Abstract
Mounting apparatus for attaching a dial gauge to the housing of a hardness tester in which is carried a load cell. The dial gauge may have a housing in which is carried an operating mechanism and a dial indicator and from the base of which extends a plunger for engagement with the plunger rod of the load cell and responsive to movement thereof for actuating the operating mechanism and the dial indicator. The mounting may comprise: a cap member attachable to one end of the tester housing having a central aperture therethrough and a support member attached to the cap member to which is attached the dial gauge so that the dial gauge plunger is centrally and freely disposed in the cap member aperture. The cap member is attachable to the tester housing so that the dial gauge plunger engages the plunger rod centered in the load cell in a predetermined relationship but is removable so that the cap member, support member and dial gauge may be removed from the tester housing without relative movement therebetween.
