Improvements in Apparatus for or connected with the Feeding of
Material in Continuous or Practically Endless Lengths to
Printing and other Machines.
I, CHARLES LOUIS DUVAL, of 52, West Street, in the City of New York, State of
New York, United States of America, Merchant, do hereby declare the nature of this
invention to be as follows:--
The object of the invention is to enable the operators of machinery which requires
inaterial to be fed into it in substantially endless or continuous lengths to substitute
a new roll, spool, reel, or other package of material in place of the used up roll or
package, without stopping the machine to which the invention is applied. While
designed particularly for the paper, cloth or other fabric which is fed to rotary
printing presses, the invention is not so limited in its application, as will be clearly
understood from the following description.
Broadly and briefly stated, my invention as applied to printing presses contemplates
the joining of the end of the old roll when or before it is entirely used up to the end
of a new roll of paper, or other material, without stopping the machinery, so that a
continuous length of material may be fed to the press without stopping the press to
adjust and connect a new roll. Preferably, by the move of a single lever, the old roll
is cut off and the new roll connected on and fed into the press. The apparatus which
at the present time I think preferable for accomplishing the action is shown in the
accompanying drawing in two modifications.
Fig. 1 shows in side elevation one form of my apparatus as applied to paper, cloth,
and other fabrics, together with two rolls of the paper, one nearly used and the other
unused.
Fig. 2 shows in end elevation the connections and mounting of my presser-rolls.
Fig. 3 is a section on the plane 3-3 of Fig. 2, showing details of the apparatus.
Fig. 4 shows a preferable mounting of the paper rolls. Fig. 5 shows in section
similar to Fig. 3 a modification of my apparatus; and Fig. 6 is a cross section of the
pasting and cutting roll F1 of Fig. 5.
Throughout the drawings, similar letters of reference indicate similar parts.
I will first describe the apparatus shown in Figs. 1, 2 and 3.
The roll of paper that is nearly exhausted is shown at R and the new roll at R¹.
p¹.
The paper unwound from the two rolls is shown respectively at r,
Mounted in a suitable housing or frame B, are the two rolls B, B¹ pressed
together by a spring B", so as to apply pressure to the paper' as it passes
[Pr

page_text: between them, preferably all the rolls in the apparatus are mounted on friction
bearings, such as ball bearings. The course of the paper through the rolls R, is
clearly indicated in the figure and it' will be convenient to follow its course,
describing the various apparatus through which it passes in succession. This
paper passes between the fixed knife K and the movable knife or cutter J preferably
having serated or tooth-cutting edges, thence over the plate B11 and between the
slightly separated roller C, C, thence over plate or table D" and between pressure
rollers B, B¹ onto or over plate or table B¹. The knife J and the rollers C, C¹ are
controlled by the hand lever H. By depressing the handle H, the knife J cooperates
with knife K and cuts or severs the paper . By the same movement the
rollers C, C¹ are pressed together, causing the end of the other roll of paper R¹ (the
paper being lettered r¹) to be pressed against the paper by the rollers C, C¹ and
fed forward with it into the rolls B, B¹. The end of the paper having been
properly glued or pasted in any manner on its under surface, is united to the end
or piece by rolls C, C¹ and the joint made additionally secure by the rollers B, B¹,
which may be heated. The paper r¹ is kept in position for the operation by means
of the suitable supports F, just in front of the roll C, and by means of the idler
roll E. In order to avoid a jerk upon the roll R¹ a few yards of it may be drawn
loose and looped up on a wooden or other temporary table G. When the handle H
has been depressed and the end of the paper 1 thereby connected and started, the
roll R¹ may be turned or started by the hand of the operator, so as to avoid a sudden
jerk and the possible rupture of the paper +1. When in turn the roll R¹ becomes
greatly diminished in size, a new roller is put in the place of R and its end brought
up in position between the rolls C, C¹, and suitably pasted on the upper surface;
when it is time to cut off the remnant of roll R¹, the handle H is raised, instead
of lowered. The knife J then cooperates with knife K' and cuts off the paper r¹,
and simultaneously the rolls C, C₁ are pressed together, uniting the pasted end
of the new roll which has replaced roll R, with the cut end of the paper . In
short, the apparatus is symmetrically arranged to cut and unite either the lower or
upper paper with the opposing end of a new roll. The idler may be put in place
only a moment or two before the splicing of the paper is to take place, or it
may be left in continuous operation, as desired.
The movable knife J and rollers C, C¹, are mounted and controlled as follows:
The knife J is mounted to travel up and down in a slot in the framing D and is
connected with the lever H by link L, so that an upward or downward movement of
the handle causes a movement of the knife J in a similar direction.
The two rolls C, C¹ are mounted in suitable bearings in a vertical slot in the frame D
as shown in Figs. 1 and 2, P indicating the sliding journal boxes. A rubber
spring normally holds the rolls C, C¹ a half or three-quarters of an inch apart.
A bolt q may be employed to adjust the rubber spring Q to hold the rollers
precisely the distance apart desired. The plates p are secured to, and they move
with, the journal boxes P. Normally the weight of both rolls rests upon the
rubber spring Q¹ below, while a similar rubber spring or cushion Q¹ limits the
upward movement of the rollers. A slotted link or slide O encloses and plays upon
the journal boxes P, the boxes being normally at the extreme ends of the link O.
This link O is connected by rod or link M with the lever H, so that nomally
the lever H. may be horizontal, being supported by means of the link M and
slide O. The lever H in turn supports the knife J in its central position, as shown
in Fig. 3. When now the lever is drawn down, besides operating the knife J it
draws down the slide O, thereby acting directly on the upper roll and drawing it
downwards against the roll C¹, which is held up against it by the rubber springs Q¹.
The spring Q, offers no considerable resistance. When the lever is released after
the splice has been made, the spring Q raises the roller C and restores the lever and
knife J to central position. When the lever is raised, on the other hand, to cut the
paper, it forces up the slide 0, thereby pressing the roll C¹ up against roll C,
which rests against the upper spring cushion Q. The rubber spring Q is also
compressed as before,

I prefer not to have the width of the splice between the two sheets of paper, more
than two inches, or thereabouts, and not to have the paste extend either to the
extreme edges of the splice, or to the lateral edges of the paper. If this precaution
is taken, no danger of gumming any of the running parts or rollers occurs.
accomplish this in the apparatus shown in Figs. 1, 2 and 3, the end of the new roll
may be pasted cross-wise before insertion, with a trace of paste about two inches wide
and half an inch back from the margin and end of paper. The tip of the pasted
end should extend just between the rollers C C and the knives K, J, K¹ should be
located two and one half to three inches in front of the centers of the rolls. This
will cause the paper to be cut and joined so as to overlap about a half an inch beyond
the paste.
In Figs. 1, 2 and 3, I have assumed that there is sufficient space to alternately
mount the new rolls of paper in the upper and lower positions, the plate G¹ shown in
dots being temporarily put in place to hold the looped up slack of the lower roll at
starting, just as plate G supports the loops of the upper paper r¹. In Fig. 4, how-
ever, I show what I consider the best way of mounting these rolls, a minimum of
space being required. This is desirable in quadruple and octuple presses, though
even in such presses, the rolls may be mounted outside of the press and the paper run
into the desired position after leaving the roll. In Fig. 4, R¹ shows a new roll, just
started, which is mounted in the slot in the hanger or support P¹ pivotted at p¹ to
the upright T of the frame of the press. The lower end of the hanger or strap T¹ is
secured in any desired manner. By being pivotted at t¹, it may be turned out of the
way, so as to permit the introduction of the new roll axially into place, and the strap
then turned down to receive the end of the tubular shaft on which the roll is wound.
A new roll may weigh from twelve to fourteen hundred pounds. When it is com-
pletely unwound, the shaft or roller at its center may weigh from forty to fifty
pounds. By connecting a heavy spring onto the end of the shaft of the roll, as shown
by the dotted lines in Fig. 4, I cause the roll to be automatically drawn up, as it gets
lighter, until it assumes the position shown at R in the figure, the spring Sp accom-
plishing the result and holding it as shown. It will be seen by the lines of feed of
the paper that notwithstanding the great variation in the size of the roll, the
line of feed is at all times in approximately the same position. It will also be seen
that when the roll is nearly used up, and has reached the position R, a new roll R¹
may be slid into place and mounted, without disturbing the operation of roll R. As
soon, however, as the new roll has been put in place and the splice made, and the old
roll R cut off, the old roll may be removed from the upper end t¹ of the supporting
slot t. After the removal of the old roll, the spring Sp may be drawn down and
hooked on to the shaft of the roll R¹.
Of course, both ends of the rolls may be
mounted and operated in the same way. It will now be seen that when the rolls are
mounted as in Fig. 4, the end r¹ of the new roll R¹ is invariably applied to the
paper from beneath, instead of alternately above and below, as in Figs. 1 and 3.
Therefore, the double operation of the knife J becomes unnecessary, it being sufficient
to cut off the upper paper and press together the rollers C C¹.
will, now, in connection with Figs. 5 and 6, describe a modification of my
apparatus, which is self-pasting and which is particularly suited to a confined space
and to rolls mounted as in Fig. 4. Instead of the rolls B, B¹, I may have four
rolls, B and B and b, 61, the tables D1, D¹¹ may be placed as shown. The end of
the new roll R' is run on to the table D1 and there held by the downward
pressure of the guard f, which will be presently described. The upper paper r
from the nearly exhausted roll R runs over the supporting guide table F" thence
under the superposed plate f¹ into the rolls B B'. At F is shown a pasting roll
which also carries a cutter, more fully shown in Fig. 6 at J¹. When the handle H¹
is depressed, the pasting roll is forced up against the paper on the face of the
plate and the paste applied by the rotation of the roller F When the roller
is turned so as to bring the knife J¹ against the paper, the paper r is severed. The
depression of the handle H¹ also depresses roller C against feeding roller C¹¹,
causing the roller C¹¹ to act upon the paper r', immediately feeding it forward.. An

page_text: operator should start the roll R', so as to prevent the paper 1 being held back by
the inertia of the roll R¹. The roll may be driven at the right speed to
correspond with the other rolls of the press in any desired manner. I have shown
sprocket wheel cc' and sprocket chain connections C. Preferably the rolls B, B1, b, b1
will be all geared together, so as not to depend upon the paper for their move-
ment. The dotted circles 11111 show the pitch circles for the gears which
connect B and b. The other pitch circles between the rolls B and B' and
between bb1 correspond in size with the rolls themselves and so cannot be shown
in the drawing. There now remains to be explained only the details of the parts
between the two papers r², Fig. 5. At d dare shown in section supporting lugs,
which form part of the housing or casing of the apparatus. In these lugs, in the
recesses shown, is supported the casting or bracket E¹ which carries the guide
plate E for the upper paper r. The bracket E' is readily movable by raising left-
hand end out of the lug d¹ and then drawing it to the left, the guard f amply
protecting the knife J' and preventing its catching in anything. The bracket E¹
carries the band lever H¹ by means of the slots in the depending projections as
shown at e. In these slots, fit studs or trunnions of the lever H¹. A spring S
tends to draw the lever to the upper end of these slots and at the same time to
turn the lever so as to raise the handle and depress the guard f against the
table I)11.
In this position, also, the roller C is clear of the roller C¹¹ When it
is time to introduce a new roll of paper R, the bracket E with its connected parts,
is raised by hand under the paper and put in place in supporting lugs d, d' as
shown in Fig. 5. This causes the paper to take the course shown in the figure,
instead of running horizontally into the rolls B, B'. This, therefore, affords room
for the introduction of the end of the new roll, R to the position shown in the
figure. Preferably the bracket E¹ is put in place a few minutes before the
roll R¹ is mounted. Then the roll is mounted, preferably as described in connection
with Fig. 4. Its end, is then pushed in under the spring pressed-guard f,
which holds it from falling back or drawing out before it is needed. When, now,
the lever His shoved down, the roller C presses the paper 1 against the roller C¹¹,
and thereby feeds it forward toward the rolls B, B¹. Simultaneously, the guard fis
raised from the paper and the pasting and cutting roller F¹ presses up against
the paper r, against the plate f¹, causing the pasting and cutting. The parts are
so proportioned that the in-feeding end properly meets the pasted portion of r
and is pressed and united with it by the successive rollers. The pasting and cutting
roller F is shown in cross sections in Fig. 6. The roller is preferably hollow and
contains a recess in which the knife J¹ which should have a serated edge, is secured.
The pasting surface may be of felt or other suitable fabric secured upon
segmental-shaped carriage and thereby screwed or otherwise secured to roller F¹ Its
circumferential width should be about two inches. An interval of a quarter or half
an inch should be left between the past surface and the cutter J. Gravity keeps the
cutter downwards when the roller is free to turn, but of course when pressed up in
action, the pasting surface F" and the cutter knife J¹ roll into successive contact
with the paper and perform their successive functions against the plate f¹. This
plate should have a rubber or wooden face at the point where the knife meets it,
so as to insure the penetration of the edge of the knife through the paper instan-
taneously.
a
As soon as the handle H is released-and it is depressed for a second or two only
_ the operation is complete, the roll R is removed as described in connection with
Fig. 4 and the bracket E¹, with its attached part is lifted out. The paste is renewed
as required upon the surface F11, of the pasting roll before it is again put in
use.
It will be understood that the several rolls described will all be of a length
commensurate to that of the rolls R, R¹, which is very often about seven feet. While
I have shown the support in side elevation in Figures 1, 4 and 5 at one end only, it
will be understood that the supports at the end of the several rolls will correspond;
and intermediate supports or bearings for the smaller rolls inay be used at the middle

page_text: of each roll. This is a matter which largely depends on the length and strength of
the small rolls.
So, also, there are various other details depending solely on mechanical expediency,
which I have omitted, because to describe them at length would obscure rather than
make clear the essentials and the operation of my invention.

Improvements in Apparatus for or connected with the Feeding of
Material in Continuous or Practically Endless Lengths to
Printing and other Machines.
I, CHARLES LOUIS DUVAL, of 52, West Street, in the City of New York, State of
New York, United States of America, 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 :-
The object of the invention is to enable the operators of machinery which requires
material to be fed into it in substantially endless or continuous lengths to substitute
a new roll, spool, reel or other package of material in place of the used. up roll or
package, without stopping the machine to which the invention is applied. While
designed particularly for the paper, cloth or other fabric which is fed to rotary print-
ing presses, the invention is not so limited in its application, as will be clearly

continuous length of material may be fed to the press without stopping the press to
adjust and connect a new roll. Preferably, by the move of a single lever, the old
roll is cut off and the new roll connected on and fed into the press. The apparatus
which at the present time I think preferable for accomplishing the action is shown in
the drawing filed with my provisional specification in two modifications.
Fig. 1 shows in side elevation one form of my apparatus as applied to paper, cloth,
and other fabrics, together with two rolls of the paper, one nearly used and the
other unused.
Fig. 2 shows in end elevation the connections and mounting of my presser-rolls.
Fig. 3 is a section on the plane 3-3 of Fig. 2, showing details of the apparatus.
Fig. 4 shows a preferable mounting of the paper rolls.
Fig. 5 shows in section similar to Fig. 3 a modification of my apparatus; and
Fig. 6 is a cross section of the pasting and cutting roll F¹ of Fig. 5.
Throughout the drawings, similar letters of reference indicate similar parts.
I will first describe the apparatus shown in Figs 1, 2 and 3.
The roll of paper that is nearly exhausted is shown at R and the new roll at R¹.
The paper unwound from the two rolls is shown respectively at r, and r¹.
Mounted in a suitable housing or frame D, are the two rolls B, B¹ pressed together
by a spring B, so as to apply pressure to the paper as it passes between thein,
preferably all the rolls in the apparatus are mounted on anti-friction bearings, such
as ball bearings. The course of the paper through the 'rolls R, is clearly indicated in

page_text: the figure and it will be convenient to follow its course, describing the various apparatus
through which it passes in succession. This paper passes between the fixed knife K
and the movable knife or cutter J preferably having serated or tooth-cutting edges,
thence over the plate D and between the slightly separated rollers C, C' thence over
plate or table D and between pressure roller B, B1 on to or over plate or table D'.
The knife J and the rollers C, C are controlled by the hand lever H. By depressing
the handle H, the knife J co-operates with knife K and cuts or severs the paper r.
By the same movement the rollers C, C are pressed together, causing the end of the
other roll of paper R' (the paper being lettered 1) to be pressed against the paper
by the rollers C, C and fed forward with it into the rolls B, B'. The end of the paper r¹
having been properly glued or pasted in any manner on its under surface, is united
to the end or piece by rolls C, C and the joint made additionally secure by the
rollers B, B', which may be heated. The paper is kept in position for the opera-
tion by means of the suitable supports F, just in front of the roll C, and by means
of the idler roll E. In order to avoid a jerk upon the roll R¹ a few yards of it may
be drawn loose and looped up on a wooden or other temporary table G. When the
handle H has been depressed and the end of the paper thereby connected and
started the roll R' may be turned or started by the hand of the operator, so as to
avoid a sudden jerk and the possible rupture of the paper. When in turn the
roll R¹ becomes greatly diminished in size, a new roll is put in the place of R and
its end brought up in position between the rolls C, C', and suitably pasted on the upper
surface; when it is time to cut off the remnant of roll R', the handle H is raised
instead of lowered. The knife J then co-operates with knife K¹ and cuts off the
paper, and simultaneously the rolls C, C' are pressed together, uniting the pasted
end of the new roll which has replaced roll R, with the cut end of the

The movable knife J and rollers C C¹ are mounted and controlled as follows: The
knife J is mounted to travel up and down in a slot in the framing D and is connected
with the lever H by link L, so that an upward or downward movement of the handle
causes a movement of the knife J in a similar direction.
A
The two rolls C C₁ are mounted in suitable bearings in a vertical slot in the
frame D as shown in Figs. 1 and 2, P indicating the sliding journal boxes. A rubber
spring Q normally holds the rolls C, C¹ a half or three-quarters of an inch apart.
bolt q may be employed to adjust the rubber spring Q to hold the rollers precisely
the distance apart desired. The plates p are secured to, and they move with, the
journal boxes P. Normally the weight of both rolls rests upon the rubber springs Q
below while a similar rubber spring or cushion Q limits the upward movement of the
rollers. A slotted link or slide O encloses and plays upon the journal boxes P, the
boxes being normally at the extreme ends of the link O. This link O is connected
by rod or link M with the lever H, so that normally the lever H may be horizontal,
being supported by means of the link M and slide O.
The lever H in turn supports
the knife J in its central position, as shown in Fig. 3. When now the lever is drawn
down, besides operating the knife J it draws down the slide O, thereby acting directly
ou the upper roll C and drawing it downwards against the roll C¹, which is held up
against it by the rubber springs Q¹. The spring Q offers no considerable resistance.
When the lever is released after the splice has been made, the spring Q raises the
roller C and restores the lever and knife J. to central position. When the lever is
raised, on the other hand, to cut the paper 1, it forces up the slide O, thereby
pressing the roll C¹ up against roll C, which rests against the upper spring cushion Q¹.
The rubber spring Q is also compressed as before.
I prefer not to have the width of the splice between the two sheets of paper, more
than two inches, or thereabouts, and not to have the paste extend either to the
extreme edges of the splice, or to the lateral edges of the paper. If this precaution
is taken, no danger of gumming any of the running parts or rollers occurs.

wide and half an inch back from the margin and end of paper. The tip of the
pasted end should extend just between the rollers C C and the knives K, J, K¹ should'
be located two and one half to three inches in front of the centres of the rolls. This
will cause the paper to be cut and joined so as to overlap about half an inch beyond.
the paste.
In Figs. 1, 2 and 3, I have assumed that there is sufficient space to alternately
mount the new rolls of paper in the upper and lower positions, the plate G¹ shown
in dots being temporarily put in place to hold the looped up slack of the lower roll.
at starting, just as plate G supports the loops of the upper paper r¹. In Fig. 4,
however, I show what I consider the best way of mounting these rolls, a minimum of:
space being required. This is desirable in quadruple and octuple presses, though
even in such presses, the rolls may be mounted outside of the press and the paper
run into the desired position after leaving the roll. In Fig. 4, R¹ shows a new roll,
just started, which is mounted in the slot in the hanger or support T¹ pivotted at t¹ to
the upright T of the frame of the press. The lower end of the hanger or strap T₁
is secured in any desired manner. By being pivotted at t¹, it may be turned out of
the way, so as to permit the introduction of the new roll axially into place, and the strap
then turned down to receive the end of the tubular shaft on which the roll is wound.
A new roll may weigh from twelve to fourteen hundred pounds. When it is com-
pletely unwound, the shaft or roller at its centre may weigh from forty to fifty
pounds. By connecting a heavy spring on to the end of the shaft of the roll, as
shown by the dotted lines in Fig. 4, I cause the roll to be automatically drawn up, as
it gets lighter, until it assumes the position shown at Rin the figure, the spring Sp
accomplishing the result and holding it as shown. It will be seen by, the lines of
feed of the paper that notwithstanding the great variation in the size of the
roll, the line of feed is at all times in approximately the same position. It will also

of roll R. As soon, however, as the new roll has been put in place and the splice made,.
and the old roll R cut off, the old roll may be removed from the upper end [11
of the supporting slot. t. After the removal of the old roll, the spring Sp may be
drawn down and hooked on to the shaft of the roll R¹.. Of course, both ends of
the rolls may be mounted and operated in the same way.
It will now be seen
that when the rolls are mounted as in Fig. 4, the end of the new roll R¹ is
invariably applied to the paper from beneath, instead of alternately above and
below, as in Figs. 1 and 3. Therefore, the double operation of the knife J becomes
unnecessary, it being sufficient to cut off the upper paper r and press together the
rollers C C¹.
I will, now, in connection with Figs. 5 and 6, describe a modification of my
apparatus, which is self-pasting and which is particularly suited to a confined space.
and to rolls mounted as in Fig. 4. Instead of the rolls B B¹, I may have four
rolls, B and B11 and 6 61, the tables D¹ D11 may be placed as shown. The end of the
new roll R¹ is run onto the table D and there held by the downward pressure of the
guard f, which will be presently described. The upper paper r from the nearly
exhausted roll R runs over the supporting guide table E thence under the superposed
plate finto the rolls B B¹. At F¹ is shown a pasting roll which also carries a cutter,
more fully shown in Fig. 6 at J¹. When the handle H¹ is depressed, the pasting roll
is forced up against the paper on the face of the plate 1 and the paste applied by
the rotation of the roller F¹. When the roller is turned so as to bring the knife J¹
against the paper, the paper is severed. The depression of the handle H¹ also
depresses roller C1 against feeding roller C¹, causing the roller C₁ to act upon the
paper, immediately feeding it forward. An operator should start the roll Ŕ¹, so as
to prevent the paper being held back by the inertia of the roll R¹. The roll C₁
may be driven at the right speed to correspond with the other rolls of the press in
any desired manner. I have shown sprocket wheels c c and sprocket chain,.

connections C¹¹. Preferably the rolls B, B¹, b, b¹ will be all geared together, so as
not to depend upon the paper for their movement. The dotted circles 611 6111 show
the pitch circles for the gears which connect B" and b. The other pitch circles
between the rolls B and B and between bb correspond in size with the rolls
themselves and so cannot be shown in the drawing. There now remains to be
explained only the details of the parts between the two papers r¹, Fig. 5. At d d¹
are shown in section supporting lugs, which form part of the housing or casing of
the apparatus. In these lugs, in the recesses shown, is supported the casting or
bracket E¹ which carries the guide plate E" for the upper paper r. The bracket E¹
is readily movable by raising left hand end of the lug and then drawing it to
the left, the guard f amply protecting the knife J' and preventing its catching
in anything. The bracket E' carries the hand lever H' by means of the slots in
or
In these slots, fit studs
the depending projections as shown at e.
of the lever H¹. A spring
tends to draw the lever to the upper end of these
slots and at the same time to turn the lever so as to raise the bandle and
depress the guard f against the table D". In this position, also, the roller C is
clear of the roller C. When it is time to introduce a new roll of paper R, the
bracket E' with its connected parts, is raised by hand under the paper r and put in
place in supporting lugs d d' as shown in Fig. 5. This causes the paper to take
the course shown in the figure, instead of running horizontally into the rolls B B'.
This, therefore, affords room for the introduction of the end of the new roll R to
the position shown in the figure. Preferably the brackets E¹ is put in place a few
minutes before the roll R₁ is mounted. Then the roll is mounted, preferably as
described in connection with Fig. 4. Its end is then pushed in under the spring
pressed guard f, which holds it from falling back or drawing out before it is needed.
When, now,
the lever H' is shoved down, the roller C111 presses the paper r¹ against
the roller C, and thereby feeds it forward towards the rolls B B'. Simultaneously
the guard f is raised from the paper and the pasting and cutting roller F¹ presses
up against the paper r, against the plate f¹, causing the pasting and cutting. The
parts are so proportioned that the in-feeding end r' properly meets the pasted
portion of and is pressed and united with it by successive rollers. The pasting
and cutting roller F' is shown in cross sections in Fig. 6. The roller is preferably
hollow and contains a recess in which the knife J' which should have a serated edge,
is secured. The pasting surface F may be of felt or other suitable fabric secured
upon a segmental shaped carriage and thereby screwed or otherwise secured to
roller F. Its circumferential width should be about two inches. An interval of a
quarter or half an inch should be left between the paste surface and the cutter J'.
Gravity keeps the cutter downwards when the roller is free to turn, but of course
when pressed up in action, the pasting surface F" and the cutter knife J¹ roll into
Buccessive contact with the paper and perform their successive functions against the
plate . This plate f¹ should have a rubber or wooden face at the point where the
knife meets it, so as to insure the penetration of the edge of the knife through
the paper instantaneously.
As soon as the handle H¹ is released-and it is depressed for a second or two only,-
the operation is complete, the roll R is removed as described in connection with Fig. 4
and the bracket E¹, with its attached part is lifted out. The paste is renewed as
required upon the surface F1, of the pasting roll before it is again put in use.
It will be understood that the several rolls described will all be of a length
commensurate to that of the rolls R, R¹, which is very often about seven feet. While
I have shown the support in side elevation in Figures 1, 4 and 5 at one end only, it
will be understood that the supports at the end of the several rolls will correspond ;
and intermediate supports or bearings for the smaller rolls may be used at the iniddle
of each roll. This is a matter which largely depends on the length and strength of
the small rolls.
So, also, there are various other details depending solely on mechanical expediency,
which I have omitted, because to describe them at length would obscure rather than
make clear the essentials and the operation of my invention.

page_text: Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I
claim is
1. In combination, for the purposes specified, means for cutting the material
passing through the apparatus and means for simultaneously uniting therewith the
end of another piece of the said material, whereby the supply may be continuous and
endless.
2. In combination in apparatus for supplying material in continuous lengths
without stopping, means for simultaneously cutting off the end of one portion and
applying thereto and uniting the end of a succeeding portion, substantially as set
forth.
3. In combination, in apparatus for feeding material from rolls in continuous
lengths, means for cutting off the end of an exhausted roll without stopping, and
means for applying thereto the pasted or suitably prepared end of a succeeding roll of
the material, and means for applying pressure to the splice without stopping,
substantially as set forth.
4. In combination, in apparatus for feeding material from rolls in continuous
lengths, means for simultaneously feeding forward the end of a new roll, applying
paste and cutting off the end of the old roll, and means for pressing the ends to be
joined together, without stopping, substantially as set forth."
5. In apparatus for delivering material successively from several rolls or other
sources of supply, without stopping, mechanism for splicing or joining the ends
together while in motion, substantially as set forth.
6. In combination with a roll or reel of material and with the shaft or spindle
thereof, automatic means for changing the position of said shaft or spindle as the
weight of material decreases.
7. In combination with a roll or reel of material, and with the shaft or spindle
thereof, automatic means for changing the position of the said shaft or spindle from
its initial position as the weight of material decreases, and means for receiving a new
roll or reel in the initial position before exhausting the preceding said roll or
reel.
8. In combination in the supports for rolls or reels of material, the pivotted or
movable support T¹ provided with a slot or way for the spindles or shafts of said rolls
or reels.
9. In combination, in the supports for rolls or reels of material, the pivotted or
movable support T¹ provided with a slot or way for the spindles or shafts of said rolls
or reels, and the fixed support T provided with a continuation of the said slot or
way.
10. In combination, in the supports for the rolls or reels of material, guides or sup-
ports for the shafts or spindles of the rolls or reels, a portion of said guides or supports
for one end of the shafts or spindles when in initial position, being adjustable to
permit the free movement of the full rolls or reels longitudinally into the initial
position, and means for displacing the rolls or reels from the said original position
transversely to their axes before they are completely unwound, whereby the succeed-
ing rolls or reels may be inserted lengthwise before the previous rolls or reels are
exhausted.
