of same place.--In this machine there is a new construction of the
brush drum for simplifying the same, and facilitating the application
of the brush wings, so that they can be readily taken off and put on;
also, an arrangement of the ribs between the saws for facilitating the
separating of the seed from the cotton without breaking and injuring
the fiber. There are also ingenious devices for preventing the seed
from gathering and clogging at the ends of the saw drum.
