  • Publication number: 20140138108
    Abstract: A scraper attachment for mobile vehicles is provided with a resiliently deformable blade. In one embodiment, the blade is formed from a portion of a vehicle tire. A mounting bracket allows the scraper attachment to be used on a wide range of bucket-style loaders. In various embodiments, a user engages and disengages a portion of a bucket, extending forwardly from the mobile vehicle, with open mounting jaws that extend rearwardly from the mounting bracket by moving the bucket loader forward and backward with respect to the scraper attachment. An optional securement leash may couple the mounting frame with the mobile vehicle.

    Abstract: An improved material handling bucket assembly for construction or agricultural front loading or backhoe applications is disclosed. Scraper and grader blades pivotally mounted relative to the bucket bottom cooperatively move to provide normal bucket operation, or scraping, or grading operations. A scraper blade selectively rotates between a first position closing an opening through the bottom wall of the bucket to a second position extending below the bucket for removing ground soil during a scraping operation and directing the removed soil into a collection chamber of the bucket. A single power source and linkage assembly controls movement of the scraper and grader blades, which also cooperatively move to change the size of the opening in the bottom wall during a scraping operation.

A mounting plate is secured at an end of the central support member. A resilient blade assembly is attached to the attachment hook-up assembly by means of a bearing bracket and bearing means. The resilient blade assembly includes an elongated blade mounting channel having a pair of resilient blades mounted thereon. The resilient blade assembly includes extension blades that may be mounted at the ends of the blade mounting channel in order to increase the effective width of the resilient blade assembly. The extension blades may be contoured to approximate different surfaces such as a roadside curb.

  • Patent number: 6088939
    Abstract: An implement adapter for providing excavation versatility that couples with and attaches to an excavation tool assembly for mounting a working implement thereon. The implement adapter comprises a frame for holding a working implement, wherein the frame is coupled and semi-fixedly attached to an excavation tool assembly. A parking projection holds the coupling element of the frame at a sufficient height above a surface when the implement adapter is detached from the excavation tool assembly and supported on the surface by the parking projection and a lowermost portion of either the frame or the working implement. The height at which the coupling portion is held by the parking projection enables engagement of the coupling portion with a cooperative coupling element on the excavation tool assembly without the need for any manual assistance.

  • Patent number: 6085447
    Abstract: A trenching tool for releasable attachment to a bucket of a front end loader includes a pair of support brackets with a chute-like blade thereon. Each bracket includes a support arm for the blade and an integral shoulder brace portion for mounting underneath a surface of the bucket. The front edge of the bucket is received within a notch of each support bracket and is clamped thereto by a releasable upper clamp. Each support bracket includes a bearing surface for transferring forces acting on the tool to the underside of the bucket to enhance the tool's stability during use. The chute-like blade enables sod to be rolled up into the blade for deposit into the bucket upon an initial pass of the loader. Upon subsequent passes, entrenching is accomplished with the loosened dirt entering the chute for deposit into the bucket of the front end loader.

  • Patent number: 6073371
    Abstract: A vehicle snowplow system with an adjustable-bias tripping mechanism. The system includes a snowplow blade or moldboard which is pivotally mounted to a frame, the latter being adapted for mounting to a vehicle. The moldboard "trips" or pivotally moves between a normal plowing position and a displaced position when a lower region of the moldboard contacts a rigid obstruction. The system includes at least one biasing assembly operable to bias the moldboard toward the normal position with a biasing force, the biasing assembly configured so as to provide an adjustment to the biasing force to compensate for variances in roadway or environmental conditions.
