A Home-Made Bulldozer. The need of a device to do riveting withwas felt at the Northern Pacific Railwayshops at St. Paul, Minnesota, at the timethe reinforcement of the 40,000-poundbox cars was taken up. All the old bodybolsters required a great many rivets inthe strengthening project then under Reading the Indicator Diagram. BY F. F. HEMENWAY. It is altogether fortunate that one doesnot have to write a book in order to enjoy BULLDOZER. and it being realized that hand-rivetingwould be too costly for serious considera-tion, Mr. John Hickey, superintendent ofmotive power, at once marshaled into linethe inventive forces of the plant, and ahome-made bulldozer and riveter, asshown in plan in our illustration, wasquickly gotten up to handle the problem. A cast-iron face plate, used for a form-ing block, was pressed into service tohold the dies. Two 8-inch freight air cyl-inders and one 14-inch passenger air cylin-der were then properly secured to the faceplate and piped to the air supply of 120pounds per square inch. So efficient wasthis affair that eighty J^-inch rivets perminute were driven in everyday practiceuntil the order was completed. The machine is now used as a bulldozert
