On the ride to the Antelope viaduct he had noted a three-wire fence similar to this paralleling the right-of-way for several miles. Perhaps this was the same fence? If he only knew its direction! Dropping to the ground for a brief rest, Alex set his brains at recalling every bit of woods or plains lore he had ever heard or read of for the telling of direction.
A still further economy in cost of conductors was effected by the "Three-wire" invention, by the use of which the already diminished conductors could be still further reduced TO ONE-THIRD of this smaller size, and at the same time allow of the successful operation of the station with far better results than if it were operated exactly as at first conceived.
W. S. Andrews, detailed from the central staff, says: "The interior winding of the Sunbury station, including the running of two three-wire feeders the entire length of the building from back to front, the wiring up of the dynamos and switchboard and all instruments, together with bus-bars, etc. in fact, all labor and material used in the electrical wiring installation amounted to the sum of $90.
The Feeder and Three-wire systems are at this day used in all parts of the world, not only in central-station work, but in the installation and operation of isolated electric-light plants in large buildings. No sensible or efficient station manager or electric contractor would ever think of an installation made upon any other plan. Thus Mr.
On the far side it mounted the bench that flanked the bottoms and followed the crest of it, tying into the home corrals. Lighter three-wire fences marked the homestead lines within. The day that Evans led the men out on the calf round-up, the mule teams made their first trip across the plowed land with the drill. Harris and the girl sat their horses and watched the initial trip.
Our hauling of the other day must have done the mischief. "June 23. "We contrived to get the two ends of the large cable and to pick the short end up. The long end, leading us seaward, was next put round the drum, and a mile of it picked up; but then, fearing another tangle, the end was cut and buoyed, and we returned to grapple for the three-wire cable. All this is very tiresome for me.
Returning to the more specific subject of pioneer plants of importance, that at Brockton must be considered for a moment, chiefly for the reason that the city was the first in the world to possess an Edison station distributing current through an underground three-wire network of conductors the essentially modern contemporaneous practice, standard twenty-five years later.
'10 P.M. This second length of three-wire cable soon got into the same condition as its fellow i.e. came up twenty kinks an hour and after seven miles were in, parted on the pulley over the bows at one of the said kinks; during my watch again, but this time no earthly power could have saved it.
The parallel and three-wire systems in various groups, with or without accumulators as local reservoirs, are chiefly employed for incandescent lamps. The main conductors conveying the current from the dynamos are commonly of stout copper insulated with air like telegraph wires, or cables coated with india-rubber or gutta-percha, and buried underground or suspended overhead.
Then the Misses Avery, school-teachers, and elderly, looked at one another. "Did you ever?" whispered the oldest Miss Avery, and the others slowly shook their heads. Now, think! Did you ever see a rector jumping a three-wire fence, and running full speed across his front yard, in pursuit of a flying family? It may possibly have occurred, we have never seen it. Neither had the Misses Avery.
