C ORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 569,242, dated October 13, 1896.

Application filed October 12, 1895. Serial No. 565,443. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES S. SHARP, of Auburn, county of Cayuga, State of New York,have invented an Improvement in Corn- IIarvesters, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In corn-harvesters of that class wherein the corn is gathered, cut, and fed along a laterally-confined passage-way in standing position to a binder at least two feeding devices are neoessary-viz., an upper or stalkfeeding device and a lower or butt-feeding device. In some previous structures these feeding devices have been made as feedingchains, moving continuously to feed along the corn, but in practice the weeds, grass, &c., are wound into orbecome entangled with the feeding chain or chains, and in a very short time said chain becomes so clogged or choked as to cease operating. Obviously this trouble is more serious with the lower or butt-feeding chain or chains than the upper or stalk-feeding chains.

One of the various improvements which my present invention comprehends consists in providing clearing devices for the feedingchains whereby the weeds, grass, 850., will be disengaged from the chains and allowed to pass along freely with the corn withoutchoking the machine. The clearing devices are herein shown in conjunction with the lower or butt-feeding devices only, but obviously can be applied to the upper or stalkfeeding devices, if desirable. The clearing devices may consist of plates located adjacent to the feeding-chains and provided with suitable means for moving them inwardly to push the weeds, grass, &c., away from said chains, thereby allowing them to pass freely along with the corn. I find that good results are produced by reciprocating these plates in such a manner that theyact intermittently on the material which is held or engaged by the feeding-chains. For simplicity a single plate may be provided as a clearing device for each feeding-chain, being made substantially as long as the acting face of the chain. When two feeding chains are employed, which receive the corn between them and feed it along, two such plates may be provided, and they may act alternately, if desired. It is furthermore very desirable, and in many cases necessary, to provide feeding devices for the butts of the corn in advance of the cutter, and instead of extending the feeding-chains or constructing them to do the work my present invention comprehends additional feeding devices which assist in presenting the butts of the corn to the cutter, after which it is fed along by the chain-feeding devices. These additional feeding devices may be made as forward extensions on the clearing-plates orotherwise and provided with teeth to engage the corn. hen made as extensions on the clearing-plates, they will of course reciprocate or otherwise move with said plates.

My invention also comprehends certain means for positively presenting the butts of the corn to and packing them into the binder,

said means herein consisting of feeding de-- vices at the rear of the butt-feeding chains which reciprocate and pack the butts of the corn into the binder. These feeding devices may be made as toothed plates, and for simplicity formed as extensions on the clearingplates which project rearwardly beyond the rear ends of the feeding-chains, and when so formed they will reciprocate or otherwise move with said clearing-plates.

My various improvements are herein shown as applied to a harvester such, for instance, as represented in United States Patent No. 539,830, dated May 28, 1895, yet they are applicable to other corn-harvesters.

Figure 1 shows in plan view a corn-harvester embodying my several improvements; Fig. 2, a vertical section of the machine,taken on the dotted line w at, Fig. 1; Fig. 3, a horizontal section of the machine, taken on the dotted line y 11 Fig. 2.

The gathering-arms, consisting of the upper inclined portions a b and lower horizontal portions a b, are supported by the framework and adapted to form a more or less laterallyconfined passageway extending from the forward end of the machine rearwardly toward or to a binder of any suitable construction. A cutter d crosses this passage-way a suitable distance back of its forward end, which severs the corn that is gathered by the arms and presented to it.

and extending from at or near the forward end of the arms rearwardly to or toward the binder, said feeding-chains acting along the adjacent sides of the gathering-arms and substantially the entire length of the laterallyconfined passage-way. Means are provided for operating these feeding-chains to engage and feed along the corn.

So much of the corn-harvesterherein shown, and which it appears necessary to refer to, is substantially the same as in the Patent No. 539,830, heretofore referred to, to which reference may be had.

As a feeding device for the butts of the corn a pair of feeding-chains are located at opposite sides of the laterally-confined passage-way and extending from the cutter (Z to the binder, being upwardly inclined in parallelism with the upwardly-inclined floor or bottom of said passage-way. These feedingchains engage the butts of the severed corn and convey the corn rearwardly toward the binder. Such butt-feeding chains are old and possess certain advantages in continuously feeding along the corn, and as they are not exceedingly taut they yield more or less between the chain-wheels.

The feeding chains are composed of sprocket-chains with teeth moving around sprocket-wheels, and hence comprise many pieces jointedtogether, and the weeds, grass, &c., which are gathered up by the gatheringarms with the corn are wound into and become entangled with the feeding-chains to such a serious extent as to frequently prevent them from operating, thereby choking the machine. The trouble is obviously greater with the butt-feeding chains than with the upper or stalk feeding chains, and to prevent the weeds, grass, &c., from so clogging the feeding-chains and choking the machine clearing devices are provided for said feedingchains, which are herein shown as plates 6 6, located adjacent to the feeding-chains, as, for instance, they maybe located just above said feeding-chains and in parallelism therewith.

The plates, which serve as clearers for the feeding-chains,are made substantially as long as the acting portions of said chains and are movable inwardly to push the weeds, grass, &c., away from or out of engagement with said chains.

The plates e are each loosely connected to crank-arms e, secured to shafts e which occupy substantially vertical positions, sai'd shafts having at their lower ends or secured thereto beveled gears d, which are engaged by beveled gears d, secured to a horizontal driving-shaft 02 As the shaft cl is rotated the shafts e are caused to rotate, but in opposite directions, turning the crank-arms e and thereby moving the plates in and out in a more or less curved path.

The plates 6 are herein shown as having forward extensions provided with adjacent toothed edges, and the forward ends of the plates, or the extensions thereof, are loosely connected by links e to rods 6 The links 6 and rods 6 thus loosely or pivotally support the forward ends of the plates, permitting them to be worked by the crank-arms in such a manner as to act intermittently upon the material. The motion given to the clearingplates thus supported and operated is substantially a four-motion. So far as said plates are employed to act as clearing devices for the feeding-chains they need be made only as long as the acting portions ofsaid chains, and the toothed extensions 6 are provided for the purpose of more positively feeding and more correctly presenting the butts of the corn to the cutter. The toothed extensions 2 therefore extend forward some distance in advance of the cutter. The crank-arms e are herein arranged to cause the clearing-plates to act alternately upon the material, which arrangement appears to produce good results. The feeding-chains cease to feed the corn along after itreaches the binder, and I have therefore provided butt -packers for the corn, adapted to pack the butts into the binder. These consist of extensions 6 upon or at the rear end of the clearing-plates, having teeth formed upon their adjacent faces or edges, and as said toothed extensions are formed integral with or secured to the clearingeplates they are reciprocated therebyjand act alternately to force or pack the butts into the binder.

For the sake of simplicity, as well as for the production of good results, the feedingplates a and the butt-packers e are formed 1 integral with or secured to the clearing-plates.

It is obvious that various modifications of the clearing devices herein shown may be made which come within the spirit and scope of this invention and which act to push away or disengage or disentangle the weeds, grass, &c., from the feeding-chain, permitting them to be fed along freely through the machine with the corn. It is also obvious that the clearing devices maybe provided for the upper or stalk-feeding chains, if desired, or for any portion thereof.
