SYSTEM AND MACHINERY FOR CONSTRUCTION OF SHIP SECTIONS
First Claim
1. Construction system for ship'"'"''"'"'s sections comprising a first mechanized assembly area for assembly of flat plate sections from individual elements;
- a second mechanized assembly area, parallel to the first, for assembly of shaped plate sections from individual elements;
machines in each assembly area for the assembly of the corresponding type of plate section, said machines including means for positioning plates in proper orientation, and means for their assembly;
a single ship'"'"''"'"'s section assembly area associated with said several mechanized assembly areas and being substantially as long as a ship'"'"''"'"'s section; and
means in the latter area for assembling said flat and shaped plate sections into a ship'"'"''"'"'s section as a unit, and for further assembly operations, such as combining it with stiffeners.

Abstract
A system for construction of ship sections. Mechanized devices are provided for assembling two-dimensional and three-dimensional sections from individual parts, under control of automatic and easily computerized mechanisms for forming, positioning and welding the sections. Sequences or systems of such devices and control mechanisms, for making flat or three-dimensional sections, are largely disposed in parallel, and the materials are conveyed in uniform directions along the parallel lines. Intermediate storage facilities are provided for compensation of slack in any of the parallel systems. Also provided is an ultimate receiving and finishing section, for work on elements from the preceding sections. Ship plates move along the several lines on trolleys equipped with suitable holders, and are processed by multiplicities of steel plate processing machines, basically known by themselves but specially arranged to suit the new system.
