THE BLAKE "LION AND EAGLE" CRUSHER,

A patented improvement of the former "New Pattern" Blake machine. Has

much greater efficiency than the old. It requires only about half the

power to drive, and is transported at much less expense (the size most

used weighing several thousand pounds less than the unimproved machine).

It requires less than half the time in oiling and other manipulation,

and less than half the expense for repairs. Address

E. S. BLAKE & CO., Pittsburgh, Pa., Sole Proprietors and Manufacturers.
