Description: |
| William C. Wood - patent attorney
The main object of my invention is an absolutely accurate gage, susceptible of varied uses, capable of adjustment at each and every point wherein a wear of contacts would derange accuracy, and which can be produced at reasonable cost. Certain portions of my invention can be employed in caliper-gages otherwise varied in construction, but when all of said improvements are embodied in what I deem their best form my gage has a shank or beans having a rigid rectangular head or jaw at one end thereof, a sliding serrated bar on said shank controlled longitudinally by a gage-screw, and a movable rectangular head or jaw which slides on said shank, and has a locking-plate by which it may be secured to said bar or detached therefrom and moved independently thereof. A caliper-gage as thus briefly described is believed to be broadly new, with or without certain novel features which I have devised and embodied therein, and which can also be employed with equally desirable results in caliper-gages having no sliding serrated bar, but in lieu thereof a gage-screw which extends throughout the length of the shank, and are equally applicable to caliper gages having a head or jaw which is moved by a gage-screw, and a second head or jaw which is movable but wholly independent of said screw. |
