Application filed July 5, 1901- Serial No. 67,216- (NomodelJ which are designed to cut down the corn in the field, bind the same into bundles, and deliver the bundles at suitable intervals; and one of its objects is to provide means by which any down corn-that is to say, corn which has fallen down and lies upon the ground, and particularly corn which lies parallel or nearly parallel to the line of draft of the machine maybe lifted from the ground and delivered to the cutter in a vertical position.
Another object of my invention is to provide means by which the corn when out may be carried with the stalks in an approxi- 'mately vertical position upward and delivered thence horizontally to the binder and in such a way that the carrying mechanism may not interfere with or strike the ears of corn upon the stalks.
Another object of my invention is to provide a new and improved framework for such corn-harvesters, and particularly to provide a balanced swinging frame, which carries the knife, the corn-elevating mechanism, and
other portions of the driving mechanism and which may be swung about its pivotal point to regulate the height of the knife, and also a front frame, which is adjustably mounted on the swinging frame.
Another object of my invention is to provide a new and improved weeder which will separate the weeds from the corn in the process of harvesting the same. I
Another object of my invention is to provide a new and improved drop-dump bundle-carrier adapted to receive the corn from the binder and to drop the gathered bundles at suitable intervals.
Another object of my invention is to improve corn-harvesters in sundry details, hereinafter pointed out.
I accomplish these results as hereinafter set forth and as illustrated in the drawings.

151 indicates a lever which is pivoted upon the central or tilting frame 29 and is provided at its lower end with a segmental rack 152, which engages with the cog-pinion 149. The lever is locked in place by a segmental rack 153 and the ordinary hand-lever and dog, operating in the well-knownway.
154 indicates a wire cord or rope which winds around the drum 150 and passes over guiding-sheaves 155 156 and has both its ends secured to a suitable cross-bar on one portion of the front frame 142, whereby when the lever 151 is rocked the shaft 148 will be partially rotated, winding the cord upon the drum 150 and raising or lowering the portion 142 of the front frame 142. A precisely similar cord 154 is wound around the drum 150 passing over guide-sheaves 155 156, and is secured at both ends in the same manner to the portion 142 of the front frame 142.
157 indicates rollers which are mounted in brackets 158, carried by the central or tilting frame 29, and bear upon the forward surfaces of the curved portions 143 of the front frame 142, so as to slidingly hold the same between the said roller 157 and the curved portions 124 124 of the central or tilting frame 29.
As is best shown in Figs. 2 and 13, the two portions 142 142 have their bars 145 most widely separated from one another at their front ends and gradually drawn toward each other at their inner ends, so as to gather and guide the corn between them as the machine passes along. As is best shown in Fig. 2, they are also provided with guide-boards 158 158*, which slope upward and toward each side away from each other, assisting in gathering and guiding the corn. Referring to Fig. 13, where it is best shown, 159 159 indicate short shafts which are journaled in suitable bearings 160 160 on the parts 142 142 of the front frame 142. 161 161 indicate sprocket-wheels which are keyed upon the shafts 159 159. 162 162? indicate bevel-gears .which are keyed upon the other end of the shafts 159 159. 163 163 indicate shafts which gears 162 162.
chains which pass, respectively, around the sprocket- wheels 132 and 161 and 137 and 161 and'which are somewhat closer together at the top than they are at the bottom, the sprocket- wheels 132 and 127 being somewhat inclined, as said above, and somewhat nearer together than the sprocket-wheels 161 and 161. The sprocket chains 166 166 carry teeth or fingers 167, which, with their uses and functions, are hereinafter more fully described. When the shafts 127 and 135 are rotated, as above described, the rotation is communicated, by means of the sprocketwheels 132 137 and sprocket-chains 166 166, to the sprocket-wheels 161 161 and thence through interposed bevel-gears to the shafts 163 163.
Referring particularly to Figs. 17 and 18, where these devices are best shown, 168 indicates a crank which is mounted upon the forward ends of the shafts 163 163. As these parts are precise duplicates of one another upon the two sides of the machine, with the exception that the shaft 163 is a little longer than the shaft 163, for reasons hereinafter described, the description of one will suffice for the description of both, as they operate in precisely the same manner except that toward each other, and hence in a reverse direction. Upon the outereud of the crank 168 is pivoted a lifter 169, which is curved upward at its outer end 169 and is provided with aslot 170. 171 indicates a fixed pin secured to the front frame 142 and engaging the slot 170. As the crank 168 rotates in the direction shown in Figs. 17 and 18, the pin 171 engaging the slot 170, the operative end of the lifter describes a movement which, beginning in the position shown in dotted lines in Fig. 17, is first downward and inward toward the space between the parts 142 and 142 of the front frame 142, thence slightly inward upon the ground-line, (indicated by the lines as :r in Figs. 17 and 18,) thence quickly upward on a curved line, and thence upon a, curved line downward and outward to the point of beginning. The movement of the point of the lifter is shown in dotted lines in Fig. 17.
172 indicates a weeder composed of two arms 172 and 172 which are pivoted by ots 173 to two forward-projecting bars 174 on the central or tilting frame. The bars 174 are spaced a distance apart, as is best shown, for instance, in Fig. 5, to permit the.
passage of the corn between them. As is best shown in Fig. 21, the arms 172 and 172" of the weeder 172 are formed somewhat in the shape of bell-crank levers, with the surfaces of the longer arms, which face each other,coming to an angle 175 between the pivotal points 173 and the ends of the arms.
176 indicates spiral springs which are fastened to the short arms of the weeders 172 and 172 and to the framework and tend normally to bring the angles 175 of the weeder in contact with one another in the position shown in Fig. 5 and in detail in Fig. 21", the longer arms of the said weeder projecting forward and separating from one another, so as to receive the corn between them. The lower surface of the arms 172 172 is provided with a series of downward-projecting cross-plates 177. (Best shown in Fig. 21.) The springs 176 are of sufficient tension to prevent the two arms from being forced apart by ordinary weeds that may come between them in the passage of the machine through the field, but are not strong enough to resist the pressure of the stalks of corn, which as the machine is driven forward cause the two arms of the weeder to separate and permit the passage of the stalks of corn between them to the knife above described.
The operation of the weeders will be described hereinafter in describing the operation of the machine.
Figs. 19 and 20 show details of the teeth 167. These teeth or fingers are mounted, as was said above, upon the sprocket-chains 166 and 166 and are curved in such a way that when they are in operative position-that is, upon the front side of the sprocket-chains 166 166 as the same are risingthe fingers extend forward and then curve inward toward each other and downward in order to assist I corn-binder forms no' part of my present invention and, as said above, may be of any well-known and approved description, I have not shown it in the drawings, as to do so would complicate the drawings and render less clear the parts which I have shown and described and which relate directly to my invention. The lower part 179 of the binder-platform 178 is hinged, so as to be capable of being lifted upward when the bundle-dump of the bundlecarrier is operated in the manner and for the purpose hereinafter described. The binder, as was said above, is operated through the medium of the bevel-gear 45, a bevel-gear 180 meshing therewith, and a shaft 181, upon which said bevel-gear is keyed or otherwise secured. The connection of the same with the binder being of any well-known form and description is not shown here for reasons above stated. 182 indicates a bundle-carrier whicln is also carried by the rear frame 25 to one side of the binder-platform 178, as is best shown in Figs. 7 and 10. The bundle-carrier consists of two segments 163 184, which are in the form of an arc in cross-section and are supported at their forward ends by braces 185 186, which are j ournaled 011 the rear end IIO of a shaft 187, which is journaled in suitable bearings in an upright 188, supported upon the rear frame 25. 207 indicates lugs which are mounted upon the outer surface of the segment 183, near its upper edge, and project therefrom, so as to engage the hinged portion 179 of the binder-platform 178 to lift the same when the segments are operated, as hereinafter described.
Referring particularly to Figs. 7, 10, and 15, 189 indicates a circle which is supported upon the longitudinal bars 26 of the rear frame 25atthefrontendofthebundle-carrier. Said circle conforms to the outer surface of the are upon which the segments 183 184 curve and supports the segments at their forward ends,
so that they may be moved around therein. 190 indicates uprights which are secured to the longitudinal bars 26 and whose upper portions on the surfaces which face each other are curved, as is best shown in Fig. 16, to conform to the arc of the segments 183 184 and are grooved, as is best shown in Fig. 16. 191 indicates flanges upon the outersurfaces of the segments 183 184, which movein the grooves in the curved portions of the surfaces 190, operating to support the rear end of the segments 183 184 and to permit them to move therein. 192 indicates a shaft which is supported in bearings 193 194 on the rear frame. 195 indicates a lever keyed upon said shaft 192. 196 indicates a segmental rack which is also keyed upon the shaft 192 near its in- Her end. 197 (see Fig. 5 and dotted lines in Fig. 15) indicates a cog -'pinion which is keyed upon the forward end of the shaft 187 and meshes with the segmental rack 196. 198 indicates a drum which is keyed or otherwise secured upon the shaft 187 close to the braces 185 186. 199 indicates sheaves which are carried by the circle 189 near its upper end and journaled in suitable bearings 200 thereon. 201 indicates cords, one end of each of which is secured to the segments 183 184. The cords 201, passing over the sheaves 199, pass around the drum 198 and are secured thereto. \Vhen the hand-lever 195 is rocked, rocking the shaft 192, the segmental rack operates to rotate the drum 198 and wind the cords upon it, thus separating the segments from one-anotherat the bottom and driving them into the position shown in Fig. 15, permitting, of course, any bundles of corn which have accumulated therein, as hereinafter described, to drop to the ground. The segments 183 184, it will be understood, are normally in the position shown in Fig. 7.
The master-wheel 24 is provided upon its surface with a number of logs 202, which are formed of angle-iron and are set diagonally upon the periphery of the wheel 24, upon each side thereof, so as to leave a space between them, and, as is best shown in Figs. 3 and 7, are staggered.
203 indicates a scraper which is carried by the rear frame 25 and is provided with a footlever 204, by means of which the scraper may be brought against the periphery of the master-wheel 24 in the peripheral space between the inner ends of the lugs 202.
Referring to Fig. 2, 205 indicates a tongue mounted upon the front portion of the rear frame 25. 206 indicates a brace which is pivotally connected with the forward end of the tongue 205 and with one side of the front frame near its front end.
Referring particularly to Figs. 1, 10, and 21, 208 indicates a caster-wheel which is carried by a yoke 209. The yoke 209 has at its forward end an upright shaft 210, which passes through a sleeve 211, so as to rotate therein. The sleeve 211 is provided upon each side with lugs 212, which are jonrnaled in the rear framework 25. 213 indicates a strong spiral spring, one end of which is secured to the sleeve 211 and the other end to a suitable cross-bar 214 in the rear frame 25. The spring 213 tends to move the sleeve 211 backward, andth us to force. the caster-wheel downward, and is strong enough to balance the weight of the rear portion of the machine when the bundles of corn are delivered thereto and carried thereby, as hereinafter described, and to keep the caster-wheel 208 in constant elastic bearing upon the ground, no matter upon what inequalities of ground the other wheels may drop, affording a constant but appropriately elastic bearing andv support for the rear portion of the machine.
The operation of the machine is as follows: The machine is driven forward along the rows of corn with the two portions of the front frame straddling the rows of corn. The forward portions of the front frame being separated from one another and coming toa point, as above described, and then sloping back inward toward each other will operate, by the assistance of the guide-boards 158 158, to lift into an approximately vertical position any stalks of corn which may have fallen out at right angles or approximately right angles with the line of draft. The lifters 169, being so driven as to operate rapidlythat is, giving several movements between the hills and moving in the direction above describedwill pass under any stalks of corn which are thrown down upon the ground in line or approximately'in line with the draft of the machine, and operating across or at right angles with the line of draft of the machine will lift the stalks of down corn which are lying either forward or backward in a line in the direction or slightly to one side of the line of draft, thus lifting all stalks of corn which have not been lifted by the operation ,of the forward end of the machine, as above described. The stalks of corn being thusraised from the ground as the machine is driven forward, the teeth 167 on the front portion of the sprocketchains 166 166 engage with the stalks of corn andllift them still farther. The curved shape of the teeth, curving forward, then inward and downward, as above described, will engage the stalks of corn, lifting them as the ICC) machine is driven forward to a vertical position, but will allow any one tooth if it strikes an ear of corn to slip off and not break the ear from the stalk or the stalk of corn, the stalk being of course prevented from falling by the immediate engagement of the next tooth. The stalks of corn thus lifted, as the machine is driven forward, to a vertical position pass between the sprocket-chains 166 166 and between the two forward portions of the machine backward to the weeder. As was said above, the two parts of the weeder 172 separate to permit the passage of the stalks of corn between them, but remain closed as against any weeds. The weeds thus by the angular separation of the two parts of the weeder are thrown downward and by the assistance of the downward-projecting plates on the under sides of the weeder are turned backward and under, so that they will not reach the knife. The stalks of corn then coming-to the knife 120, which is rotated rapidly, as above described, are severed, the distance of the point of severance from the ground being regulated by the central or tilting frame in the manner above described. The lower end of the cone 63, being immediately back of and under the plate 121, as the machine is driven forward the butts of the cornstalks, delivered thus to a vertical position,rest upon the cone 63 and are carried back-.
ward by the operation of the spiral flange 64- between the guides 69. The reels or heaters 77, rotating in the direction above described, bear upon the upper ends of the stalks of corn, carrying them backward and tending to keep the stalks of corn approximatelyin a vertical position as they travel upward on the surface of the cone 63 and backward toward the binder. As the lower ends of the stalks of corn thus carried upward and backward pass from the cone they are immediately delivered to the beater 87, which, bearing upon the butts of the stalks, carries them backward, the last of the series of reels or beaters carrying the upper ends backward. The boaters are so arranged that as the corn approaches the rear end of the machine the tops of the stalks are carried backward somewhat more rapidly than the butts or lower ends of the stalks, so that when the last of the reels or heaters 77 operates upon the stalks they are thrown backward into the binder, into which they fall in a horizontal position, the butter operating to assist the delivery of the stalks of corn in a horizontal position in the beater, with the butts forward and the tops of the stalks backward. Upon being bound in bundles by any suitable hinder the bundles roll down the binder-support 178 into the bundlecarrier 182, where they are retained until a sufficient number have accumulated. \Vhen a sufficient number of bundles have been received in the bundle-carrier, the bundle-carrier is operated, as above described, to discharge the contained bundles at a required ism for rotating said crank, substantially speed, and the lugs 207, coming in contact, as above described, with the outer end of the hinged portion 179 of the binder-platform 178, raise the said hinged portion and prevent any bundles bound by the binder in the meantime from coming forward and retain the same until the bundle-carrier is again closed for their reception.
' I have shown the devices for engaging the but-ts of the stalks of corn and carrying them upward and backward as consisting of a cone with a spiral flange. Some other form of carrier might be used, however, to effect the same purpose, and I therefore do not confine myself to the use of such cone with spiral flange, except as specifically claimed.
