THE CIVIL ENGINEER AND ARCHITECT'S JOURNAL. 



[February, 



at measured mile = miles per hour. Although the Rondine and Antelope 

 are of the same capacity, they differ in the construction of their motive 

 powers : the former, the Rondine, having heam engines, the Antelope, oscillat- 

 ing or vibrating cylinder engines, both of the power of 40 horses. Cylinders 

 26J in, diameter, stroke, 2.0, and 34 strokes per minute. The beam engines are 

 of the usual construction, as designed by Boulton and Watt in 1818. The 

 various parts are reduced in strength as experience and improved manufac- 

 ture dictates ; we perceive they have in this case abolished the headstock 

 framing, substituting pillars and an entablature, secured longitudinally by 

 strong deck or paddle beams, they are continued through the side, support- 

 ing the ends of the paddle shafts, so that they have no connexion with the 

 spring-beam or frame of the paddle-boxes, thereby preventing tremulous 

 motion. This arrangement is by no means new, yet greatly to be recommended 

 and will shortly be applied to a vessel of 300 horse power. The oscillating 

 engines of the Antelope, in arrangment, are similar to those of the Virago, 

 published in the Journal, June 1841, Vol. IV., each engine having its 

 air-pump and condenser — the former worked by a small beam connected with 

 the cranked intermediate shaft. It may be mentioned as an argument in 

 favour of oscillating engines (of modeiat? power), that in these cases there is 

 a saving of rive feet in length of engine-room, and in weight of about six 

 tons. These engines occupy a space of 10 feet athwart, and five feet fore 

 and aft. The small amount of the former arises from the combination of 

 the parts, and must be advantageous in its application to vessels of narrow 

 beam. The boilers in both cases are of the common flue kind, weighing 7^ 

 tons; or, with its apparatus and water (the latter five tons), 14 i tons; the 

 engines weigh 13 tons, making a total of 27£ tons complete. Both these 

 vessels are fitted with a disengaging apparatus for the paddle wheels, so that 

 they may be connected with, or detached from, the engines at pleasure, 

 which, as well as the engines of the Antelope are the subjects of a patent 

 lately granted to Mr. James Brown, of the firm of Boulton, Watt, and Co. 



The Great Northern Steam-Ship.— This magnificent ship arrived off 

 Blackwall at the beginning of last month, and has since taken up a berth in 

 the East India Import Dock. The Great Northern has been built within the 

 last 12 months at Londonderry, by Captain Coppin, of that place. She is 

 a fine specimen of naval architecture. She is fitted with Mr. F. P. Smith's 

 patent screw propeller. Her dimensions and power are given in the Journal 

 for July last, p. 243, Vol. V., under the head of " The Monster Steam-Ship."
