Abstract
Abstract Hay is fed from a stack to a point of further processing or livestock consumption by intermittent advancement of the stack to positions beneath a cutting mechanism that is carried by a vertically swingable boom. The boom is carried at one end thereof opposite to the cutting mechanism by a mast and is actuated by a fluid pressure piston and cylinder assembly. A lateral conveyor beneath the boom and adjacent the leading end of the stack receives the hay that is cutaway, and a flipper on the cutting mechanism deflects the cutaway hay toward the conveyor.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
203 words
A machine for unloading a stack of feed-stuff comprising: a mast; an elongated boom extending from said mast toward a stack to be unloaded; means intermediate the top and bottom levels of the stack mounting the boom on said mast for swinging movement about a horizontal axis; power means coupled with said boom for swinging the same; a cutting mechanism carried by the boom remote from the mast for swinging movement with the boom through a path of travel concentric with said axis; a support for said stack provided with means for advancing the stack toward the mast into said path of travel of said mechanism; and an elongated, lateral conveyor between the mast and one end of said advancing means, and underlying said boom for receiving the feedstuff cut from the stack by the mechanism and carrying the same away to a point of further processing or livestock consumption, said mechanism being provided with an elongated sickle bar having a series of cutting elements therealong and mounted for horizontal reciprocation traversing said path of travel, said boom having a driven member extending therealong and swingable thErewith for reciprocating said bar, said mast having a drive extending upwardly therealong for actuating said member.
Claim 2
Dependent Claim
203 words
A machine for unloading a stack of feed-stuff comprising: a mast; an elongated boom extending from said mast toward a stack to be unloaded; means intermediate the top and bottom levels of the stack mounting the boom on said mast for swinging movement about a horizontal axis; power means coupled with said boom for swinging the same; a cutting mechanism carried by the boom remote from the mast for swinging movement with the boom through a path of travel concentric with said axis; a support for said stack provided with means for advancing the stack toward the mast into said path of travel of said mechanism; and an elongated, lateral conveyor between the mast and one end of said advancing means, and underlying said boom for receiving the feedstuff cut from the stack by the mechanism and carrying the same away to a point of further processing or livestock consumption, said mechanism being provided with an elongated sickle bar having a series of cutting elements therealong and mounted for horizontal reciprocation traversing said path of travel, said boom having a driven member extending therealong and swingable thErewith for reciprocating said bar, said mast having a drive extending upwardly therealong for actuating said member.
Claim 3
Dependent Claim
19 words
A machine as claimed in claim 1 wherein said power means is disposed between the mast and said conveyor.
Claim 4
Dependent Claim
53 words
A machine as claimed in claim 2 wherein said power means is adapted to pull the boom downwardly to move said mechanism through the stack and to push the boom upwardly to place said mechanism in position for receiving the stack beneath the mechanism as the stack is advanced by said advancing means.
Claim 5
Dependent Claim
46 words
A machine as claimed in claim 1 wherein said mechanism extends along one longitudinal edge of the conveyor above the latter and below the level of the proximal end of said advancing means when the mechanism is at the lowermost end of its path of travel.
Claim 6
Dependent Claim
31 words
A machine as claimed in claim 1 wherein is provided a jackshaft extending from the mast to the conveyor for actuating the latter, said shaft being operably connected with said drive.
Claim 7
Dependent Claim
58 words
A machine as claimed in claim 1 wherein is provided a flipper beneath the boom, extending along said bar, and mounted on said mechanism for swinging movement above a horizontal axis for deflecting the feedstuff toward the conveyor as the same is cut from the stack by said mechanism; and means operably coupling said member with said flipper.
Claim 8
Dependent Claim
197 words
A machine for unloading a stack of feedstuff comprising: a stack support having a discharge end and provided with means for advancing a stack toward said end until a portion of the stack overhangs said end; a lateral conveyor across said end of the support and lower than the latter in position to underlie the overhanging portion of the stack; a mast spaced from said end of the support beyond said conveyor in the direction of stack advancement; an elongated boom extending from said mast, toward the stack, and crossing above the conveyor; means intermediate the top and bottom levels of the stack mounting the boom on the mast for swinging movement about a horizontal axis disposed beyond said conveyor in the direction of stack advancement; a cutting mechanism carried by the boom remote from the mast in disposition to overlie said overhanging stack portion; and extensible power means located between said conveyor and the mast and coupled with said boom for swinging the boom toward and away from the conveyor to cut the overhanging portion from the stack and onto the conveyor for carrying the cutaway portion to a point of further processing on livestock consumption.
Claim 9
Dependent Claim
197 words
A machine for unloading a stack of feedstuff comprising: a stack support having a discharge end and provided with means for advancing a stack toward said end until a portion of the stack overhangs said end; a lateral conveyor across said end of the support and lower than the latter in position to underlie the overhanging portion of the stack; a mast spaced from said end of the support beyond said conveyor in the direction of stack advancement; an elongated boom extending from said mast, toward the stack, and crossing above the conveyor; means intermediate the top and bottom levels of the stack mounting the boom on the mast for swinging movement about a horizontal axis disposed beyond said conveyor in the direction of stack advancement; a cutting mechanism carried by the boom remote from the mast in disposition to overlie said overhanging stack portion; and extensible power means located between said conveyor and the mast and coupled with said boom for swinging the boom toward and away from the conveyor to cut the overhanging portion from the stack and onto the conveyor for carrying the cutaway portion to a point of further processing on livestock consumption.
Claim 10
Dependent Claim
47 words
A machine as claimed in claim 7, wherein said power means is operable to cause the leading extremity of said mechanism to pass downwardly beyond said end of the support as the mechanism approaches its lower limit of travel to shear the overhanging portion from the stack.
Claim 11
Dependent Claim
24 words
A machine as claimed in claim 8, wherein said conveyor is provided with a platform for the overhanging portion to facilitate said shearing action.
Claim 12
Dependent Claim
36 words
A machine as claimed in claim 8 wherein said mechanism is positioned to swing inwardly of said end of the support above the latter and then outwardly of said end at the level of the latter.
Claim 13
Dependent Claim
32 words
A machine as claimed in claim 7, wherein said mechanism is provided with means for deflecting the feedstuff toward the conveyor as the same is cut from the stack by said mechanism.
Claim 14
Dependent Claim
30 words
A machine as claimed in claim 11, wherein said conveyor is provided with second deflector means in opposition to said first-mentioned deflector means for augmenting the action of the latter.
