Abstract
The Invention is a three-wire apparatus for measuring an external thread. A single length of wire has a first bend and a second bend, which first and second bend divide the single length of wire into first, second and third wire portions. The first, second and third wire portions engage an external thread and are measured using a micrometer or other measuring device. Alternatively, the first, second and third wire portions are supported by a mounting block.
Claims13
A wire gauge apparatus for measuring an external thread, the apparatus comprising:
- a. a first wire portion;
- b. a second wire portion;
- c. a third wire portion, the external thread having a first flank and a second flank, said first and said second flanks being helical;
- d. means to selectably hold said first, second and third wire portions in engagement with said first and said second flanks of the external thread, said means adapting said first, second and third wire portions to be supported by the external thread against a pull of gravity when said first, second and third wire portions are in engagement with said first and said second flanks, said means further adapting said first, second and third wire portions so that said first, second and third wire portions support said means against said pull of gravity when said first, second and third wire portions are in engagement with said first and said second flanks;
- e. each of said first, second and third wire portions being substantially straight and substantially parallel to each other of said first, second and third wire portions when said first, second and third wire portions are in engagement with said first and said second flanks;
- f. said first wire portion being configured to engage said first flank of the external thread at a first location;
- g. said second wire portion being configured to engage said first flank of said external thread at a second location;
- h. said third wire portion being configured to engage said first flank of said external thread at a third location;
- i. the external thread defining a longitudinal external thread axis, said first, second and third locations defining a location plane when said first, second and third wire portions are in engagement with said first flank and said second flank, said external thread axis substantially falling on said location plane, said external thread axis separating a two of said first, second and third locations from the other of said first, second and third locations on said location plane when said first, second and third wire portions are in engagement with said first and said second flanks.
