conn SHELLER Application filed June 1, 1931; Seria1 No.541,4 3 3.-

The invention relates to a sheller and more especially to acorn sheller.

The primary object of the invention is the provision of a machine of this character wherein the same is constructed to take care of an overflow and also to compensate for the feed of the material to the shelling rolls without liability of choking or the breaking of the cob during the feeding operation. v

Another object of the invention is the provision of a machine of this character wherein the concaves for the shelling rolls are mount ed in a novel manner to exert the proper pressure upon the material when acted upon by the shelling rolls and also to avoid choking or the breaking of the corn cob during shelling operation.

A further object of the invention is the provision of a machine of this character wherein the construction thereof is novel in form to assure a perfect shelling operation and to avoid undue overflow as the capacity of the machine is augmented by a. supplemental overflow roller-to take care of excess feeding material thereto.

A still further object of the invention is the provision of a machine of this character which is simple in construction, thoroughly reliable and efficient in operation, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying draw-.

ings, which disclose the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawings Figure 1 is an elevation of a corn sheller constructed in accordance with the invention.

Figure 2 is a vertical longitudinal sectional View thereof.

Figure 3 is a top plan viewwith portions thereof broken away.

Figure 4 is a sectional view on the line 44l of Figure 2 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views 1n the drawings. 1

"Referring to the drawings in detail, the

machine comprises a box-like body 5 open at its top and bottom and is preferably of rectangular contour having journaled transversely'therein a pair of corn shelling rolls 6 and an overflow corn shelling roll 7, the journals 8 of these rolls being suitably mounted in the longitudinalisides of said body 5 and atone side ofthe latter these journals are extended to carry belt wheels 9, these being made fast to said journals in any suite is alternately trained over said wheels 9 so that the said upperstretch will be disposed at the lowermost side of the intermediate .able manner. and have trained thereover an endless belt 10, the upper stretch 11 of which wheel and at the highest side of the outer Wheel 9 of the series so that inthis manner the pair of rolls 6 will be driven in reverse directions 'to each other while the wheel 9 to the supplemental roll 7 will be driven in the same direction as the intermediate wheel of those connected to the. supplemental roll 7.

Above the rolls 6 and 7 andfixed to the side wheels of the body 5 are feed baflles or deflector plates 12 and 13 respectively,.the latter being forthe supplemental roll 7. while the plate 12 is for the pair of rolls 6. It is of course understood that the rolls 6 and 7 are toothed as at 14: in the usual manner.

Arranged below the outermost roll 6 of the pair and also the remaining roll of said pair and the supplemental roll 7 are wire concaves 15 and 16, the latter being of dual formation while the concave 15' is of the single type. The. concave 15 has one end edge secured at 17 to the end of the body 5 pairs of rolls 6 and while the other end edge is curled at 18 about concave 16 of the dual type is stationarily supported between the other roll 6 of the pair and the supplemental or overflow roll 7 by a stationary cross supporting bar22 while the outer ends of said concave 16 are curled at 23 about slidable supports 24: in vertical slots 25 in the side of the body 5, these curled ends 28 and their supports-24L being acted upon 7 by coiled tensioning springs 26 mounted Within the slots 25 so that the said concave 16 in its dual formation will compensate for crowding beneath the roll 6 of said pair and the supplemental roll 7 to avoid choking of the machine and also toeliminate the breaking of the corn cobs during the shelling operation, yet the required pressure upon the material will be had for the proper shelling of' the cobs by the rolls 6 and 7 in the working of said machine.

One of the journals for the rolls 6 carries a power pulley 27 whereby the machine may be operated.

In the operation of the machine under a normal load or feed the pair of shelling rolls 6 will take care of the same but should an overload or an overflow be had in the feeding of the machine with corn ears then this overflow will be taken care of by the supplemental roll 7 and such overflow shelled in the Working of the machine.

. What is claimed is c In a corn sheller, a body open at its top per and disposed for directing materials toward the fixed points of the concaves, and connections between the rolls for operating the same in unison,

- In testimony whereof I affix my signature.
