"The self-acting slide-rest carries reduction by driving the lathe itself the small "feed" movement necessary for bringing the tool to bear on successive portions of the work, it dispenses wholly with the need for physical exertion on the part of the workman, and does not even demand his continuous supervision." —The Encyclopedia Britannica, 1903

"Place a bit of tinder in the cavity of the piston of the 'fire-syringe'. Put the piston into the open end of the cylinder and force it in, compressing the confined air as abruptly as possible. Promptly remove the piston. The tinder will probably be on fire." — Avery, 1895

An illustration of a lever safety valve. "Suppose the valve A is just suppose to open when the steam pressure under it is 120 lb. per square inch, that mean area of the valve exposed to steam pressure is 4 square inches, the weight of the valve 4ln., the distance C D being 3 inches the centre of gravity of the lever 7 inches from D, and its weight 6 lb.; where must the weight E - which is 50 lb. - be placed on the lever? The total upward force on the valve is 120 × 4 - 4 = 476 lb., and the moment of this force about D is 476 × 3 = 1428. This is the only negative moment, all other forces tending to turn the lever the opposite way." -New, 1891
