"The main valve controls admission, release, and compression; the other (valve) regulates the cut—off only, which may be changed without in any way affecting the other events of the stroke. This cut—off valve may be placed in a separate valve chest, or it may be placed in the back of the main valve." —Derr, 1911

"Of all the contrivances for regulating the motion of machinery, this is said to be the most effectual. It will be readily understood by the following description. It consists of two heavy iron balls b, attached to the extremities of the two rods, b, e. These rods play on a joint at e, passing through a mortice in the vertical stem d, d. At f, these pieces are united, by joints to two short rods, f, h, which, at their upper ends, are again connected by joints at h, to a ring which slides upon the vertical stem d d." —Comstock, 1850

"The click barrel-ratchet R is set upon another larger ratchet-wheel, with its teeth pointing the opposite way, and its click rT is set in the clock-frame. That ratchet is connected with the great wheel by a spring ss' pressing against the two pins s in the ratchet and s' in the wheel. When you wind up the weight, the click Tr prevents the ratchet from turning back or to the right; and as the spring ss' is kept by the weight in a state of tension equivalent to the weight itself it will drive the wheel to the left for a short distance, when its end s is held fast, with the same force as if that end was pulled forward by the weight; and as the great wheel has to move very little during the short time the clock is winding, the spring will keep the clock going long enough." — Encyclopedia Britanica, 1893
