EXTENDIBLE CONVEYOR SYSTEM
First Claim
1. An extendible conveyor system, for a transport vehicle such as a truck having a bed, delivering material from one level to another higher level, comprising:
- at least one conveyor having a main section and an extension section axially nesting within said main section, said extension section having an end opposite said main section, said extension section telescoping in and out of said main section;
means for providing power to said at least one conveyor for telescoping movement of said extension section from said main section;
a continuous flexible member travelling upon and through said main section and said extension section, said continuous flexible member being driven by one of chain drive or rollers;
a conveyor stem connecting to said main section in a cantilever manner, said conveyor stem including an outer portion and an internal core, said outer portion having an axle for pivotal connection to said main section, said internal core extending axially from said outer portion;
means for providing power to said at least one conveyor for sliding and telescoping movement of said extension section from said main section;
two hydraulic rams moving said providing power for vertical movement of said outer portion relative to said inner core of said conveyor stem;
at least one gear plate securing to said inner core and one of a hydraulic motor or a chain driven motor providing power to said at least one gear plate, wherein said at least one gear plate and one of a hydraulic motor or chain drive motor cooperate to rotate said inner core through 360 degrees; and
,wherein said system rotates about the plane of the truck bed, raises above the plane of the truck bed, and lengthens axially to deliver material from the truck bed to a higher level as selected by the user.

Abstract
A conveyor system includes an extension section that slides inwardly and telescopes outwardly of a main section of conveyor. The extension motion is powered by at least one hydraulic ram. The conveyor has a stem that lowers to a loadable height by the retraction of double hydraulic rams upon a steel internal core. The conveyor then lifts vertically in a cantilevered manner upon a vertical ram and then rotates 360 degrees parallel to the plane of a truck bed using a cooperating gear plate and a hydraulic motor with a chain. Paddles push material secured to a chain drive or alternately a belt and the chain drive or belt moves through a series of sprockets or rollers in a continuous manner. The paddles eventually return to their initial location.

-
at least one conveyor having a main section and an extension section axially nesting within said main section, said extension section having an end opposite said main section, said extension section telescoping in and out of said main section; means for providing power to said at least one conveyor for telescoping movement of said extension section from said main section; a continuous flexible member travelling upon and through said main section and said extension section, said continuous flexible member being driven by one of chain drive or rollers; a conveyor stem connecting to said main section in a cantilever manner, said conveyor stem including an outer portion and an internal core, said outer portion having an axle for pivotal connection to said main section, said internal core extending axially from said outer portion; means for providing power to said at least one conveyor for sliding and telescoping movement of said extension section from said main section; two hydraulic rams moving said providing power for vertical movement of said outer portion relative to said inner core of said conveyor stem; at least one gear plate securing to said inner core and one of a hydraulic motor or a chain driven motor providing power to said at least one gear plate, wherein said at least one gear plate and one of a hydraulic motor or chain drive motor cooperate to rotate said inner core through 360 degrees; and
,wherein said system rotates about the plane of the truck bed, raises above the plane of the truck bed, and lengthens axially to deliver material from the truck bed to a higher level as selected by the user. - View Dependent Claims (2, 3, 4, 5)

6. An extendible conveyor system, for a transport vehicle such as a truck having a bed, delivering material from one level to another higher level, comprising:
-
at least one conveyor having a main section and an extension section axially nesting within said main section, said extension section having an end opposite said main section, said extension section telescoping in and out of said main section by an internally positioned hydraulic ram; a pair of chains spaced apart in mutually parallel planes, having a plurality of paddles spaced there across, said paddles pushing material placed upon said chains, and said pair of chains and said paddles passing within and upon said extension section and said main section; a conveyor stem connecting to said main section in a cantilever manner, said conveyor stem including an outer portion and an internal core, said outer portion having an axle for pivotal connection to said main section, said internal core extending axially from said outer portion; means for providing power to said at least one conveyor for sliding and telescoping movement of said extension section from said main section; two hydraulic rams moving said providing power for vertical movement of said outer portion relative to said inner core of said conveyor stem; at least one gear plate securing to said inner core and one of a hydraulic motor or a chain driven motor providing power to said at least one gear plate, wherein said at least one gear plate and one of a hydraulic motor or chain drive motor cooperate to rotate said inner core through 360 degrees; a plurality of controls operating said flexible member, telescoping of said extension member, rotation of said main section upon said conveyor stem, and elevation of said outer portion upon said internal core; wherein said controls lower said outer portion to a loadable height relative to the truck bed and raise said outer portion vertically once loading upon said flexible member has completed; wherein said controls rotate said main section to a suitable angle relative to said conveyor stem towards the elevation of the higher level; wherein said controls lengthen said system such that said extension section telescopes outwardly from said main section at the angle of said main section to reach the higher level; wherein said controls move said flexible member thus delivering material loaded thereon to the higher level; and
,wherein said system rotates about the plane of the truck bed, raises above the plane of the truck bed, and lengthens axially to deliver material from the truck bed to a higher level as selected by the user.
