A supplement to Ures Dictionary of Arts, Manufactures, and Mines, : containing a clear exposition of their principles and practice. . which the cylinder is made to travel bythis most beautiful micrometric arrangement is very small. The drag bench was inventedby the late Mr. Barton, and may be viewed as the greatest addition to the machinery of theMint ever yet or ever likely to be introduced ; for by its agency, when intelligently man-aged, the fillets of silver coming from it are so perfect that for days together the blanks cutfrom them are found to contain only 1 in 400 out of remedy, and it is quite a common oc-currence to find only 1 in 800, and from gold fillets blanks are cut in which only 1 in 100,and even 1 in 200 are rejected as being out of remedy. To the drag bench are fixed two pairs of hand shears, by which the fillets are cut intofour lengths. They are then passed on to the trier, who, by the hand-cutter shown at , punches out one or more blanks from each piece of fillet, and weighs it in a delicatebalance placed close beside him. The fillet is placed on the bolster a, and the trier, holding 454.
