Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1908 edition. Excerpt: ...as shown by Fig. 92. Now measure forward on the guides, from the head-end dead center, a distance in inches equal to the point of cut-off of main steam valve and make a mark R. (This distance is given in inches by the engine builder.) Place the engine on the forward stroke until the mark on the crosshead coincides with line R, as in Fig. 92, the head-end steam valve should come line and line with the port. Measure forward again from the head-end dead center to the point of compression or closure of the exhaust valve, and make another mark 0 on the guides. When the engine is placed on the forward stroke so that the crosshead mark coincides with mark 0, the crank-end exhaust valve should come line and line. Make similar marks r and o on the guides, measuring back from the crank-end dead center, for the points of main valve cut-off and compression on the return stroke, as shown above Fig. 92, and by placing the engine on the return stroke, check to see that the other valves come line and line. On all main steam-and exhaust-valve stems will be found an encircling mark like that at X, Fig. 91. This trams, by a tram of known length, with a mark on the cylinder casing when the valves are line and line, thus making it unnecessary to remove the valve covers. The auxiliary or cut-off valves yet remain to be set. Measure forward on the guides and locate point Q, the point of cut-off of the auxiliary valve as furnished by the builders; also measure back from the crankend center and locate the similar point q for the return stroke. Adjust link I, Fig. 82, and link K, Fig. 85, to give the proper stroke of the valve, measuring the stroke as before by the mark x on the stem. Then turn the engine forward until the crosshead mark coincides with mark Q and set the...show more
