Abstract
Abstract A decorative partition or like curtain wall structure is disclosed which can be formed by stacking a number of elementary glass blocks within a generally rectangular supporting frame. Each glass block has at least top and bottom faces contoured correspondingly for interfitting engagement with similar faces of the upper and lower blocks. The opposite lateral faces of each block may also be contoured correspondingly for interengagement with similar lateral faces of the blocks on both sides. Vertical bracing rods can be used to increase the stability of the glass blocks.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A decorative, non-load-bearing glass wall structure comprising, in combination, a supporting frame, horizontally adjoining pairs of bracing rods supported vertically by said supporting frame, each of the pairs of bracing rods consisting of two horizontally spaced apart rods, each rod of each pair being in close contact with the adjoining rod of the adjoining pair, a plurality of glass blocks laid up between the spaced apart rods of each pair, each of said glass blocks having a pair of vertical side grooves engaging the rods, respectively, one of each pair of the rods having a top end portion which is shiftable upward away from the remaining part of the rod to provide between the rods of each pair of widened horizontal spacing through and from which the glass blocks can be slid down between the rods of the pair during the laying operation of the glass blocks.
Claim 2
Dependent Claim
147 words
A decorative, non-load-bearing glass wall structure comprising, in combination, a supporting frame, horizontally adjoining pairs of bracing rods supported vertically by said supporting frame, each of the pairs of bracing rods consisting of two horizontally spaced apart rods, each rod of each pair being in close contact with the adjoining rod of the adjoining pair, a plurality of glass blocks laid up between the spaced apart rods of each pair, each of said glass blocks having a pair of vertical side grooves engaging the rods, respectively, one of each pair of the rods having a top end portion which is shiftable upward away from the remaining part of the rod to provide between the rods of each pair of widened horizontal spacing through and from which the glass blocks can be slid down between the rods of the pair during the laying operation of the glass blocks.
Claim 3
Dependent Claim
37 words
The glass wall structure as set forth in claim 1 wherein each of said glass blocks has its top and bottom faces contoured correspondingly for interfitting engagement with similar faces of the overlying and underlying glass blocks.
Claim 4
Dependent Claim
55 words
The glass wall structure as set forth in claim 1 wherein each of said glass blocks is of a hollow, bottle-like configuration including a neck on its top face and a corresponding recess in its bottom face, said neck of each of said glass blocks being fitted in said recess of the overlying glass block.
Claim 5
Dependent Claim
44 words
The glass wall structure as set forth in claim 1 wherein said supporting frame is of a generally rectangular form having an upper horizontal header, a lower horizontal sill, and a pair of side jambs, said header being a beam with its bottom closed.
Claim 6
Dependent Claim
96 words
The glass wall structure as set forth in claim 4 wherein said shiftable top end portion of the rod has a downwardly extending pin which is upwardly slidably fitted in the top of the remaining part of the rod, said top end portion being slidably passed through the bottom of the header, whereby the top end portion can be outwardly slid into the header away from the remaining part of the rod, the part of said top end portion below the header being of a vertical length at least equal to the height of each block.
