1. A modified scraper machine for distributing padding material within a previously dug ditch, comprising:
- a prime mover, a distributing section including a container for holding padding material, a conveyor means for transferring material from said container into a ditch;
means, including said prime mover, for propelling said container along the surface of the ground, such that the conveyor means can follow a path of travel which is parallel to a previously dug ditch;
said container means having a bottom, opposed side walls, a movable rear wall, and a movable front wall;
said side walls being affixed to and upwardly extending from said bottom, said movable rear wall including means by which it can be moved horizontally towards said front wall, said front wall including means by which it can be moved vertically respective to said bottom and side walls, thereby forming an outlet of controllable area therebetween;
said bottom, opposed side walls, movable rear wall, and movable front wall form an upwardly opening container into which padding material can be charged in order to store padding material within said container means;
frame members having opposed ends by which said conveyor means is supported normally to the direction of travel of the machine, and in underlying relationship respective to said outlet such that padding material which may flow through said outlet is received by said conveyor means;
means by which said frame members are removably supported from said distributing section such that said conveyor means is disposed adjacent to said outlet in a position to receive padding material which may flow therethrough, and such that said conveyor means can be detached for transporting purposes;
so that padding material can be charged into said container, said front wall can be raised to form an outlet, said rear wall can be moved towards said front wall to force the material through said outlet, where it is received by said conveyor and transported into a ditch.

Abstract
A machine for distributing padding material within a previously dug ditch so that a pipe placed within the ditch is protected from objectionable objects which may otherwise cause damage thereto.
The padding machine comprises an earth moving vehicle having a laterally arranged conveyer means connected thereto, so that padding material can be transported laterally away from the vehicle and into a ditch while the machine travels along a parallel path respective to the ditch.

10. A transporting and distributing machine for padding pipe placed within a ditch, said machine comprising a modified scraper machine in the form of a ground supported vehicle having a container into which padding material can be placed;
- means for guidably propelling said vehicle along a path of travel which is parallel to the ditch;
said container having opposed sidewalls affixed to a floor, and a rear and a front wall; means mounted said rear wall respective to said sidewalls and floor such that said rear wall is movable towards said front wall to thereby force any material therebetween towards said front wall; means mounting said front wall in sealed relationship respective to said side walls and in a vertically movable manner respective to said floor to thereby form a variable outlet through which padding material can flow; a conveyor means, mount means by which said conveyor means is positioned in underlying relationship respective to said outlet, a marginal length of said conveyor extending laterally away from said machine;
said floor having a marginal edge portion which extends through said outlet and is superimposed over a marginal lateral edge portion of said conveyor;
a prime mover for imparting conveying motion into said conveyor;means controlling the relative position of said rear wall respective to said front wall, means controlling the relative position of said front wall respective to said floor, and means controlling the speed of said conveyor motion; said conveyor means comprising and endless belt having a roller disposed at each end thereof, means by which said belt is guidably received about said rollers;
means imparting rotational motion into said rollers to cause movement of said belt;spaced parallel frame members having opposed ends, means by which said rollers are journaled to said opposed ends of said frame members such that said frame members are disposed parallel to the path of travel of said endless belt; means by which said frame members are removably supported from said distributing section such that said endless belt is disposed adjacent to said outlet in a position to receive padding material which may flow therethrough, and such that said conveyor means can be detached for transporting purposes. - View Dependent Claims (11, 12, 13, 14, 15)
