Description:
Abstract:

The present invention relates to the mechanism for effecting the rotation of the scraper ring or plate F or its adjustment around its vertical axis. To accomplish this, a series of gear-teeth are formed along the inner edge of the ring, they being concentric with its axis and of a number sufficient to permit as wide a range of adjustment as is desired.

Claim:

In a machine of the class described the combination with the adjustable scraper, the means for adjusting it, and the lock, entirely independent of the said adjusting means, for holding the scraper after adjustment, of a power-transmitting device adapted to actuate both the lock and the adjusting means.
