A is a base ou supporting frame made preferably in the form of a hollow casting
and presenting parallel top nils A A B is the frame of the printing-machine
comprising a base-plate B and cheeks or side frames 132 B³, respectively. The
base plate B fits at its forward and rear edge-portions upon the rails A' A² and is
provided on its under surface with stops which fit between the tails. The press
may be slid along the base to any desued position thereon and may be securely
clamped in adjusted position by means of a clamping-bar X which engages the
under sides of the rails A' A2 and connects with the bed by means of a screw-
bolt X' C is the drive-shaft which extends beyond the forward ond of the
machine and is jounaled in beaungs afforded by crooked arins A³ A4 extending
fioin the base A On the outer end-portion of the dive shaft is a hand-wheel C
and adjacent thereto is a loose sleeve C2 (see Fig 25) cariying a power-pulley C³.
At its inuc end the sleeve is enlarged and flanged to afford an annular inner
friction-surface y, which gives to the sleeve the character of a clutch-member.
Fastened upon the shaft adjacent to the sleeve C2 is a sleeve C provided at
opposite sides with short radial bs or feathers y', (see Figure 26). C is a sliding
circumferentially grooved wheel or clutch-member having a sleeve-portion y³
which fits over the sleeve C and is provided with longitudinal recesses to embrace
the bs y of the latter On opposite sides of the sleeve Care projecting ears
afloiding between then sockets y³n which are pivoted short links y carrying at
then free ends pivotal shoes y Pivotally secured at one end to the aim A³ 15
a clutch-shifting lever C which between its ends surrounds the shaft C and 18
provided with fingers 7 (see Figure 1), which extend loosely into the circum-
ferential groove of the sliding clutch-member C5. The power to dive the machine
1s applied to the pulley C³ and by movement of the lever C in one duection the
clutch-member C is forced into cngagement at its shoes y with the surface of
the sleeve C, causing the dive-shaft to rotate with the pulley. Movement of the
lever C in the opposite dnection withdraws the clutch-member Co from the sleeve
or clutch-membei C² and retracts the shoes y from the surface y causing the pulley
and sleeve C to rotate loosely upon the sbatt and the latter to remain stationary.
On the dive-shaft beyond the aim A' is a pinion t which dives the punting-piess,
as hereinafter described, and on the said shalt between its bearings are piuions t¹² t³,

page_text: respectively, of gradually increasing diameters, each adjustable longitudmany or
the shaft and provided with a set-screw for securing it in adjusted position.
Extending parallel with the shaft C, and substantially the full length of the
base A, 1s an auxiliary or counter-shaft D Journaled in the free cnd-portions of
On
the arms AA' and in a bearing-aim A' on the end-portion of the base A
the shaft D between its benings A³ A are pinions sss of gradually
increasing diameter and adapted to engage, respectively, with the pinions (2,

set-sciews for secuing them in adjusted position The pinions afford adjustable
speed-altering gears between the shafts C and D
}
Tho sides BB of the fiame of the printing-piess are bolted to the base-plate B¹
and strengthened by means of a cross-bar B The rear upper ends of the sides
aflord bearings for a round bar or shaft B on which its pivotally monuted a platen-
carrying jaw or frame E The frame E is formed with a body-portion or plate E¹
and parallel arched side bars E affording backward extending nims at the ends
of which the frame is pivoted upon the shaft 135 At the forward ends the
bars E are adapted to fit and rest upon su faces at the upper for ward ends of
the side-frames. At the ront ends of the aims E2 are backward extensions E³.
Pivotally connected at their upper ends to the extensions are spiral springs E,
which at their lower ends are connected with lugs upon the rent edge of the
base plate B'. On the side frames in the relative positions shown are backward
extending cars or stops and on the side-bars E are laterally extending cars ol
stops. The frame E may be swung from the position shown, for example, in
3 come in
Figure 4, to the raised position shown in Figure 3 where the stops >
contact with the stops. The raising operation is rendered easy by the springs E¹
which tend to counterbalance the swinging fiame Jominated in bearings at the
upper for ward ends of the side-fiames is a shaft E', which beyond its bearing on
the side B is provided with a handle E Pivoted upon the shaft E are T-shaped
arms between the head portions of which extends a rod affording a handle
The T-shaped arms E' which operate as fastenings for the swinging platen-
frame fit at their stem-portions into vertical recesses (see Fig 11) in the
ends of the side-bars E, and then enlarged head-portions extend above the said
ends The shaft E is slightly reduced in diameter at the end-poitions which pass
through the bearings, as shown in Figure 38, and the encumferential surface of
the body-portion of the shaft 15 eccentric with relation to the bearing ends, giving
to the shaft the character of a cam. Turning of the handle E in one duection
causes the arms E' to be nised in the recesses, to disengage then heads from
the upper surfaces of the side bais E', whereby by grasping the 1od o handle
the arm E may be swung for ward against stops on the side-frames, to release the
platen frame and permit the latter to be grasped at its handle and raised to the
position shown in Figures 5 and 11, to give free access to the oscillating bed of
the press hereineftei described. When the platen frame is swung down to its
horizontal position against the surfaces r, it may be firmly locked in place by
swinging the aims E' into the recesses and mining the Shaft E, by means of
the handle E, to dian the aims in the downward duection and cause then heads
to engage and clamp the side hais E to the surfaces ».
The plate or body-portion E' of the swinging platen-fiame has a vertical central
opening for a platen-sustaining bolt q thi ealed at opposite ends (see Fig. 7), and
four vertical threaded openings, equidistant from the center, for platen-adjusting
set-screws provided at the upper ends with hand-wheels 2, and reduced in
diameter at their lower ends. The plate, affording the platen of the press, has
a central threaded socket 3 on its upper side which engages the lower threaded
end of the sustaining bolt 7. On the upper threaded end of the bolt is a nut q
which bears upon the upper surface of the plate E, and may be tuned to nise
or lower the platen bodily. The set-screws q extend at the reduced ends into
sockets q in the upper side of the platen (see Figure 6) and are provided above
the plate E' with jamb-nuts q. By turning the nut and hand-wheels q² the

page_text: pinten may be quickly adjusted over its entire smface with great exactuess to
regulate the impression Poted to the platen at opposite ends are swinging
stirrups q for clamping a tympan F¹ in place
G is the oscillating jaw or bed of the press having backward extending arms G
pivoted at their ends to the shaft B³. Fastened against the lateral edges of the
bed are side-bais G² held adjustably in place by means of screws p (see Figure 11)
passing through vertically elongated sockets p in the side-bars. The side-bars
afford tracks for the form inking-rollers, hereinafter described, to un upon, and
may be raised and lowered with relation to the surface of the bed, a distance
limited by the length of the slots p', to regulate the pressure of the inking-1ollors
against the form.
Cast upon the upper su face of the base-plate B is a longitudinally extending
rib B. Haie stationary toggle-guides, each comprising a casting fitting at its
underside, near the front, over the ib 13, to which it is secured by a bolt n passing
through a lug' on the casting, and termuating at the tear of its base in a plate
which fits upon the base-plate B, and is firmly secured thereto by a bolt n
Each guide II is preferably of the U-shape shown, piesenting a lower inclined
bearing suface o plane II' terminating at its upper end in a bearing surface or
plane H extending at an angle thereto, and preferably parallel with the plane of the
platen F, that being the plane at which the impression is made, and having an
upper overhanging arm or retainer II, presenting an inclined under surface or
plane H, parallel with the plane H' Cast integral with the side-frame B is a
sleeve-bearing B for a short houzontal shaft K At the outer side of the frame
the shaft is provided with a gear-wheel K which engages and is duven by the
pinion t
Ou the opposite end of the shaft is a disk-wheel K². I is a plunger of
toggle operating bat pivotally secured at one end upon the side of the disk K2,
and pivotally connected at its opposite end to a shaft I, nidway of the length of
the latter The shaft extends through the guides II and in the latter callies
1ollers I, of a diameter but slightly less than the distance between the inclined
planes H
On the underside of the bed-plate G, are end lugs p² and
intermediate lugs p all in line with each other and affording end and intermediate
bearings for a shaft 13. 14 is a toggle-bar or leaf comprising a frame having
upward projecting beatings arms in which engage pivotally with the shaft 1³
fitting between the respective bearings p² p³, arms mat opposite ends engaging
the ends of the shaft I, and intermediate bearings m² which engage the shalt I'
at opposite sides of the plunger or toggle operating bai I
The frame I¹ straddles
and overrides the aims H³ of the toggle-guides, the rollers 1 being confined in the
guides and against lateral play by the respective bearings m² m² In the 1otation
of the shaft K and disk K³, the plunger-bai is 1cciprocated In the forward
movement of the bar it draws the 1ollers 1 up the inclined plane H' to the
horizontal plane II, thereby extending the toggle-leaf and raising the type-bed
in the direction of the platen The parts are preferably so constructed with
elation to each other that the rollers 12 reach the plane II a very little m
advance of the angle of the greatest extension of the leaf I, and just as the form
starts to impress against the platen. In the final forward movement of the
plunger the rollers rock upon the plane H until the leaf I reaches the angle of
greatest extension. This change in duection of the olleis unmediately increases
the leverage of the parts and consequently tho power exerted against the bed, at
the time of making the impression, when the greatest power is icquired
Thus it
will be understood that in the final movement, during which the impression is
made, the toggle-leaf and 1ollers operate as a toggle puie and simple, the rollers at
that time being stationary (in the sense of not traveling) upon the verge of the
plane H and 1ock thereon in the untune of a lower toggle-leaf. While the own
weight and the weight of the bed would tend to keep the rollers in contact with
the plane H, in the backward movement of the bai 1, thero is danger, when
running at high speed, that the rollers in leaving the plane II for the inclined
plane, will jump, however slightly, thereby Jaining the parts and rendering the

page_text: operation noisy. The arms 13 hold the rollers to the surfaces whereby
jumping is prevented and the operation rendered practically noiseless. Fo
convenience of construction and for purpose of durability, the plane 12 is afforded
by short plates or shoes II bolted in place. The shoes inay be of haidened steel
the better to withstand wear, and in case of wear at then angles they may be
removed and replaced with new shoes
On the outer sides of the arms G' ate pivotal bearings for the upper ends of the
rods G³ which reciprocate through guide openings in the lugs on the base-
plate B. Sounding the rods G and confined between the collars thereon and
the lugs are springs G which thus operate to counter balance the bed to assist
the rise and resist lowering thereof The mechanism described for oscillating the
type-bed, on account of the comparative case and smoothness with which it
operates, permits the press to be iun at a high rate of speed without noise ol

Secured across the front of the machine, in the position shown, is
fountain L which may be of common construction On the end-portion of the
shaft K just beyond the rear wheel K is a cam K³ of the form most plainly
indicated by full and dotted lines in Figure 4. Beyond tho said cam, ou the
extreme end of the shaft K, is a wheel K, provided with a peupheral cam-
groove, see Figures 1, 2 and 3 Extending longitudinally across the ear
edge of the fountain is a fountain-1oller L', the shaft L of which extends
beyond the side-frame B³. Mounted loosely upon the shaft L, just beyond the
side-frame B³, 18 a disk L³ provided in its periphery with a series of notches k,
on one side, and at its opposite side with a laterally extending segmental
shoulder k, see Figure 12. Adjacent to the disk L³ and fixed to the shaft is
a ratchet wheel Lover which the shoulder extends. Loosely mounted upon
the end of the shaft L is a sleeve L³ provided with a handle L and an aun L'
extending at an angle to the handle. The handle caruies a pivotal pawl ² to
ide upon the shoulder and engage the teeth of the ratchet L. L is a lod
(see Figure 4) pivotally connected at its upper end to the free end of the aim L'.
At its lower end the iod L is formed with a longitudinal loop which receives
a pin or bolt on the side of the wheel K Fastened at its upper end to
pin on the rod, and at its lower end to a loop ou the pin or bolt ', is a
spung k
In the rotation of the shaft K, and consequent rotation of the
wheel K', the pin engages the upper end of the loop 3 and 1aises the 1od L*
longitudinally to turn the arm with the sleeve L and handle L upou the
abaft L In this movement of the handle L the pawl engages the intchet L'
and turns it, the shait L and fountain-roller L' It is desiable in practice to
regulate the distance of turning of the fountain roller L' with each operation in
order to regulate the quantity ot inh taken by the roller from the fountain and
fed to the next 1oller, as hereinafter described. For this purpose we provide a
spring-catch T, which is fastened at its lower end to the fianie of the fountain L
and 18 adapted, at its upper end, to engage any one of the notches in the disk L³
In the forward movement of the handle L the pawludes upon the shoulder /
to the end of the latter, whence it drops to and engages a tooth of the ratchet
Thus the distance of rotation of the shaft L2 and fountain-1oller may be regulated
by turning the disk to cause the forward end of the shoulder to approach on
recede from the point marking the forward limit of averse of the pawl By tun mug
the disk L³ from the position shown in Figure 12 toward the lelt the degree of rotation
of the shaft L, with each operation, will be reduced, and by turning, the disk to
move the shoulder to the night the degree of rotation given to the shaft and fountai
roller will be increased When the disk L is adjusted to the position desired it is
held in adjusted position by engagement of the spung-catch L" with the notch &
with which it registers. When the 1od L is thrust upward by the movement of
the pin, as described, it moves against the resistance of the sping, and when
the pin releases the end of the loop the sping ietiacts the rod Is and turns the
sleeve L, handle L and pawl 2 to then initial positions, where the pawl

stationary
Jounaled upon the outer side of the side-frame B³, in the position shown in
Figure 4, is an idle pinion M, the teeth of which engage the gear-wheel K'
Extending at opposite ends though bearings in the side-frames B B is a
rotary longitudinally reciprocating shaft M canying between its bearings an
inking-oller or dium M2, which supplies ink to the form-roller. On the shaft Mt
Just beyond the side-frame B is a pinion M³ engaging the idle pinion M, and
next to the pinion M³ on the end of the shaft M is a wheel M having a
peripheral groove M³ a curved oscillating bar pivotally connected at its lower
end to a lug B on the side-frame B. Between its cuds the bar M is pro-
vided with a laterally extending pin carrying a toller which extends into
and engages the cam-groove 7 of the wheel K+
At its upper end the
bar M is provided with a pin carrying a roller which extends into and
engages the peripheral groove of the wheel M* In the rotation of tho
shaft K the shaft M' is notated by the gears K₁ M M³, and is reciprocated in its
bearings to a limited extent by the engagement of the bar M with the grooved
wheel M, the bar being oscillated by the cam-wheel K*
Jounaled at opposite ends in bearings in the side fiames B B is a rock-
shaft L, provided just within its bearings with short tadially extending arins L"
which are fixed to the shaft. At then ee ends the aims Lafford beamngs for
the opposite ends of a shaft carrying a conductor o mk-transferring roller L
Beyond the side 13 is a rocket-aim L fixed at its upper end to the shaft L" and
pivotally connected at its lower end to the lower end of a 1od L". At its opposite
o upper end the rod L" extends though and reciprocates in a guide afforded by
a lug or bracket B on the side-frame B³, see Figme 4 Between its ends the
aun L is provided with a laterally extending pin 1,18 carrying a roller L16 wluch
beans against the cam K³ The can K is provided with a reduced surface K³
concentric with the shalt K and an enlarged surface K also concentue with the
said shaft. On the 1od L" is a sping L confined between the guide B and a
colla upon the rod, the sping operating normally to press the arm L13 at its free
end in the downward duection and cause the wheel Lis to beat against the surface
of the cam K³ In the rotation of the cam the engagement of the roller L with
the eulanged surface K causes the arm to lock and rock the shaft L10 and arms L",
whereby the mk-ta ansfering tolle L is swung into engagement with the fountain-
1oller 1, and when the roller L1 bears against the reduced cam-surface K³, the
arm Lock-shaft L and aims L" ale rocked to carry the ink-transferring
roller L into engagement with the inking-dium M²
From the foregoing description it will be understood that in the operation of the
machine ink is taken from the fountam L by the fountain-1oller L' and transferred
from the said roller by means of the vibrating rolle L to the rotary_reciprocating
drum M. At opposite ends of the bed Gare form-1oller guides N. Each guide N
16 preferably of the forin shown most clearly in Figure 9, having the rounded end-
portion at which it is pivoted to the side of the bed, an edge affording
an outer track-ial, a hip or projection affording an inner tack-rail
and a bifurcated end presenting a socket . Loose upon the shaft Mi
beyond opposite ends of the dium M2 ate squared blocks having recesses
nt opposite edges in which the bifurcated ends of the guides N slide, as indicated
Ju the oscillation of the bed G the guides N oscillate at one end with the bed, and
slide back and forth at then opposite ends upon the blocks 5, which oscillate upon
the shaft M' On the shafts of the rollers P are collars at which the rollers
travel upon the tracks GN. The collars on the forward roller Pare wide to
present wide trends which will travel upon the rails to the rails and then upon
the rails while the collais on the tear roller Paie aanged to travel in
planes beyond the plane of the rails > The parts are so constructed and timed
in their inoveinents with iclation to each other, that the rails register exactly
with the circumferential surfaces of the dium M when the forward roller P, in its

page_text: movement in either duection, is at the forward ends of the raile, thus it will move
from the rails to the drum M and return to the rails without jai
The rails,
in the same way, register with the drum M12 when the enr 1oller P leaves one for
the other Thus the rollers P will at all times travel upon smooth tracks without
Jaring If thee ollers P are employed, additional track-1ails should be provided
to register with the drum M at the proper moments Beyond then collars the
shafts of the rollers P are jou naled in pivotal heads on the upper cuds of the
longitudinally movable rods P' carried by swinging atms P. Each arin P³ 15
pivoted at its lower end to a beaung-pin or bolt 18 on the adjacent side-frame of
the machine. The roller-carrying rods P extend through guides in the ends of
the aims P2 and are surrounded by confined springs, in the usual manner, which
tend to diaw the rollers in the direction of the pivots B and thus hold the collais
or 1oller-ends to the tracks on which they un On the forward side of each
arm is an extension or finger 13. Rigidly secured at their upper ends to the
lugs on the bed are downward extending aims P4 provided at then lower ends
with longitudinally extending loops, see Figure 5 Pivotally connected at one
end to the loops are links P which at then opposite ends are provided with
loops at which they are pivotally connected to the free end-poitions of the
fingers P In the movement of the type-bed in the downward duection the
arms are sung downward and backward to draw the links P in the backward
direction and swing the aims P2 in the backward direction on the pivots B³, causing
the olleis P to travel from the inking-din over the tracks N G² across the form
In the movement of the type-bed in the upward duection the aims late swung
at then lower ends in the forvard upward duection, thi usting the links 1'5 for ward
and swinging the aims P2 in the forward direction, whereby the olleis move along
the guides G N to the inking-din M² The rear ends of the links Pt may be
pivotally secured at any location in the loups, and may be secured at then forward
ends to the fingers Pª at any location in the loops Thus the throw of the
aims and the distance of traverse of the rollers P may be regulated. For
example, if the form to be puuted is smallet than the capacity of the ty pe-bed it
may be locked down neat the forward edge of the bed and the links P may be
adjusted at the opposite ends to cause the tollers P to navel from the inking-drum
to the end of the form and no further
In the oscillation of the type-bed the rollers are guided by their tracks, afforded
by the rails G and guides N, substantially man are ot which the pivots Bs are
the center
In other words, the tellers travel along a smooth track without turning
any angles, and in a path so nearly the are of a cncle that there is very little
expansion and contraction of the springs in the aims P
In oscillating presses the speed of the press is limited by the speed at which the
form inhing tollers may safely travel, and as in all other presses the rollers have
to travel around angles the speed at which such presses may be run is necessarily
slow, for the reason that when tunning over angles the rollers will jump if traveling
faster than a certain speed and will soon injure the parts by Janing
In the
present construction the speed at which the rollers may be caused to travel 15
practically unlimited, for the reason that they turn no angles and are held at all times
securely to the tracks. and, owing to this feature, the present press may be un
to a speed approximating 5000 impressions au houi as against about 2500 impies-
sions, which latter is considered a very high speed for other oscillating presses
Besides, the meleased speed thus attained, the present construction causes the
olleis to be practically noiseless in operation, a feature of advantage which other
oscillating presses do not possess
By reciprocating the inking-diam M³ a perfectly even distibution of the ink is
obtained, as it evolve and slides in contact with the uk-transferung roller L'
and the form-mking rollers P.
The inking-diam M2, which is provided upon the press, is formed preferably in
separable sections M³ which may be slid longitudinally along the shaft M' and
bunched together to afford a continuous inking dium, or separated, as indicated in

page_text: Figures 8 or 10, when it is desued to print in different colors. As will be seen by
referring to Figues 8 and 10 the sections M³ are of different lengths to permit
separation of the sections at different parts with reference to the form upon the
type-bed If it is desired to print in three colois, for example, the sections M³
may be adjusted upon the shaft, as indicated in Figure 8, and two sliding
partitions L may be placed in the ink fountain in the position shown, to divide
the different colored inks from each other. As sliding partitions I have been
employed in connection with fountains L before, it is not thought necessary to
illustrate them in detail The different colored inks taken by the transfering-
roller L will be separated when received from the fountain-roller, and the spaces
on lines of separation will register, as the transferring-roller comes into contact
with the dium, with the spaces between sections M³, which spaces, in practice, may
approximate one-half an inch in length. The degree of reciprocation given to the
dium by the cam K' and arm M also approximate one-half an inch, or one-quarter
of an inch in opposite duections from the cential line of the color separating spaces
on the transferring-rollet, so that in the reciprocation the inks on the transfering
roller are not caused to intermix at the edges When the form ollers P come
into contact with the drum the different colored inks are transferred thereto and
spread by the reciprocating drum in a manner to touch without overlapping. Thus
on the form-rollers the different colored inks will be divided by well defined lines.
The improved machine is adapted to print upon a web %, unwound from a
roll through the operation of intermittent feed-mechanism R, whence it passes
to cutting mechanism S which severs the web into sheets.

Secured upon the side-frame B² of the machine are arms T T, toward the front
and back of the machine, extending laterally in an upwardly curved direction.
At their fico ends the arms T are bifurcated, see Figure 14, to afford sockets h
across which extend short shafts carrying overlapping wheels affording anti-
friction bearings for the opposite end-poitions of a horizontal support or shaft h
On the outer side of the aims T are upward extending socket-pieces through
which the opposite ends of the shaft ³ extend, and upon the shaft, between the
socket-pieces and adjacent bearings h, are collars which fit betweon the said
socket-p
-pieces and beaungs to prevent longitudinal play of the shaft. The sockets
of the socket-pieces prevent lateral play of the shaft The bearings for the
shaft permit the latter to be rotated without apparent friction and to be readily
lifted out of o serted into place when desued. The means for securing &
roll Z upon the shaft comprises blocks or collars which may be slipped upon
the shaft and fastened in adjusted position by means of thumb-screws h°, and
clamps which may be in the form of cone-shaped blocks having central
longitudinal openings 8, which at the small ends of the clamps fit loosely around
the shaft and are enlarged at the laige ends of the clamps to fit loosely over the
blocks Extending through the enlarged end-portions of the clamps hare
thumb-screws 16 adapted to engage sockets 7 m the blocks A, by means of which
the clamps may be secured to the blocks and centered thereon with relation to
the center of gravity of the roll. In placing a toll Z upon the shaft the clamps
and one of the blocks are removed, the clamps are slipped into the ends of the
roll and then slipped over the shaft. The blocks are then adjusted upon the
shaft with the clamps and roll and fastened in position between the aims T in
proper relation to the form upon the press. The blocks are then tightened upon
the shaft and the clamps adjusted by means of the thumb-screw to cause the
center of gravity of the roll to coincide or register with the center of rotation of
the shaft From the roll the web passes down beneath an unwinder, consisting
of an aim o 1oller on the lower end of a downward extending 1od or lever h".
At its upper end the rod is fastened upon a sleeve which loosely surrounds a
pin on the ear edge of the base-plate B Surrounding the pm and
fastened at opposite ends, respectively, to an adjustable collar, ou the pin 1,
and a sleeve is a sping which tends normally to turn the sleeve upon the
pin and press the rod at its fice end, and the roller 20, in the downward
I

page_text: direction. The collar may be turned and adjusted upon the pin ¹³ to increase
or diminish the tension of the spring. The roller h¹ extends in a plane parallel
with the shaft h³.
The intermittent feed for the web, when moving the latter forward between
impressions, starts with a jerk upon the web which, unless means are provided to
prevent it, will have a tendency to tear the web before starting the unwinding of
the roll. In the improved construction the unwinder 40 has the effect of producing
what may be termed a constant slack between the roll Z and piess, and in the
initial tug produced upon the web by the feed it yields in the upwaid ducction
and excits in its rise a constantly increasing resistance owing to its sping 14,
whereby the force excited to turn the roll Z becomes a slow pull instead of a
quick jerk, and by thus decreasing the strain upon the web prevents tearing of
the latter. While an impression is being made the stiain exerted by the
unwinder causes the roll to revolve and pay out the web, the unwinder
descending to its initial position. In practice, in a short time, the impulse given
to the roll causes the latter to evolve at the speed of the feed and there will
consequently be but a slight rise and fall of the unwindci. The construction
Involving the anti-fuction bearings, means for finding the center of gravity of
the roll and the yielding unwinder are important features of the invention. When,
owing to heavier or lighter paper it is desired to increase or reduce the resistance
of the unwinder, this may be done by adjusting the collar 15 upon the pin to

Fastened at opposite ends in the arms T, in the position shown, is a rod or
shaft 9. and upon the aims between the said rod g and side of the machine are
upward extensions affording fingers T¹ T At the junctions of the fingers T¹ T
are bearings for a Loss-10d g'. The fingers Tafford beatings for the opposite
end-portions of a rocking crauk-shaft o, and the fingers T afford bearings for a
cross-ind g10 On the end of the shaft, at the forward side of the machine, 15 a
handle, see Figures 1 and 13. T3 is an adjustable curved web-guide comprising
two shiding end guide-pieces y' y' and an intermediate sliding guide-piece 4°. The
guide-pieces are provided on then under sides near their lower ends with socket
projections g, see Figure 11, which fit over the rod g, and at then centers they
rest at beamng surfaces upon the rod g¹. Secuied to one of the end guide
pieces is a stup g which rests and slides in recesses g in the upper ends of the
other guide-pieces, see Figures 5, 6 and 11 Ou the outer edges of the guide-
jueces are flanges g affording edge guides for the web Tis an adjustable
brake or tensioning mechanism for the web It comprises a lever g pivoted at
one end-poition upon the rod 90 aud can ymg at its opposite end a stup g¹³, which
is preferably padded on its under face and extends parallel with the strip g8"
against the upper surface of which it is adapted to beat. Above the rod go the
lever is provided with two lugs g" affording between them a socket into which
extend thumb-sciens g from opposite sides Pivoted upon the 1od adjacent
to the level g² is a bell-crank lever g which at one end extends into the socket
between the lugs g, and at its opposite end is formed with a loop g" through
which passes the shaft g2. The thumb-screw 15 bears against opposite sides of
the end of the lever q which extends between the lug g, whereby the levers gla
and are practically one in operation. The padded web-engaging surface of
the part may be pressed against the web at the strip g³, or 1nised out of contact
therewith, by swinging the lever g2 g, forming the tensioner T upon the pivot glo,
this being accomplished by turning of the cam-shalt g2 by means of the handle g³.
By tumug the bandle g in one direction it tuins the cam-shaft in the downwaid
direction, swinging down the end-poition of the lever, and raising the end-
portion thereof, to disengage the tensioning-bai g from the web, and turning
the handle o in the opposite direction causes the end g of the level to be raised,
and the end thereof to he lowered, to press the tensioning-strip q3 against the
web. The degice of pressure of the tensioning-strip against the web is regulated
by means of the thumb-sciew g, which may be tuned to shift the end of the

change the relative angles of the parts or levers 912 918. The guide-pieces g* y
may be readily slid on then bearings g gl and secured in adjusted position by means
of set-screws g18. In practice they are so adjusted that the flanges g" will be a
distance apart equal to the width of the web aud the guide-piece g midway between
them The web guide T3 terminates at the side B2 in the plane of the undei
su face of the platen The curved guide T' directs the web from the unwinder to
a plane at which it is to pass across the platen of the press, and the main object
of providing the guide in the form shown and described is to cause the web to
extend flatwise and not curl at the edges. Were the web fed in a straight line
to the press it would tend, especially in the case of thin paper, to curl at the.
edges, while in passing over a curved surface, like that affoided by the guide T³,
the tendency of the web to curl is ovci come
The intermittent-feed mechanism R for the web is mounted upon a standard R
having a base-plate R³ which at its opposite end fits upon the rails A' A² of the
base A. The standard is clamped at its base upon the rails A' A' by means of a
clamping-bai R3 which is tightened to the plate R, against the undersides of the
raile, by a bolt K. The upper end of the standard R is formed into a frame
compusing a lower part or base-bai R, side-bai R, and pivotal top-bar R.
Secured upon the forward face and center of the arm R' is a downward extending
yoke or stip-fiame R, which at its free ends affords bearings for a horizontal
shaft provided between its bearings with a feed-roller f¹ and beyond one of its
bearings with a pinion At the forward end of the base-bar R is an upward
extending aim Ŕ Journaled in a bearing R, on the base-bai R, and in a
beaning R, upon the arm R³, is a horizontal shaft f³ provided at one end with a
pinion, engaging the pinion 1, and provided between its beanings with web-
leeding disks or wheels ff³, which bear normally against the roller f.
On the counter-shaft D is an eccentric D' having a rotary center D² surrounded
by a ring D. Pivotally connected at its lower end to ears e on the ring D³ 18 a
pitman D'
Crossing the middle of the center D2 is a cui ved recess of opening e
at which the said center fits over the shaft D. The opening el descubes the arc
of a cucle of which the bolt et is the center. On the shaft D is a sleeve e provided
with a lug or aim et pivoted upon the bolt e, and also upon the sleeve e 18 &
lug on aime provided with a bolt es which passes through a recess or opening e
in the center D' describing an arc of a cicle of which the bolt is also the
center. The center D may be adjusted to any position within the limits of its
opening e on the shaft D and may be firmly secmed in adjusted position by
tightening the bolts ee. Thus the eccentric movement of the center Ds and the
consequent eccentric movement of the ung D3 may be regulated by changing the
relative positions of the center and shaft D It will be understood that the center D'
rotates in the ring D³ and gives to the pitman D₁ a reciprocal motion in the
vertical plane. D is a vertically reciprocating tack-bar movable in guides ƒ ƒ on
the forward end of the bar R5 and upper end-portion of the an R, respectively.
The ack-ba s pivotally connected at its lower end by means of a link Do with the
upper end of the pitman D On the shaft is a loose pintou ƒ³, see Figures 33
and 36, caying a radially extending atin, provided at its free end with a
laterally extending finger f. Adjacent to the aim f, upon the shaft is an arm "
somewhat shorter than the arm 1". The arm is secured to the pimon by
means of a screw f, and the arm f" is provided internally with a friction-block
which is held yieldingly against the shaft by a set-screw and a confined spring 13,
so that the arm " will, on account of the fnction of the block against the shaft,
move tardily with relation to the at inf Secured to the shaft at the outer end
of the latter is a ratchet-wheel 14. Pivoted at one end on a bolt on the
finger is a pawl pivoted between its ends to a bolt on the free end of
the aim and adapted to engage the ratchet-wheel 4 On the arin f" is a
fingecanying a pin which extends over the pawl.

In the rotation of the shaft D the eccentric is evolved to reciprocate the

page_text: pitman D and through the latter the rack D In the upward movement of the
rack it rotates the pinion fa and arm f, causing the latter to move in the direction
of the aim f", and dip the pawl 1 into engagement with the ratchet-wheel, and
olate the arm on the shaft, and also the ratchet-wheel" to tuin the shaft.
In the downward movement of the rack-ba it 1otates the pinion in the opposito
direction, causing the arm to be withdrawn in the backward duection slightly
away from the aim f, raise the pawl out of engagement with the ratchet, against
the stop, aud swing the pawl and aim f" to the initial position icady to take
a new gup upou the ratchet-wheel In the return of the parts in the downward
reciprocation of the rack-ban, the shaft remains stationny. To prevent all
danger of the shaft's being 10lated by inertia too far in the forward dicction, or
in the backward direction by fiiction of the block f' upon the shaft, we provide a
wheel on the shaft having a circumferential fiction-surface, and upon the
bar R we provide a leaf-spring ƒ", which at its free end beais against the wheel ₤18,
thus operating as a bake.
Pivotally mounted upon the shaft is a frame consisting of side-bars can the
form of bell-ciauk levers and a cross-bai el connecting the lower aims of the said
side-bais. Journaled at opposite ends in the free ends of the upper arms of the
side-bars c is a shaft 2 cariying a guide-roller ca for the web The circumferential
surface of the roller c³ is roughened or sanded Journaled at opposite ends in the
upper arms of the side-bais is a shaft c, and extending between the same parts
and parallel with the shaft c is a rod c³. Pivoted upon the rod c, near the ends
of the latter, are adjustable swinging aims, which at their fice ends aflord
bearings for the opposite ends of a shaft . On the arms are lugs having
openings to receive adjusting-sciens c which extend through the said openings
into internally threaded swinging socket-pieces el on the outer ends of the shaft c*.
The shaft extends above and parallel with the shaft c', and the distance
between the said shafts may be varied by turning the adjusting-sciews c. The
shafts may be provided, as shown in Figure 29, with revolving co-opciating
cutting-disks coi with evolving co-operating perforator-wheels The
cutting-disks have beveled cucumferential cutting-edges, and when mounted
upon the shafts are adjusted to overlap and bear against each other, as indicated
in Figures 29 and 31. The perforating-wheels are disks provided with
circumferential flauges at one side. The flange of the disk c is provided with
radial cutting-teeth c, see Figure 32, which fit and work in sockets c in the
disk c. The teeth el produce perforations in the web, as the latter travels between
them, by cutting pieces out of the web, the pieces dropping through the openings
or sockets c¹6. At the center of the cross-bar c' is a thumb-screw c which beats
against the surface of the standard R. The wheel and cutting or perforating
disks may be raised or lowered to a limited extent with relation to the feed-10llers
by taming the screw c¹6.
The aim R is pivoted at 24 to the upper end of the part Re, whereby it may be
swung in the vertical plane. Pivoted upon the upper end of the aim R³ is a
Swinging yoke-shaped latch R adapted to swing over the tice end of the am R7
and engage the latter. In the upper end of the yoke R is a thumb-screw f' and
on the upper surface of the arm R is a finger-spring / To secure the aim R
down, the latch R is swung over the end thereof and over the free end of the
spring, and the thumb-sciew 22 is screwed down against the spring / 23, whereby
the aim is fastened down yieldingly at its free end, and thus causes the web-
feeding roller to bear yieldingly upon the feeding-disks f. When it is desired
to adjust the dishs fb the thumb-sciew may be loosened and the latch swung
out of engagement with the arm, leaving the latter free to be raised on its
pivot ₤24
Bolted upon the standard R' is an arm or plate S¹ having a T-head S² presenting
a straight horizontal upper surface d. Pivoted at one end to the rear end of the
head is a swinging-arm S. On the counter-shaft D is an eccentile S', coire-
sponding in construction with the eccentric D¹ described. Pivotally connected at

page_text: its lower end between lugs on the ing of the eccentric S is a rod S theaded at its
upper end
On the threaded part of the 1od S and adjustable theicon along the
threads is a link S which is removably pivoted by means of a bolt S to the fiee
end of the swinging arm S³. Removably fastened upon the face of the head S³ is a
cutting-knife S8 and on the aim S³ is a cutting-knife S, the knives affording
co-operating shearing-blades for severing sheets from the web as it passes
between then. Fastened over the surface d is a strip of paper on the like d' sauded
or roughened on its upper surface Above the roughened surface is a plate S¹º
which may be mounted at opposite ends upon set-screws d which rest in sockets (³
toward opposite ends of the sin face d. The under surface d' of the plate extends
parallel with the sanded surface and the two surfaces afford between them a
guide-passage for the web to the sheang-kuives, and this guide-passage may be
enlarged o educed according to the thickness of the web material by ineaus
of the set-screws d. The plate So when inserted in place is slipped at one end-
under a spring d', Figures 3 and 21, which operates to hold the plate in place.
Fastened at its upper end to the plate S' is a plate b resting at its lower end
against the standard R' and provided near said end with a threaded socket b'.
Wis the delivery of the press, comprising a platform 2 hinged at one edge to the
upper edge of a T-shaped frame Wi. The stem-portion of the frame Wis-pro-
vided with a vertical slot 63, which receives the shank of a thumb-screw 6 which
engages the socket 6 in the plate b On the under side of the platform is a
longitudinally slotted strip 60. Pivoted at one end to an ear on the frame W'
is a swinging arm 67 provided at its fice end with a screw 68 which passes through
the elongated opening in the strip b³ The frame W may be raised or lowered by
loosening the thumb-screw 6 and may be fastened in adjusted position by tightening
the sand thumb-sciew The platform & may also be taised and lowered upon its
hinges by loosening the sciew &, so that it can be slid in the elongated opening,
and the screw is tightened again when the platform has been adjusted to the prope
angle lo the upper face of the platform is a T-socket 6. Sliding upon the
platform² is a stop-plate a fastened at its lower edge portion to a block a¹ having
a base-portion a Fitting at its head in the T-socket is a bolt a³ which extends
at its shank-portion through the base a above which it carries a thumb-nut at
The stop a extends at a right angle to the plattor in 63, and on loosening the nut at
at may be slid along the latter and fastened in adjusted position by tightening the
said nut.

To place a form in the press the platen frame E is disengaged from its fastening
at the forward end by turning the handle E, as described, and swinging the
frame E to the stops r The platen-frame is swung upon its pivot B until its
stops engage the stops, this operation being rendered easy by the counter-
balancing springs E. When the platen flame is thus swung out of the way, fiee
access may be had to the bed of the piess, aud the chase V, containing the form to
be printed, is placed against chase engaging stops at the forward end of the bed,
and fastened down by means of a pivotal latch oi clanıp vl. The stops fit snugly
over the rounded or beveled forward edge of the chase, and the clamp is pivoted
upon a bolt 3, which extends through a slotted bracket at the center of the lear
edge of the bed. The clamp is swung upon its pivot to overlap and engage the
rear edge of the chase and is fastened down by tightening the bolt to clamp the
chase in place. The stops and clamp form a particularly desuable fastening-means,
which may be quickly and easily adjusted, and hold the chase firmly to the bed.
The platen-frame is then lowered and locked down, as described, and the platen
adjusted it necessary by means of the nut q and screws q to give the proper
impression. If one form only is to be printed which substantially fills the chase
from front to back, and the printing is to be done in one color, the sections M³ of the
inking-dium o olle M³ are adjusted close together to afford a continuous cucum-
ferential surface, and the form-tollers P are adjusted, by adjusting the links Ps, as
described, to travel from the dium M entirely across the bed If a form is to be
printed which extends materially short of the distance from the front to the
L 1
.

page_text: back ner edge of the chase, the rollers P may be adjusted, by means of the
links P, to travel from the drum M³ just far enough along the chase to mk
the form. For the reason, as before stated, that the speed of the operation of the
press is limited by the speed of the form-inking rollers, by reducing the distance
which the said rollers are to travel, the speed of the press may be mcreased when
small forms are to be printed. If two or more forms are locked side by side in the
chase and are to be punted in two or more colors, the sections M' of the drum are
separated, as required, and partitions L are placed in the fountain L to divide
the colors from each other. The roll of paper is then mounted upon the shaft h²,
as descubed, and the web is unrolled and passed therefrom under the unwinder 10
up over the curved guide T3; the padded tensioning-stip 918 is raised by turning
the handle g, as described, and the web te passed from between the tensioning-strip
aid the plate g, between the platen and bed of the press over the roughened
roller 0³. The arm R is unlocked and raised, as described, and the web 15 passed
between the feed roller and the feed-disk and through the opening betwcen
the plate S and roughened platfound to the sheating knives. If the form in the
press 18 to punt one color the web-feed mechanism must be adjusted to feed the
web once with cach impression a distance equal to the distance across the form
and margins to be left upon the sheets, and the web-cutting mechanism must be
adjusted to cut across the web once with each impression. If there are two forms
upon the press printing in different colors, and the printing is to be in two colors,
then the feed must operate once with each impression and feed the web a distance
equal to the distance between the forms. If the press is to print several forms at
once which are to be divided into separate sheets by the cutting mechanism S, then
the web-feed must be operated to advance the web two or more times with each
impression, as required, and the cutting mechanism must cut the same number of
times. The distance of feed of the web is regulated by the adjustment of the
eccentric D. To diminish the throw of the eccentric its center is adjusted upon
the shaft D closer to the center in the opening e¹ as described, and to increase the
throw of the eccentric it is adjusted in the opposite direction in the said opening.
The throw of the eccentric regulates the distance of the rise of the rack bai D' and
consequently the degree of rotation given to the feed-roller and feed-disks.
Thus the feed-1ollers may be adjusted to advance the web to any extent with each
operation. The feed and cutting mechanisms in the machine shown, operate once
with each evolution of the counter-shaft D. The pinions ss 52 on the counter-
shaft are of such sizes with relation to the pinions t³ on the drive-shaft and
gear-mechanism between the dive-shaft and the oscillating bed, that when the
pinious stare coupled into engagement, the counter-shaft will rotate once with
each oscillation of the ty pe-bed, when the pious t's' are coupled into engagement,
the counter-shaft will rotate twice with each oscillation of the bed; and when the
pinions are coupled into engagement, the counter-shaft will rotate three times
with each oscillation of the type-bed. Thus in the press shown, either one, two or
three feeds and cuts may be exerted upon the web, as desired, with each impression.
If it is desued to shit or perforate the web, the cutter-disks c¹, or perforating disks,
are adjusted upou the shafts c' c', as described, whereby the web as it is diawn
across the disks between the shafts is slit or perforated, as the case may be. The
tension-bar a 15 adjusted by means of the thumb-screws g to exert the desned
pressure against the web and hold the latter taut between the strips g and feed-
mechanism In operation the web travels from the press over the roughened
1oller c³, which roller engages the under or printed side of the web. It is found in
practice that roughened or sanded roller c³ does not take off the ink or smudge
the sheet; while a smooth roller would have that objection. The feed-disks f arc
adjusted far enough apart to engage the opposite edges of the web beyond the
printed surface, so that while they engage and guide the web toward its opposite
edges, they do not come into contact with the printed surface The web slides
from the feed-1olls to the cutting knives over the roughened surface whereby, it
1s found, the printed surface of the web is not injured as it would be in sliding

page_text: over a smooth surface at that point. As the sheets are severed from the web they
diop upon the delivery W, the stop a being adjusted at a distance from the knives
which will cause the edge of the severed sheet to fall upon the platform without
sliding upon the sheet next below it.
The platform may be raised and lowered as
described, when desued.
As an example of the work which may be performed by the press, consti ucted
with the gear-mechanism descubed, in the manufacture of tickets, tags, or the like,
six forms may be locked in the chase and printed at one time, the web fed forward
three times to cach impression, the web slit or perforated longitudinally, and the
cutter-knives operated three times to each impression, or the tags tickets, or the
like, may, 10 three impressions, be printed in three colors and cut and split or
perforated. Additional speed altering-gears may be provided, if desired, whereby
the press may be caused to print additional forms and additional colore.
In a known printing-press the web feeder and cutter are geared directly to the
main driving shaft and the press is operated fiom an auxiliary or counter-shaft,
between which and the main shaft are speed-altering gears, substantially like those
herein described In the present machine the coustiuction is reversed, the press
being geared duectly to the drive-shaft and the web-feeder and cutter to the
counter-shaft. The present construction has advantages over that of the other
press referred to in the application and economy of the power as well as in the
matter of speed. In the former press the ink-supplier in the form of an unking-
table is carried by the oscillating bed, while the present construction relieves the
bed of the weight of the ink-supplier, and permits employment of the fountain
and fountain-rollers, as described, which afford a continuous ink-supply. The
ink-fountain L in practice, usually requires frequent adjustment by means of its
thumb-screws, 3, to regulate the flow of ink, and were the fountain carried by the
oscillating bed the adjustment could not be changed without stopping the press,
which would be in practicable. In the present construction all the advantages are
gamed of a continuous ink-supply without adding to the weight of the oscillating
bed. By the statement that the uk-supplier is relatively stationary, is meant that
the oh-supplier does not oscillate with the type-bed. The ink-supplier may have
independent movements, as described in connection with the king-drum which
reciprocates longitudinally to distibute the ink, and rotates on its axis.
In the present construction the swinging form-roller carrying-aims are pivoted
to and supported by the frame of the machine, and are not carited by the oscil-
lating bed-frame, one of the objects being to relieve the bed as much as possible
from the weight of the parts not necessarily canned thereby, and thus by making
the bed as light as possible, consistent with necessary strength, the power required
to operate the press is reduced approximately to the minimum.
The improved toggle-mechanism descubed may be employed to advantage in
other presses in which the bed and platen are mounted upon the opposite members
of relatively opening and closing Jaws, as in the present construction, and whether
the bed or platen, or both, ale oscillated into and out of the plane at which the
impression is made.
To cause the toggle-mechanism to operate as quickly and easily as possible and
exert comparatively great power at the moment of impression, it is preferred to
provide a straight inclined guide-sun face H³, and a guide-surface II*, exactly
parallel with the plaue at which the impression is made, which the rollers just
reach and rock upon in the final extension of the toggle-bar. Thus while the
impression is being made, the rollers have the character of a lower pivotal toggle-
leaf fulci umed upon the surface H2. Though this is the preferred construction,
the guide-surface II' may be 1ounded instead of straight and inclined to extend
obliquely, to the plane of impression, in the are of a cncle, or otherwise, if desired.
As the rollers may merely touch and rock upon the surface II, the latter may be
of merely appreciable area, and, as in the case of a rounded guide-surface II', may
be simply the nearest approach in a rounded plane, or are of a circle, to the plane
at which the impression is made.
