ABSTRACT:
Vernier and/or dial caliper comparative reading point checking selective accessory attachments and their combinations, substantially add to the versatility of conventional vernier and dial calipers by their selective additions, which are all undertaken, quickly and conveniently, without altering the respective conventional calipers. Depending on the selection of such accessory attachments, otherwise hard or impossible dimension checking locations are quickly and conveniently reached, such as hard to reach slots, grooves, pockets, webs, etc. Each outside dimension locating leg, jaw, or blade of either a dial or vernier caliper receives a respective left or right positioning body of the accessory attachments, to interfit, via longitudinal slots of the body, a respective left or right leg, jaw, or blade, and to interfit, via transverse slots and transverse holes, respective contacting blades or respective contacting rods of the accessory attachments, used in reading respective inside and outside dimensions to thereby check dimensions at various selected points or locations throughout a machined part or product. Set screws are used to position and to hold the positioning slotted bodies in place on the caliper legs, and cap screws are used to position and to hold the respective contacting blades or respective contacting rods, on the positioning slotted bodies. Allen wrenches are used to tighten and to loosen the set screws and cap screws.
