Chemical experiments promise results alongthe lines of conserving steam boilers which can be expectedfrom no other source. SPRING BANDING MACHINE BY J. H. The spring shop of the Georgia Railroad at Augusta, equipped with a spring banding machine which has givensatisfactory service since its installation and may offer asuggestion to spring shop foremen who are in need of sucha device. The illustration shows in plan and elevation. A Machine for Applying Bands to Locomotive Sprlngi leakage are reduced. The water in the boiler is free fromsuspended matter, and better circulation and steaming isassured. Blowing out from both sides, should be the , as is often the case, more blowing is done from the leftthan the right side, the effects are shown by more staybolt how the spring Ijander is constructed. The machine wasmade from scrap and second hand material found aroundthe sliop and the total cost was $216 including laijor andwhat little material had to be oijtained from the storeroom.,\s .■liown, the two cylinders are firmly liolted to a rigid 164 RAILWAY MECHANICAL ENGINEER Vol. 92, Xo. 3 frame which is supported by braces from the lloor. Tliefulcrum pins are large and case-hardened to give greaterwearing qualities. The ratio of the long to the short leverarm is such that with 90 lb. air pressure in the cylinders, apowerful leverage is secured. The operation of the .machine,
