BINDER-FILE.

Specification of Letters Patent.

Patented Feb. 27, 1906.

To all whom it may concern.-

Be it known that I, CHARLES R. NELSON, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have inventedcert ain new anduseful Improvements in Binder-Files, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to that form of binderfile comprising a base-plate from which rise posts upon which the sheets to be filed are impaled, a binding-plate being attached to the posts above the sheets. The invention is particularly applicable to devices of this kind adapted to carry blocks of sheets of substantially uniform thickness, and especially sheets, such as bank-checks, having stubs from which the body portion of the sheet is to be torn.

The object of the invention is to simplify the construction and action of devices of this kind and it consists generally in a baselplate or board, a pair of filing-posts rising from this base-plate and having lateral notches, and a spring binding-plate apertured to receive the posts and adapted to engage their notches to compress the sheets upon the board.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a detail plan view of the binderfile open. Fig. 2 is a detail longitudinal section of the same on the line 2 2 of Fig. 3, the position of the cover-plate when closed being shown in dotted lines; and Fig. 3 is a sectional view on the line 3 3 of Fig. 1.

The base-plate 10 may be of any suitable material, such as tar-board, and will take approximately the shape of the sheets intended to be filed. A metal plate 11 is secured to the upper face of the plate 10 across its upper or inner end, and from this plate rises a pair of posts 12 13, each having lateral notches, as represented at 14 and 15, and one of the posts, as 12, is of flattened form, its wider dimension being preferably transverse as to a line joining the posts.

A binder-plate 16, of spring-metal, is provided and has apertures 17 and 18 for receiving the posts 12 and 13, respectively. The aperture 17 is slotted and of proper size to receive the post 12, the slot, however, extending normally at an angle to the wider dimension of the post, so that it is necessary to turn the plate to an angular position to pass it over the post. As shown in the drawings, the aperture 17 extends longitudinally as to the plate, it being necessary to turn the plate to a position transverse to a line between the posts to pass it over or remove it from the post 12. The width of the aperture 17 is suflicient to permit the plate being returned to its normal position when the margins of the slot are in register with the notches 14, and it will be readily understood that the plate and the post are then so interlocked as to prevent any vertical movement of the plate on the post. The aperture 18 is of substanti ally the size and shape of the post 13.- Aslot 19, however, opens out of it, leading toward the aperture 17, the slot being narrower than the diameter of the post, but of sullicient width to receive its contracted portion by engaging with the notches 15. The apertures 17 18 are spaced apart a slightlygreater distance than are the posts, and the plate 16 is preferably normally straight. In order therefore to apply it to the post 13 after it has been secured to the post 12, as previously described, it must be bowed, as indicated by dotted lines in Fig. 3. When placed in position and allowed to assume its normal form, it slides along the post, so that the notches 15 become engaged by the margins of the slot 19, and the bound sheets are securely held in place.

In order to remove the sheets from the binder, the middle portion of the plate 16 is raised, so as to bring it to the bowed form, and thus slide it on the posts until the slot 19 comes out of engagement with the notches 15, when the forward end of the plate may be readily lifted from the post 13. Then by turning the plate to a position substantially at right angles to its normal or operative position the inner end may be lifted from the post 12.

Preferably, though not necessarily, the binder is provided with a cover-plate 20, secured to the plate 10 by a flexible hinge 21 of sufiicient width to allow the cover-plate to fold over the top of the posts 12 13, as indicated by dotted lines, Fig. 2. The plate 11 may be secured to the plate 10 in any desired way. In ordinary practice the material of which the hinge 21 is formed may be continued to cover the plate 11 and secure it in place, as shown.

By providing each post with a plurality of notches, as shown, the file may be adapted for binding a greater or less number of sheets.

Obviously the post 12 might be of other irregular shape than that shown in the drawings without departing from the invention.

I claim as my invention 1. In a binder, in combination, a base plate; a pair of posts rising therefrom a binding-plate slidable upon one of the posts when transverse to a line through the posts, and adapted to positively engage both posts when in alinement therewith.

2. In a binder-file, in combination, a baseplate; a pair of posts rising therefrom; and a flexible binding-plate for engaging the posts normally fixed in position but vertically movable 011 one of the posts when flexed and on the other post only when turned at an angle from its normal position.

3. In a binder, in combination, a baseplate a pair of posts rising therefrom and having lateral notches; a spring-plate apertured to receive the posts and adapted to run on one thereof, only when transverse to a line uniting the posts, the aperture for receiving the other post being prolonged at less than the major diameter of the post, the spacing of the apertures and the posts being different.

4. In a binder, in combination, a baseplate a pair of posts rising therefrom, one of the posts being fia'ttened and having lateral notches, the greater diameter of such post being in a direction transverse to a line through the posts; and a binding-plate having, adj acent one of its ends, an aperture elongated longitudinally as to the plate for receiving the flattened post and of sufficient width to receive its contracted portion by engaging the postnotch, the opposite end of the binding-plate being adapted to positively engage the other post.

5. In a binder-file, in combination, baseplate; a pair of posts rising therefrom and having lateral notches, one of the posts being flattened and having its greater diameter in a direction transverse to a line between the posts; and a spring binding-plate for engaging the posts having, adjacent one of its ends, an aperture elongated longitudinally as to the plate for receiving the flattened post and of sufficient width to receive its contracted portion by engaging the post-notch, and adjacent its opposite end an aperture for receiving the other post and prolonged by a slot of less width than the diameter of such post, the distance between the apertures being different from that between the posts.
