Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
127 words
For use with a helicopter, a high-tension-wire-laying device comprising a main wire reel support frame, wire reel rotary mount means carried by said reel support frame, braking means carried by said reel support frame and positioned to engage said wire reel rotary mount means, wire guide means carried at one end of said support frame, electromechanical means one element of which is adapted to be carried by the helicopter and another element of which is carried by said support frame for actuating the braking means to control tension on wire being strung from a wire reel carried in said rotary mount means, and quick-disconnect attaching means carried by said main frame and adapted to be connected to the helicopter to release the main wire reel support frame.
Claim 2
Dependent Claim
127 words
For use with a helicopter, a high-tension-wire-laying device comprising a main wire reel support frame, wire reel rotary mount means carried by said reel support frame, braking means carried by said reel support frame and positioned to engage said wire reel rotary mount means, wire guide means carried at one end of said support frame, electromechanical means one element of which is adapted to be carried by the helicopter and another element of which is carried by said support frame for actuating the braking means to control tension on wire being strung from a wire reel carried in said rotary mount means, and quick-disconnect attaching means carried by said main frame and adapted to be connected to the helicopter to release the main wire reel support frame.
Claim 3
Dependent Claim
58 words
A high-tension-wire-laying device as claimed in claim 1 wherein said wire reel rotary mount means comprises a brakedrum and disc having a bearing opening therethrough rotatably mounted on said main frame and an axially slidable wire reel support shaft movable through a bearing support on said main frame and through the bearing opening in said brakedrum and disc.
Claim 4
Dependent Claim
59 words
A high-tension-wire-laying device as claimed in claim 1 wherein said braking means comprises a brake band passing about a brakedrum adapted to be connected to the wire containing reel, one end of said brake band being anchored to the main frame and the other end being moved into and out of engagement with the brakedrum by said electromechanical means.
Claim 5
Dependent Claim
49 words
A high-tension-wire-laying device as claimed in claim 3 wherein said electromechanical means is a battery driven electrical motor which drives a worm shaft to cause rocking movement of an arm to which the movable end of the brake band is attached to tension or slacken same about the brakedrum.
Claim 6
Dependent Claim
54 words
A high-tension-wire-laying device as claimed in claim 1 wherein said wire guide means is a noselike projection at one end of the main frame having a pair of spaced-apart horizontally disposed rollers and a pair of spaced-apart vertically disposed rollers between each pair of which passes the wire to be layed from said reel.
Claim 7
Dependent Claim
38 words
A high-tension-wire-laying device as claimed in claim 4 further comprising a battery and control cable and switch adapted to be carried by the helicopter and releasably connected to the electric motor which controls the tensioning of the brakedrum.
