J. B. Creighton, of Tiffin, Ohio, has made an improvement in the mode of constructing stump machines. The plan adopted by the inventor, Mr. C, is to place a large screw vertically in the frame, and so constructing a nut to work upon this screw, above the frame, that a sweep may be attached to it permanently and with convenience. The power being applied to this sweep, raises the stump perpendicularly from its firm bed. The nut turns with the sweep, but the screw is prevented from turning by its attachment to the stump Another teature of the invention consists in constructing adjustable rollers, by which the machine may be transported from one place to another with great ease. Measures have been taken to secure a patent.
