Balance Shaft

In piston engine engineering, a balance shaft is an eccentric weighted shaft which offsets vibrations in engine designs that are not inherently balanced (for example, most four-cylinder engines). They were first invented and patented by British engineer Frederick Lanchester in 1904.

Famous quotes containing the words balance and/or shaft:

    At last I feel the equal of my parents. Knowing you are going to have a child is like extending yourself in the world, setting up a tent and saying “Here I am, I am important.” Now that I’m going to have a child it’s like the balance is even. My hand is as rich as theirs, maybe for the first time. I am no longer just a child.
    —Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)

    Lord, crack their teeth! Lord, crush these lions’ jaws!
    So let them sink as water in the sand;
    When deadly bow their aiming fury draws,
    Shiver the shaft ere past the shooter’s hand.
    So make them melt as the dishoused snail
    —Bible: Hebrew Psalm LVIII (Paraphrased by the Countess of Pembroke)
