PROVISIONAL SPECIFICATION.
Improvements in Automatic Apparatus for Feeding Letter-press,
Lithographic Printing Machines, Folding, Ruling, Calendering,
Label Making and other Machines of a like nature with Paper
or other Material.
I EDGAR ARNOLD PALLISTER of 2 Wade Street Wade Lane Leeds in the
County of York, Printers' Engineer do hereby declare the nature of this invention
to be as follows:-
My invention refers to improvements in the details of automatic apparatus for
feeding letter press, lithographic printing machines, folding, ruling, calendering,
label making and other machines of a like nature, with paper or other material;
and is hereunder described with reference to the improved apparatus or attachment
the subject of Letters Patent No. 6238 of 1890.
My invention comprises :-
1° An improved clutch lifting arrangement for raising the vertical side rods or
bars carrying the holding down bar. This consists of a bracket, which is herein-
after for the sake of distinction referred to as the "clutch bracket," fitted on each
of the vertical side rods, and which when the gripping tongue of the clutch is held
out of operation, is capable of sliding over the vertical rod. The clutch bracket is
formed with two projecting lugs, in which is fitted a pin which latter serves as a
hinge or fulcrum for the above mentioned gripping tongue. The gripping tongue,
which is hinged to this pin, is arranged so that its free end when raised bites or
grips against the vertical side rod. The vertical side rods may be round or
rectangular in section, but are preferably made round. To prevent any slipping
or undue play the free end of the tongue piece is hollowed out, so as to more or
less accurately fit and embrace that side of the vertical side rod against which it
bears. The underside of the gripping tongue towards its free end is connected by
a pin joint to the upper end of a link, the lower end of the latter being connected
to the end of a lifting lever operated by suitable intermediate mechanism from
Home convenient moving part of the printing or other machine.
2° An arrangement for keeping the carrying tapes (from the feed apparatus to
the printing cylinder) tight at all times, whatever may be the position of the
feeding rollers (as they are raised and lowered by the vertical side rods) over
which they pass. This consists in mounting the tape shaft (next the printing
cylinder) in bearings formed in the free ends of a pair of levers, (one at each side
of the machine). These levers are hinged to the side frames and kept pressed
towards the printing cylinder by springs. These springs yield, when owing to the
vertical movement of the feed rollers, the latter tend to move away from the
cylinder end tape shaft; and when the tendency is in the opposite direction, they
press the levers and the tape shaft carried by them towards the printing cylinder.

page_text: 3° An improved arrangement of mechanism for driving the carrying tapes
intermittently in one direction only. This consists in prolonging the table rack
(for moving the impression cylinder), where this may be necessary, and gearing it
directly or by means of an intermediate wheel or wheels with a toothed wheel
mo inted loosely on one end of the tape shaft (next the printing cylinder). Such
loosely mounted tooth wheel is provided on one face with clutch teeth, which face
is kept pressed against the corresponding face of a clutch collar fixed to the tape
shaft. The teeth of the clutch wheel and collar are so shaped, that the clutch
acts only in one direction.
1
4° A "fence arrangement attached to the holding down bar for setting the
front edge of the pile of paper to. This consists of a plate capable of sliding
vertically in guides attached to or formed at about the middle of the holding down
bar. The fence plate is balanced by a weight, both the plate and the balance
weight being connected by means of a hinged bell crank lever, which is hinged or
pivotted on a stud fixed to the holding down bar. When the holding down bar is
raised, the fence can be depressed in the guides, and then serves as a stop to set the
front edge of the pile of paper to.
5° An arrangement for lifting up the holding down bar and the rake or
separating rollers, so that a fresh supply or pile of paper can be laid and set on
the feeding table without any necessity for actuating the printing machine or
moving round the main shaft of the same, until the holding down bar is thereby
moved into its highest position. This consists in providing a cross shaft below the
vertical sliding bars before mentioned, and fitting cams on the same so as to bear
against the lower ends of the said vertical sliding bars, thereby raising or lowering
them (and the holding down bar and sheet separating mechanism carried by them),
according as the cam shaft is rotated in one direction or the other. The cam shaft
is provided at one or both ends with a handle for actuating the cam shaft by hand.
6° In order to prevent the topmost sheet from straightening out in a backward
direction after it has been bent or curved up for the purpose of separating it from
the rest of the pile, I provide an adjustable upright capable of being moved up
against the back edge of the pile, and having loosely fitted thereon a sliding weight.
This sliding weight rests upon the topmost sheet of the pile until the same has
been drawn from under the weight, and afterwards prevents the topmost sheet
straightening out in a backward direction.
70 In order to bring the impression cylinder immediately to a standstill when
the detector stop arrangement (referred to in the above mentioned Specification
No. 6238 of 1890) comes into operation, I provide an auxiliary arrangement
which is automatically put into operation from some convenient part of the detector
stop arrangement. This auxiliary arrangement may consist of a lever keyed on
the release lever shaft (see Specification No. 6238 of 1890), which by the move-
ment of the latter operates the cam or cam lever (used for holding the cylinder
brake out of action), so that the cam is moved on one side allowing the cylinder
brake instantly to come into action and to lock the impression cylinder. The
above auxiliary arrangement will of course require modification to suit the
particular type of printing machine to which the feeding mechanism is applied.
Dated this 11th day of April 1891.

Improvements in Automatic Apparatus for Feeding Letter-press.
Lithographic Printing Machines, Folding. Ruling, Calendering,
Label Making and other Machines of a like nature with Paper
or other Material.
I, EDGAR ARNOLD PALLISTER of 2 Wade Street. Wade Lane, Leeds in the
County of York Printers' 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:-
My invention refers to improvements in the details of automatic apparatus for
feeding letterpress, lithographic, printing machines, folding, ruling, calendering.
label making and other machines of a like nature, with paper or other material, and
is hereunder described with reference to the improved apparatus or attachment the
subject of Letters Patent No. 6238 of 1890, but I wish it to be distinctly under-
stood that my invention is more or less applicable to other types of feeding
apparatus.
My invention comprises
1° An improved clutch lifting arrangement for raising the vertical side rods or
bars carrying the holding down bar. This consists of a bracket, which is herein-
after for the sake of distinction referred to as the clutch bracket," fitted on each
side of the vertical side rods, and which when the gripping tongue of the clutch is
held out of operation, is capable of sliding over the vertical rod. The clutch
bracket is formed with one or two projecting lugs, in which is fitted a pin, which
serves as a hinge or fulcrum for the above mentioned gripping tongue.
The
gripping tongue which is hinged to this pin, is arranged so that its free end when
raised bites or grips against the vertical side rod. The vertical side rods may be
round or rectangular in section, but are preferably made round. To prevent any
slipping or undue play, the free end of the tongue piece is hollowed out, so as to
more or less accurately fit and embrace that side of the vertical side rod against
which it bears. The under side of the gripping tongue towards its free end is
connected by a pin joint to the upper end of a link, the lower end of the latter
being connected to the end of a lifting lever, operated by suitable intermediate
mechanism from some convenient moving part of the printing or other machine.
Instead of attaching the lifting link as above described, between the fulcrum and
the vertical side rod, I may place the fulcrum between the lifting link and the
vertical side rod. This lifting clutch arrangement is applicable for raising and
lowering the side rods, whether the holding down bar is placed at the front or
back or between the front and back on the pile of paper.
20 An arrangement for keeping the carrying tapes (from the feed apparatus to
the impression cylinder) tight at all times whatever may be the position of the
feeding rollers, (as they are raised and lowered by the vertical side rods), over
which they pass.
This consists in mounting the tape shaft next the impression
cylinder in bearings formed in the free ends of a pair of levers, one at each side of
the machine. These levers are hinged to the side frames, and kept pressed towards
the impression cylinder by springs. These springs yield, when owing to the vertical
movement of the feed rollers, the latter tend to move away from the cylinder end
tape shaft; and when the tendency is in the opposite direction, they press the levers,
and the tape shaft carried by them, towards the impression cylinder.
3° An improved arrangement of mechanism for driving the carrying tapes
intermittently in one direction only. This consists in prolonging the table rack,
(for moving the impression cylinder), where this may be necessary, and gearing it
directly or by means of an intermediate wheel or wheels with a toothed wheel
mounted loosely on one end of the tape shaft (next the impression cylinder). Such
loosely mounted tooth wheel is provided on one face with clutch teeth, which face

page_text: In the
is kept pressed against the corresponding face of a clutch collar fixed to the tape
shaft. The teeth of the clutch wheel and collar are so shaped, that the clutch acts
only in one direction, that is in the direction to cause the tapes to feed.
case of overfed machines the above mechanism is actuated from the spur wheel of
the impression cylinder, instead of from the rack.
4° A "fence arrangement attached to the holding down bar for setting the
front edge of the pile of paper to. This consists of a plate capable of sliding
vertically in guides attached to or formed at about the middle of the holding down
bar. The fence plate is balanced by a weight, both the plate and the balance
weight being connected by means of a hinged bell crank lever, which is hinged or
pivotted on a stud fixed to the holding down bar. When the holding down bar is
raised, the fence can be depressed in the guides, and then serves as a stop to set
the front edge of the pile of paper to.
5° An arrangement for lifting up the holding down bar, and the rake or separating
rollers, so that a fresh supply or pile of paper can be laid and set on the feeding
table, without any necessity for actuating the printing machine, or moving round
the main shaft of the same until the holding down bar is thereby moved into its
highest position. This consists in providing a cross shaft below the vertical sliding
bars before mentioned, and fitting cams on the same so as to bear against the lower
ends of the said vertical sliding bars, thereby raising or lowering them, (and the
holding down bar and sheet separating mechanism carried by them), according as
the cam shaft is rotated in one direction or the other. The cam shaft is provided
at one or both ends with a handle for actuating the cam shaft by hand.
6° In order to bring the impression cylinder immediately to a standstill when
the detector stop arrangement, (referred to in Specification of Letters l'atent
No. 6238 of 1890), comes into operation, I provide an auxiliary arrangement which
is automatically put into operation from some convenient part of the detector stop
arrangement. This consists of a lever keyed on the release lever shaft, (see above
mentioned Specification), which by the movement of the latter, operates the cam or
cam lever (used for holding the cylinder break out of action), so that the cam is
moved on one side allowing the cylinder brake instantly to come into action, and to
lock the impression cylinder. The connections of the above auxiliary arrangement
to the cylinder brake will of course require modification to suit the particular type
of printing or other machine to which the feeding mechanism is applied.
In the present Specification the term printing machine is to be understood to
stand also for other machines referred to in the title of the Specification.
And in order that my invention and the manner in which the same is to be
performed may be more readily and clearly understood, reference is given to the
accompanying drawings; which illustrate my invention as applied to one type of
printing machine.
Fig. 1 is a general perspective view.
Fig. 2 is a partial perspective view, shewing the lifting clutch arrangement.
Fig. 3 is an elevation, showing the alternative arrangement of the clutch tongue
or tongue lever.
Fig. 4 is an elevation, and Fig. 5 a plan shewing the tape tightening and tape
driving arrangements.
Fig. 6 is a partial perspective view shewing the front (holding down bar) fence.
In all the figures the same reference letters refer to the same or corresponding
part.
a are the vertical side rods carrying the holding down bar and attacluments.
is the clutch bracket, is the gripping tongue (or tongue lever in Fig. 3), e is
the filerum of the same. are the lifting links, operated from some convenient
moving part of the printing machine through shaft hand levers i keyed thereon.
When the lifting link is in its lowest position, the gripping edge of the tongue is
just clear of the edge of the vertical side rod; but the upward movement of the
link tends to bring the tongue into a position at right angles to the vertical side
rod, and so to shorten the distance of the tongue edge from, and to cause it to bite

page_text: against and raise the vertical side rod as the upward motion of the lifting link is
continued.
are the carrying tapes, and the tape shaft next the impression cylinder /.
in is one of the hinged lever- carrying one of the journals of the rape shaft at it fr
mi. a is a flat or other pring which presses the lever i towards the impression
cylinder and tends to keep the tapes tight, but which spring yields when the
other tape shaft o is raised by the vertical side rods, thereby slightly increasing
the direct distance between the raised centre of the tape shaft o and the original
position of the tape shaft A.
p is the continuation of the table rack, which gears with an intermediate toothel
wheel, y, and the latter gears with the toothed wheel loosely mounted on the tape
shaft A. The toothed wheel is provided with a clutch face on one side which
faces towards the clutch face of a sliding clutch s, also mounted on the tape shaft,
but which can move longitudinally along this shaft over a fixed key or feather.
The sliding clutch is pressed towards the gear clutch wheel r by means of the
spiral spring t. The teeth of both clutches are so shaped and the pressure of the
spring so regulated, that the tape shaft is only driven in one direction as above
described.
"
s
is the fence plate fitting in slides formed in the holding down bar b. v is a
bell crank lever, pivotted on a stud w fixed to the holding down bar b. One arm
of the lever is slotted and through the slot passes a stud, attached to the fence
plate v. A weight, attached to the other arm of the lever r, keeps the fence
plate u raised when the feeder is in operation; but by throwing over the lever r
in the direction indicated by the arrow, when the holding down bar bis raised, the
fence plate is depressed and serves as a stop against which to set the front edge
of the pile of paper.
yy are cams fitted on the cross shaft z, and arranged directly beneath the lower
ends of the vertical slide rods a a. When the shaft is rotated by means of a
handle in the direction indicated by the arrow, the vertical sliding rods a a and
the attachments thereto, are raised so that a fresh supply of paper can be laid or
set on the feeding table 3 without any necessity for actuating the printing machine
for that purpose. 22 are tongues of suitable material such as india rubber with which
the feed rollers are provided, as shown in Figure 1.
4 (Figs. 1 and 7) is the lever keyed on the release lever shaft o, Fig. 7, (same
as horizontal shaft o in the Specification No. 6238 of 1890). When the shaft o
moves, raising the lever 4, this latter catches against the cam shaped end of the
lever 5, and turns it into a horizontal position (as indicated in Fig. 7) rotating the
shaft 6 and with it the cam 7, allowing the lever 8 and rod 9 to be drawn down by
a spring at the lower end of the latter. The rod 9 is connected with the mechanism
allowing the impression cylinder brake to come into action.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed declare that what I
claim is :-
In feeding apparatus for printing and other machines above referred to :--
1° In combination with the vertical side rods or bars and the holding down bar curried
