Improvements in Bookbinding.
Year: 1898

page_text: I, ERNEST RIDLEY DEBENHAM, of the Firm of Debenham and Freebody, Wig-
more Street, London, W., Merchants, do hereby declare the nature of this inven
tion to be as follows:-
The invention consists in the manner of employing aluminium in the con-
struction of book covers, in place of the heavy and thick millboard now usually
employed whereby the covers are made stronger, thinner and lighter thereby
reducing the weight of the book.
In carrying out the invention one or two or more boards of aluminium may
be employed, if two one would be much thicker than the other, connected by
any suitable way to the thicker board would be the tapes and tongues for secur-
ing the covers to the leaves, and over such would be secured by cement or
rivetting the thinner sheet, the two sheets forming the foundation for the cover,
and bound over with the usual binding; or one board of aluminium and one of
millboard could be employed, the latter taking the place of the thinner metal
one.

Improvements in Bookbinding.
I, ERNEST RIDLEY DEBENHAM, of the Firm of Debenham and Freebody, Wig-
more Street, London, Merchants, 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 principally refers to improvements in the construction of book
covers, the object being to enable the covers to be made stronger, thinner and
lighter than has heretofore been common and especially when such book covers
have been made of heavy and thick mill-board as usual.
With these objects in view I make the boards or covers of aluminium and in
order that my invention may be readily understood I will describe same with
reference to the accompanying diagram drawings, whereon Fig. 1, is a vertical
section of such a book-cover and Fig. 2 is a plan of same.
According to my invention I preferably employ two sheets A and B, Fig. 1,
of aluminium, of which the sheet A, which will form the inner surface of the
cover, is thinner than the other sheet B.

page_text: These two sheets of aluminium A and B, are glued or otherwise fixed together
face to face as shewn, the tapes tongues, or the like, C, being securely embedded
between the said plates, rendering it impossible for the book so bound, becoming
detached from the covers except by the cutting of the tapes or the breaking up
of the covers.
In carrying out the invention the tapes or cords may be connected to the
thicker plate B, and over such tapes, the thinner sheet A, may be fixed either
by cementing as aforesaid or by rivetting. The boards so constructed may be
bound or covered with the usual binding material or not as required.
In some cases I may substitute for the aluminium plate A, a thin sheet of
ordinary mill-board.
Obviously if found more convenient a greater number than two sheets of
aluminium may be used to compose a binding board.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is;-
1. In book-binding, the construction of the book covers or boards, composed
of an outer sheet of aluminium, having the tapes, cards tongues and the like for
securing the covers to the leaves affixed on to the interior of the surface of the
said aluminium plate, in combination with an inner and thinner plate of alumi-
nium affixed upon the inner surface of the outer plate substantially as set forth.
2. In book-binding, the general construction and arrangement of parts com-
prising my aluminium covers or boards substantially as described with reference
to the accompanying diagram drawings.
