There is no question as to great results from this device as afuel economizer. Then again its practical utility in divertingthe steam pump exhaust from the front end into the tender issimply getting rid of a nuisance at no expense, and putting itwhere it is of real benefit, in addition to the great saving in fuel. A patent has been applied for on this device and already quitea number of roads are arranging to use it. It certainly appearsto be one of those things which, without adding a complication ofparts, reduces the waste of fuel in one direction to a minimum. =1 j&.. The Barnes Feed-Water Heater.—Fie. 2. AND RAILROAD JOURNAL. 143 The Pyle-National Electric Headlight. The manufacture of electric headlights must, in even a greaterdegree than the makers of other first-class machinery, combine intheir apparatus, simplicity, reliability, efficiency and the minimumof bulk, cost and maintenance. Many railroad officers are injavor of electric headlights, but are looking for a simple and lessexpensive mechanism than has vet been offered them. The improved electric headlight patented by Mr. Geo. C. Pyle,and placed on the market by the Pyle-National Electric HeadlightCompany, of Chicago, presents these desirable features to a greaterdegree than any headlight in the market. Its general appearanceand special featuresare shown in the ac-companying engrav-ings, in which Fig. 1 isa section through thedynamo and motor,Fig. 2 is an exteriorview, Figs.
