LEO CiESLAK Patented Mar. 29, 1949 UNITED STATES PATENT OFFICE This invention relates to conveyors for combine headers and is particularly related to combines of the type having a straight feed or scoop shovel header.

The primary object of the invention is to provide an auxiliary conveyor located adjacent the cutter bar of the header, making it possible to cut the grain with a minimum amount of straw attached to the head, as in the case of cutting the grain high to avoid weeds and foreign growth entering the header.

Another object of the invention is to provide means adjacent the cycle guard for eliminating the plugging up of the space between the guard and the end of the main conveyor or elevating canvas.

A further object of my invention is to provide means for preventing the short grain piling up adjacent the cycle bar and rolling down underneath the header over the bar.

A still further object of my invention is to provide means for the feeding of the grain from the cycle bar up the conveyor or canvas evenly so that there will be less clogging of the cylinder drums.

And a further object of my invention is to provide means facilitating the cutting grain of shorter length than has heretofore been possible with this type of combine.

These and other incidental objects will be apparent in the drawings, specifications and claims.

Referring to the drawings:

Figure 1 is a fragmentary diagrammatic side view in elevation of a combine header having my new and improved conveyor assembly mounted thereon, parts broken away for convenience of illustration.

Figure 2 is a fragmentary plan view of Figure 1.

Figure 3 is a fragmentary enlarged sectional view taken on line 33 of Figure 2.

Figure 4 is a fragmentary sectional view taken on line 44 of Figure 3, parts being broken away for convenience of illustration.

Figure 5 is a fragmentary sectional view taken on line 5-5 of Figure 2 parts being broken away for convenience of illustration.

Figure 6 is a sectional view taken on line 6-6 of Figure 4 of my new and improved auxiliary conveyor.

Referring now to the drawings, specifically to Figures 1 and 2, the present invention is primarily concerned with a straight feed scoop shovel type combine I having the usual header 2 to which my new and improved auxiliary conveyor or canwas 8 is attached. My auxiliary conveyor 3, as

best shown in Figures 3-6, consists of two side frame members 4 spaced by the cross bars 5 and 6. Tubular members 1 form part of the side frames 4 and are joined to the cross members 5 and 6 at 8 and 9. Journalled within one end of the frame assembly is a roller l0. Stub shafts l I are fixedly mounted within the ends of the roller H), as by set screws I2, and are journalled within the bearings l3 of the side frames 4 and also in the bearings 14 in the forward end of the frame 15 of the header 2.

In the opposite ends of the frames 4 bearing blocks it are slidably mounted in guideways H in the frames 4. The two bearing blocks l6 are joined together by the cross members l8, providing an integral unit. An idler roller 19 is journailed in the bearing blocks l6 by the stub shafts 20 being threadably mounted to the blocks at 2| and operating within the bearings 22 of the roller 19. A canvas 23 is trained about the roller l0 and the roller l9 and is maintained in a taut condition by the action of the springs 24 nesting in the tubular members 1 on their one end and against the cross member 18 at their opposite end to the center or guide pin 25.

My new and improved auxiliary conveyor or canvas is pivotally mounted to the header of the combine by the action of the stub shafts H working within the bearings I4. The opposite end of the conveyor assembly is free to float up and down between the side frames l5 of the header. Brackets 26 are fixedly secured to the inner side of the frames l5 to freely support the frames 4 of the conveyor assembly under normal conditions, but the frames 4 are free to raise from the brackets 26, including the complete conveyor assembly, to permit the passing of materials thereunder. The roller I0 is the driving roller and is driven by the chain 28, driving the sprocket 29 fixed to the shaft H, said chain being driven from the sprocket 30 which in turn is driven by a suitable belt 3| from other parts of the combine.

The regular conveyor or canvas of the header is indicated at 32.

My auxiliary conveyor, as best shown in Figure 3, is mounted forward and above the lower end of the conveyor 32. The sides of the header are bridged crosswise by the pan 36 which consists of a bottom 34 and front 35. Extending transversely of the header and between the side walls of the same is a grain guard 39 which is hingedly secured to the bottom 34 of the pan 36 by a hinge 40. Extending transversely of the header and secured to my auxiliary conveyor is a grain guard 4|, this guard is secured to the under side of the frames 4 of my auxiliary conveyor at 42. This guard has a radius, indicated by the broken line arrow in Fig. 3, about the pivot shaft H of the conveyor. Consequently, as the floating end of the auxiliary conveyor is raised or lowered, the guard 4| will register with the edge 43 of the grain guard 39 and form a seal therewith during its movement. The bottom 34 of the pan 35 may be perforated to allow foreign matter to escape therefrom, such as dust, chaff and the like.

I will now describe the operation of my new and improved auxiliary conveyor. As the heads less conveyor floatingly mounted in the front end of said trough with one end immediately in back of said mower bar and the other end overlying the front end of said main conveyor to deliver cut grain from said mower bar to said main conveyor, whereby to permit removal of I trash in the front end of said trough.

of the grain are removed from their stalks they fall directly on the canvas 23 of my new and improved auxiliary conveyor and are delivered from this canvas onto the elevator canvas 32 of the header.

By the use of my auxiliary conveyor, the chaff and grain that returns down over the bottom 33" I of the header will enter the space 44 at the lower end of the canvas conveyor 32, and as the slats of the conveyor revolve they will pull the same around past the transverse grain guard 39 and under the grain guard 4! attached to my conveyor at 42, directing the grain back up with the a conveyor 32 without jamming the same, due to the fact that the upper end of my auxiliary conconveyor is not in any way interfered with by the returning of the grain and chafi down under the header conveyor as above described, and, at the same time,due to the fact that this auxiliary conveyor is pivotally mounted and can raise and lower with the returning chaff from under the canvas and space 44 of the header, jammingof the same is reduced to. a minimum.

I do not wish tobe limited to the exact mechanical structureas illustrated anddescribed; as other mechanical equivalents may be substituted still coming within the'scope of my claims.

I claim:

.1. In an implement of the type including an inclined pick-up header composed of 'a trough, a mower bar across the lower, front end of .said trough, and a main driven endless conveyor ex-' tending the length of said trough to carry material cut by said mower bar up to be discharged at the upper end thereof, the combination of the improvements comprising a driven auxiliary end- 2. An implement as defined in claim 1 wherein said auxiliary conveyor is ,pi.votal y mounted at its front end.

3. In an implement of the type including an inclined pick-up header composed of a trough, a

mower bar across the lower, front end of said tro'ugh',.and a main driven endless conveyor extendin the length of said trough to carry material cut by said mower bar up to be discharged 'at theaupper end thereof, the combination of the improvements comprising a driven auxiliary endless conveyor pivotally mounted at its front end immediately in back of said mower bar and the other end overlying the front end of said main conveyor to deliver cut grain from said mower ,bar to said main conveyor, whereby to prevent dropping and jamming of trash in the front end of said trough, an upstanding lower guide plate secured across the bottom of said trough beneath said auxiliary conveyor and spaced front of said main conveyor, and an upper guide plate carried across the underside of said auxiliary conveyor and extending downwardly to engage said lower-guide plate to form a complete guide-around the end of said main conveyor during the pivotal movement of the.
