Improvements in Means for the Protection of Books.
I, ARCHIBALD CONSTABLE, of 14 Parliament Street in the City of Westminster,
Publisher, do hereby declare the nature of my invention to be as follows:-
My invention has for its object to provide means whereby books are efficiently
protected against the destructive effect of dust, wet hot winds or insects and is more
especially intended for the protection of books in such manner that they can be
stocked in situations where they would otherwise be injured by exposure. Accord-
ing to my invention I enclose the books in a casing or covering made of a material
which is waterproof and impervious to insects and which is also transparent or
sufficiently so to enable the lettering on the book cover or on its cover wrapper to
be seen therethrough. A suitable material for the protecting cover or casing is
waxed paper the cementing material which is used to secure the cover or casing
together so as to prevent access of wet dust or insects being preferably of a vegetable
nature and prepared so as not to be attacked by insects.

COMPLETE SPECIFICATION.
Improvements in Means for the Protection of Books.
I ARCHIBALD CONSTABLE of 14 Parliament Street in the City of Westminster
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 :-
My invention has for its object to provide means whereby books are efficiently
protected against the destructive effect of dust, wet, periodical hot winds, insects,
or like injurious influences, and is more especially intended for the protection of
books in such manner that they can be stocked in countries, or situations, where
they would otherwise be injured by exposure. My invention for instance is
especially suited for the protection of books to be exported to, and stocked in, India
and like places. According to my invention I enclose the books in a casing, or
covering, made of a material which is waterproof, and impervious to insects, and
which is also transparent, or sufficiently so to enable the lettering on the book
cover, or on its "capping wrapper," to be seen therethrough. A suitable material
for the protecting cover, or casing, is waxed paper, that is paper treated with
mineral wax, the cementing material which is used to secure the cover, or casing,
together so as to completely enclose the book, and prevent access of wet, dust, or
insects, being preferably of a vegetable nature and prepared so as not to be attacked
by insects; such as by using in its composition an ingredient obnoxious to those
insects which infest places in which the books are to be stocked. In providing a
book with the protector according to my invention; the book after being stitched,
or bound, and after it leaves the "forwarder," may have applied to it an ordinary
paper "capping wrapper" for the protection of the covers, the said wrapper when
used having printed, or marked, upon it the title, or other particulars, of the book.
A sheet of the waxed paper is then taken and cut if necessary to the required size
to completely envelope the book and leave sufficient margin to overlap and receive
the cementing material. The said shect is then warmed sufficiently to soften the
ID 171

page_text: waxed texture thereof to prevent its cracking when folded. As it is folded to form
the casing each fold is cemented carefully and, if necessary, a clamp is, or
clamps are, used to retain the folds in position until the cement has set, or dried,
sufficiently.
Owing to the transparent character of the casing of waxed paper, the title, or
other particulars, on the book, or its capping wrapper, can be seen through the
casing and thus there is no necessity for attaching any label to the casing. Any
address, or direction, for the delivery of the book for instance, can be enclosed in
the casing and be seen through the material thereof, or an ordinary paper wrapper
may be used open at both ends so as to serve for postal or other purposes.
If desired the casing can be made first on a mould the size of the book and with
a side, or end, left open for the reception of the book; a piece of the material of
the casing being left so that, after the book is inserted, the said piece can be
folded over the said side, or end, and be then securely cemented to entirely enclose
the book.
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 :-
A protective casing for books, the said casing being made of a material, and in
the manner, substantially as herein before described.
