Abstract:
1. In a chafing dish including a supporting frame and a cover element mounted for rotation about an axis passing through the body of said cover, improved means for progressively counter-balancing said cover comprising: a pair of pintles supporting said cover for movement about said axis, a lever extending laterally from at least one of said pintles, and fixed thereto at a first end thereof, a link having first and second ends, a first end being pivotally connected to said lever at a second end of said lever, a spring having first and second ends, said first end being connected to said second end of said link, said second end of said spring being connected to a peripheral location on said frame; whereby movement of said cover element from closed to open position results in progressive tensioning of said spring to provide a variable counter-balancing force to said lever as said link progressively approaches said pintle; said link surrounding said pintle after 180 degree rotation to cancel the counter balancing force of said spring.
