Wright's patent "is designed as an improvement in that class of equalizing-arrangements in which the two horses of the team are connected with the short arm of a bar, or equivalent vibrating-device coupled to the plow-beam, and the single horse is hitched to the opposite arm or side of such device, at such point as will enable the single horse to exert as much power to keep himself abreast in the line as it is exerted conjointly by the two."
