I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOr feeding
SHEETS OF PAPER TO PRINTING, FOLDING AND OTHER MACHINES to be as
follows:-
"
This Invention relates to an improved machine for feeding sheets of paper, one
after another, to ruling, folding or calendering machines, printing presses, and
other machines which are supplied with sheets of paper, and more particularly to
a machine of this kind in which the pile of paper is supported on a table which is
automatically raised as the sheets of paper are successively fed from the top of the
pile by the buckling and feeding devices and placed within reach of the feed rollers
or tapes which move the sheets onward one after the other. The object of this
invention is to simplify the construction of the machine and to render it more
efficient and reliable in its operation.
of
I will first describe the construction of a machine suitable for use in connection
with ruling and similar machines. The said machine is provided with side frames
connected by cross stays. The said frames carry a feed table upon which the pile
paper is placed. The said feed table is secured to supports which are provided
near their outer ends with screw nuts and upright extensions having rollers, which
rollers run in vertical grooves formed on the inner sides of the side frames, whereby
the feed table is guided in its vertical movements. Vertical screws work in the
screw nuts secured to the feed table, and are held against lengthwise movement in
bearings secured to the side frames. A hand wheel is secured to the upper end of
one of the feed screws, and is provided on its under side with an annular ratchet
rim. The lower ends of the feed screws are connected by a horizontal shaft and
bevel wheels, so that both feed screws are actuated simultaneously.
Stationary vertical guides are arranged upon cross bars secured to the side
frames. The said guides are placed closely against the front end of the feed table,

page_text: '
so as to support the front of the pile of paper on the table, and prevent the same
from tipping or tilting forwardly. Similar guides may also be arranged adjacent
to the table and the outer side of the pile of paper on the same,
Outwardly projecting arms or brackets are secured at their inner ends to the
side frames, and provided with longitudinal slots. An adjustable vertical guide is
secured at its ends to the said brackets by means of thumb screws passing through
the slots of the brackets. By this means the adjustable guide can be adjusted
back wardly and forwardly for different sized piles of sheets placed upon the table.
The upper of the two brackets also serves to support the buckling mechanism when
the table is lowered to receive a fresh supply of paper.
The horizontal driving shaft is arranged transversely of the machine and
supported in bearings in the side frames. A counter-shaft is arranged below the
driving shaft and parallel with the same. Motion is transmitted from the driving
shaft by a train of gear wheels in such manner that the speed of the counter shaft
can be increased or reduced by changing the relative sizes of the gear wheels.
A clutch coupling is provided whereby the driving pulley can be thrown in and
out of gear as desired.
A horizontal rock shaft is arranged at right angles to the driving and counter
shafts and is supported in bearings formed on one of the side frames. A similar
rock shaft is also arranged parallel with the first rock shaft and above the same,
and supported in bearings formed on one of the side frames. A strap or link
connects the two rock shafts near their outer ends, so as to prevent the same from
springing or bending when they are extended.
The said strap is held from lateral displacement by a finger and a collar which
are secured to the second rock shaft on opposite sides of the said strap.
An upwardly extending arm secured to one of the rock shafts has attached to
its upper end the buckling device.
An elbow lever is pivotted to the inner side of one of the side frames by means
of a pivot bolt. A second lever is secured to the first rock shaft by means of a
set screw.
The second lever extends inwardly through an elongated opening or
slot formed in one of the side frames, whereby the lever and the first rock shaft
are held from lateral displacement. The set screw of the second lever engages in
a longitudinal slot or groove formed in the first rock shaft so that by loosening the
screw the said rock shaft may be moved laterally in its bearings to adjust the
upwardly extending arm and buckling device attached thereto, to the different
sizes of sheets of paper.. A vertical rod connects the inner end of the second lever
with the horizontal arm of the elbow lever. The vertical arm of the elbow lever
is bifurcated to engage over a cam secured to the countershaft whereby motion is
imparted to the elbow lever vertical connecting rod, second lever, and the first
rock shaft.
A finger is secured to the end of the second rock-shaft by a set screw, and rests
with its free end upon the corner of the pile of paper adjacent to the buckling
device. The said finger is held down upon the pile of paper by means of an arm
which is secured to the second rock-shaft by a set-screw and a spiral spring, which
latter is secured at its upper end to the finger arm, and at its lower end to the
frame by a screw and thumb-nut.
The second rock-shaft is held from lateral movement by means of two sleeves
which surround the shaft and are arranged between the bearings and the finger
arm. The outer ends of the sleeves abut against the inner sides of the said
bearings and their opposite ends against the finger arm. By loosening the set
screw of the finger arm the second rock shaft can be adjusted in its bearings, and
the finger which is secured to the outer end of the shaft is thereby adjusted so as
to rest upon the corner of the pile of paper. By tightening. the finger arm upon
the second rock shaft the further lateral movement of the shaft is prevented by the
sleeves or collars.
An auxiliary vertical tension rod is guided at its upper end in the finger
arm, and near its lower end in a lug formed on the frame. A pin or split key is

page_text: inserted through an opening in the tension rod above the finger arm and a spiral
spring surrounds the said rod between the lug and a thumb nut engaging over the
lower threaded end of the rod. The tension of the spiral spring holds the tension
rod with its pin against the finger arm thereby increasing the pressure of the
finger upon the pile of paper.
A bent lever is pivotted to the inner side of one of the side frames and the
tension rod is provided with a reduced portion over which engages the bifurcated
end of the said bent lever so as to hold the tension rod.in an elevated position
and relieve the finger arm from the tension of the spiral spring. The said bent
lever is actuated by a cam on the counter shaft in such manner, that while the top
sheet of paper is being withdrawn from under the finger the latter is relieved from
the additional pressure of the spiral spring and tension rod; the finger at this
moment being held down upon the pile by the spring alone.. When the top sheet
has been removed from under the finger the tension rod is released by the bent
lever and cam and the pressure of the spiral spring forces the tension rod down-
ward, and bearing upon the finger arm increases the pressure of the finger upon
the pile, whereby the pile is more securely held in place upon the feed table.
The buckling finger is pivotted to the upper end of the upwardly extending arm
by a bolt passing through a slot in the said arm so that the buckling finger can be
adjusted backward or forward, as may be desired. The free end of the buckling
finger is bifurcated, and is provided with a roller of india rubber, or other suitable
material which is provided with journals. The journals of the rollers are seated in
elongated openings formed in the jaws of the bifurcated portion of the buckling
finger, in such manner that they move backwardly in the openings when the
roller moves forwardly over the paper during the buckling operation, and so that
the journals rest against the front ends of the openings when the roller moves
backwardly over the paper toward the finger. A blade is secured to the upper
side of the buckling finger and has its sharp front edge arranged at a short
distance in rear of the roller, so that the latter can turn freely when the journals
rest in the front portions of the openings but will impinge against the blade and
prevent the roller from rotating when the roller journals are moved backwardly in
the openings.
When the buckling finger is moved forwardly over the paper, the pressure of
the roller upon the paper causes the roller journals to move backwardly in the
openings, until the blade impinges against the roller. The roller is thereby
prevented from. turning and moves over the paper like a fixed bearing piece.
During the backward movement of the roller, the journals of the latter move
forwardly in the openings until they rest against the front ends of the openings
in which position the roller is free to turn, and consequently rolls over the paper
during the backward movement of the finger.
If desired, the roller may be provided with a ratchet wheel and the finger with a
pawl arranged so that the pawl will prevent. the rotation of the roller during the
forward movement of the finger and will permit its rotation during the backward
movement of the finger.
A pivotted finger is attached to the upwardly extending arm above the buckling
finger by a bolt passing through a slot in the said arm, so that the pivotted finger
may be adjusted backward or forward, as may be necessary. The free end of the
said finger is bifurcated and is provided with a roller preferably of metal, which is
provided with journals. The journals of the roller are seated in openings in the
bifurcated portions of the finger in the usual manner, so that the said roller may
turn freely when the finger is moved forward or backward. The pivotted finger is
made somewhat longer than the buckling finger, so that its roller will move over the
top sheet of the paper a suitable distance in front of the buckling roller to permit
the latter to buckle the top sheet against the roller. A roller or stud is attached
to the underside of the buckling finger and adapted to ride upon the upper side of
the first-mentioned finger during the last portion of the backward movement of
the buckling finger. An adjustable foot secured to the pivotted finger is adapted

page_text: to rest upon the top of the buckling finger when the latter, in its backward
movement, rides upon the first finger, so that both fingers are elevated a short
distance above the pile and away from the top sheet, and their pressure added
to the first finger, whereby the pile is more securely held in place on the feed
table. Spiral or other suitable springs are secured respectively at their upper ends
to the buckling and pivotted fingers, and at their lower ends to projections of the

springs serve to hold the fingers down upon the paper during their forward
movement, and also serve to increase the pressure on the first finger when the
buckling and pivotted fingers rest upon the same.
I prefer to construct each of the fingers in two parts connected together by
swivel joints whereby the rollers or other portions of the fingers which bear upon
the top sheet, are enabled to assume an inclined position and adjust themselves to
the inequalities of the upper surface of the pile. The swivelling movement of the
end portion of each finger is limited by overlapping portions of each tinger.
A gauge or foot rests upon the top sheet, and serves the double function of
regulating the upward feed motion of the feed table and of holding the pile of paper
in place. The said foot is arranged in such close proximity to the buckling finger
that it may be used in connection with the buckling finger as a buckling device.
The said foot is preferably made of a block of india-rubber or other elastic
material, and seated in a socket, which latter is provided with an upwardly
projecting screw stem which works in a threaded opening formed in a horizontal
arm and is secured in position, after being adjusted, by a jam-nut. The horizontal
arm is attached to an inwardly projecting arm by a vertical bolt passing through
a longitudinal slot in the horizontal arm, whereby the foot can be adjusted, as may
be required. The inwardly projecting arm is provided with a vertical socket
which is secured to a vertical bar by means of a set screw. The said socket is
arranged upon the vertical bar between two sleeves or collars in such manner as to
permit the inwardly projecting arm to swing on the rod, between the collars when
it is desired to change the position of the foot, to adapt it to different sized sheets
of paper. The vertical rod is guided at its upper and lower ends in lugs formed
on the adjacent side of the frame. A socket or stem secured to the vertical rod
above one of the lugs and is provided with an outwardly projecting stud or arm
guided in an elongated opening or slot formed in the frame. The said socket or
stem is adjustably secured to the vertical rod by means of a set screw.
A second elbow lever is pivotted to the side frame and has its long arm
bifurcated and engaging over the projecting end of a stud. The short arm of the
elbow lever is provided with a roller which is operated upon by a cam secured to
the counter shaft and formed in such manner that it will cause the foot to be lifted
from the top sheet when the latter is ready to be withdrawn from under the foot
by the feeding device. The foot is held down on the top sheet by a spring
surrounding the lower end of the vertical bar and which is interposed between
the lug of the frame and a pin or washer on the said vertical bar.
The feeding fingers whereby the top sheet is fed from the pile to the carrying
rollers are bifurcated at their lower ends, and provided with feeding rollers and a
stop device like that of the buckling finger, so that the said rollers operate like
a rigid bearing piece in moving forwardly, and carry the sheets of paper in their
forward movement, and roll over the underlying pile of paper in moving back-
wardly. The feeding fingers are pivotted at their upper ends to rock levers by
bolts passing through slots formed in the rock levers, so that the said fingers may
be set at any desired angle. The rock levers are adjustably secured at their upper
ends to a horizontal rock shaft by set screws which engage in a longitudinal slot
formed on one side of the rock shaft, whereby both rock levers are held in parallel
lines thereby facilitating the adjustment of the feeding fingers when it becomes

supported in bearings formed on the frames. An arm is arranged at an angle
to the rock levers and secured to the rock shaft by a screw nut; a vertical rod

page_text: connects the last mentioned arm with the end of the long arm of the third elbow
lever.
The said third lever is pivotted to the inner side of one of the side frames and
the short arm of the said lever is provided with a roller which engages in a cam
groove formed in the disc secured to the counter shaft by means of which an
intermittent reciprocating movement is imparted to the feeding fingers. The rock
lovers are provided with flat springs arranged on the sides adjacent to the fingers
so as to bear against the same when they are placed in an elevated position above
the pile and hold the fingers up away from the work when required.
A pawl engages with the ratched rim of the hand wheel hereinbefore mentioned.
The said pawl is pivotted to the upper end of a fourth elbow lever which is
pivotted to the outer side of the frame. The lower arm of the fourth elbow lever is
provided with a roller which is operated upon by a cam secured to the counter
shaft. The said cam is so formed that it will impart a rocking motion to the said.
lever thereby moving the pawl back and forth over the ratchet rim. A projection
or nose is formed on the lower arm of the fourth elbow lever and engages against
a shoulder on the outer side of the second elbow lever whereby the stroke of the
fourth elbow lever and the motion which the pawl produces in the ratchet wheel
are regulated. In the same measure as the foot descends by the removal of the
sheets from the top of the pile, the second elbow lever and the stop descend also,
whereby the oscillation of the fourth elbow lever and the stroke of the pawl are
increased, so that the rotation of the hand. wheel and the feed screws is pro-
portionate to and controlled by, the amount of paper which is removed from the
top of the pile. The pawl is held in engagement with the ratchet rim by a spring
which is seated upon a lug on the fourth elbow lever and surrounds a sliding rod
attached at its upper end to the pawl. The said spring bears with its upper end
against a pin or collar on the sliding rod thereby pressing the pawl upward against
the ratchet rim and keeping the same in engagement therewith.
In order to lower the feed table, the pawl is disconnected from the ratchet rim
when the feed table can be lowered by hand for supplying a fresh charge of paper
to the machine.
A grooved tape roller is arranged in front of the feed table with its upper
surface in line with the top sheet, so as to receive on its upper surface the top
sheet as the latter is removed from the pile by the feed fingers. Rollers are
mounted upon a horizontal shaft and are faced with india-rubber, or other suitable
material, so as to bite against the paper when brought in contact therewith. The
horizontal shaft is journalled in arms suspended from a transverse rock shaft which
is journalled in the side frames, and is supported by the said arms so that the
rollers will rest by their weight upon the tape roller.
A cone pulley mounted on the driving shaft and a similar cone pulley is formed
with or secured to the tape roller. Motion is imparted to the second pulley from
the first cone pulley by means of an endless belt or in any other suitable manner.
A shipper bar or lever whereby a clutch is thrown in and out of gear, and the
motion of the machine arrested when desired, is provided. This bar is supported
at one end in a bearing formed on the frame and is provided with a finger or bar
which engages in the annular groove of the clutch. The opposite end of the
shipper bar is pivotted to a vertical hand lever which is pivotted at its lower end
to the frame by a pivot bolt. By moving the hand lever backward, the shipper
bar is shifted and the motion of the machine arrested.
A horizontal rock lever is pivotted to the frame and connected at its outer end
to the upper end of the said hand lever and provided at its inner end with a
downwardly projecting finger.
A horizontal shifting plate is arranged on the under side of the feed table and
supported and guided by a horizontal channel plate secured to the under side of
the feed table. The shifting plate is provided at its outer end with an elongated
slot or opening and is so arranged that when the table is raised to nearly the limit

page_text: of its upward movement, the said opening will engage over the finger or pin of the
horizontal rock lever. A downwardly projecting arm or lug is formed on or
secured to the channel plate and a vertical bifurcated pawl or lever is pivotted at
its lower end to the downwardly projecting arm and has its upper end extending.
through a slot formed in the table A bell crank lever is pivotted to the under side
of the table. One arm of the said lever is pivotted to the shifting plate and the
opposite arm of the lever engages in the bifurcated portion of a pawl or dog.
A spiral spring is secured at one end to the bell crank lever and at its opposite end
to the downwardly projecting arm whereby the shifting plate is held with its outer
slotted end in a forward position, in which position the slot of the plate will engage
over the finger of the rock lever when the table has reached the proper height.
The slot which is formed in the table is arranged in line with one of the feeding
fingers, so that the feed roller in feeding the paper from the pile will roll in a line
directly over the slot. The upper end of the pawl or dog projects through the slot,
so that its upper end will be nearly in line with the top of the table, but will not.
extend above the same.
A pawl or finger is pivotted to one of the feeding fingers, so as to rest with its
free end upon the pile of paper. When the last sheet of paper has been fed from
the table by the feeding fingers, the pawl or finger drops into a slot so that its free
end engages against the upper end of the pawl or dog, and moves the same
forwardly in the slot. During this movement of the pawl, the shifting plate is
moved inwardly by the bell crank lever engaging with the pawl, and the finger of.
the rock lever being now engaged in the slot of the shifting plate causes the rock
lever to swing on its pivot and shift the hand lever, whereby the further
movement of the machine is automatically stopped.
By disengaging the pawl or finger from the pawl or dog the shifting plate and.
the pawl or dog are again brought back to their former position by the action of
a spring. The slot of the shifting plate is made sufficiently long to permit of this
movement. without disturbing the shipper bar. The table can now be lowered for
a fresh supply of paper by turning the hand wheel. To again start the machine it
is only necessary to give the hand lever a sufficient forward movement to cause
the clutch to engage with the driving wheel, when the finger of the rock lever and
the slot are again in a vertical line ready to engage when the table has reached the
proper height. A hand wheel provided in its hub with an internal screw thread
engages with an external screw thread formed on one of the stay rods which.
connect the side frames of the machine, which is supported on two parallel. plates
secured to the floor. The feet of the side frames rest upon tracks formed on the
said parallel plates and are guided by upwardly projecting flanges formed along
the inner edges of the plates. Upwardly projecting studs or lugs are formed on
one of the parallel plates and are arranged on opposite sides of the hub of the hand
wheel, whereby the said wheel is confined between the studs and prevented from
moving longitudinally over the screw thread. By turning the hand wheel in one
or the other direction the threaded hub engaging with the screw thread causes the
machine to be moved longitudinally on the parallel plates whereby the position of
the machine can be adjusted with reference to a ruling or other machine which
receives the paper from the feeding machine.
The operation of the machine is as follows that is to say.
The pile of paper being placed upon the feed table the first finger buckling and
pivotted fingers, foot, and feeding fingers all rest upon the top sheet. The forward
movement of the buckling finger draws the corner of the top sheet from under the
first finger and buckles the corner of the said sheet against the roller of the pivotted
finger thereby separating the top sheet from the pile. The buckling and pivotted
fingers on their return movement are raised from the separated sheet by the first
finger and ride upon the latter. The tension rod is released at the same time by
the action of the cam on the bent lever and these parts add their combined
pressure to that of the first finger, thereby holding the latter tightly upon the pile
of paper.

page_text: The foot is now lifted from the top sheet by its actuating mechanism and the
feeding fingers begin their forward movement and cause the top sheet to move
toward the tape and india rubber rollers until the latter grip the front edge of the
top sheet. The sheet is then fed forward by the said rollers upon the carrying
tapes. After the feeding fingers have completed their forward movement they are
brought back by the action of the grooved cam and connecting parts, and when
they have reached the limit of their backward movement they remain at rest upon
the top sheet, until the buckling device has again moved forward and buckled the
top sheet. When the buckling fingers have returned and rest upon the top of the
first finger, the feeding fingers again begin their forward movement and carry
the top sheet between the last mentioned rollers and so the movements of the
parts continue until the last sheet has been fed from the table when the pawl or
finger drops into the slot in the table and engages against a lever and thereby shifts
the clutch mechanism and stops the movement of the machine.
·
For adapting the improved machine for use in connection with a printing press,
the stationary frame of the machine may be attached to the frame of the printing
press in such manner that the machine takes the place of the ordinary feed board.
The horizontal driving shaft of the machine is arranged transversely at the rear
end of the frame and journalled in bearings secured thereto. A sprocket or chain
wheel is mounted loosely on one end of the driving shaft, and is connected with
a similar wheel on the shaft of the press cylinder, or other shaft from which
power is derived by the drive chain. The sprocket or chain wheel is connected
with the driving shaft by a sliding bolt which is attached to the said sprocket
wheel and engages with a ratchet wheel secured to the driving shaft. This ratchet
wheel is provided with a single tooth so that when the feeder is connected witli
the printing press, the feeder will always start at a given point with reference to°
the press.
same,
The table upon which the pile of paper is placed is supported by downwardly
extending rack bars which engage with pinions. The latter are mounted on
horizontal shafts arranged underneath the table parallel with the driving shaft
and journalled in bearings secured to the main frame. The rack bars are held in
contact with the pinions by guide caps which are hung on the horizontal shafts
and bear against the rear sides of the rack bars. A counter-shaft is arranged on
one side of the main frame at right angles to the horizontal shafts and below the
and has secured to it worms engaging with worin wheels secured to the ends
of the horizontal shafts whereby motion is transmitted from the counter shaft to
the horizontal shafts. The counter shaft is journalled in bearings secured to the
main frame. A ratchet wheel is secured to the rear end of the counter shaft and
an actuating pawl engages with the said ratchet wheel. This pawl is attached to
the end of an arm which is mounted loosely on the counter shaft near the driving
shaft and which is actuated by a cam mounted on the end of the driving shaft.
The said arm is provided with a nose or projection which engages against the face
of the said cam, so that the arm is moved by the cam in the direction in which
the pawl slides over the ratchets of the ratchet wheel and gives no motion to
the same.
A spiral spring is secured with one end to the hub of the said arm and attached
with its other end to an adjusting rod on which it is adjustably held by a thumb
nut by which the pressure of the spring can be regulated. The adjusting rod is
secured to one of the bearings or to some other part of the machine The spiral
spring presses the arm against the cam and causes the said arm to swing toward
the cam as the arm is released by the cam, so that a rocking movement is imparted
to the arm in one direction by the cam and in the other direction by the spring.
The movement of the arm produced by the spring takes place in the direction in
which the pawl'engages with the ratchets of the ratchet wheel and turns the latter,
so that the motion of the ratchet wheel and of the counter shaft and horizontal
shafts is produced by the pressure of the spring while the cam merely serves to
swing the arm backward and place the pawl in position to begin its operative

page_text: movement. The motion which is produced in the horizontal shafts by the spring
causes an upward movement of the rack bars and table.
A holding-down finger is arranged near one corner of the pile of paper and
attached to a spring bar which is secured with its forward end to a cross piece of
the main frame. A guage finger is arranged to bear upon the paper in front of
the holding down finger and is attached to a second spring bar which is secured
with its front end to a cross piece. The rear ends of the spring bars are connected
respectively by rods with cams secured to the driving shaft. The lower ends of
the said rods are constructed in the form of open frames or heads which enclose
the cams The spring arms hold the frames against the under sides of the cams so
that the downward movement of the spring bars is produced by the cams, while
their upward movement is produced by their elasticity which causes the frames to
follow the cams during their upward movement. The frames are guided in a
block which is arranged between the frames and provided with upright ways in
which the frames move. One cam is formed on a sleeve which is secured to the
driving shaft by a set screw and the other cam is secured to the said sleeve by a
set screw so that these cams and parts connected therewith can be adjusted on thé
driving shaft by simply releasing the set screw. The cams are so formed as to
alternately raise and lower the holding-down finger and the gauge finger, both
fingers being down on the paper an instant before either rises. The front ends of
the arms are laterally adjustable on the cross piece in order to adapt the fingers
and their actuating parts to the width of the pile of paper."
The holding down finger performs the double function of holding the pile with
a strong pressure when the gauge finger is raised and also holding the top sheet
• with a light pressure in separating the top sheet from the pile. In order to
accomplish this the holding down finger is attached to the lower end of a rod
which slides vertically in the lugs of a carrier which latter is secured to one of
the spring bars. The said rod is pressed downwardly by a light spring which is
attached with one end to the carrier and with its other end to the rod. A vertical
set screw is attached to the carrier and terminates a short distance above the
holding down finger. When its spring bar is lowered by the cam the lower end
of the set screw strikes upon the holding down finger and presses the latter
downwardly against the paper, thus securely holding the pile with a strong
pressure. When the said spring bar is raised, so that the set screw is raised from
the holding down finger the latter is lightly held down upon the paper by the
spring. By adjusting the set screw the precise point at which the strong pressure
is applied to the holding down finger is nicely regulated.
The carrier is provided with a vertical slot through which a spring bar passes.
The holding down finger is attached to the rod by a pivotal joint, the pivots
standing at right angles to the length of the bar, the lower end of the rod being
bifurcated to straddle the upper end of the said finger. The upper pivoted end of
the finger is provided at its front side with a shoulder which bears against the rod
when the finger is in an upright position and which prevents the said finger from
swinging forwardly beyond its upright position, while the finger is free to swing
backwardly:
A light spring is secured to the lower end of the rod and bears with its lower
end against the holding down finger tending to hold the latter in an upright
position, but permitting the finger to yield rearwardly under pressure. By this
means the finger is allowed to yield backwardly as the spring bar is lowered, and
prevented from assuming a forwardly inclined position with reference to the surface
of the pile of paper, which it would do if the holding down finger were rigidly
attached to the bar owing to the curvilinear movement of the finger, by reason of
the spring bar being substantially a pivoted bar. This slight curvilinear movement
would cause a rigid finger to work the pile gradually forward out of place but this
is prevented by rendering the finger backwardly yielding..as above described,
because the joint in the finger. permits..the latter to maintain a vertical position

page_text: on the pile irrespective of the movements of the bar. The carrier is adjustably
secured to the spring bar by set screws.
The gauge finger is attached to a carrier by means of a vertical screw shank
which works in a threaded opening in the carrier and is clamped on the same by a
thumb nut. The said shank is provided at its lower end with a ball which engages
in a spherical socket in the gauge finger, thereby rendering the said finger yielding
in all directions and permitting the finger to adjust itself to the uneven or wavy
surface of the pile. The gauge finger is held in an upright position by an elastic
sleeve of india rubber or coiled wire which surrounds the finger and the lower
portion of the shank and permits the finger to yield, but holds the finger substan-
tially in an upright position in the absence of any disturbing force. The lower
end of the gauge finger is faced with india rubber which affords a firm bearing on
the paper.
The carrier is adjustably secured to a spring bar by a set screw.
The gauge
finger resists the upward movement of the pile and this resistance is transmitted
to a spring which latter tends to feed up the pile against the gauge finger so that
by increasing or reducing the pressure of the spring the feed is increased or
reduced.
The buckling finger, whereby the top sheet is buckled against the gauge finger
and separated from the pile, is provided at its front end with a roller which
bears upon the paper, and a stop device whereby the roller is prevented from
rotating during the forward movement of the finger and permitted to rotate during
the backward movement of the finger as herein before described. A rock arm
whereby the buckling finger is actuated is mounted loosely upon a horizontal shaft
or rod which is arranged parallel with the driving shaft below the main frame.
The upper end of the rock arm is provided with an extension to which the buckling
finger is adjustably attached by a bolt passing through a slot in an extension
whereby the throw of the buckling finger can be increased or reduced. The rock
arm is swung forwardly by a cam secured to the driving shaft and backwardly by
a spring. The throw of the rock arm is regulated by an adjustable stop which is
secured to the rock arm and comes in contact with the main frame, thereby
determining the initial position of the rock arm. The body of the buckling finger
is composed of a coiled spring which tends to hold the roller of the buckling finger
down upon the paper and at the same time permits the roller to assume an inclined
position laterally in adjusting itself to the uneven surface of the paper. The said'
extension is attached to the rock arm by a bolt on which the extension can be
adjusted so as to regulate the position of the buckling finger on the paper and the
operative length of the rock arm by which the buckling finger is moved.
The feeding fingers are provided at their front ends, with rollers like the rollers
previously described, and attached with their rear ends to the rock arm which is
mounted loosely on the horizontal shaft and swung forwardly by cams secured to
the driving shaft and backwardly by springs.
When the buckling finger moves forward to separate the top sheet the holding
down finger is raised and bears upon the corners of the pile with a slight pressure.
When the top sheet has been separated the holding down finger is lowered and
presses upon the corner of the pile with a heavy pressure, thereby holding the pile
in place. The gauge finger is next raised to release the top sheet and the feeding
fingers then move forwardly and remove the top sheet.
A duplex spring is arranged between the feed table and the stationary frame,
and rests with its lower arms upon the frame and with its upper arms against the
table. This spring exerts an upward pressure against the table which is adjusted
sufficiently to compensate for the weight of the pile and which grows less as the
spring becomes expanded in raising the table, in the saine measure as the weight
of the pile is reduced by feeding off the paper.
The spring substantially relieves the parts which feed the table from the weight
of the pile of paper, and thereby renders the feeding mechanism more sensitive to
the changes which take place in feeding off the paper.

page_text: The lower feed roller is arranged between the front portion of the main frame
and has its shaft journalled in bearings formed in said frame. The upper feed
rollers rest upon the lower feed-roller which is provided with annular grooves in
which run the feed or carrying tapes running around the tail rollers. The latter
roller is journalled in a frame which is hung loosely upon the shaft of the lower
feed roller so that the frame can be turned on the shaft as an axis. The upper
feed rollers are journalled in side bars which are pivoted at their lower ends to
the roller frame. Cross bars connect the side bars of the roller frame near their
front and rear ends.
Travelling endless guide belts are arranged on the inner sides of the side bars of
the roller frame, to guide the paper as it passes over the tapes. Each endless belt
runs around two pulleys or wheels which turn on studs secured to longitudinal
bars. The latter are adjustably secured with their front ends to one cross bar and
with their rear ends to the other cross bar. Each pulley is rotated by an endless
cord which runs around a grooved pulley formed at the lower end of the pulley or
roller and around the lower feed rollers, from which the endless cord derives its
motion in such manner that the inner portion of each endless belt runs in the
direction in which the paper moves over the tapes. The endless cord is half
twisted and guided by a grooved roller attached to a longitudinal bar. The tapes
may be arranged slightly obliquely toward the endless bolt against which it is
desired to feed the paper. The lower feed roller is driven from the driving shaft
by an endless belt running around pulleys secured respectively to the driving shaft
and the shaft of the feed roller.
It will be seen that all parts of the feeder are driven from the driving shaft.
The tail roller delivers the paper to the printing press or other machine with which
the feeder is connected. By engaging a hook with the tail roller or some other
part of the roller frame, the said frame and the parts supported on the same can be
raised up when it is desired to have access to the cylinder of the printing press
for making ready, or to such other machine with which the feeder is connected.
The feeding fingers move forwardly until the front portion of the top sheet is
firmly siezed by the feed rollers. The latter then move the sheet forwardly upon
the tapes and the tapes convey the sheet onward and register the sheet against one
or the other of the travelling side guides. The travelling side guides can be
adjusted toward or from the sides of the roller frame by adjusting the bars on
the rods.
The buckling finger and the feed fingers have a rectilinear reciprocating move-
ment in the same direction on the pile, whereby the lateral displacement of the top
sheet is avoided and the actuating mechanism of the fingers is greatly simplified..

Paper to Printing, Folding, and other Machines.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of my invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR FEEDING
SHEETS OF PAPER TO PRINTING, FOLDING AND OTHER MACHINES" 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 machines or apparatus for feeding sheets of paper, one
after another, to ruling, folding or calendering machines, printing presses and other
machines which are supplied with sheets of paper, and more particularly to a
machine of this kind in which the pile of paper is supported on a table which is
automatically raised as the sheets of paper are successively fed from the top of the
pile. by the buckling and feeding devices and placed within reach of the feed rollers
or tapes which move the sheets onward one after the other. The object of this
invention is to simplify the construction of the machine and to render it more
efficient and reliable in its operation.

In Figures 1 to 16, which represent the construction of the machine suitable for
use in connection with ruling and similar machines, A A represent the side frames
of the machine connected by cross stays a a. A represents the feed table upon
which the pile of paper A³ is placed. The feed table A¹ is secured to supports a¹
which are provided near their outer ends with screw nuts a² and upright
extensions a³, having rollers a, which run in vertical grooves a, formed on the
inner sides of the side frames A, whereby the feed table is guided in its vertical
movements. b represents vertical screws which work in the screw nuts a² secured
to the feed table, and which are held against lengthwise movement in bearings bl
secured to the side frames A. B represents a hand wheel secured to the upper end
of one of the feed screws, and provided on its underside with an annular ratchet
rim b. The lower ends of the feed screws bb are connected by a horizontal
shaft b³, and bevel wheels b, so that both feed screws are actuated simultaneously.
b³ represents stationary vertical guides arranged upon cross bars 66 secured to the
side frames A. The guides 65 are arranged closely against the front of the
table A¹, so as to support the front of the pile of paper on the table, and prevent
the same from tipping or tilting forwardly. Similar guides may also be arranged
adjacent to the table and the outer side of the pile of paper on the same.
b7 represents outwardly projecting arms or brackets secured at their inner ends
to the side frames A, and provided with longitudinal slots 68. 69 is an adjustable
vertical guide secured at its ends to the brackets 67 by means of thumb screws 610,
passing through the alots 68 of the brackets. By this means the guide b° can be
adjusted backwardly and forwardly for different sized piles of sheets placed upon
the table. The upper bracket 67 also serves to support the buckling mechanism
when the table Ai is lowered to receive a fresh supply of paper.
C represents the horizontal driving shaft arranged transversely in the machine
and supported in bearings in the side frames A. C¹ represents a counter-shaft
arranged below the driving shaft C and parallel with the same. Motion is trans-
mitted from the driving shaft C by a train of gear wheels c c¹ c², in such manner
that the speed of the counter shaft C¹ can be increased or reduced by changing the
size of the gear wheels c³ and adjusting the size of the gear wheel c' accordingly.
c³ represents a clutch coupling whereby the driving pulley C can be thrown in and
out of gear, as desired. D represents a horizontal rock shaft arranged at right
angles to the shafts C C¹, and supported in bearings d d formed on one of the side
frames A, and D represents a similar rock shaft arranged parallel with the shaft D
and above the same, and supported in bearings d' d formed on the side frame A.
D' is a strap or link connecting the shafts D D¹ near their outer ends, so as to
prevent the same from springing or bending when they are extended as shown in
Figure 1.
The strap D2 is held from lateral displacement by the finger F and a collar D³
which are secured to the shaft D¹ on opposite sides of the strap D².
E represents an upwardly extending arm secured to the shaft D, and to the upper
end of which the buckling device is attached.

page_text: El represents an elbow lever which is pivotted to the inner side of one of the
side frames A, by nieans of a pivot bolt e. E represents a lever secured to the
rock shaft D by means of a set screw e¹. The lever E2 extends inwardly. through
an elongated opening or slot c³, formed in one of the side frames A, whereby the
lever and the shaft D are held from lateral displacement. The set screw e¹ of the
lever E engages in a longitudinal slot or groove formed in the shaft D, so that by
loosening the screw e¹, the shaft D may be moved laterally in its bearings to adjust
the arm E, and buckling device attached thereto, to the different sizes of sheets of
paper. e³ is a vertical rod connecting the inner end of the lever E* with the hori-
zontal arm e of the elbow lever E¹. 6 is the vertical arm of the elbow lover E'
which is bifurcated to engage over a cam e, secured to the counter shaft C¹, whereby
motion is imparted to the lever E¹, rod e³, lever E' and rock shaft D.
F represents a finger which is secured to the end of the shaft D¹ by a set screw f,
and which rests with its free end upon the corner of the pile of paper adjacent to
the buckling device. The finger F is held down upon the pile of paper by means
of an arın F¹, which is secured to the shaft D₁ by a set screw f', and a spiral
spring which is secured at its upper end to the armi F¹, and at its lower end to
the frame A by a screw f³ and thumb nut f. The shaft D¹ is held from lateral
movement by means of two sleeves d³, which surround the shaft and are arranged
between the bearings and the arm F¹. The outer ends of the sleeves abut
against the inner sides of the bearings d¹, and their opposite ends against the arm F.
By loosening the set screw fl of the arm F¹, the shaft D¹ can be adjusted in its
bearings and the finger F which is secured to the outer end of the shaft is thereby
adjusted so as to rest upon the corner of the pile of paper. By tightening the
arm F¹ upon the shaft D¹ the further lateral movement of the shaft is prevented by
the sleeves or collars d³.
G represents an auxiliary vertical tension rod which is guided at its upper end in
the arm F¹, and near its lower end in a lug g formed on the frame A. g² is a pin
or split key inserted through an opening in the rod G above the arm F¹, and g³ is
a spiral spring which surrounds the rod G between the lug g, and a thumb nut g'
engaging over the lower threaded end of the rod G. The tension of the spring g³
holds the rod G with its pin g against the arm F¹, thereby increasing the pressure
of the finger F upon the pile of paper. G¹ represents an elbow lever which is
pivotted at go to the inner side of one of the side frames A. The rod G is provided
with a reduced portion go, over which engages the bifurcated end g¹ of the elbow
lever G¹, so as to hold the rod G in an elevated position and relieve the arm F¹
from the tension of the spring 93. The elbow lever G¹ is actuated by a cam g' on
the counter shaft C' in such manner, that while the top sheet of paper is being
withdrawn from under the finger F the latter is relieved from the additional
pressure of the spring g³ and rod G; the finger F at this movement being held
down upon the pile by the spring f" alone. When the top sheet has been removed
from under the finger F, the rod G is released by the elbow lever G¹ and cam g',
and the pressure of the spring g³ forces the rod G downward, and bearing upon the
arm F¹ increases the pressure of the finger F upon the pile, whereby the pile is
more securely held in place upon the feed table.
Hrepresents the buckling finger which is pivotted to the upper end of the rock
arm E by a bolt h, passing through a slot ' in the rock arm, so that the finger can
be adjusted backward or forward, as may be desired. The free end of the finger H
is bifurcated, and is provided with a roller of rubber, or other suitable material,
which is provided with journals h³. The journals of the rollers are seated in
elongated openings, formed in the jaws of the bifurcated portion of the finger H
in such manner, that the journals nove backwardly in the openings h*, when the
roller moves forwardly over the paper during the buckling operation, and so that
the journals rest against the front ends of the openings h, when the roller moves
backwardly over the paper toward the finger F. h is a blade secured to the upper
side of the finger H and having its edge arranged at a short distance in rear of the
roller, so that the latter can turn freely when the journals rest in the front

page_text: portions of the openings h, but will impinge against the blade and prevent
the roller from rotating when the roller journals are moved backwardly in the
openings h'.
When the finger H is moved forwardly over the paper, the pressure of the roller
upon the paper causes the roller journals to move backwardly in the openings h4,
until the blade * impinges against the roller. The roller is thereby prevented from
turning and moves over the paper like a fixed bearing piece. During the backward
'movement of the roller, the journals of the latter move forwardly in the openings h*
until they rest against the front ends of the openings h, in which position the
roller is free to turn, and consequently rolls over the paper during the backward
movement of the finger.
If desired the roller may be provided with a ratchet wheel and the finger with
n pawl arranged so that the pawl will prevent the rotation of the roller during
the forward movement of the finger and will permit its rotation during the
backward movement of the finger, as represented in Figure 16.
I represents a finger which is pivotted to the rock arm E, above the finger H, by
a bolt passing through a slot in the rock arm, so that the finger may be
adjusted backward or forward, as may be necessary. The free end of the finger I
is bifurcated and is provided with a roller ², preferably of metal, which is provided
with journals. The journals of the roller 2 are seated in openings in the
bifurcated portions of the finger I in the usual manner, so that the roller i¹ may
turn freely when the finger I is moved forward or backward. The finger I is made
somewhat longer than the finger H, so that its roller will move over the top sheet
of the paper a suitable distance in front of the buckling roller h², to permit the
latter to buckle the top sheet against the roller ². is a roller or stud attached
to the under side of the finger H, and adapted to ride upon the upper side of the
finger F during the last portion of the backward movement of the finger H. 2 is
an adjustable foot secured to the finger I, and which is adapted to rest upon the top
of the finger H when the latter, in its backward movement, rides upon the finger F;
so that both fingers are elevated a short distance above the pile and away from the
top sheet, and their pressure added to the finger F, whereby the pile is more securely
held in place on the feed table. 27 18 are spiral or other suitable springs secured
respectively at their upper ends to the fingers H and I, and at their lower ends to
projections of the lever E, by means of screw stems 210 and thumb nuts 2. The
springs serve to hold the fingers down upon the paper during their forward
movement, and also serve to increase the pressure on the finger F when the fingers H
and I rest upon the same.
I prefer to construct each of the fingers F, H and I in two parts connected
together by swivel joints he, h, whereby the rollers or other portions of the fingers
which bear upon the top sheet, are enabled to assume an inclined position and
adjust themselves to the inequalities of the upper surface of the pile. The
swivelling movement of the end portion of each finger is limited by the over-
lapping portions h³ of each finger.
J represents a gauge or foot which rests upon the top sheet, and which serves
the double function of regulating the upward feed motion of the table A¹ and of
holding the pile of paper in place. The foot J is arranged in such close proximity
to the buckling finger H, that it may be used in connection with the buckling
finger Has a buckling device. The foot J is preferably made of a block of india
rubber or other elastic material, and seated in a socket j, which latter is provided
with an upwardly projecting screw stem j¹, which works in a threaded opening
formed in a horizontal arm, and is secured in position after being adjusted, by a
jam-nut j. The arm j³ is attached to an inwardly projecting arm by a vertical
bolt j, passing through a longitudinal slot 6 in the arm ja, whereby the foot J can
be adjusted, as may be required. The arm 7 is provided with a vertical socket j
which is secured to a vertical bar K, by means of a set screw j8. The socket 37, of
the arin j is arranged upon the bar K between two sleeves or collars k, k in such

page_text: The
manner, as to permit the arm 7 to swing on the rod K, between the collars k k
when it is desired to change the position of the foot, to adapt it to different sized
sheets of paper. The rod K is guided at its upper and lower ends in lugs k¹ k²,
formed on the adjacent side of the frame A. ³ is a socket or stem secured to the
rod K above the lug 2, and which is provided with an outwardly projecting stud
or arm guided in an elongated opening or slot formed in the frame A.
socket is adjustably secured to the vertical rod K by means of a set screw kº.
L is an elbow lever pivotted to the side frame A, at 1, and having its arm
bifurcated at 1, and engaging over the projecting end of the stud k*.
arm of the elbow lever L is provided with a roller ³, which is operated upon by a
cam secured to the counter shaft C¹, and formed in such manner that it will
cause the foot J to be lifted from the top sheet when the latter is ready to be
withdrawn from under the foot J by the feeding device. The foot J is held down
on the top sheet by a spring surrounding the lower end of the bar K and which
is interposed between the lug k³ of the frame A, and a pin or washer 1 on the
bar K.
The short
M M represent the feeding fingers whereby the top sheet is fed from the pile to
the carrying rollers. The fingers M M are bifurcated at their lower ends and
provided with rollers m, m, and a stop device like that of the buckling finger H, so
that the rollers m m, operate like a rigid bearing piece in moving forwardly, and
carry the sheets of paper in their forward movement, and roll over the underlying
pile of paper in moving backwardly. The fingers M M are pivotted at their upper
ends to rock levers M M¹ by bolts m¹ m¹, passing through slots m³, formed in the
rock levers M¹ M₁, so that the fingers M M may be set at any desired angle. The
rock levers M¹ M¹ are adjustably secured at their upper ends to a horizontal rock
shaft M' by set screws m³. The set screws m³, engage in a longitudinal slot formed
on one side of the rock shaft M³, whereby both rock levers are held in parallel
lines, thereby facilitating the adjustment of the fingers M M when it becomes
necessary to adjust the fingers to different sizes of sheets. The rock shaft M² is
supported in bearings m³, formed on the frames A. A. m is an arm arranged at
an angle to the rock levers M¹ M¹, and secured to the rock shaft M' by a screw
nut m. m³ is a vertical rod connecting the arm me with the end of the long arm
of an elbow lever N. The lever N is pivotted at n to the inner side of one of the
side frames A, and the short arm m¹, of the lever N is provided with a roller n³
which engages in a cam groove na formed in the disc N secured to the counter
shaft C by means of which an intermittent reciprocating movement is imparted to
the fingers M M. The rock levers M¹ are provided with flat springs m³ arranged
on the sides adjacent to the fingers M, so as to bear against the same when they
are placed in an elevated position above the pile and hold the fingers up away from
the work when required.
o represents a pawl which engages with the ratchet rim 6 of the hand wheel B.
The pawl o is pivotted to the upper end of an elbow lever O, which is pivotted to
the outer side of the side frame A, at o¹. The lower arm of the lever O is provided
with a roller o³, which is operated upon by a cam o³, secured to the counter shaft C¹.
The cam 0 is so formed, that it will impart a rocking motion to the lever O,
thereby moving the pawl o back and forth over the ratchet rim b². o* is a pro-
jection or nose formed on the lower arm of the lever O, and which engages against
a shoulder os on the outer side of the lever L, whereby the stroke of the lever O,
and the motion which the pawl o produces in the ratchet wheel 6 are regulated.
In the same manner as the foot J descends by the removal of the sheets from the
top of the pile, the lever L and the stop o descend also, whereby the oscillation of
the lever O, and the stroke of the pawl o are increased, so that the rotation of the
wheel B and the feed screws bb, is proportionate to, and controlled by the amount
of paper which is removed from the top of the pile. The pawl o is held in engage-
ment with the ratchet rim 6² by a spring o, which is seated upon a lug o' on the
lever O, and surrounds a sliding rod 08, attached at its upper end to the pawl o.,
The spring of bears with its upper end against a pin or collar on the rod o8 thereby.

page_text: pressing the pawl upward against the ratchet rim b³ and keeping the same in
engagement therewith.
In order to lower the feed table, the pawl o is disconnected from the ratchet
rim b², when the feed table can be lowered by hand for supplying a fresh charge of
paper to the machine.
P represents the grooved tape roller arranged in front of the feed table A¹ with
its upper surface in line with the top sheet, so as to receive on its upper surface
the top sheet as the latter is removed from the pile by the fingers M. P¹ are
rollers mounted upon a horizontal shaft p, and faced with india-rubber, or other
suitable material, so as to bite against the paper when brought in contact therewith.
The shaft p is journalled in arms pl pl suspended from a transverse rock shaft p³
which is journalled in the side frames A. The shaft p is supported by the arms p¹,
so that the rollers P¹ will rest by their weight upon the tape roller P.
S represents a cone pulley formed with or secured to the roller P. Motion is
imparted to the pulley S¹ from the cone pulley S by means of an endless belts,
or in any other suitable manner. T represents the shipper-bar or lever whereby
the clutch is thrown in and out of gear, and the motion of the machine arrested
when desired. The bar T is supported at one end in a bearing t formed on the
frame A, and is provided with a finger or bar t¹ which engages in the annular
groove of the clutch 3. The opposite end of the bar T is pivotted at t³ to a
vertical hand lever which is pivotted at its lower end to the frame A by
a pivot bolt ť³.
By moving the hand lever t backward the shipper bar T is shifted and the
motion of the machine arrested. to represents a horizontal rock lever pivotted
'at t' to the frame A and connected at its outer end to the upper end of the hand
lever and provided at its inner end with a downwardly projecting finger t³.
R represents a horizontal shifting plate which is arranged on the under side of
the feed table A¹ and supported and guided by a horizontal channel plate >
secured to the under side of the feed table. The plate R is provided at its outer
end with an elongated slot or opening r¹, and is so arranged that when the table
is raised to nearly the limit of its upward movement the opening will engage
over the finger or pin ts of the rock lever to. is a downwardly projecting arm
or lug formed on or secured to the plate r; and 3 represents a vertical bifurcated
pawl or lever pivotted at its lower end to the arm 72 and having its upper end
extending through a slot formed in the table A¹. represents a bell crank or
elbow lever pivotted at r to the under side of the table A¹. One arm of the
lever is pivotted to the shifting plate R and the opposite arm of the lever r³
engages in the bifurcated portion of the pawl or dog ³ 77 represents a spiral
spring secured at one end to the elbow lever and at its opposite end to the
arm whereby the shifting lever R is held with its outer slotted end in
a forward position, in which position the slot 1 of the lever R will engage over
the finger 8 of the lever to when the table has reached the proper height. The
slot which is formed in the table A¹ is arranged in line with one of the feeding
fingers M, so that the feed roller in feeding the paper from the pile will roll in
a line directly over the slot. The upper end of the pawl or lever projects
through the slot 4, so that its upper end will be nearly in line with the top of the
table, but will not extend above the same.
u represents a pawl or finger pivotted to one of the feeding fingers M, so as to
rest with its free end upon the pile of paper. When the last sheet of paper has
been fed from the table A¹ by the feeding fingers M, the pawl or finger u drops
into the slot, so that its free end engages against the upper end of the pawl or
lever, and moves the same forwardly in the slot. During this movement of
the pawl, the shifting plate R is moved inwardly by the bell crank lever 3
engaging with the pawl, and the finger ts of the rock lever to being Dow
engaged in the slot of the shifting lever R, causes the rock lever to to swing
on its pivot and shift the band lever t, whereby the further movement of the
machine is automatically stopped.

page_text: By disengaging the finger u from the pawl the shifting lever and the pawl
are again brought back to their former position by the action of the spring 77,
The slot of the lever R is made sufficiently long to permit of this movement
without disturbing the shipper bar T. The table can now be lowered for a fresh
supply of paper by turning the hand wheel B. To again start the machine it is
only necessary to give the hand lever t¹ a sufficient forward movement to cause
the clutch c³ to engage with the driving wheel, when the finger or pin tand
slot are again in a vertical line ready to engage when the table has reached the
proper height.
V represents a hand wheel provided in its hub v with an internal screw
thread which engages with an external screw thread vl formed on one of the stay
rods a which connect the side frames A. A of the machine, v³ ³ represent two
parallel plates secured to the floor and adapted to support the machine. The
feet of the side frames A A rest upon tracks formed on the plates v² and are
guided by upwardly projecting flanges formed along the inner edge of the
plates. are upwardly projecting studs or lugs formed on one of the plates v²
and arranged on opposite sides of the hub of the wheel V, whereby the wheel is
confined between the studs and prevented from moving longitudinally over the
screw thread v¹. By turning the wheel V in one or the other direction the
threaded hub v engaging with the screw thread v¹ causes the machine to be moved
longitudinally on the plates v2, whereby the position of the machine can be adjusted
with reference to a ruling or other machine which receives the paper from the
feeding machine.
The operation of the machine is as follows that is to say, the pile of paper
being placed upon the feed table A¹, the finger F, buckling fingers H 1, foot J and
the feeding fingers M M all rest upon the top sheet. The forward movement of
the buckling finger H draws the corner of the top sheet from under the finger E
and buckles the corner of the sheet against the roller of the finger I, thereby
separating the top sheet from the pile. The fingers H and I on their. return
movement are raised from the separated sheet by the finger F and ride upon the
latter. The tension rod G is released at the same time by the action of the cam g'
on the lever G, and these parts add their combined pressure to that of the finger F,
thereby holding the latter tightly upon the pile of paper.
The foot J is now lifted from the top sheet by its actuating mechanism and the
fingers A begin their forward movement and cause the top sheet to move toward
the rollers P and P¹ until the latter grip the front edge of the top sheet. The
sheet is then fed forward by the rollers P P¹ upon the carrying tapes. After the
fingers M M have completed their forward movement they are brought back by
the action of the grooved cam N¹, and connecting parts, and when they have
reached the limit of their backward movement they remain at rest upon the top
sheet, until the buckling device has again moved forward and buckled the top
sheet. When the buckling fingers have returned and rest upon the top of the
finger F, the feeding fingers M again begin their forward movement and carry
the top sheet between the rollers P P', and so the movements of the parts continue
until the last sheet has been fed from the table A', when the pawl u drops into
the slot in the table and engages against the lever ³ and thereby shifts the
clutch mechanism and stops the movement of the machine.
In Figures 17 to 33, which represent the improved machine suitable for use in
connection with a printing press, the stationary frame A of the machine may be
attached to the frame of a printing press in such manner that the machine takes
the place of the ordinary feed board, as illustrated in Figure 17, in which A
represents the cylinder of the press, a¹º represents the horizontal driving shaft of
the machine arranged transversely at the rear end of the frame A and journalled in
bearings a secured thereto. B10 is a sprocket or chain wheel mounted loosely on
one end of the driving shaft a¹ and connected with a similar wheel on the shaft of
the press cylinder, or other shaft from which power is derived by the drive chain 6*0.
The chain wheel B10 is connected with the shaft a by a sliding bolt 6ª¹ which is

page_text: attached to the wheel B and engages with a ratchet wheel 23 secured to the
shaft al. This ratchet wheel is provided with a single tooth, so that when the
feeder is connected with the printing press, the feeder will always start at a given
point with reference to the press.
A¹ represents the table upon which the pile of paper is placed and which is sup-
ported by downwardly extending rack bars c which engage with pinions c". The
latter are mounted on horizontal shafts c¹ arranged underneath the table parallel
with the driving shaft a¹ and journalled in bearings secured to the main frame A.
The rack bars co are held in contact with the wheels c" by guide caps c¹³ which are
hung on the shafts c and bear against the rear sides of the rack bars, as repre-
sented in Figures 26 and 27. 10 represents a counter-shaft arranged on one side
of the main frame A at right angles to the shafts c¹ and below the same. repre-
sents worms secured to the shaft d¹º and engaging with worm wheels d¹² secured to
the ends of the shafts c¹², whereby motion is transmitted from the shaft d to the
shafts c. The shaft d¹ is journalled in bearings №13 secured to the main frame.
E10 represents a ratchet wheel secured to the rear end of the shaft d¹º and e¹º.repre-
sents an actuating pawl which engages with the ratchet wheel E10. The pawl elo is
attached to the end of an arm ell which is mounted loosely on the shaft do near the
driving shaft a¹ and which is actuated by a cam e¹ mounted on the end of the
shaft a The arm ell is provided with a nose or projection which engages against
the face of the cam el, as represented in figures 19 and 28, so that the arm e¹ is
moved by the cam e12 in the direction in which the pawl 10 slides over the ratchets
of the wheel E¹, and gives no motion to the same, as represented by the arrow in
Figure 28. f represents a spiral spring which is secured with one end to the hub
of the arm ell and attached with, its other end to an adjusting rod f" on which it
is adjustably held by a thumb-nut f12, by which the pressure of the spring can be
regulated. The rod f¹¹ is secured to one of the bearings all or to some other part
of the machine. The spring f10 presses the arm 6 against the cam e¹³ and causes
the arme to swing toward the cam as the arm is released by the cam, so that a
rocking movement is imparted to the arm ell in one direction by the cam e12, and
in the other direction by the spring f10. The movement of the arm ell produced by
the spring f10 takes place in the direction in which the pawl elo engages with the
ratchets of the wheel E10 and turns the latter so that the motion of the wheel E¹º
and of the shaft 10, and shafts c2 is produced by the pressure of the spring f10,
while the cam e¹² merely serves to swing the arm el backward and place the
pawl in position to begin its operative movement. The motion which is pro-
duced by the spring f10 in the shafts c¹ causes an upward movement of the rack
bars c and table A¹.
Go represents the bolding-down finger arranged near one corner of the pile of
paper and attached to a spring bar glo which is secured with its forward end to a
cross piece gll of the main frame. Ho represents the gauge finger arranged to bear
upon the paper in front of the holding-down finger G10 and attached to a spring
bar 10 which is secured with its front end to the cross piece g". The rear ends of
the spring bars g¹º and h¹º are connected respectively by rods g¹ and h¹² with cams
g and secured to the driving shaft a¹º. The lower ends of the rods 12 and g¹²
are constructed in the form of open frames or heads g and h¹ which enclose the
cams ghs. The spring arms go ho hold the frames g h against the under
sides of the cams gl³ ³, so that the downward movement, of the spring bars is
produced by the cams, while their upward movement is produced by their elasticity,
which causes the frames gh to follow the cams during their upward movement.
The frames gare guided in a block I which is arranged between the frames
and provided with upright ways in which the frames move. The cam g¹³ is formed
ou a sleeve I which is secured to the shaft a10 by a set screw 220, and the cam 13
is secured to the sleeve I¹¹ by a set as clearly represented in figure 24, so that these
cams and parts connected there with can be adjusted on the shaft a by simply
releasing the set screw 1. The cams g¹s and h¹³ are so formed as to alternately
raise and lower the holding-down finger G10 and the gauge finger H1, both fingers

page_text: being down on the paper an instant before either rises. The front ends of the
arins go ho are laterally adjustable on the cross piece 9" in order to adapt the
fingers and their actuating parts to the width of the pile of paper.
The holding down finger G¹º performs the double function of holding the pile with
a strong pressure when the gauge finger is raised and also holding the top shect with
a light pressure in separating the top sheet from the pile. In order to accomplish
this, the finger G10 is attached to the lower end of a rod ko which slides vertically
in the lugs of a carrier K10 which latter is secured to the spring bar g⁰ as repre-
sented in figures 29 and 30. The rod 10 is pressed downwardly by a light spring l
which is attached with one end to the carrier K10 and with its other end to the
rod 10 12 is a vertical set screw which is attached to the carrier K10 and
terminates a short distance above the finger G. When the spring bar gl⁰ is
lowered by the cam g¹³ the lower end of the set screw strikes upon the
finger G and presses the latter downwardly against the paper, thus securely holding
the pile with a strong pressure. When the spring bar g10 is raised, so that the set
screw is raised from the finger G, the latter is lightly held down upon the
paper by the spring . By adjusting the set screw 12 the precise point at which
the strong pressure is applied to the finger Go is nicely regulated. The carrier K¹
is provided with a vertical slot 13 through which the spring bar to passes. The
finger Go is attached to the rod 10 by a pivotal joint ¹, the pivots standing at
right angles to the length of the bar g10, the lower end of the rod 10 being
bifurcated to straddle the upper end of the finger Go. The upper pivotted end
of the finger G10 is provided at its front side with a shoulder which bears against
the rod when the finger Go is in an upright position and which prevents the
finger Go from swinging forwardly beyond its upright position, while the finger is
free to swing backwardly.
k is a light spring which is secured to the lower end of the rod 10 and bears
with its lower end against the finger G10, tending to hold the latter in an upright
position, but permitting the finger to yield rearwardly under a pressure. By this
means the finger is allowed to yield backwardly as the bar g10 is lowered and
prevented from assuming a forwardly inclined position with reference to the surface
of the pile of paper, which it would do if the finger G10 were rigidly attached to the
bar glo, owing to the curvilinear movement of the finger by reason of the bar g¹º
being substantially a pivotted bar. This slight curvilinear movement would cause
a rigid finger to work the pile gradually forward out of place, and this is prevented
by rendering the finger backwardly yielding as above described, because the joint
in the finger permits the latter to maintain a vertical position on the pile
irrespective of the movements of the bar 910. The carrier K¹0 is adjustably
secured to the bar g10 by set screws k¹6.
The gauge finger H10 is attached to a carrier L10 by means of a vertical screw
shank which works in a threaded opening in the carrier and is clamped on the
same by a thumb nut ". The shank is provided at its lower end with a
ball which engages in a spherical socket in the finger H, thereby rendering the
finger yielding in all directions and permitting the finger to adjust itself to the
uneven or wavy surface of the pile. The finger H is held in an upright position
by an elastic sleeve ¹s of rubber or coiled wire which surrounds the finger and the
lower portion of the shank 10, and permits the finger to yield, but holds the finger
substantially in an upright position in the absence of any disturbing force. The
lower end of the finger H¹ is faced with a rubber block which affords a firm
bearing on the paper. The carrier L¹º is adjustably secured to the bar h¹o by a set
screw The gauge finger H10 resists the upward movement of the pile and this
resistance is transmitted through the rack bars 10, wheels c, d d shaft d¹º,
ratchet wheel E¹o, pawl e¹ and arm ell to the spring f10 which latter tends to feed
up the pile against the gauge finger H¹, so that by. increasing or reducing the
pressure of the spring f10, the feed is increased or reduced.
M10 represents the buckling finger whereby the top sheet is buckled against the
gauge finger,Ho and separated from the pile. The buckling finger is provided at

page_text: 'its front end with a roller which bears upon the paper and a stop device whereby
the roller is prevented from rotating during the forward movement of the finger
and permitted to rotate during the backward movement of the finger, as herein-
before described. M₁ represents a rock, arm whereby the buckling finger M10 is
actuated. This arm is mounted loosely upon a horizontal shaft or rod m10 which
is arranged parallel with the driving shaft 10 below the main frame A. The
upper end of the rock arm M¹ is provided with an extension M¹² to which the
buckling finger M10 is adjustably attached by a bolt 11 passing through a slot m¹
in the extension M¹, whereby the throw of the buckling finger can be increased or
reduced. The rock arm Mu is swung forwardly by a cam m¹s secured to the
driving shaft a¹ and backwardly by a spring m¼” The throw of the rock arm Mu
is regulated by an adjustable stop m¹s which is secured to the rock arm and comes
in contact with the main frame A, thereby determining the initial position of the
rock arm.
The body of the buckling finger M is composed of a coiled spring m16
which tends to hold the roller of the buckling finger down upon the paper and at
the same time permits the roller to assume an inclined position laterally in
adjusting itself to the uneven surface of the paper. The extension M¹ª is attached
to the rock arm M by a bolt m¹ on which the extension M¹ can be adjusted so as
to regulate the position of the buckling finger on the paper and the operative length
of the rock arm by which the buckling finger is moved..
N10 N10 represent the feeding fingers provided at their front ends with rollers
like the rollers m previously described and attached with their rear ends to the
rock arm N which are mounted loosely on the shaft m10 and swing forwardly by
cams no secured to the driving shaft a¹ and backwardly by springs n¹¹.
When the buckling finger M10 moves forward to separate the top sheet the
holding down finger G is raised and bears upon the corners of the pile with a
slight pressure. When the top sheet has been separated, the holding-down finger
is lowered and presses upon the corner of the pile with a heavy pressure thereby
holding the pile in place. The gauge finger H is next raised to release the top
sheet and the feeding fingers N10 then move forwardly and remove the top sheet.
010 represents a duplex spring which is arranged between the table A' and the
stationary frame A and rests with its lower arms upon the frame A and with its
upper arms against the table A', as represented in Figures 17 and 18. This spring
exerts an upward pressure against the table A¹ which is adjusted sufficiently to
compensate for the weight of the pile and which grows less as the spring becomes
expanded in raising the table in the same measure as the weight of the pile is
reduced by feeding off the paper.
The spring 10 substantially relieves the parts which feed the table from the
weight of the pile of paper and thereby renders the feeding mechanism more
sensitive to the changes which take place in feeding off the paper.
P10 represents the lower feed roller arranged between the front portion of the
main frame A and having its shaft po journalled in bearings formed in said
frame. P represents the upper feed rollers which rest upon the lower roller P¹º.
The latter is provided with annular grooves in which run the feed or carrying
tapes q which run around the tail roller qll. The roller q is journailed in a
frame Q which is hung loosely upon the shaft p10 of the lower feed roller, so that
the frame Q10 can be turned on the shaft p10 as an axis. The upper feed rollers P¹º
are journalled in side bars q₁ which are pivotted at their lower ends to the
frame Q10 710, 11 are cross bars which connect the side bars of the frame Q10 near
their front and rear ends.
S10 represents travelling endless guide belts arranged on the inner sides of the
side bars of the frame Q10 to guide the paper as it passes over the tapes q¹º. Each
endless belt S10 runs around two pulleys or wheels s¹0, s which turn on studs
secured to longitudinal bars s¹². The latter are adjustably. secured with their front
ends to the cross bar 10 and with their rear ends to the cross bar 11. Each roller 811
is rotated by an endless cord 813 which runs around a grooved pulley formed at
the lower end of the roller s, and around the lower feed' rollers P10 from which

page_text: the endless cord s¹³ derives its motion, in such manner that the inner portion of
each endless belt S10 runs in the direction in which the paper moves over the
tapes q10. The endless cord is half twisted and guided by a grooved roller 8¹³
attached to the longitudinal bar 81, as represented in Figure 20. The tapes g¹º
may be arranged slightly obliquely toward the endless bolt So against which it is
desired to feed the paper. The lower feed roller P1 is driven from the driving
shaft a by an endless belt to running around pulleys T10, T1 secured respectively
to the driving shaft a¹ and the shaft of the feed roller P¹º
It will be seen that all the parts of the feeder are driven from the driving
shaft al. The tail roller q" delivers the paper to the printing press or other
machine with which the feeder is connected. By engaging a hook U with the
tail roller q or some other part of the movable frame Q10 as represented by
dotted lines in Figure 17, the frame Q10 and the parts supported on the same
can be raised up when it is desired, to have access to the cylinder of the
printing press for making ready or to such other machine with which the feeder
is connected.
The feeding fingers N10 N10 move forwardly until the front portion of the top
sheet is firmly seized by the feed rollers P10 Pl The latter then move the sheet
forwardly upon the tapes and the tapes convey the sheet onward and register the
sheet against one or the other of the travelling side guides S. The travelling side
guides can be adjusted toward or from the sides of the frame Q10 by adjusting the
bars s¹ on the rods 10, 11
The buckling finger M10 and the feed fingers N10 have a rectilinear reciprocating
movement in the same direction on the pile, whereby the lateral displacement of
the top sheet is avoided and the actuating mechanism of the fingers is greatly
simplified.
