Abstract

927,141. Testing hardness. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 3, 1960 [Oct. 2, 1959], No. 33930/60. Class 106 (2). In a hardness testing instrument a penetration member 2 is loaded via a lever 19 by weights 33 slidable on a tube 22. Each weight 33 has a pair of lugs 37, staggered from the lugs 37 on other weights. When tube 22 is lowered to load the lever 19 the hugs on one of the weights 33 engage shoulders 60 on the casing thus prevent ing the weight in question and all overlying weights from loading the system. The weight whose lugs 37 are aligned to engage shoulders 60 can be selected by rotating a member 30 having teeth 60 which rotate the weights 33. The penetration member 2 may be mounted on a head 9 which is revolvable to allow a different penetration member such as 8 to be used.
