H. FITTS.
Grain Cleaner.
Paten ted April '12. 1859.
UNITED STATES PATENT OFFICE.
HARRISON FITTS, OF SOMERSET, MICHIGAN, ASSIGNOR TO HIMSELF, AND NELSON TURNEL, OF ADDISON, MICHIGAN.
MACHINE FOR CLEANING GRAIN.
Specification of Letters Patent No. 23,641, dated April 12, 1859.
To all whom it may concern:
Be it known that I, HARRISON FITTs, of Somerset, in the county of Hillsdale and State of Michigan, have invented certain new and useful Improvements in Machines for Cleaning Grain. the construction and operation of which I have described in the following specification and illustrated in the accompanying drawings with sufficient clearness to enable competent and skilful workmen in the arts to which it pertains or is most nearly allied to make and use my invention.
My said invention consists in the combination with a rubbing cylinder and a concave which partially surrounds it, of a flexible rubber which is adjustable in relation to both the concave and cylinder as hereinafter set forth.
In the accompanying drawings Figure 1 is a plan of my improved machine. Fig. 2 is a longitudinal sectional elevation of it.
A is the frame of the machine.
B B are the sides.
C C are the fans by which the blast of air is produced which separates the chaff and light particles from the grain.
D is the frame in which the screens or sieves E are hung. These sieves are made of sheet metal by punching; the punching being so done as to give the interstices an angular direction forward and upward as shown at c c, by which the like direction is given to the blast as it passes upward through the screens, and as the screens so made and arranged gather the air passing outward, more readily than the sieves in ordinary use, a much more efficient and satisfactory upward action of the blast through the grain which lies upon the screensis secured, and the chaff and light particles which may lodge upon them is thereby more effectually removed.
F is an emery wheel which receives motion by means of a belt G which runs over a pulley on the shaft of the fan wheel. The grain is received from the screen H and the slide I upon the concave J and passes down between it and the scouring wheel F where it is subjected to the action of the roughened surfaces of the concave J and wheel F. In the lower part of the concave J there is an adjustable elastic pad or rubber K, by the adjustment of which the discharge of grain from between the concave and rubber may be modified to correspond with the work to be done at the time. This pad or rubber is kept up to its place of adjustment by a wedge 70 extending crosswise of the machine immediately beneath it. By this means the discharge of the grain over the piece K, and consequently the scouring action of the rubber and concave upon it may be modified to almost any desired extent.
The particular improvement which constitutes my said invention and which I claim as having been originally and first invented by me is y The combination of the adjustable piece K with the concave and rubber, substantially as and for the purposes set forth.
HARRISON FITTS.
