"IMPROVE-
MENTS IN AND CONNECTED WITH MACHINES FOR FINISHING PRINTED SHEETS OF
PAPER."
My Invention relates to improvements in and connected with the machines or
apparatus for which Her Majesty's Letters Patent, No. 1746, of the year 1808, and
No. 1728, of the year 1872, were granted to me, that is to say, machines in which
the printed sheets of paper are finished by being passed through between and
in direct contact with rotating smooth rolls called "set-off rolls," and consists,-
First. As means for ensuring that the whiting or other powdery matter shall be
equally and evenly distributed on the surface of the rolls, in causing such whiting
or other powdery matter to fall directly on to the surface of the said rolls in a
shower instead of falling first on to a buffing or like roll.
Second. As means for effectually removing the ink, set-off, and powdery matter
from the surface of the rolls in employing two or more cylindrical brushes revolving
in contact with the said set-off rolls. The brushes are formed of bristles, wires,
or their equivalents, placed continuously, spirally, or in any other desired manner
on shafts or rollers, and the said brushes are caused to revolve rapidly in the same
or in opposite directions to the set-off rolls; and they may, if desired, have a
longitudinal reciprocating motion given to them.
Third. As means for cleaning or removing the ink, set-off, and powdery matter
from the brushes, in so placing an adjustable straight edge or thin strip of metal or
stiff material that the bristles, wires, or their equivalents on the brushes strike
against the edge of the said straight edge.
Fourth. As means for preventing the ink, set-off, and powdery matter removed
from the set-off rolls by the brushes from again coming in contact with the said
set-off rolls, in employing troughs, receptacles, or collectors to receive the said ink,
set-off, and powdery matter as it leaves, or is delivered from the brushes.
Fifth. As means for ensuring that the printed sheets of paper shall be delivered
from the set-off' rolls in the desired direction, in attaching a series of needles or
pointed strips of metal or stiff material to a bar in such manner that they shall be

page_text: adjustable longitudinally. The points of the said needles or their equivalents rest
against the rolls; springs or like means may be used to keep the needles in
position.
The whole machine is enclosed in a casing provided with an exhaust pipe or pipes
through which any floating dust may be drawn off.
DESCRIPTION OF THE DRAWINGS.
First. 1 are the vibrating whiting containers, delivering whiting direct to
the rolls 2.
Second. 3 are the revolving brushes for removing the ink, set-off, and powdery
matter from 2.
Third. 4 are straight edges or pieces for. removing the set-off and powdery
matter from the brushes 3.
Fourth. 5 are troughs for catching the set-off and powdery matter removed from
the brushes 3.
Fifth. Gare needles or pointed strips of metal adjustable along the rods 7 by the
set screws 8 for ensuring that the finished sheets of paper shall be delivered on
the board 9; the paper to be finished enters at 10. The arrows show the direction
of motion.
