Ship/offshore window for permanent mounting in the external steel bulkhead of a wall

Abstract

A ship/offshore window for permanent mounting in the external steel bulkhead of a wall, for example by welding, comprising a window frame, preferably of steel, for pressure-proof and airtight retention of a plurality of glass members having different desired properties for rendering the window unit pressure/explosion-proof, for example, fireproof, soundproof and light/heat reflective, in various degrees and both separately and in various combinations. The desired glass members are assembled in a hermetically sealed package of glass members wherein the marginal edges of the pressure-proof glass members project beyond the marginal edges of the other glass members. Said two sets of marginal edges are surrounded by a similarly offset (in cross section) protective/retainer frame, the projecting portion of said frame and the projecting edges of the pressure-proof glass members being intended to be retained tightly but detachably between the inside surface of the window frame and inwardly projecting fastening means secured to the window frame. The fastening means comprise inwardly projecting screw bolts on the inside of the frame with clamping disks having one or more holes which are aligned with said screw bolts and which are intended to cooperate with the offset portion of the retainer frame, as well as nuts for tightening the clamping disks against said offset frame portion.
