14 MARINE REVIEW. March, 1922 PATE I EES A LL EE TE EE LE EE “‘A Failure is Never a Failure, Unless You Fail to Use It as An Experience, and a Stepping Stone to Success.”’ There have been some wonderful “Experiences” with our ships. In some cases they were used as experiences, and in other cases—sad to say—they were used as failures. When the Shipowner burned his coal on those Noah grate bars (because they were cheap) he economized expensively. The “pocket nerve” is ever sensitive, and if you, Mr. Shipowner, will burn your coal on SEMI-STEEL homas Wiggling--Shaking--Dumping GRATE BARS of 36,000 pounds tensile strength the Heat Devils they will liberate, through perfect combustion will form a great economy chorus. We are anxious to enlist further in the service of the Ship people—and help save coal. PUT IT UP TO THOMAS Easily installed — For use with either Natural, Induced or Forced Draft — Eliminate the cleaning period—Avoid mishaps and shutdowns—Reduce the fireman’s labor—Pay for themselves in a few weeks’ use—Fool-proof. WIGGLE out the fine ash without increasing spaces between the bars to waste fuel or seriously rupture fuel bed to get it into holes and pockets. SHAKE out small rock, slate and clinker by giving lever little longer stroke, slipping any size crack between each bar that is necessary. DUMP out all refuse. by giving lever full strokes, throwing the bars at an angle of 85 degrees. MAE THOMAS GRATE BAR CO. Netural BIRMINGHAM, ALA.
