Improvements in Machinery for Securing Metallic Strips to the Edges
of Cardboard and other Boxes,
I, MORITZ HEINEMANN, of Bielefeld, near Hannover, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what man-
ner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to machinery or appliances for securing metallic bind-
ing strips to the edges of cardboard, wood and other similar boxes and has for its
object, to simplify the construction of such machines and to provide the same
with an efficient automatic and adjustable mechanism for feeding the edging
metal, in pre-determined lengths, into the space between the dies or tools by
which it is applied to the edges of a box.
Figure 1 of the accompanying drawings represents, partly in elevation and
partly in section, a machine constructed in accordance with my invention. A
portion of the side walls of the body is broken away to show more clearly the
arrangement of the feed mechanismi.
Figure 1 is a detail part of the machine shown in Figure 1.
Figure 2 is a plan of the bed of the machine showing a portion of the feed
mechanism.
Figure 3 is a topside plan of the machine, showing the system of levers by
which the movement of the operating lever is conveyed to the tool or die slide
and the arm which actuates the feed mechanism.
Figure 4 is a diagramatic view illustrating the movement of the said systemi
of levers.
The same letters of reference indicate corresponding parts in the several
figures of the drawings,
In the machine illustrated in the drawing, the attachment of the notched
metal edging strips to the corners of a box is effected by a press or stamp which
is drawn up by a spring and a combination or system of jointed levers. This
consists of the treadle-lever moved by the treadle and the pressure-lever con-
nected with it by a link. A projection on the pressure-lever engaged the press
on the inner side and not on the outside as in previous machines of this class.
The treadle-lever is fixedly attached to a feed arm, by the swinging motion of
which the metal strip is brought forward in different lengths as required.
Mounted in the top of the frame a, is a pin b, supporting the outer end
of the pressure lever c, which is connected by means of the links d, with the
treadle-operated lever e, from the forks of which hang the coupling rods f, which
are connected with the treadle t, working on the pillar through the medium
of the rod t¹, and the cross piece 2, (ride Figures 1 and 1). When the treadle,
is depressed, the jointed levers are made to gradually leave the upper posi-
tion c, d, e, shown in the diagram Figure 4 and assume the lower position c, d,
el, and the projection or acting portion e, of the lever e is caused to bear upon
the upper parts, of the press s, which is guided in the frame, and force the same

page_text: downwards, whereupon the tool at its lower end presses the notched metal strip
into the corner of the box, which is supported upon the angular sectioned bottom
die or bed. The return movement of the stamp is brought about by the
spring, disposed between it and the pin band that of the treadle by the
spring, which connects it with the pillar. r is a guide channel, with its front
end jointedly connected to the rear of the press at 2, and the rear end (by means
of a slot, working over the pin ) to the frame «, into which channel the
notched metal strip is introduced from a roller (not shown) and in which it is
passed forward. m is a carrier or conveyor provided with two spring pegs
adapted to engage in the holes in the strip when the forward movement of the
carrier takes place, simultaneously with the rise of the press and carry or feed
the strip forward. When the press descends, the pegs are withdrawn from the
holes in the strip and the carrier makes a movement to an extent equal to the
length of the next strip of edging metal to be fed. The to-and-fro feed motion
of the conveyor or carrier m is effected by a lever which is either made in one
piece with the lever c or is attached fixedly to the same axle. This lever is
forked, as shown in Figure 2, and between the branches of it, a block k, revolves,
in which a rod jointedly attached to the carrier m, slides. This rod is provided
with a fixed stop o and an adjusting collar q. Behind the former is a small
buffering spring i, to prevent shock or jar being set up when the rod is caused
to make its forward traverse or feed movement.
When the press is depressed, the feed lever n, assumes the position represented
by dotted lines in Figure 1 and marked n', and it is evident that on the press
commencing to again ascend, the lower end of the said arm must have a certain
amount of free or idle movement between the adjustable stops o and q, before
it comes against the spring i and commences to propel forward the rod 1, in
order to feed the desired length of edging metal under the press tool prior to its
application to the edge of a box resting on the lower die.
The freedom of movement is provided in order to permit (before the feed
mechanism becomes operative) of the press tool first lifting to such a distance
above the bed, rest, or lower die that there shall be no impediment to the feeding
of the said strip into its assigned position underneath the upper press tool,
prior to being cut off and applied to the box edging on the next descent of the
press, during which latter movement the carrier or conveyor is taken back empty.
In order to adjust the machine to feed varying lengths of edging metal, it is
only necessary to alter the position of the adjusting collar q, upon the rod /, rela-
tive to the fixed stop, but the arrangement of the system of operating levers
and the throw of the feed arm are such even when the greatest possible length
of strip is being fed forward as to be able to freely advance the said length
without fouling the press tool.
By the herein-described system of levers for communicating the movement of
the operating treadle to the press slide and the mechanism for ensuring the un-
impeded feeding of the strip or edging metal under the upper press tool, the
machine is much simplified and rendered steady and positive in its working:
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
First In machinery for applying or affixing metal edgings to cardboard,
wood and like boxes, operating the press or stamp by a pressure lever, which
has a projection or acting part bearing upon the inner side of the press slide,
and is operated by a system or combination of levers arranged and working
substantially as described and set forth.
Secondly feed mechanism for machinery to be used in affixing metal
edgings to cardboard, wood and like boxes, consisting of an arm arranged in
connection with the press-operating mechanism of the machine, and acting in
conjunction with a strip feed rod and carrier or equivalent, with the throw of

page_text: the said arm being so regulated that the feed of the said strip, effected on the
press making a rising movement, only commences when the press is so high as
not to impede the movement of the strip, substantially as described and set forth.
Thirdly A machine for securing metal edgings to cardboard, wood and like
boxes, having a hand or foot operated system of levers, of which a pressure lever,
such as c, bears upon the inner side of the press to impart the downward move-
ment thereon, whilst a feed arm, such as n, connected with the said operating
levers, is made to have a swinging movement, which is imparted to a carrier (m)
through the medium of a jointed rod () provided with a fixed stop (6) and an
adjusting collar (q) between which the end of the feed arm is capable of an
adjustable amount of idle movement, the arrangement being such that when the
press descends, the carrier goes back empty, but when the press is again raised,
the carrier, with a length of edging metal, is pushed forward but not until the
press is raised to such a height as to offer no impediment to the strip, substan-
tially as herein described and set forth.
