Improvements in and connected with Paper Feeding Machines for
Printing Presses and the like.
A communication from abroad by THOMAS A. BRIGGS, of Arlington, in the State
of Massachusetts, United States of America, Machinist.
I JOHN MAGRATH KELLY of 1 Charlotte Street Bedford Square in the
County of Middlesex Merchant 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:—
This invention relates to the class of paper feeding machines which pass the
sheets of paper automatically from a pile to the printing machine.
And it consists in an improved organization of a paper feeding machine

Similar letters of reference indicate corresponding parts. F represents the
rear end portion of the frame of a cylinder printing machine of which only the
impression cylinder C and feed-table C₁ are shown in Figures 1, 3 and 4 of
the drawing.
To the rear end of said machine is attached the frame of an improved
automatic paper-feeding machine, which latter frame embraces certain features of
novelty which constitute the subject matter of an application for Letters Patent

page_text: filed by me and of even date herewith. Said frame consists mainly of a base-
plate A, two pairs of posts A' A' A" A" rising from said base at opposite sides of
the machine, two heads A attached to the upper ends of said posts, and a cross
bar B extending across the machine and secured to the aforesaid heads at the
edges adjacent to the frame F. Across the machine extends a horizontal shaft a
which is journaled in suitable bearings on the aforesaid edges of the heads All
and to each end of said shaft is rigidly secured an arm D which is designated a
rock-arm inasmuch as it receives an oscillatory motion in the following manner.
To one end of the shaft a adjacent to the rock arm D is pivoted a supplemental
arm D', the free end of which has affixed to it a wrist pin D to which latter is
connected the pitman E which extends along the side of the frame F. and is
connected to a crank or wrist-pia on a wheel E¹ which receives rotary motion
from the driving shaft of the printing machine by means of suitable gearings,
which may be arranged in any suitable manner. For a mere exemplification of
said gearing same is represented in the form of the gear wheels, 1, 2, in Figs. 1
and 3 of the drawing.
Inasmuch as the driving gears of the printing machine vary somewhat in their
location, the pitman E is made adjustable in length and also in alignment so that
the automatic paper-feeding machine can be accommodated to such variations.
Said pitman is bent so as to bring the two end portions thereof out of line but
parallel with each other, and said end portions are screw-threaded in one and the
same direction and the connecting hooks or couplings bb which are provided with
screw-threaded sockets for the reception of said ends of the pitman are screw
threaded thereon. The screw threads of the two ends of the pitman running in
the same direction allows the pitman to be turned without changing the distance
between the two connecting hooks bb and by turning the pitman the lineal position
of said hooks in relation to each other is changed to accommodate them to the
position of the wrist pins.
In order to allow the said pitman to be retained in its adjusted position the
connecting hooks bb are split longitudinally at the ends by which they are
connected to the pitman, and the divided portions of each of said hooks is
provided with coinciding transverse bolt-holes, one of which is screw-threaded,
and a bolt passing through said holes clamps the split portion of the connecting
hook b on the pitman E as best seen in Figs. 21 and 22 of the drawing.
To facilitate the operation of connecting and disconnecting the pitman to and
from the wrist-pins the connecting hook is provided with a longitudinal
channel 6 extending from the hook-end nearly to the opposite end, and in said
channel is inserted a spiral spring 11 and a slide-bolt c which latter is thus
backed by said spring and is forced outward by the same. A thumb-piece c¹
passes through a longitudinal slot in the underside of the connecting hook and is
screwed into a socket in the underside of the bolt c, said slot permitting sufficient
longitudinal movement of the bolt to allow the same to enter with its outer end
into a socket or an eye in the hook-portion of the connecting-hook and also
allow the bolt to be retracted so as to clear the entrance in the connecting hook
and thus allow the same to be hooked onto the wrist-pin.
The spring automatically forces the bolt c out and across the wrist-pin and
thus retains thereon the connecting hook b. The two connecting hooks 66 on
opposite ends of the pitman can be readily adjusted to the proper distance apart
to correspond to the distance between the wrist-pins, by turning one or both of
the connecting hooks, in which operation the screw connection of the latter with
the pitman causes the connecting hook to move longitudinally on the pitman.
The supplemental arm D¹ is locked on the rock-arm D by means of a bolt d
passing transversely and loosely through the rock-arm and entering a socket & in
the inner or adjacent side of the supplemental arm, into which socket it is forced
by a spring d as shown in Fig. 6 of the drawing. On the rock-arm D is a
boss Dill against which the supplemental arm rests when in position to be locked
by the bolt d, said boss relieves the bolt from strain sufficiently to allow the same

page_text: o be readily withdrawn from the supplemental arm when desired to release the
ock-arm from its locked connection with the supplemental arm and thereby arrest
the motion of the rock-arm.
To effect this automatically across the frame A is extended a rod e mounted
revolubly in suitable bearings on the frame, and to one end of said rod is rigidly
attached a came which can be thrown across the inner protruding end of the
bolt & where it engages the outer side of a lug or pin el projecting from the side
of the bolt as shown in Figs. and 7 of the drawing. Said cam is beveled so as
to press on the pin e' with gradually increasing force during the rocking motion of
To retain the cam
the arm D and thereby withdraw the bolt from said arm.
either in or out of the aforesaid position as may be desired there is attached to
the opposite end of the rod e a weighted crank which rests in an inclined
position against the frame A when set to carry the came into its operative
position in relation to the pin ell of the bolt d and when the weighted crank is
turned to throw the cam out of its said position said crank is in a pendent position,
hence the crank is retained in its aforesaid two positions automatically by
gravity.
To opposite sides of the frame are attached longitudinal guide-rods f on which
are mounted the slides 99 which are connected to the free ends of the rock-
arms DD by pitmen E" E
In order to increase the length of the movement of the slides og over the
stroke of the rock-arms, there is employed in connection with the rock-arms the
following mechanism for transmitting motion to the pitmen.
h
To each side of the frame is firmly attached a segmental beveled gear / Figs. 6
and 26 concentric to the rock shaft a and on the rock-arm D is journaled a
shaft extending lengthwise of the rock-arm and having secured to opposite ends
beveled pinions "one of which engages the segmental gear has shown. The
pinion on the opinion on the opposite end or outer end of the shaft h¹ meshes with
a similar pinion i fixed to a short shaft i journaled transversely to the free end of
the rock-arm. To this shaft is firmly secured an arm E the opposite end of
which is pivotally connected to the pitman E".
The details of the rock-arm D and mechanisms connected thereto are more
fully described in another application for Letters Patent of even date herewith
and in which it constitutes the subject matter claimed therein.
In the oscillations of the two rock-arms D the shaft is rotated alternately in
opposite directions by the engagement of the inner pinion h" with the stationary
segmental gear h and a corresponding motion is transmitted to the transverse
shaft by the engagement of its pinion i with the pinion on the outer end of
the shaft and the motion of said transverse shaft an oscillatory movement is
imparted to the arm E of greater speed and stroke than that of the rock-arm,
and consequently the length of the stroke of the pitman is likewise increased to
carry the slide the entire length of the feed-table C₁ of the printing machine.
99 and
Transversely over the said feed-table is a shaft j journaled to the slides
to said shaft are fastened the grippers GG the construction and attachment of
which is shown in detail in Figs. 10 and 11 of the drawings, and consists of the
hook G formed with perforated ears G' G' on its rear end by which it is hung on
the shaft and from said ears project shoulders G" G" which abut against the
edges of a concave bar H disposed parallel with the shaft j and rigidly attached to
the slides gg.
The hooks gg are thus sustained rigidly in their position.
I
On the underside of the body of the hook G is a tongue H' formed at its rear
end with an eye H" by which it is hung on the shaft between the ears G¹ G¹.
Radially through the said eye passes a set screw H₁ which engages the shaft and
thereby fastens thereto the tongue H¹.
To one end of the shaft j is fastened a crank j¹ and to the side of the slide g is
pivoted a finger ", one end of which is provided with a longitudinal slot by
which it is pivotally connected to a trunnion on the free end of the crank as
shown in Fig. 5 of the drawing. A suitable spring k holds the finger in an inclined

page_text: position and causes it to press upward the free end of the crank j¹ and turn the
shaft j so as to hold the grippers G G with their free ends in proximity to the
feed-table C¹ as shown in Fig. 10 of the drawing. The finger is formed with
a downwardly and upwardly extending cam which downward cam comes in
contact with a stop as the grippers G G arrive at the end of their forward
movement and by this contact the finger is caused to depress the rear end of
the crank and thereby turn the shaft j so as to lift the free ends of the
tongues H¹ H¹ of the grippers G G and thus opens the grippers and liberate the
paper drawn forward by the grippers to deliver the paper to the usual and well
known grippers on the impression cylinder C of the printing machine.
The stop is of the form of an L shaped latch pivoted at its angle to a
block mounted on the guide rod f. The horizontal limb of the stop is
weighted and normally rests on a shoulder projecting from the block as
shown in Fig. 1 of the drawing. The stop is allowed to tilt rearward and leave
the tripping finger ¹¹ undisturbed while the same is drawn back on the stop.
Back of the rear end of the feed-table C¹ is another tripper hung on the
frame-head Awhich tripper is allowed to swing forward but restrained from
swinging rearward by a suitable stop on the frame as best seen in Fig. 5 of the
drawing, which shows said tripper in its operation. As the slides g are drawn to
the rear end of the feed-table C¹ the finger with its upward cam j passes
under and to the rear of the tripper and is thereby depressed and immediately
released to allow the grippers G to take hold of the front edge of the paper
passed to the grippers by the pushers hereinafter described. As the slides g move
forward the-tripper being free to swing in said direction leaves the grippers in
their closed condition to draw the paper forward over the feed-table C.
Above the plane of the feed-table C¹ and back of the rear end thereof is a
transverse shaft m pivoted at its ends to the heads A" of the supporting frame of
the automatic paper-feeding machine. On said shaft are hung the paper feeding
pushers consisting of arms J firmly secured thereto in a pendent position, and
fingers Jhinged to said arms so as to be sustained with their lower end inclined
toward the rear end of the feed-table C' to the free ends of which fingers are
fastened the rubber or other suitable friction blocks J as best seen in Figs. 8
and 9 of the drawing.
It is preferred to form the said friction blocks cylindrical but they are fitted
tightly in the bifurcated end of the finger J' which are provided with angular
spurs entering opposite sides of the block J" as clearly shown in Fig. 9 of the
drawing. The block is thus prevented from accidentally turning and yet allows it
to be turned by hand when desired to bring a new surface thereof in contact with
the paper.
To facilitate the attachment and detachment of the arm J to and from the
shaft m and also allow said arm to be shifted longitudinally on said shaft to
accommodate the paper pusher to the width of the paper to be fed to the printing
machine, the said shaft is provided with a longitudinal groove m¹ and the upper
end of the arm J is formed with a hook J by which it is hung on the shaft as
shown in Fig. 8 of the drawing. The pendent portion of the arm J is provided
with a longitudinal channel n in which is a sliding bolt n' which has a screw-
threaded hole transversely through it, and in said hole is inserted a thumb-screw n
which projects through a longitudinal slot in the side of the arm. The interior of
the channel n is formed with a recess 14 in such a position that when the bolt n
has entered the groove m¹ of the shaft m, the thumb-screw can be turned so as to
cause its inner end to enter the recess 14 and thus securely lock the bolt. In the
bottom of the longitudinal channel n is a spiral spring n which forces the bolt
upward and in engagement with the groove ml. The upper end of the arm J is
formed with a forward projection J which has a vertical perforation through
which passes freely a rod K attached to the finger J. On said rod is a disc K
which has a perforation of such a size as to allow the rod to slide freely through it
when the disc rests horizontally on the projection J as illustrated in Fig. 8 of the

page_text: drawing, but by tilting the said disc it becomes bound on the rod. To cach_end
portion of the shaft m is fastened a bell-crank L, Fig. 6, one end of which is
connected by a pitman L' to the lower end of a lever M' fixed to the rock-shaft a to
which the rock-arm D is attached, and thus an oscillatory motion is transmitted to
the bell-crank L and shaft m.
To the upper end of the lever M' is adjustably connected a set-screw M" which
by contact with the frame as shown in Fig. 7 of the drawing serves as a stop by
which to adjust the said lever to its requisite position on the rock-shaft.
o represents a metallic plate which extends across the machine and projects from
the front side of a shaft pivoted to the upper ends of the two bell-cranks L on
opposite sides of the machine. To one end of said shaft is secured a forwardly
extending arm o¹ to the free end of which is pivoted a roller ol for the purpose
hereinafter explained. From the side of said arm projects a lug ol of sufficient
length to strike the top of the frame A when the free end of the arm is deprived
of its support as hereinafter described.
p' is a cam pivoted to the frame-head A and formed with a pendent arm p" by
the gravity of which the said cam is sustained in its normal position and when in
said position the roller o" of the arm o' rides upon the cam p¹.
The oscillation of the bell-crank L rocks the shaft m which causes the arms J J
of the paper-pushers to oscillate back and forth over the paper piled on the
supporting table M. Said paper abutting with the front edges of the sheets against
vertical plates p p hereinafter more fully described.
Simultaneously with the oscillations of the aforesaid paper-pushers, the plate o is
moved back and forth and pushed under the discs K by the upper arms of the
bell-cranks L, said plate moving rearward as the paper-pushers move forward.
In the forward movement of the plate the roller o rides upon the top of
the camp until it drops from the front end of the cam. This dropping is
arrested by the lug on on the arm o¹ striking the top of the frame Al
from which projects an inclined cam o'. In the rearward movement of the
plate o the roller o passes under the cam and to the rear end thereof, and in this
latter movement the lug o is drawn upon the inclined cam o which lifts the
arm o¹ and causes the roller o¹¹ to pry up the rear end of the cam until the roller has
passed said end, when the cam is thrown back to its normal position by gravity of
the pendent arm p" of said cam. The plate then moving forward again, causes the
roller to travel on top of the cam and thereby further lift the front edge of the
plate o which is under the rear portions of the discs K' K. Said discs are thus
lifted and at the same time tilted so as to become bound on and lift with it the
rods K which are attached to the paper-pushing fingers J. Said fingers are
thereby lifted off from the paper during the rearward movement of the fingers.
To the rear portion of the plate o and axially parallel therewith is pivoted a shaft
to which is attached a plate p, the front portion of which extends over one or
more of the rods K and to said shaft is also firmly secured a lever g g which reaches
over the front edge of the plate o and is connected by a rod r to a lever r¹ pivoted
to the lower arm of the bell-crank L as shown in Fig. 7 of the drawing. Said
plate p is designated the regulating plate inasmuch as it regulates the action of the
mechanisms which automatically raise the paper supporting table M as hereinafter
described. In the path of the free end of the lever is a crank s which projects
horizontally from the upper end of a vertical shaft s journaled in bearings secured
to the frame-head A as best seen in Fig. 12 of the drawing, and from the lower
end of said vertical shaft extends outward another crank-art s. From the side
of the frame-head A projects horizontally a stud-pin t on which is loosely
mounted a bevel-pinion t which has rigidly attached to it or integral with it a
ratchet-wheel and a hub between them, on which hub is loosely mounted a
hangen to the lower end of which is connected the pawl adapted to engage
the aforesaid ratchet-wheel. On the rock-shaft a adjacent to the supplemental
rock-arm D is loosely mounted a crank N the free end of which is connected to
the lower end of the hanger " by a rod N¹ and to this rod is connected the lower

page_text: crank-arms". The adjacent faces of the hubs of the supplemental rock-arm D'
and crank N are formed with projections N" which extend about one-fourth the
distance around the eyes by which said arm and crank are hung on the rock-shaft.
Said projections are shown in detail in Figs. 23, 24 and 25 of the drawing. The
two projections "allow the crank N to be moved by the supplemental rock-
arm D' when said crank is set into a position to cause the rear face of its projection
to come in contact with the projection of the rock-arm D during the latter part of
its rearward movement as indicated by dotted lines in Fig. 5 of the drawing. The
crank N being thereby swung forward and caused to draw the pawl in the
same direction. The engagement of said pawl with the ratchet wheel t" imparts a
partial rotation to the pinion t
The crank N is set into its aforesaid operative position by the regulating plate p
in the following manner :-
In the operation of passing the sheets of paper successively from the pile on the
supporting-table M to the feed-table C' by the oscillatory push-fingers J, the latter
obviously drops after the passage of each sheet a distance equal to the thickness of
the sheet last past. The regulating plate p riding on the rod K which is attached
to the finger J' causes said plate to turn downward to a corresponding degree, and
after a number of sheets have been passed from the pile, the position of the finger J
carries the rod K so low as to allow the plate p to drop sufficiently to cause the
lever gg to throw the lever against the upper cranks of the vertical shaft s'.
Said shaft is thereby turned and caused to push the rod N¹ rearward by the lower
crank-arms. This movement of the said rod sets the crank N in a position to be
actuated by the supplemental rock-arm D' as hereinbefore described, and at the
same time the pawl is set into a position to engage the ratchet wheel t¹ which
is thus turned and caused to turn with it the pinion . This pinion meshes with a
similar pinion u attached to the upper end of a vertical shaft u¹ journaled in
bearings respectively on the frame-head A and base-plate A. On this vertical
shaft is a worm-gear " which is adapted to slide vertically on the shaft and is
locked thereon to rotate with the shaft either by a spline on one entering a groove
in the other or by an angular form of the shaft and correspondingly shaped eye in
the gear, or by other well known means. The groove is indicated by the heavy
black lines 13, in Fig. 1 of the drawing. The worm-gear " meshes with worm-
wheels secured to shafts which extend horizontally across the machine
and are journaled to the brackets OO on which the paper supporting table M is
mounted, said brackets being provided with vertical sleeves by which they slide in
the posts A A. To the shafts u are also fastened the pinions vv which engage
vertical racks on opposite sides of the posts A¹ A¹. It will thus be observed
that the paper-supporting table M is raised at intervals of time by the turning of
the pinion which imparts a corresponding motion to the shaft u¹ the worm-
gear of which transmits motion to the shafts u ul by the worm
wheels u and the rotation of the latter shafts causes the pinions vv thereof
to run upward on the racks ov¹ and thereby raise the table M to bring the top of
the pile of papers up to the proper plane to allow the paper to pass to the feed-
table C' as indicated by dotted line 15 in Fig. 7 of the drawing.
To allow the table M to be raised or lowered by hand when required, a crank w
is employed provided with an eye w' by which to slip it onto the end of the stud-
pin t and an annular head w¹ of a greater diameter than the ratchet-wheel t¹¹ so
as to cover the outer sides of the teeth of said wheel. The pawl t is wider than
the wheel so as to allow the edge of the crank-head wll to bear on the pawl and
hold it out of contact with the ratchet wheel. (See Figs. 13 and 14 of the
drawing.)
In order to automatically stop the table-raising mechanism when all the paper
has been fed from the table and the latter raised to the plane of the feed, to the
crank s is pivoted a guard-plate 1 which lies across the end of the upper crank s
and has its free end sustained by a pin 2, passing through a slot 3, in the plate and
secured to the frame. (See Fig. 7 of the drawing.)

page_text: 5
The slot 3 is of sufficient length to allow the plate to be pushed up by the
table M coming in contact with the bottom edge of the plate and when thus lifted
the plate projects above the cranks and thereby prevents the lever r¹ from striking
the pin secured to the free end of the crank.
PP represent stays against which the sheets of paper abut with their front
edges and are thus held evenly thereat. These stays consist of vertical plates
sustained laterally adjustable so as to accommodate them to different widths of
paper to be fed. Said plates rest with their lower ends against the rear side of a
vertical flange P¹ on the base-plate A as shown in Fig. 4 of the drawing. The
upper ends of the stays are adjustably sustained on a cross-bar P secured to
frame-heads A which cross-bar is formed with a T-shape groove Pl, as shown in
Fig. 7, extending lengthwise of the bars. To each of the stays P P is attached a
plate Qprovided with a T-shaped head Q which is inserted into the groove Pil
In order to allow the plate Q to accommodate itself to any unevenness in the
alignment of the groove P the attachment of said plate is made slightly yielding
by passing the attaching bolt loosely through the plate and its head and through a
spring Q and upset the ends of the bolt. The plate is thus held on the stay P by
the pressure of the said spring. The plate is provided with vertical flanges by
which it embraces the side edges of the stay and thus relieves the bolt from
lateral strain in the operation of shifting the stay laterally on the cross-bar P₁ to
adjust the stay to the width of the paper lying on the table M.
To the top portion of the frame heads A is firmly secured a cross-bar R, the
side of which is formed with a rack extending lengthwise thereof, and a similar
rack-bar R parallel with the bar R is secured to posts attached to the base A as
shown in Fig. 2 of the drawing.
To the two cross-bars R R are movably connected two vertical bars R" R" by
means of sleeves R R on the ends of the vertical bars loosely embracing the
cross-bars. On the vertical bars are journaled the vertical shafts S S to which are
rigidly attached the pinions RR which engage the racks of the cross-bars.
By means of cranks S¹ attached to the vertical shafts they can be turned when
desired, to shift the vertical bars and shafts laterally, which movement is effected
by the engagement of the pinion R with the racks of the cross-bars. Said
adjustment is required to hold the paper evenly piled between the vertical
bars R R". Said adjustment also brings over the paper the separating mechanism
hereinafter described.
From the upper portion of each of the vertical bars R extends rigidly rear-
ward a horizontal arm T which is concaved on its inner side and has in said side
a shaft extending lengthwise thereof and journaled in bearings on the ends of the
arm (Fig. 15). To the front end of said shaft is fastened a beveled pinion which
meshes with a beveled segmental gear all, fastened to the rock shaft m to which
the paper pushers J are attached. The shaft & thus receives a rocking motion from
the shaft m.
x
On the shaft is mounted a longitudinally movable bracket y which is formed on
one side with perforated ears through which the shaft passes, and on the opposite
side with a vertical guide y' and vertically perforated ears y. Between the first named
ears of the bracket is a worm-gear y"" and a clutch-collar y. The said gear is free
to rotate on the shaft and the clutch collar is provided with a spline which engages
a longitudinal groove in the shaft as shown in Fig. 19 of the drawing, and thus the
clutch collar is forced to turn with the shaft. The side of the worm-gear y¹¹ has
rigidly projecting from it two spurs which are beveled on one side and squared on
the opposite side. In the adjacent end of the clutch-collar y is a longitudinal
channel in which is a bolt backed by a spiral spring" which forces said bolt
outward and in position to engage one of the spurs during the rocking motion of
the clutch-collar, as illustrated in Fig. 17 of the drawing.
In the vertical guide y' on the opposite side of the bracket slides a rod U, and in
the ears yy is journaled a worm-gear U¹ through the centre of which passes
freely the vertical shaft V which is provided with a longitudinal groove in which

page_text: slides a feather attached to the interior of the gear U₁. To the top of the upper
ear y is fastened an upward projecting cam-ring V₁ concentric to the shaft, and on
said shaft is hung a collar from which projects a finger V" which lies across the
cam-ring V. Said collar is made to rotate with the shaft by a lug on the interior
of the collar entering the longitudinal groove of the shaft.
Above
To the two ends of the rod U are rigidly attached cross-bars W W formed with
vertical sleeves W W in which the ends of the shaft V are journaled.
the lower cross-bar is a duplex cam 4 rigidly secured to the shaft V and extending
horizontally in opposite directions therefrom. To the lower end of said shaft
beneath the lower cross-bar W is fastened transversely at its centre a foot W, to
the top of the end portions of which are secured rubber faces W or other suitable
frictional bearings.
To the rod U above the cross-bar W is swiveled a lever X which is held in
contact with the cam 4 by means of a spring X' attached to the cross-bar and to a
downwardly extending finger on the said lever. On the hub of the lever X is a
transverse sleeve 5 in which is held revolubly the arm 6, the free end of which is
bent to rest upon the top of the pile of paper on the table M and has rigidly
attached to it a rubber block 11 and is made to constantly bear on the paper by
means of a coil spring surrounding the arm and fastened thereto at one end to the
sleeve 5 at the opposite end. To the cross-bar W is pivoted a spring finger 7
which extends forward over the top of the foot W" and bears with its free end on
top of the pile of paper. The opposite end of said finger has a lever 7" extending
from it and under the duplex cam 4. The described devices are set into a position
to operate over the rear corner portion of the pile of paper. The adjustment to
said position is effected by shifting the vertical bars R R on the cross-bars R R¹
lengthwise of the latter so as to bring the inner edges of the vertical bars against
opposite sides of the pile of paper, and thus keep the same even, then the
brackets y y are moved lengthwise on the shafts a to carry the devices connected
to the brackets over the rear portion of the pile of paper.
To securely retain the vertical bars R R in their adjusted position the upper
journal-boxes 8, 8, are split longitudinally and provided with perforated ears 9, 9,
one of each pair of which is screw-threaded. By means of clamping-screws 10,
10, inserted in said ears the journal-boxes are pinched onto the shafts. This
fastening of the vertical shafts is very essential inasmuch as the paper must be
maintained evenly piled on the table M and this depends on the position of the
vertical bars R¹¹ R¹¹.
In the operation of the machine, the shafts ax turn alternately in opposite
directions and make a half revolution in each turn. In turning in one direction
the spring-bolt in the clutch-collar y which turns with the shaft, engages
the spur and consequently turus the worm-gear y¹. In the reverse movement
of the shaft a the aforesaid spring bolt slides over the beveled side of the
spur and thus leaves the worm-gear undisturbed. Hence the said gear is
turned intermittently in one direction, and the worm-gear U with the shaft V
is turned correspondingly. In each turn of this latter shaft one of the arms of
the duplex cam 4 pushes back the lever X and thereby turns the arm 6 suffi-
ciently to carry the free end of said arm 6 forward upon the pile of paper. As
the shaft V turns, one end of the foot W" is swung off from the top of the
paper and simultaneously lifted by the lug V" riding on the cam-ring V₁. The
duplex cam 4 is lifted with the shaft V and as the cam turns it presses on the
lever 7 and thereby causes the finger 7 to bear on the paper with increased
pressure. At the same time the arm 6 moves forward and causes the paper to
buckle as represented at 12 in Fig. 15 of the drawing, and while the paper is in
this condition, the other end of the foot is carried under the buckled portion of
the paper, and in this manner the top sheet is separated from the underlying
sheet. The rod U and shaft V slides freely vertically on the bracket and by
their gravity they hold the arm 6 with its friction block in constant contact with
the paper. The movements of the paper-feeding mechanism are so timed that the

page_text: paper-pushers J J' will push the paper forward as soon as the top sheet has been
separated from the subjacent sheet as before described. The paper being drawn
across the rubber face W and being pressed thereon by the spring-finger 7 in
If there should be
front, and by the rubber block 11 of the arm 6 at the rear.
accidentally two sheets of paper buckled and riding over the rubber face of the
foot W the said rubber face will retain the lower of the said two sheets while
the upper sheet is drawn forward. Thus only a single sheet can be fed at a
time.
During the said operation of the separating mechanism the paper-pushers J JI
are raised and swung rearward, and by the time the top sheet has been separated
from the subjacent sheet, the aforesaid pushers are brought to bear on the paper
and moved forward and thereby push the top sheet to the feed-table C' where the
sheet is taken by the grippers G G.
