“ This turning of the crank-axle, so as to lift the plow, is accomplished by a friction band or brake, which is made to engage with an inner extension of the hub of one of the carrying wheels, so that, as the wheel moves forward, it causes the crank-axle to turn upward from a horizontal to a vertical position.'
The circuit court was of opinion that, if the state of the art was such as to entitle Davenport to a broad claim for any device by which the plow is lifted by the power of the team through a brake or friction clutch, the defendants' machine would infringe. ”

“ The defendants' machine is thus described in the opinion of the circuit court, and the description is conceded by the counsel for the plaintiff to be a fair one: 'The defendants' machine is a wheel or sulky plow, with a bent or cranked iron axle, upon which the plow-beams are pivoted at about two-thirds of the distance from the forward end to the coulter, so that the plow is nearly balanced upon the axle or crank, and the arrangement of the mechanism is such that, when the plow is running or operating in the ground, the crank part is in a horizontal position ”

“ The journal that carries the wheel that runs in the furrow is so formed that it may be removed from the back of the swing-axle and be secured to the front, so that the machine may run level when there is no furrow for the wheel to run in as is the case when preparing the ground for cotton seed.
'The swing-axle, G, is attached to the plow-frame by two iron hinges, H, H'; the one, H, on the side of the long beam forming an arm or lever, I, to which is attached a chain, J, which passes over a wheel, K, and is made fast to the plow-frame. The wheel, K, turns upon a stud in the end of a lever, L ”
