F. CHANDLER Supervisor, in Charge of Maintenance of Way, Reciamalion and Welding, Pennsylvania Railroad It is not often that the o.y-acet_lene welder is calledupon to exercise his skill and ingenuity to the extent ofwelding together two piece.s of metal presenting a brokensurface of 330 square inches, and there are those who loudlyproclaim that a piece of work of such magnitude is beyondthe realm of possibility. Hence, a description of the workaccomplished so successfully at the Trenton, N, J, , shops of. The Shear Blade After Welding; Line of Fracture Shown onSurface of Weld the Pennsylvania Railroad, is of more than passing intere.st. Through the lack of care of a yard employee, engaged incutting up old metal, a piece of lJ4-in. by 4-in, steel wasfed into a shearing machine in such a way that a bolt inthe metal broke off the shear blade at the heel of the knife.This was caused by the twisting strain presented when thebolt was caught between the shear blades. The broken facewas 33 in. in height, 13 in, in thickness at the bottom and7 in. at the top. An examination of the broken parts showedthe metal to be of the highest quality of cast iron, there beingno flaws or sand holes, showing that the Ijreak was dueentirely to misuse. The shear has capacity for cutting 3!^-in, round bars, 3}^-m. flat bars, or 10-in, by lyi-m. flat bars, and is as large as cutting machines of this type are usuallymade. Immediate repair liecame a very urgent problem, as itwas impossiljle to order and secure a new
