95 requiring but very little attention, and have punched 24-inch diameter holes in 4-inch plate. Several patterns of smaller punching and shearing machines always on hand. Davies’ Patent Self-acting STEAM STRIKERS, manufactured at the Viaduct Works, Crumlin. The silver medal was awarded to this invention, Paris Exhibition, 1867. A machine capable of taking the place of ordinary hand strikers at the smith’s anvil, and is specially constructed for striking blows at any angle inclined to the face of the anvil, from the vertical to the horizontal direction. Fig. 1 shows the striker in position for delivering vertical blows. It is adapted for all lunds of forgings required in engine, bridge, railway, anchor, ship, and general smiths work. Fig. 2 shows the striker in position for delivering blows at an angle of 45 degrees, for bending angle and T-iron, stiffeners, &c. It is so constructed as to turn on a vertical axis to work at any number of anvils or swage blocks placed within a circle of its radius; and the space occupied by it is not more than one-fourth of that required by hand strikers when working upon the same
