This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1918 Excerpt: ...of the line, will have to be guyed as shown in Fig. 97, to keep them from being uprooted by the pull of the wire, and at curves the posts should slant outward or be guyed with wire to take the pull of the line. Fig. 98 shows how the wire should be secured to the end posts. Splices in the line should be avoided, if possible. If they cannot be avoided, make them as indicated in Fig. 99. The wire is run over a groove in the post, then over a nail in the side of the post, and is fastened securely with staples. Of course, the posts must be chamfered off as shown in Fig. 100, so that the grooved wheels of the car can go over the posts without bumping. It is safe to say that a boy can hardly draw the wire too taut. It will be sure to stretch and sag in time, but this is really an advantage, because the more it sags the less likely is it to break under heavy loads. Of course, a sagging line means that the car must do a lot of up and down hill traveling. However, at the outset, at least, it will be necessary to pull the wire very taut, much tauter than it can be done by hand. Some sort of a wire puller will have to be devised to stretch the wire at each post. A very simple contrivance is shown in Fig. 101. A lever is fashioned out of a strip of wood. In this lever a hole is cut, large enough for the nose of a pair of pliers to pass through quite freely but small enough to catch the handles of the pliers on the outspreading part. The wire is threaded through this hole, and then the pliers are inserted into the hole and made to grip the wire. The lower end of the lever may be rested against the post as shown and then, by pulling on the upper end, the wire may be drawn as taut as desired. The greater the pull on the lever, the tighter will be the grip on the wire, beca...
