l'ontypridd 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 certain improved protectors for books, particularly
account books such as ledgers, journals, invoice books and the like, and the feature
of the invention lies in the peculiar formation of protectors constructed of flexible
יDJ

page_text: material so as to embrace the edges of the book and back of same. All of this will
be fully described hereinafter and finally embodied in the claim.
In the drawing:
Figure 1, represents a perspective view of a book equipped with my improvements,
the book being shown open.
Figure 2, a detailed section taken through the end of the back showing the device
for protecting said end.
Figure 3, a similar section taken through the edge of one of the covers showing
the device for application thereto.
Figure 4, a section showing in detail the construction of the protector for
application to the middle of the back of the book.
Figure 5, a view showing the construction of the protectors for the edges of the
sides of the book.
Figure 6, a detail in perspective of the protector for. the ends of the back of the
book, showing the said protector standing alone.
Figure 7, a sectional view showing the construction of the protectors for the edges
of the sides of the book.
The reference, numbered 1, indicates the sides of the book cover, and 2 the back
thereof, all of which are of the usual construction and do not require any detailed
description. The back 2 is of that class of back which springs outwardly as the book
is opened, that which is known as a spring back, and it is to this class of book
that portions of my invention are particularly applicable, though with slight
variations it may be used on others. The protectors for the ends of the back 2
consist each of a piece of rubber, or of any other flexible material, lined inwardly,
and, when necessary, outwardly, with linen or other suitable material, moulded
into a curved form, so as to comprise the lip 3 which is the inner lip, and the
lip 4 which is the outer lip the said lips being joined to each other at the outer
edges by the portion 5, so that a space will be left between the inner sides of the
two. Formed as a continuation of the portion 5 is the flange 6, which extends
throughout the length of the said portion. One of these devices is provided for
each end of back 2 as may be seen by reference to Figure 1 of the drawing.
The lip 3 is much thinner than its companion, the outer lip 4 and is wider, such lip
being adapted to extend between the spring back 2 and the inner edges of the
leaves comprising the book, while the flange 6 projects inwardly and is designed to
embrace the projected portion 7, caused by the end of the binding which is secured
to the inner edges of the leaves of the book.
The outer lip 4 is adapted to lie on the outside of the back 2 and closely against
the same, the said lip being much thicker than the lip 3 and being formed with an
inclined portion 8 marking the difference between the thickened portion of said lip
and the thin edge thereof, all of which will be fully understood. To secure this
portion of my invention in its place, the complete book is opened and the adjacent
sides of the lips 3 & 4 covered with a suitable glue, paste or cement. The protector
is now inserted in place so that the lips 3 & 4 will embrace the back, and when
necessary, part of the cover, after which the book is closed. The closing of the book
presses the protector into proper position and holds it so until the glue or paste sets
hard. It will be understood that two of these protectors will be provided for each
book and secured one to each of the respective ends of the spring back. The flange 6
fully protects the projected portion 7: of the binding while the part 5 of the
lips 3 & 4 embraces the respective ends of the back, but in case of very large books
the joint and part of the cover also, forming a protection for them. 9 indicates the
protectors for the sides 1 of the cover. These consist of. soft or hard rubber, or any
other flexible material, lined inwardly and when necessary outwardly with linen or
other suitable material, moulded into strips comprising the inner lips 10 and
outerlips 11 joined by the ribbed connection 12. The inner lip 10 is made of a width
equal to about one-half the width of the lip 11 while the connecting portion 12
extends along the outer ends of the portions or lips 11 so as to form in their devices

page_text: a round or square corner alapted to receive and embrace the round or square corner
of the cover which has to be protected.
One of these devices is provided for each end of the sides, and are of such a length
that they will extend the entire width of the sides. They are secured in place by
glueing or pasting or pasting and lacing with vellum strips as is common in the
art of bookbinding.
Figure 5 shows the manner of constructing the side protectors. It will be seen
that the device is formed with a corner at each end so that it may be cut in the
middle, thereby forming two protectors from one original piece. By these means
the protectors may be adjusted to suit the size of the cover as will be understood.
It is also possible and so intended, to cut down the back protectors to the requisite
size when necessary.
The protector for the middle of the back 2 consists of a strip of linen-lined rubber 13
having moulded therein a paste board block 14 or other device for forming a
projected portion on the strip 13. Its purpose is to protect the middle portion of the
back in a manner similar to the protection afforded by the end protectors.
The strip 13 is cemented to the back after the manner described in connection with
the other protectors as is common in the art of bookbinding.
By the use of my improvements books may be protected from the wear to which
they are necessarily subjected and their lives thereby prolonged. The protectors can
with equal facility be attached to old books as well as new.
When it is necessary to place a pocket on the inside of either of the covers of a
book for the purpose of placing therein an index, or for any other purpose, the inner
lips 10, Fig. 3, of the protectors are made of sufficient length to more than meet
each other and, are, either sewn together or cemented by slightly laping one over
the other, or one lip may be made of sufficient length to reach across the cover
and be cemented to the other lip. One of the side ends of the lip is now turned
over and attached to the cover forming a pocket.
When the side end of the lip is attached to the front of the cover the other
end is unprotected by any flap for the reason that when the book is closed the
back prevents anything from falling out, but when the lip is attached near the
back of the book a flap is then necessary to prevent anything from falling out
when the book is closed. A flap is made in the usual manner as is common in
the art of book binding.
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. A book protector consisting of lips of flexible material comprising 2 lips adapted
to lie one on each side of the part protected and to be secured thereon by cementing
direct to the said part.
2. A protector for each end of the backs of books and consisting of a piece of
flexible inaterial formed into a curved shape and having two lips adapted to lie one
on each side of said back and to embrace the end thereof, the protector having formed
thereon and at the outer end of the inner lip an inwardly projecting flange adapted
to embrace the projected portion of the binding at the inner edges of the leaves of
the book, the protector being constructed so as to be secured in place by cementing
direct to the end portion of the book back.
3. A protector for the ends of the sides of book covers and consisting of flexible
material shaped to comprise two lips adapted to lie one on each side of the part
protected and to embrace the edges of the same one end of the strip being provided
with a web-like portion connecting the ends of the lips whereby a corner is formed
for the reception of the corresponding covers of the side of the cover, the protectors
having forined on its exposed edge a rib adapted to receive the wear attending the
use of the book.
4. An improved article of manufacture, a protector for the edges of book covers
moulded from a combination of rubber and linen or like flexible material, and

page_text: comprising an inner and outer lip, the inner lip being thinner than the outer lip
which may extend one inch or across the inside of cover joining both ends and
forming a pocket for an index or miscellaneous papers, or may be cemented to the
cover.
