THRESHER AND SEPARATOR. 
§ 28. The other attachment for the Thresher is for separating the grain and chaff from' the 
straw. See Plate II. The Thresher, when used with this attachment, threshes the 
grain, and simply separates the straw, and delivers it ready for stacking from the end of the 
separator, the grain and fine chaff falling through the openings upon the floor or ground, 
under the same. This grain or chaff is often removed by an attendant to an ordinary Fan- 
ning Mill, and cleaned at the same time, the Fan Mill being driven by hand, or by a band 
from the Horse Power. 
The Separators are simply large wooden riddles, about three feet wide and ten feet long, 
with thin, light wood bottoms, perforated full of holes, about one inch diameter, made strong 
and light. When made for exportation or very changeable climates, with extremes of heat, 
moisture and dryness, perforated and corrugated sheet iron is used for the Separator bottoms, 
in place of the common thin, light wood, which would soon become rickety, and to pieces, 
with little use to the owners. They are suspended about two feet from the floor by means 
af two straps or chains at their corners next the Thresher, and to hooks for the purpose in 
the Thresher, as shown in Plate II ; the other end being upon swing legs which stand 
upon the floor and connected to them by an iron rod running through them, and the end of 
the said Separator. 
The Thresher, for this connection, has a shaft with a crank on it attached crosswise and 
under the feeder's table ; the shaft extending outside and receiving a pulley which engages 
the horse power band precisely as in the case of the fan shaft and pulley, as described in 
section No. 20. From this crank a pitman extends midway under the Thresher, to the 
under side of the Separator, by which it is agitated and does its work better than three or 
four men could do it by hand by any other means. This crank and pulley is changeable to 
either side, to operate right or left handed.

§ 29. The Two-Horse Power, with this Thresher and Vibrating Separator, will, with three 
or four men, thresh from one hundred and seventy-five to two hundred and twenty-five 
bushels of wheat or rye, and with one or two more men nearly double the amount of oats, 
barley and buckwheat may be threshed in ten hours as an average of good grain. With a 
good Fanning Mill, and a connection with the Horse Power by a band to drive it, and one 
man to attend it, the grain may be cleaned up at same time.

§ 31. It is sometimes desirable, on account of the position of the Horse Power and band, to 
have a guide pulley to keep the band steady and in constant contact with the iron pulley on 
the crank shaft of the thresher. This guide pulley is about eight inches diameter and three 
inches face, and runs upon a small, short shaft, which is fixed to a block of wood. This 
block is screwed to the side of the Thresher, and holds the pulley just over and in contact 
with the band. This guide pulley is indispensable with the Thresher and Cleaner, as it 
insures a perfect uniformity of force and motion to the Fan Mill and Shoe. 
§ 32. As the whole of the working parts of the machinery of the One-Horse or narrow 
Power are in every respect duplicates of those in the Two-Horse Power, the same force is 
required to operate them as is required for the Two-Horse Power. Therefore, the effect of 
one horse, when used in either the wide or narrow Power, being precisely the same, it is 
desirable always to use the wide Power, whether for one or two horses, and for any kind of 
work. From long experience the problem is demonstrated, that when one horse- alone is 
is used, he will accomplish, say two hundred bushels threshing of oats per day of ten 
hours, while the addition of one horse in the wide power, without perceptibly increasing the 
friction, increases the amount of work at the ratio of five hundred bushels of same grain 
in same time, with simply the additional attendance of men to handle the grain and straw, 
and keep pace with the increased power of the second horse — an increase of 150 per cent.
