CORN SNAPPING AND HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 79 1,50 1, dated July 11, 1905.

Application filed April 22,1905. Serial No. 256,950.

To all whom it may concern..-

Be it known that I, ENOOK M. J ETSON, a citizen of the United States, residing at Mabel, in the county of Fillmore and State of Minnesota, have invented a new and useful Corn Snapping and Husking Machine, of-which the following is a specification.

This invention relates to corn snapping and husking machines; and it has for its object to simplify and improve the construction and operation of this class of devices, and more especially to assist in transferring the ears snapped from the stalks that pass between the snapping-rolls to the husking-rolls.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims. 7

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention.

In the drawings, Figure 1 is a sectional side elevation illustrating a portion of a cornharvesting machine embodying the invention. Fig. 2 is a detail front view, partly in section. Fig. 3 is a front end view of the snapping-rolls.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The frame 1 of the machine is supported in part upon the bull-wheel .2, from which motion is transmitted to live parts of the machine, as will be presently described. The snapping-rolls 3 3 are mounted upon shafts 4:, which are supported for rotation in boxes 5, said boxes being slidably supported in slots 6 in the frame of the machine, said slots serving also to accommodate springs 7, whereby said snapping-rolls are forced in the direction of each other, so as to yield to stalks of different sizes passing therebetween and to enable the snapping-rolls to so engage the stalks that the latter shall be fed or buckled down between the snapping-rolls. The shafts of the latter are provided at their upper ends with intermeshing pinions 8, and one of the shafts is additionally provided with a bevelgear 9, meshing with a bevel-pinion 10 upon asuitably-supported transverse shaft 11, having a sprocket-wheel 12 and driven by means of a chain 13 from a sprocket-wheel 14, which is connected for rotation with the bull-Wheel 2. The snapping-rolls are mainly cylindrical in shape; but they are provided at theirlower ends with longitudinal stalk-engaging recesses 15 of approximate semicircular crosssection, as clearly indicated in Fig. 3 of the drawings, said recesses serving to engage the stalks with a greater degree of certainty than the plain ungrooved ends of the rolls would be liable to do. The stalks are guided between the rolls by gathering devices, including gathering-boards, one of which is shown at 16 in Fig. 1. Gathering-chains, as 17 and 18, are also provided together with suitable means for driving said chains, it being understood that two pairs of chains are to be employed; but this kindof gatheringdevices are common in this class of machines and are not to be understood as forming a part of the present invention.

A bearing-bracket 19, supported in the frame of the machine, servesto support a shaft 20, the axis of which is approximately at right angles to the axes of the snappingrolls. The shaft 20 is driven, as by a band or chain 21, from a shaft 22, having a bevelpinion 23, meshing with a bevelgear 24, which is connected for rotation with the bullwheeL' The shaft 20 supports a cylindrical member 25, which is disposed adjacent to the inner snapping-roll and which is armed with a plurality of series of radially-extending teeth or fingers 26, which are spirally disposed upon the said cylinder, the upper side of which is driven in an outward direction, as indicated by an arrow in Fig. 2 of the drawings.

' Supported for rotation in suitable bearings are a pair of husking-rolls 27, which are inclined downwardly and rearwardly, said husking-rolls being disposed adjacent to the snapping-rolls and to the cylindrical member 25, side guards or shields 28 and 29 being provided to guide the ears onto said huskingrolls and to prevent them from escaping until after being deprived of their husks they slide into a receiver 30, supported in rear of the husking-rolls and which constitutes part of the casing of an elevator or conveyer 31, whereby the husked ears may be conveyed to a suit able receptacle, which may be in the nature of the box of a wagon driven alongside of the machine.

When the machine is in operation, the cornstalks will be guided between the snappingrolls and will presently come into engagement with the spirally-disposed series of teeth 26 of the cylinder 25, which will not only assist in detaching the ears, but which will carry the ears laterally over the inner snapping-roll and deposit the said ears upon the husking-rolls, where the husks will be stripped from the ears and deposited upon the ground between said husking-rolls, while the ears denuded of the husks will pass to the conveyer 31. The teeth 26 are placed closely together, so as to prevent the possibility of any ear of corn passing therebetween, while the stalks engaging between said teeth will be twisted in such a manner as to cause the ears to be easily and infallibly detached, the stalks being finally disposed of by the rolls 3.

As will be plainly seen by reference to Fig. 2 of the drawings, the fingers 26 of the cylindrical member 25 are made of such a length as to overlap the space between the snappingrolls 3, so as to pass naturally and without fail into engagement with the cornstalks shortly after the latter enter between the snapping-rolls, and said fingers are also preferably provided with terminal hooks or bent portions 33 in order to more readily engage the stalks.

The husking-cylinders have been shown conventionally of plain cylindrical form; but it is obvious that said cylinders may be provided with husk engaging and stripping means of any suitable description. It is also obvious that the snapping-rolls may within the scope of the invention be provided with any desired number of grooves or recesses 15,. from one upward.

This invention, as will be seen from the foregoing description, is simple in construction and practical in operation, and it may be readily and successfully applied to various corn-harvesting machines in use at the present time.

Having thus described the invention, what is claimed is 1. In a machine of the class described, a pair of snapping-rolls, a cylindrical member supported for rotation adjacent to and at an angle to said snapping-rolls and having radiallyextending fingers disposed in spiral series thereon.

2. In a machine of the class described, a pair of snapping-rolls, a cylindrical member sup-' ported for rotation adjacent toand approximately at right angles to the inner snappingroll, and fingers extending radially, in spiral series, from said cylinder and overlapping the space between the snapping-rolls.

3. In a machine of the class described, a pair of snapping-rolls, a pair of husking-rolls supported adjacent to the snapping-rolls, a cylindrical member supported for rotation adjacent to the inner snapping-roll and having a plurality of series of fingers, spirally arranged and overlapping the space between the snapping-rolls, and guard-flanges adjacent to the husking-rolls.

4:. In a machine of the class described having a pair of snapping-rolls, a member supported for rotation adjacent to one of the snapping-rolls and having a plurality of spirallydisposed series of radially-extending stalk and ear engaging fingers. V

5. In a machine of the class described having a pair of snapping-rolls and a pair of husking-rolls, an ear detaching and conveying member supported for rotation adjacent to and approximately at right angles to the snapping-rolls, and provided with a plurality of series of stalk and ear engaging fingers.

In testimony that I claim the foregoing as my ownl have hereto affixed my signature in the presence of two witnesses.
