This invention relates to loose leaf binders view of the ring holders of the form shown of the ring type wherein individual sheets, in F ig. Fig. 7 is an end view of the clips of pamphlets, bulletins and the like may be conthe form shown 'in Fig. 5; and Fig. 8 is an veniently insert'ed and removed. It. is pareievaton of the form shown in Fig. 5, look- 5 ticularly well adapted for use in the binding ing between the sides of the cover.

The rings 2 may be of partly broken away; Fig. 8 is an end view; any openable form'which hasv a hinge or Fig. Li is a plan view showing the binder in joint at one portion and which is adapted to development and without the rings; Fig. 5 open'at'a point diametrically opposite the is an end view of a modified form with the hinge or joint. These rings of various forms sizes and may be purchased in quantities at low cost and of a size to suit the particular requirements.

It is evident that this form of construction is readily adaptahle for any size of binder as regards length or thickness by merely making the main element lV of the required length and width. lt will lilewise be understood that any desired number of clamping lips la may be provided to insure the holding of the cover` permanently in position; and likewise any desired number of the cars 1d may be provided for the receipt of any number of rings 2. It is also. evident that the cover may be of any ordinary thickness and of any material withoutmodification of the element l or of the projections 1a and 1b. If the cover be of such thickness or Character that it cannot be easilj.Y piereed by the projections 1a and 12), the cover may be cut to -form slots in the proper locations to receive these projections when uniting the cover with the main supporting element. t is also evident that this form of construction permits the use of a cover having` the same thickness throughout and does not require any reenforcement or additional layers of material at the back. If desired, the binder may be used without the cover, in which case the projections 1a become unnecessary; but for the most purposes, such as catalogs or bulletins, a decorative cover is used of a character to protect the bulletins or catalogs and this cover, as already explained, is clamped in place to the main element 1, while permitting the convenient insertion and removal of individual sheets or pamphlets by means of the rings 2.

lnstead of using bendable material i" or the main element 1, this element may be made of any stiif unbendable material such as celluloid, fiber and the like, in which case the construction shown in Figs. 5 to 7 may be utilized. Here this main element is indicated as a flat plate or strip t and is not provided with the integral projections 1a or 1b. Instead of the projections, 1a, a bendable metal clip 5 is utilized, the ends 5a thereof being passed through the cover and bent inwardly to clamp the cover to the plate, as indicated in Fg. 5. The projections or ears 1b are replaced by the ring` holder 6 of the form shown in Fig. 6. This comprises a metal strip or clip which is crimped inwardly near its ends as shown at Ga after its projecting parts 6b have been passed through the cover and thus serve to secure the ring holder in position, as well as to clamp the cover to the back plate. The perforated projections GZ) are then bent at a suitable angle to receive and support the cally manufactured and readily assembled,

as well as being conveniently and easily made to suit any particular requirements. Although preferred embodiments of this invention have been shown and described, modifications may be made without departing from the scope of the invention.

I claim:

1. A loose leaf binder comprising a main element having inwardly projecting oppositely located perforated projections, and inwardly extending clamping projections, rings passing through the perforations, and a cover clamped to said main element by said clamping projections.

2. A loose leaf cover comprising a back plate, perforated oppositely located ring supports extending inwardly at an angle from said back plate, and rings carried by said supports.

3. A loose leaf cover comprising a back plate, perforated oppositely located ring supports extending inwardly at an angle from said back plate, rings carried by saidvsupports, a cover located against the inner surface of said plate, and inwardly extending clips for holding said cover against said plate.

A loose leaf binder comprising a back plate having` a series of projecting lips and oppositely disposed inwardly extending perforated cars, a cover clamped between said lips and said plate, and rings supported by said cars and passing through the perforations thereof.

5. A loose leaf binder comprising a back plate, a cover having its back portion located against the inner side of said plate, a plurality of clips extending around the outside of said plate and elamping the cover against the inside of said plate and having oppositely disposed inwardly inclined perforated projections, and a plurality of rings carried by said projections and passing through the perforations thereof.

6. A loose leaf binder comprising a back plate, a cover having its back portion located against the inner side of said plate, and a plurality of clips extending around the outside of said plate and having inwardly ez:- tending projections for clamping said cover against the inside of said plate.
