Improvements in or relating to Binders for Periodicals, Papers, and
the like.
ERNEST AUGUSTE GEORGE STREET, of 60, Boulevard Haussmann, Paris, in the
Republic of France, Engineer, 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 an improved binder of the kind called "string binders
enabling periodicals pamphlets, journals etc. to be provisionally or temporally
classified and bound up as they are published and is characterised by the fact that
the thickness of the binder can be increased as the number of publications in-
creases, while otherwise its dimensions remain the same. This result is attained
by causing the back of the binder to slide in one of the covers, so that the
width of the back increases in accordance with the number of papers filed.
The new binder according to this invention is illustrated, by way of example,
in the accompanying drawings, in which
Fig. 1 shows the binder open in plan
Fig. 2 being a cross section of same.
Fig. 3 is a sectional view on a larger scale, showing constructive details of the
essential portion of the binder.
Fig. 4 shows a modified construction of the binder open.
Fig. 5 shows the same binder closed.
Figs. 6, 7 and 8 are detail views on a larger scale showing the essential portion.
of the binder.
The binder according to this invention consists chiefly of two parts.
1. A card board or other cover D³ to the edge of which is permanently secured
by any desired means by (glueing sewing etc.) the back A made preferably of soft
canvas and provided with strings through which are passed the publications to.
be filed.
2. A card board or other cover B¹ to which the back A is secured at a variable
distance according to the number of publications to be put on the file. This
cover B carries a card-board or other flap B secured by means of a strip of
canvas or the like forming a hinge. When this flap is folded down it hides the
portion of the back A which is not used.
The back A is provided at the top and bottom with any desired number of
eyelets a through which pass the strings destined to hold the papers. The movable
back is secured to the cover B₁ at the top and bottom by fasteners E which are
passed through a hole in the cover B¹ and through one of the eyelets of the
back A.
The operation of the binder is as follows:-
First when there is only one publication in the binder all the surface of the
back A except that portion of it which corresponds to the first string is placed
within the cover B₁ and the flap B is folded down and hides this unused portion
of the back. The fasteners E are then passed through the eyelet next to that

page_text: through which passes the string holding the paper. The binder can then be opened
like a book and the pages of the paper etc. in question can be turned over.
When a second paper etc. is to be inserted in the binder the fasteners securing
the back to the cover B are removed and a portion of the back A sufficient to
disengage a new string from under the flap B is withdrawn. from the cover B¹.
Then the flap B is again folded over the unused portion of the back and the
fasteners E placed in corresponding holes so as to secure the back A to the
cover B¹.
As the number of publications to be placed in the binder grows the same
operation is repeated and it will be clear that the thickness of the binder can
increase indefinitely its dimensions otherwise remaining the same.
Figs. 4 to 8 show a modification of the construction just described. Instead of
having on the cover B¹ a flap B pivoted about a hinge bb (Figs. 1 and 2) the
cover B may be made hollow so that the back A slides within it. The hollow
cover will then be provided, as the cover B¹ in the preceding construction, with
holes C enabling fasteners or small pins e on springs e¹ secured at e² and provided
with projections es to be introduced so that said pins e can be readily withdrawn
from the holes C or introduced therein.
It will be clear that instead of making the back B' hollow throughout the whole
of its depth it may be simply provided with a pocket of sufficient depth to receive
all the unutilised portion of the back.
Fig. 6 illustrates the manner of putting in the papers. They are simply passed
between the strings and the back and folded round the former, as is usually done
in all the ordinary string binders.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A binder for periodicals papers and the like comprising two covers one of
which is secured to a back of soft canvas or other material provided with a series
of eyelets along its upper sleeve edges through which eyelets pass the cords for
holding the papers in place, the other cover being provided on its inner surface
with a flap of suitable material hinged to the cover, said flap being destined when
folded down on the cover to cover the non-utilised portion of the back the movable
cover and back being secured in desired relative position by means of fasteners or
pins passing through the eyelets in the back and through holes in the cover
coinciding with the eyelets of the back.
2. In a binder of the character described the substitution for the flap secured to
one of the covers of a pocket extending if desired only to a certain portion of
the depth of the cover or throughout the whole of said depth substantially as
described.
3. The combination and arrangement of parts constituting the complete binder
for periodicals papers and the like substantially as described or illustrated in
Figures 1 and 2 or in Figures 4, 5, 7, and 8 of the accompanying drawings.
