ABSTRACT:
A tester of resistance of separate batches of tablets to breakage including a revolvable cylinder revolvable around a central height axis that extends axially of the cylinder, cylindrical space formed therein being divided into separate spaces by dividing walls extending radially across a diameter of the inner cylindrical space and the dividing walls for each space having a radially extending concave surface along one radius and a convex surface along another radius such that in each of the separate spaces there is formed a scoop facilitating collecting and tossing groups of tablets as the cylindrical cylinder revolves, and the revolvable cylinder including an access opening-structure for separate insertion and removal of tablets from the separate spaces before and after tumbling. The revolvable cylinder includes as a part of its combination, a motor mechanism for intermittently revolving the cylinder, and a male-female connection for mounting and dismounting in association with the motor mechanism. Also, the access opening-structure is preferably in the nature of a lid having central male or female structure that mates with an opposite female or male structure extending axially of the cylinder, facilitating the securing of the lid. Also, the edge of the lid is preferably stepped, to partially fit within space of the cylinder when mounted thereon, improving the securing of the lid onto the cylinder.
