Improvements in Paper Feeding Apparatus for Printing Presses,
and for Ruling, Calendering, and other Machines
We, WILLIAM AUSTIN PHILIOIT, Jr, of Niagara Falls, in the County of
Niagara and State of New York, United States of America, Manufacturer,
and THOMAS ARNOLD BRIGGS of Niagara Falls, South Ontario, Dominion of
Canada, Inventor, do hereby declare the nature of this invention to be as
follows
This invention relates to a paper feeding machine whereby sheet paper 19
automatically fed from a pile to a printing press, folding, ruling, calendering or
other machine in which sheet paper is operated upon
One object of our invention is to improve the construction and arrangement of
the feed tables so as to permit of conveniently renewing the supply of paper
without stopping the machine, another object of our invention is to provide a feed
mechanism which is simple in construction and reliable in operation and other
objects are to improve the machine in various other respects
According to our invention the main trame of the machine is provided with the
impression cylinder of a punting press having the usual grippers and the verti ally
movable registering guides arranged over the cylinder These guides are secured
to a transverse rod which is supported at its ends by lock arms
The main or
lower feed table is arranged with its delivery end over the impression cylinder, and
the supply table or upper feed table arranged at a suitable height above the lower
table The central portion of the supply table is supported on both sides by toggle
braces, each of which consists of an upper link which is pivoted with its upper end
to the fiame and a lower link which is pivoted with one end to the lower end of
the upper link and with its oppo ite end to the front portion of the adjacent
standard A stop aim is arranged on the upper link and is adapted to bear either
against a lug on the lower link, or against the underside of the supply table
the operative or depressed position of the supply table the lower links of the braces
est lengthwise upon the feed table while the stop arms of the upper links rest
upon the stop lugs and sustam the supply table As the supply table is moved
upon the pivot of the frame the links of the braces become straightened until the
stop arms bean against the underside of the supply table
In this inoperative
position of the supply table the pivotal connection of the links is located slightly
beyond the dead centie, to enable the braces to securely hold the supply table in an
elevated position by its own weight
In
Feed wheels are arranged between the front portions of the supply table and
the feed table, having their upper sides arranged in line with the top of the supply
table and their lower sides separated from the top of the feed table by a space
forming a throat for the passage of the body of sheet paper Ihese feed wheels
are secured to an intermittently rotating shaft journailed in beatings on the
standards
Two feed belts or tapes are provided passing with then receiving portions
around rollers journalled upon the rear portion of the table fi ime, thence forwardly
over the top of the supply table, thence downwardly around two of the feed

page_text: wheels, thence forwardly and upwardly over idler pulleys mounted on the supply
table frame, and thence forwardly to the place of beginning
The pile of sheets 18 placed upon the supply table and on the curying portions
of the feed tapes aud combed or tipped forwardly or with its top leaning toward
the printing piess, which cau-es the bottom of the pile to be arranged nearest the
feed wheel Upon turning the latter the bottom of the pile of sheets is carried
backwardly over the supply table, thence around the feed wheels and thence
forwardly over the feed table, whereby the position of the pile of sheets is
reversed and the bottom of the pile is arranged uppermost as it passes over the
feed table When the pile of sheets on the supply table has been reduced con-
siderably an additional quantity of paper can be placed thereon without stopping
the machine, because the feeding of the sheets takes lace from the underside of
the pile on the supply table
Au intermittent rotary motion is imparted to the shaft of the feed wheels by
auy suitable mechanism
This mechanism may comprise a ratchet lever mounted loosely on one end of a
shaft and provided with a pawl which engages with a ratchet wheel secured to
said shaft A rotary feed cam is provided engaging with the free end of the
atchet level and oscillating the latter The feed cam is secured to a diving shaft
near one end thereof and the latter is arranged transversely in front of the feed
wheels and joui nalled in bearings formed in the standards
A number of curved pressure arms serve to press the sheets against the outer or
front sides of the feed wheels for the purpose of increasing the grip of the latter
upon the sheets
These pressure arms are secured with their upper ends to a
tiansveise shaft which is jouinalled in bearings on the standards and are yieldingly
held against the shects by a weighted level connected with the said shaft
piessure arm is provided with a flexible metal band which extends downwardly
over its fi ce from its free end to the feed table, whereby the sheets are guidel as
they pass from the feed wheels to the feed table
Each
An upper guide is arranged lengthwise upon the supply table along one side of
the pile of sheets and capable of transverse adjustment on this table A transverse
rod is arranged underneath the supply table and secured to the table frame, and a
sleeve is mounted on said rod and capable of longitudinal adjustment thereon
This sleeve is provided with an aim projecting upwardly through a transverse
slot in the upper feed table and secured to the upper guide whereby the latter is
held in its adjusted position A lower guide is arranged lengthwise upon the feed
table along ule of the pile of sheets, and vertically in line with the upper guide
The upper and lower guides are adjustably conuicted by a connection con istine of
a tube pivoted to the sleeve and a rod pivoted to the lower guide and adju tably
secured with its mer end in the tub. by L 56 27 by ju tin, the length of
the conucation the position of the lower guide can be shifted back and for h on the
fced table to suit the pile of paper By connecting the upper and lower unles
they are always shifted together transverstly, thereby retamin, them in the proper
relative position at all times
Rotary brushing or combing wheels are arranged to bear with then lower
portions upon the sheets lying on the feed table ind which rot it in the prope
dnection to feed the sheets successively against the front registering Luide
These comb wheels have then faces provided with rolling bodies by which the
wheels bear upon the sheets in feeding the latter from the table The sud comb
wheels are secured to a transverse shaft and have their rolling bodies constructed
in the form of oval rollers having the axes arranged parallel with the axes of the
wheels The body of each comb wheel consists preferably of two dish-shaped
disks, the cential or web portions of which are secured to hub sections while their
eripheral portions are separated and form an annular groove between the margin
The combing ollis ir arranged in this love and journale to the
tlı 1 and project beyond the peripheries of the di Issoth teached bears upon
the paper with these roller-
of the disks

page_text: Upon rapidly rotating the combing wheels they roll with their combing rollers
over the pile of sheets which produces a rubbing action, whereby the sheets are
gradually combed or separated and the uppermost sheet is carried against the
front registering guides The action of the combing rollers is very gentle
and enables the finest paper to be operated upon without marring or injuring
the same
A longitudinal intermediate haft is arranged over the comb wheel shaft and
is provided at its frort end with a bevel gear wheel which meshes with another
bevel gear wheel secured to the diving shaft A spiral gear wheel mounted on
the longitudinal haft meshes with a similar piral gear wheel mounted on the
comb wheel shaft The lower spiral gear wheel is secured to the comb wheel
shaft but the upper spiral gear wheel is connected with the longitudinal shit by
a feather which compels the upper wheel to turn with its shaft but permits the
wheel to slide lengthwise thereon The bevel gear wheels are retunel in their
proper position by means of a yoke which is provided with a bearing in which the
driving shaft is journalled and by which the yoke is supported on the shaft and a
beating in which the front end of the longit idinal shaft is journalled
A supporting rod is arranged lengthwise over the longitudinal shaft and secured
at its front end to the yoke while its rear end is provided with a hanger in which
the rear end of the longitudinal shaft is journalled A sliding head is provided
whereby the spiral gear wheels are retained in their proper position and whereby
the comb wheels may be adjusted lengthwise on the lower feed table The lowe
portion of the head is provided on opposite sides of the lower spiral gear wheth
with two bearings in which the comb wheel shaft is journ illed, its cential portion
is provided with two bearings on opposite sides of the upper spial gear wheel in
which the longitudinal shaft is journalled and its upper portion is provided with a
split clamping sleeve which grasps the supporting rod Upon loosening the
clamping sleeve the head can be shifted upon the supporting rod and longitudinal
shaft for adjustin the comb wheels lengthwise of the feed table The comb
wheels rest upon the sheets with their own weight and that of the connecting
parts and are fiee to adjust themselves vertically to the variations in the thickness
of the pile of sheets owing to the pivotal connections between the voke and the
transveise ariving shait
The movement of the comb wheels is automatically controlled by mechanism
which is constructed as follows
-
A sleeve is mounted loosely on one end of the driving shaft and is capable of a
limited longitudinal movement thereon This sleeve is provided at one end with
a driving pulley which is connected with any suitable motor for imparting a
continuous rotary motion to the sleeve The opposite end of the sleeve is provided
with a conical head having an annular groove in its face which contains a coil of
insulated wire
Upon conducting a current of electricity through this coil the
conical head is converted into an electro magnet The ends of the coil are
connected with insulated commutato ings surrounding the rotary sleeve and the
current is conducted to the same by means of brushes bearing respectively against
the rings
A circular armature is secured to the diving shaft and provided with
a conical sochet which fits over the conical head Upon energizing the magnet
the latter attracts the armature, thereby coupling the driving pulley with the
driving shaft and setting the comb wheels in motion for feeding the top sheet of
the pile to the fi ont registering guides The instant the magnet is de-energized
the arinature is liberated, thereby arresting the movement of the driving shaft and
stopping the feeding action of the comb wheels An electric generator of iny
suitable construction is provided having one of its polcs connected with the
blush
A lower contact finger is secured to the rear end of the feed table but insulated
therefrom and is connected with the opposite pole of the electric generator
A transverse rock shaft is arranged and joura illed at its ends in bearings arranged

page_text: on the upper links of the braces A rock arm is provided secured to the cential
portion of a rock shaft and extending with its free end over a rod which suppor
the front registering guides An
upper contact finger is secured to the underside
of the rock arm and is adapted to hear against the lower contac finger
The upper
contact finger is connected with one of the brushes picferably by a wire connecting
with the metallic frame of the machine, whereby the frame is utilized as part of
the conductor for conducting the current to the upper contact finger, but, if
desired, this contact finger may be connected with the brush by an insulated wit
When the upper movable contact finger comes in contact with the lower fixed
finger the electric circuit is closed and the comb wheels are coupled with the
driving pulley by the electric clutch, which causes the comb wheels to rotate and
to 'eed a sheet forwardly to the front registering guides During the list portion
of the forward movement of the sheet toward the front registering guides it passes
between the contact fingers and separate. the latter I he sheet of paper being an
insulating medium breaks the circuit in passing between the contact fingers, thereby
uncoupling the clutch and airesting the movement of the comb wheels The comb
wheels rem un inactive during the entire time that the contact fingers are sepirated
After the sheet strikes the front registering guides the latter are raised to cleai
the sheet and the guppers of the impression cylinder grasp the sheet and carry it
off from the feed table During the upward movement of the front guides the rod
supporting the same engages with the free end of the 1ock arm and lifts the latter
together with the upper contact finger, so that the latter cannot touch the lower
contact finger and set he feeding mechanism in motion while the front guides arc
elevated After the sheet has been carried from the feed table the front guides
are again lowered into then operative position and the upper con act finger is agam
allowed to rest upon the lower finger for closing the cucuit and starting the
feeding of the next sheet
By arranging the front guides in such a relation with the upper contact finger
that the latter cannot touch the lower fingui until, the guides are in their operative
position the proper registering of each sheet is insured This also prevents the
upper finger from dropping through a hole which may be torn in a sheet and
thereby closing the circuit and starting to feed the next sheet before the preceding
sheet has been wholly cured from the pile
The comb wheels and the feed wheels are driven from the transverse driving
shaft which latter is intermittently rotated described and the intermittent rotary
movement of the food wheels i, thuicfore, synchronous with the intermittent
movement of the comb which

comb wheels is instantaneously stopped and the weight of the comb whitels and
connecting parts non resting on the next lower sheets holds the same firmly in
place and prevents displacement thereof while the top heet is being fed off
In order to prevent the arm of the upper contact finger from dropping while
raising the supply table, the 10ch shaft is provided near its ends with lugs cariying
spring catches which are adapted to engage with lugs on the upper links of the
