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:-
This invention relates to a method and apparatus for the production of composite
boxes and cases, out of cardboard or the like having their sides joined by means of
metal clamps. In order to increase their strength the projecting teeth of the metal
clamps penetrate the cardboard, the clamps having been given the requisite shape as
hereinafter described. The teeth are inserted through slits previously cut in the
cardboard and the points of these projecting into the interior of the box, are then
clenched so that they lie close and firm against the cardboard sides of the box. For
the bending to shape of the metal clamps as well as for the clenching of the points
against the inside of the cardboard, the inventor has devised apparatus. The machine
for bending the flat metal clamps into shape is as follows. A shaft driven by hand
or other power bears an eccentric provided with a projection at each side which sets
a plunger and the stamp attached thereto in reciprocating motion when the said shaft
revolves whilst the side projections act on two lever arms. These lever arms which
are attached below and which are also acted on by a spring, open and close at every
revolution of the shaft. The matrix adjustable by wedges and screws is impelled
upwards and downwards by means of a lever arin propelled by an eccentric fixed
upon the main shaft.
The metal clamp to be shaped is laid upon the matrix when the saine is in the
proper position, upon the descent of the lever arm caused by the spring and the
resulting contact of the same through a slit, with the matrix, the latter, together with

page_text: the clamp lying on it is carried under the stamp and the clamp (which may obviously
be shorter, but must in no case be longer than the matrix) receives by the blow of
the stamp and of the two lever arms, the requisite bent form, and as soon as the
stamp begins to ascend and the arms open again the clamp falls in consequence of the
inclined position and is delivered bent to shape, through the open frame of the
machine into a box below the same.
The apparatus devised for the purpose of clenching the ends of the metal clamps
after they have been inserted in the cardboard boxes for the purpose of securing the
sides of the same is as follows.
Upon the main frame an eccentric shaft is secured so that it can revolve, the said
shaft is held in the frame by a screw and is enclosed by two semicircular concave
covers. These covers, to whose upper straight portions steel cheeks are secured by
screws, can be raised and lowered and the checks consequently separated and placed
together by means of a lever.
When the covers are raised the vertically placed lever is depressed whereby the
checks are pressed apart by their spring and open as wide as the stop pins admit.
When the cheeks are in this position the side pieces of the box under operation in
which the metal clamps have been previously inserted are placed between the cheeks
and the frame, after which the lever is returned to its original position by means of a
smart blow and the cheeks come together, pressing down the projecting points of the
clamp closely against the inner surface of the sides. The use of such metal clamps
and of a similar method of operation especially the shaping and securing of the
clamps by the described machines possesses the great advantage that not only is there
attained exceptional firmness and elegance of joining, but that the cut cardboard for
the boxes can be forwarded in the flat state being of course properly shaped and
provided with the requisite slits for the metal clamps and the consumer can put the
boxes together at his own place of business by means of the above described machine,
quickly and cheaply.
The metal clamps are of different sizes and have more or less points according to
requirements.

of Boxes of Cardboard or the like.
A communication from abroad by JACOB GEIGER, of Stuttgart, in the Kingdom of
Wurtemburg and Empire of Germany, Manufacturer.
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 :-
This invention relates to a method and apparatus for the production of composite
boxes and cases out of cardboard or the like having their sides joined by means of
metal clamps.
In order to increase the strength of cardboard boxes the sides are fastened by
metal clamps o (Figure 9) at the edges where they come together.
The projecting teeth of the metal clamps penetrate the card board, the clamps
having been given the shape shown at o¹ and o², Figures 9 and 9: the teeth are
inserted through slits previously cut and the points of these projecting into the
interior of the box, are then clenched so that they lie close and firm against the
cardboard sides of the box. For the bending to shape of the metal clamps o as well
as for the clenching of the points against the inside of the cardboard, the inventor
has devised apparatus as follows (Figures 1 to 8).
Referring to the accompanying drawings.
Figures 1 and 2 show a machine for bending the flat metal clamps o into the
shapes o' and o Figures 9b and .9°.

The shaft w driven by hand or other power bears an eccentric d provided with a
projection at each side which sets the bar and the stamp p attached thereto, in
reciprocating motion, when the shaft w revolves, whilst the side projections act
on the two lever arms e e, these lever arms which are attached at ee and which are
also acted on by a spring open and close at every revolution of d. The matrix m
adjustable by wedges and screws is impelled upwards and downwards in the direction
indicated by an arrow by means of the lever arm secured at i upon which act the
eccentric g fixed upon the shaft w.
The metal clamp o to be shaped is laid upon the matrix m when the same is in the
position indicated in dotted lines in Figure 1. Upon the descent of the lever arm h
caused by the spring k and the resulting contact of the same through slit with the
matrix m the latter together with the piece o lying on it is carried under the stamp p
and the clamp (which may obviously be shorter, but must in no case be longer than
the matrix) receives by the blow of the stamp and of the two lever arms e e the

page_text: form o² shown in Figure 9, and as soon as the stamp begins to ascend and the
arms e e open again the clamp falls in consequence of the inclined position and is
delivered bent to shape through the open frame of the machine into a box below the
same. The apparatus shown in Figures 3 to 8 is devised for the purpose of clenching
the ends of the metal clamps after they have been inserted in the card board boxes,
for the purpose of securing the sides of the same upon the frame A the eccentric
shaft is secured to s and s¹, so that it can revolve, the said shaft is held in the
frame A by a screw z¹ and is enclosed by the two semicircular convex covers ??¹.
These covers to whose upper straight portions the steel cheeks t t¹ are secured by
screws can be raised and lowered and the cheeks consequently separated and placed
together by means of a lever q.
When the covers are raised, the vertically placed lever q (Figure 3) is depressed
in the direction of the arrow whereby the cheeks are pressed apart by the spring vl
and open as wide as the stop pins y y admit (Figure 3). When the cheeks are in
this position the side pieces u u' of the box under operation in which the metal
clamps o² have been previously inserted are placed between the cheeks and the frame
as shown in Figure 5 after which the lever is returned to its original position by
means of a smart blow and the cheeks t t come together pressing down the projecting
points of the clamp o' closely against the inner surface of the sides u u¹ as shown in
Figure 8.
The use of such metal clamps and of a similar method of operation, especially the
shaping and securing of the clamps by the described machines possesses the great
advantage that not only is there attained exceptional firmness and elegance of joining,
but that the cut cardboard for the boxes can be forwarded in the flat state, being of
course properly shaped and provided with the requisite slits for the metal clamps,
and the consumer can put the boxes together at his own place of business by means
of the above described machine quickly and cheaply.
The metal clamps are of different sizes and have more or less points, according to
requirements.
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 :-
1. A machine for bending metal clamps to the shape o² represented on Figure 9
substantially as described and illustrated with reference to Figures 1 and 2 of the
accompanying drawings.
2. A machine for bending down the clasps projecting inside the cardboard boxes
and forming part of the clamps of destined to connect the lateral parts of the said
boxes, substantially as described and illustrated, with reference to Figures 3 to 8 of
the accompanying drawings.
