Improvements in Paper Box Making Machinery.
"
I, MARTIN EUGENE BRIGHAM, Manufacturer, of 248 North Third Street, Phila-
delphia, in the County of Philadelphia, State of Pennsylvania, United States of
America, do hereby declare the nature of my invention for IMPROVEMENTS IN PAPER
Box MAKING MACHINERY," and in what manner the same is to be performed to bo
particularly described and ascertained in and by the following statement :-
My invention has reference to paper box making machinery and consists of certain
improvements which are fully set forth in the following specification and shown in the
accompanying drawings.
The object of my invention is to provide means for cutting and perforating
cardboard or equivalent material into the proper shape and forming the ends of
the same so that they may be united to form a cylinder. This cylinder, after
having its edges united, has a stamped cardboard head glued or cemented on ono
end, and after being filled with the material which it is to contain the other head
is placed on the open end and a label securely pasted about the body to secure
this head or lid upon the box, which has the effect at the same time of making
the box as an entirety practically air-tight.
My machine is designed for making the cylindrical or body portion of the box.
In the cheaper articles of commerce it is impracticable to use anything but a
paper receptacle, and heretofore, as far as I am aware, there has been no machine
for forming the cylinder of a paper box with sufficient rapidity and economy.
By the machinery herein set forth, in a very limited time a large number
of pieces of cardboard may be cut and prepared for the formation of the paper
cylinders.
In carrying out my invention a roll of cardboard is fed between suitable cutters
by which it is cut into appropriate lengths and widths having the ends of each
piece notched and perforated to form a means of attachment between the two
ends of the cardboard constituting the cylinder. The cut cards so notched and
perforated are automatically received by a curling or forming device whereby
they are curled or rolled into the cylinder shape, approximating that which they
finally assume. The feeding, cutting and curling devices are geared together
or otherwise connected, and are so timed that the mechanism is automatic in its
action.

of Fig. 2 of a card cutting and
forming machine embodying the principles of my invention.

connecting the ends together.

formed into the cylinder, and,

label attached.
A is the frame of the machine. B is a roll of cardboard or other material carried
upon a suitable support B', and fed from the roll between suitable feeding rollers C, C.
These rollers C, Care geared together at cc and their pressure upon the cardboard
is regulated by the adjusting screw D. E is a guiding roller over which the
cardboard passes as it is fed from the roll to the feeding rollers CC. F is a
roller provided upon its surface with recesses or dies in which are attached suitable

page_text: intended to cut the cardboard transversely of the desired width, short notching
cutters by which the cardboard is notched upon one of its ends when it, is
divided by the transverse cutter f, and a perforating cutter separated a short
distance from the transverse catter for the purpose of forming a slit or porfora-
tion in the end of the cardboard opposite to that which is provided with notches
by means of the cutters ff. These plates G, provided with the cutters f₁ff,
are secured in the recesses upon the roller F by means of screws g or otherwise,
and the adjacent cutters are arranged out of line with each other upon the
surface of the roller so as to act successively upon the cardboard as illustrated in
the drawings.
His a backing roller to form a backing or support for the cardboard while it
is being cut by the cutters G. The rollers F and H are geared together by
suitable gearing ƒ³ and h, and the roller F is journalled in adjustable bearings so
that it may be adjusted to or from the roller H by means of an adjusting screw I.
The teeth of the gear are made of sufficient depth to allow the gear to be
raised in its bearings a sufficient distance to lift the cutters G out of operation
without destroying the gearing connection between the gears and h.
JJ are rollers which are respectively provided with circular cutters K, K, which
may be secured to the rollers J J by means of screws or in any other convenient
manner. By these cutters the cardboard, after it has been notched and perforated
and cut transversely, is split or cut longitudinally so as to be separated into the desired
sizes for the formation of the paper tubes. The number of these cutters may be varied
as desired. It is apparent that the number of the circular splitting cutters K should
correspond to the number of the transverse and notching and perforating cutters G.
The rollers J J are geared together by suitable gearing j
The power is transmitted from the roller F to the longitudinal cutting rollers J J
by means of chain and sprocket wheels I. Motion is imparted to the feeding
rollers CC similarly by means of a chain and sprocket wheel L' from the roller F.
Located in the rear of the cutting rollers J J are curling rollers O P, the former of
which is mado solid, while the latter is provided with an elastic or rubber covering p
and these rollers are pressed together by an adjusting screw Q, so that the cardboard
in passing between them is bent similar to the curvature of the roller O and is thereby
set in a curved shape and is guided by the curved plate R in the rear of said rollers.
The blank as it leaves the curling rollers is shown at S. These rollers are geared
together at oo and receive motion by a chain and sprocket wheel L from the
cutting rollers J J. Their surface speed is somewhat in excess of that of the
cutting rollers F H and J J so that the card is passing through them is separated
from the next advancing card to a slight extent to provent then conflicting. T is
a guide over which the cards pass from the cutting rollers J J to the curling
rollers P and O. By raising the cutting and notching roller F as described so as to
bring the cutters G out of operation I may employ the cutters K K alone for cutting
the paper into longitudinal strips. Figure 7 shows a section of the box complete,
i being the body the bottom the lid and the label of the same.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim :-
First. In a machine for forming paper box bodies a cutting cylinder having a
series of short transverse slitting cutters arranged thereon, each transverse cutter
being out of line with the adjacent transverse cutters whereby the adjacent transverso
cutters shall act at different moments, in combination with a solid roller upon which
the cutters cut, and cutting devices for cutting the paper longitudinally...
Second. In a machine for forming paper box bodies, a cutting cylinder having a
series of short transverse cutters arranged thereon and out of line with each other
whereby such transverse cutters shall act succossively, in combination with a solid
roller upon which said cutters cut, and cutters for cutting the paper longitudinally.
Third. The combination of a cutting cylinder provided with a series of removable

page_text: cutting plates G for cutting the cardboard transversely, the cutters J J for slitting
the cardboard transversely, and gearing between said cutting cylinders whereby they
shall rotate at substantially the same speed.
4th. The cutter for a paper box machine consisting of a straight cutter having two
oblique cutters f1f1 extending therefrom approaching each other at their free ends,
and a cutter f parallel to the cutter f and arranged at a distance from the cutter f
equal to the distance of the free ends of tho cutter f' from the cutter f and having
a length equal to the distance between the free ends of the cutters f¹ substantially
as shown, a series of said cutters being arranged upon a cylinder out of line with
each other so as to act successively upon the cardboard, or material to be cut.
5th. In a machine for forming box bodies the combination of the transverse cutting
rollers, the longitudinal cutting rollers, the curling rollers, and gearing connecting
the curling rollers, and longitudinal rollers, whereby the curling rollers move at a
greater speed than the cutting rollers.
6th. In a machine for forming paper box bodies the combination of a support for a
roll of cardboard, cutting rollers to cut the cardboard transversely into short lengths
of the proper shape, circular cutting rollers to cut the cardboard longitudinally, and a
curling roller substantially as described to cut or curl the cardboard into a circular
shape.
