' To all whom it may concern: 1 Be it known that I, BY BERTRAM CROW- ELL, a subject of the ing of Great Britain, and resident of the city of Toronto,
, county of York, Province of Ol'itario, in the 5 have invented certain. ,new and useful Improvements (in Book Covers, described in the following specifi-' Dominion of Canada,
cation and illustrated in the accompanying drawings,- that form part of the same.
The principal object of this invention is to devise a book cover particularly adapted for ring binder type ofloose leaf books which will be practically indestructible and will 1 5 retainits shape indefinitely. p v
The principal feature of the invention consists material and reducingcthe cross sectionalarea at the hinge portions. l f.
In thedrawings Figure 1 is a sectional view of with this invention, showing a nut embedded to ,receivethei screwsv for holding the metal It has been the usual custom to manufacture book covers of theming binder type of leather or flexible'fabrics but these-are extremely expensive and wear out? very quickly. The present invention contemplates the use of a rubber material of sulficient hardness and thickness to form an effective protection .to the leaves of the book and of a desired flexibilit In the form'of in liigurel thecovers 1 are sheet of rubber material integrally cpnnected with the back 2, the material being reduced in thickness at the point ofconnection between theycovers andthe back. This reduced portion 3 is sufliciently thin'to .be of a flexibility to allow the cover to be} turned,
back quite readily, the thin portion formon moulding the cover of a rubber" a cover constructed inaccordanee.
showing the structure with reinforced hinge main portions the invention illustrated formed of a ing a very flexible hinge The back portion 2 is preferably thicker than the covers. 1 and where used for the ring binder type of cover hassuitable fastening nuts 4 moulded therein.
In making the covers the sheet rubber material is placed upon a. mould face 5 and the upper section of the mould is provided with ribs t; and an intervening transverse hollow portion 7 j which, when pressure is applied, forms. the rubber material into the back 2 and hinges 3. The nuts 4 are moulded into place i'nthe moulding of the cover.
It niay be found desirable in certain forms of covers .to reinforce the hinges and in Figure ment 8 of textile fabric molded into the back 2 and extending through the hinge portions 3into thecovers 1,. y l 1 The invention is herein shown applied to the ring ty'pe; of binder butof course it will e other forms of books. 8 I f What I claim as my invention .1s:- 7
"2. A book cover formed of flexible rubber 7 material having narrow parallel strips of rcduc'ed thicknessexteiiding thereacross forming flexible hinges, the portion between said hinges being of greater thickness than the and forming a back, and means moulded in said back for securing the leaf binder.
3. A book cover, comprising, a body of flexible rubber material moulded to shape with thin strips connecting the back portion with the cover, a reinforcing fabric embod ded the back and extending across the J thin strips, and means for securing the leave of the book moulded into the rubber material. l
