Application filed J'anuary15, 1927. Serial Naieisss.

The present invention pertains to a novel machine constructed to accompany a grain binder and to receive sheaves'theretrom Wl'llCll are formed into the shocks and delivered to the ground by the machine.

The novel machine comprises a recelver into which the sheaves are thrown from the binder. The receiver sets the sheaves upright on the floor ot' the machine, from which they are delivered by suitable mechanism to the ground.

More specifically the machinecomprises, in addition to the receiver, a floor provided with a longitudinally moving conveyor on which is mounted a small transverse conveyor. T he sheaf-contained in the receiver is set upon the transversely,moving conveyor and delivered to the longitudinally moving conveyor which is long enough to contain several sheaves. Atterthelongitudinally moving conveyor has been filled, it is carried to the rear end of the floor where the sheaves are deposited in a row. This operation'is re: peateduntil the entire floor of the machine is covered with a shock of sheaves.. V

At this instant an automatic apparatus is set into motion to lower thefloor, which is hinged and to transfer the shock to the ground. This mechanisin-includes suitable bars which bind the head of the shock so that the base thereof is spread by its engagement with the earth so that each sheaf assumes a conical position. 'l he autoniatic mechanism further operates to raise the floor to its non mal position after the shock has been removed therefrom.

Reference to these views will now be made by use of like characters which are employed to desi nate corresponding parts throughout.

The frame of the m chine comprises a pair of longitudinal spaced rails 1 joined at an intermediate part by a sleeve 2 and provided at the rear ends with stub shafts 3. Through the sleeve 2 is iassed an axle e (Figure 23) formed intermedially with a wbrm 5 and carrying gears 6 at both ends. The stub shafts 3 carry the rear ground wheels 7 as clearly shown in Figures 1, 5 and 15, while the frame is extended forwardly in the form of a tongue 3 (Figure 5) from which is sus pended an arm 9 to carry the single forward ground wheel 10.

A rather short post 11 is mounted on the forwardpart 3 for the support of a crown gear 12 having a pair of converged fingers 13 extending therefrom. Between this gear and the pinion 5 is suitably journaled a shaft ll carrying at one end a pinion 15 meshing with the worm and at the other end another pinion 16 meshing with the gear 12. Between the shaft 1 1- and the pinion 16 is interposed a clutch 17 operable by means of a link 18 which extends to a point Within convenient reach of the operator or to a movable part of the bin der.

Between the sleeve 2 and the gear 12 is provided a rod 19 having at one end a universal joining connection 20 with the frame. Between the members 2 and 19 is provided a curved track 21 engageable by a roller 22 carried by an intermediate portion of the shaft 19, the remaining end of the shaft carries a receiver 23 which is shown in greater detail in Figure 12. The receiver has a flat bottom 24 and a curved wall 25, while three iarallel slots 26 are out in the bottom for a purpose presently to be described. The point of intersection of the fingers 13 is joined by means of a link 27 to a collar 23 on the shaft 19. Adjacent the universal joint 20, a quadrant 29 is lined to the frame for engagement by a pinion 30 on the shaft 19. It will be evident that if the clutch 17 is closed while the machine is riding, rotary movement will be imparted to the gear 12 whereby the fingers 13 will swing the rod 19 and receiver 23 in an arcuate path along the track 21 first in one direction and then in the other.

In one of the rails 1, directly behind the sleeve 2, is journaled a stub shaft 31 carrying a series of straight horizontal lingers 32 and a gate comprising curved fingers 33. Vihen a sheaf of grain is thrown into the receiver and the latter swung in the manner already described, the contents of the receiver are prevented from falling out by means of a curved guard 34c'carried by the frame. When the receiver has reached its innermost limit it engages the lingers and swings the member 31 counterclockwise. The fingers 32 pass through the slots 26. Beneath the rail 1, the stub shaft 31 carries a pinion with the interposition of a clutch 36 as shown in Figure 29. Directly forward of the pinion 35, a bracket 37 is secured to the rail 1 and supports one end of a spindle 33 (Figure 2) extending half way across the frame and provided at its ends with bevel pinions 39 and 410 respectively. The latter is in engagement with. the pinion 35.

Directly behind the spindle 38, another shaft 41 is journaled in the parallel rails 1. Bevel pinions are mounted at the ends of the shaft 4* and are engaged by similar pinions 43 carriedby clutch elements lelsupported by a transverse bar 4 5. The movable elements of the clutches are connected to bell crank levers i6 pivoted to the bar 15 and further joined by a link 17 having a finger 13 projecting from its centre. A spindle 49 is n'iounted medially of the frame and carries at one end a bevel pinion 50 meshing with the member 39. The shaft also carries a series of four fingers 51 adapted to engage the finger 18. It will be seen in Figure 2 that the extremities of the shaft 41 are provided with pinions 52 which mesh with the gears 6 already mentioned. The ends of the shaft 1- are geared to the stub shafts 3 by sprocket chains 53 as clearly shown in Figure 1. Also, the clutches 1 1- are interconnected by a sprocket chain 54.

It will be evident that the gate 33 and consequently the stub shaft 31 are turned onequarter revolution each time the gate engaged by the receiver 23 in the manner already described. T his movement is imparted through the pinion 35 to the pinion 10, spindle 33 and shaft 49. The four fingers 51 on the shaft 49 therefore engage the fingers 48 periodically and thus shift the link M. In this manner one of the clutches is periodically geared to the shaft 41 whereby the chain 5 1 is operated.

The ends of the shaft 11 are geared to stub shafts (Figure 1) at the end of the frame by means of sprocket chains 56. Immediately rearward of the gate 33, a conveyor plate 5'? is mounted transversely of the vehicle and adapted to move longitudinally thereof. To the lower surface of this plate is secured a pair of brackets 53 (Figures 32, 33

and 34-) through which ispassed a rotatable shaft 59 having upturned ends 60.- Between the laps of the chains-56theshaft 59 carries a pair of double toothed members 61, and the upper lap of the chains isprotected by cover plates 62 suitably supported by thetraine oi the machine.

Between the rails 1 a floor 68is hinged-- ly mounted as indicated by the numeral 6% in Figiire 10. The floor is provided near its lateral edges with rails or tracks 64.

Arms 65 project from the rear edge of the conveyor 57 and carry rollers 66 receivable in the tracks 64. Another set of rollers 67 is carried by the conveyor 57 for guidance in the tracks as illustrated in dotted lincsin Figure 1. i

Upon the longitudinally moving conveyor 57 is mounted a transversely moving conveyor 68 having rollers 69 which ride in grooves 70 out in the member 5'7. To the bottom of the conve or 68 is hinged a lug 71 adapted to engage the chain 5st as shown in Figures 30 and 31, whereby thechain inoves "the conveyor transversely of the machine.

A series of gates 72, '73 and Mare hingedly mounted in a transverse wall 75 carried by the conveyor 57. The endgate 72, farthest removed from the gate 33, has a notch 76 (Figure 20) engageable by a dog77 mounted in the conveyor 57.. When the dog is received in the notch, the gate 72 is in the open position shown 1n Figures 1 and 19.

In the conveyor 68 is mounted a pair oi? rotatable studs 78 and 79 which are under the tension of springs 80 as shown in Figures 13 and 14. These springs act in the direction of the arrows placed beside the studs in Figure let. The stud 7 8 carries a series of curved gate bars 81 and a lug 82, while the stud 79 carries straight fingers 83 and a,

hook 84 adapted to receive the lug 82.

In the operation of thedevice thusitar the double clutches whereby the chain 54 moves and carries the conveyor 68 as far as the gate 72. As-the conveyor 68 approaches the gate 72, a projection 85 (Figure 20) passes over an abutment 86 on the. dog 77 and releases the latter from the notch 76. The gate is under tension by a spring 87 (Figures 19 and 22) and therefore binds the sheaf against the wall 75. Since the conveyor 68 can no longer move in the same direction,

the clutch at this end. opened: as, a; result i the C011i111111l11g TORI-i101 (of the pinlon 52.

opening movement of the clutchis transinittedthrough the bell crank'levers 46, and link 4J1, whereby the clutch at the starting end is closed and the direction of p j 57 rovers The conveyor 68now proceeds i n the reverse direction The link 47 and thebottoinof theconveyor 68 are provided withfriction blocks I 88 and 89 respectively which are positioned to engage one another when the conveyor-is instarting position, as illustrated in Figures 39 and (l: The engagement of these blocks brings the clutches to open position and holds them in that condition so that the conveyor 68 remains stationary until one of the clutches. is locked during the movement of the gate 38 as already described. 1

The conveyor 68 is providedwith aiinechanism of the type shown in Figures 25, 26 and .27. This mechanism comprises a stud 90- which carries twofingers 91 and three shorter lingers 92 spaced equidlstantly around the the chain stud. Thelatter inernber also carriesaratchet 93 limited to inoveinentin one direction by a pawl 94 pivotally attached to theoonveyou 68. To the conveyor 57 95 adjacent the gates 73 and 74 asshown in" Figiu'es23 and 24, for the purpose of engaging and the bottom of each gate 73 and 74 is secured a curved finger 96 which extendsintoa corresponding slot 97 out through the conveyor 57 as shown in Figure 26. It will be obvious that the shorter fingers 92 are not long enough to reach the end of the hunger .96.

After the v conveyor 68 has returned to starting position,

sheaf is depositedon the conveyor 68. I

end of the spindle 19 carries a linger adapted to engage another linger 101 projecting from the shat't 59. The gearing controlling the shaft 19 is so arranged that after four sheaves have been deposited and the stud 31 act-uatedfour times, the finger 100 will engage the member 101 to tilt the shaft 50 on its axis. The double teeth 51 carried by this shaft will thus be brought into engagement with the rearwardly moving lower lap of the chains 56, whereby the two conveyors 5'7 and 68 will be moved bodily to the rear ends of the rails It will be seen in Figure 5 that the rails 1 oi the machine are provided with several posts'arranged in pairs transversely oi the machine as indicated by the numerals 102, 103, 104: 101, 153 and a l'ixcd extension enclosing the rotatable stud 31. When the transverse conveyor 51' reaches its rearward limit, the upturned ends 00 or the shaft 50 engage a linger on each post 102 as clearly shown in Figure 3%. Due to this contact the shaft 59 is turned in its bearings whereby the teeth 01 carried thereby are brought into the forwardly inoving lap of the chains 50 so that the conveyor 57 is returned to its horizontal position. A plate 100 (Figure 3) having a COIIVGX upper surface is secured to the frame at each end at the shaft 59 and is en gaged by pins 10? carried by the double teeth 61 when the conveyor 57 reaches its torward limit. The curved plates 10G bring the teeth 61 into a neutral position to allow the conveyors to be filled in the manner already described.

The posts 103, 101 and 10 1 are rounded at the base whereto rotatably supported gates 103, 109 and are hinged as shown in Figure 15. The gates are comprised of two sets ct arms at right angles to each other. When the linger 105 on the post 103 is engaged by the upturned ends (50, the gates 101' are swung so that the one branch thereof: is brought parallel to the rail 1 while the other branch engages the forward side of the sheaves and prevents them from creeping forwardly. Obviously the preceding gates 109 and 110 are also turned by the moving row of sheaves, but are eventually caused to take the position described with reference to the gates 100.

A pair of curved bars 111 are hinged the posts 102 to prevent the rearward row of sheaves from falling oil the machine, The construction and operation of these bars is described in greater detail below.

The remaining posts 101 and 10 1 carry star wheels consisting oilingers 112 as shown in Figures 6 and 7. Each such wheel carries a ratchet 113 to prevent slipping. The shafts also carry a rotatable finger 11 1- adapted to lie in the path of the upturned ends 60. The longitudinally moving conveyor 57 carries an upwardly projecting dog 115 adapted to engage the fingers 112 but not the member 111. Each rearward stroke of the conveyor 5'? causes the star wheels to be swung to the extent of the space between two adjacent lingers thereof. The number of lingers associated with the devices 109 and 110 is such that when a given row of sheaves is delivered to the floor, the corresponding lingers 111 will lie directly in the path of the upturned ends 00 so that the corresponding gates, will be swung to engage the rear s do of the row of sheaves and the teeth 61 will be thrown into the lower lap 01 the chains movement.

With reference now to Figures 30 and 33, it will be seen that racks 110 are slidably mounted at the res r end of the Frame. Each edge of the lloor carries a pin 117 receivable and adapted to work in a groove 118 cut in the adjacent rack. Due'to this support the position of the lloor depends on the position of the racks.

Each side rail 1 contains a pin 119 adapted to enter a cavity 120 in the adjacent rack. The pin is normally pressed into the cavity by ineans'oit' a spring 1 1 bearing on a-collar 122 formed on the pin and on a screw cap 123 threaded into the side of the rail 1. The outer end of the pin is provided with a head 12 1.

As shown in Figure 21 the linal or forward post 101 carries still another linger 125 adapted to engage a bell crank lever 120 pivoted to the adjacent rail 1. The head 121 already described is engaged by another bell crank lever 12? pivoted adjacent thereto on the frame of the machine. The bell crank lever 12? is joined to the member 126 by means of a link 128. When the post 10s has been turned to engage the last row of sheaves on the li'oor the linger 125 swings the bell crank lever12l3 whereby the member 127 also swung to renio e the pin 119 from the cavity 120. The 1'... s 110 are thus permitted to drop, carrying with them the liner 03 which falls to the position shown in Fig ure 10. i

The intermediate part of the frame includes a pair of uprights 129 (Figure 5) between which is journaled a shaft 130 carrying a pair of sprocket wheels 131.- The upper ends 132 of the posts 102 serve to support pair of s ightl inclined bars 133. On these bars are mounted slidable bearings 13% rotatable with the bars and carrying pinions 135 which mesh with perpendicular pinions 136. The latter are mounted on slidable bearings 136 (Figure 16) from which extend stub shafts 136 carrying a pair of sprocket wheels 13'? in line with 17110 ll'lQHllJGlf-l 131.

The low r end of each rod 133 carries a bevel pinion 138 meshing with another pinion 139 carried by the stub shaft 55 which is driven by the chain 50 as shown in Figure 1. The shafts 133 are therefore constantly in motion during the travel of the machine,

for return buta'clutch (Figure 16) is provided adjacent each gear 136'.

The shafts 130 and 136 support a trough 1&1 on which isbuilt asuperstructure1 12 comprising tracks 143' which contain the chains connecting the sprockets 131 and 137. In the troughis received a pair of blocks lit-s; which are joined by a cross shaft 14f (Figure 17) passed therethrough. The shaft is fun ther joined tothe sprocket chains by links 146 as sl'iown in Figure 5. Y

It will be seen in Figure 16 that each of the clutches 14:0 coinprises a clutch face 1417 carriedby the pinion 186, a 'slidable face 148, having a canifaceand adjacent this a. bar 1 19 having cam edges 150 receivable between the member 148 and anothercam face 151 carried by the sprocket wheel 187. The spring 152 is placed between the gear136 and the arm 149'to normally hold the clutch open. V

To one of the fixed posts 150 of the frame (Figures 5 and is pivotally connected one end of an arm 154, the other end of which is connected by means of a. linl 155 to a bar 156 loosely mounted on the rear'axle. The free end of this bar is adapted to ork in a slot'157 out inftheodge of thefloor that the link 155 isac'tually connected to the floor. A rod 158 extends outwardly from the free end'of the bar 15 1 and is joined to the cross shaft 1 15. -This construction is provided at each side of the machine. Vhen the floor drops by the operation already described, the rods 158 and the cross shaft 145 are also lowered. 7

To each of the blocks 14% is pivoted a bell crai'ilrlever 159 having one end engageable by' a pin 160 on the bloclcl l. Each bell crank lever is connected by means of a-link 161to the corres 'ionding arln 14.9 already described in connection with Figure 16. It will be apparent that these linkages control. the clutches 1 10. Spring pressed means may beprovided for normally holding the bell crank levers 159 in such a position that the Clutches are held open. When the rods158 drop; the bell crank levers 159 are turned and the link 161 are pulled tobring the clutches into the closed position which is illustrated in igure 16. i I

The trough 1 11 and the lower lap the track 14-3 are formed with a-lined bearings 162 and 163 respectively as shown in Figure Stwherein is journaled a shaft 164: at each side of the machine. These shafts carry the curved arins 111 which have been previcusly mentioned. Fla-chisucharin hasahoss. 165

Atthc' sanictiine the sheaves are engaged by the cross shaft 1 15 as shown in Figure 17 and Y therebycarried off thefloor upon the ground.

" fllieheads of the sheavesare con'ipressed as 7 shewn in Fi ure' 17, and the frictional en- :gageinent of the lo'wer'ends of the sheaves 7 with the earth in passing off the floor-causes theshea-ves tobe spread at the'bottoin, as a result'oif which they reniainlstanding on the groundas previously described in detail.

To the inner side ofeach ofthe rails 1' is secured atrack 172 (Figures 35 to 38) v on 1 which slides a block 173. 'The'rear end of the block is formed with the slot enlargement 175; A square shaft 176'has a reduced end 177 receivable and movable in the slot and enlargement thereof, The rear edge of eachof the racks 116 iii) 178 slida'blv received in the adjacent block-173 whereby thefrackis niovahle with the block and at the same time slidably mounted in relatien theretoin the vertical direction. Near the toothed edge of each rack is mounted a pinion 179 which is either carried by the rear axle *of the machine as shown in Figure 1. er suitably driven thereby.

Each block 173 is cavity 180 into which e7 jecting from thetrack 172i is mounted a coil ,sp1'i11g 182 betweenthe in and the forward wall of the cavity, whereby the rack 116 isiiorinally pushed towards the pinion 179. The reduced end 177. of the square shaft 166,-however,

After the sheaves have been discharged from the floorof the machine, the lugs 18% engage the lingers 183 and turntl'ie square shafts 176 so thatthe reduced ends thereof are in line with the s 'ts 174i 7 free to move under the action of the springs 182. whereby the racks 116 are brought into is geinent with the pinion 179 as shown'in ure 1 S6.

As shown in Figure 38, the frame has a bell crank lever 1S6 pivoted thereto while the rack carries a cam 187. In the rising movement of the rack the two cams engage one another as in Figure 38, and the rack and block 173 are therefore moved rearwardly due to the spacing between the rack and pinion caused The lugs 18l return past the finger 183 at the instant that-the reduced shaft end 177 is again re ceived in the enlargement 175. I T he engagement between the lugs 18d and finger 183 turns the shaft to the position shown in Figure 35 whereby the block 173 is again locked in its rearward position. On return of the block to the position shown in Figure 5, the rearward clutches are again opened.

The bars 111 are in open position only during the movement of the pin 170 by the pin 171. After these pins have become disengaged the bars return to the sheaf so that the head of theshock on the floor 63 is constantly held between the bars and the cross shaft to permit the formation of a conical bundle standing on the ground as already described. Naturally, the bars 111 give way under the pressure of the cross shaft 1&5 in order to permit transfer of the sheaves to the ground. The pawl and ratchet mechanism illustrated in Figure is applied to the rear stub shafts 3. The ratchet 188 is associated with the adjacent pinion 17 9 and sprocket chain through the shaft 3. The pawl 189 is carried by an outer shaft 3" which turns with the ground wheels. When the vehicle is moving forward, the pawl turns the ratchet and operates the mechanism described. If the machine is backed up the pawl merely slips over the ratchet so that the parts associated with the latter remain operative.

lVhile a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.
