To ALL WHOM 1r' MAY CONCERN- Be it known that I, JGHN R. EVERTSON, of Mount Vernon, Posey county, Indiana, have invented a new and improved Grain and Meal-Drier; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of" this specification, in which- Figure 1 is an end view of my improveddrier, partly in sectionthrough the line a: x, tig. 2.

Figure 2 is a vertical longitudinal section of `the same, taken through the line y y, g. 1.

Similar letters of reference indicate corresponding parts.

lMy invention has-for its object to improve the construction of my improved grain-drier patented November 2T, 1866, and numbered 59,989, so as to makeit more effective in operation, and so that the same oiieet may be produced with a smaller amount of fuel; and it consists in the combination of one 'or more additional furnaces, with the furnace and slide* or pan, in such a way' that the-Hue of each preceding furnace may lead into the upper part of the lsucceeding furnace; informing an offset or shoulder-in the pan or slide at or near the point at which the furnaces intersect, and in forming anropening or openings in the cover of' the oscillating-pan, at the intersection of thepseveral furnaces; the whole being constructed and arranged as hereinafter more fully described.

A is the slide or pan which is suspended from the frame B by the rods C, and is oscillated in the manner described in Patent No. 59,989. D is a furnace, placed under the forward end of the pan A, and the flue d of which reads back directly beneath the bottom of the pan A, and opens into the upper part of the furnace E. The furnace E is placed beneath the middle part of the pan A, and its ilu d leads back directly beneath the rear part" of `the pan A, and opens into the chimney F. If desired,l more than two furnaces may be used, and in the case of very long pans this may be advisable, the ue of each preceding furnace opening into the upper part of the succeeding one, in the manner shown in ig. 2. Bythis arrangement the rear part of the oscillatingpan A, into which the wet grain, meal, or other substance to be dried is introduced, is or can be made the hot` test, so `as to thoroughly heat the said substance as it enters the pan so that it may escape at the other end through the dischargingspout G, thoroughly dried. At or near the point or points'at which the flue ot' the preceding furnace opens into the upper part' of the succeeding one, is formed an otfset, shoulder, or step, a', three inches, more or less, in height, according to the size of the pan. As the grain or other substance to be dried passes down the offset a', it is turned over, so that it may issue from'the spout G thoroughly and evenlyw dried. ,i II is the cover, which ts upon the top of the pan A, and which may be made in one or more pieces or parts, as may be desired or convenient. In the cover H, at or near the o'set or offsets a', are `formed slits or openings h,`extending across or nearly across the said cover H, through which the steam developed from tho moisture in the grain or other substance being dried may escape, enabling the drying to proceed more rapidly, and so that the said steam may not be again condensed by coming in con-tact with the cool grain as it enters the pan through the hopper I.4

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

' 1. The combination of two or more furnaces, D E, with the oscillating-pan A, in such a way that the flue of each preceding furnace may open into the upper part of the succeeding furnace, substantially as herein shown and described and for thepurposc set forth.

2. Forming an o'set, shoulder, or step, a', in the oscillating-pan A, at or near the point or points-at which the flue of' the preceding furnace enters the upper part of the succeeding one, substantially as herein shown and described and for the purpose set forth.

3. Forming one or more openings or slits, 7L', in the cover II, at or near the offset or odsets a,substantial1y as herein shown and described and for Ythe purpose set forth.

The abo-ve specication of my invention signed by me this 8th day of May, 1867.

J. R. EVERTSON.
