Specification of Letters Patent.

Patented Dec..25, 19.06. i

To` all wlom, it may concern:

Beit known that I, JAMES E. GooDHUE, a citizen of the United States, residin at St. Charles, in the county of Kane and State of Illinois, have invented a new and useful Improvement in CornHarvesters, of which thev tion in addition to their snapping function;

and lto this end my inventionconsists 1n the construction hereinafter described and claimed to render the snapping-rollers also husking or stripping rollers..

In the accompanying drawinvs, Figurel is a view in side elevation, mainlny dotted, of a corn-harvester containing my improved rollers; Fig. 2, a View in elevation of one of the two similar improved rollers, and Fig. 3 an enlarged cross-sectional view diagram- -matic in its nature taken through the two `coperating1rollers and representing them in the act of corn. A

A denotes in its entirety a corn-harvester, that illustrated being as to all details except the rollers to which my invention relates like that shown and described in my aforesaid Letters Patent, No. 788,205, so that it usking and snapping an ear of is unnecessary herein to describe that machine. However, my present improvement is not intended to be limited for use with that particular construction of corn-harvester.

B and C are the two similar rollers adapted to be journaled, as usual, at their opposite ends in the frame of the machine A. From the lower end of each roller to a point about midway between its ends it is provided with double spiral blades a b of uniform thickness throughout, forming the grooves c. The blade a, terminates at its upper end in a wider spiral section a', having blunt teeth a2 formed about it, and a similar section b terminates the corresponding end of the spiral b and is provided with teeth b2, like the teeth a2. Beyond the section b2 the roller is preferably fluted to its upper end, as represented at d. These rollers are mounted in the machine A and are actuated as set forth in my aforesaid Letters Patent No. 788,205.

In the travel of the machine along a .row of standing corn the cornstalks in succession enter the space between the rollers at their lower or forward ends and are enga ed and steadied by the coperating spira s upon them. As the rollers rise along a stalk until y the toothed sections a b engage the base portion of an ear of corn (represented at D in Fig. 3) the rotation of the rollers causes the teeth of these cooperating sections to bite into the husk at the base of the ear and exert upon it the initial gathering and resultant stripping action, (indicated said re which is succeeded under the contlnued action of thel teeth by snapping the ear., as at fr, and thereafter the continued action of the toothed sections advances the ear through and forces it out of the husk, which thus remains attached to the stalk, while the ear is thrown out. Any waste that may be separated from the stalk and husk by the described operations of the rollers is carried u ward between their iuted sections d and discharged from the machine before they can enter and clog its gearing. f

What I claim as new, and desire to secure by Letters Patent, is-

Y1. In a corn-harvesting machine, the combination-with the frame, of a pair of inclined, rotary and cooperating combined snapping and husking rollers provided alon their lower forward en`d portions with spira blades forming stalk-engaging grooves and terminating at their upper ends in toothed sections, for the purpose set forth.

2. In a corn-harvesting machine, the combination with the frame,I of a pair of inclined, rotary and coperating combined snap ing and husking rollers, provided along t eir lower forward end portions with spiral blades forming stalk-engaging -grooves and terminating at their4 upper ends in toothed sections, with fluted sections on the upper and IOC rear end ortions of the rollers, for the purl forming stalk-engaging grooves, each blade pose set orth. v Y terminating at its upper end in a. toothed 3. In a, corn-harvesting machine, the comsection, for the purpose set fortl. bination with the frcme, of a pair of inclined, JAMES E. GOODHUE-` 5 rotary and co erating combined snapping In presence of i and husking ro ers, each provided along its W. B. DAVIES, lower forward end portion with spiral blades i C. W. WASHBURNE.
