17 Claims, 5 Drawing Figures LANDFILL BUCKET The present invention relates to buckets adapted for attachment to the front of vehicles such as loaders.

Loaders of a wheeled or track type are widely used I for digging, hauling and spreading of earth. Buckets and blades have been especially designed for special tasks and interchanged depending upon the task to be performed. The disposal of solid refuse is an increasingly greater problem for metropolitan areas and even smaller municipalities. A common practice currently in use is to dig a trench, to fill the trench with refuse, and to bury it by covering the refuse with loose dirt.

It is the principal object of the present invention to provide a novel bucket which is so constructed as to .function efficiently in the disposal of solid refuse and to function not only as a loading bucket, but also as a digger and a hauler. The increased height of the bucket of the present invention permits the loader vehicle to push more refuse than can be pushed with a regular bucket or conventional dozer blade. and at the same time the bucket can doze, spread and segregate refuse efficiently.

It is another object to provide a novel bucket wherein the wrapper member is angularly related to the floor member at their line of intersection, has an arcuate or curved surface which is much smaller in extent than the rear wall of the bucket, and has a radius approximately equal to the floor .depth to thereby give increased height for refuse capacity.

A still further objectisto provide a novel bucketwherein the cutting blade protrudes in front of the side plate members and the side plate members are notched or provided with a recess to facilitate the segregation and carrying of refuse such as refrigerators, trees and other objects that normally cannot be carried with a standard bucket.

Yet another object is-to provide a novel landfill bucket with notched side plates and a top wall that extends much further than is customary to thereby increase the capacity that would otherwise be lost becauseof the smaller side walls and that is perforated to prevent curtailment of visibility. The top hinge pin is located internally of the bucket to also increase capacity and allow for the necessary tilting of the bucket for hauling. I

Yet a further object-is to provide a novel bucket having an extended front cutting edge and recessed side plates for segregating material, a floor section of flat plate material reinforced by wear plates for strength will be more fully apparent from the claims and from i the description as it proceeds in conjunction with the drawings, wherein:

FIG. 1 is a pictorial view of the landfill bucket of the present invention mounted on the front of a track type loader;

FIG. 2 is a side elevation of the landfill bucket of FIG. 1;

FIG. 3 is a side elevation showing the bucket in a car-' rying position on the front of a loader;

FIG. 4 is a view similar to FIG. 3 showing the bucket in its dump position; and

FIG. 5 is a view similar to FIG. 3 showing the bucket in its digging attitude.

DETAILED DESCRIPTION Referring now to FIGS. 1 and 2, the landfill bucket 10 of the present invention is shown on the front of a track type vehicle 12; which is of conventional construction. Landfill bucket 10 is an attachment which is interchangeable with dozer blades, loading buckets, snow plows, and like implements customarily used with loaders and tractors. The vehicle 12 has a pair of pusher arms 14 and tilt jack arms 16 which are conventionally controlled by the vehicle operator. The landfill bucket 10 is attached in a conventional manner through the use of hinge pins at 18 and 20 to pusher arms 14 and tilt jack arms I6, respectively.

The bucket 10 is fabricated from a bucket wrapper member 22 which has a surface that is curved so as to provide proper action when dozing. In the illustrated embodiment, wrapper member 22 is part of a cylinder having a horizontal axis 24 and extending across the entire width of the bucket.

Wrapper member 22 is provided with a pair of openings so that the top hinge pins 20 are located forwardly of the front wall of wrapper member 22.

At the lower end of wrapper member 22, there is a floor member 26 which provides a substantially flat loading surface out to the cutting blade 28. The upper surface of cutting blade 28 constitutes a continuation of the flat floor of the bucket and extends forwardly of the wrapper member axis 24 as is illustrated in FIG. 2.

Floor member 26 preferably has a portion 30 which extends behind the lower end of wrapper member 22 and is bent to have an upwardly extending portion 32 that terminates upon contact with the rear surface of the wrapper member 22. A plurality of reinforcing steel gussets 34 are used as needed to support the back wall of the lower portion of the wrapper member 22. Lower edge 36 of wrapper member 22 is, also preferably welded to the upper surface of floor member 26.

On the back side of the bucket 10, four identical hinge plates 38 are installed as pairs. The two hinge plates 38 in a pair are mounted a few inches apart to be immediately adjacent opposite sides of the pusher and tilt jack arms and to hold the

hinge pins

18 and 20. Each hinge plate 38 has a lower portion to which hinge shoes 40 are welded. In approximate alignment with hinge shoes 40 are wear plates 42 which extend forwardly to the rear of cutting blade 28.

Hinge plates 38 extend upwardly from the forward end of hinge shoes 40 and are welded to the upwardly extending portion 32 of floor member rear portion 30 and to the rear surface of bucket member 22. Hinge plates 38 then pass through the opening'in the wrapper member to extend into the interior. of the bucket, as shown in FIG. 1, and are welded to the front surface of wrapper member 22. The space between the hinge plate pairs is filled by use of flat plates 44.

Hinge plates 38 extend upwardly from pin 20 through wrapper member 22 and are secured to the rear surface of wrapper member 22 and reinforced where necessary by suitable gussets 46, all by conventional welding techniques.

A pair of substantially

identical side plates

48 and 50 are secured as by welding to the opposite side edges of wrapper member 22 and floor member 26. Each side plate-has a leading edge, located at the surface of floor member 26 and cutting blade 28, which extends upwardly at an oblique angle relative to the vehicle direction. In FIG. 2, the oblique angle between edge 52 and the floor surface is shown to be about 120. Edge 52 extends generally upwardly and rearwardly a distance on the order of l to 2 feet, depending on bucket size, and may be curved or straight as illustrated. The upper point of edge 52 meets at junction 54 with the lower point of leading edge 56. The leading portion of the side plates having edge 56 is disposed in a direction generally perpendicular to the upper surface of floor member 26 and, if extended, would intersect with the upper surface of floor member 26 at a point which is substantially forward of the line of intersection 36 of wrapper member 22 with floor member 26. The region at junction 54 serves as a recess whose function will be discussed in connection with FIG. 3.

Along the leading

edges

52 and 56 of

side plates

48 and 50 are reinforcing

bars

58 and 60, respectively, which strengthen the bucket and add rigidity to the side plates. Reinforcing bar 58 extends from cutting blade 28 past junction 54 to the edge of wrapper member 22. The particular size of the oblique angle is not critical, but advantages accrue from using the illustrated angle since reinforcing bar 48 is disposed so that it provides important added strength to its side plate.

Cutting blade 28 has a forward edge 62 which may be sharpened as by having a bevel. Cutting blade 28 extends forwardly of the lower leading edge 52 of the side plates by a distance approximately one-half as great as the length of oblique edge 52. The distance from cutting plate edge 62 to the intersection line 36 at the lower edge of wrapper member 22 and floor member 26 is approximately equal to the radius of the wrapper member. Since the lower portion of the wrapper member 22 is not tangent with the upper surface of floor member 26, the axis 24 of wrapper member 22 lies in a vertical plane which is considerably behind the cutting blade edge 62, and in the illustrated embodiment, is at the rear edge of cutting blade 28.

The rear half of cutting blade 28 is secured to the underside of

side plates

48 and 50. Extra strength is obtained from

gussets

64 and 66 along

side plates

48 and 50, respectively, which are welded to cutting blade 28, floor member 26, and the adjacent side plate. Additional support for and to prevent bowing of cutting blade 28 is provided by angles 68 which are welded to blade 28 and floor member 26 and plate 70 which is welded to angle 68 and to blade 28, floor member 26 and wrapper member 22.

The forward half of the cutting blade 28 protrudes in front of the

side plates

48 and 50 to thus give the operator exposed side edges 72 and 74 to work with for purposes of segregating material and to facilitate moving the cutting blade under bulky items such as logs or household refrigerators found in solid waste disposal areas and loading of such items on the bucket for haulmg.

Attached to the upper portion ofwrapper member 22 is a protective screen 76 which may be of expanded metal supported by suitable braces 78. The direction of the screen may be along a 45 line to give increased bucket capacity and still miss the radiator guard on the vehicle when the bucket is in its carry attitude, as shown in FIG. 3. The upper edge of the screen 76 lies in a vertical plane that passes through cutting blade 28.

In FIG. 3, the bucket 10 is shown on the front ofa vehicle 12 which is commercially available and delivered with pusher arms 14 and tilt jack arms 16 which have relative dimensions substantially as illustrated. The bucket 10 is adapted to carry earth or trash, as shown by dotted line 80. In order to move the protective screen 76 on the bucket back near the radiator guard on the vehicle and thereby increase the bucket capacity, the tilt jack arm pivot pin 20 must be located forward of the front wall of the wrapper member. in this position of the bucket, the protective screen is substantially vertical.

instead of earth of trash, the bucket 10 is adapted to haul a log, which can be of substantial size. depending on the size of the bucket. In this position of the bucket, edge 52 on the side plates can be made very nearly horizontal while cutting blade 28 is raised to a range between 45 and depending on the angle of pusher arms 14 and tilt jack arms 16.

As shown in FIG. 4, the pusher arms 14 are shown in their elevated position. After the bucket is raised, the tilt jack piston rod may be extended to thereby tilt bucket 10 to its illustrated dump'position.

With reference to FIG. 5, bucket 10 is shown in its dozing or digging attitude while attached to the same vehicle, as shown in the other figures of the drawings. Cutting blade 28 is shown operating below ground line 82, nd the bucket being as wide, or wider, than the vehicle tread, gives protection to tracks and rollers, and

is thus able to serve as a dozer blade, which makes it particularly useful when digging trenches as are used, for example, in disposal of solid waste material.

After a trench is dug, the loose soil can be hauled or pushed to a storage site, whichever is easier. Objects to be buried can be pushed or carried into the trench. The increased height of the bucket 10 permits the track type loader vehicle to push much more refuse than is possible with a conventional bucket or dozer blade. The upper protective screen 76, being of expanded metal, does not materially curtail visibility. Large objects, such as refrigerators, stoves, tree trunks, and the like, can be segregated and loaded onto the bucket and carried, as illustrated in FIG. 3 and dumped in a truck or other vehicle for hauling away. When it is desired to cover the trench, the loose soil can be hauled orpushed back to the trench area and the covering operation completed, all with the use of the single bucket.

The present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The presently disclosed embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
