We WILLIAM BURROWS the younger of N° 40 High Pavement Nottingham in
the County of Nottingham Stationer and GEORGE TUCKER of N° 466 Coventry
Road Birmingham in the County of Warwick Manufacturer do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN BINDERS FOR BINDING LETTERS
AND PERIODICALS AND FOR OTHER LIKE PURPOSES " to be as follows:-
Our invention consists in constructing and combining in the manner hereinafter
described the parts of binders for binding letters and periodicals and for other like
purposes whereby great simplicity in the construction of the said binders together
with efficiency of action are obtained,
In constructing a binder according to our invention we take as a foundation a
casing such as is used for the ordinary binding of books the said casing consisting
of two flaps or covers somewhat larger than the leaves of the book to be bound
hinged to a middle piece of a size equal to the back of the book. To this middle
piece we fix a strip of sheet metal (tinplate for example) extending over the whole
of the inner side of the said back. The longitudinal edges of this strip are turned
inwards so that a strip of similar length and nearly equal in breadth can be
connected to or disconnected from the said back by a sliding motion. This latter
movable strip we will call the slide.
From thin sheet steel we make a corrugated plate preferably equal in length to
the slide and of a width after it has been corrugated nearly equal to the width of
the slide. This corrugated plate is fixed to the slide by rivetting or otherwise.
The corrugations of the said plate are flat at top and bottom and the sides of the
corrugations are so inclined to each other that the troughs made by two adjacent
corrugations are narrower at top than at bottom and the sides nearly touch at top.
The corrugations may be about half an inch deep but we do not limit ourselves to
any particular proportions..
We take other strips of flexible thin sheet metal preferably brass of a length
about equal to the length of the slide and of about an inch in breadth. We fold
these strips longitudinally so as to form light clips of the same shape as the

page_text: troughs in the corrugated plate and slightly smaller. The sheets to be bound are
inserted in these light clips and the said clips are introduced into the troughs of
the corrugated plate fixed to the slide and the slide attached to the back by sliding
it under the turned in edges of the strip of sheet metal fixed to the inner side of
the binder.
The sheets are gripped by the edges of the light clips and the pressure of these
edges is increased when the clips are inserted in the troughs of the corrugated plate
so that the sheets are held firmly.
Where for any reason it is desired to permanently hold together any series of
sheets such for example as lace pattern sheets they may be fixed in the clips by
two or more light rivetted pins passed through the clips and the enclosed margins
of the sheets.
For a very simple binder we dispense with the clips and the slide. In this case
the corrugated plate is fixed to the metal strip on the inside of the back of the
binder and the sheets to be bound are introduced by a sliding motion directly
into the troughs of the corrugated plate instead of being first introduced into the
light clins

We WILLIAM BURROWS the younger of No 40 High Pavement Nottingham in
the County of Nottingham Stationer and GEORGE TUCKER of N° 466 Coventry
Road Birmingham in the County of Warwick Manufacturer do hereby declare the
nature of the said Invention and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
Our invention consists in constructing and combining in the manner hereinafter
described the parts of binders for binding letters and periodicals and for other like
purposes whereby great simplicity in the construction of the said binders together
with efficiency of action are obtained.
In constructing a binder according to our invention we take as a foundation a
casing such as is used for the ordinary binding of books the said casing consisting
of two flaps or covers somewhat larger than the leaves of the book to be bound
hinged to a middle piece of a size equal to the back of the book. To this middle
piece we fix a strip of sheet metal (tinplate for example) extending over the whole
of the inner side of the said back. The longitudinal edges of this strip are turned
inwards so that a strip of similar length and nearly equal in breadth can be
connected to or disconnected from the said back by a sliding motion. This latter
movable strip we call the slide.
From thin sheet steel we make a corrugated plate preferably equal in length to
the slide and of a width after it has been corrugated nearly equal to the width of
the slide. This corrugated plate is fixed to the slide by rivetting or otherwise.
The corrugations of the said plate are flat at top and bottom and the sides of the
corrugations are so inclined to each other that the troughs made by two adjacent
corrugations are narrower at top than at bottom and the sides nearly touch at top.
The corrugations may be about half an inch deep but we do not limit ourselves to
any particular proportions.
"
We take other strips of flexible thin sheet metal preferably brass of a length
about equal to the length of the slide and of about an inch in breadth. We fold
these strips longitudinally so as to form light clips of the same shape as the troughs
in the corrugated plate and slightly smaller. The sheets to be bound are inserted
in these light clips and the said clips are introduced into the troughs of the corru-
gated plate fixed to the slide and the slide attached to the back by sliding it under
the turned, in edges of the strip of sheet metal fixed to the inner side of the.
binder.
The sheets are gripped by the edges of the light clips and the pressure of these
edges is increased when the clips are inserted in the troughs of the corrugated plate
Bo that the sheets are held firmly.
For a very simple binder we dispense with the clips and the slide. In this case
the corrugated plate is fixed to the metal strip on the inside of the back of the
binder and the sheets to be bound are introduced by a sliding motion directly into

light clips.

The same letters of reference indicate the same parts in the several Figures of
the Drawing.
The foundation or casing of the binder consists of two flaps or covers a, b and a
middle piece or back c`similar to the binding of a book. To the middle piece c of
the casing the binder proper marked d is connected the said binder d-being shown
separately in Figures 4 and 5. The binder d consists of a corrugated plate of thin
sheet steel or other elastic metal or alloy bent of the figure represented in the
Drawing. That is to say the corrugations are flat at top and bottom and the sides
are inclined to each other so that the troughs made by two adjacent corrugations
are narrower at top than at bottom and the sides nearly touch each other at top.
The trough shaped corrugations constitute a series of elastic binders between which
the clips holding the sheets or papers are gripped or between which corrugations
the sheets or papers to be held are directly gripped.

The corrugated bent plate or binder d is secured to a metal back plate or slide e
the longitudinal edges of the said back plate or slide e being bent over the longi-
tudinal edges or ends of the elastic binder d. The combined elastic binder d and
back plate or slide e is secured to the middle piece c of the flaps or covers a, b by
the flexible pieces f,f glued or cemented or otherwise fixed to the ends of the
binder and to the flaps or covers a, b. Or a strip of metal of the kind represented
in Figure 9 and marked g having longitudinal trough edges g³, g³ may be fixed to
the back or middle piece c of the binding.
Into this trough shaped back g, g the back plate or slide e carrying the elastic
binder d may be inserted by a sliding motion and when in its place fixed to the
trough back g, g³ by rivetting or otherwise. But we wish it to be understood
that we do not limit ourselves to any particular means for connecting the
corrugated plate or elastic binder d, d to the back or middle piece c of the book.
h, h are the clips in which the leaves sheets or papers i to be held in the binder
are gripped. Each of these clips consists of a folded or doubled piece of thin sheet
metal the said clip having the same sectional figure as the corrugations in the
elastic binder d (see Figures 6 and 7). The sheets to be bound are inserted in
the light metallic clips h and the said clips are introduced into the troughs of
the corrugated plate or elastic binder d in the manner represented in Figures 2
and 3. As the clips are introduced into the troughs of the corrugated plate or
binder & the narrow ends of the said troughs are expanded and by their elasticity
hold the clips firmly in the binder.
When a trough shaped back g, 9' Figures 8 and 9 is fixed to the middle piece c
of the binding the clips h, h carrying the sheets may be first introduced into the
troughs of the corrugated plate or binder d and the slide e of the latter inserted by
& sliding motion into the fixed back plate g, g² of the middle piece c of the binding
and fixed by rivetting or otherwise. But generally we prefer to use a binder of
the kind represented in Figure 4 and fix it to the middle piece c. of the binding by
flexible strips as before described.
Where for any reason it is desired to permanently hold together any series of
sheets such for example as lace pattern sheets they may be fixed in the clips by
two or more light rivetted pins passed through the clips and the enclosed margins 5
of the sheets,

or sheets the papers or sheets to be bound together may be inserted directly in the
troughs of the binder, d.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is to be performed we declare that
we claim
Constructing binders for binding letters and periodicals and for other like
purposes essentially of a corrugated plate of thin sheet steel or other elastic metal
or alloy the corrugations being flat at top and bottom and having inclined sides so
that the troughs made by two adjacent corrugations are narrower at top than
bottom the sides of the corrugations nearly touching each other at top the said
corrugated plate or elastic binder being secured to the middle piece of the casing or
binding substantially as hereinbefore described and illustrated in the accompanying
Drawing whether the sheets leaves or papers to be bound together be inserted in
light elastic clips before being placed in the troughs of the elastic binder or the
sheets leaves or papers be inserted directly in the troughs of the elastic binder.
