MAINWARING, Mechanic, Ystalyfera, South Wales, do hereby declare the nature
of this invention to be as follows:-
This is an invention for cleaning and polishing metal plates and sheets, and
consists of an arrangement of rollers in pairs, having surfaces of suitable material;
the two rollers of each pair revolving at different speeds, and they are kept apart
at the proper distance by springs inserted between the bearings; as the. surfaces
wear the slack taken up by screwing them together. The plate is delivered to
the first pair and by them passed on to the next without the intervention of any
carrying rollers. In consequence of the rollers turning at different speeds both
surfaces of the sheet is rubbed alternately by the top or bottom rollers of the
successive pairs; or the rollers may be joined by belts which would be running at
different speeds, and the plate would be simultaneously carried forward, and rubbed
between the surfaces of the upper and lower belts.
For polishing tinplates it is only necessary to pass them through the machine,
but for removing the grease, the rollers or belts must be fed with bran or some
other cleaning material.

MAINWARING Mechanic Ystalyfera, South Wales, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention consists of four or more rollers of the same diameter arranged in
pairs having surfaces of suitable material preferably sheepskin. Each pair is in
the same plane as the one following, so that the "nip" is opposite. The two
members of each pair run at different speeds, in the following manner, that is to
say, the lower roller of the first pair A and the upper one of the second, A revolve
at the same rate, but the others at a considerably faster speed, and so on alternately
throughout the series.
The effect of this is that the plate or sheet entering between the first pair, travels
at the rate of the slow rollers, and is rubbed alternately on both surfaces by the
quick rollers. The rubbing surfaces may be extended by coupling two slow and
two quick rollers together by means of a belt whose width is equal to their length;
the surfaces of these belts will form the rubbers.
Each pair of rolls is in contact, but kept from undue friction by means of
springs B inserted between the bearings; as the surfaces wear they are brought
closer together by means of screws C.

page_text: The pinion F on the axle of the driving pulley E is geared into the cog
wheels G G G G which turn the rollers at the other end of which are the
wheels D, these gear into the pinions A on the spindles of the rollers A' by which
means the two rollers of each pair are made to revolve at different speeds. The
plates are put in at H and are delivered cleaned and polished at K.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is,
1. The differential speed of the rollers for the purpose of simultaneously carrying
forward and rubbing the plates or sheets.
2. The contrivance for keeping the roilers in contact without undue friction.
