Ripper assembly

Claim 2

An improved ripper assembly comprising: A. an elongated pull bar; B. a pair of mutually spaced, elongated legs arranged in substantially spaced parallelism and extended orthogonally from said pull bar, each leg being characterized by a base end portion pivotally connected with an end portion of said pull bar and a distal end portion remotely related to the base end portion thereof; C. means for connecting a ripper shank to said legs including a beam extended between the distal end portions of the legs and rigidly connected thereto; D. first connecting means for connecting said pull bar with a first given tractor including a pair of rigid, elongated arms connected with said pull bar and extended therefrom in substantial parallelism with the legs of said pair; and E. second connecting means for connecting said pull bar with a second given tractor including a force transfer linkage connected with the pull bar and extended orthogonally therefrom in a direction substantially opposite to that in which said pair of arms is extended.

Claim 3

The ripper assembly of claim 1 wherein said force transfer linkage is an articulated linkage.

Claim 4

An improved ripper assembly for deepripping strata at substantial depths beneath the surface of a body of soil comprising: A. a draw bar of a substantially U-shaped configuration including a pair of pivotal legs, each of said legs being characterized by a base end and a distal end remotely related to the base end and further characterized by a length greater than the length of a given tractor, said legs being disposed in substantial parallelism and spaced apart a distance sufficient for receiving the given tractor therebetween, and means including a transversely oriented pull bar interconnecting said legs at the base ends thereof; B. means adapted to mount said draw bar on said given tractor with the pull bar disposed forwardly of the tractor and the distal ends of the legs disposed rearwardly thereof; C. an articulated force transfer linkage for coupling said draw bar with another tractor disposed forwardly of said pull bar, including a first link coupled at one end thereof to said other tractor and a second link pivotally connected with said first link and connected with said pull bar; and D. means including a support beam extended between the distal ends of said legs for supporting a ripper shank rearwardly of the given tractor.

Claim 5

An improved ripper assembly for deepripping strata at substantial depths beneath the surface of a body of soil comprising: A. a draw bar of a substantially U-shaped configuration including a pair of pivotal legs, each of said legs being characterized by a base end and a distal end remotely related to the base end and further characterized by a length greater than the length of a given tractor, said legs being disposed in substantial parallelism and spaced apart a distance sufficient for receiving the given tractor therebetween, and means including a transversely oriented pull bar interconnecting said legs at the base ends thereof; B. means adapted to mount said draw bar on said given tractor with the pull bar disposed forwardly of the tractor and the distal ends of the legs disposed rearwardly thereof; C. an articulated force transfer linkage for coupling said draw bar with another tractor disposed forwardly of said pull bar, including a first link coupled at one end thereof to said other tractor and a second link pivotally connected with said first link and connected with said pull bar; and D. means including a support beam extended between the distal ends of said legs for supporting a ripper shank rearwardly of the given tractor.

Claim 6

The assembly of claim 3 wherein said means for mounting said draw bar on said given tractor comprises a pair of rigid arms integrally connected with said pull bar and rearwardly extended therefrom, and means including a pair of laterally spaced trunnions for connecting said arms to said given tractor.

Claim 7

In combination with a first and a second tractor arranged in fore-and-aft alignment, an improved ripper assembly for deep-ripping strata at substantial depths beneath the surface of a body of soil comprising: A. a pull bar extended transversely between said first and second tractors, and a pair of laterally spaced legs, each leg being characterized by a base end pivotally connected with one end of said pull bar and a distal end disposed rearwardly of said first tractor; B. means for connecting said pull bar with said first tractor including a pair of laterally spaced arms integrally connected to said pull bar and extended rearwardly therefrom, and means including a pair of trunnions mounted on said first tractor, at opposite sides thereof, for receiving the extended arms in a coupled relationship; C. means for connecting said pull bar with said second tractor, including a first link integrally connected with the pull bar and extended forwardly therefrom, a second link pivotally coupled to said first link, and means for coupling said second link with said second tractor; D. means for mounting a ripper shank on said ripper assembly including a transversely oriented shank-supporting beam integrally connected with the distal ends of said legs, rearwardly of said first tractor; and E. means for raising and lowering said shank-supporting beam.

Claim 8

In combination with a first and a second tractor arranged in fore-and-aft alignment, an improved ripper assembly for deep-ripping strata at substantial depths beneath the surface of a body of soil comprising: A. a pull bar extended transversely between said first and second tractors, and a pair of laterally spaced legs, each leg being characterized by a base end pivotally connected with one end of said pull bar and a distal end disposed rearwardly of said first tractor; B. means for connecting said pull bar with said first tractor including a pair of laterally spaced arms integrally connected to said pull bar and extended rearwardly therefrom, and means including a pair of trunnions mounted on said first tractor, at opposite sides thereof, for receiving the extended arms in a coupled relationship; C. means for connecting said pull bar with said second tractor, including a first link integrally connected with the pull bar and extended forwardly therefrom, a second link pivotally coupled to said first link, and means for coupling said second link with said second tractor; D. means for mounting a ripper shank on said ripper assembly including a transversely oriented shank-supporting beam integrally connected with the distal ends of said legs, rearwardly of said first tractor; and E. means for raising and lowering said shank-supporting beam.
