Specification of Letters Patent.
Application filed October 6,1906. Serial No. 337,766.To all whom it nmay concern:
Be it known that I, REES F. PARRY, a citi-
zen of the United States, residing at Dallas,
in the county of Dallas and State of Texas,
5 have invented certain new and useful Im-
provements, in Loose-Leaf Binders, of which
the following is a specification.
This invention relates to loose-leaf bind-
ers such as are used for record, minute, jour-
io nal, or sales books and various other records.
My invention is especially adapted for use
in public offices in which records of deeds,
wills, court-minutes, &c., are kept subject to-
public inspection, also by corporations and
15 commercial and financial concerns.
The invention will be described in connec-
tion with the 'accompanying drawing, in
which-
Figure 1 is an end view of a book embody-
20 ing the invention opened at one side, so that
the front leaf or leaves may be removed.
Fig. 2 is asimilar view of the book opened at
the other side. Fig. 3 is a transverse section
of a portion of the book, taken through one of
25 the binding-posts. Fig. 4 is a longitudinal
section on the line 4 of Fig. 3. Fig. 5 i a
partial plan view illustrating the devices for
locking the covers in place. Fig. 6 is a view
similar to Fig. 4, but showing the opposite
3o end of the book. Fig. 7 illustrates one'
means for locking and unlocking the book.
Fig. 8 illustrates another means for locking
and unlocking the. book. Fig. 9 is a plan
view of a portion of one of the fly-leaves of
35 the book, and' Fig.. 10 is an end view of the
leaf shown in Fig. 9.
. Referring to the drawings, 11 12 indicate
the two covers of the book, which may be of
any desired material and construction, and
40 13. indicates the back.' Adjacent to the
hinge which connects each cover to the back
is a locking-slide 14, preferably contained in
a r etal casing 15 of ,rectangular..cross-sec-I
tion, which casing is suitably connected. to
45 the-binding. Each slide 14 is provided with
a plurality of perforations-16 and is normally
pressed against a stop 17 by a spring 18, in-'
terposed between the shoulder or seat 19 of
the slide 14 and an abutment 20 on the case
so 15. . The spring is inclosed within the casing,
and the slide 14 may be cut away, as shown,
to make room for it.
The openings 16 in the locking-slides regis-
ter with openings in the casings 15, and the
55 corresponding openings in the two casings are
opposite to each other when the book is IPateeteci March 1, 19.07.
closed. A plurality of independent or de-
tachable posts or rods 21 extend from cover
to cover adjacent to the back, each post be-
ing adapted to enter two opposite openings .6
in the casings 15 and to be automatically
locked to the covers by the slides '14. For
the purpose of connecting the' poets to the
slides the posts are provided with notches or
recesses 22 and preferably with beveled ends 65
23, which cause them to pass more readily
into the openings of the casings and the
slides.
As shown, the covers are provided with
flexible or hinge portions 24 just 'in front of 70
the casings 15, and the casings.are hinged at
their rear sides to the back of 'the book. 'The
casings are preferably connected by hinge-
joints 25 to the curved plates 26, which con-
form to the curvature of the back of the 75
book and are preferably -incased in the back
and form a part thereof. The casings may
be connected by a ,seriesof these back-plates
or by a single continuous back-plate extend-
ing throughout the entire length of the book &o
or the greater portion thereof. These back-
plates serve to stiffen the back of the book
and preserve its, shape and -.ao 'to hold the
casings 15 in proper relation to 'the hack and
to each other, and they are especially useful 5
in maintainingg the openings in the 1asigs
directly opposite each other,-so that-the 'posts
21 will'readily enter the casings.anc-the open-
ings in the locking - slides when 'the book is
closed. '9O
In the drawings, 27 indicates the leaves of
the book, and 28. a tab or marker, which is
connected to one of the leaves for a purpose
to be hereinafter explained. Just'within the
cover, on each 'side of the hook, I preferably 9
place a fly-leaf 29, which is hinged .at 30 to a
stiff strip 31. The -strips. 31 are preferably
reinforced by flat thin 'metal- plates 32.
Thus, as shown, the strips 31 are each coin-.
posed of a flat metal plate 32, surrounded by ioc.
a cover or case of leather or fabric, the edges
of which are connected to the fly-leaf proper,
29. Each of the strips 31 is'provided with a
series of openings 33, which receive the posts
21 -and cause them to register with the open- 1.5
ings in the casings 15. The posts 21 are
preferably round in -section and of substan-
tial diamete so as to be stiff' and strong,and
the perforations in the loose leaves .27 and
the strips 31 are also preferably round and xio
slightly larger than the posts.
