.To all whom, it may concern,.- j

Be it known that I. FRnDarcH MELKERs MAN, a citizen of the United Statcs, residing at St. Charles, county of St. Charles,and State of Missouri, have invented certain new and useful Improvements in Centrifugal Grain- Drying Machines, of which the following is a specification.

My invention is especially7 designed to dry grain, particularly oats.

I have found it desirable in hulling, cleaning, 4and purifying grain to pass itfrom ahulling machine to a washer. After passing through the washer it is desirable to dry the grain, and my improved apparatus is especially designed for this purpose.

Briefly stated, it consists of arotary strainer of au improved construction,adapted to separate the water and moisture from the grain by centrifugal action,to deliver to suitable receptaclcs, and to subject the grain during the operation to currents of air to aid in the drying operation. l

In the accompanying drawings, Figure 1 is a plan view of my improved apparatus, the hopper being removed; and Fig. 2 a vertical section thereof on the line 2 2 of Fig. l.

The top plate, A, of the main frame is arranged on suitable standards, B, and is provided with a central opening,G, through which extends a funnel-shaped hopper, D. A funnel-shaped strainer, E, is arranged around the inner end of the hopper and is secured to a carriage, E4. The carriage E1 consists of a cylyindrical casing, to which the upper end of the strainer is secured. The lower end of the strainer is secured to theloottom of the carriage by the convex plate E', located Linder the hopper D a short distance below its inner end. The carriage is provided on itslowcr side with a boss, F, which is secured to the drivingshaft G. Thedriving-shaft is mounted in bearings in the main frame, as indicated. The strainer is perforated throughout, and is sup ported by triangular braces E2, located loetween the carriage and the plates Eof which the strainer is formed. The plates E3 are of segmental shape, and are secured to the braces at their point of junction, at which point are secured ribs or wings H, which extend from the lower to the upper end of the strainer.

Around the carriage is arranged a jacket, I, at the top of which is an inclined annular deiiector, J. Thejacket extends part way under the carriage, and has a discharge-opening around the drivingshaft. An annular parti tion, K, is arranged around the jacket and loetween it and aninclined outer casing, L,which is secured to the top plate, A, and opens atits lower end over an annular trough, M.. Thel partition K is supported on braces K', secured to the standards. The lower end of the outer casing may also be attached to these braces. The trough M is provided with a dischargeopening, M, and one or more discharge-open ward the spout M' to facilitate the delivery of 7 5 the grain. The water and moisture vthat come in with the grain pass through the perforated plates orstrainersinto thespacebetween the strainer-plates and through the openings L in the carriage, thence into the space between the carriage and the jacket I, and so out through the discharge-opening. Some water may by centrifugal action be carried up along the surface of the inclined strainers and strike against the inclined deliector J. This deflector will stop the progress of the water and deliver it into the space between the carriage andthe jacket I. It will then find its way to the discharge-opening of the jacket. The carriage carrying the strainers is rapidly revolved, and currents of air are induced by the ribs or wings I-I. These currents of air will aid materially in drying the grain. r

This application is a division of an application filed by me July 16, 1887, serially numbered 244,528. Any patentable matter shown in said application and not herein claimed is disclaimed in favor of said application and other divisions thereof.

I claim as of my own invention-m 1. The combination, substantially as hereinbefore set forth, of the main frame, the ro IOO tary carriage, and the strainer mounted inthe carriage, with the hopper extending into the strainer,A4 the convex plate below the mouth of the hopper, and the radial ribs or Wings arranged on the inside of the strainer and extending frorn the convex plate to the other end of the Strainer.

2. The combination, substantially as hereinbefore set forth, of the main frame, the rotary carriage mounted therein, and the funnelshaped strainer mounted in the carriage,with the hopper extending into the inouth of the strainer, thc convex plate on thebottoin of the Strainer under the mouth of the hopper, and the radial ribs or wings extending from the convex plate to the top of the strainer.

3. The combination, substantially as hereinloefore setforth, ofthe main frame, the carriage, the strainer mounted in the carriage,and thejacketsurroundingthe carriageand having a discharge-opening at the bottom,with the annular detlector arranged around the top of the carriage and over the jacket, the outer casing,

the partition between the outer casing and thel jacket, and the annular trough arranged under the outer casing.

4. The combination, substantially as hereinbefore set forth, of the main frame, the rotary carriage having a Water-discharge opening nearthe bottom,the funnel-shapedstrainer contained in the carriage, and the jacket surrounding the carriage to receive the Water therefrom, With theinclined annular deflector arranged around the top of the carriage and over the jacket and provided with an annular water-opening into thejacket around the carriage, the inclined outer casing, the partition between the outer casing and the jacket, and the top plate over the partition and the outer casing.

In testimony Whcreof I have hereunto subscribed my name.

FRIEDRICH MELKERSMAN.
