PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Covers for Books and the like,
and in the Means or Apparatus employed therein.
I EUSTACE FRITH, of North Albert Road, Reigate, in the County of Surrey,
Photographic Publisher, do bereby declare the nature of this invention to be as
follows:--
The invention is designed to effect the production of a cover for a book or the
like from one continuous piece of "board" or other suitable material the hinges
and back being produced from the rigid material of the primary sheet by pressure,
creasing, or crushing thereof at the parts to be rendered pliable and if desired at
the same time to produce name or other panels or space for title or the like.
The requisite creasing to give pliability or flexibility in the desired direction, to
the sheet may be effected by means of a top and a bottom die each die projecting
where the other is recessed so that ridge and furrow is produced and where the
hinges for the sides of the cover come, I preferably form a trough crease so as to
give the utmost possible flexibility and to minimise danger of fracture in use, of
the material.
Or the creasing and pressure may be effected by means of rolls, or a combination
of dies and rolls, performing the same functions as the dies alone and constructed
in analogous fashion.
For a book cover the sheet of material so treated may be decorated to taste to
resemble leather or cloth and be gilded, or otherwise ornamented and be connected
to the body of the book in the usual or other convenient manner.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Covers for Books and the like,
and in the Means or Apparatus employed therein.
I EUSTACE FRITH, of North Albert Road, Reigate in the County of Surrey,
Photographic Publisher 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 :-
The invention is designed to effect the production of a "case" or cover for a
book or the like from one continuous piece of "board" or other suitable material
the hinges and back being produced from the rigid material of the primary sheet
by pressure, creasing or crushing thereof at the parts to be rendered pliable.
The requisite creasing to give pliability or flexibility in the desired direction to
that portion of the sheet arched so as to form the back may be effected by means
of a top and a bottom die each die projecting where the other is recessed so that
ridge and furrow is produced and where the hinges for the sides of the cover come,
I form a trough crease by means of a machine such as is described and illustrated
in the Specifications of Patents Nos. 12043 and 23735 of 1892 granted to Teodor
Remus, so as to give the utmost possible flexibility and resilience and to minimise
danger of fracture in use, of the material.

page_text: Or the creasing and pressure to produce the arched back may be effected by
means of rolls, or a combination of dies and rolls, performing the same functions
as the dies alone and constructed in analogous fashion.
For a book cover the sheet of material so treated may be decorated to taste to
resemble leather or cloth and be gilded, or otherwise ornamented and be connected
to the body of the book in the usual or other convenient manner.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews a perspective view of a book cover, separately from the book or
contents.
Fig. 2 shews an edge view of a book with cover thereon, which cover it will be
seen is in one continuous piece.
Fig. 3 shews a cover as it appears from the back with the book opened
and in this example two lettering panels are shewn as being pasted over the
arched back.
Fig. 4 shews an example of the adaptation of the invention to form a filing case
and Fig. 5 shew's another form of the application of the invention to a stationery
case.
In the first instance a stiff sheet of "board" is taken and, by means of dies,
creases are made as at a, a, a, weakening the rigidity of the material but not
decreasing its tensile strength on the contrary the material will be found less liable
to tear where it has heen creased than elsewhere.
For a book cover, in order to provide for the greater play for folding required
at the junction a' of the rigid sides and the now flexible cover, deeper creases of
trough form are made there."
By the use of such machinery as is described in the Specifications of Teodor
Remus dated and numbered respectively 12,043, 28 June 1892 and 23735,
December 23rd 1892 I am enabled to produce the creases a and a¹ of the proper
form and possessing the requisite properties.
The creases a may be produced by means of pressure in dies the larger or
hinge creases a¹ being produced by the use of the aforesaid patented machinery.
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 I
claim is :-
As a new article of manufacture a case, or cover for use as described formed of
one continuous piece of leather-board, or like rigid sheet, the flexible hinges for
the sides and the flexible arched back being produced by appropriately arranged
grooves or creasings of the original sheet in the manner and for the purposes set
forth.
