QUADRUPLE EXPANSION YACHT ENGINES. 



THE accompanying drawings, for which we are indebted to 

 Engineering, show a new t'our-cylinrler compound engine 

 lately built by Messrs. Fleming & Ferguson, of Paisley, Scotland, 

 for the steam yacht Skeandhu, also design* d and built by them. 

 The yacht is of steel, 65ft. long, 10ft. 5in. beam, and oft. Sin. draft, 

 33 tons, Thames measurement, and schooner rigged. The engines 

 are of 120 H.P., with cylinders 7, 9, 1214 and 18in. by 12in. stroke, 

 the working pressure being 1201bs. The details are peculiar, the 

 object being to secure compactness, low weight, easy access to 

 each of the four cylinders, and simplicity of working parts. The 

 four cylinders are placed one at each corner of the frame, conse- 

 quently neither is over the crankshaft, which lies in a fore and 

 aft middle line, as usual. To connect the piston rods to the crank- 

 shaft the ordinary connecting rods are replaced by two triangu- 

 lar frames, steel castings, shown in Fig. 2, the lower angle of each 

 holding the crankshaft brasses, while a piston rod is connected by 

 a link to each of the upper angles. A rock arm connected to the 

 center of the upper side of the triangle serves as a guide and also 

 operates the air pump. The two piston rods in each pair move up 

 and down almost together, one being a little in advance, as shown, 

 and t he two cranks are balanced; while the result, it is claimed, is 

 the same as with four cranks at right angles. The operation of 

 the engine is as follows: "Steam is admitted to the high pressure 

 cylinder by means of the piston valve placed between the first 

 two cylinders. The steam passes first into the space between the 

 flanges of the valve, aud not into the steam chest. Thence it is 

 admitted to the cylinder through the center cylinder port, and, 

 having done its work, exhausts into the casing. It must now be 

 explained that the valves to each pair of cylinders are placed one 

 above the ether on one valve rod, and work in one steam chest 

 common to both. It will be seen, therefore, why it is necessary 

 for the boiler steam to be admitted inside the valve, or, in other 

 words, hetween the flanges, as otherwise the high pressure steam 

 would pass into the second cylinder as well as the first, the valve 

 chest space being common to both valves and cylinders. The 

 steam, escaping from the first cylinder, fills the valve chest, and 

 is admitted to the second cylinder in the usual way, the exhaust 

 this time being carried by the inside of the valve. Steam is then 

 taken to the next two cylinders, and the same action is gone 

 through once more, until the steam escapes to the condenser in 

 the usual way. 



'"The valves are worked by eccentrics and reversed by the link 

 motion, but the arrangement is necessarily peculiar. The valves 

 for the third and fourth cylinders are placed directly over the 

 cylinders, and can be worked by eccentrics in the usual way. 

 The valves for the first and second cylinders, however, are con- 

 siderably on one side of the fore and aft center line. In order to 

 work the valve rod common to these, an arm or connecting rod 

 is taken from each of the eccentric straps, and these arms work 

 the link motion by means of a bell crank lever attached to the 

 engine bed. in Fig. 2 the arm of one eccentric can be plainly 

 seen, together with the bell crank lever and the connecting rod 

 carrying the motion to the solid bar link. The reversing links 

 are placed one immediately in front of the other, and are pulled 

 over by one lever and drag links. It will therefore be seen that 

 only two eccentrics are used for all four cylinders, and only one 

 would be required in a non-reversing engine." From its low 



weight aud compact form the engine is specially adapted for war 

 ships. The huiiders are now at work on an engine of 1800 H.P. 



BABOON AND XARA. 



A PRIVATE match was sailed between these two cracks on 

 July 9, over a course 10 miles to leeward and return, off Mar- 

 blehead. Baboon is 52ft. over all, 39ft. 6in. l.w.l., 13ft, beam and 

 8ft. draft, measuring 40.80 by E. Y. C. rules; while Xara is 48ft. 

 over all (plumb stem), 39ft, Sin. l.w.l., 13ft, beam and 8ft. draft. 

 Baboon was sailed by Messrs. C. F. and G. C. Adams, Mr. Agassiz, 

 of the Zigeuucr, and a crew of three; while Mr. Meers and Mr. 

 Fowle, with Capt. Haff, Sr., and his son, besides a crew of three, 

 sailed Xara. The wind was steady from S. W-. during the race, 

 with smooth water. The first whistle was blown at 1:38, with start 

 ■at 1:43, Baboon crossing at 1:44:15 aud Xara at 1:44:55. Both carried 

 clubtopsail and spinaker, while Xara also set her balloon jibtop- 

 sail. Xara at first outran her rival, and at the end of half an hour 

 was some 50vds. ahead, but then Baboon overhauled her and the 

 two ran side by side for a time, Baboon finally going ahead. Both 

 came to the turn together, Xara getting in her ballooner in good 

 season and cleverly cutting the other boat out at the mark, cross- 

 ing her bow and turning at 3:09:30 with 20 seconds lead. 



Once on the wind Baboou speedily left the other, outpointing 

 her, until Baboon's topmast stay parted suddenly. Xara soon 

 passed her and took the lead, both going on starboard tack about 

 the same time. Baboon fought for some time to regain the lead, 

 and was finally successful. At 5:15 Xara, then astern, drew off 

 her bobstay plate, being obliged to take in her jib and finish under 

 main and staysail. The times were:

COOPERS POINT CORINTHIAN Y. C — Editor Forest and 

 Stream: The seventh and combination (open to all) race of the 

 season took place on June 26. Fiteh wins in first class, closely- 

 followed by Wilkins, second class. Wind heavy from N.W. The 

 16 miles was covered by the Fitch in lh. 56m. 30s. Eighth race, 

 July 10. wind light N.E. Fitch wins again in her class. Almond in 

 second class, winning club pennant for first boat over the course. 

 Cook in third class. Eleven boats entered for the contest. The 

 Coopers Point Corinthians were the first to accept the Quaker 

 City Y. C. invitation to participate in their grand combination 

 race on Sept. 27, open to all clubs and private boats. The Corin- 

 thins will sail t heir ninth race on July 24.— B, G. Wilkins. 



QUAKER CITY Y. C— EdUor Forest and Stream: The cruise of 

 the fleet to Trenton was a good up stream move, and pays a debt 

 long since due to the contingent. Com. Middleton entertained 

 the natives on board the flagship with true sailor-like hospitality. 

 The combination race for Sept. 27, open to all clubs, is another 

 progressive measure of the rejuvenated Q. Y. C. with its fine 

 shore club house and city rooms. But I am sorry to say the club 

 is assuming a social aspect detrimental to yachting. Probably 

 three-fourths of the members are uninterested in the sport and 

 would never learn to be sailors. The editorial in the Forest and 

 Steeam recently on this subject should be posted up in every 

 yacht club room and carefully studied— R. G. Wilkins. 



SEAWANHAKA C. Y. C. CRUISE. 



THE fleet anchored over night on July 4 at Black Rock harbor 1 

 sailing next day for Morris Cove, and on July 6 for Now Lou- 

 don. Next day Newport was reached, and on Sunday the fleet lay 

 at New Bedford. Vineyard Haven was reached on Monday, the 

 fleet starting again oil Wednesday for Bar Harbor. Only four 

 yachts continued the cruise from this point, thy flagship Sea Fox, 

 Com. Canfleld; Medusa, cutter, Vice-Corn. Center; Miranda, 

 schooner. Mr. G. H. B. Hill, and Gracie, sloop, Mr. .1. P. E&rle. 



Sailingfrom Vineyard Haven at 7:30, the fleet was off Pollock's 

 Rip at 1 P. M., with a falling barometer and ugly sky. At 3 P. M. 

 the barometer stood at 29.90 on board the flagship, but at 1 A. M. 

 dext day it was 39.30. At 2 A. M. a heavy gale set in, Sea Fox aud 

 Gracie running for five hours under bare poles. Miranda hove to 

 for the same time under throe-reefed foresail. The little cutter 

 Medusa set her storm trysail with two reefs and a spitfire jib, and 

 kept on her way. The gale was at its height from 2 until 7 A. M., 

 when the wind fell, but the sea continued very heavy. The fleet 

 kept on under double-reefed canvas, reaching Bar Harbor the same 

 afternoon. While at Bar Harbor the secretary's prizes for sea- 

 mauship and perfection of equipment were awarded, the first 

 prize, $25, going to Capt. Petersen, cutter Medusa, and the second, 

 $10, to Capt. Fish, schooner Miranda. On July 15 the fleet sailed 

 for Portsmouth, N, H., from which port it will return to Newport 

 and disband.
