Application May 12, 1951, Serial No. 226,028

1 Claim. c1. 40-402 The present invention relates to improvements in a loose-leaf suspension binder, and its principal object is to provide a loose-leaf binder adapted for suspension from a wall or any other suitable support in such a manner that any one of a stack of leaves may be turned over from one side to the other for exposing to view pictorial or printed matter displayed thereon.

My loose-leaf suspension binder is principally intended for use in educational work, as in a classroom or in lecture rooms, wherever it is desired to render the information exhibited on the various pages of a loose-leaf binder available for immediate inspection,

More particularly it is proposed to provide a loose-leaf suspension binder of the character described in which each of the loose leaves is supported at two points, whether supported on the left side or on the right side of the binder and may be readily swung from one side to the other.

It is further proposed in the present invention to provide a loose-leaf binder arrangement of the character described which may readily be used in connection with relatively small sheets such as are conventionally used in loose-leaf binders, and also with much larger sheets such as maps, large pictorial illustrations, and practically any size sheet conventionally exhibited on the wall of a classroom or a lecture room.

It is further proposed to provide a loose-leaf binder of the character described in which sheets or leaves may be readily added or removed without disturbing the suspension arrangement and with a minimum of effort.

Further objects and advantages of my invention will appear as the specification proceeds, and the novel features of my invention will be fully defined in the claim attached hereto.

The preferred form of my invention is illustrated in the accompanying drawing, in which Figure 1 shows a front view of my loose-leaf suspension binder as applied to a vertical surface,

Figure 2, a bottom plan view of the same, certain portions being shown in section, and

Figure 3, a section taken along line 33 of Figure 2.

While I have shown only the preferred form of my invention, I wish to have it understood that various changes and modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.

Referring to the drawing in detail, my suspension binder comprises in its principal features a backing 1, a pair of pegs 2 projecting forwardly therefrom near the ends of the backing, and a staple 3 mounted on the backing substantially midway between the pegs, and with the legs 4 and 5 of the staple arranged in alinement with the pegs.

The backing 1 is in the form of an elongated bar comprising two sections 6 and 7, both being straight and rectangular in cross-section, and the rear section 6 being somewhat wider than the front section.

rates Patent 0 F 2,755,579 Patented July 24, 1956 The two sections 6 and 7 are of the same length and the section 7 is superimposed upon the section 6 so to leave projecting flanges 8 adapted for securing upon the surface of a wall by means of screws passing through suitable perforations 9. The section 7 is secured upon the section 6 by means of screws 10.

Each of the pegs 2, which latter are mounted upon the backing with a slight upward incline as shown, cooperates with the near leg of the staple in supporting a stack of leaves indicated at 11, which latter for this purpose are formed with suitable perforations 13 near the upper edges thereof.

It will be readily understood that the leaves thus freely suspended may easily be swung about the staple from one side to the other for exhibiting to view educational matter disclosed thereon.

In order to provide for the easy insertion and removal of leaves or sheets I make a break 14 in the staple immediately above the leg 4, the leg 5 carrying the hook section 15 forming the body section of the staple. The two legs 4 and 5 are of substantially the same height as the pegs. The leg 4 is fixed with respect to the backing, but the leg 5 is pivoted in the backing as at 16 and is formed with an extension 17 swingable in a slot 18 in the forward section 7 and extending into a groove 18' in the rearward section 6. The groove 18 extends from one end of the backing to a point slightly beyond the location of the staple, and forms a conduit with the forward section. A rod 19 is movable longitudinally in this groove or conduit and has one end pivoted to the extension 17 as at 20 while the other end extends somewhat beyond the corrseponding end of the backing and is formed with a suitable handle 21. A spring 22 is coiled about the rod and bears at one end against a fixed washer 23 and at the other end against a shoulder 24 formed in the rod. This spring tends to push the rod into a position where it closes the staple at the break 14. If it is desired to open the staple for the adding or removing of leaves, the operator pulls on the handle 21 which causes the hook section 15 to swing about the pivot 16 and open both of the sides of the staple for the addition of new leaves or the removal of certain leaves.

The handle 21 terminates in a short upward extension 25 which may be made to bear against the outer end of the backing for locking the staple in open position.

The manner of using my suspension binder will be readily understood from the foregoing description. The flanges 8 are secured upon a wall or other vertical supporting surface by means of screws introduced through the holes 9. The handle 21 is then pulled outwardly and opens the staple at the break 14. Any desired number of sheets or leaves, within the capacity of the device, having first been properly perforated as at 13, may then be suspended on the left side by placing the apertures over the peg 2 and the leg 4 of the staple. The staple may then be closed by release of the handle 21, and the leaves may now freely be swung from one side to the other for exposing the desired subject matter disclosed thereon.

It will be noted that my device is very simple, can be readily made in any size necessary to accommodate desired material, and allows many sheets to be accommodated in a relatively small space while rendering each sheet available for easy inspection.

I claim:

A loose-leaf suspension binder, comprising an elongated bar having means for securing the same horizontally upon a wall or the like and having a conduit arranged lengthwise therein, pegs projecting forwardly from the bar near opposite ends thereof, a staple projecting forwardly from a central portion of the bar, with the legs 3 of the staple substantially in alinement with the pegs and of the same height as the pegs, the staple having a break at the upper end of one leg thereof and having means for opening the staple at the break, comprising a pivotal mounting for the second leg, an extension of the latter a leg projecting into the conduit, and a rod movable in the conduit and having one encl connected to the extension of the leg and its other end projecting beyond one end of the bar for swinging the second 1eg -on its pivot when the said end is pulled outwardly, the rod having spring means urging the same inwardly and having means coopera'ble with the said end of the bar for locking the same in its outward position.
