"IMPROVEMENTS IN FRAMES FOR
"
PRESERVING THE EDGES OF BOOKS, DRAWING SHEETS OR PAPERS
A communi-
cation to me from abroad by Honoré Théophile Brunet, and Jules Charles Devèze
both of the city of Paris in the Republic of France
The object of this invention is to protect copy, and other thin books, drawing
sheets and similar objects from being torn, frayed, soiled or bent up at the edges,
the appliances for this purpose are of two kinds.
J
The first comprises two parts, one being a thin paste board for the hand to rest
upon whilst writing or drawing, the other being a thin metal frame whose edges
and sides are bent up just the depth sufficient to accommodate the thickness of
the book, and card combined.
The edges of the frame are thicker than the flat parts to give strength and
rigidity to the frame.
'
The width of the frame would be just the width of margin of the book or paper
to be preserved
One of the sides of the frame is pierced with holes for the passage of twine to
fasten the book, or paper thereto; the opposite side has a clasp to fasten the whole
together
.
The second differs from the first only in that there are two frames one within
the other, the outer one having hinges on one side and a clasp at the other to fasten
like the first.
4.
The object of this double frame is to admit of two different sized books being
held in one and the same frame.

ARTHUR CHARLES HENDERSON of 47 Museum Street Oxford Street in the
Parish of Bloomsbury and county of Middlesex IMPROVEMENTS IN FRAMES FOR
PRESERVING THE EDGES OF BOOKS, DRAWING SHEETS OR PAPERS A communi-
cation to me from abroad by Honoré Théophile Brunet and Jules Charles Devèze
both of the City of Paris in the Republic of France
The object of this invention is to preserve the edges and sides of copy, or other
thin books or sheets of drawing paper or other sheets, from dirt, breakage, or dogs
ears so commonly the case in schools.
The copy book is placed in a metal or other frame which is made deep enough
to hold a single book, or it may contain more than one frame and books of different
sizes. In this case the first or external frame is made large enough to accommodate
a second frame placed within the first. . )
These frames are made of any width to adapt themselves to the various sizes of
the copy books, and the width of the sides of the frame or frames is regulated.
according to the width of margin round the book it is intended to preserve.
To the frame a double card or kind of portfolio (which may also be of metal,
and which serves as rest for the hand whilst writing) is attached by cords, catgut,
or wire passed through the edges or back of the portfolio and through holes made
in one of the bent up sides or edges of the metal frame.
The opposite side is furnished with a hasp which secures the whole together
when the copy book is not in use or when so employed, and is inserted in the
frame.
Fig 1 shows a frame of this description. Figs 2 and 3 being 'sections thereof
following the lines 1-2, 3-4. Fig 4 shows the larger one made to contain the
smaller one just mentioned Figs 5 and 6 are sections at 3-6, 7-8.
a Fig 1 is the card board or thin metal portfolio, being in dimensions just the
least bit larger than the copy book, it is intended to protect. b, is the metal
frame, the width of whose sides and ends would vary to suit the margin of the
book to be preserved, the depth being sufficient to receive the thickness of the
book and card or metal portfolio together..
The angles of the frame may be rounded. One of the sides is pierced with holes
as already inentioned by which and the cord x, which may also be thread or wire,
the card or metal portfolio a, is held to the frame b, whilst at the opposite side
is the hasp f, of metal, pivoting on one of the sides of the portfolio of card or
metal.
When the copy book is not in use it is placed between the cards or metal
sheets forming the portfolio, and the frame is then closed and fastened by
the hasp.
Figs 4. 5. 6. show in different views the large frame for the reception of the
smaller, just mentioned, the two frames are here shown by b. d, united by hinges
or by the use of a simple rivet serving as pivoting axis
The sides of the frames b. d bent up at right angles, box one within the other
and enclose within them, the card or metal sheets forming the hand rest and
portfolio a. f is the clasp firmly bolding the frame together when it is closed.
These two frames form a kind of box for containing the books and the card or
metal sheets as the case may be, which form the case or portfolio a, the first
frame d, has an opening larger than the second b, which it encloses.

page_text: The clasp or fastener fis connected to the frame d, the angles of which latter
are rounded, the flat parts of the frame are thinner than the bent up parts or rim
which are made thicker for strength.
In Fig 4, by the dotted lines are shown a rim with which the card or metal
sheets a, are provided to prevent the copy book slipping, and to facilitate placing
it in position in the frame: the angles formed by this rim are marked r¹.
When the copy book or books as there may be many of different sizes are not in
use they are enclosed in the portfolio forming the hand rest; and when in use the
book rests on the portfolio and the margin is protected by the frame as previously
mentioned.
Either side of the frame may be used according to whether a small or large book
is used. Although only two forms of frame are shown as example, it is needless-
to say that these frames may be made any size desired.
The frames may be cut from a sheet of metal, or be made of a band of steel, iron
or copper with the edges and the angles bent up, which latter parts are made
thicker for strength.
Claim is made to the metal frames b. d. for containing copy or other thin books
or sheets of drawing or other paper, the width of the frame being made in
accordance with the margin to be protected from dirt, breakage or rubbing. The
frame or frames being made with bent up edges, and where more than one is used
being so arranged as to box one within the other for containing the card or metal
sheets forming the portfolio and hand rest a, and the copy books, the depth of
the frame being constructed to accommodate both
In witness whereof I the said Arthur Charles Henderson have hereunto set
my hand and seal this fourth day of January in the year of Our Lord One
thousand eight hundred and eighty four
