Abstract
A strong modular cylinder is made to a selected length by using rods through rings and spacers to tension the cylinder and helical truss rods to give further strength. The ring configuration provides a large open area which can be compartmented for adaptations such as of suction or vacuum boxes.
Claims7
A pin and truss cylinder construction comprising a plurality of support rings, said support rings including regularly spaced pin rod openings therethrough and regularly spaced helical truss rod openings therethrough, a plurality of spacers, said spacers between at least two support rings, a plurality of pin rods, each said pin rod adapted to pass through at least some of said spacers and through said support rings and said pin rod openings, said pin rods threaded at each end and having nuts on said threads to tension said pin rods against said rings and spacers therebetween, said support rings and spacers and tensioned pin rods forming a cylindrical configuration, and a plurality of helical truss rods, each said helical truss rod adapted to pass through at least some of said support rings' helical truss rod openings, means to fasten said helical truss rods to the cylindrical configuration formed by said support rings and spacers and pin rods.
