Page 292 - The scale is sometimes got rid of by " pickling," the iron being first dipped in dilute acid to remove the scale, and then washed in pure water. "If the trouble and expense were not a bar to its general adoption, this is the proper process for preparing wrought iron for paint, and it is exacted occasionally in very strict specifications. " But somewhat the same results may be obtained by allowing the ironwork to rust, and then scraping the scale off preparatory to painting. If some rust remains upon...

Page 7 - The deflection will vary from '3 to '5 inch. ' ' There is no difficulty in getting such iron, and higher qualities can be given if necessary, breaking strains of 30 to 35 cwt. being obtainable with judicious mixtures of the best kinds of iron ; and in testing such iron it will generally be found that some of the bars will endure as much as 38 cwt.
Page 94 - The road is to have a fall from the middle to the sides of about 1 ft. in 60, and ditches are to be dug on the field-side of the fences to a depth of a few inches below the level of the road." This system, which at one time threatened to supersede every other, is calculated to form a hard and impermeable crust on the surface, thus protecting the soft earth...

Page 201 - But if the abutments already exist or if for other reasons they have to be built, the curved roof, under these circumstances, in many cases, may be found cheaper and more suitable. Flat roofs are very common, especially in hot climates. The covering of these roofs rests upon beams placed in a horizontal position, or one that is nearly so. The slope given them is generally...

The broken metal is then to be carefully spread over it ; and as this operation is of great importance to the future quality of the road, the metal is not to be laid on in shovelfuls to the requisite depth, but to be scattered in shovelful after shovelful, till a depth of from 6 to 10 inches, according to the quality of the road, has been obtained.
Page 195 - Fig. 6685, but with longer rafters doubly trussed. The three forms just described are marked by the absence of vertical members, and for this reason the system is not a convenient one for hipped roofs, and for those roofs also where a longitudinal bracing between the principals is required in a vertical plane.
