Excerpt from The Operative Mechanic, and British Machinist: Being a Practical Display of the Manufactories and Mechanical Arts of the United Kingdom
He recommends the dimensions of the bars meant to form the upper surface of a railway, calculated to carry locomo tive engines of seven or eight tons, and waggons of three or four tons weight each, to be fifteen or sixteen feet long, two and aquarter inches broad, and half to five-eighths of an inch thick. At every eighteen inches or two feet of the length of this surface-plate, a tcnon is firmly welded or riveted or otherwise attached to the under side, taking care in this operation to leave the up surface of the plate even as before. These tenons have ho es through them in the transverse direction of the ham, to take a pin or rivet of from abouts quarter to half an inch in diameter; and at each extremity of the plate, a tenon is fixed on by welding, bavin previously cut off a piece of about two inches long, and 0 half the breadth of the bar, from the opposite ends of the bar or plate, and at the opposite angles, so that when two bars, so primed, are brought to join at the ends, the joint is what 18 nominated a half-lap, or scarfed joint.
