ANTIQUE BROWN & SHARPE BEAM TRAMMEL UNIVERSAL DIVIDERS This is an antique universal divider from Brown and Sharpe. I was, finally, able to identify it after finding it in their 1913 tool catalog. It's No, 843, but has the addition of the No. 845 steel beam trammels. It's a great old tool in fantastic condition and measures a bit over 5", end to end. I'll let the catalog describe it: This tool shows many points of excellence in design and construction. The scriber point holder has both fine and quick adjustment; the fine adjustment is obtained by a screw, enclosed in a beam, which engages the nut on the scriber point holder....... The scriber point is adjustable either side of the centre, and can be set for scribing small circles or for working close to a shoulder.....The posts are clamped by knurled nuts and held in place by spring friction when the nuts are unclamped for setting the points. The trams are clamped by knurled nuts to the beam, which is flattened on top, and the thrust taken by washers to prevent marring of the bearing surfaces.....One tram has an adjusting screw and slide, which is convenient for fine adjustment of the points. A swivel handle at the top of each tram is a noticable advantage, as it enables the trammels to be much more comveniently and accurately used than is possible with fixed handles. A pair of calipering points is furnished with these trammels.
