592,784. Sectional glasshouses etc; window frames. MUSGROVE & GREEN, Ltd., and GREEN, D. A. June 4, 1945, No. 13941. [Classes 20(i) and 20(iii)] [Also in Group XXV] Glasshouses, forcing frames, and the like are built of a number of metal sections assembled by U-shaped members of wire or sheet metal engaging apertures in the sections and having wedges driven between their limbs, each U-shaped member having its limbs bent at right angles to the plane of the U to form the necessary abutment. A greenhouse frame may comprise angle section horizontals a, b, e, flanged channel section uprights and roof members c, d<1>, k, with gusset plates g at the intersections all secured by the U-shaped members e, Fig. 4, passing through slots such as a<1>, b<1>, c<2> in the sections, and wedges f. Window frames comprising upright channels h and horizontals i secured together by the same means are hung at various heights by the projecting ends of the members i on clips c<3> on the uprights c of the frame. Sheets of glass are located by the channels h and rest on lugs h<1> pressed from a flange in these channels, the sheets overlapping. The ends of the house are likewise glazed, additional triangular fillets j<1> here being required, the sides of the greenhouse being slightly inclined to the vertical. The roofing glass is slid between opposed flanges of members d<1> and supplementary members d<2> secured thereto.
