Moxis Posted April 15, 2016 #1 Posted April 15, 2016 I wonder for which use is this nice brass "glasses"? Some kind of gauge also? WackoWolf, Canute, thibaultron and 1 other 4
HSM Posted April 15, 2016 #2 Posted April 15, 2016 My guess is that is a measuring tool. If you open it up and then touch one of the the openings to both sides of a material you can measure the thickness of that material by measuring the opening at the opposite end. Measuring the thickness of a ship's boat would be a good application for that tool. mtaylor, justsayrow, WackoWolf and 2 others 5 From about as far from the ocean as you can get in North America!
miloman Posted April 15, 2016 #3 Posted April 15, 2016 I've seen this used by jewelers to measure thickness of metal. Not sure if that's the primary use or what the other part is. Milo Canute and mtaylor 2
Bob Blarney Posted April 17, 2016 #4 Posted April 17, 2016 (edited) Calipers. I believe that the crossbar was used to fix the jaws after application to the unknown material, and then the opening was fitted to a set of feeler gauges, such as for automotive work (ignition contact points). A much larger instrument of this sort is still used by woodturners, and for use with a planer. Edited April 17, 2016 by Bob Blarney
