Abstract
Abstract This specification discloses a machine for forming structural sections. Such sections are usually made of a web plate and one or more flange plates. These plates are brought together each in a horizontal plane onto two conveyors, the web plate above the flange plate. The web plate is then pivoted to a position in a vertical plane and brought to position on the flange plate. The flange plate is then welded, riveted or cemented to the web plate. The web is swung up by a shaft which has a clamp mechanism attached to it. The web plate is brought into position on the roller conveyor or overhead cranes and clamped in place, the shaft and mechanism is then rotated to lift the web plate from the rollers and to swing the web plate to vertical position over the flange plate. The assembly is then moved past a welder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
A machine for forming structural shapes made up of at least a first plate and a second plate, means to move said first plate into said machine and means to move said second plate into said machine below said first plate and in a plane parallel to said first plate, means to move said second plate laterally to an assembling position, means to swing said first plate into a plane parallel to said second plate and means to move said first plate and said second plate into engagement with each other, and means to weld said plates together to form said section, and means to move said plates welded together from said machine.
Claim 2
Dependent Claim
113 words
A machine for forming structural shapes made up of at least a first plate and a second plate, means to move said first plate into said machine and means to move said second plate into said machine below said first plate and in a plane parallel to said first plate, means to move said second plate laterally to an assembling position, means to swing said first plate into a plane parallel to said second plate and means to move said first plate and said second plate into engagement with each other, and means to weld said plates together to form said section, and means to move said plates welded together from said machine.
Claim 3
Dependent Claim
32 words
The machine recited in claim 1 wherein said means to convey said plates into said machine and said means to move said plates from said machine comprises roller conveyors having driven rolls.
Claim 4
Dependent Claim
71 words
The machine recited in claim 2 wherein said means to swing said first plate comprises a swing frame having lateral members disposed below and between some of said rolls, a hinge rod extending parallel to said plates, the ends of said rolls adjacent said assembly position being fixed to said hinge rod, and means to swing said hinge rod to move said first plate to position perpendicular to said second plate.
Claim 5
Dependent Claim
49 words
The machine recited in claim 3 wherein means is provided oN said swing frame to clamp the edge of said plates remote from said rod and to hold said first plate to move said first plate onto said second plate when said plates are disposed perpendicular to each other.
Claim 6
Dependent Claim
56 words
The machine recited in claim 4 wherein a fourth conveyor made of vertically extending rolls is supported in position to support said first plate when said first plate is in position over said second plate, and permanent magnets are disposed between the rolls of said fourth conveyor for holding said first plate to said fourth rolls.
Claim 7
Dependent Claim
32 words
The machine recited in claim 4 wherein said means for moving said second plate laterally comprises a plurality of transfer members having lugs therein and means for moving said transfer members laterally.
Claim 8
Dependent Claim
40 words
The machine recited in claim 1 wherein said means for welding said plates together comprises a member supported adjacent said means to move said plates from said machine whereby said plates are welded together as they move from said machine.
