The first time the old piece was re-welded, and broke from the original cause frequency, five of them having broken inthe past year, besides the two that werewelded with oil. Nos. 4 and 8 are what we call the easyones, one reason being that 1-32 or 1-16inch in length is of slight consequence;another being that we are able to drivethe bottom of the jaw up with the pneu-matic hammer (which is a first-cousin tothe Cannon used in some shops), whichis a great persuader when an upwardblow is required. We will describe this weld in detail,which will serve to explain them all. asfar as the welding goes:. WELDING A LOCOMOTIVE FR.\ME IN PLACE WITHOUT TAKING DOWN—SOUTHERN PACIFIC SHOPS .\T OAKLAND. CAL. for welding frames, flues and other workhas been much discussed in local circles,and opinions for and against freely ex-pressed, so that we have deferred a de-scription until judgment had been passedby the great and celebrated judge of allevents—time. At least a partial decisionhas been handed down, as the first weld ofthis nature was made on engine No. 1304on November 11. 1899, as shown by theaccompanying sketches. This was an expansion weld, as theframe was blocked to prevent its goingendwise when heated and brought up to —weakness. We then put on a new piece,and that broke thirty days later, showinga poor weld and that we had a foreignsubstance between the pieces. We nextput on a new jaw, which gives every in-dication of being satisfactory after fivemonths service. Another weld of thesame ki
