Improvements in Feeding Apparatus for Printing, Ruling, and
Folding Machines.
I EDWARD THOMAS CLEATHERO, of 16 Tollington Place N. in the County of
London Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for feeding sheets of paper successively from
a pile of paper into printing machines also into ruling folding and other machines,
where single sheets are required to be fed from the pile with certainty and
reliability of action, and which can be readily adjusted to any size and thickness
of paper.
According to my improvements the feed board is raised automatically with the
pile of paper, always keeping the top sheet to the same level untill the last sheet is
taken off the feed board, a bell is set to ring at a given moment to call the
attention of the machine minder, who by moving a handle attached to the feed
board, the feed board becomes disconnected and can be almost instantly lowered to
receive a fresh pile of paper, then by moving a lever the feed board is raised to
bring the top sheet to the required level. Ou releasing the handle of the feed
board the half screw-nuts which are fixed to slide at each side of the feed board
are pressed into the vertical screws by means of springs attached to the half
screw-nuts, these vertical screws are geared by means of bevel or worm wheel
gearing, the transverse shaft is geared down by spur wheel to a pinion fixed on
another shaft, which also has a ratchet wheel fixed on and a swinging arm carrying
a pawl. The swinging arm receives its motion from a disc or cam fixed on the
main shaft by means of a connecting rod, and is connected at one end to an
adjustable stud or pin fixed in a T shaped slot in the disc, the disc is divided into
a given number of spaced lines, each line is numbered, so that by moving the stud
or pin in the slot up to say spaced line numbered 8, the swinging arm with pawl
attached will move the ratchet wheel 8 teeth forward which is sufficient to raise
the feed board by one sheet of paper of a given thickness each revolution of the
printing machine. Paper being made in various thicknesses, a ream of paper say
2 inches thick requiring a movement of say 8 teeth forward of the ratchet-wheel,
a ream 5 in. thick would require say 16 teeth forward, this motion is got by setting
the stud on the disc to line numbered 16 which gives a greater throw to the
swinging arm with ratchet pawl attached, the ratchet wheel can also be moved by
hand in either direction for the purpose of adjusting the height of the feed board.
In order to remove the top sheet of paper from the pile I provide an improved
mechanical action for fluffing up the sides of the paper at the front edges which
is fixed to slide on two horizontal bars or other suitable means for carrying same
across the top of the front edge of the feed board, and which can be quickly
adjusted to both corners of the front edges of the paper to any size required to be
fed into the printing machine. For this purpose
provide a shaft carried in
bearings transversely above the pile of paper which is worked by a crank at one
end and has a long slotted keyway with bevel wheels or other suitable motion on
the shaft, this engages with a vertical shaft which is carried in the sliding frame
on the horizontal bars, and gives motion to another vertical shaft (which is carried
in the sliding frame work) in a circular direction, a bearing is fixed to the lower
end of this vertical shaft and carries a short shaft or spindle at right angles to the
vertical shaft at one end of this shaft or spindle is fixed a longitudinally
projecting finger bent down at the end with a piece of rubber attached, as the

page_text: horizontal shaft is moved in a circular direction when it comes towards the front
corner of the paper the finger is made to descend with its rubber end on to the
corner of the top sheet of paper and push the front part of the sheet backwards
causing the sheet to ruck up at the sides, when a foot which has also a circular
motion imparted to it passes between the top sheet and the pile of paper and
descends upon the pile holding the pile down until the top sheet is removed, after
this foot has descended on the pile the fluffing finger returns in a circular direction
and is lifted from the paper out of the way to allow the top sheet to be carried
forward the foot remaining on the pile of paper until another sheet is being
fluffed when it continues its circular motion and another foot which is on the
opposite side of the same vertical shaft passes round with its foot lifted until it
has passed under the next top sheet which is being fluffed, then it descends on the
pile of paper. The feet are pivoted to the lower end of a vertical shaft which
only travels in one direction half its circumference to each sheet of paper fluffed
and carried so that one foot is always being presented towards the top of the
pile of paper. The shaft carrying the feet also works in the saine frame as
the fluffing gear shaft but only in one direction by means of a cam and pawl
connected to a pinion wheel. In describing the fluffing arrangement, there are two
sets one at each front corner, also two carriers or more. In order to make a
greater certainty of fluffing only one sheet and also to regulate the size of the
fluff or arch of the paper caused by the fluffing finger I fix another transverse
shaft above the top of the paper some distance from the front edge which carry
projecting fingers towards the front edge of the paper these rest with their ends
on the paper to hold the edges of the paper down at the commencement of the
fluffing action and during the whole of the operation of fluffing, when they are
lifted off the paper by means of a rod attached to the shaft to allow the top sheet
to be carried forward on to a tape roll. For this purpose I provide two or more
rubber discs or feet fixed on to one end of projecting carriers, these descend with
their rubber faces downwards on the top sheet of paper and move in a forward
direction carrying the top sheet with them on to the tape rolls, when the carriers
are lifted off the paper. The carriers are connected at back end to swinging
arms, the swinging arms are mounted on a shaft and are moved to and fro by a
crank and rod and connected at the bottom to a lever which is lifted by a cam
fixed on the main shaft of the apparatus, the swinging arm has a rod or pawl
pivoted to it above the carrier at one end, the other end is made to press against a
peculiar shaped tooth formed on the carrier so that when the paper is carried
forward to the tape rolls this rod or pawl is forced against one of the shafts that
carries the fluffing gear and presses the carrier tooth backwards thus lifting the
carrier from the paper, it is then held in a raised position off the paper during
the return of the carriers by means of a over balanced pawl which falls into
position as the rod or pawl is pressed backwards, the over balanced pawl is lifted
out at the near end of the backward motion of the carrier to allow the carrier to
descend with its rubber face on the paper, for the purpose of pushing the top sheet
forward into the tape rolls, the paper is then carried on the tapes down a sloping
board to the front stops, when a rubber tooth descends on the paper and draws
the paper to the side stop, the tooth passes off the paper and leaves the paper in
a set position, when the sloping board is raised at the front edge by the action of
the printing machine, the front stops fall away and allows the paper to be taken
by the grippers of the machine cylinder. The side stop is carried on a shaft fixed
transversely across the sloping board and has a set screw to fix it in any required
position. Their is also another shaft in a parallel line with the one carrying the
side stop, this shaft slides longitudinally and has a boss with crank rod attached
and is connected to a crank on the side stop, on this crank rod a finger is fixed
with a rubber tooth at the end, this tooth having a circular motion descends on
the paper immediately the sheet of paper is carried to the front stops, the finger
is bent to the radius of the circle in front of the rubber and smoothes the edge of
the paper as the tooth descends on the paper, the shaft is carried in bearing

page_text: brackets fixed to the sloping board and is connected by a crank lever which
receives motion by means of connecting rods and levers from the main shaft by
means of a cam. The front stops are fixed on a shaft in the ordinary way, the
shaft is carried by bearings fixed to the front edge of board with slotted "holes
for adjustment and is held in position until the board has lifted when it falls
away, for this purpose I provide a toothed quadrant fixed on one end of the shaft
to gear into another toothed quadrant which is pivoted on the bearing and has a
projecting finger which is held in position by a pawl, when the board lifts the
pawl strikes against a pin and causes it to release its hold of the quadrant finger
and allows the side marks to fall away, when the board descends the quadrant
finger comes into contact with a stud on the under side and lifts the front marks
into position for receiving the paper, the pawl engages itself with the finger again.
The tape rolls are also geared to the main shaft of the apparatus which receives
its motion from the printing machine by means of bevel, chain or other suitable
gearing, a disc is fixed on this gear with a pawl attached, this pawl engages itself
to a one toothed ratchet wheel. To stop the apparatus I fix a crank on a pin to a
lug on the side of the apparatus or on a suitable bracket with a anti friction
pulley on one end the other end of the crank is connected to a lever or connecting
rod which engages with another rod, this rod is lifted by a handle on the side of
the apparatus and throws the crank pulley into contact with the pawl on the disc
and the pawl is lifted out of action with the ratchet wheel on the main shaft thus
stopping the feeding apparatus, the crank is also connected with the cylinder stop
so that the apparatus works at the same time as the cylinder of the printing
machine.

Improvements in Feeding Apparatus for Printing, Ruling, and
Folding Machines.
I, EDWARD THOMAS CLEATHERO, of 16 Tollington Place, London N.
Engineer, 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 has reference to the manner in which I construct and arrange
apparatus and mechanism for attaching to ordinary printing, ruling and folding
machines for the purpose of causing an automatic and regular delivery or feeding
of the paper which is to be operated upon.
In carrying my invention into effect 1 modify the method of driving my main
motion shaft to suit the particular type of machine or the gearing or shafting of the
machine to which my improvements are to be attached, and in the accompanying
eight sheets of explanatory drawings I illustrate my feeding apparatus when
attached to, and working upon an ordinary Wharfedale type of printing machine.
On Sheet 1, Figure 1 is a side elevation of the machine having the ordinary
portions of the printing machine shown somewhat in outline, the frames A being
extended or arranged to receive my improved appliances.
On Sheet 2, Figure 2 is a detailed side elevation of one of the side frames B,
and the mechanism attached or connected therewith which I secure to the ordinary
side frame of the printing machine B.
On Sheet 3, Figure 3 is a detailed end elevation of the side frames B and its
mechanism shown in side elevation at Figure 2.
On Sheet 4, Figure 4 is a detailed end elevation of a portion of my feeding
appliances showing the pile of papers P in position upon the table C.

with the clutch driving mechanism and the cable lowering and raising levers shown
in detail.
On Sheet 6, Figure 6 is an enlarged side elevation of the feeding mechanism
showing the fluffing arrangement, and Figure 6ª is a detail elevation of the feed
roller and its swinging arm.

(94 and 9B) are details of the side stops or edge marking mechanism, and Figure 10
is a detailed end elevation of the front stop lowering mechanism; Figure 11 is a
side elevation of the gearing for driving the table raising screws.
On Sheet 8, Figure 12 is a detailed side elevation of the audible indicator levers,
and the mechanism for stopping the feed motion by controlling the clutch.
Figure 13 is a side elevation showing an alternative method of operating the
sidestop fingers, also showing chain gearing for driving the tape roll.
The sheets or the pile of papers P, I place upon my feed board or feed table C, 1
which table I provide with an automatic rising motion for causing the top or
uppermost sheet of paper to be kept at a constant height for delivery to the
printing cylinder; and I also arrauge that the board C may be lowered and raised
very rapidly by hand for enabling a fresh pile of paper to be readily introduced on
to the board and for permitting that the adjustment or determination of the feeding a
level for the top sheet shall be effected by hand before setting the automatic
portion of my appliances in motion. I sometimes provide a bell or other alarm
for notifying to the attendant when the last sheet of paper is taken off the board.
I carry the feed table C from a cross shaft or stretcher bar D by means of
links D D which I anchor to boss brackets D' D'; and I provide a handle or
folding lever d, upon the boss D'³ for enabling the links D D to be raised or
lowered by hand when it is desired to alter the position of the board C, to which
the links are attached by means of side slide bars or guide plates C¹ formed upon
the table frame C². To the side frames B B₁ I mount or connect screws E, E'
having their teeth or screwed portions formed rack shaped as shown in Figure 4; :
these screws I set in motion at any desired speed by means of gearing f¹ƒ driven
from a pall and ratchet wheel which has its movement communicated by the
connecting rod f' anchored in a slotted cam f. The cam wheel f* I cause to
receive its motion from a pitch chain and wheel or by bevil or other gearing
suitably connected to any revolving portion of the machine. The stroke of the
connecting rod I alter to suit the thickness of paper sheet which forms the pile, so
as to ensure that the rise of the table shall only be that necessary to keep the level
of the top sheet of paper constant for delivery. I alter the stroke in one convenient
manner by making a graduated scale upon the jaw or slot in which the connecting
rod pin or block is carried, the graduations permitting of any desired thickness of
paper sheet being fed or raised by the table a height at each stroke of the
connecting rod equal to the actual thickness of sheet that is to be removed at each
operation of the machine from the pile upon the board. The ratchet wheel 1',
I form with any desired number of teeth to suit the ratio of gearing wheels
employed in connection with my feed motion shafts, and I cause the driving pall f
which I anchor to a rocking plate G, to engage with only one tooth at each
vibration, or to pass over any desired number of teeth in the wheel f' to suit the
thickness of paper sheet upon the pile P.
I communicate the motion of the screws E E' to half nuts F, F' which I connect
to the frame C, these nuts causing the table to rise when the screws E, E', rotate
within them. To disengage the nuts in order to permit of rapid alteration or
adjustment of the position of the board C, I connect levers f" to the nuts which
upon being pulled by hand allow of the weight of the table being carried by the
manipulating folding hand lever d, shown in Figure 4; for keeping the nuts in
position upon their screws when in work for feeding the paper, I place springs C
within and between the nuts and the frame C³. The ratchet wheel, can be
moved by hand in either direction for adjusting the height of the pile when the

page_text: movement produced by the hand levers d, j', as before described
great or insufficiently accurate.
Would DU LOO
I feed the sheet of paper in single sheets from the pile P by means of an
improved corner fluffing arrangement of mechanism and appliances, which I
employ, and which I illustrate in Figures 4, 5, 6 and 7. These front edge fluffers
raise up mechanically the two front side edges of the top sheet of paper in the
pile P, and by so raising these edges allow the holding down feet to be placed
underneath the top sheet which while permitting the top sheet to be drawn over
them also keep down the remaining sheet of paper correctly in position upon the
pile so as to prevent more than one sheet of paper being fed forward at a time.
I carry my fluffing appliances and apparatus preferably upon a pair of stretcher
bars or shafts H, H₁, running across from one side frame B to the other B¹. Upon
these bars H, Hi I mount a pair of sliding carriages H* H* so arranged that they
may be free to move along and be held at any position upon the bars to suit the
width of paper sheet forming the pile at any particular printing operation. From
one side frame B to the other B'I carry a shaft J within which I cut a long key
way or groove to enable bevil wheels or other gearing wheels J, J³ to slide
thereon, or I may make the shaft square or of other section than round for the
same driving and sliding purposes; I give motion to this shaft J by means of a
crank J at one end, and the motion of the shaft J is transmitted to the vertical
spindles K K', mounted upon the carriages H2 H3 by the bevil wheels J³ J³.
Upon the outer ends of the vertical spindles K, K' I mount segmental rack
wheel L, L', which gears into interrupted or specially formed tooth wheels L' L'
to give a vibratory movement to the spindles L³, L³, carried upon the same frame
or carriage H H³. To the face of the segmental rack wheel L L', I attach_a
connecting driving link L* which gives a vibratory motion to a vertical spindle L®
having a sleeve or bush L10 on the end which carries a horizontal bearing and its
spindle L"; upon this spindle L" I attach a bent fluffing finger L, and I secure
a piece of rubber or like material L upon the end of this bent finger piece or
arm L. As this horizontal shaft L" is moved in a circular direction I cause it to
descend upon reaching the front corner of the paper pile P, so that the rubber end
is pressed onto the top sheet of the pile; and I provide an adjustable spring or an
adjustable weight L in order that I may be enabled to vary the pressure to suit
different surfaces and thicknesses or quality of paper and as its circular motion
continues the edge or corner of the sheet is "rucked up" and this "rucking up
permits of a foot M, also having a circular motion imparted to it, to pass between
the top sheet and the remainder of the pile of paper, thus holding the pile down
until the top sheet is removed. I give the descending motion to the finger L
while it is being carried round by the link L8, by means of a striker L, and a
striking plate L". After the holding down foot M, has descended upon the pile
the fluffing finger L has its return circular motion imparted to it and is thereby
lifted from the surface of the loose or raised top sheet, thus permitting this
sheet to be carried forward to the printing cylinder; during the reverse move-
ment of the fluffing fingers the holding down feet on each side of the paper
remains upon the pile of paper until another sheet is being fluffed or "rucked
"when they continue their circular motion and other feet M' which are
upon the opposite side of the same vertical spindles L* pass round lifted, until
they have passed under the fluffed edge of the top sheet when they descend upon
and press down the remainder of the pile. I give this rising motion to the feet by
means of tail pieces m m' which I form upon their ends, these tail pieces working
within the box like end of the plate M³ which I secure to the carriage; within
this box I provide a cam like channel which has a recess at one side to permit of
the tails m, m' falling into it and thus allowing the feet M, M³, to descend and
to press upon the paper. The motion spindle L, is revolved by means of the
rack L' and the wheel L2; and this wheel L³, 1 form with a pall m² to give a
circular motion in one direction only to the ratchet m³ on the end of the spindle L.
I employ two sets of fluffing arms one at each corner of the front edge of the
up
"3

page_text: paper, the position of each being adjusted to suit the width of the sheets forming
the pile, and in order to further regulate and fluff the paper edges regularly and
uniformly, I mount another cross shaft N, within and between the side frames B B',
and upon this shaft N, I secure projecting fingers N' N' which hold the top sheet
of paper down upou the pile during the operation of fluffing, when this has been
concluded they are lifted off the paper by means of a rod N' worked from a
cam N, so as to permit of the top sheet being carried forward.
I carry forward my loosened or raised sheet from the pile by means of tapes and
a roll and rubber faced discs o working upon a spindle o' mounted by arms
upon a rod or spindle carried in bearings upon the frame, the sheet being removed
trom the pile by means of two or more rubber discs p, mounted upon one end of
projecting carriers P', which have a rising and falling motion imparted to them to
enable them to be raised from the surface of the paper on their backward or return
stroke, the rollers being arranged to revolve in one direction only and to be
bearing upon the surface of the paper during the forward movement of the
carriers P¹. I connect the carrier P, to a swinging arm P' which I mount
upon a cross shaft P³ and I give these arms their swinging to and fro movement
by means of a crank P and rod P which I connect at the lower end to a
cam operated lever P, the cam P' being fixed on the main motion shaft X. The
swinging rod I provide with a rod or pall P³, which I pivot to it above the
carrier P¹, at one end, the free end of this rod P8 I make with a peculiarly shaped
adjustable tooth P, so that when the paper is carried forward to the tape roll
this tooth P is forced against one of the shafts H¹ and by these being brought to
rest, while the arm or rod P is still moving forward the carrier P1 is raised by its
tail end, being thrust against by the end of the rod P until the holding out roller
upon the end of the pivoted arm PB presses forward the tail of the carrier thus
preventing its falling on to the surface of the paper again until the release tooth Pio
is brought into contact with the shaft H', on the return stroke or vibration of the
swinging arm.
The roller p carries the paper forward on to the tape roll O, from where it
passes on the tapes down a sloping board O' to the front stops, when a rubber
tooth O' descends on the paper and draws the paper to the side stops O³; the
tooth passes off the paper and leaves it in a set position; when the sloping board O'
may be raised when so arranged at the front edge by the ordinary action of the
printing machine the front stops fall away and allow the paper to be taken by the
grippers of the machine cylinder in the ordinary manner. The side stop O³, is
carried up a shaft Oʻ. fixed above the sloping board across the width of the
machine and has a set screw upon it to fix it in any required position. I mount
another shaft O' parallel with the shaft O' and I cause this shaft 0° to slide longi-
tudinally, and upon it I mount a boss 0° with a crank rod O' for giving motion to
a crank O on the side stop spindle O³, upon which spindle I secure the rubber
tooth O' and its arm 010. The rubber tooth having a circular motion descends on
the paper immediately the sheet is carried to the front stops, the finger being
bent to the radius of the circle in front of the rubber smooths the edge of
the paper as the tooth descends on to it. I arrange the rubber tooth O and
its arm O adjustable for varying the pressure or touch upon the paper, as
shewn in Figures 94 and 9 which illustrate a front and side elevation
of such an arrangement in which the rubber tooth is mounted in an arm 0¹¹
adjustable by a thumb screw 01 upon the arm 010, and having a spiral spring
interposed. I carry the shaft 0 in bearing brackets fixed to the sloping board O
(Figures 6 and 8) and it receives its motion from connecting rods and levers 013 014
actuated from a cam on the main shaft.
The front stops R, I fix on a shaft in the ordinary manner this shaft being
carried on bearings fixed to the front edge of the board and having
oblong holes within them for adjustment, these front stops I hold in position in
front of the board until the board has been lifted in the ordinary manner by
the machine, when I cause them to fall away by means of a toothed quadrant

page_text: wheel R' upon the stop shaft R', which gears in another similar quadrant R³,
which is pivoted upon the bearing and has a finger R' held in position by a
pall Rs.
When the board lifts, the pawl strikes against a pin R and causes it to release
its hold of the quadrant finger and allows the front stops to fall away. When
the board descends the quadrant finger comes into contact with a pin R', on
the underside and lifts the front marks into position for receiving the paper
when the pawl engages with the finger again.
The tape rolls are geared to, or driven from the main shaft of the apparatus
by bevil wheels chain or other suitable ordinary means. I fix a disc upon the
main shaft of the printing machine with an attached pall which engages with a
one toothed ratchet wheel for communicating motion to the feeding mechanism
(see Fig. 3). To stop the apparatus (as illustrated in Figures 2 and 3) I fix a
crank on a pin to a lug on the side of the apparatus or on to a suitable
bracket with an anti-friction pulley Z on one end of the crank while the other
end I connect to a lever or connecting rod Z' which engages with another hand
lever rod Z (Fig. 2). The hand lever rod Z is raised by a handle Zº (Fig. 2)
on the side of the apparatus and throws the crank pulley Z into contact
with the pawl Z on the disc Z2, and the pawl is lifted out of action with the ratchet
wheel on the main shaft, thus stopping the feeding apparatus; the crank is also
connected with the cylinder stops so that the apparatus works at the same time as
the cylinder of the printing machine.
I may vary the method of stopping and starting my apparatus, and I sometimes
employ a clutch S (Figures 5 & 12) on the shaft X for this purpose, this clutch
being formed with its jaws or teeth inclined so that upon being rotated in the back-
ward or wrong direction the feeding mechanism would stand still by the clutch being
worked out of contact with its driver S¹. I carry a rod S₁ from the sliding clutch S
so that the clutch may be thrown out of contact by hand upon the rod S³ being
pulled, and I also arrange the levers S so that the stopping of the machine cylinder
shall stop the feeding mechanism. Similarly I provide for the feeding mechanism
being stopped when the last sheet of paper has been taken from the pile by
mounting a lever S (Figure 12) with a cam like end upon it, which withdraws the
clutch operating levers when the table is raised to the position when no more papers
are upon it. When the supply of paper has almost been consumed and the table
is at a corresponding elevated position, I cause an alarm to be given either by means
of striking a gong or bell, or by making a contact with an electric bell bracket Y
(Fig. 4), this latter arrangement being preferable as it enables the alarm to be
given during the whole time that the board remains empty, or until the attendant
has lowered the table by hand for the introduction of a fresh supply.
I do not limit the application of my improvements as hereinbefore described
to any particular type of printing machine, but I modify the method and the
forin of mounting and arranging my fluffing levers and appliances, together with
the other improvements in the manner of feeding and gauging the paper, the
driving, stopping, starting and alarm arrangements of my apparatus as herein-
before described to suit any type or form of printing, ruling and folding machine
to which it is desired to apply my invention without departing from the essential
features of working as herein described and as illustrated in the accompanying
drawings.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be perforined, I declare that what I
claim is :-
1. In feeding apparatus for printing and the like machines, the use of an auto-
matically geared feeding table which is caused to rise by means of independent
screws working in semi-nuts or their equivalents carried upon the table, the
speed and extent of the rise at each revolution of the machine cylinder being

page_text: adjusted to suit the thickness of the sheet of paper upon the table substantially
as herein described.
2. The use in combination with operating screws and nuts for raising and
lowering the table referred to in the preceding claim of a quick release or nut
withdrawing arrangement of hand levers for permitting the table to be readily
raised or lowered by hand without setting the screws in motion substantially as
described and as illustrated in the accompanying drawings.
3. The combination and arrangement of feeding rollers p carried upon swinging
arms P having horns or adjustable stop teeth P P10 mounted upon the carriers P
for causing the rollers to be lifted off the surface of the paper and then to be
subsequently lowered again substantially as herein described and as illustrated in
the accompanying drawings.
4. The fluffing mechanism herein described with reference to Figures 4, 6, 6^, 7
wherein adjustable spring or weighted arms have a circular motion together with a
rising and falling motion to enable the feet M M' to press upon the surface of the
paper after the top sheet has been fluffed in the manner substantially as herein
described.
5. The combination and arrangement of feed mechanism herein described with
reference to Figures 3, 4, 5, for imparting the feeding motion to the feed rollers
from the main driving shaft X substantially as herein described and as illustrated.
6. In feeding apparatus as berein described the use of a graduated cam or
crank disc for varying the throw of the crank pin, in order that the driving
pall working upon the rachet may carry forward the desired number of teeth
to give a rise of the table proportional to the thickness of the sheet that is
withdrawn at each operation of the machine substantially as herein described.
7. The stopping and starting arrangement of the levers and clutches for permitting
the printing or like machine cylinder to revolve with or without the feeding
mechanism being in motion, and for enabling the feeding mechanism to be auto-
matically and independently controlled by the rise of the table to its extreme limit,
or by hand as desired without interfering with the ordinary driving motion of the
printing mechanism substantially as herein described and as illustrated.
8. In feeding apparatus as herein described, the combination of an alarm bell or
audible indicator which is automatically controlled and operated, upon the last
sheet of paper being withdrawn or upon a certain position being reached by the
rising table substantially as herein described and as illustrated in the accompanying
drawings.
9. In a feeding apparatus as herein described the combination and arrangement
of segmental racks R2, R³, levers R, and pins for lowering the front stops R
substantially as herein described and as illustrated in the accompanying drawings.
10. In a feeding apparatus as herein described the combination and arrange-
ment of a sliding side lay toothed finger adjustable upon a vibrating arm by
means of a thumb screw and interposed spring substantially as hereinbefore
described and as illustrated in the accompanying drawings.
