\sw mmim kZQQ PIVOTABLE BUCKET WITH ROTATABLE SIIREDDER BLADE AND EARTH EJECTOR This invention relates to earth moving machinery; more particularly, to earth moving machinery adapted to general excavation, ditching, pipe lines, and the like; still more particularly, to machinery in the form of a pivotable bucket that is secured to and operated by a power boom of an earth moving carrier vehicle, said vehicle embodying such a power boom.

It is a well known fact by those experienced in the art of earth moving that one of the ever present problems of an earth mover is to remove the maximum amount of earth in a minimum of time with a minimum of effort and equipment.

It is therefore the principal object of this invention to provide a pivotable bucket, having rotatable earth moving mechanism, of the character described that is not required to go down in the earth, load the bucket, and bring it up and out of the excavation; swing to the fill; place the load; and swing back to the excavation. Thus a time consuming operation for the removal of earth or the like is eliminated by my invention. There is also provided a controlled continuous flow of earth or the like to a predetermined location.

Another object of this invention is to provide a bucket of the character described that is connected to an elbow type of power boom secured to an excavator or other desired vehicle or the like of any desired size and shape.

Another object of this invention is to provide a bucket of the character described that is operated by a hydraulic system or a system using air or mechanical means.

Another object of this invention is to provide a bucket of the character described, the bucket to be used for work such as ditching, mosquito control, reclamation work, putting out forest fires, making fire lanes and the like. This is possible because of the buckets ability to provide a controlled steady flow of mud that can be directed over a wide area or can be piled close by the ditch, if it is so desired.

Still another object of this invention is to provide a bucket, having rotatable earth moving structure, of almost any shape and size that can be attached to various excavators, bulldozers, and front end loaders to provide a continuous flow of earth or whatever material that is dug up by the bucket.

Other and further objects and advantages of this novel invention will no doubt appear as the reading of this specification and its appended claims proceeds and the accompanying drawings are examined in connection therewith.

In the drawings:

FIG. 1 is a pictorial view of this invention, secured to the boom of a carrier and in typical use.

FIG. 2 is a front view of this invention, as viewed in the direction indicated by the arrowed line and the number 2 in FIG. 3.

FIG. 3 is a sectional view of this invention, taken substantially along line 3-3 of FIG. 2, and viewed in the direction indicated by the arrows.

FIG. 4 is a pictorial exploded view of this invention.

FIG. 5 is a side view of the shredder blade and a portion of its supporting structure, as illustrated in FIG. 3, except that here in FIG. 5 the shredder blade is shown cutting into the earth.

FIG. 6 is a sectional view of that detail of this invention hereinafter known as the shredder blade, substantially taken along line 66 of FIG. 4, and viewed in the direction indicated by the arrows.

In the several views of this invention, like parts of the invention are indicated by like reference numbers. The reference number 10 indicates this invention in its entirety.

Looking first at FIG. 1 of the accompanying drawings it will be seen that this invention 10 consists of a bucket 11 in which is located hereinafter described rotating structure. The aforesaid bucket 11 is provided with an upwardly disposed and outwardly projecting discharge chute 12, having an adjustable and thus controlled deflector 13 mounted on the top side thereof for the purpose of deflecting earth and the like, being dug up by the bucket, to any desired location on top of the ground in which the excavation is being made. The back of the aforesaid bucket 11 is provided with a back wall l4 to' which is bolted a reduction drive case 15 for the support of the shaft bearing 16 and the encasement 15 of the reduction drive 17. The open forward end of the aforesaid bucket 11 is provided with removable earth cutter blades 18 on the front face and outer end of each ejection blade 19, described hereinafter in this specification.

The rotating structure of this novel invention has been mentioned but not yet described in detail. This just-mentioned structure consists of a horizontally disposed shaft 20 that is supported by two bearings, namely, the aforesaid shaft bearing 16 that is mounted on the wall of the aforesaid reduction drive case 15 which is basically rectangular in configuration. The already-mentioned shaft 20 is also supported by the forward support bearing 21 that is located in the aforesaid back wall 14 of the bucket 11. A part, which I personally call the rotating wheel structure 22, is provided with a plurality of outwardly extending ejecting blades 19. The aforesaid blades may be formed integrally with the rest of the wheel structure 22 or else secured by bolts or rivets to the body of the wheel. A shredder blade 23 of unique configuration, when viewed from the side, is secured by shear bolts 24 to the outer surface of the hub 25 which is mounted on the outer end of the aforesaid shaft 20 of this invention.

A combination shear blade and compression plate 26, having a sharp lower edge 27, is bolted onto the face 28 of the housing 29. Although not previously mentioned, the aforesaid combination shear blade and compression plate 26 has the configuration of a trapezoid. It should also be mentioned at this time that while I have previously stated that the bucket 11 is provided with an aforesaid discharge chute 12, the justmentioned discharge chute 12 is actually a part of the aforesaid housing 29 which fits into the aforesaid bucket 11 and thus becomes a part of the bucket.

Directing ones attention now to FIGS. 3 and 4 of the drawings it will be seen that this invention is provided with a hydraulic motor 30 or its equivalent that has its power shaft 31 supporting a sprocket over which the chain 32 is placed as a means of rotating the aforesaid rotatable structure of this invention. These justdescribed details of this invention obviously comprise the mechanism of the reduction drive of the invention. The aforesaid chain 32 also encompasses in part a larger sprocket that is located on the aforesaid horizontally disposed drive shaft 20 of this invention.

The only parts of this novel invention that so far have not been described or even mentioned are the power boom 33 of the vehicle to which this invention is attached and the hydraulic cylinder 34 that controls the digging angle of the aforesaid bucket 11. Going back to the aforesaid power boom 33 it will be seen by looking at FIG. 1 of the accompanying drawings that the invention has its-bucket pivotabaly cured to the outer end of the just-mentioned power boom 33 by means of a laterally-disposed coupling pin 35 whose outer ends project through the upper front sides of the bucket 11. The hydraulic cylinder 36 controls the angle of the aforesaid adjustable deflector 13, the aforesaid hydraulic cylinder 26 being controlled by the operator of the bucket at his control station.

The controlling digging angle of the bucket 11 is obviously done by the operator of the invention when it is in use.

The way in which this bucket is used is so obvious to those experienced in the art upon examination of the accompanying drawings that no explanation of its use is considered necessary or is given in this specification.

This invention is subject to any and all changes in detail design, construction, and/or modifications that one may care to make in so long as the changes and/or modifications all fall within the scope and intent of the appended claims.
