hockey dasher (1926), dasher boards (1942)

[Mark A. Mandel]

Benjamin Zimmer <bgzimmer at RCI.RUTGERS.EDU> observes:
>>>
OED and MWCD11 don't have this sense of "dasher", but AHD4 does ('the
ledge along the top of the boards of an ice rink').  Dashboards for
vehicles were once called "dashers" too (back when a "dashboard" kept the
mud from dashing into your carriage).

And also way back whenyour shoes were protected from the same by
"spatterdashes", later (but still way before my time), abbreviated to
"spats".
