I, EDWARD LE MOYNE HEYDECKER, of No. 111, Broadway, in the Borough of
Janhattan, City of New York, State of New York, United States of America,
Lawyer, 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 relates to books and temporary binders and has for its objects
to provide for the amendment of books already printed and bound in such man-
mer as to produce a practically new book without any portions therein of the
parts it is desired to omit and to provide binding means whereby a separable
book may be produced capable of being taken apart for the removal or insertion
of leaves at any parts thereof and yet a satisfactory book for handling and using,
resembling closely in appearance an ordinary permanently-bound book; and my
invention includes various improvements in separable books and temporary
binders, including a movable connection between the holding means and cover,
whereby in the ordinary movements of the cover the clamping devices of the
holding means are covered or concealed, but by reason of this movable connection
a small additional movement permits access to these clamping devices for the
purpose of taking the book apart. My invention has other objects and advan-
tageous features and includes various improvements, all of which will now be
particularly described with reference to the accompanying drawings.
Figure 1 is a transverse section on a plane indicated by the line 2 2, Fig. 3,
but with the book closed, of a separable book embodying my invention. Fig. 2
is a similar view, but with the upper cover open and moved rearwardly, so as to
permit access to the clamping devices. Fig. 3 is a plan view of the book as
shown in Fig. 2.
The holder shown includes a front clamping-bar 4 and a rear clamping-bar 5
and binding-pins 6, and the binding-pins may be secured to one of the clamping-
bars and are shown as secured to the front clamping-bar 4. The leaves 7 are
preferably separate sheets and are suitably perforated near their back edges and
O placed over the binding-pins 6, and they are clamped together by clamping
devices or nuts 8 8, which are screwed over the clamping-pins 6 and bear upon
clamping-bar 5. The number of binding-pins may be varied for differiut
lear

page_text: sizes of books three binding-pins being most frequently employed. The covers 9
and 10 are hinged to the holder at the front edges of the clamping-bars, so as
to be angularly movable relatively to the holder. One of the covers, and as
shown the front cover 9, has a simple hinge connection with the corresponding
clamping-bar, such connection being shown as formed by the hinges 11, of which
one is shown, formed partly by lugs extending forwardly from the clamping-
bar and partly by a lug extending rearwardly from the hinge-bar 12, the
hinge-bar 12 being secured to the front cover by a bent staple or clasp 13 and
passing between the two boards forming the cover. The other cover (shown as
the rear cover 10) has a hinge connection with the corresponding clamping-bar 5
and is also movably connected thereto, so that it may be moved rearwardly to
permit access to the clamping devices, the hinge connection being shown as
formed by the hinges 14, of which one is shown, each partly formed by the hinge-
bar 15 and corresponding to the hinges 11; but the hinge-bar 15 has a sliding
connection with the cover, shown as formed by the bent staple or clasp 16, to
permit the above-described movement of the cover. The sliding hinge-bar 15
is of uniform width in the parts which move through the clasp 16, but increases in
width, so as to form a shoulder 17 at the point where it is desirable to arrest
its sliding movement. The number of hinges at the front and back of the book
may be varied for different sizes of books, two hinges at the front and two hinges
at the back being most frequently employed.
The flexible back 18 of the book is shown as secured to the covers, and may
be secured thereto in any usual or desired manner. Should it be desired to
attain the usual rounded appearance of the back of an ordinary book, this back
may be padded or may have a wooden or leather block inserted therein in any
well-known manner.
In the crdinary use of the book the sliding hinge-bars 15 will be pushed in to
their full extent, as shown in Fig. 1, and the covers will open on the hinges 11
and 14 in about the same position as the covers of an ordinarily-bound book,
and the book will not materially differ in appearance from an ordinary book.
Only the front edges of the clamping-bars will be visible, and the clamping
devices or nuts will be covered and entirely concealed. When, however, it is
desired to amend the book, the cover having the movable connection is opened
and then pulled rearwardly to the position shown in Fig. 2, and thereby the
clamping-bar and clamping-nuts will be completely uncovered, and the clamping-
nuts will now be readily accessible and may be unscrewed and the clamping-bar
lifted off from the binding-pins, and all or any number of the leaves taken out
and new leaves inserted, as may be desired. At the conclusion of this operation
the rear cover may be pushed forward to the hinges and the book thus restored
to its normal condition.
It will be evident that the devices embodying my invention are well adapted
either for permanent or temporary binders. The binding-pins 6 may not be
secured to the front clamping-bars 4, so that the binding-pins may be removed
when desired, and other binding-pins of different length substituted therefor.
Should it be desired to take the book apart from its front, then the threaded
ends of the binding-pins and the clamping-nuts thereon would be at the front
of the book, the pins being thus reversed from the position shown and the front
cover would have the sliding hinge-bar, and should it be desired to take the book
apart from both ends then the binding-pins would be provided with clamping-
nuts at both ends and the hinge-bars at both the front and the back of the book
would have sliding connections with the cover. It is evident that other modifica-
tions may be made in the construction within the purview of my invention.
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
