The display of the Lane & Bodley Company, of Cincinnati, O., at the Exposition consists of three horizontal Corliss engines—a simple, a tandem compound, and a cross or twin compound. The cross compound represents their latest design. The girder is of box section and with the main box and slide support is in one casting. The slides are bored to a large radius giving a very large wearing surface for the cross-head on the slides. The design is remarkable for stiffness and has been developed to meet all the requirements of electrical engineering. The cylinders are made without the usual square corners, eliminating this unnecessary finish. The bonnets and caps are made with round flanges and the legs or pedestals under the cylinder, usually detachable, are cast with it. The steam chamber in the top of the cylinder is unusually large. The engine has sixteen by thirty-one by forty-two inch cylinders, and is designed to run at seventy revolutions per minute. The main shaft is nearly eight inches in diameter. The steam pipe is five inches in diameter, and the exhaust pipe to the condenser measures ten inches. The steam ports in the high-pressure cylinders are seven-eighth inches, and the exhaust ports 1 7/16 inches wide, and both are sixteen inches long. The steam and exhaust ports of the low pressure cylinders are respectively 1 15/16 and two and a quarter inches wide and thirty inches long. The crank pins are 4 7/16 inches in diameter and five inches long.
The tandem engine, of which an illustration is shown, is made from the old patterns. The cylinders are sixteen inches in diameter, high pressure, twenty-nine inches low pressure, and forty-two inches stroke, and are attached to an especially heavy girder frame. The main bearing of the shaft is 10 15/16 inches in diameter. This engine is furnished with the low-pressure cylinder next to the girder, and a very neat trunk connection between the two cylinders. The receiver on both the tandem and the cross compound engines is arranged below the floor. The third engine is a simple engine, having a cylinder eighteen inches in diameter and of forty-two inch stroke. The girder is made with a ribbed section forming three sides of a box. The governor on this engine is of the Hartnell type, well known in connection with this engine, and which has proven very successful in delicate regulation and durability. The engines are splendid specimens of design, having neat lines, and are evidently built for hard service. Their proportions are such as will adapt them successfully to electric lighting and railroad service. |
