Page 39 - J inches wide, heated uniformly to a low cherry red, and cooled in water of 82° Fahrenheit, must stand bending in a press to a curve of which the inner radius is one and a half times the thickness of the plates tested.
Page 38 - We want a perfectly coherent and definitely carburized bloom or ingot of which the rolls have only to alter the form in order to make plates with qualities as regular and precise as those of copper and gun metal, and we look to the manufacturers for it.
Page 39 - The ductility of every plate is to be ascertained by the application of one or both of these tests to the shearings, or by bending them cold by the hammer on the contractor's premises, and at hi? expense. 5. All plates to be free from lamination and injurious surface defects.
Page 39 - Strips cut from the plate, angle, or bulb steel, to be heated to a low cherry red, and cooled in water of 82° F., must stand bending double round a curve of which the diameter is not more than three times the thickness of the plate tested. UNDERWRITERS.
Page 110 - ... thick, being very badly indented between the frames. This plate we decided to remove, and started doing so at 7 PM on the 7th instant. The removal occupied twenty-four hours, as all our tools broke in the work, and a new set had to be specially made to stand the steel. The plate looked so bad that it was doubtful whether it was worth while spending any time over it, however we decided to 'give it a fair trial, and it was...
Page 39 - Strips cut lengthwise or crosswise of the plate, and also angle and bulb steel, to have an ultimate tensile strength of not less than 27 and not exceeding 31 tons per square inch of section, with an elongation corresponding to 20 per cent. on a length of 8 inches before fracture. Strips cut from the plate, angle, or bulb steel, to be heated to a low cherry red, and cooled in water of 82°...
Page 115 - A number of frames were set back by the force of the blow, the bulkhead was bulged and the plate was corrugated, and yet there did not appear one crack anywhere. We would, however, require better tools than we have at present if we are to have anything further of this nature, as the steel proves very difficult to work.
Page 115 - A point calling for special notice is the large number of separate compartments formed by water-tight bulkheads, each extending to the main deck. The largest of these compartments are only about 60 ft. long; and supposing that, from collision or other cause, one of these was filled with water, the trim of the vessel would not be materially affected. With a view of giving still further safety in the event of collision or stranding, the boilers, as shown in Figs.

We will with pleasure insert any letters likely to benefit our readers, either from their intrinsic value or as being calculated to promote such discussion as will elicit facts, valuable from their being the result of practical experience.
Page 232 - ... course safe and practicable, this position and her safety depend entirely on the rudder not being disabled. The strains at such times brought on the chains and rods are very severe, and unless the material and workmanship be exceptionally good, every blow from a heavy sea becomes a trying ordeal, for if anything should give way nothing can prevent the vessel from falling off into the trough of the sea, and being placed in imminent peril. This has very recently been shown to arise even in one...
