Abstract
This invention relates to a gauge device which may be used by a toolmaker or machinist to determine the squareness of surfaces on a workpiece. The device has a handle having a gauge mounted adjacent an end of the arm opposite the handle and an intermediate contact point such that the inner surface of the handle and the intermediate contact point define the planes of the surfaces of the workpiece to be measured. The device is easily used, easily transported, and capable of use with work-pieces having chamfered or otherwise altered corners, holes, slots or other imperfections that make determination of squareness difficult.
Claims13
An angle measuring apparatus adapted to measure an angular deviation from a specified angle between first and second surfaces of a workpiece, comprising:
- a handle having a face on one surface for contacting the first surface of the workpiece and an opening passing through said handle;
- an arm slidably received in said opening;
- means for locking said arm in a fixed position relative to said handle;
- an angle deviation means for determining, in conjunction with said handle, the angular deviation of the second surface from the specified angle between said first and second surfaces of the workpiece, said angle deviation means comprising a guage fixedly mounted to said arm adjacent to an end of said arm opposite the face of said handle and having a feeler point for contacting the second surface of the workpiece, and a contact member slidably mounted on said arm between said gauge and said handle, said contact member contacting the second surface of the workpiece.
