Improvements in Manifold Memorandum Books.
I, WALTER WINFIELD O'HARA, of Arlington, in the County of Middlesex,
and State of Massachusetts, United States of America, Salesman, do hereby declare
the nature of my invention for IMPROVEMENTS IN MANIFOLD MEMORANDUM
BOOKS, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :--
This invention relates to the class of memorandum books in which a carbon shoet
is secured to the book in such a manner as to allow said sheet to be introduced
between the leaf upon which the memorandum is to be written and the subjacent
leaf and thus produce on the latter a fac-simile of the memorandum written on the
top leaf.
The object of my present invention is to provide a manifold memorandum book
which shall allow the duplicate or copy of the memorandum to remain in the book
without necessitating handling the carbon-sheet.
And to that end the invention consists essentially in the combination, with the
cover and block of memorandum leaves fastened theroto, of a carbon-sheet holder
sustained movable to and from said block as hereinafter more fully described and
specifically set forth in the claims.
The invention is fully illustrated in the annexed drawing in which
Figures 1, 2 and 3 are plan views of memorandum books embodying my
invention,
Figures 4, 5 and 6 are perspective views illustrating the method of using said
books,
Figs. 7, 8 and 9 show said books in a closed condition, and
Figures 10 and 11 are perspective views of a modification of the memorandum
book and showing the saine in two different conditions which it assumes in the
manipulation thereof.
Similar letters of reference indicate corresponding parts.
A represents the cover of the book, ce c¹ the memorandum leaves which are
bound in block-form and secured at the bound end to a clamp C fastened to the
cover A. either at the center or at one end thereof according to the form of the
memorandum leaves and the manipulation required in the use of the book.
When the memorandum leaves are of the same or nearly the same length as the
cover and each of said leaves is folded separatoly upon itself the clamp C is fastened
across the center of the length of the cover as shown in Figures 1, 4, 7, 3, 6 and 9
of the drawings.
When the aforesaid leaves are all folded jointly the clamp C is attached to
the upper end of the cover A as shown in Figs. 2, 6 and 8 of the drawing, and
when the memorandum leaves extend only half the length of the cover, the clamp C
is also fastened to the upper end of the cover, as represented in Figs. 10 and 11 of
the drawing.
6 denotes the carbon sheet which is attached at one end to a clasp a which is
connected to the cover by an elastic support which sustain said clamp across the
top of the free portion of the block of memorandum leaves and movably to and from
the same. To facilitate the manipulation of the book so as to retain the copies
thoroin without handling the carbon shoot as hereinafter described, I employ-for
the support of the clasp a a single bar d which extends along one side of the block
of leaves and is secured at one end to the cover at or near the clamp C to which the
block of memorandum leaves is fastened. The clasp a is attached at one end to
the free end of the bar d.

page_text: The manipulation of the several modified forms of books shown in the drawings
is as follows:
In using the book shown in Figs. 1, 4 and 7 of the drawing the upper and free end
of the uppermost individually folded lenf c is to be lifted and carried down to allow
the carbon abeet b to be placed between the two sections of the lenf o which is
effected without handling the carbon sheet by the operator taking hold of either the
bardor end of the clasp a adjacent to said bar.
After the carbon sheet has been thus placed the fly or previously raised section
of the memorandum sheet is placed upon the carbon sheet which has tho carbon face
on the underside.
The memorandum being then written by a pencil upon the overlying section of
the leaf causes the carbon sheet to produce an exact copy of said memoraudum
on the underlying section of the memorandum loaf. Then the top section of
the memorandum leaf is to be again carried down by one hand, and the
memorandum leaf thus distended is to be drawn laterally out from under the
carbon sheet and carried over the upper end of the cover A. The section upon
which the memorandum was primarily written is then severed from the fixed
section or copy' by tearing the loaf along the line of perforations e.
The copy_c
of the memorandum is retained in the book, as shown in Fig. 4,of the drawing. In
carrying the aforesaid memorandum leaf from under the carbon sheet the latter is
allowed to drop onto the succeeding folded memorandum leaf. To bring this leaf into
its requisite position for entering the next memorandum the user of the book inserts
his pencil between the two sections of said folded leaf at the upper end thereof and,
by drawing the pencil down to the line on which the leaf is folded, the upper section
of each leaf is drawn out from under the carbon sheet and the memorandum leaf is
thrown into a distended position. Then the section of said leaf which has been
drawn out as aforesaid is thrown over upon the carbon sheet and the book is in
condition for entoring a memorandum.
In the book shown in Figs. 2, 5 and 8 of the drawing, all the memorandum
leaves lie with their entire length successively one upon the other and therefore in
using this book the fly or free end portion of the uppermost memorandum leaf bas
to be thrown up and onto the top of the carbon sheet and after the memorandum
has been written upon said portion of the leaf it is to be drawn out laterally to
carry the copy or fixed end portion of the leaf from under the carbon leaf, which
then falls upon the next memorandum leaf as hereinbefore described. The section c
which contains the original entry is then torn from the section e' containing the
copy, and the latter is left in the book. The memorandum leaves are provided
with a line of perforation e across the central portion thereof where the leaves are
to be severed.
U
The book illustrated in Figs. 3, 6 and 9 of the drawing is made up of single
memorandum leaves arranged in pairs c c. The primary leaf c is provided with
two lines of perforations e e respectively at the upper end or close to the clamp C
and a suitable distance from the lower end to form a detachable voucher and the
succeeding companion leaf c' has the line of perforatione at a proper distance from
the upper or fast end of the leaf to form a stub t which receives a copy of the
memorandum written on the top portion of the overlying leaf o and is rotained in
the book.
In using this book the uppermost memorandum leaf is to be raised so as to allow
the carbon sheet to drop onto the underlying leaf and then the top leaf is to be laid
upon the carbon sheet. After the memorandum has been written on the top-leaf c
the same is torn out of the book on the line of perforation e adjacent to the clamp C,
then the carbon sheet is to be raised and the underlying copy leaf o' is to be drawn
to the side opposite that on which the bar d lies until the said leaf c is drawn
completely from under the carbon-sheet, the main portion of said leaf is then
separated from the stub and the latter is loft in the book.
Figures 10 and 11 show a book which is designed to produce two separate copies
of the original writing in the book.

page_text: The leaves of the block are arranged in sets of three each. The first and third
leaves c and c' of each set are provided. with the row of perforations e near the
clamp where they are to be separated from the book, and the intermediate leaf c"
is of tissue paper and designed to be retained in the book.
с
In connection with this book I employ a carbon sheet faced with carbon on
both sides. This carbon sheet is interposed between the second and third leaves of
the set, and in writing the memorandum on the top leaf c the third leaf receives a
fac-simile of the memorandum and the intermediate tissue paper receives said
impression reversed on its underside, but the transparency of the paper allows the
improssion to be easily read from the upper side thereof. In the use of either of
the described books, the clasp a affords a handle by which to adjust the carbon
sheet without handling the same, and each of said books retains therein a copy of
the memorandum.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
1-The combination, with the memorandum book having its leaves bound
together at one end, of a rod attached at one end to said book at the fixed ends of
the memorandum leaves and extending along only one side of the book, a clamp on
the free end of said rod, and the carbon sheet attached to said clamp and lying with
its free end normally adjacent to the fixed ends of the menorandum leaves whereby
the uppermost copy-leaf may be drawn out laterally from under the carbon sheet
and severed from the book and a memorandum retained in the book as set forth.
2-A manifold memorandum book having its leaves arranged in sots of three
each, the top and bottom leaves of each set having rows of perforations to facilitato
the sovering thereof from the book, the intermediate leaf being of tissue paper, and
a sheet faced with carbon on both sides and inserted between the tissue paper and
subjacent copy-leaf, substantially as described.
Dated this 31st day of December 1892.
