Fig. 220.—Another Wide Farm Gate.
The illustrations, [figures 219] and [220], show two forms of gates used on the island of Jamaica. These gates are twenty-one feet long, each, and cannot possibly sag, even if any number of small boys swing on them. In gate [figure 220] the main post is nine by six inches; the bars—marked 2, 3, 5 and 7—are let in the wood three inches on the upper side and one and a half inches on the lower. The tenons, indicated by the dotted lines, go entirely through the posts, and are fastened with pins. Brace 6 is attached to the upper bar eighteen inches beyond the center, F; D is a stout fence wire fastened by a screw nut at E; the wire, B, is held tightly by the screw hook, A; the iron band, 9, is an inch thick and is bolted to the post. It works on a pivot one and a quarter inches in diameter, and which turns on a flat piece of iron at the bottom of a piece of a one and a half inch iron pipe, which is soldered with molten lead in the stone, 10. Only hard wood is used in the construction. In the gate shown in [figure 219], the construction differs from the one just described in that it has a light chain fastened in the shackle, C, and is screwed firmly at A. It is attached to the post, H, by a pivot, as seen in our illustration.
