LbosE-LEAE BINDER.4

Application filed March 29, 1926. .Serial No. 98,349.

The present invention is concerned with a loose leaf binding device which may have a wide range of utility for binding blank leaves or for filing either single leaves or folded letter sheets.

An object of the invention is to provide a device of this character so constructed that the leaves will be securely retained in position within the folder and arranged to facilitate the insertion' or removalof the leaves when such insertion or removal is desirable.

A further object of the invention is to provide a spring pressed retaining plate for the leaves which may optionally serve as a tearing guide in the event that the device is used as a note book.

Further objects of the invention 4are to provide a loose leaf folder of simple, practical construction, which will be ruggeddur able and efficient in use, neat and attractive in appearance, capable of housing` letter sheets in compactly folded position, and `a binder which may be manufactured and assembled with comparative economy.

llVith the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter' set forth and pointed out in the claims. The invention may be more drawings wherein- Flg. 1 1s a plan view showing the binder in open position, and the spring pressed retaining plate folded over to act as a tearing guide for a sheet of material.

Fig. 2 is a view partly in end elevation of Fig. 1, and partly in transverse section on the line 2 2. y

While the folder of the present invention may be made of either flexible or stiff back form, 1 prefer to use a pair of stiff covers 10 and 11 connected to a stiff intermediate bach 12 by the use of strips Aof hinging material, such as the canvas strips 13 which may be pasted over both the inner and outer faces of the backing element 12 and over the adjacent edges of the covers 10 and 11.

Backing element 12 is preferably formed with a pair of openings reinforced by eyelets 14. An eyelet is provided adjacent each end of the backing element 12 and the sheets of material to be filed indicated at 15 are necessarily of a width less than the distance between the eyelets.

Additional eyelets 16 may be formed in the cover 11,. near the hinged edge thereof pressed retaining plate 17, the free edge 18 of which may conveniently serve as a tearing guide, as best seen in Fig. 1.y

The retaining plate is preferably of slightlly greater width than the sheets 15 which are received in the folder, and is formed at each edge with an integral tubular guideway 19. These guideways accommodate contractile coiled springs 20. One end of each coiled spring is anchored to a stud member passed through the eyelets 14. As shown in the drawings these stud members may conveniently include heads 21 of greater diameter than the eyelets, `and eyes 22 pro- Jectingy through the eyelets and engaged with the ends of the springs 20.' The opposite ends of the springs 20 are hooked over lugs or ears 24 deined at the edges of plate 18 by recessing the plate edges at 25 and notching them at 26.

In assembling the device, the coiled springs 2O are attached to the studs, passed through the sleeves 19, and hooked over the lugs When it is desired to insert a letter sheet under the retaining plate 17, itis merely necessary to manually grasp the plate and pull it away from the backing member 12, springs 20 yielding so that sufficient clearence is provided under the plate for the insertion of a sheet.

The purpose of the eyelet 16 is to facilitate the filing of single'sheets of a size slightly less than one of the covers of tht` binder. In this instance the studs will be passed through the eyelets 16 and anchored to the springs 20, and the plate 17 will serve to yieldingly clamp the inner edge of single sheets (by which I mean sheets of half the size of th'ose shown) against the cover 11, as

will be readily understood.

The principal reason for malringthe plate 17 relativelyvwide is so that it may be used as a tearing guide as shown in Fig. 1, wherein the line upon which one of the sheets 15 will be tornis indicated in dot and dash. The device is peculiarly elficacious as a letter lll() sheet filer, because it willperniitthe letterheads to be readily thuinhed over and ei;- posed, and at the same time retain. all of the letter' sheets in coinpaetly folded'condr.

.3 tion when the binder is closed.4V T he Aordinary letter file would he at least, twice the size of the present folder.

lVhile have illustra ed. one of thepreferred embodiments of the invention, vari- .lo ous changes and alterations might be made in the general form and arrangement of parts described Without departing-from the invention. Hence l do not Wish to limit myself to the details set forth, but' shally con- I-'i sider myself at liberty to make such changes and alterations as fairly fall `Within the spirit and scope of the appended claims.

I claim: I l. A filing folder of the class described includinga pair of stiff covers, a stiff ha .i hingedly connecting thepeovers, a plate rhsposed parallel to and adjacent the line of hinging` of thel covers, and springs actingl on the ends of the plate and anchored to the folder' to retain the plate spring-pressed into engagement with loose leaves in the folder, one of said covers having` eyelets near the edges thereof adapted to receive anchoring devices for the springs.
