Improvements in or connected with Securing the Leaves of Books
or Shop Heads within Covers.
I, WILLIAM LOVEL BONNETT, of 41 Cheapside in the City and County of
London, Wholesale Stationer, do hereby declare the nature of this invention to be
as follows:-
66
My present invention refers to improvements in securing the leaves of books or
shop-heads" within the covers of same, and the object of my invention is to so
construct or arrange the fixing devices, as hereafter described, that the said leaves
or shop-heads may be readily inserted and securely held within the cover 'and' may
be removed therefrom with equal facility when so desired.
According to my invention I fit to the inside back edge of one of the boards or
covers, a metal slide adapted to grip the back edge of the shop-heads 'or the like.
This slide, which may be of sheet metal, I form with a base part to be secured to
or inserted in the cover as aforesaid; from this base part a back rises perpendicular
to the said base part; and at the upper edge thereof there is an upper flange
parallel with the lower base part, the slide thus formed presenting a channel section.
The outward edge of the upper flange is returned inwards to form a catching edge
to the shop-heads, the returned flange being curved at its corner near the top part
of the book cover, while the slide near the bottom edge of the book cover is formed
or provided with a stop.
The leaves or shop-heads composing the books are laid upon each other and
secured by wire staples such as are well known and in common use, and such staples
may be inserted at several places along the back, say two, or the leaves may be
otherwise fastened together provided that the fastenings are such as will allow the
trough to grip the back edge or stump of the book.
To insert and fix the bound leaves, the latter are placed so as to cause the lower
edge of the "stump" to enter the top of the trough guide, and the book is then
slidden downwards, whereby the said stump becomes gripped by the return edge of
the slide, while the rounded corner of same permits the passage of the book to
within the slide to be effected with facility; and when the said book stump arrives
at the stop at the bottom of the slide, it is firmly held. In some cases the book
may be passed directly under the return edge and into the slide without being
slidden into same, the elasticity of the slide and of the return edge allowing
of such mode of placement.
The fixing of books or shop-heads within their covers according to my invention
is particularly adapted for the use of shop salesmen or women, but the same may be
employed if desired to secure other books or bound leaves.

page_text: Improvements in or connected with Securing the Leaves of Books
or Shop Heads within Covers.
I, WILLIAM LOVEL BONNETT, of 41 Cheapside, in the City and County of
London, Wholesale Stationer, 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 :-
My present invention relates to improvements in securing the leaves of books or
"shop-heads" within the covers of same, and the object of my invention is to so
construct or arrange the fixing devices, as hereafter described, that the said leaves
or shop-heads may be readily inserted and securely held within the cover and may
be removed therefrom with equal facility when so desired.
According to my invention I fit to the inside back edge of one of the boards or
covers, a metal slide adapted to grip the back edge of the shop-heads or the like.
This slide, which may be of sheet nietal, I form with a base part to be secured to
or inserted in the cover as aforesaid; from this base part a back rises perpendicular
to the said base part, and at the upper edge thereof there is an upper flange
parallel with the lower base part, the slide thus formed presenting a channel
section. The outward edge of the upper flange is returned inwards to form a
catching edge to the shop-heads, the returned flange being curved at its corner
near the top part of the book cover, while the slide near the bottom edge of the
book cover is formed or provided with a stop.
My invention will be readily understood by reference to the accompanying
drawing whereon
Figure is a plan view of a pair of covers having a fixing slide constructed
according to my invention fitted thereto,
Figure 2 is an end sectional view of the covers and slide shown at Figure 1, the
book or shop-heads being in position,
Figure 3 is a perspective view of the slide detached from the covers and shown
drawn to a larger scale than the previous figures;
Figure 4 is a perspective view to show perforations in the back of the slide as
hereafter mentioned, and
Figure 5 is a cross section of a slide on an enlarged scale.
Similar letters of reference indicate like parts in the several figures of the
drawing.
A, are the covers onto which the slide is affixed by its base part B, say for
example by rivets or the like, at B'; C is the back rising vertically from the edge
of the base part, and D is the upper horizontal flange. E is the catching edge
formed by bending round or returning the outer edge of the horizontal flange D.
This catching edge E is curved or narrowed at one end, marked E', as shown in
the plan view, Fig. and at the opposite end the slide is formed or provided with
a stop piece F as shown particularly at Figures 1 and 3. G represents the leaves
or shop heads.
The leaves or shop-heads G composing the books are laid upon each other and
secured by wire staples such as are well known and in common use and such staples
may be inserted at several places along the back, say two, or the leaves may be
otherwise fastened together provided that the fastenings are such as will allow
the catching edge E of the trough to grip the back edge or stump G' of the
book.
'
To insert and fix the bound leaves, the latter are placed so as to cause the lower
edge of the stump G¹ to enter the top of the trough guide, and the book is then
slidden downwards whereby the said stump becomes gripped by the return or
catching edge E of the slide, while the rounded corner E of same permits the
passage of the book to within the slide to be effected with facility; and when the

page_text: said book stump arrives at the stop F at the bottom of the slide, it is firmly held.
In some cases the book may be passed directly under the return edge and into the
slide laterally without being slidden into same, the elasticity of the slide and of
the return edge allowing of the top part D of the trough being sprung upwards,
and in some cases I may increase the elasticity of the trough by forming perforations
such as those marked H at Figure 4, in the back C of the slide. Fixing devices
such as described may be readily adapted to receive and grip any desired or
varying thickness of leaves or shop-heads by suitably springing upwards or
depressing the gripping flange.
Devices constructed according to my invention are particularly suitable for use
with shop-heads where sheets of carbonized paper are employed, as the gripping
trough retains the transfer paper in position and protects it from injury.
Although the fixing of books or shop-heads within their covers according to my
invention is particularly adapted for the use of shop salesmen or women, yet
the same may be readily employed if desired to secure other books or bound
leaves.
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. In securing the leaves of books or shop-heads within covers, the channel
section slide for receiving the back or stump of the book or shop-heads, said slide
having a catching or inwardly returned edge to grip the back of said leaves, or the
fastenings thereof, substantially as set forth.
2. In securing the leaves of books or shop-heads within covers, the fixing slide
composed of a base part B secured to the covers A, a back part C and upper
flange D, in combination with an inwardly returned catching edge E curved or
rounded at one end and adapted to grip the edge of the leaves or shop-heads, or
their fastenings, and a stop piece F to limit the sliding motion given to the leaves
or shop-heads when the same are inserted substantially as described and illustrated
with reference to the accompanying drawings.
3. The general arrangement and construction of devices composing my improve-
ments for, or in connection with, securing the leaves of books or shop-heads within
covers, all combined and operating substantially as hereinbefore described and
illustrated with reference to the accompanying drawings.
