposite direction to that on the other drum. The cable is wound on the inner drum and then passed through an opening in the outer drum for winding thereon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
Apparatus for storing a cable comprising first rotatable drum means, second rotatable drum means spaced apart from and substantially surrounding said first drum means, means for arresting rotation of said second drum means, and access means for passage of said cable from said first drum means after winding thereon, onto said second drum means; and means for locking said second drum means to said first drum means comprising a ramp means attached to said first drum means, an overlying chamber means attached to said second drum means, said ramp communicating with said chamber to cause a locking action between said first and second drum means when said cable overlies said ramp in passage from said first drum means to said second drum means.
Claim 2
Dependent Claim
123 words
Apparatus for storing a cable comprising first rotatable drum means, second rotatable drum means spaced apart from and substantially surrounding said first drum means, means for arresting rotation of said second drum means, and access means for passage of said cable from said first drum means after winding thereon, onto said second drum means; and means for locking said second drum means to said first drum means comprising a ramp means attached to said first drum means, an overlying chamber means attached to said second drum means, said ramp communicating with said chamber to cause a locking action between said first and second drum means when said cable overlies said ramp in passage from said first drum means to said second drum means.
Claim 3
Dependent Claim
31 words
Apparatus according to claim 1, including means for winding said cable on said second drum means in a reverse direction to the winding of said cable on said first drum means.
Claim 4
Dependent Claim
44 words
Apparatus according to claim 2, wherein said first and second drum means include a helical groove on their respective outer surfaces to receive said cable, the helical groove of said second drum means being opposite to said helical groove on said first drum means.
Claim 5
Dependent Claim
36 words
Apparatus according to claim 1, wherein said second drum means has a transverse slot to permit said cable to be wound upon and unwound from said first drum means when said second drum means is stationary.
Claim 6
Dependent Claim
27 words
Apparatus according to claim 1, wherein direct drive means are included for said first drum means, whereas said second drum means is bearingly mounted for independent rotation.
Claim 7
Dependent Claim
74 words
Apparatus according to claim 1, having a third spaced-apart, rotatable drum means surrounding said second drum means, individual means for arresting said third drum means, a transverse slot in said third drum means to permit said cable to be unwound from said second drum means when said third drum means is stationary through said individual arresting means, said slot in said third drum means being larger than said slot in said second drum means.
Claim 8
Dependent Claim
30 words
Apparatus according to claim 3, wherein said second drum means has guide means to guide said cable from said access means into said helical groove on said second drum means.
Claim 9
Dependent Claim
165 words
Apparatus for storing a cable comprising first rotatable drum means, second rotatable drum means spaced apart from and substantially surrounding said first drum means, means for arresting rotation of said second drum means, and access means for passage of said cable from said first drum means after winding thereon, onto said second drum means; means for winding said cable on said second drum means in a reverse direction to the winding of said cable on said first drum means; and helical groove means on the outer surfaces of said first and second drum means respectively to receive said cable, the helical groove of said second drum means being opposite to said helical groove of said first drum means, and wherein the depth of the helical groove of said first drum means is sufficient to substantially envelope said cable, said second drum means being flexible to an extent such as to permit it to contract under cable tension into load-bearing contact with said first drum means.
