20,653. Oxley, T. Oct. 12. Yarn-testing machines; steelyard apparatus.- Relates to balances for ascertaining the loss or gain in weight by materials, e.g. cotton, after being dried or damped &c. and for other weighing-operations. The beam has lateral arms j, o for the bearings i, p, so that a rider n may be placed in the same vertical plane as these bearings, to be inoperative or to add its full weight to the weight in the scale-pan u. The bearings consist of cups and pointed screws, as shown. The material is suspended in a similar way by a hanger z from the arm l of the beam. By making the arm m twice the length of the arm l, and the weight at u four times the weight of the rider n, and, further, by dividing the arm m into twenty equal divisions, the number of divisions the rider is moved from the point o towards the point i represents the loss per cent sustained by the article. Other ways of graduating the beam may be employed.
