Cardboard or other Material at an Angle to each other.
I, JASPER WETTER, of the firm of Fairfax & Wetter, Patent Agents and Consulting
Engineers, of 433, Strand, London, do hereby declare the nature of this invention
to be as follows:-
This invention relates to machinery for stitching together sheets of cardboard or
other material at an angle to each other, and has for its object to adapt such
machines for the manufacture of round or polygonal boxes.
The machine employed for the manufacture of round or polygonal cardboard boxes
may be similar to those described in the patents specifications No. 16,137 of 1884
and No. 7961 of 1886, except that the saddle and clenching apparatus are constructed
as follows:
Instead of the vertically movable saddle A. shown in Fig. 12 and 13 of speci-
fication No. 16,137, 1884, I employ a curved beam carrying at its upper end a
rounded disc or plate which serves as a supporting base for the hottom of the round
box. The upper part of the said beam, and the said disc form a right or a slightly
obtuse or acute angle to each other and slant downward in opposite directions from
the axis of the machine (or the vertical line of motion of the staple-driver).
The lower part of the said beam is curved backward toward the line of motion of
the staple-driver, so as to form with the upper part an angle or horse-shoe. The
said beam is provided with a guide plate adapted to be raised vertically during the
driving and clenching of the staple, the staple clenching mechanism being set in
action by means of a connecting rod placed parallel with the upper half of the beamn
at the inner side thereof, a bell crank lever connected at one end with the lower end
of the said rod and actuated at the other end by a link or screw stud or other device
which receives its impulse from the operating lever connected with the treadle. The
DQ27

page_text: upper end of the connecting rod may be pivoted to an oscillating lever which in its
turn is connected with the guide plate by a pin.
The supporting disc at the top of the curved beam is preferably semi-circular, but
may have any other suitable shape according to the shape of the box to be made, and
is made exchangeable.
For connecting the circular, oval, or polygonal bottom of a cardboard box
with the cylindrical side of the same, the cylindrical part of the box is placed
over the beam, the axis of the cylinder being parallel with the axis of the
upper part of the beam, and therefore at an angle to the vertical, and the
bottom is placed upon the supporting disc in such a manner, that the edge of the
cylinder coincides with that of the bottom, or that one of them extends a little beyond
the other. Subsequently the wire staple is driven through the side and bottom, and
the ends of the staple are clenched in the interior of the cylinder, by means of the
clenching mechanism situated in the upper part of the curved beam.
The body or side of the box may be cylindrical or polygonal, or it may
form a truncated cone, connected with the bottom either at the narrow or at the
wide end.

Cardboard or other Material at an Angle to each other.
I, JASPER WETTER, of the firm of Fairfax and Wetter, Patent Agents and
Consulting Engineers, of 433, Strand in the city of Westminster, do hereby declare
the nature of the said invention, a communication to me from abroad by the firm of
C. L. Lasch & Co., Engineers, of Reudnitz-Leipzig, Saxony, and in what manner
the same is to be perforined, to be particularly described and ascertained in and by
the following statement :-
This invention has for its object to adapt wire-stitching machines for the
manufacture of round or polygonal card board boxes, and more especially for
securing the bottom of such boxes to the side by means of steel-wire.
In the following description reference will be made to the annexed drawings in
which Fig. 1 is a side elevation of a wire-stitching machine embodying the invention,
while Figs. 2 to 5 represent the clenching apparatus on a larger scale, Fig. 2, being a
front elevation, Fig. 3, partly side elevation and partly vertical section, and Fig. 4, a
plan of the same, after removal of the work-supporting disc. Fig. 5 is a section along
line W-W of Fig. 2. Figs. 6, 7, and 8 represent sections of boxes, which may be
made by this machine. The machine may be similar to that described in the
specification of the English Patent No. 16,137 of 1884, with the exception of the
saddle and clenching apparatus, which are constructed as follows:-
Instead of the vertically movable saddle A shown in Fig. 12 and 13 of the English
patent specification No. 16,137 of 1884, I employ a curved beam T carrying at the
top a supporting disc P, and rigidly connected at the bottom with an upright arm or
guide plate t. This arint is guided vertically by a sleeve u, as shown in Fig. 1 or
by other convenient means, and is pressed upwards at the required moment by the
motion of the wedge-shaped extremity of the horizontal rod v operated by the lever V
(Fig. 1). As in the earlier machines made by C. L. Lasch the extremity of the rod e
is situated between a pair of friction rollers 1, 3, the bearing of the lower roller
being secured to a stationary support, and vertically adjustable, while those of the
upper roller are fixed to the arm t. In the present case, the roller t¹ has its bearings
in a recess of the arm t, while the lower roller is held in a shackle ³, provided with
a screw spindle t which allows the roller 2 to be placed higher or lower by turning
the hand wheel to. The lever T is shaped in cross section as shown by Fig. 5, and
carries at the top the clenching mechanism which is movable vertically between a
pair of guide plates g, g secured to the side of the beam T. (see Fig. 9).
The plate carrying at the top the clenching plates is connected at the bottom with
an oscillating lever h pivoted to the side of the beam T. This lever is connected by a
pin or stud with the upper end of a rods joined at the lower end to an angle lever
having its fulcrum at the back of the beam T, as shown in Figs. 3 and 4.
The angle lever is in contact with the extremity of an adjustable screw stud
secured to the operating lever o.
P

page_text: As shown in Fig. 2, the upper part of the beam T is inclined, and provided with a
curved disc P made exchangeable, so as to suit the shapes and sizes of the boxes to be
made. This disc or work-supporting plate is preferably made of sheet metal, circular
It may have a flange or rim

projecting downward from the edge of the plate.
As shown by Fig. 2, the curved beam T is situated almost entirely on one side of
the vertical centre line, while the vertical guide-piece t extending upward from the
bottom of the beam T is situated a short distance behind the beam T, and in the plane
of symmetry (or middle-plane) of the machine.
To facilitate the lifting of the beam T, the upper end of the guide-piece may be
connected with one or more helical springs suspended from the principal arm or
goose-neck of the machine frame.
The plate P has a rectangular slot to receive the upper end of the beam T, so
that the face of the beam T is flush with the upper surface of the plate P, the latter
being secured to the side of the beam by a short angle plate pl and screws.
is a detached view of plate P.
Fig. 10
To the upper end of the vertically sliding plate fare pivoted the two symmetrically
placed clenching plates, which by the up motion of the plate fare pressed against the
projecting ends of the staple and clench the same.
The construction and operation of the clenching plates and accessories which
constitute the clenching mechanism proper, is similar to that described in the earlier
patent specifications of the said C. L. Lasch, and will not, therefore require a
detailed explanation.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:
--
1. In wire-stitching machines, the combination of an inclined beam free at the
upper end and adapted to describe a short reciprocating motion to and from the
staple forming head, with a supporting plate secured to the upper end of the said
beam, clenching mechanism secured to the upper end of the beam underneath the
supporting plate, and mechanism for automatically operating the clenching mechanism,
substantially as described.
2. In wire-stitching machines, the combination of inclined beam T having a guide-
plate or arm t, with supporting plate P, clenching mechanism secured to the upper
part of the said beam underneath the plate P, mechanism for imparting to the
beam Ta periodical up and down motion, an operating lever O, and mechanism for
transmitting the motion of the lever O to the clenching mechanism, substantially
as described.
3. The combination of beam T, clenching mechanism and slotted supporting
plate P, with operating lever O, and lever mechanism p, r, s, h, substantially as
described.
4. In machines for stitching round boxes, a supporting plate P arranged and
shaped substantially as described.
5. In machines for stitching round boxes, the position and shape of beam T and
arm t, substantially as described.
6. In machines as described, the means for transmitting motion from the operating
lever O to the clenching mechanism, substantially as described.
