6 Claims.

This invention relates to sacking machines and is particularly adaptedto be usedin connection with combines and the like.-

The primary object of the invention is to provide a mechanism that will accommodate two or more sack holders thereon;

Another object of the invention is to provide a mechanism wherein while one sackis being filled another sack can be sewed.

A still further object of the invention is to provide a mechanism that will-shake the ma terial being fill-ed into the sack towards the bottom of the sack, at the same time the sack is being filled.

A further object of the invention is to combine a sack sewing platform with-the sacking operation in one compact unit.

These and other incidental objects will be apparent in the drawings, specification and claims a to follow.

Referring to the drawings:

Figure 1 is a plan view of the sacking mechanism mounted on a platform, for instance a combine.

Figure 2 is a sectional view, taken on line 2-2 of Figure 1, looking in the direction indicated.

Figure 3 is a detail plan view of the s ack holding clamp.

figure 4 is an end view, looking in the direction indicated, takenonline 4-4 of Figure 1.

Figure 5 is a plan detail view of the raising and lowering mechanism.

Figure 6 is a fragmentary sectional view of the turntable locking mechanism.

In the drawings:

I is the combine having the usual grain elevator 2, and the usual sacking platform 3, upon which my new and "improved sucker is mounted. Within the platform built a circular track 4, above which is mountedthe platform or turntable 5. The turntable revolves upon the trunnion wheels 6, which are mounted upon the turntable by suitable brackets I, and run on the circular track 4; A supporting column 8 is fixved ly mounted to the center of the turntable 5 by the hub 9, said hub 9 being securely fixed to the turntable by the flange ll]. of the pedestal 8 may be rotatably mounted within thebearing H. The bearing may not be necessary, but I show the same in this drawing for the purpose of making the assembly more rigid.

Two additional upright columns l2- are fixedly The lower end 1 on the main column 8 by suitable fastening means I Guide rollers l8 are mounted-upon the arms l5 and bear against the inner surface of the guide plates It. On the outer ends of the arms |-5, rollers lflware rotatably mounted, the pur- 6 pose of which will be later described.

On the upper ends of the plungers Hl are mountedsack holder mechanism, which we will now describe. Circular ring 20, about which the sack 2| is positioned for holding the sack, is 10 mounted onthe plunger by the arm 22 and held in an adjusted position by the collar 23 mounted upon the plunger I4. The collar is held in any desired position by the hand set screw 24. After the sack has been placed about the ring 20, a

secondary ring 25 is placed thereaboutand locked thereon by :a lever 26, mounted within the hinged link 21, which in turn ishingedly connected to the band 25 at 28. The end 29 of the lever 25 engages thehook 30 of the opposite end of the ring 25, after which the lever 26 is forced past center bringing the ends. of the ring 25 together, similar to a brake band. The friction engagemerit members 3| will then bear against the sack I, which is trained about the inner ring 5 2!) locking the same therebetween.

The ring 25 is mounted to a bracket 32, which is p-ivotally mounted lo the slidable sleeve 33 at 34, as shown in Figure 4. The sleeve 33 is raised allowing the bracket 32 land the ring 253 3 0 to be movedaway from the ring 20, and a holdingarm 22A is provided for the purpose of holding this unit in a raised position, so that the sack 2| can be replaced or taken oil. Raising the bracket arm 22 upward on the plunger I4, 35 thus disengaging the dog 35, from a corresponding notch within the sleeve 23, allows the revolving of the brackets 22 and 32 about the plunger so that the rings 20 and 25 can be moved away from the sack 2| allowing access to the sack for sewing :and removing, The sacks 2| rest upon special guides or receivers 36 that are shaped to conform to the bottom of the sack, and these guides are in turn fixedlyv mounted to the upper surface of the turntable 5.

In my new and improved sacker, the primary object is to not only hold thesack but also to shake the contents of the sack towards the bottom of the same permitting a more solidly filled sack and this is accomplished in the following, mannor. The arms I5, having the rollers l9 mounted thereon, are brought into engagement with a cam 31, .and as the cam revolves in the direction indicated it will raise the arms I5 and the plungers lijas shown in Figures 2 and 4. When the cam reaches the point shown in Figure 2, the rollers l9 will drop ofi of t the end 38 allowing the plunger M to fall quickly. dropping the bottom of the sack upon the receiver or brackettli. This forces the contents of the sack towards the beta tom, packing the same as if it were being done by hand. By observing the shape of the cam it will be noted that as the cam revolves it will repeat this operation, raising the plunger slowly and dropping it quickly. 'Iheplunger or sack holder that is registered with the filling spout 39 is the one that will be agitated as just described. The opposite sack holder, which is one hundred and eighty degrees opposite, will be stationary, as its raising and lowering mechanism is out of engagement with the cam 31. This permits the disengagement of the sack from the holding rings and revolving them out of position, as before described, and the sewing of the sack by the sewer can then be accomplished, after which the sack is tipped over into the chute 40 and another sack secured to the rings 20 and 25 and locked thereto as heretofore described.

In order to settle the materials being filled into the sack towards the bottom of the sack it is desirable to drop the sack forceably after the cam 31 reaches the top, but it is also desirable to hold the upper part of the bag under tension when this operation takes place. Therefore the plungers M are held in raised position by the springs 4|, having their upper ends secured to the lower side of the turntable 5 and their lower ends connected to the arms I5 of the plungers l4. When the sack under the hopper 39 is filled to the desired point the operator or sack tender takes hold of the handles 42 and revolves the turntable 5 one hundred and eighty degrees in the direction of the arrows. This movement can not take place until the cam 31 has raised the arm IE to the top position, due to the fact that the roller 43 engages the front surface 44 of the frame 45, best shown in Figures 2 and 4, when the arm l5 reaches the top. The rollers 43 can then be forced over and upon the inclined surface 46 of the frame 45. The downward weight of the filled sack 2IA will assist in the revolving of the turntable from there on due to the fact that the roller 43 holding the arm l5 from downward move- .ment will be running down the inclined surface A suitable shut-off valve 41 is provided for shutting off the supply while the turntable is being revolved, taking a filled sack away and bringing in an empty one underneath the spout 39.

The cam 31 is driven by the driving sprocket 52, which may be any suitable drive relative to the combination of the sacker with the combine. A chain 53 drives the sprocket 54, which is fixed to the cam 31.

The turntable 5 is held from turning by locking dogs 48 underneath the brackets 36. The dogs 48 register with notch 49 of the foot pedal 50, and when the foot pedal 50 is pushed down against the spring 51 the notch 49 will be released from the dog 48 permitting the turntable 5 to be revolved.

I do not wish to be limited to this particular form of mechanical embodiment, as other types of construction could be employed, still coming within the scope of the claims to follow.
