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
APPARATUS FOR BINDING BOOKS AND SIMILAR OBJECTS WITH METALLIC STAPLES,
a communication to me from abroad by Carl Louis Lasch, of Reudnitz, in the
kingdom of Saxony, Gentleman, to be as follows :—
This invention relates to small wire stitching machines or hand power machines
for binding books with wire staples.
The improvement consists in bending and clinching the staple to the same
shape as effected by large and expensive machines of the same kind, that is
to say in bending the staple at approximately right angles (E shaped, instead
of C shaped).
For this purpose I convert the saddle bed of a hand wire stitching machine into
a bearing serving to hold a bending apparatus adapted to move up and down in the
said saddle bed and carrying the guides serving to set the folds, which guides
consequently also move up and down.
This bending apparatus has inside two small pivoted plates, placed symmetrically
to the centre and pressing with their contiguous ends upon a fixed bearing placed
in the centre line of the machine.
The bending apparatus being pressed downward by the staple driver connected
with the band lover, the pivoted plates are placed horizontal and press the staplo
arms smoothly and neatly against the paper. For the purpose of moving the
bending apparatus upward, the machine is provided with two springs placed right
and left of the stand.
These springs possess such a strength, that the bending apparatus with the guides
is held so long above until the staple is driven into the material, after which the
springs are bent so much by the constant pressure of the hand lever acting from
the top, that the pivoted plates are placed horizontal.
For the purpose of filling the horizontal staple arm or feeder of the machine with
wire staples, a rapid removal of the upper part situated under the staple driver, and
consequently the removal of the hand lover from this upper part, is necessary.

page_text: For this purpose the hand lever is provided at the under side with a slot or a
hook open at the back, and in which the staple driver is held by means of a pin,
so that it cannot become spontaneously disengaged because the pivoted link, which
holds the fulcrum of the hand lever, is constantly drawn towards the rear by a
spring.
The machine works as follows:
The staples are pressed horizontally forward by a slide and a spring k situated at
the rear of the feeding arm.
Owing to the upward movement of the stamper or staple-driver by means of the
hand lever, a staple is allowed to enter a vertical slot below the stamper.
When the stamper is pressed downward, the staple is first forced through the
paper placed on the saddle bed.
When the hand lever is pressed further downward, the springs situated under
the bending apparatus are bent, the bending apparatus provided with the right and
left hand guides or platforms moves downward, and thereby places the pivoted
plates into a horizontal line, whereby the staples are bent in the manner described
above.

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
APPARATUS FOR BINDING BOOKS AND SIMILAR OBJECTS WITH METALLIC STAPLES, a
communication to me from abroad by Carl Louis Lasch, of Reudnitz-Leipzig, in
the kingdom of Saxony, and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
The little hand machine, previously constructed by my correspondent, for the
purpose of binding books or pamphlets by the insertion of wire staples or clamps
through the fold of the same, possesses the disadvantage, that by its use the sides
or shanks of the staple are bent only by driving them into a groove and
consequently obtain the shape s, indicated by the annexed drawing.
This imperfect clenching of the shanks is avoided by the improvement hereafter
described and illustrated by the drawing, which enables one to stitch by means of
this simple apparatus as correctly as by the larger and more expensive machines.
The staples are thereby bent into the shape 81, indicated by the drawings, which
is also the shape, attained by means of larger machines, furnished with complicated
clenching-apparatus.
In the drawings Fig. 1 is a side elevation with partial section, and Fig. 2 a front
elevation, with partial section, of an apparatus embodying the invention, while
Fig. 3 represents a detail.
The invention chiefly comprises a clenching apparatus, movable up and down in
the supporting saddle A, and on the side of which are situated the rules or knife
edges for fixing the fold, which consequently are likewise moving up and down.
This clenching apparatus a has inside two binged plates bb, which rest with their
free ends upon the fixed anvil c. When the clenching apparatus is pressed
downward by the staple driver e, connected with the hand lever d, the little
plates b b get into a horizontal position and press the staple shanks smoothly and
neatly against the paper.
The subsequent upward motion of the clenching apparatus is produced by two
springs ƒ ƒ, having such a strength, that at first the clenching apparatus with the
fixing rules m m, attached to it, is kept in its highest position, until the staple has
been driven in, and that subsequently the continued pressure of the hand-lever d
causes the springs to bend, in consequence of which the clenching apparatus moves
downward and the hinged plates or short levers bb get into the horizontal position,
indicated by Fig. 3.
To provide the hollow feeder or receptacle g with wire-staples, the upper or front
part / must be removed quickly, and consequently the hand-lever d be released
from this upper part. For this purpose a hook is formed on the lower side of the
hand lever d, in which the staple driver e is secured by means of a pin o. The lever
cannot detach itself, because the link i hinged to the beam g¹is always {pulled
hackward by the spring k

page_text: The stitching is done as follows: The staples are automatically pressed forward
by the slide-bar 1, under the influence of the spring k. The staple driver e is first
lifted out of the head piece h by means of the hand lever d, so as to allow a staple
to get into the feed channel. under the driver. By pressing down the driver, until
the stop pin p comes in contact with the head-piece k, the staple is driven through
the paper, laid on the clenching apparatus a. By farther pressing down the hand
lever, the motion of the driver is communicated to the head piece h and feeder g by
the pin n; the springs ff are bent, the clenching apparatus, together with the
fixing rules m, moves downward and thus brings the symmetrically hinged
plates b b in a horizontal position, whereby a correct clenching is obtained.
g is a beam hinged to the stand of the machine at q and carrying the staple-
feeder or receptacle g, which may be similar to that of other machines.
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
In apparatus for binding books or similar objects by inserting metallic staples
through their fold:
1) A clenching appliance movable up and down in the supporting saddle, the
said appliance comprising a pair of bending plates or levers 6 b, adapted to move up
and down with the fixing rules m, m and to rest on a stationary anvil c so as to
form a straight line, when in their highest position; and a pair of springs f, f,
adapted to produce the upward motion of the rules m m and levers b, b,
substantially as described.
2) The combination of a hand-lever d, having a hook adapted to detach the lever
from the staple driver, with a link i, and a spring k, the said link and spring being
adapted to keep the lever d in gear with the pin o of the driver, substantially as
described.
