COAL AND WOOD BURNER.

We make coal, wood and straw burning engines as illustrated on this and opposite page from entirely new designs. The straw burning engine of this style is called the 'Direct Flue.'

This center crank engine was designed for a higher speed than the side crank, and you will require a larger cylinder pulley on the agitator to obtain the proper speed.

The crankshaft is held by four large and strong bearings; two are at the crank, one is against the pulley hub and one against the pinion. By this arrangement the crank cannot tremble or jar while running on the road, or in threshing; it also keeps the crank in perfect line and makes easy running without danger from hot bearings and insures less friction than you will find in any other engine.

You are enabled to reach every bearing, lever or valve on the engine either in the field or on the road, from the large, substantial foot-board, which is furnished with two large boxes for tools, fuel, etc.

We make the gearing large in diameter and of such strength as is warranted to withstand the roughest usage. Our double crank is not built up with pieces, neither is it made of cast iron as you will find in some engines, but is a forged wrought iron double crank in one continuous piece and extends equally from the center. The driving pulley for running the separator is placed upon one end of the shaft, while upon the other is fixed the driving pinion held in position by the friction clutch.

Water is taken from the steel tank on the side of boiler, or from main water tank, by the independent upright pump and also the American injector on the center crank engines. The independent steam pump will also pump water from the main tank into the steel tank on side.
