Abstract
Abstract An automatic bale wagon having a bale pickup, an accumulator table, and a load table arranged on a mobile frame. A layer of bales is formed on the accumulator table which is successively pivotable to a generally vertical position to deliver successive layers to the load table. The load table is pivotable to a generally vertical position wherein a pair of pusher members on the frame are actuated to push a stack of bales off the load table onto the ground. Means are provided for selectively actuating the pusher members in response to sequential pivoting of the load table and the accumulator table to their respective vertical positions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
In a bale wagon having a mobile frame, an accumulator table pivotally mounted on said frame for accumulating a layer of bales when in a first generally horizontal position and being pivotable upwardly to a second generally vertical position for delivering said layer of bales, a load table pivotally mounted on said frame for receiving layers of bales delivered by said accumulator table to form a stack of bales thereon and being pivotable to a generally vertical position for depositing a stack of bales onto the ground, wherein the improvement comprises: pusher means mounted on said frame for removing a stack of bales from said load table when in its generally vertical position; and means for actuating said pusher means in response to sequentially pivoting said load table to its vertical position and said accumulator table to its second position.
Claim 2
Dependent Claim
140 words
In a bale wagon having a mobile frame, an accumulator table pivotally mounted on said frame for accumulating a layer of bales when in a first generally horizontal position and being pivotable upwardly to a second generally vertical position for delivering said layer of bales, a load table pivotally mounted on said frame for receiving layers of bales delivered by said accumulator table to form a stack of bales thereon and being pivotable to a generally vertical position for depositing a stack of bales onto the ground, wherein the improvement comprises: pusher means mounted on said frame for removing a stack of bales from said load table when in its generally vertical position; and means for actuating said pusher means in response to sequentially pivoting said load table to its vertical position and said accumulator table to its second position.
Claim 3
Dependent Claim
34 words
The subject matter of claim 1, wherein said pusher means includes at least one pusher member slidably mounted on said frame for rearward movement to remove the stack of bales from said load table.
Claim 4
Dependent Claim
30 words
The subject matter of claim 2, including spring means for moving said pusher member forwardly to a retracted position in response to pivoting said accumulator table to its first position.
Claim 5
Dependent Claim
61 words
The subject matter of claim 1, wherein said means for actuating said pusher means includes latch means operative in response to movement of said load table from its generally vertical position to release said accumulator table for independent movement, whereby said accumulator table may be successively actuated to deliver layers of bales to said load table without actuating said pusher means.
Claim 6
Dependent Claim
174 words
In a bale wagon having a mobile frame, an accumulator table pivotally mounted on said frame for accumulating a layer of bales when in a first generally horizontal position and being pivotable upwardly to a second generally vertical position for delivering said layer of bales, a load table pivotally mounted on said frame for receiving layers of bales delivered by said accumulator table to form a stack of bales thereon and being pivotable to a generally vertical position for depositing a stack of bales onto the ground, wherein the improvement comprises: a pusher member slidably mounted on said frame for movement between a retracted position and an extended position for removing a stack of bales from said load table; linkage means interconnecting said accumulator table and said pusher member for moving said pusher member to its extended position in response to movement of said accumulator table to its second position; and spring means for returning said pusher member to its retracted position in response to movement of said accumulator table to its first position.
Claim 7
Dependent Claim
174 words
In a bale wagon having a mobile frame, an accumulator table pivotally mounted on said frame for accumulating a layer of bales when in a first generally horizontal position and being pivotable upwardly to a second generally vertical position for delivering said layer of bales, a load table pivotally mounted on said frame for receiving layers of bales delivered by said accumulator table to form a stack of bales thereon and being pivotable to a generally vertical position for depositing a stack of bales onto the ground, wherein the improvement comprises: a pusher member slidably mounted on said frame for movement between a retracted position and an extended position for removing a stack of bales from said load table; linkage means interconnecting said accumulator table and said pusher member for moving said pusher member to its extended position in response to movement of said accumulator table to its second position; and spring means for returning said pusher member to its retracted position in response to movement of said accumulator table to its first position.
Claim 8
Dependent Claim
57 words
The subject matter of claim 5, wherein said linkage means includes latch means operative in response to movement of said load table from its generally vertical position to release said accumulator table for independent movement, whereby said accumulator table may be successively actuated to deliver layers of bales to said load table without actuating said pusher means.
Claim 9
Dependent Claim
98 words
The subject matter of claim 5, wherein said linkage means includes a flexible cable having one end connected to said pusher member and the other end connected to said frame, a first pulley mounted on said frame, a second pulley mounted on said frame, and a third pulley releasably mounted on said accumulator table, said cable being disposed successively over said first pulley, under said second pulley, and over said third pulley, whereby said cable is pulled upwardly by said third pulley to move said pusher member to its extended position in response to raising said accumulator table.
