Drop Press

Form of forging machine or hammer, in which a ram or monkey sliding uetween guides is raised to a height and is released to drop bpon the work on the anvil. The weight is lifted by two rollers at the top of the machine which seize on an oak plank secured to its top side. Provision is made to have the ram rise to the same height before being released, or else to deliver a succe ion of blows without readjustment. The control is by a foot-treadle, leaving the hands free for the work. This form of tool is specially adapted for forging in dies to produce complex shapes, as in gun and sewing-machine manufacture. One half the shape is on the anvil and the other half is on the bottom of the ram.
