631,832. Horticultural frames. MILLWARD, G. H. May 7, 1947, No. 12285. [Class 20(1)] Relates to horticultural frames of the kind comprising a plurality of frames adapted to carry glazing and arranged in line to provide a continuous enclosure and consists in adapting the frames for stacking in superposed relationship and providing each with wheels or the equivalent and also with a rail adapted respectively to engage with the rail and with the wheels or equivalent of a frame below it so that any frame can be moved to or from a position in line by wheeling it over other frames. Each frame 10 comprises base members 11, inclined side members 12, cross members 14 of wide inverted V-form and intermediate member 15. The members are of angle section and are so fitted together that they form frames for the glazing. The apices of the members 14 are connected by a rail member 19 of inverted T- form to the underside of which is detachably secured, near each end, a depending bracket 24 in which a grooved wheel 25 is mounted. When stacked, the wheels 25 of one frame rest on the upstanding flange of the rail member 19 of the frame beneath, and to place the frames in line the uppermost is wheeled off the stack along the rail of the frame beneath it, which is then wheeled off the frame on which it in turn rests and over the previously disposed frame to its position in line therewith, and so on. The ends of the frames are flush and abut when the frames are in line. The frame members are preferably of light alloy, secured detachably together by bolts and set screws, and the glazing sheets are removable, so that the frame can be dismantled to occupy the least space.
