Abstract
Abstract An elongated tension member having at least one elastic section. One end of the tension member is anchored to the center coupling pole of a four-wheel farm wagon and the other end of the tension member is connected to the outer end of the steering arm carried by one of the spindle assemblies of the front wheels of the wagon in order to apply a pull on the one steering arm to a first side of the wagon while applying a pull in the opposite direction on the rear end of the coupling pole. Further, a pull in the first direction is also applied to the forward end portion of the associated wagon tongue to which the tie rod for the front wheels of the wagon is secured and thus a thrust in the first direction is applied to the rear end of the towing vehicle to which the forward end of the wagon tongue is secured.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
213 words
In combination with a four-wheel trailer chassis provided with dirigible front wheel spindles and a steering assembly including steering arm portions carried by said spindles and transverse tie rod means secured and extending between said arm portions with a forwardly projecting towing tongue including a rear end portion pivotally secured to the trailer chassis for oscillation about an upstanding axis and means connecting said tongue to said tie rod means for reciprocation of the latter in response to oscillation of the towing tongue, an anti-sway attachment including an elongated tension member provided with at least one tensioned elastic section, first means anchoring one end of said tension member to said chassis at a point adjacent the centerline thereof and second means anchoring the other end of said tension member to a portion of said steering assembly adjacent one of said spindles whereby said tension member will exert a constant force on said steering assembly to turn said spindles in one direction, said trailer chassis including a longitudinal center coupling pole extending between the opposite end portions of the wagon chassis, said first means comprising a link chain section encircled about the forward end portion of said coupling pole and having said one end of said tension member anchored to said link chain section.
Claim 2
Dependent Claim
213 words
In combination with a four-wheel trailer chassis provided with dirigible front wheel spindles and a steering assembly including steering arm portions carried by said spindles and transverse tie rod means secured and extending between said arm portions with a forwardly projecting towing tongue including a rear end portion pivotally secured to the trailer chassis for oscillation about an upstanding axis and means connecting said tongue to said tie rod means for reciprocation of the latter in response to oscillation of the towing tongue, an anti-sway attachment including an elongated tension member provided with at least one tensioned elastic section, first means anchoring one end of said tension member to said chassis at a point adjacent the centerline thereof and second means anchoring the other end of said tension member to a portion of said steering assembly adjacent one of said spindles whereby said tension member will exert a constant force on said steering assembly to turn said spindles in one direction, said trailer chassis including a longitudinal center coupling pole extending between the opposite end portions of the wagon chassis, said first means comprising a link chain section encircled about the forward end portion of said coupling pole and having said one end of said tension member anchored to said link chain section.
Claim 3
Dependent Claim
58 words
The combination of claim 1 wherein said second means comprIses an elongated anchor plate having one end secured to one of said steering arm portions at the point of connection of the corresponding end of the tie rod means therewith and the other end of said anchor plate has said other end of said tension member anchored thereto.
Claim 4
Dependent Claim
48 words
The combination of claim 2 wherein said anchor plate includes a keyhole opening on one end thereof, said steering assembly including an upstanding fastener secured through one of said steering arm portions and the corresponding end of said tie rod means, said fastener passing through said keyhole opening.
Claim 5
Dependent Claim
12 words
The combination of claim 3 wherein said anchor plate is substantially planar.
Claim 6
Dependent Claim
28 words
The combination of claim 3 wherein the opposite end portions of said anchor plate are relatively offset and joined by an inclined center portion of said anchor plate.
Claim 7
Dependent Claim
196 words
In combination with a vehicle chassis provided with dirigible front wheel spindles and a steering assembly including steering arm portions carried by said spindles and transverse tie rod means secured and extending between said arm portions with a forwardly projecting towing tongue including a rear end portion pivotally secured to the trailer chassis for oscillation about an upstanding axis and means connecting said tongue to said tie rod means for reciprocation of the latter in response to oscillation of the towing tongue, anti-sway means including an elongated tension member provided with at least one tensioned elastic section, first means anchoring one end of said tension member to said chassis at a point adjacent the centerline thereof and the second means anchoring the other end of said tension member to a portion of said steering assembly adjacent one of said spindles whereby said tension member will exert a constant force on said steering assembly to turn said spindles in one direction, said vehicle chassis including a longitudinal member, said first means comprising a flexible member encircled about said longitudinal chassis member adjacent the forward end thereof and having said one end of said tension member anchored thereto.
Claim 8
Dependent Claim
196 words
In combination with a vehicle chassis provided with dirigible front wheel spindles and a steering assembly including steering arm portions carried by said spindles and transverse tie rod means secured and extending between said arm portions with a forwardly projecting towing tongue including a rear end portion pivotally secured to the trailer chassis for oscillation about an upstanding axis and means connecting said tongue to said tie rod means for reciprocation of the latter in response to oscillation of the towing tongue, anti-sway means including an elongated tension member provided with at least one tensioned elastic section, first means anchoring one end of said tension member to said chassis at a point adjacent the centerline thereof and the second means anchoring the other end of said tension member to a portion of said steering assembly adjacent one of said spindles whereby said tension member will exert a constant force on said steering assembly to turn said spindles in one direction, said vehicle chassis including a longitudinal member, said first means comprising a flexible member encircled about said longitudinal chassis member adjacent the forward end thereof and having said one end of said tension member anchored thereto.
