COMPLETE SPECIFICATION.
Improvements in Binding-covers.
I, ADOLF MARTIN LEVISON, Stationer, of 50, Kjöbmagergade, Copenhagen, Denmark,
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 invention refers to a binding-cover in which anybody may bind loose leaves,
sheets, pamphlets, sheets of music, magazines and the like in exactly the same
manner as this is professionally done by the bookbinder.
The covers hitherto used for this purpose hold the previously perforated leaves
either by means of a metal-inechanism supplied with hooks, or they have narrow
paper-folds on which the leaves are glued, and lastly, only a partial binding takes
place by the leaves being pushed in under elastic strings or ribbons stretched along
the back of the cover.
The present invention differs from all these by being simply the well-known
implement of the bookbinder; the sewing-press (sewing-board) with its cords
(ribbons) fastened to the back of a cover.
The accompanying drawing shows such a binding-cover drawn perspectively and
also illustrates the way it is to be used.
In a common book-cover consisting of two card-board covers A and B mutually
connected by a stiff or pliable back C, a sewing-back D consisting of some stiff fabric
with open meshes having 3 or more strips or cords a glued on to it, is fastened
on to the inside of the upper-cover A close to the back. To the free edge of the
sewing-back a tuck E is fastened which may be pushed into a slit in the
lower-cover B.
In this binding-cover leaves, sheets or the like may be bound by sewing with a
stitching-needle and thread or by means of wire-clips by proceeding in the following
way:
The tuck E is set free by bending the covers A and B far back, the cover is then
laid on a table so that the lower-cover B is hanging down over the edge of the table
as shown in the drawing. The sewing-back D is straightened up so that it replaces
the sewing-press of the bookbinder and the sheets are now bound by sewing, the
thread being carried stitch by stitch alternately along the inside of the sheet and
along the outside of the sewing-back, or by means of inetal-clips which are forced
through the sewing-back and the sheet and beat along the inner side of the sheet.
When the tuck E is again pushed into the slit F the leaves sheet &c., will be as
solidly bound as by ordinary good book-binding.
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) A binding-cover for loose leaves, sheets, pamphlets or the like characterized by
a book-cover inside which a sewing-back D supplied with strips or cords is fastened
along one of the edges of the back and being detachable from the other edge of the
back, as set forth.

page_text: (2) In a binding-cover specifiel in Claim 1 the arrangement of a stiff tuck E
fastened on to the free edge of the sewing-back and which may be pushed into a
slit in the opposite edge B of the back and thus firmly hold the sewing-back to the
back of the cover, as set forth.
(3) A new or improved binding cover, substantially as hereinbefore described
and shown.
