lessening the power. The pressure shoe is arranged to hold the "stuff"
at the very point of contact with the cutters, and, as we have shown, is
readily adjusted to a long or short cutter, so that a small molding can
be made as smooth as a large one, and so as not to require any finishing
with sandpaper or a hand tool.

The machine has also a bevel track very useful for picture frame
molding, and a patent cap of great value for the cutters, and readily
applied to any slotted head or common head. The wrenches that go with
the machine, and the common malleable iron caps for the top cylinder,
are shown in detail. These machines are now running in Worcester,
Boston, and Fitchburg, Mass.; Chicago, Ill.: Philadelphia, Pa.;
Brattleboro, Vt.; Whitesboro, N. Y.; Charleston, S. C., and other
places, and, it is claimed, are capable of doing better work and more of
it than any machine now in use.

This machine is covered by several patents taken through the Scientific
American Patent Agency. It is manufactured by R. Ball & Co., of
Worcester, Mass, to whom write for further information.
