LOOSE-LEAF BINDER.

Specification of Letters Patent. Patggntgd NQV. 29?, 1921.

Application ruea August 24, 1920. Serial in. 405,649.

To all whom it may concern:

Be it known that I, WILLIAM Finn) DUNN- ING, a citizen of the United States, and resident of the city of Washington, in the District of Columbia, have invented certain new and useful Improvements in a Loose-Leaf Binder, of which the following is a specification.

My invention relates to a loose leaf binder,

and more particularly to a loose leaf binder to hold individual loose sheets, and so constructed as to permit ready access to any of said sheets.

A binder constructed in accordance with my invention will permit any number of individual sheets or cards, within the capacity of this device, to be securely fastened and at all times permit ready removal of any sheets or cards without displacing the remaining ones. M

One object of my invention is to provide a binder which employs straight prongs or more apparent in the specification and in the drawings, in which Figure 1 is a fragmentary perspective Fig. 2 is a rearv elevation of the back of the binder in open position, y

, Fig. 3is a sectional view taken on line 3--3 of Fig. 2,

Fig. 41 is a vertical transverse section of the binder in closed or locked position,

Fig. 5 is a section taken on line 55 of Fig. 41, I

Fig. 6 is a front elevation of the back of the binder in open position, and

Fig. 7 is a horizontal section taken on line 77 of Fig. 5.

Referring now more particularly to the drawings in which 10 indicates the sides or covers-of the binder, and 11 metallic stripsv disposed adjacent one end of each of the cover pieces 10. These metallic pieces may be connected in any suitable manner to the cover pieces 10 which will provide a flexible connection, and I have here illustrated this connection being made by the linen covering of the binderwhich will extend around the cover pieces 10 and the metallic strips 11 and aorossthe back of the device as indicated at 12, providing a covering for the working parts thereof. 1

Adjacent the back of the binder to which this invention relates, there are transversely disposed plates 13 secured in any suitable manner to the metallic strips 11., Secured to these plates 13are binding posts or pins 141. These binding posts or pins are straight and project right-angularly from the plates 13. The posts onthe opposite plates are offset from one another to enable them to come into alinement with the series of apertures contained in the leaves or sheets used in connection with binders of this type.

The inner edge of each ofthe plates13 is provided with curved lips15 which encircle hinge rods 16. Right-angular lips or pro; jections 17 are also formed on the inner edge of each of the plates 13. All of this is for a purpose to be more fully hereinafterdescribed.

A pair of sliding back plates 18 have similarly formed curved lips 19, which encircle the hinge rods 16 to hingedly connect each of the plates 13 with one ofthe sliding backplates 18. This is clearly illustrated in Figs.

1, 2 and 3. The back plates 18 are provided a with recesses, or cut-out portions, 20 to accommouate the right-angular l1ps17. It 1s apparent that while the hinge connection between theplates 13 and 18 allows relative movement thereof, this movement is limited in one direction by the angular lips 17 com ing in contact with the sliding back-plates 18. When these lips 17 are in contact therewith, the plate 13 and the appurtenant parts thereto are at right angles to the back of the binder and the pins 1% are vertically disposed and in alinementwith-the apertures 'of the sheets or cards. In this connection the metallic strips 11 are extended beyond the hinged connection between the plates 18 and 18 as indicated at 21 and thereby afford a stop for the covers or sides of the device in the other direction.

Extending longitudinally or the back is a a pair of locking plates 22 which cover the overlapping edgesof the sliding back-plates 18. The sliding back-plates are each provided with a pair of vertically disposed slots v the binding and passing through these slots are studs 24, which studs are rigidly secured in the pair of locking plates 22. These studs, therefore, provide guide members for the movable back plates 18 and limit the travel of these back plates, in a manner to be more fully hereinafter described.

The vertical edges of the pair :of locking plates are provided with cutaway portions or looking recesses 25, while thevertical edges of the sliding back-plates 18 are provided with looking notches 26 and beveled surfaces 27. i V r V Mounted upon the rear plate of the pair of locking plates 22 is the locking mechanism. This comprises two longitudinal locking bars 28 provided near their outer ends with slots 29 through which pass studs 30. These studs 30 are rigidly mounted in the rear locking plate 22-and provide a guide for the outer end of each of the locking bars 28. The inner ends of the locking bars are pivoted as at 31 to a link 32 pivoted as at 33-to the lockingpla'te 22. A. coil spring 34, or spring of any'other suitable nature, has its ends connected to one of the lockbars 28, as indicated at 35 and to an intermediate portion of the other locking bar, as indicated at 36. This spring, therefore, retains the lockin bars inthe position illustrated in Fig. 2 in which position they are at the limit of their inward travel, and are in locking position. The outer end of each of the locking bars 28 is provided with a rightangular projection or'latch '37 which lies within one of the recesses 25 at each end of the locking plates 22,'and is adapted to ride over the beveled edges 27 of the sliding back-plate l8 and to snap in the notches 26 of these sliding back-plates when these notches are properly positioned. I

An operating link 38 is fastened to one of the locking bars 28 and terminates in a thumb piece 39. Therefore, when pressure is applied to the thumb piece 39, the link 32 will be rocked, forcing the latches 37 outwardly to free the sliding back-plates '18. .7

In order to throw the back of the binder open and the binding posts 14; apart, springs 40, are provided having each of their ends secured in one of the sliding back-plates 18, respectively. By this construction, when the sliding back-plates are freed by reason of the release of the latch 37 the sliding back-plates 18 will move in opposite directions with respect to one another, carrying posts out of operation or binding position.

I will now proceed to describe the operation of my improved binder. When it is desired to insert the cards or sheets, here indicated by theletter C, the device may be made to'assume the position illustrated in Fig. 1. With the cards in position upon one side'on the binding posts 14, the other side or cover, and its corresponding binding posts, will be swung on its'hinge until the posts 14: assume a vertical position'and are in alinement with apertures of the cards C. The correct position of the binding posts is assured by reason of the angular projections or lips 17 carried by the plate 13. As these lips 17 enter the recesses 20 in the back-plate 18 the motion of the plate 13 and pins 1 1 is arrested and the pins 141 are in a position to enter the apertures in the cards 0. Vertical pressure thereafter; applied to the back of the binder will cause the two sliding back-plates 18 to move inwardly toward one another between the locking plates 22. During this action the bevels 27 lips 17 have passed between the locking plates 22, thereby preventing the plates 13, carrying the pins '14:, from being moved on their pivots 16 until the sliding back-plates '18 have been freed and allowed to move sufli ciently from between the locking plates 22 to again free the angular lips 17. 7

By this construction, when the pins 1 1 have entered the apertures in the cards or sheets andthe device has been locked, the binding posts or pins 14: will securely retain the cards in place. The device may be unlocked by pressure upon the thumb piece 39 which, by reason of the link 32, will cause both latch bars 28 tomove outward simulta neously and lift the latches 37 out'of the notches 26 in the sliding back-plates 18.

It should also be noticed that this binder cannot be made to assume its locking position without the binding posts 14 first having been properly alined and inade'to. enter and modifications may bema'de in the details of my invention without departing from the spirit and scope thereof and I, particularly reserve this right.

Having thus described myiinvention, what I claim is: 1' j 1. A device of the class described comprising side .members, a back comprising relatively movable plates for opening and closing said device, post-carrying members hinged to said plates, and straight binding posts carried by said members, said postcarrying members and plates being adapted to cooperate to position said posts in spaced parallel relation when the device is in closed position.
