Locomotive engineering : a practical journal of railway motive power and rolling stock . works, are notable for their graceful forms.While the reduction of weight has beencarried as far as possible, no expense onwork or on material has been spared tomake the engine efficient and durable.The valve motion gives a very good tions. The hangers connect with linksuspension pins about 8 inches long, andthe upper rocker pins are about the samelength between head and washer. Theoutside of the tires is polished. The frames are wonderfully substantial, considering the lightening process thatthe engine has undergone; the part thatextends from the front joint to the frontof the cylinder is 7 inches deep. Theguides are of the double-bar style, andare secured in front to lugs cast on theback cylinder head, and in the back bycross-braces i;4x8jij inches. The firebox is set above the frame andis held up by swinging hangers on eachside, with expansion pads at the front cor-ners, and a single pad extending nearlythe whole breadth at the back of the fire-box above the foot plate. The cylinder. LAKE SHORE TEN-WHEEL PASSENGER ENGINE. to a total weight of 118, 000 pounds, whichis about the same as the weight of theold engines. The work was, however, carried out successfully, and this enginehas 1 inch greater diameter of cylinder, 2 inches more diameter of boiler and has263 square feet more heating surface thanthe old type. When people proceed todesign a new engine, it very often happensthat the real weight comes out very dif-ferently from what was calculated upon;but this engine was an exception, forwhen put upon the scales in working or-der, it came within a few hundred poundsof the specified weight. This displayedunusually skillful designing. It was de-termined from the first that the processof lightening the whole engine should notreduce the strength of essential parts—like frame, rods, axles, etc. The reduc-tion of weight was effected to a greatextent by improved forms, and the useof s
