illustrates the end elevation and plan of a draught screen which is constructed of a light framework and covered with baize or American cloth. The reversible double-folding hinge would answer admirably for such a screen. Cases occur, however, where it is desired to hinge a screen to be used for an invalid's bedside, and it is then important that all draught should be excluded through the jointed edges. The double reversible hinge will not fulfil these conditions, and the following method is therefore adopted.
In the plan, Fig. , A and B, two laths of hardwood (beech, birch or mahogany answer splendidly) are shown. They are made the same length and the same width as the edges of the screen, the corners being slightly rounded away.
A double-folding, draught-proof hinge is then made as follows: Procure good fine webbing, about 11⁄4 in. wide, and the necessary large-headed tacks. Lay the laths side by side as shown in , and proceed to web them as shown. Commence with the web under the lath A; bring it between the laths and over B; now take it round the left-hand edge of B, and round the back and between the laths and over A, continuing this method of wrapping the laths until the lower end is reached, and then fastening the webbing as indicated by the dotted lines which represent the tacks. This self-contained hinge is then fixed to the edges of the screen by boring suitable holes through the laths and using countersunk screws. This is a cheap and efficient method of overcoming the difficulty. A similar method is used for the household clothes horse.
