Improvements in Side Registers for Paper Feeding Machines.
We, WILLIAM AUSTIN PHILPOTT Jr., of Niagara Falls, in the County of
Niagara, in the State of New York, Manufacturer, and THOMAS ARNOLD
BRIGGS, of Arlington, in the County of Middlesex, in the State of Massachusetts,
Inventor, both in the United States of America, do hereby declare the nature of
this invention to be as follows:-
This invention relates to the automatic side registering devices which are
employed in connection with printing presses and similar machines for correctly
registering sheets of paper before they are fed into the machine.
One of the objects of our invention is to simplify the construction of the side.
registering devices and to render the same more reliable in operation. A further
object is to so contrive these registering devices that they serve also to supplement
the action of the front guides by restoring the sheets to the proper front register
in case they should become displaced by rebounding from the front guides.
In carrying the invention into practice we provide a fixed upright side guide or
registering face which is arranged longitudinally upon the feed table at one side
thereof and against which one of the lateral edges of the sheet is registered. This
guide forms the inner and lower portion of a head which is formed at the front.
or inner end of an upright supporting plate arranged transversely upon the feed
table and secured to a base plate which is in turn secured to the top of the feed
table.
A reciprocating actuating bar is arranged transversely on the feed table under-
neath the head and extending in front and in rear of the same, the feed table
being provided with a transverse groove in which the bar is guided with its
surface substantially flush with the feed table.
A gripping finger is pivoted in the lower portion of the head by a pivot, the
head being recessed or bifurcated in its lower portion for the reception of this
finger. The latter projects with its inner arm beyond the side guide and is
arranged over the actuating bar, so that the inner arm of the finger, in moving
downwardly toward the bar, presses the sheet of paper down upon the bar and
compels the sheet to move with the bar. The inner or front arm of the gripping
finger terminates in a horizontal roller which is adapted to bear upon the sheet
of paper lying between the finger and the bar.
A. downwardly sloping or curved guide is arranged on the side guide on the
receiving side of the gripping finger for directing the front edge of each sheet
downwardly and under the finger.
A spring bolt bears upon the gripping finger in front of its pivot and tends to
force the finger against the bar. This spring bolt is arranged with its lower
portion in an internally screw threaded socket formed in the head of the supporting
plate while its upper portion passes loosely through an adjustable screw plug or
stem engaging in said socket. The spring of the bolt is arranged between the
head of the latter and the inner end of the screw plug. By screwing the plug up
and down in its socket the downward pressure of the spring bolt upon the finger
is increased or diminished and the hold of the gripping finger and bar upon the
paper regulated accordingly.
A lifting lever is provided whereby the gripping finger is raised and retained

page_text: in that position. This lever is pivoted by an horizontal pin to the front side of
the supporting plate and its lower arm is so arranged that when it is swung into
a vertical position, it bears upon the outer or rear arm of the gripping finger, and
depresses the same, thereby raising the inner end of the gripping finger while
when the lower arm of the lifting lever is swung upwardly and outwardly out of
its perpendicular position it releases the arm of the gripping finger and allows the
spring bolt to depress the finger.
A vertically swinging locking lever is pivoted to the supporting plate in rear
of the lifting lever and having its front arm connected with the rearwardly
extending upper arm of the lifting lever by a link, so that when the rear arm of
the locking lever is swung upward, its front arm depresses the upper arm of the
lifting lever, through the medium of the liuk thereby swinging the lower arm of
the lifting lever forwardly into the locked position in which it depresses the rear
arm of the gripping finger. The lower arm of the lifting lever is provided with
an outwardly projecting shifting lug and the lower arm of the locking lever is
also provided with a shifting lug the two lugs being in substantially the same
vertical plane.
A trip pawl is carried by the bar and adapted to engage against the shifting lugs
of the lifting and locking levers successively during the backward or outward
stroke of the bar so as to swing said levers on their pivots. The pawl, during its out-
ward movement with the bar, first swings the lower arm of the lifting lever outwardly
so as to release the gripping finger and allow it to descend under the pressure of
its spring bolt, and it then engages against the lower arm of the locking lever and
trips the latter so as to cause said lever to return the lifting lever to its locked
position and raise the gripping finger.
The trip pawl is provided at its inner or free end with a head or nose having
an abrupt outer or rear face and a bevelled inner or front face and the lug of the
lifting lever has a corresponding inner abrupt face and an outer bevelled face.
The pawl is made laterally yielding so that upon the inward or forward stroke of
the bar, the bevelled face of the pawl rides inwardly over the bevelled face of the
lifting lever without affecting the latter. For this purpose the pawl is pivoted at its
outer end upon a vertical pin and is provided with a return spring which tends
to press the pawl into the path of the shifting lugs of the lifting and locking
levers.
The trip pawl and its spring are preferably mounted on a plate which is adjust-
ably secured to the bar. This plate is provided on its underside with an undercut
or dovetail groove which receives the correspondingly shaped bar and the plate is
split and clamped to the slide by a transverse bolt which passes through perforated
lugs formed on the plate on opposite sides of its slit.
A stop pin is arranged on the plate in front of the trip pawl and serving to limit
the movement of the pawl toward the shifting lugs.
A reciprocating movement is imparted to the bar by any suitable means. In the
construction herein described the bar is actuated by a forked rock arm secured to
an upright rock shaft and engaging with a pin secured to the bar said rock shaft
being in turn operated from a cam mounted on the shaft of the press cylinder, by
a connecting rod attached at its outer end to an arm of the rock shaft and provided
at its opposite end with a pin which engages in the groove of the cam.
In order to stiffen the paper and prevent breaking or wrinkling thereof by
contact with the side guides, the paper may be bent, arched or corrugated trans-
versely at its lateral edges. For this purpose, the upper surface of the reciprocating
bar is made convex or crowning and the underside of the inner arm of the gripping
finger is made correspondingly concave.
The operation of our improved side registering device is as follows:-
While the sheet is being fed forward over the feed board against the front
guides, the bar is at rest at the extremity of its outward stroke, the trip pawl
stands outside of the locking lever, the lower arm of the lifting lever is in engage-
ment with the rear arm of the gripping finger and the latter is elevated allowing

page_text: the sheet of paper to be fed forward under the gripping finger and against the
front or drop guides of the press. When the sheet has come in contact with said
guides the bar moves inwardly and during this forward stroke of the bar the trip
pawl slips by the lugs of the locking and lifting levers without disturbing the
same. After the head of the tripping pawl has passed inwardly by the lug of the
lifting lever the movement of the bar is reversed. During the initial portion of
this outward or reverse stroke, the trip pawl engages first against the abrupt face
of the lug of the lifting lever and swings the latter on its pivot so as to release
the gripping finger and allow the spring bolt to depress the finger, whereby the
adjacent marginal portion of the sheet is pressed by the roller of the finger against
the upper surface of the bar. The frictional resistance between the bar and the
paper is greater than that between the roller and the paper and the sheet is,
therefore, drawn against the side guide by the continued outward movement of
the bar. As soon as the edge of the sheet comes in contact with the side guide it
is arrested, while the bar continuing its movement, slips along the underside of the
sheet until the bar reaches the end of its outward stroke and position of rest.
The trip pawl immediately after releasing the lifting lever encounters in its
outward movement the lug of the locking lever and by engaging against the
iuner face of said lug swings the locking lever thereby causing the locking lever
to return the lifting lever to its locked position, and again raising the gripping
finger and releasing the registered sheet, which latter is now seized by the nippers
of the printing press.
By means of the adjusting stem the pressure of the gripping finger can be
regulated with nicety in accordance with the thickness, stiffness and smoothness of
the paper.
In order to enable the side guide to be adjusted laterally to accommodate sheets
of different widths the base plate which carries the supporting plate and the
lifting and locking levers is made adjustable transversely on the feed board by
means of a vertical clamping bolt which passes through an opening in the feed
table and a longitudinal slot formed in the base plate. This bolt is provided
with a thumb nut which bears upon a washer or thimble resting upon the base
plate. Upon loosening this thumb nut, the base plate with the side guide and the
other parts carried thereby can be adjusted laterally on the feed table, the nut
being again tightened after affecting the adjustment. If desired, the range of
adjustment of the parts may be increased by providing the table with a transverse
row of openings in any one of which the clamping bolt may be placed after
removing its nut.
In addition to the two comparative coarse adjustments just described, the side
guide is preferably provided with means for making a slight or fine adjustment
which does not require the base plate to be shifted. For this purpose, the
supporting plate is made lengthwise adjustable on the base plate by means of a
longitudinal adjusting screw which is held against endwise movement in a lug or
flange formed at the rear end of the supporting plate and which engages with an
internally screw threaded lug formed on the upper side of the base plate.
A horizontal set screw is provided whereby the supporting plate is clamped in
place after adjustment and whereby its front portion is held against the base plate.
This set screw passes through a horizontally slotted lug formed on the upper front
portion of the base plate and engages in an internally screw threaded socket formed
in the adjacent rear side of the supporting plate. Upon loosening this set screw
and turning the adjusting screw in one or the other direction, the supporting plate
with the side guide and other parts connected therewith are adjusted forward or
backward accordingly.
A sheet of paper on striking the front guides is liable to rebound therefrom into
a more or less oblique position, destroying its front register. In order to straighten
such displaced sheets before they are side registered, we combine two of our
improved side registering devices in such a manner that the gripping device at the
off side of the feed board seizes the sheet first and draws it to vard the off side of

page_text: the feed board during the forward stroke of the carrier bar, while the gripping
device on the near side of the feed board seizes the sheet after the first mentioned
device has released the same and draws the sheet back against the side guide against
which the sheet is side registered. By the term "near side" of the feed board we
refer to the side on which that gripping device is arranged against which the sheet
is ultimately side-registered, and by the term "off side" the opposite side on which
no side register is effected. In other words, the sheet is first moved away from
that side guide against which it is ultimately side registered and is then drawn
back against the registering side guide. This movement of the sheet away from
the registering side guide causes the retarded front corner of the sheet to be swung
forwardly against the adjacent front guide, when the retarded corner of the sheet
is adjacent to the side registering guide, while when the foremost corner of the
sheet is adjacent to the side-registering guide, the movement of the sheet away
from said guide has a tendency to swing the foremost corner of the sheet back-
wardly and the subsequent movement of the sheet toward the side registering guide
swings the retarded corner of the sheet forwardly into proper front register. The
right hand side guide is the one against which the sheet is to be side registered
and is on the near side of the feed board. During the forward stroke of the
actuating or carrier bar the gripping device on the left hand or off side of the feed
board draws the sheet away from the side guide on the right hand or near side and
swings the retarded front corner of the sheet forwardly against the adjacent front
guide, and so restores the front register. The gripper engages with the edge of
the sheet in such manner that the sheet swings on the point of engagement between
the gripper and the sheet as a pivot while being moved with its retarded front
corner against the front guide. During the return stroke of the carrier bar the
gripping device on the right hand side of the feed board moves the sheet against
the registering side guide and side registers the sheet.
In one form the carrier bar moves forwardly the sheet is seized by the gripping
device, on the off side of the feed board and the sheet is thereby moved away from
the side registering guides on the near side of the feed board preparatory to its
return movement toward said side registering guide.
In order to swing displaced sheets into front register the gripping devices should
be so arranged as to seize the sheets not very far in rear of the retarded front
corners. The side registering guides are preferably duplicated so that sheets can
be registered on either side of the feed board, as may be most convenient but it is
not necessary that the sheets should be moved against the side guide on the off
side of the feed board during the forward stroke of the carrier bar and that side
guide may be dormant and inay be omitted when the sheets are only registered on
one side of the feed board.
The side registering devices are duplicated at opposite sides of the feed table
and the actuating or carrier bar extends across the feed board and carries two trip
pawls, one for each side registering device. The two devices are arranged reversely
or with the side guides gripping fingers and trip pawls facing each other. By this
reverse arrangement of the two registering devices, the two gripping fingers are
depressed alternately, one finger being depressed during the inward or forward
stroke of the bar and the other during the return stroke.
If a sheet does not rebound from the front guides but remains in correct front
register, it is simply moved first away from the side registering guide and then
against the same without disturbing its front register.

page_text: We, WILLIAM AUSTIN PHILPOTT Jr., of Niagara Falls, in the County of
Niagara, in the State of New York, Manufacturer, and THOMAS ARNOLD BRIGGS,
of Arlington, in the County of Middlesex, in the State of Massachusetts, Inventor,
both in the United States of America, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to the automatic side registering devices which are
employed in connection with printing presses and similar machines for correctly
registering sheets of paper before they are fed into the machine.
One of the objects of our invention is to simplify the construction of the side
registering devices and to render the same more reliable in operation. A further
object is to so contrive these registering devices that they may serve also to supple-
ment the action of the front guides by restoring the sheets to the proper front
register in case they should become displaced by rebounding from the front guides.

Figure 8 is a similar section, on an enlarged scale, on line 8-8, Figure 3.
Figure 9 is a front elevation showing both connected registering devices in the
positions which they occupy during the forward stroke of the reciprocating bar by
which both grippers are operated.
Like letters of reference refer to like parts in the several figures.
A Figures 1 and 2 represents the feed board or table upon which the sheets of
paper are successively fed from a pile by any suitable or well known means. B is
the cylinder of a printing press, and c are the usual front or drop guides of the
press against which the front edge of the sheet is registered.
D Figures 1, 2, 3 and 9 is a fixed upright side guide or registering face which is
arranged longitudinally upon the feed table at one side thereof and against which
one of the lateral edges of the sheet is registered. This guide forms the inner and
lower portion of a head D' which is formed at the front or inner end of an upright
supporting plate E arranged transversely upon the feed table and secured to a base
plate F which is in turn secured to the top of the feed table.
G is a reciprocating actuating bar arranged transversely on the feed table under-
neath the head D₁ and extending in front and in rear of the same, the feed table
being provided with a transverse groove g Figures 3, 4 and 5 in which the bar is
guided with its surface substantially, flush with the feed table.
H Figures 7 and 9 is the gripping finger which is pivoted in the lower portion of
the head D¹, by a pivot h, Figure 9, the head being recessed or bifurcated in its
lower portion, as shown at h', Figures 4 and 7 for the reception of this finger.
The latter projects with its inner arm beyond the side guide and is arranged over

page_text: the actuating bar, so that the inner arm of the finger, in moving downwardly toward
"the bar, presses the sheet of paper down upon the bar and compeis the sheet to
move with the bar. The inner or front arm of the gripping finger terminates in a
horizontal roller 2 which is adapted to bear upon the sheet of paper lying between
the finger and the bar.
3 Figures 3, 4, 5 and 7, is a downwardly sloping or curved guide arranged on
the side guide on the receiving side of the gripping finger for directing the front
edge of each sheet downwardly and under the finger.
i Figure 4, is a spring bolt which bears upon the gripping finger in front of its
pivot and which tends to force the finger against the bar. This spring bolt is
arranged with its lower portion in an internally screw threaded socket i formed in
the head D' of the supporting plate E while its upper portion passes loosely
through an adjustable screw plug or stem engaging in said socket. The spring
of the bolt is arranged between the head of the latter and the inner end of the
screw plug. By screwing the plug up or down in its socket the downward pressure
of the spring bolt upon the finger is increased or diminished and the hold of the
gripping finger and bar upon the paper regulated accordingly.
Figures 3 and 4 is a lifting lever whereby the gripping finger is raised and
retained in that position. This lever is pivoted by a horizontal pin to the front'
side of the supporting plate. E and its lower arm is so arranged that when it is
swung into a vertical position, it bears upon the outer or rear arm of the gripping
finger, and depresses the same, thereby raising .the inner end of the gripping finger,
as shown in Figure 3, while when the lower arm of the lifting lever is swung
upwardly and outwardly out of its perpendicular position, as shown in Figure 4, it
releases the arm of the gripping finger and allows the spring bolt to depress
the finger.
K is a vertically swinging locking lever pivoted to the supporting plate E in rear
of the lifting lever J Figure 6 and having its front arm connected with the
rearwardly extending upper arm of the lifting lever by a link l, so that when the
rear arm of the locking lever is swung upward, as shown in Figure 3, its front arm
depresses the upper arm of the lifting lever, through the medium of the link
thereby swinging the lower arm of the lifting lever forwardly into the locked
position in which it depresses the rear arm of the gripping finger. The lower arın
of the lifting lever is provided with an outwardly projecting shifting lug and the
lower arm of the locking lever is provided with a shifting lug k, the two lugs being
in substantially the same vertical plane.
M Figures 3, 4, 5 and 9 is a trip pawl carried by the bar and adapted to engage
against the shifting lugs of the lifting and locking levers successively during the
backward or outward stroke of the bar so as to swing said levers on their pivots.
The pawl, during its outward movement with the bar, first swings the lower arm
of the lifting lever outwardly so as to release the gripping finger and allow it to
descend under the pressure of its spring bolt, as shown in Figure 4, and it then
engages against the lower arm of the locking lever and trips the latter to the
position shown in Figure 3, so as to cause said lever to return the lifting lever to its
locked position and raise the gripping finger.
The trip pawl is provided at its inner or free end with a head nose having an
abrupt outer or rear face m and a bevelled inner or front face m' and the lug of the
lifting lever has a corresponding inner abrupt face and an outer bevelled face, as
most clearly shown in Figure 5. The pawl is made laterally yielding, so that upon
the inward or forward stroke. of the bar, the bevelled face of the pawl rides
inwardly over the bevelled face of the lifting lever without affecting the latter.
For this purpose the pawl is pivoted at its outer end upon a vertical pin m² and is
provided with a return spring m³ which tends to press the pawl into the path of the
shifting lugs of the lifting and locking levers.
The trip pawl and. its spring are preferably mounted on a plate N Figures 3, 4
and 5 which is adjustably secured to the bar. This plate is provided on its underside
with an undercut or dovetail groove n Figure 8 which receives the correspondingly

page_text: shaped bar and the plate is split and clamped to the slide by a transverse bolt n³
which passes through perforated lugs formed on the plate on opposite sides of its
slit. as shown in Figures 3, 4 and 8.
n2 is a stop pin arranged on the plate N in front of the trip pawl and serving to
limit the movement of the pawl toward the shifting lugs.
A reciprocating movement is imparted to the bar by any suitable means.
In the
construction shown in the drawings, the bar is actuated by a forked rock arm o
secured to an upright rock shaft o' and engaging with a pin o secured to the bar,
said rock shaft being in turn operated from a cam P mounted on the shaft of the
press cylinder, by a connecting rod p attached at its outer end to an arm o³ of the rock
shaft and provided at its opposite end with a pin p' which engages in the groove of
the cam.
In order to stiffen the paper and prevent breaking or wrinkling thereof by contact
with the side guides, the paper may be bent, arched or corrugated transversely at
its lateral edges. For this purpose the upper surface of the reciprocating bar is
made convex or crowning and the underside of the inner arm of the gripping finger
is made correspondingly concave, as shown in Figure 7.
The operation of our improved side registering, device is as follows:-
While the sheet is being fed forward over the feed board against the front
guides, the bar is at rest at the extremity of its outward stroke, the trip pawl
stands outside of the locking lever, the lower arm of the lifting lever is in engage-
ment with the rear arm of the gripping finger and the latter is elevated, as shown
in Figure 3, allowing the sheet of paper to be fed forward under the gripping
finger and against the front or drop guides of the press. When the sheet has come.
in contact with said guides the har moves inwardly and during this forward stroke
of the bar the trip pawl slips by the lugs of the locking and lifting levers without.
disturbing the same. After the head of the tripping pawl has passed inwardly by
the lug of the lifting lever the movement of the bar is reversed. During the initial
portion of this outward or reverse stroke, the trip pawl engages first against the
abrupt face of the lug of the lifting lever and swings the latter on its pivot so as
to release the gripping finger and allow the spring bolt to depress the finger,.
whereby the adjacent marginal portion of the sheet is pressed by the roller of the
finger against the upper surface of the bar. The frictional resistance between the
bar and the paper is greater than that between the roller and the paper and the sheet.

the bar. As soon as the edge of the sheet comes in contact with the side guide it.
is arrested, while the bar continuing its movement, slips along the underside of the
sheet until the bar reaches the end of its outward stroke and position of rest..
The trip pawl immediately after releasing the lifting lever encounters in its outward
movement the lug of the locking lever and by engaging against the inner face of
said lug swings the locking lever into the position shown in Figure 3, thereby-
causing the locking lever to return the lifting lever to its locked position, shown in
the same figure, and again raising the gripping finger and releasing the registered
sheet, which latter is now seized by the nippers of the printing press.
By means of the adjusting stem Figures 4, 6 and 9 the pressure of the gripping.
finger can be regulated with nicety in accordance with the thickness, stiffness and
smoothness of the paper.
In order to enable the side guide to be adjusted laterally to accommodate sheets.
of different widths the base plate F which carries the supporting plate E and the
lifting and locking levers, is made adjustable transversely on the feed board by
means of a vertical clamping bolt q which passes through an opening in the feed
table and a longitudinal slot q' formed in the base plate, as shown in Figures 5 and 6.
This bolt is provided with a thumb nut q2 which bears upon a washer or thimble q³-
resting upon the base plate. Upon loosening this thumb nut, the base plate with
the side guide and the other parts carried thereby can be adjusted laterally on the
feed table, the nut being again tightened after affecting the adjustment. If desired,.
the range of adjustment of the parts may be increased by providing the table with.

page_text: a transverse row of openings 9, as shown in Figure 5, in any one of which the
clamping bolt q may be placed after removing its nut.
In addition to the two comparatively coarse adjustments just described, the side
guide is preferably provided with means for making a slight or fine adjustment
which does not require the base plate to be shifted. For this purpose the supporting
plate E is made lengthwise adjustable on the base plate by means of a longitudinal
adjusting screw R which is held against endwise movement in a lug or flange r
formed at the rear end of the supporting plate and which engages with an internally
screw threaded lug formed on the upper side of the base plate, as shown in
Figure. S is a horizontal set screw whereby the supporting plate is clamped in
place after adjustment and whereby its front portion is held against the base plate.
This set screw passes through a horizontally slotted lug s, Figure 5 formed on the
upper front portion of the base plate and engages in an internally screw threaded
socket s' formed in the adjacent rear side of the supporting plate. Upon loosening
this set screw and turning the adjusting screw in one or the other direction, the
supporting plate with the side guide and other parts connected therewith are adjusted
forward or backward accordingly.
A sheet of paper on striking the front guide is liable to rebound therefrom into
a more or less oblique position, destroying its front register, as indicated in Figure 1.
In order to straighten such displaced sheets before they are side registered, we
combine two of our improved side registering devices in such a manner that the
gripping device at the off side of the feed board seizes the sheets first and draws
it toward the off side of the feed board during the forward stroke of the carrier
bar, while the gripping device on the near side of the feed board seizes the sheet
after the first mentioned device has released the same and draws the sheet back
against the side guide against which the sheet is side registered. By the term
"near side" of the feed board we refer to the side on which that gripping device is
arranged against which the sheet is ultimately side registered, and by the term
"off side" the opposite side on which no side register is effected. In other words,
the sheet is first moved away from that side guide against which it is ultimately
side registered and is then drawn back against the registering side guide. This
movement of the sheet away from the registering side guide causes the retarded
front corner of the sheet to be swung forwardly against the adjacent front guide,
when the retarded corner of the sheet is adjacent to the side-registering guide,
while when the foremost corner of the sheet is adjacent to the side-registering
guide, the movement of the sheet away from said guide has a tendency to swing
the foremost corner of the sheet backwardly and the subsequent movement of the
sheet toward the side registering guide swings the retarded corner of the sheet
forwardly into proper front register. For instance, as illustrated in Figure 1,
the left hand forward corner of the sheet looking in the direction in which the
sheet moves over the feed board, has stopped against the adjacent front guide and
the right hand corner has been retarded. The right hand side guide is the one
against which the sheet is to be side registered and is on the near side of the
feed board. During the forward stroke of the actuating or carrier bar, in the
direction of the arrow 1, the gripping device on the left hand or off side of the feed
board draws the sheet away from the side guide on the right hand or near side and
swings the retarded front corner of the sheet forwardly in the direction of the
arrow 2, against the adjacent front guide, and so restores the front register. The
gripper engages with the edge of the sheet in such manner that the sheet swings on
the point of engagement between the gripper and the sheet as a pivot while being
moved with its retarded front corner against the front guide. During the return
stroke of the carrier bar the gripping device on the right hand side of the feed
board moves the sheet against the registering side guide in the direction of the
arrow 3, and side registers the sheet.
In Figure 9 the carrier bar moves forwardly in the direction of the arrow, the
sheet is seized by the gripping device on the off side of the feed board, which device
is shown on the right hand side of the figure, and the sheet is thereby being moved

page_text: away from the side registering guide on the near side of the feed board, shown on
the left hand side of the figure, preparatory to its return movement toward said
side-registering guide.
In order to swing displaced sheets into front register the gripping devices should
be so arranged as to seize the sheets not very far in rear of the retarded front.
corners. The side registering guides are preferably duplicated so that sheets can
be registered on either side of the feed board as may be most convenient, but it is
not necessary that the sheets should be moved against the side guide on the off side
of the feed board during the forward stroke of the carrier bar and that side guide.
may be dormant and may be omitted when the sheets are only registered on one
side of the feed board.
The side registering devices are duplicated at opposite sides of the feed table.
and the actuating or carrier bar extends across the feed board and carries two trip
pawls, one for each side registering device. The two devices are arranged reversely
or with the side guides, gripping fingers and trip pawls facing each other, as
shown in Figure 1. By this reverse arrangement of the two registering devices,
the two gripping fingers. are depressed alternately, one finger being depressed
during the inward or forward stroke of the bar and the other during the return
stroke.
If a sheet does not rebound from the front guides but remains in correct front
register, it is simply moved first away from the side registering guide and then
against the same without disturbing its front register.
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 :-
1. The combination with a feed board, of a gripping device consisting of a.
reciprocating bar or carrier and pressing finger which does not partake of the
movement of said bar or carrier but has a movement toward and from the same for
pressing the paper against said bar or carrier and compelling the paper to move
therewith, substantially as set forth.
2. The combination with a feed board, of a side registering guide secured thereto,
and a gripping device consisting of a transversely movable bar or carrier and a
pressing finger which is supported independently of said bar or carrier and does not
partake of its movement but has a movement toward and from said bar or carrier
for pressing the paper against said bar or carrier, substantially as set forth.
3. The combination with a feed board and a side guide, arranged thereon, of a
gripping device consisting of a transversely movable bar or carrier and a pressing
finger which does not partake of the movement of said bar or carrier but is capable
of moving toward and from the same and which is provided with a pressure roller,
substantially as set forth.
4. The combination with a feed' board and a side guide arranged thereon, of a
gripping device consisting of a transversely movable bar or carrier, a pressing
