Stowing apparatus for the connection cable of a central system for power supply to aircraft
First Claim
1. A power supply connection to an airport central power station;
- a portion of said airport having a gate 10, said gate having a bridge head 12;
a connection box 20 at said bridge head and a connecting cable 14 from said power station through said connection box to said bridge head;
cable stowing and coiling apparatus 22 at said bridge head to store and control said cable as it is run out to an aircraft;
said cable having a plug type connection at its free end adapted to cooperate with a corresponding connector at an aircraft;
said cable stowing apparatus comprising cable coiling apparatus 22 having a pair of drums;
one of said drums being a coiling drum and the other of said drums being a compensating drum on which the cable is stored without twisting;
said cable stowing and coiling apparatus 22 being suspended beneath said bridge head 12 of said gate 10 with its axis 24 extending vertically; and
a motor 26 connected to and adapted to drive said drums in both directions of rotation around said axis.

Abstract
A stowing apparatus for the connection cable of an airport central system for power supply to aircraft is constructed in the form of a double drum (22), said drum comprises a takeup or coiling drum (28) for the length of the connection cable to be run out and a compensating drum (26) coaxial therewith from which the cable is led to a fixed connection of the bridge head of the gate. On the compensating drum (26) a compensating length of the cable is loosely wound in such a manner that the spiral of the compensating length on rotation of the drum and uncoiling and coiling of the connection cable moves radially from the outside to the inside and from the inside to the outside respectively, radially extending support bearings (44) being provided to reduce friction. In this manner the necessary revolutions of the coiling drum (28) are compensated by the spiral of the cable compensation portion. The drive of the double drum is by an electric motor (76) and transmission gearing (78 and 82) in such a manner that a drum speed of about 6 rpm results.
