CANADA LUMBERMAN AND WOODWORKER 13 "THE DUNBAR 99 STEAM New and Improved LOGGING ENGINES. This is the marhtne for which we claim all the good Qualities possessed by any other and a great many valuable improvements besides. Best on the Market This lime we wish to call your attention to one of many important points which prove conclusively the superiority of the Dunbar Logging Engines: that of the Hydraulic Apparatus for raising' and lowering the Boiler, an invention of cur Mr. Dunbar, Sr. (for which patents are pending).. By this device all danger from rush of water to either end of the Boiler, caused by irregularities of the road, is avoided. One of the most serious drawbacks in other Engines is the fact that the Boiler is stationary on the frame, consequent- ly a source of great anxiety because cf the danger to both the Crown Sheet and the Tubes. You can readi- ly understand that in going up or down hill either the Crown Sheet or the Tubes are bared, causing them to become so heated that they will leak badly, and after repetition for a time the Boiler will be practically ruined. This improvement, which supersedes our previous method for raising' or lowering the boiler, has been added since cut herewith shown was made. Should you contemplate putting in a Logging Engine we shall be glad to take the matter up with you and give you all particulars. Quotations for Logging Sleds furnished.
