COMPLETE SPECIFICATION.
Improvements in Appliances to be used in Connection with the
Production of Metal Edged Paper 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 :-
In order to construct boxes from cardboard, wood and the like the sides are
united at the edges by pressing or driving in notched strips of metal by means
of a press or clenching machine. In order that the sides may not become dis-
placed during this process it has hitherto been necessary for them to be held
firmly on the block by hand. This is quite practicable in the case of small boxes
but not in the case of larger ones and for this purpose the clenching machine
requires to be provided with a special contrivance to hold the sides.
Figure 1 is a front elevation of a clenching press provided with an adjustable
support for holding the box sides constructed in accordance with my invention.
Figure 2 represents upon a large scale, a plan of one of the holders which
is adjustable upon a rod proceeding at an angle from the back of the machine.
Figure is a view showing the die of the press and the holders in section.
According to this form, the attachment consists of angle pieces b, which are
adjustably attached on either side of the block or die P, of the machine. The
box sides W rest on the one web 1, of the angle piece and are retained in
position by the other arm 62, which forms a stop see Figure 3 of the accompany-
ing drawing. In this view, P is the block or die whereon the top edges of the
box sides W rest while below they are supported by the adjustable angle pieces.
The connection of the said angle pieces b, with the machine is effected in any
suitable way, two methods being illustrated in the accompanying drawing. Of
the machine itself only the pillar S is shewn which supports the upper part and
to which the block P is attached. In the slot So of this pillar is the treadle.
In the arrangement of which Figures 1 and 2 shew the pillar and the means of
connecting the angle pieces with it, the said angle pieces b, are attached to
slides h, which move along the arms a¹, of a rod a, bent to a right angle and
resting upon, or secured to the back of, the die block, and these slides can be
fixed at any point of the said rod.
If the angle pieces 6 are long they can be supported by a strut or bracing
piece c, see Figure 2.
The contrivance is used as follows:-
First the angle pieces 6 are adjusted to the dimensions of the box and the
slides h, made fast by screws s. Then the box sides W are laid on b, and the
block P, the metal strip m is pressed or driven in on the meeting edges and
so the sides are connected.
In the arrangement shewn in Figures 4 and 5 there is a plate Q on the
pillar S of suitable shape, which may naturally differ from the shape illustrated.
This plate has an angular slot 2, (see the section view in Figure 5) in which
there are fitted square pins b¹, which are provided with a thread and nut r, and

page_text: which are attached to the angle pieces b, and can, after adjustment to the
dimensions of the box, be held fast by tightening up the nuts r.
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 a machine for securing together the edges of the sides of cardboard,
wood and the like boxes, by means of notched metal strips, the employment of
adjustable angle pieces on which the box sides rest and are retained substantially
as described and set forth.
Secondly-In a machine for securing together the edges of the sides of card-
board, wood and the like hoxes, by means of notched metal strips, the employment
of angle pieces or rests carried by slides which can slide and be fixedly adjusted
on a pair of arms carried by or resting upon the lower die block of the machine,
substantially as described and set forth."
Thirdly: In a machine for securing together the edges of the sides of card-
board, wood and the like boxes, by means of notched metal strips. connecting the
rests or angle pieces with the slotted plate in the slot (g) of which the said rests
or angle pieces can slide and be fixedly adjusted, substantially as described
and set forth.
Dated this 29th day of March 1899.
