PHILIP MIDDLETON JUSTICE, of 14, Southampton Buildings, in the County of
Middlesex, Patent Agent. IMPROVEMENTS IN AND CONNECTED WITH APPARATUS
FOR FEEDING SHEET PAPER TO PRINTING, RULING, FOLDING, CALENDERING, AND
LIKE MACHINES." A communication from abroad by the Sedgwick and Stuart
Manufacturing Company (Incorporated), of Poughkeepsie, in tlie State of New
York, United States of America.
This Invention relates to a class of mechanism devised for the purpose of feeding
sheet paper automatically to any and all kinds of machinery where it may be
necessary to feed such paper as in ruling and calendering machines, printing
presses, and machines of a like nature, in fact it is applicable in most every case
where sheet paper is fed by hand. Hitherto various devices have been used for
the purpose, but with results that have not proved satisfactory. The air or suction
machines have proved too complicated and uncertain in consequence of the cracking
of the flexible air tubes, the leakage of air in other ways destroying suction, their
failure to handle torn sheets, or to separate perforated sheets. Others applied to
ruling machines that have separated the sheet by frictional or by mechanical means,
wherein the sheet is removed from the pile by nippers moving upon long swaying
arms, have produced so much vibration while being rapidly operated that it has
proved almost impossible to effect a perfect ruling of the sheet owing to the jarring of
LD071

page_text: the pens. Again, in the endeavour to make the machine automatic it is important
that the feed table holding the paper should adjust itself to the buckling and
separating mechanism. In some cases this has been partially but not completely
done, or, in other words, by the use of the screw, ratchet, and pawl, as ordinarily used
in paper-making machines for lowering the table receiving the paper, the movement
being reversed. The paper has been fed upwards at regular intervals and at regular
distances without being governed at all by the thickness or thinness of the paper
or the amount displaced, and in case the uppermost sheet was not raised to a
sufficient height to admit of obtaining the required pressure or friction upon its
surface it became necessary to regulate it by hand; sometimes, again, it would be
raised too high and require similar attention. The object of this Invention is to
overcome these defects and make a practical working machine well adapted to the
wants of the trade, and one that in case it fails to feed a sheet of paper will stop
of itself, and not damage the blanket or waste material, and to this end the
Invention consists,
1stly. Of a machine for feeding sheet paper having a movable table secured to
nuts working upon vertical screws by which the said table is raised or depressed,
the said nuts being provided with extensions or guide plates, to each end of which
are attached friction rollers which move in grooves or passage ways formed upon
the side of the main frames by raised beads, ribs, or the equivalent thereof, thereby
relieving the vertical screws which operate the table or support for the paper from
any undue lateral strain in case a heavy body of wide paper should be piled upon
the feed table and the weight be greater upon one side of the centre of said table
than the other, and
2ndly. The Invention also consists of a machine for feeding sheet paper having
an adjustable foot or clamp which serves to hold the paper during the operation of
buckling, or the rubbing back and forth of an edge or part of a sheet of paper
preparatory to its separation from a pile of paper, or its removal from the feed
table, the said plate being pivotted and slotted in a manner to admit of its
conforming to any unevenness of the surface of the paper and which is capable of
being removed therefrom at the proper time to permit the sheet to be withdrawn
free from its pressure, and which is also applicable with other mechanism with
which it is used for controlling the movement of the feed table; and
3rdly. The Invention also consists of an improved device for buckling paper
having an adjustable arm pivoted in such a manner as to admit of pressure being
applied to or removed from one of its ends capable of being used at a greater or
less distance from the edge of the paper, and attached thereto a piece of rubber or
other material having a good frictional surface for rubbing the paper, used in
combination with a roll, finger, or rest, also connected to a pivoted reciprocating
arm which may rest upon the surface of the paper and which is adjustable to
admit of the separation or drawing together of the said roll, finger, or rest, and the
rubber pad, as the paper may differ in thickness or weight, the two arms being
capable of being raised to remove the rubber and rest from the surface of the
paper to permit the removal of the sheet, and
4thly. The Invention further consists in a pivoted separating plate having a
horizontally reciprocating and vertical motion to aid in a more effectual separation
of the sheet, and to permit the operation of buckling to begin before the said plate
has been entirely withdrawn from its advanced position, and
5thly. The Invention also consists in a separating mechanism having a separating
plate or bar and a movable frictional surface which may be introduced beneath a
sheet of paper, and co-operating with a frictional and movable surface upon the
upper side thereof, by which the said sheet is separated and removed, and
6thly. The Invention also consists of a retarding device for checking the rapid
forward motion of the paper when discharged from the separating rolls, that the
sheets may not be allowed to move with greater speed than the carrying tapes.
thereby ensuring a proper register of the paper, which consists of a frictional

page_text: surface pressing upon the underside of said paper co-operating with a frictional
surface bearing upon its upper surface, and operating upon the paper before its
passage over the tapes, and
7thly. The Invention further consists in a device for the automatic regulation of
the ascent of the feed table, whereby the surface of the paper or uppermost sheet is
presented at the required height for the operation of the separating mechanism, and
8thly. The Invention further consists of a stop motion whereby the operation
of a paper feeding device for feeding sheet paper may be discontinued by the
omission to interpose a sheet of paper between a pivotted or slotted toe or armi
connected with the belt or clutch shifter and a part of the operating mechanism of
the machine, the motion and action of all said parts being regulated and governed
by means of the known graving, operating, and driving mechanism now in general
use.

PHILIP MIDDLETON JUSTICE, of 14, Southampton Buildings, in the County of
Middlesex, Patent Agent. IMPROVEMENTS IN AND CONNECTED WITH APPARATUS
FOR FEEDING SHEET PAPER TO PRINTING, RULING, FOLDING, CALENDERING, AND

it would be raised too high and require similar attention. The object of this
Invention is to overcome these defects and make a practical working machine well
adapted to the wants of the trade, and one that in case it fails to feed a sheet of
paper will stop of itself and not damage the blanket or waste material, and to this
end the Invention consists,-
1stly. Of a machine for feeding sheet paper having a movable table secured to
nuts working upon vertical screws by which the said table is raised or depressed,
the said nuts being provided with extensions or guide plates, to each end of which
are attached friction rollers which move in grooves or passage ways formed upon
the side of the main frames by raised beads, ribs, or the equivalent thereof, thereby
relieving the vertical screws which operate the table or support for the paper from
any undue lateral strain in case a heavy body of wide paper should be piled upon
the feed table and the weight be greater upon one side of the centre of said table
than the other, and
2ndly. The Invention also consists of a machine for feeding sheet paper having
an adjustable foot or clamp which serves to hold the paper during the operation of
buckling, or the rubbing back and forth of an edge or part of a sheet of paper
preparatory to its separation from a pile of paper or its removal from the feed

having an adjustable arm pivoted in such a manner as to admit of pressure being
applied to or removed from one of its ends capable of being used at a greater or

rubber pad, as the paper may differ in thickness or weight, the two arms being
capable of being raised to remove the rubber and rest from the surface of the paper
to permit the removal of the sheet, and
4thly. The Invention further consists in a pivoted separating plate having a
horizontally reciprocating and vertical motion to aid in a more effectual separation
of the sheet, and to permit the operation of buckling to begin before the said plate
has been entirely withdrawn from its advanced position, and
5thly. The Invention also consists in a separating mechanism having a separating
plate, or bar and a movable frictional surface which may be introduced beneath a
sheet of paper, and co-operating with a frictional and movable surface upon the
upper side thereof by which the said sheet is separated and removed, and
6thly. The Invention also consists of a retarding device for checking the rapid
forward motion of the paper when discharged from the separating rolls, that the
sheets may not be allowed to move with greater speed than the carrying tapes,
thereby ensuring a proper register of the paper, which consists of a frictional
surface pressing upon the under side of said paper co-operating with a frictional
surface, bearing upon its upper surface and operating upon the paper before its
passage over the tapes, and
7thly. The Invention further consists in a device for the automatic regulation of
the ascent of the feed table, whereby the surface of the paper or uppermost sheet
is presented at the required height for the 'operation of the separating mechanism,
and
:
8thly. The Invention further consists of a stop motion, whereby the operation of
a paper feeding device for feeding sheet paper may be discontinud by the omission
to interpose a sheet of paper between a pivoted or slotted toe or arm connected
with the belt or clutch shifter and a part of the operating mechanism of the
machine.
The motion and action of all said parts being regulated and governed by means
of the known gearing, operating, and driving mechanism now in general use.
To clearly show how this Invention may be practically employed, reference is
made to the annexed Drawings, in which similar letters represent similar parts in
all the views.
Fig. 1 is a view in elevation of the rear part of the machine.
Fig. 2 is a view in elevation of the left hand side of the machine, showing the
cam which operates the vertical screws used in moving the feed table.
Fig. is a view in section as seen from the left hand side of the machine, with
the left-hand frame removed to show more plainly the cams that actuate the
various levers and other operating mechanism.
. Fig. 4 is another view in section with left-hand frame removed, showing the
vertical screws which move the feed-table, the guide plates and friction rolls, the
feed table witli paper and paper guards, the buckling device, and the cams which
actuate the buckling device and separating plate.
Fig. 5 is a plan or top view of the mahine showing both sides of the frame, the
feed table with guards to hold the paper in place, the screws by which the table is
moved, the ratchet wheel and pawl for turning said screws and the buckling

page_text: devices, the tape rolls with tapes, the regulating roll upon movable arms, which
admit of its being raised from the paper or pressed thereupon when required, the
registering plate or guide, and the driving and main shafts.
Fig. 6 represents a view of the rubbing and buckling device, detached and
enlarged to show more plainly the combination of the rubber and the roll, each
upon separate arms, which in turn are pivoted to another pivoted arm, having slots
to admit of their adjustment, by which means the buckling device is made to press
upon the paper with an unvarying pressure; the means for increasing or decreasing
the pressure upon the rubbing pad is also shown, also the rod or slide by which
the buckling device is raised to permit a sheet to be withdrawn and the relative
positions of the different parts, while the buckling device is buckling or arching a
sheet of paper before the separating plate is entirely withdrawn from its advanced
position.
Fig. 7 represents the arrangement of levers in combination with a link,. ratchet,
screw, weighted pawl, the regulating pressure arm which bears upon the surface of
the paper and determines the distance which it shall be moved, the cams which
actuate said levers and the pin or stop having an inclined or angular surface
which determines the length of stroke or movement of pawl.
Fig. 8 represents the side of the frame with clutch attachment and movable arm
which is connected to the end of the stop-motion lever, shown upon the side of
the frame in Fig. 2, and by which the shifter is moved and the machine stopped
whenever it fails to feed.
C
Fig. 9 shows the buckling device in the act of buckling or arching a sheet of
paper preparatory to its removal, while the separating plate is receding from its
advanced position, having just discharged a sheet of paper, the bent arm by which
the said blade or plate is held in a raised position, and the lever which actuated by.
à cam applies the pressure thereto, as will hereafter appear. A is the frame of the
machine B is the feed table or support for the paper having a pile of sheets
thereon, and is secured to nuts C, which have extended arms a moving upon
friction rollers in recesses or grooves formed in or on the frame (Figs. 1 and 4),
and said nuts are actuated by the screws D. which are driven simultaneously by
the connecting shafts D2, and the bevel gears' D E is the driving shaft, upon
which are placed the friction wheels F, by which the sheet paper is impelled
forward when the smaller friction rolls are made to press the sheet of papar
against them (see Figs. 3 and 6); G (Fig. 2) is the main shaft on which are placed
the several cams that actuate the various arms or levers; H is a sprocket wheel
on the shaft G, to which power is communicated by means of a chain e from a
smaller sprocket wheel I upon the driving shaft E (Fig. 5).
J and are tape rolls with grooves cut in each, the relative position of which
is such as to carry the paper upon the tapes or cords passing from the feeder in a
line diverging from a right line against the adjustable registering guide K, which
is fastened to the tape table L by a bolt (Fig. 5), which permits its position to
be changed at will, the table being slotted at right angles to its length. The tape
rolls are revolved by means of a belt 7 passing around the roll J and grooved
pulley upon the main shaft G (Figs: 2 and 5): M is a movable regulating roll
having its bearings in one end of the arms N, the other end of said arms being
pinned to an independent shaft O, to which a reciprocating motion is imparted by
means of the cam coming in contact with a cam roll on the end of a curved
lever b', which is also pinned to the shaft (, as shewn at Fig. 2 and Fig. 3. This
roll is varied to permit the paper to pass without opposition over the tape roll J,
and is then brought to bear against the surface of the paper; thereby regulating its
forward motion, and imparting to it the same speed as the tapes, affording a better
opportunity for perfect registration. P. indicates guides to steady and direct the
paper when fed from the pile or table to the tapes. a³ (Figs. 3, 4, 5, and 6) is an
arm to which the pressure roll 72 is attached, and is used as a holding device
during the operation of buckling: it is attached to the pivoted arm or lever S. by
the bolt or pivot d¹, the roll 2 being held upon the surface of the paper by its

page_text: weight. a is the arm which holds the rubbing pad 3, and this with the holding
device, consisting of the arm a³ and roll 32, form the buckling device; it is also
attached to the pivoted arm or lever S by the bolt or pivot d. Upon its upper
side is secured a spring f', which extends from the end on which the rubbing
pad 3 is held toward the other end of the arm, and past the bolt d'. Increased
pressure of the pad 63 upon the paper is obtained by means of the thumb screw e
and a reduced pressure by the use of e', both of which are inserted in the arm a³,
and against the bottom of which the spring is permitted to press, as the case may
require. The lever S is pivoted to the frame A at 4 (Figs. 2, 3, and 4) by the
stud 9 reciprocating motion is imparted through the cam roll by the double
acting cam and spring . The other end of the lever S is slotted, as at f; to
admit of a variation of the distance between the roll 2 and the rubbing pad 63.
With thick paper the distance should be increased, and per contra with very thin
paper. With heavy paper it is also necessary to apply increased pressure upon 63
by the thumb screw e², and with very light paper to diminish it by the thumb
screw e to insure the separation of but one sheet. By pivoting the arms S, a³,
and a I am enabled to apply an unvarying pressure upon the surface of the paper.
Upon the inner side of the arm is a lug or projection f, seen on Fig. 5, which
extends under the arm . against which the rod or bar (Figs. 4 and 6) strikes
when it becomes necessary to raise the buckling device from the pile of paper to
remove the sheet. The rod or bar is pivoted at j' to an arm 7 working upon
the shaft p; it is slotted at P to permit its moving up and down, and is held in
place by a stud screwed into the frame through the slot ; it is actuated by the
camp through the cam roll 2 (Fig. 3). T is a horizontally reciprocating
separating plate pivoted at d (Figs. 3, 4, and 5) to the two arms R, which arc
pinned to the shaft p, and it obtains a horizontal reciprocating motion by means
of the arm R and cam U; it has also an upward and downward movement, which
is obtained by the lever being actuated by the cam U' on the main shaft G
(Fig. 4), and striking or coming in contact with the lever O of the separating
plate. The object of this vertical motion is to enable the buckling device, to fold
or buckle the paper while the separating blade is receding from its advanced
position without pressing upon the fold of the paper and retarding the operation.
It is also raised when being advanced to prevent the point of the blade from
penetrating or disturbing the remaining sheets. On the shaft are small rolls or
frictional rings, which are brought in contact with the other side of the sheet of
paper about being removed from the pile by the forward movement of the
vibrating armis R, and pressing it firmly against the larger rolls F, which are
constantly in motion motion being in this way communicated to them they aid
in delivering the sheet to the tapes. At t is shown a slot or opening in the
separating plate T, into which the pivoted toe m attached to the sliding barn of
the stop motion falls when no paper is interposed between the toe and said plate
to prevent it. The barn is slotted at, and on its upper side has an inclined or
wedged shaped projection (Fig. 3). Upon being forced backward by the toe m
engaging with the separating plate T, the bar m in the slotted piece n¹ is raised
by the inclined surface of and disengaged from the shoulder 6 (Fig. 1), which
previously secured it, and by the pressure of the spring it is forced outward,
throwing the lever m² (Fig. 8) far enough to disconnect the sections V and V1 of
the clutch and thus stop the machine. The slotted bar when not forced from
its position is held in place by a spring w (Fig. 3). C is an adjustable rod, upon
which are placed the adjustable paper guards and can be lengthened. and
shortened at will by loosening the thumb screw g (Fig. 2). O' is a disc, upon the
under side of which is formed a ratchet, and is keyed to the upper end of one of
the screws D, through which power is communicated to operate the feed, table.
Sis a pawl weighted at one end to keep the other continually engaged with
the ratchet, and is pivoted by a stud upon the upper end of a right angled
lever $2.
$ is a right angled lever secured to the side of the frame A by the stud W upon

page_text: which it oscillates, having at its lower end a cam roll K it is actuated by the
cam 0²; upon one side it has a projection, lug or arm, one side of which is formed
at an angle with a right line running vertically through the centre of the stud
upon which it is pivoted as at . S is another right angled arm secured to a
shaft (Fig. 7) which extends entirely through the machine; at the end of the
short arm it has a cam roll (Figs. 7 and 1), through which motion is com-
municated by the cam 02 at its other end is pivoted a link t', which is also
pivoted at 2 (Fig. 7) to the horizontal bar U, which extends through both sides of
the frame, the other end of the bar U is pivoted to a link ', and connection is
made with the shaft by means of a lever corresponding with the lever S³
without its short arm. Y (Figs. 1 and 7) is a compensating or regulating lifting
arm or foot, which is attached to the cross-bar U by a screw near each side, one
of which screws serves as a pivot, the other passes through a slot and permits the
arm or foot to adjust itself to the unevenness of the surface of the paper; y
(Figs. 2 and 7) is a pin in the lever S3, which serves as a stop to determine the
backward motion of the lever S², the position of. which is determined by the
position of the feed table or pile of paper. As the paper is taken from the surface
of the pile, the arm or foot Yadjusts itself to the remaining paper, consequently
the position of the long arm of the lever S3 is also regulated, permitting that part
of the lever S2 below the projection or lug to operate on the pin y, and in
consequence the pawl S¹ engages a greater or less number of teeth in the ratchet
of the disc 01 as the oscillation of the arm $2 is increased or diminished. Z. Z, are
plates against which the front edge of the paper is placed; a graduated scale q is
placed by the side of the feed table or support for paper as a matter of convenience
in adjusting the machine, when a known quantity of paper is to be placed upon
the feed table. Having described the various pieces and parts of the machine its
operation is as follows:-The pawl S¹ is lowered and the disc 0' is revolved in the
direction of the slant of the teeth of the ratchet, motion is thus imparted to the
screws D which engage with the nuts C and lower the table B attached thereto.
The pile of paper is then placed upon said table, the front edge placed against the
guides Z, Z, the right side of the paper being placed against other guides to one
of which the scale Q is attached, shown in Fig. 1, and by having straight edges
upon two sides of the feed table the paper can always be fed with accuracy. The
disc is now revolved in the opposite direction until the top sheet of the pile of
paper is even with the top mark of the scale Q or bottom of the compensating or
regulating arm or foot Y. The guards,, are then shoved down behind the
paper to prevent its being forced out of place by the action of the rubbing or
buckling device. Should it become necessary on account of the width of the paper
the rod (Figs. 4 and 5) to which the guards, 5, are secured may be placed in
or out to conform to the size of the paper, the rod passing through a support y¹,
to which it is fastened when required by a thumb screw. Power now being applied
to the wheel of the driving shaft E it is communicated to the main shaft G, upon
which are placed the cams that actuate the various parts by the sprocket wheels
and chain; the rubbing or buckling device presses upon the surface of the paper,
and with a reciprocating movement, which is preferably repeated two or more
times to insure the separation of the sheet, rubs the sheet backward from the edge
of the pile, and permits the blade T to press upon the remaining sheets or pile.
Upon the receding of the buckling device that part of the sheet which was arched
by the rubber or frictional surface is drawn toward the edge of the pile, and not
being permitted to occupy its former position on account of the presence of the
separating blade T, it is forced upon the surface of said blade, which by the
operating mechanism is now introduced further beneath the said sheet, the point
having an upward movement as it advances to prevent penetrating the remaining
paper in case there should be any unevenness of its surface, the reciprocating arms
of the buckling device being raised by the upward movement of the rod i, and the
regulating arm or foot Y being raised by levers $3 and cam 12 (Figs. 2 and 7); the
separating blade and the small rolls d³ continue to advance under the sheet until

page_text: the rolls, d approach sufficiently near to the large frictional rolls F upon the
shaft E to press the sheet against them, they being constantly in motion co-operate
with the smaller rolls to remove the sheet from the pile and deliver it on the
tapes.
The regulating arm or foot Y is now lowered upon the paper and the separating
blade or plate recedes with its point elevated to clear the next sheet, which is now
being buckled or arched by the rubbing device, and is again pressed upon the pile
of paper after a part of the sheet is removed from the edge of the pile, when the
movements above described are repeated.
The sheet previously removed is carried by the endless tapes on the rolls J, J,
diagonally toward and against the side of the registering board or guide K (Figs. 2,
3, and 5) to its required destination. As the sheets are removed from the pile the
regulating roll M, which was previously raised to admit of the free passage of the
paper, is lowered and impinges upon the paper, receiving its motion from contact
with the tapes or the roll J. By this means the forward motion of the paper is
regulated, and it is carried from the feeder at the same speed given to the tapes,
which aids in obtaining a more perfect register of the paper. The roll can be made to
press upon the moving paper at any time by adjusting cam ², which actuates it
upon the main shaft G, it being secured thereto by a set screw.
As the paper is removed from the pile the adjusting arm or foot Y drops, and in
consequence the long arm of the lever S is regulated, and the relative position of
the pin is changed, thus permitting the end of the arm S2, to which the pawl is
attached, to describe a greater or less are of a circle, allowing the said pawl to
engage more or less teeth in the ratchet of the disc 01, and by turning the screws D
to move automatically the feed table and paper to the proper position. It is evident
that a ratchet clamp may be used with a smooth grooved dise without teeth in lieu
of the toothed ratchet shown in the Drawing with the same result.
In case of a failure or omission to pass a sheet of paper from the pile or feed
table. the separating blade T moving forward permits the pivoted point of the toe m
to drop into or engage with said blade or plate T (Figs. 3 and 5), and being forced
backwards pushes the slotted barn, and by means of its upper wedged shape
surface raises the cross bar m² above its shoulder, when by the pressure of a
spring it is forced outward, and throwing the pivoted lever m² in a position to
disengage the sections V and V₁ of the clutch shown at Fig. 8, and stops the
operation of the machine.
