Abstract
An apparatus for supplying polishing and/or cooling liquid, including a storage container preferably removably supported on a supporting frame, a downwardly facing dished cover for the container pivotally mounted on the frame by a hinge joint assembly and having a bent-over edge whose outer peripheral dimension is slightly smaller than the corresponding inside peripheral dimension of the upper edge of the container to provide a clearance gap therebetween, with the cover supporting thereon various elements such as a discharge pipe and a pump assembly for conveying liquid from the container as well as a mechanism for varying the temperature of the liquid, and stops on the cover and hinge joint assembly, respectively, for determining the range of movement of the cover between closed and open positions relative to the container.
