Abstract

723,722. Metal window and door frames. HOPE & SONS, Ltd., H. Nov. 16,1953 [Nov. 20, 1952], No. 29317/52. Class 20(3). Transverse T-section metal bars c are secured to metal window, or door, frames formed of tubular bars a of rectangular section by means of attachment pieces d secured to the ends of the bars c and adapted to fit into corresponding openings f in the inner faces of the bars a. The attachment pieces d, secured by tenons c to the transverse bars, abut against, and are screwed to, posts g screwed to the inner faces of the bars a. In alternative arrangements the posts g are omitted, fixing screws being inserted through the attachment pieces d for engagement with screwed holes in the opposite side of the frame member, or vice-versa. The end portions of the bars c are cut away to enable the members to fit together evenly.
