4 Claims. (o1. 129-23) The present invention relates to loose leaf binders of the type 'having two binding members, one of which carries impaling posts or projections and the other of which carries locking means for engaging with the posts to hold the members together. An object of this invention'is to provide a strong durable construction with a fewer number of posts. Another object of the invention is to hinge the back piece and covers directly to the two strips of the binder members which carry the impaling projections and the openings through which the impaling projections pass to engage the locking means Still another object of the invention is to utilize a wear piece at the back of the binder for receiving the locking means for the impaling projections in order to eliminate the usual housing for this purpose.

To these and other ends, the inventionconsists of certain parts and combinations of parts.

all of which will-be hereinafter described: the novel features being'pointed outin the appended claims.

In the drawing: Y

Fig. 1 is a perspective view of a loose leaf binder embodying the present'invention;

Fig. 2 is a perspective view of the..transfer member;

Fig. 3 is an enlarged fragmentary view of the binder in open position;

Fig. 4 is a longitudinal section of the binder with the binder members locked together; and

Fig. 5 is a perspective view of the wear or protecting piece which houses the locking means. r In the illustrated embodiment of the invention,

there are provided two binder members.

One of these binder members comprises a strip 1 formed of a hard non-metallic substance such as leather board, hard rubber or similar materials. Secured to one face of this non-metallic strip by screws 2 is a metallic strip 3 whose length and width is less than the non-metallic strip so that the latter projects beyond the ends and the sides of the metallic strip. Impaling pins or proections 4 are projected laterally from the side of the metallic strip preferably being passed through the strip and upset on theinner face thereof. I

The other binder member comprises a nong metallic strip 5 formed of the same material as the '50 strip 1 and of the same length and width as the strip 1. This strip 5 has a longitudinally extending groove 6 out in the inner face thereof substantially throughout its length to form a chamber for a locking mechanism to be described, this chamber opening at one end and being closed at the other end. A metallic strip 7 is secured by screws '8 to the inner face of the strip 5 and over the groove to close the latter except at one end. This strip 7 has openings 9 which are adapted to receive the ends oithe impaling pins 4 of the other binder member. The length and width of the strip 7 is less than thatoi the strip dsothat the latter projects beyond the opposite sides and ends of the strip 7;

For locking the two binder members together, the pins 4 may be provided adjacent their free ends with shoulders 10, and with these shoulders may engage a locking barll which is arranged inthe groove 6 of the strip 5 and has a laterally turned portion 12 projecting from one end of the strip 7 but not beyond the adjacent end of the strip 5. A spring 13 acts on the locking bar normallyto hold portions thereof toone side of the openings 14 in the path of the shoulders 10 on the impaling projections 4.

A transfer member may be provided compris- I ing in this instance, a strip 15 provided with impaling projections 16 extending laterally therefrom.. Openings l7 may be provided in the strip 15 through which the impaling projections 4 may be passed to lock the transfer member in the binder.

The two binding members may be connected by aback piece 1 8 formed, in this instance, of sheet metal and having preferably hinged connection 19 with the metallic strips 3 and 7. In this instance, the hinged'connections are on the inner sides of the strips 1 and 5 so thatthe latter may project beyond the hinges and protect the same. At the same time the hinges are spaced from the ends of the strips 1 and 5 to protect the ends of the hinges. f The twobinding members may be considered as comprising upstanding metallic hinge members to the upper longitudinal edges of each of which a cover is pivotally connected so that it is free to swing and the lower longitudinal edges of which are pivotally connected at 19 to the backpiece 18. Each binding member includes the upstanding metallic hinge member along the inner side of which there extends the metallic strip as 3' or '7 and alongthe outer portion of which there extends the' non-metallic strip of protecting materialsuch as 1 or 5. Themetallic strip 3 is secured to the protecting strip 1 by means of the screws 2 which serve to clamp and secure the upstanding metallic hinge member in place between the metallic strip 3 and the'protecting strip 1. Likewise, the'upstanding metallic hinge member at the other side of the loose leaf binder is clamped or secured in place between the metallic strip I and the protecting strip 5. The protecting strip 5 functions to provide a receiving space for the locking bar on the one hand, it extends below the hinge member associated therewith on the other hand,v and is arranged in relation to the hinge member in such a manner that the hinge member serves to cover the groove whereby the locking member will be retained in place. It will be noted also that the non-metallic protecting strips 1 and 5 extend not only below the lowermost edges of the hinge members associated therewith but also below the backpiece 18 that connects the lower edges of said hinge members whereby the protecting members prevent the metallic parts from engaging the surfaces upon'which the loose leaf binder rests when in use.

Covers may be provided comprising in this instance, paper board pieces 20 having metallic hinging strips 21 secured to the inner edges thereof and hinged to the other edges of the strips 3 and 7 by hinges 22 which are situated beyond the adjacent edges of the strips 1 and 5 so that the covers may swing open Without interfering with said strips 1 and 5. The adjacent edges of the latter are-bevelled at 23 to facilitate this opening of the covers to the position shown in Fig. 1.

It will be noted that the binder has in the strips 1 and 5 wear pieces which will protect the metal back piece and the hinges between the binder members and the cover and the back piece both against side and end blows. The protecting or wear strip 5 serves to form the housing for the locking means heretofore mounted in a separate casing, The back piece and covers are hinged directly to the strip from which the impaling pins project, and also to the strip through which the impaling pins pass to be engaged by the locking means, thus reducing the number of parts heretofore required.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a loose leaf binder an outer, non-metallic protecting member having a longitudinal groove at the inner side thereof, a metal strip constituting part of a metallic hinge member which is placed against the inner side of the non-metallic protecting member and closing the groove thereof and provided with openings to receive loose leaf impaling pins, fastenings securing the metal strip to the non-metallic protecting member and extending across the groove thereof, and a locking barslidable in the groove of the said member and having elongated openings to register with the openings of the strip and to receive one of said fastenings to limit the movements of the bar, the latter having an end projecting beyond the strip and bent laterally to provide a finger piece, said non-metallic protecting member being secured in respect to the metallic hinge member in such a manner that the lower edge of the non-metallic protecting member extends below a pivotal hinge connection that is located at and along the lower edge of the metallic hinge member.

2. A loose leaf binder comprising two outer protecting members, one of the members having a longitudinal groove along the inner face portion thereof, metal stripssecured in place against inner faces of the members, one of the strips extending over and closing the groove of the member to which the groove-closing strip corresponds, impaling pins projecting from the other strip and extending through openings formed in the groove closing strip, a locking bar slidable in the groove and engageable. with the ends of the impaling pins projecting into the groove and having an end projecting beyond the groove closing strip and constructed to provide a finger engaging piece, and a metal back piece hinged to and located between the lower edges of the said metal strips, said protecting members being located so that they extend below the metal back piece.

3. A mechanical element for use in a loose leaf binder, which element comprises an upstanding hinge member having hinged along the upper edge thereof a cover member the free longitudinally extending edge of which cover can be swung downwardly and outwardly to open position and upwardly and inwardly to closed position, said hinge member having hinged along the lower longitudinal edge thereof aback member and which hinge member is normally upstanding when the binder is supported with the back member lowermost, said mechanical element having a longitudinally extending outer non-metallic protecting member having an inner portion thereof provided with a longitudinally extending groove open at its inner side except as covered by the upstanding hinge member, means for securing the non-metallic protecting member in place on the outside of the hinge member, said hinge member having an opening into and through which the free ends of shouldered impaling pins enter and pass, and a longitudinally extending locking bar located in the grooved portion and slidable into locking engagement with the free ends of the impaling pins when they are positioned so as to extend into the groove.
