Abstract

9534. Gilberthorpe, G. L., and Marshall, H. C. April 22. Venetian blinds. - Relates to fire - proof slatblinds of the type comprising a series of separate slats connected together by pivoted links which fold up when the blind is raised, and consists in forming the slats A of metal beaded at the edges A<2> and having wire insertions which form the pivot pins B ; or alternatively a short bead only is formed'to carry the pivots, and the central portion of the edges of the lath is formed into flanges A<3> which overlap when the blind is closed. Fig. 4 shows the blind lowered, but in open formation. The slats are pivoted to folding links C having stops C<2>, and are guided by blocks L running in guides E. The blind is closed by means of a lever Q which operates the clamping-bars M, or by the momentum of the fallen blind acting upon a stop M<2>. The beads or flanges are thus brought into the position shown in Fig. 6, the top one closing against a stop P.
