Abstract
Abstract In the stacking of hay or other crops, a windrow or swath is lifted off the ground, fed into a pile collected by a vehiclesupported, stack forming body and the pile compressed from time to time in the body, all in a continuous operation as the vehicle is advanced across the field, by virtue of the provision of an accumulator which receives the crop while the pile is being compressed, and from which accumulator the crop so accumulated is thereupon dumped onto the compressed pile by retraction of a shiftable section of the press roof.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
138 words
In a stacking machine: a hollow, open top stack forming body having a pair of side walls provided with upward extensions at one of their ends; a vertically reciprocable, open bottom press carried by the body and provided with side walls within the body disposed along said side walls of the latter and between said extensions, said press having a roof between its side walls; and a continuous feeder for directing a crop into the body between said side walls of the press below the roof when the press is up, and for directing the crop between the extensions above the roof while the press is being lowered, said roof having a section retractable to a position while the press is being raised for discharging into the body the crop accumulating thereon while the press is being lowered.
Claim 2
Dependent Claim
138 words
In a stacking machine: a hollow, open top stack forming body having a pair of side walls provided with upward extensions at one of their ends; a vertically reciprocable, open bottom press carried by the body and provided with side walls within the body disposed along said side walls of the latter and between said extensions, said press having a roof between its side walls; and a continuous feeder for directing a crop into the body between said side walls of the press below the roof when the press is up, and for directing the crop between the extensions above the roof while the press is being lowered, said roof having a section retractable to a position while the press is being raised for discharging into the body the crop accumulating thereon while the press is being lowered.
Claim 3
Dependent Claim
47 words
In a stacking machine as claimed in claim 1; and a backstop interconnecting the press and the extensions and movable to a position during lowering of the press for limiting the crop emanating from the feeder to movement onto said section while the press is being lowered.
Claim 4
Dependent Claim
19 words
In a stacking machine as claimed in claim 2 wherein said backstop is collapsible as the press is raised.
Claim 5
Dependent Claim
25 words
A stacking machine as claimed in claim 1 wherein said extensions are shiftable vertically to a lowered position alongside said side walls of the body.
Claim 6
Dependent Claim
16 words
A stacking machine as claimed in claim 4; and releasable means for holding said extensions elevated.
Claim 7
Dependent Claim
18 words
A stacking machine as claimed in claim 4, said press having means for raising and lowering said extensions.
Claim 8
Dependent Claim
25 words
A stacking machine as claimed in claim 1; and a top wall joining said extensions for downward deflection of the crop emanating from said feeder.
Claim 9
Dependent Claim
32 words
A stacking machine as claimed in claim 7 wherein said extensions and said top wall are shiftable vertically to a lowered position disposing the extensions alongside said side walls of the body.
Claim 10
Dependent Claim
21 words
A stacking machine as claimed in claim 8; and releasable latch means for holding the extensions and the top wall elevated.
Claim 11
Dependent Claim
40 words
A stacking machine as claimed in claim 9, said top wall being carried by the side walls of the press upon release of said latch means, rendering the press operable to raise and lower the extensions and the top wall.
Claim 12
Dependent Claim
101 words
In a stacking machine: a crop feeder; a hollow, open, top stack forming body for receiving the crop from said feeder; a vertically reciprocable, open bottom press carried by the body and provided with a roof for compacting the crop received by said body; and a hollow structure carried by the body for accumulating the crop emanating from the feeder during compaction, said roof having a section shiftable to one position forming a bottom for said structure disposed to receive the crop from the feeder during compaction, and to another position for discharging the accumulated crop into the body after compaction.
Claim 13
Dependent Claim
101 words
In a stacking machine: a crop feeder; a hollow, open, top stack forming body for receiving the crop from said feeder; a vertically reciprocable, open bottom press carried by the body and provided with a roof for compacting the crop received by said body; and a hollow structure carried by the body for accumulating the crop emanating from the feeder during compaction, said roof having a section shiftable to one position forming a bottom for said structure disposed to receive the crop from the feeder during compaction, and to another position for discharging the accumulated crop into the body after compaction.
Claim 14
Dependent Claim
69 words
A stacking machine as claimed in claim 11 wherein said body, said press and said structure are each provided with a pair of spaced side walls, the side walls of the press being reciprocable between the side walls of the body and between the side walls of said structure, the side walls of said structure normally extending upwardly beyond the corresponding side walls of the body adjacent said feeder.
Claim 15
Dependent Claim
45 words
A stacking machine as claimed in claim 12 wherein said roof has a rear section rigidly joining the side walls of the press, and wherein said shiftable section overlies the rear section when the shiftable section is in said position for discharging the accumulated crop.
Claim 16
Dependent Claim
39 words
A stacking machine as claimed in claim 11 wherein said press is provided with a pair of spaced side walls each having an elongated, longitudinally extending track, said shiftable section being carried by said tracks for horizontal reciprocation therealong.
Claim 17
Dependent Claim
36 words
A stacking machine as claimed in claim 14 wherein said roof has a rear section rigidly joining the side walls of the press, and wherein is provided means interconnecting the sections for reciprocating the shiftable section.
Claim 18
Dependent Claim
34 words
A stacking machine as claimed in claim 11 wherein said press is provided with a pair of spaced side walls and wherein is provided means connected with said side walls for reciprocating the press.
Claim 19
Dependent Claim
29 words
A stacking machine as claimed in claim 11, said structure having a backstop disposed to limit the extent of movement of the crop emanating from the feeder during compaction.
Claim 20
Dependent Claim
25 words
A stacking machine as claimed in claim 17 wherein said backstop is extensible during descent of the press and contractible during ascent of the press.
Claim 21
Dependent Claim
106 words
A stacking machine as claimed in claim 18 wherein said press and said structure are each provided with a pair of sidewalls, each side wall of the press having an elongated, longitudinally extending track, said shiftable section being carried by said tracks for horizontal reciprocation therealong, said backstop having one end thereof pivotally connected with said tracks and the opposite end thereof pivotally connected with said side walls of said structure. 20 A stacking machine as claimed in claim 19 wherein said backstop comprises a plurality of panels interposed between said pivotal connections thereof and including an intermediate panel slidable relative to the panels proximal thereto.
Claim 22
Dependent Claim
52 words
A stacking machine as claimed in claim 20 wherein said roof has a rear section rigidly joining the side walls of the press, wherein said side walls of said structure have a top wall rigidly interconnecting the same, and wherein said backstop is interposed between said rear section and said top wall.
Claim 23
Dependent Claim
43 words
A stacking machine as claimed in claim 21 wherein the backstop is disposed horizontally above the side walls of said structure when the backstop is contracted and disposed on an incline between the side walls of said structure when the backstop is extended.
