GRAIN-STOOKERE Specification of Letters Patent. Patented Sgpt; 25, 1917;

Application filed June 2, 1916. Serial No. 101,424.

To all whom iii-may concern:

Be it known that I, \VILLIAM HAGKLY CHURCH, a subject of the King OfGrIGEIt Britain, and resident of Superb,in the Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Grain-Stookers, of whiclr the following is the specification.

This invention relates to improvements in grainstookers and the objects of the invention are to facilitatein forming the sheaves of grain into a stook and readily discharge the same, to permit of the heads of the sheaves being readily bunched together dare ing the operation of dumpingthe stooks, to readily pack 1 the sheaves in position, and other objects to be made clearhereafter,and it consists essentially of the improved construction particularly described and set forth in the following specification and accom-.

panying drawings forming-part of the same.

In the drawings,

Figure 1 is an end elevation of the improved machine.

Fig.2 is a plan view of the same: i v

Fig. 3 is a side view of the machine showing the location of the packing arms and the means for operating the same.

Fig. i is an enlarged perspective view, partly in section, of the packing arms and showing the means for preventing the sheaves being delivered to the basket collector when the stook isbeing clumped.-

Fig. 6 is a longitudinalsection of the spring controlled drum controlling the actionof the upper portion of the basket collector.

Fig. 7 is a fragmentary elevation, part being in section, of the cam member and its 'coactingroller controlling the closing of the upper portion of the basketcollector.

Fig. 8 is a perspectlve View of a chain tightener adapted to coact with the zmain drive of the machine.

Fig/9 is a fragmentary perspective view. of the mechanism controlling the rotary 1110- tion of the basket collector.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents frame E rotatably supporting the inner end thereon, the inner' end of which is SUbSlZflll i tially curvilinear as shown at 17 and adaptedto engage with the pin 18 thereby limiting=the outward motion of the said lever whichis adapted to be pressed inwardly to engage :with the spokes of the wheel 1 1- in a manner to be made clear hereafter.

Rotary motion is transmitted to the shaft 11 by the disk 10 provided with the curvilinear slot 19 having a plurality of notcl ies 20 therein adapted to engage with the offset end of the lever 21, the other end ofwhich is engaged with one ofthe orifices 22 provided in the crank arm 23 of the spindle ii, the opposite end of which isprovided with a crankarm 25 angularlymlisposed to the crank arm 23 and carrying a cam member 26 adjustably mounted. thereon.

The lever 16 is provided with a projection 27 designedto be engagedby the spring adapted to hold the said lever normally disengaged, from the spokes of the wheel. 14-, the said lever being adapted to be moved into engagement with i the said spokes through the medium of the bell crank 29 bracket 34 and is provided with a sprin 35 located between thebell crank 29 and the said bracket.

During the forward motion of the wheel 14 rotary motion is transmitted to the shaft 11, which through the medium of the chain 36 operatively connecting the sprockets 37 and 37 rotates the shaft 38 which carries a. beveled pinion 39 meshing with the beveled pinion 40 mounted on the transversely extending shaft 41 so transmitting rotating motion thereto.

This shaft 41 is rotatably mounted in the bearings 42 carried by the frame E and is provided intermediate of its length with sprockets 43 operatively connected by the chains 44 to the sprockets 45 carried by the shaft 46 rotatably mounted in one of the arms of the inverted Y-shaped end brackets 48 of'the frame G, the said shaft being provided intermediate of its length with crank members 49 on which the packing arms 50 are pivotally mounted.

' The forward ends of the packing arms 50 are substantially V-shaped while the rear end is pivotally connected to the lower end of the links 51, the upper ends of which are pivotally connected to a U-shapedbracket 52 carried by the frame E.

The upper ends of the inverted Y-shaped brackets 48 are pivotally mounted on the shaft 41 and are operatively connected by an inverted U-shaped rod 53 forming part of the frame G, while the third arm of the said brackets is connected by a transversely eX- tending rod 54 carrying a spring 54 adapted to hold the frame G in a normal retracted position. The outer end of the crank shaft 46 makes engagement with the lower offset end 55 of the lever 56 which is pivotally mounted to the frame E and provided with an offset arm 57 adapted to engage with the angular stop member 58 rigidly mounted on the lower portion 13 of the basket collector F.

The Y-shaped brackets 48 are also operatively connected by flexible members 59 with the bar 60 which is provided intermediate of its length with upwardly extending arms 61 slidably mounted in the inverted V-shaped frame 62, the inner face of which is adapted to guide the sheaves into the basket collector F, the flexible members 59 being designed to engage intermediate of their length with the guide pulleys 63 suitably secured to the frame E.

The upper portion 64 of the basket collector F is hinged to the lower portion 13, the motion of the upper portion being controlled by the curvilinear arms 65 rigidly secured to the curvilinear portion 12 of the shaft 11'. This upper portion 64 carries a pair of brackets 67 rigidly attached thereto and operatively supports the drum 66, the rotation of which is controlled by the spiral spring 68 wound around the pin 69 having one end rigidly attached to one of the brackets 67 and the other end extending through the periphery of the said drum.

The drum is also provided with a pair of projections 70 to which the ends of the flexible members 71 are connected, the said flexible members engaging with guide pul- Located adjacent to the curvilinear arm 65 is a resilient packing member 74 .formed in a substantially U-shaped portion which projects into the basket collector F, the free ends of the said member being rigidly connected to the upper portion 64 of the basket collector. The upper portion 64 of the basket collector is further provided with a bracket 75 carrying a roller 76 on the upper end thereof adapted to coactwith the cam portion 26 which is provided with a curvilinear slot 77 with which the-adjusting bolt 78 carried by the crank arm 25 is adapted to engage.

Coacting with the lever 16 is a frame 7 9 which is almost completely circular, being provided however with a gap portion which permits of the said lever beingfreed from engagement with the spokes, the said frame being adapted to engage with the lever 16 and holdthe same in engagement with the spokes until the wheel 14 has rotated through one revolution when the offset end 80 of the frame allows the lever to be released and returned under the action of the spring 28 to its normally disengaged position;

During the period when the lever 16 is in engagement with the wheel 14, rotary motion is transmitted to the shaft 11, the inner end of which is provided with a cam member 81 designed to engage with the roller 82 carried by the offset arm 83 mounted on the U-shaped rod 53 which rod is, due to the displacement of the offset lever 56, thrown inwardly permitting the engagement of the roller 82 and cam 81 to take place.

Simultaneously with this rotation, it is desirable that the sheavesshould not be fed to the basket collector'F, and to this end a lever 84 is pivotally-mounted on an angle bracket 85 carried by the frame G, the inner end of the lever being bifurcated to embrace the U-shaped rod 53, the outer end being provided with a pinion 86 adapted to mesh with the pinion 87 carried by the shaft 41 and the pinion 88 carried 'bythe conveyer roller 89 thereby resulting in the conveyer H being rendered inoperative.

This conveyer may be of any usual construction and is carried by the frame 90 Pivotally mounted to the HD1 T0116! lower end of the links 92, theupper ends of which are pivotally connected to the brackets 93 carried by the frame E, the adjustment of this frame I being controlled by a lever 94 pivotally mounted intermediate of its length to oneof the brackets 93 and pivotallv connected at its lower end to the said frame, the lever being providedwith a detent 95 coacting with the quadrant 96 rigidly. mounted on the bracket 93.

marinas The adjustable frame I is pivotally con nected to one endof the link 0 which is attached to the binder frame, audit will readily beseen that bv utilizing a pivotal attachment of this nature thebinder may be raised or lowered to suit the length of grain being out, while the said frame mav be adjusted to correspond with the elevation of the binder.

Simultaneously with the rotation of the basketcollector F the door J which closes the end of the said basketis designed to be withdrawn from contact therewith under the action of gravity, andtothis end the door is attached to the frame 97 hung from the frame E. r i i The door is normally held in closed position by the roller 98 carried by the crank arm 99 of thespindle 100, the other end of which is provided with a crank arm 101 having a plura' lity of orifices therethrough with which one end of the link 102 engages, the'other end of the link being adjustably connected to the lever 21 whichis operatively connected to the spring 103 anchored to the frame E. V i

The assembly of the machine will be readily understood from the foregoing description. i i When the machine is in use the sheaves are delivered from the binder deck I) and delivered to the frame E where they are engaged by the conveyer H and delivered to the basket collector F, the upper portionv 6d of which is normally held in an open position as will be seen by reference to Fig. 1.

i In the forwardmotion of the machine it will be understood that the sprocket wheel 37 which is rigidly attached to thewheel l-i is rotated thereby and rotary motion is tral'ismitted through the chain drive 36 to the shaft 38 which in turn i rotates the shaft ll causing the packing arms 50 to be reciprocated through the bottom portion 13 of the basket collector so that as the sheaves are delivered to the basket collector F they are tightly packed in position by means of the said arms. hen the desired number of sheaves have been delivered to the basket collector F the driver exerts a pull on the flexible member 32 thereby rotating the bell crank 31 and causing the bell crank 29 to throw the angle lever 16 into engagement with the spokes of the wheel 14 so that during the rotation of the wheel 14 the shaft 11 will be rotated in a forward direction dumping the sheaves in the basket collector on the ground in the form of a stock.

Duriin the rotation of the shaft 11 it will be understood that the lever 21 through the medium of the link 102 actuates the spindle 100 and disengages the roller 98 from the door J permitting the same under the action of gravity to become disengaged.

from the lower end of the basket collectm! l5" and at the same time the lever Ll. also actuates the spindle 2i causing the cam member26 to engage with the roller 00 and so close the upper portion (it on the lower portion 13 of the basketcollector.

During. the period of dumping, the resilient ll-shaped member 74 engages with the heads of the sheaves, bimching the same together while the stook is beingdeposited on the ground so that the base of the stock will be extended and the heads will lie close together.

When the basket collector being thus located the angle slop memberS engages with the upper offset arm 5? of the lever 50, the lower end of which moves or swings the frame G aboutthe shaft 11 so that as the lower end of the frame moves outwardly, the rod carried by theupper end of the frame moves inwardly toward the inverted vi-shaped frame This movement of the rod 53, due to its engagement with the bifurcated end of the lever 8 1, moves or retates the said lever which is fulcrumcdintel-mediate of its length to the bracketSfi so thatas the longer arm of the lever is moved toward the inverted V-shaped frame 62 the shorter arm is moved. outwardly and disengages the pinion from the piniens 87 and 88 so rendering the conveyer H inoperative.

Simultaneously with the throwing of the pinion 86 out of gear the bar 60 is operated due to the motion of the frame G, and re sults in the elevating oft-he arms ()1 which project above the frame 62 and prevent any sheaves from being inadvertently delivered to the basket collector F. During the ref tion of the basket collector F the frame (lis held in this displaced position by the cam 81 which engages with the roller-82 carried by the arm attached to the ll-shaped bar .53 forming a portion of the said frame and after the basket has completed one single revolution the roller 82 becomes disengaged from the cam 81 permitting the frame G to return to its normal position in which the lever Se is actuated and the pinion 86 thrown into gear with the pinions 87 and 88 resulting in the operation of the conveyor H which delivers the sheaves to the basket collector F.

The shaft fl is rotated from the main drive of the machine as already described and the packing arms 50 tightly pack the sheaves in position in the basket collector which when a sufficient number of sheaves have been delivered thereto, is again dumped in the manner already described.
