TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 752,559, dated February 16, 1904. Application filed September 2,1903. swarm. 171,670. on model-l To all whom it may concern:

Be it known that I, MARK PIERRE J AOKSON, of Newton Center, in the county of Middlesex following is a full, clear, and exact description thereof, reference being had to the accompany ing drawings, which form part of this specification.

The present lnventlon is an lmprovement in temporary binders for securing detached leaves in book form, and is in particular an improvement upon the binder shown and deto the backing-pieces A B in such manner that scribed in Letters Patent No. 7 35,87 9, issued to me the 11th day of August, 1903.

The object of the present invention is to provide a binder which will remain securely closed, to provide a simple device therefor by which it is positively locked when closed, and in particular to improve my aforesaid patented binder by doing away with, the sliding connection between the spring and hinge-back of binder and by providing a positive but removable look for such binder.

The invention consists in the novel constructions and combinations of parts hereinafter described and claimed, and the accompanying drawings illustrate various but not all constructions embodying my invention.

In said drawings, Figure 1 is an inner face view of the preferred form of binder with the locking device in place.

are similar sectional views illustrating modifications in relative shapes and sizes of the Fig. 2 is an enlarged section on line 2 2, Fig. l, and showing indotted lines the position of parts when lock is re-,

moved and binder opened. Figs. 3, 4:, and 5 tion and will hold the edges of leaves or sheets inserted between the pieces A B; a indicated in the drawings. To the inner opposed faces of said backing-pieces are attached impalingposts or filing-fingers D, which may be of any desired kind and arranged in any desired way, provided they will hold and retain the sheets in place when the binder is closed thereon.

As shown, the fingers are of the telescoping variety and curved on arcs. concentric with the hinge C; but I do not restrict myself to the specific construction of leaf-retaining devices shown.

A spring is arranged between and connected l it will hold the binder closed,preventing leaves escaping from the filing-fingers, as shown in full lines in the drawings. This spring may be formed of wire, as shown at E in Figs. 1 and 2 of the drawings, this spring being substantially like that shown in my said patent, butis permanently attached at its bend c to the backing-pieces A instead of being loosely attached thereto, as in my said patent. In the present instance this spring is only intended to perform the function of closing the binder, and therefore it may be a simple bowspring, as at E, Fig. 3, having its ends secured to the pieces A and B near their bends,

and one or more such springs can be used, as

desired. Figs. 4: and 5 show how shorter bowsprings may be used for same purpose. All these springs serve the same functionto wit, to close and hold closed the binderand are put under tension when the binder is open.

In Fig. 3 the backing-pieces A B are so formed that when closed the back of the binder will be bulged outwardly or convex in crosssection.

In Fig. 4 the backing pieces A B are straight in cross-section, the filing-fingers beingmade longer and of greater curvature than in Fig. 2.

In Fig. 5 the backing-pieces A B are slightly curved in cross-section, which reduces the curvature of the fingers D.

In those constructions where the back when closed is bowed outwardly-as in Figs. 3 and 5, for instance-the springs are contractile. In constructions where the back is straight when closed, as in Figs. 4 and 8, the springs may be expansive, either expansive or contractile springs being within the scope of my invention, and in any case the springs should be such as will perform the principal function of holding the filing-fingers in closed position.

In each of the Various forms of binders shown it will be noted that when the binder is closed the spring is bowed away from the hinge of the backing-pieces and when the binder is opened the spring is brought against the hinge of the backing-pieces, as indicated in dotted lines in Fig. 2. In order to efiectually lock the binder when closed and prevent its casual or forcible opening, I employ a simple but efiective locking device, consisting of a rod or bar E which is of such cross-section as to fit closely between the spring and the backing-pieces when the binder is closed, as

indicated in the drawings, and which by preventing the hinge approaching the spring effectually and positively locks the binder in closed position until the block is removed. This locking-block may be in the form of a bar long enough to reach from one end of the binder to the other, at least to and beyond the springs, so that it can be slipped into the binder and through the spring after the binder is closed. The locking device should fit sufficiently tightly to prevent its casual displacement or dropping out of place while the binder is being transported in closed position, but may be readily grasped by thumb and fingers and withdrawn when it is desired to open the binder. It will be seen from the drawings that the cross-section of the locking device may Vary with the form of the opening inclosed between the spring and backing-pieces when the binder is closed. In the locking device shown in Figs. 6 and 7 the wire G is fastened near or at the hinge C and may be used as the pivot of the hinge. At one extremity this wire is bent in convenient form, as at g, to form a crank by which the wire may be turned. At another place or other places along the center, opposite the spring or springs E,this wire is bent in a U shape, as at g, so that when the wire is turned down by the use of crank g the projected portion of the wire at 9 will come against the adjustingspring E and hold it in the closed position, as shown in Figs. 6 and 8. When the loop or U-shaped projection g of the wire is thrown back against the backing-piece, as in Fig. 7

the binder can be readily opened, as when the rod F is removed in the preferred locking device. It will also be noted that the particular kind of spring employed and the particular form of the binding-pieces are not essentials of the invention, it residing more particularly in the employment of a locking device between the spring and backing-pieces when the binder is closed to prevent the opening of the binder until the locking device is moved out of the way.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-' 1. In a temporary binder, opposite longitudinally-hinged backing-pieces provided with filing-fingers, and a spring attached at its opposite ends to the said backing-pieces, on the inner sides thereof, and adapted to close the binder; with a locking device adapted to be adjusted between the spring and backingpieces when the binder is closed, to prevent opening of the binder, substantially as described.

2. In a temporary binder, the combination of a pair of backing-pieces hinged together longitudinally, filing devices attached to said pieces and a spring attached to the opposite backing-pieces on the inner sides thereof, extending across the hinge, and adapted to close the binder; with a locking device adapted to be adjusted between the spring and backingpieces when the binder is closed, to prevent opening of the binder, substantially as described.

3. In a temporary binder, the combination of a pair of backing-pieces hinged together longitudinally, a bowed spring attached at opposite ends to the opposite backing-pieces and extending across the hinge; and sheet-filing devices attached to the respective backingpieces; with a removable locking-bar adapted to be inserted between the spring and backing-pieces when the binder is closed, to prevent opening of binder, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

MARK PIERRE JACKSON.
