Miami Conservancy Bulletin PDF Download

Excerpt from The Miami Conservancy Bulletin, Vol. 3: March, 1921 It is interesting to note that the use of the hollow head, as in the Harshman rail, was also to save metal, the amount saved being about 10 per cent. The metal was saved at some excess labor cost for rolling the rail head hollow, indicating a relatively low labor cost at this period of manufacture. It will be understood that the historical develop ment shown in Fig. 283, gives dates of introduction of the several shapes. In actual use, of course, the older forms survived many years (as in the Harsh man siding), gradually disappearing, and finally be coming extinct.
