DRIER FOR GRAINS OR SEEDS.

Specification of Letters latent.

Patented Nov. 5, 1912.

Application filed February 1, 1912. Serial No. 674,666.

Shelby, Michigan, have invented certain new and useful Improvements in Driers for Grains or Seeds, of which the following is a specification.

This invention relates to improvements in driers for grains or seeds, such as beans, being especially adapted to the drying of beans.

The objects of this invention are: First,

- ity. Second, to provideimproved means for distributing beans or seeds of various description in a thin layer or stream whereby they will be rapidly and effectively dried. Third, to provide improved means of dis tributing beans or seeds in a thin layer or stream and circulating heated air in contact therewith. Fourth, to provide improved means of forcing a circulation of air into contact with a layer of beans or seeds that is being effectively advancedto thoroughly dry the same, or to heater to cool the same,

as the case may be. I

Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and mechanisms described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure comprising a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a perspective view of a drier embodying the features of my invention. Fig. II is a vertical, detail'central sectional elevation through the same, taken on a line corresponding to line 22 of Fig. III. Fig. III is a horizontal sectional view taken on a line corresponding to line 83 of Fig. II, showing details of construction and means for oscillating the main drum of the drier.

In the drawing,sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to similar parts throughout the several views. j

, Consider ng the numbered parts of the drawing, the main frame is made up of corner posts 1 and connecting cross pieces 2 at the bottom and cross pieces 3 at thetop. A hollow base 4 is provided, containing a burher 5 of any suitable description supplied with fuel by pipe 6. The base is suitably opened to admit the necessary air for maintaining combustionthrough the drier. A cross plate 7, perforated at the center, is above theburner and a baffle plate 8 is disposed above the central opening to distribute the heat laterally and prevent too direct a current. from the flame of the burner. The base has a top 9 with central perforations 10 for delivering the heated air upwardly therefrom.

The outer shell 11 of the drier extends down about the base 4 and substantially contacts with the same; Disposed between the central hollow cylinder or shell 12 and the outer shell 11 is a spiral conveyer 13 of perforated sheet metal 13, extending from top to bottom of this main drum of the drier with a very gradual descent, the succeeding spirals being two or three inches apart. The central shell 12 has a perforated bottom 14, which is journaled on the vertical pin 15 which is carriedon the top 9 of the base 4.

Lateral perforations 16 lead radially in every direction from the central shell 12 into the space between the spirals for delivering a current of heated air laterally directly into contact with a layer of beans or any seeds or grain that maybe advancing upon the spiral iconveyers The top 17 of the central shell 12 is imperforate. A journal pin 18 extends upwardly therefrom. A cross bar 19 secured to the main frame is provided with a journal bearing'20 at its center toreceive the said journal pin 18. It will therefore be seen that the main drum of the drier is pivotally supported-at top and bottom and is free to oscillate on its vertical axis. A feed hopper 21 delivers into the spiral conveyers at the top and a discharge spout 22 leads out from the bottom of the spiral conveyer. The top of the shell is open and a rotary fan 23 for drawing air up through the drier is journaled at 24-on the top bar 19 and is driven by beveled gears 2526 from the shaft 27, which is driven by the pulley 28. Any suitable suction fan can be provided for the purpose and serve very effectively.

The upper endof the shell 11 is embraced by adome 30, having a skirting 31 extending down around the same to increase the efficiency of the fan and to conduct the moist air away from the drier. This, however, is not a necessity but a great advantage.

On the opposite end of the shaft 27 from the pulley 28, is a pulley 32 over which passes a belt 32 to a pulley 33 carried on a shaft'3t supported in suitable boxings on the posts of the mainframe. A disk 35 is carried by shaft 34 and drives the pitman 36, which is connected by a wrist pin 37 thereto. The pitman connects at 38 to a reciprocating bar 39 which is supported in guides 4041 on the posts of the main frame. This reciprocating bar 39' is connected by a link 42, see Fig. III, to the shell 11 to oscillate the same. A hoop 45 is disposed around the shell and the link 42 is connected by pivot 43 to the reciprocating bar 39 and by pivot 44 to the hoop 45. It will thus be seen that when the pulley 28 is driven by suitable power that the fan will be operated to create a suction above the drum, and that through the connections referred to, the drum will be oscillated back and forth by the reciprocating bar 39. Any seeds or grains delivered to the conveyer through the hopper 21 will be immediately spread out, owing to the shaker effect, on the thin heated metal plates of the conveyer and owing to the pressure of the heated air within and the suction of the fan above, a current of hot dry air will be drawn over the thin stream of beans or grain as it is advanced step by step from the oscillation of the drum from top to bottom of the conveyer 13. As the thin stream of beans or seeds is constantly meeting with a current of fresh heated dry air, it 1s very clear that the moisture will be very rapidly absorbed therefrom and the heated and moist air will be passed out at the top and fresh heated dryair will be delivered to the thin stream of beans or seeds at the end of its course so that the same will be completely dried, and, at the same time, the dry air circulating through will pass on to the more moist stream of beans or seeds above until it becomes thoroughly saturated before it is amount of heat and energy expended in securing the finaldrying of the beans or seeds that may be introduced into the drier.

The structure can be greatly. modified without departing from my invention. Any

, source of heat will be effective in delivering heated air through the apparatus through the thin layer of beans or grain. If the air is merely dry it will be somewhat effective,

but, of course, the heat greatly increases .3 the action owingto the fact that the'heated air passing up through the device heats the sheet metal beneath and thus heats the contents and also circulates heated air above the layer in the conveyer and greatly facilitates the drying. Also by this means the heated air is delivered to all parts of the apparatus in a dry condition, and circulates rapidly up and out of the apparatus, doing its work effectively. 7

The drier, as it is illustrated, is very effective. However, the same can be made use of as a cooling device by the circulation of cold air through the apparatus, the same being forced through by any means, or drawn through by suction means.

The device will be quite effective if air" be delivered to the bottom only of the spiral conveyer and circulated up through it, but it will be observed that in my special construction, I deliver dry .air' to the entire 7 1.
