Mills on pillar-stand for grinding coffee and pepper, with two fly-wheels, friction boxes, and multiplying wheels.
[The ordinary mill in use for grinding coffee, pepper, etc., is extremely simple in its construction, and consists of a conical cylinder, which is cut into a series of ridges in its internal diameter: a taper piece of steel fits into this, and its outer diameter is cut with a corresponding series of ridges, but in the reverse direction; a temper pin regulates, by its projection, the fine or coarse quality of granulated particles, and the whole is set in motion by a winch handle. The addition of fly and multiplying wheels are not essentially parts of the mill, but they very materially facilitate the operation of grinding.— W. C. A.]
