BOOK COVER.-

Applcaton led July 28,

To all whom t may concern:

Be it known that I, JOHN SG1-IADE, a cit izen of the United States, residing at the city of Holyoke, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Book Covers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to book covers, but more particularly has reference to articles of this description known as ring binders.

The particular1 object of the invention is to provide an exceedingly durable cover of this description, and furthermore, an exceedingly economical one in that the cutting of leather or other expensive material is effected with great saving.

In the accompanying` drawing- Figure 1 is a plan view of the inside of the cover with the side covers opened out.

Figure 2 is a detail sectioned perspective of the metal back plate.

Figure 3 is a section at the line 3-3 of Figure l.

Figure l is a section at the line 4:-4 of Figure l, and

Figure 5 a detail broken perspective of the metal linger strip with the alined eyes partially formed and the extremities in position to be clenched to the cover portions.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 is a metal back plate, preferably concavoconvex in cross section and having extending integrally from its side edges spaced fingers 2 which are bent and formed into spaced alined projecting eyes 3, the extremities of the lingers after forming the eyes being snugly contacted with the inner face of the plate.

l are cover portions that are preferably made of leather but which may be made of any suitable flexible penetrable material,

1923. Serial No. 654,300.

and at the inner edges of the covers are secured spaced alined and projecting eyes 5, which eyes are formed from an elongated metal strip 6 having extending from opposite sides spaced and staggered fingers 7, 8, one series of these fingers being clenched into one face of the covers, while the other fingers are first formed into the eyes 5 and then have their extremities clenched into the other face of the cover.

The eye portions at the side edges of the metal back 1 and at the inner edges of the covers, are then interengaged and pintles 9 ,inserted through the eyes, thus completing the hinging of the covers to the back plate.

The ring carrying structure (not shown) is secured in position in the usual manner by means of the eyelets (only one shown) 10 that rise upwardly from the plate 1, the outer face of this plate being countersunk at 11 to accommodate the heads of the eyelets.

A book cover of this description is exceedingly attractive and presents a contrast between the bright metal back and the flexible covers, and such cover is exceedingly durable and economical.

No claim is made to the metal strip that is attached to the covers since this strip merely affords a very convenient form of eyes to cooperate with the eyes at the side edges of the metal back.

What is claimed is A book cover of the character described, comprising a metal back plate having integral with its side edges a series of spaced alined projecting eyes, flexible covers having along their inner edges alined spaced eyes that have extremities that are clenched to the inner and outer faces of said. covers, said eyes being interengaged and pintles inserted through said eyes.

In testimony whereof I aliix my signature hereto.

JOHN SCHADE.
