13 Claims.
The present invention relates generally to a
binding mechanism, and more particularly to a
novel mechanism for spreading an elastic tubu
lar binder for the purpose of inserting a pack of
5 perforated sheets to be secured by the binder, to_
obtain a book of sheets or pages, of the type
shown and described in United States Letters
Patent No. 1,970,285, dated August 14, 1934,
_ granted to R. M. L. Douvry.

The binder comprises a continuous back por
tion having a number of ?ngers extending from
one longitudinal edge thereof, and made of a
(Cl. 11,-1)
into a longitudinal tubular form as shown, and
which has su?icient ?exibility to permit spread-'
ing' it open, and sufficient elasticity to cause it to
recurl when released. It has been found that a
certain type of cellulosic material'can be curled U!
into this shape when heated, and after cooling
retains that shape.
'
Referring now to the several views of the
spreading apparatus, asupporting base 4‘ sup
ports a working plate 5, which, for convenience of 10
manufacture is made in two parts, a front plate
6, and a rear plate ‘I, both of which are secured

into a socket 28 in the supporting frame 4. A
compression spring 29 is disposed on the exten

supported by a second bearing 30.
Meshing with the rack 23 are pinions 3|,
mounted on a' through shaft 32, which is carried
in bearings 33, 34 at each end respectively of
10 the supporting base 4. A crank 35 is ?xed to
one end of the shaft 32 and is rotated angularly
by an operating rod 36 jointed thereto. -
Normally, .the apparatus is in the position
shown in Figure 2, the row of hooks being near
15 and vin alignment with the row of pins. When
the operating rod is actuated, preferably by a
foot pedal (not shown), the pinions 3| are ro

pins 9.
An assembled book can be disassembled in a
similar manner. The book is ?rst pressed down
on the pins, which must, of course, be inserted
between the ?ngers as before, and between the
pack of sheets 38 and the back portion‘ 2. The
rod 31 is then inserted axially through the
binder, under the hooks l6, and then by actuat
ing the operating rod 36 as before, the ?ngers 10
are spread open, the ends of the ?ngers being
thereby withdrawn from the perforations. After
lifting the pack of sheets away from the hinder,
the operating rod 35 is released, allowing the
empty binder to recurl. The rod 3‘! is then with
drawn, and the binder can ~be lifted from the
pins.

The binder I ‘is laid on the working plate 1
with the back portion 2 held between the back
ing plate I 0 and the row of pins 9. The pins
are spaced so that they stand in spaces between
?ngers‘ 3 .of the'binder. i. ,The backing plate In
35 is set at such a distance from the pins 9 that it
will hold the back portion 2 against the pins 9.
With the rack 22 in the extreme left positioi
as shown, each of the hooks I6 is in a space
between ?ngers 3 of the binder l._ Certain of the
40 spaces between ?ngers 3 now are occupied by
pins 9 while other spaces between ?ngers are
occupied by hooks IS. The spacing of hooks and
pins may be such that every space between ?n-'
gers is occupied by either a hook 16 or a pin 9
45 but this is not essential, as the spacing can be
made such that there are some unoccupied spaces
between ?ngers 3.
