a grinder attached to the drain of the kitchen sink to dispose of food waste (see Images 1 and 2).
Type: 5. Frequency — The term garburator is almost exclusively found in Canada (see Chart 1), though the US terms garbage disposal or garbage disposer are also in use (see Video).
The appliance was invented in 1927 by John W. Hammes in Racine, Wisconsin, and made available in 1938 as InSinkErator (R) (DiFulco 2007, see Image 1). Though an American invention, the dominant Canadian term is garburator, which is virtually unknown in the US.
See also COD-2, s.v. "garburator", which is marked "Cdn.", OED-3, which labels it "Chiefly Canad.".
