Abstract: In the centrifugal barrel finishing machine of the type having X barrel assemblies, in which X is an integer, a method finishing workpieces whereby during a given total finishing time Y of the workpieces, each succeeding assembly containing finished workpieces is to be replaced with another assembly containing unfinished workpieces at the end of each time interval of Y/X. The workpieces in each succeeding assembly are finished X number of times each of which is for a duration of time equal to Y/X. In this way, the workpieces in each succeeding assembly can be replaced with workpieces to be finished as the finishing in the preceding unit has been completed, thereby permitting a continuous finishing process and barrel assembly replacement for each succeeding assembly without the need for exchanging the mass in all the barrel assemblies at the same time.

Abstract: For use with a container with a removable cover at the top opening, at least one pair of cover tightening members are pivotally linked with each other and are mounted to the cover so that they can be operated to tighten the cover to the container or release it from the container. Specifically, each of the tightening members has an internally threaded central bore through it for accommodating its operating member which is also threaded to engage the central bore. The tightening member further includes stationary or fixed pawls at both ends thereof that engage or disengage with the flanged lateral sides of the container. Thus, when the operating member advances through the central bore, the pawls are disengaged from the flanges to allow the cover to be removed from the container, and when operating members are retracted, the pawls are made to engage the flanges to tighten the cover to the container. In either case, one tightening member is operatively associated with the other by means of the pivotted links.
