“This Machine has a Revolving Cylinder of pure Bristol Brushes and has nothing but the Brush Cylinder to drive, making it run extremely light, requiring less than one-half of one-horse power to drive the largest sized Machines.
“There are now over seven hundred of them running, and as far as we know all are giving perfect satisfaction, and we defy any man to show us where one has been superseded by any other Machine; further, we will say that we have put our Machine in place of several other kinds, and have given satisfaction in all cases where others have failed. We find in other Circulars statements that their Machines will make ten per cent. of flour; we say this is exaggerated; we have made five and one-fourth per cent., and say this is more than any other Duster can do with a fair test. We do not make statements that are exaggerated, but only such as we are willing to guarantee.
“For cleaning Cracked Wheat, Pearl Barley, and all this class of material, there is no better Machine, and we can give the best of testimonials of their work on this kind of material.”
This cut is a sectional view of the Machine showing the entire construction, except the Shoe, which will accompany all of the Machines. The Flour and Bran Spouts can be turned to any direction required, independently, to adjust them to any location in a mill.
