The adjustment of the bed and platen is provided for as follows, that is to

inking rollers & dwell first upon one inking cylinder, then pass over the form,
then dwell upon the second inking cylinder, and pass back again over the form,
so that the form rollers are inked upon each side of the form and supply ink to
the form, first from top to bottom and then from bottom to top. This ensures the
perfect distribution of ink over the form.

The mechanism for moving the form-rollers consists of the connecting rod,
jointed at one end to the frame A, and carrying at the other end a wrist pin
and friction roll (see Figure 1) which passes through the slot in one arm of the
lever e, and also through the cam slot in one side piece of the frame B. By
this arrangement the lever remains motionless during the first portion of the
"movement of the frame B towards frame A, that is, until the roll or stud on
rod has traversed the upwardly inclined part of the cam sloi, and also
"remains motionless during the latter part of the movement of frame B
"towards frame A, and so of the first and last portions of the movement of the
frame B away from the frame A and as lever carries the form inking-rollers.
these rollers dwell upon the inking cylinders e, e, while lever is motionless and
pass over the form when lever moves on its axis, which is the shaft . The
፡፡ cross rod serves to connect the lever on one side of the frame B with a
corresponding lever on the other side of that frame; this mechanism also
"constitutes a feature of my Invention. The form-inking rollers are supported
in yokes, and these yokes are jointed to the ends of sliding rods which slide in
ways in the lever ef as indicated, the springs on the rods serve to hold the rollers
close against the inking cylinders and the form, all of which will be clear from the
Drawings without further description.
"
The paper or other material to be printed upon is in a roll, supported on the
"shaft, and the end of the sheet is passed from the roll to the slacking
feed d, e, the function of which is to draw the sheet from the roll so as to leave
it slack between the roll and the intermittent feed by which the sheet is brought
over the platen ready to receive the impression, and is carried from the platen
"after the impression.

"
This slacking fee. 2, is controlled by the cone-pulleys d³, d', in order that
"the rate of feed may be readily changed. The belt connecting these cone-
pulleys passes through the belt-shipper and this shipper is moved by revolving
the shaft in this way the feed 7, № is under complete control, and its rate
may be changed at any time.

"The sheet passes from the slacking feed ', . over a guide , then over the
platen through the ruling or bronzing apparatus (if it is to be ruled or bronzed)
and through the main feed to the cutter blades (if it is to be cut.).
The main feed mechanism consists of a pair of rollers f, f', one of which is
intermittently rotated by means of a clutch mechanism, one member of which is
fast to it; the other member of this clutch mechanism can revolve freely in one
direction without moving the feed roll f', but when revolving in the other
direction it engages that member of the clutch mechanism which is fast to the
roll, and thereby revolves the said roll f' and feeds the sheet.
"This part of the clutch mechanism is the pinion and its discs, and the
pinion is revolved by the rack f. This rack is journalled to a block which
is held in the slot of a casting by means of an adjusting serew, by which the

page_text: "
"distance of the journal of the rack from the centre of the wheel can be
" accurately adjusted, and thereby the throw of the rack falso accurately adjusted;
and as the throw of this rack determines the length of the sheet fed, the main
"feed is also accurately adjusted. The casting is secured to the wrist pin b
"and therefore moves as a part of the wheel bª.
"
"
"
"It is easy to so adjust the rack that its throw shall give very nearly the
exact length of feed desired, but when an exact register is required (as for instance
"in printing a roll of paper, one side of which has been already printed on the
machine) it is essential that the feed should be still more accurately adjustable
in order to preserve the register throughout: this is accomplished by means of the
contrivance now to be described. The notched wheel is fast to the feed roll f¹.
and this notched wheel is so arranged with relation to the locking device g'
"that after the rack has ceased to move feed roll f, the locking device
"is forced into one of the notches on wheel g. The throw of the rack f is'
adjusted so that a notch in the wheel is always brought into such relation
"with the locking device that the latter will enter the notch, and when forced
"home will move the wheel g slightly.
65
"
8
"
"
"Without this adjusting feed device any ill adjustment of the throw of rack f',
or any lost motion of the clutch device, however slight, would accumulate: thus
"if the main feed fed the sheet even one hundredth of an inch too little
or too much the error would be one half inch (in case of printing the other
"side of a sheet already printed on the machine) after fifty impressions; but with
"the adjusting feed any error in the main feed will be remedied at each impression.
because the main feed-will-always leave the proper noich in the wheel in such
"relation to the locking device or wheel that it will enter the notch, and when
forced home will bring the said wheel, and with it the feed roll f. into the
exact position required. Moreover the feed is easily altered within the slight
"limits which are requisite by moving the locking device slightly, and this can be
"done while the machine is running. Suppose, for example, a sheet already
printed on one side by the machine is put in to be printed on the other side, and
"it is found that the register is not so exact as it should be, then the locking
"device g' is moved slightly towards or from the axis of the lever by means of
"the screw; this will slightly alter its relation to the notch in the wheel g left
nearest it by the rack and thereby slightly increase or diminish the length of
"the sheet fed. After each impression the lever is actuated by means of the
rod g, which is jointed to the slide through which the rack plays, a check
"nut prevents any accidental motion of screw . This adjusting feed is an
important part of the said Invention.
"
"
"
"It is possible to adapt a press in which the platen moves towards and from
"the hed for use with a roll of paper or other material, as above described,
especially if the slacking feed, main feed, and adjusting feed be used, but the
form of machine shewn is more desirable, as the paper moves readily over the
stationary platen without special appliances, which would be required if it were
"fed over the bed or over a moving platen.
"
"
"Another and the main feature of the Invention consists in a bed and platen
printing press, in which a long sheet of paper or other material, many times
longer than the length of each impression, is used, constructed substantially as
"described, that is to say, with feed mechanism on each side of the platen. the
"mechanism for slacking the paper adjustable in its rate of feed substantially as
"described, and the other mechanism for feeding the paper to and taking it from
"the platen, also adjustable substantially as described.

"The cutter and the main feed mechanism are supported by a sliding frame h.
and this frame is moved by the screws which are revolved from the shaft h³,
as clearly shewn in the Drawings. To admit of this adjustment of the cutter
"frame the connecting rod is jointed to a sliding arm on the rock shaft 75, and
"this rock shaft is made square (or provided with a spline). so that its arm may
move freely lengthwise of the shaft. This rock shaft 5 is moved on its axis by'

means of an arm 7ª and a cam groove . This combination of the frame
carrying the cutter and main feed mechanism with means for adjusting its position
on the main frame, and with mechanism for actuating the cutter blade, so
constructed as not to interfere with the adjustment of the frame 4, also constitutes
11 one feature of this Invention.

The apparatus for supplying ink to the distributing cylinders consists of ink
"fountains of ordinary construction, the rolls of which supply ink in the feeders.
The operation is as follows, that is to say:

"Starting with the machine in the position shewn in Figures 1 and 2 the
continued revolution. of the main shaft 1 (which is supplied with the usual fly
wheel and pulleys, not shewn in the Drawings) revolves shaft in the direction
"of the arrow on wheel in Figure 2, and thereby draws the frame B towards-
"the frame A; the motion of frame B towards the frame A causes the roll or stud
on the end of rod to traverse the cam slot and thereby move the form
inking rolls over the form from inking cylinder to inking cylinder c.
The
impression is made when the wrist pins pass their dead point. Before the
impression is made the main feed has ceased to feed the sheet, and been locked
by the adjusting feed (see Figure 7), but soon after the wrist pins & pass their
dead point the rack begins to move the main feed, and the feed lakes place
while frame B is moving away from frame A. and during this time the form
inking rollers are moved over the form from inking cylinder to inking
" cylinder .

The inking cylinders are revolved as follows:-The gear wheel on shaft D
meshes with the gear wheel j', which is on a stud supported by links and
these links serve to hold the stud of the gear wheel always at the same
distance from the shaft D and the shaft of the gear wheel ♬, thereby permitting
"the forward and backward movement of the bed frame B.
There is a gear wheel on the shaft which meshes with a gear wheel on the
inking cylinder c', and that cylinder is geared to the cylinder by intermediate
gear wheels: a pulley on shaft with a belt to a pulley on shaft 1) and a second
belt to a pulley on shaft will answer in place of the gear wheels j. j, j³, und

The feeder or roll which carries ink from the fountain roll to the inking
eylinder is actuated as clearly shewn in Figure 1, where k represents the fountain,
"the fountain roll, the feeder. The shaft of the feeder is mounted in the
"forked ends of levers, which are supported on a shaft ; a rod passes through
"the lower end of the lever and is journalled at its other end to a cross rod
"fast to the frame A. The connecting rod from the lever to the corresponding
"lever which supports the upper feeder causes both feeders to more alike. When
the bed frame B is out, as represented in Figure 2, the end of the lever brings'
up against a collar on rul, and the feeders are thereby forced against the
fountain roll, and at the same time the fountain rolls are worked by pawls
on the feeder levers, taking into ratchet wheels on the shaft of each fountain
roll.

The apparatus for ruling and cross ruling is shewn in side views in Figures 1
and 2, and in plan in Figure 8.
The lines lengthwise of the strip are made by a proper number of ruling
pens supported upon a cross bar which is adjusted by the screws to give
"the proper pressure of the points of the pens upon the paper. These pens are
supplied with ink in the usual manner. The ruling is effected by the motion of
the paper under the pens. For cross-ruling the holder which carries the
proper number of pens, must be drawn across the paper; this holder is hinged
to the carriage, and this carriage is moved back and forth across the sheet of
paper by any suitable mechanism. A cheap and convenient mechanism for this
purpose is that shewn in the Drawings. consisting of a cord attached to some
moving part of the machine, so that the carriage will remain at rest until the
paper is stationary, and then be drawn across the paper; a cord 1, with a weight
86
"
፡፡

page_text: "
"
on its lower end, serves to draw the carriage back; this weight is in the tube F.
The cross-ruling pens must be pressed upon the paper to rule and be lifted when
"the carriage returns, and also when the cross-ruling is to be interrupted.
The first pull upon cord Fiends to depress the holder P, as shewn in Figure 15,
"which is a detached view for illustration of the carriage and its adjuncts:
“further motion of the cord ♬ draws the carriage across the paper. The arm is
"fast to the holder, and rides on suitable stops P, and the pens are thereby
"lifted from the paper: these stops are adjustable and are arranged properly to
interrupt the crust ruling as desired. When the cord is slackened the cord F
and its weight will first lift the pens from the paper, as will be clear from
Figure 15, and then draw the carriage back ready for the next cross wise
"
movement.
"The bronzing attachment consists of a close box with a hopper at one end;
one side of this hopper is a plate m. of thin metal, the bottom edge of which
can be nicely adjusted by set screws with relation to the roll, which forms
the bottom of the hopper; the bronzing powder is put into this hopper and is
delivered from it by the revolution of the roll m³, the quantity delivered depending
upon the adjustment of the plate m. The bronze falls upon the fur-covered
"roll, which is also revolved, and is deposited by that roll upon the paper
"which lies between that roll and the cross bar m. The paper enters the box
through a slit, as shewn, and this slit is preferably lined with fur to prevent
waste of bronze. One or more polishing rolls may be used to polish the bronze
"and remove any excess. The brushing beli is a fur covered belt which moves
across the paper--and carries off any loose bronze into the drawer at the
"bottom of the box. This hell also als in-polishing the bronze. The polishing
rolls should revolve rapidly to get a fine polish on the bronze. The bronzed
paper leaves the box through a second slit. also lined with fur. The bronze
is closely confined within the box; all waste falls into the drawer ready for use
again, and the bronze which adheres to the paper is polished, the whole operation
of bronzing being not only performed automatically but much better and with
"less waste than it can be done by hand. One of the pulleys which carry the
brushing belt is driven by bevel gear wheels from the shafi of one of the rolls mn",
and the rolls m³ and m² are geared together, being also geared to m². One of
these rolls is revolved in any suitable manner in practice by a pulley on the shaft
"connected by a beli with a pulley on the driving shaft D.

page_text: LETTERS PATENT to William Robert Lake, of the Firm of Haseltine, Lako,
& Co., Patent Agents, Southampton Buildings, London, for an Invention of
"IMPROVEMENTS IN PRINTING MACHINERY, AND IN APPARATUS FOR RULING
AND BRONZING, AND FOR CUTTING PAPER OR OTHER LIKE MATERIAL.”
A communication from abroad by Wellington Parker Kidder, of Boston,
Massachusetts, United States of America.
PROVISIONAL SPECIFICATION left by the said William Robert Lake at
the Office of the Commissioners of Patents on the 7th July 1880.
WILLIAM ROBERT LAKE, of the Firm of Hasoltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN PRINTING MACHINERY, AND
IN APPARATUS FOR RULING AND BRONZING, AND FOR CUTTING PAPER OR OTHER
LIKE MATERIAL." [A communication from abroad by Wellington Parker Kidder,
of Boston, Massachusetts, United States of America.]
This Invention relates to printing machinery, and to apparatus for ruling and
bronzing, and for cutting paper or other like material.
In carrying the said Invention into practice I provide a main-frame and
bed-frame which are connected together by a rod, so that the bed-frame can swing
towards and from the main frame on the said rod as an axis. The platen is
supported adjustably upon the main frame, and the bed is carried by the bed-
frame. The latter is vibrated on its axis by connecting rods, and these rods are
connected at one end of each to journals, which are formed excentrically upon the
ends of a shaft. This shaft is mounted in proper boxes in the bed-frame. The
other ends of the connecting rods are attached to wrist-pins on wheels, both of
which are fast to a shaft which is mounted in proper boxes in the main framo.
Consequently when the last named shaft revolves the bed-frame is moved on its
axis towards and from the main frame, and the form of type carried by the bed-
frame is pressed upon the paper supported by the platen.
The bed is
The adjustment of the bed and platen is provided for as follows:-Tho platon is
adjustable on the main frame by means of four screws, each of which has upon it a
collar; these scrows enter the main-frame, and the platen rests upon the collars
The platen is held down upon the collars by means of screws.
adjustable by means of its shaft, as the relation of the bed-frame and main frame
can be altered to a small extent by turning this shaft, which is turned by means of
a handle which is fast to the said shaft. On this handle is a catch which fits into

page_text: one of the notches provided on a casting, which is also capable of adjustment by
means of a screw which turns in a nut secured to one of the connecting rods; this
casting is supported upon the journal of the shaft as an axis. By these means the
bed and platen can be adjusted with extreme accuracy, and the impression be made
perfect over all parts of the form.
There are two inking cylinders each provided with the usual fountain, feed-roll,
distributing roll, and feeder roll The form lies between inking cylinders, and the
form-inking rollers dwell first upon one inking cylinder, then pass over the form,
then dwell upon the second inking cylinder, and then pass back again over the
form, so that the form rollers are inked upon each side of the form, and supply ink
to the form first from top to bottom, and then from bottom to top; this ensures the
perfect distribution of ink over the form.
The mechanism for moving the form-rollers consists of a connecting rod jointed
at one end to the main frame, and carrying at the other end a wrist-pin and friction
roll, which passes through the slot in one arm of a lever, and also through a cam slot
in one side pieco of the bed-frame. By this arrangement the lever remains
motionless during the first portion of the movement of the bed-frame towards the
main frame, that is to say, until the stud on rod has traversed the upwardly
inclined part of the cam-slot; and also remains motionless during the latter part of
the movement of the bed-frame towards the main frame; and so of the first and
last portions of the movement of the bed-frame away from the inain frame; and
as the lever carries the form-inking rollers, these rollers dwell upon the inking
cylinders while the lever is motionless, and pass over the form when the lever
moves on its axis; a cross rod serves to connect the lever on one side of the bed-
frame with a corresponding lever on the other side of that frame. This mechanism
also constitutes one feature of my Invention.
The form-inking rollers are supported in yokes, and these yokes are jointed to
the ends of sliding rods which slide in ways in the lever; the spring on the rods
serve to hold the rollers close against the inking cylinders and the form.
The paper or other material to bo printed is in a roll supported on a shaft, and
the end of the sheet is passed from the roll to a slacking feed, the function of which
is to draw the sheet from the roll so as to leave it slack between the roll and tho
intermittent feed, by which the sheet is brought over the platen ready to receive
the impression, and carried from the platen after the impression. This slacking
feed is controlled by cone-pulleys in order that the rate of feed may be readily
changed. The belt connecting these cone-pulleys passes through a belt-shipper,
and this shipper is moved by revolving a socond shaft; in this manner the feed is
under complete control, and its rate may be changed at any time. The sheet
passes from the slacking feed over a guide, then over the platen through a ruling
or bronzing apparatus (if it is to be ruled or bronzed), and through the main feed
to cutter blades (if it is to be cut).
The main feed mechanism consists of a pair of rollers, one of which is inter-
mittently rotated by means of a clutch-mechanism, one incmber of which is fast to
it; the other member of this clutch-mechanisın can revolve freely in one direction
without moving the lower feed-roll, but when revolved in the other direction it
engages that member of the clutch mechanism fast to the roll, and thereby revolves
it and feeds the sheet. This part of the clutch-mechanism consists of a pinion and
disc, and the pinion is revolved by a rack. This rack is journalled to a block which
is held in a slot of a casting by means of an adjusting screw, by which the distance
of the journal of the rack from the centre of a wheel which is provided can be
accurately adjusted, and thereby the throw of the rack also accurately adjusted ;
and as the throw of this rack determines the length of sheet fed, the main feed is
also accurately adjusted. The casting is secured to the wrist, and therefore moves
as a part of the wheel. It is easy to so adjust the rack that its throw shall give
very nearly the exact length of feed desired; but when an exact register is to be!
obtained (as for instance, in printing a roll of paper, one side of which has been
already printed on the machine), it is essential that the feed be still more accurately

page_text: adjustable in order to proserve the register throughout. This is accomplished by
means of the contrivance now to be described. A notched wheel is fast to the feed-
roll, and this notched wheel is so arranged with relation to a locking device that
aftor the rack has ceased to move tho feed roll the locking device is forced into one
of the notches on the notched wheel. The throw of the rack is adjusted so that a
notch in the wheel is always brought into such relation with the locking devico
that the latter will enter the notch, and when forced home will move the wheel
slightly. Without this adjusting feed-device any ill adjustment of the throw of
the rack, or any lost motion of the clutch-device, however slight, would accumulate;
thus if the main feed fed the sheet even one hundredth of an inch too little or too
much, the orror would be one half an inch (in case of printing the other half of a
sheet already printed on the machine) after fifty impressions. But with the
adjusting feed any error in the main feed will be remedied at each impression,
because the main feed will always leave the proper notch in the wheel in such
relation to the locking device that the wheel will enter the notch, and when forced
home will bring the wheel, and with it the feed-roll, into the exact position
required. Moreover, the feed is easily altered within the slight limits requisite by
moving the locking device slightly, and this can be done while the machine is
running. Suppose, for example, a sheet already printed on one side by the machine
is put in to be printed on the other side, and it is found that the register is not so
exact as it should be; then the locking device is moved slightly towards or from
the nxis of its lever by means of a screw; this will slightly alter its relation to the
notch in the wheel left nearest it by the rack, and thereby slightly increase or
diminish the length of the sheet fod after each impression. The lever is actuated
by means of a rod which is jointed to a slide through which the rack plays.
A check-nut prevents any accidental motion of the scrow. This adjusting feed is
an important part of the said Invention.
It is possible to adapt a press in which the platen moves towards and from the
bed for use with a roll of paper or other material as above described, especially if the
slacking feed, main feed, and adjusting feed be used; but the form of machine
shown is more desirable, as the paper moves readily over the stationary platen
without special appliances, which would be required if it were fed over the bed or
over a moving platen.
Another and the main feature of this Invention consists in a bed and platen
printing press, in which a long sheet of paper or other material many times longer
than the length of each impression is used, constructed substantially as described,
that is to say, with feed mechanism on each side of the platon, mechanism for
slacking the paper adjustable in its rate of feed, substantially as described, and
other mechanism for feeding the paper to and taking it from the platen, also
adjustable, substantially as described.
The cutter and the main feed mechanism are supported by a sliding frame, and
this frame is moved by screws which are revolved by a shaft. To admit of this
adjustment of the cutter frame a connecting rod is jointed to a sliding arm of a
rock shaft, and this rock shaft is made square (or provided with a spline) so that
its arm may inove freely lengthwise of the shaft. This rock shaft is moved on its
axis by means of an arm and cam groove. This combination of the frame carrying
the cutter and main feed mechanism, with means for adjusting its position on the
main frame, and with nechanism for actuating the cutter blade, so constructed as
not to finterfere with the adjustment of the frame, also constitutes one feature of
this Invention.
The apparatus for supplying ink to the distributing cylinders consists of ink-
fountains of ordinary construction, the rolls of which supply ink to the feeders.
The inking cylinders are revolved as follows:-A gear-wheel on the driving
shaft meshes with another gear-wheel which is on a stud supported by links, and
these links serve to hold the stud of the latter gear-wheel always at the same
distance from the said driving shaft and the shaft of another gear-wheel, thereby
permitting the forward and back movement of the bed-frame.

page_text: There is a gear-wheel on one of the shafts which meshes with a gear wheel on
the inking cylinder, and 'that cylinder is geared to the other inking cylinder by
intermediato gear-wheels. Pulleys and belts will answer in place of the gears-
wheels and links if desired.
The feeder or the roll which carries ink from the fountain-roll to the inking
cylinder is actuated as follows:-The shaft of the feeder is mounted in the forked-
ends of forked levers which are supported on a shaft; a rod passes through the
lower end of one lover and is journalled at its other end to a cross-rod fast to the
main frame. A connecting rod from one lover to the corresponding lever which
supports the upper feeder causes both feeders to move alike. When the bed frame
is out the end of the lever brings up against a collar on a rod and the feeders are
thereby forced against the fountain-roll, and at the same time the fountain-rolls.
are worked by pawls on the feeder-levers taking in the ratchets on the shaft of
each fountain roll.
The apparatus for ruling and cross-ruling is as follows, that is to say:―
The lines lengthwise of the strip are made by a proper number of ruling pens
supported upon a cross-bar which is adjusted by screws to give the proper pressure
of the points of the pens upon the paper. These pens are supplied with ink in the
usual manner. The inking is effected by the motion of the paper under the pens.
For cross-ruling the holder, which carries the proper number of pens, must be drawn
across the paper; this holder is hinged to a carriage, and this carriage is moved back
and forth across the sheet of paper by any suitable mechanism. A cheap and con-
venient mechanism for this purposo consists of a cord attached to some moving part
of the machine so that the carriage will remain at rest until the paper is stationary,
and then be drawn across the paper; a cord with a weight on its lower end serves to
draw the carriage back; this weight is in a tube. The cross-ruling pens must be
pressed upon the paper to rulo and be lifted when the carriage returns, and also
when the cross-ruling is to be intercepted. The first pull upon the first cord tends
to depross the holder, and further notion of the cord draws the carriage across the
paper. An arm fast to the holder rides on suitable stops, and the pens are thereby
lifted from the paper; these stops are adjustable, and are arranged properly to
intercept the cross ruling as desired. When the first cord is slackened, the second
cord and its weight will first lift the pens from the paper, as will be clear, and
then draw the carriage back again ready for the next cross wise movement.
The bronzing attachment consists of a close box with a hopper at one end; one
side of this hopper is a plato of thin metal, the bottom edge of which can be nicely
adjusted by set-screws with relation to a roll which forms the bottom of the hopper.
The bronzing powder is put into this hopper and is delivered from it by the
revolution of the roll, the quantity delivered depending upon the adjustment of the
plate. The bronze falls upon a fur-covered roll which is also revolved, and is
deposited by that roll upon the paper which lies between that roll and a cross-bar.
The paper enters the box through a slit, and this slit is preferably lined with fur
to prevent waste of bronze. One or more polishing rolls may be used to polish the
bronze and remove any excess. The brushing belt is a fur-covered belt, which
moves across the paper and carries off any loose bronze into a drawer at the
bottom of the box. This belt also aids in polishing the bronze. The polishing
rolls should revolve quito rapidly to get a fine polish on the bronze. The bronzed
paper leaves the box through a second slit also lined with fur. The bronze is
closely confined within the box; all waste falls into the drawer ready for use again,
and the bronze which adheres to the paper is polished, the whole operation of
bronzing being not only performed automatically, but much better and with less
waste than can be done by hand. One of the pulleys which carry the brushing
bolt is driven by bevel gear-wheels from the shaft of one of the rolls, and the rolls
are geared together. One of these rolls is revolved in any suitable manner in
practice by a pulley on the shaft bolted to a pulley on the driving shaft.

Southampton Buildings, London. "IMPROVEMENTS IN PRINTING MACHINERY, AND
IN APPARATUS FOR RULING AND BRONZING, AND FOR CUTTING PAPER OR OTHER
LIKE MATERIAL" A communication from abroad by Wellington Parker Kidder, of
Boston, Massachusetts, United States of America.

A represents the main frame, and B the bed-frame, which are connected by the
rod a, so that the frame B can swing towards and from the frame A on the said
rod a as an axis. The platen a¹ is supported adjustably upon the frame A, and
the bed is carried by the bed-frame B. The frame B is vibrated on its axis a by
the connecting rods b, b', and these rods are connected at one of their ends to the
journals b, b, which are formed excentrically upon the ends of shaft b³. This
shaft 6 is mounted in proper boxes in the bed-frame B. The other ends of the
connecting rods b, b', are attached to wrist pins b' on the wheels b, be, both of
which are fast to the shaft b' which is mounted in proper boxes in the main
frame A. Consequently when shaft b' revolves the bed-frame B is moved on its
axis a towards and from the main frame A, and the form of type carried by the
bed-frame is pressed upon the paper supported by the platen a'.
The adjustment of the bed and platen is provided for as follows, that is to
say:-
The platen is adjustable on frame A by means of four screws a³, each of which
has upon it a collar a³. These screws enter the frame A and the platen rests upon
the collars a³, one of the said screws with its collar being clearly illustrated in
Figure 12 of the Drawings. The platen is held down upon the collars a³ by means
of screws a*.
The bed is adjustable by means of its shaft 63, as the relation of the frame B and
frame A can be altered to a small extent by turning shaft bs. This shaft is turned

page_text: by means of handle b³, which is attached to the said shaft b³. On this handle is a
catch be, which fits into one of the notches on the casting b10; this casting is also
capable of adjustment by means of the screw b" (see Figure 2) which turns in a
nut 6 secured to the connecting rod b¹. This casting 610 is supported upon the
journal 6 of the shaft b³ as an axis; this is best shewn in Figuro 9 of the
Drawings.
By these moans the bed and platen can be adjusted with extreme accuracy, and
the impression can be made perfect over all parts of the form.
There are two inking cylinders c, cl, each provided with the usual fountain, feed-
roll, distributing roll, and feeder roll, as indicated by dotted lines near roll c in
Figure 2: The form lies between the inking cylinders c, c', and the form-inking
rollers c³ dwell first upon one inking cylinder, then pass over the form, then dwell
upon the second inking cylinder and pass back again over the form, so that the
form-rollers are inked upon each side of the form, and supply ink to the form first
from top to bottom and then from bottom to top. This ensures the perfect
distribution of ink over the form.
The mechanism for moving the form-rollers consists of the connecting rod c³,
jointed at one end to the frame A and carrying at the other end a wrist pin and
friction roll (see Figure 1), which passes through the slot in one arm of the lever c
and also through the cam slot in one side piece of the frame B. By this
arrangement the lever c' remains motionless during the first portion of the move-
ment of the frame B towards frame A, that is, until the roll or stud on rod c³ lins
traversed tho upwardly inclined part of the cam slot c³, and also remains motionless
during the latter part of the movement of frame B towards frame-A,-and so of the
first and last portions of the movement of the frame B away from the frame A;
and as lever et carries the form inking-rollers, these rollers dwell upon the inking
cylinders c, c', while lever c is motionless, and pass over the form when lever ci
moves on its axis which is the shaft b. The cross rod co serves to connect the
lever c on one side of the frame B, with a corresponding lever c' on the other side
of that frame. This mechanism also constitutes a feature of my Invention. The
form-inking rollers c are supported in yokes, and these yokes are jointed to the
ends of sliding rods, which slide in ways in the lever c' as indicated; the springs
on the rods serve to hold the rollers close against the inking cylinders and the
form, all of which will be clear from the Drawings without further description.
The paper or other material to be printed upon is in a roll supported on the
shaft d, and the end of the sheet w is passed from the roll to the slacking feed
d', d, the function of which is to draw the sheet from the roll so as to leave it
slack between the roll and the intermittent feed, by which the sheet is brought
over the platen ready to receive the impression, and is carried from the platen after
the impression.
This slacking feed d', d², is controlled by the conc-pulleys d³, d', in order that
the rate of feed may be readily changed. The belt connecting these cone-pulleys
passes through the belt-shipper, do, and this shipper is moved by revolving the
shaft ; in this way the feed d², ds, is under complete control and its rate may be
changed at any time.
The sheet w passes from the slacking feed d', d², over a guide d', then over the
platen, through the ruling or bronzing apparatus (if it is to be ruled or bronzed),
and through the main feed to the cutter blades (if it is to be cut).
The main feed mechanism consists of a pair of rollers f, f¹, one of which is
intermittently rotated by means of a clutch mechanism, one member of which is fast
to it; the other member of this clutch mechanism can revolve freely in one direction
without moving the feed roll f¹, but when revolved in the other direction it
engages that member of the clutch mechanism which is fast to the roll f, and
thereby revolves the said roll f¹ and feeds the sheet.
This part of the clutch mechanism is the pinion f and its disc f³; and the
pinion is revolved by the rack f. This rack is journalled to a block which is
held in the slot of a casting f5 by means of an adjusting screw, by which the distanco

page_text: of the journal of the rack f* from the centre of tho wheel 60 can be accurately
adjusted, and thereby the throw of the rack f also accurately adjusted; and as the
throw of this rack determines the length of the sheet fed, the main food is also
accurately adjusted. The casting is secured to the wrist pin b', and therefore
moves as a part of the wheel bo
It is easy to so adjust the rack f' that its throw shall give very nearly the exact
length of feed desired; bnt when an exact register is required (as for instance in
printing a roll of paper one sido of which has been already printed on the machine),
it is essential that the feed should be still more accurately adjustable in order to
preserve the register throughout. This is accomplished by means of the contrivance
now to be described. The notched wheel g is fast to the feed roll f¹, and this
notched wheel is so arranged with relation to the locking device g¹, that after the
rack f has ceased to move feed roll f', the locking device is forced into one of tho
notches on wheel g. The throw of the rack is adjusted so that a notch in
the wheel g is always brought into such relation with the locking device g¹ that the
latter will enter the notch, and when forced home will move the wheel g slightly.
Without this adjusting feed device any ill adjustment of the throw of rack for
any lost motion of the clutch device, however slight, would accumulate; thus if the
main feed fed the sheet even one hundredth of an inch too little or too much the
error would be one half an inch (in case of printing the other side of a sheet already
printed on the machine) aftor fifty impressions. But with the adjusting feed any
error in the main feed will be remedied at each impression, because the main feed
will always leave the proper notch in the wheel gin such rolation to the locking
device or wheel g' that it will enter the notch, and when forced home will bring the
said wheel g and with it the feed roll f¹ into the exact position required.
Moreover the feed is easily altered within the slight limits which are requisite by
moving the locking device slightly, and this can be done while the machine is
running. Suppose, for example, a sheet already printed on one side by the machine
is put in to be printed on the other side, and it is found that the register is not so
exact as it should be, then the locking device gl is moved slightly towards or from
the axis of the lever g³ by means of the screw g³; this will slightly alter its relation
to the notch in the wheel g left nearest it by the rack f, and thereby slightly
increase or diminish the length of the sheet fed after each impression. The lever
9 is actuated by means of the rod g, which is jointed to the slide through which
the rack f plays. A check nut 95 prevents any accidental motion of screw g³.
This adjusting feed is an important part of the said Invention.
It is possible to adapt a press in which the platen moves towards and from the
bed for use with a roll of paper or other material, as above described, especially
if the slacking feed, main feed, and adjusting feed be used, but the form of machine
shewn is more desirable, as the paper moves readily over the stationary platen
without special appliances, which would be required if it were fed over the bed or
over a moving platen.
Another and the main feature of the Invention consists in a bed and platen
printing press in which a long sheet of paper or other material many times longer
than the length of each impression is used, constructed substantially as
described, that is to say, with feed mechanism on each side of the platen, the
mechanism for slacking the paper, adjustable in its rate of feed substantially as
described, and the other mechanism for feeding the paper to and taking it from the
platen, also adjustable substantially as described.
The cutter and the main feed mechanism are supported by a sliding frame h, and
this frame is moved by the screws h' which are revolved from the shaft h², as clearly
shewn in the Drawings. To admit of this adjustment of the cutter frame tho
connecting rod h³ is jointed to a sliding arm ht on the rock shaft ho, and this rock
shaft is made square (or provided with a spline) so that its arm h' may move freely
lengthwise of the shaft. This rock shaft is moved on its axis by means of an
arm he and a cam groove h. This combination of the frame h carrying the cutter
and main feed mechanism with means for adjusting its position on the main frame,

page_text: and with mechanism for actuating the cutter blade so constructed as not to interfero
with the adjustment of the frame h, also constitutes one feature of this Invention.
The apparatus for supplying ink to the distributing cylinders consists of ink
fountains of ordinary construction the rolls of which supply ink to the feeders.
The operation is as follows that is to say :-
Starting with the machine in the position shewn in Figures 1 and 2, the continued
revolution of the main shaft D (which is supplied with the usual fly wheel and
pulleys, not shewn in the Drawings) revolves shaft 6 in the direction of the arrow
on wheel be in Figure 2, and thereby draws the frame B towards the frame A; the
motion of frame B towards frame A causes the roll or stud on the end of rod c³
to traverse the cam slot c³, and thereby move the form inking rolls over the
form-from-inking cylinder c to inking cylinder c The impression is made
when the wrist pins pass their dead point. Before the impression is made
the main feed has ceased to feed the sheet and been locked by tlie adjusting-feed.
(see Figure 7), but soon after the wrist pins 6' pass their dead point the rack f
begins to move the main feed and the feed takes place while frame B is moving
away from frame A, and during this time the form inking rollers are moved over
the form from inking cylinder c to inking cylinder c'.
The inking cylinders are revolved as follows:-The gear wheel j on shaft D
meshes with the gear wheel j', which is on a stud supported by links 1³, 1", and
these links serve to hold the stud of the gear wheel always at the same distance
from the shaft D and the shaft of the gear wheel, thereby permitting the
forward and backward movement of the bed frame B.
-There is a gear wheel on the shaft j' which meshes with a gear wheel on the
inking cylinder c', and that cylinder is geared-to the cylinder c by intermediate
gear wheels. A pulley on shaft a with a belt to a pulley on shaft D, and a second.
belt to a pulley on shaft j, will answer in place of the gear wheels j, j, ³, and
links.
The feeder or roll which carries ink from the fountain roll to the inking cylinder
is actuated as clearly shewn in Figure 1; where k represents the fountain, the
fountain roll, A² the feeder. The shaft of the feeder is mounted in the forked ends
of levers, which are supported on a shaft k; a rod passes through the lower end
of the lever ³, and is journalled at its other end to a cross rod fast to the
frame A. The connecting rod from the lever to the corresponding lever,
which supports the upper feeder, causes both feeders to move alike. When the bed
frame B is out, as represented in Figure 2, the end of the lever brings up against
a collar on rod 5, and the feeders are thereby forced against the fountain roll k³,
and at the same time the fountain rolls are worked by pawls on the feeder levers ³,
taking into ratchet wheels on the shaft of each fountain roll.
The apparatus for ruling and cross-ruling is shewn in side views in Figures 1
and 2, and in plan in Figure 8.
The lines lengthwise of the strip are made by a proper number of ruling pens L,
supported upon a cross bar , which is adjusted by the screws 12 to give the proper
pressure of the points of the pens upon the paper. These pens are supplied with
ink in the usual manner. The ruling is effected by the motion of the paper under
the pens. For cross-ruling the holder, which carries the proper number of pens,
must be drawn across the paper; this holder is hinged to the carriage, and
this carriage is moved back and forth across the sheet of paper by any suitable
mechanism. A cheap and convenient mechanism for this purpose is that shewn in
the Drawings, consisting of a cord attached to some moving part of the machine,
so that the carriage will remain at rest until the paper is stationary, and then be
drawn across the paper; a cord with a weight on its lower end serves to draw
the carriage back; this weight is in the tube . The cross-ruling pens must be
pressed upon the paper to rule, and be lifted when the carriage returns, and also
when the cross-ruling is to be interrupted. The first pull upon cord 1³ tends to
depress the holder, as shewn in Figure 15, which is a detached view for illustra-
tion of the carriage and its adjuncts; further motion of the cord l draws the

page_text: carriage across the paper. The arm 2 is fast to the holder and rides on suitable
stops, and the pens are thereby lifted from the paper; these stops are adjustablo
and are arranged properly to interrupt the cross ruling as desired. When the
cord is slackened, the cord and its weight will first lift the pens from the
paper, as will be clear from Figuro 15, and then draw the carriage * back ready for
the next cross wise movement.
The bronzing attachment consists of a close box m with a hopper at one end;
one side of this hopper is a plato m' of thin metal, the bottom edge of which can
be nicely adjusted by set screws with relation to the roll m², which forms the
bottom of the hopper. The bronzing powder is put into this hopper, and is
delivered from it by the revolution of the roll m³, the quantity delivered depending
upon the adjustment of the plate m¹. The bronzo falls upon the fur-covered
roll m³, which is also revolved, and is deposited by that roll upon the paper which
lies between that roll and the cross bar m. The paper enters the box through a
slit, as shewn, and this slit is preferably lined with fur to prevent waste of bronze.
One or more polishing rolls m³ may be used to polish the bronze and remove any
excess. The brushing belt ma is a fur covered belt, which moves across the paper
and carries off any loose bronze into the drawer m' at the bottom of the box. This
belt also aids in polishing the bronzo. The polishing rolls m³ should revolvo
rapidly to get a fine polish on the bronze. The bronzed paper leaves the box
through a second slit, also lined with fur. The bronze is closely confined within
the box; all wasto falls into the drawer ready for use again, and the bronze which
adheres to the paper is polished, the whole operation of bronzing being not only
performed automatically but much better, and with less waste, than it can be done
by hand. One of the pulleys which carry the brushing-belt is driven by bevel gear
wheels from the shaft of one of the rolls m³, and the rolls m³ and m³ are geared
together, m³ being also geared to m². One of these rolls is revolved in any suitable
manner, in practice by a pulley on the shaft connected by a belt with a pulley on
the driving shaft D.
