Improvements in Binders for Papers and the like.
I, HARRY EDWARD DADE, of Mount Vernon, in the County of Westchester and
State of New York, United States of America, Manufacturer, 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 binders and has for its object to provide an inexpen-
sive, convenient and reliable binder in which the sheets may be separately
inserted and removed. The invention consists of the combination of features
hereinafter set forth.
In the drawings forming part of this specification, and in which like numerals
of reference designate corresponding parts in the several figures, I have shown
several of the various embodiments of which my invention is susceptible.
Fig. 1 is a plan view of a binder embodying the invention.
Fig. 2 is a section on the line 2-2 of Fig. 1.
Figs. 3 and 4 are similar sections, showing modifications.
Figs. 5 and 6 are vertical sections showing two different forms of a sleeve
forming a feature of the invention.
Fig. 7 is a fragmental sectional view of a detail.
the covers
1 and 2 are binding strips generally, in practice, hinged in the usual way to
and 31, the cover 31 not being shown, as as to hold sheets of paper
or other fabric between the strips. The strip 1 is provided with one or more
posts fixed thereto, adapted to engage the sheets, as by entering holes or recesses
in the sheets. One at least of these posts is screw-threaded, so that if only one
post is used it will be threaded. In their preferred form the threaded post is
made of solid metal with exterior threads, but of course this particular form is
not always essential. In Figs. 1, 2 and 4 only two posts 4 and 5 are shown, both
being sheet engaging posts and both threaded. In Fig. 3 are shown two smooth
sheet engaging posts 6 and 7 and a threaded post 8 which may or may not engage
sheets, as desired. Each of the threaded posts in all the figures is provided with
a sleeve capable of sliding back and forth thereon and having expanding and
contracting faces adapted to mesh and unmesh with the threads on its post. The
sleeves are preferably made in the form shown, having interior threads to mesh
with the exterior threads of the posts. Thus, when the sleeve has its faces disen-
gaged from the threads of the post it may slide freely on the post and when it has
its faces engaged with the threads on the post it cannot slide on the post but
may be screwed up or down thereon until arrested. The sheets to be held on the
binder lie between the strips 1 and 2, the sleeve being above the strip 2 on its
post. In Figs. 1, 2, 3 and 5 are shown one of the various forms of sleeves that
may be employed. In these figures, 9 is the sleeve made in two halves 10 and 11,
which in this instance provide the expanding and contracting faces which are
adapted by the interior threads 12 formed thereon to engage and disengage with
the threads of the post, as the post 8. The halves of the piece 9 are separated by
slits 13 and are connected together near their top by the fixed circular spring 14,
so that the said faces may be expanded and contracted on the post, the springs
bending as the halves move to and from each other.
In Figs. 2, 3, 5 and 7, the strip 2 is shown as provided with a tapered cupped

page_text: seat to receive the lower tapered end of the sleeve 9. In Fig. 5 the cupped seat
is numbered 15. This cupped seat 15 and the tapered end of the piece 9 consti-
tute means for holding the expanding and contracting threaded faces in mesh
with the threads on the post. The cupped seat 15 slides freely along the post and
inasmuch as it is formed in the strip 2 it moves therewith.
In Fig. 6 is shown another form of the threaded sleeve. In this case the
sleeve 16 is constructed substantially like the sleeve 9, except that the two parts 17
and 18 are pivotally connected together by the pivot pin 19. In this case, more-
over, the cupped seat 20 is not formed on the strip but as a separate piece and of
such dimensions as to be capable of sliding freely on the post. While there are
important advantages in using the strip 2, yet its use is not always essential and
it may be dispensed with without departing from the scope of my invention. If
this strip 2 were not used the sheets could be held down by a sleeve and its cupped
seat either alone or in conjunction with any additional means suitable for the
purpose.
In the operation of the forms of the invention shown in the drawings, when
it is desired to remove a sheet from the binder, the sleeve is rotated until its
threaded faces have advanced sufficiently far along the post and outward from
the cupped seat, which holds these faces in mesh with the threads of the post, to
permit the faces to become disengaged from such threads of the post, when the
sleeve may be slipped freely along the post without further rotation. If two
threaded posts are employed, the sleeve of this second post will also be operated
in the same way as the one just described. The sheets in the binder will then be
unlocked and may be removed. If the sheets have closed holes they will be
slipped off the post or posts, the sleeves or sleeve having been first entirely removed
from the post or posts. If also the strip 2 is employed, of course it must be also
slipped off the posts before such sheets can be removed. If the sheets have
recesses or open holes the sheets may be pulled off the posts transverse thereto
without entirely removing the sleeve or sleeves or the strip 2. In locking the
binder the operation is reversed, as will be readily understood. It will be noted
that when the threads of a sleeve have become engaged with the threads of its
post, as when the sleeve has entered its cupped seat, the sleeve may be screwed
down so as to squeeze the sheets in the binder together with great force.
In Fig. 7 is shown a filling strip 21, which may be used if desired, adapted to
be placed over the strip 2 and having apertures 22 designed to receive the sleeves 9
so that the sleeves are almost covered by the strip 21. If preferred, the advantage
of the strip 21 may be secured by making the strip 2 about as thick as the two
strips 2 and 21 together, and forming recesses above the cupped seats 15 in the
strip 2, to correspond with the apertures 22 of the strip 21, as will be readily
understood. The cupped seats 15 and 20, it will be seen, are arranged to slide
freely along the posts on which the sleeves work, so that the sleeves may be
quickly locked on their posts at any point thereof by means of the cupped seats.
In this way the cupped seats and sleeves work efficiently together whatever may
be the number of sheets in the binder. The operation of the cupped seat is
effectively accomplished whether the cupped seat is inseparable from the strip 2,
as in Figs. 2 and 5, or is separable therefrom, as in Figs. 4 and 6. In both cases
the freely moving cupped seat operates to hold the threaded faces of the sleeve
contracted to the post. The sleeves and their cupped seat are shown as having
their meeting faces tapered. This is the preferred but not essential form.
It is to be understood that my invention is not confined to the embodiments
herein shown and specifically described, as the invention is susceptible of various
other embodiments, such as will occur to any one skilled in the art.
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. The combination, for a binder, of a binding strip provided with a fixed

page_text: threaded post, an internally threaded sleeve movable on said post and split so as
to be capable of expanding and contracting so as to unmesh and mesh with the
threads on the post, whereby when the sleeve is contracted its threads mesh with
the threads on the post and when expanded it may be slipped freely along said
post, and a cupped seat sliding freely on said post for holding the sleeve con-
tracted on the post.
2. The combination, for a binder, of a binding strip provided with a fixed
threaded post, an internally threaded sleeve movable on said post and split so as
to be capable of expanding and contracting so as to unmesh and mesh with the
threads on the post, whereby when the sleeve is contracted its threads mesh with
the threads on the post and when expanded it may be slipped freely along said
post, and a binding strip apertured to receive the post and having a cupped seat
for holding the sleeve contracted on the post.
3. The combination, for a binder, of a binding strip provided with two or more
fixed posts at least one of which is threaded, an internally threaded sleeve movable
on a threaded post and split so as to be capable of expanding and contracting so as
to unmesh and mesh with the threads on the post, whereby when the sleeve is
contracted its threads mesh with the threads on the threaded post and when
expanded it may be slipped freely along said threaded post, and a cupped seat
sliding freely on said post for holding the sleeve contracted on the post.
4. The combination, for a binder, of a binding strip provided with two or more
fixed posts at least one of which is threaded, an internally threaded sleeve movable
on a threaded post and split so as to be capable of expanding and contracting so
as to unmesh and mesh with the threads on the post, whereby when the sleeve is
contracted its threads mesh with the threads on the threaded posts and when
expanded it may be slipped freely along said threaded posts, and a binding strip
apertured to receive the posts and having a cupped seat for holding the sleeve
contracted on the posts.
