  • Patent number: 4377089
    Abstract: Apparatus for compressive testing of a test specimen may comprise vertically spaced upper and lower platen members (1 and 2) between which a test specimen (T) may be placed. The platen members are supported by a fixed support assembly (3, 5, and 6). A load indicator (14) is interposed between the upper platen member (1) and the support assembly (6) for supporting the total weight of the upper platen member (1) and any additional weight which may be placed thereon. Operating elements (8 and 17) are provided for moving the lower platen member (2) upwardly toward the upper platen member (1) whereby an increasing portion of the total weight is transferred from the load indicator (14) to the test specimen (T).The testing apparatus may include limit devices (20 and 22) for limiting the movement of the lower platen member (2) toward the upper platen member (1) to prevent permanent deformation in the test specimen (T).
