TEMPORARY BINDER 0R LOOSE-LEAF BOOK.

Specification of Letters Patent.

Patented Jan, 2%, 197.5.

Application filed January. 21, wi l. Serial No. 813,573.

1719 all 'erizom it may concern Be it known that I, REINHOLD Kauai-Mme, citizen of the United States, residing at Milwaukee, Wisconsin, have invented certain new and useful Improvementsin Temporary Binders or Loose-Leaf Books, of which the following is a specification.

This invention relates to improvements in temporary binders or loose leaf books.-

The main objects of this invention are: First. to provide a temporary binder or loose leaf book. of the ring type, which is very convenient in use and one in which the parts are simple and economical to produce and easily assembled. Second, to provide in a temporary binder of the class described, an improved rocking hook supporting plate structure. Third, to provide in a binder oi the class described, an improved hook or ring member structure.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention. is clearly defined and pointed out in the claims.

A. structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure l is a detail inside view of a structure embodying the features of myinvention, with the covers extended. l ig. ll is an enlarged detail longitudinal section on a line corresponding to line 2+2 of Fig. T, with the cover closed and with sheets shown in conventional form Fig. TH is a rearview of the hook {carrying plates or members removed from the back member. Fig. lV is a front perspective view of the back member with the hook carrying plates and hooks mounted thereon, the hooks being shown in their open position. Fig. V is a detail section on a line corresponding to line 5-5 of. Fig. l, the covers being omitted. l ig. Vl is a sectional view corresponding to that of Fig. V, with the hooks in their open position. Fig. Vll is a detail rear view showing the mounting of the cover member upon the back member. Fig. VTll: is a detail section on a linecorresponding to line 8'--8 of Fig. V, showing details of the hOOli' mounting on attachment to the hook carryliig. TX is similar section showing slightly modified construction, the

"hook securing members being folded on the inner side of the hook carrying plates instead of riveted 'or upset.

in the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawings, the structure illustrated is provided with the flexible covers 1. The hook carrying members 2 and 3 are mounted on the rigid or non-yielding back plate or member l. The covers are preferably secured on the back plate 4; by the cover member 5, which is provided with loops 6 struck in to engage the longitudinally disposed tongues '7 projecting from the edges of the openings 8 in the badlr member. See Figs. V, VI and Vii. The back member 4 is curved in cross section and thecover member is curved to embrace it, as shown in the drawing.

The loops 6 are formed by slitting the cover member transversely and striking in. a strap-like loop portion, as shown, so that by placing the cover members over the back members with the loops 6 in the openings and sliding the members longitudinally relative to each other, the tongues and. loops are engaged. This permits the assem bling of the parts carried by the back memher, and the covers upon the cover member,

and assembling these after they are otherwise substantially complete.

i The back member lis provided with in-' wardly turned flanges 9 at its edges, the outer edges of the hook carrying plates being disposed in the anglesformed by these flanges.

The hook carrying member 2 is provided with a rearwardly projecting flange 10 at its inner edge having longitudinal slots ll therein. in which the tongues 12 on the plate 3 are disposed. These slots are arranged close to the plate 2. The tongues 12 are ofifset inwardly at 13 and rearwardly inclined to permit the plates to lie edge to edge. This provides a rocking connection for the inner edges of the plates. Theplates being supported in the angles of the flanges 9 are free to rock, the upward rocking move ment being limited by the tongues 12 en gaging the under side of the opposed plate, u

see Fig. "VT.

Springs M, which are preferably bowed,

. 5 or edges of these springs engage the flange 10, the flange being provided with slots 15 for the tongues 16 of the springs. When the plates are rocked to the position shown in Fig. V or their closed position, these springs are placedunder tension, but owing to the fact that the plates are rocked past the center the springs cannot lift them. As soon as the plates are swung past the center the springs act to swing them to and retain them in the open position, as shown in Fig. VI.v

The plates are provided with finger pieces 24: at their. ends for convenience in swinging or manipulating them.

The hooks or ring members 17 are preferably formed. of sheet metal suitably curved to provide rounded surfaces and have integral base portions 18 with rivet extensions or tongues 19 at each side. These extensions are arranged through spaced rivet holes 20 in the plates and riveted therein, as shown in Fig. VIII.

In the modified construction in Fig. IX the rivetextensions 21 are longer than those shown in Fig. VIII and are folded over on the inner side of the plates instead of being riveted thereon. This forms a very rigid and secure method of'attaching the hooks or ring members to the plates, and one which is very economical, in that the parts are economical to produce and quickly and easily assembled.

The plates are' assembled with their tongues 12 engaging the slots 11, and the 40 tongues 16 of the springs engaging the slots 15 of the flanges 10, and the parts are then slipped longitudinally into the back member 4 and retained therein by turning up the ends 25 which are in the form of extensions on the ends of the back member. These ends 25 may, if desired, be soldered or brazed to the'ends of the back member, but that is not ordinarily necessary. One hook of each pair is provided with a V- shapednotch 22 and the other with an A- shaped tongue 23 fitting into the notch when the hooks are closed.

The notched and tongued hooks are arranged alternately so that a sheet can not work from the hooks as might be possible where the tongued and notched hooks are all similarly disposed so that the openings between come in alinement.

I have illustrated and described my invention in detail in a very satisfactory embodiment. I have not attempted to illustrate or describe the various modifications which I contemplate, as I believe the disclosure -made will enable those skilled in the art to which my invention relates to embody or adapt the same as conditions may require. I desire to be understood, however, as claiming my improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters- Patent is:
