Chain separator for padding machine
First Claim
1. A padding apparatus for padding underground cable or pipeline by continuously separating excavated material piled alongside an excavated ditch into relatively fine padding material and relatively rough residual material as the apparatus moves forward and placing the relatively fine padding material in the ditch, the apparatus comprising:
- a frame for supporting and moving an endless openwork in an endless path for lifting excavated material in an elevating direction, said endless openwork having rods and transverse chain sections attached to said rods, whereby said rods and chain sections define openings that allow relatively fine padding material to pass therethrough;
a discharge conveyor positioned to receive the relatively fine padding material and convey the padding material to the ditch for padding cable or pipeline therein.

Abstract
A padding apparatus for padding underground cable or pipeline is provided. The padding apparatus is adapted to continuously separate excavated material piled alongside an excavated ditch into relatively fine padding material and relatively rough residual material as the apparatus moves forward. The padding apparatus continuously places the relatively fine padding material in the ditch. According to the invention, the apparatus includes a frame for supporting and moving an endless openwork in an endless path for lifting excavated material in an elevating direction. The endless openwork has rods and transverse chain sections attached to the rods, whereby the rods and chain sections define openings that allow relatively fine padding material to pass therethrough. A discharge conveyor is positioned beneath at least a portion of the endless openwork of the separator to receive the relatively fine padding material and convey the padding material to the ditch for padding cable or pipeline therein.

14. A padding machine for attachment to a sub-frame of 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 the one side of the ditch and processing the excavated material into padding material for placement in the ditch, the padding machine comprising:
- a frame;
coupler for releasably connecting said frame to the sub-frame of the prime mover whereby the sub-frame can raise and lower the padding machine to control the amount of excavated material processed by the padding machine;
an endless openwork mounted to said frame for moving in an endless path, said endless openwork having rods and transverse chain sections attached to said rods, whereby said rods and chain sections define openings that allow padding material to pass therethrough, said endless openwork lifting excavated material and separating the lifted excavated material into padding material and rough material by passing padding material through said openwork; and
a discharge conveyor mounted to said frame whereby it receives padding material passed through said endless openwork and transports the padding material for placement in the ditch. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
