<p>INVENTOR LEO MATHIEU APPLICANT LEO MATHIEU A unitary device for relatively aligning two adjacent pipe flanges (end flanges of large pipes as are used in water, sewage and other installations) into registry so that the pipe flanges may be bolted into juxtaposition. The device includes an index finger which inserts into a bolt hole of one flange and an adjustable bolt adjustably positioned through an anvil member of the device and positioned over the adjacent flange. Turning down of the bolt on the one subjacent flange, urges that flange into registry with the other pipe flange for bolting together.</p> |
