This is apparently an article from Machinery magazine.
The first half is standard stuff about thread shapes. The second half describes making tools and gages, and might be interesting if a good copy could be found.
This is not a good copy. It is uncorrected OCR. The text itself is actually pretty good. However, it is largely useless because all of the diagrams that the text refers to are missing.
