An anvil is a basic tool, in the simplest terms it is a block with a hard surface on which another object is struck. The inertia of the anvil allows the energy of the striking tool to be transferred to the work piece.

"The blocks, which are technically known as voussoirs, should be of a wedge shape, the center or top block being the keystone A; the lower blocks B B which rest on the supporting pier are the springers, the upper surface of which is called the skewback, C C; the side blocks, as D, are termed the hauches. The lower surface or soffit of the arch is the intrados, E, and the upper surface the entrados, F. The rise of the arch is the distance from the springing to the soffit, G, the width between the springers is called the span, H, and the radius I. The triangular spaces between the arches are termed spandrils, K." — The Encyclopedia Britannica, 1910

"A Block is a pulley or a system of pulleys rotating on a pintle mounted in its frame or shell with its band and strap. There are many kinds of blocks, as a pulley block, a fiddle block, a fish block, a fly block, a heart block, a hook block, etc. A block and tackle is the block and the rope rove through it, for hoisting or obtaining a purchase."—(Charles Leonard-Stuart, 1911)

"Combinations of pulleys are made in great variety. In the forms most commonly used, one continuous cord passes around all the pulleys. Frequently two or more sheaves are mounted in the same block and turn on the same axis, as in the common block and tackle." — Avery, 1895

"Mooring anchors are those which are places in harbours, for the convenience of vessels frequenting them. A large buoy is attached to the end of the mooring cable, and the ship is made fast to a ring-bolt fitted on the buoy. Mooring anchors are not limited by considerations of weight, as other anchors are, he only requirements being that they have sufficient holding power, and do not project above the ground, as any projection in the shallow waters in which they are usually placed would render ships liable to injury from grounding on them, and be dangerous to fishing-nets." — Encyclopedia Britanica, 1893

"A movable pulley is one whos block is movable. One end of the cord is fastened to the beam, and the weight is sspended from the pulley, the other end of the cord being drawn by the application of a force P. A little consideration will show that if P moves through a certain distance, say 1 foot, W will move through half that distance, or 6 inches; hence, a pull of 1 pound at P will life 2 pounds at W." — Hallock, 1905

"Raise the rifle with both hands high enough to clear the line of vision, barrel downward, point of the bayonet to the left front. When necessary to raise the rifle well above the head, it may be supported between the thumb and forefinger of the left hand. This position will be necessary against attacks from higher elevation, such as men mounted or on top of parapets." — Moss, 1914
