Improvement in Grain-Scourers. NQ 126 56] Patented May 7,1872.

UNITED STATES PATENT OFFICE.
GEORGE S. NEWMAN, OF LIBERTY MILLS, VIRGINIA.
IMPROVEMENT IN GRAIN-SCOURERS.
Specification forming part of Letters Patent No. 126,567, dated May 7, 1872.
Specification describing certain Improvements in Grain-Scourers, invented by GEORGE S. NEWMAN, of Liberty Mills, in the county of Orange and State of Virginia.
This invention will be first hereinafter fully described and then clearly pointed out in the claim.
Figure 2 is a horizontal section, and Figs. 3 and are detail views of a modification hereinafter mentioned; Fig. 1, a vertical section of my improved machine.
A is a rotary and vertical shaft, and C are cup-shaped scourers made of wood, ivory, or emery; and G is a reticulated and funnelshaped scourer. K is an ordinary hopper, through which the grain passes into the first cup. E are fan-wings, attached to these cups on top and raised upon pillars above their surface, while F are fan-wings attached to the bottom. B is an annular wire-gauze cylinder surrounding these cups, and M the casing. Between these two cylinders is formed the dust-chamber L, which is provided with outlet N. Through these cylinders also pass the tubes H to admit the ingress of air or grain. Attached to these tubes are conveyers D, ribbed at d and open around the shaft. 0 is the bottom, in which are discharge-outlets 0 in the annular channel 0.
The mode of operation is as follows: The
grain, being poured into hopper K, is discharged around the shaft A and upon the topmost cup-scourer. The centrifugal power now forces the grain outward, against, and up the concave sides of the cup, and thereby rubs the pellicle of the wheat with a great friction. This detaches all or a portion of the dirt. As it moves up the sides and the dust is being removed the wing-fans E drive the rising dust over the top of the cups through the gauzecylinders B and into the chamber L. When the grain reaches the top of the first cup and falls over its edges it strikes the gauze-cylinder, drops upon a fixed, ribbed, and smooth surface of conveyer D, and is again discharged around the center of shaft A, while the fans F are blowing 011' any loose dirt from it. Here it again falls into a revolving cup-scourer and goes through the same operation, which may be repeated a number of times, greater or less, according to the condition of the grain. The grain is finally received on the bottom 0 in annular channel 0 and discharged through spout 0.
In Fig. 3 P is a valve or stop, attached by hinge to conveyer D, arranged with its lower or outer surface to conform to the concave surface of cup-scourer C, presenting this edge either radially, as at P or tangentially to a small part of its radius, as at JP of Fig. 4. This attachment is intended to be adjusted by a spring to a proper position. It may be made of a simple plate and act only as a stop, brush, rubbing, or grinding surface opposed to the scouring-surface. The upper fans E are dispensed with where this valve, stop, or rubber is used. The spouts H may be provided with hoppers or detachable funnels, by which the grain may be passed with more facility and convenience into the scourer.
Having thus described all that is necessary to a full understanding of my invention, what I esteem to be new, and desire to protect by Letters Patent, is
1. The conveyers D provided with inclined tubes H, passing through the dust-chamber and outer shell, in combination with scourers C, as and for the purpose described.
2. The reticulated scourer O and scourers O, the conveyer D, inclined tubes H, the wiregauze cylinders B, and the casing M, all ar ranged and combined as and for the purpose described.
GEORGE S. NEWMAN.
