I, WILLIAM PHILLIPS THOMPSON F.C.S. of the Agency for Foreign Patent
Solicitors, 6, Lord Street Liverpool in the County of Lancaster, and 323 High Holborn
in the County of Middlesex Civil Engineer do hereby declare the nature of this
invention to be as follows :-
The present application has for its object certain improvements with apparatus
described on the inventor's prior patent No. 3444 of 1886. As has been already set
forth in the above patent it is necessary in the construction out of card board and
similar materials, of boxes and the like, whose sides have to be hent up to have
grooves or channels rolled into the material at the lines where the bending is to take
place. As however there is great variation in the composition of the various kinds of
card-board employed, it is frequently preferable not to form the grooves by roller
pressure but to scoop or cut them out.
For this purpose the inventor has devised the following modifications in the machine
described in the above mentioned patent. From the frame of the roller machine the
upper roller together with its bearing and spring and screw is removed and a cross-bar
substituted. To this cross piece which is provided longitudinally with a swallow tailed
guide channel, there is attached the slit or groove cutting apparatus, the knife carrier
of the apparatus is adjustable along the cross piece both longitudinally and trans-
versely and holds by means of its lever bearing, the circular double edged knife. The
interval between the two blades of the knife may be regulated as required and
corresponds to the width of the strip to be cut out of the cardboard and the strength
of the material operated on. When the table has been adjusted at the proper height
by means of its guides the cardboard is passed to the circular knife over a feed roller.
The knife carrier and preferably also the circular knife always remain perpendicular

page_text: above the roller, and the cardboard under operation. In order to detach the strip of
cardboard partly cut out by the circular knife a lever knife between the two cutting
edges is made use of. The width of this blade must correspond to the interval
between the blades of the circular knife and consequently to the width of the strip of
cardboard cut by them: The knife is adjusted and held in place by a screw to prevent
the cut out strip of cardboard from getting fast between the knife blades, two other
blades are arranged, the cutting blade passes between the two circular blades in such a
manner that the cut out strip is pushed by the guide blade downwards and sideways
from the lever cutting blade, and falls down at the back of the apparatus. By means
of the above described mechanism a certain, rapid, and continuous working of the
apparatus is secured the space between the circular knife blades being always kept
clear and unobstructed by debris and the frequent necessity for readjusting or clearing
the knife is avoided. The cutting apparatus can be adjusted vertically and horizontally
along the cross bar by means of two screws.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., of the Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool in the County of Lancaster, and 323 High
Holborn, in the County of Middlesex, Civil 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 :-
The present application has for its object certain improvements in the apparatus
described in the inventor's prior patent No. 3444 of 1886.
As has been already set forth in the above patent No. 3444 of 1886, it is necessary
in the construction out of card board and similar materials, of boxes and the like,
whose sides have to be bent up (figure 8 of the accompanying drawing), to have
grooves or channels rolled into the material at the lines where the bending is to take
place. As, however, there is great variation in the composition of the various kinds
of cardboard employed, it is frequently preferable not to form the grooves by roller
pressure, but to scoop or cut thein out.
For this purpose the inventor has devised the following modifications in the
machine described in the above mentioned patent, which is illustrated by figures 3,4,5,6,
and 7, of the accompanying drawings.
From the frame a a of the roller machine, illustrated in figure 1, the upper roller b,
together with its bearing and spring g and screw f, is removed, and the cross bar q
(figures 3 and 4), substituted.
To this cross piece, which is provided longitudinally with a swallow tailed guide
channel, there is attached the slit or groove cutting apparatus (figures 5, 6 & 7); the
knife carriers of the apparatus is adjustable along the cross piece both longitudinally
and transversely, and holds, by means of the lever bearing t, the circular double-edged
knife u.
The interval between the two blades of the knife u, may be regulated as
required, and corresponds to the width of the strip to be cut out of the cardboard, and
the strength of the material operated on.
When the table n has been adjusted at the proper height by means of the guides m m,
the card-board is passed to the circular knife over the roller c, from which the discs e e
have previously been removed. The knife carrier s, and preferably also the circular
knife u, always remain perpendicular above the roller c, and the card board under
operation.
In order to detach the strip of cardboard partly cut out
lever knife v, between the two cutting edges, is made use of.
by the circular knife, a
The width of this blade

page_text: must correspond to the interval between the blades of the circular knife, and con-
sequently to the width of the strip of cardboard cut by them, and which is adjusted
and held in place by a screw. To prevent the cut out strip of cardboard from
getting fast between the knife blades, the two blades w and are arranged,
(see figure 6); the tongue w passes between the two circular blades in such a manner,
that the cut out strip is pushed by the blade a downwards and sideways from the
lever blade v, and falls down at the back of the apparatus.
By means of the above described mechanism, a certain, rapid, and continuous
working of the cutting blades and blade e, is secured, the space between the circular
knife blades being always kept clear and unobstructed by debris, and the frequent
necessity for re-adjusting or clearing the knife, is avoided.
The apparatus s can be adjusted vertically by the screw y, and horizontally along
the cross bar g by means of the screw y¹.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is:
In machines, substantially as described in patent Number 3444 of 1886, the
replacement of the upper roller 6 by a cross piece 7, to which is attached an apparatus s,
adjustable horizontally and vertically, for the purpose of cutting out grooves in the
cardboard or other material, bearing a double edged circular knife u, standing perpen-
dicular to the roller c, together with the lever blade v lying between the circular blades,
and the blades we and a, for the removal of the cuttings.
