A Novel Mode of Detecting the Misplacing or Removal of any Leaf
or Leaves or Documents when Bound or Connected Together in
the Form of a Book.
We, JOSEPH HENRY BETTELEY of No. 42 Old Broad Street London, E.C.,
Engineer, and ROBERT JOSEPH RASTRICK of. Chesterfield, Elm Grove, Southsea,
Gentleman, 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
-
Our invention has for its object the detection of the surreptitious or fraudulent
removal of cheques, drafts, bills or similar negociable instruments from the books in
which they may be bound or connected together.
According to one method of carrying out our invention, we remove a portion of
the margin or margins of the leaves, in a manner similar to that adoped for indexing
books, that is to say the last leaf at the end of the book will have only a small
portion of the margin or margins thereof cut away, or just sufficient to expose part
of the cover or wrapper of said book; the next leaf would have a larger portion
removed, and so on, removing in progression a larger portion of each leaf until the
first is reached, which latter would have the whole of the margin or margins
removed.
Another method which we adopt in accordance with our invention, is so to arrange
the leaves of a book made up of cheques, drafts, bills or like negociable instruments,
that they shall form a broad bevel at one or more of the edges; or the bevel may be
formed on the front top edge, and another bevel on the back bottom edge. Arranged
in this latter way, a bevelled edge would be always visible, whether the book be laid
upon its face or upon its back. Instead however of the edges of the book being
bevelled, we may bevel one or more of the corners; or, we may form one or more
notches upon any convenient part of the edges or margins, said notches being bevelled,
and of rectangular, square or of any other desired shape or conformation.
Having prepared the leaves of a book in the manner above described, we mark the
margin or margins thereof, or bevelled edges with one or more colors, preferably
dark, or we may print thereon in any suitable color or combination of colors, an

page_text: ornamental design, such as for instance a greek bordering or analagous distinctive
mark.
It will be obvious therefore from the foregoing, that the removal of a leaf from a
book made up and arranged in the manner described above, would cause a break in
the continuity of the colored margins or edges, and an unclosed vacant space would be
exposed to view, thus calling attention to the misplacement or removal of a leaf or
leaves of said book.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed we declare that what we claim is :-
The novel mode of and means for detecting the misplacement or removal of any
leaf or leaves or documents when bound or connected together in the form of a book
substantially as herein described and set forth.
