Improvements in Press Copying Books.
A communication by WILLIAM A. COOKE, Jr., of Brooklyn, in the County of
Kings and State of New York, United States of America, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster, and High Holborn in the County
of Middlesex, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to books for taking press-copies of letters, invoices and
other writings.
The object of the invention is to produce clean, clear and perfect copies
throughout the entire book, and to this end it consists in a press-copying-book
made up of sections, each consisting of from twenty to twenty five leaves of
copying-paper, and the sections separated from each other by interleaved sheets of
heavy non-copying paper, preferably oiled paper, or other suitable pliable non-
copying paper, the sections and interleaved sheets being bound together as a book.
It further consists in a press-copying-book composed of sections, and sheets of
bard surfaced paper separating the sections, which sheets are extended beyond the
front of the book and cut and lettered to form a projecting index, thus furnishing the
sections with an index-letter or letters whereby a section will be devoted to all
the papers falling under the index letter or character of the section, and thereby
the finding of any letter or other paper copied in the book will be greatly
facilitated.
The book is made up of any practicable number of sections, each of which is
composed of a sufficient number of leaves of copying-paper.
Between the sections are inserted sheets of hard surfaced non-copying and
practically non-elastic paper or other suitable material,-preferably however these
sheets should be of oil-board or paper of no very great thickness or weight, but
non-elasticity is an essential quality. These sheets may be conterminous with the
leaves of the book, but it is preferred that at the front they shall extend outside
of the book and cut to form an index running diagonally through the book, and
furnished at the projecting edge with index characters whereby each section has
an index character under which all the copies made in that section may be arranged
to fall.
The sections and their separating sheets are all bound together in covers in
regular copying book form.
The interleaved sheets break up the continuity of the body of spongy or elastic
copying leaves, thus reducing the elasticity of the whole body and contining it to
the thickness of the sections only, and these sections placed between the non-elastic
sheets, the force of the pressure is exerted through the said sheets and this force is
felt to the same extent as near the outside covers, whereby the air between the
leaves of the sections is expelled and the leaves pressed closely and forcibly
together.
When a writing is placed in any one of the sections, near or remote from the
covers, it is forced in contact with the copying-leaf, and a clear, clean and perfect
copy can be obtained at the centre of the book as at or near the covers, and with

page_text: no more force applied to the press than is usually available in an office where the
clerks who do the copying are generally girls or boys.
The index feature of this invention facilitates greatly the finding of copies of
writings. Each section having its own index character and all the papers falling
under a character being copied in the section to which that: character applies, it is
evident that a copy can be found much more quickly and easily than where a
general index is used for the whole book.
By a proper division of the index characters among the sections, the filling up of
the sections may be made approximately uniform.

A communication by WILLIAM A. COOKE, Jr., of Brooklyn, in the County of
Kings and State of New York, United States of America, Manufacturer.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6 Bank Street, Manchester
both in the County of Lancaster, 118 New Street, Birmingham in the County
of Warwick and 31 High Holborn in the County of Middlesex, Civil Engineer,"
do hereby declare the nature of this invention and in what manuer the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to books for taking press copies of letters, invoices and
other writings.
The object of this invention is to insure the production of clear, clean and
perfect copies of writings in any part of a press-copying book by means of the
ordinary copying-press operated in the usual manner, and it consists in a press-
copying book having a series of platens bound in with the book made of a hard
surfaced inelastic and more or less flexible material, introduced between the leaves
of the book at suitable intervals so that the leaves under each platen shall be
subjected to approximately the same pressure as the leaves directly under the
press platen whereby the elasticity and sponginess of the copying leaves will be
overcome, the air expelled and a close contact between the copying leaves and the
writing to be copied in any part of the book obtained.
It further consists in a press-copying book having platens of hard surfaced
inelastic and flexible material introduced between the leaves and bound in with the
book and which are extended out beyond the front edge of the book, and the
projecting edges provided with index characters.
Fig. 1 represents a plan of this improved press-copying book spread open and
exhibiting a platen bound in with the book, and
Fig. 2 is an end view of the same.
Referring to the drawing, the book B is made up of any particular number of
leaves of copying paper, and between the leaves are inserted platens C of
hard-surfaced non-copying and practically non-elastic, but more or less flexible
material preferably oil-board or similar material of no very great thickness or
weight.
The platens divide the book into a number of parts or groups a, b, c, &c.,
x, y, z, &c., each of which contains from 20 to 25 leaves. These platens may be
conterminous with the leaves of the book, but it is preferred that at the front they
shall extend outside of the book and cut to form an index I, running diagonally

page_text: through the book, and furnished at the projecting edge with index characters
whereby each part or group of leaves has an index character under which all the
copies made in that group may be arranged to fall.
The parts or groups and the platens are all bound together in covers D D and
back E in regular copying book form.
The interleaved platens C break up the continuity of the body of spongy or
elastic copying leaves, thus reducing the elasticity of the whole body, and by means
of the non-elastic platens, pressure is exerted on the leaves in the groups, and this
pressure is approximately the same in extent as that of the press platen on the
upper leaves of the book, whereby the air between the leaves of the groups is
expelled, and the leaves pressed closely and forcibly together. When a writing is
placed on a leaf in any one of the groups, near or remote from the covers, in
is forced in contact with the copying leaf, and a clear, clean and perfect copy cau
be obtained at the centre of the book as at or near the covers, and with no more
force applied to the press than is usually available in an office where the clerks who
do the copying are generally girls or boys.
The index feature of this invention facilitates greatly the finding of copies of
writings. Each group of leaves having its own index character, and all the papers
falling under a character being copied in the group to which that character is
applied, it is evident that a copy can be found much more quickly and easily than
where a general index is used for the whole book. By a proper division of the
index characters the filling up of the groups may be made approximately uniform.
The platens being of a hard unyielding nature make the binding of the book much
stronger and more durable as they serve as clamps between which the copying
leaves are held firmly.
Having now particularly described and ascertained the nature of the said inven-
tion, 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 :-
First. As an improvement in press-copying books, a book composed of any
number of copying-leaves, which are divided into parts or groups by platens made
of non-elastic material, the leaves and platens being bound together in a book,
substantially as specified.
Second. In a press-copying book, the combination of groups of copying leaves
and platens of hard surfaced non-elastic material, bound in the book between the
groups, substantially as specified.
Third. In a press-copying book, the combination of groups of copying leaves
and platens of hard surfaced non-elastic material bound in the book between the
groups and projected outside the front edge of the book, and having their edges
cut to form au index, substantially as specified.
