Improvements in Automatic Paper Feeding Machines for Printing
Presses and the like.
A communication from abroad by THOMAS A. BRIGGS, of Arlington, in the State
of Massachusetts, United States of America, Machinist.
I, JOHN MAGRATH KELLY, of 1 Charlotte Street, Bedford Square, in the
County of Middlesex, Merchant, do hereby declare the nature of this invention
to be as follows:-
This invention relates to a feeding machine, in which it is possible to automatically
feed sheets, singly, from a pile of sheets of paper to a printing press or similar
machine. Various devices have heretofore been employed for this purpose, but
none it is believed operate upon the same plan and perform the work in so simple
and effective a way as the machine herein described.
In the drawings like letters of reference indicate corresponding parts.
Fig. 1 represents a plan view of the machine, Fig. 2 an end elevation, Fig. 3 a
sectional elevation on line R, R, of Fig. 1, and Fig. 4 is an enlarged detail view of
the feed roll and the means for actuating the same.
A represents the frame of the machine. B a vertically movable table or bed,
upon which the paper is placed. C is a clamp arranged to move back and forth in
slot D of the frame A, the bottom of clamp C being held in place by a pin which
passes into one of the holes D' in the sides of the slot. The clamp is arranged to
hold the sheets of paper in place, the top of clamp projecting through a slot in the
table B as shewn. The pile of sheets of paper P are beld from moving backward
by the clamp C and from moving forward by the fingers z of the machine; the
guides moving in slot 23 and secured by thumb screws 2 hold the papers at the
side. One or more fingers z placed in the front of the frame rest upon the top sheet.
The fingers z are preferably formed as shewn with a round head, one side of head
overlapping and pressing upon the top of the pile of sheets; to the said head of
the finger is attached a stem z Fig. 3, which slides up and down in a groove
formed in the frame. The groove is made a little out of the perpendicular, the top
being nearer the front of the paper than the bottom, so that the head of the finger
will tend to press downward upon the top sheet of the pile of paper; the fingers
are free to move and are held in place by their weight upon the paper. Any
number of fingers may be employed as desired or one long finger may be used, but
that described is preferred as well as the manner of inserting and operating as
shewn although they may be varied in form and manner of adjustment and still
work quite efficiently. The manner in which they aid in holding and delivering
the paper will be hereinafter described. The bed B upon which the paper is piled
is arranged to be automatically raised as the sheets are taken off one at a time from
the top of the pile as will also be hereinafter explained.
Referring to Fig. 2, a is a segmental gear wheel attached to the shaft o. The
power is applied by suitable means at a, which imparts an oscillatory motion to
the segmental gear wheel a. The teeth of wheel a meshes with gear wheel b¹ which
is journalled to stud b, the stud being secured to frame A. The gear wheel c is
also journalled to stud and turns by gear wheel 6' to which it is attached, meshing
into pinion or gear wheel e, the latter being loosely journalled on shaft q. A
pulley d is attached to the shaft 9 and has upon one side the pawls d¹ d¹ working in
gear wheel e.
Attached to the segmental gear wheel a is the arm connecting
with the socket g and adjustably secured therein by set screw g'. The socket g is

page_text: jointed to the piece which is loosely journalled on shaft as indicated by dotted
lines in Fig. 2. The piece h at one end has the pawl h¹. On the shaft r is placed
the hollow wheel k loosely journalled thereon and inside of wheel k is placed the
ratchet as shewn in Fig. 2.
In the drawing part of wheel k is shown as broken away. The periphery of
wheel k is entire except at near the points j and where the periphery is left open
for the purpose of permitting pawls and n to engage the teeth of ratchet wheel
for the purpose hereinafter specified. The ratchet is secured to shaft r.
Pawl n
is formed preferably weighted as by weight n².
The arm m is secured to the frame A at m³, one end of arm m being slotted to
slip over the pin k¹ fixed in wheel k; the other end of arm m is bent so as to be
conveniently secured to sleeve m², Fig. 1. Said sleeve m² surrounds the shaft m³
and extends to fixture m' also as shewn in Fig. 1.
Upon the opposite end of the machine are placed the segmental gear wheel t,
(the same being shewn by dotted lines Fig. 3) the rack bar u with teeth and other
operative parts. Segment t is secured to shaft o. The teeth of bar u mesh with
the teeth of segment and the said bar u operates shaft m³ by means of gear
wheel m. Upon the shaft r are placed gears r' and which mesh in teeth of
vertical racks H placed at each end of frame A for the purpose of raising the
table B and to which they are attached the operation will be readily understood
by referring to Fig. 3. Midway on shaft m³ is placed the gear wheel m³, which is
secured thereto. The gear me meshes into rack bar. The rack bar x² slides
longitudinally in, and is guided by a sleeve m² formed on the bottom of the
fixture me. The said fixture m is attached to or a part of sleeve m² and moves
with it on shaft m³. The movement of the fixture me and loose sleeve m* of course
permits of an up and down motion of the end of bar and is important as a
part of a regulating principle involved in the present invention. To the front end
of bar is secured the yoke to the ends of which is journaled the arbor y³ which
is at right angles to the rack bar and to this arbor are rigidly secured rollers y
and y' preferably faced with rubber on their peripheries to afford a frictional hold
for said rollers on the underlying sheet of paper for the purpose hereinafter
described. To the arbor between the aforesaid rollers is also firmly secured a
ratchet wheel y³, and to the yoke 2 at its juncture with the end of the rack ² is
connected a pawl y which is formed with a head by which it rides on the periphery
of the ratchet wheel y'. The head of said pawl is beveled on its front to allow it
to slide over the teeth of the ratchet wheel and is formed with an abrupt rear
shoulder by which it engages the said teeth. To the yoke adjacent to the end
of the rack is also pivoted a dog y' which is provided with a tripping finger y*.
This dog is adapted to fall with its free end onto the periphery of the ratchet
wheel and has said end terminating with a face adapted to engage the teeth of
the ratchet wheel so as to prevent said wheel from rotating toward the rack r².
Over the rack and parallel therewith is a rod x which is mounted adjustable
in a sleeve or barrel formed on the fixture m' and is retained in its adjusted position
by a set screw. The free end of said rod has affixed to it a disc or detent a¹
which is in such a position as to cause the dog to come in contact therewith
during the rearward movement of the rack and become thereby thrown over upon
the ratchet wheely. In said movement the tripping finger y falls against the back
of the disc or detenta as shewn in Fig. 4 and in the reverse movement of the
rack the contact of said finger with the disc causes the finger to be swung back
and down and thereby raise the dog y³ from the ratchet wheel and to a rearwardly
inclined position in which it is retained by gravity.
By adjusting the rod e so as to hold the detent ' at different points in the path
of the dog y³ said dog is adapted to operate on paper of different sizes.
The shaft y acts as a roll, or a roll may be affixed on shaft to aid in delivery of
the sheets of paper.
E is a table upon which the severed sheets of paper are delivered, and of a roll
placed on an arbor or shaft running in bearings and driven by gears from

page_text: shaft q as shewn in Fig. 1. The roll v projects above the surface of table and
is preferably placed diagonally as shewn for the purpose of carrying the sheet Pi
down against the projecting guides E' E' thereby always presenting the sheet of
paper properly and true to be seized by the finger G or any similar device of the
printing or other machine.
F represents a type cylinder or wheel to which said sheets are separately
delivered. In Fig. 1 the table E is shown broken in two parts for convenience of
illustration. The guides E' E' are adjustable in slots E' E' and are secured in
position in any convenient manner.
Having now described the several parts of the machine, its operation will be
explained. The pile of sheets of paper P are placed on the movable bed B and
secured at the back by clamp C the front being held by the frame of the machine,
the guides being properly adjusted and secured. The fingers Z by their heads
rest upon the top sheet P' of the pile. Now when power applied to segmental
gear wheel y at a² said gear receives an oscillatory motion which is transmitted to
the shafts o and m³ which latter imparts a reciprocating motion to the rack
bar by means of the pinion or gear wheel m. In the backward movement of
said rack-bar the rollers y' and y' are drawn back upon the top of the paper Pl.
During this movement the rollers are free to rotate upon the paper owing to the
capability of the pawl y² to slip over the teeth of the ratchet wheel y. But in
the latter part of the said movement of the rack the dog y³ comes in contact with
the disc and is thereby pushed forward and finally caused to drop by gravity
into engagement with the ratchet wheel. The tripping finger y' of said dog lying
then at the back of the disc. The engagement of the dog with the ratchet wheel
prevents the rollers and y' from turning and in the farther backward movement
of the rack-bar the tripping finger is carried some distance away from the disc
while the rollers act as drags and pull the front part of the top-sheet of paper back
from under the fingers while the back portion of said sheet is held by the
clamp C. As soon as the paper has been withdrawn from under the fingers z as
aforesaid the fingers drop by gravity upon the next underlying sheet and are thus
in position to allow the top sheet. to slide over the top of the fingers. In the
reverse movement of the rack the dog y loses its hold on the ratchet-wheel and
locks said ratchet wheel and rollers y' and y' and causes the lutter to push the top
sheet of paper forward over the fingers, and upon the roller or arbor q by
means of which the said sheet of paper is carried to the table E and thence by
roll to the printing or other machine, in which latter motion the paper is carried
with one of its side edges against the guides E2 E2 which serve to direct the
in its travel. In this latter movement of the rack the tripping finger y strikes
the disc and thereby throws the dog back sufficient to rest by gravity in a
rearwardly inclined position as represented in Fig. 3 of the drawing. The succesive
sheets are released from the fingers z in the same manner and delivered upon the
table E.
paper
The bar being connected with the fixture m' and the fixture with the sleeve m'
acts as a regulator to set in operation the mechanism for raising the bed B. As the
sheets Pare removed from the top of the pile the end of bar e will fall correspondingly
which will cause the sleeve m² to turn, thus causing the outer end of arm m to be raised,
while the other end of arm m will be lowered, thus depressing the stud attached to
pulley and causing pulley k to be slightly turned, sufficiently to enable pawl
to engage the ratchet wheel j and as pawl is actuated by arm the ratchet
wheel will turn shaft r and the gears will operate with the racks H H con-
nected with bed B and the bed will be raised, of course carrying upward the pile
of paper P placed thereon. When the bed shall have been sufficiently raised, the
the movement of
bar still acting as a regulator will automatically reverse
sleeve m² and the arm m will turn back the pulley or shield k so that
will be disengaged and the upward movement of the bed B will cease.
will be held in position by the pawl n engaging the ratchet wheel j'.
paper is removed from the top of the pile, the bed will be automatically
the pawl h¹
The bed B
Thus as the
raised and

page_text: the top sheet will rest under fingers z and always be held in place ready for
delivery by the mechanism already described.
The particular method consisting of the racks H H and gears for raising
the bed B need not be necessarily used, as screws or other well known means could
be employed. The stem of finger indicated by is preferably arranged in a
slot or groove out of the perpendicular as shewn in Fig. 3, so that the edge of the
head which overlaps the paper will always press upon the top surface of the upper
sheet. The weight of the finger is sufficient to keep it in place and hold down the
edge of the sheet. One or more fingers may be. eniployed or one long continuous
finger with a continuous end 2, or two or more narrow ends, may be used if desired.
The arm.³ may be larger or may extend across the machine and more than two
rolls yy may be employed. Instead of one rack bar a and one rod x a number
may be used and could be attached to sleeve m² with several fixtures m': in the
latter case the sleeve m³ would preferably extend the whole width of the machine
on arbor m³.
The invention is not confined to the exact details of construction shown as it is
evident that many mechanical changes may be made without departing from the
spirit of my invention.
It will be observed that the operation of removing a sheet of paper from the top
of the pile consists chiefly in rolling the wheels y y' back upon the paper, then
stopping the motion of wheels y y' and dragging the said wheels sufficiently
backward to release the sheet from the fingers, the back of the sheet being
meanwhile firmly held at the back of the clamp C, then the wheels y' are pushed
forward dragging or pushing the sheet over the fingers which, meanwhile, have
dropped upon the next sheet, the sheet passing over the roll q and being thence
carried away substantially as hereinbefore described.
This method of releasing and removing the severed sheets from a pile is original
with the present invention and has many advantages over other methods known to
me or heretofore employed.
The method of automatically regulating the raising of the bed, herein set forth,
is also peculiar to the present invention as the height of the top of the pile of
sheets is gauged at the front near the retaining fingers, this is important. The
same mechanism that releases and removes the sheets also automatically regulates
the raising of the bed B and the consequent height of the top of the pile in
relation to the fingers and delivery roll g. This combination is peculiarly valuable
in operation.

the County of Middlesex, but now of 20 Cheapside in the City of London,
Merchant, 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 relates to a feeding machine, in which it is possible to auto-

A represents the frame of the machine.
B a vertically movable table or bed,
upon which the paper is placed. C is a clamp arranged to move back and forth in
slot D of the frame A, the bottom of clamp C being held in place by a pin. The
clamp which passes into one of the holes D' in the sides of the slot is arranged to
hold the sheets of paper in place, the top of clamp projecting through a slot in
the table B as shown. The pile of sheets of paper Pare held from moving back-
ward by the clamp C and from moving forward by the finger of the machine; the
guides moving in slot ³ and secured by thumb screws hold the papers at the
side. One or more fingers placed in the front of the frame rest upon the top
sheet. The fingers z are preferably formed as shown with a round head, one side
of head overlapping and pressing upon the top of the pile of sheets; to the said
head of the finger is attached a stem 2, Fig. 3, which slides up and down in a
groove formed in the frame. The groove is made a little out of the perpendicular,
the top being nearer the front of the paper than the bottom, so that the head of the

Referring to Fig. 2, a is a segmental gear wheel attached to the shaft o. The
power is applied by suitable means at a, which imparts an oscillatory motion to the
segmental gear-wheel a. The teeth of wheel a meshes with gear wheel which
is journalled to stud b, the stud being secured to frame A. The gear wheel e is
also journaled to stud and turns by gear wheel to which it is attached, meshing
into pinion or gear wheel e, the latter being loosely journaled on shaft g.
pulley d is attached to the shaft g and has upon one side the pawls d' d' working in
gear wheel e.
Attached to the segmental gear wheel a is the arm connecting with
the socket g and adjustably secured therein by set screw 9. The socket y is jointed
to the piece which is loosely journaled on shaft r as indicated by dotted lines in
Fig. 2.
The piece at one end has the pawl h. On the shaft is placed the
hollow wheel k loosely journaled thereon and inside of wheel k is placed the
ratchet as shown in Fig. 2.
In the drawing part of wheel k is shown as broken away. The periphery of
wheel is entire except at near the points j and where the periphery is left open
for the purpose of permitting pawls and n to engage the teeth of ratchet wheel j¹
for the purpose hereinafter specified. The ratchet jis secured to shaft r.
Pawl n
is formed preferably weighted as by weight 2. The arm m is secured to the
frame A at m', one end of arm m being slotted to slip over the pin A¹ fixed in
wheel; the other end of arm m is bent so as to be conveniently secured to
sleeve m², Fig. 1. Said sleeve m' surrounds the shaft m³ and extends to fixture m
also as shown in Fig. 1.
Upon the opposite end of the machine are placed the segmental gear wheel t, (the
same being shown by dotted lines Fig. 3) the rack bar u with teeth and other
operative parts. Segment is secured to shaft o. The teeth of bar mesh with
the teeth of segment t and the said bar operates shaft m³ by means of gear
wheel m. Upon the shaft r are placed gears and which mesh in teeth of

page_text: vertical racks H placed at each end of frame A for the purpose of raising the
table B and to which they are attached the operation will be readily understood
by referring to Fig. 3. Midway on shaft m³ is placed the gear wheel m³, which is
secured thereto. The gear mmeshes into rack bar ². The rack bar ² slides
longitudinally in and is guided by a sleeve m formed on the bottom of the
fixture me. The said fixture m is attached to or a part of sleeve m³ and moves
with it on shaft m³. The movement of the fixture m and loose sleeve m³ of course
permits of an up and down motion of the end of bar and is important as a
part of a regulating principle involved in the present invention. To the front end
of bar is secured the yoke to the ends of which is journaled the arbor y which
is at right angles to the rack bar and to this arbor are rigidly secured rollers y
and y preferably faced with rubber on their peripheries to afford a frictional hold
for said rollers on the underlying sheet of paper for the purpose hereinafter
described. To the arbor y between the aforesaid rollers is also firmly secured a
ratchet wheel, and to the yoke at its juncture with the end of the rack.² is
connected a pawl y² which is formed with a head by which it rides on the periphery
of the ratchet wheel y. The head of said pawl is bevelled on its front to allow it
to slide over the teeth of the ratchet wheel and is formed with an abrupt rear
shoulder by which it engages the said teeth. To the yoke adjacent to the end of
the rack is also pivoted a dog y3 which is provided with a tripping finger y*.
This dog is adapted to fall with its free end onto the periphery of the ratchet
wheely and has said end terminating with a face adapted to engage the teeth of
the ratchet wheel so as to prevent said wheel from rotating toward the rack ².
Over the rack and parallel therewith is a rod which is mounted adjustable
in a sleeve or barrel formed on the fixture me and is retained in its adjusted
position by a set screw a. The free end of said rod has affixed to it a disc or
detent which is in such a position as to cause the dog y³ to come in contact
therewith during the rearward movement of the rack and become thereby thrown
over upon the ratchet wheely. In said movement the tripping finger y falls
against the back of the disc or detent as shown in Fig. 4 and in the reverse
movement of the rack a² the contact of said finger with the disc causes the finger
to be swung back and down and thereby raise the dog y³ from the ratchet wheel
and to a rearwardly inclined position in which it is retained by gravity.
By adjusting the rod a so as to hold the detent r¹ at different points in the path
of the dog y said dog is adapted to operate on paper of different sizes.
The shaft g acts as a roll or a roll may be affixed on shaft to aid in delivery of
the sheets of paper.
E is a table upon which the severed sheets of paper are delivered, and v* a roll
placed on an arbor or shaft running in bearings and driven by gears_from
shaft 9 as shown in Fig. 1. The roll v projects above the surface of table E and
is preferably placed diagonally as shown for the purpose of carrying the sheet P¹
down against the projecting guides E' E' thereby always presenting the sheet of
paper properly and true to be seized by the finger G or any similar device of the
printing or other machine.
F represents a type cylinder or wheel to which said sheets are separately
delivered. In Fig. 1 the table E is shown broken in two parts for convenience of
illustration. The guides E' E' are adjustable in slots E E' and are secured in
position in any convenient manner.
Having now described the several parts of the machine, its operation will be
explained. The pile of sheets of paper P are placed on the movable bed B and
secured at the back by clamp C the front being held by the frame of the machine,
the guides being properly adjusted and secured. The fingers by their heads
rest upon the top sheet P' of the pile. Now when power is applied to segmental
gear wheel y at a said gear receives an oscillatory motion which is transmitted to
the shafts og and m³ which latter imparts a reciprocating motion to the rack
bar by means of the pinion or gear wheel m³. In the backward movement
of said rack-bar the rollers y and y' are drawn back upon the top of the

page_text: 2
paper P. During this movement the rollers are free to rotate upon the paper
owing to the capability of the pawl y² to slip over the teeth of the ratchet wheely.
But in the latter part of the said movement of the rack the dog comes in
contact with the disc and is thereby pushed forward and finally caused to drop
by gravity into engagement with the ratchet wheel. The tripping finger y* of said
dog lying then at the back of the disc. The engagement of the dog with the
ratchet-wheel prevents the rollers y and y' from turning and in the farther
backward movement of the rack-bar the tripping finger is carried some distance
away from the disc while the rollers act as drags and pull the front part of the top
sheet of paper back from under the fingers while the back portion of said sheet
is held by the clamp C. As soon as the paper has been withdrawn from under the
fingers as aforesaid the fingers drop by gravity upon the next underlying sheet
and are thus in position to allow the top sheet to slide over the top of the fingers.
In the reverse movement of the rack the dog y loses its hold on the ratchet-
wheel and locks said ratchet wheel and rollers and y' and causes the latter to
push the top sheet of paper forward over the fingers, and upon the roller or
arbor by means of which the said sheet of paper is carried to the table E and
thence by roll to the printing or other machine, in which latter motion the paper is
carried with one of its side edges against the guides E E2 which serve to direct the
paper in its travel. In this latter movement of the rack the tripping finger y strikes
the disc and thereby throws the dog y' back sufficient to rest by gravity in a
rearwardly inclined position as represented in Fig. 3 of the drawing. The
successive sheets are released from the fingers in the same manner and delivered
upon the table E.

"
The bar being connected with the fixture me and the fixture with the sleeve m²
acts as a regulator to set in operation the mechanism for raising the bed B. As
the sheets P are removed from the top of the pile the end of bar will fall
correspondingly which will cause the sleeve m² to turn, thus causing the outer end
of arni m to be raised, while the other end of arm m will be lowered, thus
depressing the stud attached to pulley k and causing pulley k to be slightly
turned, sufficiently to enable pawl ' to engage the ratchet wheel j' and as pawl h
is actuated by arm the ratchet wheel will turn shaft and the gears will
operate with the racks H H connected with bed B and the bed will be raised, of
course carrying upward the pile of paper P placed thereon. When the bed shall
have been sufficiently raised the bare still acting as a regulator will automatically
reverse the movement of sleeve m and the arm m will turn back the pulley or
shield k so that the pawl h will be disengaged and the upward movement of the
bed B will cease. The bed B will be held in position by the pawl n engaging the
ratchet wheel j. Thus as the paper is removed from the top of the pile, the bed
will be automatically raised and the top sheet will rest under fingers 2 and always
be held in place ready for delivery by the mechanism already described.
=
The particular method consisting of the racks H H and gears ¹² for raising the
bed B need not be necessarily used as screws or other well known means could be
employed. The stem of finger indicated by ¹ is preferably arranged in a slot or
groove out of the perpendicular as shown in Figure 3, so that the edge of the head
which overlaps the paper will always press upon the top surface of the upper
sheet. The weight of the finger is sufficient to keep it in place and hold down
the edge of the sheet. One or more fingers may be employed or one long
continuous finger with a continuous end z or two or more narrow ends may be used
if desired. The arm may be larger or may extend across the machine and
more than two rolls y may be employed. Instead of one rack bar and one
rod a number may be used and could be attached to sleeve m² with several
fixtures m; in the latter case the sleeve m² would preferably extend the whole
width of the machine on arbor m³.
The invention is not confined to the exact details of construction shown as it
is evident that many mechanical changes may be made without departing from
the spirit of the invention.

page_text: It will be observed that the operation of removing a sheet of paper from the
top of the pile consists chiefly in rolling the wheels y y' back upon the paper,
then stopping the motion of wheels y and dragging the said wheels sufficiently
backward to release the sheet from the fingers the back of the sheet being
meanwhile firmly held at the back by the clamp C then the wheels y y' are
pushed forward dragging or pushing the sheet over the fingers z which, mean-
while, have dropped upon the next sheet, the sheet passing over the roll q and
being thence carried away substantially as herein before described.
This method of releasing and removing the severed sheets from a pile is
original with the present invention and has many advantages over other methods
known to me or heretofore employed.
The method of automatically regulating the raising of the bed, herein set
forth, is also peculiar to the present invention as the height of the top of the
pile of sheets is gauged at the front near the retaining fingers, this is important.
The same mechanism that releases and removes the sheets also automatically
regulates the raising of the bed B and the consequent beight of the top of the
pile in relation to the fingers z and delivery roll g. This combination is peculiarly
valuable in operation.

invention as communicated to me by my foreign correspondent and in what manner
the same is to be performed, I declare that what I claim is :-
1. In combination with the paper supporting table, and a clamp holding the
paper in a pile upon said table, a reciprocating bar carrying rollers back and
forth upon the paper, a pawl and ratchet locking said rollers in one direction,
and a dog locking the rollers temporarily in the opposite direction during the
reciprocating movement of the aforesaid bar, as set forth.
2. In combination with the paper-supporting table and a clamp holding the
paper piled on said table, a reciprocating bar moving parallel with the line of
