Year: 1880

page_text: LETTERS PATENT to William Hawtin, junior, of the Firm of William Hawtin
& Son, of Paternoster Row, Account Book Makors, and Augustus Delves
Collier, of Camberwell, in the County of Surrey, for an Invention of
"IMPROVEMENTS IN FORMING THE BACKS OF ACCOUNT AND OTHER BOOKS IN
BINDING THE SAME,"
PROVISIONAL SPECIFICATION left by the said William Hawtin and
Augustus Delves Collier at the Office of the Commissioners of Patents on
the 6th July 1880.
WILLIAM HAWTIN, junior, of the Firm of William Hawtin & Son, of Paternoster
Row, Account Book Makers, and AUGUSTUS DELVES COLLIER, of Camberwell, in
the County of Surrey. "IMPROVEMENTS IN FORMING THE BACKS OF ACCOUNT
AND OTHER BOOKS IN BINDING THE SAME."
This Invention relates more particularly to improvements in forming the backs
of account books, although the same is applicable to the binding of other books,
and our object is so to form or construct the back part which connects the two
sides that when an account book is opened the inner part forming the folds of the
section will present a level surface, and so that it can be written upon and read at
each inner edge of the leaves without difficulty.
For this purpose in place of forming the back of the binding with card board
and paper bent into shape as heretofore, according to our improvements the back
is formed from a piece of steel or other suitable metal bent to the shapo desired,
In the operation of binding the
and having flaps hinged to each edge thereof.
hinged flaps are inserted into or otherwise secured to the millboard or other
material which forms the sides of the binding, so that when the book is opened the
strength of the hinged or jointed parts forces the folds of the sections up to a lovel
with each other.
In addition to the advantage of obtaining a level surface between the sections
when the book is open, the back will last the entire wear of the book without
becoming soft or giving way as ordinary backs made of millboard frequently do.
The binding may be finished in the ordinary manner.

the said William Hawtin and Augustus Delves Collier in the Great Seal
Patent Office on the 6th January 1881.
WILLIAM HAWTIN, junior, of the Firm of William Hawtin and Son, of Paternoster
Row, Account Book Makers, and AUGUSTUS DELVES COLLIER, of Camberwell,
in the County of Surrey. "IMPROVEMENTS IN FORMING THE BACKS OF ACCOUNT
. AND OTHER BOOKS IN BINDING THE SAME."
This Invention relates more particularly to improvements in forming the backs
of account books, although the same is applicable to the binding of other books,
and our object is so to form or construct the back part which connects the two
--sides that when an account book is opened the inner part forming the folds of the
sections will present a level surface, and so that it can be written upon and read-at
each inner edge of the leaves without difficulty.
For this purpose in place of forming the back of the binding with mill board
and paper rolled into shape as heretofore, according to our improvements the
back is formed from a piece of steel or other suitable metal a bent to the shape
desired, and having flaps a hinged to each edge thereof, as represented in section,
Figure 1 of the Drawing hereto annexed, Figure 2 being a plan and section on a
smaller scale, and Figures 3 and 4, end views showing its application to an account
or other book.
In the operation of binding the hinged flaps a' aro inserted into or otherwise
secured to the mill board or other material which forms the boards or sides of the
-binding; so-that-when the book is opened the strength of the hinged or jointed
parts forces the folds of the sections up to a level with each other.
It will be seen that the flaps a', a', are perforated, so that the splits of the
mill-boards are firmly united together at those parts where the flaps a¹, a', are
enclosed therein.
In addition to the advantage of obtaining a level surface between the sections
when the book is open, the back will last the entire wear of the book without
becoming soft or giving way as ordinary backs made of mill-board frequently do.
The binding may be finished in the ordinary manner.
Having thus described the nature of our improvements, and the manner in which
the same is carried into practice, we would have it understood that we do not
claim any parts of the parts separately, which are well known and in common use,
neither do we claim the forming of the bent back a of metal, but what we do
claim is,―
The improved method of forming or constructing the backs of account or other
books with a bent metal back a combined with binged flaps a', a', substantially in
the manner and for the purpose hereinbefore fully described and represented in the
Drawings hereto annexed.
In witness whereof, we, the said William Hawtin, junior, and Augustus Delves
Collier, have hereunto set our hands and seals, this Fifth day of January, in
the year of our Lord One thousand eight hundred and eighty one.
WILLIAM HAWTIN, JUNIOR.
AUGUSTUS DELVES COLLIER.
