' 21:5 ATTORNEY Patented Nov. 15, 1932 UNITED STATES PATENT ol-"rlcs WILLIAM E. WARNER, JR, OF ROCHESTER, NEW YORK, ASSIGNOR T HENRY GONOLLY COMPANY, mo, OF ROCHESTER, NEW YORK, A coRPoRArIoNoE NEW YORK LOOSE LEAF BINDER Application filed March 21, 1929. Serial No. 348,909.

The present invention relates to loose leaf binders and an object thereof is a strong and durable structure. Another object of the invention is to improve that type of loose leaf binder in which supporting strips for the binding members are hinged to a back piece and covers, so that strong and durable hinged connections between the parts are ob tained. Another object of the invention is to provide for protecting the binder and the surfaces on which the binder is supported.

To these and other ends, the invention con sists of certain parts and combinations of parts, all of which Will be hereinafter described: the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a perspective View of a loose leaf binder with the binder members separated;

Fig. 2 is a fragmentary plan view of the binder in open position with the binder members separated;

Fig. 3 is a transverse section on the line 33, Fig. 2;

Fig. 4 shows the binder with the binder members connected;

Fig. 5 is an enlarged section on the line 5- 5, Fig. 2; and

Fig. 6 is an enlarged segmental perspec- 0 tive view of the end of one of the fiber protecting strips.

In the illustrated embodiment of the invention, 1 indicates a back piece made of sheet metal and having hinged at opp0- sides thereof, two binder supporting strips 2, the pintles 3 of the hinges being removable and the hinge being projected on the inner face ofth'e back'so as to provide right angled corners between the back and the strip. The binder-supporting strips are made of sheet-metal and are connected with metal cover-attaching strips 4 by hinges which have their pint-les 5 removable and which are projected from the outer face of the binder. The covers 6 are riveted at 7 to the attaching strips 4.

The binding means comprises, in this instance, a binding member in the form of a bar or strip 8 secured by removable screws 9 fiat against one of the supporting strips 2.

From the bar or strip 8 extends impaling pins or projections 10, some of which are longer than the others and are provided with shoulders 10 The other binding member comprises a casing 11 in the form of a channeled strip secured to the other'strip 2 detachably by screws 12 and havin openings 13 therein for the longer pins. rranged within the casing is a spring-pressed locking bar 14 which engageswiththe shoulders 10 and holds the two binding members together as is Well known in this art. A transfer member comprising a strip 15 with laterally extending impaling projections 16 on one side and short shouldered projections 17 on the opposite sides is adapted to pass through open.-

ings in leaves which are arranged on theimpaling projections 16. The projections '17 ,are adapted to 'securethe transfer member to the binder casing 11 through the locking bar 14.

With the end in view of protecting the binder, two fiber strips 19 are provided which are secured by the screws 9 and 12 to the outer faces of the strips2 projecting beyond .op-

posite ends of such-strips 2 and also beyond those sides of such strips next to, the back member 1. The edges ofthe strips 19 adjacent the cover attaching plates 4 are beveled at'20 to permit the covers to -swing to open positions and the hinges between the strips I 4 and the cover attaching strips lie between the edges of the cover and thefiber strips 19; It is preferred to cover the fiber strips so that the surface on which the binder rests willnot be scratched by the fiber strips. To this end, covering strips 21 are passed about the strips '19, the meeting edges of the coverings lying between the strips 2 and the strips 19. These coverings do not extend to the ends of the strips, so that in order to protect the free edges of coverings, the strips 19 are grooved or recessed in spaced relation to each of their ends, as at 22, so that the free ends of the coverings will lie adjacent the vertical wall of the groove 22 and be below the faces of the strips 19. Through this means, when the binder rests in an open position on a flat S111? face, the coverings 21' engage the surface, whereas, the fiber strip endsare spaced from the surface but when the book stands on an end, the exposed ends of the fiber strips engage the surface so that the coverings 21 do not become worn.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a loose leaf binder, the combination with a metallic back piece, metallic supporting strips for the binding means hinged to the back piece, covers hinged to said supporting strips, protecting strips secured to the outer faces of the supporting strips, and a covering for said protecting strips, the ends of the coverings being spaced from the ends of the protecting strips to expose such ends.

2. In a loose leaf binder, the combination with a metallic back piece, metallic supporting strips for the binding means hinged to 7 the back piece,covers hinged to said supporting strips, protecting strips secured to the outer faces of the supporting strips, and a covering for said protecting strips, the ends of the coverings being spaced from the ends of the protecting strips to expose such ends, and the protective strips being recessed adjacent their exposed ends to receive the ends of the coverings.

3. In a loose leaf binder, the combination with a metallic back piece, metallic supporting strips for the binding means hinged to the back piece, binding means supported by and connecting said strips, and covers hinged to said supporting strips, of an individual non-metallic protecting strip for each supporting strip secured to the outer face of each supporting strip and, when the two supporting strips lie in the same plane, holding the hinges out of contact with the surface on which the binder lies, and when the covers are moved into folded position the nonmetallic protecting strips extending in parallelism with each other and in alignment with the respective covers and extending belowthe back plate to support said hinges above the surface on which the'folded binder is supported.

4:. In a loose leaf binder, the combination with a metallic back piece, metallic supporting strips for the'binding means, hinged to the back piece, binding means supported by non-metallic material and secured to the outer face of the supporting strip, the ends of the protecting strip projecting beyond the ends of the supporting strip, and beyond that side of said supporting strip hinged to the back piece. a

6. In a loose leaf binder, the combination with a back piece, metallic supporting strips for the binding means hinged to the back piece, covers hinged to the supporting strips, binding means supported onthe supporting strips, of a non-metallic protecting strip arranged on the outer face of each supporting strip, and securing means common to the binding means and to the protecting strips for securing said binding means and said protecting strips to the supporting strips.
