945,090. Drain channels in louvre window frames. A. SUMMERSGILL, and J. F. SUMMERSGILL. Feb. 23, 1960 [March 26, 1959; July 31, 1959], Nos. 10554/59 and 26289/59. Heading E1J. A louvre window in which the slats 13 Fig. 4 are pivotally supported between two window frame members or mullions 10 and the faces of these mullions adjacent the edges 12a of the slats or of the end clips 12 mounting the slats have a groove or grooves 14 to direct water to the outside of the window which is/are covered by the slats e.g. with a sliding fit clearance, when these latter are closed, and the grooves 3 Fig. 2 are directed around as at 5 Fig 2, extend outwardly as at 4 Fig. 1, at the pivots 2, or through the pivots, as at 4 Fig. 3. The grooves 3 may be set at a slight angle out of the vertical and stepped from slat to slat to correspond with the angular disposition of the closed slats. Where these latter overlap an interfitting bead and groove 13a, 13b Fig. 11 are provided. The pivoted supports 2 include a dust-excluding washer (Figs. 8, 9 not shown) and deep or wide bearings for the pivots are formed in the members or mullions 10. The grooves 3 may take the form of gutter-like channels of various shapes indicated in Figs. 15-19 (not shown). The grooves may be in the edges of the slats or of the clips supporting the slats or in the members or mullions 11 and the edges of the slats or clips, the grooves in the one registering with the grooves in the other when the slats are closed.
