A tilting mechanism incorporated into a conventional load carrying device including a bucket portion, a pair of elongated handles supporting the bucket portion, and a front wheel. The tilting mechanism includes a frame adapted to being secured to a rearwardly extending location of the elongated handles and such that the bucket portion is disposed between the frame and the front wheel. Elongated supports are incorporated into the frame and, in combination with the front wheel, support the wheelbarrow upon a surface. The frame includes structure for establishing an angle or incline, relative to an uneven or peaked surface, and is actuated to facilitate tilting of the bucket portion about a longitudinal axis extending through the load carrying device.

I claim: 1. A tilting mechanism incorporated into a conventional load carrying device, the device including a bucket portion, a pair of elongated handles supporting the bucket portion, and a front wheel, said tilting mechanism comprising: a frame secured to locations of the elongated handles and such that the bucket portion is disposed between said frame and the front wheel; said frame further comprising first and second support ends which, in combination with the front wheel, supports the device upon a surface; and a pivoting mechanism incorporated into said frame and including a pivot point positioned approximate said support ends and a distance below the bucket, said frame being actuated to facilitate tilting of the bucket portion about a longitudinal axis along said pivot point extending through the front wheel and to arrange the bucket portion in a level fashion relative to the surface. 2. The tilting mechanism as described in claim 1, said frame further comprising a base plate from which extend supports for mounting said frame to underside locations of the elongated handles. 3. The tilting mechanism as described in claim 2, said frame further comprising a pair of elongated brackets extending rearwardly from said base plate, a crosswise bracket extending proximate an upper edge location of said base plate. 4. The tilting mechanism as described in claim 3, further comprising an arcuate and fixedly positioned extending member having first and second downwardly directed ends, a cross beam securing opposite sides of said arcuate extending member, said elongated brackets extending rearwardly from said base plate being arranged in rotative fashion relative to maid fixedly positioned arcuate member. 5. The tilting mechanism as described in claim 4, further comprising an arcuate shaped gear plate secured to said cross beam, a rotational beating interconnecting said cross beam and gear plate with said base plate. 6. The tilting mechanism as described in claim 5, said gear plate further exhibiting a plurality of spaced apart serrations along a lower arcuate edge thereof, a slot formed through said base plate in proximity to said serrations and a spring-loaded projection extending through said slot and engaging a selected serration to define a specified tilt of the bucket portion relative to the pound surface. 7. The tilting mechanism as described in claim 6, further comprising an elongated handle pivotally secured to said spring-loaded projection via a support tab extending from a surface of the base plate. 8. A tilting mechanism incorporated into a conventional load carrying device, the device including a bucket portion, a pair of elongated handles supporting the bucket portion, and a front wheel, said tilting mechanism comprising: a frame secured to locations of the elongated handles and such that the bucket portion is disposed between said frame and the front wheel; said frame further comprising an elongated and crosswise extending ground support member exhibiting first and second downwardly angled ground support ends which, in combination with the front wheel, supports the device upon a surface; and a pivoting mechanism incorporated into said frame and which is actuated to facilitate tilting of the bucket portion about a longitudinal axis extending through the front wheel and to arrange the bucket portion in a level fashion relative to the surface. 9. The tilting mechanism as described in claim 8, said frame further comprising a bracket secured to a central location of the crosswise extending ground support member, a "V" shaped support including first and second upwardly extending arms securing to locations along the handles, a central pivoting interconnection being established between said "V" support and said bracket. 10. The tilting mechanism as described in claim 9, further comprising a secondary support member extending in crosswise fashion and securing at locations to said "V" shaped support arms, extending ends of said secondary support member engaging additional locations associated with the load carrying device arms. 11. The tilting mechanism as described in claim 10, further comprising an arcuate plate portion incorporated into a crosswise extending surface of said bracket portion, a plurality of arcuately spaced apart and perimeter extending apertures being defined in said plate portion. 12. The tilting mechanism as described in claim 11, further comprising a linearly displaceable handle having a first gripping end secured in proximity to an extending handle end, a second projecting end seating through a support aperture defined in said secondary support member and, upon rotating the bucket about a centerline extending through the front wheel, aligning and seating through a selected one of said apertures defined in said arcuate plate portion. 13. A tilting mechanism incorporated into a conventional load carrying device, the device including a bucket portion, a pair of elongated handles supporting the bucket portion, and a front wheel, said tilting mechanism comprising: a frame secured to locations of the elongated handles and such that the bucket portion is disposed between said frame and the front wheel, said frame further comprising an elongated and crosswise extending ground support member exhibiting first and second downwardly angled ground support ends which, in combination with the front wheel, supports the device upon a surface; a "V" shaped support including first and second upwardly extending arms secured to locations along the handles, a central pivoting interconnection being established between said "V" support and a bracket secured to said crosswise extending ground support member; and a pivoting mechanism incorporated into said frame and which is actuated to facilitate tilting of the bucket portion about a longitudinal axis extending through the central pivoting interconnection and the front wheel and to arrange the bucket portion in a level fashion relative to the surface. 14. The tilting mechanism as described in claim 13, further comprising a secondary support member extending in crosswise fashion and securing at locations to said "V" shaped support arms, extending ends of said secondary support member engaging additional locations associated with the load carrying device arms. 15. The tilting mechanism as described in claim 14, further comprising an arcuate plate portion incorporated into a crosswise extending surface of said bracket portion, a plurality of arcuately spaced apart and perimeter extending apertures being defined in said plate portion. 16. The tilting mechanism as described in claim 15, further comprising a linearly displaceable handle having a first gripping end secured in proximity to an extending handle end, a second projecting end seating through a support aperture defined in said secondary support member and, upon rotating the bucket about a centerline extending through the front wheel, aligning and seating through a selected one of said apertures defined in said arcuate plate portion. 17. A tilting mechanism incorporated into a load carrying device including a bucket, a pair of elongate extending handles, and a front wheel, said tilting mechanism comprising: a frame comprising supports which, in combination with the wheel, support the bucket upon a surface; and said frame further comprising a pivot point located at a height approximate said supports and a distance below the bucket and elongate extending handles, the bucket being tilted about a longitudinal axis extending between and below the elongated handles of the wheelbarrow and through its front wheel and said pivot point.
