SHEAF-DELIVERING GONVEYER- FDR SHOCKING MACHINES.

Application filed August 2, 192-3.

To QIZZ whom it may concern:

Be it known that I, FRANK RUssnnL GLASENER, a citizen of the United States of America, and a resident of Cedar Falls, Black Hawk County, Iowa, have invented certain new and useful Improvements in SheafDelivering Conveyers for Shocking lvlachines, of which the following is a specification.

My invention relates to improvements. in sheaf-delivering conveyers for shocking-machines, and the object of my improvement is to supply for a grain shocking-machine a conveying mechanism adapted to receive bound bundles of grain from a harvester binder and elevate and deliver them into the basket or shaping receptacle of the shock ing-machine, means being also provided to synchronize the movements of the conveyor relatively to those of the operations of the shocking-machine, by intermittently interrupting the progressive travel thereof; and means being supplied on the conveyer for ejecting bundles of grain carried thereon at a suitable location for discharging them into said basket or receptacle.

The above purposes have been successfully accomplished by the means and mechanisms which are hereinafter described and claimed, and illustrated in the accompanying drawings, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings: Fig. 1 is an elevation of the endless conveyer of my invention as viewed from the location of a binder delivering thereupon but not shown. Fig. 2 is a rear elevation of the conveyer and of the cooperating actuating mechanism therefor. Fig. 3 is a. detail view, on a. larger scale, of parts of said actuating mechanism. Figs. 4 and 5 are enlarged detail views of the adjustable connecting means between the carrying and the sweep arms of the endless conveyer, showing them respectively in differently adjusted positions. Fig. 6 is a detail elevation of the internally dentated clutch element and pawl device, and Fig. 7 is an elevation of the cam-wheel and follower elements, with the said clutch element and pawl shown in dotted lines. Fig. 8 is an edge elevation of the elements of said Fig. 7, omitting said follower elements.

In the above drawings, a harvester and Serial No. 35 5,296.

hinder which deliver bundles of bound grain to the conveyor are not shown, nor a shocking-machine to receive and form, shocks of handles discharged into it by said conveyer.

The mechanisms shown are mounted for transportation upon carrying-wheels, as at 9. while the bed or way of the endless conveyer is connected rigidly by means of hitch members 58 and 59 to the frame of a harvester to be propelled therewith to and fro.

The bed or way comprises an imperforate sheet metal apron 1 set at an inclination upwardly from a transversely concaved bundle receiving part, the upper end of the apron being directed horizontally to one side at- 2. and thence downwardly obliquely at 3 abutting upon an upper edge of a basket or receptacle 4, such as that of a shocking-machine mounted movably on said carryingwheels to the right. Mounted upon said apron 1 are a pair of spaced longitudinally directed tubular elements 5, adapted to receive thereon bundles of grain, the bundles being pushed therealong by the conveyer carrying arms to the point of discharge, the tubes keeping the bundles spaced from the apron 1, diminishing friction and frictional wear of the apron.

sidebars 68 are rigidly supported at opposite ends at front and rear of the apron 1 and have bearing-boxes thereon at 64 to re ceive the shafts 62 and 68, the shaft 62 carrying a sprocket-wheeel 61 driven by a sprocket-chain and sprocket-wheel 13. Pairs of sprocket- wheels 65 and 66 are mounted on said shafts 62 and 68 at opposite parts of the apron 1 and carry the endless conveyor chains 67. Tubular elements 74 and 85, arranged in three pairs, are positioned in spaced relation transversely across the chains 67 and are secured to special links of the latter which have rigid standards 75 thereon directed at right angles thereto outwardly.

Referring to Figs. 4 and 5, the tubular elements 7% are rockingly mounted in sleeves which are fastened on said standards 75. For a purpose to be described, fiat longitudinal bars 77 are secured by bolts 76 along said elements 74. Several carrying arms 73, preferably shaped from resilient rods, are terminally coiled about the elements 74, transversely spaced apart, and have the extremities of their coils inserted in and secured by holes in said bars 77, so that the arms normally are projected outwardly at about right angles from the endless conveyer, having their free end parts slightly curved to ward the direction of their travel with the conveyer.

The others of the pairs of elements shown at 85 are likewise mounted rockingly in sleeves secured on standards at a distance of several chain links from the other element 74. The elements 74: and 85 are connected by the following means. The numerals 79 and denote connected sections of sectional links between the elements 74c and 85, being short bars twisted to have their abutting end parts in spaced parallel relation, and clutch-disks 83 are secured respectively thereto on their opposite faces and have co-mating radially dentated faces, the disks being secured together as adjusted relatively by bolts 81 and the nuts 82. The other end of each bar section 79 is shaped as a sleeve member 78 mounted loosely upon the element 74, while the outer end of the other bar section 80 is shaped into an elongated loop 84.- in which the element is slidably mounted. It will be observed that the sectional linking means keep the two elements 7 1 and 85 at constant positional relation to each other, and that the clutch-disks permit angular adjustments of the elements 74 and of the carrying arms 73, so that the angle of the arms may be varied as found necessary relative to the endless conveyer and according to the burdens to be moved or the proper clearance thereof in use, and that the loops 84 afford the necessary shifting of the sections 80. V

The elements 85 have transverse holes to receive the members or arms 86 of the U-shaped rods 88, the arms 86 serving as sweeps for the carrying arms 73, and normally being positioned to cross the latter close to the elements 7 1, being kept yieldingly in this position by means of tension springs connected to the bars 77. The left-hand end of each tubular element 85 is bent into a crank 89 projecting inwardly relative to the conveyer. The numeral 69 denotes a cam-plate or tripping-device which is rigidly mounted at the left-hand upper angle of the conveyer frame in the path of progressive movement of the crank 89 to trip or rock the latter together with the element 85 and the sweep arms 86 at that location, whereby the arms 86 are caused to swing outwardly across and along the carrying arms 73 to discharge the burden carried onthe latter arms, such as a bundle of boundgrain, into the open top basket or shaping receptacle 4 of the shocking machine. When the crank 89 has been carried forward by the conveyer far enough to clear said cam-plate 69, the reaction of the stretched spring I 90 swings back the sweep arms 86 to their initial positions.

Referring now to Figs. 2, 8, 6, 7 and 8, the carrying wheels are positioned at 9 to the right of the bed or way of said conveyer, one wheel 9 only being shown,'and which supplies the driving power for operating the conveyer as also for the moving parts of the shocking machine not shown. The wheel 9 referred to has its axle 10 rotatably mounted in bearing holes in the members of a U-shaped framebar 8,0ne end of the axle carrying a sprocket-wheel 4 -1 and the other end carrying a bevel-gear 11. The U-shaped member 8 is hung on hangers 7 and 19 having bracket-bars 1-1 and 57 which together with a standard 6 support the lower and upper ends of the bed or way of the conveyer.

A shaft 13 is mounted in a bearing suspended from the bracket-bar 57, and car ries on its forward end a bevel-pinion 11 in mesh with said bevel-gear 12. The sprocket-wheel 16 is mounted loosely and longitudinally slidably'on the rear part of the shaft 18 and has a hub clutch-face 15 dentated to mate with a dentated clutchface on a sleeve 14 fastened on said shaft. A flanged collar 18 is riveted on the rear extremity of said shaft, and a coiled compression-spring 17 is mounted on theshaft engaged bet-ween the'collar 18 and the sprocket-wheel 16. A sprocket-chain 60 connects the sprocket- wheels 61 and 16. Plates 30 and 31 are fastened on the hangers 19 and 7 respectively and have alined bearing orifices to seat the middle horizontal part of a rock-shaft 28 which hasoppositely projecting crank parts 27 and 29 extending respectively downwardly and up wardly, the upper end of the crank 29 being bent over angularly and carrying a rotatable cam-roller or follower 32.

On the lower crank 27 is a loop 26 which re eives and supports the upper looped part of a medially bent fork 21 whose lower ter minal forks embrace the clutch-hub 15 of the sprocket-wheel. 16 to bear against the adjacent" face thereof, and opposing the tie tion of the spring 17 at times. A coiled tension spring 20 is connected between said loop 26 and the hanger 19 and acts to tension the crank 27 rearwardly and keep the roller 32 on the upper crank 29 in bearing contact with the circumferential cam edge of a cam-wheel the latter being loosely and non-slidably mounted on a fixed shaft 3 1 abutting a stop-collar 85, the shaft 34.

with a stop-sleeve thereon being mounted in V a boxing 36. On a bracket 37 is pivoted a bell-crank lever 38, an operating pull-chain 39 being connected to one memberthereof. and a link 10 connecting the other member thereof to the crank 29.

A sprocket-wheel 42is mounted loosely and non-slidably on the shaft 34 and has on one face an open end cylindrical clutchmember or ring 54: having internal teeth A pawl arm is pivotally mounted on the cam wheel and has a roller 53 mounted rotatably on one face to at times engage between teeth 55 on the member 54. A tension spring 51 is connected between said arm and a bolt 50 on the cam-wheel to normally retain the roller engaged with said teeth The ram-wheel 33 has opposite cam edges at is and 19, concentric axially but with different radii and joined by a shoulder ll on one side, and on the opposite side by a pro jection 4-5 with adjacent hollow and shoulder at -16.

The carrying wheel 9 drives the gearing il-12, shaft 13 and sprocket-wheel 16, the latter being normally clutched to said shaft by tension of the spring 17, as the forks 21 are medially fulcrumed in bearing openings in a flange-plate 22 adjustably mounted on an angle-plate with spacing washers 23 on connecting bolts 24. The sprocket-wheel 16 by means of the chain 60 drives the sprocket-wheel 61 and shaft 62 to advance the endless conveyer. The pull-chain 39 may be used in order to rock the crank 2? oppositely to cause a rocking of the forks 21 oppositely to push the sprocket-wheel 16 out of clutch while compressing the spring 17.

The cam-wheel is used to impart certain movements to the movable parts of the shocking-machine not shown, as the vari ous projections and hollows of the cam edge act upon the follower roller 32 in pushing it outwardly or allowing it to return inwardly under the tension of the spring 20. This causes an intermittent connection and disconnection of the sprocket-wheel 16 relative to the shaft 13, to effect intermittent action of the endless conveyer at times when related movements of the shocking-machine are made. The conveyor is thus automatically intermittently controlled as necessary in the operation of the shocking-machine, and in the proper delivering of bundles of grain to the latter in synchronizing the actuations of these mechanisms.
