Abstract
Abstract A self-loading and unloading wagon for transporting bales of hay or straw which consists essentially of a rotatably mounted drum having helically arranged internal partitions which define at least one continuous helical bale-receiving channel extending from one end of the drum to the other. The drum can be associated with automatic bale-loading and bale-discharging means and can also be used for handling and mixing dry feed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A self-loading and unloading bale wagon comprising a wheeled chassis, an elongated drum transversely and rotatably mounted on said chassis, a T-shaped partition projecting inwardly from the inside of said drum and extending helically from one end of said drum to the other end thereof, the cross arm of the T-shaped partition along with the inside surface of the said drum and adjacent flights of the helically arranged partition defining a continuous helical box-like bale-receiving channel within said drum extending from one end thereof to the other, said channel having a bale inlet at one end thereof and a bale outlet at the other end thereof, means for rotating said drum, and means within said channels to prevent bales from reversing their direction of movement within said channel as said drum is rotated.
Claim 2
Dependent Claim
133 words
A self-loading and unloading bale wagon comprising a wheeled chassis, an elongated drum transversely and rotatably mounted on said chassis, a T-shaped partition projecting inwardly from the inside of said drum and extending helically from one end of said drum to the other end thereof, the cross arm of the T-shaped partition along with the inside surface of the said drum and adjacent flights of the helically arranged partition defining a continuous helical box-like bale-receiving channel within said drum extending from one end thereof to the other, said channel having a bale inlet at one end thereof and a bale outlet at the other end thereof, means for rotating said drum, and means within said channels to prevent bales from reversing their direction of movement within said channel as said drum is rotated.
