To quickly assess the difficulty of the text, read a short excerpt:
=Splices. = As the upper and lower chords have to be made in severallengths, securely fastened to each other, and, in order to weaken thebuilt beam as little as possible, it is necessary to adopt some formof splicing whereby the greatest amount of tensional strength may beretained in the chord with the least amount of cutting, and yet have asecure joint. Such a splice is shown in Pl. II, Fig. 4, and below is atable from Vose's Hand-book, giving reliable dimensions. Span. A C B B C D Feet. F...eet. Inches. Feet. 50 1. 00 1-1/2 1. 50 100 1. 25 2 2. 00 150 1. 75 2-1/2 2. 25 200 2. 00 3 2. 75 This manner of splicing requires the back of the splice block to belet into the chord stick, against which it lies, about 3/4 of an inch. To show how the various Engineers differ, as to their estimates of thesizes of the several parts of bridges, I subjoin two Tables--one byProf. G. L. Vose, a well known Engineer, and one by Jno. C. Trautwine, an Engineer of note also--and I would premise that a bridge builtaccording to either would be amply strong.
