COMPLETE SPECIFICATION.
Improvements in or in connection with Account' Books, Pay Sheets,¨*
Charts and the like.
We, JOHN FRANKLIN BROWN, residing at 143 Dowling Avenue, In the City of
Toronto, in the County of York, and. Province of Ontario, Canada Manufacturer,
and ANSON O. KITTREDGE, residing at 257 Edgecombe Avenue, in the City, County
and State of New York, United States of America editor, 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.
This invention in part relates to certain new and useful improvements in that class
of account books composed of wide and narrow leaves, or long and short leaves alternately
arranged, of which the wide or long leaves overhang the edges of the narrow or short
leaves, and in part also relates to sheets of paper of uneven thickness for various other.
purposes and the object of the invention when applied to book making is to so
construct the wide or long leaves that that part of them adjacent to the *narrow
leaves will be of an ordinary thickness or, in other words, of the same or nearly the
same thickness as the narrow or short leaves, whilst that part of them overhanging
the edges of the narrow or short leaves will be of an increased thickness, equal to the
thickness of the narrow or short leaves interposed-between- two adjacent wide or
long leaves; the whole device being-hereinafter more fully set forth and more
particularly pointed out in the claims.
In the drawings:
Figure 1 is a perspective view of an open account book, consisting of wide leaves
and two narrow leaves interposed between each adjacent pair of wide leaves.
Figure 2 is a cross sectional view through two narrow leaves and an adjacent wide
leaf.
Like letters of reference refer to like parts throughout the specification and
drawings.
A represents an account book composed of narrow leaves and wide leaves, the wide
leaves overhanging the edges of the narrow leaves.
The principal objection to books of this description has heretofore been that the
unsupported edges of the leaves drop and occasion wear and tear, presenting .an
ungainly appearance, and, in addition, rendering it difficult, if not impossible, to
write on the edges of the wide leaves.
a represents one of the narrow leaves of the book A, and b one of the wide leaves.
The narrow leaf is of the same thickness throughout its length and breadth, whilst
the wide leaf b is of two unequal thicknesses. That portion of the wide leaf b
adjacent to the narrow leaf a is of the same thickness as the narrow leaf, whilst that
portion b¹ of the wide leaf extending beyond the edges of the narrow leaf is of an
increased thickness equal to the thickness of the thin portion of the wide leaf and of
the narrow leaves interposed between it and the overhanging edge of the next
adjacent wide leaf. In other words, if the wide leaves and narrow leaves are
alternately arranged the part of the wide leaves extending beyond the edges of the
narrow leaves will be of a greater thickness than the part adjacent to the narrow
leaves. If several narrow leaves are interposed between two adjacent wide leaves, the
+4-

page_text: extended part of the wide leaves will be of a thickness equal to the thickness of the
thin part of the wide leaf and the thickness of the interposed narrow leaves. By
constructing the wide leaves in this manner it is possible to build up that portion
of the book extending beyond the edges of the narrow leaves, to the same thickness
and degree of density as the body of the book. By this construction the edges of the
wide leaves will be adjacent to each other and will permit of operations being carried
on without the employment of a rest.
-
This invention can be employed not only in connection with books, but also in
connection with loose sheets of paper of various widths, held together by clips or
temporary binders.
The invention is also adapted for that class of books known as perpetual ledgers
or loose leaf ledgers, and is also applicable to pay-rolls, comparative tables, and
charts. In fact, it is part of our intention to apply this system of leaf building to all
purposes where wide and narrow leaves or long and short leaves are alternately
arranged...
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 :-..
A book consisting of wide,and narrow leaves, the wide leaves of two unequal
thicknesses, the narrow leaves and that portion of the wide leaves adjacent to the
narrow leaves of substantially the same thickness, and that part of the wide leaves
extending beyond the edges of the narrow leaves of an increased thickness,
approximately equal to the thickness of the thin part of the wide leaf and of the
narrow leaves interposed between two adjacent wide leaves, substantially as specified.
