Abstract
Abstract A rear universally supported gang plow mounting attachment is operatively connected to a forward horizontal transverse main header beam by a front to rear extending diagonal beam having its forward end pivotally anchored to one end of the header beam for angular displacement about a vertical axis, the gang plow mounting attachment being universally coupled to the rear end of the diagonal beam. An adjustable length longitudinal beam is pivotally attached at its forward end to the other end portion of the main transverse header beam and pivotally anchored at its rear end to the diagonal beam centrally intermediate the opposite ends thereof by structure operative to adjustably shift the axis of relative angular displacement of the diagonal beam and longitudinal beam longitudinally of the diagonal beam. The main header beam is further inclusive of structure for pivotally anchoring the mounting beam of a forward gang plow thereto for angular displacement about an axis generally paralleling the header beam.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
351 words
A gang plow hitch for at least one pair of multiple bottom gang plows of the type including forward transverse mounting beams, said plow hitch including a longitudinal beam having front and rear ends, said front end being adapted for universal connection to a draft vehicle, the rear end of said longitudinal beam including a horizontal transverse header beam supported therefrom for angular displacement about a horizontal axis transverse to said longitudinal beam and generally paralleling said header beam, one end of said transverse header beam projecting outwardly to one side of said longitudinal beam and including longitudinally spaced anchor means for pivotally attaching the forward transverse mounting beam of a forward gang plow thereto for angular displacement about a first axis paralleling said transverse header beam, a main horizontal diagonal beam pivotally anchored at its forward end to said one end of said header beam and inclined toward its rear end outwardly beyond the other side of said longitudinal beam, an elongated horizontal adjustable length adjustment beam, anchor means pivotally anchoring one end of said adjustment beam relative to said header beam for angular displacement relative thereto about an upstanding axis spaced intermediate the opposite ends of said header beam, attaching means attaching the other end of said adjustment beam to said diagonal beam for adjustment therealong to maintain said adjustment beam in position substantially paralleling the direction of intended movement of said hitch throughout limited angular adjustment of said diagonal beam relative to said header beam, an elongated longitudinal short couple beam, means universally coupling the forward end of said short couple beam to said rear end of said diagonal beam, and the rear end of said short couple beam including mounting means for rigidly mounting the forward transverse mounting beam of a rear gang plow to said short couple beam rear end, said diagonal beam being of a length in relation to the angulation thereof relative to said header beam to properly laterally space the forward and rear gang plows operatively associated therewith said rear gang plow projecting laterally outwardly of the other side of said longitudinal beam.
Claim 2
Dependent Claim
351 words
A gang plow hitch for at least one pair of multiple bottom gang plows of the type including forward transverse mounting beams, said plow hitch including a longitudinal beam having front and rear ends, said front end being adapted for universal connection to a draft vehicle, the rear end of said longitudinal beam including a horizontal transverse header beam supported therefrom for angular displacement about a horizontal axis transverse to said longitudinal beam and generally paralleling said header beam, one end of said transverse header beam projecting outwardly to one side of said longitudinal beam and including longitudinally spaced anchor means for pivotally attaching the forward transverse mounting beam of a forward gang plow thereto for angular displacement about a first axis paralleling said transverse header beam, a main horizontal diagonal beam pivotally anchored at its forward end to said one end of said header beam and inclined toward its rear end outwardly beyond the other side of said longitudinal beam, an elongated horizontal adjustable length adjustment beam, anchor means pivotally anchoring one end of said adjustment beam relative to said header beam for angular displacement relative thereto about an upstanding axis spaced intermediate the opposite ends of said header beam, attaching means attaching the other end of said adjustment beam to said diagonal beam for adjustment therealong to maintain said adjustment beam in position substantially paralleling the direction of intended movement of said hitch throughout limited angular adjustment of said diagonal beam relative to said header beam, an elongated longitudinal short couple beam, means universally coupling the forward end of said short couple beam to said rear end of said diagonal beam, and the rear end of said short couple beam including mounting means for rigidly mounting the forward transverse mounting beam of a rear gang plow to said short couple beam rear end, said diagonal beam being of a length in relation to the angulation thereof relative to said header beam to properly laterally space the forward and rear gang plows operatively associated therewith said rear gang plow projecting laterally outwardly of the other side of said longitudinal beam.
Claim 3
Dependent Claim
60 words
The combination of claim 1 wherein said anchor means including a horizontally disposed rearwardly opening V-shaped frame whose apex portion projects rearwardly of said head beam, the forward end of said V-shaped frame being rigidly anchored relative to said header beam, the forward end of said adjustment beam being pivotally anchored to the rear apex portion of said V-shaped frame.
Claim 4
Dependent Claim
48 words
The combination of claim 1 wherein said mounting means includes a pair of rearwardly divergent opposite side mounting arms carried by the rear portion of said short couple beam and to whose rear ends the forward transverse mounting beam of said rear gang plow may be rigidly anchored.
Claim 5
Dependent Claim
18 words
The combination of claim 3 including means for variably adjusting the included angle defined by said mounting arms.
Claim 6
Dependent Claim
46 words
The combination of claim 1 including a transversely extending jockey bar carried by a rear portion of said diagonal beam and having a free end portion, said free end portion including means adapted for securement to the rear end of said forward multiple bottom gang plow.
