Apparatus for laying out and taking up a long length, wide width flexible sheeting
First Claim
1. An apparatus for use in conjunction with a powered vehicle to lay out and take up a long length, wide width flexible sheeting material comprising in combination:
- a framework adapted for mounting engagement on a powered vehicle such as to be carried over a ground surface by the vehicle, the framework having a transversely positioned framework arm extending outwardly at each end thereof;
pivot means attaching each arm to the framework;
means associated with each of the framework arms for journal-mounting a shaft between them;
an arbor assembly including a cylindrical mandrel having each of its ends journalled to a framework arm so as to be rotatable about a longitudinal axis, said mandrel adapted for carrying a long length, wide width flexible sheeting material thereon in a wrapped and layered orientation about its surface extent;
means rotating the arms about the pivot means to a lowered position for loading and unloading the mandrel and to a raised position for rotating the mandrel; and
a hydraulic system to power and control the rotation for wrapping flexible sheeting material onto the mandrel and in an opposite direction of rotation for unwrapping sheeting material from the mandrel;
the wrapping and unwrapping of the flexible sheeting material being accomplished as the powered vehicle is moved to travel over a ground surface area;
the hydraulic system comprising;
a hydraulically operated motor mounted on at least one end of the arbor assembly and having a drive shaft engageable with the mandrel, a means to provide hydraulic fluid pressure, a reservoir to provide a source of hydraulic fluid, a hydraulic valve control means to switch hydraulic fluid pressure from the means providing said pressure to the motor driving the mandrel and to return the hydraulic fluid to the reservoir, and a hydraulic fluid circuit comprising a pair of hydraulic fluid pressure lines interconnecting the control means with the motor driving the mandrel, a hydraulic fluid pressure line interconnecting the control means with the means providing the hydraulic fluid pressure, a hydraulic fluid line interconnecting the control means with the reservoir, and a hydraulic fluid line interconnecting the reservoir with the means providing the hydraulic fluid pressure.

Abstract
This invention provides an apparatus for use on and carried by a powered vehicle for laying out and taking up a long length, wide width flexible sheeting material as may be used to cover a sanitary landfill site, the apparatus having a framework adapted for mounting engagement on the vehicle and characterized by a pair of transversely extending arms which carry a journalled arbor assembly between them. The arbor assembly is powered for rotational motion and is controlled by an operator in a manner to either load a flexible sheeting material onto a mandrel of the arbor assembly or off-load flexible sheeting material from the mandrel as the vehicle travels over a ground surface area.

9. An apparatus for use in conjunction with a powered dozer type vehicle to lay out and take up a long length, wide width flexible sheeting material comprising in combination:
-
a wide width framework having means which extends rearwardly therefrom for mounting engagement onto a dozer blade of the vehicle and having a transversely positioned framework arm extending outwardly and forwardly at each end thereof; means associated with each said arm for journal-mounting a shaft between them; an arbor assembly including a long length mandrel having each of its end journalled to a framework arm so as to be rotatable about a longitudinal axis of the mandrel, said mandrel adapted for carrying a long length, wide width flexible sheeting material thereon in a wrapped and layered orientation about its surface extent; and a hydraulic power and control system for effecting rotation of the mandrel in a first direction of rotation for wrapping flexible sheeting material onto the mandrel and in an opposite direction of rotation for unwrapping sheeting material from the mandrel; the wrapping and unwrapping of the flexible sheeting material being accomplished as the powered vehicle is moved to travel over a ground surface area; each of the transversely positioned framework arms being affixed to the framework via a pin providing rotation of the arm about a pin axis, each said arm being positionable by a double-acting hydraulic cylinder having hydraulic fluid pressure supply and return lines connected into the control system such that the arms may be hydraulically lowered for mounting of the arbor assembly onto the arms and raised in a position for operation of the mandrel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

19. An apparatus for use in conjunction with a powered vehicle to alternately deposit and remove a surface cover of long length, wide width flexible sheeting material, the apparatus comprising:
-
a vertical truss member having one of its sides adapted for mounting on a powered vehicle capable of traveling backward and forward over a surface to be covered with or uncovered from the surface cover; said truss member extending transversely of the direction of travel of the vehicle when in use; a mandrel support arm extending outwardly from the side of the truss member facing away from the support vehicle at each end of the truss member for rotatably supporting each end of the mandrel carrying a roll of surface cover material, the mandrel support arms being moveable between a mandrel loading/unloading position and a mandrel rotating position, each mandrel support arm having a locking mechanism for rotatably securing an end of a mandrel to the outwardly extending end of the support arm; a mandrel removably mounted on the mandrel support arms for rotation about a longitudinal axis, said mandrel being spaced a sufficient distance from the truss member to provide clearance between the truss member and the periphery of a full roll of surface cover material so that the roll will rotate freely in either desired direction; power means to cause rotation of the mandrel; and control means to regulate the direction of rotation and speed of rotation of the mandrel in relation to the direction of travel of the vehicle so that the cover material can be alternately unwrapped from the mandrel or rewrapped onto the mandrel as the vehicle moves in one direction or another over a surface to be covered or uncovered. - View Dependent Claims (20, 21)
