GEORGE A. DURANT, OF SASKATOON, SASKATCHEWAN, CANADA.

GrRAIN-SHOGKER.

Application filed June 8, 1917.

To all whom it may concern:

Be it known that I, GEORGE ARTHUR DUBANT, a subject of the King of Great Britain, residing at Saskatoon, Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Graiirshockers; and I do hereby declare the following to be a full, clear, and. exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device for shocking sheaves of grain, such as wheat, oats or the like, during the harvesting of the grain, and the primary object of the'invention is to provide a machine which will receive the bundles or sheaves of grain from the deck of a self binding harvester, and retain the bundles or sheaves until the desired number is accumulated, after which the machine will be operated for depositing the sheaves in shock formation upon the field.

Another object of this invention is to provide means for conveying the bundles or sheaves of grain from a binder deck to a retaining shock forming pan which means comprises a circular track, a plurality of cars which move over said track, and means controlled by the discharge of a bundle or sheaf from a binder deck into one of the receptacles for controlling the movement of said cars from a receiving position in close proximity to the binder deck to a delivery position above the shock forming pan.

Another object of this invention is to provide a track as specified which has a portion thereof broken away, so that when the car carrying the sheaf is positioned over the shock forming pan, the space will permit 4 the bottom of the car or hopper to move open to drop the sheaf or bundle of grain into i the shock forming pan.

A further object of this invention is to provide sheaf receiving and carrylng cars or hoppers as specified, the bottoms of which are hingedly connected to the car bodies and held in closed position by means of rollers carried by the under surfaces of the hinged bottoms which rollers ride upon the track structure, so that when the rollers move off the track structure, the hinged bottoms will move under the weight of the sheaves into an open depositing position, and further to hingedly connect the bottoms of the hoppers oppositely so that the sheaves deposited by Specification of Letters Patent.

Serial No. 173,582.

one of the hoppers willbe placed upon one side of a divider carriedby the sheaf pan while the sheaf deposited. by the other or opposed hopper. will be deposited upon the opposi e side of the divider carried centrally by the shock forming pan.

lVith the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved grain shocker having parts thereof broken away;

This invention isintended more particularly as an improvement upon the sheaf collooting and shock forming means disclosed in my United States Patent No. 1,204,139, dated Nov. 7, 1916. The various mechanisms employed in the present invention for securing the shock forming pan in adjustment and for compressing the shock and holding it in this pan during movement of the pan from a horizontal into a vert1cal position are similar to the mechanisms employed for this purpose in the machine d1sclosed in my patent above-identified and need not, therefore, be fully described in detail in this present case.

Referring more particularly to the drawings, 1 designates the deck of an ordinary grain binder and 2 designates the binder trip finger. When a sheaf or bundle of grain is discharged by the mechanism of the grain binder, it falls into the car or hopper 3, or into the hopper 4 depending upon which of these members is positioned for receiving the sheaf from the binder deck. 3

The hoppers 3 and i are attached to the outer ends of a pair of bars 5 and 6, which bars are in turn attached to a circular memher 7 as clearly shown in Fig. 5 of the drawings. The circular member 7 is provided with a pair of spokes 8 which extend outwardly from the hub 9 of the ring 7 as clearly shown in Fig. 5 of the drawings. The circular member or ring 7 is rotatably mounted upon a shank 10 which is formed upon a circular plate 11 centrally thereof. The circular plate 11 is supported by a plurality of supporting rods or braces 12 which braces are attached to and extend upwardly from the main supporting structure 13 of the shock former. The main supporting structure 13 is attached in any suitable manner as shown at l-l to the supporting structure of an ordinary self-binding harvester, and it has a supporting wheel 15 mounted upon its outer most end.

The plate 11 has a plurality of rollers 16 carried thereby at spaced intervals, which rollers engage the under surface of the rim 17 of the circular member 7, which rim is positioned below the plane of the spokes 8 as clearly shown in Fig. 2 of the drawings.

A suitable pin 18 extends transversely through the outer end of the shank 10 for preventing movement of the hub 9 longitudinally of the shank 10.

The shank 10 has a combined beveled gear and ratchet 19 mounted thereon, which member has peripheral ratchet teeth 20 formed about its periphery and beveled gear teeth 21 formed upon its under tapered portion. A beveled pinion 22 meshes with the beveled teeth 21 and continuously rotates the member 19 during the travel of the machine, and also during the operation of the grain binder to which the machine is attached. The beveled pinion 22 is mounted upon a shaft 23 which shaft is connected through the medium of a universal joint 24. to a substantially vertically extending chain travels. The sprocket chain 30 may also travel about a sprocket car 'ied by one of the rotatable parts of the grain.

binder.

The bottoms 31 and'32 of the hoppers 3 and at respectively, are hingedly connected to the hoppers, as shown at The bottom 31 is connected to the lower edge of the outer side of the hopper 3, while the bottom is hingedly connected at the lower edge of the inner side of the hopper 1, as clearly shown in Fig. 2 of the drawings, the purpose of which will be hereinafter more fully described. The hinged doors 31 and 32 have rollers 3st rotatably carried by their under surfaces. The rollers 31 engage a track 35 which is supported by the braces .12 and by auxiliary braces 36. When the rollers 3% are in engagement with the track the bottoms d 31 and 32 of the hoppers will be held in closed position for retaining sheaves therein.

The spokes 8 of the circular member 7 have pawls 39 pivot-ally carried thereby the action of which pawls are controlled by springs 40. The pawls 39 are forced by the springs so into engagement with the peripheral ratchet teeth 20 for rotating the circular member 7 by the rotation of the member 19. The circular plate 1.1 has a pair of trip members 40 carried thereby which engage the pawls 39 and hold them cut/ ef engagement with the ratchet teeth 20, allow ing the member 1.9 to rotate independently of rotation of the circular member 7, the e trip members being normally held in raised or operative position by leaf spring er secured to plate 11 and extending beneath the member 10, or in any other suitable manner. A flexible member, such as a rope or cable 41 is connected to the trip members 40 and it extends downwardly over a pulley 412 and is connected to an arm 43. The arm 13 is connected to the trip finger 2 of the binder mechanism so that when the trip finger 2 is operated by a bundle passing off the deck, the flexible member 11 will be operated for moving the trip members 40 out of engagement with the pawls 39. hen the members 40 are moved out of engagement with the pawls 39 the springs 10 will force the pawls into engagement with the peripheral ratchet teeth 20 and cause the disk? to be ro tated by means of member 19. The rotation of the circular member 7 will move the bars 5 and 6 and consequently move the hoppers 3 and 4: about the shank 10 as an axis, for moving the hopper which has just received the sheaves from the binder deck into a the charging position. The upper portion of the track 35 is cut away as clearly shown in Fig. 6, and the hoppers 3 and 4 move in the direction indicated by the arrow A in Fig. 6 of the drawings, so that when the hoppers reach the top or highest part of their movement, the rollers 34 will have moved off of the end 45 of the track, which will release the support for the hinged bottom of the hopper, and allow the sheaf to fall into the shock forming pan 46. The shock forming pan 46 has a centrally dis posed divider 47 carried thereby, which is provided for distributing or dividing the sheaves equally upon each side of the shock forming device. The bottom of the hopper 3 is hingedly connected to the lower edge of the outer wall of the hopper as previously described, so that when the rollers 34 carried thereby moves off of the track 35, the sheaf or bundle carried by this hopper willbe deposited upon the near side of the divider 47 and when the hopper 4 moves oif the end 45 of the track 35, the sheaf orbundle will be deposited from this hopper'npon the far side of the divider 47, owing to the fact that the bottom 32 will move into the position as shown in Fig. 2 of the drawings and guide the sheaf outwardlyover the divider.

The end 46 of the track 35 is curved downwardly as clearly shown in Fig. 1 of the drawings, for receiving. the rollers 34 carried by the hinged bottoms of the hoppers and guiding them upwardly upon the track 35 for closing the hinged bottoms of .the hoppers for receiving sheaves when they reach the lowermost portion of the track. The door 32 has an ear 47 formed thereon to which a spring 48 is connected. The spring 48 is connected, through the medium of a rod 49 to the circular plate 7 and it is provided for preventing the hinged bottom 32 from moving too great adistance away from the hopper 4 and also preventing the door from moving downwardly so that the rollers 34 carried thereby will properly engage the downwardly curved portion .46 of the track 35. r

The shock forming or sheaf carrying pan 46 is pivotally supported, by means of suitable rods 52, which are connected to the supporting structure as clearly shown in Fig. 11 of the drawings. The sheaf carrying pan 46 is preferably constructed of sheet metal and semi-frusto conical in shape, having the upper side thereof open for receiving the sheavesror bundles when deposited by either of the hoppers 3 or 4.

The pan 46 is normally held in a horizontal position, by an angled lever 56 which engages the upper surface of a bar '57. The

bar 57 is secured to and spaced outwardly from the outer surface of the side of the pan 46 facing the binder. The lever 56 is pivotally connected as shown at 57 to a supporting plate 58 which is carried by one of the braces 12 of the frame 13 of the binder, and has depending plates or arms 59 and 60, between which the bar 57 is seated. The lower angled end 61 of the lever 56 is heavier than the upper actuating end of the san'ie, so that it will move of its own accord beneath the bar 57, and hold the bar securely in place between the depending arms 59 and 60, for supporting the pan 46 in a horizontal position for receiving bundles or sheaves from the hopper structures 3 and 4. The construction and operation of this lever and the members associated therewith is fully shown and described in my patent above identified and need not, therefore, be more fully described herein.

The pan 46 has bearings 61", 62, 63, 64, 65, 66 and 67 secured to the outer surface thereof, in which bearings are rotatably seated coupling rods 67, 68, 69 and 70. The rods 67, 68 are connected by a. universal joint 68. The rods 68 and 69 are connected by means of a universal joint 71, and the rods 69 and 70 are connected by a universal joint 72. The rods 67, 68, 69 and 70 have sheaf engaging prongs 73 secured thereto, which extend through openings 74 formed in the pan 46, and are guided in their li'iOVQlllBlli'S means of outstanding guides 75, which are constructed of sheet metal and positioned upon the opposite sides of the openings 74.

The rod 7 0 has a cam 76 mounted upon its outer end, which has one end of a wire 77 connected thereto. The wire 77 is coiled intermediate its ends for forming a spring or resilient connection and the end of the wire which is free from connection with the cam 76 is connected to a compression rod 7 9which is positioned within the pan 46 for bearing against the tops of the sheaves or bundles of grain for holding them in proper position during the movement of "the pan 46 from a horizontal to a Nertical position, prior to the depositing of the bundles in shocks upon a field. The compression rod 79 is rockablv carried by the pan 4-6, so that upon rocking movement of the shaft 7 0, it will be moved into firm clamping position upon the tops of the bundles or sheaves of grain.

A. plate 80 is secured to the back of the outer surface of the pan 46 and it has plates 81 and 82 secured thereto in spaced. relation for forming a guideivay for a slidable bar 83. The bar 83 has its upper-end bent transversely to its main body portion as indicated at 84. The angled end 84 of the arm 83 is connected to the central link of the universal joint 71 by means of arod 85 for rocking the various coupling rods upon downward movement of the arm 83. A contracting spiral spring 86 is also connected to the central link of the universal joint 7' and to a rod 87, which is secured to the pan 416 in any suitable manner. The spring 80 tends to hold the coupling rods 67, 68, G9 and 70 positioned so that the prongs 73 will extend exteriorly of the interior of the pan 46. (See Figs. 2, 8, 4: and 5 of the above patent.)

The arm or plate 82 has a transversely extending lug 88 formed thereon substantially equi-distant of its ends, which lug is provided for engagement by a. pivoted catch or lug arm 89. The arm 89 is pivot-ally connected intermediate its ends to a bracket 90, which is secured to and extends outwardly from. the plate 82. A plate 91 is secured to the plates 81 and 82 and has its outer end slit, as shown at 92. The sections of the plate 91 upon the opposite sides of the slit or opening 92 have the inner edges of their outer ends curved outwardly, for forming arcuate approaches to the slot 92, as is clearly shown at 93. The outer end of the catch lever 89 has a head 9-1 formed thereon which is positioned for movement over the slot 92, for engagement with a bar 95, which is carried by a standard 96 at the rear end of the frame 13. The lower end of the plate or arm 82 is pivotally connected to a lever 97, which lever is in turn pivotally connected at 98 to a block 99. The end of the lever 97, which is free from pivotal connection to the arm 83, has a flexible cord 100 secured thereto. The flexible cord 100 extends upwardly from the lever, over the rod 87 and is connected to a rod 101. The rod 101 is slidably carried for longitudinal movement by bearings 102. The bearings 102 are carried by the side rails of the frame 13 and it extends to a position for conlvenient access by the person operating the self-binding harvester and the shocking attachment. (See Figs. 3 and 10 of the above patent.)

A flexible member or cable 101 is secured to the upper edge of the pan 46 and passes over a grooved pulley 105. The grooved pulley 105 is rotatably supported by a suitable bracket 106, which bracket is in turn supported by the frame 13. The flexible member 101 has a balancing weight 107 socured to its free end, for automatically returning the pan 4:6 to a horizontal position after a shock of sheaves has been removed therefrom.

In the operation of the improved shocker; when the self-binding harvester dischz'lrgcs a sheaf or' bundle of grain from the deck 1 thereof into either of the hoppers 3 or 4, it will move the trip finger 2 which will rock the lever 41-3 and through the medium of the flexible member 41 move the stop member 40 out of engagement with the pawls 39. The pawls 39 will then spring into engagement with the peripheral ratchet teeth 20 of the member 19 and consequently rotate the circular member 7 by the rotation of the combined gear and ratchet 19 which will carry the hopper that has just received the sheaf of grain from the binder upwardly until it moves off of the end 45 of the track 35, at which time the hinged bot tom of the hopper will move into an open position and allow the sheaf to fall into the shock forming and sheaf carrying pan 46. When the hopper that has just received the sheaf is in a dumping position, the other hopper will be in a sheaf receiving position, with respect to the binder, and the stops 10 will have engaged the pa-wls 39, forcing them out of engagement with the ratchet teeth 20 and allowing the combined ratchet and gear 19 to rotate idly. It will be noted, that the rotation of the circular member 7 and the movement of the hoppers is arrested upon each half rotation of the member 7, by the stop 40 so that one of the hoppers will always be in'a position for receiving a sheaf of grain from the binder deck while the other is in a delivering position for depositing the sheaf in the pan 1 6.

lVhen the desired number of sheaves or bundles have been de osited within the pan 46, for forming a shoe r, the rod 101 is moved,

longitudinally, which will operate the lever 97 upon its pivot and move the plate 83 downwardly within its guideway. The downward movement of the plate 83 will rock the tumbler rods 67, 68, 69 and 70. The rocking of the tumbler rods 67 68, 69 and 70 will force the prongs or tines 73 inwardly into the shocks, for preventing the shocks from falling out of the pan during movement of the pan from a horizontal into a vertical position; The rocking of. the tumbler rod 70 will cause the pin 103 to engage the actuating or operating end of the lever 56 and move this lever upon its pivot-a1 point 57, for moving it from beneath the bar 57. The rotation or rocking of the tumbler rod 70 will also rock the cam 76, which will force the compression members 78 and 79 into firm engagement with the tops of the sheaves, holding the tops in engagement with each other, for proper formation of a shock. The butts of the sheaves being of greater weight than the heads, will rock the pan 16 upon its pivotal connection 52 with the frame 13, and cause it to move into a vertical position. WVhen the pan 46 reaches a vertical position, the plate 95 will move between the forked ends of the plate 91 and into the slot 92, where it will be held in place by the catch lever 89, for a sufficient time to permit the pan to move away from the shock, which has been seated upon the ground, thereby leaving the shock standing. After the shock has been removed from the pan 46, the weight 107 will swing the pan from a vertical into a horizontal position, after the rod 101 has been again operated, for releasing the bar 95, for move ment out of the slot 92. The return movement of the pan, and the removing of the rod 101, will rock the tumbler rods for drawing the prongs 73 out of the interior of the pan 4:6. The lower head or angled end of the lever 56 has its under edge curved or rounded, to permit the bar 57 to ride thereover during the movement of the pan from a vertical to a horizontal position, and the head is of suflicient weight to cause the same to move outwardly beneath the bar 57, when the pan has reached a horizontal position, thereby holding the pan in position for receiving bundles from the hoppers.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved grain shocker, will be readily apparent to those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.
