. Canadian forest industries 1894-1896. Lumbering; Forests and forestry; Forest products; Wood-pulp industry; Wood-using industries. Cylinder Cover Removed. repacking is not required except at long intervals. There is very little friction, and consequently slight wear on the pistons, from the fact that the steam pressure is inside of the inner piston, instead of against it, making the pistons similar to balanced valves. The bearings for the main shaft and crank pin are in the form of bushings and made from phosphor-bronze. From the manner in which steam is applied to the pistons the wear is slight compared with the ordinary engine. When they need renewing the worn ones are driven out and the new bushings driven to place, which can be done by any good machin- ist at a small cost to the purchaser. The crank. Fig. 3.—Carriage Engine. and pin are made from the best quality of cast steel, and the shaft, which is machinery steel, is shrunk into the crank in a solid manner. The outer piston is also made from best quality of cast steel. Every part of the interior of the engine is fitted with the greatest care. The inner face of the cover and all of the working parts of the engine are ground surfaces, made with tools especially designed for the manufac- ture of this type of engine, thus ensuring that the engine is practically steam tight from the start. Everything about the inside of the engine is made interchangeable, and can be duplicated in case of accident on short notice. Fig. 3 shows the carriage engine for setting up and receding head blocks. In Fig. 4 is shown the steam feed, which is recommended to the consideration of saw mill.
