594,773. Greenhouses. STANWORTH, J., STANWORTH, L., and STANWORTH, S. Jan. 14, 1945, No. 13542/44. [Class 20(i)] A glasshouse comprises a framework of rods on which are fixed brackets by which the sheets of glass, &c., which form the roof and walls are removably supported, the lower portions of the wall sheets resting in recesses between projections on the brackets and some or all of the brackets at the top of the sheets being provided with holders for retaining the sheets in a closed or more or less open position. End frame members are composed of uprights A bent to form sloping roof members A<3> to which are attached other uprights A<1> joined to the uprights A by transverse members A2. Intermediate frame members consist of uprights F bent to form roof members Fl and having attached angled rods F<2> which support a shelf G. Hooked tie rods between opposite rods A<1> and between opposite rods F<2> may be used as gauges in the erection of the frames and may be left in position as struts after erection. Tie rods may also be formed with cranked ends to drop into holes in the brackets. Bottom brackets B have holes for fixing to a foundation K or pegging to the ground and suitable projections for locating the lower edges of the glass sheets. Intermediate brackets C, Fig. 8, have projections c<2>, c<4> for holding the spring clips J, projections c<1>, c<3> for holding the lower edges of the sheets above, and have their edges bent over to form flanges which are bent to embrace the straps. Two additional straps may join the tubes at each side of the ladder. The treads are formed with an embossed pattern to prevent the feet slipping. Each of the upper ends of the tube forming the stay 10 is fixed in a bracket 13 pivoted at 17 to the rear tube of the corresponding side frame. The edge 16a of each bracket is shaped to engage round its rear tube, to prevent the stay from opening too far. The ladder may narrow slightly from top to bottom. In a modification, the stay 10 is combined with holes c<6> for the cranked ends of tie rods. Top brackets D, Fig. 1, have similar projections for holding the springs J and incorporate strips of metal which may be bent over the lower edges of roof sheets to hold them in position. Alternatively these sheets may be held by spring clips embracing the uprights above the brackets D. Ridge brackets E have projections for holding the upper edges of the roof sheets and holes for fixing them together or to a support such as the beam M. As shown in Fig. 8 the brackets are welded to the uprights, but in a modification they are clamped on with set screws and the springs J are held by a nut and washer on the set screw. Using half the framework shown in Fig. 1 a glasshouse may be constructed as a lean-to.
