edges of the leaves is conveniently formed by a
continuous strip 24 of fabric folded into a num
ber of pleats 25E, 25h, 25C, 25d respectively receiv
ing the edges of the individual leaves, and each
5 glued to an upper marginal side of its corre
sponding leaf so as collectively to form a stepped
accordion binding which will permit a limited
rearward spacing movement of any overlying card
from the margin of the one below it when the
stack is opened as shown in Fig. 4, this spacing
movement being greatest in the case of the cover
23 and the next leaf 22a It is not essential that
the strip 24 shall be continuous in the portions
thereof which are glued to the leaves.
15
The rear or heel margin of the cover leaf 23
is anchored to the base I0 by a restraining strip
26 of fabric hingedly attached to said margin be
tween the free and heel edg'es of the leaf‘so as to
unfold away from the leaf like the side of an ac
cordion pleat as seen in Fig. 4, this anchoring
member being either a continuation of the strip
24 or a separate strip. Being hinged at each end,
the strip 26 constitutes a double hinge binding,
and each inter-leaf portion of the strip 24 is
25 similarly connected with the underlying leaf and
acts therefor in a like manner.
'
In the operation of this form of my invention,
assuming the stack is to be opened between the
lowermost card 2| or facing of the table and the
30 `one above it, so as to expose the information on
said facing card or permit writing thereon, the
operator presses his finger on the corner of said
card as indicated in Figs. 1 and 4, thereby de
pressing the forward 'end of the rocker platen
5 II and elevating its rear end. During the first
part of this movement, the action of the rear
corner edge 21 of the table I2, or the facing card
2l superposed thereon, pushes upwardly on the
overlying'stack through the lower leaf 22“, and
40 since the rear end is restrained-by the anchor
ing strip 26, the stack is caused to turn toward
a vertical position around said corner edge 21
until the strip 26À has straightened out in line
with the cover 23.
A continuation of the tilt
45 ing movement then causes the st-rip 26 to exert
a relative rearward and downward pull on the
lower edge of- said coverr23 and therethrough
upon the lower edges of the underlying leaves 22“,
22b and 22a, further moving said cover and leaves
angularly to a more open position and spacing
stack may be closed by directly handling the
open portion like an open book. It will be evi
dent that the stack may, in like manner, be
opened between any other pair of the cards or
leaves 22a, 22h, 22C, or the cover 23 alone may
be opened, by pressing at the appropriate place
on the indexed forward edge and holding down
the lower leaf of the pair, as well as those be
low it.
If it is not desired to arrest the stack in an
intermediate open position as indicated in full
lines in Fig. 4, the back stop I8 may be omitted.
When such a -stop is present, it is preferred to
have it automatically retractable as by mount
ing it on the rocking platen II, but that is not
broadly essential and said stop may be mounted
in other ways.
It could also be differently at
tached to the rocking platen.
In the modification illustrated in Fig. 5, where
in, as in >the succeeding views, the thickness of 20
parts excepting the base, >is indicated by solid
lines, a certain portion of the card stack consti
tuting a filler is made removable vand detachably
connected with the table I2 and cover 23 re
spectively by a flap 28 attached by its rear mar- `
gin to the under side of the lower leaf 22A and
extending forwardly under the table through the
aperture I6, and by another flap 29 flexibly con
nected with the rear edge of the upper leaf 22c
and adapted to be slipped into a sheath or pocket
30 on the under side of the cover 23, when said
cover is opened out rearwardly to bring said pock
et on top.
In the modification illustrated in Fig. 6, the
structure is the same as in Figs. 1 to 4 except
for the omission of leaves between the table I2
and the cover 23 and omission of the bindings
for said leaves. In this case a flexible binding
or hinge member 24“, such as a fabric strip, di
rectly connects the rear margin of cover 23 with A
that of the table I2, and said cover is actuated
by the rear corner edge 21 of the table to swing
said cover, whose rear edge is restrained by the
anchoring member 26, into an open position when
the rear end of the rocking platen II is raised
by depression of its forward end, as before. In
or separating them at their lower edges as seen
this case the upper portion of the platen is a
shallow receptacle having the table I2 as its floor
and-the cover 23 as its lid, adapted to receive a
writing pad or other contents, and capable of ‘à
variation in shape as desired.
in Fig. 4. This movement is arrested by the
cover 23 coming against the stop edge I8, at
In the further modification shown in Fig. '7,
the rocking platen is replaced by a stiff plate
_ which time said cover is in an upright position

and the adjacent leaves are leaning against it.
A removal of finger pressure upon the forward
edge of the device will then allow the rocking
platen to fall to a horizontal position and the
stack to close by gravity.
By applying the opening pressure forcefully
and quickly removing it, the stack may be caused
to flop over backwardly to a prone or substan
ously described, said plate being fastened by a
flexible hinge strip 32 upon the upper surface
of a horizontally movable member or slide 33,
upon whose forward corner edge 34 the plate 3l
and superposed leaves are fulcrumed for rock
ing motion. The extended rear edge of the cover
sheet 23, shown in open position by a broken
line in this view, coacts with a stiff strip 36
which is mounted in a. vertical plane on the rear
edge of the slide 33 and flexibly connected there
with at its lower edge, said strip acting as a stop
gate which is rigid in one direction, causing the
tially horizontal position with the platen in nor
mal position as indicated in broken lines in Fig.
