rods being woven together in mesh form and providing a reinforcement of the thickness or depth of two of the rods, and glasses adapted to be secured in the square openings of the reinforcement, each glass having lateral projections spaced apart vertically a distance equal to the thickness or depth of the reinforcement, the uppermost projection being adapted to bear against the top of the reinforcement, and the under projections consisting of lugs adapted to be disposed toward the corners of the reinforcement opening when the glass is inserted and when the glass is turned adapted to bear against the under side of the reinforcement.

3. The combination of reinforcing rods arranged to form square glass receiving spaces, a circular glass having a flange adapted to rest on the top of the rods, lugs projecting

from the glass beneath the flange for passing beneath the rods, the glass being bulged above the lugs for the purpose described.

4. The combination of resilient rods spaced apart to form glass receiving spaces, and glasses formed with lateral enlargements, the glasses being adapted to enter between the rods when the enlargements are not disposed toward the same, the enlargements being adapted when the glasses are turned to impinge the rods and be thus held there-between.
