TEMPORARY BIN-DER.

Specification of Letters Patent.

Patented Jan. 8, 1907.

To all whom, it may concern:

Be it known that'I, WALTER S. MENDEN- HALL, a citizenof the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

My invention relates to a temporary leafholding book of the class employing loose leaves with marginal orifices and opening and closing retaining-hooks held Within the back of the book-cover.

The object of the invention is to provide a simple and efficient construction of these devices, and I preferably also employ a masterhook, the manipulation of which controls the series of hooks.

It is also preferable that the master-hook rovicled with interlocking surfaces which interlock against strains applied in the direction of hinged movement of the hook-sections, but which yield to lateral strains sufiiciently to be man ually unlocked for opening the hooks and to automatically interlock for closing the hooks.

Another object of my invention is to provide a simple casing or housing with convenient and secure means for attaching it to the book-cover.

These and other objects of my invention will be more fully set forth in the description of the accompanying drawin s, forming apart of this specification, in whic Figure 1 is a top plan view of the open cover. Fig. 2 is a top plan view of the hinges and hooks open. Fig. 3 is a top plan view of the bottom casing. Fig. 4 is a section on line a: as, Fig. 1, the hooks being shown in open position. Fig. 5 is a section on line 10 w, Fig.1.

1 represents the back of the book-cover.

2 represents the lower casing member fitti'rv snugly Within the cover-back (see Fig. 4) and provided at its up er opposite edges with the outwardly-exten ing flanges 3.

4 represents a support upwardly arched and bridging the space formed between the inner sides of the casing member 2. The medial portion of this support 4 is provided withthe longitudinal recess 5, which serves as a seatfor the hinged members of the device.

6 7 represent the hinge members, the meeting edges of which are provided with the alined eye-lugs 8, through which passes the lBLlIIgG-IOd 9, as indicated in dotted lines,

The hook-sections 10 11 12 are attached to l the hinged member 6, and their cooperating hook-sections 13 14 15, respectively, are attached to the member 7.

' The hook-sections 13 10 and 12 15 have at their meeting edges the V-notches 16, which anchor the meeting ends against lateral strains.

i The meeting ends of the hook-sections I 11 14 are provided with the interlocking surfaces 17, which automatically interlock when the ends are forced together and which can only be unlocked by applying the strain transversely to the line of their hinged movement. This hook, composed of the sections 11 14, is therefore a master-hook, the manipulation of which controls the opening and closing of the other hooks.

' The lower ends of the hooks are provided with lugs 18, which are secured to the. hinge members 6 7, as shown in Fig. 5. 'At one or more places along the meeting edges of the hinge members 6 7 the metal is cut away, as shown at 19, Fig. 2, to provide for the dispositionof the coil-springs 20. (See Fig. 2.) These coil-springs are coiled around the rod 9 withtheir opposite ends bearing down, respectively, on the up er faces of the hinges 6 7, thereby norma ly pressing the outer edges of the hinges in a downward direction, as shown in Fig.4, in which position the hinges rest upon the straight sloping sides of the sup ort 4 with the hooks open.

It 1 thus be seen that when the meeting ends of the master-hook 11 14 are disengaged the hinges will be pressed downwardly, opening all the hooks, as indicated in Figs. 2 and 4, and when the meeting ends of the m aster-hook are pressed together and interlocked the hinges will move upward on their hinge-rod 9 until they'lie against the cover late 21, as shown in Figs. 1 and 5, with all of the hooks closed- This cover-plate is provided with marginal notches 22, through which the hooks pass. It is also provided at its opposite edges with the downwardlyturned marginal hooks 23, which engage over the flanges 3 of the bottom casing 2. (See Figs. 4 and 5.) To securely attach this casing, composed of the members 2 and 21, to the cover-back 1, I provide the cover-lining 24, of any suitable material,..which is folded in between the meeting surfaces of the flanges 3 and the hooks 23, the opposite outer edges of this lining being glued to the cover 1. (See Figs. 4;, 5.)

Having described my invention, I claim 1. In combination with the cover-back of a looseleaf-holding book, a hinge-rod and hinge members movable independently of the bac a spring engaging the hinge members and pressing them normally in one direction of movement, cooperating hook-sections secured to the hinge members, one of said pairs of hooks having its meeting ends provided with interlocking surfaces, substantially as described. v

2. In combination with the cover-back of a loose-leaf-holding book, a hinge-rod, hinge members having alined eye-lugs through which the rod passes, a support for the hinge, a spring engaging the hinge members and holding them normally in one direction, and hook-sections attached to said hinge members, substantially as described.

3. In combination with the cover-back of a loose-leaf-holding book, a lower casing member fitting the back, an arch-support Within the casing, hinge members and a hinge-rod on said support, a spring forcing the hinge members in one direction normally, hook-sections attached to said hinge -1nembers, a cover-plate attached to the casing, and means for attaching the case to the cover-back, substantially as described.

4. In combination with the cover-backof a loose-leaf-holdin book, a" lower casing member fitting wit the back, an arched support having a medial, longitudinally-extending recess, hinge members having alined eye-lugs, a hinge-rod passing through said eyes, said lugs seating in the recess a spring exerting a normal pressure on the hinge, hook-sections attached to said hinge members, and a cover-plate for the lower casing,

the hinge members lyingagainst the oppo-, site sides of the sup ort when the hooks are open and against t e under, surface of the.

cover-plate whenthe hooks are closed, substantially as described.

5. In combination with the cover-back of a loose-leaf-holdingmbook, a lower casing member fitting Wit the back, an arched support having a medial longitudinally-extending recess, hinge members having alined eye-lugs, a hinge-rod passing through said eyes, said lugs seating in the recess, a coilspring around the rod the op osite ends of which bear on the hinge mem ers and press them normally down on opposite sides of the support, hook-sections attached to said hinge members, one of said hooks having interlocking 'meeting ends thereby constituting a master-hook, and a cover-plate attached to the lower casing described. I

6. In combination with the cover-back of a loose-leaf-holding book, a lower casing member, hinge members havin alined eyelugs, a hinge-rod passin throug said eyes, a support in the casin iiaving a medial seat for the eye-lugs and sloping sides, a spring on the rod engaging the hinge members and forcing them normally upon the support, hooked sections attached to the hinge members, havin' interlocking ends, .a cover-plate theedges 0% which are interlocked with the edges of the casing, and a lining secured to the cover-back and passing between the interlocking casing members, substantially as described.

In testimony whereof I have hereunto set my hand.
