HORSE-PO IVERS. Fig. 1 is a perspective with cover removed, and Fig. 2 a sectional view of the \Voodbury-Dingee mounted horse-power. made by Russell & Co., of Massillon, Ohio.
The master-wheel is socketed for bars for six spans of horses, with circular travel to rotate it horizontally. It is a double-crown gear, engaging four co-operating bevel-pinions driving an oblique shaft. On this shaft is fixed the large spnr-gear that engages the pinion of the tum bling-rod, or knuckle joint line-shaft. A pulley on this shaft (not shown in the cut) belts direct to the thrasher, or any other stationary farm machine. Fig. 3 shows the manner of installing the appara tus for operation. The tumbling - rod requires bridging where the horses pass over it on each round of travel. Horse-powers of this type are usually geared to drive the tum bling-rod at the rate of from 75 to 100 revolutions per min. Fig. 4 is the Packer upright horse-power. The position of the line-shaft aloft has obvious advantages, but at some sacrifice of firmness, and this device is often preferred for driving the lighter kinds of stationary farm machines. The line-shaft may be swung around
to any angle, and the animals used do not have their travel obstructed and their rate of travel checked intermittently, as is the ease with " down " powers, when the animals step over the tumbling-rod ; there is also a gain in safety. The master-wheel, and all heavy parts of this type of power, are located on or very near the ground, for stability.
