Application led July 5, 1912. Serial No. 707,812.

To all 'whom t may concern:

Be it known that I, Louis ANDERSON, a citizen of the United States, and resident o f Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Harvesting-Maclnnes, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to harvesting machines, and more particularly to those having provision for reaping and binding grain and for collecting the bundles and deposit ing them upon the ground in the form of a shock.

The present invention contemplates improved mechanism for controlling the operation of the several parts.

rllhe object of the invention is topro-vide a harvesting machine which shall be of simple construction and reliable in operation.

The invention is exemplified in the structure to be hereinafter described, and which is illustrated in the accompanying drawings, whereinl Figure 1 is a side elevation of a harvesting machine embodying the features of im- )rovement provided by the invention; Fig. 2 is a detail plan view of the same; Fig. 3 is a detail rear elevation of the machine, the rear end sill of the frame being omitted and some of the parts being shown in section; Fig. 4 is a detail front elevation of the ma.- chine, the `front end sill of the frame being omitted and the adjacent portions of the side sills being shown in section; Figs. 5 and 6 are sectional views taken on the lines 5 5 and 6 6 respectively7 of Fig. 2; Fig. 7 is a detail sectional view taken on the line 7-7 of Fig. 6; Fig. 8 is a detail plan sectional view taken on the line 8-8 of Fig. 4; Fig. 9 is an end elevation of the bundlegripping mechanism, the position of this view being indicated by the arrow 9 on Fig. 2; Fig. l() is similar to Fig. 9, but shows the parts in the position which they occupy when holding the bundle; and Fig. l1 is a detail rear .elevation of the machine showing the parts of the bundle transfer mechanism in the position which they occupy immediately after releasing a bundle and permitting it to fall into the shock-forming mechanism. Y

r)The parts of the machine are shown as being associatedupon an oblong rectangular frame comprising the side sills 25, 26, the

rear end sill 27 and the front end sill 28. The frame is principally supported upon a traction wheel 29 which is located at about the mid-length of the frame between the side sills 25, 26.

The bundles of grain are formed in the usual way upon an inclined table shown at 30. This table is supported over the frame, as by the uprights 3l, 32, 33 and 34. Belt conveyer mechanism for delivering the loose grain to the table 30 is shown at 3,5. During the formation of the bundles, the loose grain is forced against a movable trip arm 36 by the packers 37 and 38, and is tied by the knetter mechanism comprising the needle arm 39 and the knotter shaft 40. lllhen a sufficient amount of grain for the formation of a bundle has been forced against the trip arm 36, this arm is depressed. As is usual in the operation of harvesting machines, the movement of this arm automatically arrests the operation of the packers 37, 38 and sets the knetter shaft 40 in motion.

A pair of guide arms 42, 43 are provided for receiving each bundle of grain after it is tied. As shown these arins project laterally from the lower edge of the table 30. Each. bundle of grain, after being completed, is pushed outwardly upon these arms. For this purpose an arm 41, carried by the knotter shaft 40 and projecting radially outward therefrom, is preferably provided.

Most desir-ably the tying of each bundle of grain and the movement of the bundle outwardly upon the guide arms 42, 43 by the engagement therewith of the arm 41, are both completed during a single rotation of the knotter shaft. To this end the arm 41 is preferably sol positioned upon the knotter shaft as to engage the bundle during the latter part of each rotation of the shaft.

Power for actuating the several parts of the machine may be supplied in any convenient way, as from the tractionwheel 29. As shown, a countershaft 44 extends transversely between the sills 25, 26 and is ournaled upon the inside faces of these sills at its opposite ends. rlhis countershaft is operatively connected with the traction wheel 29 by a sprocket chain 45. This sprocket chain turns over` a sprocket wheel 46 mounted with the traction wheel and over a sprocket wheel 47 mounted on the countershaft. A second shaft48, connected to the countershaft 44 by beveled gears 49,

50, extends to the forward end of the machine for actuating the knot-forming mechanism as also the reaping mechanism (not shown). A pair of beveled gears 51, 52, most clearly shown in Fig. 8, are mounted on the shaft 48 adjacent its forward end. The gear 51 is fixed upon the shaft 48 to rotate with the shaft. The gear 52 is normally loose upon the shaft. The gear 51 serves to transmit power to the packers 37, 38. The gear 52 serves to transmit power toV the knotter shaft 40.

A beveled pinion 53 meshes with the gear 51. This pinion is mounted upon the lower end of a flexible shaft 54. The higher end of this shaft is connected by beveled gears 55, 56 with a shaft 57 which actuates the packers 37, 38 in the usual way. The lower end of the shaft 54, adjacent the pinion 53, is journaled in a swinging arm 60 (Fig. 8),

-whereby the pinion 53 may be moved into .and out of engagement with the beveled gear 51. As shown the arm 60 is mounted upon an upright pivot 61 which rises from a bracket 62 carried by the side sill 26.

For operatively connecting the beveled gear 52 with the knotter shaft 40 a shaft 63 is provided. This shaft has beveled pinions 64, 65 mounted upon its opposite ends for meshing with the beveled gear 52 and with a beveled gear 66 on the knetter shaft 40, respectively. A ratchet wheel 67 is fixed upon the shaft 48 adjacent the hub of the beveled gear 52. A pawl 68, mounted upon the back of the beveled gear 52, serves to engage this ratchet wheel when the vknotter shaft is to be driven. The pawl 68 vis normally held out of engagement with the ratchet wheel 67 by a cam finger 69. This cam finger is preferably carried by the swinging arm 60, whereby when the arm 60 is swung to move the beveled pinion 53 out of engagement with the beveled gear 51 and thereby arrest the operation of the packers 37, 38, the cam finger 69 is withdrawn from beneath the pawl 68. When the arm 60 is moved back to its original position to restore the pinion 53 to its position of engagement with the gear 51, the cam linger 69is again brought into the path of the pawl 68. The pawl 68 will then be raised out of engagement with the ratchet wheel 67, to arrest the movement of the knotter shaft 40, as soon as the pawl reaches the cam during the turning of the shaft.

A toggle 70 serves for swinging the arm 60. This toggle is connected at one end to 'the swinging arm 60 and at the other end to a fixed part of the frame of the machine, as to the cross tie 71. A shipper rod 72 is connected at one yend to the joint of the toggle 7 0 and at the other end to the crank arm 73 of a rock shaft 74. The rock shaft,

74 extends longitudinally beneath the table V30. It is turned in one direction to release the pinion 53 from engagement with the beveled gear 51 and to set the knot-forming shaft 40 in motion by the movement of the trip arm 36 heretofore described. To this end the trip arm 36 extends downwardly through the table 30 and is mounted at its lower end on a rock shaft 75. The rock shaft 7 5 carries a crank arm 76 for engaging a yoke 77 which is carried by the rock shaft 74 and projects radially therefrom. Preferably the crank arm 76 is jointed, as shown at 58, whereby its lower end will yield in one direction. As shown the crank arm and yoke are so proportioned in length that when the trip arm 36 is depressed, the crank arm'76 engages the cross arm of the yoke'7 7 to swing the rock shaft 74, and then passes beyond this cross armprand into the space inclosed by the yoke. 'This arrangement Vpermits the rock shaft 74 to be restored to its original position in advance of the restoration of the trip arm 36. When the trip arm 36 is to be restored, the jointed arm 76 flexes to permit its lower end to pass over the cross member of the yoke 77.

A cam 78 mounted on the knetter shaft `40 serves to move the rock shaft 74 in the The-shock-forming mechanism comprises a cradle generally designatedby the numeral 83. This cradle serves to receive the bundles of grain and to retain them until a'suflicient number for the formation of a shock have accumulated therein. For transferring the bundles of grainfrom the arms V42, 43, to

the cradle V83, a swinging arm 84, carrying a fork 86 is provided. As shown this arm, as also an operating arm extending parallel therewith, is mounted in the head 87 of a rotatable post 59. As a means for supporting the rotatable post 59, it is shown as being extended-through a tubular standard 88. near the rear lower corner of the table 30.

VAs shown, it is carried by a bracket 89 mounted on said table. y

The fork 86 comprises a forked abutment member 9() and a similarlyvformed member 91.A To permit the bundle -to be turned end for end the fork 86 is rotated upon its axis. To this endthe abutment memberA 90 has Va vertically'extended stein 92. This stem extends thro'ughyand is rotatably mounted in a journalbearing 93 located upon the outer end of the armA 84.

This standard is preferably located grasping fr.

The grasping member 91 is pivoted at V94V 139- upon a bracket 95 carried by the abutment member 90. A spring 96, reacting between the head of the member 91 above the pivot 94, and a second bracket 97 carriedby the abutment member 90, serves to normally hold the parts of the fork in open position.

The arms 84, 85 normally stand in the position shown in 'Fig.`5 of the drawings, whereby the abutment member 90 is held in a suitable position to serve as astop against which the bundle of grain is moved by the arm 41. The grasping member 91 is preferably closed upon the bundle of grain by rotating the arm 85. As shown, the arm 85 carries a crank arm 98 adjacent its outer end, and this crank arm bears upon a cam member 99 which is carried by the bundle grasping member 91. For holding the grasping member 91 in closed position during the axial rotation of the fork 86, a cam track 100 is provided for engaging the head portion 101 of the grasping member 91. The cam track 100 is conveniently carried by a bracket arm 102 which in turn is mounted upon the outer end of the arm 84.

To prevent the bundle of grain from being thrown to the rear of the shock-forming cradle 83 when it is released from the fork 86, provision is preferably made for releasing the bundle after the fork has been brought to rest in a position above the cradle. This is conveniently accomplished by making the cam track 100 sectional, an end portion 103 of the same being hinged, as at 104, to swing upwardly. For controlling the swinging of the end portion 103 of the cam track 100, a lever 105 is pivotally mounted upon the bracket 102 intermediate its ends. One end of this lever is connected to the part 103 by a link 106. The other end of the lever 105 is connected by a link 107 to the crank arm 98. A rotation of the arm 85 in the proper direction to raise the crank arm 98 also raises the part 103 to permit the bundle of grain to fall from the fork 86. For rotating the fork 86 to turn the bundle end for end a crank arm 108 is mounted upon the higher end of the stem 92. A link 110 connects this crank arm with a Vfixed part of the frame of the machine, as the bracket 109.

Tnasmuch as a bundle of grain is carried in the fork 86 during its movement in one direction only, the arm 84 is preferably eX- tended in rear of the head 87, and a sliding counterweight 111 is mounted on this part of the arm. The sliding of this counterweight, as also the turning of the arm 85, is preferably effected by means of a plunger 112 which extends vertically through the post A bell crank lever 113, pivoted at 114 upon a part of the head 87, is employed for operatively connecting the plunger 112 with the sliding counterweight 111. One arm of this bell crank lever has a pin and slot connection l115 with the plunger 112. The other Varm of the bellcrank lever 113 is connected to the counterweight 111 by a link 116. A crank arm 117 mounted on the arm 85 adjacent itsiinner end, is connected to the plunger 112 by a link 118. The arrangement provides that a vertical reciprocation of the plunger 112 within the post 59 simultaneously moves the counterweight 111 upon the extended rear end of the arm 84 and turns the arm 85 to cause the fork 86 to grasp or release a bundle of grain. By this means the counterweight 111 is moved outwardly whenever the fork 86 receives the weight of a bundle of grain, and is moved inwardly whenever the fork 86 is relieved of the weight of a bundle of grain.

A pair of cams 119, 120, are provided for reciprocating the plunger 112 and for turn ing the tubular post 59, respectively. As shown, these cams are formed integral and upon the opposite faces of a cam plate 121. The cam plate 121 is fixed upon a sleeve 122. rIhis sleeve is loosely mounted on the countershaft 44. Clutch mechanism is provided for causing the sleeve 122 to turn with the countershaft 44 when the bundle transfer mechanism is to be operated. As shown, this clutch mechanism comprises a ratchet 123, a pawl 124, and a pawl lifter 125. The ratchet 123 is formed upon the hub of the sprocket wheel 47 and moves continuously with the sprocket wheel 47 and with the shaft 44. The pawl 124 is carried by the sleeve 122 and coperates with the ratchet 123 to turn the sleeve 122 with the counter'- shaft 44 through one complete revolution whenever the bundle transfer mechanism is to be operated. The pawl lifter 125 takes the form of a cam finger having one end resting upon the hub of the ratchet wheel 123. This cam finger is pivoted intermediate its ends upon a fixed part of the frame of the machine, as upon the bracket 126 (Fig. 7). Normally the pawl 124 rests upon the free end portion of the cam finger 125, and is held thereby out of engagement with the ratchet 123. A spring 1259, reacting between the cam finger 125 and the bracket 126, may be used to normally hold the cam finger in position to support the pawl.

When the bundle transfer mechanism is to be operated, the cam finger 125 is swung about its pivot to withdraw its free end from beneath the pawl 124. For this purn pose the cam finger is connected by a link 127 to the crank arm 128 of a rock shaft 129. This rock shaft extends beneath the table 30 to the forward end of the machine. At its forward end it carries a crank arm (Fig. 4). This crank arm extends upwardly to a position adjacent the knotter shaft 40 and coperates with a cam, as 78, mounted on the knotter shaft. The rock shaft 129 is thereby oscillated to withdraw ian lac

the cam linger 125 from beneath the pawl 124 at a predetermined point in the movement of the knotter shaft. )When the sleeve 122 has been turned through one complete revolution, the cam linger 125 having been returned to its original position by the spring 125, the pawl 124 rides upon this cam linger and is lifted thereby out of engagement with the ratchet wheel 123, and the sleeve 122 comes to rest.

A pair of vertically movable plungers 131, 132, are provided for coperating with the cams 119, 120, respectively. Each of these plungers has its lower end bifurcated, as indicated at 133 (Fig. 7), to straddle the sleeve 122 and to be guided thereby. Cam rollers 134, 135, carried by the plungers 131, 132, respectively, coperate with 'the cams 119 and 120 for effecting a vertical reciprocation of the plungers 131 and 132 during the turning' of the sleeve 122.

VThe plunger 131 serves for vertically reciprocating the plunger 112. To this end the plunger 131 has its higher end operatively connected to a lever 136. This lever is pivoted intermediate its ends upon a fixed part of the frame of the machine, as at 137 (Fig. 3). The other end of the lever 136 is connected to the lower end of the plunger 112 by a link 138.

The plunger 132 serves for turning the post 59 within .the standard 88. To this end a crank arm 139, most clearly shown in Fig.

2, is mounted upon the lower` end of the Y post. This crank arm is connected to one end of a lever 140, as by a link 141. The lever 140 is pivoted intermediate its ends upon a fixed part of the frame of the machine, as upon the bracket 142 (Fig. 3). The other end of the lever 140 is operatively connected to the plunger 132, as by a bellcrank lever 143. This bell-crank lever oscillates in a vertical plane and is pivotally mounted upon any convenient part of the frame of the machine, as upon a bracket 144, secured to the under side of the table 30.

Preferably the swinging of the lever 140 serves to restore the trip arm 36 to vitsrupright position. For this purpose a lever 145 maybe provided. As shown, this lever is pivotally mounted upon the under side of the table 30, as at 146 (Fig. 5). One end of the lever extends into the path of the lever 140, to be engaged by the last-named lever when the post 59 has been rotated to remove a bundle of gra-in from the arms 42, 43. The other end of the lever 145 is connected to a crank arm 147 of the rock shaft 75 by a link 148.

The ope-ration of the machine, as shown, is as follows: As' the machine is drawn over the ground the countershafts 44 and 48 are continuously rotated by the turning of the traction wheel 29. Loose grain is fed to the table 30 by the belt conveyer mechanism 35.

arm 60 (Fig. 8) by flexing the toggle 70.Y u

engage-V This withdraws the pinion-53 from ment with the beveled gear 51 and arrests the action of the packers 37, 38. It also withdraws the cam finger 69 from beneathV the pawl 68, whereby the pawl is permitted to fall into engagement with the ratchet wheel 67 to rotate the beveled gear 52 and drive the knotted shaft the knetter shaft 40 actuates the needle arm 39 to tie a bundle of grain.V l/Vhen the bundle has been completely formed, it is engaged by the arm 41 (Fig 5) and thrust out 40. Y The turning of upon the arms 42, 43, and into-engagement Y with the abutment member' 90 of the fork 86 of the bundle transfer mechanism. During the formation of the bundle of grain the cam 78 swings the bell crank lever 79, and turns the rock shaft 74 to restore the yoke 77 to its normal position and to restore the arm 60 (Fig. 8) to that position in which the pinion 53 is engaged with the beveled gear 51. This renews theactuation of the packers 37, 38, and the cam linger 69 having been moved back into the path of the pawl 68, this pawl will be raised out of engagement with the ratchet wheel 67 to arrest the movement of the knetter shaft when'the beveled gear 52 has been turned through Y one complete revolution. When a bundle of grain has been brought against the abutment part 90 of the fork 86 of the bundle transfer mechanism, the cam 78 will have engaged the lever 130 (Fig. Y4) to turn the rock shaft 129 and withdraw the pawl lifter 125 (Fig. 6) from beneath the pawl 124. The sleeve 122 and camsV 119 and 120 are thus actuated through one complete revolution and drive the bundle transfer mechanism. The cam 119 first causes the plungers 131 and 112 (Fig. 3) to be shifted to close the part 91 (F 9) upon the bundle and to move the counterweight 111 outwardly upon the extended rear end portion of the arm 84. The cam 120 then actuates the plunger 132 to rotate the post v59 and swing the fork to a position above the shock-forming cradle 83. During this movement of the fork 86, the bundle Vof grain is turned end for end by the turning of the fork upon its pivot, this being accomplished by the connection of the crank arm 108 with the fixed part 109 (Fig. 1) through the link 110. As the bundle is being moved to a position over the cradle 83,

theparts of the fork 86 are held in closed position by the engagement of the cam track 100 (Fig. 10) with the head 101 of the grasping member 91. IVhen the bundle of grain has been brought to rest in a position above the cradle 83, the cam 119 again shifts the plungers 131 and 112 to move the counterweight 111 inwardly and raise the movable end portion 103 of the cam track 100 Jfig. 11) to permit the parts of the fork 86 to be opened by the action of the spring 96. The bundle of grain thereupon falls into the shock-forming cradle 83. The cam 120 now actuates the plunger 132 to return the fork 86 to its position for receiving another bundle of grain. As soon as the fork S6 has removed one bundle of grain from the arms 42, 43, the trip arm 36 is restored to its upright position by the engagement of the lever 140 with the lever 145 (Fig. 2). This permits the operation of the bundle forming mechanism to be continued for the forma tion of a new bundle, while the previously formed bundle is being transferred to the shock former 83. In event the new bundle has been completed by the time the fork 86 is returned to its bundle-receiving position, the sleeve 122 will continue to rotate and the operation of the parts will be repeated without interruption. If a new bundle of grain has not been completed at the time indicated, the pawl 124 will ride upon the cam linger 125 when the sleeve 122 has been turned through one complete revolution, thereby bringing the parts of the bundle transfer mechanism to rest until the trip arm 135 is again depressed. When a suiiicient number of bundles of grain for the Jformation of a shock have been transferred tothe cradle S3, this mechanism will be operated to deposit the bundles upon the ground in the form of a shock in a manner which is fully described in my copending application for patent on shock former for harvesting machines, Serial No. 693,984, sled April 29, 1912.
