Abstract
Abstract An elongated support beam, arranged for connection at its front end to a pulling tractor and supported at its rear end by a vertically adjustable carrier wheel, pivotally mounts a framework carrying a pair of plow gangs. The gangs are disposed on a line disposed obliquely to the support beam and extending rearward of the carrier wheel and are rotatable with the framework to position each gang selectively in its ground working position. A pair of tail wheels, one associated with each gang, is mounted detachably at the trailing end of the gangs for rotation therewith. Additional plow bottoms may be added to the trailing end of the gangs by detaching the pair of tail wheels and attaching the latter to the trailing end of the added plow bottoms. Means may be provided for rendering the carrier wheels steerable in response to turning of the tractor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
A two-way gang plow, comprising a. an elongated support, b. means on the front end of the support for securing the same to a pulling vehicle, c. a single carrier wheel on the rear end of the support mounted for vertical adjustment relative to the support, d. a plow framework, e. means mounting the framework on the support for rotation on an axis substantially parallel to the longitudinal axis of the support, f. a plurality of spaced pairs of plow bottoms mounted on the framework on a line disposed obliquely to the longitudinal axis of the support and outwardly of the carrier wheel, the framework and the plow bottoms extending forward and rearward of the carrier wheel, one plow bottom of each pair forming one gang and the other plow bottom of each pair forming a second gang, g. tail wheel means, and h. means mounting the tail wheel means on the trailing end of the framework for association with each of said gangs in the ground working position of the latter.
Claim 2
Dependent Claim
172 words
A two-way gang plow, comprising a. an elongated support, b. means on the front end of the support for securing the same to a pulling vehicle, c. a single carrier wheel on the rear end of the support mounted for vertical adjustment relative to the support, d. a plow framework, e. means mounting the framework on the support for rotation on an axis substantially parallel to the longitudinal axis of the support, f. a plurality of spaced pairs of plow bottoms mounted on the framework on a line disposed obliquely to the longitudinal axis of the support and outwardly of the carrier wheel, the framework and the plow bottoms extending forward and rearward of the carrier wheel, one plow bottom of each pair forming one gang and the other plow bottom of each pair forming a second gang, g. tail wheel means, and h. means mounting the tail wheel means on the trailing end of the framework for association with each of said gangs in the ground working position of the latter.
Claim 3
Dependent Claim
40 words
The two-way gang plow of claim 1 wherein the framework includes at least two separate sections each mounting at least one pair of plow bottoms and each trailing section being secured to the trailing end of the next leading section.
Claim 4
Dependent Claim
34 words
The two-way gang plow of claim 1 wherein the tail wheel means is mounted on the trailing end of the framework and disposed rearward of and in alignment with the trailing plow bottom pair.
Claim 5
Dependent Claim
25 words
The two-way gang plow of claim 1 wherein the tail wheel means comprises a pair of tail wheels mounted for association one with each gang.
Claim 6
Dependent Claim
29 words
The two-way gang plow of claim 1 wherein the framework mounting means comprises a shaft mounted on the support for rotation on an axis substantially parallel to the support.
Claim 7
Dependent Claim
57 words
The two-way gang plow of claim 1 including vertical pivot means mounting the carrier wheel on the support, and link means connected at one end to the vertical pivot means and arranged for connection at the opposite end to a pulling vehicle for effecting turning of the carrier wheel means in response to turning of the vehicle.
Claim 8
Dependent Claim
38 words
The two-way gang plow of claim 1 including a carrier wheel support arm mounted on the rear end of the support for pivotal movement on a substantially horizontal axis, and means mounting the carrier wheel on the arm.
Claim 9
Dependent Claim
128 words
The two-way gang plow of claim 1 including a. a carrier wheel support arm mounted on the rear end of the support for pivotal movement on a substantially horizontal axis, b. vertical pivot means mounting the carrier wheel on the arm, c. steering bracket means mounted on the support for pivotal movement on a vertical axis, D. first link means, e. pivot means connecting one end of the first link means to the vertical pivot means, f. universal pivot means connecting the opposite end of the first link means to the steering bracket means on the pivot axis of the arm, and g. second link means connected pivotahly at one end to the steering bracket means and arranged for connection at its opposite end to a pulling vehicle.
Claim 10
Dependent Claim
55 words
The two-way gang plow of claim 8 wherein the second link means is arranged for connection to a pulling vehicle to the side of the support opposite the pivot connections to the steering bracket means, whereby turning of the pulling vehicle in one direction effects turning of the steering wheel means in the opposite direction.
Claim 11
Dependent Claim
29 words
The two-way gang plow of claim 1 including power means interengaging the support and framework for rotating the latter selectively between the ground working positions of the two gangs.
