I, ALEXANDER HENRY REED of Suffolk House, Laurence Pountney Hill, Cannon
Street, in the County of Middlesex, Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to a machine for applying adhesive fastening strips to boxes,
and it consists in a certain mechanism for intermittently feeding the strip directly
between a punch and die, mechanism for cutting the same to any particular length to
correspond with the depth of the box operated upon, means for applying the several
strips to the box, and devices for turning inward and downward one end of the strip
to secure the same to the inner surface of the sides of the box, all of which is fully
pointed out in the following specification and claim, and illustrated in the accompanying
drawing, in which
Fig. 1 represents a vertical section in the plane x x fig. 2 of a machine embodying
the invention.
Fig. 2 is a vertical front elevation of the same.
Fig. 3 is a sectional side elevation.
Fig. 4 is a perspective view of a box with the fastening strips applied.
Figs. 5 and 6 are perspective views of detail parts, said views being drawn to a

position from that shown in fig. 10.
Similar letters indicate corresponding parts.
In these drawings the letter A designates a frame suitably constructed to sustain

page_text: the operating parts of the machine, and B is a table forming part of the frame,
which table is properly made to receive and support a die C. The cheeks c
fig. 2, of said die form an angle of 90° with each other to adapt the die for the
reception of the corner of the box as W, fig. 4, to which the fastening strips are
to be applied. The punch D is located above the die and is provided with cheeks dd,
fig. 2, extending parallel with those of the die C. Said punch is moveable in the
direction of its length, its shank d¹ being guided in vertical ways formed in an
overhanging portion A¹ of the frame A, and it is moved toward and from the die C
by any suitable mechanism, such for instance as shown in the drawing by a
weighted bell-crank lever E E', figs. 1, 2 and 3, which is pivoted to the frame
and is vibrated by the foot of the operator.
It will be observed that the punch projects outwards from its shank, which
permits the box W to be placed thereon in the proper position without interference,
as best seen in figs. 7 and 8.
The fastening strip S is fed directly between the punch and die by any suitable
feeding device. In the example illustrated it is drawn from a roll S¹ best located
directly beneath the table B by a feed roll F which rotates in contact with a
combined feed and paste roll G, located within a paste fount G¹. The shafts of
both rolls have suitable bearings in a standard g, figs. 1, 2, 7 and 8, extending
vertically from the paste fount. If the fastening strip has been previously supplied
with a dry coating of mucilage, water is supplied to moisten the same by the
paste roll G. The feed roll F is so located that the strip S passing from the
same is on a level with the upper surface of the die C to which it is fed. The
inner end of the die is prolonged (figs. 1, 7 and 8) to form a flat support ƒ for
the fastening strip S, and suitable parallel guides as f¹f located on the upper
surface of the die C are provided to keep the strip central with the die as it moves
toward and over the same. A presser plate f" holds the fastening strip down upon
the' support f.
A creasing device such as a roll H having moderately keen edges, rotates above
the feed roll F and engages with the fastening strip forming therein a continuous
central depression or crease. This crease facilitates the bending of the strip and also
acts to guide the paper into a correct position as the corner of the box comes into
contact therewith. The cutter I which can be in the form of a keen edged knife or
chisel is located in proximity to the rear of the punch and severs the fastening strip
into definite and equal lengths.
It will be observed that the shafts of the creasing roll and the feed and paste
rolls are connected by suitable gears as shown in fig. 2.
To protect and securely fasten the upper free edges of the box, the fastening strip
(see fig. 4) is usually carried over said edges and secured in the interior of the box.
In view of this, the fastening strip must be cut into pieces somewhat longer than the
depth of the box, and to this purpose the cutter I is set at the proper distance from
the rear end of the punch.
"
A motion toward and from the fastening strip can be imparted to the cutter I by
any suitable mechanism, but in the example shown in the drawing the cutter is
secured directly to the shank d¹ of the punch, such being the most convenient way of
obtaining the requisite motion. The cutter passes directly in front of a sharp edge f*,
fig. 8, of the support f, whereby the strip is severed. The usual devices for effecting
the adjustment of the cutter with regard to the strip are provided. The cutter is best
set to act slightly in advance of the punch D so as to sever the fastening strip before
it is engaged by the latter, whereby the severed length is prevented froin being
crumpled.
To intermittently feed the fastening strip forward through the desired distance any
suitable feeding device can be employed. In the example shewn in the drawing (see
fig. 3 especially) a ratchet wheel J is rigidly secured to the shaft of the feed roll E
which ratchet wheel is in a position to be engaged by a toothed har J' which is
-adjustably secured to the shank of the punch D and consequently moves with the
83me.
L

page_text: The bar J¹ may be hinged or provided with a thin portion as shown, so that it ca
yield on its descent to clear the teeth of the ratchet wheel J, which is held stationa
during this stroke of the bar J by a pawlj pivoted to the standard g. In the upward
stroke of the toothed bar J¹ the teeth thereof engage with the ratchet wheel to rotate
the same, thereby actuating the feed roll F to move the fastening strip. On inspection
of fig. 7 it will be noticed that the punch D intersects the path of the fastening strip,
and consequently the feed must be so timed that the strip will not come into contact
with the same.
This is accomplished by so setting the toothed bar J with respect to
the ratchet wheel J¹ that it does not engage the same until the proper time (see fig. 8).
To adapt the machine for boxes of any particular depth, plates d' are provided which
can be secured by screws to the punch D so as to bring the top or free edge of the
box always in the same vertical plane which is necessary to preserve equal lengths of
the overlapped portions of the severed strips and also for the correct operation of the
device which performs this overlapping. With varying depths of boxes, the feed
must be varied correspondingly, which can be accomplished by adjusting the position
of the toothed bar J₁ with respect to the ratchet wheel J. By setting the same lower,
less teeth are caused to engage with the ratchet wheel and a smaller feed is the result,
The adjustment of the feed can also be effected by using ratchet bars J¹
each having thereon a particular number of teeth to correspond to a particular length
of feed desired.
and vice versa.
To carry over and to lay the fastening strip in the corner of the box, devices as
follows are employed. At the inner ends of the cheeks c c or in a position a trifle
beyond the edge of the box, when the latter is in the die, is formed a ledge or
projection L which extends outwardly from said cheeks and engages with the fastening
strip S just beyond the edge of the box as the descends in the die, whereby said strip
is turned about the edge of the box to occupy a position approximating that shown
in fig. 7. This ledge or projection L, is hereafter termed the stripturner L. When
the end of the fastening strip is thus turned it is in a position in which it can be
engaged by a folder M, figs. 1, 2, 5, 7 and 8, on the subsequent withdrawal of the
punch D. The folder completes the turning or bending of the strips and lays the
bent over portion upon the interior of the sides of the box. The folder is provided
with two cheeks forming an angle of 90° with each other to correspond to the angles
of the box. It is secured to a shaft m having bearings in a slot extending horizontally
through the die and table. To the ends of said shaft m are rigidly attached links n n
which connect said shaft with the vertical arms of crank lovers N N that are secured
to the opposite ends of a rock shaft n' having bearings in the table. The horizontal
arm of one crank lever N has a pin and slot connection with a rod o, figs. 2 and 3
especially, which extends upwardly and is vertically guided in a box o on the frame
of the machine. To the upper end of the rod is hinged an arm P (see also fig. 6)
which is normally held in line with the rod by a spring p bearing upon the arm.
In
said arm P is a slot q which can receive a pin R secured to the shank d₁ of the
punch D. This pin engaging the arm P at the upper end of the slot carries the same
upward with it until a cam surface » (see fig. 6 especially) on said arm engages with
stationary cams R' R', figs. 2 and 3, on the frame, whence the hinged arm is swung
outward and clear from the pin. Á retractor such as a spring t encompassing the
rod O and confined between a shoulder on the same and the box o on the frame A
immediately withdraws the rod O on its release from the pin. A stop u on the rod O
engages with the box o and checks the falling motion of the rod.
During the rising motion of the rod, the folder M is carried forward toward the
box W and at the same time gradually turned downward or oscillated with the shaft m
whereby it is caused to engage the free end of the fastening strip S and to lay the
same within the box as described (fig. 8). During the fall of the rod O the folder
is returned to its normal position fig. 7.
The oscillating motion of the shaft m and consequently that of the folder M is the
result of the change in inclination of the links n n during the vibration of the crank
levers N, fig. 7 and 8. This oscillatory movement of the folder combined with

page_text: its translatory movement causes the strip to be neatly and securely laid within
the box.
The object of releasing the rod O which actuates the folder, before the return or
downward stroke of the punch D, is to allow the folder to reach its normal position
(fig. 7) before the descent of the punch, as it will be seen from fig. 8 that the
folder operates during the upward stroke of the punch, i.e. when the same is out of
the path of said folder.
It is evident that other mechanism can be employed to successfully actuate the
folder and consequently any other suitable mechanism may be used for that purpose.
To prevent the fastening strip from peeling off when the box is handled while in
use, the outer face of the strip is caused to lie flush or a little below the faces of the
box (see fig. 4), so that they cannot catch into foreign bodies This is done by
making the cheeks cc of the die C of approximately one half the width of the
strip and then causing the punch to descend with sufficient force to compress the
material of the box and thus force the strip inward and flush with the sides of
the box. The same can be done in the case of the overlapping portion of the strip
by causing the folder to act with sufficient force.
Instead of feeding the fastening strip lengthwise between the die and the punch,
it can be fed transversely between the same. This is preferable when the box is
very deep, as the strip when fed lengthwise between the punch and die is liable to
turn out of its course.
A machine embodying in its construction a device for feeding and fastening the
strips transversely is illustrated in figs. 9, 10, and 11. In this machine the die C is
made moveable and the punch D is rigidly secured to the table B and forms an anvil
or support for the box as before, said box being applied thereto as shewn in figs. 10
and 11. The feeding device for propelling the strip directly between the punch
and die is situated on one side of the punch and feeds a strip having a width corre-
sponding to the required length or depth of the strip as applied to the box.
In the example shewn in the drawing, figs. 9, 10 and 11, the feeding device
consists of two feed rolls F and G, one of which is located in a paste or water
fount G¹. The feed rolls are actuated from the reciprocating die by a ratchet
wheel J and toothed bar J but may be driven by any other suitable means.
The strip S is fed over a support which can be conveniently formed on the
paste fount, and the inner side of which is parallel to and almost in line with a flat
cutter I attached to the corresponding side of the die C. At the beginning of the
downward stroke of the die C, the feed rolls F and G are actuated and feed the
strip S between the punch and die that is over the corner of the interposed box W
(see fig. 10). After the completion of the feed, the descending cutter I severs the
strip. To additionally support the strip while being severed, and to hold it firmly
upon the interposed box, use is made of a clamp U which is fitted loosely in a central
longitudinal recess in the die and is subjected to the action of springs u which tend
to force it outward from the die to the position shown in figs. 9 and 10 in which
position its motion is arrested by stops u engaging the die. In the outer end of
the clamp is a longitudinal groove corresponding to the corner of a box. As the die
descends towards the box, the clamp U engages with the strip and holds it firmly
while the strip is being severed by the cutter I; on the further movement of the die
the clamp yields, until its outer end lies flush with the cheeks c c of the die (fig. 11).
In this position its inner end engages with the end of the recess and the clamp
consequently forms an unyielding and operative portion of the die when said die is
in engagement with the strip (fig. 11).
Instead of having one long clamp several short clamps could be arranged in the
length of the die to produce the same effect.

tion, and in what manner the same is to be performed, I declare that what I
