Abstract: 710. Chase, L. H. Jan. 9. [Cognate Applications, 2208/12 and 10,458/12.] Seed and plant protectors.-Sheets of glass, slate, or other material are held in position to form frames or lights for horticultural and other purposes by means of transverse members having end hooks or recesses to engage the lower edges of the glass &c. and intermediate portions bent upwards inside or outside of the frame, means being provided for engaging the glass sheets at other points so as to produce a stable structure, and also for closing the ends of the frames, when required, and for supporting vertical glass sheets at the sides of rows of plants. Fig. 1 shows a hooked wire or strip c bent upwards inside the frame and engaged by a spring or other hook d passing through a wooden block b. The glass plates a fit into grooves in the block b, and the whole structure is tightened up by screwing up a nut e on the hook d. In a modification, the wire c is looped or coiled at the centre so as to yield or spring more readily to allow of insertion and removal of the plates a. In this form, the hook d is not screw-threaded, but is provided with a handle and passed through a slot in the block b. In another modification, the wire c is outside the frame and is connected to the block b by an adjustable or spring strut. In another form, two outside spring wires are used, each consisting of two vertical parts connected by an approximately horizontal part bearing directly on the upper edges of the glass plates, which are held apart by pieces of leather &c. threaded on the wires. In another form, a single looped or other outside wire bears directly on a grooved block b. In other modifications, the hook d is replaced by a spring U-shaped or like piece passing through a slot or holes in the block b and bent to form a handle. In other modifications, the block b is dispensed with and the wire c engages a bent wire m, Fig. 14, placed between the upper edges of the plates a and bent at its ends so as to rest upon them. The wire m may be bent to form handles of various shapes. The ends of the frames may be closed by vertical plates p held in position by hooked wires o fastened to the wire m &c., or by bent wires pushed vertically into the soil, or by bent wires q provided with anchoring- members r. The bent wires may be used to support sheets of glass vertically at the sides of rows of plants. The wire q may be used to connect the tops of the two plates p. The ends of the supporting-members may be forked to engage the plates at several points. One of the plates a may be of glass and the other of slate &c. The wires may be coated with lead &c. or may be flattened to engage the plates, or may have flat pieces or grooved blocks fastened to them. The grooved block b may be replaced by a W-shaped piece of metal. It may extend for the whole length of the frame; or two or more blocks and wires may be used. The frame may comprise more than two glass plates. For two side plates and a top plate, two hooks d and blocks b would be used, and the wire c would have two angular points. Specification 2346/11 is referred to.
