Abstract
Abstract Apparatus for assembling hull modules for shipbuilding comprising two opposed chassis for supporting longitudinal assemblies and opposed second devices for supporting deck and bottom assemblies, all being constructed to be moved in the vertical and horizontal directions to adjust the position of the respective assemblies. The chassis is supported on cars by a plurality of interconnected oil cylinders adapted to enable the chassis to float on the oil in the cylinders and to permit both tilting and lateral displacement of the chassis on the cars.

Claim 1
Independent Claim
163 words
Apparatus for assembling hull modules for shipbuilding, including upright, longitudinal assemblies, an upright deck assembly and a bottom assembly, comprising opposed cars to support a pair or upright longitudinal assemblies respectively at their bottom portions, said each car having a chassis adapted to be moved in the vertical and horizontal directions, opposed supporting means to support upright deck assembly and bottom assembly respectively and operable to be moved in the vertical and horizontal directions to permit assembly thereof with said longitudinal assemblies, and means to grip upper portions of said longitudinal assemblies and operable to be retracted from the gripping position, each car chassis being supported by a plurality of vertical oil cylinders which are communicated with each other through a common valve which is opened to enable the chassis to float on the oil in the cylinders and to permit tilting of the chassis, and separate oil cylinders to adjust the longitudinal tilt of said chassis and to laterally displace the chassis.
