CORN-HARVESTER.

SPECIFICATION forming art of Letters Patent No. 429,311, dated June 3, 1890.

Application filed June 24, 1889.- Serial No. 315,399: (No model.)

To all whom it may concern: I

Be it known that I, HARRY L. JONES, a citizen of the UnitedStates, residing at Geneva, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Corn-Harvesters, of which the following is a full, clear and exact description, that will enable others to make and use the same, reference being had to the accompanying drawings, formingv a part of this specification.

This invention relates to improvements in that class of corn-harvesters wherein the cutting, carrying, and binding mechanism are mounted on suitable carriage or truck wheels and drawn by horses, the same consisting of certain novel features in the combination, arrangement, and operation of the several parts, as will be hereinafter set forth.

Figure 1 is a front elevation of a machine embodying my improved features; Fig. 2, a plan with some of the parts omitted. Fig. 3 is a side elevation and part section in plane 3, Fig. 1. Fig. 4 is a plan detail of one of the sickle-bars. Fig. 5 is an enlarged vtransverse sectional detail of the sickle-bars and parts. Fig.6 is a broken-away rear elevation and part section, the rear framing-boards in which the apron-rollers are journaled being removed; and Fig. 7, a broken-away rear elevation with the framing-boards in place.

Referring'to the drawings, 8 represents the different parts of the carriage-frame; 9 and 10, the carriage-wheels5 11, the draft-pole, and 12 the drivers seat.

The required motion is transmitted to the different working parts from 'the ground or driving wheel 9, which is mounted on the axle-shaft 13 (see Fig. 2) and provided with suitable hearings in the frame. The gearwheel14 is mounted on the wheel-shaft 13, and in turn engages with the pinion 15, mounted on the driving-shaft16. The clutchcollar 17 rotates, with the shaft 16 and is feathered thereon, so as to provide for a longitudinal movement when engaging with the companion clutch-collar 18, loosely mounted on shaft 16. A bevel gear-wheel 19 is rigidly mounted on the loose' member 18 of the pinion 20, rigidly mounted on the inner end of the counter-shaft21. V The clutch-collar 17 is provided with an annular. groove 22, in which is pivoted one end of 'theangle shifting-lever 23, pivoted at 24 to the frame, as. vshown in Fig. 2.

To the opposite end of angle-lever 23 is attached one end of the rod 25', the opposite end of said rod being connected to one end of the bell-crank lever 26, to the other end of which is connected the lower endof the rod 27, broken away in Fig.2, but shown in Fig. 1. The upper end of rod 27 connects with the lower end of the bell-crank lever 28, (see Figs. 1 and3,) to the upper end of which is attached'the front end of the horizontal rod 29. The rear end of rod 29is attached to the shifting-arm 30, one end of which is pivoted to the bracket 31 and is lo-,

cated under the seat and within convenient reach of the driver. The clutch mechanlsm is shown disengaged.

- Throwing the shifting-arm over to the opposite position from that illurtrated in Fig.

3 has the effect of bringing the clutch mechanism into a working engagement.

Upon and near the outer end of countershaft 21 is rigidly mounted the bevel gearwheel 32, engaging-with the corresponding pinion 33, mounted on shaft 34. Figs. 1 and 2.)

(Shown in A companion shaft 35 is provided with suitable bearings in the rocking bracket 36, pivoted at 37 to the fixed supporting-lugs 3S and 39, secured to the frame-work. The companion shafts 34 and35 are connect ed by the tumbling-rod 40, the respective coupling ends of each being provided with the gimbal-joint 41. The outer end of the gimbal-shaft 35 has the pinion 42 mounted thereon, as indicated by dotted lines in Fig. 1.

The bevel gear-wheel 43 is mounted on the vertical reel-shaft 44 and engages with pinion 42. The lower end of the reel-shaft is journaled and supported in the end ofthe rocking bracket 36. The relative position of these parts is shown in .dotted lines on account of the inner dividing-board 45. By this arrangement the desired rotary motion is transmitted to the reel-shaft and the reel 46 mounted thereon.

The reel is adapted to have a vertical ad- ICO justment on its shaftthat is, raised or lowlever 47, the bifurcated end of which is attached to the loose collar 48 on the reel-hub 49, as shown in Figs. 1 and 3. The handle part of lever 47 is mounted on the pivot-bolt 50, which passes through the toothed sector 51 and the hand-lever 52. The sector 51 is also fastened to lever 52 at 53, and moves therewith when the same is shifted. Lever 47 is provided with the usual thumb-latch or pawl attachment 54, engaging with sector 51, and holds said lever at any point in the arc of the circle. The lower end of lever 52 is secured in place by the pivot-bolt 55. This lever 52 is also provided with the thumb-latch 56, which engages with the toothed sector 57, rigidly secured to a convenient part of the frame. It will be seen that lever 47 has the action of a bell-cranklever when shifted to adjust the reel vertically. This lever 47 has an independent movement with reference to lever 52.

The reel-shaft is normally in the vertical position illustrated. Now by throwing lever 52 forward the reel-shaft is correspondingly tilted on its pivot-the rocking bracket 36. The object of this arrangement is to enable the operator to bring the reel into proper position for stalks that may be inclined or leaning, and it will be observed that by a proper handling of the compound levers the reel may be adjusted to .any position within the range of its limit. These compound levers are located back of and in line with the reelshaft, and for this reason are not shown in Fig. 1, (except the bifurcated end of lever 47,) in order to avoid confusion.

The lever 58 (see Figs. 1 and 3) is located to the right of the drivers seat and extends forward to the front of the machine, where it connects with one end of the rock-shaft 59, (see Figs. 1 and 3,) the opposite crank end of said shaft connecting with the upper end of the link-connection 60, the lower end of which is in turn secured to the draft-pole, as shown in Fig. 1 and broken away in Fig. 2. This lever is provided with the thumb-latch 61, Fig. 3, engaging with the sector 62, which provides for the usual locking adjustment. The purpose of lever 58 is to provide for the tipping or tilting of the machine, as may be necessary in accordance with the undulating surface of the ground and the height of the stalks.

The outer or front end of counter-shaft 21 is provided with the double crank 63, (see Figs. 1 and 2,) to which are attached in different planes the connecting-rods 6i and 65. The opposite ends of these connecting-rods are respectively attached to the upper and lower sickle-

bars

66 and 67, lying close together, as shown in Figs. 1, 3, and 5. These sickle-bars have suitable supporting-bearings and are provided with the triangular cuttingknives 68. By this arrangement the sicklebars are adapted to have an alternate reciprocating movement, thus forming a double The sickle-bars are retained in sickle-bar.

proper relative position by the cap-plate 69, provided on the front edge with the overlap ping flange 70, Fig. 5, bolted to the frame, and the angle bed'plate 71, also bolted to the frame. A sprocket-wheel 72 is mounted on counter-shaft 21, (see Figs. 1 and 2,) adjacent to the double crank. A second sprocketwheel 73 is mounted vertically above the first one on the stud-shaft 74, Fig. 1, journaled in the frame. A third sprocket-wheel 75 is lo' cated off to one side and mounted on the nu der roller-shaft 76. (Also shown in Figs. 6 and 7.) A fourth sprocket-wheel a is journaled below the third wheel. The link belt 13 connects this series of sprocket-wheels and transmits the required motion from the driving sprocket-wheel 72. The gear-Wheel 77 is mounted on the stud-shaft 74 and engages with the companion gear-wheel 78, mounted on the stud-shaft 79. The sprocket-wheel 80 is also mounted on shaft 79. The companion sprocket-wheel 81 is mounted on the upper roller-shaft 82. (Also shown in Fig. 6.) By means of the link belt 83 the required motion is transmitted to the upper drivingroller 84, on which runs the upper endless apron 85. The larger companion roller 86, over which the apron 85 runs, is mounted on the shaft 87. The lower or carrying apron 88 is supported by and runs over the terminal rollers 89 and 90, 91 being a guide-roller. The respective ends of the upper roller-shaft 82 are journaled in the upper corresponding ends of the movable frame-boards 92 and 93, located at the front and rear sides of the machine, as more particularly shown in Figs. 6 and 7. The front end of the roller-shaft 82 rests in the elongated aperture 94. in the front part of the main frame, (see Fig. 1,) and is retained in its lowest position by means of the spiral spring 95, inserted in said aperture above the shaft, whereby the roller will yield in an upward direction from any pressure on the under side and be automatically returned to its lowest or normal position when such pressure is relaxed. The ends of shaft 87, on which roller 86 is mounted, are jou-rnaled in the respective lower ends of the movable frame-boards 92 and 93. By this arrangement the carrying-rollers, on which apron 85 is mounted, yield in an upward direction, so as to provide for the passage of the stalks that are carried through between the aprons, the upper apron serving to keep the stalks in a compact form and prevent them from working up over the machine until discharged onto the binding mechanism. The pin 96 (see Fig. 6) is inserted in the movable frame-board 92 near the lower end and projects through the elongated aperture '97 in the main frame to the front side, as shown in Fig. 1. One end of the plate-spring 98 rests on the front projecting end of pin 96, the opposite end of said spring being rigidly secured to the main frame. The adjusting screw 99 provides means for regulating the tension of spring 98. The pin 96 and spring 98 provide for the automaticadjustment of the front end of roller 86. The respective ends of the elliptic spring 100 are attached to the outer side of the rear movable framing board 93, (see Fig.

7,) the back of the spring bearing against the under side of the seat-board 101. This construction provides for the proper working and adjustment of the upper apron and rollers, on which the same is mounted, and for yielding in an upward direction in accordance with the thickness of the object passing underneath and between the aprons, thereby maintaining the required tension. on the lower or carrying apron and keeping the same taut. g

102 represents the different parts of the binding mechanism, which is attached to one side of the machine, as shown in Fig. 1, motion being transmitted to the same from sprocket-wheel 75. 7

As there is nothing new to be claimed in the binding mechanism, a detailed description of the same is omitted.

The curved brace 103 serves to strengthen and stiffen the seat-supporting part of the frame.

The stalks of corn pass in between the dividing-boards, and as they are cut by the double-actin g sickle-bars drop onto the lower apron, which at the receiving-point extends beyond the plane of the upper apron, and are carried under the roller 86 and between the aprons to the terminal point of the same and dropped onto the binding mechanism, from which they arefinally discharged in bundles. The endless aprons are provided at intervals on their contacting surfaces with a number of transverse cleats 104, which assist in moving along the stalks and prevents the fabric from shrinking or doubling inwardly from the edges. 3
