OR APPLICABLE TO PAPER MAKING MACHINERY."
"IMPROVEMENTS IN
This Invention relates to improvements applicable to paper making machinery,
pneumatic apparatus being arranged in combination therewith for the purpose of
taking off the sheet when cut from the cylinder of the machine, which apparatus
deposits the sheet on the ordinary receiving board, thus dispensing with hand
labour. For this purpose a combined hollow lever and horizontal arm is arranged to
move to and fro upon an axis at the side, or otherwise conveniently adjacent to the
paper making or cutting machine. The hollow horizontal arm carries a series of
perforated mouth pieces or projections which are caused to press upon the edge of
the sheet when it has to be removed from the cutter, and as the hollow arm set in
motion by the machine moves away from the cutter (the air being exhausted there-
from) the arm makes a partial revolution, which enables it to hold and carry and
deposit the sheet or sheets upon the receiving board, a tap worked by a lever
being opened and shut to admit and stop the air upon the sheet being taken up and
deposited.
The apparatus is so arranged as to be capable of adjustment for various sized
sheets of paper or cardboard.
The pneumatic mouth pieces and apparatus connected therewith may either be
worked from above or from below the cylinder of the cutting or paper making
machine.
I would remark that the arrangement, position, and construction of the parts may
be varied without departing from the nature of my Invention, which relates to
improvements in the arrangement and application of self-acting pneumatic
apparatus to the cutting apparatus of a paper making machine, or to the cutting
apparatus generally used by paper makers that cuts the sheets from the web, as
made into sheets of various lengths.

"IMPROVEMENTS IN
This Invention relates to improvements applicable to paper making and cutting
machinery, pneumatic apparatus being arranged in combination there with for the
purpose of removing the sheet when cut from such machines, which apparatus
deposits the sheet on a receiving table, thus dispensing with hand labor. For this
purpose a combined hollow lever is arranged to move to and fro upon an axis above
or below, or otherwise conveniently situated. The hollow arm carries one or more
perforated mouth pieces which are caused to press on the sheet of paper that
requires to be taken from the paper making or cutting machines, and as the
hollow arm (set in motion by suitable means) moves away from the place where
the sheet is to be taken from (the air having been previously exhausted therefrom)
the arm makes a partial revolution, which enables it to hold and carry and deposit
the sheet upon a receiving board, a valve or tap worked by suitable means being
opened and shut to admit and stop the air upon the sheet being taken hold of and
deposited.
The apparatus is so arranged as to be capable of adjustment for various sized
sheets of paper, or for taking several sheets side by side 'at one time, different
lengths of paper being taken off by adjusting the length of the swinging arm by
sliding the telescopic tube in or out.
The pneumatic mouthpieces and apparatus connected therewith may either be
worked from above or from below or at the side of the delivery or cutting end of
such paper making or paper cutting machinery.
And in order that my Invention may be clearly understood and readily carried
into practice I will proceed to describe the Drawings as annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side clevation, Figure 2 a back elevation, and Figure 3 a plan
of apparatus suitably arranged, in accordance with my Invention, for being applied
to paper making and cutting machines that deliver the successive sheets of paper
in a vertical direction.
Figure 4 shows a side elevation, Figure 5 a back elevation, and Figure 6 a plan
of similar apparatus suitably arranged, in accordance with my Invention, for being
applied to paper making and cutting machines that deliver the sheets of paper in a
horizontal direction.
In Figures 1, 2, and 3, A is a hollow lever attached to a rocking shaft B; C is a
lever having attached to it a connecting rod D, by means of which the machine is
driven; E is a tube sliding telescopically into the hollow lever A, and having at its
end a socket F in which the hollow arm G swivels or partially rotates. H is a
mouthpiece having through its face perforations to form suckers for holding the
sheet of paper; I, a screw rod that forms a connecting rod working from a pivot
to the arm G, and thereby causes the arm to rotate in the socket F. J is a valve
for shutting off and opening the communication between the mouthpiece and the
exhausting apparatus. K is a lever carrying another lever L, having at one end a
rod connecting it with the valve J. At the other end there is a roller 11 that
strikes against stops attached to a bracket M. These stops are adjustable to regulate
the admission and exhaustion of air through the valve J. N is a pipe con-
necting the valve J with the stuffing box O, to which the suction pipe from the
exhausting apparatus is attached. P, P¹ are standards forming the framing of the

page_text: apparatus; Q, the receiving tables on which the sheet of paper is deposited. The upper
portion or table proper is made to lower automatically, so that the sheets of paper
may be piled to a considerable height without interfering with the mouthpiece.
Means are provided for sliding a board or light table or tapes or strings to receive
the sheets while the pile of paper is being removed and the table raised to receive
a fresh pile. R are flyers or rods so arranged that they are caused to descend upon
the sheet of paper at about the instant of its being deposited on the receiving table
and so as to press and lay the sheets flat in succession on the table.
I will now proceed to describe the operation of the machine, as described in
reference to Figure 1.
By the use of an air pump or other suitable means a vacuum is produced and
maintained, and the vacuum being brought in connection with the machine, the air
is drawn in through the mouth pieces E, causing a strong suction, which will hold
firmly a sheet of paper or card against the mouth piece. Suction is caused through
the mouth piece H the air being drawn through the hollow swivelling arm F, the
sliding telescopic tube E, and hollow arm A, through the valve J, pipe N, and
stuffing box O, to the pipe leading to exhaust apparatus. The valve J controls the
communication of the exhaust pump with the mouthpiece, stopping or allowing
the exhaustion at the mouthpiece, or admitting the atmosphere to the inside
of the mouthpiece to cause the sheet to fall off. The mouthpiece H and arm A
being in a suitable position to take hold of the sheet, the mouthpiece being
pressed against or near to the sheet to be removed, the valve J being opened to
allow the suction at the mouthpiece, the sheet of paper is drawn against the mouth
piece. On the radial hollow arm A with the mouthpiece H being moved away
from the paper making or cutting machine, the mouthpiece H carries the sheet
back to such position as is desired (as shown by the firm lines), and on the suction
being cut off by the valve J and the atmosphere admitted the sheet falls on the
table Q as shown. The arm G partially rotates by means of the connecting rod I,
so that the mouthpiece is caused to assume a suitable position at all parts of its
motion. The arm then returns and the operation is repeated. The table Q on
which the sheets are received is caused to lower gradually by automatic means, so
that the top of the pile shall be always at a proper height from the mouthpiece;
the mouthpiece H can be adjusted to suit various lengths of sheets by the sliding
of tube E.
Figures 4, 5, and 6 illustrate an arrangement suitable for paper making and cutting
machines having an horizontal delivery.
A is the mouthpiece or suckers carried on the hollow bar B, which is carried by
slide block moving in the slido bar C and connected to levers D, D', by links E, E',
one link E' and lever D' being hollow to form means for exhausting air through
the mouthpiece. G is a shaft having fast on it levers D, D', working through
frainings F, F, and having one of its ends tubular, and fitted with a stuffing box H,
for the purpose of attaching the pipes from the exhausting pump. I is a lever
attached to shaft G and driven from suitable place on the paper making machine.
J is a table to receive the sheets. K is a valve by which the admission and
exhaustion of air to and from the mouthpiece is regulated.
The operation is as follows:-The mouthpiece being at the end of its motion and
over the sheet to be lifted at L, the communication with the air pump through its
valve K being then opened, the sheet of paper is sucked against the mouthpiece
and held there by the outside pressure of air; and on the mouthpiece being
moved backwards by the levers D, D¹, and shaft G (actuated by a connecting rod
driven from a suitable place on the machine from which the paper is to be taken
off), the mouthpiece carries the paper to the place where it is to be deposited, at
which point it is released by the closing of the communication of the mouthpiece
with the pump and the atmosphere admitted inside the mouthpiece, by which
means the sheets are dropped in a regular pile.
The receiving table is lowered automatically, so that the top of the pile is always
at a proper height from the mouthpiece. Means are provided of sliding a light

page_text: board or table or string to receive the sheets while the pile of paper is being
removed and the table is raised to begin a fresh pile.
Having thus described the nature of my Invention and the manner of performing
or carrying the same into practice, I would remark that I do not intend to confine
myself to the exact mechanical details herein before described, so long as the essential
character of my Invention is retained, neither do I claim any of the mechanical
parts taken separately, which are well known and in common use, but which in
their combination comprise the pneumatic and other automatic apparatus applicable
to paper making and cutting machinery in accordance with my improvements, but
what I claim is,-
The arrangement, construction, and combination of parts constituting the improved
pneumatic and other automatic apparatus, applicable to or combined with paper
making and cutting machines for taking off the sheet when cut and depositing it
automatically on the receiving board or surface, substantially in the manner and
for the purpose hereinbefore described and represented in the Drawings hereto
annexed.
In witness whereof, I, the said James Hird, have hereunto set my hand and
seal, this Third day of December, in the year of our Lord One thousand
eight hundred and eighty.
JAMES HIRD. (L.S.)
