Abstract
Abstract 1. A launcher for a tubular rocket having a frame comprising four longitudinal angle beams, one at each corner of the frame, a lattice of struts connecting the beams, a series of transverse plates for stiffening the frame and having U-shaped recesses in their upper edges, and a U-section trough welded into the Ushaped recesses; a guide rail support fixed to the upper surface of each of the upper two angle beams; a plurality of spacers at intervals along the upper surfaces of the guide rail supports the spacers varying in thickness from zero at the center to a maximum at each end of each support the thicknesses being so graduated that the upper faces of the spaces lie on a smooth curve; and two guide rails bolted to the guide rail supports and in contact with the upper surfaces of the spacers whereby each said guide rail is constrained in an upwardly curved position, towards the opposite ends thereof.

A launcher for a tubular rocket having a frame comprising four longitudinal angle beams, one at each corner of the frame, a lattice of struts connecting the beams, a series of transverse plates for stiffening the frame and having U-shaped recesses in their upper edges, and a U-section trough welded into the Ushaped recesses; a guide rail support fixed to the upper surface of each of the upper two angle beams; a plurality of spacers at intervals along the upper surfaces of the guide rail supports the spacers varying in thickness from zero at the center to a maximum at each end of each support the thicknesses being so graduated that the upper faces of the spaces lie on a smooth curve; and two guide rails bolted to the guide rail supports and in contact with the upper surfaces of the spacers whereby each said guide rail is constrained in an upwardly curved position, towards the opposite ends thereof.
Claim 3
Dependent Claim
132 words
A launcher for a tubular rocket having a frame comprising four longitudinal angle beams, one along each longitudinal edge of the frame, a lattice of struts connecting the beams, a series of transverse plates for stiffening the frame and having U-shaped recesses in their upper edges, and a U-section trough secured into the U-shaped recesses; a guide rail support fixed to the upper surface of each of the two upper angle beams; and a guide rail fixed to the upper face of each guide rail support; said guide rails being parallel and having chamfers on their adjacent upper edges, which chamfers are non-uniform in depth, the depth of said chamfers being so graduated as to provide an upwardly curved guiding surface from the center of each rail to each opposite end thereof.
