Note. This model also indicates the variable expansion and cut-off of 

 steam in the engine cylinder. 



1954. Drawing, on a scale of J-inch to 1 foot, of a patent 

 horizontal high-pressure condensing steam engine ; designed and 

 made by the Reading Iron Works Co. Reading Iron Works Co., 

 Limited, Reading. South Kensington Museum. 



Note. This drawing shows a side elevation of the engine and a through 

 plan. 



It represents an engine of 25 horse-power nominal ; having variable expan- 

 sion gear, fly wheel, governor, feed pump, and condenser. 



A similar engine was employed to drive a part of the British machinery in 

 motion at the Vienna Universal Exhibition for 1873. 



1955. Photographs, two, of a compound horizontal-cylinder 

 condensing steam engine. Constructed by the donors in 1873.

 other shows the fly-wheel, crank shaft, and governor motion, &c. 



The high-pressure cylinder is 14 inches in diameter. The low pressure 

 cylinder is 24 inches in diameter. The stroke of the piston is 2 feet 6 inches. 



This engine was employed in driving a portion of the British machinery in 

 motion at the Vienna Universal Exhibition of 1873.
