GRAIN-DRIER.

1 b aZZwh'om it may concern:

Be it known that I, HUBERT C. ELLIs, a citizen of the United States, and a resident of Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Driers, of which the following is a full, clear, and exact description. 1 p 1 The invention relates to grain driers.

One object of the invention is to provide a grain drier which is adapted for installation in one of a series of circular grain bins of usual construction. In recent years, the circular grain bin has gone into use and the present invention provides a. grain drier which is adapted for installation in one of such bins.

A further object of the invention is to provide an improved grain drier in which the constituents are arranged so as to minimize friction losses caused by bends and angles in'theexhaust and supply passages be: tween the drier andthe fan.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings; Figure 1 is a sideelevationof the improved drier, the grain bin in which the drier is located being shownin section. Fig. 2 is a plan, the bin being shown in section. Fig. 3v isa section taken on line 33 of Fig. 4 and Fig. 4 is a vertical section taken on line 44 of Fig. 1. 4

The improved drier is illustrated as embodied in one of a monolithic series of grain bins, having an annular surrounding concrete wall 5, a base 6 and a bulk-head 7. The compartment a above the bulk-head is adapted to contain a pair of drier sections 8 and the compartment 5 below the bulkhead is adapted to contain a pair of cooler sections 9. These sections may be of any suitable construction, as exemplified by the grain drier set forth in Letters Patent of the United States No. 1,127.96 1 which is of the vertical shaft type. Each drier and cooler section comprises a series of vertical grain shafts 10 and intermediate transverse inlet lines 11 and outletfiues 12 arranged so that the air will be forced from the inlet flues through the grain shafts 13 and into the outlet fines, the inner sides of said fines bein open to the grain shafts. The grain shafts in the drier sections are vertisections.

Specification of Letters Patent. t t 24, 192 Application filed January 2, 1919. Serial No. 269,366.

cally alined with the shafts in-the cooler to cause the grain to flow under usual contrcl from the drier section to the cooler sections. Since the details of these sections form no part of the present invention, further description is not deemed necessary.

A characteristic of the drier which adapts it for installation in a circular grain bin is that, the sections 8 are convergent so that the aggregate area of the outer ends of the sections and the intermediate air chamber 14 will be less adjacent. the circular wall of

ing walls

17 and 18 are formed betweenthe sections toform a convergent chamber 19 between them. Louvers'20 in desired number are formed in the annular wall 5 to regulate the escape of airv which has passed through the drier sections 8 from the chamber a and louvers 21 in suitable number are formed'in the wall 5 below the bulkhead? to regulate the admission of air, into the chamber 5 below the bulk-head from which air is drawn through the cooler sections 9 into the chamber 19.

A fan 22, mounted on the base 6, is disposed in the compartment 1) and is mounted so that its axis will be alined with the center of the chamber 19 between the cooler A suitable inlet trunk 23 leads from the inner side of said chamber to the eye 24 of the fan. This provides a direct passage from the chamber 19. As a result, the air will pass directly from the chamber 19 into the eye 241 of the fan. An outlet trunk-25 is connected to the supply chamber 14 by a duct 26 which extends vertically through the bulk-head 7 and thence horizontally to said chamber 1 1. The fan outlet 30 is inclined to direct the blast into the duct 26 without sharp bends or corners. A suitable heater 27 is disposed in the duct 26 to heat the'air supplied to the drier.

In operation, the fan 22 will draw air from the compartment Z) in the bin below the bulkhead through the grain in the cooler sections 9 into the common chamber 19 between them and through the trunk 23 and into the eyeof the fan; The air thus drawn into the fan will be forced through the duct 26, bein heated in transit therethrough, into the convergent supply cham:

ber 14- between the drier sections 8 from which the air will be forced through the flues and grain in "said sections into the compartment 0; in the bin above the bulkhead.

i As the result of the arrangement of con vergent chambers between the drier and cooler sections, the apparatus is adapted for installation in a grain bin of usual construction. Another characteristic of this construction is that the fan is disposed so that its eye faces or is opposite theisu'ction cham- 'ber 19 and the air is directly discharged into supply duct 26 which is alined opposite the supply chamber '14 and the air is forced through the ducts in such a way as to lessen atmospheric resistance. This arrangement of fan and suction ducts is also of advantage Where it is desired to install a grain drier in any place Where compact arrangement is desirable. The term drier as used herein is to be understood as comprehending a cooler. I

The invention is not to be understoodas restricted to the details set forth, since these may be modified within thescope of the appended claims, without departing from the spirit and. scope of the invention.

Having thus described the inventiomwhat I claim as new and desire to secure by Letters Patent, is:

1. In a grain drier, the combination of a plurality of drier sections having convergent sides, an air chamber between and connected to said sides, and means connected to said chamber for forcing'air therethrough.

2. Ina grain drier, the combination of a 45. In a grain drier, the coinbination with an annular inclosing structure, of a drier comprising sections having sides convergent from the center to the outer. portion of the structure, an air chamber between and connected to saidsections, and means -connected to said chamber for forcing air through the sections. v

5. In agrain' drier, the combination with an annular inclosing structure, of a -drier comprising sections having sides convergent from the center to the outer mmneum structure, transverse inlet and.-' outlet and grain shafts, an air chamber between and connected to said sectlons, and means connected to said chamber for forcing airthrough the sections. r

6. In a grain drier, the combination with an annular inclosing structure of drier "and cooler sections having sidesconvergent from the center to the outer portionof the structure, a bulk-head in the structure between the drier and cooler sections, an airchamber between and connected to said "sections, and meansconnecte'd to said chamber for forcing air through the drier and cooler sections.
