Improvements in Memorandum Books.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
In the accompanying drawings:
:-
Figure 1, is a plan view of my improved memorandum book, as prepared for the
application thereto of the binder.
Figure 2, shows the book as in figure 1, but with the binder in the first stage of
its application to the book; a portion of the book, being, in this and the three next
figures, broken away.
Figure 3, is like figure 2, except that it shows the binder at an advanced stage of
its application.
Figure 4, is like figure 3, with the exception of the binder, which is advanced a
stage in its application.
Figure 5, shows the book, with the binder in position thereon for use.
Figure 6, is an edge elevation of figure 5, showing one lid partly open.
Figures 7, and 8, show modifications in the preparation of the book for the binder ;
which latter is omitted in figure 7, and is applied in figure 8.
Figure 9, shows my memorandum book as opened, and with the index in position
for use.
Figures 10 and 11, show the book with the central slot omitted.
The objects of my invention are to provide a continuous or perpetual pocket
memorandum book; and to supply the same with leaves of various colors, shades,
and hues, and having an index with bands or spaces correspondingly colored, to
enable the user, the more readily to turn to the subject matter sought, by aid of the
index. The memorandum book being indented at the edges (and preferably also at the
center) near one end of the lids and leaves, and then secured together by an elastic
binder all as will by aid of the drawings be hereinafter described and claimed.
In said drawings, a, a, represent the lids of my pocket memorandum books, which
may be formed of ivory, celluloid, metal, bard rubber, or hard finished cardboard,
or any other suitable material, as fancy or economy may prompt or dictate. Said
lids are severed, as at c, figures 7, 8, and 10, and as also shown in figures 6, and 11;
the two parts of each lid being united and held in proper relation by a flexible
band or hinge b, preferably of cloth, which may be cemented to the cover, or
otherwise secured thereto. At a point about midway between said separating
line c, and the adjacent end of the book, I form in each edge through both covers
and leaves, a recess or notch d, and preferably a close slot e, in line with and inter-
mediate between said recesses d. The gum elastic binder, is shown at f, and is the
well known endless band. The method of applying this binder, when the close slote,
is employed, is clearly shown in figures 2, to 5; as in figure 2, one end or "bight
of the binder has been passed through slot c, and is there held by the thumb of the
hand that holds the book; while the other hand has grasped the opposite bight of
the binder and has carried it to and seated it in the notch at one edge of the book,
and is extending the binder to the opposite notch, in which it will be seated, as is
clearly shown in figure 3; when the bight that is shown in figures 2 and 3, as held
by the thumb, against the cover, is carried first to one of said slots d, as in figure 4,
and then to the other, as shown in figure 5, where the binder is in position for use.
If the open slot g, is substituted for the close slot e, then binder f, may be passed

page_text: over the end of the book and directly into the open central slot; the binder when in
final position, occupying the same position whether slot e, or g, be employed. Slots d,
may be employed without the central slot, as in figure 10, but it
employ the latter.
preferable to
My improved, coinciding index, is shown in figure 9, where h, h, etc.
represent bands of divers colors such as white, yellow, orange, pink, green,
and other shades, colors, or tints while the leaves i, of the book, will be
the
made up of colors, shades, and tints corresponding to those in the index;
use and experience may
number of leaves in each shade or color being such as
show to be requisite, according to the purpose to which each color is devoted.
When any shade or color has been entirely utilized it is removed, and other
leaves of the same color are placed in the book in lieu of those so utilized;
and if the book should be all of one kind of paper, white for instance, then when
all has been utilized, it is removed from the covers and new paper is placed therein,
When exhausted paper is removed from the book, which it is desired to
preserve, for reference or other purposes, it may be placed between lids, such as
shown in figure 10,-without the central slot-and be so secured by a band f, of
a length just sufficient to pass directly around the book, as shown in both said,
figure 10, and in figure 11, which is an edge view of figure 10. It will be obvious
that when my coinciding index is employed, upon consultation thereof, and finding
the required heading thereon, and noting the color or shade of the band or stripe on
which such heading appears, it will be only necessary to then refer to those leaves
having a color or shade coincident with said stripe of the index; thereby avoiding
a much more extended search in the body of the book, as has heretofore been
necessary.
for use.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed as communicated to me
by my foreign correspondent I declare that what I claim is
1. In combination with the leaves i, having the edge notches d, the lids a, a,
having corresponding notches and flexible hinge b, substantially as specified.
2. The combination in a memorandum book of an index duly spaced and provided
with representative colors, and leaves, in the body of the book, duly arranged in
their respective colors corresponding to the colors in said index, substantially as
specified.
3. As an improvement in memorandum books the covers and leaves formed with
the notches or grooves across the edges thereof, and the intermediate slot extending
through the book, substantially as specified.
4. In combination with the book formed with the edge notches or grooves and
intermediate slot formed therein; the elastic binder arranged in said slot and recesses,
substantially as specified.
