PROVISIONAL SPECIFICATION.
A New or Improved Machine for Covering Cardboard Boxes, and Boxes
Made of other Material, with Enamel and other Papers.
WALTER ETHARD GOSS and JOHN Goss, of High Street Kettering, Printers,
Stationers, Book-binders and Boxmakers, and ALFRED DAWES of Stamford Road,
Kettering, Millwright, do hereby declare the nature of this invention to be as
follows:-
For banding paper on ready made cardboard boxes, which we perform by having
one large wheel, and one small wheel; one third revolution of the large wheel,
which is worked by a treadle, causes one revolution of the smaller wheel, to which
the dummy for placing the cardboard-box is fixed, on shaft or spindle of same;
therefore-at oue revolution of the small wheel, the knife is so connected to the
treadle, that it cuts the paper required at a given point, making the banding and
cutting, performed at one operation and by one operator.
Our knife is counterbalanced by a weight, or spring, so as to take the knife back
'into its original position.
We also have a cushion made of india-rubber, or spring, to prevent the sticking
of the knife by glue or paste used for sizing the paper.
In our machine we have an arrangement for gluing or pasting the paper necessary
for cardboard box covering.
The arrangement we wish to protect is the rise and fall of the gluing or pasting
roller. The rise and fall of the roller is caused by gluts, or side bearings, which
are regulated by ordinary thumb-screws or wheels. By this side motion we regulate
quantity of glue, or paste required for the various kinds of work.

A New or Improved Machine for Covering Cardboard Boxes, and Boxes
Made of other Material, with Enamel and other Papers.
We, WALTER ETHARD Goss and JOHN Goss, of High Street, Kettering,
Printers, Stationers, Bookbinders and Boxmakers, and ALFRED DAWES, of
Stanford Road, Kettering, Millwright, 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 paper box covering machines of the kind wherein the
" former" and wherein
boxes to be covered are carried on a rotatable dummy or
the covering paper which is drawn from a roller is automatically cut off to the
desired length.

page_text: The machine constructed according to our invention is operated by means of a
treadle, and in order that the downward movement of the treadle shall produce a
complete rotation of the dummy or former the latter is driven by gearing, a pinion
upon the shaft of the said dummy or former being in engagement with a wheel
rotated by the treadle through the medium of a crank and connecting rod.
It is advantageous to make the said pinion and wheel in the proportion of one to
three so that one third of a revolution of the said wheel will produce the complete
rotation of the pinion.
The paper severing mechanism comprises a fixed blade and a movable blade, the
latter being counterbalanced or arranged in conjunction with a spring so that its
normal tendency is to remain open. The movable blade is operated from the
treadle by suitable levers and links, the said links serving to allow the downward
movement of the treadle to rotate the "former
mechanism until such time as the
without operating the severing
revolution.
has practically completed its
"former"
"
The usual pasting or glueing roller of the machine is supported in adjustable
bearings to permit of regulating the position of the said roller relatively with the
level of the glue or paste and thereby controlling the quantity of the latter applied
to the paper strips.
-
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a longitudinal section of our machine :
Figure 2 is a sectional plan of the same; and,
Figure 3 is a front elevation with the duminy removed.
a, a are the standards or side-supports of the machine; b is the drum upon which
the roll of paper is wound, the said drum being mounted on the spindle c carried by
the side-supports a, a as shewn; d is the glue or paste receptacle, and e is the roller
which rotates in the same, the said roller being mounted on a spindle f supported in
bearings g, g the height of which can be adjusted by means of the screws h, h so
that the roller e can be caused to be more or less immersed in the glue or paste.
i is a lamp (or a gas jet may be used) placed under the receptacle d for warming
the same, the said receptacle being provided with downwardly projecting ends j, j
to protect the paper from the heat of the flame.
k is the dummy or "former" which as usual is made to correspond with the
shape and sizes of the boxes to be produced, and is the spindle on which the said 3
dummy is fixed by means of a thumb-nut m and washers n, n, the said spindle
being mounted in a bearing in one of the standards a, as shewn clearly in
Figure 2.
o is the pinion or smaller toothed gear-wheel keyed to the said spindle l, and
p is the larger toothed wheel engaging with the said pinion and mounted on one end 4
of a shaft at the other end of which is fixed a crank r. It will be obvious that.by
arranging to operate the former by means of gearing as described, the crank having
to make less than half a revolution can be so adjusted that it will not have to pass
over a dead centre.
is the treadle by means of which the machine is operated, the said treadle 4
being pivoted at t to the standards a, and u is a connecting rod between the treadle
and the crank r.
is the lower fixed knife of the severing mechanism, and wis the upper movable
knife, the said upper knife being pivoted at w at a point below the upper edge of
the fixed knife v. The boss to of the movable knife w has formed in it a notch w 5
in which a pin to engages so as to limit the up-and-down movement of the knife w.
to is a spring connected at one end to a hook 10 attached to the movable knife and
at the other end to a screw u in one of the standards a, the said spring being of
sufficient strength to normally keep the knife w.in the raised position shewn in
Figure 3.
x is a shaft mounted in suitable bearings in the framing a and carrying at one end
a lever y connected at its outer end to a link y' which is also connected by a pin y²

page_text: to the knife r. At the other end of the said shaft x is a short lever z, say one-
third of the length of the lever y, connected by links ', to the treadle, a
universal joint being placed between the link and the lever .
These two-
links 2, when the treadle is raised are at an angle to one another, as shewn
clearly in the drawing, so that when the treadle is depressed the said links.
will move until their axes are situated in a straight line before the knife is
operated.
A weight is placed on the lower end of the treadle for returning it after it.
has been depressed, and adjustable stops s¹, are arranged to limit the movement.
of the treadle.
A weight is attached to one end of a cord 2 passing over a pulley 63 on the
spindle con which the paper roll 6 is mounted, the other end of the cord being
attached to a pin 6 on one of the standards the object of the said weight and cord
being to brake the drum on which the paper is wound and so apply tension to the
paper when being unrolled. el, el are guide-rollers over which the paper passes,.
and is a scraper for removing superfluous paste or glue taken up by the paper
from the roller e.
The operation of the machine is as follows:-The cardboard box to be covered
is pushed on to the dummy k which is in any suitable position such as that shewn in
Figure 1. The paper is then pulled from the roll, passing over the pasting and guide-
rollers and through the severing device and its end attached to the box on the dummy,
as shewn clearly in Figure 1. "The treadle is then depressed to rotate the dummy
whereby the paper is wound around the box.
During the greater part of this revolution the knife to remains inoperative, the
links, being moved so as to bring their axes into a straight line.
As soon,
however, as the links are in a straight line at which time the rotation of the
"former" is nearly completed, the upper movable knife is caused to suddenly drop
and sever the paper, the suddenness of the operation of the knife being due to the
arrangement of links and levers controlling it. By correctly arranging the point
at which the cutting off takes place relatively with the rotation of the "former" it
will be obvious that just sufficient paper can be allowed to exactly cover the box so
that all waste by overlapping is avoided and a sharp clean cut is obtained on account
of the celerity with which the knife operates. When one complete revolution of
the dummy has been made, pressure is removed from the treadles so that it is
returned to its upper position by the weight and the dummy is rotated backwards
into its previous position. The covered box is then removed and an uncovered box
substituted for it and the above described operation is repeated.
To cover the upper surface of a box lid, the lid is placed on the dummy in such
a position that one end is brought against the knife when the dummy is rotated so
that the exact length of paper is cut off.
When covering the narrow edges of the box lid, the broad roll of paper is
replaced by a narrow roll of the required width, the operation being the same as
that for the box proper.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
:-
1. In a paper box covering machine wherein the boxes to be covered are
carried on a rotatable dummy or former and wherein the covering paper is
automatically cut off from a length, mechanism whereby both the former and the
severing mechanism are operated from a treadle in such a manner that the severing
mechanism renains inoperative notwithstanding the movement of the treadle until
such time as the rotation of the former is practically completed, substantially as
described.
2. In a machine of the kind described, operating the dummy by means of
a treadle through the medium of a connecting rod, crank, toothed wheel and
pinion, and the knife by means of the said treadle through the medium of an

page_text: arrangement of links and levers in such a manner that the dummy makes nearly a
complete revolution before the knife is operated, substantially as, and for the
purpose, herein before described.
3. The combination and arrangement of parts forming the improved machine for
covering boxes with paper herein before described and illustrated in the accompanying
drawing.
