Improvements in Machinery to be Used in connection with the
Manufacture of Metal-edged Cardboard and other Boxes.
I, MORITZ HEINEMANN, of Bielefeld, Prussia, in the Empire of Germany,
Manufacturer, 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 machinery to be employed in pressing the metal
binding strips or edgings onto the edges of cardboard, paper, wood and other like
boxes.
Figure 1 of the accompanying drawing represents a vertical section of the
machine, but with the pressing tool and box rest as well as under part with the
treadle in elevation.
Figure 2 is an elevation of the back of the machine.
Figure 3 represents an elevation of the left hand side of the machine, connected
to an arrangement for cutting off the metal strip before coming into the pressing
tool.
Figure 4 represents an elevation of the back and a
arrangement in Figure 3.
partial section of the latter
Figure 5 is a front elevation of the pressing tool, in which is fed a length of
edging that is to bind the edge of a box.
Figures 6 and 7 show a holder for the strip.
Figures 8, 9 and 10 represent an elevation of the right hand side an elevation of
the back, and a topside plan of a channel for the strip which, together with the
pressing tool is carried on the slide.
The same letters of reference indicate corresponding parts in Figures 1 to 10 of
the drawing.
a is a pressing tool or stamp mounted at the lower end of a slide b, which
makes a vertical movement between guides c', affixed to the front of the main
framing c of the machine. This tool cousists of a body part a', having a
V-groove a, cut along its underside, with the sides corresponding to the inclination
which the sides of the box take when placed on the rest d, which carries the box
being bound and can be adjusted lengthwise by sliding the same into or out of the
hole in the body of that machine. Along either side of this groove a', run rest
ledges a', upon the top-sides of which the portion of edging strip contained within
the tool lies. These rest ledges which are somewhat of an L cross section, are
each carried by 8 pair of arms a, jointed at a to the upper part of the tool, and
are normally pressed up against the sides of the said tool, so as to cause the rest
parts a to come under the groove a', by flat springs a', made fast at one end to the
tool body, but with their free ends bearing agaiust the backs of the rest and
tending to force them together.
The vertical downward movement of the tool-carrying slide 6 is effected through
& 8ystem of levers.
is a treadle lover pivoted at f, to the back of the lower part of the standard o
supporting the framing of the machine, and having jointed to its middle part a
coupling rod, whose upper end carries a cross rod f, to the ends of which are
jointedly connected a pair of links. or arm f4, disposed one on either side of the
framing and being jointed at f' to the outer ends of the principal levers 9, 9',
mounted on the ends of the main axis g' which rans along the top of the back part
of the frame.

page_text: The mechanism for giving the movement to the said slide is as follows:-
Bolted to the middle part of the principal axis o' is a lever i, forming with the
double links i, a knee joint, capable of straightening on the arins g, g' making a
downward movement. The links i, are jointed at, to the tail of a lever j, which
is pivoted at, to the framing, and has a curved nose end, and which is capable
of exerting great pressure upon the slide.
The return or ascending movement of the slide is effected by springs (not shown)
attached to a fixed part of the framing at one end and to the said slide at the other
end. The binding strip or edging in which may be of the kind described in the
Specification of Letters Patent granted to me and bearing date the 19th day of
June 1895 No. 11807 or of any other suitable variety, is fed into the pressing tool
by feed mechanism.
The said feed consists of a channel or gutter a; in the drawing it has the
U form. The feeder o is guided by trunnions or pins on the sides of the same
taking into side slots n' in the gutter. The said feeder has upon the underside
of its horizontal arm o, a tooth or teeth o', or its or their equivalent, adapted to
take into holes in, or otherwise engage with, the strip and feed the same forward
into the tool to any desired extent.
This extent of feed is regulated by a lever r, in the following manner. The
lever, is to be turned on the principal axis g. The curved arm which
carries by and adjustable in the box end of the part of the lever r,, has a
pin, which is driven by a prolongation of the lever i. If the tool is being
depressed by the trendle, the lever i with its prolongation is moved in the
direction of the arrow (Figure 1) and through the medium of the pin
curved arm moves the lever r, r, in the same direction.
of the
The vertical arm o' of the feeder o is united with the lever by a bar oº and
therefore the whole feeder is drawn back by the lever r, till the tool has been
depressed to its lowest extent and comes upon the work lying on the rest d.
By this movement of the lever r, the pin has been taken up by the hook-
ended spring arm and is held there, till the tool returns again to its highest
position when the pino, of the liuk runs under the extension 1 of the spring
hook arm h, and the pin is thereby set at liborty. By a springs, which has
been distended by the descent of the tool, the arm and therefore also the
feeder o is brought back in its first position, feeding the strip m with it into the
tool. Now the whole machine is again in its first position and the descant of
the tool as well as the feeding of the metal strip can be again repeated in the same
manner.
The length of the feed is dependent upon the position of the pin. Therefore
the curved arm can be adjusted in the end of the lever, so that the
arm moves the latter and with it the feeder o, a greater or less extent as is
wished.
In all cases the pin is engaged by the book end of the spring arm h, when the
tool is in its lowest position because also in this moment the arm has reached its
extreme position in the direction of the arrow (Figure 1). After the return of the
feeder o and the cutting off of the strip, it might easily happen that the metal
strip m would be carried back into the gutter by the teeth o of the feeder o,
and in order to prevent this, an arrangement has been devised consisting in
A spring-arm with forwardly inclined teeth which catch the strip and
prevent same moving back, but which aro automatically lifted by a wiping
action, out of engagement with the holes in the strip on the same making a
forward movement.
In many cases it is well to slightly bend the metal strip m before it is fed
forward into the tool as by so doing greator strength is given thereto.
The heading of the strip into a shallow V figure before feeding into the tool
may take place in the manner as is shown in Figures 3 and 4 of the drawing.
Situated behind the channel or gutter and lying upon a foundation p carried by
the frame c, is a fixed har u, slightly she-V grooved on its top face whilst pivoted to

page_text: the foundation plate p, are a pair of angle levers t, t, whose arms carry a second
bar t, he-V faced on its underside and presented to the she groove in the bar u,.
between which said bars the edging strip is fed.
Made fast to the principal axis is the arm t, which presses against the arms t
of the angle lever t, t, (which are coupled together by the link t) and therefore.
the upper strip is made to approach the under strip u, and bend's the edging
metal which is lying between them on the said axis being turned to depress
the tool by the treadle. Sometimes it is desirable to move the channel or
gutter upwards and downwards with the tool. By this the feeding of the metal
strip into the tool can take place during the whole of the upward movement of the-
said tool.
This feed consists of a channel or gutter n, carried upon pegs n', at its ends,.
suspended from spring arms n', attached to a carrier bar n³ connected to the lower
part of the slide or the tool and through sleeves n in which the said pegs n',.
take. It will be observed that during the descending movement of the slide, the
gutter is brought to rest by coming upon the top of the bed of the machine
before the tool completes its downward movement, and that this is admitted by
the flexibility of the springs n, by which the gutter is suspended from the carrying
rod n³.
The arrangement of the levers for trausporting the metal strip can be the same.
as described or any other.
The inward end of the tool carries a knife blade which, on being brought down
to a like blade carried by rest d, outs off the length of edging metal fed into the
tool.
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 is:-
First. In machinery for edging card-board and like boxes with metal, imparting
a powerful descending movement to the slide carrying the pressing tool by a knee
joint and lever, actuated by a treadle or equivalont, and with the nose or end of
the said lever transmitting a powerful pressure to the said slide, substantially as
and for the purpose described and set forth in Figures 1 to 10.
Secondly. In machinery for edging card-board and like boxes with metal,.
feeding the edging strip into or below the pressing tool through a guide, gutter
or channel, either made a fixture with the frame of the machine or making an..
ascending or descending movement in common with the press tool and containing-
within it the means for feeding the said strip, substantially as described and set
forth.
Thirdly. In machinery for edging card-board aud like boxes with metal, passing
the edging strip into or below the tool by the feeder constructed, arranged,
operating and actuated substantially as described and set forth in Figures 1 to 10.
Fourthly. In machinery for edging card-board and like boxes with metal, the
means for preventing back movement of the metal strip during the cutting off of
the same during the return movement of the feeder, substantially as herein
described and shown in Figures 6 and 7.
Fifthly. In machinery for edging cardboard and like boxes with metal, the
means for bending the metal strip before it enters into the channel or gutter of the
feeding mechanism, substantially as described and set forth.
Dated this 13th day of April 1896.
