SAVINGS EFFECTED It is impossible to give an exact statement of the totalsaving made on car equipment by the company during theyear 1912. In some instances the welder has added yearsto the life of certain equipment, owing to its being an oldtype and the impossibility of renewing certain parts thatare no longer manufactured. Another important thing isthe saving in time. A truck or motor frame can be re-moved from a car, repaired and replaced in a few hours,whereas if a new part was to be installed it might meanthat the car would have to remain out of service for anumber of days. It is even possible to do certain minor. San Francisco Shops—Brakehead with Worn Socket Beforeand After Repair repairs with the apparatus in place. For instance, con-troller backs are welded in place, and even the connectionsare not removed. The shop report for nine months shows that 234 caraxles, twenty-nine truck frames, forty-seven compressorarmature shafts, ninety-eight motor armature shafts and630 gear cases have been welded, besides the many otherparts given in the appended list. If it should be assumed to have been necessary to replaceeach of the pieces just mentioned with a new part, thenthe net saving on these parts for nine months would havebeen $10, If to this sum is added the saving madeon the other pieces given in the list, the value of the welderas a factor in the economy of the shop is evident. The accompanying illustrations show how some of thework is done. The view of the interior of a motor casingshows a GE-90 motor frame on which the axle-bearinghousings have become wo
