  • Patent number: 5794370
    Abstract: A new Tiered Trenching Backhoe Apparatus for creating a dual tiered trench which allows one service utility to be elevated above another service utility thereby preventing contact of the two service utilities resulting in increased safety. The inventive device includes a syncline plate with an interior angle of approximately 140 degrees, a first and second triangular coupler welded at one end to the syncline plate removably coupling to a pair of existing tooth shanks of a backhoe bucket, a first and second fluke welded to the syncline plate opposite of the triangular couplers, a first and second trihedral support members welded to the interior portion of syncline plate providing support, and a pair of replaceable teeth removably secured to the first and second flukes.

  • Patent number: 5743030
    Abstract: A loader such as a front end loader is provided with dam shell type bucket having a blade section, and collecting section pivoted thereon. The collecting section has a separating section having a separating surface curved on an are centered on pivotal axis of the collecting section and positioned relative to the leading edge of the blade section so that it tends to wipe clean the separating surface as it passes thereby when the relevant bucket sections are relatively pivoted from a screening position to a closed position. When the clam shell is in the screening position, the separating section forms at least a portion of the bottom of the bucket. A sifting screen for sifting finer material may also be provided as a dam at the free end of the collecting section.

  • Patent number: 5701693
    Abstract: A berm clearing attachment for removable securement to a road clearing vehicle, such as a bulldozer, road grader, hi-lift, dump truck, tractor, or skid-steer loader, for side or lateral dozing accumulated dirt and debris off of roads and road berms and away from guiderails by reciprocating laterally with respect to the longitudinal axis of the road clearing vehicle as the vehicle travels on the road and road berm. The berm clearing attachment includes a support framework removably securable to the front of the road clearing vehicle, and when used with the skid loader, the support framework would be removably securable to the front mounting plate of the loader.

  • Patent number: 5497569
    Abstract: A groomer attachment for forklift vehicles includes an elongated rigid member having a top and a bottom. A pair of spaced-apart fork receiving pockets are connected to the rigid member. A flexible blade extends from the bottom of the rigid member. Preferably the rigid member has a front and a rear. The attachment then has a pair of spaced-apart flexible blades extending from the bottom of the rigid member, a first blade being adjacent the front thereof and a second blade being adjacent the rear thereof. The rigid member may be channel-shaped.

  • Patent number: 5486085
    Abstract: A vehicle having an earth moving blade equipped with log gripping devices at the ends thereof. The log gripping devices consist of a mounting assembly which is attached to the rear of the earth moving blade. Mounted on the assembly is an arm which in its retracted position is located behind and within the area between the ends of the blade. Hydraulic pistons and cylinders move the arms outwardly of the ends of the blade independently to permit the arms to grip logs and felled trees between the arms and the ends of the blade.

  • Patent number: 5433032
    Abstract: An apparatus for removing a predetermined amount of contaminated overburdened soil. The apparatus comprises a container adapted to move along the soil. It is advanced forward and controlled by a backhoe or other crane configuration. A blade is attached at the front end of the container to cut a predetermined layer of overburdened soil. Vertical plates are included to cut the edge of the soil at the outer ends of the blades and confine the soil within the container. An air control device is also provided for controlling the flow of airborne particulates resulting from the cutting operation.

  • Patent number: 5377766
    Abstract: An angled blade unit is attached to a loader bucket and, as the bucket is moved along a roadway, the blade unit plows excess roadstone away from a newly poured concrete gutter in order to prepare a roadbed for paving. A gage rides along the flag of the gutter and limits the depth to which the blade unit plows into the roadstone.
