Excerpt from Safety-Valves The writer, in presenting these remarks to engineers, does not pretend to o¿er much that is original, but has aimed to gather what is valuable from the great mass of material to be found in scientific periodicals and in publica tions that are not generally accessible. An endeavor has been made to systematize the treatment of the subject, and to give such varied solutions of the problems that arise in proportioning the parts of safety-valves as to render them plain to those who have only an elementary education. The importance of having the general principles of safety-valves understood by those who are charged with the care of steam machinery cannot well be over estimated. With a safety-valve that is in real ity all which its name implies, a large propor tion of the risks incident to the use of boilers will be avoided, while on the other hand, a safety-valve that is only such in name is one of the readiest assistants to a disastrous boiler explosion.
