The middle cross rail which carries the swing is 6 in. in diameter and 8 ft. 6 in. long. A seating is formed on the plates, and a shallow one upon the rails, which are secured with long 3/4-in. diameter bolts and nuts; the latter are let into the posts at a distance of 8 in. from the top, as shown in [Fig. 105], which is a cross section through the plate near the middle rail. Short struts may also be fixed between the posts and cross rail, as in [Fig. 105]; they are not shown in [Fig. 101]. A floor is formed of saplings, connected to the sills, thus preventing them from spreading. The trellis-work, both on the roof and sides, is now fixed. This is composed of 1¾-in. and 2-in. twigs.
The swing hooks ([Fig. 106]) pass right through the rails, and are secured with nuts and washers. Collars should be forged on the shanks to prevent the hooks being drawn too far into the wood when screwing up the nuts. The shank is screwed ¾-in. Whitworth pitch thread, and the hook is 1¼ in. in diameter at the thickest part. The hemp rope is spliced around galvanised iron thimbles (see [Fig. 107]), which take the wear on the hooks. The rope is usually secured to the seat by simply knotting the ends.
Should the swing be used for very young children, a seat provided with a fence will be necessary, as shown at [Figs. 108] and [109], which are front and end views respectively. The back rail and the two side rails are fixed to the seat with the balusters; but the front rail is tenoned to open-ended mortices in the side rails, and thus made to hinge, to facilitate the lifting of the children on and off the seat, the rail being secured in its closed position with a brass pin and retaining chain. The suspending rope in this case is passed through the end rails and knotted to the seat. [Fig. 110] shows the rope passed around and whipped to an eyelet.
