Abstract
Abstract Tailgate operation on a stack-forming implement is responsive to the reciprocable press of the implement by virtue of extensible linkage interconnecting the tailgate and actuating mechanism for the press. Because of the extensibility of the linkage, the press may be reciprocated without operating the tailgate while the tailgate is locked in a closed condition and the linkage is extended and retracted by the mechanism in lost motion fashion. A special spring arrangement connected with the tailgate serves the dual functions of initiating movement of the tailgate away from its closed position and cushioning the tailgate as it gravitates beyond its initially opened condition.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
107 words
A stacker including: a container adapted to receive a crop to be stacked; apparatus including a reciprocable compressor associated with the container for periodically compacting the crop into a stack conforming substantially in size and shape with the container, said container having an open end through which the stack passes during unloadiNg; a gate movable on said container into and out of closing relationship to said end; means releasably holding the gate in said closing relationship; and structure operably coupling said gate with said apparatus and shiftable during each actuation of the latter, said structure controlling movement of the gate only when said holding means is released.
Claim 2
Dependent Claim
107 words
A stacker including: a container adapted to receive a crop to be stacked; apparatus including a reciprocable compressor associated with the container for periodically compacting the crop into a stack conforming substantially in size and shape with the container, said container having an open end through which the stack passes during unloadiNg; a gate movable on said container into and out of closing relationship to said end; means releasably holding the gate in said closing relationship; and structure operably coupling said gate with said apparatus and shiftable during each actuation of the latter, said structure controlling movement of the gate only when said holding means is released.
Claim 3
Dependent Claim
20 words
A stacker as claimed in claim 1, wherein said structure pulls on said gate during said movement of the latter.
Claim 4
Dependent Claim
12 words
A stacker as claimed in claim 1, wherein said structure is extensible.
Claim 5
Dependent Claim
17 words
A stacker as claimed in claim 3, wherein said structure is provided with means limiting its extension.
Claim 6
Dependent Claim
31 words
A stacker as claimed in claim 1, wherein said gate is provided with means automatically initiating movement of the gate out of said closing relationship when said holding means is released.
Claim 7
Dependent Claim
31 words
A stacker as claimed in claim 5, wherein said initiating means is operable to retard further movement of said gate out of said relationship after said initial movement of the gate.
Claim 8
Dependent Claim
34 words
A stacker as claimed in claim 1, wherein said apparatus includes drive mechanism for said compressor, said structure being connected at one end to said mechanism and at the opposite end to said gate.
Claim 9
Dependent Claim
12 words
A stacker as claimed in claim 7, wherein said structure is extensible.
Claim 10
Dependent Claim
17 words
A stacker as claimed in claim 8, wherein said structure is provided with means limiting extension thereof.
Claim 11
Dependent Claim
100 words
A stacker including: a container adapted to receive a crop to be stacked; a reciprocable compressor associated with the container for periodically compacting the crop into a stack conforming substantially in size and shape with the container, said container having an open end through which the stack passes during unloading; mechanism for actuating the compressor; a gate movable on said container into and out of closing relationship to said end; means releasably holding the gate in said closing relationship; and structure linking said mechanism with the gate for controlling said movement of the gate when said holding means is released.
Claim 12
Dependent Claim
100 words
A stacker including: a container adapted to receive a crop to be stacked; a reciprocable compressor associated with the container for periodically compacting the crop into a stack conforming substantially in size and shape with the container, said container having an open end through which the stack passes during unloading; mechanism for actuating the compressor; a gate movable on said container into and out of closing relationship to said end; means releasably holding the gate in said closing relationship; and structure linking said mechanism with the gate for controlling said movement of the gate when said holding means is released.
Claim 13
Dependent Claim
28 words
A stacker as claimed in claim 10, wherein said mechanism includes a member swingable on said container, said structure being extensible for operation during swinging of the member.
Claim 14
Dependent Claim
17 words
A stacker as claimed in claim 11, wherein said structure is provided with means limiting its extension.
Claim 15
Dependent Claim
61 words
A stacker as claimed in claim 10, wherein said mechanism includes a pair of motion transmitting beams mounted on said container for swinging about spaced axes and interconnnected for swinging in opposite directions with respect to one another, said structure being extensible and being connected at one end to one of said members and at the opposite end to said gate.
Claim 16
Dependent Claim
17 words
A stacker as claimed in claim 13, wherein said structure is provided with means limiting its extension.
Claim 17
Dependent Claim
41 words
A stacker as claimed in claim 14, wherein said gate is swingable on the container and said structure lowers the gate to a position serving as a ramp when the compressor is moved to one end of its path of travel.
Claim 18
Dependent Claim
33 words
A stacker as claimed in claim 15, wherein said structure includes a pair of interconnected links shiftable relatively when the gate is locked in a closed position and when said compressor is reciprocated.
Claim 19
Dependent Claim
28 words
A stacker as claimed in claim 16; and means cushioning the extension of said links when the gate is unlocked and commences its movement toward said ramp position.
Claim 20
Dependent Claim
110 words
In a farm implement having a body provided with a pair of sides and a normally locked, upstanding endgate swingable outwardly and downwardly toward the ground, reciprocable structure carried by the body, and a swingable mechanism on each side respectively of the body for reciprocating said structure, a gate control comprising: a pair of links pivotally connecting the gate and each mechanism respectively, each pair of links being extensible, permitting reciprocation of said structure while the gate is locked without affecting the gate, each pair of links having stop means for limiting the extensibility thereof whereby, when the gate is unlocked, reciprocation of said structure raises and lowers the gate.
Claim 21
Dependent Claim
110 words
