One of the shafta
cheeks of a frame which can be clamped to a table or bench
18 extended outside the frame and is similarly provided with leather washer clamped
on but of smaller size. The large rollers which as before mentioned revolve in
the same dnection through an intermediate gear have no tendency to draw a knife

A, A, ale two rollers preferably of the same diameter and composed of buff' or
like leather washers cramped upon a square shaft by end collars B, B, screwed on
to put the washers into close solid contact and there held The upper shalt is
shown longer than the lower one and the extension C is similarly covered with leather
washers cramped ou. The two rollers are mounted between side cheeks D, D', of
a frame provided with a clamping leg E and screw Flor securing the article to a
table, a bench, or the like.
Each shaft carries a toothed wheel G, G, and these are geared into by an ille
or intermediate gear wheel H in order that the two rollers A, A, shall move or
rotate in the same dnection when the winch handle I is tuined.
The rollers A, A, are capable of adjustment by thumb screws J. J. the stems of
which press on the upper bearings K, K, having the shafts passed through them,
and in the bottom hollow of the frame are springs K' for the lower bearings to
rest on
Between the eud cheeks D, D', of each side frame shaped blocks of hard wood
can be jammed as a protection to the cutting edges of knives cleaned by the rollers
whilst being inserted or withdrawn.
The rollers A, A, can readily get their supply of cleaning or polishing powder
from the trough M by the lower of the rollers iotating therein.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same is to be performed I declare that what I
claim 18:-
