509,631. Horticultural frames. SMITHSON, W. Feb. 28, 1938, No. 6304. [Class 20 (i)] A horticultural frame of the kind in which the grooves of the glazing bars are of sufficient width to receive superposed sheets, has these grooves open ended, so that a sheet may be readily slid out of position and inserted temporarily above a sheet in another section to preserve it from damage. In one form, as shown in Fig. 2, separate grooves 22, 23 are provided in each glazing bar 19, and to the upper surfaces of these are secured the upper and lower longitudinal frame bars, 14 and 16 respectively ; removable stops 26 are provided to retain the sheet 24 in the grooves. In another form, a single groove is provided in each glazing bar of sufficient depth to receive superposed sheets. Frames comprising these open-ended grooved glazing bars connected by longitudinals may be hinged together at their upper edge at 32, the frames being retained in the required positions by end straps 34, Fig. 1. More than two frames may be hinged together to form a multi-sided figure and the frames may be of unequal dimensions. The hinges may be replaced by brackets in which case the frames are not collapsable.
