Improvements in or relating to Paper Feeding or Delivering
Apparatus.
I, CZESLAW VICTOR RYMTOWTT-PRINCE, Gentleman, of 6, Boulevard de
Plainpalais, Geneva, Switzerland, do hereby declare the nature of this invention
to be as follows:-
The invention relates to a paper-feeding or delivering device, intended to be
combined with an automatical lifter or layer for printing machines and the
like, and especially intended to ensure the delivery one by one of the sheets
of a pile of paper to such automatical lifter or layer and to prevent a second
sheet from being accidentally withdrawn together with the first one by the said
automatical lifter or layer.
The said device is intended to be fixed to the back-edge of the table supporting
the paper to be fed or distributed.
To the said table there are provided two bearings for carrying transverse
shafts.
On the lower shaft there are fixed one or more arms by means of set screws each
arm carrying a tube forming a prolongation of the said arm and being fixed
in the desired position by means of a screw. The purpose of such prolongation
of the arm or arms is to render the apparatus described below adapted to work
upon any size whatever of paper.
To the inner end of the tube there is fixed a projecting arm bearing a roller
of gluish or slightly adhesive material a counter-weight fixed upon the transverse
shaft tending to press the roller or rollers upon the lower edge of the paper.
The device further consists of a rod or the like carried in the tube the direction
of which is substantially tangential to the roller so as to be able to move at
a small distance of the circumference of the latter when moved forward in the
tube as it will be hereinafter explained.
The one end of the transverse shafts is provided with the mechanism intended
to periodically cause the arms of the lower shaft to be lifted; the other end of
the said shaft is provided with the mechanism intended to periodically move the
rod in the tube forward or backward as will be explained.
carrying the tubes.
A crank lever acted upon by any suitable moving portion of the printing
machine, acts upon a rocking lever by means of suitable lever and rods. The
rocking lever is pivoted to one of the bearings on the frame and is formed as
a segment which is intended to engage the segment fixed to the lower shaft for
the purpose
of periodically rotating the same so as to raise or lower the arms
According to the actual length of the said arms that is to say, according as
the tube of the same is retracted or moved forward as a prolongation of same the
upper transverse shaft must be moved through a larger or smaller angle in order
to obtain the same elevation of the roller of adhesive material and therefore the
arm is provided with a set screw so as to allow the rocking movement of the

page_text: rocking lever to be exactly regulated according to the length of the said arms
so as to have the two segments engage more or less with each other
In order to allow this engagement to take place easily the segments are not
provided with teeth but formed the one with a V-shaped groove or recess and
the other with a V-shaped edge so that they engage frictionally with one another.
On the opposite end of the lower transverse shaft there is provided a segment
free from the said shaft and having its V-shaped groove engaging with the
V-shaped edge of a segment pivoted to the bearing attached to the frame and
connected by means of a rod to a slider moved to and fro by means of a rod
acted upon by any suitable portion of the printing machine or of the automatical
lifter or layer. The upper transverse shaft carries a pinion engaging with the
teeth of the segment on the lower shaft.
Each time this segment is oscillated in one or the other direction by the
segment engaging with it, it causes the upper transverse shaft to be rotated in
one or other direction.
To the upper shaft there are fixed in front of each arm of the lower shaft
arms the free end of each of which is forked and engages with
a lateral
projection of a red connected by means of a transverse bar to the rod in the
tube. The partial rotation of the upper transverse shaft in either direction causes
therefore alternately a forward or backward motion of the rod sliding in the
tube.
The rod and the devices acting upon the same might be replaced by other
suitable devices intended to press upon the back of the sheet of paper which is
to be prevented from being withdrawn by the one which is actually transported
by the apparatus described above.
The described device works as follows:-
The poise or counterweight presses the roller or rollers of adhesive material
upon the upper sheet of paper of the pile than owing to the to-and-fro motion
of the slider the arnis are raised and the rod in the tube is moved forward by
means of the described devices its edge bearing upon the back of the second
sheet. The parts of the device remain in this position whilst the transporting
or feeding device seizes the top sheet and delivers it to the printing cylinder.
Precisely at that moment the arm or arms are falling down and lifted again,
the roller or rollers of adhesive material carried thereon raising thereby the
edge of the second sheet and the rod pressing upon the edge of the next sheet
to prevent its being raised with the preceding sheet.

Improvements in or relating to Paper Feeding or Delivering
Apparatus.
I, CZESLAW VICTOR RYMTOWTT-PRINCE, Gentleman, of 6, Boulevard de
Plainpalais, Geneva, in Switzerland, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
The invention relates to a paper-feeding or delivering device, intended to be
combined with an automatical lifter or layer for printing machines and the
like, and especially intended to ensure the delivery, one by one, of the sheets
of a pile of paper to such automatical lifter or layer and to prevent a second

page_text: sheet from being accidentally withdrawn together with the first one by the said
automatical lifter or layer.
In the accompanying drawings,
Fig. 1 is a side-elevation of the paper-feeding device.
Fig. 2 is a section of the same; the arms 4 being depressed.
Fig. 3 is a side-elevation of the same device seen from the opposite side of the
machine; the arms 4 being depressed.
Fig. 4 is a section of the arms 4 when lifted.
The said device is intended to be fixed to the back-edge of the table supporting
the paper to be fed or distributed.
To the said table there are provided two bearings 1 and 1* for carrying the
transverse shafts 2 and 3.
On the shaft 2 there are fixed one or more arms 4 by means of set-screws 5,
each arm 4 carrying a tube 6 forming a prolongation of the said arm, and being
fixed in the desired position by means of a set-screw 7. The purpose of such
prolongation of the arm or arms 4 is to render the apparatus described below
adapted to work upon any size whatever of paper the figures of the drawing
showing the same applied to the largest size for which the table has been
constructed.
To the inner end of the tube 6 there is fixed a projecting arm 8 bearing a
roller 9 of gluish or slightly adhesive material, a counter-weight 10, acting upon
the shaft 2, tending to press the roller or rollers 9 upon the lower edge of the
paper.
The device further consists of a rod 11 or the like carried in the tube 6 the
direction of which is substantially tangential to the roller 9 so as to be able
to move at a small distance of the circumference of the latter when moved
forward in the tube as it will be hereinafter explained.
One end of the shaft 2 is provided with mechanism (Fig. 3) intended to
periodically cause the arms 4 of the shaft 2 to be lifted the other end of the
said shaft is provided with the mechanism (Fig. 1) intended to periodically move
the rod 11 forward or backward as will be explained.
A crank lever 12 (Fig. 3) acted upon by any suitable moving portion of the
printing machine, acts upon a rocking-lever 16 by means of suitable levers and
rods 13, 15 and 14. The rocking-lever 16 is pivoted at 17 to the bearing 1 and is
formed as a segment which is intended to engage the segment 18 fixed to the
shaft 2 for the purpose of periodically partly rotating the same, so as to raise
the arms 4 into the position shown in Fig. 4, or to lower the same into the
position shown in Fig. 3.
According to the actual length of the said arms 4, that is to say, according as
the tube 6 of the same is retracted as shown in the drawings or moved forward as
a prolongation of same, the shaft 2 must be moved through a larger or smaller
angle in order to obtain the same elevation of the roller 9 of adhesive material,
and therefore the arm 4 is provided with a set-screw so as to allow the rocking-
movement of the rocking-lever 16 to be exactly regulated according to the
length of the said arms 4 so as to have the segment 16 engage more or less with
the segment 18.
In order to allow this engagement to take place easily the segments 16 and 18
are not provided with teeth but formed the one with a V-shaped groove or
recess and the other with a V-shaped edge, so that they engage frictionally with
one another.
On the opposite end of the shaft 2 there is provided a segment 19, free on
the said shaft, and having its V-shaped groove engaging with the V-shaped
edge of a segment 21 pivotted to the bearing 1 and connected by means of a rod 23
to a slider G, moved to and fro by means of a rod g acted upon by any suitable
portion of the printing-machine or of the automatical lifter or layer. The shaft 3
carries a pinion 3* engaging with the teeth 20 of the segment 19.

page_text: Each time this segment 19 is oscillated in one or the other direction, by the
segment 21, it causes the shaft 3 to be rotated in one or other direction.
To the shaft 3 there are fixed in front of each arm 4 of the shaft 2, .arms 24
the free end of each of which is forked and engages with a lateral projection 25
of a rod 26 connected by means of a connecting bar 27 to the rod 11. The
partial rotation of the shaft 3 in either direction causes therefore alternately
a forward or backward motion of the rod 11 sliding in the tube 6.
The rod 11, and the devices acting upon the same, might be replaced by other
suitable devices intended to press upon the back of the sheet of paper which is
to be prevented from being withdrawn by the one which is actually transported
by the apparatus described above.
The described device works as follows:-
the
The poise 10 presses the roller, or rollers, 9 of adhesive material upon
upper sheet of paper x of the pile X; then owing to the movement of the
segments 16 and 18, and that of the segments 19 and 21 produced by the move-
ment of the slider G, the arms 4 are raised, thus lifting the top sheet of paper,
and the rod 11 is moved forward by means of the described devices, its edge
bearing upon the back of the second sheet 2. The parts of the device remain. :n
this position whilst the transporting or feeding device (not shown) seizes the
top sheet and delivers it to the printing cylinder. Then the arm or arms 4
are moved down and lifted again, the roller or rollers 9 of adhesive material
carried thereon raising thereby the edge of the second sheet 3; and the rod 11
pressing upon the edge of the succeeding sheet; to prevent its being raised
with the sheet, which is then removed, & so on.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. A device intended to prevent the accidental withdrawal of more than one
sheet of paper at a time by an automatical lifter or layer for printing-machines
and the like, comprising a shaft provided with an adjustable arm or arms bearing
suitable means for engaging and periodically raising the upper sheet of paper,
rod or rods or their equivalent intended to periodically press upon the sheet
of paper directly below the one raised by the arm or arms and combined with
suitable means for periodically raising or lowering the arms and means for
periodically moving the rod or rods or their equivalent for the purpose specified.
the complete
2. The combination and arrangement of parts constituting
apparatus for raising the top sheet of paper and holding down the succeeding
sheets substantially as described or illustrated in the accompanying drawings.
