Abstract
Abstract In large aircraft pieces of baggage are carried in containers which must be unloaded on arrival. The invention consists in apparatus for mechanically unloading the containers. This apparatus includes an open-ended channel into which baggage containers are introduced and clamped, and means for rocking the channel as a whole about a horizontal axis to bring a sidewall onto a sloping support, and then rocking back the channel and container but not the sidewall, so that the baggage slides out under gravity over the sloping sidewall.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
141 words
Apparatus for use in unloading baggage from an open-sided container comprising a horizontal base, mounted to rock about a horizontal axis, for the reception of the container, means for clamping the container to the base, a wall mounted to pivot relatively to the base about the same horizontal axis, means for locking the wall in a position at right angles to the base to close the open side of the container and retain baggage, means for rocking the locked base and wall as a whole about the horizontal axis to bring the wall into a downwardly inclined position with baggage retained in the container by the wall, and a support for the wall in this position, whereby on unlocking the wall and rocking the base and the container back again baggage slides out of the container onto the downwardly inclined wall.
Claim 2
Dependent Claim

Apparatus for use in unloading baggage from an open-sided container comprising a horizontal base, mounted to rock about a horizontal axis, for the reception of the container, means for clamping the container to the base, a wall mounted to pivot relatively to the base about the same horizontal axis, means for locking the wall in a position at right angles to the base to close the open side of the container and retain baggage, means for rocking the locked base and wall as a whole about the horizontal axis to bring the wall into a downwardly inclined position with baggage retained in the container by the wall, and a support for the wall in this position, whereby on unlocking the wall and rocking the base and the container back again baggage slides out of the container onto the downwardly inclined wall.
Claim 3
Dependent Claim
153 words
An apparatus according to claim 1, for use with a container having two open sides, comprising an underbase mounted to rock about a second horizontal axis parallel to that about which the base is mounted to rock, a second wall mounted to pivot about the second horizontal axis, means for locking the second wall in a position at right angles to the underbase to close the second open side of the container and retain baggage, and means for rocking the underbase, the base and the second wall as a whole about the second axis to bring the second wall into a downwardly inclined position with baggage retained in the container by the second wall, and a support for the second wall in this position, whereby on unlocking the second wall and rocking the underbase, the base and the container back again baggage slides out of the container onto the downwardly inclined second wall.
Claim 4
Dependent Claim
34 words
An apparatus according to claim 1 in which the means for clamping a container to the base comprise pivoted hooks mounted in the base to swing out of the base to engage the container.
Claim 5
Dependent Claim
29 words
An apparatus according to claim 2 in which the underbase is mounted on a hinge rod that is carried in fixed supports and that constitutes the second horizontal axis.
Claim 6
Dependent Claim
32 words
An apparatus according to claim 4 in which the base is mounted on a hinge rod which constitutes the axis about which the base rocks and which is carried by the underbase.
Claim 7
Dependent Claim
32 words
An apparatus according to claim 2 in which the underbase is of open construction and the means for rocking the base pass through the underbase and engage the base on its underside.
Claim 8
Dependent Claim
38 words
An apparatus according to claim 6 in which the means for rocking the underbase comprise two rams connected to the underside of the underbase, and the means for rocking the base comprise a ram passing through the underbase.
Claim 9
Dependent Claim
36 words
An apparatus according to claim 1 in combination with a dock at the height of the base for the passage of containers into the apparatus, and a conveyor at the base of the inclined wall support.
Claim 10
Dependent Claim
26 words
An apparatus according to claim 8 also comprising a second dock at the opposite end of the apparatus and at the height of the base thereof.
Claim 11
Dependent Claim
24 words
An apparatus according to claim 8 in combination with a framework supporting the base above ground level, the conveyor being taken below ground level.
