[, GUSTAV GOLDSCHMIDT, Bookseller, of 44 Friedrich Str. Berlin, in the German
Empire, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
and in what manner the
OASES, COVERS OR BINDINGS FOR BOOKS AND THE LIKE
same is to be performed to be particularly described and ascertained in and by
the following statement
-
This invention relates to a metal cover case or binding for books and the like the
back thereof consists of a single piece and it has for its object greater durability of
the binding and facilitates moreover the stamping of title or similar indications upon
the back, or it allows the back to be perforated in casings for bound books so that the
title may be seen. Bindings for books as heretofore made and partly consisting of
metal have either had a back of cloth, leather, or the like and sides of metal, or sides
of cardboard or similar material and a back of metal divided and hinged in the
muldle.
The annexed drawings, shows in figs. 1 to 7 two forms of a metal casing or
covering and figs 8 to 11 a metal binding.
The metal case or covering is so made as to be removable and so represented in
figs 1, 2, 3, 4, 4, 4, 5 and 6 consists of a back a with which metal corners b b¹
are connected by lunges; the corners 6 b' embrace the covers of the book as shown
in the drawings. Two of the hinges (say at top and bottom) are fixed, whilst the
other two are so made that when the covers of the book are in a certain position
they may be moved allowing the edges of the parts engaging with the book-covers
to be raised clear of the latter so that the entire metal covering or case may be
removed. To this end the part c of the bottom hinge, fixed to the back of the cover
or case, has a slot f corresponding to pin d It is evident that when pin d and
slot face one another the corner pieces may be raised 30 far that the covers of the
book are released (see the position shown in dot and dash lines fig. 1). When the
upper corners are released the lower ones are simply pushed off the book and
the metal cover or case is removed from the book. The operation of removing the
metal cover and the construction of the sliding hinge are shown in figs. 3, 4, 4.

page_text: Fig 2 shows a plan of a book fitted with such a case or cover, Fig 4b being the back
and corners spread out.
The form illustrated in figs. 5, 6, and 7 consists of a curved plate of metal g which
forms the back and has perforations or apertures h showing the title of the book
to which the case is applied. Fixed hinges connect the sides of this case or cover
with the back The side poitions form a frame open at top and enclosing the covers
of the book. The part of the frame is by a hinge e fixed on the portion k of the
frame and a fastening m serves to secure the frame upon insertion of the book.
The metal binding for books shown in figs. 8, 9 and 10 embodies the same
principle, and is extremely simple and durable Like the case or cover above
referred, covers or sides o o¹ are attached by hinges. On the inside of the cover
near to the hinges a strip of metal is so secured as to form a slot or recess between
the cover and the strip. The book being properly stitched is secured in the
binding as follows: The cords p projecting at the sides as usual are spread out and
secured between two stripes of card board q. q' (fig. 11) and if necessary glued or
cemented thereto The strips of card board, with the cords between are now inserted
between the cover and the inner strip of metal and connected by punching bosses
in the metal or by rivets as shown in figs. 8, 9 and 10
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same 1s to be performed I declare that what I
claim is
66
"
A cover, case or binding for books consisting of a back formed by a single piece
of metal to which corners, sides or covers are attached by hinges the whole con-
structed and arranged as specified and shown in the drawings and serving either as a
temporary, removable cover for the book or as a permanent binding.
