PROVISIONAL SPECIFICATION
Improvements in Machinery for Making Cardboard Boxes.
I, WILLIAM CROSLAND of New Street Miles Platting Manchester do hereby
declare the nature of this invention to be as follows
:-
The object of this invention is to bend a piece of cardboard or common straw-
board into the form required in making boxes without cutting scoring breaking or
otherwise weakening the material but leaving the corners of the box as strong as
any other part.
To accomplish this I provide an iron stand with feed table similar to an
ordinary roller scoring machine, on a shaft in front of this table I place one or
more circular knives or creasers, the edges of which are not sharp enough to cut
fix other
the material, on another shaft at a suitable distance above the other,
knives in couples; that is for each knife on the bottom shaft I place two on the
top shaft in such a manner that each bottom knife works between two top ones, the
two top knives are by a peculiar arrangement fixed in a diagonal position, that is
to say, they are wider apart at the top than at the bottom where they aproach the
bottom knife. The material is fed in between the bottom & top knives which
are both revolving in such a manner as to draw the material forward, the bottom
knife forcing it between the two top knives.
The peculiar action of the top knives cause them to press the material tightly on
to the bottom knife & prevent it from breaking or cracking. When the board
has gone through the machine it has a ridge raised on one side by the pressure of
the top knives, & a nick or channel on the other made by the bottom knife being
pressed into it, the board can then be bent square, allowing the projection to go
inside the box. I have spoken of top & bottom knives for convenience of
explanation. I wish it to be understood that my claim is for placing the shafts
in any position so that one knife can be working between the other two.

page_text: position on the shaft. The two ends of shaft A are supported by the two
frames C C in which it revolves and is put in motion by a pulley or gearing at
one end.
Above the shaft A is fixed a strong bar D running parallel with it & is
bolted or otherwise fixed to the two frames C C at each end. E E are two
brackets fixed on the bar D by a bolt in a longitudinal slot so as to allow them to
be moved from end to end, or fixed at any position on the bar. These brackets
project downwards below the shaft A not vertically but diagonally approaching
nearer to each other at the bottom. In the lower part of this bracket is a large
hole into which the bosses of the squeezers are fitted in such a way as to allow
them to revolve freely on shaft A, yet to be held in a diagonal position by the
brackets E E. Below shaft A and attached to frames C C is another shaft F
parallel to shaft A and which can be geared to shaft A though this is not always
necessary.
On shaft F is a wheel G with a flat rim as shown in Fig. 1 & 2 with projection
which runs between the discs or squeezers B B.
H Fig. 2 is a feed board from which the work is fed into the machine. The
boards as they are fed in pass over the wheel G in the centre of which is fixed a
thin creaser which forces the board between the two squeezers. As the squeezers
draw near to each other they squeeze the board against the creaser in such a
manner as to raise a ridge on the top side of the board as shown at M Fig. 3.
The board can then be bent up as shown at N Fig. 3.
Having now described the nature of my invention, I wish it to be understood
that what I claim is
The use of two discs as herein described fixed in a diagonal position so as to
come nearer to each other as they approach the material and thus raising the
board into a ridge as shown on Fig. 3.
