This invention relates to book. hacks for loose leaf bookssbut is particularly identified with devices of this description vwhich employ arch-shaped prongs that are carried by leaves pivotally connectedalongtheir inner edges and confined as to the. outer edges within a spring plate, these prongs being complementary parts of ringswhich'latter are formed when the prongs are in closed condition. w
-A construction-likethat above descrlbed is I known as a loose leaf ring binder, and the present invention'has nothing Whatever to do with the actual loose lea'fstructure and it is therefore immaterial whether the prongcarrying leaves areconfined within: a top spring plate or a bottom spring plate.
"This application isa continuation in. part of application Serial No;181 ,6 l1 filed April 7, 1927.
' The mainobjectofthe invention is to provide "a non-metallic book back, suitably shaped in cross-section and of. a length and width generally corresponding to thelength and width'of thebook, and inade'from a suitably shaped pressed or molded material such asvulcanite,papier-inach,bakelite,celluloid,
vulcanized fiber, or other suitable analogous non-metallic material, and the latter is colored and patterned to correspond with the coloring and pattern-desired, the book back carryingdevices which extend from its inner face and'are secured to one of the plates of the looseleaf structure.
the book back itself with fastening devices extending from its inner face. a Figure 3, is a sectional; the line 3-3 of Figure 1. I 1

In Figure 3, the plates 3 are confined within the top vplate, but such plates are frequently'confinedwithin pockets (1 in the bottom plate, as shown at Figure 4, and the structure ofthe binder in this respect is immaterial sofar as the application of theback is concerned, and in either instance, the back may be secured by'long eyelets 7 to the top plate as shown at Figure 3, or by short eyelets 9'through perforations in the bottom plate, as's'hown at Figure 4, and rivets may beem'ployed' inboth instances, if desired;

Therefore, the manner of lets or rivets to the plates so as to bind the back in position is immaterial,and also it is within the scope of this inventon'to employ and means for securing said devices to the loose leaf structure.

A loose leaf book consisting of a loose leaf holding structure that comprises top and bottom plates, separable prongs, resiliently acting members carrying said prongs and housed within-one ofsaid plates, and a separate rigid back made'of a non-metallic imaterial suitably shaped in'cross-section and of a length andfwidth generally correspond- 'ing to the l'engtliand width'of the book, said 'back carrying, fastening devices and one of said plates having perforations through which latter ,said devices are passed and clinched whereby said back is secured as an unit to said book.
