Improvements in Machinery or Apparatus for Manufacturing Parts
of Boxes or other Articles of Paper, Straw Board, Wood, or
other Material.
I MARK DEAN KNOWLTON of 155 Michigan Avenue, Chicago, Cook County, in the
State of Illinois one of the United States of America, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to an improved machine for making the joints in the
manufacture of boxes or other articles of paper, straw-board, wood veneer or similar
material, and more particularly adapted for use in the manufacture of paper or straw-
board boxes for the purpose of "setting up or jointing the cut edges of the paper,
دو
straw-board or wood veneer box blank at the corners of the box. The invention
relates more particularly to a machine organised for applying to the edges to be joined
a strip or piece of paper or other material which is caused to adhere to the parts by
paste glue or other adhesive substance.
A machine embodying my invention has clamping dies for pressing or forcing
jointing strips against or in contact with the edges of the parts to be joined after
paste, glue or other adhesive substance has been placed between the strip and the .
surfaces to which it is to be applied, together with means for guiding or directing to
or between said dies a paper strip from which the individual jointing strips are
severed.
As far as this is concerned the paper strip may be fed forward to the dies either
by hand or otherwise. The machine has an automatically acting feeding device, by

page_text: which the paper strip is fed forward between the dies each time the latter are actuated
for clamping the strip against the parts to be joined. The machine generally has an
automatically acting cutting device for severing the jointing strips or pieces from the
continuous strip and for applying adhesive substance to said strip.
The devices for applying adhesive substance are not essential in a machine embracing
the main features of construction inasmuch as the strips may be previously coated
with adhesive substance, which is allowed to dry, and is moistened by steam or other-
wise shortly before it is applied to the parts to be joined or paste or glue may be
applied by hand to the jointing strips or to the parts to be joined. The employment
of means for continuously applying paste or glue to the strip as it is fed to the
clamping dies and a machine embracing devices for this purpose is new, as are the
paste-applying devices. The machine may be employed for joining the edges of
paper or straw-board articles, cither when the parts to be joined are in the same plane
or when they are arranged at an angle with each other. For joining the sides of
straw-board boxes the dies may be made one concave and the other convex and with
flat faces arranged at an angle with each other or sides of box.
One of the clamping dies may be constructed to reciprocate in applying the jointing
strips, while the other remains immovable, and the paper strip severed by a knife or
cutter upon the machine frame acting in conjunction with a cutting edge of or upon
the moveable die.
The non-reciprocating die or anvil block may be bodily movable or adjustable
with relation to the machine frame and the stationary cutter supported thereon
and said non-reciprocating die or anvil block connected with the actuating devices
and the paper fed forward so that the extent of the forward movement of the paper
strip will be changed, by moving the said adjustable die, to correspond with the width
of the sides of the box to be joined by the strip, so that a jointing strip of the right
length will in every instance be applied to the box.
The machine is adapted to be actuated by a foot lever, or by power or by the
operator acting through other means than the foot lever.
The main frame of the machine may be formed embracing a horizontal bed-plate,
a vertical part or standard, at one end of the bed-plate, and a flat vertical side-plato
or web, arranged at one side of the bed plate and connected at its margin with
the standard. To the bed-plate are attached legs by which the machine is
supported.
Upon the frame the several operative parts of the machine are mounted or sustained.
A non-reciprocating die or stationary anvil block, say a bar or rod is arranged hori-
zontally and supported in the standard somewhat above the bed-plate. The block
extends at its end through the exterior vertical face of the frame standard and the
projecting part forms the working surface of the die or anvil. The anvil block is
fitted to slide longitudinally within its seat or bearing in the standard so that its end
portion may be extended a greater or less distance from the face of the said standard.
A simple and convenient construction of the anvil block is made semi-circular upon
its under face and provided. at its outer end with flat working faces arranged at right
angles with each other with their meeting edges upward. "The anvil block may be
held or clamped in place in any suitable manner the means for clamping consisting
of a clamp bar resting at its upper end against a laterally protecting arm of the
standard and bearing at its inner end upon a flat surface at the top of the inner
portion of the anvil block. The clamp bar is held against and over the anvil block
by a set-screw passing through the clamp bar and entering the standard near the anvil
block. A moveable part or reciprocating die of the clamping or pressing device
arranged vertically over the end of the anvil block which projects from the face of
the standard and being provided with a "V" shaped notch or recess in its under
surface forming the working face of the die to engage with the oblique surfaces of
the anvil block. The die is attached to a vertically movable slide mounted in guides
upon the standard.
Said reciprocating die acts in conjunction with a stationary knife or cutter to sever
the separate jointing strips from the long or continuous strip fed to the machine.

page_text: Said stationary knife or cutter is so located over the stationary die-block that the said
strip is fed or guided over said die-block as the strip is advanced between the dies.
The cutter may be held or supported in a removeable plate bolted to the frame
standard and provided with an opening or passage through which the strip passes
to the dies.
The slide which supports the die may be moved vertically for actuating the movable
die by a heavy and strong bell-crank lever mounted upon a pivot inserted through
lugs or bearings located at the upper end of the standard at the inner face thereof.
The bell-crank lever is provided with a short horizontal arm which engages a
recess in the upper part of the slide said arm is provided with a flat spring arranged
to bear upward against the upper wall of the opening to take up lost motion in
the parts.
Said bell-crank lever is provided with a second arm which extends obliquely down-
ward to a point near the bed-plate. A foot lever is pivotted at its upper end to the
machine frame by means of a pivot pin arranged near the lower end of the standard.
To the upper end of said foot lever is attached a rearwardly extending rigid arm
which is connected with the lower end of the lever arm of the bell-crank lover by
means of connecting plates. When the lower end of the foot lever is thrown back-
wardly the lower end of the lever is thrown upwardly and inwardly and the slide and
upper die thereby depressed. When the foot lever is thrown forward on the contrary
the die is elevated. A bar attached to the foot lever sliding in a bracket upon the bed
plate and provided with a head may be employed to limit the backward motion of the
foot lever.
The continuous strip of paper to be fed to the machine for making the joints, is
mounted upon a reel sustained upon an arm attached to the frame. A folder acts
upon said strip after the latter leaves the reel to double or crease the same in its middle
so that it will take and maintain a "V" shape at the time it is introduced between the
clamping-dies.
A pasting roller the periphery of which is made of "V" shape to fit within the
creased or folded lower surface of the strip and a pressure roller for holding the
strip in contact with the said pasting roller is provided.
The paper strip is carried forward or fed to the clamping dies after leaving the
pasting roller by feeding devices acting to give an intermittent forward motion to the
strip whereby the end of the latter is carried rapidly. or quickly forward between
the clamping-dies and over the margin of the box sides placed over the stationary die
and remains immovable while the dies are being brought together and the jointing
piece to be attached to the box is being severed from the continuous strip.
The feeding device comprises a reciprocating gripper which engages and carries
forward the paper strip in its forward movement and becomes released from the strip
at the limit of its forward movement, so as to move backwardly without producing.
any corresponding movement in the strip. The construction in the feeding device
and means for guiding the paper strip to the same and from said feeding device to the
clamping dies embodies an L shaped guide plate which serves to guide the paper strip
to the clamping-dies and upon which the main operative parts of the feeding device
are sustained.
Said plate is provided with a vertical flange at one of its edges which flange is
provided with a longitudinal guide-slot in which the reciprocating gripper is held
and guided. Said guide-plate is also preferably provided with an arm or bracket
by which it is secured to the machine frame. The main part of the guide-plate is
beneath the path of the paper-strip, so that the said strip passes longitudinally over
said plate parallel with the guide slot thereof.
The gripping device comprises a sliding plate arranged vertically against the
vertical plate and held in place by means of another plate located at the opposite
or exterior face of the said vertical plate and connected with the L plate
through a slot.
A filling piece is desirably attached to the plate within the slot. The lower jaw
of the gripping device is arranged centrally beneath the path of the paper strip,

page_text: and provided with a sharp or narrow-bearing edge to engage the inner surface of
the strip at the upper part or crease of the same. The said jaw of the gripper is
connected with the lower edge of the sliding plato by a horizontal arm or plate
adjacent to the L plate and with its upper surface a sufficient distance below the edge
of the lower gripper to avoid contact with the corner margin of the folded or
"V" shaped strip passing over it. The sliding plate the horizontal plate and the
gripper jaw may be formed or bent from a single piece of metal. The upper or
moveable gripper jaw may be arranged above the lower jaw thereof and made
vertically moveable so that it may be either engaged with or lifted free from the said
lower jaw.
The moveable gripping jaw may be formed by or upon the end of the horizontal
lever which is mounted upon a pivot pin affixed in the sliding plate said lever being
arranged horizontally and its pivot being arranged to overhang the path of the
paper strip.
The working face of the said gripper-jaw may be a separate piece of hard metal
serrated or roughened to more positively engage the strip. An arm for actuating the
gripper arm is provided attached to and extended upwardly from that arm and having
at its upper end a horizontal crank pin.
The reciprocating part or plate carrying the gripping jaws, and the jaws themselves
'may be separately moved by suitable actuating devices. For simplicity the
reciprocating gripper-carrying plate and the gripper may be driven by actuating
devices engaged with the upper end of the lever arm alone. For this purpose
frictional engagement may be provided between the said plate and its guide, tending
to retard the movement of the plate so that when pressure is applied to the upper end
of the arm in a direction to carry the said upper end of the arm forward the gripper
arm will first be. depressed after which a continued forward pressure upon the upper
end of the former arm will carry the sliding plate and gripper jaws bodily
forward.
Similarly when the pressure is applied to the upper end of the gripper actuating
lever to move the same backwardly, the jaws will first be opened and the entire
gripping device will then be moved bodily backward.
Any one of a great number of well known devices may be employed for producing
frictional engagement between the sliding plate and the guide plate say I provide a
flat spring resting at its middle against the plate and two screws inserted through the
ends of said spring and through smooth openings in the said plate and having screw-
threaded engagement with the sliding plate. The flat spring holds the plates in
forcible contact with the opposite sides of the guide plate and by turning the screws
the pressure of the spring may be adjusted.
Devices for actuating the feeding mechanism are as follows:-A rocking lever
which is pivotally supported upon a shaft mounted in the flange or web of the machine
frame at a point near the end of the machine. Adjacent to its pivotal point, the rock
lever is provided with a rigid arm with which arm is engaged a bar, the opposite or
lower end of which is pivotted to the foot lever. The rocking lever is connected with
the lever arm of the feeding device by means of a connecting rod engaged with a pivot
upon the lever and with the pivot pin of that said arm.
The upper end of the bar is not pivotally connected with the arm of the rock lever
but said arm is provided with a stud which engages a notch in the upper end of the
said arm and said lever is held in position for the engagement of said notch with the
said stud by means of a supporting surface or abutment upon the machine frame, say
by an antifriction roller. The rock lever is held at the rearward limit of its movement
by a suitably applied spring so that the forward movement only of the gripping device
is given by the action of the bar and foot lever the rearward or return movement of
the gripping device being afforded by said spring.
The shaft of the rock lever may be rigidly attached to the arm and extend through
and bear in the frame plate or web and extend outside of the web and be provided at
its outer end with a collar attached to one end of a spirally coiled spring the opposite
end of which is attached to the frame.

page_text: Said spring tends to hold the rocking lever normally at the rearward limit of its
movement, and act to promptly return the gripping devices to their starting point after
the bar has been drawn downwardly or retracted.
The stnd of the said arm is so located with reference to the bar that said stud will
swing forward out of the notch of said arm after the arm has been lifted a short
distance and when the rock lever has been swung forward a sufficient distance to give
the movement in the gripping devices necessary for properly feeding the paper strip.
The said bar may be held from being carried forward away from the roller by means
of a roller or otherwise.
After the notch of the bar is released from the stud the upward movement of the
bar is continued as the foot lever is thrust backward, without producing any movement
in the gripping devices, until the clamping dies have been brought together and the
necessary pressure put upon the parts to be joined and the jointing strip.
For applying jointing strips in the making of boxes of different sizes it is obviously
desirable that the distance to which the strip is fed forward past the cutting or severing
devices at each advance movement of the feeding mechanism should be capable of
variation in order that the length of the strip used upon the box may correspond with
the depth of the same. In connection with the stationary die or anvil block which
is moveable bodily to afford a greater or less distance between the cutting off
mechanism and the end of the block, I have provided a connecting mechanism
between such movable anvil block and the parts by which the feeding devices are
actuated, whereby the movement of the block a certain distance will produce a
corresponding change in the throw of the gripping jaws, whereby the length of the
strip fed forward at each reciprocation of the gripping jaws will correspond
approximately with the length of the exposed part of the anvil block and the joint to
be made.
This may be constructed as follows: The pivot pin which connects the rocking-lever
with the connecting rod instead of being immovably secured in the rock lever is
adapted for longitudinal movement thereon. It may be mounted upon a sliding block
engaged with a guide groove in the said lever. A bell crank lever which mounted
upon a pivot located beneath the inner end of the anvil block or bar is provided with
an upwardly extending arm having engagement with the block and with a horizontal
arm, the free end of which is connected with the said sliding block by means of a
connecting rod. The connection between the bell-crank lever and the anvil block
may be formed by means of a plate attached to the side of the said anvil block
and provided with a vertical groove which engages a pivot pin in the upper end of
the vertical arm of said bell-crank lever. When the said anvil block connected with
the pivot pin of the rocking lever is thrust inwardly said pivot pin will be moved
upwardly thereby giving a greater throw to the said pivot pin and increasing the
throw of the gripping devices. When, on the contrary, the anvil block. is moved
inwardly the pivot is moved inwardly upon the rocking lever thereby decreasing the
throw of said pin and giving a less movement in the gripping devices and decreasing
the distance through which the paper strip is fed forward at each action of the feeding
mechanism.
shaped
For guiding the paper strip on the pasting roller to the gripping devices and from
said gripping devices to the clamping dies is provided at the rear end of the guide
plate is located a rigid plate arranged at right angles with said guide plate and
extending over the path of the paper strip. Said plate is provided in its lower edge
with a
"V" shaped notch to engage the upper surface of the strip, Upon
the end of the plate opposite the said guide plate is located a
guide bar which also extends over the strip and engages the upper surface thereof.
Along the upper surface of the L plate at the central line of the paper strip
is located a longitudinal guide strip consisting of a narrow strand or filament
of metal, the upper margin of which is arranged in approximately the same
horizontal plane as the upper end of the lower gripping jaw and which is construted
to engage the under surface of the paper strip within the seam or crease thereof.
The purpose of this said guide strip is to hold the paper strip accurately in position

page_text: with relation to the gripping devices, so that the crease in the paper strip will come
exactly over the lower gripping jaw and thus pervent a distortion of the strip when
the same is gripped between the jaws. The said strip may be supported by being
attached to a plate which is secured to the L plate at the end of the latter at which
the paper strip enters the guiding devices. At its opposite or forward end the guide
strip is unsupported the plate being cut away beneath the strip at this point so as
to form an opening or recess within which the upper edge or corner of the working
face of the anvil may enter when said anvil is thrust inwardly for operating upon
shallow boxes or covers.
The said guide strip, may, however, be sustained or held from lateral move-
ment by engagement with the lower gripping jaw at one side of which said bar
passes.
In a preferred construction in these parts the guide strip is bevelled at one side
only to give it a sharp or narrow edge located at that face of the strip which is in
contact with the gripping jaw, while the said jaw has a similar shape, being made
flat at its side in contact with the guide strip and bevelled at its opposite or outer
side. By this construction the upper edges of hoth the strip and gripping jaw may
be made to engage the crease of the paper strip while at the same time the said
gripping jaw may be reciprocated without interfering with the guide strip. If
found necessary or desirable a small lug or projection may be placed upon the arm
in position to engage the inner face of the guide strip thereby forming with the
jaw a notch in which the said guide strip is held and guided. The said notch will,
however, be made slightly deeper than the thickness of the guide strip, so that the
upper gripping jaw will act against the lower jaw and will not press against the
upper edge of the guide strip.
Two guide rods located above the guide plate one at each side of the guide-strip
at suitable distances apart engage the upper surface of the paper strip near the
lateral margins thereof, keeping the strip accurately in position with relation to
the gripping jaws of the feeding mechanism, and preventing the sides of the folded
or creased paper strip from bending or curling up, on account of the moisture in the
paste or glue applied thereto. These guide bars may be attached to or supported from
the plate in any desired manner.
At its end nearest the clamping dies the L plate is provided with a "V" shaped
extension adapted to enter the opening of the plate by which the stationary cutter
is directly supported. Said extension serves to guide the paper strip until the latter
reaches the said cutter. The projection is provided at its top with a vertical flange
the upper edge of which rests against the top of the said opening.
The sides of the said projection together with the flange serve to hold the ends of
the guide devices accurately in position with reference to the knife and the clamping
dies by their engagement with the walls of said opening.
I have found that in the use of suitable rollers for applying paste to the paper
strip, that when the said strip is carried or moved rapidly forwardly by the action
of the feeding mechanism the impetus acquired by the paste rollers as they are turned
by the paper is liable to cause the said rollers to continue to turn in a manner to
thrust the paper forward, after the gripping jaws have completed their forward move-
ment. To avoid this result-1 so construct the upper roller that it may be lifted to
free it from the lower roller and I provide means whereby the upper roller will be
automatically lifted free from the lower roller at the moment forward movement of
the gripping jaws is terminated. When the parts are thus constructed the paper
strip is released from the paste rollers before the latter have an opportunity to act
upon the strip in a manner to carry it forward and the upper feed roller may be
lifted or moved by any upwardly moving part of the machine acting against the feed
roller support at the proper time; for instance, the upper roller is mounted upon a
pivot pin having bearings at its opposite ends in two parallel arms which are rigidly
connected with each other and are mounted upon a rigid pivot pin affixed in the frame
plate. Upon the end of one of the arms is formed or attached an arm or striker
located in position to engage the stud of the rocking lever when the said stud has

page_text: nearly reached the upward limit of its movement. When the said lever is actuated
by the notched bar therefore, the supporting arms and the roller will be lifted at the
moment the feeding device reaches the forward limit of its movement and said roller
will be supported free from the paper strip until the foot lever is swung rearwardly
and the bar retracted preparatory to another and succeeding operation of the machine.
The lower paste roller enters a tank or receptacle containing paste or other adhesive
substance so as to become coated upon its margin a scraper arranged to fit against
the "V"shaped periphery of the said feed roller removes the surplus.
The cutter or sheer blade employed to sever that part of the jointing strip applied
to the box walls from the main or continuous part of the strip, may act in connection
with the cutting edge formed at the rear surface of the movable clamping die
as the movable die descends toward the work. Any separate knife or cutter on the
movable die is rendered unnecessary by making the rear face and working surface
of the movable die of hardened steel.
The stationary knife or cutter is made preferably of thin or sheet metal and of
inverted "V" shape and is secured to the cutter holding plate by screws.
A plate
secured to the holding plate above said cutter aids in holding the same in place. Said.
attached plate is provided with an opening through which the strip passes over the
knife. The forward edge of the cutter forms the cutting edge thereof and the cutter
is held up to its work by screws.
The moveable die may be constructed in any suitable or preferred manner to afford
a suitable cutting edge at its rear surface. In the particular construction herein
illustrated the working surface of the die is formed in a cylindric block of hardened
steel the lower surface of which block is provided with a "V" shaped notch corre-
sponding in form with opposing surface of the die block. The rear or inner end
surface of the said hardened block rests in contact with the edge of the cutter so that
the square edges of the notch act in connection with the said cutter to sever the
paper strip the block is held within the head of the die by splitting the latter
vertically and inserting one or more clamp screws for holding the split parts
together.
A screw inserted in the head and overlapping the die block serves to hold the guide
block from being thrust end wise out of the head, and to adjust said block with
reference to the stationary cutter.
In the operation of the machine the operator sits or stands in front of the same and
places the corners of the box blank, split and scored, upon the upper surface of the
anvil below the movable die, the sides of the box being bent or held approximately at
right angles with the bottom when the blank is placed upon the anvil block. When the
corner of the. blank is thus held upon the block the foot lever is actuated, with the
result of quickly thrusting forward the end of the strip over the edges of the blank
and then depressing the upper die to sever the strip and forcing it into contact with
the surface of the blank. The folder comprises a curved plate which is bent into
tubular shape, with the side walls at some distance apart at their rear ends but brought
together or parallel with each other at their forward ends, so as to gradually bring
together the margins of the strip, thereby bending the paper strip into "U" shape
and to then fold or crease the strip as it emerges from the folder.
The main features of my invention may obviously be carried out by a mechanism
differing materially in its details from the particular details given.

Improvements in Machinery or Apparatus for Manufacturing Parts
of Boxes or other Articles of Paper, Strawboard, Wood, or
other Material.
I, MARK DEAN KNOWLTON of 155 Michigan Avenue, Chicago, Cook County,
in the State of Illinois one of the United States of America, Manufacturer
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:
دو
This invention relates to an improved machine for making the joints in the manu
facture of boxes or other articles of paper, straw board, wood veneer or similar
material, and more particularly adapted for use in the manufacture of paper or straw-
board boxes for the purpose of "setting up or jointing the cut edges of the paper,
straw-board or wood veneer box-blank at the corners of the box. The invention
relates more particularly to a machine organised for applying to the edges to be
joined a strip or piece of paper or other material, which is caused to adhere to the
parts by paste, glue or other adhesive substance. The invention consists in the
matters hereinafter described and pointed out in the appended claims.
A machine embodying my invention embraces, as its main or essential features,
clamping dies for pressing or forcing jointing strips against or in contact with the
edges of the parts to be joined, after paste, glue or other adhesive substance has been
placed between the strip and the surfaces to which it is to be applied, together with
means for guiding or direction to or between said dies a paper strip from which the
individual jointing strips are severed. As far as this main feature of the invention is
concerned, the paper strip may be fed forward to the dies either by hand or other-
wise. The machine herein shown, embraces, as a separate and further improvement,
an automatically acting feeding device, by which the paper strip is fed forward
between the dies each time the latter are actuated for clamping the strip against the
parts to be joined. The particular machine herein shown embraces furthermore as an
additional. improvement an automatically acting cutting device for severing the
jointing strips or pieces from the continuous strip and for applying adhesive substance
to said strip. The devices for applying adhesive substance are not essential in a
machine embracing the main features of construction above illustrated, inasmuch as
the strips may be previously coated with adhesive substance, which is allowed to dry,
and is moistened by steam or otherwise, shortly before it is applied to the parts to be
joined, or paste or glue may be applied by hand to the jointing strips or to the parts
to be joined. The employment of means for continuously applying paste or glue to
the strip as it is fed to the clamping dies is for several reasons preferred, and a
machine embracing devices for this purpose is herein claimed as new, as are certain
parts of the machine relating to the paste-applying devices. The machine may be

page_text: the die or anvil. The said anvil block B is fitted to slide longitudinally within its
seat or bearing in the standard A' so that its end portion may be extended a greater
or less distance from the face of the said standard. In a simple and convenient
construction of the anvil block herein shown the latter is made semi-circular upon
its under face and provided at its outer end with flat working faces bb arranged
at right angles with each other with their meeting edges upward. The anvil block
may be held or clamped in place in any suitable manner, the means for clamping
as herein shown consisting of a clamp-bar B' resting at its upper end against a
laterally projecting arm a of the standard A¹ and bearing at its inner end upon a
flat surface bat the top of the inner portion of the anvil block. The clamp bar B¹
is held against and over the anvil block by means of a set-screw passing through
the clamp bar and entering the standard near the anvil block. is a movable part
or reciprocating die of the clamping or pressing device, said die being arranged
vertically over the end of the anvil block B which projects from the face of the
standard A' and being provided with a "V" shaped notch or recess c in its under
surface forming the working face of the die t. engage with the oblique surfaces bb
of the anvil block. The die C is attached to a vertically movable slide C¹ mounted
in guides a¹ a¹ upon the standard A'.
Said reciprocating die acts in conjunction with a stationary knife or cutter D to
sover the separate jointing strips from the long or continuous strip fed to the machine.
Said stationary knife or cutter is located over the stationary die-block in such position
that the said strip is fed or guided over said die-block as the strip is advanced between
the dies. The cutter is herein shown as held or supported in a removable plate D¹,
which plate is bolted to the frame standard A', and is provided with an opening or
passage d, through which the strip passes to the dies, as will hereinafter more fully
appear.
The slide C¹ which supports the die O, is, in the machine illustrated, moved ver-
tically for actuating the movable die C by the following devices: E is a heavy and
strong bell-crank lever mounted upon a pivot e which is inserted through lugs or
bearings a a² located at the upper end of the standard A' and at the inner face
thereof. The said bell-crank lever E is provided with a short horizontal arm E¹ which.
engages a recess c¹ in the upper part of the slide C¹. Said arm E¹ is herein shown
as provided with a flat spring c arranged to bear upwardly against the upper wall of
the opening c¹ to take up lost motion in the parts. Said bell-crank lever E is pro-
vided with a second arm E2 which extends obliquely downward to a point near the
bed-plate A. E is a foot lever pivoted at its upper end to the machine frame by
means of a pivot pin e arranged near the lower end of the standard A. To the
upper end of said foot lever is attached a rearwardly extending rigid arm E, which
is connected with the lower end of the lover arm E of the bell-crank lover by means
of connecting plates E' E'. When the lower end of the foot lever E³ is thrown
backwardly the lower end of the lever E³ is thrown upwardly and inwardly, and the
slide C and upper die thereby depressed. When the foot lever is thrown forward,
on the contrary, the die is elevated. I have herein shown a bar E7, attached to the
foot lever, sliding in a bracket Es upon the bed-plate A, and provided with a head e³,
as employed to limit the backward motion of the foot lever.
The continuous strip of paper to be fed to, the machine for making the joints, is
mounted upon a reel F sustained upon an arm F¹ attached to the frame. in the
drawing indicates the paper strip. G is a folder, which acts upon said strip after
the latter leaves the reel, to double or crease the same in its middle so that it will
take and maintain a V" shape at the time it is introduced between the clamping
dies.
"
H is a pasting roller the periphery of which is made of "V" shape to fit witbin
the creased or folded lower surface of the strip, and H₁ is a presser roller for holding
the strip in contact with the said pasting roller. The paper strip is carried forward
or fed to the clamping dies after leaving the pasting roller by feeding devices acting
to give an intermittent forward motion to the strip, whereby the end of the latter is
carried rapidly or quickly forward between the clamping-dies and over the margin of

page_text: the box sides placed over the stationary die and remains immovable, while the dies are
being brought together and the jointing piece to be attached to the box is being severed
from the continuous strip.
"
The said feeding device, in its main or essential features, comprises a reciprocating
gripper which engages and carries forward the paper strip in its forward movement,
and becomes released from the strip at the limit of its for ward movement, so as to
move backwardly without producing any corresponding movement in the strip. Tho
particular feature of construction herein. illustrated in the feeding device and means
for guiding the paper strip to the same and from said feeding device to the clamping
dies are as follows: 1 (Figures 2, 4, 5, 6, 7 and 8) is an "L" shaped guide-plate
which serves to guide the paper strip to the clamping-dies and upon which the main
operative parts of the feeding device are sustained. Said plate I is herein shown as
provided with a vertical flange I' at one of its edges which flange is provided with a
longitudinal guide-slot i in which the reciprocating gripper is held and guided. Said
guide-plate is also preferably provided with an arm or bracket 12 by which it is secured
to the machine frame. The main part of the guide-plate I is arranged beneath the
path of the paper-strip, so that the said strip passes longitudinally over said plate
parallel with the guide slot i thereof.
The said gripping device comprises a sliding plate J arranged vertically against the
plate I and held in place by means of a plate J' located at the opposite or
exterior face of the said plate I¹ and connected with the plate J through the slot i.
A filling piece is desirably attached to the plate J within the said slot. J' is the
lower jaw of the gripping device; said jaw being arranged centrally beneath the
path of the paper strip, and provided with a sharp or narrow bearing edge j¹ to
engage the inner surface of the strip at the upper part or crease of the same.
The said jaw J of the gripper is connected with the lower edge of the sliding
plate J by a horizontal arm or plate located adjacent to the plate 1 and with its
upper surface a sufficient distance below the edge of the lower gripper to avoid
coming in contact with the corner margin of the folded or "V" shaped strip passing
over it (Figure 8). In the simple and convenient construction of these parts herein
shown, the plate J, the plate and the gripper jaw J are formed or bent from a
single piece of metal. Ja is the upper or movable gripper jaw, which is arranged
above the lower jaw J' thereof, and is made vertically movable so that it may be
either engaged with or lifted free from the said lower jaw. In the particular embodi-
ment of the invention illustrated, the movable grippor-jaw J³ is formed by or upon
the end of the horizontal lever J, which is mounted upon a pivot pin affixed in
the sliding plate J, said lever J being arranged horizontally and its pivot being
arranged to overhang the path of the paper strip. The working face of the said
gripper-jaw J is herein shown as formed by a separate piece of hard metal serrated
or roughened to more positively engage the strip. J is an arm for actuating the
gripper arm J, said arm J* being attached to and extended upwardly from the arm J*
and having at its upper end a horizontal crank pin j⭑.
In a device embracing the general features of construction above set forth, the
reciprocating part or plate carrying the gripping jaws, and the jaws themselves, may
be separately moved by suitable actuating devices. As a simple and desirable con-
struction of the parts, however, they are herein shown as so constructed that the
reciprocating gripper-carrying plate J and the gripper is driven by actuating devices
provide
engaged with the upper end of the lever arm J alone. For this purpose
frictional engagement between the said plate J and its guide, tending to retard the
movement of the plate, so that when pressure is applied to the upper end of the
arm J in a direction to carry the said upper end of the arm forward, the gripper
arm J will first be depressed, after. which a continued forward pressure upon the
upper end of the arm J will carry the sliding plate and gripper jaws bodily forward.
Similarly, when the pressure is applied to the upper end of the lever Js to move the
same backwardly, the jaws will first be opened and the entire gripping device will
then be moved bodily backward. Any one of a great number of well known devices
may be employed for producing frictional engagement between the plate J and the

page_text: &
guide plate I. The device for this purpose herein shown (Figure 5) comprises
flat spring resting at its middle against the plate J¹, and two screws inserted
through the ends of said spring and through smooth openings in the plate J' and
having screw-threaded engagement with the plate J. The spring holds the
plates J and J¹ in forcible contact with the opposite sides of the guide-plate I', and
by turning the screws j the pressure of the spring may be adjusted as found
necessary or desirable.
Devices herein illustrated for actuating the feeding mechanism are made as follows:
K is a rocking lever which is pivotally supported upon a shaft k mounted in the flange
or web A of the machine frame at a point near the rear end of the machine.
Adjacent to its pivotal point, the lever K is provided with a rigid arm K' with which
arm is engaged a bar K2, the opposite or lower end of which is pivoted to the foot
lever E. The rocking lever K is connected with the lever arm J of the feeding
device by means of a connecting rod K³ engaged with a pivot upon the lever K,
and with the pivot pin 4 of the said arm J.
The upper end of the bar K2 is not pivotally connected with the arm K' of the
lever K, but said arm K¹ is provided with a stud which engages a notch k in the
upper end of the said arm, and said lever is held in position for the engagement of.
said notch with the said stud by means of a supporting surface or abutment upon the
machine frame, herein shown as formed by an anti-friction roller K. The lever. K is
held at the rearward limit of its movement by a suitably applied spring, so that tho
forward movement only of the gripping device is given by the action of the bar K2
and foot lever, the rearward or return movement of the gripping device being afforded
by said spring.
In the particular construction herein shown in these parts, the shaft k of the lever K
is rigidly attached to the arm and extends through and has bearing in the frame
plate or web A³. The said shaft, furthermore, extends outside of the web A² and is
provided at its outer end with a collar to which is attached one end of a spirally
coiled spring K³, the opposite end of which is attached to the frame. Said spring
tends to hold the rocking lever K normally at the rearward limit of its movement,
and acts to promptly return the gripping devices to the starting point of the same
after the bar K2 has been drawn downwardly or retracted.
The stud of the arm K' is so located with reference to the bar K2 that said stud
will swing forward out of the notch 3 of said arm after the arm has been lifted a
short distance and when the lever K has been swung forward a sufficient distance to
give the movement in the gripping devices necessary for properly feeding the paper
strip. The said bar K2 may be held from being carried forward away from the
roller K by means of a roller K, or otherwise. After the notch k³ of the bar K' is
released from the stud the upward movement of the bar is continued as the foot
lever is thrust backward, without producing any movement in the gripping devices,
until the clamping dies have been brought together and the necessary pressure put
upon the parts to be joined and the jointing strip.
For applying jointing strips in the making of boxes of different sizes, it is
obviously desirable that the distance to which the strip is fed forward past the cutting
or severing devices at each advance movement of the feeding mechanism, should be
capable of variation, in order that the length of the strip used upon the box may
correspond with the depth of the same. In connection with the stationary die or anvil
block which is movable bodily to afford a greater or less distance between the cutting
off mechanism and the end of the block, as hereinbefore described, I have provided a
connecting mechanism between such movable anvil block and the parts by which the
feeding devices are actuated, whereby the movement of the block a certain distance,
will produce a corresponding change in the throw of the gripping jaws, whereby
the length of the strip fed forward at each reciprocation of the gripping jaws will
correspond approximately with the length of the exposed part of the anvil block and
the joint to be made.
Devices herein shown for the purpose above described are constructed as follows:
The pivot pin k' which connects the rocking-lever K with the connecting rod K³,

page_text: instead of being immovably secured in the lever K is adapted for longitudinal move-
ment upon said lever. For this purpose the said pin is herein shown as mounted
upon a sliding block L engaged with a guide groove in the said lever. L' is a
bell-crank lever which is mounted upon a pivot located beneath the inner end of the
anvil block or bar B and provided with an upwardly extending arm having engagement
with the block, and with a horizontal arm, the free end of which is connected with
the said sliding block L by means of a connecting rod L². The connection between
the bell-crank lever L' and the anvil block B is herein shown as formed by means of
a plate attached to the side of the said anvil block and provided with a vertical
groove which engages a pivot pin in the upper end of the vertical arm of said
bell-crank lever. When the said anvil block, connected with the pivot pin of the
lever K in the manner described, is thrust inwardly, said pivot pin will be carried or
moved upwardly away from the shaft of the said rocking lever K, thereby giving a
greater throw to the said pivot-pin and increasing the throw of the gripping devices.
When, on the contrary, the anvil block is moved inwardly, the pivot k¹ is moved
inwardly upon the rocking lever K, thereby decreasing the throw of said pin k¹ and
giving a less movement in the gripping devices, and decreasing the distance through
which the paper strip is fed forward at each action of the feeding mechanism.
The particular construction herein shown in the guide-plate for guiding the
paper strip on the pasting roller to the gripping devices and from said gripping
devices to the clamping dies is as follows: At the rear end of the guide plate I¹ is
located a rigid plate I arranged at right angles with said guide plate and extending
over the path of the paper strip. Said plate I is provided in its lower edge
with a
"V" shaped notch to engage the upper surface of the strip. Upon
the end of the plate I opposite the said guide plate I³, is located a "V" shaped guide
bar I which also extends over the strip and engages the upper surface thereof.
Along the upper surface of the plate I, at the central line of the paper strip, is located
a longitudinal guide strip I consisting of a narrow strand or filament of metal, the
upper margin of which is arranged in approximately the same horizontal plane as the
upper end of the lower gripping jaw J³, and which is constructed to engage the under
surface of the paper strip within the seam or crease thereof. The purpose of this.
said guide strip is to hold the paper strip accurately in position with relation to the
gripping devices, so that the crease in the paper strip will come exactly over the lower
gripping jaw and thus prevent a distortion of the strip when the same is gripped
between the jaws. The said strip I' is herein shown as supported by being attached
to a plate which is secured to the plate I at the end of the latter at which the paper
strip enters the guiding devices. At its opposite or forward end the guide strip I'
is unsupported, the plate I being cut away beneath the strip at this point so as to
form an opening or recess I (Figures 4 and 7) within which the upper edge or corner
of the working face of the anvil may enter, when said anvil is thrust inwardly for
operating upon shallow boxes or covers. The said guide strip I may, however, be
sustained or held from lateral movement by engagement with the lower gripping
jaw J' at one side of which said bar passes. A preferred construction in these parts is
illustrated in Figure 8 in which the guide strip is shown as beveled at one side only
to give it a sharp or narrow edge located at that face of the strip which is in contact
with the gripping jaw, while the said jaw has a similar shape, being made flat at its
side in contact with the guide strip and beveled at its opposite or outer side. By this
construction the upper edges of both the strip and gripping jaw may be made to
engage the crease of the paper strip, while at the same time the said gripping jaw
may be reciprocated without interfering with the guide strip. If found necessary or
desirable a small lug or projection may be placed upon the arm in position to
engage the inner face of the guide strip I, thereby forming with the jaw J' a notch
in which the said guide strip is held and guided. The said notch will, however, be
made slightly deeper than the thickness of the guide strip, so that the upper gripping
jaw will act against the lower jaw J2 and will not press against the upper edge of the
guide strip.
I' I' are two guide rods, which are located above the guide-plate I, one at each side

page_text: of the guide-strip I at such distance apart as to engage the upper surface of the paper
strip near the lateral margins thereof. Said guide rods aid in keeping the strip
accurately in position with relation to the gripping jaws of the feeding mechanism,
and are also of use to prevent the sides of the folded or creased paper strip from bending
or curling up, on account of the moisture of the paste or glue applied thereto. The
said guide bars 1' I' may be attached to or supported from the plate I in any desired
manner. As herein illustrated they are inserted and secured to their ends in the guide
plate I and guide bar I^.
At its end nearest the clamping dies the plate I is herein shown as provided with
a "V" shaped extension I adapted to enter the opening d of the plate D¹ by which.
the stationary cutter D is directly supported. Said plate I serves to guide the paper
strip until the latter reaches the said cutter. The projection 18 is herein shown as
provided at its top with a vertical flange Is the upper edge of which rests against the
top of the said opening d. The sides of the said projection 18, together with the
flange I serve to hold the ends of the guide devices accurately in position with
reference to the knife and the clamping dies by their engagement with the walls of
said opening d.
I have found that in the use of rollers H H³, such as are herein shown, for applying
paste to the paper strip; that when the said strip is carried or moved rapidly forward
by the action of the feeding mechanism described, the impetus acquired by the paste
rollers as they are turned by the paper is liable to cause the said rollers to continue
to turn in a manner to thrust the paper forward, after the gripping jaws havo
completed their forward movement. To avoid this result I so construct the upper
roller H that it may be lifted to free it from the lower roller H, and I provide means
whereby the upper roller will be automatically lifted free from the lower roller at the
moment forward movement of the gripping jaws is terminated. When the parts are thus
constructed the paper strip is released from the paste rollers before the latter have an
opportunity to act upon the strip in a manner to carry it forward. For the general.
purposes above set forth, the upper feed roller may be lifted or moved by any upwardly
moving part of the machine acting against the feed roller support at the proper
time.
In one practical embodiment of this part of the invention herein illustrated, these
parts are made as follows: The upper roller H¹ is mounted upon a pivot pin h¹
having bearings at its opposite ends in two parallel arms H H which are rigidly
connected with each other and are mounted upon a rigid pivot pin h³ affixed in the
frame plate A². Upon the end of one of the armis H is formed or attached an arın
or striker H3 located in position to engage the stud of the rocking lever K when
the said stud has nearly reached the upward limit of its movement. When the said
lever K is actuated by the notched bar K³, therefore, the supporting arms H2 H2 and
the roller H will be lifted at the moment the feeding device reaches the forward limit
of its movement and said roller H¹ will be supported free from the paper strip, until
the foot lever is swung rearwardly and the bar K² retracted preparatory to another.
and succeeding operation of the machine. The lower paste roller H is constructed to
enter a tank or receptacle A containing paste or other adhesive substance so as to
become coated upon its margin in a manner heretofore common and well understood.
H³ is a scraper arranged to fit against the "V" shaped, periphery of the said feed
roller to remove the surplus adhesive substance therefrom.
The cutter or shear blade D, employed to sever that part of the jointing strip applied
to the box walls froni the main or continuous part of the strip, in the manner herein-
before stated, acts, in the particular construction illustrated, in connection with the
cutting edge formed at the rear surface of the movable clamping die C, as the movable
die descends toward the work. Any separate knife or cutter on the movable die is
rendered unnecessary in the particular construction shown, by making the rear face
and working surface of the movable die of hardened steel.
The stationary knife or cutter M is herein shown as made preferably of thin or
sheet metal and of inverted "V" shape said cutter being secured to the plate D' by
screws, as shown. A plate M¹, secured to the plate DI above said cutter, aids in

page_text: holding the same in place. Said plate M' is provided with an opening m¹ (Figure 10)
through which the strip passes over the knife. The forward or advance edge of the
cutter forms the cutting edge thereof, and the said cutter is held up to its work by
screws placed behind it or other wise.
"
The movable die C may be constructed in any suitable or preferred manner to
afford a suitable cutting edge at its rear surface. In the particular construction
herein illustrated the working surface of the die is formed in a cylindrical block (2
of hardened steel the lower surface of which block is provided with a "V" shaped
notch corresponding in form with opposing surface of the die block D). The rear or
inner end surface of the said hardened blocks rests in contact with the edge of the
cutter M so that the square edges of the notch act in connection with the said cutter
to sever the paper strip. I have herein shown the block C as held within the head
of the die by splitting the latter vertically and inserting one or more clamp screws
for holding the split parts together. A screw e inserted in the head and over-
lapping the die block C serves to hold the guide block from being thrust endwise out
of the head, and to adjust said block with reference to the stationary cutter.
In Figure 13 is shown the cut and scored corner of a box blank before the
jointing strip is applied to the same, and in Figure 14 is shown the finished corner
after the jointing strip has been applied. In the operation of the machine the
operator sits or stands in front of the same and places the corners of the box blank
split and scored as shown in Figure 13, upon the upper surface of the anvil B below
the movable die, the sides of the box being bent or held approximately at right
angles with the bottom when the blank is placed upon the anvil block. When the
corner of the blank is thus held upon the block the foot lever E³ is actuated, with
the result of quickly thrusting forward the end of the strip over the edges of the
blank and then depressing the upper die to sever the strip and forcing it into
contact with the surface of the blank. The folder G herein shown, comprises a
curved plate G which is bent into tubular shape, with the side walls arranged at
some distance apart at their rear ends but brought together or parallel with each other at
their forward ends, so as to gradually bring together the margins of thestrip, thereby
bending the paper strip into " U" shape, and to then fold or crease the strip as it
emerges from the folder.
The machine herein shown illustrates one practical embodiment of the main features
of my invention which latter may obviously be carried out by a mechanism differing
materially in its details from the particular one herein shown. One of the main
features of the invention is embodied in a construction embracing a clamping device
and guides for directing the paper strip to the clamps, and, as far as this feature of
the invention is concerned, the paper strip may be fed to the clamping dies flat or
uncreased, and automatically acting feeding devices may or may not be employed. A
construction embracing such automatically acting feeding mechanism is, however,
herein claimed as a separate improvement.
Another important feature of construction herein illustrated embraces the connection
between the movable or adjustable anvil block and the actuating devices by which the
feed devices are operated whereby the length of paper fed forward at each motion of
the machine may be varied to correspond with the depth of the box to cover, and, as
far as this feature of the invention is concerned the gripping devices may be made
otherwise than in the particular manner illustrated, and the connection between the
movable die block and the said actuating devices may be made otherwise than as
shown. The particular machine illustrated, however, contains many novel details of
construction which in themselves are made the subjects of specific claims herein.
