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:
“Any balance we achieve between adult and parental identities, between children’s and our own needs, works only for a time—because, as one father says, “It’s a new ball game just about every week.” So we are always in the process of learning to be parents.”
—Joan Sheingold Ditzion, Dennie, and Palmer Wolf. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 2 (1978)
““It’s hard to tell you how I managed it.
When I saw the shaft had me by the coat,
I didn’t try too long to pull away,
Or fumble for my knife to cut away,
I just embraced the shaft and rode it out....””
—Robert Frost (1874–1963)
