. Amerikanischer Ingenieur und Eisenbahn-Zeitschrift. Trument wurde entwickelt, um diese Anforderung zu erfüllen, und es wurde getan, ohne die acht beweglichen Teile zu erhöhen. Die Trommelbleistift-Bewegung ist die gleiche wie die zuvor von dieser Firma verwendet, aber die Fläche des Kolbens wurde von einer Hälfte auf ein Viertel asquare Zoll reduziert, die die Verwendung einer kleinen Größe von Draht in der Pring erlaubt. Anstatt komprimiert zu werden, ist diese Feder in Aktion verlängert, die dazu neigt, die Bewegung in einer directline zu bringen, wodurch Krämpfe und übermäßige Reibung vermieden werden. Der Penciloperiert in einer Weise, die direkt dem von entgegengesetzt ist

. American engineer and railroad journal . trument was developed to meet thisrequirement and it has been done without increasing theveight of the moving parts. The drum pencil motion is thesame as that previously used by this company, but the area ofthe piston has been reduced from one-half to one-quarter of asquare inch which permits of using a small size of wire in thespring. Instead of being compressed, this spring is elongatedin action, which tends toward bringing the motion in a directline, avoiding cramping and excessive friction. The penciloperates in a way directly opposite to that of inside springindicators and the atmospheric line is at the top of the drum.Instead of being at the bottom, the cylinder connection is atthe side of the instrument and an angle cock is used to mountit, which brings the steam pressure on top of the piston. It iseasy to remove the cylinder for cleaning or examination, with-out interfering with other parts and from the engraving itwill be noticed that the end of the cylinder has no connection.

The drawing shows how the spring isremoved from the hot steam and is not liable to change of ten-sion or to deterioration. Automatic stokers for locomotives were highly spoken ofby Mr. J. F. Walsh, superintendent motive power of the Chesa-peake & Ohio Railroad, and Mr. S. M. Vauclain, of the Bald-win Locomotive Works, at the March meeting of the NewYork Railroad Club. Both of these gentlemen considered theexperience of the past few years sufficient to indicate a prom-ising future for stokers, and they thought that the devicewould make very rapid progress in the near future. What is the true principle of organization in a democraticcommunity? Getting others to do what you want done whilethey are doing what they themselves wish to do.—Mr. Fren-year, before the Electric Club
