LOOSELEAF BINDER
Raymond S. Brown, Columbus, Ind.
Application -March 13, 1936, Serial No. 68,704
'13 Claims.
The present application relates to a loose leaf
binder, and more particularly to a binder :or
holder for a sheaf of loose vpapers, primarily in
tended -to;be used as a scratch pad.
A primary ‘objectof the invention?s to :provide
a~device of ‘the type indicated ‘which can be used
to bind unperforated sheets of standard size; so
that its use will not ‘only be Bless expensive than
5
the use of ‘holders of the type ‘which require
10 perforated paper, but will also be less trouble
some; in that the paper 'may 'merely be slipped
into place in the holder, and then ‘clamped in
position.
the description proceeds.
‘

apply such advertising legend to the separate plate
than to cross bar 16.
The bar 16 is provided, at its edge adjacent to V
the pivot axis I3, with a down turned lip I845
which is adapted to be pressed in clampinglen
gagement with the sheaf H of paper.
The .pro
vision of the lip I8, not only makes for more
satisfactory gripping of the paper, but improves
the capaoity'of the clamping means for provid- ‘11.0
ing for smooth tearing of the sheets along the
line of engagement of the lip I78. 7
Immediately adjacent the end of the base I0
Further objects of the invention will ‘appear'as

(Cl. 129—35)
nearest the cross bar I6, there is mounted an
‘To the accomplishment of ‘the above and ‘re
lated objects, my invention maybe embodied in
upstanding screw I9 which is suitably secured..15
to the base and is held against any movement
with respect thereto. A nut .20 is vthreadedly
the forms illustrated inthe accompanyingdraw
mounted onsaid screw I9,-and-is adapted'to be
ing, attention being called to ‘the fact, however,
that "the drawing is illustrative ‘only, and ‘that
change may be 'made in the speci?c construc
engaged in a notch 2| formed in the adjacent
edge of the cross bar l6. As is clearly illustrated .20
in Fig. 2, the lips 22 and .23 of said notch 2| '
tions illustrated and described, vso ‘long "as the
scope "of vthe appended ‘claims vis ~not violated.
Fig.' 1"is a'perspective View of ‘a binder con
are bent ‘downwardly at approximately the axes
or points 24, 24; and, as is indicated in Fig.4,
said lips are .further bent-downwardly about -an
structed :in accordance with "the present inven
tion, with which is associated a sheaf of papers;
vaxis substantially perpendicular to‘the axes-'24, 24, :25
Fig. '2 is an enlarged fragmentary "end eleva
tion thereof;
‘Fig. 3 'is a plan view thereof ‘with the 'papers
removed;
‘
‘Fig. '4 'is a fragmentary longitudinal section
ftaken‘substantially'upon line 4—-4 of Fig. 3 and
looking in the direction of the arrows; .and
Fig. 5 is 'a fragmentary "end ‘elevation similar
to Fig. 2 "but illustrating‘a ‘modi?ed ‘form 'of‘the
invention.
Referring more particularly'to the drawing,‘it
will be seen that I have illustrated a'base I I] of
suitable dimensions ‘for supporting ‘a sheaf ‘of
4.0 loose papers ‘I I.
Upwardly projecting from ‘its
opposite edges are ears or ?anges I2‘which serve
as guides ‘in inserting a sheaf of papers, and
which further provide supports‘to‘which levers
I4 and "I5 maybe pivotally secured'by means of
hollow rivets I3, or the like. The ‘free ends of
the levers “and ‘I5 areconnected by a crossbar
‘I6 which, in the illustratedembodiment of the
invention, is integral with said levers.
Preferably, ‘the ‘bar 46 -is of su?‘icient size, "in
U1) the direction of ‘the length of the base I0, to
hear an ‘advertising legend; and, in the illus
trated embodiment of the invention, I have pro
vided'a separate plate I‘! secured to the upper
surface of the cross bar IS in any suitable man
‘ her, with the idea that it-will beless expensive,
as at 25.
'
Adjacentits bottom end, the nut 20 is formed
with'a circumferential groove 26 bounded at its
upper edge by a substantially ?atsurface'or wall
21, and at its lower edge by a chamfered wall or 30
?ange 28. The ‘lips 22 and 23 are engaged in
said groove \26; ‘and it will be seen, therefore,
that ‘rotation of the nut in one direction will
‘positively move the bar l6 toward the base ‘Ill,
while rotation of the nut in the opposite direction;.35 '
will positively move saidrbaraway from said base.
The manner in which the lips Hand 23 are
bent downwardly about the axes 24 and .25 is
such that, as the bar 16 moves about its pivotal
axis I3, in a counter-clockwisedirection as viewedAO
in Fig. 4, thus being drawn toward the left 'as
viewedgin Fig. 4, the portions of the ‘lips which
engage with the walls of the groove 26 remain
substantially perpendicular ‘to vthe axis vof ‘the
screw I9.
'
That surface of the screw ’ I9 which faces away
from the adjacent end of the'base IO‘is ?attened,
as at 29. Thus the screw may be used as an abut
ment for determining the degree of =insertion'of _
the paper into the holder, and yet the individual
sheets do not tend to 'hang'up on the threads
of the screw, since the ‘threads are eliminated
onithat‘portion of the screw which is engaged
" by the paper.

3. A loose-leaf binder comprising a base hav
ing a ?at portion for supporting a sheaf of pa-.
pers, a pair of leverslpivotally mounted upon
aligned axes'on opposite sides, of ‘the ?at por
tion of said base and intermediate the ends there
Preferably that end of the base remote "from
the screw I9 is formed with a thumb notch 30.
It will be seen that I have provided a holder
' comprising a base, a bar adapted to cooperate
.with said base to clamp a sheaf of paper on
said base, said bar'being mounted upon a .pair ' of to lie beyond the edges of said papers, at barv
joiningrthe free ends of said levers, and means
of levers'of the'second class, the load being the
sheaf of leaves 'to be compressed, the fulcrums
for said levers lying in, or adjacent to, the pro
10 jected side area of the pad. The levers lie‘close
providing a connection between’said bar and
said‘ base for causing said bar to exert a'retain
10
ingpressure upon said papers.
4.' A loose-leaf binder comprising a base, a‘pair' 1
alongside the padof ‘paper, thereby aiding in
aligning the individual leaves of the sheaf; and,
the 'fulcrums being positioned as they are, the
whole unit is quite compact. The means for
15 forcing the cross bar into clamping relation with
the sheaf of; paper is positioned :outside the
'7 boundaries of the sheaf, which makes it unneces _
sary to use holes or notches in the leaves, so
that re?lling of the pad is very inexpensive. .
20
_ vWhile the above described organization is use
’ful primarily as amemorandum pad, it could be
" used in: an enlarged form for l?lingrcorrespond
ence and other papers. ‘Preferably, however, a
different form of holding means for the cross bar
would be usedain, 7'such1a‘ho1der. In Fig. ,5, I have
illustrated a base 3!, adapted to supporta sheaf
