7 Claims.
This invention relates to loose leaf binders par
ticularly adapted for use in connection with ma
chine posting. In machine posting devices of the
front feed type it is very desirable to use sheets
5 having an unbroken top edge. This invention is
particularly concerned with means for retaining

are closed at their ends by means of end caps
I 3 of felt, über, or any other material adapted to
prevent the binder from marring any finished
sheets of this type in a binder in such a manner
that the sheets may be handled very rapidly dur
surface on which it may be handled. The back
members 2 and 3 are connected by a pair of
posts Id each of which consists oi a tubular sec
ing the posting operations.

It is an object cf this invention to provide a
as shown at i6, and a second tubular section I1
sheet retaining post that may be readily inserted
into a loose leaf binder to retain the sheets there
in and may be readily removed so as not to im

and adapted to telescope into the section I5. A
coiled spring i9 is contained within the telescopic
pede the rapid removal and replacement of the
post I4, and normally tends to expand to separate
15 sheets during the posting operations. It is a iur
ther ob-ject of this invention to provide simple
the back members 2 and 3.

The back members 2 and 3 are also connected
and eiîlcient means in the binder to securely re

rigidly secured to the plate member 3', as shown
at 22, and a solid section 23 secured to the plate 20
EL O , this invention will become apparent upon reading
the following description taken in conjunction
with the accompanying drawing, in which
Figure 1 is a cross sectional View taken sub
stantially on the line ï-I of Figure 2 through
25 the back of a binder embodying this invention;
Figure 2 is a fragmentary top plan View of
the binder with parts broken away to facilitate
illustration of the structure;
Figure 3 is a fragmentary cross sectional View
showing the means for removing the sheet retain
ing post;
Figure 4 is a detail perspective view of the sheet
retaining post; and
Figure 5 is a fragmentary perspective View of
35 the means for holding the she-et retaining post in
the binder.
_
In the drawing, the reference numerals 2 and
3 indicate a pair of clamping or back members
which are movable transversely relative to each
40 other.
The back members 2 and 3 each are pro
«vided with a plate member, 2’ and 3’ respectively,
which may be integral therewith, and which ex
tend at an angle to the back members. Cover
members 4 are hinged to the plate members 2’,
45 3', as indicated at 5. The ends of the back mem
v ber 2 are bent over, as indicated at 6, to form
guide channels in which the ends of the back
member 3 are moved. Interengaging tongues 'I
and 8 on the bent over portion 6 and the back
50 member 3, respectively, prevent separation of the
'

tubular compartment l2, The compartments I0
back members.
A channel shaped member 9 is rigidly secured
to the plate member 3’ to form a tubular com
partment I0. A channel shaped member Il is
55 rigidly secured to the plate member 2’ to form a
Each
member 2’ by means of a screw 2d and adapted to
telescope into the tubular section 2|. Each sec
tion 23 is provided near its unsecured end with
a conical portion 25 providing a space 26 in
which a plurality of gravity operated balls 21 is u
contained. The space 26 is closed at one end by
the body portion of the section 23 and at the
other end by a iiange 28 ñtting snugly in the
section 2l. The unsecured end of the section 2|
is provided with an inturned ñange 29 adapted to
engage the flange 28 to prevent separation of the
sections 2l and 23. When the binder is in the
position of Figure l, any attempt to move the
back members apart will wedge the balls 2l into
the small end of the space 26 and thereby prevent
such movement. When the binder is reversed the
balls 21 roll to the large end ci the space 26 and
the back members 2 and 3 may be moved apart
until the tongues 'I and 8 interengage.
l
The posts I4 and 20 are arranged adjacent the
ends of the binder, as indicated in Figure 2, so
as to permit the insertion of sheets 30 therebe
tween. The posts HI and 2li form a guide means
for aligning the sheets 3@ as they are inserted
in the binder. The sheets 3G are provided with
one or more apertures 3i through which sheet
retaining posts 32 may be inserted.
Each sheet retaining post 32 consists of a solid
section 33 adapted to telescope into a tubular
section 34. A coiled spring 35 positioned within
the tubular section exerts a constant force tend
ing to move the sections 33 and 3B out of tele
scoping relationship. A flange 36 rigidly secured
to the section 33 and a restricted outlet S'I on
the section 34 interengage to prevent complete 55

separation of the sections of the sheet retaining
post 32. The section 36% is provided with an en
larged head 38 and has a threaded aperture 3s
therein. A key ¿il having a threaded end lil is
adapted to be screwed into the aperture Se to
rotate the section 34 and to press it inwardly
against the action of the spring 35. The sec
tion 34 is also provided with a pin ¿l2 having a
pair of laterally projecting ends adjacent the
10 headed end 38.
The plate member 2’ and the channel shaped
member
Il are apertured in registration with
each other, as indicated at 43 and 4e, respectively,
to allow insertion of the sheet retaining posts
15 32. rlTne apertures ¿i3 are just large enough to
permit insertion of the tubular portions Se, but
the apertures ¿4i are large enough to receive the
headed ends 38 oi the posts. The plate member
3’ is apertured and embossed, as indicated at 45,
but the
20 to receive the tip end of the section
aperture is not large enough to allow the section
33 to pass therethrough.
The plate member 2’ has secured thereto a
plurality of members 46 each of which is aper
25 tured, as indicated at lil, in registration with the
apertures d3. The member @t is embossed to
provide a circular iiange QS surrounding the
aperture lll. The flange Q8 provides a space lig
between the plates 2’ and #it adjacent the aper
30 tures 43 and ill. The space #i9 is large enough
to receive the pro-jecting ends of pin 152. The
flange 48 is provided with a pair ci recesses 5S
through which the pin ¿i2 may be inserted into
the space ¿9.
After the pin G2 has passed
through the recesses 5d ak slight rotation of the
section 34 will bring the pin il?. under the flange
48 whereby the sheet retaining post may be heid
in position.
The ñange ¿i8 is provided with a pair of em
40 bossments 5i. When the section 3@ is rotated a
suñicient distance to bring the pin ¿i2 into align
ment with the embossments 5l, the spring 35
urges the pin d2 into the embossments. The em
bossments are deep enough so that the key @E
45 may be easily unscrewed from the aperture 32
without moving the pin 42 out of the emboss
ments. When it is desired to remove the posts
32 from the binder the key li@ is screwed into
the: aperture 39 all the
and then continued
50 rotation in the same direction will force the pin
out of the embossments 5i and into alignment
with the recesses 553 at which time the spring
35 will force the post 32 out of its secured posi
tion.
Although I have shown a binder equipped with
55
two sheet retaining posts it will be obvious that
the number may be varied in accordance with
the size of the sheets and the particular desires
of' the user. Inasmuch as many other detaiis
60 may be modiiied or changed without departing
from the spirit or scope of my invention it will
be understood that the description thereof is in
tended to be illustrative, rather than restrictive.
Accordingly, I do not desire to be restricted to
the exact construction described, except as lim
ited by the appended claims.
I claim:
