Compact padding machine
First Claim
1. A self-contained padding apparatus for moving along one side of a pipeline ditch, picking up excavated material from said one side of the ditch, and processing the excavated material into padding material for placement in the ditch, said apparatus comprising in combination:
- a prime mover; and
a padding attachment comprising means removably connecting said padding attachment to one end of said prime mover whereby said attachment moves along the path of travel of said prime mover;
means for collecting and separating excavated material from the side of the ditch as said prime mover moves along the side of the ditch into padding material and residual material;
means from transporting the padding material to the ditch; and
side members supported by said padding attachment and positioned on opposite sides of said means for collecting and separating to retain the excavated material on said means for collecting and separating, wherein at least one of said side members has an opening through which the means for transporting the padding material extends from said padding attachment whereby padding material may be transported through said side members to the pipeline ditch.

Abstract
A padding machine attachment for a vehicle is provided. When padding of a ditch for a pipeline or cable is required, the padding machine is removably attached in a position at one end of a conventional bucket loader, bulldozer, or other base machine or vehicle, whereby said attachment moves along the path of travel of the vehicle. As the vehicle moves the padding machine attachment along one side of the pipeline ditch, the padding machine attachment picks up at least a portion of a pile of excavated material placed parallel to and along the same side of the ditch and processes the excavated material into padding material for placement into the ditch for padding the pipeline or cable.

3. A self-contained padding attachment for attachment to a prime mover for moving with the prime mover along one side of a ditch to pick up at least a portion of a pile of excavated material placed parallel to and along said one side of the ditch and processing the excavated material into padding material for placement in the ditch, the padding attachment comprising:
-
a frame comprising a pair of side frame members connected by cross members; a coupler releasably connecting said frame to the prime mover whereby the prime mover can raise and lower the padding attachment; a screen movable in an endless path mounted to said frame, said screen collecting and lifting excavated material and separating the lifted excavated material into padding material and residual material by permitting only suitable padding material to pass through said screen as the padding attachment moves along said one side of the ditch; and a discharge conveyor that is impervious to padding material and that is mounted to said frame whereby it receives padding material passed through said screen and transports the padding material for placement in the ditch. - View Dependent Claims (4, 5, 6, 7, 8)
