UNITED STATES PATENT @FFTCE S. R. ANDRES, OF TROY, AND S. ANDRES AND MCI). BUCKLIN, OF NEW YORK. I. Y.

APPARATUS FOR DRYING GRAIN, MALT, 85c.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that we, STEPHEN R. ANDRES, of Troy, in the county of Rensselaer and State of New York, and SAMUEL Animus and McDoNoUoH BUCKLIN, both of the city, county, and State of New York, have invented a new and Improved Machine for Drying Malt, lVheat, Corn, and other Substances; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification, in which- Figure 1 is an elevation, Fi 2 is a longitudinal vertical section, and Fig. 3 is a transverse section of our machine.

This invention relates to certain new and useful improvements in machines for drying malt, wheat, corn, and cereals, and also granular and other substances, and consists 1st in the use or employment of a rotating cylindrical vessel having curved buckets projecting inward from the inner surface of its shell, and running parallel with its axis, throughout its whole length, so as to lift the grain from the bottom of the cylinder, up along the ascending side of the same, and pour it (the grain) out from the concave edge of each bucket in a regular stream,

until the same shall have reached a given point in the descending side of the cylinder, thus constantly and regularly exposing the falling grain to the action of a current of hot air passing through the cylinder; 2d in the use or employment of a blast of hot air which is admitted through the hollow journal into the cylinder and passes lengthwise through the same coming in contact with the grain falling from the edges of the buckets, and with the changing surfaces of the grain resting upon them, vaporizes the moisture from the grain and escapes therewith through the hollow journal at the opposite end of the cylinder.

To enable others skilled in the art to make and use our invention we will proceed to describe its construction, and operation.

lVe make our cylinder of sheet iron or other material see A, Figs. 1, 2, and 3, and rivet, screw or otherwise fasten thereto the curved buckets B Figs. 2 and 3. To either end of the cylinder we rivet or otherwise fasten a head having a hollow shaft or our nal C Fig. 2, projecting outward therefrom. These heads have openings D, Figs. 2 and 22,614, dated January 18', 1859'.

3, corresponding to the number of buckets, and placed between them, see E, Fig. 3, outside of each of these cylinder heads, and fitting on their journals, we place a head, one of which F, Fig. 2, has a feeding hopper with the opening Gr, corresponding successively during the revolution of the cylinder with the openings 1), Fig. 2, so as to admit the substance to be dried into the cylinder thereat. The other head H, Fig. 2, we make similar to the head F, Fig. 2, save that it has a delivery spout in place of a hopper, and is placed below so as to allow the dried material to issue therefrom. These heads do not revolve with the cylinder but are kept against it by proper set screws in the frame. The cylinder we hang to the frame I, so as to freely revolve upon its journals, being turned by means of the bevel wheel J, and bevel pinion F. The frame I is hinged at L, the center of which corresponds with the center of the bevel pinion shaft M, Figs. 1 and 2, so as to allow the receiving end of the cylinder to be elevated to any required angle, so as to allow the substance under drying process to move from the receiving to the delivery end of the cylinder. o connect the hollow journals C, Fig. 2, at N, Fig. 2, with a suitable pipe from a blower so as to cause a blast or stream of hot air to enter the cylinder thereat, and passing through the same escape at the opposite journal.

Operation: The substance to be dried is supplied to the hopper, and the cylinder having been adjusted to the proper angle is put in motion, and the blast is also put on, the opening I) in the cylinder head comes opposite to the corresponding openings G in the feeding hopper, the grain passes into the cylinder, and falling among the buckets is carried upward by them on the ascending side of the cylinder, and poured therefrom as the angles thereof change. The current of hot air thus comes in contact with every part of the grain and takes up or vaporizes the moisture therefrom and carries it out of the cylinder, while owing to the angle of the cylinder the grain falling from the buckets lodges every successive time at a point nearer the delivering end until it reaches the same and escapes from the spout, the cylinder and blast being so adjusted to each other that the required state of dryness is attained in the passage of the grain through the cylinder. It is sometimes necessary however to charge the cylinder at once through a hollow journal or its equivalent when said current of hot air is brought into direct contact with the substance to be dried 15 thereby, in combination With a cylinder, made adjustable to any angle as described.
