The distinctive fea-ture of this valve is the center admissionof steam, which in a measure serves as a anced valve, as it has been demonstratedthat the valve can readily be removed byhand pressure with the valve stems dis-connected, and this is a very importantfeature, as it eliminates the internal fric-tion incident to the slide valve, and a con-sequent increase in the power of the en-gine. Some of the engines of this class, built 184 by the Baldwin Locomotive Works, withthe slide vaves, have not been in servicemore than one year and have renderedmost excellent service, and their perform-ance thus far has not indicated that theslightest change from the original planswould be desirable. LOCOMOTIVE ENGINEERING slide valve. The steam from the steamchest enters between the valve heads. Ad-mission to the front steam port is openedwhen the valve is moving forward, and tothe back port when it is moving valves and eccentrics have, of course,to be set to meet these May, 1900. they can be moved around the yard withno more trouble or work than a sectionmans push car when loaded. This der-rick has a long air cylinder fastened alongthe boom, which lifts a half-ton bucketwith ease. To balance the bucket of coalso the derrick will not tip over, a heavy airreservoir of cast iron is set on the otherside of the center and swings around withthe boom. The reservoir has an air hoseconnection with the air supply pipe run-ning through the coal yard. Movable derricks are about the onlymachine that will handle coal from a longbin on the ground, and these little ma-chines do the work at a good speed withsmall expense.
