page_text: Attachments. therefor.
I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex
Engineer, do hereby declare the nature of this invention for "IMPROVEMENTS IN
PRINTING MACHINES AND NUMBERING ATTACHMENTS THEREFORE" (a communication
from John Robert Carter of the Village of Niagara Falls, in the state of New
York, United States of America, Manufacturer) and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:-
:-
The principal object of the invention is to devise mechanisin by which numerals
or other signs may be imprinted on paper on either one or both sides during the
passage of the web or sheet of paper through the printing machine and it consists
essentially in providing Wheels having the numerals or other signs embossed or
engraved on their periphery and locating the said Wheels above and below the
passage way through which the Web or sheet of paper passes and so operating the
said Wheels in connection with suitable platens that the numerals or other signs
opposite to the platens will be constantly and regularly changing while the platens
with equal regularity will force the paper against the printing wheel referred to
and furthermore in providing suitable gear by which the speed of the apparatus
for numbering feeding and cutting may be increased the whole being arranged and
operated substantially as hereinafter more fully explained.

In the Drawings like letters of reference indicate corresponding parts in each
figure.
In describing this invention I will first refer to figs from 1 to 8 in which the
mechanism for numbering operates at the saine speed proportionately as the main
driving shaft of the Machine from which it derives its inotion.
The Web or sheet of paper after having received its impression from the plate on
the reciprocating press is conveyed by suitable mechanisin between the upper and
lower wheels marked A and B respectively on the periphery of which wheels the
numerals or other signs to be printed on the paper are embossed or otherwise
formed.
The wheels A are keyed or otherwise fastened to the shaft C while the, wheels B
are keyed or otherwise fastened to the lower shaft D Both these shafts are
clearly seen in fig. 1a where it is shown they are geared together by the spur-
wheels E and F the spur wheel E being keyed to the upper shaft C while the
spur wheel F is keyed to the lower shaft D-On this lower shaft the arm G is
journalled and is connected to the spur wheel F by a dog H which dog is shown
clearly in Fig. 5 and is so formed that the arm G may be drawn in one direction
without acting on the wheel F while the movement of the arm in the opposite
direction would cause the said wheel F. to move in proportion to the distance of
the travel of the said arm.
I, is a rod arranged to connect the arm G to some revolving part of the machine
so that when the machine is in operation the arm G shall have imparted to it a
rocking movement and through the dog H the spur wheels E and F derive a rotary
motion in proportion to the stroke of the arm and consequently the printing
wheels A & B inay be turned on their axes any given distance by merely adjusting
the stroke of the arm G, for instance the rod I is shown in figure 1° connected to
the arm G, by the wrist pin g. This wrist-pin g may be adjustable in a longi-
tudinal slot made in the arm G or more than one wrist pin may be provided as
suggested in this figure,, where an additional wrist pin is shown closer to the
centre of the shaft D.
As the rod I, is connected at its other end to the revolving crank J. the stroke of
the arm G will be less when it is on the pin g than when it is placed on the wrist
pin h consequently the printing wheels A & B. will revolve a greater distance for
each stroke of the armi G when the rod I is connected to the said arm by the wrist
pinh than it does when connected to the wrist pin g.
It may here be mentioned that the machine is so set that each stroke of the
arm G. moves the printing wheels A and B. a distance represented by the space

page_text: between the numerals or other signs on their periphery & the object of providing
means for increasing or decreasing the revolving motion of the said wheels is to
enable more or less figures being arranged round the periphery of the wheels with-
out altering their diameter for instance if one hundred numbers are required to be
printed, each revolution of the wheels A and B, the numbers on the said wheels,
will be closer together than if only fifty numbers were arranged round a wheel of
the same diameter. In order to ensure that each and every stroke of the arm G
shall move the wheels A and B. exactly the same distance on the arm G is placed
a spring plate K which presses against the face of the spur wheel F so as to form a
frictional connection between the arm G and the spur wheel F. sufficiently strong
to enable the motion of the arm on its return stroke to carry with it the wheels E
& F. sufficiently far to take up any lost motion and bring one of the teeth in the
spur wheel F against the end of the dog or pawl L, the rest of the mechanisın
being arranged as I shall describe further on so that the paper shall not be brought
in contact with the numbers on the wheels A & B until the wheel F is at rest with
one of its teeth jammed against the end of the pawl or dog L, consequently each
stroke of the arm G, moves the wheels A, and B, the exact given distance required.
34 and 35 are spur pinions engaging with the spur-wheels E and F. These
spur pinions are keyed to the spindles of the distributing rollers R which supply
the ink to the numbering wheels A and B.
In order to bring the paper against the wheels A and B, I provide a platen M,
for each wheel the paper being carried between the wheel and its particular platen,
the platens for the upper wheels A being fixed to the lower shaft N. while platens
for the lower wheels B are fixed to the upper shaft O.-Both the wheels A and B,
and the platens M. are adjustable on their respective shafts so that the printing
wheels A and B may be adjusted to bring the numbers at any desired point on the
paper and the respective platen for each Wheel may be adjusted to bring it in its
exact position for its particular wheel-The shafts N. and O. are suitably journalled
in the frame of the machine at such a point that when rocked they will bring the
ends of the platens M. against the peripherys of their respective wheels A and B.
at the exact moment that the said wheels are at rest and the number to be printed
on the paper in the exact required position.
Nothing peculiar is claimed in the main mechanism for. imparting the rocking
motion to the shafts N. and O. but something is claimed in the peculiar inanner of
transmitting the motion of one shaft to the other and of adjusting the said shaft so
as to alter the pressure of the plattens against their respective wheels.
On reference to figure 2 it will be noticed that the lower shaft N. is provided
with an arm P. and that a rod 2 is connected to the said arın This rod 2 is
connected to some moving part of the machine so that when the machine is in
motion a rocking movement shall be imparted to the arm P. which is conveyed to
the lower shaft N. and to the upper shaft O the latter being connected to the
shaft N. by the boss p. and toothed collar q. the toothed boss p. being part of the
arm P while the toothed collar q. is loose on the upper shaft O. but has a lug on it
which projects between the jaws r. formed on the bracket R. which is keyed to the
upper shaft O.
8 are set screws screwed into the jaws r. so as to provide means for adjusting the
connection between the lower shaft, N. and the upper shaft O. the bracket R. being
keyed to the upper shaft, O. while the toothed collar q. which is loose on the upper
shaft O. meshes with the toothed boss p. secured to the lower shaft N. consequently
the motion of the lower shaft, N. is conveyed to the upper shaft O. through
the lug, t, which extends between the jaws r. and is adjusted between them by the
movement of the set screws, 8. consequently by adjusting the set screws the
platens M. on the upper shaft O. may be arranged to come with greater or less
force as desired against their respective wheels.
In order to adjust the platens on the lower shaft N the rod q. is connected on
the arm p. by jam nut u, the adjustment of which on the end of the said rod q.

page_text: 5
will alter the pressure of the platen on the shaft N. against their respective
wheels.
Mechanism for imparting the necessary rocking movement to the arin P. through
the arm q. is not shown as nothing peculiar is claimed in it, it being merely
necessary to say that the end of the rod q. which is not seen in Fig. 2 is connected
to a crank or eccentric which imparts to it a regular reciprocating motion calculated
to impart the necessary recking movement to the arm P. It should be also
mentioned that the platens are each provided with a set screw v. so that they may
be readily adjusted longitudinally upon their respective shafts in order as before
stated to bring them into the exact positions required.
In order to provide means for inking the periphery of the printing wheels, A.
and B. inking rollers R. and S. are placed in such a position that they come against
the peripherys of the wheels A. and B. respectively each roller being provided with
an ink distributor T. which derives a longitudinal reciprocating motion from the
arm u one arm being provided for each distributor and being operated by the
cams, V. as shown in Fig. 3.
In the drawing numerals printed on the peripheries of the wheels A. and B.
using simply marks to indicate them the features of course being to have any
numeral or mark which will print on paper when the latter is pressed against the
wheel-On the face of the spur-wheel F. I have printed a number of numerals
which are intended to represent and correspond with the marks or numerals
printed on the wheels A. and B. the numerals on the wheel F. being so arranged
that when one comes opposite to the dog L. a figure corresponding with it on the
wheels, A. or B. or both is in position to imprint itself on the paper forced against
it by the plattens consequently the numbers on the spur-wheel, F. when brought
opposite to the dog L. indicates the particular number set in position to print-As
before stated the spur-wheel F. is keyed to the shaft D while the arm G. which
connects it through the dog H. to the main mechanisin of the machine is loose upon
the said shaft.-It follows therefore that the shaft D. when turned by a handle
placed on its end will convey motion to the wheels A. and B. and the mechanism
immediately connected with them without conveying any motion to the rest of the
machine consequently the ink rollers may be reinked and the ink well distributed
over them without running the entire machine and after this has been accomplished
the proper number to be printed may be brought into position by simply bringing
the number required indicated on the wheel F opposite to the dog L.
Having now specified the apparatus shown in figures from 1 to 8 1 will now
describe the manner in which the speed of the numbering cutting and feeding
mechanism may be doubled by the manipulation of the gearing deriving its motion
from the main driving shaft of the press in connection with an alternative form of
device for feeding the ink onto the distributing roller beginning with the main
driving shaft of the press.
On the main shaft D of the machine is keyed a spur pinion which meshes with
the gear wheels 2 on the shafts 5 which gears with the minor gear wheel 3 on the
shaft 4. Tho teeth in the wheel 3 are half in number to those on the wheel 2 so
that the speed of the shaft 4 and all its connections will be double the speed of
the printing press proper as the press derives its motion from connecting rods 6
eccentrically pivoted on the disc 2 and 7.
As the web 8 runs through the press at double the reciprocating speed of the press
as hereinafter explained two blocks of type must be set up in order to provide for
the increase.
On reference to Figure 2 it will be seen that the rack 9 is eccentrically pivoted
on the shaft 4 which imparts a reciprocating motion to the rack 9. This rack 9
engages with a pinion 10 loose on the shaft 13.and is connected by a pawl 11 to
the ratchet 12 which is keyed to the feed roll 13; consequently as the rack moves
_up it causes the feed roll 13 to revolve by the connection of the pawl 11 to the

page_text: ratchet 12 and as it moves down it draws the pawl over the teeth of the ratchet ·
without affecting the feed roll as shown in detail in Figure 14.
Above the feed roll 13 a spindle is journalled having wheels 14 on it to keep tho
web of paper securely on the roll and prevent it slipping.
Other spindles are connected by their respective pinions to the pinion (see
Figure 1) formed on the feed roll so as to perforate the paper if required but as
nothing is claimed in them a description of their operation is unnecessary.
In Figures 2 and 9 I show the method of connecting the boss p and toothed collar q
which operate the platens M on the shaft N and O respectively is shown. In these
figures it will be seen that the rod 16 is pivotally connected at its upper end to an
arın 17 formed on the boss p and at its lower end is eccentrically pivoted to the
shaft 4. The connection thus formed gives the double notion required for the
platens.
On the outer end of the shaft 4 an eccentric 32 is pivoted being connected by the
rod 19 to the bell crank 20 which in its turn is connected to the bell crank 21 by
the rod 22. These bell cranks 20 and 21 are pivoted respectively on the shafts 23
and 24. On the upper inner arm of the bell crank 20 is pivoted the dog 25 which
engages with the ratchet 26 keyed on the shaft 23 while on the lower crank the dog
or pawl 25 and ratchet pinion 20 are placed on the outer side. It will now be
understood as the rod 19 moves down by the action of the eccentric 32 the pawls 25
move the ratchets one tooth and as the rod moves up it draws the pawls over the
ratchets to the next tooth.
27 are ink fountains supported at the rear end by the rod 31 passing through
them. The shafts 23 and 24 pass through the fountains and have inking rollers 28
keyed on them inside the walls of the fountains 27. The lower front end of the
fountains 27 are open so as to allow the inking rollers 28 to project through slightly
to give the necessary supply of ink from the fountain 27 to the distributing rollers R.
This supply is gradual being affected to a nicety by the action of the pawls 25 and
ratchets 26 as herein before described and the spring plate 29 kept loosely against
the periphery of the set screw 30.
In Figure 11 is exhibited my device for operating the platens when the speed is
increased by means of the rod 33 eccentrically pivoted to the shaft 4 from which
the increased speed mechanism derive their motion. As the operation of these spur
wheels and pinions is before described in referring to the ordinary speed of the
numbering apparatus it will not be necessary to again refer to them.
In Figure 12 I show the mode of operation of my device for the cutting of the
paper. As the shaft 4 revolves it brings the cams 36 and 37 successively in
operation by the action of the friction rollers 38 and 39 respectively pivoted on the
arm 40 which has a slot formed in it to permit of the vertical movement of the said.
arm as exhibited in Figure 13. The upper end of this arm is pivoted to a crank 41
keyed to the square shaft 42 on the other side of which is keyed another crank 43.
This crank 43 is pivotally connected at 44 and 46 by the forked rod 45 to the bell
crank 47 pivoted at 48 on the frame. The other arm 49 of the bell crank 47 is
pivoted at 50 at one end of the bar 57 and at the other at 53 on the arm 54 pivoted
5 at 55 on the frame.
52 is the upper knife, and 56, is the lower knife, forming as it were a pair of
shears through which the paper passes and is cut into sheets.
Having now described the specific form of this cutting device its operation will
be easily understood. As the friction roller 38 is thrown up by the operation of
0 the cam 36, the arın 40 is correspondingly thrown up by reason of its crank
connections with the arm 40.
When by the operation of the cam 37 the friction roller 39, and arm 40, is thrown
down, and the knife correspondingly for the same reason as before stated, thus per-
forming the action of cutting the paper. The paper after being cut is delivered by
5 endless tapes into the delivery box, suitable rollers being arranged as shown in
Figures 1 and 2 to drive the tapes, by gear connection to the counter shaft situated

page_text: at the front of the delivery box, a pulley, 57, being keyed on the end of the counter
shaft, and connected by the belt 58, passing under the guide pulleys 59, to the
main pulley 60, located on the main axle 1 of the machine.
In describing this invention it will be noticed that the gear for doubling the
speed of numbering, feeding and cutting apparatus is connected to the shaft 4,
which as before stated, derives the required motion by its gear connection to the
main driving shaft.
It will be also noticed that I have referred but briefly to the parts not imme-
diately involved in my invention, as for instance the necessary modifications for
working sheets may be made, such as a travelling band or equivalent from the
printing to the numbering machine.
