The bar is swung on the pivot by means of the strain through the wire on the spur (lug perhaps is the better term), and so forces the free end to assume a movement through a quarter circle towards the platen. It will also be noticed that there is a spiral spring, one end of which is attached to the framework of the machine, the other to the type-bar, so that, directly the type lias struck the paper the spring takes up the natural tendency to rebound, and brings the bar down rapidly, but without force or shock, to its bed. The whole movement may be clearly gathered from the diagram. The inking arrangements of the Sun are as novel as its type-bar. The illustration shows how it is effected. To the right is a circular pad, freely revolving on a pivot. This pad, which may be readily changed for another of different colour, is of felt, and supplies the smaller roller (shown in black) towards the left of the illustration. This
