IMPROVEMENTS
IN
HERBERT JOHN HADDAN, of Kensington, Middlesex,
MACHINERY FOR STITCHING OR BINDING BOOKS BY MEANS OF WIRE STAPLES,
communicated to me from abroad by August Brehmer, of Leipzig, in the kingdom
of Saxony.
The machine shown in the accompanying drawings has been constructed for the
purpose of sewing books, pamphlets, catalogues etc. by wire; it will stitch books
of one section through the fold, or books of several sections through the side after
the manner of stabbed work.
Fig I is a perspective general view of the machine; Figs II, III & IV show the
different forms of tables upon which the books are laid for stitching. Figs V, VI,
VII and VIII show the construction of the parts which form and insert the wire
staples. Figs 1X & X represent the appliances for starting and stopping the
machine.
The machine is driven by a belt running upon the pulley 1 which turns in the
direction of the arrow marked thereon.
It is mounted upon the shaft 2 which passes through the frame of the machine
and carries at its other end the gears and cams as shown in the drawings.
The wire taken from a reel is fed into the machine by a pair of rollers 3, 3,
which are geared together.
The lower roller, the shaft of which carries a ratchet wheel 5, is set in motion
by the pawl 6, crank 7, rod 8, crank 9, and gear 10, from the bevel gear 11, which
is fixed upon the shaft 2. The upper feed roller 3 is mounted upon a small shaft 12
which can be adjusted by the screws 13 to give the desired distance between the
two rollers, for thick or thin wire.
The rollers push the wire through a guide channel 14 forward through the
Prins G71

page_text: cutter holder 15 where the cutters 16 & 17 (Fig V) cut the wire to the length
desired. The cutter 17 is fastened by the screw 18 around which it can be set at
various angles. The cutter 10 against which the wire is being pressed while being
cut may also be turned around in the plate 19 which is secured to the cutter-
holder 15 by a screw 20.-The turning of the knives serves to utilize every point
of the cutting edges before a renewal of the cutters is required. After being cut
off, the piece of wire remaining in the wirehead 21 will be formed into a staple.
Fig V shows this position of the machine; but to show the operation more clearly,
the cover 22 of the wire head 21 has been left out in the drawing.
The cutter 17 which has just cut off the wire is now starting on its backward
motion; the staple driver 23 and the two fingers 24 of the mandrel 25, around
which the staple is being bent, have meanwhile approached one-another and hold
the piece of wire tightly pinched, while the bender 26 with its two shanks 27
sliding in the two grooves 28 turns the wire ends in a right angle around the
fingers 24, and thus forms the staple. When this is done, the mandrel 20 returns
into the position shown in Fig VI by dotted lines; the driver 23 will now push
the staple upward and will drive the legs of the staple through the book which has
been placed upon the wire head 21. The spring 29 serves to make the pressure of
the driver an elastic one. The two shanks 27 of the bender 26 have in the mean-
time proceeded upward to the top of the wire head 21, and fill the grooves 28
completely, so that the staple may be well guided in the slot 30.
The mandrel 25 receives its motion from a crank 31 (Fig I), to which is fastened
a roller near 32 turning in a cam groove 33, which gives the motion up or down
when required. The driver 23 receives its motion upward from a roller 34 turning
upon the outer surface of a cam 35; its downward motion is effected by the
bender 26, which again receives its motion from a cam-groove at the back face of
the same cam 35. The crank 31 and the bender 26 are guided at their lower ends
upon the shaft 2.
The cam 36 serves to move the holder 37 with the cutter 17 upwards, while the
holder 37 falls back by its own weight and by the spring 38.
After having been driven through the book the projecting legs of the wire
staples will be clenched by a clenching apparatus 39 which is of similar
construction as that described in the Patent No 3497 dated September 17, 1877.
The clencher is operated by the parts 40, 41, 42 and 43 from the cam 44, which is
fastened to the bevel gear 10; the return motion is effected by the spring 45. The
clencher 39 is fastened to the sliding part 46 and is held by it tightly against the
surface of the book, while the staple is being driven and clenched. The sliding
part 46 receives its motion from a cam 50 through intermediate parts 47, 48 & 49.
The balance lever 48 has its fulcrum at the bolt 47; The return motion is
effected by a spring 51.
Figs IX. and X show the stopping and starting gear, In the position shown the
machine is at rest, while the pulley 1 to which is fastened a ratchet wheel 52, will
turn freely upon the main shaft 2 and in the direction indicated by an arrow. To
start the machine the foot of the operator. has to press upon the lever 53, whereby
the rod 54 will be pulled back in the direction marked by an arrow, and the
spring 55 will cause a pawl 56 to drop into the teeth of the ratchet wheel 52.
Pawl 56 swivels on a bolt 57 which is fastened on cain 50, which latter together
with the brake pulley 58 is keyed on to the shaft 2. The brake is composed of
the pulley 58, strap 59 and weight 60 and will prevent any backward motion of
the shaft 2. If the operator raises his foot, the counterweight 61 of the lever 53
will place the rod 54 back in its position of rest, the pawl 56, however, will
remain in the ratchet wheel until the back of the pawl 56 will slide under
the rod 54.
The projection 74 of the cam 50 which finally touches the rol 54 stops the
motion positively, and causes the machine always to stop in the same position.
This position is that shown in Fig I where the clencher 39 is in its upper position
and makes room for a book to be placed upon the wire head 21.

page_text: A A shaped table Fig. III placed upon the wire head serves to hold the paper
in proper position for driving the staples from inward to outward through the fold,
while a V shaped table Fig II serves to drive the staples from outward to inward
through the fold. In order to be able to arrive at a fast speed in feeding the
machine, the frame has its arm 62 bent to the side so that books fed through the
V shaped table need not be taken back to the front, but may slide backward away
from the table and drop down behind freely without being hindered by the frame.
A flat table Fig, IV bearing a guide for the books serves to drive the wire through
books of several sections from the side. The said tables are fastened by pins 63
in an opening 64 of the frame.
For the purpose of adjusting the space between clencher 39 and wirehead 21 for
different thicknesses of the books, a screw 65 with lock nut 66 is attached to the
lever 48. An index 67 shows readily the position for any thickness to be stitched.
The index 68 of the crank 9 attached to the gear 10 serves to determine the length
of wire required for the respective thickness of the book. The cutterholders 15
and 37 are also adjusted correspondingly by a screw 69, by which they can be set
more or less closely to the wire head 21.
The projection 70 at the front of the frame serves to hold a cover for the
protection of the cams. The free part of the pin 71, a screw 72 and hook 73
serve to fasten a cover for protecting the bevel gears 10 and 11.
.
Having thus described the invention, I wish it to be understood that I claim :
1.) In wire stitching machines the arrangement of the wire head and of the
clencher, in such a manner that wire staples may be inserted either from the
inside or from the outside through the fold of a book of one section, and
furthermore also from the side through a book of several sections, substantially
as described.
2.) In wire stitching machines the arrangement of the frame of the machine with
an arm bent to the side in such a manner that books of one section which have
been stitched through the fold from the outside inward may slide backward out
of the way of the next book to be sewn and need not be taken back to the
front of the table after being stitched, substantially as described.
3 In wire stitching machines the arrangement of the staple inserting apparatus
below the book and of the clencher above the book, substantially as described.
4. The apparatus for starting and stopping the machine as described.
5 The construction of the wire head in combination with a bender carrying two
shanks which are guided in grooves of the wire head, substantially as
described.
6. The combination of the wire head with the cutter holder which may be fastened
at any desired distance from each other, substantially as described.
7. The combination of the clencher 39, rod 40, lever 41, rod 42 and 43 and cam 44,
substantially as described.
8. The combination of the sliding part 46, lever 48, rod 49 and cam 50, substantially
as described.
9 The combination of the shaft 2, bevel gears 10 & 11, crank 9 and rollers 3 for
the purpose herein set forth.
10. The combination of the adjustable cutter holder, adjustable crank 9 & adjustable.
lever 48 for the purpose specified.
In witness whereof I; the said Herbert John Haddan, have hereunto set my
hand and seal, this third day of July A.D. 1883
