CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 727,080, dated May 5, 1903. Application filed June 9, 1902. Serial No. 110,766. (No model.)

To aZZ whom, it may concern:

Be it known that I, EDWARD W. BURGESS, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of'Wisconsin, have invented certain new and useful Improvements in Corn-Harvesters, of which the following is a specification, refer.- cnce being had to the accompanying drawings, forming a part thereof.

Like numerals on the drawings represent like parts.

My invention relates to corn harvesters designed to cut one row at a time, wherein the corn is gathered, cut, and fed rearward in up- 1 5 right. position to an automatic binderthat has its operative shafts inclined forward from a vertical line for a purpose which will be described later. I

The object of my invention is to improve the construction of the machine, particularly to the end that the rearward movement of the corn and its delivery to the binder may be facilitated and made more positive. To attain this object,I provide a guiding passage-way for the unsevered stalks that extends forward of the cutting mechanism and in which the stalks are confined laterally and supported vertically. The stalk passage-way extends rearward from the cutting mechanism and has a closed bottom in rear thereof that inclines upward and rearward to an automatic binder that is inclined forward of a vertical line. The stalk passage-way inclines upward and rearward on its upper face, and corn gathering and forwarding devices operate along its inner faces to gather and forward the corn in an upstanding position to the binder mechanism.

In machines of this type it has been the practice to limit the rearward movement of the forwarding devices in their passage to the binder mechanism to a point forward of such mechanism for the purpose of providing a receiving-chamber in which the stalks are allowed to accumulate during the time in which the stalk-passage is closed by the operation of the binder arm or needle. In other cases the forwarding devices have been constructed to yield laterally under pressure at this time, and others have allowed the carrying-fin'ge'rs to yield under pressure and turn on their pivots backward relative to their operative direction. I have found this receiving-cham her or storage-receptacle unnecessary in the successful operation of machines of this type. In fact at times it becomes an eviland operates to prevent a satisfactory working of the machine; .so, also, with the devices that yield under undue pressure. I have found it more satisfactory to provide a practically unyielding forwarding device that will carry the stalks positively rearward beyond the forward limits of the path of the packers and needle. I also consider it advisable to place the binder as near the cutting mechanism as possible and incline it forward at its upper end that it may receive the stalks as soon as possible after they have been severed by the cutting mechanism and are still in an erect position. I also find it advisable to have the packers and needle operating in planes that are inclined upward and rearward for the purpose of assisting in lifting the stalks upward and reducing the friction of the'butts on the inclined bottom of the passage in rear of cutting mechanism. In the drawings, Figure l is a side elevation of a part of a corn-harvester sufficient to illustrate my invention. Fig. 2 is a top plan view of'Fig. 1. Fig. 3 is asectional end view of Fig. 1 on line A B. Fig. 4: is a detached plan view of the butts-forwarding chains and cutting mechanism.

A suitable main frame 1 is carried by the main wheel 2 and grain-wheel 3. Gatheringsills 4 and 4' are secured to the main frame 1 and extend forward of the same and are braced by the auxiliary sills 5 and 5 also secured to the main frame 1. A gear-frame 6 is mounted on the main framel. A main 9o cross-shaft 7 is gjournaled in the gear-frame 6, and motion is imparted to it through the medium of the spur-pinion S, deriving motion in a suitable manner from the main wheel 2.

A cutting mechanism" 9 is located between 5 the gathering-sills 4 and 4, toward the rear of the stalk passage-way 10, formed by said sills. An automatic binder attachment, consisting in part of a main frame 11,is supported by the main frame 1 in rear of the stalk pas- I00 bleward of a direct line rearward of the cutting mechanism for the purpose of delivering the bound bundles as far stubbleward as possible, that they may be out of the path of the machine and draft-animals on the succeeding round.

The binder-frame 11 is of the usual U form, having the upright tubular arms 12 and 13. The knotter driving-shaft 14 is journaled in the arm 12, located on the grainward side of the stalk passage-way, and the needle-shaft 15 is journaled in the arm 13 on the stubbleward side of said stalk passage-Way. 16 is the packer driving-shaft, to which is secured the triple crank 17, that gives motion in the usual manner to the packer-fingers 18, 18', and 18 19 is the needle. The gear-frame 6 has an upstanding inclined tubular arm 20, in which is journaled a shaft 21, having at its upper end the sprocket-wheel 22 and at its lower end the bevel-pinion 23, engaging with the bevel-wheel 24, secured to the main cross-shaft 7. Secured to the packer-shaft is the sprocket-wheel 25, and a sprocket-chain 26 transmits motion from the shaft 21 to the packer-shaft 16, and this communicates motion to the various operative parts of the binder mechanism in a well-known manner.

The gear-frame 6 is provided with upstand ing tubular arms 27 and 27, located upon opposite sides of the stalk passage- Way 10. These arms are parallel with a vertical longitudinal plane, but are inclined forward of a transverse vertical plane at their upper ends. They form bearings for short shafts 28 and 28, that have sprocket- wheels 29 and 29 secured on their upper ends, and bevel-pinions 30 and 30 secured on their lower ends and engaging with bevel-pinions 31 and 31', secured to cross-shaft 7. Upon opposite sides of the stalk passage-way 10 and near the level of and approximately in line with the cutting mechanism 9 are located idler-sprockets 32 and 32', having their supporting stud-axles inclined forward and upward substantially parallel with the tubular arms 27 and 27. Sprocket-chains, having carrying-fingers at intervals in their lengths, connect the two pairs of sprocket- wheels 29 and 32 and 29' and 32 and are called the butts-forwarding chains. (Shown in Figs. 1 and 4.) 33 in Figs. 3 and 4 represents the preferred form of the carrying-fingers, they being made integral with the links. Secured to the main frame 1 on opposite sides are vertical pipes 34 and 34 and 35 and 35. 36 and 36' are inclined rails upon opposite sides of the stalk passage-way, parallel with the buttsforwarding chains and having a portion at their upper ends curved inward into the passage-way forthe purpose of stripping the stalks from the carrying-fingers. These upper ends are then bent outward and secured to the vertical pipes 34 and 34.

The sprocket- wheels 29 and 29 have the upper ends of their hubs provided with one or more ribs or teeth adapted to engage with clutch members 37 and 37, secured to the lower ends of the inclined shafts 3S and 38. Near the upper ends of the vertical pipes 34, 34, 35, and 35 are secured brackets 39, 39', 39 and 39 To these brackets are secured pipes 40 and 40 upon opposite sides of the passage-way and at substantially right angles to the inclined shafts 38 and 38. To the forward ends of the pipes 40 and 40' are secured upstanding tubular arms '41 and 41'. At substantially right angles thereto short shafts are journaled in the arms 41 and 41, and to the upper and lower ends of these shafts are secured sprocket-wheels 42, 42', and 43 and 43, respectively. To the rear ends of pipes 40 and 40 are secured the upstanding tubular arms44 and 44',parallel with the arms 41 and 41. In these arms are journaled short shafts that have sprocket-wheels 45 and 45 and 46 and 46, secured on their upper and lower ends, respectively. Near the upper ends of the inclined shafts 38 and 38 are secured sprocket-wheels 47 and 47'. The ends of said shafts are journaled in bearing-blocks 48 and 48', secured to the pipes 40 and 40, respectively. Near the forward ends of the gathering-sills and on opposite sides of the stalk passage-way are journaled idlersprockets 49 and 49'. These sprockets are adjustable on brackets secured to angle-steel rails that extend from near the points of the gathering-sills rearward and upward to substantially the level of the binder-needle. The rails are inclined inward and upward for a short distance and then rearward and upward, forming a passage-way from the rear forward with parallel sides for a portion of its length and then flaring outward toward the forward ends of the gathering-sills, as shown in Fig. 2. At points on said rails where they begin to angle outward are pivoted idler-wheels 50 and 50, with flanges on their lower sides, and near their upper ends are journaled similar idlers 51 and 51'. Mounted upon idler sprocket- wheels 49 and 49 and'sprocket-wheels 46 and 46 at the lower ends of counter-shafts in tubular arms 44 and 44 and supported by idlers 50 and 50 and 51 and 51 are sprocket-chains having carrying-fingers, like that shown in Fig. 4, at intervals in their lengths. Mounted upon sprocket-Wheels 42 and 42' and 45 and 45' are other sprocket-chains with carrying-fingers. Near the sprocket-wheels 45 and 45 are located idler-Wheels 52 and 52, similar to idlerwheels 51 and 51. These idlers are adjustably supported on brackets 53 and 53, secured to the pipes 40 and 40 and designed to guide the inner sides of the chains at their delivery ends and by adjusting them inward or outward to diminish or increase the width of the stalk passage-way. The said inner sides of these chains are held against lateral movement between the sprockets by guiderails 54 and 54, that are adjustable with the idlers 52 and 52. Motion is imparted to these several chains by driving-sprockets 47 and 47 at the upper ends of the inclined drivingshafts 38 and 38' by means of the sprocketchain connection between said sprocketwheels and sprocket-wheels 43 and 43, as shown in Fig. l.

The uppermost carrying-chains are called the tops-forwarding chains, the lower car rying-chains are called the butts-forwarding chains, and the middle or long carryingchains are called the gathering and forwarding chains.

The receiving ends of the tops-forwarding chains are substantially in line with the ver-- tical plane of the cutting mechanism, and their delivery ends extend to and beyond the forward limits of the packers and needle of the bindingmechanisin. The receiving ends of the butts-forwarding chains are in advance of the cutting mechanism and their delivery ends are in rear of the forward path of the packers and needle, as shown in Fig. l. The receiving ends of the gathering and forwarding chains are carried as near the points of the gathering-sills as practical, and their delivery ends coincide with the delivery ends of the tops-forwarding chains. The outer members of these gathering and forwarding chains are supported by rails 55 and55, as shown in Fig. 3, .and their inner members are held against lateral deflection by the bars 56 and 56, secured to the angle-steel rails, also shown in Fig. 3.

Houn ted upon the in wardly-cu rved ends of the vertical pipes 34, 34, 35, and 35 are suitable bracket-s that support the inwardly and downwardly flaring boards 57 and 57, that are located above the tops-forwarding chains. From the outer ends of the gathering-sills and extending upward and rearward are other boards flaring inward and downward that are joined to the upper board 57 and 57,

as shown in side elevation in Fig. 1. In rear of the cutting mechanism is hinged a buttsupporting chute 58, that supports the butts of the stalks after they are severed by the cutting mechanism and while they are being forwarded to the binder mechanism.

The operation is as follows: The stalks are guided by the laterally-closed passage-way to the cutting mechanism, extending across it, and any that are leaning or fallen are picked up by the carrying-fingers on the forwardingchains and held upright and carried rearward. The butts-forwarding chains engage with the stalks as soon as they are severedand carry them rearward and upward to the binder mechanism, while the tops are supported and carried rearward by the tops-for- 1.
