‘The invention relates to book binding ma
chines, and more particularly to a machine for
inserting a spirally wound wire through theopen
ings of the leaves of ‘a book ‘as a ‘binding means
for ‘such leaves.
.In binding collated leaves by means of ‘a
51
spirally wound wire, the threading of the wire
through the series of openings in ‘the leaves has
‘been, prior to my invention, an ‘operation which
is su?icientlylslow to materially increase the cost
of ‘binding the books by this method. Books
bound ‘in ‘this manner are ordinarily ofa low priced
type, ‘such binding being commonly used in the
production of blank :books, :catalogs, scrap books,
etc. ‘ While bindings ‘of this type have proved to
be, ‘highly satisfactory in commercial use, the
cost of same is ‘unnecessarily high because of‘ a
limited output, due to Ethe time required to thread
the binder wire ‘through the openings in the
leaves.
‘
‘ ‘The main object of my present invention is to
provide a machine which, in its operation, will
engage and ‘rotate the ‘spirally wound wire at
highyspeed ‘without "likelihood of mutilating any
of the leaves of 'a book or deforming the ‘wire in
a :manner to interfere ‘with its ‘free turning while
, ‘being threaded through the openings in said
.
leaves.
‘
4‘ In :a machine embodying the invention, a roller
a: having a soft friction ‘suriaceyis rotated at ‘high
speed, this \roller‘being of ‘a length ‘to progressive
ly engage succeeding portions of a spiral of "the
necessary length ‘to‘form the binding. This roller
is rotated by a belt drive mechanism, which is
sufficiently ?exible to permit, notwithstanding a
continued operation of the source :of power oper
more, a yieldable surface upon the roller will
permit an automatic longitudinal adjustment of
said surface in relation ‘to the ‘various convolu
tions of ‘a wire and cause a displacement of the
wire in a manner to ensurea continued rotation 15
thereof, in the event of ‘the engagement of the
end ‘of the wire with a portion of the leaves
about an opening rtherethrough. If, for any
reason, ‘the vend of the wire should not clear the
walls of an opening, the ?exible driving member 20
operative upon the roller will yield, thus inter
rupting the turning of the roller or reducing its
speed in a manner to vary the speed of the
longitudinal feed of ‘the vwire, or even to arrest
this feed until theendof the wire is disengaged 25
from. the :leaves, or until a book may be removed
from the ‘machine .in an incomplete condition to
prevent the mutilation of the wire.
Embodied in the machine is ‘a .mechanism en

portions of the leaves are thus raised as the wire
progresses in its course through the openings I3.
To ‘prevent excessive vertical displacement of
the leaves due to the above action, I provide a
presser bar 2| having a ?attened surface engag
ing the leaves along the entire length thereof ad
jacent all of the opening I3. This presser bar is
carried by arms 22 adjustably attached to crank
arms 23 upon a rock shaft 24, the ‘opposite ends
of which are mounted in the standards I5. The
shaft 24 carries an actuating crank arm 25 which
is connected by means of a link 26 with a foot 70
treadle 21 acted upon by a spring 28.
The presser bar 2Iis engaged with the leaves

shaft 24 through theitreadle 21, the link 26 and
the crank arm 25.

The standards [5 are provided with vertical
dovetailed guides as shown more particularly in
Fig. 4, in which the heads l6 and the bearings
l1 arevertically adjustable. These heads per
mit vertical adjustment of the roller is to adapt
the machine for use with books of different thick
nesses, the angular relation of the arms 22‘ to
the cranks 23 and the bolts 29 permitting the set
ting of the presser bar 2| to adapt it to books of
is of greater diameter than the coil itself. The
speeds mentioned, however, are not critical, and
some slippage may occur between the surface 20
and the wire of the coil.
Those portions ‘of the collated leaves through
which‘the coiled wire is passed by hand are raised
slightly, by the lowermost portions of the coils,

from the shelf I I, as are the portions of the leaves
in the direction of movement of the wire, adja

to permit the end of the coil to pass freely be—
tween the lowermost leaf and the shelf during

ing 33 in said bearing blocks. A butter?y head or
other means 34 is‘ provided to facilitate the
roller [9. This raising of the collated leaves by 15
the wire progresses throughout the entire length
of each book as‘ the wire advances through the
10 different thicknesses.
.
The adjustment of the bearing blocks‘ is by
means of a lead screw 30 having a recessed por'
turning of said lead screw.
.
While the adjustment in the height of ‘the
roller in relation to the shelf II is primarily to
20 adapt the machine for use in binding books of
different thicknesses, the lead screws 30 may be
used to regulate the pressure exerted by the cover
or jacket 2|] against the coils of the spring.
The roller [9 is turned at high speed by means
of a pulley 35 carried by its shaft It, this pulley
being geared to the driving pulley 36 of an elec
tric motor 31 by a ?exible or elastic belt 38. The
use of this elastic belt permits the vertical ad
justment of the roller I9, and at the same time
will permit the stoppage of said roller without
interrupting the actuation of the motor 31, the
purpose of which will appear hereinafter.
The operation of a machine embodying the
invention is substantially as follows:—
In binding books by means of the machine
35
made in accordance with the invention, a spirally
wound binder wire [4 has one end thereof in
sorted. by hand for two or three turns through
openings l3 in the leaves I2, as indicated in Fig.
5. Collated leaves with the spiral wire partially
40 threaded in this manner are stacked upon the
shelf ll.
Such collated leaves are removed by
the operator from the stack, and after being
succeeding openings Hi.

' Assuming that the‘pitch of the coils of the
spiral binder wire is eight to the inch, and that
an eight inch book is being bound, the‘ run‘ of
the wire will be at the rate of two hundred inches
or more per minute, thus permitting twenty-five
eight inch books to be bound per minute. The
speed of rotation of the coil in excess of 1600
revolutions per minute, and the hand threading
of some of the coils through the openings 13 per
mits this speed of production to be maintained
and allows time for the feeding of the collated
leaves.
30
‘
With shorter books, the theoretical speed of
production would be greater, although in actual
practice, the time required for hand feeding of
the books places a limitation upon the output-of
the machine.

‘
The above figures are largely theoretical, actual
practice having demonstrated that as many as
?fteen thousand books can be bound during an
eight hour working‘ day. Of course, this ‘speed
requires highly skilled operators and does not 40
include the hand threading of the leaves.
As a
matter of practice, it requires three hand opera;
tors to keep two machine operators busy.

With a high speed of operation of the machine,
there is a tendency, because of the spiral trend 45
of the binder wire and the flexibility of this wire,

20 of the roller l9 to have slight movement along
collated leaves to ensure a proper subsequent
50 winding of the coil through the openings there
through. Substantially simultaneously with the
engagement of the coil with the jacket 20, the
treadle is released, thus permitting the presser
bar 2| to descend and hold the collated leaves I2
55 against upward movement except between the
bar and the edge of the shelf.
As the coil I4 is pressed against the jacket 20
of the roller [9, this jacket yields under the pres
sure of the feeding movement, the portions there
of engaging the few convolutions of the wire
threaded through the leaves forming an oblique
depression in said jacket, as to each portion there
of contacting with a coil. The yieldability or
compressibility of this surface 20 ensures a grip-‘
65 ping contact of the roller and the coil extending
throughout possibly 120° of the diameter of the
wire.
‘
‘
The roller l9, while threading a coil through
the openings in the collated leaves, is rotated,
70 about a ?xed axis, continuously at high speed.
In the machine shown in the drawing, this speed
is approximately 1600 revolutions per minute, so
that the turning movement imparted to the coil
will be in excess of this speed, since the roller ‘ t9
the wire, which will impart a re?ex movement 50
to the various coils and relieve the contact be
tween the end of the wire and the paper. Imme
diately that this occurs, the threading action
will be resumed.
55
In the completed product, the succeeding con
volutions of the spiral wire have a snug ?t with
the walls of the openings [3.
By locating the axis of the roller l9 above the
axis of the wire, as shown more particularly
in Fig. 3 of the drawing, and by turning the
roller l9 clockwise, there is always a downward
pressure upon the wire as to the portion thereof
engaged by the surface 20 and no- lifting of the
leaves except that resulting from the engagement
of the lower diameter of the coil with the shelf
II ‘which, because the diameter of the coils of
the wire is always greater than the height of the
collated leaves, will afford the necessary clear
ance beneath the edge of the leaves for the
passage of the wire. ‘ This raising of the leaves
is not great, but is sufficient to permit a smooth
running of the wire throughout the entire length
of the book. The lifting action is progressive
with the advancement of the wire.
if
75

2,136,’? 73
The presser bar 2| limits the extent of this
lifting action and restricts it to a portion of the
leaves adjacent the openings I3. It also pre
vents any separation of the leaves which might
interfere with the run of the coil.
By raising or lowering the heads [6 by means
of the lead screw 30, the machine may not only
be adjusted for use with‘ books of different thick
nesses, but a proper engaging relation between
10 the surface 2|] of the roller I9 and the coil may
be determined. With thicker books, coils of larg
er diameter are required and upward adjustment
of the roller I9 is necessary. With thinner books,
the reverse is true. No adjustment other than
15 that of the roller I9 is required, since this roller
itself serves as a stop to accurately position the
coil of each book in relation thereto.
When the roller H! has been set for use with
a desired thickness of collated leaves, its axis
20 remains ?xed in relation to the feed shelf, both
during the feeding of the collated leaves in rela
tion thereto and while threading the coil through
the openings in such leaves. This permits ac
curate, ‘rapid feeding of the collated leaves and
25 contributes materially toward a high output of
the machine.
The engagement of the roller with the coil
below the horizontal diameter of the roller en
sures that compressibility of the surface 20 neces
30 sary to secure the required frictional engagement
between the surface 20 and the wire of the coil.
Hence the operator need apply but little pressure
to the leaves in feeding them to said roller.
By using the ?exible belt 38, and in actual prac
35 tice this belt is in the form of an ordinary rubber
band, the rotary movement of the roller [9 will
vary according to the resistance encountered in
running the wire through the openings l3. This
resistance varies at different stages in the thread
40 ing of the wire by reason of the frictional engage
ment between the coils of the wire and the walls
of the openings I3, and the number of coils en
gaging such openings. Furthermore, if the end
of the wire should engage the walls of the open
45 ings, the speed of the roller will be momentarily
checked while the feedback action above referred
to occurs. The elastic belt yields when the speed
of the roller I9 is checked from any cause, thus
permitting the continuous operation of the motor
50 with a varying speed of rotation of the roller.
The time intervals amount to small fractions of
a second, since even with an eight inch book the
complete operation requires approximately only
two seconds.
With books of different thickness using wires of
different diameters and leaves having the open
ings l3 therethrough spaced at varying distances
from the edge of the book, the presser bar 2| may
be adjusted toward or from the openings and the
60 edge of the book, by releasing the lock nuts 29 and
allowing the presser bar to adjust itself to the
surface of the books by raising the bar until it
' occupies the proper position in relation to the
openings. In the form of the invention shown,
the treadle spring 28 is relied upon to develop the
desired holding action of the presser bar, although
other means may be used for this purpose.
It is not my intention to limit the invention to
the precise details of construction shown in the
accompanying drawing, it being apparent that
such may be varied without departing from the
