. American engineer . ts or studs that hold the smokebox front in place. A Xo. 22 Thor reversible airmachine, of the piston type motor, is used to drive it. .\ [)iniontransmits the power from the motor to a gear, which in turnis connected to the cutter proper Ijy means of a telescopi.; trans-mission rod and universal joints. The machine can be quickly attached and detached, reaches allflues without resetting, can be easily operated by one man, andis simple, effective and economical in its work. The working]iarts are of steel; the gear and pinion are completely enclosedand run in an oil bath, and destructive wear is practically elimi-nated. Interchangeabilily of parts is a strong feature of thedevice. The machine will cut 1-M 2 in., and 2l4 in. tubes,but a different size cutter is required for each size of tube. The cutter itself is shown in bigs. 3 and 4. It consists of fourparts, and turns upon an eccentric shaft, so placed tliat a quarterturn of the l)ody of the tool forces the knife out enough. *The writer begs to acknowledge thethe preparation of this article. able assistance of R. C. Morton Fig. 2—Application of Faessler Tube-Cutting Machine. to pierce the flue. One comi>lete revolution cuts the flue. Thecutter is then removed by reversing for a quarter turn andwithdrawing. It may be operated with a wrench, if heating the flues preparatory to flaring and welding onthe safe end a Ferguson flue welding furnace, furnished by theRailway Materials Company, Chicago, is used, and is illustratedin Figs. 5 and 6. It takes up a comparatively small amount offloor space, and maintains an ideal welding temperature, freefrom oxidation; the capacity is only limited by the skill of theoperator. It has a combustion chamber, in which combustionis started, the resulting temperature serving to break down theoil into a gas as it passes upward in the chamber. The flameis directed into the furnace and air is admitted for completecombustion by means of a s
