Improvements in Machines for Folding or Creasing Sheets of Paper
and the like.
I, CHRISTIAN HANS STOELTING, of 39, West Randolph Street, Chicago, County
of Cook, State of Illinois, United States of America, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly, described and ascertained in and by the following.
statement: :-
"
This invention relates to machines for creasing or folding sheets of a relatively
stiff paper or the like, for the purpose of imparting to the latter a greater capa-
city for flexure or bending along the line operated upon. The machine will
usually be employed for creasing or folding sheets of paper for use in books,
for the purpose of enabling one to produce what is known as a "flat opening
book." Such result has been heretofore attained by some special form of bind-
ing, but in those books where the leaves are removable, such as in temporary
binders and in loose leaved ledgers, the separate sheets are usually composite in
character; being constructed of the sheet or writing section proper and a bind-
ing or relatively narrow back section, which two sections are secured together
by a flexible hinge, usually of very thin muslin, linen, or the like, so that when
said leaves are secured between the covers of the book or binder along their
relatively narrow or back section, the thin flexible hinged portion will flex or
bend readily when the book is opened, and thus permit the book to be opened
out for the ready access to all portions of the section proper of the leaf. This
linen or hinge portion of the section is of varying width, there being sometimes
as much as an inch or more between the adjacent margins of the two sections of
the leaf; and a leaf constructed therewith is necessarily expensive to manu-
facture because requiring hand labor exclusively. Moreover, it does not con-
tain the maximum capacity for writing. That is to say, the entire part of the
leaf and hinge exposed to view when such a book is opened cannot be utilized
for writing purposes because of this hinge section.
It is, therefore desirable to use a sheet of paper as a leaf of such book which
shall have a flexible section across it at such distance from its rear margin as
to leave a sufficient section or portion of the leaf to be acted upon by the binder
or other retaining portion of the book, which section shall not only be flexible
and enable the leaf to bend in order to form a flat opening book, but which may
be utilized for the purpose of making records thereon in writing or otherwise,
the same as upon other portions of the sheet. Several means have been sug-
gested heretofore for producing such flexible section on a sheet of paper, includ-
ing that of folding or creasing the leaf along a plurality of parallel lines rela-
tirely near to each other, in such manner that the leaf may be straightened or
flattened out after the crease has once been made; and it is the purpose of this
present invention to produce a machine for automatically making such creases.
The invention consists first in the mechanism for bending the sheet of paper

page_text: and crimping or setting the bend between co-acting jaws. Second, it consists
in the adjustment of the machine whereby the crease or bend in the paper shall
be so slight with respect to its writing surface as to enable one to write with the
usual pen and ink or other materials upon the sheet across such crease or bend
without having the latter interfere with the appearance or the character of the
record made thereon, the crease or bend being at the same time so permanently
made as to constitute a freely movable hinge along the line of the crease. Third,
it consists in suitable mechanism for flattening out the several bends or creases
in the sheet after they have been made. Fourth, it consists in the mechanism
for gripping two portions of the sheet between a set of clasping jaws and means
for automatically advancing a knife or tucker blade to start the fold between said
gripping jaws in the right direction preparatory to the bringing of said jaws
together for the purpose of making the crimps or folds. Fifth, it consists in
automatically feeding the sheet of paper step by step between each creasing or
folding operation a desired distance whereby any given number of parallel creases
or folds may be given to the sheet. Sixth, it contains in the mechanism for
automatically stopping the machine after a given number of operations. Seventh,
it consists in the various novel devices and combinations of devices herein
illustrated and described, together with their mechanical equivalents, and more
particularly pointed out in the claims appended hereto.

Before proceeding to describe the machine in detail with reference to the
accompanying drawings, I will first describe the operation of crimping, as per-
formed by said machine, by reference to Figure 1 of the drawings, which is
a diagramatic view in nine sections or parts, illustrating the successive steps
of the machine herein described in crimping a sheet of paper. In this view, I
have indicated in each nine sections simply the upper and lower clamping
blocks, the upper and lower tucker blades and the sheet of paper, the sections
being lettered in consecutive order 1ª, 1b, 1°, 1ª, &c., as the operation progresses.
Referring now to the first section 1", A A¹ indicate the lower jaws and B B
the upper jaws, the jaw A being stationary and the jaw B having a vertical move-
ment to and from the block A but no movement laterally thereof. The jaws A¹
and B are each movable, the jaw B¹ being movable vertically as the block B is

page_text: movable, and the two jaws A¹ B¹ being movable laterally to and from the jaws A
and B. C is a sheet of paper, c being the rear margin thereof in which it is
desired to form a flexible section or hinge which is made by creasing the same
in parallel lines at the points indicated within the brackets shown in Figure 1^
a lower vertically movable tucker blade, and D₁ an upper vertically movable
tucker blade. These same letters will be used throughout the different sections.
of this diagram.
The operation of the machine is in this respect is as follows: The tuckers D
and D and the upper and lower jaws being separated, as indicated at 1, the
sheet of paper C is fed between the same a proper distance. The vertically
movable jaws B and B will now be caused to descend and clamp the sheet
firmly upon the jaws A and A' and the upper blade I will be moved down-
wardly and start the bend in the sheet, as indicated at 1b. Simultaneously with
the completion of this downward movement of the blade D¹, the two jaws A¹
and B will be caused to move laterally toward the jaws A and B, as indicated.
As soon as the blade or knife 11 has merely started the bend in the sheet of
paper C, it is immediately withdrawn, as indicated at 1 and the jaws A' and B'
continue to move toward A and B until they reach the position shown in the
diagram 1 in which the sheet will be bent or folded in a downwardly directed
fold, with creases at c¹ c² 3. The next operation in the machine will be to retract
the jaws AB' as shown in the diagram 1" until they are separated to their
greatest extent, from the jaws A and B, and are ready for insertion between them
of the lower blade D. The blade D is now caused to move upwardly between
the jaws until it comes in contact with and starts an upward bend in the sheet,
as indicated in the diagram 1, when it is withdrawn, as shown in the diagram 18
and the jaws A' B¹ are caused to move laterally toward the blocks A and B as
before. Said movable jaws continue their movement toward the jaws A and B
and crimp the sheet as shown in diagram 1h, in the same manner as the sheet
was crimped along the line shown in diagram 1", with the exception that in
the latter instance the fold in the sheet is downward or below the horizontal,
while in the operation just described, it is folded upwardly, or above the hori-
zontal. The jaws A and B are now retracted laterally and by the time they
have reached their outermost position, the jaws B and B have been caused to
rise, thus releasing the sheet C. Suitable feeding mechanism is provided by
means of which the sheet is moved outwardly until the paper is carried a proper
distance to the right, as illustrated in diagram 1d at which time the upper
jaws B B are again moved downwardly to clamp the sheet between the same
and the lower pair of jaws, when the operation is repeated as before. This
creasing or folding continues until the last crease or bend formed is a predeter-
mined distance from the rear margin of the sheet, thus forming the sheet of
paper such as indicated in Figure 12 of the drawings.
It is deemed advantageous to bend each fold or crease in two directions, and
I, therefore, provided both the upper and the lower tucker blade for starting the
crimps or folds in the sheet, one in one direction and one in the other. I havo
also arranged to maintain the jaws B B₁ closed or clamped upon the jaws A A¹
with the sheet C between them during the reciprocating or lateral movement of
the jaws A B₁ against the jaw A B in order that this double crease, bend or
fold may be given to the sheet before it is fed along the required distance
for the next succeeding fold. It may be desirable, however, to
go
immediately
from the operation illustrated in diagram 1d to that illustrated in 1 and then
repeat 1, 1, 1, 14, as stated. The machine herein shown is so constructed that
one of the vertical sets of jaws, A¹ and B', in this instance, is movable laterally
toward the other jaw, and it will be apparent that this arrangement may be
reversed or that both may move a desired distance toward and from each other..
With this explanation of the purpose of my invention and of the essential fea-
tures, thereof, to wit, the clamping of the sheet, starting of the bend in the
right direction and then the creasing of the sheet. along that bend between the

page_text: adjacent faces of the crimping jaws, I will now proceed to describe the machine
which I have constructed to embody this invention.
As shown in said drawings, E designates the frame of the machine comprising
side members, consisting of legs or standards E and horizontal top members E;
said side members being joined together by upper and lower cross members E³ E'
and the standards on each side by intermediate transverse members EE. The
horizontal top members E2 are provided with upwardly extending projections of
pillow blocks E7 which form a support for a portion of the operative mechanism.
as will hereinafter appear.
For convenience of description, the upper jaws or blocks B B will be desig-
nated as the clamping jaws and the jaws A A' below as the crimping jaws,
although it will be noted that they all co-act both to clamp the sheet and to
crimp it, the clamping action herein referred to being that of engaging and
holding the sheet between the jaws in such manner that one set of closed or
clamped jaws may be moved toward the other set, or both sets moved toward each
other to perform the act of folding or creasing. With this in mind it is believed
that no confusion will arise from the arbitrary designation of the jaws A A¹ as
crimping jaws and the jaws B B as clamping jaws. The crimping jaw A is
stationary with the machine and may be made integral with the frame E if
found desirable. Said jaw is herein shown as formed on the rear portion of a
casting which constitutes part of the feeding table as will hereinafter more fully
appear. It will be understood that the jaws extend the entire distance between
the side members of the frame. The co-acting crimping jaw A' is mounted so
as to be laterally movable with relation to the jaw A but has no vertical move-
ment. Said jaw A is in the present instance supported between the upper hori-
zontal members E2 of the frame by means of integral tongues e on said frame
which engage grooves in the adjacent edges of the jaw A¹. The upper faces of
the jaws A A lie in the same horizontal plane. The movable crimping jaw A¹
is adapted to be normally held retracted from the jaw A to allow a space between
the same for the passage of the tucker blade D D¹. Said crimping jaw A¹ is
made relatively wide from front to rear of the machine and constitutes in effect
a table upon which the paper to be crimped is supported, and which table is
advanced as the crimping blades advance to their work in order to feed the
paper a distance forward required by the size of the crimp. Said extended part
of the jaw has, therefore, been termed a table in certain of the claims.
The means herein shown for holding such jaw in its retracted position are
as follows:
A2 A2 designates hollow cylindric bosses mounted on the lower side of the
jaw A on each side thereof adjacent to the frame members E. A³ A³ designate
a second set of hollow cylindric bosses mounted on the under side of the jaw A
with the bores thereof in alignment with the bores of said bosses A2. A¹ A¹
designate short guide rods mounted in said bosses A2 A3 the forward end of said
rods, with relation to the machine, being mounted rigidly within the bosses A²
and the rear ends thereof having sliding engagement with the bosses A³ as seen
in Figure 7 of the drawings. The rods A are of less diameter than the bores
within the bosses A4 and are provided adjacent to the forward end of said bosses
with rigid collars a between which and opposing shoulders in said bosses A³
are interposed spiral expansion springs a¹. With this construction, it will
be seen that when the jaw A is moved toward the jaw A in the act of crimping,
it will be moved against the action of the springs a¹. When the jaw is released,
therefore, said springs will act to return the same to its rearmost position as
seen in Figures 5, 6, and 7.
Any suitable means may be employed for moving the jaw A¹ inwardly upon
the jaw A. As herein shown, said jaw is provided on each side thereof adjacent
to the frame number A2 with tappet blocks A³ mounted on the lower surface of
the jaw. Said tappet blocks are adapted to be engaged by cam surface h formed
on sleeves H¹ mounted rigidly on a transverse shaft H which is journaled in

page_text: the opposite horizontal frame members E2 of the frame E. Said cam surfaces
are arranged to cause inward movement of the jaw A in each rotation of the
shaft H. The shaft H, which may be called the crimping shaft, extends out-
wardly beyond the frame E on the left hand side of the machine, as shown in
Figure 3 and 4, and is provided on the outside of said frame with a gear wheel H².
Said gear wheel is engaged by and receives motion from a smaller gear wheel M'
mounted upon a driving shaft M and adjacent to the outer end thereof; said
shaft M being provided on its opposite end outside of the frame E with a belt
pulley M² by means of which the shaft may receive motion from any suitable
source of power.
The bearings within which the shaft H is journaled are herein shown as made
adjustable to permit the movement of said shaft toward and from the jaw. The
frame members are provided with recesses within which are mounted two part
bearing blocks H* H Figure 13 which are recessed in their adjacent faces to
form a suitable bearing for said shaft. The part H3 of the block is provided in
its outer end with flanges 2 through which pass securing bolts H which are
mounted in any convenient manner in the frame members E¹. Locking nuts h³
have screw threaded engagements with the outer ends of the bolts which serve
to hold the bearing blocks and shaft in place in the frame. Between the inner
ends of the blocks H* and adjacent inner ends of the recesses are mounted
buffers H which permit the necessary movement of said bearing blocks within
the recess in the adjustment of said shaft. A coiled expansion spring would
obviously serve the same purpose and might be used instead of the buffer if
desired.
The movable crimping jaw A¹ is provided on its upper surface adjacent to
the forward edge thereof with an adjustable stop which limits the movement of
the sheet of paper when it is inserted between the clamping jaws. Said stop
consists in a transverse bar 133 mounted parallel with the adjacent edge of the
jaw, and two rearwardly extending arms B B attached to said bar B adjacent
to its opposite ends and adapted to be secured in the upper face of the jaw in
any convenient manner. As herein shown, the upper face of said jaw is provided
with grooves B B within which said arms B rest and slide. Said stops are
secured in place upon the jaw by means of set screws 16 16 which pass through
the arms and have screw threaded engagement with the jaw. In order to
provide movement of the stop on the jaw, by means of which the width of the
margin of the sheet may be regulated, said set screws engage elongated slots 137 B7
in the arms B. The middle portion of the adjacent jaw B₁ is cut away on its
under side to receive the bar 13 when said bar is at the limit of its movement.
With this construction, the width of the margin of the sheet between the crimped
section and the rear edge thereof may be regulated as desired. A single arm B*
may be employed to hold the bar B3 in place instead of two as shown.
The upper jaws B B are shown in plan view in Figures 2 and in cross section
in Figures 5, 6 and 7. Each of said jaws are so mounted as to have vertical
movement with relation to the jaws A A¹ and the rear jaw B₁ is mounted so
that it may be retracted from the jaw B when the lower jaw A¹ is retracted under
the action of the spring a', as described. Said jaws, as in the case of the
jaws A A, extend the entire distance between the upper frame members E²
but in the construction shown need not be engaged therewith. In order to
provide against lateral movement of said jaws B B with relation to the jaws A A¹,
said first mentioned jaws are provided on each end thereof with apertures, through
which extend upwardly projecting guide rods A which are rigidly secured at
their lower ends in the lower jaws A A'. Said upper jaws are provided on their
upper sides with bosses through which the guide rods A pass, to offer a more
substantial bearing for the same. In order that the jaws B B may be promptly
returned to their lower or clamping position when they have been raised suffi-
ciently to allow a sheet of paper to be passed thereunder, spiral expansion
springs X are herein shown as interposed between the upper ends of the bosses b.

page_text: and nuts a³ on the upper ends of the guide rods A. With this construction,
the jaws B B will be lifted against the force of the springs and when released
will be returned to their lower or clamping position thereby, in an obvious
manner. Said nuts a³ are made adjustable to permit the tension of the springs X
to be regulated and the jaws B B held upon the jaws A A¹ with varying force.
Means for raising said jaws B B₁ to permit a sheet paper to be passed there-
under are provided as follows; II designate two arms or levers pivoted between
their ends upon a transverse shaft which is non-rotatively mounted between
the pillow block E7 of the frame. To the outer or forward ends of said arms
are pivoted connecting links I¹ comprising parallel side members and cross
ends ; the lower end of said side members being pivotally engaged with lugs b¹
on the upper faces of the jaws B B by means of pivot pins or bolts 2. The
jaws B B with which the parallel members of the link are engaged having
lateral movement with relation to each other, said side members of the link are
herein shown as pivotally connected with the cross head by means of pivot
bolts by which the lower ends of said side members may be oscillated when
the jaw B is retracted from jaw B. This construction also permits said jaws to
be raised vertically upward without friction upon the guide rods A6 when the
rear end of the lever is depressed. When the arms or levers I have been con-
nected with the jaws B B' in the manner described, said jaws will be raised from
the jaws A A¹ by depressing the rear or free end. of said lever I in any con-
venient manner. This is in this instance accomplished by means of cams g
herein shown as formed on sleeves mounted adjacent to each end of a transverse
shaft G which is rotatively mounted between the rear sides of the pillow blocks E7.
When said shaft is rotated, therefore, the cams will act to depress the free
ends of the levers I and thereby raise the jaws B B. When said cams release
the lever, the spring X will act to promptly return the same to their lower posi-
tion as shown in the figures of the drawing. Said shaft G is provided near one
end thereof outside of the frame with a gear wheel G2 which intermeshes with
and received motion from a smaller gear wheel H above mentioned. In order
to obviate friction between the free end of the arm I and the sleeve G said arm
is shown as provided with an antifriction roller I².
The upper blade D¹ is supported upon and actuated by a lever F which is
mounted between its ends upon the shaft F between said levers or arms I just
described. Said lever F comprises a sleeve F, which is rotatively mounted upon
the shaft, to which are attached forwardly extending divergent arms 13 and a
rearwardly extending arm F located upon the sleeve centrally of the arms 13.
Connecting links f are pivotally attached to the forward ends of the arms F3
to the lower ends of which is pivotally secured the tucker blade D₁ as clearly
seen in Figures 7 and 8. Said lever FI is so arranged that when in the position
shown in Figure 7 of the drawing, the tucker blade D¹ will be at tlie upper
limit of its movement. To move said blade downwardly to crimp the paper
between the adjacent jaws, it is necessary that the rear or free end of the arm
be raised. For this purpose, the lever F is provided on its rear end with a
tappet surface f¹ which is adapted to be engaged by a cam g¹ on a sleeve G
mounted on the shaft G. With this construction, when the shaft is rotated so
that the surface g engages the tappet surface fl of the arm F1, the lever will be
oscillated and the blade attached thereto will be lowered between the two sets
of jaws and the paper clamped between the same, folded downwardly, as before
described. The inner faces of the frame are provided with guide blocks el
(Figures 2 and 8) which are provided with vertical grooves with which the
opposite ends of the blade D¹ have engagement and by which they are held from
lateral movement. The rear arm of the lever may be made of sufficient
weight to promptly return the blade to its upper position when the cam g¹
leaves the tappet surface f¹ thereon. I prefer, however, that this movement be
positively accomplished and have herein shown for this purpose a spiral spring. F
mounted upon the shaft F, one end of which is engaged in a collar Fe on the

page_text: shaft and the other end of which is engaged with an arm F7 extending rear-
wardly from the sleeve F2. The spring is so arranged that the lever is oscillated
against the action thereof and when released, the torsional action of the spring
will act promptly to return the lever to its normal position and raise the blade
upwardly. Said collar F is adjustably mounted on the shaft and may be moved
thereon to regulate the tension of the spring as desired.
The lower tucker blade 1) is mounted so as to be moved upwardly between
the crimping jaws and thereby crimp or fold the paper upwardly as seen at f
(Figure 1). Said blade is mounted upon and actuated by a lever J which is
pivoted between its ends upon a transverse shaft J vertically below the shaft F,
and mounted in the opposite sides of the frame. Said lever is of the same form
as the lever F above described comprising a sleeve J2 to which are attached for-
wardly extending divergent arms J and a rearwardly extending arm J located
upon the sleeve centrally between the arm J³. To the forward ends of the
arms J3 are pivotally attached connecting links ; the upper ends of which engage
the lower blade D. As herein shown, the blade is provided with slots d through
which pass the guide rods A as clearly seen in Figure 5. Said necessary upward
imovement of the blade and serve also to support said blade in its lower position.
The blade is actuated to move upwardly between the crimping jaws by depress-
ing the rear end of the arm J of the lever J thereby raising the arms J3 and the
blade thereto attached. In the present instance this is accomplished by the same
shaft by which the upper blade is moved downwardly, as heretofore described.
As shown, in the rear end of the arm J of the lever J is provided with a pivot-
ally engaged actuating bar J which extends upwardly with its extreme upper
end adjacent to the sleeve G³. The upper end of said arm is provided with a
tappet surface which is adapted to be engaged by the cam g¹ of said sleeve G₁,
through the medium of which the rear end of the lever is depressed and the
blade D attached thereto raised into its operative position. Said actuating
bar J is shown in Figures 4 and 5 as passing through a suitable bearing, Es
in the transverse bar E3 of the frame, by means of which the upper end thereof
is held in engagement with the sleeve G³. Said lever J is engaged by a spring Jo
which is interposed between the sleeve J2 thereof and a collar. J on the shaft,
and which acts to positively return the knife to its lower position as in the con-
struction of the spring F5 above described. Said collar J7 is also adjustably
mounted upon the shaft and serves by moving the same upon the shaft to regu-
late the tension of the spring as desired..
The apparatus herein shown and described, is designed for crimping or fold-
ing a sheet of paper both upwardly and downwardly as shown in the diagra-
matic view of Figure 1. It will be seen, therefore, that the cam g operates both
tucker blade D1 to move in opposite directions to start the fold on each side
of the paper during one rotation of the shaft G and that, each fold is crimped
immediately after being started by the blade, the shaft H actuating the movable
crimping jaw A¹ rotates twice while the shaft G passes through one rotation.
The gear wheel G2 and H³ are, therefore of such size and the cam g and h.are
arranged to such angular distance apart on their respective shafts that the
crimping jaw A will be moved inwardly at the instant cach blade is moving to
and touching the sheet to start the fold in the paper; the. blade, of course, being
rapidly retracted out of the way of the crimping jaws. as soon as the fold is
started in the desired direction.". If it be desirable to crimp the paper in but
one direction, it will only be necessary to remove one of the tucker blades and
its actuating mechanism and change the size of the gear wheels H³ G2, the
angular relation of the cam surfaces remaining the same in either case.
As herein shown the jaws A A B B do not come in contact with each other
when the sheet of paper is crimped between the same but are provided on their
under surfaces with projecting faces, a² a³ 2.3 which are arranged to co-act with
each other in the vertical and lateral movements of the jaws. Said faces are
preferably of steel and, as stated, project beyond the adjacent inner surfaces

page_text: of the jaws so that when they are in contact with each other, a space is left
between the body of said jaws within which the tucker blade D D₁ may rest.
It will be unnecessary, therefore, that the knives be moved beyond the upper
and lower planes of the jaws but only sufficient to clear the said steel faces.
Said faces a a³ 62 63 are shown as made separate from the jaws but may be
formed integral therewith if desired.
Said frame E is provided in front of the tucker blade D D¹ with a feed table E⁹.
Said table is mounted upon forward extensions E10 of the upper horizontal bar E³
of the frame which are supported from the standards E¹ of the frame by obliquely
arranged braces E. Said braces El and horizontal supporting braces E10 may
be cast integral with the frame E if desired, and the table E may be made of
any suitable material and secured to the frame in any convenient manner.
Between the outer edge of the table and the tucker blade D D¹ are arranged
a pair of feed rollers K K¹. In the present instance, the casting forming the
stationary crimping jaw A is extended forwardly to slightly beyond the stan-
dards E¹ of the frame at which point it is connected with the table E. The
upper surface of the table and the casting forming the jaw A lie in the same
horizontal plane so that the forward portion of the said casting forms the rear
margin of the feed table. The lower roller K¹ is mounted in a depression or
groove in the forward part of the casting forming the jaw A, so that the upper
surface thereof lies in the horizontal plane of the table. Said roller is rotatively
mounted at its opposite ends in the opposite side members of the frame. The
upper roller K is mounted above said roller K¹ to co-act therewith but in such
manner that it may be raised vertically therefrom so that the sheet of paper
may be thrust between the same and between the upper and lower sets of jaws
when the said jaws are raised in the manner heretofore described. As herein
shown said roller is mounted at each end in a movable journal block K², which
block is mounted between upwardly extending parallel guides E2. secured upon
the upper surface of the casting forming the stationary jaw A. With this con-
struction, the upper roller K may be raised from the roller K¹ to permit a sheet
of paper to be inserted between the same and between the clamping jaws; it
being understood that the sheet will be inserted at once between said jaws in such
manner that the first crimp made therein will be that adiacent to the front margin
thereof from whence the sheet will be fed forward until the crimped section of
the sheet extends to a predetermined distance from the rear margin of the
same. The upper roller K is shown in the drawing as in its lower or operative
position but is so mounted that it will normally stand retracted from the
roller K as will hereinafter appear. The means for actuating said roller to
bring it into its operative position are as follows:
The co-acting portions of the rollers do not extend full distance between the
side members of the frame E as clearly shown in Figure 2 of the drawing, but
are provided on each end with short shaft sections which form the journals upon
which the rollers, turn. Upon the shaft between the co-acting portion of the
roller K and the side members of the frame are mounted bearing links K³. Said
links K pass downwardly through openings in the castings upon which the
stationary jaw is formed, adjacent to each end thereof, and are provided with
slots adapted to receive the shaft of the roller K¹ by means of which said links
are moved upon the shaft of the roller K¹ when they are moved to raise the
upper roller K. To the lower end of said links K are pivotally attached the
forward ends of levers K, the rear ends of said levers being pivotally connected
with the frame by means of inward projecting studs e shown in Figures 4 and 5
of the drawing. Vertically extending connecting rods K5 are pivotally attached
to the levers or arms K adjacent to their points of connection with the links K³
and said connecting rods are pivoted at their lower ends to the outer ends of
arms K which are rigidly attached at their rear ends to a rock shaft e³ rota-
tively mounted between the frame members E as seen in Figure 5 of the draw-
ing. Said rock shaft is provided between the arms with a forwardly ex-

page_text: tending arm K, to the outer end of which is attached a downwardly extending
connecting rod K8 which is in turn pivotally attached at its lower end between
the ends of a treadle arm or lever K³. Said treadle arm is pivoted between
its ends upon a transverse shaft et extending between the lower transverse mem-
bers E of the frame. The outer end of said treadle arms is provided with a
foot rest Ko which is adapted to be engaged by the foot of the operator when
it is desired to actuate the upper roller. As before stated, the upper roller will
normally be held raised as shown in Figure 11, in which position sheets of
paper may be readily inserted beneath it and in position for crimping. When
it is desired to have the surface thereof co-act with the surface of the roller K'
to feed the paper between the same, said roller K will be lowered by depressing
the outer or free end of the treadle arm K³ in an obvious manner. Any suitable
means may be employed to maintain the roller K in its normally elevated posi-
tion. A preferred form of such means will be hereinafter described.
Means for actuating said rollers to feed the paper between the same are pro-
vided as follows: The upper roller K is provided on one end thereof, at the
left hand as herein shown, outside of frame E2 with a ratchet pinion L (Figures 3
and 5), said wheel being rigidly secured to the shaft of the roller. L' designates
a radially extending arm pivotally mounted on the shaft of said roller K, out-
side of said ratchet wheel L. Said arm L¹ is provided adjacent to its outer end
with a gravity pawl L2 adapted to engage the teeth of the ratchet wheel L.
Said pawl is herein shown as directed inwardly from the arm L' and adapted to
engage the teeth of the wheel L between the arm and the tucker blade D D¹
With this construction when the arm L is oscillated toward the knives, the pawl
will act to turn the ratchet wheel and attached roller K inwardly and thus move
the sheet of paper between said roller K and the lower roller K' outwardly away
from the tucker blade.
The means for automatically oscillating said roller K as the sheet is crimped
is as follows: L³ designates an actuating bar which is pivotally engaged at
one end with the arm L and has endwise sliding engagement at its opposite end
with the pillow block E of the frame. In the present instance, said bar L³
is provided on its end thereof adjacent said block with elongated slot which is
adapted to engage an outwardly extending stud ein said block, said connection
being such that the bar L³ may have free longitudinal movement thereon. Upon
the shaft G inside of the gear wheel G2 is formed a cam so arranged as to
engage the adjacent end of the actuating bar L2 once during each rotation of the
shaft, and which acts to move said bar outwardly and to thereby oscillate the
outer end of the arm L', which is connected with the bar, away from the tucker
blade D D¹. To the outer end of the arm L' is attached a spiral contractile
spring L the opposite end of which is attached to an outwardly projecting
stud on the pillow block E7 of the frame. Said spring acts to restore the outer
end of the arm L¹ to a vertical position after it has been oscillated by engagement
of the cam with the inner end of the actuating bar as herein described; and by
reason of the engagement of the pawl with the ratchet wheel as shown, the
spring will act to turn said ratchet wheel and attached roller K inwardly in the
manner before described. Any suitable means may be employed for the attach-
ing the outer end of the connecting rod L³ with the radial arm L. As herein
shown, said arm is provided on its outer face with the T slot within which
is adapted to rest and slide a correspondingly shaped pivot stud with which
the outer end of the actuating bar L3 is pivotally engaged. Said stud will be
adjustably secured to the arm L¹ in any suitable manner. When the stud is
moved upwardly or downwardly in the slot 7 the throw of the arm L¹ will be
decreased or increased and the length of the feed of the paper between the
rollers K K¹ correspondingly changed.
The ends of the shaft opposite the parts just described are operatively con-
nected together, by means whereby the upper roller is given a positive rotary
motion in the desired direction and at the desired speed. The details of such

page_text: mechanism are shown in Figures 2 and 11. In said figures designates a gear
wheel mounted on the shaft of the roller K and a gear wheel mounted on the
shaft of the roller K¹. Said wheels are adapted to mesh with each other when
the roller K is in its lower position, but are moved out of contact with each
other when said roller is lifted. Said wheels are maintained in constant opera-
tive relations by means of two intermediate gears mounted on short
shafts which latter are mounted between side plates or links 10. Said
gears mesh with each other and with the gears and are connected with
the latter by means of side plates or links mounted at their opposite ends
upon the shafts 18 and the shafts of the rollers K K¹. The upper link "
or that engaging the shaft of the roller K is pivotally mounted upon the shaft 19
so that the outer end thereof may swing upwardly to permit upward movement
of the attached roller K.
The machine thus far described is operative to crimp sheets of paper in the
manner herein before set forth. The tucker blades will each act to start the
fold or crease in the paper once in each direction during each revolution of the
shaft G, the movable crimping jaw will act to crimp each fold, the clamping
jaw will be raised once during each revolution of the shaft G and said shaft
will act through the cam surface g² to actuate the rollers KK to advance the
sheet between the jaws. When the clamping jaw B descends upon the jaw A
after a crease or fold has been formed and the sheet is fed along for the next
fold or crease, the sheet is flattened out along the line of the crease or bend
just made. This is repeated as to each crease or fold except the last one, and
the sheet is taken out of the machine, therefore, with a practically smooth sur-
face although having a plurality of parallel creases or folds. I may also time
the forward movement of the roller K so as to cause the sheet to pass out of the
machine between the roller K and K whereby the sheet will be flattened out by
said rollers. The sheet of paper in Figure 12 is shown as provided with ten
creases or folds and the machine herein shown will be considered as designed
for crimping a sheet in such manner in one continuous operation thereof. The
machine may, of course, be set to produce any greater or less number of folds
or creases desired, but, in any case, it is desirable that the machine may be
automatically stopped when the predetermined number of creases or folds have
been produced. To accomplish this result mechanism is provided as follows:
M³ designate a pulley mounted rigidly on the shaft M, and as herein shown,
on the end thereof adjacent to the gear wheel M¹. N designates a friction break
comprising two jaw's N¹ N' which are divergently curved at one end thereof to
embrace the pulley M³ as more clearly shown in Figure 5 of the drawing. Said
arms are pivoted at their lower ends upon a stud E¹³ extending inwardly from
the frame E adjacent to the pulley M³ and are adapted to oscillate toward and
from each other in a vertical plane. The parts of said arms adjacent to the
pivotal point of connection with the stud N are provided with an aperture which
extends from front to rear of the machine and within said aperture is arranged
a clamping bolt or pin n provided on one end with a shoulder, herein shown as
formed by locking nuts n¹ and is engaged at its outer end with a lever N2 which
is arranged with its fulcrum on the arm N1 of the clutch opposite that with which
nuts are engaged. Said lever acts in connection with the pin n when the
lower end thereof is oscillated away from the pulley, to draw the arm of the
brake together and clamp them upon the pulley N. The lower end of the
jaws are provided on opposite sides thereof with bearing blocks n2, which
may be made integral therewith or not as desired, and with which the nuts n¹
and lever N2 are engaged. Said lever is herein shown as provided with an
inturned end portion the extreme inner end of which engages the adjacent
bearing block 2 and forms the fulcrum of the lever. With this construction.
the point of fulcrum on the bearing block n² moves downwardly as the lower end
of the lever is moved outwardly away from the pulley so that the point of appli-
cation of power of the clamping pin n remains in the same horizontal plane..

page_text: The upper or bent end portion of the lever N is bifurcated, and between the
arms thereof the outer end of the clamping pin n rests and is secured therein
by means of a pivot bolt π. N³ designates a spring which engages at one end
the lower end of the lever N2 and is attached at its outer end to the frame by
means of which the lever is returned to its normal non-clamping position when
released.
O designates a shaft rotatively mounted below the shaft M and slightly in
the rear thereof. Said shaft is provided on its outer end with a large gear
wheel O which intermeshes with and receives motion from a small gear pinion I'
mounted upon a sleeve P which rotatively mounted upon a stud 13 extending
outwardly from the frame E above and in front of the shaft O; said sleeve I'
being provided outside of the wheel P with a second gear wheel P³ which inter-
meshes with and receives motion from a gear wheel M on the outer end of the
main shaft M. It will thus be seen that the connection between said main
shaft M and the shaft is such that shaft will be caused to rotate very slowly
with relation to the main shaft. Said shaft O is provided adjacent to the lever N
with a sleeve 02 on which is formed a cam o, as shown in Figure 5 of the drawing.
Said cam, as herein shown, rotates from right to left and engages the lever N
to gradually force the lower end thereof rearwardly and thereby tighten the
brake N upon the pulley M³ which gradually stops the rotation of the shaft M
and the movements of the parts of the machine connected therewith. The
shaft carrying the cam C rotates very slowly with relation to the driving
shaft M and said cam acts to gradually retard the movement of the shaft and
the parts connected therewith. Said parts are so arranged that when the cam
is exerting its greatest power upon the lever, or is in that position in which a
line passing through the same and the center of the shaft extends at right angles
to the levers N2, such lever will act with such force upon the brake N as to
positively stop the movement of the shaft M and the parts operatively connected
therewith.
The shaft M is provided on its outer end adjacent to the driving pulley M²
with a friction clutch M³ by means of which said pulley M² is connected with the
shaft M in the usual manner. As the shaft M is stopped gradually by the fric-
tion brake N, the clutch is so mounted upon the shaft as to permit it to slip
somewhat thereon when said brake N is set upon the pulley 3. Said clutch
is adapted to be disconnected from the shaft at a time slightly in advance of
the moment when the lever N2 is exerting its greatest power upon the brake N
to stop said pulley M³ and shaft M connected therewith. Said clutch is actuated
by means of a lever Q which is engaged at one end with an annular groove in
the clutch and is pivoted between its ends upon a bracket A¹ extending out-
wardly from the frame of the machine. The lever Q is engaged at its lower
end with a spring Q which is attached to the frame of the machine and which
acts through said lever to normally hold said clutch out of engagement with the
pulley M². Said clutch is held positively in its operative position or that in
which it acts to connect the pulley M2 with the shaft M by means of an actuating
bar Q2 connected with the lever below its point of pivotal attachment with the
bracket Q and adapted to be engaged at its opposite end with a suitable guide
surface upon the shaft O. Said guide surface is so formed as to hold the bar
and connecting lever in their outermost position during the greater part of the
rotation of said shaft but at a given time in the rotation thereof it permits
said bar to move endwise toward the guide surface and thereby allows the
lever Q, under the action of the spring Q, to be oscillated to move the clutch M³
out of engagement with the pulley M². Said guide surface in this instance
consists of a segment mounted upon the shaft adjacent to the cam sleeve O.
Said segment as herein shown as made in the form of a pulley S provided in its
periphery with a recess S¹ within which is adapted to enter at a given time in
the rotation thereof the adjacent end of the actuating bar Q3. The cam o of
the sleeve O and the recess S¹ in the pulley are so arranged upon the shaft

page_text: that said recess will be moved into the plane of the bar A² just before the cam o
is exerting its most effective power through the lever N2 upon the friction
brake N, so that at the instant the actuating bar enters the said recess of the
pulley and permits the lever to oscillate and actuate the clutch to disconnect
the pulley M from the shaft M, the brake mechanism will act to positively stop
the movement of the shaft M. and the parts of the machinery operatively con-
nected therewith. The recess is made slightly wider than the thickness of
said actuating bar Q2, and the peripheral speed of the pulley S is such that the
brake will act to entirely stop the machine before the bar Q2 comes in contact
with the sides of the recess. With this arrangement no strain whatever comes
upon said bar when stopping the machine. The inner end of the bar Q2 is pro-
vided with an anti-friction roller Q by which friction between the same and
the pulley is obviated in the rotation of said pulley.
The clutch will be held in its retracted position by the spring Q3 and will be
moved inwardly against the action of said springs to connect the pulley with
the shaft when the actuating bar Q2 is disengaged from the recess in the pulley S.
Said actuating bar is herein shown as connected with the rear end of the treadle
armı K in such manner that when the forward end of said arm is depressed,
the bar will be withdrawn from the recess St and the clutch move to connect the
pulley with the shaft M¹ as before described. The actuating bar Q2 is connected
with the rear end of the treadle arm K by means of a bell crank lever R pivoted
at its angle upon a bracket R¹ which projects inwardly from the frame E. The
arm of said bell crank lever adjacent to the treadle arm is operatively connected
therewith by means of a connecting link R2 and the opposite arm of the lever
is operatively connected with the bar Q2 as shown in Figure 4. Said bell crank
lever R is so arranged that when the actuating bar connected therewith is in
its innermost position or engaged with the recess S' of the pulley S, the rear end
of the treadle arm K will be depressed and the outer end thereof elevated, at
which time, as before stated, the clutch will be disengaged from the pulley M².
When, therefore, the forward end of the treadle arm K is depressed, it will act
through the connecting link R2 and bell crank lever R to withdraw the actuating
bar from engagement with the pulley S and to oscillate to lever Q to move the
clutch into engagement with the driving pulley. With this engagement, it will
be seen that the spring Q3 tends through the connection described to normally
depress the rear end of the treadle arm K and raise the forward end thereof;
which will, through its connections with the roller K act to raise said roller away
from the roller K¹. Said treadle arm, therefore, serves the double purpose of
actuating the rollers K to move it into its operative position with the roller K¹
and to operate the mechanism by which power is connected with the machine.
As the movement required to lower the roller K is less than that necessary to
move the clutch M³, through the connection with the lever, into the operative
position, the lower end of the connecting rod K8 is shown as provided with a
slot within which the pivot bolt rests, by means of which said lever K
may have vertical movement, with relation to the connecting rod K8. When
the clutch M is disconnected from the power pulley M², as before stated and the
free end of the lever is in its raised position, the bolt will engage the upper
end of the slot . Said slot, is therefore, allows the arm K to be depressed
some distance when the clutch is being moved into its operative position, before
the connections between the treadle arm and roller K are actuated to move the
same roller downwardly. Said connecting rod is provided in its portion contain-
ing the slot with an adjusting plate by which the length of the slot engaged
by the pivot bolt may be varied as desired to correspond with varying sizes
of the roller K and other modifying conditions. When the outer or free end
of the treadle. arm K' is depressed to connect the friction clutch M with the
pulley M², said action will withdraw the actuating bar Q2 from the recess S¹
of the pulley and the machine will be free to operate under the action of the
applied power until the pulley has completed another rotation, when the brake

page_text: will operate to stop the machine, at which time the bar will enter the recess in
said pulley and permit the lever Q to oscillate to disengage the clutch from the
pulley Me
The construction and arrangement of the operative parts of the machine is
such that the shaft G will stop with the cam thereon in engagement with the
adjacent end of the lever I, by means of which the clamping jaws B B¹ will
always be in their raised position when the machine is not in operation, and
the sheets of paper may, therefore, be readily inserted into and withdrawn
therefrom.
The operation of the machine will be readily understood from the foregoing
description: As stated, when the machine is not in operation, the clamping
jaws BB and the roller K are in their upper position and a sheet of paper may
be readily inserted thereunder, the sheet of paper is moved inwardly until it
engages the stops B³ which have previously been adjusted to produce the width
of margin desired. The operator now depresses the forward end of the treadle
lever K which lowers the roller K and throws the machine in operation by with-
drawing the actuating bar Q2 from engagement with the pulley S connecting M³
with the shaft M. The instant the machine begins its operation, the cam g
leaves the lever I and the clamping jaws are moved by the action of their actu-
ating springs to their lower or clamping position. The tucker blade is now
actuated by the means described and the crimping jaws move inwardly to crimp
the folds or creases as described in connection with said constructions.. The
rollers are actuated at each rotation of the shaft G to advance the paper so as
to prevent a fresh surface for the next succeeding fold or crease. In the machine
described, the shaft G will rotate five times during one rotation of the shaft O
while the shaft H will move through ten rotations during such time. If the
larger or smaller number of folds or creases are desired in the sheet, the relative
speeds of the shafts H and G to the shaft will be changed accordingly. When
the last crimp has been made in the sheet, the brake N will operate to stop the
machine, the bar Q will be thrown into engagement with the recess S of the
pulley S and the clutch M disengaged from the pulley M2 when the machine will
be stopped. The sheet of paper will now be withdrawn and a new one inserted
when the operation will be repeated. The operation of the machine after the
paper has been inserted and the lever K depressed is, as will be seen, entirely
automatic and requires no supervision from the operator until the sheet is ready
to be withdrawn and a new one inserted therein.
