[Illustration: FIG. 34]
Before the day of change, a portion of the spikes were drawn from the inside of the rail to be moved, and spike set 3 in. inside of the rail. As a rule two spikes were drawn and the third left. At least every third spike was set for the new gauge, and in some cases every other one. There were several devices with which to set the spike. A small piece of iron 3 in. wide was common, and answered the purpose well. This had a handle, sometimes small, just large enough for the hand to clasp, while others had a handle long enough for a man to use it without stooping down. (See Figs. 35 and 36.) Another device is shown in Fig. 37, so arranged that the measurements were made from the head of the other rail. This was liked best, and, it is thought, gave the best results, as the moved rail was more likely to be in good line than when the measurements were taken from the flange. [Illustration: FIG. 35, FIG. 36 and FIG. 37] It was intended that great care should be taken in driving the spikes, that they were in the proper place, square with the rail, and left sticking up about an inch. The ties, of course, were all adzed down before the day of change. "Handspikes" were originally used to throw the rails, as were lining bars. We found, however, that small "cant hooks" were more easily handled |
