Patent 7584915 was granted and assigned to Emerson Electric on September, 2009 by the United States Patent and Trademark Office.
A food waste disposer includes a housing defining an inlet opening and a grinding mechanism driven by a motor for grinding food waste received into the housing through the inlet opening. An annular retaining collar has one end for connecting to a sink opening, via a standard sink mount, for example. An annular elastomeric coupler is situated about the opposite end of the annular retaining collar and connected to the housing for vibrationally isolating the annular retaining collar from the housing. The primary loading on the elastomeric material is in shear. Elastomeric materials in shear are particularly effective in absorbing both vibration and shock loads.
