i Application'file d July 3, 19535. Serial No. 421,379.

To all whom itwmg concern:

Be it known that I, RICHARD M. VAN VALKENBURGH, a citizen of the United States'residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Binders, of which the. following is a complete specification.

This invention relates to improvements in binders and has particular reference to temporary or'loose-leaf binders-having a binder member carrying posts for ieceiving the leaves.

his well known in this art that the binder member, which carries the leaf holding posts, is bound with the suitable material before the end caps are placed in position. It is also known that the usual method of positioning the end caps causes the binding material to peel back along the body of the binder member as the cap is placed on each end thereof.

In view of the above mentioned disadvantages and the recognized desire to create a neater, more substantial binder member, it

is the primary object of this invention to provide a member which has means for guiding the edges of the binding material while the end caps are being placed.

A further object of the present invention is the provision of a binder member having means for protecting said binding material as well as to securely hold the end caps ter they are once pressed into position.

Further objects will appear during the course of the detailed specifications in which the many novel features are set forth with reference to the accompanying drawing, illustrating but one embodiment of the invention.

Figure 1 is a perspective view of a binder member iPIOVlClGCl with the improvement.

Fig. 2 is'a cross section of the same taken on line IIII of Fig. 1.

Fig. 3 is a fragmentary vertical longitudinal section of the binder member taken on line IIIIII of Fig. 1.

Fig. 4: is a fragmentary view of one end of the improved binder member showing one end cap ready to be placed in position.

Fig. 5 is a fragmentary vertical section of one end of the improved binder member showing the cap before the edges are pressed inwardly to engage the binding material, and,

*Fig'. 6 is an end view of the binder member with the cap removed.

i imilar reference characters parts throughout the several views, and the numeral 7 designates the binder member which is formed of metal and may be hollow as shown.- 'As is well-known, the leaf engaging posts '7 are carried by thismember and acover is hingedly connected thereto at points 7".

Both-ends of binder member 7 are flared to provide an outwardly extending flange 8 of progressively increasing periphery, which extends entirely around the ends of member 7. The degree of outward flare of flange 8 may be varied as desired and tosuit the thickness of various kinds of binding material 9 which encircles member 7 between the points of beginning of flanges 8. If a heavy or thicl: material 9 is used, the flange flare should be increased. To properly construct the binder member, outer edge 10 of flange 8 must beabove the plane of the outer surface of binding material 9. It is essential also, that material 9 terminate, as shown in Figs. 3, l and 5, at the point of beginning 11 of flange 8. I

After binding material 9 has been affixed to member 7, caps 12 are placed over each end thereof by allowing them to slide over outer edge 10. These caps 12 should fit snugly yet not engage binding material 9 as they are being forced into position, and it is clearly shown in Fig. 5 that the material is not touched until the edges 13 of cap 12 are pressed inwardly as shown in Fig. 3.

The showing of the invention in the accompanying drawing is somewhat exaggerated to more clearly point out the invention.

In practice, the result attained, time and labor saved and finished appearance is most desirable. The spoiling of binder members and the necessity of recovering with binding material is entirely eliminated, and the general appearance of the end caps is greatly improved.

I do not limit my invention to the structure shown and described, as many modifications, within the scope of the appended claims, may be made without departing from the spirit of the invention.

lVhat I claim is:

1. In a binder, abinder bar adapted to support sheet engaging posts, comprising a body having its ends flared.

refer to like in a binder, a binder bar adapted to support sheet engaging posts comprising a body having its greatest periphery at its ends.

3. In a binder, a binder bar adapted to support sheet engaging posts comprising a body having an outwardly extending flange at each of its ends.

i. In a binder, a binder bar adapted to support sheet engaging posts comprising a hollow body having the Walls thereof flared outwardly adjacent each end of said body.

5. In a binder, a binder bar comprising a body encircled by binding material and having each end thereof adapted to protest the edge of said binding material as an end cap is being placed in position.

6. In a binder, a binder bar comprising a body having each of its ends flared and a binding material encircling said body between said flared ends whereby an end cap may be positioned Without engaging the edge of said binding material.

7. In a binder, a binderbar comprising a body having an outwardly extending flange at each of its ends, binding material encircling said body between the points of beginning or said flanges, the outer periphery of said flanges being greater than the outer periphery of said encircling binding material.

8. In a binder, a binder bar comprising a body having an outwardly extending annular flange of progressively increasing periphery at each of its ends, binding ma terial encircling said body between said flanges and an end cap supported by each of the flanges having its edges pressed inwardly to engage said binding material.

In testimony whereof I hereunto my signature this 26th day of June, 1925. RICHARD M. VAN VALKENBUBGH.
