Patent #224,481
The annexed engraving represents a new design of vertical steam engine and boiler, which are now being manufactured by L. P. Thompson, at the Bordentown Foundry and Machine Works, Bordentown, N. J. Some of the peculiarities of this engine are its simplicity and great strength. The pedestal column or frame, cylinder and steam chest, are cast in one piece, which admits of less iron being used than where they are farther apart, The guides being placed above instead of below the cylinder admits of shortening the length of the column, which makes the engine less top-heavy, and when mnning fast there is less tendency to vibrate. The guides are cast solid with the cylinder head and there is no tendency to get out of line. By placing the guides and cross head above the cylinder a long connecting rod is secured, which is over five times the length of the stroke; by this arrangement the wear-and-tear of the guides and other parts is greatly reduced on account of the small angularity of the connecting rod.
By thus reducing the friction more power may be developed with the same expenditure of steam. The steam chest is large, the ports well proportioned, causing the least possible loss from friction of the steam in contracted passages, or by back pressure in the exhaust. The line of steam is directly central throughout the engine.
The piston rod, valve stem, cross beam, connecting rod, and the other working parts, are of steel and the best gun metal. The boiler attached to this engine is of peculiar construction, and calculated to give the most economical results. As shown in the engraving, this engine and boiler may be quickly transported, and put in operation wherever power may be required. It is also furnished with all the modern appliances. The engines are detached from the boiler, and for use in steam yachts or propellers, have a link motion attached. It is desirable for this purpose, on account of the small floor space required. The 6" x 6" engine, for instance, complete as a yacht engine, weighs but 200 pounds, and occupies a floor space of 14"xl4". This size engine is claimed to resist the severest test of a ten horse power boiler, and driving a 33'-blade propeller wheel entirely submerged.
