IMPROVEMENTS IN WIRE-STITCHING MACHINES, OR MACHINES FOR BINDING BOOKS AND SIMILAR OBJECTS WITH METALLIC STAPLES
Year: 1884

page_text: I, HERBERT JOHN HADDAN, of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said Invention for "IMPROVEMENTS IN
WIRE-STITCHING MACHINES, OR MACHINES FOR BINDING BOOKS AND SIMILAR
OBJECTS WITH METALLIC STAPLES," a communication to me from abroad by Carl
Louis Lasch, of Rendnitz, in the Kingdom of Saxony, Gentleman, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
The improved wire stitching machine is represented in the accompanying
drawing Figs 1 to 28 and differs from similar machines by the simple manner in
which the same is operated, the motion of the treadle being sufficient to produce
the staple, to force the same through the paper and to clench the same.
A great advantage, as compared with other machines of this kind, consists in
the use of a bed or table arranged crosswise, so that no time is lost by withdrawing
the book or paper, while the machine may be kept continuously at work, the book
being directed from the left to the right across the table and subsequently
delivered.
Another substantial improvement consists in the supply of the wire by means of
rollers.
The machine may also be arranged for being operated by hand.
The machine works as follows: By a forward movement of the treadle mechanism
the toothed segment a connected with the same imparts motion to the wheel c
which is loosely mounted on the ratchet wheel b and provided with a pawl, whereby
the eccentric K' K" mounted on the same axle, is turned for half a revolution.
Thereupon the treadle with the segment is brought back into the original position
by means of the spring d. During this motion the lower segment e gears into
wheel, which is also loosely mounted and provided with a pawl, so that the
eccentric completes its full turn in one direction.
The levers and are operated by rollers travelling in curved grooves K' K" of
the eccentric.

page_text: To the lever g is attached by pin and slot the elastic lever i which engages into
the stamper plate k, and also the stop against which presses the lever o under the
influence of the spring m, said lever o serving to set in motion the plier or anvil n.
To the lever his attached the slide 9 provided with the knife and bending
plate p and with the pins 8, 8; furthermore the stop r and at the base of the frame
the rod t.
The forward motion of the treadle and the corresponding rotation of the eccentric
with grooves K¹ K" causes the levers g and h to move downward. The stop
presses the anvil n inward by means of the lever o, while the lover i simultaneously
presses the stamper plate k downward on the wire, which has been introduced, and
maintains the same.
At this moment the descending lever h, by means of the cutting and bending
plates pp attached to the slide q, cuts off the wire and bends the same over the
anvil.
During the further downward motion of the lever hand slide g, the lever o is
disengaged by the oblique stop r, and the anvil n over which the staple has been
bent is withdrawn by the spring m.
By the motion of the lever h, the wodge t has been drawn between the rollers u,
and the layers of paper to be stitched have been brought towards the front end of
the wire.
The lower roller u is controlled by the screw a¹ so that thin or thick layers of
paper can be stitched,
The lever g, by means of the plate k, now forces the staple through the paper,
after which the staple is bent by means of the bending apparatus, the lover.
connection v, and a stop attached to the treadle-rod.
The treadle thereupon recedes, all parts resume their previous position, and
during the ascent of the slide q the rollers are turned by means of the pins 8 8,
the angle lever xx, and the ratchet wheel y, whereby fresh wire is supplied from
a bobbin.
In order to stitch not only books from the side and through the fold, but also for
connecting the edges of paste board boxes with each other, the machine is modified
as follows.
Instead of the bed or saddle arranged crosswise and adapted to movo upward,
the machine is provided with an angular arm A having separate bending plates
operated by special mechanisms.
This arm is arranged in such manner at the base of the main frame, that paste
board of any depth may be placed on the same for the purpose of providing the
ends with staples.
In order, liowever, to ensure the proper formation of the angles of the staples,
the ordinary stamper-plate is replaced by a plate formed of two parts 2² 121 pivoted
on pins w and adapted to be drawn apart by spring B. The plates have rounded
edges D, which serve to push down the staples that have been finished above, and
from under which the anvil n has been withdrawn, so that the ends of the staple
arms are pressed towards the rounded recess E, whereupon the back of the staple
is placed on the angle edge of the pasteboard box and at the same time bent by the
oblique faces of the stamper and pressed into the walls of the box.
At the same time the binding plates of the arm A (which serve to bend the ends
of the staples) are set in operation by means of the following mechanism:
In the interior of the arm and at the front end thereof are pivoted on pins 8¹ 81
the bending plates q¹ q¹ having the shape of angle levers.
The plates are pivoted in order that their ends D may be pressed in such manner
against the ends k¹, k¹ of the staples, that the same are securely seized and pressed
smoothly and straight into the walls of the pasteboard box. This peculiar motion
of the bending plates q¹ is effected in the following manner.
By means of lever (which is operated by the intermediate picces G and H and
the pusher I) the part L is shifted up and down, whereby the pins s¹¹, the small
bearing r¹ and the bending plates q' are operated at the same time, so that, when

page_text: the bending plates descend, their ends press against the fixed oblique faces M,
whereby the plates are slightly spread apart, so that their corners first press against
the ends of the staples and bend the same; on further moving upward, the plates
receive support at z and firmly press the staples against the inner walls of the
pasteboard box.
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:
1. The combination of two toothed segments a, e, with tooth wheels c, f, carrying
pawls and mounted loose on shaft b' for the purpose of converting a circularly
oscillating motion into a continuous rotary motion.
2. A saddle-bed, laid crossways to the machine, and adapted to receive a short
upward motion of variable length by means of wedge-shaped rod t, friction roller u
and an adjusting screw a¹, for avoiding the forward motion and withdrawal of the
book to be bound.
3. The combination of slide q, pins 8, 8 and ratchet-lever mechanism x, x, for the
accurate feeding of the wire by means of rollers.
4. A wedge piece r secured to the lever h, and a lever o adapted to act on the
bending anvil in such a manner as to obtain the withdrawal of the anvil at
the required moment.
5. The combination of curved grooves or guides K¹ K" mounted on a shaft and
adapted to set in motion the entire mechanism.
6. An arm A, adapted to move up and down, and to carry the card-board boxes
to be stitched, in combination with levers F, G and H enclosed in the said arm and
serving to set in motion the bending plates q³.
7. A pusher composed of two parts p¹ p³ pivoted on pins w and held apart by
spring B, said pushers having inclined surfaces D adapted to press the bent staple
into the recess E and into the corner of the cardboard box.
8. A pair of clenching plates q¹ q¹ placed in the arm or hollow platform A and
adapted to be pressed apart by the oblique faces M M for the purpose of seizing
with their edges the ends of the staple and completely pressing the same
against the insides of the cardboard box.
The whole substantially as described and illustrated and for the purposes
specified.
