I, ALFRED GEORGE BROOKES, of 55 and 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
to be as follows:-
This invention relates to apparatus used in double machines for cutting or
cutting and scoring cardboard and the like and is particularly designed to facilitate
the delivery of the sheets of material from the operations of the one set of
cutting or cutting and scoring parts to the next.
The sheet of material having been fed into the machine is passed to and operated
upon by the one set of cutters and scorers in what may be called the longitudinal
direction.
Having passed to the full extent required in that direction the sheet comes into
position to be acted upon by parts which carry it into the operative path of the
cutters and scorers which cut and score it in a direction at right angles to the
first set of such parts.
These parts for so feeding the sheet to. the transverse cutters consist of a blade
or pusher reaching across the table of the machine and constantly kept in recipro-
cating motion to and from the transverse cutters by suitable gearing. The sheet
however is not operated upon by the pusher as it passes through the longitudinal
cutters by reason of its edge nearest the pusher being raised over and riding along
a guard plate swinging suspended by arms from a rail above, these arms also
carry a sliding rod; on said rod is elastically and adjustably mounted a finger or
stop this elastically and adjustably mounted stop is so arranged that it lies in the
path of the advancing sheet and when the sheet has just cleared the first set of
cutters it has come into contact with this stop and moved it and the stop in
moving has moved the rod it is mounted upon and the end of the rod (as soon as
the two parts come into correct position as hereafter described) enters a slot in a
constantly reciprocating part moved by a cam or pattern surface on the pusher
frame and the rod is tripped moving the finger and guard plate from below the
sheet" allowing it to fall into the path of the reciprocating blade or pusher-to
be by said pusher carried in a direction transverse to its original line of travel
to and between the transverse cutters and scorers. Meanwhile the rod and
guard plate parts are reinstated in position for another sheet to be feed along
ready to follow the preceding one from the first set of cutters. This reinstating is
effected by a cam surface at the end of the rod opposite to the reciprocating lifting
part acting on a button or head on the rod and drawing it out of the said lifting
groove and it now drops the parts into their former position and the operations
are repeated.

page_text: The object of the rod and finger being elastically connected is to allow of the end
of the rod pressing against the face of the grooved part on the reciprocating piece
without damage until it truly finds its place in the groove.
Graduated indications on the rail may serve to assist adjustment of the finger.
To assist the pusher in carrying the sheet correctly to the transverse cutters
brushes mounted on guide rods hold down the sheet and traversing therewith
deliver it to the said cutters flat and correctly, whilst the said brushes also serve
as a spring holding down means for the incoming sheet until it drops into the
path of the pusher.
The edges of the sheets in both sides of the machine-that is to say-the
longitudinal and the transverse ends--are cut by means of a circular disc knife
rotating in close contact with the edge of the scoring roller.

Improvements in and relating to Apparatus for Cutting or Cutting
and Scoring Cardboard and the like:
A communication from abroad by MARK DEAN KNOWLTON and FRED HOSMER
BEACH, of 29-35, Elizabeth Street, Rochester, in the State of New York,
United States of America, Paper Box Machinery Engineers.
I, ALFRED GEORGE BROOKES, of 55 and 56, Chancery Lane, in the County of
London, Chartered Patent Agent, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
My invention relates more particularly to that class of scoring machines or
apparatus adapted for double scoring cardboard or similar material, and which
are provided with two sets of scorers or scoring mechanism arranged to score
the cardboard in two directions (usually at right angles to each other) during a
single passage of the same through the machine, a suitable feeding device being
arranged between the two sets of scorers for engaging with the board after it has
been operated upon by the first or primary scorers and automatically feeding it
to the next or secondary scorers.
In the operation of these machines, the sheets of cardboard or other material
are fed one at a time, usually by an attendant, to the primary scorers, and, after
having been passed from the latter, are reach engaged by a reciprocating cross-
feed operating at right angles to the path of movement of the sheet as it passes
from the said primary scorers, and fed thereby to the next or secondary scorers.
In feeding the sheets rapidly and in close succession through the machine, how-
ever, two or more of the sheets are liable to become fouled unless considerable
care is exercised on the part of the attendant in regulating the manual feed
to the primary scorers, or some other provision made to avoid the same.
Therefore, it has been the object of my present invention to provide a simple
and effective means for automatically controlling the passage of the sheets through
the machine whereby possibility of interference between two successive sheets is
avoided.
In carrying my invention into effect, I employ a cross feed for operating upon
the table between the primary and secondary sets of scorers having a continuously

page_text: reciprocating movement, and above the path of such cross-feed suspend a
swinging guard plate or shelf which is arranged parallel with the forward or sheet
engaging edge of the latter. This guard plate receives thereon that edge of the
sheet nearest the cross feed as the sheet passes from the primary scorers upon the
table between the two sets of scorers, and holds the same above the path of the
reciprocating feed so that it will not be engaged and moved thereby until the
preceding sheet has been fed to the secondary scorers and the cross feed has
returned to its normal or starting position, at which time the said guard plate,
operated by suitable mechanism brought into action by the return of the crossfeed,
is swung backward so as to permit the supported edge of the sheet to drop upon
the table and into the path of the cross-feed to be engaged by the latter and fed
forward thereby to the secondary scorers. Such construction and operation of
parts, whereby one sheet is prevented from being acted upon by the reciprocating
cross feed until the latter has moved forward to feed the preceding sheet to the
secondary scorers and returned to its starting position, prevents possibility of
fouling or interference between two successive sheets.
The guard plate normally hangs in a stationary position independent of con-
nection with its backwardly swinging mechanism so as to be in position to receive
the edge of the sheet thereon as the latter passes from the primary scorers, the
backward movement of the guard plate from beneath the edge of the sheet being
controlled by the forward movement of the latter in passing from the primary
scorers, a controller being arranged in the path of the advancing sheet to be
engaged by its forward edge and operated thereby to bring into action certain
mechanism whereby the guard plate will be swung backward from beneath the
supported edge of the sheet at the return movement of the cross feed as before
referred to. As the guard plate is moved back from beneath the edge of the sheet
to permit the latter to drop into the path of the cross feed, further means is
thereby brought into action to cause the quick return of the guard plate to its
normal position to receive the edge of the succeeding sheet entered through the
primary scorers.
!
The features above referred to, and various others, forming part of my inven-
tion, will be hereinafter referred to in detail and pointed out in the claims.

page_text: Fig. 14 is a section through line — Fig. 12.
Figs. 15 22 inclusive, are views illustrating a modification of my invention to
be hereinafter referred to in detail.
To explain in detail-1 represents the supporting frame which may be of any
suitable form or construction, upon which the several working parts of the machine
are supported.
Adjacent to one end of the frame and supported in suitable bearings therein is.
the main driving shaft 2, which latter, as shown, is provided with a pulley
running loosely thereon and adapted to be connected or disconnected therewith
by a suitable clutch 4.
Two shafts and 6, arranged at right angles to each other and each being.
provided with a bed roll thereon forming part of the primary and secondary
scoring mechanisms respectively, are driven from the said driving shaft 2 through
the medium of suitable connections, the shaft 5, as shown, being driven. through
the bevel gears 7, 7, and the shaft 6 through the gears 8, 8. Any suitable means,
however, for operating the shafts 5 and 6, other than that shown and described,
may be employed as found to be most convenient and desirable.
The two scoring mechanisms of which the bed rolls 5 and 6 form part, are of
usual construction, the same consisting of the said bed rolls and the scoring
knives or cutters 9 adapted to cooperate therewith, the knives or cutters being
carried in a detachable and adjustable position on the underside of two swinging
bars 10, 10 which are journalled in suitable bearings on the supporting frame in
position immediately above the bed rolls.
At the rear of the primary scorers and adjacent thereto are located two feed
rolls 11, 11 which are supported at their opposite ends in suitable bearings and
adapted to engage with the leading edge of a sheet as it is fed by an attendant
from the feed table 12 through the primary scorers, and move the same through
the latter and upon the table 13 between the two sets of scorers. These feed
rolls are connected at one end by gears 14, 14 (see Fig. 2) and driven from the
shaft 5 through the medium of gearing 15 and 16.
After the scored sheet has been fed on to the table 13, it is engaged at the
proper time by the reciprocating cross feed 17 operating in a direction at right
angles to the path of movement of the sheet as it passes from the primary scorers,
and moved or fed thereby to the secondary scorers to be scored by the latter in
a direction at right angles to the first score lines. This cross feed, which may be
constructed and operated in any usual and well known manner, consists of the
blade 17 which rests and slides upon the table 13 and is adjustably connected at
one end with a reciprocating cross head 18, which latter is fitted to slide within a
groove 19' formed in the table 13 adjacent to its outer edge.
A link 20, pivotally connected at one end with the supporting frame at 21
and at its opposite end having a loose connection with the said cross head between
two cars 22, 22 on its under side, is operated from an eccentric 23. on the bed
roll shaft 6 through the medium of suitable connections to receive a vibrating
movement and thereby communicate to the cross head 18 its reciprocating move-
ment; the connections between the said eccentric and link being an eccentric
strap 24 and a rod 25 connected at one end with said strap and at its opposite end
with the link 20, as clearly shown in Fig: 3.
As the sheet is fed onto the intermediate table from the primary scorers, that
edge nearest the cross feed 17 is received upon the guard plate 26 which is arranged
parallel with the forward or sheet engaging edge of the cross feed, and supported
thereby above the path of the latter so as not to be engaged by the same until
a certain predetermined time, at which time the guard plate is automatically
swung backward to permit the supported edge of the sheet to drop upon the table
and into the path of the cross feed, by means as will be described.
The guard plate 26 is supported by two arms 27. 27 just a sufficient distance
above the table to permit of the free clearance of the reciprocating cross feed
thereunder, the said arms being pivotally supported upon a rod 28 (see Figure 4)

page_text: which is arranged above the table 13 and seated at its opposite ends within
bosses formed on two collars or sleeves, indicated at 29 and 30, which latter are
supported in a sliding adjustable position upon two cross rods 31 and 32 suitably
supported above the table near its opposite edges.
Upon the rod 28 between the two guard plate supporting arms 27, 27, is loosely
supported a sleeve or collar 33 having a downwardly extending bracket arm 34,
from which latter is pivotally suspended a finger 35 the lower end of which hangs
slightly below the upper surface of the guard plate at the forward edge thereof,
as more clearly shown in Figs. 4, 8 and 9, so as to lie in the path of the leading
edge of a sheet being fed onto the table 13 and be engaged thereby. A rod 36,
loosely extending through an opening in the lower end of the bracket arm 34 and
being supported at its ends within openings in the opposite guard plate supporting
arms 27, 27, so as to be capable of having a sliding longitudinal movement therein,
is provided with a loose collar 38 thereon at a point opposite the finger 35 having
a pin 39 loosely extending through a vertically elongated slot 40 in said finger.
as more clearly shown in Figures 4 and 9. Longitudinal movement of this
collar 38 on the rod 36, as given by the action of the connected controller finger 35,
is limited between two connected rings 41, 41, which latter are held in an
adjustable stationary position on said rod by a set screw 42. Between one of the
said rings 41 and the rear end of the collar 38 is located a light coiled spring 43.
By means of such described connection between the longitudinally movable rod 36
and the pivotally suspended controller finger 35, when the latter is engaged by the
leading edge of the sheet being fed onto the table 13 (which engagement occurs
about as the sheet clears the primary scorers), it is moved by such sheet, as
indicated by dotted lines in Fig. 4, and in so moving has moved the yieldingly
connected rod 36 and caused one end of the same to project beyond the edge of
its supporting arm 27 and enter a slot or groove 44 in a constantly vibrating
lever 45, in which groove it is engaged by the end wall thereof and carried
backward to swing the guard plate from beneath the edge of the supported sheet
and permit the latter to drop into the path of the cross feed, as shown in Fig. 9.
In the latter figure, one edge of a sheet, indicated at a and shown in dotted lines,
is represented as resting upon the guard plate with the controlling finger in
the path of the same, and the position of the parts as taken upon their backward
throw or movement shown in dotted lines.
The lever 45 is pivotally suspended from the supporting rod 28 adjacent to one
of the arms 27, and at its lower end is provided with antifriction roll 46 rides upon
a cam or pattern surface 47 located on the reciprocating cross-feed 17, the action
of which cam communicates a constantly vibrating movement to said lever. The
roll. 46 is held in operative contact with the cam by means of a connecting
spring 48.
The backward throw of the guard plate from beneath the supported edge of the
sheet is so timed as to take place upon the return movement of the cross feed
after pushing the preceding sheet to the secondary scorers and after its forward
edge has moved back from beneath the edge of the sheet resting on the guard
plate, as shown in Fig. 9.
Upon such return movement of the cross feed, the cam surface 47 thereon
engaging with the lever 45 causes a positive backward throw of the same and
(in the event of connection being made between the parts) the connected guard
plate.
As the guard plate actuating lever 45 has a constantly vibrating movement, it
may happen that its groove 44 will not be opposite or in a position to receive
therein the end of the rod 30 when the latter is first acted upon in a longitudinal
direction by the passage of a sheet under the controller finger 35. For such
reason, the yielding connection between the finger and rod as described is provided.
In the event of the lever being in position with its groove forward of the end
of the rod as shown in Fig. 5, when a sheet passes under the finger 35 and moves
the same as described, the connected collar 38 is moved longitudinally on the

page_text: rod 36 and thereby compresses the spring 43 between the same and the adjacent
ring 41, causing it to act upon the latter and hold the end of the rod with a
yielding pressure against the adjacent face of the lever 45, whereby, when the
groove in the latter is brought to a position opposite the same, the end of the
rod will snap therein, as shown in Fig. 6. The bracket 34 with the supported
controller finger 35, and the several connections of the latter on the rod 36, are
adjustable back and forth on their respective supporting rods in order that they
may be adjusted in position according to the size of the sheets to be fed through
the machine, it being understood that the finger should be so located as to receive
the edge of the sheet, by which it is operated, thereunder.
In order to secure the quick return of the guard plate and connecting parts
to their normal operative position after the guard plate has been swung backward
from beneath a supported sheet, so as to be ready for the next sheet fed from the
primary scorers, I have pivotted a small elbow lever 49 upon one of the guard
plate carrying arms 27, as shown in Figs. 5, 6 and 7, one arm of which is
bifurcated and embraces the rod 36 to engage with a head or button 50 on the end
of the latter, while the other arm extends into a position to engage, upon the
backward swing of the guard plate, with a stationary arm 51 on the collar 30 so as
to cause the lever to swing on its fulcrum and thereby move the rod 36 longitu-
dinally to withdraw its end from the groove 44 in the lever 45 and so permit
the guard plate to swing back to its normal position. The said elbow lever 49
is operated as follows:-
When the guard plate is in its normal position, the several connecting parts
assume the positions indicated in Fig. 5, but when the rod 36 is moved longi-
tudinally by the passage of a sheet under the controller finger 35 and one end
thereof entered into the groove 44 in the lever 45, such movement of the rod causes
the head 50 at its opposite end to engage the elbow lever 49 to swing its free arm
into position to engage with the edge of the stationary arm 51, as shown in Fig. 6.
Now, as the guard plate is swung backward by the action of the lever 45, the said
free arm of the elbow lever, after the guard plate has been swung backward a
sufficient distance to permit the supported edge of the sheet to drop upon the
table is brought into contact with the arm 51 and operated thereby to move the
rod 36 longitudinally and withdraw its opposite end from the groove 44 in the
lever 45, as shown in Fig. 7, after which the parts again swing back to their
normal position shown in Fig. 5.
As the sheet is fed through the primary scorers, cach of its longitudinal edges
is trimmed by suitable trimming cutters, one of such cutters being one of the usual
laterally adjustable scoring knives, as shown in Fig. 4, which is set in proper
cutting relation to the bed roll 51, and the other formed by a rotary cutter disc 53
cooperating with the end of said bed roll 51, as shown in detail in
Fig. 10. The cutter disc 53, as shown, is mounted upon
which
a pin 54
is seated within a sleeve 55 having an adjustable screw
threaded connection with the supporting frame. By turning this sleeve back-
ward or forward in the frame, the position of the cutter disc may be adjusted
relative to the coacting edge of the bed roll to allow for any wear of the parts,
etcetera. Any suitable means, however, for supporting the cutter disc, other than
that shown and described, may be employed, or one of the usual scoring knives
be used in lieu of the same if so desired.
The leading edge of the sheet is guided and supported in passing from the
bed roll 5 of the primary scorers to the feed rolls 11, 11, upon a series of guide
plates or. devices 56 which have a sliding dovetailed connection with the forward
edge of the table 13 at a point between the said bed-roll and feed rolls, as
shown in Fig. 4. These plates are provided with tapering fingers the ends of
which lie in near relation to the upper surface of the bed roll so as to insure the
front edge of the sheets passing thereover. In order that the trimmed or severed
portions of the sheets, however, may be directed beneath the table immediately
after being operated upon by the cutters, and so be out of the way in the further

page_text: operation of the machine upon the main sheet, those guide plates adjacent to
the cutters are each formed with one of its fingers, indicated at 57, raised above
the surface of the bed roll and close to the outside of the cutters, so as to receive
thereunder the severed strips or pieces and direct the same below the table, as will
be clearly understood by reference to Fig. 4.
As a sheet is fed from the primary scorers onto the table 13, it passes over the
reciprocating cross feed which is operating at such time to push the preceding
sheet forward to the secondary scorers. In order, therefore, to prevent the sheet
being moved from its proper course by said cross feed and insure its being directed
and yieldingly held in position on the table to be properly engaged by the cross
feed after the guard plate has been swung backward from beneath its raised edge,
I have supported suitable downholds above the table which permit the free
movement of the cross feed and sheets thereunder, but bear with a yielding
pressure upon the sheet to prevent movement of the same other than that provided
for. The down holds, as shown, consist, of the brushes 5S which extend across
the table 13 in a direction at right angles to the feed rolls 11, 11 and are
suitably connected at their opposite ends with the cross rods 31 and 32 so as to
have a sliding adjustable connection therewith. Any suitable form of down
hold, however, for the purpose intended, other than that shown and described,
may be employed without departure from the invention.
It is of course understood that as the sheet is fed from the primary scorers, it
should be brought to a standstill upon the table 13 in position to be properly
presented to the secondary scorers when fed thereto by the cross feed. To accom-
plish this I have provided the lower feed roll 11 with a series of projecting pins 59
(only one of which is shown in the drawings) arranged in a straight row length-
wise of the roll, which are adapted to engage with the rear edge of the sheet
after being passed between the rolls and positively push the sheet forward upon
the table until the pins are carried below the plane of the latter. This ensures the
sheet being positively located in the proper position on the table, as the down-
holds bearing upon the sheet produce sufficient friction thereon to hold the same
from further movement after being released from the engagement of said pins.
The pins 59 are seated within openings in the feed roll and supported, by
means of a coiled spring 60 acting upon the same, with their ends yieldingly
projecting beyond the surface of the roll so as to yield when brought into
contact with the under side of a sheet passing between the two rolls without
causing damage thereto. As the rear edge of the sheet passes from between the
rolls, it then comes to an immediate stop, shown in Fig. 11, on account of the
friction produced by the downholds. In order, therefore, to insure the pins
positively engaging with the rear edge of the sheet after passing from between
the rolls, I have provided the upper feed roll with annular grooves 61 into which
the projecting ends of the pins enter when brought opposite the same so as to span
the space between the rolls and thus be caused to positively engage the rear edge
of the sheet, as shown in Fig. 11.
The sheet, after being so engaged by the said pins, is fed forward thereby to the
desired position upon the table, as indicated by dotted lines in said Figure 11.
Thereafter, the sheet is engaged by the cross-feed and fed to the secondary
scorers to be cut and scored thereby, said secondary scoring and cutting mechanism
being the same as that shown and described relative to the primary scoring and
cutting mechanism, with one of its end trimmers formed by a rotary cutter disc 62
co-acting with the end of the lower bed roll 6¹.
Referring to Figs. 12, 13 and 14, I have illustrated a device that may be
employed in connection with the brush downholds, or as a substitute therefor, in
acting upon the sheets to stop the same in a desired position upon the table 18
In accordance with this feature
after being passed through the primary scorers.
of my invention, the upper feed roll 11 is yieldingly in contact with the lower roll
by means of vertically movable spring pressed journal blocks acting downward
upon its end journals in the usual and ordinary manner.

page_text: One of these journal blocks, indicated at 63 in Fig. 12, is provided with a pin
or stud 64 upon which is pivotally mounted a lever 65, one end of which latter
is pivotally connected with a stationary pin or screw 66 upon the journal block
standard 67, and its opposite end or arm 68 extended out over the table 13 and
provided with a pivotally connected wheel or disc 681. This wheel or disc normally
rests upon the table 13 and is arranged to rotate in a direction at right angles
to the path of movement of the sheet in passing from the feed rolls upon said
table, as shown. As a sheet is passed between the feed rolls, the upper roll is
raised, thereby and in turn raises the journal block 63, which movement of the
latter operates the lever 65 to elevate its outer or free end and raise the supported
disc GS above the table, all as indicated by dotted lines in Fig. 12. The disc
is caused to remain thus elevated during the passage of the sheet between the
rolls and until the leading edge of the same has passed thereunder, after which
it is caused to drop upon the sheet at or before the time the latter has been fully
moved onto the table by the rear engaging pins 59 and cause the same to be
brought to a stand still in its proper position upon the table, the periphery of
the disc being milled or roughened to provide a frictional surface for engagement
with the sheet. When the sheet is moved forward by the cross feed to the
secondary scorers, the disc if not elevated above the sheet will rotate freely upon
the latter and not retard or interfere with its movement in such direction.
The means for controlling the drop of the disc 6S upon the sheet in proper
time, whereby the latter will be brought to a standstill in a desired position upon
the table, is as follows:-
A fixed arm or extension 70 of the standard 67 projects over the table 13 above
the lever 65 and is provided adjacent to its end with a vertically movable
plunger 71 fitted within an opening 72 therein, which plunger is connected with
the lever 65 through the medium of a pivotted link 73. Above the plunger 71
and with an air space or chamber 74 between their adjacent ends, is seated a
block 75, which latter is provided with a number of grooves 76 in its outer surface
communicating between the top of the opening 72 and the said air chamber 74.
Passing through the centre of the block 75 is a screw 77 which is provided with
a tapering slot or groove 78 formed in one side of the same. By means of such
described construction, when the lever 65 is raised by the passage of a sheet
between the feed rolls as indicated by dotted lines, the connected plunger 71
is moved upward and thereby forces the air from the chamber 4 out through
the openings in the block 75. Downward movement of the lever is then regulated
by the rapidity of the inflow of the air into said chamber as will be obvious, which
may be regulated by raising or lowering the screw 77 to expose more or less of its
tapering slot 78 above the block 75. A hinged cap 79 partially closes the upper
end of the opening 72 to prevent dirt or other foreign matter getting therein,
the same being provided with an opening 80 of greater size than the diameter
of the screw 77 to permit of the ready passage of the air therethrough.
Referring to Figs. 15-22 inclusive, I have illustrated a somewhat modified form
of construction embodying my invention whereby the guard plate may be actuated
to control the feed of the sheets by the passage of the latter through the machine.
In this instance the trip rod 36 and its controller 35 are dispensed with and
the action of the guard plate controlled from the upper vertically movable feed
roll 11. In accomplishing this, the vibrating lever 45 and the adjacent guard
plate supporting arm 27 are each provided with an extension 451 and 271 respec-
tively, the lever extension being provided with a sliding pin S1 seated therein
which may be moved to project one end in front of the lever arm 27¹ so
as to engage with and rock the latter on the rod 28 and thereby swing the
connected guard plate back from beneath the supported edge of a sheet, but which
pin is movably held by a spring 82 out of position for engaging with the guard
arm and with one end projecting beyond the side of the lever opposite said guard
arm, as indicated by dotted lines in Figs. 15, 17 and 22.
The pin 81 is operated to secure connection or disconnection between the guard

page_text: plate and its actuating lever 45, in a manner as follows;-An elbow lever S3
is pivotally mounted upon the rod 32 with one arm having an antifriction roll 84
resting upon the upper feed roll and yieldingly held against the same by means
of a spring 85, and its other arm having connection with one end of a pitman
rod 86, which latter at its opposite end has a yielding connection with the upper
end of a pivotted lever 87 which is supported adjacent to the actuating lever 45.
A latch device SS is pivotally connected at one end with the lever 87 and supported
with its free end normally resting upon the projecting rear end of the pin 81, as
shown. As a sheet is fed between the feed rolls, as indicated by dotted lines in
Fig. 15, the upper roll is thereby elevated and causes a backward movement of the
lever 87 through the medium of the several connections described, which move-
ment of said lever draws the end of the connected latch SS backward and from
its position resting on the pin 81, permitting the same to drop to a position
opposite the end of the latter as indicated in Fig. 20, so that after the sheet has
passed entirely through the feed rolls and the several parts (excepting the latch)
are returned to their normal position under the action of the spring 82, such
return movement of the lever 87 forces the latch against the pin 81 and causes
the opposite end of the latter to project into position to engage with the guard
plate arm 27 and so operate the latter to swing the guard plate from beneath the
supported edge of a sheet. After the guard plate has been moved backward
sufficiently to release the sheet, further movement of the same causes an arm 90
carried thereby to pass beneath the latch device and raise the same from engage-
ment with the pin, which latter then springs back to its normal position and so
permits the guard plate to return to its normal position. The pin engaging end
of the latch SS is formed in the arc of a circle to conform to the path of movement
of the pin as given by its carrying lever.
