John Fowler - Plough Patent 

From Patents for Inventions; Abridgments (1884)

A.D. 1852, October 21.—No. 480.
FOWLER, JOHN—“Machinery for draining land.”
Title Page of Patent Abridgments Book

[p.37] The invention relates to machinery for forming drains in land by steam power and consists in so arranging the parts that “the boiler, steam-engine, and coulter or cutter are all combined and go together, the steam-engine giving motion to a drum to wind on a wire rope, and thus to move itself up to an anchor or fixed point on the land.” The machine is furnished with an upright coulter and a shoe or share for [p.38] forming the drain and drawing a continuous series of drain tiles into it, like the apparatus described in Nos. 12,989, A.D. 1850, and 13,285, A.D. 1850. A steam-engine and boiler are fixed upon the carriage, which travels on four broad wheels, and carries at its front end a large drum. On the crank shaft driven from the steam cylinder are four eccentrics, and these, by suitable connecting rods acting on a ratchet wheel on the drum shaft, impart a “step-by-step” motion thereto. The end of a wire rope is conducted from the drum to the opposite side of the field, passed round a pulley attached to an anchor or holdfast, and then brought back and fastened to the frame of the carriage; so that on the drum being put in motion by the engine, it winds up the rope, and draws the machine towards the anchor. If greater speed be required, the pulley is dispensed with, and the end of the rope is secured to the anchor. When the machine has arrived at the anchor, the power of the engine is applied to turn a small drum, round which is passed a rope from an anchor situated at the place where the machine is to recommence its action; and as the carriage is thus drawn back to the opposite side of the field, the large drum pays out or delivers its rope in readiness for the next forward movement of the machine. The patentee states that for some purposes he prefers to perform the operation of delivering or paying out the rope from the large drum by turning the front wheels by any convenient gearing worked by the engine, so that the bite of such wheels upon the land shall act to drive the machine in the requisite direction. This arrangement also serves for the transport of the machine from place to place along common roads.

Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath. (1882) -- Nathaniel Egleston, who was writing then about deforestation, but speaks equally well about the danger of climate change today.
Carl Sagan Thumbnail Carl Sagan: In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) ...(more by Sagan)

Albert Einstein: I used to wonder how it comes about that the electron is negative. Negative-positive—these are perfectly symmetric in physics. There is no reason whatever to prefer one to the other. Then why is the electron negative? I thought about this for a long time and at last all I could think was “It won the fight!” ...(more by Einstein)

Richard Feynman: It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly. ...(more by Feynman)
