"That's a peach of an idea," declared Cub, jumping to his feet in his eagerness. "I've got two hundred and fifty feet of extra wire and some insulators on the boat and we can put up an aerial here without taking down the one on the Catwhisker. Then we can shift the radio outfit back and forth to the island and to the boat as we please." "Good!" exclaimed Hal. "I'm with you on that.
The next pole stood like a giant buried up to his chest and looked singularly helpless and footbound; and the last one I saw showed just its crossbar with three glassy, green insulators above the mountain of snow. The whole surface of this gigantic drift showed again that "exfoliated" appearance which I have described.
Finally twist the ends of each pair of short wires to the free ends of the insulators and then twist the free ends of the wires together. For the leading-in wire that goes to the lightning switch take two lengths of wire and twist one end of each one around the aerial wires and solder them there.
A. The spear of the desert man is either sharp pointed, spatulate pointed, or barbed. As a rule, a man carries a sheaf of half a dozen or more. B. In the Kimberley District the spears are of superior manufacture and much more deadly. The heads are made of quartz, or glass, or insulators from the telegraph line.
The aërial, of four wires, each thirty feet long and parallel, were attached equi-distant, and at each end to springy pieces of ash ten feet long, these being insulators in part and sustained by spiral spring cables, each divided by a glass insulator block, the extended cables being fastened to a maple tree and the house chimney.
The insulators are made either of glass or porcelain, and are of a peculiar form known as triple petticoat pattern. The loss on such lines, due to leakage between wires, is greater than that which takes place at the pole insulators, and is diminished by keeping the circuit wires as far apart as possible.
On all installations in basements and cellars or elsewhere where there is the slightest tendency to dampness, raise the motor off the floor on a suitable frame or stand and build around it on all sides of possible approach a low platform, using glass insulators as legs or standards to support it.
That was how he got on the committee. It was said that he had been a wonderful electrician at home, and he was eternally working with wires and insulators and Leyden jars; but, as he never seemed to get any further, or to have any results worth publishing he came at last to be regarded as a harmless crank, who had made science his hobby.
Next twist the ends of each wire to the rings of the ball insulators and then put the large withes on the middle of each of the end spreaders; fix the other withes on the spreaders so that they will be 27 inches apart and fasten the ball insulators to the eyes in the withes with the S-hooks.
He could more easily distinguish the dark glass insulators from the little sparrows that sometimes came to visit them upon the telegraph pole a quarter of a mile away than he could discriminate between the beans and the pie that sometimes lay together on his dinner plate.
