Blank for Book Cover Protectors.
I, WILLIAM BEVERLEY HARISON, Publisher, a Citizen of the United States,
and residing at 59 Fifth Avenue in the City of New York, in the County of New
York, and State of New York, 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 object of my invention is to provide a blank for book cover protectors.
The invention relates to an improvement whereby the blank may be employed to
cover any book of ordinary size.
The invention consists in brief, of a sheet of paper, parchment or similar material
in sheets, provided with gum at any two opposite edges on one side of the
and at the corners of the paper on the opposite side of the sheet. One or two other
paper
details are also included in the construction.
By reference to the accompanying drawing, and the following description, the
invention may be easily understood.
Figure 1, is an inside view of the blank, the ends being turned over at A, to
strengthen these edges. Adhesive material, as gum arabic is applied at B.
Figure 2, represents the same with the two sides folded down at the dotted
lines C. In this view the corners D, where adhesive material is applied, are
exposed.
Figure 3, shows the manner of measuring the ends E, in order to determine the
length to be folded down at F.
Figure 4, is a view of a completed cover, the sides and ends having been folded
down, making the pockets G, for the covers of the book.
To make a cover or protector of this blank, the two sides are folded down as in
Figure 2, so that the width of the blank, when folded, is a trifle more than the
length of the book to be covered, from the top to the bottom. The gum as shown
at B, is then moistened and the fold fastened down. The book is next laid in the
cover as shown in Figure 3, and the two ends E slightly creased over the edges of
the book's cover at F, to indicate its size.
The book is then removed and the ends E, folded down at F, and fastened down
by moistening the gum at D.
The cover now presents the appearance shown in Figure 4 G, being pockets
formed by the folded over ends E. The book to be covered is now placed in
the cover by bending its covers back slightly, and thrusting them into the two
pockets G.
To strengthen or stiffen the cover, the ends or sides can be made of double
material or the whole cover reinforced with cloth or other material.
Guide lines can also be printed from side to side or end to end to assist in folding
evenly the sides or ends.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. Prepared material for book cover, consisting of a sheet of paper which is
provided with gummed surfaces at any two opposite edges on one side of the paper,
and with gummed surfaces at the corners of the paper on the opposite side of the
sheet.
2. A blank for book cover protectors, consisting of a rectangular piece of paper,
reinforced throughout or in part, by cloth or similar material attached thereto,
and turned over edges provided at the ends of the said piece of paper, which is

corners.
3. Prepared material for a book cover, consisting of a sheet of paper of sub-
stantially rectangular form provided with gum upon one side near two opposite
edges, and at the corners on the opposite side of the sheet, and with rulings parallel
to one another on that side of the paper on which is the first named gum.
Dated this 23rd day of March 1892.
