Excellent amongst the most noteworthy exhibits of the class ever shown were the steam-power exhibits of these inventors. The Davey Paxman vertical boiler and engine might well apply to itself the not unconfident utterance of the Roman general who proclaimed of himself: “ I came, I saw, I conquered.” Messrs. Davey, Paxman & Co. have a right to say of this machine that “from its first appearance it has been a success, and its sale has gone on steadily increasing till it now reaches several hundreds a year. No boiler in so short a time has ever become so well known, and so deservedly popular." Our own experience of the apparatus is in its favour. We have a three-horse Davey Paxman with which we print the review, and we have no hesitation in stating that it answers admirably. Need we say of the Davey-Paxman boiler that within the outer cylindrical shell is an inner concentric fire-box, and that within the fire-box are water-tubes opening into its side at the lower end into the crown plate at the top. The reader, who may have had some unpleasant experience from the priming tendency of vertical boilers, need have no foreboding as to this specimen; for priming has been prevented, perhaps for the first time, by the clever arrangement by which each tube is fitted at the top by a deflector patented by the exhibitors. Engine and boiler stand together on a cast-iron water-tank, from which the feed-pump draws. By a communication between the exhaust and the tank the water is kept at about 160 degrees. The greatest absorption of heat is secured by this arrangement, approved by all the best modern authorities on boiler making, which enables the gaseous currents in the fire-box to meet in an opposite direction to the currents of water. The engines are well made, well proportioned, and fitted with all the newest improvements. If steam users should prefer an engine not bolted to the cylinder and brackets of the boiler, then the exhibitors have provided a form of engine, which combines lightness with strength, and compactness with facility for examination, cleaning, and repairs. The lightness of these last-mentioned engines should specially commend them to the foreign trade. We are not surprised that the engines already distributed display durability, and give much satisfaction. |
