Application filed March .Sl, 1884. Serial No. 126,160. (ModelJ To aZZ whom it may concern.-

Be it known that 1, JOHN J. DEWEY, acitizen of the United States, resident at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Automatic Grain-Binding Harvesters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has relation to harvesters; and it consists in the construction and novel arrangement of parts constituting a novel, simple, and durable machine for harvesting grain and binding the sheaves with cord, all as hereinafter set forth and pointed out in the appended claims.

In the accompanying drawings,the letter A designates the platform-carriers; B,thebinder; O, the automatic trip.

The main frame of the binder B is made of cast-iron, and is formed with bearings for the journals of three shafts, 12, 13, and 14 ,whereof the shaft 13 is midway between the shafts 12 and 14, as shown. The shafts 12 and 13 are represented in Fig. 4 as broken away, but they extend to the rear of the machine, and are there provided with the parts composing the automatic clutch mechanism 0, asshown in Figs. 1, 5, and (3, and as will be more fully explained further on. To the forward end of the shaft 12, which is the main drive-shaft of the binder 1nechanism,is secured the wheel 14, which,when the binding mechanism is in opertion turns in the direction indicated by the arrow. On the inner surface of the wheel 14 is an eccentric cam-track, 15, designed to operate the needle 16, to place the cord 17 around the sheaf, which it accomplishes by means of the lever 18,pivoted at 19 on the shaft 13,and connected by the link 20 with the crank 21 011 the end of the needle-shaft 14.. The upper end of the lever 18 is provided with an antifriction roller, 22, adapted to engage the camtrack 15,before referred to. On the outer surface of the wheel 14: is an eccentric cam-track, 22, and a segment gear, 23, provided for the purpose of operating the shaft 13, havingtlle arms 24.,designed to compress the bundle while being formed and to discharge the sheaf after it is bound. These results are accomplished as follows: On the outer end of shaft 13 is firmly secured the pinion 25 and the arm 26,11aving the anti-friction rollers 27, asshown in Fig. 3. XVhen the binder is set in motion, which is done by the pressure of the grain against the arms 21, as hereinafter more fully described, the shaft 13 is turned in its bearings sufficiently to bring one of the rollers 27 against the cam-track 22. The wheel 14 now commences to turn in the direction indicated by the arrow, and the cam-traek 22, being made concentric for a short distance, has no effect on the shaft 18 until the needle has 0 placed the cord around the grain by the oper' ation of the cam-track 15 on the opposite side of the wheel 14, as before explained. At this point the track 22 begins to diverge from the center and approach the rim, and as it turns 9 5 against the roller it drives the arm 26 out ward, powerfully compressing the bundle while the knot is being tied in the cord. Vhen the wheel 14 has turned far enough to allow the roller 27 to pass off the end of the track 22, thus leaving the shaft 13 free to turn on its bearings, the segment gear .13 engages the pinion 25, giving it a half-revolution,and causes the bound sheaf to be discharged from the binder. The wheel 14 having now made one complete revolution, the binder is brought to rest by means hereinafter explained. A portion of the track 22 at its outer end is made separate, as shown, and is pivoted to the wheel 14, so that it is free to open outward alittle to allow the rollers 27 to pass when the shaft is revolving.

28 indicates the disk for fastening and hold ing the cord. It is provided on its inner surface with a little ratchet-wheel, 29. In acupshaped piece, 30, is seated a dog, 31, which is provided with a spring, 32, and is adapted to engage the ratchet-wheel 29 on the disk. In Fig. 9 the cup-piece is represented arranged in position on the disk, theratchct-wheel and dog being indicated by the dotted lines. The knife 33,for cutting the cord,is secured tothe cup-piece 30 by a screw, 34, so that it can be conveniently removed for sharpening. On the lower edge of the cup-piece is a segment of bevel-gear, 35, adapted to engage a similar segmen t, z, on the plate 36, opposite its hook end 37. The plate 36 is secured to the shaft 38, which has a bearing in the plate 39 underneath, and another in the lug 40 on the main frame. The upper end of the shaft 38 is cranked, and provided with an anti-friction roller, 41, adapted to the grooved guidetrack 42 in the wheel 43. This wheel is secured to the shaft 12, and turns simultaneously with the wheel 14, secured to the forward end of said shaft. The groove 42 runs parallel with the face of the wheel 43 for a short distance, and has no effect on the shaft 38 until the needle has been placed around the sheaf, as already described, placing the cord 17 over the k notter 44 and into one of the marginal notches of the disk 28, as shown in Fig. 2. At this point the groove 42 inclines toward the face of the wheel 43, and whilethis portion ofthe camgroove is passing over the roller on. the shaft V 38 it has the effect to turn the plate 36 suflieiently to cause its hook end 37 to draw the cord 17 directly underneath the knotter in proper position for tying. At the same time the cog end .2 of the bracket, which engages the segment on the cup-piece 30, has the eifect to turn said piece and the disk 28 (which is connected thereto by the dog and ratchet, as before explained) sufficiently to force the cord between the two plates 45 and 46 the dis tauce from one notch in the disk 28 to another. The outside plate, 46, is a flexible spring adapted to accommodate itself to any unevenness of the cord and adjustable in tension by the screw 47, which secures it to the other plate. The operation last described fastens the cord securely preparatory to tying the knot. At this point the groove 42 again runs parallel with the face of the wheel, so that the shaft 38 is held in one position while the knot is being tied.

The construction and operation of the knotter are as follows: It consists simply of a rod,

44, provided at its lower end with a rigid rounded bill form toothed jaw, 48, forming an angle with the axis of the rod 44, as shown, and a pivoted toothed upper jaw, which is free to move up and down in a guide-slot. An upper projection, p, serves to take the strain of the overlying cord off the upper jaw, 49, until it is required to close down upon the cord between the jaws. Cord being stretched across the knotter, as indicated in Figs. 2 4, and 7, and fastened as already described, one revolution of the knotter brings it in the position shown in Fig. 11, the short end of the cord having passed in between the jaws 48 and 49 without their being opened to receive it by any auxiliary machinery, their ends be ing flared apart for that purpose, as shown in Fig. 12. Now, if the cord be cut at 51 and drawn downward off the knotter by its other end the strain of the cord itself on the upper jaw as said cord is drawn off the end of the knotter willbe sufficient to hold the short end 51 of the cord until the loop 52 passes over it, forming a complete knot. The upper jaw, 49, is made longer than the lower one, this construction serving to hold the end of the cord after the loop has passed off the end of the lower jaw, drawing said end through as far as required to make a secure knot. After the knot has been drawn entirely off the upper jaw, relieving it of pressure, it readily lets go the end 51 of the cord. The knotter 44 is journaled in the box 53 on the main frame of the binder, and is provided at its upper end with a bevelpinion, 54, which is turned to tie the knot at the proper time by the bevel cogsegment 55 on the face of the wheel 43 opposite the cam-groove 42. During this period in the revolution of the shaft 12 the compressingarms 24 are also operating to compress the sheaf, as before explained. At this point the groove 42 inclines back to meet the startingpoint, and by this portion of said groove the plate 36 and the cup-piece carrying the knife are moved back to the first position; but the disk 28 remains stationary, being prevented from going back with the cup-piece by the spring 56, which drops into each notch of the disk in succession as it is revolved, and the dog 31, by means of the spring 32, passes freely over the ratchet 29 and drops into another notch of said disk ready to repeat the operation. The knife 33 also, which, as previously explained, followed the disk down out of the way of the cord during the first-movement, is by this movement drawn back across the cord, cutting it off. At the same time the short hook 57 on the plate 36 operates to assist the movement of the cord off the knotter, and the shaft 13 is caused to make a half-revolution, discharging the sheaf, as heretofore explained. The disk 28 and the cup-piece 30 are both journaled on the same shaft 58. A little guide, 59, serves to keep the cord on the knotter.

0, represented more particularly in Figs. 5 and 6, indicates the double automatic trip .the pins 64. The wheel 60 is provided with ratchet-teeth 65, and the clutch-half 63 with ratchet-teeth 66. Both wheels have long hubs 67 and 68, on .which is a sleeve, 69, constructed in two parts and fastened together by the screws 70, crossing the wheel 61 between the spokes, and provided with ratchet-teeth on each end, as shown at 71 and 72. The sleeve 69 is constructed to slide freely on the hubs 67 and 68, guided by the spokes of the wheel 61 and the feather or pin 73.

In the Figs; 1, 5, and 6 the sleeve is represent-ed clutched with the wheel 60, which drives the carriers, leaving the binder-shaft 12 at rest. On the clutch-half 63 is attached a lever-arm, 74, pivoted to said collar at 75, and provided with a roller, 76. On the frame 77 is a lever, 78, pivoted at 7 9, and held down on the stop 80 by the tension spring 81. \Vhen, in revolving, the binder -shaft, with the clutch 63 and roller-arm 74 attached, approaches the position represented in Figs. 5 and 6, the end of the arm 74. comes in contact with the end of the lever 78 at 82,whieh forces the roller 7 6 against the rim 83 on the sleeve 69, pressing said sleeve out of connection with the clutch-half 63 on the binder-shaft 12 and into connection with the chain-wheel 60, as represented in Figs. 5 and 6. The wheel 61 runs continually in the direction indicated by the arrow, receiving its motion through the chains 84 and 85, and intermediate wheel, 86, from the wheel 87, which is connected with the driving-wheel 88 by ordinary bevel-gear.

E represents a device for packing the grain into the binder. It consists of two or more wheels, 89, secured to the shaft 90 and revolved by the chain 10, operating on the sprocket-wheel 91. The packer-wheels 89 are provided with fingers 92, pivoted to them at 93, and so. guided by the track 94 and shield 95 as to project beyond the rim of the wheel, to which they are pivoted, only while passing around the under side, falling back within the rim after having pressed the grain into the binder. This is accomplished by the track 94, which turns the fingers out when their wings 96 come in contact with the end of thetrack at 97, and holds them out until they pass off at the other end. The pins 11 prevent the fingers from falling back too far. The arms D,whieh have the tracks 91 and shields 95 formed entire, are secured to the frame 13 of the binder, and sit out a sufficient distance from the wheel 89 to permit the passage of the fingers 92 during the rotation of the said wheels. \Vhen sufficient grain has been delivered into the binder by the carriers and packers against the cord 17 and the compresser-arms 24 to force the trip-arm N, attached to the end of the compresser-shaft 13, against the lower end of the lever 78, lifting it against the tension-spring 81, off the end of the arm 74, the sleeve 69 is forced out of connection with the wheel 60 and into connection with the clutch 63 on the binder-shaft by the spiral spring 0, which is seated in a recess in the sleeve, thus setting the binder mechanism in motion and stopping the delivery of grain into'it by freeing the wheel 60 from its driver 61. 12 now makes one revolution, and comes to rest again when the levers 74 and 78 come in contact, as already explained, during which time the sheaf is bound, and discharged in the open space f between the binder and the drivewheel.

The cord 17 is carried in the pail a on the drivers platform. It is constructed with an open topand elevated guide, and is placed within convenient reach of the drivcr,to enable him to see and readily disentangle any kink in the cord. Through the guide I) the cord passes, and then runs downward through the guides c and d, back to the guide 6 in the heel of the needle 16, through guides on the back of said needle, and through a perforation near the point of theneedle up over the knotter to the disk 28, where it is always fast.

Y is a device for automatically adjusting the tension of the cord. f, pivoted to the lever 18 of the machine, the lever Z, and the guide 0. The lever Zis pivoted to a fixed bearing, m, on the frame of the machine, its upper or short arm being rounded, and-adapted to press on the cord lying 011 the rounded surface of the guide 0. Any required tension may be given to the cord byadjusting the weight w on the long arm of the lever Z nearer to or farther from its fulcrum, and fastening it in set position. One end of the rodfis pivoted to the level-18 at h. The other end of said rod passes freely through a bearing, is, of the lever Z, and is threaded to receive a nut, a. When the binder is at rest in the position shown in Fig. 7 of the drawings, the lever l is held away from the cord by the nut a on the rod f, so that the cord is relieved of all tension. As soon as the binding mechanism commences to operate, and the lever 18 has moved far enough to draw the nut it away from the lever Z, this lever is caused to drop by the weight w, and tension is put on the cord. The device may be set to let the tension on at any required time or point during the operation of the needle by manipulating the nut a. In the construction illustrated the rake-head extends forward through the swivelbearing of the driving-chain next the sickle, and is provided with a rake-finger at its pro jecting end forward of said chain, in order to catch the butts of the grain near the sickle.
