T all whom it may concern:

Be it known that I, HARRY G. Hanson, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, 816 Hague avenue, have invented certain new and useful Improvements in Shocking-Machines, of which the following is a specification.

This invention relates to improvements in shocking machines, and has for its object to provide a practical device for depositing sheaves of grain in the form of shocks from the discharge table of a binder, upon the ground.

A further object is to provide a device whereby the sheaves maybe slid from the discharge end of a conveyor by gravity to the shock-forming mechanism, to be deposited therefrom on the ground.

A still further object is to provide device which may be attached to the 'frame supporting the bull-wheel and to the evener bar of a binder and which may be of light sheet metal construction, having its moving parts driven by the movement of its supporting wheels.

In the drawings,

Fig. 13 is a fragment of the reciprocating chute gate leadingto the shock-forming receptaclc,

Fig. 11 is a perspective view of a detail,

Fig. 15 is a fragmentary perspective view of the axle.

Referring to the drawings, A is the frame receiving platform B connected with an elevator conveyer C, said conveyer and plat form having vertical and horizontal adjust-- ment on said frame.

Adj a-cent to the discharge end of the conveyer and pivotally mounted on the frame is the tilting cradle D.

Mounted on the rear end of the frame behind the wheels 2 is a shock-former E, comprising a pair of comparatively long rectangular receptacles F and G arrangedside bv side lengthwise, each having a pairof upright doors 1 and a pair of hinged "bottom doors 5, and being provided longitudinally with a wedge shaped divider 6 central of its width and at the bottom thereof, and an -adjustable separating plate 7, also central widthwise of said receptacleand approximately flush with the top thereof in its uppermost position. 7

Between the shock-former E and the tilting cradle D and operatively connected with both is the gravity chute H comprising .a receiving end S communicating with a pair of tributary chutes 9. and 10 which in turn communicate with the receptacle F midi respectively.

Journaled in the. frame at the point of convergence of the tributaries 9 and 1.0 and projecting downwardly is the, spindle 11 having rigidly mountedthereon agate 12-, which is adapted to reciprocate late-rally from the outer wall of the chute .9 to the outer. wall ofthe chute 10 so .as to form in either position a continuous passageway with the receiving end 8.

The gate valve 12 is rcciprocated by meafns of plurality of arms 13 mounted in a hub .14 (to form a spider) which has threaded bean ing on the threaded stem 15 which latter carries the gate 12. p

The hub 14 is provided at its top and bot tom with an upwardly and downwardlyprojecting lug 16 and 17 respectively. The stem 15 has adjustably mounted at its top a collar 18 having a downwardlyprojecting lug 19 whereby, when said arms 13 are caused to turn until the lug 16 engages the lug 19, the stem 15 will be turned, therebylmoving the valve12 into contact with the outer wall of the chute 10.

When however the movement of the arms 13 reversed the lug 17 will engage the upper edge of the gate 12 and move it laterally against the outer wall of the chute 9. Thus, as the sheaves pass through the receiving end 8 and contact with the arms 13, the spider is caused to turn as each succeeding sheaf slides through the chute until the hub 1 f will have reached its upper or lower limit on the threaded stem when it will. move the gate valve 12 in its respective direction as above described.

The lower end of the stem 15 is journaled in a bracket 20 secured on the bottom of the chute and is adapted to frictionally engage said stem by means of separated ears 21.

clamped together by a bolt.

Rotatably mounted on the frame A and at the receiving end of receptacles F and G and below the bottom thereof and rotatable in a horizontal plane is the tripping disk 22 wherein is vertically journaled the rod 23 which carries rigidly at its upper end the gate 24 having a pair of .rearwardly and outwardly extending wiping arms 25.

The frame A holding journaled in the opening 26 the tripping disk 22, is provided with a friction block 2'? having set-screw adjustment whereby the tripping disk may be frictionally engaged so as to prevent said disk from spinning in its hearing. The tripping disk comprises a flange 23 having four equidistant peripheral notches 29 adapted to receive, to loosely pass through it, the antifriction roller 30.

The anti-friction roller 30 is journaled (to roll in a vertical plane) at the upper end of the lever 31, which is pivoted at its lower end in a crank arm 32 mounted rigidly on the cross shaft 33 which is journaled by means of journal blocks 3% on the bottom of the shock-former receptacles.

Rigidly mounted on the cross shaft 33 are the beveled gears 35 which mesh with the beveled gears 36 which in turn aremounted on the shaft 37 journaled in blocks 38 secured on the upright side walls of the shock former receptacles.

On the rear end of the shaft 37 is mounted the beveled gear 39 which meshes with the beveled gear LO, said beveled gear 40 being rigidly mounted on the upwardly projecting shaft ll, upon which is rigidly fastened the door 4:.

Thus when the cross shaft 33 is caused to be rotated the doors 5 rigidly hung on the shaft 37 and the doors 4 rigidly hung on the shaft l-l will be caused to swing outwardly and downwardly respectively as shown in dotted lines in Fig. 1.

A counter-balancing weight 51-2 adj ustably held on. the lever 43 which is adjustably fastened on the cross shaft 33 is adapted to counter-balance the doors as the shaft 33 is turned, so as to cause the .,.doors 5 to swing slightly beyond the plumb position out wardly and also the doors 4 to an outward position as shown in Fig. 1, so as to provide suflicient clearance for the sheaves, which will be hereinafter explained.

The tripping disk 22 is'formed above the flange 28 with an annular cup-like portion 44, the bottom of which is formed with teeth 45 forming an internal ratchet gear. The rod 23 is formed with a crank arm 4L6 having a downwardly projecting pin 47, which is adapted to slidingly fit in the slot 4-8 of the loose spring-pressed pawl 4E9, said pawl engaging the teeth 45 so that when the rod 23 is intermittently rotated in its bearing, the pin 47 will alternately engage the ends of the slot a8 to actuate the pawl shuttlewise to turn the disk 22 the distance corresponding to the length of one of the teeth 45, the slot 4L8 providing sufficient lost motion for the pin L7 to effect a movement of suitable circumferential length to effect a quarter turn of the disk 22 in eight movements of the crank arm 46 for the purpose hereinafter to be described. The spring 50 tends constantly to keep the pawl, 49 in constant engagement with the teeth -il-5.

The rod 23 is inclosed by the vertical tube 51 which carries adjustably at its top the separating plate 7 which may be lowered on the tube 51 when the sheaves are composed of short grain. The gate 24: is journaled at its lower edge on the tube 51.

Pivotally connected with the lower end of the crank arm 32 and projecting forwardly and upwardly and having pivotal connection 52 with the toothed plate 53, which latter slidingly fits in the housing 5% so that it may slide in a horizontal plane in line with the travel of the machine, is the lever 55.

The teeth on plate mesh with the gear 56 which has threaded engagement with the shaft 3, said thread being left-handed, so that when the supporting wheels 2 rotate in the direction of travel indicated by the arrow (Fig. 2) the gear 56 will not engage the toothed plate, but is adapted to engage the teeth thereon only when it is moved forward.

The shoulder 57 on the shaft 3 is provided with a pair of laterally extending lugs 58 which are adapted to engage the lugs 59 on the adjacent face of the gear 56 so that when the gear 56 is fed on the screw-thread of the shaft 3 toward said shoulder, the ll'igs 59 and 58 will contact and prevent the gear 56 from wedging fast on the thread.

As the sheaves descend on the gravity chute and engage the wiping arms 25 to operate the gate 2-1, an intermittent movement is transmitted to the tripping disk 22 by means of the pawl 49, the gate 24L reciprocating from one side of the chute to the other, alternately admitting asheaf of grain into each half of the shock-forming receptacle F or G as the case may be.

When four complete reciprocations ofthe gate 24 have been completed, a notch 29 will have moved into alinement with the antifriction roller 30, on the upper end of the lever 31, said roller through the influence of the counter-weight 42 then moving upwardly through said notch 29 and assuming the po-- sition indicated in dotted lines in Fig. 2, the lever 25 thrusting the toothed plate 53 forwardly in its grooves in the housing 54, thereby engaging with its teeth the gear 56 and causing it to be fed (through the medium of a threaded engagement with the shaft 3) laterally across the plate 58,. the shaft 33 causing the gears 35, and 36, 39 and 40, to swing the doors 4 and 5 into discharging position.

The machine continuing to advance will draw the divider 6 and the separating plate 7 lengthwise out of the formed shock of sheaves, (best illustrated in Fig. 4) immediately whereafter the gear 56 Wlll again have reached its original position (shown in Fig. 9) the lugs 59 and 58 being now in engage ment, the further progress of the machine causing the gear to slide thetoothed plate 53 backwardly, thereby causing the counterweight 42 and all the intermediate mechanism to be actuated so as to move all of the doors to their normal receiving position.

The tripping plate 22 is formed with four cam faces60, (one for each of the notches 29) whereon the end of the anti-friction roller 30 is adapted to slide, the offset 61 between the bottom of the notches and the uncurved portion of the cam face 60 holding the antifriction roller against upwarc movement just after the counte1 weigl1t and the intermediate mechanism has been returned to normal position.

The outer end of the anti-friction roller 30 will travel along the curved portion of the cam face 60, the shoulder 62 guiding it and holding it against premature upward movement through the notch 29 until it shall have arrived at a position central with said notch. I

The cam face 63 prevents the roller 30 from entering the offset61, the roller being held in engagement with the cam face 60 by means of the spring 64. Thus the shockformer is automatically returned from discharging position to receiving position.

Further the moment of actuation of themechanism to discharge the formed shock is determined by the number of sheaves that have passed through the gate, said number being capable of change by inserting differently notched tripping disks, as for example, a disk having six notches. I

Rigidly mounted on the shaft 3 is a sprocket 65 meshing with a chain 66 which in turn meshes with a sprocket 67 mounted on a horizontal shaft 68 whereon is rigidly mounted a beveled gear 69 meshingwith a beveled gear 7 0, said beveled gear 70 being mounted on a vertical shaft carrying at its upper end a beveled gear 71 disposed at right angles to a beveled gear 72, which in turn drives the sprocket 73 meshing into the chain 74. The chain 74 is provided with the usual lateral spiked cleats which engage the sheaves to prevent them from dislodging in the operation of the conveyer.

Sprockets 75 at the lower terminal of the. conveyer also meshing with chain 74 are rigidly mounted on the shaft 76 which is journaled in the brackets 77. Brackets 78 corresponding in form to the upper portion of brackets 77 carry slidably the receiving platform B on the frame A. In the frame A is provided a series of holes 7 8* whereby, when said receiving platform is slid forwardly on the frame, the angularity of the conveyer may be changed, bolts then being inserted in the holes at the desired position.

Cooperating with the sliding movement of the receiving platform, uprights 80, provided with a series of bolt holes, move in unison with the bracket 77 so that the conveyer may be held in fixed position by means of bolts 81.

The platform B has a curved bottom 82, the receiving end of the platform being in alinement with the edge of the sheaf delivering binder table (not shown) and makes a quarter turn to its delivery end' which is parallel with the shaft 76 of the conveyer, a liberal descent being provided for, in the quarter turn so that the sheaves as they fall from the binder table make a quarter turn, the head or grain end of the sheaves centering in the zone immediate adjacent the center of the are described by the platform.

Adjacent the top of the conveyer and a suitable distance below the same is the tilting cradle D, having pivotal support on the shaft 83 which carries rigidly between the pivots a lever arm 84 on which is adjustably mounted a counter-weight 85. The shaft 83 is rigidly secured in the lugs 86 of the cradle so that the weight will tend to counter-balance the lower end of the cradle and will return the cradle to normal position as indicated in Fig. 1.

Referring to Fig. 7 of the drawings, the receiving end 8 of the chute is increased in width at its upper end so that the cradle re volving about its aXis 83 will have the upper edge of its-bottom S7 in close proximity to the outer wall 88 ofr-the receiving end of the chute.

The bottom of the cradle is inclined upwardly and forwardly so that when in tilted position the sheaf will fall forward as indi-' cated in Fig.7 and slide into the receiving end 8 of the chute, the cradle immediately (through the medium of the counter-weight 85) returning to receive the next sheaf from the conveyor. The sheaves are ordinarily sufficiently separated to permit the spider arms 18 free movement as the sheaves successively engage it.

A stop 89 on the chute serves to limit the rotary tilting movement of the cradle. Sheaves as they leave the binder ordinarily present a broad base of which applicant has taken advantage and which it has been found, will readily slide endwise on a smooth metallic surface, it being intended that the floor and sides of the chute H present a smooth or polished surface to facilitate the conveyance of the sheaves into the shockformer.

The relative distance between the collar 18 and the hub 14; when the lug 17 is in engagement with the gate 12 is such as to ad mit eight sheaves into one of the two tributary chutes 9 and 10 before the lug 16 and 19 engage each other.

The eighth sheaf will cause the spider to close the gate behind it, thereby directing the following sheaves into its tributary chute until the eighth sheave in that chute again actuates the gate 12 to repeat the action as before.

In the drawings, Fig. 1, I have shown two sheaves having passed the spider, which is merely to illustrate the position assumed as they slide down the chutes, but which can never occur since there are already four sheaves (as shown) in that side of the shock-former receptacle. Thus it will be seen that the spider divides the oncoming sheaves into groups of eight, alternately directing them into one or the other of the chutes 9 and 10, the groups being thereafter again divided alternately (one at a time) into groups of four on either side of the separating plate 7.

lVhen one of the shock-forming receptacles is filled with eight sheaves, the gate 12 is closed and the oncoming sheaves are being directed into the next adjoining shock-forming receptacle, the machine in the meanwhile advancing over the ground, during which period the formed shock is automatically discharged on the ground. This operation continues as the machine advances, one side of the machine discharging, while the other side is loading and forming.

At a point forward of the conveyer, the frame A is formed with a lateral extension 90 having a bar 91 parallel with the main frame and provided with connecting bolts 92 said bar 91 bein connected to the main frame with a pull rod 93.

Thus by means of the bolts 92, the shocking machine may be attached to the usual frame surrounding the bull-wheel of an ordinary binder, but which may of course be modified to accommodate machines of various patterns.

Opposite the extension 90 and at the forward corner of the frame A is the evener chain 94:, which is adapted to be hitched to a suitable evener bar and which may by means of a turn-buckle (not shown) be adjusted to swing the machine in alinement when necessary.

lVhile I have shown my invention with provisions for hitching to a binder, it is to be understood that the machine may be drawn by horses with suitable attachment therefor.

It is to be noted that the doors at lean slightly forward of the perpendicular, so that as the shock is deposited on the ground, the rear sheaves will be deposited in a forwardly leaning position.

Further, the floor of the chute and the shock-former from the receiving end S to the rearmost part of the machine is inclined rearwardly more or less throughout its length so that during the progress of the machine there is a constant tendency of the bundles sliding rearwardly and packing against the doors 4:, which insures the forward two sheaves in the filled shock-form ing receptacle to lean rearwardly, owing to the large base of each individual sheaf.

Thus when the shock is deposited on the ground the rearmost and foremost sheaves are inclined toward each other and more or less packed at their tops.

Referring to Fig. 15, the wheels 2 are rigidly mounted in the side bars of the frame A and held against end movement by set-screwed collars 95.

I claim:

In a shocking machine of the class described, in combination with a. binder and moving therewith, of means actuated by the supporting axle of the shocking machine when it is moved for elevating the grain. a slide including sheaf receiving and sheaf discharging devices for sliding the sheaves from said elevating means, and normally in receiving position, means for automatically actuating said discharging devices to discharge the grain, and means actuated by the movement of the shocking machine for restoring said discharging devices to receiving position, said means comprising a gear rotatably threaded on said supporting axle, and mechanism driven thereby when said gear is moved laterally a predetermined distance by said thread.

In testimony whereof I aflix my signature in presence of two witnesses.
