Application filed May 18, 1997. Serial 110.374.4411.

To all wig-omit may concern Be it Known that I, VVILLIAM DOERING, a citizen of the United States, residing at Nappanee, in the county of Elkhart and. State of Indiana, have invented a certain new and useful Improvement in Grain- Shocking Devices, of which the following is a specification.

This invention relates to devices for shocking' grain or the like, and has for its object the production of a new and improved deviceof this description.

Referring to the accompanying drawings,

} bundles of grain from said binder will be delivered to the shocker.

may be made in any desired manner. vAs herein shown two arms 3 and 4, (see Fig. 2), are connected to the frame 1, and are joined to a connecting piece 5 which is movably attached to a holding piece 6 connected with the binder. This connection is prefer ably by a ball and socket joint 50 as to per- This connection mit relative movement of the binder and the shocker, due to the unevenness of the surface over which the machines travel. A brace rod 7 is connected with the arm 4 and with the binder. A receiving device 8 for receiving the grain. is located so that when in its initial position it'will receive the grain from the discharge 9 of the harvester. This receiving device may be arranged in any, desired manner, and as herein shown con-* the grain or bundles, the butts or lower ends thereof preferably resting upon a platform 10 fastened to the frame. .The receiving device has a two-part support consisting of the part 11 and the arm- 12, the part-11 being rotatably or movably mounted upon the arm 12 so, that the fingers inay'be moved from a horizontal to a vertical position under-predetermined conditions. The support for the receiving'device is supported bya guiding device 13 along'which it drives from its initial to its discharge position. As illustrated in Figs. land 2 this guiding device rises from the initial position of the receiving device to the point 14, which is the highest point. The guiding device then changes direction as shown in Fig.

sists of a series of fingers preferably s positioned to receive the upper ends 'of 5, and is connected to the frame. The connection of the support fort-he receiving device to the guiding device may be arranged in any desired manner,

flange 15, and the part 11 of the support is provided with engaging parts which engage both sides of this flange. As shown in Fig.

"As herein shown (Figs. 4 and 8) the guiding device is pro-' 'vided with a laterally pro ecting part or 8 these engaging parts consist of wheels 16 for the purpose of reducing friction. In view of this construction of the guiding de-' vice and the connection of the support for the receiving device thereto, it'will be seen that when the neceiving device reaches the point 14 and. passes down the inclined part of the guide'the receiving device will be turned from its horizontal to itsvertical or discharge osition.

Some suitable means is provided for moving the receiving device to its discharge position. As herein shown the receiving device is connected with the driving wheel 17 of the machine. The arm 12, is connected t'o-con'necting piece 18 attached to the shaft 19 so as to rotate therewith. This shaft is mounted upon the frame and is provided -with a beveled gear 20 adapted to engage a gear 21 on the shaft- 22 which shaft is operatively connected with the driving wheel 17 by the chain 23. A spring 24 is connected at one end to the frame 1 and at the other end to the connecting piece 18, and hence to the receiving device 8. This spring helps to move the receiving device to its discharge position, and therefore acts as a brake when the receiving device is being returned to its initial position to take oi? the shock of the blow due to this return. The support for the receiv'ig device. is provided with a latch or lock by means of which it is locked in its initial position. This latch or lock is shown clearl in Fig. 7, and comprises two engaging or

interlock ing parts

25 and 26. The interlocking 1).". rt or latch :26 is normally held in engagement with the part 27 by the spring 27. \Vhen it is desired to move the receiving device to its discharge position the interlocking parts are disconnected and the

gears

20 and 21 are connected together. Home suitable means is provided for this purpose. As herein shown a shaft. or rod 33 is rotatabl v mounted upon the frame and is provided with an arm 29 (see Fig. 2) which is connected by. a connecting piece 30. which runs to a lever or other suitable handle device 31 in position to be operated by the operator of the harvester. It will be seen that by moving this handle 31 the rod 38 will be rotated. The rod 38 provided with an arm 39 which is connected by connecting piece 4 with the sliding member 41 connected to:

the frame at 42 so as to be free both to slide and to move about the point 42. This sliding member (see Fig. 3) is connected to the frame by a spring 43 and is bent at the end or so formed as to be provided with two engaging faces 44, 45. The engaging face 44 in its initial position engages a part or link 46 pivot-ally connected with a disk 47 by the pivot or wrist pin 48. The link 46 is connected with the bolt 49 which operates the clamping mechanism for the shockhereinafter described. The disk 47 is connected with t mutilated gear 50 adapted under predetermined conditions to engage the gear The gear 50 and associated parts are connected to, a bracket 52 which is connected to the frame 1. The mutilated portion of the gear 50 is opposite the gear 51 (see Fig. 10) when the parts are in their initial position. When the rod 38 is rotated it moves the sliding member 41 in thedirection of the arrow (Fig. 3). This produces a partial rotation of the disk 47 and the gear 50 so as to bring the teeth of the gear 50 into engagement with the teeth of the gear 51. The gear 51 is connected with the driving mechanism in any desired man;

ner. As herein shown the haft is connected withthe main driving wheel, being in this instance a part of the axle thereof. After the mutilated gear engages the gear 51 the disk, 47 is rotated by the shaft- 70 in the direction of the arrow, Fig. 3. The sliding member 41 at this stage is released by the operator and moves back to its ini tial position. as shown in Fig. 3, and remains in this position until the link 46 makes a half revolution, whereupon the end thereof engages the engaging face 45. The further rotation of the disk moves the sliding member 41 about its pivot 42. The sliding member 41 is connected by link 53 with the projection 54 on the rod or shaft 28.

. and this movement thereof rotates the rod or shaft- 28. The link 53 has :1 slotted connection with the sliding member 41. and with the part 54 so that the shaft QS can be returned to the position shown in Fig. 6 without att'ecting the position of the sliding member 4]. As the disk 47' continues to rotate the link 46 becomes disengaged from die sliding member. after the shaft 28 has been proper-l moved. and said member is returned to its initial position by the spring 43 it being stopped in its initial position by a suitable stop The rod 28 is provided with a projection. cam or eccentric portion which engages the latch or interlocking part 26 (see Fig. 7). It will be seen that when the shaft is rotated it will move this part as and disengage the receiving device. A spring 33 is connected with the rod '28 and with a fixed part. of the frame so as to return the rod to its initial position when it is relcasethas hereinafter described. The rod 28 is also provided with a projection or cam part 34. (see Fig. (3) which engages the gear shitting device 35 provided at its ends with projections which tit in a groove 36 on tllc hub of the gear 21. This gear is slidablv mounted on the shaft 22-. When the rod 28 is in. its initial position the projection 34 engages the gear shifting device 35 and holds it out of mesh; with the gear 20. Vhen the rod is rotated and the receiving device released,

the cam 34 releases the gear shifting device and it is moved by the spring 37 so as tobring the gear 21 into engagement with the gear 20, thus simultaneously with the release of the receiving device connecting it with the driving mechanism. These gears are kept. .in engagement until the receiving device reaches its discharge position, in view of thefact that the spring'37 pulls the gear shifting device against, the projection 34 when in its angular position with such. force as to prevent the spring 33 from returning the shaft 28 to its initial position, as shown-in Fig. 6. When the receiving device.- reaches its discharge position a projeci fi 9 1 theg erflfl .F 5 en s preferably slotted as shown in Fig. 4. As-

to its initial position so as to cause the pro- ,-"ject ion 34 to hold said arm in its initial position.

porting part 11 for said Associated with the receiving .device 8 is a gripping device for gripping the grain so as to hold it in deposited upon the ground. This gripping device is arranged to grip the grain by an encircling gripping movement like the closing of the hand as distinguished from the closing of a pair of pliers. The circular gripping-action binds the bundles together like a flexible band, such as a rope, and thus secures the proper clamping and holding action with a comparatively small pressure. As herein illustrated there is provided a se ries of gripping

portions

57, 58, 59 hinged together. The

portions

57 and 58 are fastened to the receiving device in any suitable manner, as. for example, by means of the rods 60. These portions are pivotally connected" together at- 61, one portion being sociated with the portion 59 is an operating lever .62 connected therewith by thelink 63.

This lever is pivotally connected to theframe'at 64. A spring normally tends to hold the parts open in the position shownin dotted lines in Fig. 4. The parts are moved to their closed or gripping position bv the bolt 49 actuated by the link 46 and disk 47. When the disk 47 is rotated as before described, the bolt 49 is projectedf and engages the lever 62. so as to move it and the

portions

57, 58, and 59 to the'gripping position. hen moved to this position and before the return of the bolt by the further rotation of the disk 47, a pivoted arm 66 engages the lever 62 so as to hold the parts.

in their-gripping position. The portion of the bracket 52 upon which the bolt is mounted is preferably provided with a suitable brace to hold the parts more rigidly in posit-"ion. The pivoted arm moves with the receiving device, and is pivoted to the supreeeiving device: A spring 67 normally presses said arm outs wardly. thus tending to rotate it about its pivot 68 and force it toward the lever 62. This pivoted arm is preferably notched at the end so that when the lever 62 sliding along it comes opposite the notch the spring will move the arm so as against retraction.

After the parts of the gripping device are moved to their gripping position the receiving device is moved along the guiding device 13 by the rotation of the shaft 19 as previously described. When the support for to hold the lever the receivingdevice reaches the point 141,011

the guiding device the further movement thereof causes thepart- -11 to rotate about the part 12, and turn the proper relation until it can'be receiving device from a horizontal to a vertical position, the parts then being in their discharge position. When in this position the pivoted arm 66 strikes an engaging device 69 (see Figs. 1 and 2) which moves the pivoted arm to one side and permits the spring 65 to instantly open the gripping device so as to release the grain. The gripping device and the receiving device are in the position shown in Fi 3. In view of the fact that the machine is moving in the direction of the arrow in said figure, it will be seen that there is; nothing back of the shock which, would tend to topple it over, and hence even if the parts were left in this position the shock would in -no manner be disturbed by the onward movement of the machine. After the shock is discharged it is returned to its initial position. This return is accomplished by conmeeting it with the driving wheel when in this position. The returning mechanism comprises. an arm 7L in position to be struck by the support of the receiving device,.or some part. associated therewith. This arm 71 is connected to a shaft 72 mounted in a suit-able bearing on the frame, and operatii'ely connected in any desired manner, as by means of the chain 73, with a sleeve 74 loosely mounted on the driving shaft. This sleeve is provided with a clutch member 75 adapted to engage a clutch member 76 retating with the driving shaft. Means is.

provided for connecting these clutch members when the receiving device reaches its discharge position. As herein shown a shaft 77 is mounted upon suitable bearings and is provided at one end with a lever arm 78 to which is attached a spring 79 which is engaged by the bent end 80 of the lever 71, the bent end 80 of said lever being in turn engaged by the projection 81 on the supporting part- 11 for the receiving device. The

shaft 77 is provided at'the other end with I an arm 82 which is provided at the end with a fork 83 working in a groove in the sleeve 74. It will thus be seen that when the receiving device strikes the lever 71 and said lever strikes 'the spring 79 and the arm.78,

the shaft 77 is rotated so as to move the fork 83 to force the two

clutch members

75 and 76 into engagement. This connects the arm 71 directly with the driving shaft and causes av rotation of the shaft 72. The arm 1s thus lifted up carrying with it the receiving device. hen the receiving device reaches the point 14 the clutchmembers are disengaged and it is then freedand moves down the inclined guide to its initial position.

The freeing of the clutch members may be a-ccr-mplished in any desired manner. herein shown, the clutcli member 75 is provided with apin or projection 84. Afixed part 85 is provided with a beveled face 86 arranged so that the pin 84 eng g s 581d bev- 'eled face when the lever 71 has been lifted clutch members to become disengaged, the

parts then being ready to again return the receiving device. Some means is preferably provided to take up the blow of the receiv-- ing device as it drops. it were, to its discharge position. As herein shown a spring 87 is fastened to the frame and projects in the path of the bent portion 80 of the arm 71. This spring also holds the arm 71 in position to receive the receiving device.

\Vhile the receiving device is being moved to its discharf 'c position some means should be provided for retaining the grain that may be discharged from the harvester before the receiving device returns. As herein shown there is illustrated one form of retaining device which consists of a series of fingers 88 upon which the grain is received. These tingers are connected to a cross piece 89 which is movably connected with an arm 90 pivoted at 91 (Fig. l) to the frame. Attached to one of the fingers 88 is a supporting part 92 which is pivoted at 93 to the frame. ('cnnected with this supporting part is a rod 9% surrounded by a spring 95, said rod passing through an opening in a guiding piece 96 which limits the movement of the spring but permits the movement of the rod. A controlling part 97 is also pivoted at. 93 and is provided with a bent portion 98 which engages the supporting piece 92 (see Figs. 1 and 3). This controlling part is connected by a cord or other suitable flexible connection 99 with a grooved wheel 100. fastened to the end of the shaft 19. This cord passes over

suitable pulleys

101 and 102 for the purpose of changing its direction. \Vl-ien this shaft l9 is rotated during the process of moving the receiving device to its discharge position the cord or flexible connection 99 is wound upon the grooved wheel 100 and moves the controlling part-9T so that the bent end 98 engages the part 92. the further movement thereof forcing the parts from the position shown in dotted lines in Fig. l to the position shown in full lines. the spring 95 being thereby compressed. When in this position the arm 90 rests upon the support 103. and is held in this' position against the force of the spring 95 by the pivoted holding piece 10% (see Fig. 11). This holding piece is pivoted at 105 and is provided with a. spring 10o'which tends to move it to its holding position. It is also provided with a beveled face 107 which is engaged by the arm 90 as it moves down to its operative position, such engagement moving the holding piece 104 to one side. said holding piece being moved back by the spring.after the arm has passed. When in this position the retaining device retains the grain discharged from the harvester. When the receiving deinitial position and the fingers 8 come under the retaining device the part- 11 of the support for the receiving device, or some part of the holding piece 104 and moves'it to one side so as to release the arm 90. The spring 95 then acts to movg the parts of the retaining device to the position shown in dotted line's in Fig. 1, the grain slidingfrom the fingers 88 upon the fingers 8 of the receiving device. The spring 108 (Fig. 3) tends to move the parts to take up the slack in the cord or cable 99. A stop 109 on the frame 3 stops the receiving device when it reaches its initial position. and it may also be used to hold it down while the gripping device is being operated.

Briefly described the operation of the apparatus herein shown is as follows: \Vhen sutlicient grain or bundles of grain are received in the recehing device the operator moves the lever 31. This movement through the intervening mechanism hereinhefore described causes the mutilated gear 50 to en gage the gear 51 and the disk 47 is rotated so as to move the bolt 49 against the lever (32 and move the gripping device to its gripping position. The further movement of said disk acts through the intervening mechanism to move the

gears

20 and 21 into engagement. thus causing a rotation of the shaft 19. This moves the receiving de vice and the gripping device alon'g the guideway to the point 14-, whereupon the receiving-device is tilted to a vertical pOsition. the gripping device released by the engagement of the pivoted lever 66; and the engaging piece 69, and the several parts of the gripping device suddenly moved outof the way. The shock of grain is then deposited upon the ground. The further movement of the receivingdevice causes a l movement of the shaft 7 7 so-as to throw the l clutch members 7 5 and 76 into engagement. 5 r he receiving device is thus connected with l the driving wheel and the driving. shaft through the arm 71, and said armis lifted so as-to lift the receiving device back up onto the guiding device. The clutch membears are then automatically released and the receiving device slides b gravity downthe incline of the guiding evice to ts initial position. The movement of the shaft 19 which causes the receiving device to move [to its discharge position through the grooved wheel 100 and the cord or r0 e 99, controlling device 97 and associate parts, moves the retaining device to its operative position so as to catch and hold any gram that may be discharged from'the harvester. When the receiving device returns to ts nitial position it releases the reta-ini de'v :e by engaging the lever 104, and sin vice is moved to its inoperative position by vice moves from its discharge position to its associated therewith, strikes the lower end ion retaining dethe spring 95, thus discharging the grain re- I tained by it upon the receiving device. It

will thus be seen that in this constructionthe operator gives the initial movement, and

1 this initial movement need only be sufi'lposition, returns it to its initial position,--

moves the retaining device to its operative position, and then to its inoperative position so as to deposit the material retained byv it upon the receiving device. It will further betseen that the gripping is donebefore the receiving device is moved, and that the complete cycle of operation is automatic,
