Improvements in and relating to Printing Presses.
We, CHARLES GRANT HARRIS, Inventor, residing at No. 4 Park Avenue, Niles, and
JOHN FRANKLIN MCNUTT, Inventor, residing at No. 17 West Prospect Street,
Warren, in the County of Trumbull, State of Ohio, United States of America,
do hereby declare the nature of our invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
This invention contemplates certain new and useful improvements in printing
presses, and although it has special reference to, and will be mainly described in
connection with, the printing of cards, or envelopes, yet it is not restricted in this
particular, since many features of the invention are applicable to various forms or
kinds of presses.
One of the many objects of this invention is to provide improved means for clamping
or binding type-forms or plates on the type-carrying cylinder.
A further object is to so mount the impression cylinder that the position thereof
can be readily and easily adjusted.
""
A further object is to provide a simple tripping-device for engaging the cards or
envelopes as they are fed to the press, so that in the event of any irregularity or
interruption in the feed said device will trip "stop" or "throw-off" mechanism, or
both, causing the press to cease operation and the impression-cylinder to be lowered.
A further object is to provide improved "stop" and "throw-off" mechanism.
A further object is to provide improved means for operating the ink-distributing roll.
A further object is to so mount the stops on the impression-cylinder that they will
aid in discharging the cards or the like therefrom.
A further object is to provide improved guides for directing the discharge of the
cards, or the like, those improperly printed being deposited in a compartment separate
from those properly printed.
A further object is to provide an improved trough or receptacle for the cards, or the
like, as they are discharged from the press.
A further object is to provide an improved feeder for feeding one card or envelope
at a time from the bottom of a pile or stack of cards or envelopes.
And a further object is to provide a simple device for controlling the passage of the
cards or envelopes to the press.
The invention will be hereinafter fully set forth and particularly pointed out in
the claims.

Referring to the drawings, A designates the frame of a printing-press; a the type-
carrying cylinder; a¹ the impression-cylinder the journals of said cylinder being
understood to be mounted and geared in the usual manner, save where any
change is hereinafter indicated. The sides of the frame are horizontally divided into
upper and lower sections 1 and 2, the sides of the section 1 being pivotted at their
lower, rear ends by rods 3 supported by ears 4 of section 2. At its front end the
section 1 is held to section 2 by headed bolts 5. The inking apparatus is mounted on
the upper section 1, while cylinders a and a¹ are supported by section 2. Hence
access to the interior of the press can be easily had by raising and moving back
section 1 without disturbing any of the inking rolls.
The type-carrying cylinder is provided with a cutaway portion a² in its periphery
to permit of the insertion of clamps for binding the type-plates. At any point on
this cylinder the type-plates a³ may be rigidly held. In the remainder of the
peripheral surface of this cylinder are two sets of T-grooves a, a, the former being
circumferential and the latter running longitudinally of the cylinder. The type-
plates are held by clamps a adjustable in these grooves. Each clamp consists of an
inner plate a movable in the inner portion of the grooves a, a, and an outer plate a
of greater width, said plates being held together at one end by a binding screw ".
From the underside of the upper plate extends a longitudinal rib at which fits in the
outer portion of the groove, said rib having a portion removed at one end, as at a¹², to
accommodate a short lug a13, of the inner plate a'.
By means of the screw a the two plates can be drawn towards each other so as to
he firmly joined to the cylinder and the projecting ribs and lugs hold said plates as
against lateral movement. The edges of the plate a are beveled as at a14, to accom-
modate and fit snug against the correspondingly beveled edges of the type-plates.
Any necessary number of clamps may be employed for attaching each type-plate to its
cylinder. By means of the two sets of grooves clamps may be applied to all sides of
the type-plates.
The impression-cylinder al has its journals passed through eccentrically located
holes b' of disks 62 from which latter extend hubs or circular portions 6 fitted in holes
in the sides of frame A. The ends of said journals bare extended outward sufficiently
far to accommodate, at one end, a gear-wheel b', and at the other end a cam or
shouldered disk 65 and a curved cam be from each disk 62 extends an arm 7. To the
outer ends of these arms 67 are connected depending rods 68 which are passed through

page_text: upper and lower tubular portions 6º of brackets 610. The lower ends of these rods 68
are threaded to receive nuts 612. By means of these nuts the rods 68 can be adjusted
to control the position or horizontal plane of the impression-cylinder. This is effected
by the raising or the lowering off the outer ends of the arms b'.
If said arms are
raised the cylinder a' is lowered, and if said arms are lowered said cylinder is raised.
This is caused by the journal of the cylinder being mounted eccentrically in the disks b².
The brackets 610 at their lower ends have short extensions 613 which are pivoted
to short arms 64 having their hub-ends fast on shaft C whose ends are mounted in and
extended beyond the sides of the frame. A coil-spring d on this shaft is constantly
under tension when the cylinder a' is in proper position, its office being to effect the
partial rotation of said shaft, and hence the lowering of the impression-cylinder
the instant any break or interruption occurs in the feeding of cards or envelopes to the
press. By means of a handle bar d' attached to one end of this shaft the latter can he
turned as against the spring, winding the latter on said shaft. This shaft is held in
its normal position, with the spring under tension, by a centrally located arm d²
thereon and a trip-block ds, which has a shoulder d with which the outer end of arm of
de contacts. This trip-block is pivoted at d on a lug or projection d of a front portion
d of frame A. A pin de limits the movement of the trip-block in one direction.
The normal position of the latter is perpendicular, but if swing on its pivot so as to
disengage the central arın d², the shaft C will turn under the tension of the spring d.
The means by which this disengagement of the trip-block and the arm of the shaft C
is automatically accomplished the instant there is any break or interruption in the
printing will be described in the proper place. At this point, however, it is in order
to describe the stop-mechanism.
D is a clutch-pulley of any preferred form having a clutch controlling arm e, which,
when its outer end is moved outward or away from the shaft, will cause the pulley
and its shaft to revolve together, and, when moved inward at that end, will disengage
said shaft and pulley. It is mounted on the main operating shaft e', whereon is a
gear-wheel e which neshes with the gear-wheel b' of the impression-cylinder. On
this shaft e' is a sliding collar e3 having a beveled or cone-like end e'. A pin e' of
arm e engages this collar and when in contact with the cylindrical portion of the
latter the shaft and clutch-wheel revolve together, but when said collar is moved so
that the pin engages the beveled or cone end thereof said arm is moved toward the
shaft, disconnecting the clutch-sections, thus allowing the rim or outer portion of the
clutch-wheel to revolve independently of the shaft. A shaft E mounted in a boxing e"
of frame A has at one end a fork e', the inturned ends of which fit in a circumferential
groove e of collar e³.
A coil-spring ex surrounds this shaft within the boxing e" and
its tendency is to hold the clutch out of operation. On the other end of this shaft is
fastened the hub-end e of an arm e¹. When this arm is lowered and the shaft E
turned so as to throw the cylindrical end of the collar beneath the pin of the clutch-
arm, it is so held locked by an arm e pivoted to the boxing e". An arm ela fast on
shaft C is at right angles to this retaining arm e" and is normally held elevated.
But the instant the shaft C is turned, under the tension of its spring, the arm e¹³ flies
downward and striking a shoulder e" of arm e" in rear of the pivot of the latter, said
latter arm will be raised from engagement with a shoulder of the hub e, permitting
the shaft E to partially rotate under the tension of its spring ex, resulting in the
forked end of said shaft moving the sliding collar on the operating shaft, the clutch
being disengaged from said shaft. The reengagement is effected by lowering the
arin e after the handle-bar d' has been lowered to effect the return of the impression-
cylinder to its normal position and the reengagement of the arm d with the trip-block.
In the periphery of the impression-cylinder a is a longitudinal groove or cut-out f,
having opposite inclined walls ff. To the wall is secured a clamping-plate f by
means of screws f'. This clainping-plate is designed to firmly hold one end of the
covering or blanket-sheet w which encompasses the cylinder. It is preferably formed
in three sections to permit of the removal of portions thereof so that a small part of
the covering or blanket-sheet may be cut out and be replaced without disturbing the
remainder. The other end of the covering or blanket sheet is held between two

page_text: continuous clamp-plates f³, fo, which are firmly drawn together by screws f.
Through coincident threaded openings in these clamp-plates are passed adjusting
bolts f, the inner ends of which contact with the inclined wall f. The lower edges
of the clamping-plates are held so as not to be moved bodily away from or
toward the adjacent wall of the cut-out, and hence it will be seen that by
turning these bolts the upper edges of the clamp-plates can be moved
away from the wall f*, thus tightening the covering w. In this way we have provided
simple and efficient means for attaching and stretching the covering of the impression-
cylinder.
F designates a shaft centrally located in the groove or cut-out f and to one edge of
a slightly curved plate fx thereon the stops fº of the impression-cylinder are adjustably
attached. These stops preferably consist of plates f" having shouldered or beveled
ends ƒ and slots through which screws fare passed. A spring fon
this shaft normally holds the stop-plates against the periphery of the cylinder. The
plate substantially covers the groove or cut-out and the stops rest on the
cylinder. On one end of this shaft F is an arm f which engages a shoulder f" on
the adjacent side of frame A so as to partly rock said shaft and permit of the
disengagement of the stops with the card or envelope at the point of discharge, this
movement of the stops aiding in discharging said cards or envelopes from the
cylinder.
G, G, designate two blocks adjustably mounted on a shaft g supported by the sides
of the frame. These blocks are inclined or of wedge-like form, so that their reduced
edges g will be in close proximity to the periphery of the cylinder. The card or
envelope after being printed contacts with these blocks as the stops fare partly
elevated, said blocks effecting the discharge of and guiding said cards in passing
from the press.
H is the feed-table upon which a pile or stack of cards or envelopes is located ready
to be fed to the press, the feeding being effected from the bottom of said stack or
pile. Any preferred form of feeder may be employed, the object being to feed but
one card or envelope at a time. The feeder shown comprises a longitudinally-
movable bar h fitted between guide-plates and having a threaded lug or post h²
through an opening in which is passed a rod h³, which is firmly bound at the desired
point by a screw h working in a vertical hole in post h². Upon the outer end of this
rod h³ is loosely mounted a plate having eye-loops ho through which the rod is
passed. A pin h limits the rocking movement of the plate in either direction and
said pin and flange * on said rod prevent plate h moving longitudinally on rod h³.
From this plate h³ project, or they may be formed integral therewith, shouldered
plates having inclined ends h". Against the top or inclined portions of the
shoulders of these plates are designed to bear the free ends of longitudinally
adjustable plates 2, held by screws h¹³ passed through slots 4. The adjustment is
effected by the beveled heads of screws ha engaging the ends of the plates, the screws
serving to securely hold the plates after being adjusted. The ends of these plates are
designed to engage and shove forward the cards or envelopes one at a time and the
extent of projection of the ends of these plates above the shoulders is regulated by the
longitudinal adjustment thereof. According to the thickness of the cards or envelopes
the ends of the plates h¹² are caused to project a greater or lesser degree above the
shoulders . It frequently occurs that packages of envelopes are bent or twisted,
and will not rest flat on the feed-table, but by loosely mounting the plate the
feeder is free to conform to such irregularity and thus ensure contact with the
envelopes. A slight modification of the feeder is shown in Figures 19 to 21. But one
plate 15 is mounted on the rod and to it is secured, or it may be formed integral
therewith, one end of a plate h¹. A screw h" regulates the extent to which the free
end of this plate h¹ is raised above or lowered below the shoulder ". The pile of
cards, etc. is held in proper position by upright rods held by collars h
adjustable on two cross-roads i, i, extended over the table and mounted at their
ends in posts. The feeder-bar h is given a reciprocating movement by any suitable
means, but preferably by a shaft is mounted in posts and having a depending

page_text: arm fitting in a slot is said feeder-bar. To an arm on the outer end of this
shaft is connected one end of a pitman ', the other end of which is connected to a
disk on the journal of the impression-cylinder.
I is the regulator for controlling the passage of cards, etc. to the press, it being
located at the inner or forward end of the feed-table in the line of passage. Mounted
on the cross-rod i, at or near the centre thereof, is a post i', in the front grooved face
of which is fitted a vertically-adjustable bar 2, which is held in place by a removable
strip 10.
In this bar is an opening in which fits a horizontal disk or wheel 18 fast
on an adjustable rod which works in a threaded opening in the post . By inserting
any suitable tool in the grooved end of this rod the latter may be turned to
control the height of the bar ", the lower end of which latter is movable within a
short distance of a beveled block or raised surface of the feed-table. To the rear
side of the bar is secured a rearwardly and downwardly extended arm j, to the free
end of which is pivoted the rear end of the approximately horizontal portion of a
tongue, the forward portion of which is slightly curved backward and extended
up in rear of the bar ". This tongue has but a limited movement, by reason of
contact with the bar and arm. A spring serves to normally hold this tongue in
its lowered position, that is, almost in contact with the block . The bar "being
properly adjusted the tongue j' will give sufficiently to allow but one card or envelope
at a time to pass to the press. The tongue is free to move sufficiently far to allow for
the increased thickness at certain points in an envelope and being usually made of
metal is not affected by constant use, and is positive in its operation. By means of
the adjusting screw the bar and tongue can be easily adjusted to a nicety, completely
controlling the passage to the press. To the rear face of the post is connected the
upper end of a finger J, the lower forked end J' of which is slightly curved and
extended rearward on a line with the lower end of the feed-controller.
At one
K is one of the feed-shafts for carrying the cards, etc. forward and giving an
accelerated movement to them, as they are fed to the press, the same having
peripheral enlargements which are designed to be thrown into contact with similar
enlargements of an upper shaft K¹ by a slight rocking of said shaft K. In this way in
connection with the ordinary tapes of the press, the cards, etc. are carried to the stops f"
of the impression cylinder at a speed greater than the face-speed of said cylinder.
This shaft K extends across the frame and its normal position is on a plane slightly
below the lower end of the forked finger and the line of passage to the press.
end it is provided with a pinion K2 which meshes with a similar pinion K³ on shaft K¹
so as to cause them to revolve in unison, the journal of the shaft K¹ being driven by
the gearing mechanisin on one side of the frame. The teeth of these pinions are
sufficiently deep to prevent disengagment when the shaft K is lowered, which latter is
but a small fraction of an inch. Upon shaft K, at a point beneath the forked finger
and between the peripheral enlargements, is a loosely mounted sleeve k from which
extend two parallel ears ¹ between which is pivotally mounted a lever k2 by means of
a short rod k³. The upper short arm of this lever is slightly curved and extended
rearward over shaft K and in line with the space or opening in the end of the finger J.
To the lower end of the long arm of this is articulated the upper end of a sliding lever L
having at said end and its centre slots and l¹. In the former projects a stud l² on the
lower end of lever ² while through the slot 1 is passed the fulcrum screw 13 which
holds the lever L to a lug or projection of the frame A, the same being above the lug
or projection do. A spring serves to hold the lever L in its uppermost position. On
one side of the lower end of this lever is a lug which is normally directly over a
shoulder d of the trip-block d³. Hence a straight downward movement of lever L
will result in the disengagement of the trip-block d³ from the arm d².
M is a rock-shaft extended longitudinally through the frame A parallel with and
between the shafts C and K. On one end of this shaft M is keyed: an arm m carrying
a roller m² at its upper free end which is designed to be engaged by the cam or
shouldered disk b', whereby said shaft is periodically partially rotated. At about the
center of this shaft is keyed an arı m² from one side of which projects a lug m³
between which and the shoulder dx of the trip-block sufficient space is left to permit

page_text: the lug of lever L to move out and back when said lever and the lever ² are moved
on their fulcra. To a lug on the other side of the outer end of this arm m² is connected
the lower end of a rod or pitman m', which at its upper end is connected to a pivoted
rocking-arm m³ centrally fulcrumed at m' on the frame-lug or projection l' and to the
other end of this arm m³ is connected the lower end of a second rod or pitinan m³,
In practice, the rocking of
which at its upper end is connected to the pivot-rod /³.
the shaft M will cause the arm m² to move downward pulling on the rod m', which
through rocking-arm m³ will raise rod m³, resulting in the upward movement of the
ears as the sleeve is moved on shaft K. This movement of the parts occurs at the
point when a card or envelope is, or should be, passing beneath the forked finger J.
If such card or envelope is in position the arm or lever k² will contact therewith and
be lowered, resulting in said lever turning on its fulcrum k³ and its lower end will
throw the upper end of lever L outward, the lower end thereof being swung inward
carrying its lug l out of the way of the lug m³, which travels to within a short distance
of, but does not contact with, the shoulder dx of the trip-block. In this way the latter
is not disturbed so long as the cards, etc. are being properly fed to the press, and as
the arm m² is raised by the return movement of the shaft M the sleeve k resumes its
normal position, as do also the levers k², and L, under the action of the spring l³. If,
on the other hand, a card or envelope should not be fed or properly positioned when
the shaft M is partly rotated the arm of the lever will move upward through the
slot or opening in the forked finger J, and failing to be turned on its pivot, as before
described, the lever I will retain its usual vertical position, and the lug m³ of arm m²
striking against the lug of lever L will force the latter downward against the
shoulder of the trip-block causing the latter to turn on its pivot and free the
arm d² of shaft C, permitting the latter to turn under the action of its spring,
resulting in the lowering of the impression-cylinder and the unclutching of the
clutch-pulley, all as above fully set forth. The lever L, being slotted at its fulcrum is
free to move downward a slight extent when depressed by arin m², but as soon as this
arm is raised the levers k² and I will assume their normal positions. On the projecting
ends of rock-shaft M adjacent the sides of the frame are keyed the hubs n, n, of
arms n¹ to which are connected the lower ends of two spring-held rods n², the upper
ends of which are pivoted to arms n' on the outer end of short shaft nt, mounted in
bearings in the sides of the frame. On the inner ends of these latter shafts are short
arms which form the bearings for the shaft K by which the latter is slightly raised
and lowered. The spring n encircling rods n bear at their lower ends against
apertured lugs n' extending from frame A and through holes in which said rods are
passed. By the means described the free end of arm m is constantly held in contact
with the cam or shouldered disk b', and the shaft K is normally held lowered. These
springs also serve to return the shaft M to its normal position as soon as the arm mis
free of the shoulder on cam b'.
N designates a receptacle for receiving the cards or envelopes as discharged from
the press.
It is of circular form and has a central depending shaft n* mounted in an
outwardly extended arm n" of the press-frame. Concentric with the outer rim 10 of
this receptacle is an inner circular rim n" near the centre thereof, thus forming two
compartments 13 and 14, the former receiving all properly printed cards, etc. while
those not so printed are deposited in the latter. The cards, etc. engaging the blocks G
are caused to fall into the compartment n¹s of the receptacle, but when any
interruption or mistake occurs and the impression-cylinder is shifted, at the same
instant tapered arms are thrown down against shaft g and their free ends extending
over to the impression-cylinder beyond the blocks G, the card or envelope striking
against any one of said arms will slide thereover and be deposited in the central
compartment n" of the receptacle. These arms are mounted on a shaft o loosely
held by depending supports o', and having at one end an arm o³ to which a pitman 03
is connected, the other end of said pitman being eccentrically connected to one end of
shaft C. In this way as said shaft is permitted to partly rotate when tripped to effect
the operation of the "stop" and "throw-off" mechanism the arms 0 are lowered so
as to direct the discharge of the card or envelope not properly printed. This receptacle

page_text: is slowly rotated on its pivot arm by a spring pressed rod or pawl of passed through a
bracket supported by arm n. This rod or pawl is connected to the lower end of a
lever o fulcruined at o to frame A, the free end being engaged by cam 6' on the
journal of cylinder a³.
The
P is the inking-cylinder designed to engage the form-rolls which ink the type-plates
of the cylinder a and effect the thorough inking thereof. The length of this cylinder
is not so great as the space between the sides of the frame, the object being to permit
said cylinder to travel back and forth between said sides to the limit of its movement
at the same time that it is being revolved in contact with the form-rolls.
journal p of this cylinder is extended through the sides of the frame and on one end
is provided with a small toothed wheel p', while on its other end is a gear-wheel på
which meshes with and derives its motion from a wide gear-wheel p³. This latter
wheel is thus made so that the engagement therewith of the wheel p will be
constantly maintained notwithstanding the longitudinal movement of the ink-cylinder
and its journals. With the toothed wheel p' engages the toothed periphery of an
irregularly-bent or cam-like-wheel p* mounted on a stub p' extended from one side of
the frame. As the cylinder is rotated the wheel p' on the journal p thereof engaging
with the irregular wheel p' is moved back and forth longitudinally, thus thoroughly
distributing the ink over the form-rolls.
R is the ink-trough over whose bottom is a plate rendered adjustable by
screws working in holes in said bottom. Over the outlet end of this trough is
located a fountain roll 12, and on one end of the journal thereof is a ratchet-wheel 23
adjacent to which is a loose collar from which depends a slotted arm. To an
upper projection of this arm is pivoted a pawl 7, which by gravity is constantly
held in engagement with the ratchet-wheel r³. To the slotted arm is connected
one end of a pitinan, the other end of which is mounted eccentrically on the
wheel p', the revolution of which will swing arm, causing the pawl through the
ratchet-wheel to turn the roll 2. On the collar 4 is a flat or beveled shoulder s.
S is a second or distributing ink-roller, whose journal & is supported in the
grooved ends of arms sa mounted on a transverse shaft 83 supported in the sides of the
frame, and upon one end of this shaft is keyed an arm 8+. The upper end of this arm
is provided with a rounded recess 8 and a shoulder 8". In this recess is located a
blocks having a rounded portion 8 and a flat portion 8° whose outer end is beveled.
A spring & serves to normally hold this block & in contact with shoulder 8", as shown
in Figure 10. As the collar is rotated, simultaneously with the roll 2, (which
carries out a fresh supply of ink), by the forward movement of arm³, the shoulder 8
engages the end of the block s and forces arms & outward and through shaft 8³
arms & will throw ink-roll S up to contact with the freshly inked surface of fountain
roll . In the return movement of arın ", the friction of the edge of block 87 against
shoulder & is sufficient to overcome the spring 810, causing said block to be lifted and
allowing arm 8 to return to its normal position at the start of the return movement
of shoulder 8. Thus the ink roller S is at once dropped into contact with the ink-
cylinder and allowed to so remain during the time the collar is on its return
movement and until the shoulder 8 again engages the block.

While we have shown and described our improvements in connection with presses
for printing cards and envelopes, yet it will be understood that we do not restrict
ourselves in this particular, since many features are applicable to other presses,
including those from which the printing is on paper supplied from webs or
continuous rolls. Changes may be made in the details of construction without
departing from the scope of the invention. By the term "tripping-device" we mean
inechanically operated means which will be intermittently operated and have a
movable member designed to be thrown across the line of passage of the article to
be printed, and upon engagement therewith so act on its adjuncts as not to disturb
the operation of the press, but in the event of not contacting with such article, or the
latter is not properly positioned, aid in unseating some movable member, allowing
the impression-cylinder to be shifted or causing the press to cease operation, or both.
While we have specified the "throw-off" mechanisin as being capable of lowering

page_text: mechanism is described as
the impression-cylinder in the event of any irregularity in the feed to the press, yet
we mean to include any shifting of said cylinder which will throw it out of
operation. It will also be noted that the "stop
embracing a clutch-pulley, but it is obvious that the same means may be employed,
with possibly slight additions, for shifting a belt from a fast to a loose pulley.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
with a
1. In a printing-press, having its type-carrying cylinder formed
longitudinal peripheral cut-out and a series of circumferential and longitudinal
T-grooves, a series of clamps consisting each of an inner slightly curved plate
having a lug on its outer surface adjacent to one end, an outer plate also slightly
curved and beveled at one end and provided on its underside with a rib and formed
with a recess at one end to accommodate said lug, and a binding screw at the other
end for uniting said plates, substantially as set forth.
2. In a printing-press, the combination with an impression-cylinder and eccentric
bearings therefor, of means tending to normally turn said bearings so as to move the
impression-cylinder away from the type-carrying cylinder, said means comprising a
spring-impelled shaft to which said bearings are connected, a trip for normally
restraining said shaft, and devices intermittently-operated and adapted to actuate
the trip in the event of any irregularity in the feed to the press, substantially as
set forth.
3. In a printing-press, the combination with an impression-cylinder and eccentric
bearings therefor, of means tending to normally turn said bearings so as to move
the impression-cylinder away from the type-carrying cylinder, a trip for normally
restraining said means, an intermittently-operated shaft having an arin or projection
movable in line with said trip but not engaging therewith, and a lug, or the like,
normally filling the space between said trip and said arm or projection, and a device
designed to move said lug out of its normal position only in the event of the stock
being properly fed, whereby if said lug is not so moved said arm or projection will
free said trip, substantially as set forth.
4. In a printing-press having throw-off and stop-mechanism, a spring-impelled
shaft designed to effect the operation thereof, a trip for normally holding said shaft,
a second shaft intermittently operated having an arm or projection movable in line
with said trip-block, and a device capable of being raised and lowered by said second
shaft having a swinging portion the upper end of which is designed to engage or
contact with the card, envelope or paper being fed to the press, its other end being
designed to swing into and out of, the line between said arın or projection and said
trip-block, substantially as set forth.
5. In a printing-press having its impression-cylinder eccentrically mounted, a rock-
shaft connected thereto, a trip for holding said shaft stationary in its normal
position, and a mechanical device operated by the rotation of said cylinder and
