Bale shape control means

Claim 2

Improved bale shape control means for a baler bale chamber within which bales are successively formed and moved toward a rear discharge end thereof, comprising: a top tension rail having front and rear portions articulately interconnected together; an elongated, generally straight bottom tension rail; and means on said bale chamber for effectuating disposition of said rear portion of said top rail in a position in which it is spaced above and substantially parallel to said bottom rail and disposition of said front portion of said top rail in a position in which it rearwardly declines toward said bottom rail.

Claim 3

Improved bale shape control means as recited in claim 1, wherein the articulate connection between said front and rear portions of said top rail is a pivot connection at their respective adjacent ends; and means is located at said respective adjacent, pivotally connected ends of said front and rear portions which constitutes a stop limiting pivotal movement of said front and rear portions relative to each other to only toward and away from one side of a generally horizontal plane which faces toward said bottom rail and extends through said pivotally connected ends.

Claim 4

Improved bale shape control means as recited in claim 3, wherein said means which constitules a stop includes: a member fixed on one of said front and rear portions of said top rail and projecting therefrom at said end thereof adjacent the end of said other one of said portions; and a part of said other one of said portions which overlies said member and will abut the same when said portions are pivoted relative to each other to form said generally horizontal plane.

Claim 5

In a baler including an elongated bale chamber having a bottom and within which bales are successively formed and moved toward a discharge end thereof, the improvement which comprises: a compound member forming a top for said bale chamber and including a front portion and a rear portion, said front portion having a forward end which is pivotally mounted on said baler and a rearward end which is pivotally connected to a forward end of said rear portion of said compound member; and means interconnecting said rear portion of said compound member with said bale chamber so as to dispose said rear portion in a position in which it is spaced above and substantially parallel to said bottom and dispose said front portion of said compound member in a position in which it rearwardly declines toward said bottom whereby a forward section is defined in said bale chamber remote from its discharge end and between said bottom thereof and said front portion of said compound member in which said bales are subjected to increasing compressive forces as the same are successively moved therethrough toward said discharge end, while a rear section is defined in said bale chamber extending from said front section to said discharge end thereof and between said bottom thereof and said rear portion of said compound member in which said bales are subjected to substantially uniform compressive forces as the same are successively moved therethrough toward said discharge end.

Claim 6

In a baler including an elongated bale chamber having a bottom and within which bales are successively formed and moved toward a discharge end thereof, the improvement which comprises: a compound member forming a top for said bale chamber and including a front portion and a rear portion, said front portion having a forward end which is pivotally mounted on said baler and a rearward end which is pivotally connected to a forward end of said rear portion of said compound member; and means interconnecting said rear portion of said compound member with said bale chamber so as to dispose said rear portion in a position in which it is spaced above and substantially parallel to said bottom and dispose said front portion of said compound member in a position in which it rearwardly declines toward said bottom whereby a forward section is defined in said bale chamber remote from its discharge end and between said bottom thereof and said front portion of said compound member in which said bales are subjected to increasing compressive forces as the same are successively moved therethrough toward said discharge end, while a rear section is defined in said bale chamber extending from said front section to said discharge end thereof and between said bottom thereof and said rear portion of said compound member in which said bales are subjected to substantially uniform compressive forces as the same are successively moved therethrough toward said discharge end.

Claim 7

In a baler including an elongated bale chamber within which bales are successively formed and moved toward a discharge end thereof, said chamber having a pair of laterally spaced, substantially parallel side members, upper and lower cross members located remote from said discharge end and respectively extending between and secured to the upper and lower edges of said side wall members and an elongated bottom wall member disposed generally between said lower edges of said side wall members and connected to said lower cross member, the improvement which comprises: a compound top wall member disposed generally between said upper edges of said side wall members and including a front portion and a rear portion, said front portion being pivotally connected at a forward end to said upper cross member and at a rearward end to a forward end of said rear portion; and means interconnecting said bottom wall member and said rear portion of said compound top wall member so as to dispose the same substantially parallel to each other with said front portion of said compound member declining rearwardly toward said bottom wall member, whereby a forward section is defined in said bale chamber remote from its discharge end and between said bottom wall member, said side wall members and said front portion of said compound top wall member in which said bales are subjected to increasing compressive forces as the same are successively moved therethrough toward said discharge end, while a rear section is defined in said bale chamber extending from said front section to said discharge end thereof and between said bottom wall member, said side wall members and said rear portion of said compound top wall member in which said bales are subjected to substantially uniform compressive forces as the same are successively moved therethrough toward said discharge end.

Claim 8

In a baler including an elongated bale chamber within which bales are successively formed and moved toward a discharge end thereof, said chamber having a pair of laterally spaced, substantially parallel side members, upper and lower cross members located remote from said discharge end and respectively extending between and secured to the upper and lower edges of said side wall members and an elongated bottom wall member disposed generally between said lower edges of said side wall members and connected to said lower cross member, the improvement which comprises: a compound top wall member disposed generally between said upper edges of said side wall members and including a front portion and a rear portion, said front portion being pivotally connected at a forward end to said upper cross member and at a rearward end to a forward end of said rear portion; and means interconnecting said bottom wall member and said rear portion of said compound top wall member so as to dispose the same substantially parallel to each other with said front portion of said compound member declining rearwardly toward said bottom wall member, whereby a forward section is defined in said bale chamber remote from its discharge end and between said bottom wall member, said side wall members and said front portion of said compound top wall member in which said bales are subjected to increasing compressive forces as the same are successively moved therethrough toward said discharge end, while a rear section is defined in said bale chamber extending from said front section to said discharge end thereof and between said bottom wall member, said side wall members and said rear portion of said compound top wall member in which said bales are subjected to substantially uniform compressive forces as the same are successively moved therethrough toward said discharge end.
