SPEEDER
One of the little things, that every engineer ought to have is a Motion counter or speeder. Of course, you can count the revolutions of your engine, but you frequently want to know the speed of the driven pulley, cylinder for instance: When you know the exact size of engine pulley and your cylinder pulley, and the exact speed of your engine, and there was no such thing as the slipping of drive belt, you could figure the speed of your cylinder, but by knowing this and then applying the speeder, you can determine the loss by comparing the figured speed with the actual speed shown by the speeder. If you have a good speeder you can make good use of it every day you run machinery. If you want one you want the best and there is nothing better than the one made by The Tabor Manufacturing Co., of Philadelphia, Pa. We use no other. You will see their advertisement in the American Thresherman.
SPARK ARRESTER
But one article in the entire list did I find to be sectional, and that was for a spark arrester. These inquiries were all without exception from the wooded country, that is, from a section where it is cheaper to burn wood than coal. There is nothing strange that parties running engines in these sections should ask for a spark arrester, as builders of this class of engines usually supply their engines with a "smoke stack", with little or no reference to safety from fire. This being recognized by some genius in one of our wooded states who has profited by it and has produced a "smoke stack" which is also a "spark arrester." This stack is a success in every sense of the word, and is made for any and all styles of farm and saw mill engines. It is made by the South Bend Spark Arrester Co., of South Bend, Indiana, and if you are running an engine and firing with wood or straw, don't run too much risk for the engineer usually comes in for a big share of the blame if a fire is started from the engine. And as the above company make a specialty of this particular article, you will get something reliable if you are in a section where you need it.
